This post drill press has been made by Melbourne business, Dawn Manufacturing Company. It can be operated manually or by a pulley driven flywheel, with the aid of an engine connected to a power supply. In the late 1800s early 1900s a drill press like this would have been driven by steam from a boiler, the main power source for manufacturer’s power at that time. Dawn’s Golden Anniversary 1917-1967 Catalogue describes this model 611 drill as … “Ruggedly constructed with accurately reamed bearings. The coupling between the main spindle and feed screw engages the full circumference of the spindle, and embraces a ball-bearing thrust race. The pillar, as in all “Dawn Drilling Machines” is a solid bright steel bar, in place of the usual light tubing. Adjustable automatic feed.” And “F. & l. Pulleys extra, if required”. DAWN MANUFACTURING CO. The Dawn Manufacturing Co. was founded in Coburg, Melbourne, in 1917 by the four Blake brothers, who were all engineers. After World War I Dawn was supplying drills Australia wide and the company was growing at a healthy rate. During the depression they remained busy, with employees working 60-80 hour weeks. Dawn was contracted to supply vices and clamps to the Australian Defence Department and munitions factory during the World War II. - 1959 the company was taken over by G.N. Raymond Group. - 1967 the Dawn Manufacturing Co. had distributors in Australia and overseas, including USA, Canada, New Zealand, Asia and the Middle East. - 1973 the Siddons Ramset Limited acquired Dawn. - December 1991, Dawn became a unit of the United States owned Stanley Works Pty. Ltd. - November 1998 Dawn became 100 per cent Australian owned. The drill is a typical tool of a blacksmith, cart wright, wheelwright and garage business. It is an example of the tools of the blacksmiths’ trade in Victoria in the early to mid-20th century.Post type drill press machine with gear driven flywheel. Drill press is attached to a post and is fitted with a pulley belt and will run at a speed of maxim 200 r.p.m. The machine can also be manually operated.

The Mining & Geological Journal was produced by the Department of Mines, Victoria twice a year, during the period 1937 to 1972. It was an official publication of the Victorian Government, Department of Mines, devoted to issues and events surrounding mining and metallurgical engineering in Victoria along with education, research and innovations in mining. The journal also included advertisements and references to business interests. Editorial (page 3) discusses the imminent demolition of the Geological Museum, situated alongside the Old Treasury Building in Melbourne. The genesis of the Geological Museum was 'the Exhibition of 1861 when the potential value of scientific search to the community as a whole was recognised'. In 1887 the Secretary for Mines in Melbourne was strongly of the opinion that a School of Mines should be established...it was decided that a building should be erected to house a thorough staff of professsors to impart instruction.'

Two handwritten extracts from the Bendigo Advertiser 17/6/1910 regarding the inrush of water at the Victoria Quartz Mine. 'When the inrush of water came on Tuesday night, the men had to make a hurried exit from the bottom of the shaft and 4254 ft. plat. The working equipment left below consists of three rock-drilling machines, air-winch, two trucks, about one ton of drills, while rails, air-pipes, etc, below the 3224 ft. plat are not likely to be recovered'.

The invention of a hand drill is credited to Arthur James Arnot and William Blanch Brain of Melbourne, Australia who patented the electric drill in 1889. In 1895, the first portable handheld drill was created by brothers Wilhem & Carl Fein of Stuttgart, Germany. Hand-powered devices have been used for millennia. However, during the last quarter of the 19th century a radically improved generation of tools appeared. These tools took advantage of modern mass production machinery and processes (like interchangeable parts) and an increased availability in superior material (metal instead of wood). One of the outcomes included an array of new drilling machines. These human-powered tools were a vast improvement over earlier tools.This item is an example of a commonly used domestic tool - pre power tools.A Stanley hand drill with two wooden handles.

This drill once belonged to Goodall and Sons, who were blacksmiths in Terang. The smith was called upon to do a variety of work. In the early 1900s he was often the nearest person to be able to perform an engineer’s services for many miles around. The Dawn Ball-bearing Post Drill no. 611 is described in McPherson’s Catalogue as a “drilling machine with adjustable automatic feed, with improved Dawn coupler and ball-bearing thrust’. The heavy design of the flywheel enables it to maintain momentum” and is “fitted with pulleys for belt drive if desired” The hand crank drives an automatic feed to work off a cam-follow system opposite a large wheel.

Ltd., at both Terang (McKinnon and High Streets) and Mortlake (Dunlop Street). His business was in operation in at least in 1916 and perhaps well before, considering the date of the tyre bender and its use for wagons with wooden wheels. It was still in operation in 1953, chasing up debtors in Mount Gambier Court. Amongst the employees of H. Goodall & Sons Pty. Ltd. was Ernie Entwistle, a blacksmith (a soldier who died in 1916 ) and Alfred Hodgetts, radio expert (killed in a fatal accident in 1943, when he was in his early 30s ). Henry Goodall was involved in the community as a Justice of Peace, a deputy coroner, President of the Mortlake Hospital, trustee of the Soldiers’ Memorial Hall, and as a prominent Freemason. He and his wife had two sons (Charles and John) and one daughter (Mrs. Chas. Newton, of Skipton).

Hand Rail Drill Out on the track in the old days, it was sometimes required to drill some holes in a piece of rail so that two rails may be joined together by a metal joiner – called a fishplate. Before the use of generators and oxy cutting, the only way to do this was with a hand drill. This is the machine operated by two people, that would drill a hole in the rail. With two to three holes to be drilled in each rail end (ie 4 or 6 holes), it was a tiring, back breaking job. And then there was usually the rail on the other side of the track to be done!

Handwritten notes from a Bendigo Advertiser report, Thursday June 16th 1910. Management had for some time been apprehensive that the flooding in the deep mines to the south would affect them. Lansell's 180 took the precaution of baling. On the Tuesday night the men at the Victoria Quartz had a sensational experience. The storage dam at 3324 ft level receives the overflow from the flooded mines to the south. The level connects with the 3310 level at the Big 180. The water flows uninterrupted into thestorage dam which has a capacity of about 270 tanks. The dam had been emptied on Tuesday morning and work continued until 10 pm that night. The platman noticed that the water was coming down the shaft in a regular torrent. They didn't take much notice as they thought it was a leakinig outlet valve on the ascending tank. At 11 pm the releiving shift came down the shaft and said that the dam at 3,324 ft must be overflowing. The velocity of the water pouring down the shaft increased and the men made a hurried exit from the bottom of the shaft which is down 310 ft from the 4.254 ft plat (a total depth of 4,564 ft). An inspection of the dam at the 3324 ft level found it to be overflowing. By morning (Wednesday) the shaft had filled, and the water rose to 7 ft in the plat at 4254 feet. Mining inspector hgave orders that men were not to go below the 3324 ft level. Baling continued without cessation at the Big 180 all day and could not lower the water. Drilling machines etc and a powerful air winch at the 4254 ft plat are under water. An inspection made of the 3100 ft level at the 180 mine where the workings are connected with the New Chum & Victoria showed that water was running strongly from that mine proving that the inrush was due to flooded water from the southern deep mines to the south.

A black and white photograph depicting seven men and four women surrounded by tunnel boring machinery. A tunnel boring machine (TBM), also known as a "mole", is a machine used to excavate tunnels with a circular cross section through a variety of soil and rock strata. They may also be used for microtunneling. They can be designed to bore through anything from hard rock to sand. Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods in rock and conventional "hand mining" in soil. TBMs have the advantages of limiting the disturbance to the surrounding ground and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in heavily urbanised areas. The major disadvantage is the upfront cost. TBMs are expensive to construct, and can be difficult to transport. The longer the tunnel, the less the relative cost of tunnel boring machines versus drill and blast methods. This is because tunneling with TBMs is much more efficient and results in shortened completion times, assuming they operate successfully. Drilling and blasting however remains the preferred method when working through heavily fractured and sheared rock layers.This photograph is significant as it shows the machinery used and attire worn by men and women during the gold rush era.

The design of this and other similar treadle powered dental engine (or dentist drill) was in common use by dentists from the 1870’s into the 1920's. When electricity became accessible to most communities the electrically powered dental engines began to take over from the treadle power. Over the ages teeth were extracted using picks and scissors and other gouging instruments. Bow drills, hand drills and even a "bur thimble" drill were later used to prepare cavities for filling. Some drills were made bendable by attaching flexible shanks between the metal bur and the handle, giving access to the teeth at the back of the mouth. Other mechanical devices were introduced along the way, such as clockwork drills, but they were hard to handle and inefficient. Over the centuries “dentistry has been performed by priests, monks and other healers. This was followed by barbers; the barber’s chair may well have been the precursor to the dental chair. “(SA Medical Heritage Society Inc.) In 1871 James Morrison patented the first commercially manufactured 'foot treadle dental engine', the first practica dental engine although others had been introduced as early as 1790 (by John Greenwood). Handmade steel burs or drills were introduced for dental handpieces, taking advantage of the significant increase in the speed of the drill. In 1891 the first machine-made steel burs were in use. The treadle drill reduced the time to prepare a cavity from hours to less than ten minutes. In 1876 the Samuel S. White Catalogue of Dentist Instruments listed a 12 ½ inch wheel diameter dental engine, with 14 bright steel parts, for sale at US $55 In today’s market, this is the equivalent to US $1200 approx. The specifications of that dental engine are very similar to the this one in our Flagstaff Hill Maritime Village’s collection. It is interesting to note that workings of a similar treadle dentist drill were used and modified to power a treadle spinning wheel of one of the volunteer spinners at Flagstaff Hill Maritime Village. The foot treadle dental engine was a milestone in dental history. “Historic importance of treadle powered machines; they made use of human power in an optimal way” (Lowtech Magazine “Short history of early pedal powered machines”) The invention of a machine to speed up the process of excavation of a tooth lead to the invention of new burs and drills for the handpieces, improving speed and the surgical process of dentistry. They were the fore-runner of today’s electrically powered dental engines. This treadle-powered dentist drill, or dentist engine, is made of iron and steel and provides power for a mechanical dental hand-piece that would be fitted with a dental tool. The drill has a three footed cast iron base, one foot being longer than the other two. A vertical C shaped frame is joined into the centre of the base, holding an axle that has a driving-wheel (or flywheel) and connecting to a crank. A slender, shoulder height post, made from telescoping pipes, joins into the top of this frame and is height adjusted by a hand tightened screw with a round knob. On the post just above the frame is a short metal, horizontal bar (to hold the hand-piece when it is not in use). A narrow tubular arm is attached to the top of the stand at a right angle and can move up and down. At the end of the arm is a firmly fixed, flexible rubber hose protected for a short distance by a sheath of thin metal. At the end of the hose there is a fitting where the drill’s hand-piece would be attached; a small, silver coloured alligator clip is also at the end. A treadle, or foot pedal, is hinged to the heel to the long foot of the base, and joined at the toe to the crank that turns the driving-wheel. There is a spring under the toe of the treadle. The metal driving-wheel has a wide rim. Touching the inside of the rim are four tubular rings that bulge towards the outside of the driving-wheel, away from the pole, and all meet at the hub of the axle. The axle is bulbous between the inside of the driving-wheel and the frame then passes through the frame and is attached on the other side. The driving-wheel has a groove around which a belt would sit. The belt would also fit around a pulley on the arm, at the top of the post. The pulley is joined to a rod inside the arm and this spins the drill's hand-piece and dental tool holder. The two shorter feet of the base are made from a long metal bar that has been curved outwards, and its centre is bolted to the base of the pole. Under the ends of the curved legs of the base are wedge shaped feet. The driving-wheel is decorated in light coloured paint on both sides, each side having three sets of floral decals evenly spaced around them, and each about a sixth of the wheel's circumference. Similar decoration is along the sides of the frame. The foot pedal has decorative cutout patterns in the centre of the foot and at the toe. On the long foot of the stand is some lettering with a fine, light coloured border around it. The lettering is hard to read, being a dark colour and flaking off. There are also remnants of fine, light coloured flourishes. The foot pedal has lettering of the maker’s trade mark cast into the metal at the ball of the foot. Lettering on the base is peeling and difficult to read. The foot pedal has a trade mark cast into it that looks like a combination of ‘C’ , ‘S’ , ‘A’, ‘R’. flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, dentist, teeth, dental drill, dental engine, treadle drill, foot powered drill, treadle engine, orthodontics, dental surgery, james morrison
