INSTRUMENT roR'sUrrLYING COMMINUTEDVGOLD BY Arn-rnnssunn.
' App1icati0n filed Ja ua y 3, 192,9. s ri ifisiaf aie a4,
Be it known that I, FRE' Euro PRATT, a citizen of the Commonwealth of Australia, residing at Fa rlles plantatlon, township of Woombye, 1n the State of Queensland, and continent of Australia, have invented a new and useful Instrument for Supplying Comminuted Giroldby Air-Fressure, of which the following is a specification.
My invention consists of a machine for filling teeth and crown and bridge building by driving particles of gold with great force by means of compressed an: into the prepared cavity of the tooth for filling or agalnst the prepared stump of the tooth for crown building or against the gold wlre for bridge building.
I attain the objects of my inventlon by the mechanism illustrated in the accompanying drawings, in which- I Figure 1 is a side elevatlon of the invention;
Fig. 2 is a longitudinal section thereof,
partly in elevation; I Fig. 3 is a transverse sectlon through the valve on line 33 of Fig. 2; and
Fig. 4 is a side elevation of an alternative form of nozzle.
Like numerals refer to like parts throughout the several views. 7 Referring to the accompanying drawings, I provide a handle 1 to which is attached a flexible tube 2 at 3 opening into air channel 4. The handle 1 is provided with a valve chamber 12, in which is slidably mounted a suitable valve 5 having an opening therethrough which may be moved into and out of registration with the channel 4. I provide a cylindrical chamber 6 into which channel 4 opens. I provide a paddle wheel? having a hub 8 mounted in the opposite sides or covers of the chamber 6. Chamber 6 has a mouth 9 to which any suitable nozzle such as member 10 or 19 is suitablIy attached, as at 11, as shown in Fig. 2. provide a bell crank 16 attached by pivot 17 to the valve 5 for operating said valve. The other end of the bell crank is pivotally attached to a trigger 14, which is mounted by means of pivot 15 in handle 1, as shown in Fig. 2. I also provide a suitable guard member 21 for the trigger 14.. Trigger 14 and valve 5 are normally held in retracted position, with the valve closing the air channel 4 to prevent the flow of compressed air Specification of Letters'latent. iPatented JAM S Mus I .also provide a suit abl'efia'dmission .nozzlef'and slotted rotatable cap 8f'fo Y the emovable oover. 20 of the cylindrical chamber 6.
To operate the device compressed air is admitted through flexible tube 2 and channel 4 in handle 1. The trigger 14 is pulled, thus lowering Valve 5 so that the opening in the valve will register with the air channel and allow the compressed air to flow into the chamber 6, thus rotating the paddle wheel 7 and causing the particles of gold or other metal in the chamber to be stirred up and driven through the mouth 9 and nozzle 10 into the cavity of the tooth, or against the prepared stump, or against the gold wire foundation, as may be required in the par ticular dental operation to be performed.
The chamber and nozzle of the instrument may be constructed of glass or any suitable material to which gold will not readily adhere.
What I claim is:
combination of a handle having an air channel extending therethrough, flexible means for admitting compressed air to said channel, a valve in the path of said channel, manually operable means for 1 opening the valve to allow air to flow therethrough, a cylindrical chamber into which the air channel'opens,
a rotatable paddle wheel mounted in said chamber, a mouth for the outflow of air charged with the particles of gold or other material used in dental work from said 1. In a dental surgical instrument, the
chamber, and a nozzle of the required shape attached to the aforesaid mouth.
2. In a dental surgical instrument of the class described, the combination of a handle member having an air channel therethrough,
a valve chamber in the path of the air channel, a valve slidably mounted in said chamber; a'bell crank attached to said valve, a trigger operatively attached to the bell crank, a spring normally holding the trigger and Valve in retracted position to close the air passage, a chamber for the particles of filling metal, into which said air channel opens, a paddle wheel rotatably mounted in said chamber, the chamber having a month,
and a nozzle attached to said mouth, sub- 7 Y stantially as described.
3. In combination with the apparatus described in claim 2, a removable cover plate for the chamber in which the paddle wheel is mounted, and a filling nozzle on said cover plate for the insertion of particles of the filling metals therethrough Without removing the cover plate, substantially as described. y, c
V 4. In a device'of the class described, the
combination of a curved handle having an air channel extending therethrough, a valve positioned in the path ofsaid' channel, mane:
ally operated means for opening the valve, said" means including a spring normally holding the valve in closed position, a short cylindrical chamber into which the'airchannel opens, a rotatable paddle Wheel in said chamber, a discharge nozzle with which said cylindrical chamber is in communication, the cylindrical chamber having a cap mounted .onhthe cover thereof for the admission of particles of metal used in dental WorkWithout removing the cover, and a guard member extending from thecylindrical chamber to the handle and protectingthe manually operated trigger means for controlling the valve above described j FREDER IC J MUSPRATT.
