ATTACHMENT FOR DENTAL MACHINES.

Specification of Letters Patent.

Patented Dec. 8, 1914:.

Application filed February 18, 1914. Serial N 819,539.

To all whom it may concern:

Be it'known that I, WILLIAM H. KING, a

citizen of the United States, residing at Blacksville, in the county of Monongalia and State of Vest Virginia, have invented certain new and useful 'Improvementsun Attachments for Dental Machines, of which the following is a specification, reference be- L ing had to the accompanying drawings.

This invention comprehends certaln new and useful improvements in attachments for dental machines, and has for its primary object to provide anattachment of this character which will serve to catch or recelve particles of gold and similar materials as the same drop from'fillingsduring opera-v tion of smoothing off and finishing the same, thereby preventing a waste of this valuable material.

Another object is to providev a device of this character into which the particles of material will fall, said particles finding their way to the retaining cup or receptacle which is detachably secured: to the lowermost ortion of a vessel.

A urther object is to provide a device of this character comprising a vessel having a retaining cup or receptacle secured "thereto and adapted to be secured beneath the instrument employed for smoothing-0E fillings, crowns, and bridge work.

A still further object is to provide a device of this character which Will be of such construction that it may beemployed in connection with the motor or grinding machine or with the lathe or any other machine employed in the dental profession.

This invention has for still another object to generally improve and simplify the construction of devices of this character and increase the efiiciency thereof, without increasing the cost of the 'same,'and provide means whereby the particles of gold and similar materials used for fillings, crowns, and bridge work, and heretofore lost when gginding down or finishing the work, may

saved, thereby effecting a. great saving to the dental profession.

With the above and other objects in view,

my invention consists in certain novel constructions, comblnations, and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the ac companying drawings,- in which,

Figure 1 is a side elevational view of one form of my device; Fig. 2 is a sectional rected portion 6 is the several views, 1 designates an open mouthed vessel, preferably bowl-shape in form,'wh1ch may be formed of rubber, aluminum, or other suitable material and which has one end lower than the opposite end with a depending neck or circular flange 2 adjacent the lowermost end, upon which is threaded the retaining cup or receptacle 3 for receiving or catching particles of gold and similar materials, a restricted opening 1 being provided in the lowermost portion of the vessel 1, whereby the filling material falling into the vessel may drop into the retaining cup or receptacle 3. The upper edges 5 of too vessel 1 are turned inwardlv, whereby any fillin'g material within the vessel will be prevented from falling out of the same, should said vessel be tilted. One side of the vessel is extended upwardly, adjacent the upper end of said vessel, as shown at 6, and said upwardly dirovided with 'a pair of spaced openings through which are engaged the screws 8 having the nuts' 9 upon their inner ends. also extended through the right angled end 10 of the supporting arm 11. The supporting arm 11 is curved transversely for engagement against the hand piece 12 of a dental engine, and is provided with a longitudinal slot 13 having the set screw 14 engaged therethrough and upon which is mounted the substantially U- shaped spring clamp 15 for longitudinal adjustment upon the supporting arm 11, the arms of said substantially U-shaped clamp being adapted for engagement upon opposite sides of the hand piece 12 of the dental en ine, the roarm employed in the form The screws 8 are dental engine, the operator grasps both the handcpiece 12 and the supporting arm 11 and may readily tilt the vessel 1 theproper direction to catch the particles of gold and the like which have heretofore been lost when filing down or smoothing fillings, crowns, and the like. It will also be evident that owing to the construction of the vesseland the manner in which it is removably engaged with the hand piece, said vessel will not interfere with the work of the dentist and all particles of the valuable materials u sed will drop through the restricted opening 4t to the retaining cup or receptacle 3.

When it is desired to employ this device in connection with the lathe used by dentists, the supporting arm 11 is disconnected from the vessel 1 and the free right angles fiattened portion 19 of the horizontal end 20 of the rod 21 is secured upon the screws 8.

The main portion of the rod 21 is rotatably and slidably mounted in the upstanding end 22 of the bracket arm 23 and adapted to be secured in adjusted vertical and horizontal positionby the set screw 24:, it beinglunderstood that the main or horizontal portionof the bracket arm 23 is flattened and provided with openings25 to receive suitable securing members 26 for securing the same to the work bench upon which I the lathe 27 is positioned, said bracket arm 23 being positioned so that the rod 21 may be properly adjusted to place the vessel 1 beneath the wheel 28 of said lathe 27-whenthe lathe is in operation or to swing the rod 21 to move the vessel 1 from beneath said wheel when not in use.

From the foregoing, it will be clearly apparent that I have provided a device of this character of extremely simple construction and operation as well as cheap to manufac ture, and which will be highly eficient in use and effect a saving of a quantity of valuable material employed by dentists for fillings, etc. I

' While I have shown the preferred embodiment of my invention, it will be understood that minor changes in the details of construction and arrangement of parts may be made withinthe scope of theappended claims, without departing from the spirit of my invention or sacrificing any of the advantages of the same.

ma am What is'elaimed is 1. A device of the class described Ed in-"- prising a vessel, a supporting arm detachably connected to'the vessel and adapted and means carried by said arm for detachablyand adjustably clamping the latter to the hand piece of a dental engine.

to overlie the hand piece of a dental engine,

2. A device of the class described comprising a vessel having a depending annular flange, a closure connected to said flange,

said vessel having an opening therein affording communication with said closure, and means carried by said vessel for support- 3. A-device of the class described comprising a'vessel having a depending flange, a

' receptacle connected to said flange, said vessel having an opening therein communicating with the interior of said receptacle, saidvessel having an outwardly extending arm secured to one side thereof, and means carried by said arm for detachably holding the vessel below the under face of a dental engme.., I Y n d. A device of the character described comprising a vessel, a supporting arm projecting from said vessel and provided with a longitudinal slot, means ad ustably mount- "ed upon said arm for clamping the latter to the'hand piece of a dental engine, means carried by the last mentioned means and engaged through the longitudinal "slot of the supporting arm for securing said clamping means in adjusted position longitudinally of the supporting arm, said vessel loeing provided with an open ended slot to receive the shank of atool carried by said hand piece, whereby the tool will be positioned above the vessel, and a retaining cup beneath said vessel.

5. A device of, the class described comprising a vessel having an upstanding wall at one side thereof, and means forv supporting such vessel below a dental abrading tool, such upstanding wall being provided with an open ended slot to accoodate the shanlr'of the tool.

In testimony whereof I hereunto afiiix my signature in the presence of two witnesses WILLIAM H. KING.
