Specification of Letters Patent. Patented June 27, 1922.

Application filed January 12, 1922. Serial No. 523,713. l

ToaZZ whom t may concern:

B it `known that I, FRANK D. LEIPOLD, at Clearfield, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Amalgam Mixers, of which the following' is a specification.

lThis invention relates to certain new and useful improvements in' amalgam mixers, and the primary object of the invention is to provide a device of this type which can be easily and quickly attached to a dental en-v A gine so' as to be operated thereby and which is formed so as tol be held in and steadied by the hand of the dentist during the operation of mixing.

A further object `ofthe invention is to provide a device of this kind which is equipped with a sleeve or chuck that can be easily and quickly applied to the exible driving shaft of the engine and removed therefrom so as tothus enable the mixing to be effected expeditiously.

The invention stillfurther aims to provide a'mixer which is'positive and certain in y action and which is composedbial minimum l moval thereof.

0f parts of simple .an'd economical constructions that are compactly related so as to provide convenient storage when out of use.

The invention also aims to provide. a glass receptacle and means for sealing the inlet thereof during the mixing. operation and to also provide ,a holder fory the receptacle which will positively and firmly support the lattery and still permit of ready represent invention ay sleeve or chuck l is ernployed and which 'is preferably knurled or suitably roughened to afford a firm nger grip. The chuck has its inner end formed With slotted parts 2 and 3 for engagement with dental engines of varying types, some of which types fit part 2 and others part 3, the chuck being thus adapted for use with either type. A driving shaft 4 is suitably mounted in the chuck and is received by the usual chuck of the flexible shaft of the dental engine so as to be driven by the latter.

arm 5 is rigidly secured at one end to the'v chuck 1 and has an upwardly extending vthumb piece 6 on its opposite outer end. The shaft extends through the arm 5 and has a crank 7 rigidly secured thereto. Arranged in front of the thumb piece 6 is an upwardly extending post 8 to which a link` 9 is pivoted by means of a screw 10. The link 9 is slotted at 11 at itsouter end and slidably receives the crank pin of the crank 7, the latter having a screw`12 vsecured thereto so as to prevent movement of thelink from the crank pin.

The outer end of the link is formed with lateral arms affording a suitable support 13 for a receptacle-holder 14, the latter having

ends

15 and 16, the ends being provided with

circular rims

17 and 18 respectively. A suitable sealing'element such as cork, or rubber 19, or the like is frictionally or otherwise secured in therim 17, while a follower disk 20 tensioned by a coil spring 2lis lslidable in the rim 18. The holder 14 is open or cutaway along its sides and top, to enable a preferably glass receptacle 22 to be placed in and removed from the holder with its open end abutting and sealed by the element 19, while its closed end is engaged by the follower disk 20, which latter not only holds the receptacle in the holder but also exerts Constant tension thereon to maintain lthe open end thereof in sealing 'engagement with the sealing element 19.

By merely grasping the receptacle in the fingers, same may be moved against the tension of the follower'disk to bring the open end free of engagement `with the rim 17 whereupon the receptacle may be disengaged from the holder. In order to place the relies,

receptacle inthe holder, the closed end is impinged against the disk 20 and moved to force the disk inwardly against its spring until the open end of the receptacle is in register with the rim 17, whereupon release of the receptacle allows the tensioned disk to move the receptacle to the position of Figure 3.

In operation, the sleeve or chuck 1 is first moved or slid into engagement with the usual -chuck of the dental engine flexible haft, causing automatic. coupling oil the holder.

The receptacle is made of sufficient length so that the amalgam will be impacted with quite a little force both against the closed end of the receptacle and against the seal 19 to thus etlicientlvv imite the mercury and allov.V It will further be seen that the receptacle has oscillatorv movement in a curved line thus simulating shaking of the amalgam in a bottle held inthe hand of the dentist. The receptacle 'being formed of glass the'amalgam is visible to allow the dentist 'to observe the mixing/and to ,determine when same `is completed, without removing the receptacle from 'the holder. In Figure 5, a` modified form is illustrated;

The arm has a depending thumb grip 31 and is slotted at 32 to slidablyreceive a pivotal member 33, the latter being" secured to a holder '3l which latter Ialso is identicallwith the form of the invent-ion illustrated in Figures 1 to -L L A crank 35 is secured to the shaft of the chuckand is pivoted by member 3T to the a dental engine, an arm on the shaft ha-ving a thumb member to allow the device to be held by engaging the thumb with said' member and the fingers with said chuck, a holder, an amalgam receptacle carried by holder, means to pivot the holder to the arm,
