4 Claims. (Cl. 259-75) This invention relates to a reciprocatory shaker for mixing small quantities of amalgams for use in filling teeth.
An object of the invention is to provide a reciprocatory shaker in the form of an attachment adapted to be applied to the arm of a dentists drilling unit having an endless belt for rotating the drills and which shaker includes a pivoted arm having a grooved wheel adapted to be swung into engagement with the belt for imparting reciprocatory movement to a removable receptacle for containing the amalgams for mixing the same and in which the pivotal arm together with the parts connected therewith are movable to an out-of-the-way position when not in use.
Still another object of the invention is to provide a reciprocatory shaker of said character having means for lengthening the stroke or reciprocatory movement of the shaker arm.
Still another object of the invention is to provide a reciprocatory shaker having a wheel for tensioning the belt against the driving wheel.
With the foregoing and other objects in view, reference is now made to the following specification and accompanying drawings in which the preferred embodiment of the invention is illustrated.
In the drawings:
Fig. 1 is a view in elevation of a reciprocatory shaker constructed in accordance with the invention and illustrating the same in operative position on the arm of a dentists drilling unit which is fragmentarily illustrated.
Fig. 2 is a vertical sectional view taken approximately on line 22 of Fig. 1.
Fig. 3 is a horizontal sectional view taken approximately on line 3-3 of Fig. 1.
Fig. 4 is a rear view of the reciprocatory shaker shown in operative position on the arm of a dentists drilling unit.-
Fig. 5 is a view similar to Fig. 1, with the operating parts moved to an out-of-the-way position.
Fig. 6 is a sectional view taken approximately on line 6-6 of Fig. 1.
Fig. 7 is a sectional view taken approximately on line 7-7 of Fig. 1.
Fig. 8 is a sectional view taken approximately on line 83 of Fig. 1.
Fig. 9 is a view in elevation of the receptacle for con taining the amalgams with the parts shown in separated juxtaposition.
Referring to the drawings by characters of reference, the shaker is in the form of an attachment adapted to be afiixed to the outwardly extending arm of a dentists drilling unit so as to dispose the attachment in convenient position for use by the dentist and which may be used to mix the amalgam required for the filling of one or more teeth while the dentist is engaged in drilling or treating the teeth. For this purpose, the shaker includes a flat bar 10 to which a clamping plate 11 is removably secured by screws 12 and which bar and plate have confronting recesses which together form substantially circular openings 14 for clampingly engaging the top and bottom bars B of the drilling unit. Tightening of the screws 12 effects a tightening of the plate 11 against the bar 10 to thereby secure the attachment to the said arm.
Pivoted to the upper end of the bar 10 on a pin 16 is an arm 17 having swinging movement from an out-ofthe-Way position above the bar 10 to a position in alignment therewith. The bar 10 is provided with a lug 18 which forms a stop for limiting the swinging movement of the arm and for retaining the same in the out-of-theway position. The arm 17 is spaced from the bar 10 by means of blocks 19 and 20 located adjacent the upper and lower ends thereof. The pin 16 pivoting the arm 17 to the bar 10 extends freely through the block 19 and is threadedly engaged at its outer end in the bar 10. The arm 17 is formed with a recess 21 which is adapted to receive the shank of a tightening screw 22 threadedly engaged in the block 20. Tightening of the screw 22 secures the arm 17 in fixed parallel relation with the bar 10 with a space therebetween intermediate the blocks 19 and 20.
Pivotally mounted on the outer end of the arm 17 on a pivot pin 23 is a shaker arm 24 having a member 25 afiixed to the outer free end thereof and which forms a socket for holding a receptacle 26. The receptacle 26 is adapted to contain a slug 27 providing a hammer or pestle 24 by means of a grooved wheel 29 mounted for rotation on a shaft 3% affixed to the arm 17 and which projects inwardly to dispose the grooved wheel 29 between the arm and the bar for free turning movement. The grooved wheel 29 is formed with a cylindrical eccentric hub 31 upon which is mounted a cam follower 32 having a cylindrical peripheral inner face 33 in engagement with the cylindrical face of the eccentric hub 31. The cam follower 32 is provided with a connecting link 34 which is adjustably secured at its free end to the shaker arm 24 by means of a clamping screw 35 having a shank 36 engaging through a slot 37 in the shaker arm and which clamping screw 35 is adapted to be adjusted toward and away from the pivot pin 23 and secured in adjusted position for varying the length of the stroke imparted to the outer end of the shaker arm by the rotation of the grooved Wheel. A peripherally grooved belt tightening wheel 39 is mounetd for free turning movement on a shaft 40 secured in an opening in a projection 41 formed integrally with and projecting laterally from the bar 10 to dispose the wheel in alignment with the grooved wheel 29. The tightening wheel 39 is relatively smaller than the grooved wheel 29 and is disposed in advance thereof.
The drilling unit is of the type having an endless belt C for rotating the shaft (not shown) in which the drills are inserted. The belt C has a driving lead D and a return lead E which travel in the direction of the arrows indicated in Figs. 1, 3, 4 and 5 of the drawings and are located on opposite sides of the bars B. The lead D of the belt C is trained over the upper peripheral portion of the tightening wheel 39 and thence under the grooved wheel 29, whereby the tightening wheel 37 in addition to taking up slack in the belt C so as to tension the lead D against the wheel 29, places a greater portion of the wheel 29 in engagement with the said lead.
The receptacle 26 is of cylindrical formation, as illustrated more particularly in Figs. 8 and 9 of the drawings, and includes a cap 42 which is frictionally fitted over the truncated upper end of the body thereof. The member 25 includes a cylindrical portion 43 afiixed to a spring strap 44 having an end 45 disposed in spaced relation from the cylindrical portion and which is adapted to receive the receptacle 26 with one end disposed in the cy- 3 lindrical portion 43 and the opposite end resiliently engaged against the end 45.
While the invention is illustrated in the drawings and described in the specification in connection with the preferred form thereof, it is to be understood that the same is not so limited and shall cover and include all modifications and forms thereof which fall within the scope of the invention.
