uring materials for tooth fillings, and has for its object to provide a new and improved device of this description. In forming amalgam fillings, for example, from powdered metal and mercury, it is essential to secure a filling of the proper lastingqualities,'to mix powdered metal and mercury in certain definite-proportions; It is usual among dentists at the present time to guess at the amount at the time the filling is made. This method is'objection'able, as. it 'is practically imposslble -to secure the proper proportions in this manner. one of the objects of'my invention is'to provide a device by means of which the proper pro-.
portions of powdered metal and'mercury may be easily and quickly obtained at the time the filling is being inserted, and by means of which the proper amounts may be easily provided'without waste of material.
The invention is illustrated in the accompanying drawings, wherein Figure 1 is a view showing. one form of device embodying theinvention;
Fig. 2 is a sectional view taken on line Fig. 3 is an enlarged longitudinal lsectional view of a portionof-one of the rota-o table parts. 7

"In carrying out my"invention,I1'provide a body portion 1, of any suitable material such, for example, as glass, hard rubber or the like. This body portion, is preferably integral and .is provided "with two receptacles 2 and .3. The receptacle2is for the S peeificati onof Letters Patent.

dered material- These receptacles are pro-'- vided with covers 4 and 5, which are prefer ably screw-threaded, the upper ends of the receptacles being screw-threaded to receive Below the receptacles 2 andl3" the covers. are the rotatable parts-6. and 7, which eX v tendthrough'holes 8 and 9' in the body portion 1, said holes communicating with the receptacles 2 and 3. The rotatable parts 6 and? are provided with one or more measuring openings or pockets 10, which are adapted to receive a portion of themat erial 1n the receptacles 2 and '3 when opposite'isaid receptacles, and to discharge said material through the discharge openings 11' in the bottom of the body portion 1 whenthe rotatable parts are rotated so that the measur ing openings are opposite the "discharge openings. These'roratablefparts may each be provided with one pocket orla' plurality of pockets. The powdered material inthe receptacle 3 is liable to pack, so thatvit will not freely pass into the measuring o'pening or pocket 10, and some means provided for preventing this packing "and insuring the passage of equal amountsint'o these measuring openings when the device isLbeing used 'Asherein shown,'I 'provide' an agitating piece or disk 12, adapted to tbe The bottom of this receptacleis preferably disk 12 is. also beveled, andits "diameter? is shorter than the diameterof the receptacle,'
so that itmay be freely movedback and forth across the receptacle above the dislocated at the bottom of the receptacle 3."-
charge opening through which the powf';
dered material passes into the measuring opening 10. The agitating piece'12 is pref erably providedwith' a plurality of openings 14 and'a centrally located opening 15. An agitating spring 16 passes through one of the openings in the part-12, preferably the opening 15, the spring preferably pro jecting through the part12so'th at its end: projects beyond the wall of the. opening9 and a short way into one of themeasuring openings 10; When the rotating part 7 is rotated, thespring 16fwillengage the side of the measuring opening 10"a1id be moved.
to one side," carrying. the "agitating part 12 I with it,and. as the rotatable part 9 is .fur-' ther rotated will be suddenly released and spring back, carrying the agitating. piece 12 backwithx It will thus be seen that the f agitating part 12 is thus given a rapid movement, thereby agitating the powdered material at each mov'ement ofthe' part so as torprevent packing thereof and so to insure the proper amount of powdered material being discharged into the measuring opening 10. j The spring 16' is preferably held to one side by engagement with I the portion of the rotatable part 7 between the openings or pockets 10 while the rotatable part-7 is beingrotated, until the next measuring opening comes beneath the re 7 ceptacle, whereupon the spring is released 1s receiving'such material.
and it then flies back, thus agitating the material justv when the measuring opening In view of the fact-that the agitating piece 12 must be at the bottom ofthe receptacle, it willbe seen thatfit and the, spring 16 must be in position before the powder is inserted, and that these parts must not bedisturbed by removing the cover 4 tojinsert the powder. In the V w construction herein'shown the spring 16 is V provrdedat the top' wlth an engaglng part 17, which engages the'wall of the receptacle.
' I prefer to form the agitating spring 16 of "a spring wire and to: form'the'engaging part 17, integral with it by bending this wire so as to form the .piece 18. The engaging part 17 may 'be formed by'a loop produced by V bending the-wire as shown in "Figs. 2 and be located near the middle of the receptacle.-
4. The piece 18 permits the spring 16 to I also prefer to provide a groove 19, the engaging part1? being within this groove so that it wil'l be held against downward movement. It will thus be seen that, the cover 1 maybe removed without disturbing the spring and agitating piece 12, and that said cover, when placed in position, will prevent .the'upward'movement of the engaging part '7 117 andihence the spring 16. I prefer to drawn from the body-portion 1.
which spring back to. their original positions when bent, said spring pieces being '-removahly fastened in position by means of'faSteningdeVices 21. The size of the 'measu'ring openings 10 maybe permanent, as shownin Fig. 7, or they maybe adjust able -softhat varying amounts of material 7 may be, measured and discharged thereby 1 As shown in'Fig. 3, these .measurin'gopen- 'ings are provided with adjustable bottoms 22, said adjustable-bottoms having screw 5 threads which engage screw' threads in. the openings. or pockets 10. j The adjustable bottoms are preferably provided with means by whrchthey'may be rotated to vary their posit on in the openings or pockets 10; in
orderrto vary the amount of material contained in such pockets, As herein. shown, these adjustable bottoms are provided with grooves 28. for a suitable instrument such as a screwdriver, sothat they may be rotated to move them in or out to'vary the size of the openings or pockets 1 0.
, -In the-specification and claims I have used the -word groove to indlcate' the ing adapted'to communicate with the re ceptacle when therotatable part isfin a pre determined position, an agitating piece in the bottom of said receptacle, adapted to be moved back and forth there-across,an agi tating spring projecting through said ,agi-. tating piece, the end thereof engaged by said rotatable part, the upper end of said spring bent into the form of a-loop engage ing the wall of said receptacle soras to be held in place. a
