This invention relates to acombined "pestle and dispensing means therefor.
"Here before it has 1: en 'comrn-on practice to provide amalgamo-enta lings'i'iy placin'g -a-snitable amount of'all-oy- ,l'l'lOItal and th'en add a quantity of mercery to the mortal enamel-gamation with the alloy in which the amalgamating-process was accelerated-p 1*the'use o apostle in-triturating-and mixing the materials.
' I have found that -'I canproceefi more *erpeclitiou'slyand* accurately by providing' a' reservoir for mercury wi'thin thharidlefif til-apostle.
It isan object or my invention to "provide a reservoir in the emale of a pestle including a valve oontrolledo-ispen'sing and measuring means to feed a quantityof' mercury flownover the elite of the pestle body into-the mortarand npon the alloy or metallic-mix avithin the mortar.
It is "an object-of my invention to provide pestle hanole with '--a removable capcomprising a flanged ring in combinationwvith-a stretchable diaphragm which "togethenmay-serve as a base for the*appariztuswvherby the apparatus stood an inverted upright'positionion-a "substantially horizontal support-when not in use.
It isan object of-this-inventionto provide an elastic flexible --diaphragm 'attacha'bly "and "detacha-bly secured-on the enclof the pestle handle by a fianged'ring.
It is -an-object of thisiinvention totprovide an attachable and detachable pestle body for the handle whereby 'anold worn-ont pe'stle"booy'may be replaced by a new one.
Titis an object of i this invention to provide a valve body that is springactuated 'to olose'd'gpo'sition by a spring 'andmanually .a'tcthaitedto an open position by"fin'ger=pressurei(m "a resilient flexible diaphragm.

"The fplastichandle may be made of molded phenolic "plastics, methyl methacrylate ,plasties, vinyl resin plastics, polystyrene plastics, acrylic resins, cellulose acetate, ethyl celliilosaetc.
The hanole- 2' isprovfded vvitha'cor'nbi-ned valve seat and valvwstemjguide "5. "The handle '2Iis provided with an"exten"sion 6"10'e'y0'n'cl the valve seat and receives one end 'of'apestlebody 7 which i'scleitaeha-blyse'cnreol hereinby any soft-able s61- iible iue li. The pestle mew 'i's'provi'ded with an inc lecl end *9 '--located with iifthe "extension 6. The extension t is-provided with an exit orifice" I'll unseat the lowest'portion of the inclineiiefid9.

Theivalveste-m l l -is also provid'clwith arecluced portion its conneoting *the *valve head with 'the remaindermf *the walve stem I. This reduced portion [3 forms a passageway from the reservoir 3' tofz'the compartment M. The upperend of "the valvestem l l is provided ith a-'remova-ble'-knob pretenaiblyi-serew threaded to 'the endofth'estem I l and. located substantially flush 'Wit-h the upper end ot the reservoir- 3;

Thezvalvezstem 1S sorrounded by ahelioalcom- ;pressionispringg mipreterably made'ofcatbon steel or any suitable material that will not amalgamate with the mercury.
The valve stem II and the valve head I2 and the knob I5 may be made of substantially pure iron or any suitable material such as plastic material that will not amalgamate with the mercury.
If the valve stem II, the knob I5 and valve head I2 are made from a suitable plastic material, such as specified for making the hollow handle, then the plastic material for said valve stem etc. need not be made of transparent or translucent material.
The pestle body I may be made of porcelain or any suitable plastic material. The exit orifice III is formed in the connection or joint of the tubular extension 6 with the pestle I. The exit orifice I leads from a position above and at the lowermost portion of the incline or ramp 9 to the outer surface portion of the pestle I, so that the mercury can roll down or descend on the pestle into the mortar I9 without excessive splashing.
The mortar I9 is conventional and forms no part of my invention but is disclosed merely to visualize clearly the use and operation of my combined pestle and dispensing device or apparatus.
When the manufactured parts are ready for assembly the valve stem I I is inserted through the valve seat and guide and the spring I8 is placed in position surrounding the stem I I.
The spring I8 is depressed so that the knob I5 may be applied to the valve stem II to maintain the spring under tension. Now the stretchable diaphragm I6, which is preferably made of rubber, is placed over the end of the tubular hollow handle and secured in position thereon by the screw threaded flanged ring II. The pestle body I is detachably secured in place by a soluble cement or glue so that an old Worn-out pestle body may be removed by dissolving the glue in water or other appropriate solvent.
In operation the apparatus comprising the pestle is used in the ordinary way in connection with a mortar containing the dental filling alloy or mix. When it is desired to dispense a charge of mercury the valve is depressed by a finger tip of the operator as indicated in Fig. 2. If the release of a charge of mercury is not sufficient to make the amalgam of proper consistency a further charge may be added by repeating the operation of depressing the valve against the tension of the spring. If more than a measured charge is desired the pestle may be operated as indicated in Fig. 3. If it is desired to empty the reservoir 3 the valve may be maintained in an open position as clearly indicated in Fig. 3.
In Fig. 2 it is to be noted that the valve stem I I exactly fits the valve seat outlet and cuts off the exit of mercury 4 from the reservoir 3 so that the stem II serves as a sliding cut-off valvewhereas the valve head I2 operates as or similar to a poppet valve of an internal combustion engine.
It is also to be noted that the inclined end 9 of the pestle body I serves as a stop to prevent excessive range of movement of the diaphragm I6 as shown in Fig. 2.
When it is desired to place the pestle in an out of use position it may be inverted and supported in that position on a substantially horizontal support thereby using the ring H as a base.
While I have described my pestle as being particularly useful in connection with the dispensing of mercury over a pestle body it appears to bev self evident that it could be used for dispensing other liquids as well as powdered material.
Having fully disclosed my said invention what I claim is:
1.
