AMALGALEATOR ATTACHMENT.
Our invention has forits object to provide an extremely simple and highly efficient amalgamator attachment for the hand piece of a dental engine for use in mixing alloy and mercury into an amalgam for an amalgam filling and for any other purpose that amalgam is used in dentistry. Said.amalgamator is provided with means by which it may be readily attached and detached from such a 19 hand piece and is provided with a shank to beheld by the chuck in said handle and operated by the driven shaft to which said chuck is applied.
To the above end, the invention consists of 1 the novel devices and combinations of devices hereinafter described and defined in the claims.
In the accompanying drawings, which illustrate the invention, likecharacters inclicate like parts throughout the several views.
Referring to the drawings:
Fig. 1 is a side view of a hand piece of a dental engine having the amalgamator attachment applied thereto;
Fig. 2 is a View corresponding to Fig. 1, principally in central longitudinal section;
Fig. 3 is a front elevation of the invention, with some parts broken away;
F 4 is a detail view with some parts secti oned on the line 4c4: of Fig. 1;
Fig. 5 is a perspective view of the capsule l Fig. 6 is a view corresponding to Fig. 4 but showing an inner capsule in the outer capsule; and
Fig. 7 is a perspective view of the inner capsule.
The numeral 8 indicates the hand piece of a dental engine, not shown, carried by the customary swinging arm 9. Journaled in the hand piece 8 is a tubular shaft 10 having on. its rear projecting end a grooved. pulley 11 over which runs a belt, not shown, for driving said shaft from the dental engine. Carricd on the front end of the shaft 10, within the hand. piece 8, is a normally set chuck 12 for holding the shanks or spindles of the in terchangeable tools such as drills, grinders and the like, removably mounted in an axial seat in the front end of the hand piece 8. A thumb-actuated plunger 13 for releasing the chuck 12 extends axially into the shaft 10 from the rear end thereof. The parts thus far described are of standard and well known construction.
Referring now in detail to the. amalgamator attachment, the numeral '14 indicates a cylindrical oody memberaxially aligned with the liand piece 8 and having at its inner end an axially extended socket 15 into which is snugly telescop-ed the front end port-ionof the hand piece 8. A notch 16 in the socket end of the hand piece 8 is arranged to receive a radially extended set screw 17 in said hand piece to hold the body member 14 against axial turning movement on said hand piece. On the under side of the body member l l is a depending handle 18 by which the amalgamator attachment may be held.
An upright arm 19 is intermediately pivoted at 20 to one of the upright memb-ersof a U-shaped bracket 21 rigidly secured to the body member 14: by having its other upright member rigidly secured to the under side thereof. This bracket 21 supports the arm 19 axially spaced from the front end of the body member 1 1 for swinging movement transversely thereof and with its lower end substantially at the axis of said body member. On the lower or short end of the arm 19 is a laterally projecting cam pin 22 that extends into an endless cam channel 23 formed in the front face of a rotor 24; at the front end of the body member 14 for rotation about the axis thereof. This rotor 24 is provided with a spindle 25 to which it is secured by a set screw 26. Said spindle 25 is journaled in the body member 14 with its inner end portion extending axially through the socket 15 and is held against axial movement in said body member by the rotor 24 and a collar 27 in said socket. The inner end portion of the spindle 25 extends axially into the tool seat in the front end portion of the hand piece 8 and is detachably secured to the shaft 10 for rotation therewith by the chuck 12.
On the upper end of the arm 19 is a capsule 28 which extends transversely of the body member 14. The body of the capsule 28 is permanently secured to the arm 19 and its cup 29 is provided with a bayonet slot 30 arranged to receive the arm 19 and thereby detachably secure said cup to the body of the capsule. The cam channel 23 is so formed as to cause the arm 19 to stand still during part of the rotation of the rotor 24 and then swing said arm with a hammer-like action first in one direction and then in a reverse direction during the balance of the rotation of said rotor. An alloy 00 and mercury :2
is shown in the capsule 28 in Fig. 4: to be mixed by the amalgamator.
The swinging movement imparted to the arm 19 by the rotor 24 is highly important in its action in that it throws the compound to be mixed first to one end of the capsule and then to the other with a hammer-like action and thereby thoroughly mixes the same. lVhen the compound is thoroughly mixed the attachment may be readily detached from the hand piece 8 and the compound emptied from the capsule 28.
In some instances it might be desirable to mix the compound in a separate capsule 31 removably mounted in the capsule 28, as shown in Figs. 6 and 7.
lVhat we claim is:
1. An amalgamator attachment-forthehand piece of a dental engine comurising a body member applicable to said hand piece, an arm intermediately pivoted to the body memher, a capsule rigidly secured. to the long end of the arm and having a displaceable cup, and a rotor operative on the short end of the arm for imparting long quick intermittent oscillatory movements thereto, said rotor being arranged to be operated by the driven chuck of such a hand piece for rotation there with.
2. A dental amalgamator including a shakable arm, and a capsule, the body of the capsule being secured to the arm, the cup of the capsule being provided with a bayonet slot into which the arm extends for detachably holding the cup on the body of the capsule.
3. An amalgamator attachment for the hand-piece of a dental engine comprising a body member having at one end a socket, a spindle journaled in the body member and extending into said socket, a rotor on the spindle, a capsule-equipped arm pivoted to the body member and connected to the rotor to be operated thereby, the socketed end of the body member being adapted to be telescoped onto the outer end of said handpiece with said spindle secured in the chuck thereof, and a lock element on the body member for securing the same to the hand-piece to hold the same from turning in respect thereto.
In testimony whereof we aifix our signatures.
