portion Sand foot port1on 1 are .in substan-U the block 1l. The block 11 is thus rigidly suspended from the underside of the head 8.

Removably mounted upon the bed-piece 4 is a self-contained ram actuating mechanism C of known construction which includes a body or casing 14 .within which is movable a ram 15 by means of gearing and a screw threaded rod. The gearing is actuated in known manner through a shaft 16 by a crank 17 so that upon rotation of the crank the ram 15 is moved inwardly and outwardly of the casing 14. For applying great power to the shaft I. 15

16, the crank may have a socket 18 to removably receive a rod-like lever handle 19. The mechanism C is set upon the bed-piece 4 with the ram 15 movable vertically, studs 20 being secured in the bed-piece 4 for preventing lateral movement of the mechanism C. :This

mechanism' is also formed with an integral handle 21 by which the mechanism may be strain rotative movement of the casing 14 I may secure to the bed-piece by` one of the bolts 5, an angle mlnber 22 having a notch 23 to receive the handle 21.

dentures, a pot 24 is utilized to receive a die 25 from which the denture is to be made. This die is in one operation arranged between a relatively hard rubber disk 26 and -a soft rubber disk 27, the sheet of metal 28 from which the denture is to be formed being laid upon the die. Another hard rubber disk 29 drical block 11. The ram actuatin is placed upon the soft rubber disk 27. In operation, the ram 15 is lowered so that the pot 24 may be set thereon beneath the cylinmechanism is then operated by the crank 1 to raise the pot toward .the block 11 so that the block enters the top of the pot into contact with the top rubber disk 29. Continued elevation of the ram then :exerts great pressure on the sheet of metal 28 within the pot so as to orce the plate'into snug contact -with the die to shape the plate.. Thereafter the ram actuating mechanism is operated to lower the ram, whereupon-the pot' is moved away vfrom the block 11 which remains suspended from thel head 8. The pot is then removed from the ram and the various parts within it lifted out.

With this construction it will be observed that the base A, frame B and ram and ram actuating mechanism C are se arate vunits which canbe easily and quic assembled into cooperative relation and is'assembled therefrom. The` parts are simple and relatively inexpensive in construction, butwat the same timeenable great pressures to be exerted between the ram and the block 11, for example Y {ifty tons. Also the base, frame and ram actuating mechanism are relatively small so that they can be easily handled and transported. The cylindrical block 11 being rigidly suspended from the head 8 does not require any manual manipulation accordin to the heretofore known methods, and said b ock is inserted in and removed from the pot by sim le actuation ofthe ram 15.

hile I have shown and Adescribed my invention as embodied in certain details of construction it should be understood that this is primarily for illustrating the principles of the invention and that the details of construction of the press may bemodied or changed by those skilledin the art without departing from the spirit or scope of the invention.

Having thus described my invention, what I claim is:

-1. A press for swaging dentures, comprising a base having a foot portion, an integral vertical standard and a horizontal top-piece, a frame including a bed-piece, a head and tierods connecting said head tosaid bed-piece,

.means for separably mounting said bed-piece tween said tie rods. Where the press 1s to be used for swaging,

2. A press for swaging dentures, compris- Ving a base having a foot portion, an integral vertical standard and a horizontal top-piece, a frame including a bed-piece, a head and tierods each having one end screw threaded into said bed-piece and at its other end a pairo'f nuts between which said head is clamped,

vmeans for separably mounting said bed-piece upon said top-piece, and a rain and ramfactuating unit removably mounted upon said bed-piece with said ram movable toward and from said-head, said unit being separate from said bed-piece and applicable thereto between said tie-rods. f

'3. In'dental swaging apparatus, the combination'of a pot to receive a die and associated parts, a press comprising a frame including a head having a block rigidly sus pended therefrom to freely enter said got, a base in opposed relation to said hea a ram on saidbas e in substantial axial alinement with said block to removably support said ot and move the same toward and from said lblock whereby said pot slips over said block or said block is caused to'enter said pot and exert pressure on the" dietherein, and means for actuatin said ram.
