DIE-"SUPPORTING BLOCK AND SW-AGER.

Specification ofLjetters Patent.

Patented April 27', 1909.

Application riled July 81, 1907. Serial No. 386,410.

.To all whom it may concern: I

lie it knownthat I, .WILLIAM TfLYoN, re-

siding at Portland, in the county of Mult nomah and State. of Oregon, have invented certain new and useful Improvements in Die-Supporting Blocks and Swagers, of-

which t e following is a specification.

My'invention relates to certain new and useful improvements in'swagers, and par ticularly seeks to rovide an improved swager adapted to lie used in connection with the improved type of dental appliance disclosed in my co-pending application filed on even date herewith, Serial No. 386,409, and in its generic nature, the invention embodies an improved form of swaging mechanism hereinafter more fully described. In its more detail nature, the invention comprises certain novel details of construction, combination and arrangement of parts, all of which will be first fully described, then s ecifically ointed out in the appended claims, and i lustrated in the accompanying drawings, in which Figure 1, is a perspective view of the swager forming a part of my invention.

Fig. 2, is a similar view showing the parts thereof separated. Fig. 3, is a detail per spective view showing the manner of placing t e impression in position on the die supporting block and filling around the outer edge with a plastic material to prevent escape of molten metal. Fig. 4, is a similar View showing the method of casting the die by pouring the fusible metal into the heel of the im ression. Fig. 5, is a perspective viewthe die supporting block and die. Fig. 6, is aninverted perspective view of the die removed from the casting block. Fig. .7,- r

is a central, vertical longitudinal section of the device hereinafter specifically referred to.

Referring now to the accompanying drawings, in which likeletters' and numerals of reference indicate like parts in allof the figures, 1 designates the swager which is formed in three parts, consisting of the die supporting block 2, the ring" 3Qand the follower 4, as shown in Fig. 2 of the drawings, by reference to which it will be seen that the die f supporting block 2 has its upper face 2 pro The ring 3 fits snugly over the die supporting block 2, in practice, and the follower 4 fits within the ring 3, over thebloel; 2. Any improved means of holding the three parts of the swager together when in the position shown in Fig. 1, may he provided, as such means, per so, forms no part of my present invention; such holding means may be that shown in my co-pending application hercinbefore referred to, or the three sections may be clamped together in any approved manner.

In the practical application of my invention, the impression of the mouth is taken with plaster of paris on an impression tray, asin any ordinary operation, and after the excess of plaster is trimmed oh, the tray may be reversed and the plaster of paris impression held flatwise on the die supporting block over the depression 2 as shown in Fig. 3 of the drawing. After the impression has been placed against the die supporting block directly over the de ression therein, (see Fig. 3) the operator fil s around the outer edge of the impression with moldine or plaster 6, to prevent the escape of the molten metal which is to be ouredinto the impression, as hereinafter escribed.

The block 2 with the laster impression is thoroughly heated by p acing the same over a slow flame to prevent the metal from chilling too quickly, since the fine lines of the mouth are brought out much better, if this is done. After the die su porting block has been warmed, as stated, th poured into the impression through the heel thereof, as shown in Fig. 4. As soon as the metal has become sufiiciently cooled to become set the plaster impression is removed from the block leaving the metal die in position on the face of the die supporting block, ready for the next operation, it being understood that the molten metal has run into the depression 2 and become interlocked therewith. The metal plate 7 may then be placed over the die in the usual manner, after which, the ring 3 is laced over .the'die supporting block, and a .exible diaphragm 8 may be placed over the metal plate 7, and the die, and the plastic material 9 filled into the ring after which the follower 4 is pressed down into the ring to compress the plastic material therein, the follower 4 having a central aperture 4 to permit the insertion of a swaging plunger 10 which may be operated in any approved manner,

e molten metal is' either by hammer-in thereon, or by the use of the machine disc osed in my co-pending application hereinbefore referred to. The

parts are then in the position shown in Fig.

7, the block 2 may be removed from the ring 3 and the swaged plate removed from the die very readily. The die may be also removed from the block 2 by sliding it out of the depression 2 from the back toward the front thereof.

By constructing a swager having a casting block, as shown and described, the die may be readily removed from the block and other dies substituted or formed thereon without in any manner destroying the die so as to prevent its future use, whenever desired. This is a very great advantage of my invention and enables the dies to be re-used, a thing that is impossible with the ordinary type of die supporting block now in common use.

From the foregoing descriptiontaken in connection with the accompanying drawings, it is thought the complete construction, operation, advantages and use of my invention will be readily understood by those skilled in the art to which the invention ap pertains.

hat I claim is 1. In a swager, a die supporting block having a wedge-shaped depression in one face to receive a portion of the die to removably retain the same, the bottom surface of the depressed portion sloping from the bottom of the depression at one end to the top thereof at the other end, substantially as shown and 1 described.

2. In a swager, a die supporting block having a de )ression in one face to receive a portion of tie die to removably retain the (lie, the bottom surface of the depressed portion commencing at the top of the block at one end of the de ression and extending downwardly towar the other end, said blocl; having an undercut portion at such other end, substantially as shown and described.
