Specification forming part of Letters Patent N 0. 180, [24, dated July 25, 1876 application filed May 5, 1876.

To all whom ct may concern:

Be it known that I, HERMAN GUELS, a resident of St. Louis, Missouri, have invented a new and useful Improvement in Machines for Making Oar-Seals, of which the following is 'a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which Figure l is a view of the invention, partly in vertical longitudinal section, and partly in side elevation; Fig. 2, a horizontal section taken on the line a: a of Fig. 1; Fig. 3, a plan proved machine for making car-seals. By

means of it also an im roved seal can be WO- duced. In its general construction it consists of a furnace where the metal of which the seal is formed is kept in a fluid condition, and from which it is drawn off into a mold beneath. The mold is contained in a slide which has a horizontal reciprocating movement, and after the seal has been cast it is carried in the slide to a suitable point, where it is ejected from the slide. The latter is then returned to its original position, and the operation is repeated. Suitable means are employed during the casting for forming the perforation in the seal, and for cooling the slide and surrounding parts.

Referring to the annexed drawing, A represents a reservoir or furnace, where the metal of which the seals are formed is held in a molten condition. The metal is previously melted elsewhere, but to keep it from chilling in the furnace the latter is surrounded by a fire-chamber, B. The furnace and fire-chamber rest upon a base, 0. A passage-Way, D, leads from the furnace downward through the base 0. There is a sub-base, E, which supports the entire structure, and in the following manner: At each end of the base E, and on its top, is a projection, e e; at each end of the part 0, and on its bottom, is a projection,

c c. The last-named projections rest upon the projections e c. In this way a space is provided between the part G and the sub-base E. In this space, F, a slide, G, is arranged to move, and as is hereinafter described. The slide is shorter than the space; but, in respect to its thickness, is made to fit snugly therein, and operating as a cut-ofl' at the lower end of the passage D to prevent the descent of the molten metal, saving as is hereinafter explained. H represents an opening in the slide,

and extending vertically through the same.

This opening is the mold wherein the seal is east. The slide is made to have a reciprocating movement in the space F. To effect this the slide is connected with a yoke, I, which in turn is moved in a reciprocating manner by means of a lever, J. The lever is pivoted at j to a projection, e, of the base, and is connected with the yoke at i. When the seal is cast the slide is arranged as in Fig." 1,-and so as to bring the opening H beneath the passage D. To remove the seal from, the mold the slide, by means of the lever, is moved, so as to bring the mold over an opening, K,in the base E. A plunger, L, is then caused to move downward, and to strike the seal down through the opening K. v

The mechanism for actuating the plunger is as follows: A stop, M, on the yoke I (in the movement of the latter) is caused to strike a lever, N arranged horizontally and pivoted at outer end 0 of the part 0 inward through and past the mold H, when the latter is in position to receive the metal. The outer end of the core is provided with a flange, q, to keep the core from being drawn in too far with the slide G in the movement of the latter,

and so that its inner end might interfere with the ejectment of the seal from the mold. The core, to ward its outer end,is further provided with another flange, q, to prevent the core frombeing thrusttoo far out from the machine by the return movement of the slide,

and so as to bring it into a position where it could not act a core when the second seal is made. The flanges are suitably spaced apart, and arranged to effect these ends, and in the movement of the core, they encounter, respectively. the outer and inner sides of the projections 15 e. The inner end of the core is forked. For an ordinary seal the core is so constructed and arranged as to extend the forksq g entirely across the mold during the casting, and, by means thereof, to form two perforations extending entirely through the seal.

To form my improved seal the core is constructed and arranged so as to bring a portion of the shank and the inner ends of the forks in the mold during the casting, and as shown in Figs. 1 and 2. The base E is preferably made hollow, as shown at E, Fig. 1, to enable the lower part of the device to be cooled by means of a water circulation therein.

The construction thus far described relates to but a single furnace and mold. I preferably employ a double construction. Accordingly, I make another furnace and fire-chamber, A and B, and arrange them similarly upon an extension of the part 0, and beyond the mechanism for ejecting the seals from the mold. There is a similar passage, D, leading downward, to convey the metal from the furnace A into a duplicate mold, H, in an extension of the slide G. The various parts are so proportioned and arranged as to enable the casting to be carried on alternately at either end of the machine; and while a seal is being cast in one of the molds H the seal previously cast in the mold H is being ejected from the lattcrthat is, the slide carries the seal formed in either mold to above the opening K, and beneath the plunger L. The ejecting mechanism is suitably duplicated. The molten metal is kept properly warm in the furnace by means of a fire in the chamber B, to which air is supplied through the apertures b b, &c. It thence flows into the mold H, where it surrounds the core, but is prevented from falling through the mold because of the base coming against the slide. The latter is then moved to carry the seal to beneath the plunger. There is danger, however, of the collapse of the top of the seal it the core is withdrawn too quickly. Therefore, and, preferably, by means of friction arising from the metal adhering slightly to the core, contrive to draw the latter along a little way with the .ration s, and out of the seal.

ration s the two perforations s s extend the remainder of the way through the seal. T represents the wire as a-ttached'to my seal. The two ends thereof are passed through the perforations s s, and then through the perfo- The ends are then twisted and the wire drawn back, bringing the twisted portion into the perforation s. The sides of the seal are then pressed inward, closing the entrance to the perforation s. The

wire cannot be drawn in the other direction because of the bridge 8 between the perfora. tions .9 s.

My machine can be enlarged in capacity by duplicating, in a lateral direction, the parts where the casting is donethat is, theslide can be enlarged and additional molds can be arranged side by side. A single furnace, however, can be used to supply allthe molds.

What I claim isl. The combination of the furnace A, part 0, having the passage I), base E, and slideGr, having the opening or mold H, substantially as described.

2. The combination of the part 0, base E, slide G, yoke I, and lever J, substantially as described.

3. The combination of the lever N, lever 0, part 0, and plunger L, substantially as described.

4.. The combination of the yoke I, stop M, levers N and 0, part 0, and plunger L, substantially as described.

5. The combination of theslide G and core Q, having the forks q q operating substantially as described.

6. The combination of the core Q, having the flanges q and q, projection c, and slide G, substantially as described.

7. The combination of the core Q, having the flanges q and q, forks q q, projection c, and slide G, having the mold H, substantially as described.
