APPARATUS FOR MANUFACTURING FLYING TARGETS.
SPECIFICATION forming part of Letters Patent No. 328,570, dated October 20, I885.
Application filed May 12, 1885. Serial No. 165,193. (No model.)
T 0 all whom it may concern.-
Be it known that I, FREDRIOK O. DAMM, a citizen of the United States, residing in Peoria, county of Peoria, and State of Illinois, have invented certain new and useful Improve ments in Apparatus for Manufacturing Flying Targets, of which the following is a specification.
This invention relates to an improvement in apparatus for manufacturing flying targets, in which the pitcliy compound of which the targets are manufactured is maintained in a molten state, and flows therefrom directly to the mold.
The object of this invention is to combine the apparatus and mold in such a manner that the compound may be forced directly from the apparatus to and compressed in the mold while in a liquid state.
A further object is to regulate and separate from the main body of the liquid in the caldron or heating receptacle such an amount of the liquid compound that it may be effectively subjected to pressure and fill the mold.
A further object is to provide for a convenient manipulation of the mold and for controlling the flow of the compound thereto; and, finally, to provide a mold which shall not only produce a target of equal thickness throughout its surface, but which permits a direct pressure upon a portion of the contents in the caldron to be forced through outthe mold, which mold at the same time is so situated with reference to the supply-pipe of the caldron that it may be unlocked and the completed target be conveniently removed. I attain these objects by devices illustrated in the accompanying drawings, in which Figure 1 represents a vertical longitudinal section of an apparatus embodying my invention, with the mold partly in section; Fig. 2, a plan view of the mold, with full and dotted lines indicating the different positions to which the valve thereof may be shifted to close and open the mold; Fig. 3, a central vertical section through the mold; Fig. 4, a top plan view of a completed target; Fig. 5, a central transverse section through the same.
Similar letters of reference indicate the same parts in the several figures of the drawings.
The frame for supporting the caldron and In a cross-bar above the caldron is suspended a cylinder, B, which may be provided with flanges b for that purpose, and working in this cylinder is a piston, O, the rod 0 of which is connected by a link, d, with a lever, D, pivoted at one side of the frame, and provided on its other end with weight E, suitable notches being provided in said lever for the adjustment of the weight along its length to set it for any pressure that it is desired the piston shall have on the contents of the cylinder. A little above its center of length, but at any other suitable point, the cylinder is provided with an opening or passage adapted to be closed by a valve, e, countersunk in the inner side of the cylinder, so as to be flush therewith when closed, which Valve is hinged at its upper edge. By arranging the valve in this manner it is closed-by the descent of the piston, which is provided with an upright plate, E, flush with the edge of the piston, and adapted to maintain the valve in a closed position after the piston itself has passed it and until the piston is again elevated to the position shown in Fig. 1.
The valve-opening may be provided with a surrounding flange, f, projecting into the contents of the caldron or vat, and having a passage which at its free endmay be closed by a wire screen for the purpose of straining the liquid compound and preventing the entrance of any lumpy or foreign substance to the piston.
Opening into and near the lower end of the piston is a pipe, F, which, passing through the walls of the caldron,projects beyond the frame of the machine, and is bent downwardly and provided at its outer end with a slide-valve, G, for closing and opening said end when desired. The opening of the pipe F is in alignment with an opening, H, in a mold, I,which latter opening is closed by a pivoted platevalve, J, provided with a perforation, which valve,when swung upon its pivot,will open or close the opening to the mold, as the case may be, and in closing the same after the mold has been filled will smoothly cut off so much of the compound as may project beyond the top of the mold.
Mold I is composed of a lower part, g, on which the upper part, h, is removably supported, and the lower part or base 9 of this mold rests upon a table, K, below which projects a rod or bar, K, which works loosely in a bracket or standard, L, and is raised or lowered by means of a foot-lever, M, pivoted to the standard and to the rod, so that when in the position shown in Fig. 1, if the foot-lever be depressed, the mold will be elevated until its valve is forced more or less tightly against the valve of the supply-pipe F.
With this construction and arrangement, and assuming that the caldron is filled with liquid compound to a point above the valve-passage in the cylinder, it will be seen that if the piston is elevated by raising the free end of the lever D, the valve will be forced open by the contents, and asufficient portion of the contents of the caldron will flow into the cylinder to fill the same to a point not higherthan that of the piston. If, now, the foot-lever is depressed, and the mold raised in contact with the supply-pipe and the valves of said pipe and mold be opened, and at the same timethe piston be caused to descend, valves 6 will be closed and the contents of the piston, or so much of it as is necessary, will be forced into and fill under pressure the mold. As soon as the mold is filled, the "alve G is closed, the
mold lowered, and its valve manipulated to cutoff any excess of the compound projecting beyond the mold-opening, and either before or after-removing the mold to cool, the piston is elevated to again fill the cylinder if its contents be not sufficient to fill the second mold.
As shown, the chamber of the mold is of uniform diameter, but as the essential object of my invention is to uniformly force and compress the compound into the mold, which operation cannot be successfully effected without forcing it from some central point of the mold, it is obvious that the mold-chamber might be of somewhat irregular form without an essential departure from one of the important features of my invention.
When a single mold at a time is supported upon a table, K, it is proposed to employ a number of molds, so that as fast as one is filled and set aside a sufficient time to allow the material to set, another may be substituted, and so on; but instead of this arrangement the molds may be supported upon a carriage which can be moved along the entire length of the supply-pipe, and fill one at a time in the same manner, as above described, or they may be arranged upon a circular table surrounding the frame; but in any case it is preferred that each mold should be operated by an independent foot-lever to raise and lower it from the supply-pipe, because such an arrangement is found to afford convenience in the manipulation of the molds.
' In conclusion, it may be stated that instead of a lever for operating the piston, said piston may be operated by means of a small steamcylinder of ordinary construction mounted above the same.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1s
