P. L. HIGLEY, or CINCINNATI, OHIO.` Letters Patent No. 89,866, dated Ma/y 11, 1869.
IMPROVEMENT IN MACHINE ron MQULDING METAL DIsKs, RIvE'rs, am.
The Schedule referred tonv these Letters Patent and making part of the same.
To all whom it may concern Be it known that I, P. L. HIGLEY, of Cincinnati, in the countyofHarnilton, and State of Ohio, have invented a certain new and useful Improved Machine for Moulding Metal Disks, Rivets, Sto.; and I do hereby declare that thefollowing is a full, clear, and exact descrption of the construction and operation of thesarne,
lreference `being had to the annexed drawings, making part of this specication,in which- Figure 1 represents a perspective view of the devices for discharging the blanks Vfrom the mould.
Figure 2 is a perspective view of the top plate of the l machine, showing the troughs for pouring the metal.
Figure 3 is a perspective view of the lower part of the machine, the movable mould-plate, and the'mode of operating it.
Ihe devices shown in these igure's, when united in the direction of the 'dotted line by the bolts A, forml the entire machine.
My invention consists in a machine for moulding` metal disks for. seals, rivets, and other similar articles. B represents a bed-piece, to Vwhich the side pieces C C are secured.
Upon the side pieces is mounted a bed, D, having raised sides, E E, and provided with a slot extending down the middle, of a length sufficient to embrace all` In the form shown in the drawings, there y are two` such series of circular holes, so arranged, that when the mould-plate is thrown to one side of the bed, one series shall be overthe slot in the bed D, and the other directlyunder the series ofv openings in one of the troughs in the plate K. l
, When the plate G isthrown, by means ofthe cam, to the other side of the bed D, the series of holes `that was over the slot passes under the openings in the other trough of plate K, while the second series of holes, in plate G, comes over the slot, or opening in plate D. y f
The plate K isprovided, onits under side, with a steel plate, M, which forms the bottom of the troughs, and is perforated with holes, through which themelted metal passesinto the moulds in plate G.
Plates M and G being` iny contact, itis obvious that when the latter plate is moved under the former, by means of the cam, the eiect is to cut off the burr fromthe casting, and to leave a smooth surface.
For the purpose of casting seals for freight-cars, or similar purposes, a series of wires, O O O, isshown, extending from the side pieces E through theY moulds in the plate. G, and of such length, that when the plate G is thrownl from side to Vside, the wires upon. the opposite side will be withdrawn entirely from the mould, so as not to interfere with the discharge of the casting; but, as the casting may still adhere to the moulds, by the friction of the material, I have pro:
vided a series of punches, P P P, lig. 1, operated by the lever' R, and the double-inclined planes S and F.v
By moving the l'ever from sideV to side the punches are forced through the series of moulds over the slot in plate` l), thus discharging the castings from said moulds. Upon releasing the lever, the punches are raised by means of springs, one of which is shown at U, fig. l.
` The operation of this machine, the parts being bolted` together, as.heretoforefdescribed, is as follows:
Plate G being thrown to the. left of the machine, so as to be in contact with the side piece E, the melted metal is poured into the left-hand trough inthe plate K, and Hows through the holes in said trough into the moulds F F. As soon as it is set, by moving the lever I, theplate G moves to the other side of the bed D, the shearing-action of the plates G and M cutting olf the burr on the casting, while the movement of the plate G carries the castings themselves directly over the slot in the plate D. By a movement of the lever .R, the castings are discharged from the moulds, while the right-hand series of moulds, being now directly under the right-hand trough iu the plate K, is ready` for another casting.
It isobvious that the form of themould-sl may vary;
that the wires O O may be dispensed with, so that the moulds may be used for the casting of disks, or rivets, or any` other forms of the same general character.
Having thus described myinvention,
What I claim as new, and desire to 4secure by LettersPatent isl 1. The above-described machine for moulding metal disks, substantially as shown and described.
2. The movable plate G, perforated as described. 3. Ihe double series of wires O O, attached to the Astationarygplate at one end, penetrating the moulds,
serving as guides to the mould-plate, and acting as l cores for the holes, or slots -in the castings, substantially as shown. P. L. HIGLEY.
