CASTING-MACHINE.
Specification of Letters Patent.
Patented Sept. 5, 1916.
Application filed June 16, 1916. Serial No. 103,924.
To all whom, it may concern:
Be it known that I, STEPHEN P. ELLswonri-i, a citizen of the United States of America, and a resident of Richmond. Hill, Queens county, and State of New York, have invented certain new and useful Improvements in Casting-Machines, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
My invention relates to molds or machines for casting metals and has special reference to such as are adapted for making a large number of castings at one time from rela tively soft metal.
One object of my invention is to provide a machine of the aforesaid character that shall be particularly simple in construction and reliable in operation, and that shall embody a trough which is free from attachments and easy to manipulate.
Other objects and advantages of my in vention will be set forth hereinafter, and in order that my invention may be thor oughly understood I will now proceed to describe the same in the following specification, and then point out the novel features thereof in appended claims. p
Referring to the drawings: Figure 1 is a plan view of a casting machine arranged and constructed in accordance with my invention and constituting an embodiment thereof. Fig. 2 is a view corresponding to Fig. 1, with the trough removed. Fig. 3 is a longitudinal section, taken on the line 33 of Fig. 1. Fig. 4 is a transverse section, taken on the line of Fig. 1. Fig. 5 is a partially sectional end elevation showing the connections between the sections of the mold.
Like characters of reference designate corresponding parts in all the figures.
The machine comprises a rectangular frame 10 supported on a base 11, a trough 12 hinge-connected to the frame, and actuating mechanism to which the trough is adapted to respond when in its closed position.
The rectangular frame 10 has a bracket 13 secured to it at one end and a plurality of lugs 14 and 15 extending from its respective sides. The lugs 14 are on the back of the machine and are perforated to receive hinge pins 16 which, -in the arrangement shown, extend laterally from corresponding lugs 17 of the trough. The pins 16 are of sufficient length to permit a limited longiframe and are interconnected as clearly shown in Fig. 5, by links 20. One of thesections 18, which is adjacent to the hinge side of the frame, is secured to the frame by bolts 21 while the section at the opposite end of the group is operatively connected by a link 22 to an actuating lever 23. This lever is pivotally mounted at 24 on the lug 15 of the frame and carries near its outer end a bell crank latch 25 which is adapted to engage a hook projection 26 of I the frame when the sections are clamped together. A spring 27 presses the bell crank latch in position to engage the hook projection and is compressed when it is desired to release the latch.
Each of the connecting links 20 is affixed to one of the mold sections and is connected by a slot and pin connection to the adjacent sections on either side, the arrangement of parts being such that when the outer section is pulled away by actuating the lever 23, the sections are spread apart so that the completed castings will drop out.
The sections are provided with cooperating mold cavities 28 which are formed at the common top surface of the sections so that they open to receive molten metal supplied to them through the trough as hereinafter explained. The base 11 is provided with yielding strap brackets or supports 30 against which the trough rests when in its open position as shown in Fig. 4.
The trough has a handle projection 31 and a pair of hook-shaped projections 32 which are adapted to cooperatc with recesses 33 in the corresponding end of the frame, the parts being arranged so that when the trough is moved longitudinally the projections 32 engage the recesses 33 and clamp the trough upon the frame at one end. At the opposite end is the bracket 13 which is provided with a tapped hole 34 to receive an actuating screw- 35. The pitch of the threads is relatively high so that a considerable longitudinal movement of the screw results from turning the screw through a relatively small angle.
The inner end of the screw has a rela tively small neck 36 which extends over the body of the frame and terminates in a head or enlargement 37. The body of the bracket projects above the upper surface of the frame as clearly shown in Fig. 3 andhas a recess 38 through which the screw 35 eX- tends. An actuating lever 39 is affixed to the. screw in the recess .38 and is arranged to be convenientlygrasped by the hand of the operator.
The body of the bracket corresponds substantially to the trough in thickness and overhanging blocks orfingers 40 are secured to the-bracket and are adapted tohold the trough firmly against the frame in its-casting position.
Thecasting position is illustrated in Figs. 1, 3 and 5, and as clearly shown in Fig. 3, the trough 12 has an open recess 41 which is adapted tobeengaged by the head of the screw 35. Since'the recess 41 is open at the bottom the trough isfree to be lifted up by the handle 31 and swung back on its hinges as soon asreleased from the clamping projection-s 40 and 32.
The trough 12 comprises a plurality of longitudinal slots-42 each having a series of transverse gate openings 43 whichopen into the mold cavities 28 whenithe trough occupies its casting position.
The operation ofthe apparatus is as follows :-Assuming that the machine occupies its casting position asshown in Figs. 1, 3 and 5,.if molten metal such as lead, babbitt, or the like is poured into the longitudinal troughs &2, it will flow through the gates l3 into the mold cavities. Assoon as the cavities are filled and the metal set the lever 39 is actuated to turn the screw 35. This movement pushes the trough longitudinally until it is=released from the clamping proj ections and at the same time shears the ga-te ofi the castings. 'The trOugh is now freeto be "swung back on its'hin'ges by grasping the handle 31. Next the lever 23 is pulled-outwardly, the operator grasping'the bell crank latch 25 to release it 'fromthehooked projection 26. In response to this motion of the lever the mold segments arespread apart as shown in Fig. 2, permitting the mold castings which have been formed to drop out. A bin or receptacle (not shown) may be provided to catch the castings. The lever 23 is next pushed inwardly to close the sections, the trough swung down upon the frame, in which position the notch &1 cooperates with the head of the screw 35, and finally the lever 39 is again actuated but in a reverse direction to draw the trough into its casting position.
Attention is particularly directed to the fact that the trough is free from any attachments which would add to its weight or complicate its structure and consequently it can very readily be swung open and closed.
The blocks or fingers 40 are preferably provided with set screws 40 to adapt them accurately-to the thickness of the trough.
Various structural modifications may be effected within the spirit and scope of my invention, and Iintend that only such limitations be imposed as'are indicated in appended claims.
\Vhat I claim is:
1. A casting machine comprising a mold frame, a trough hinge-connected to the frame and having a notchedrecess, a bracket securedtothe frame, an actuating screw eX- tending through the bracket and having a head or enlargement adapted to cooperate with the notched recess ofthe trough when the trough is closed upon the frame, and means for actuating'the screw to adjust'the trough longitudinally-of the frame.
2. A-casting'machine comprising a mold frame, a trough hinge-connected thereto and adapted to slide longitudinally thereof .for a limited distance, a bracket secured to the frame atone end, an actuating screw mounted inthe bracket, operating in the plane of the trough and havinga head or enlargement, said trough being provided with an open recess adapted to cooperate with the head of the screw whenthe trough is closed upon the frame without interfering with the swinging of thetrough on itshinges.
In witness whereof, I have hereunto set my hand this 12th day of June, 1916.
