Application filed December 12, 1908.

T 0 all whom it may concern:

Be it known that I ALBERT I. GOLDMAN,

a citizen of the United States of America, residing at Chillicothe in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Car-Couplers, of which the following is a specification.

My invention relates to certain new and useful improvements in car couplers and has for its obj ect the construction and combination of parts in form and substance to cause the draft to be thrown upon the main body parts of the car coupler and to relieve the pivot pin between the knuckle and the head from strain; to provide a perfectly closed head at the top to prevent the entrance of foreign substances; to provide a lock set for the coupler pin whereby it may be lodged and held without the operator being required to maintain hold upon the operating lever and to provide means for operating the coupler parts either from the side or top of thecar, and other details of novelty in combination which are hereinafter fully set forth.

That my invention may be more fully understood, reference is had to the accompanying drawings, in which Figure l is a front elevation of my coupling showing its connection with a car body; Fig. 1 is also a front elevation of my device showing a modified form of connection for operating the coupling parts. Fig. 2 is a top plan View shown in connection with the body of a car; Fig. 3 is a perspective view showing the knuckle and arm connection; Fig. 4: is a front elevation showing portions broken away and also showing in solid and dotted lines two positions of adjustment of parts of the coupler. Fig. 5 is a vertical section through the center of the coupler taken from the left hand side of the same; Fig. 6 is also a vertical sectional View taken from the right hand side of the coupler; Fig. 7 is a detail perspective view of an ear portion of the coupler head; Fig. 8 is a detail perspective View of the coupler pin or block; Fig. 9 is a detail perspective view of a bar designed to connect the coupler pin or block with the mechanism for shifting the block or pin; and, Fig. 10 is a detail perspective view of a modified form of lever designed for use in connection with the shifting parts of the Specification of Letters Patent.

coupler. Fig. 11 is a perspective view of the knuckle showing parts broken away.

In these drawings, A represents the draw bar provided with a coupler head A and is suitably recessed as shown, to receive certain working parts and within said recess are provided the shoulders a a, see Fig. 5, also one of the shoulders appearing in Fig. 4:.

The knuckle B is pivoted to ears projecting from the draw head as shown, by means of the pin B and is adapted to be forced open by an actuating spring when free to move, which said actuating spring B shown in Fig. 7 is coiled around the pivot pin B one end of the same being carried within a recess 13* and the other end carried within the slot B the arm of the spring which bears in slot B bearing somewhat above the face of the ear portion 13 of the upper head and is adapted to engage the recess B within the hub portion of the knuckle (such recessed portion bein shown in Fig. 1.1) so as to produce tension on the knuckle as it is closed. The knuckle proper is provided with the elongated portion C, being that portion below the curvature shown in Fig. 3 and is provided with the flange or lug projection C which flange or lug projection is provided as a stop to prevent the coacting corresponding parts from slipping past each other while coupled by reason of unevenness in the height of cars or irregularity in the road bed and also to prevent dropping out and falling upon the ground of the coupler. It will readily be seen that the coacting parts or couplers being secured together and locked, that if one of them should be pulled out from the body of the car it cannot slip out but rests upon the ledge C Integral with the knuckle is the arm D projecting substantially at rightangles with the face thereof and is provided with the shoulders as d, as shown in Fig. 3, there being a corresponding shoulder on the lower face of the arm in identically the same relative location. This arm as will be understood, is adapted to extend within the cavity in the draw head and when the knuckle is closed, the shoulders d on the said arm will engage the shoulders or, in the draw head and the. said shoulder engagements will sustain the draft or pull between the cars thereby relieving the pin from strain.

To lock the knuckle in closed position, I

have providedjthe block or pin E which, is

housed in the casing E as best shown in I or pocket for the purpose of alternately re-,

leasing or engaging the arm D of the knuckle.

F is a bar adapted to be carried within the channel F formed in the body of the draw head. The channel may be best seen by reference to Fig.6. The bar is provided with the finger projection F which is adapted to engage Wlth the opening E in block The lower end of the bar depends from an opening in the bottom of the draw head and is suitably pivoted to the arm G, which arm is also pivoted to' the draw head as at I. The direct connection between the bar F and the arm G is by the arcuate slot J which facilitates the coaction of the two arms so that as arm G is raised into the position shown in dotted lines by the operator drawing outwardly upon the rodK, the bar F will be elevated into the position shown in dotted lines carrying with it the block E and in such movement the connecting pin 9 between the two arms will move rearwardly in the slot,

In the operation of the parts, it is desired that when the locking block is raised, to disen age the arm D of the knuckle, that it may be sustained in such elevated position without the operator being required to maintain his hold upon'the rod K or other means that may be provided to manipulate the parts referred to. v

To accomplish the above specified object, the bar F is provided with the laterally extending shoulder 7 which is channeled out as at m and there is also provided the tapered projection n at the forward end of the shoulder inclining rearwardly to the lower:

portion of the channel, also there is provided the notch z in the barjust above the lug f which is of sufiicient size to embrace the lower wall A of the draw head. By the 1 formation of the bar as above specified, as; the bar is elevated and as it approaches the 1 maximum limit of such elevation, the rounded portionor elbow e will engage the tapered projection n at its maximum forward part and as the elbow passes upwardly and to the bottom of the channel N, the

bar F will be forced forwardly so as to of advantage.

head, which permits suflicient thereby unlocking the couplers so that cars, I

coupler in the same opened condition by.

contact, will cause the arm D to be pushed rearwardly and in being so pushed rearwardly, the forward end VD thereof will, on account of the relative arrangement of the arm D with the bar F strike the inner face of said reach, pushing it rearwardly a sufficient distance for it to clear the edge of wall A of the draw head, this disengagement of the said bar from the lock set position being accomplished just as the arm 'D has reached the point in its movement into the recess within the drawrhead that accomplishes the'proper engagement of the coacting knuckles for the proper coupling of the parts together and just at this point-{the locking block E will by force of gravity drop downwardly and in front of the face D of the arm D, thereby locking the parts together. 7

I close the top of the draw head com pletely to prevent foreign substances from becoming lodged within the coupler head which, if permitted to do so, wouldrdestroy the efficiency'of'the coupler. By means of forming the coupler head in themanner herein shown and free from all upward projections from the upper face of the head, I am able to use. this coupler in connection with passengercoaches, which is a feature "In connection withFigl l, I have shown a modified form of connection for operating the locking block, the same being shown in dotted lines and consists of a lever M shown in Fig-1O which is pivotedto the draw head as at O and also to the bar F as at Sand-the chain is provided for operating the'same. An elongated slot V is provided in lever M at its pivotal connection with the draw lay to enable'the bar to be shifted to and rawn from its proper lock set position. In theme of this character of connection for shifting the locking block, it is designed to be-applied where it is desirable to operate the coupler to be locked and unlocked from a point above the same, as for instance, where the coupling connection must lead to a switch engine or to the top of a car;

It is obvious that my invention may be embodied in different form from that shown herein, without departing from the spirit of my invention.
