To all whom it may concern.-

Be it known that I, LEoroLD BoTrEN- STEIN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Car-Couplings, of which the following is a specification,

reference being had therein to the accom 1 panymg drawings, forming part of the speclfication, in which A Figure 1 is a longitudinal vertical sectional view of my improved coupler on the line I. Iof Fig. 2. Fig. 2 is a plan view of the apparatus, showing it in relation to the cari'rame. Fig. 3 is a sectional detail view of the draw-head, showing the locking-pin raised. Fig. 4 is an end view showing my improved buil'ers and signal incorporated with the apparatus. Fig. 5 is a detail view, in side elevation, illustrating the mounting of the bufl'erframe. Fig. 6 is a horizontal sectional vlew of the drawhead, showing the jaw in coup- 1 ling position- Fig. 7 is a similar view showing the aw extended in position for coupling.

My invention refers to improvements in car-couplcrs and it has for its objects to provide a simple, reliable, automatic coupling which may be coupled with "another similar one or with the ordinary coupling-link and is as to the coupling-head oi the type known as the Janney coupler.

The invention also provides for the incorporation with the draw-head of draft connections combined with laterally-arrangcd buffers, also a hiding and head ejecting spring incorporated with the draw-head, to- 'gether with the improved mechanism for operating the jaw and for providing for free lateral movement of the draw-head in rounding curves, together with various other details of may hear" at one side or the other.

improvement and construction, as shall be more fully hereinafter set forth.

The device is so constructed as to insure certainty of operation and prevent accidental uncoupling, while meeting the various conditions' and requirements usual with this class of apparatus. It is entirely automatic in its action and designed to avoid all danger of accident or injury, while materially reducing the shock incident to the coupling of the cars.

Referring to the drawings, :2 is the draw head, connected at its back portion with a. tongue or strap 3, secured centrally of the usual body-bolster 4 midway between the wheels of the truck, and so arranged to per- 11111; of lateral movement of the draw-head and tongue to the right or left, as indicated in Fig. The draw-head is supported by a cross-bar 5, extending across umlerneath the car-body, upon which the draw-head rests by means of an upward and backward L-shaped bracket 6 or other suitable support. Similar .lateral extending supporting-bars 7 7, curved to the radius described by the drawhead, extend across underneath the car at its front portion, being secured in the butl'erblocks, which are slidingly mounted in the frames 8 S at each side. These curved supporting-bars pass through the upper and lower portion of the draw-head or engage supporting slotted portions thereof, as shown in Fig. 1, sullicient clearance being provided to permit of free movement to the right or left, as will be readily understood. The draw-head is also further supported by means of a bracket 9, secured underneath the bolster 4, as shown, extending forwardly and pro-- 'vided with a widened bearing-shoe 10, having terminal ilanges l1 1]. with cushion springs 12 12, against which the draw-heml I By these means the draw-head is well supported and also maintained in ap n'ox'imate alinemene with the center oi therar, being still capable of sullicient lateral n'iovement .to provide for the various positions assumed-in coupling.

13 is the coupling'j aw, pivoted in the drawhead at 14 and. provided with anopening 15, into which the coupling-pin 16 enters do\\'n wardly, so as to securely hold the jaw in closed position. The/pin 16 may be raised in any suitable manner; but I )reler teem ploythemnstruetion shown in l igs. 1,2. and 3, m which the upper portion oi lhe pm is provided with rack-toot l 17, engaged by the ITO '. wherein the spring 25 and bolt extension 26 are mounted to one side of the center, thus dr tw-head, the.lever I9 engaging by a ter- '22 is preferably made in one piece, as shown a foot-openin -g'ate or door 24, w ich may even with the floor.

The wrist-pin 21 is also 'curve segment-teeth 18 of a lever 19, pivoted at 20 in a bracket extending upwardly from the minal slot an elongated wrist-pin 21 of ac-' ,like bars 7, to correspond with the radial movement of the draw-head, and crank in F1g, 2, having suitable bearings in the 'buffenframes 8. This operating-lever is actuated by a foot-lever 23, extending back- .Wardly beneath the platform and in register covered by a hinged be laid down lever the back end of lever 19 will be epressed, lifting'coupling-pin 16 to allow for'outward opening of the jaw employ a spring 25, which in the closed position of the jaw is under tension and bears forwardly against a terminal bolt 26, having a lip 27 engaging a corresponding slot in the bac (portion of the coupling-jaw, the bolt 26 bein guided in longitudinal alinement with the raw-head. By this construction when the pin 16 is raised the coupling-j aw will be 1 Shown in Fi show a modified construction In' Fig. 11

increasing the leverage. The coupling-pin 26 when not in registerwith the hole 15 0r dinarily rests upon the top of bolt 26 or' upon a backward shelf-like extension 13 of the coupling-jaw, as shown in Fig. 9. The couplin aw is also provided with a supplemental loc ing-shoulder 28, adapted to engage a corresponding shoulder 29 in the draw-head, against which it will bear and perform its functions if for any reason pin 14 should become broken or displaced, thereby preventing accidental pulling out of the couplingj aw in such emergency. It will be seen also that the draw-head is recessed or open, as at 30 thus providing suflicient clearance for the shoulder 28, which may be of any suitable size and which will be flush with the outer surface of the draw-head. Pivoted at 31 in the upper end of a suitable frame, consisting 'princlpally of a hollow pipe-support 32, is a semaphore-signal 33, having a short crankarm 34, attached by a connecting chain or cable 35 to a lever 26, secured upon crank 22. By this means when a coupling is o ened by operation of an outside crank 23 t e signal will beraised, indicating the condition of the car. Located at each side of the car-body are the buifenframes 8, which may be of any suitable construction, as plates or bars, as shown in Figs. 4. and 5, respectively, which frames are solidly incorporated with the main framework of the car. Located sub stantially on a level with the l raw-head are the buffers 36, forming the outer portion of sliding blocks 37, mounted between the plates 8 and bearing backwardly against stiff buiier-springs 38, adapted to receive the shock of im act. The bars 7 are connected with the b ocks 37 and move backwardlyand forwardly with them and also by mopendent on the 'other, and together they will work in unison. By this manner of'mounting the draw-head it will be seen that sufficient rovision is made at all points for ample ackward and forward and also lateral travel independent of the car-frame, while the pulling power exertedthrou'gh the coupling-jaw is transmitted to the substantial portions of the framework.

The operation of my invention will'be readily understood from the foregoing descri tion, and it will be-found to provide an ei cientdevice for the objects in View and to erform its functions eontinuously'in asatisfactory and efficient manner. Various changes or modifications may be made inthe design, proportions; or various details of construction b the skilled mechanic but all such are to e considered as within the scope of the following claims.
