24 Claims.

My invention relates to automatic railway coupler mechanisms and more particularly to a form of operating rod normally associated with automatic couplers as used on American railways.

It is a well known fact among railway operat ing men that one of the principal difficulties in automatic couplers is to provide an anticreep that will operate satisfactorily under all sorts of conditions. It is well known, for example, that under present standard conditions the operating rod now used will on occasion swing away from the car body, tending to release the anticreep. If this happens to occur at the same instant that some force on the coupler tends to throw th lock upwards in the head, the lock is free to rise and may be elevated to such a point that the knuckle will be released and cause a train parting. 'Such a combination of conditions is relatively rare but it is, of course, desirable to eliminate th possibility entirely.

The object of my arrangement is to obtain greater stability of the operating rod when in rest position in order to resist any tendency of the handle to swing and cause rotation of the rod during train operation.

A more specific object of my invention is to devise an operating rod in the form of a one-piece structure and a bracket afi'ording support for the handle end thereof in such manner as practically to eliminate the possibility of accidental rotation of the rod.

A different object of my invention is to provide such a construction in the operating rod as to afiord relatively great stability therefor when in rest position by an arrangement such that rotation of the operating rod in a direction to disengage the anticreep and permit unlocking of the coupler will require the entire weight of the rod to be rotated about a pivot point remote from its neutral axis and on the side opposite such direction of rotation.

Still another object of my invention is to dc.- vise a combination of coupler operating rod and car body support for the handle end thereof as will substantially eliminate accidental rotation of the rod.

In the drawings,

Figure 1 is a top plan view of my novel arrangement as applied to a railway car.

Figure 2 is a fragmentary front elevation of the structure shown in Figure 1.

Figure 3 is a sectional view of the structure shown in Figures 1 and 2, the section being taken longitudinally of the car body and substantially in the vertical plane indicated by the line 3--3 of Figure 1.

Figure 4 is a sectional view comparable to that of Figure 3, illustrating a certain condition of rotation.

Figures 5 and 6 are further sectional views similar to that of Figure 3, illustrating a relationship of the parts under other conditions of rotation of th operating rod.

Describing the structure in detaihmy novel arrangement is shown as applied to the end sill 2 of a car body (not shown) with which may be associated in usual manner the coupler 4. As illustrated, my novel form of operating rod, generally designated 5, comprises the usual hook end 6 (Figure 2) for connection to the lifter (not shown) of the present standard E coupler. The hook end 6 merges with the short horizontal portion 8 which is joined to the diagonal portion Ill 20 and continued in a further horizontal portion l2 at one end of which may be formed a U-shaped loop l4 joining at one end the handle [6. -As illustrated, the entire operating rod 5 is made of a single bar of metal but a similar form could be made by welding several 'pieces together to approximate the shape and contour illustrated. The portions 6, 8, I 0 and I2 of my novel form of operating rod are substantially identical with the present standard operating rod as utilized with the standard E coupler.

As illustrated in Figure 1, the operating rod 5 may have the hook end 6 connected as at l8 to the lifter link (not shown) of the coupler 4, and the horizontal portion I2 of the operating rod adjacent the handle end may extend through the U-shaped portion 20 of the bracket 22 which may be Ifixed to the end sill 2 adjacent an end thereof in any manner, such as by bolts 24 (Figure 2). Th bracket 22 may be formed with a vertical web 26 receiving the securing means 24 and continued into the forwardly extending flange 28 at the end of which may be formed the beforementioned U-shaped slot or eye 20. The bracket 22 may also have the horizontal fiange-30 reinforced by diagonal beading as at 3|, said flange 3B affording a rest as at 32 for the bottom leg 34 of the before-mentioned U-shaped loop portion I4 of the operating rod. It should be noted that said bottom leg 34 seats upon the horizontal bracket 22 well to the rear of the eye 20 as well as forwardly thereof to the edge of the flange 30. The rod-receiving slot or eye 20 is elongated vertically to afford a clearance as at 36 beneath the portion l2 of the rod which passes therethrough (Figure 3) so that the rod will seat as at 32, as

vleft and pulled forward as far a possible. -respective positions of the loop I4 on the bracket 1 flange 30 are similarly illustrated at the left of Figure 1.

aforesaid, and not bear on the bottom of the eye 20. Clearance over the portion i2 is also aiforded as at 38 above the operating rod to permit the rod to be raised completely oil of the horizontal flange 30 when the handle I6 is elevated to the position illustrated in Figure 5 in the normal operation of unlocking the coupler. The upper end of the eye 20 may be closed by the roller or filler block 40 (Figure 3), retained in position by the cotter pin 42.

In the normal rest position, as illustrated in Figure 3, it should be mentioned that the only support for the handle end of the operating rod is at the seat 32 where the horizontal lower leg 34 of the loop l4 rests upon the bracket flange 30.

Reference to Figure 4 illustrates the condition that develops when the handle of the operating rod is rotated in a direction outwardly from the car body without at the same time elevating the rod. Such a condition would develop if any a-b normal force were applied to the rod, tending to rotate it in that direction. Under such conditions rotation of the rod is resisted by the fact trates how theseveral portion 6, l and iii of the operating rod are placed well to the right of the fulcrumpoint 44, about which the rod as a whole must pivot when it is moved in a rotation to release the anticreep and unlock the lock.

. The operation of unlocking the coupler b hand is illustrated in Figure 5 where it may be noted that application of force to the handle IS in the usualmanner elevates the handle end of the rod untilit engages the roller .40; said roller forming the fulcrum point about which the rod rotates for .that purpose. Under these conditions, the rod is lifted ofi of the bracket flange 30 and is free to rotate about the roller 40, as described. T .After'the operation illustrated in Figure 5, the

handle 16 is normally released by the operator and dropped back on the bracket flange 30 as at 46, and the weight of the handle and other portions of the rod returns it to its normal rest position, as illustrated in Figure 3.

The bracket 22 isof a size to accommodate on the flange 30 seats for the several positions which the handle end of the operatin rod may assume,

resulting from the variou operating conditions of the coupler, the reverse extremities of which are illustrated in Figure l. The dotted outline of the rod in Figure 1 illustrates its position when the coupler is angled to the extreme right and buffed back as far as possible, while the phantom outline of the rod illustrated in Figure. 1 shows its position when the coupler is angled to the extreme The 11f desired, the bracket 22 may be formed with adependingportion 48 with a'ledge Ellat its lower extremity affording a stop asat 52 (Figure 3) as a limit for: clockwise rotation of the rod. The extension 48 would have such a length as to providethe abutment at 52 in well known mannor for any of the several positions of the operat- -ing rod illustrated in Figure 1.

It is to be understood that I do not wish to be limited by the exact embodiment of the device shown which is merely by way of'illustration'and not limitation as various and other forms of the device will, of course, be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
