WILLIAM L. LENTZ, OF TUCKAHOE, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS,

TO GENERAL STEEL CASTINCS CORPORATION, GRANITE CITY, ILLINOIS, A COR- PORATION OF DELAWARE DEFLECTING PILOT STRUCTURE Application filed August 22, 1927. Serial No. 214,600.

My invention relates to railway rolling Stock and consists in an improved pilot beam and coupler arrangement particularly adapted for use on freight or passenger locomotives at the front end of the locomotive.

The main object of my invention is to provide a pivoted coupler which may be moved to and from a functioning position and securely held in either position and which can be operated readily by one man.

I also desire to provide a pilot upon which the coupler is mounted which is adapted to receive the head of the coupler and its shank when the same is lowered from a functioning position so that the coupler does not project beyond the pilot to a position where it would impale an object onthe track and preferably where it forms an impact resisting portion of the pilot.

Another object of my invention is to provide a coupler device which may pivotvertically as mentioned and also may pivot horizontally.

Another object of my invention is to provide for vertical adjustment of the pilot on the pilot beam without undesirably aifecting the positioning of the coupler device When in raised functioning position.

Another object of my invention isto provide means for preventing the nose of the pilot from digging into the road bed if the pilot is depressed from its normal position.

Another object of my invention is to provide an improved pilot beam and uncoupling device for the swinging coupler arrangement referred to.

These and other detailed objects of my invention which will be referred to in the specification are accomplished in the selected embodiment of my invention illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the pilot, pilot beam, and coupler device with thelatter in raised functioning position.

Figure 2 is a longitudinal vertical section through the same parts, with the coupler device shown in elevation, and with the coupler in depressed non-functioning position.

Figure 3' is a top view of the same structure with a portion sectioned to more clearly 1llustrate the details of the assembly.

Figure 4 is a front elevation of the pilot and pilot beam, the coupler being omitted.

Figure 5 is a front elevation of the pilot beam With the pilot removed.

In the drawings, the front end of the 1000- 4 and immediately beneath opening 2 is a cross tie 5. The beam is provided with detachable brackets 125 for supporting the sides of the pilot.

The pilot 4 is adjustably mounted upon the pilot beam 1 by means of bolts 6 passing through slotted openings 7 in the pilot.

The base of the pilot is of the usual triangular form, and the sides of the pilot slope upwardly and inwardly in the usual manner. Near the intersection of these converging sides, they are partially cut away to provide an opening in front of the pilot beam opening 2 and to provide a recess below such opening adapted to receive the coupler shank 9 When the latter is in the position shown in Figure 2, in which position the coupler head 10 forms the ridge or backbone of the pilot similar to the ridge formed by the intersection of the front walls 'of the ordinary pilot structure. When so depressed, the shank coupler does not extend forwardly of the pilot to form an elevated projection of restricted area which is likely to impale and unnecessarily damage an object on the track, as is possible with the ordinary pilot coupler.

At each side of the coupler shank the pilot is provided with flanges 8 in which are bearings 13 for pin 11 which passes through a slot 12 extending transversely through the coupler shank 9.

The portion of the coupler shank which extends rearwardly of pin 11 passes through the opening in the pilot and the corresponding opening 2 provided in the pilot beam 1 and terminates in a hollow portion 14 adapted to be filled with lead or other material for increasing the weight of this portion. This rear extension on the coupler shank forms a counterbalance for the coupler head and makes it possible for a single workman to readily shift the coupler from the depressed position shown in Figure 2 to the elevated position shown in Figure 1, in which the coupler may function to transmit, through pin 11, the draft and bufling forces between the locomotive and other rolling stock coupled to the front end thereof. The coupler may be held in this elevated position by a pin 15 seated in suitable bearings 16 provided in the front portion of flanges 8 and passing through an elongated slot 17 in the coupler shank 9.

Preferably the forward portion of the coupler device is a little heavier than the rear portion so that when the coupler is depressed, as shown in Figure 2, the shoulder 18 provided on the rear end of the device will engage the lower face of a suitable part of the locomotive frame such as B. By utilizing a separate element 19 for engagement by the shoulder 18 the relative position of the pilot and coupler may be maintained irrespective of variations in the vertical adjustment of the pilot on the beam. The coupler may be positively retained in its lowered position by the engagement of pin 15, with the upper face of a suitable lug 20 provided on the top face of the coupler shank 9. Adjacent to the bearing 16 in flanges 8, the pilot is provided with su tantially horizontal surfaces 21 on which pin 15 may be laid when withdrawn from the coupler shank for the purpose of permitting the shifting of the coupler.

By locating both pins 11 and 15 in the pilot, the coupler shank is maintained in horizontal position, when elevated, irrespective of any variations in the relative position of the pilot and. pilot beam.

ofte

It will be noted that the transverse slot 12 in the coupler shank 9 is round at the center of the shank and is elongated at the sides of the shank, or in other words, flares from the center of the shank outwardly. This construction makes it possible for the shank to pivot horizontally on pin 11. Flanges 13 on the ilot diverge forwardlyand the sides 22 lripening 2 in the pilot beam diverge rearwa ly in order to accommodate such horizontal pivotal movement of the pilot.

My uncoupling device is adapted to accommodate the coupler in either position and comprises the usual uncoupling lever 24 extending longitudinally of the pilot beam and journalled in suitable brackets 25 mounted on the beam. The lever is provided with a forwardly extending operating arm 26 which is connected by a chain 27 to the locking pin 28 of the coupler. The ends of the uncoupling lever are provided with operating handles 29 which extend forwardly and downwardly and inwardly. When the coupler shank and head are in the elevated position shown in Figure 1, the uncoupling lever is held in the position indicated by the engagement of the ends of its handles 29 with a plate 30 pivoted at 31 on the front face of the pilot beam. When the coupler is to be lowered to its depressed position as shown in Figure 2, the plates 30 may be swung to the broken line position indicated in Figure 4, thereby uncovering recesses 32 (see Figure 5) in the front wall of the pilot beam which will admit the ends of the uncoupling lever handles 29 and permit the arm 26 of the latter to move to the inclined position shown in Figure 2, the handles 29 moving to the broken line position indicated in Figure 1 in which they contact with the upper ends of recesses 32. Lugs 33 on the pilot beam engage the plates 30 as shown to hold the latter in either desired position.

The front lower portion of the pilot is provided with lugs 23 immediately over the rail line and if the pilot is forced downwardly these lugs 23 will contact with and slide along the rails and tend-to su port the pilot so as to prevent the nose of the latter from being thrust into the road bed.

With my device, it is an easy matter for a trainman to shift the coupler device from functioning position to depressed position or vice versa, and in either position the device will possess all of the advantages of the ordinary structure in addition to possessing the particular advantages hereinbefore pointed out.

Preferably the pilot and pilot beam are formed of cast steel and each is made in onepiece, but it is apparent that these two parts might be formed integrally -or that elther might be made of built-up structure instead of being cast.,'

Preferably the coupler head 10, shank 9 and counterbalance portion 14 are formed in a single one-piece casting but these parts may be separately formed and assembled with each other if desired.

I contemplate the exclusive-use of these and such other modifications in the details of my invention as fall within the scope of my claims.

Attention is directed to the copending application of Einar G. Halhguist, Serial No.
