MEANS FOR LQADING AND UNLOADING CARS.

Application. filed January 31, 1928,?` Serial' No. 533,008.

To all whom it may concern:

Be it known that we, CHARLES E. LIND- sAr and CLINTON V. OenrN, both citizens oi" the United States, and residents, respectively, of Albany, in the county ofAlbany and State of New York, and thercity of New York, borough of the Bronx, iii the county of Bronx and State of New York, have invented a new and Improved Means for Loading and Unloading Cars, of which the following is a full, clear, and exact description.

The present invention relatos to new and useful improvements in means for loading and unloading cars, andv it pertains more particularly to a device of this .character especially adapted for handling railway ties.

AIt is one of the primary objects of the invention to construct a device of this character so that it is capable of use with cars of various types but more particularly for use with cars of the so-called gondola type.

It is a further object of the invention to construct a device of this character so that it may be readily attached to and detached from cars, and, at the same time, will be securely held in operative position on the car.

It is a further object of the invention to provide means whereby the improved device may be operated from the air-line of the car. v i

It is a further object of the invention to construct a device of this character` which is adjustable in order to meet varying op erating conditions.

With the above and other objects in view, reference is had to the accompanying drawings, in which Figure 1 is a view in elevation partly in section, of the improved device in operative position;

Fig. 2 is a detail sectional view of the lower portion of the cylinder showing the piston at the lower end thereof;

Referring more particularly to the drawings, the reference character 10 designates a freight car of ordinary construction and of the type with which the device illustrated in the present invention is adapted for use.

The device comprises a main tubular member 11 and pivotally secured to the lower end thereof is a cani or the like 12. Mounted on the cam 12 is an arm or bar 13, and said bar carries a block 14 adapted for engaging the sill 15 of the car 10. The block 11 has a serrated portion 16 adapted to engage a plurality of rack teeth 15 on the bai' 13 in order that the block 14 may be adjusted longitudinally of the arm 13.

`The cam 12 is mounted upon a .shaft 17 and secured to said shaft 17 is a lever 18 provided with an operating handle 19. By this construction it is apparent that as the oper ating lever 18 is moved to position above Ithe cam or opposite to that shown in Figure 1, the bar 13 will be reciprocated to the left in Figure 1, and the block 14; will disengage the sill 15. When, however, the device is positioned for use with the operating lever in the position shown in Figure 2 and the block 14 is adjusted relatively to the bar 13 to engage' the sill 15 of the car 10, it is apparent that if the operating lever 18 be moved to the position shown in Fig. 1, the cam will serve to cause the block 14 to bite or engage the sill 15 to securely clamp the tubular member lin position withl respect to the car.

The reference character 20 designates a collar surrounding the tubular member 11, and said collar has a plurality of oppositely disposed arms 21. Each of the arms 21 is provided with a block of wood or other suitable material 22 adapted toengage the .side of the car to prevent rocking of the tubular member 11 under operative conditions. These blocks are made 1n various sizes and are mounted in such a manner as to be interchangeable. As shown in Figure V3, the ,collar 2O provided. with a pin similar member' 23 adapted to engage the tubular member l1 to maintain the collar in adjusted position thereon.

A cylinder 24 is adapted to be received within the tubular member ll, as more clearly shown in Figures l and 2. This cylinder is provided withv a plurality ot` rece s' o and carried in the housing 26 formed on the tubular member ll, is a plurality ot pawis 2.7 adapted to engage the recesses 25 to maintain the cylinder 24 in adjusted position relative to the tubular member 1l. Mounted within the cylinder 24 and adapted to rei'fiprocate longitudimilly thereof, is a piston 9S, and said piston 28 carries a piston rod 29, the upper end of which is provided with a pulley 30. As more clearly shown in Figure 4, this pulley is mounted in a yoke 3l, and the pulley yoke 3l is swivelled to the upper end of the piston rod 29 as designated by the reference character As more clearly shown in Figure G. a valve housing` 323 is secured to the upper end oi the cylinder-Q4, and leading into said valve housing are two three-way valves 35, said three-way valves being arranged in diametrically opposite relation one to the other. lilounted in the upper portion ot the valve housing 3B at I liai'netrically opposite points are two check valves 36 and said check valvesI 3G are adapted to permit ot' fluid entering the cylinder therethrough but are adapted-to seat upon the exhaust or fluid from the cylinder 24. Each ot these check valves .is provided with a bleed port 37, the purpose ot which will be hereinafter more fully described.

Leading from the valve housing` 33 to the interior of the cylinder at a point spaced from the upper end ot the cylinder are passages 39, ot which but one is shown in 1figure (i, and these passages are positioned one opposite each ot the three-way valves 35. Each o'l these three-way valves has a nozzle or the like 39, by means et which a hose or other suitable line 40 may be attached.

rhe valve hoi'ising 33 is formed with a partition 4l which closes the upper end of Vthe cylinder and carried by said partition 4l is a stutiing box 42 through which the piston rod 29 passes. "his valve housing is carried by a tubular member 447 the upper end oi which is split as at 45 and provided with a pair of lugs his tubular member 44 is provided on its interior with a tapering` annular shoulder 47, and said annular shoulder 47 is adapted to receive the lower end of a tubular standard 48 to position said tubular standard as more clearly indicated by the reference character 49, said annular shoulder forming a supportfor said tubular standard.

Mounted within the lugs 46 is a shaft 50 and said shaft has one of its ends screwthreaded. Mounted upon the screw threaded end of said shaft is a nut and upon the other end of the shaft 50 there is an operating lever By this construction it is apparent that as the nut on the shaft 5() tightened, the adjustment is made which permits the split end 45 ot the tubuiar member 44 being clamped about tie tubular standard 4S upon operation ot the lever 5l on its screw threaded end et the shalt 5t).

As more clearly shown in Figure 5, the tubular member 44 is provided with angularly disposed lugs GO, and pivotally mounted in the lugs are dependent angularly disposed arms G1. rhese arms Gl are each provided with hook extremities and as more clearly shown in Fig. l, the hook extremities G2 ot these arms are adapted to engage over the upper edge 63 of the side ot the car to which the device is attached.

Projecting trom the tubular member 44 a web 64 and mounted in openings 65 in said web are arms These arms 66 are adapted to engage openings 67 in webs 68 carried by the arms 6l in order that said arms may be adjusted about their pivotal point to meet various conditions in the size ot the upper edges of the cars with which they are adapted to engage.

Slidably mounted upon the tubular member 4S is a collar 70, andpivotally connected to said collar TO as at Tl, is a yoke T9.. This yoke T2 is provided with a screwthreaded socket T3, and secured therein is a supporting leg T4 oit a suitable boom 75. To the upper end ot this leg' 74 is secured a housing 76, in which is mounted a pullev T7. The outer end ot the boomf is pivotally connected as at 7S, to the housing 76, and the inner end of said boom T8 carries a yoke member 79, which is pivotally connected as at 8O to a collar or the like 91 mounted tor 'tree rotary movement upon the upperl end ol the tubular member `fiecured to the exterior oi the tubular member 48 and rigidly connected thereto is a strap 92, and the lower end ot the collar 91 Y carries a detachable ring 93 adapted to engage said strap 92 to prevent the collar 91 rising from the upper end ot the tul'iular member 48. This ring 93 is secured in position by means ot cap screws or the like 94.

Mounted in the yoke 'J9 is a pulley 8l, and said pulley is adapted to aline with the pulley 77 heretofore mentioned. Secured to the yoke 79, as at 82, is a rope or cable 83, and said rope extends downwardly within the tubular member 48 about the pulley 90 and upwardly over the pulleys 8l and T The tree end of this rope S3 is provided with a suitable grapple 84, by means of which the material to be loaded into the car or removed. therefrom is grasped. Thilo (iii bij

in the present instance the material-haudlinp; means has been illustrated as a grapple, it obvious that the same may be a bucket, sling', or other element suitable for operation upon the material to be handled.

The device operates in the 'following manner Alfter the device has been positioned, the grapple 84ris engaged with the material, ,vhicl'i in the present instance is illustrated as a railroad tie 90, which is to be elevated to a position Where it can be placed in the car, Alfter this has been done, the valve 35, to which the hose 2110 .is connected is rotated to permit air lin'essure to enter the cylinder 241;. As this air enters the cylinder through the passage 38 and the check valve 36, the cyliiuler is forced downwardly, and through the medium ol' the cable which passes around the pulley 30 carried by the piston, the grapple 84; is elevated to the position shown in Fig. l.

Alter this has been done, the grapple is swung' around to a position over the car and the three-Way valve is again turned to permit ot the exhaust ot the air in the cylinder under the Weight of the material elevated by the grapple The air lirst exl'iausts through the opening,l 3&5 into the Valve chamber 33, from whence it passes through the three-Way valve 35 to the atmosphere. As the piston lifts within the cylinder to a position Where it closes the passage 38, the air above the piston in the cylimler `forms a cushion therefor. This air is then placed under compression Which is bled through the port 37, thus allowing the piston to roach a position in the top olf the cylinder'. To vfurther operate the mcclmnisln it is only necessary to permit air to tlow imvardly ot the cylinder by a proper positioning' ot the tl1ree-Way valve and the piston will again be depressed, as above described.
