UNLOADING DEVICE.

Application filed February 12, 1923. ySerial No. 618,525.

To all whom it may concern.'

Be it known that OLE SUNDE, a citizen of Norway, residing at Roy, in the county of Pierce and State of l/Vashington, has in-v` vented certain new and useful improvements 1n Unloading Devices, of which the following is a specication.

This invention relates to improvements in unloading cars primarily intended for un loading logs for saw mills.

The prime object of the invention is' the provision of means for setting and locking the log holding means at the sides of the car, and to provide means for quickly reI leasing the log holding means when it is desired to unload a car.

The invention also comprehends improvements in the details of construction and arrangement of parts, which will be hereinafter described and particularly pointed out in the claimz In the drawings:

Fig. 1 is a perspective view of a car illustrating the application of my invention.

Fig. 2 is a similar View showing a detail of one of the log holding devices in released position,

Fig. 3 is a side elevation of a car shown in dotted lines and the invention applied in full lines.

Fig. 4 is an end view of the same.

Fig. 5 is a detail side view of the end of one of the beams of the log holding means.

Fig. 6 is a plan view of the log holding beam.

Fig. 7 is a detail section of 'the latch lever.

In the drawings, reference numeral 1 indicates the body of a flat car, and 2 and 3 indicate rails, one of which is higher than the other to slightly tilt the car sideways. The numeral 5 indicates heavy beams which are placed transverse of the flat car, each beam being slightly depressed centrally as shown at 5a. 6 indicates strap iron reinforcements for protecting the tops of the beams 5, the strap irons being bent at their ends to the side of the car and are formed at their terminals with bearings 7, which support a shaft 8 also mounted in bearings as indicated at 9 and 10.

One end of the shaft 8 is provided with a crank 11, to which is pivoted a link 12, pivoted to a second link 13, which in turn is pivoted to a lever 14, mounted on the plate 15 secured to the end of the body of the car. Pivoted at 16 on the lever 14 is a catch lever 17 carrying a pin 18 spring pressed at 19 to cooperateL with holes 28 for holdingvthe lever 14 at a predetermined adjusted position.

Rigid with the shaft 8 are cams 20, each y being provided with a shoulder 21, the purpose of which will behereafter explained.

22 is a strap iron reinforcement for the central position of each beam 5, the end 0r ends of the strap iron terminating short of the ends of the beam, and form eyes 22a. The central portion of the ends of each beam is cut out, as at 5b and hinged between the eyes 22EL are the ends of curved arms 23, the outer ends of which are hinged t0 the upper ends of supports 25. Each support 25 coacts with the cam 2O and being retained in operative position by the shoulder 21. A U-brace 27 is secured to the ends of the strap irons 6 to prevent the supports 25 from projecting too far beyond the sides of the car when in inoperative position.

ln the operation, the lever" 14 is actuated to the position shown in full lines in Fig. 4, which positions the shoulders 21 against the lower ends of the sup-ports 25 and holds same in a vertical position, thus holding the curved arm 23 in position above the top of the beams 5 to prevent logs or the like rolling off the flat car. c

To unload the car, the handle of the le- -ver 14 is grasped, the fingers encircling the handle 0f the latch lever- 17, thus compressing the spring 19 and releasing the pin 18 from the holes 28, which allows the handle 14 to be drawn to the dotted position shown in F ig. 4, transmitting the motion through the links 12 and 13 to the arm or crank 11, which in turn rotates the shaft 8, thereby causing the cams 2O to be rotated to turn the shoulders 21 down and thereby release the supports 25. When the supports drop, the arms 23 fall into 'the cut away portions 5b of the beams 5, and by reason of the inclination of the car, the logs roll off.

The car can be equipped with shafts on opposite sides as shown in Fig. 4 and an operating lever 14 provided at each end of the car, thus enabling a car to be'unloaded from either side and permitting the oper-- ator to stand near the side of the car which is away from the side where the unloading side of the car is to be used at all. times for discharging the load, only one oi' my devices need be installed, thereby providing a support near each end of that side of the cai1 which is to be used for discharging the load. F or instance, in Fig. l, assuming that the side of the car shown in the foreground is to be always used as the side from which the unloading is done, the rail 3 (adjacent to the stream or pond at which the unloading is to be done) will be' in a lower horizontal plane than the rail 2, thus causinfr the side of the car shown in the foreground to be tilted downwardly with respect t0 the side of the car shown in the background. An operator standing` atrthe left hand end of the car can grasp the operating lever 14, causing the two supports 52,5 to be lowered and permit the logs or poles to roll by gravity from the and at the time be entirel'y out of danger 'from the falling load.

While l have shown and described a particular form of embodiment of my invenmesses tion, l am fully aware that many minor changes will readily suggest themselves to others skilled in the art, and I therefore desire to avoid being limited to the exact embodiment herein shown and described.

lfhat I. claim is:

ln combination, a flat car, beams secured across the same, strap irons secured to the top ef the beams and extended over the ends oil the beams and downwardly below the same and provided with bearings, the ends ot the beams being recessed., curved arms hinged to the beams and adapted to be lowered into the recesses, hinged supports hinged to the outer ends of the arms, a shaft mounted in the bearings, shouldered cams mounted in the bearings and with which the lower ends of the supports cooperate to hold the supports in vertical position, and guides for preventing the supports swinging outwardly when released by the cams.

ln testimony whereof ailix my signature,

OLE .SUNDE
