LOGGING-BUNK.

Application filed November Specification of Letters Patent.

Patented June 20, 1911.

11, 1910. Serial No. 591,912. i

1 '0 all whom it may concern:

Be it known that I, J osnrrr N. PETERSON, a citizen of the United States, residing at Ellison Bay, in the county of Door and State of Wisconsin, have invented certain new and useful Improvements in Logging- Bunks, of which the following is a specification. 7

This invention relates to means for unloading logs from cars and is in the nature of a logging bunk for fiat cars.

In many forms of devices heretofore use for unloading logs from cars it was necessary for the workmen to stand in such positions as to'endanger life and-limb and the primary objectof this invention is to provide means whereby logs may be unloaded from flat cars without entailing any danger whatever of theinjury of the workmen during the operation. 4

A further object of the invention, is to provide a logging bunk for flat cars of such simple construction that it maybe conmake and use my invention, I will now proceed to fully describe its construction and operation, in connection with the accompanying drawing, which illustrates a'preferred embodiment ,and in which Figure 1 represents a view inside elevation of a fiat car upon which is erected my improvedlogging bunk; Fig. 2 represents a top plan view of the same; Fig. 3 represents a detail view, on an enlarged scale, partly in elevation and partly intransverse section, of one of the cross rails, a stake, a stop and --a chain hook; and Fig. 4 represents the parts shown in Fig. 3 on the same scale and in side elevation.

Like reference characters mark the same parts in all of the figures of the drawing.

Referring specifically to the various parts I as illustrated in the drawing, 10 indicates the body of an ordinary fiat car supported, in the usual manner upon trucks 11, 11, of any preferred construction, such parts being of ordinary construction and forming a bunk. l

Upon the top of the body 10 of the car, and transversely thereof, are secured the rails 12 upon which the logs are to be piled longitudinally of the body. These rails may but ordinary railroad rails, as shown inthe present embodiment of the invention, are readily accessible and answer remarkably well for my purposes, there being usually on hand at railroad shopstor camps, numbers of pieces of worn rails long enough for this use. p Each rail is partially cut away on one side at each. end, as shown at 13, forming, between the rails and suitable straps 14 secured to one side of each rail at each end by suitable means such as bolts 15, recesses as at 16,

in which are mounted stakes 17 on pivots 18,

the stakes being adapted to swing transversely of the car on pivots 18. These stakes are'preferably flat iron or steel bars.

Mounted in bearings 18 secured to the under faces ofthe rails 12 are two longitudinal bars 19, extending substantially from of the stakes 17, there being secured to each bar, under each stake, a stop 20 having teeth 21 on its upper surface meshing with similar teeth 22 on the lower end of the stake.

Formed by bending one end of each bar 19 at substantially a right angle, is a lever 23,

or such levers may be separate from the barsand secured thereto in any usual or preferred manner.

Pivotedto the side of the car boll y are a number of hooks or buttons 24, one in position to rest on the outside of a lever 23 and securely hold it against the side of the car when desired and thus hold its bar 19 against turning, or to be swung aside out of contact with the lever, thus leaving the bar 19 free to turn in its bearings. Each lever 24 is provided with a laterally projecting handle 25- for convenience in manipulating it and there is astop pin 26 projecting prev'ent' each .hookfrom dropping below its basis upon which to erect my improved be specially constructed for use in the bunk end to end of the car under the lower ends froln'the side-of the car body in position to position of engagement with its lever, as clearly shown at the right hand end of the Fig. 1

Mounted rigidly on the bars 19, one preferably alongside of each rail 12, are chain claws 27, arranged in pairs, one claw on each bar 19 being opposite a claw on the bar 19 on the opposite side of the' car. These claws are so positioned on the bars 19 that when the stakes are in upright positions, the claws are at the limit of their downward movement.

The operation of my" invention may be described'as follows: The car being loaded with legs, as at 28 in Fig. 3 where the ends of a portion of the logs are outlined, the stakes 17 will be upright and will be held in upright position by the stops 20 on the bars 19, the bars being held the hooks or buttons 24, as illustrated in Fig. 1.. A chain extending over the logs in the position indicated in Fig. 3"willbe engaged by the chain claw 27 and will hold against turning by the logs down on the body of the car. It being desired to unload the logs off the side of the car,-a workman, standing at the end of the car and entirely outof the path of the logs when they roll off the side of the car, turns up the button 24, which passes off the lever 23 and releases it, so that outward movement of the logs against the stake .17 will swing the stake outward on its pivot. The engaggcipent of the teeth-22 of the stakes with the h 2]. of the steps 2-0, will cause the bars 19 to turn in the opposite direction and the chain claws 27, being rigidly secured on said bars 19, will be turned up ward, thus permitting the chains to be drawn off the upturned ends of the claws and release the logs so that they will roll off the side of the car. By again turning the lever 23 down to the position of Fig. l, and securing it with the button 24, the bar 19 will be turned to position to again bring the stakes 17 to their upright position, the claws 27 being turned down again to tighten the chains over the logs.

The simplicity of the construction and operation of my invention will be obvious from the foregoing and while I have specifically described the construction of the various parts, it will also be obvious that changes in such specific constructions within reasonable limits may be made without departing from the spirit and scope of the invention.

Having thus fully described my invention, what I claim -is new and desire to secure by Letters Patent of the United States, is

1. In an apparatus of the character described, the combination with the car body, of transverse rails upon the body, stakes pivotedto the rails at their ends to permit them to swing transversely of the car, a bar journaled to the rails below the stakes, means for locking the bar against turning, toothed stops on the bar, teeth on the stakes to engage the teeth of the stops, and chain claws secured on the bararranged to act simultaneously with the stakes.

2. In an apparatus of the character described, the combination with the car body, of transverse rails upon the body, stakes pivoted to the rails at their ends to permit them to swing transversely of the car,- a longitudinal bar journaled to the rails below the stakes, means for locking the bar against turning, and stops on the bar which engage the stakes to prevent the swinging of the stakes when the bar is locked.

3. In an apparatus of the character described,'the combination with the car body,

of transverse rails upon the body, stakes pivoted to the rails at their ends to permit them to swing transversely of the car, a longitudinal bar journaled to the rails below the stakes, means for locking the bar against turning, toothed stops on the bar, and teeth on the stakes to engage the teeth of the stops.

4. In an apparatus of the character'described, the combination with the car body, transverse rails upon the body, each rail having a recess at each end, stakes pivoted one in each recess of ea'ch rail and adapted to swing transversely of the car, longitudinal bars journaled to the railsbelow the stakes, means for locking the bars against turning, toothed stops on the bars, teeth on the stakes to engage the teeth of the corresponding stops, chain claws carried by the bars, the claws of one bar being directly opposite the claws of the other bar, and chains for engagement with the claw bars.

In testimony whereof I aflik my signature in presence of two Witnesses;

JOSEPH N. PETERSON. lVitn'esses A. HOGENSON, Mrs. MARTIN ONESON.
