Specification of Letters Patent.

Application filed October 30, 1905 Serial No. 285,007.

- -The object of my invention is to provide a chock for holding-.logs on cars, trucks, andother means for-transportation, which chock may be readily released to enable the logs to be rolled from the car Without the necessity of a .person going to the side of the ear from which the logs are to be rolled.

It is also an object of my invention to improve the means for mounting the chock and to enable the chock to be. thrown into unloading or inactive position so completely as not to interfere in any way with the free rolling of the logs,

The invention involves various features all of-which will be fully brought out hereinafter I and particularly pointed out inthe claims.

' logs rest.

' Reference is to be had to the accompanying drawings, which illustrate'the preferred embodiment of my invention, and in which- Figure l is a plan view of thelat-car having my invention applied. Fig. l2 is an enlarged cross -section showing the guide rails for mounting the chocks and on which rails the Fig. 3 is a detail section showing one of the checks in unloading position, and Fig. 4. is a detail perspective of the stationary chock.

The invention is adapted to be used on flatcars, trucks, and on various other means for transportation on which logs and timbers may be loaded. As here shown, .it is illustrated applied to anat-carl@ Near each end of the` car is located a` pair. of railroadrails 11. These rails 'extend parallel with each other transversely ofthe car and may be mounted directly on the floor of the car or 0n a bunk or pillow provided for that purpose, As shown\best in Fig. 2, the rails A11 are 'laid sidewise on the support and are drawn down In' so firmly in place by means of bolts 12.

v drawing down .the rails the, 'comparatively sharpged'ges of the base-flanges cut into the support', whether it be the -floor of the fiatv'car ora bunk provided to carry the rails, thus making. thev rails absolutely rigid and' secure.

Said rails are arranged with the balls of the rails inward, and the balls are slightlyspaced apart to provide a channel for a chain 14, the purpose of which chain will be fully set forth hereinafter. The base-flanges of the rails are outward and project above the balls. The balls of the rails form a trackway on which the checks are movably carried, and the baseiiang'es of the rails, which project upward, y

(see Fig. 2,) serve the double function of sustaining the logs and of forming guard-flanges preventing the displacement of the checks laterally of the rails. The relatively sharp edges of the base-flangessink'into the logs, so as to prevent the car from being pulled out from under the log. This is especially useful when the invention is employedin connection with trucks, since in this case it is usual to carry `a group .of logs on two4 trucks which are connected only by the logs themselves. Two chocks are employed for each pair of rails, one chock at each end thereof. These checks are designated 15 and 16, respectively.

The ehocks 15-are adjustably carried on the balls `of the rails between the base-flanges. y

Any desired means may be employed for adjustably holding said chock. A

As shown in Figs. l and 4, the checks arev provided with pins 17, which enter openings 18, formed in the webs of the rails 11. The movable chocksl are free to slide on the walls of therails between the base-flanges, and

with the movable chock 16 the chains 14 are connected'. l Both of the ebooks 15 and 16 are of the angular form'best, illustrated in Figs.' 3 and 4, and the checks 16 are arranged with an essentially right-angular form, so that when moved to the ends of'th'e rails 11 the checks may be'thrown down into the folded position, (shown in Fig in which v vIn this position the chock lies below the upper edges' of the `rails 1 1 and entirely out of the wa y oflthelogs rollingfr'o'm the sani'e.n AtA the ends ofthelrails i adjacent' lto the adjust- 1 able checksl `1ffeyes vv19 are provided, qthrough f which the chains le pass.l Coacting with'A k :said eyes are claws 20, which are preferably 1 loo,

the claws. These claws are adapted removably to engage the chains le and the eyes 19, so as to prevent the chains from being moved *y through the leyes in such direction as will per-- ymit thedumping-chock's to reach the edge of the car and accidentally assume the inactive I'or unloading positionabove described In' the use of the invention` the logs are' loaded on the car and extend edfroni one pair of rails 11 to the other, the checks 15 and 16 being placed imposition so as to retain the logs in the fdesired arrangement.` The stationary chock's lvare held by the pins 17 and the movable checks 16 are held by the chains 14, eyes 19, and claws 20. When it is desired to unload the logs from the car or other conveyance on which the logs are laced, the claws 20 should be disconnected om the chainsla and the pressure of the logs allowed to slide nthe movable chock 16 out to the edge'of the car or the adjacent ends of the rails l l, whcreuponthe chocks will Jall down into the unloading position (shown in Fig. 3) and allow the unobstructed movement of the logs. It will be observed that this operation is performed by persons standing at the side of the car having the 'eyes.19 and claws 20, it being only necessary to disengag'e the claws from the chains 14 and to start the logs rolling toward the opposite side of the car. This avoidsthe extremely .dangerous operationi of a person going to the side of the car op which the logs ,are unloaded for the purpose of releasing the chock. ln the lumbering industry numerous fatal accidents occur'from this reason. 4 l

It is pointed outthat while it is preferable to employ railroad irons or rails, as used in theA drawings and hereinbefore described, guide-rails of other forms may be employed, in which, connection it is only essential that means be provided for forming a central paschain is-rove,` and `'apela-vv grappling-hook sagev for the chain, a surface on which the checks maybe slidably supported, and guardsurfaces at the sides ot the checks to prevent them from moving laterallylfroin the rails.

Various changes in the form, proportions, and lminor details of my invention may be re sorted to at will without de arting from the spirit and lscope thereof` llience l 'consider myself entitled to all such variations asmay lie within the terms of my claims.v -A
