CAR-STAKE.

Specification of Letters Patent. Application filed December 18,1911.

Patented Jan. 27, 191 1. Serial No. 666,460.

To all whom it may concern:

Be it known that I, THOMAS M. ScHMITz, a citizen of the United States, residing at Cranbrook, British Columbia, Canada, have invented certain new and useful Improvements in Car-Stakes; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cars and has especial reference to cars designed for conveying saw logs but is of course not confined in its utility to such specific use.

An object of the present invention is to provide a car with stakes, sleepers and other parts which are especially adapted for retaining logs upon'the car and with improved means for releasing the log-retaining elements.

A further object of the invention is to provide a transverse sleeper for a car having means for retaining one stake upon one side permanently in position and with a pocket formed upon the other end to retain the stake-slidably in position, with chain and releasing means for holding the bottom of the stake removably in the pocket.

A further object of the invention is to provide improved means for connecting the tops of opposite stakes so that the bottom of one stake may be released to dump logs from the car.

A further object of the invention is to provide detailed parts for carrying into effect the several main objects of the invention.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more-fully described and claimed.

In the drawings Figure 1 is a view in end elevation of a conventional car with the invention applied thereto. Fig. 2 is a perspective View of the releasable chain connecting means. Fig. 3 is a perspective view of one of the stirrups employed for the top of the stakes. Fig. 4 is a perspective View, broken, of one of the sleepers.

Like characters of reference indicate corresponding parts throughout the several views.

A car, indicated generally at 10, of any ployed by placing transversely across such car a plurality of sleepers indicated as a whole at 11. Each of the sleepers is provided. at one end with a socket 12 preferably produced by a strap 13 secured to the sleeper in any approved manner, as by bolts .14.

Into this socket 12 a stake 15 is inserted substantially in the usual manner employed upon logging and other cars. At its opposite end'the sleeper 11 is provided with a pocket 16 open at the outer end and preferably though not necessarily produced by a strap 17 secured to the sleeper as by bolts 18. Into this pocket 16 a stake 19 is set and is secured therein by means of a chain 20 which is secured to the stake as indicated at Fig. 1

and connects with the grab hook 21. This grab hook 21 is provided with a long shank 22 and is pivoted as at 23 to a long link 24: which in turn is rigidly secured to the side of the sleeper 11.

Slidably mounted upon the link 24: is a keeper 25 caried at the end of a rod 26 which preferably extends outwardly adjacent the outer lines of the car and is adapted to slide over the long end 22 of the grab hook to re tain such grab hook in engagement with the link 24. It will be apparent that when the keeper 25 is in position as shown at Figs. 1 and 2, the grab hook will'hold the chain 20 and therewith the stake 19 within the pocket 16.

At its upper end the stake 19 is connected with the stake 15, such connection being provided by a stirrup 27 having a roller 28 and a chain 29 connected therewith, so that the stirrup may be slidably forced down over the end of the stake and maintained in position by a pin 30 inserted through holes 31.

The chain 29 is connected with a chain 32 which is in turn connected with a stirrup 33 similar to the stirrup 27 and similarly held in position upon the stake 15 by a pin 34. The chains 29 and 32 are held in connection by a grab hook 35 similar to the grab hook 21 and with a link 36 and keeper 37 similar to the link 24 and keeper 25. The keeper 37, however, does not require any rod, as the rod 26, to operate the same.

In operation the logs are placed between the stakes 19 and any log which comes in contact with the movable stake 19 must bear upon the chain 20, whereby increased tension is applied to hold the stake in the pocket 16. When the logs have been properly loaded the stirrups 27 and 33 are placed in position, forced down as far as the height of the logs will permit, and drawn together and coupled by means of the chains 29 and 32. hen he logs are to be unloaded the rod 26 is pulled from the side of the car opposite the pocket 16, which releases the chain 20 and permits the lower end or the stake 19 to swing outwardly but held from becoming lost by being still attached at the top to the opposite stake. hen all of the logs have been removed from the car the stakes are put back in the position as shown.

It will be apparent that the use of the rod 26 permits the release of side of the car opposite that upon which the load is to be dump-ed to prevent the operato r from becoming injured in such act.

the load from the I claim V I In a device of the class described, a bolster having an open socket at one end, a stake reinovably erected in the open socket, a chain secured to the stake and extending toward the opposite end of the bolster, a link, a hook carried by the link and adapted to engage the chain, a keeper slidable upon the link and the shank of the hook, and an opcrating rod secured to the keeper.

In testimony whereof I aflix my signature in presence of two Witnesses.
