To all whom it may concern:

Be it known that I, GEORGE AUGUs'rUs Hnnnon, a subject of the King of-Great Britain, and atresident of the town of Pembroke, in the Province of Ontario and the Dominion of Canada, have invented certain new and useful Improvements in Car- I Stakes, of which the following is a full dei site stakes and engages with the top of the logs thereby holding the logs compactly together and preventing their rolling over each other due to vibration when the car is running, to prevent the stake locking means from inadvertently loosening and generally to simplify the several parts and adapt the same to better perform the functions required of them. r V

For a complete understanding of my invention reference is made'to the following L of the tubular rod specification and accompanying drawings ill which,

' Figure 1 is a side elevation bodying the present invention. Fig. 2 is a fragmentary plan view of the sam I Fig. 3 is an end view of the car illustrate in Fig. 1. g I Fig. 4 is a fragmentary perspective view carrying the stake looking means. v Y

Figis a rspe'ctive tive form of stake.

V Fig. 6 is a fragmentary side elevation, partly sectional, of-the tubular member carrying the stake locking means andshowing an alternative method of actuating the same.

of a car emview of an alterna Like ch'aractersof reference refer to llke parts in the several figures.

Referring to the drawings, A represents.

7 a railway lumber car of the usual type equipped with the usual stakes B. The sides of the car'A are-provided with a plurality of equidistantly spaced brackets 10 which consists of a back wall 11' having a plurality of orifices therethrough whereby the brackets may be secured in position by bolts or the like.

The side walls 13 of the brackets are formed integral with the back walls 11 and i the; inner face of thesaid'side walls taper toward the bottom, thefr'ont of the brackets being opened and designed to be closed'by a tapered locking member l l 'provided with an offset end 15 which is the tubular spindle 16. This tubular spindleis slidably mounted in the brackets 17 located intermediate of the brackets 10 and the end of the spindle is formed with a threaded portion with which the screw 18 makes threaded engagement."

This screw is rotatably mounted in'the bracket 19 and 't'o prevent longitudinal movement of'the screw a pair of collars 2O rigidly secured to are mounted thereon and designed to engage T with the. opposite faces of the said bracket.

Rotary motion is transmitted to the screw 18 byth-e hand lever 21 and when the spindle 16 has been moved to the-desired position'inwhichthelocking members 14 engage withthe'brackets '10, the hand lever 21 is engaged by a locking member 22, o thatalthough the car may be subjected to undue vibration, there 'is no liability of the 4 a screw 18 working loose. 7

1 The car stakes B' 'consist of a'plurality of tubular members 23 having-their outer wall corrugated or serrated as shown at 24, thelowerends'of the tubular 'members,

being provided with a tapered portion 25 designed; to engage with the'bra'ck'ets 10.

The upper end of the stakes'are provided with enlarged heads '26 'which may consist of flanges threaded or otherwise fastened said stake.

thereon or may be formed integr l' ithn the These car'stakes are located along both lateral faces'of the car A,' being' arranged in pairs directlyfopposite eachother and when the caris loaded with logs in the manner shown in Figi3, the chain 27 or other flexi ble member extends across the top of the load to preve'nt displacement and rolling of the-logs w This chain is formed of two portions with the-outer ends of each provided with" elliptical links 28 adapted to T engage with the stakes B and when the chain is being tight ened these links will engage with the corrugations 24. 7 g

' In tighteningthe chain it is only necessaryto adjust the length of the same on the lever downwardly, and the chain will be tightened.

Referring now to Fig. '5,- an alternative I to those already describechbeing providedwith tapered ends 25 to engage with the -brackets 10.

In Fig. 6 an alternative means for actuating the locking members is illustrated in which the spindle 17 is provided with an nular flanges 32 adapted toembracethe enlarged end 33 ofthe screw 34 making threaded engagement with the brackets 35 mounted on the car, which screwis provided with a hand lever 36 wherebyit is manually actuatedi WV hen a car equipped in this nature is in use,-the stakes B-arepositioned and-the car loaded with logs-or lumber whereupori the chain 27 is positioned witli the links =28-engaging the corrugations or serrations-2a of the stakes andthe lever- 29' is then adjusted and on depression of the lever the chain 27 is tightened on the'load.

lVhen unloading. this car the operator r0- tates the hand lever 21 so-movingthe tubular spindle 16 in a longitudinal direction thereby withdrawing the locking members 14 from engagement with-the brackets 10 and permitting the stakes under the pressure of the load to' be moved latera-llya and thus simultaneously released.

lVhen the' stakes'warefreleased, the chains 27 prevent the stakes fromfouling withthe logs and it will be readily seen that by providing the serratio'nsor corrugations, the chain cannot slip.

Itwill be understood that-the tubular spindle16 does not rotate, but only moves in a longitudinal direction and it will also be seen by referenceto- Fig' 1, that the screw18 is only capable of rotation and does not move in a longitudinal direction; the necessary force to actuate thespindle 16 beingderived. from the rotation: ot-thie screwl lVhen the locking members it are actuated by that typeof theinvention illustrated in Fig. 6, the lever 36 is manually rotated and the screw 34- moves in a longitudinal direction drawing the spindle-17 withit to' disconnect the members l lrfrom the 'braelr -jets-10.- V

One of: the chief differences between this type'ofmechanism and that illustrated in Figsi 1 andQ, istthat the screwsfiltinmoving.:longituc'linally restricts the passage'be tween adjacent cars, so that the operator has to stand well between the cars when actuating-the'lever ti, whereasinthat form 1llustrated in Figs. 1 and 2, the screw 18 does not move longitudinally and there is always sufficient clearance between the cars to permit of th e" operator of the lever '21 standing without 1 discomfort.

From this description it will be seen that I have invented a car" stake F which can. be advantageously employed on lumber cars and wherein, the several stakes on one side of' the car can be simultaneously releasedto liberate the lumber, the several parts being ,otan extremely simplenature and not liable to get out of repair:

As many changes could bemade in the above description and many apparently widely dilferent embodiments of my invention within the scopeot the claims constructed without departingzfrom the spirit or scope thereof; it'is intended that all matter; contained in theaccompanying specification and drawings sha'll beinterpreted as illustrative and not in a limited sense:-

lVhatI claim as my, invention is laTh e combinationwith a car of a plurality of stakes operatively mounted -there on-and meansfor'simultaneo-usly releasing i said stakes: consisting of locking members; a non-rotatable and longitudinal movable spindle carryingsaid members, and a screw coacting with the: said spindle.

2. In combination with a car ot a plurality of car stakes: operatively mounted thereon having. corrugations or serrations in the outer. wall a'chain extending between the said stakes having links engagingiwith the; coinrugations a tubular non-rotatable spindle mounted on-thei can; lockingmem= bers' carr-i'ed by thespindle designed to lock the stakes in position, and a screw designed to; move "the spindle in -a longitudinal direction. i r w 3. Incombination witha: car of pluralit'y of, stakes operativelymounted thereon and arranged in pairs having theirouter wall-corrugated or serrated, means forlooking the stakes in positiom chains engaging with-the stakes-lever means for tightening the chains; a longitudinal extending non rotatable spindle slidably mounted on the can, lockingmeans coacting-with the stakes carried by the; spindle and screw means for actuating the spindle;-

In witness whereoffI have hereuntoset my -hand.
