BUNK FOR LOGGING-CARS.

Specification of Letters Patent.

Application filed February 13, 1920. Serial No. 358,518.

To allwhomizimaiz concern: j

Be it known that I, JAMES M. MEANY, a

citizen of the United States, and aresident of.

Portland, county of Multnomah, and State of Oregon, have nvented a new anduseful Improvement in Bunks-for Lgg1n'g-Cars,oi'

' which the following-is a specification, the

principle of the invention being herein ex plained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

-As is well known, it is desirable'in handlingylogs onrflat' cars, and in other similar 7 connections, to provide stakes along the sides of the cars in order to prevent the logs from rolling off when stacked up in'a pile. It is of course necessary that such stakes be movable so as to clear the sides of the car when it is desired to roll the logsotf, and in order to secure full capacity in loading the stakes require to be relatively high. In order, however, to adapt a car, equipped with stakes otherwise satisfactory, for use with loading machines .or traveling derricks of the type such as the McGifi'ert loader, which straddle the track when in operation,empty cars being successively advanced through and beneath such loader,stakes of the land in question can neither project upwardly nor depend downwardly without interferingwith such'loader.-

The object of the present-invention, ac-

cordingly, is to provide an improved bunk V or bunker for vloggingcars that has stakes which may be folded up after the fashion of a jack-knife 'when'not .in use, that may be readily dropped'out of the way when unloading, and that otherwise fulfil' the-req'uirements indicated above. "To the accomplish ment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out'i'n the claims, the annexed drawings and the followingv description'setting forth in'detail certain mechanism embodying the invention, such disclosed means constituting, however, but oneof various mechanical forms in which the principle of the invention may be used. i

In said annexed drawings Figure 1 is a front elevation of one form of myimproved bunk,as it appears looking at a car endwise thereof; Fig. 2 is a plan view of the same; Fig.3 is a'sectional view on a somewhatolarger scale of a detail thereof, taken on the plane indicated by the line rails.

of my improved bunk; Fig. 6 is a sectional The car upon which my improved bunk is designed to be installed is not shown, but it will be understoodto be an' ordinary logging or flat car, the bunk inquestion resting on the' floor or deckof'the car. The bunk or bunkerproper comprises two piecesof stand ard railroad iron or rails, whichare securely 7 bolted or otherwise; secured together. in spac'edrelation, as shown in Figs.f2 and 4, a- .Spacing block 2 being interposed for this purpose midway between the ends of said rails. The latterare of suflicient length to overhang the sides. of the; cardeck by the width "of-the brackets 3 which are'respectively secured to "suchsides'and serve to support-the'corresponding extremities of the As shown in F igsh I and 3, these otherwise,"from the track level onto a"car,fit

Will readilyslide past 'thelends of the rails without being caughtjthereby. The brackets 3 also serve to secure the bunkers in place longitudinally of the car deck, there'bein'g at leasttwo, and ordinarily four, bunks employedto a car;

Between the rails 1, immediately adjacent their respective ends, are pivotally secured stakes 5 by means of pins 6 that'pass through such rail ends and the lower ends of such stakes. The stakes are somewhat less in length than half the len'gth of the rails, so as to clear block 2 when they are dropped into; closed or inoperative position between, the

into depending vertical position, as shown rails. The stakes are not only freeto drop into theposition just described, from'their, normal upstanding or operative position, as shown in Fig. 1,}buta1so to swing outwardly,

in Fig. 3,-so as to permit the logs resting. on

the bunker toroll' off. Forthe purpo'se of retaining the stakes against such movement 1'10 outwardly, two chains 7 ,f! are femployed, q- V each being secured at its one end to a ring 8 g V on the side of one of the rails 1, thence passing around the adjacent stake 5 above a projection or shoulder 9 thereon, back' through a ring 10 opposite ring 8, across to and through a second ring 11 at the other end of the bunk, and thence through a suitable hook or notch 12, whereby the free end of the chain is securely held. Uponv releasing such free end of either chain, the corresponding stake 5 will be free to drop outwardly and downwardly, thus clearing the corresponding, side of the car for removal of the logs supported on the bunks.

In order-to retain the stakes against 111- ward turning movement from the upstanding position, in which it has just been indicated the chains 7 are adapted to retain same, I provide means that cooperate with the lower end of each stake to prevent such rotation vwhen desired; In the first constructional form, as shown in Figs; 3 and at, the lower end of the stake is provided with a rather toe, 15,and the pin 6 upon which the stakeis" mounted is formed with an ecce trio 16, so that by rotation of such eccentric the stake end in question may be shifted longitudinally of the rails 1' so as to cause said" toe to engage a ledge 17 formed by the bracket member 4-. Thus, as shown in Fig. 3, the s akemnd has been shifted inwardly to cause the toe 15 to engage with said ledge, but upon rotation of pin 6 in a counterclockwise direction, such end will be shifted outwardly far enough to cause the toe to clear the ledge, as will be readily understood. To" facilitate rotation of the pins 6, they are provided with levers 18, as best shown in 1.

Instead of thus shifting the lower end of the stake so as to engage with the ledge on member 4 or not, as. desired, I may mount the" stake on a fixed pivot pin 20, as shown inj'Figs, 5, 6 and 7, and employ a slidable plate 21in place of the fixed" ledge 17 such plate belng adapted in one position to engage, with'the toe 22 on the stake, and in another'position to clear such toe. In order to adjust the position of plate 21 as desired, I'furtherprovide a rotatable member 23, on

the order of a segmental gear, that has toothed engagement with the plate, said member 23 being mounted. on a shaft 24 journaled in corresponding bracket 4. and

provided with a handle 25 for convenience of operation. 7 a

The general mode of operation of my improved bunker is the same in both forms of construction; thus" when desired to load le s on the] car, the stakes 5 are secured in the r u tandin position by pp p i channel; Qf the ceeli r c p 6 or ofrhe plate 21 so as'toprevent inward rotative movement ofjsaid stakes, while the chains 7 are p around the projections 9011 said stakes he rr ren i h m 9 3 in ngthe car.

lip, or

wardly. l Vhen it comes to unloading, as previously explained, one or the other of the chains 7 is released so as to allow the corresponding stake thus to swing outwardly. WVhen the stakes are not in use they are swung inwardly so as to fold up like the blades of a jack-knife between the rails composing the bunker, in which position they are entirely out of the way and cannot interfere with the loading machine or any other obstruction adjacent the track.

I By reason of: my improved construction, stakes substantially equal-toihalf the width of the car may be employed, which is much longer than has heretofore been. found practicable. At the same time a very strong and substantial mounting for the stake is provided, reducing to a minimum the danger of logs unintentionally rolling from Other modes of applying the principle of my invention may be employed instead of the ones explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed,

I therefore particularly point out and distinctly claim as my invention':--

1. In mechanism of the character described, the combination of a suitable bunker, a stake pivotally attached to said bunker adjacent one end thereof, said stake being normally freely rotatable from an up standing position outwardly about its axis to depend vertically from saidbunker or inwardly to a horizontal position as desired,

and a member on said bunker, said member and stake being relatively shiftable in a horizontal direction to interenga'ge and'thus prevent inward rotation ofsaid stake beyond such upstanding position. i

In nieclianism' of the character de 7. scribed, the combination of a suitable to prevent inward rotation thereof beyond such upstanding position. I I

3. In mechanism of the character described, the combination of a rail forming a V bunker, a stake'pivotally attached to said rail ad acent one end thereof, said stake be ing normally freelynrotatable from an upstandingypositmn outwardly about its axis to depend vertically from saidfrail or inwardly to lie alongside the same as desired,

a toe on the lower end of said stake, and a plate shdable along said rail and adapte'd'to engage said toe and thus prevent inward rotation of said stake beyond such upstanding position.

4. In mechanism of the character described, the combination of a rail forminga bunker, a stake pivotally attached to said rail adjacent one end thereof, said stake being normally freely rotatable from an upstanding position outwardly about its axis to depend vertically from said rail or in- 10 Wardly to lie alongside the same as desired,

atoe on the lower end of saidstake, a plate 7 slidable along said rail and adapted to en- 7 gage said toe and thus prevent inward rotation of said stake beyond such upstanding Signedby me this 7th day of liebruary.
