LINN, or MORRIS, NEW Yonx, essrsnon 1 THE tmamnemcwme ooaronnrron, or MORRIS, NEW YORK, A CORPORATION or new-roan V Locqine Borlsmnn Application filed February 20, 1930. Serial 12 0 429992, l I
In log transportation, and without regard to the type of vehicle, side stakes are employed to hold thelogs on the vehicle. They are mounted so as to be .removably supported 5 in log-holding position and are associated with means under manual control capableof releasing them to permit the logs to roll off the vehicle. The stakes, when released from log holding position, are capable of swinging movement outwardly and forwardly with relation to the platform of the vehicle; and although it has been proposed to effect the release from the far or clear side in order to avoid thehazard of injury to the operator,
such proposalssufier the disadvantage that where reduced topractice the holding means is not immune to entanglement with the logs,
nor have the stakes been constructed and mounted so that in log discharge position they may yield to an obstruction encountered by the moving vehicle and thus avoid breakage of the stakes. e Objects of the present invention areto provide stake-holding means capable of facile release from the far side or the side of the vehicle opposite the released stakes; to provide stake-holding means which, when the stakeis released, will be held inposition' to avoid any entanglement with the logs as '30 the vehicle is moved; so. to construct and mountthe stakes that, when in release position, they will yield to an obstruction; to provide for adjustment to permit difierent holding positions of the stake for the accom- 3 modation of large logs; to utilize the stakeholding means for directing the weight of the wedge log to make the logload very tight; and to direct the two outside logs towards the center of the load for tightening 40 up the load.
In the accompanying drawing Figure 1 is a plan view, showing asingle bolster or framing strut with stakes, at the respective ends, and holding means embodying my invention.
' Fig. 2 isan end elevation of the same.
Fig. 3 is a side view of a single stake in discharge position and graphically show ing the abilityof the stake to clear 7 p 7 a stump or other obstruction.-
a Fig. .4 is aside viewof the stake invlogholding position: j v j "1 While the number of stakes,v obviously, may vary, the description and showing}, for simplicity, will be confined toa single pair.
A transverse-body framing strut or bol ster I is provided ateach end with a-stake2,
which, save in the details hereinafter noted,
may be of any approved construction. mm bolster 1 is formed at its respective'endswith astake-receivin-g pocket 3, preferably formed by the extension of the'side bracing plates ozt the bolster, but in any event, including side wallsl. The stake has a hinge element Or pivot section '5, more or less snugly fitting between the side walls 4: of the pocket, and
pivotally connected to such side walls by-a bolt 6.- The pivot secti-onis thus capable of swinging .i-n-the longitudinal-planexof the bolster, but in either raised or lowered position is held by the side walls 4 from other movement. The stake'prope'rincludes a-body- 7 of appropriate length," the*lowerend of which provides spaced walls 8, which fitoven the tree end-of the pivot section 5. Aapivot bolt 9 unites the walls -8, and thereby the stalre proper, andthe pivot section 5, the direction of the pivot bolt 9 being, at right angles to that of the pivot bolt 6: Thus the stake proper capable of swinging in a directio'n at rightv angles to the swinging move;
ment of the pivot section, and as the latter moves-in the longitudinal plane of the bolster, the stake-proper will swing at right angles to suchplane,. or longitudinally of the vehiclebody,
The relation of or log-holding position, as shown in Fig; 4, i
the walls 8 thereoffit between the side walls a of the pocket, and the stake proper is held walls 4 of the pocket 7 v 3,and the mounting ofthe pivot section and i I against movement on the pivot bolt 9. Contrariwise,-wl1e11 the stake is inv lowered or log dlscharglng pos1t1on, the l'ow-ervend of the stake proper, that isto say, the walls 8, I are wholly free of the side walls ot'the pocket 3, and thestake proper isfree'to 0 swing in 'a directionlongitudinally of the:
vehicle body, thus yielding in event an r obstruction, which otherwise would tend to break the'stake. This feature is shown more particularly in Fig. 3. r s The outer wall of the stake proper,'a t a convenient point above the bolster,.is integrally formed, or provided with an upwardlyopening hook projection 10, designed to receive and support the holding means." The holding means is in theform of achain or like flexible element 11, terminally'secured at 12 to the side of the bolster, from, whence it extends over the hook-'10 and around the stake proper,'and then through guides13 on the; oppositeside of the bolster, and terminates n'e'arfthe "end of the bolster insev- The holdingfmeans'for the opposite stake l is; similarly arranged, though terminally connected and' guide/din a manner opposed to'that of the first mentionedchain." Near each end of thebolster, and of course on opposite sides, is'mounted a bracket 15, in which is pivotally mounted a lever 16, over 'whichone of the rings 14 of the chain is designed to be passed. The bracket 15 carries a pivotally supportedkeeper 17 to be passed over the'free end of the lever 16, following the placement of the ring 14 and proper.
movementof the lever to put itin the plane of the keeper. A shorthand chain 18 is connected to the keeper, so that the latter 'may be operated-at will in an-obvious manner to release the free endfof the lever l6 inorder to free the connected ring 14 and thereby the particular chain 11. "It. will be notedthat-theholding' lever'16 and com.
plem'entalreleasing means for each particular stake is 'located' on the bolster at the end remote from that stake.
Thus, in releasing the-stakes on one-side of 'thevehicle, the operator will of necessity be on the opposite side of the vehicle and not exposed to falling logs.
Another merit of 1s that on both sides'of thebolster, that is to say,'to the fixedend 12 on one side and to the first guide-'13 on the other side, it presents a more or lesssharpl'y'inclined support, indicated at 19, for the outside logs, so that they tend to roll towards thevc'enter and tightenthe load. Moreover, the manner of.v supporting the chain from the" bolster eliminates the menace of pendant portions catchingorfouling after the released logs.
