BOLSTER-STAKE HOLDER.

Specification of Letters Patent.

Patented Nov. 4,1913.

Application filed April 11, 1913. Serial No. 760,456.

To all whom it may concern:

Be it known that I, CASPER FAUs'r, a citizen of the United States, and resident of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Bolster- Stake Holders; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention refers to releasable holders for bolster stakes, its object being toprovide a simple, economical and efiective holder of this type, which holder, when locked, cannot be released except by a manual operation, the said holder being so constructed and arranged as to eliminate springs or other delicate mechanism which might be inadvertently disordered by the severe uses to which appliances of the above general type are put.

Another objectof myinvention is to provide means in connection with the stakes, whereby when they are released from their holders they will remain. suspended from the carrier, this feature being particularly desirable in instances where the load of the carrier is discharged upon trestles or into side pits.

The invention is particularly adapted for use in connection with flat cars for retaining and releasing loads of logs or analogous freight, it being understood that the apparatus is applicable to any type of freightcarrying vehicle, the general idea being to provide means for releasing the stakes upon that side of the carrier from which the load is to be discharged, whereby the danger to the operator of receiving injury from the sliding load is eliminated.

' With the above objects in view the invention onsists in certain peculiarities of construction and combination of parts as hereinafter set forth with reference to the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a cross-sectional view of the body portion of a carrier equipped with a set of bolsterstake holders embodying the features of my invention, and Fig. 2, a'plan View of the same with the stakes in section as indicated by line 22 of Fig. 1.

Referring by characters to the drawings, 1 represents the floor of a freight-car or other carrier having secured thereto a sill 2, it being understood that two or more of such sills equipped with stakes and holders in accordance with my invention are applied to the car or carrier throughout its length and upon which sills the logs constituting the load are piled. Secured to the same side of the sill adjacent to its ends are capplates 3, 3, the same being held in position by bolts 4, 4, which pass through the sills and also secure a second set of cap-plateso, 5, which cap-plates terminate just back of the sill ends with knuckle-members for the reception of pintle-bolts 6 that have hinged thereto circular jaw-clips 8 and 8, the said j aw-clips being extended beyond the ends of the sill and are curved inwardly to form semi-pockets These hinged jaw-clips 8 are arranged to articulate with corresponding fixed jaw-clips 9 which latter project from the clip-plates 3 and are also curved inwardly, being so positioned that when the hinged j aw-clips 8 are closed each pair forms a stake-pocket in conjunction with the end of the sill to which they are attached. Fitted into each pocket is a stake 10 that is provided with a shouldered shank, which shoulder is fitted with a rub-plate 11 that is adapted to rest upon the upper face of the sill in order to relieve the load strain from the stake-holding pockets, the said stakes are connected intermediate of their ends by a chain or cable constituting a runner 12, the

ends of which runner are looped over hooks 13 that extend from the inner faces of the stakes, their ends being upwardly inclined as shown. By this arrangement after the load has reached approximately the level of the hooks the runner is inserted in position and the remainder of the load is piled over said chain or runner. Thus the weight of that portion of the load upon the chain stretch 12 will have the effect of contracting the stakes at their upper ends. The load is further sustained and held in place by a binding chain or cable 14 which constitutes a runner and encircles the top layer of logs transversely. This runner is provided with end loops which engage hooks 15 that project from the outer face of the stakes adjacent to their head ends, the said hooks being provided with open ends that extend clownwardly. Each cap-plate 8 has projecting therefrom a pair of apertured cleats 16, 17 and extending from the free ends of the hinged aw clips 8 are lugs 18 having hooked ends for the reception of lock and release chains 19, 20. The end links of these chains, after being inserted over the hooked nose of the jaw-clip lugs are secured by cotter-pins 20, which pass through the apertures that are formed in said lugs, by which construction the chain-fastening is insured the cleat 17v of the opposite cap-plate and hence the chain so stretched. is locked at two points, being held in its locked position by pins 21, 21, which are fitted through apertures in said cleats. As shown, the pair of locking cleats 16 and 17which carry the chain 19 have sides correspondingly sloped in the direction of strip of the chain therefrom. Hence after the pins 21 and 21 have been removed a slight whip of the'chain will cause its links to strip from the pair of cleats and thus the jaw-clip will be free to swing open. The opposite stake-holder, which is shown in Fig. 2 in its open position, is locked and released in a similar manner from that side of the carrier opposite its position. The locking chains or runners in this instance are shown crossed upon the same side of the sill, but it is understood that in some instances the chains may be connected to the cleats in parallel relations, but if crossed, as shown, should it be desired to release the chain of that stake which is between: the face of the sill and the other chain the position of the chains can be reversed, that is, before the inner chain is released the outer chain can be shifted from one of its locking cleats to effect said release. It will also be observed that I have provided the cap-plates with inwardly projecting rub-flanges upon the face of the sill to prevent wear of said sill and in practice the hinge jaw members are set upon slightly lower planes than the fixed jaw members, by which arrangement when the logs are discharged the strain will come entirely upon said fixed jaw-clips.

It has also been found in practice that when the stakes are released and also when the latter are seated within their holders that their shoulder portions are liable to wear by abrasion or through other causes and hence in order to overcome this feature the shouldered metallic rub-plates 11 are utilized. Hence the wear at this point is eliminated and owing to the metallic contact the stakes are capable of sliding more readily from their holders in a releasing operation. Attention is also called to the fact that owing to the arrangement whereby the chain runners are locked at both ends of the sill that there is no liability of the holders being released except through a positive manual operation, in which case the cotter-pin acent to that holder which is to be released is first removed and thereafter the operatorpasses to the opposite side .of the carrier and releases the last locking means in a safe position relative to the discharge of the load. It should also be understood that while I have shown a peculiar attaching lug for the jaw-clips and end links of the chains that, in some 1nstance, a r vet or any other means may be employed for effecting the desired result.

From the foregoing description it is alsomanifest that when the stake-holders are released for discharging the load that said stakes will be thrown out from their bottom ends by the weight of the load and as the load drags therefrom under while the chains 512 will be released from their hooks 13, the

said stakes will be held in suspension due to the chain connections 14, which chain connections will not free the head ends of the stakes, owing to the fact that the hooks 15 which retain the chains have their noses extending 111. a downwardly direction.

is also apparent that while I have shown the entire stretch of the chains of a single gage that the releasing stretch between the locking cleats may be of much smaller gage than the loop portion which in practice will take the strain of the load.

Attention is also called to the fact that owing to the peculiar arrangement of retaining chains let that when the-load of logs is released the stakes will ride over said logs as they flow from the carrier and thus-be held from entanglement within the logs, while at the same time the stakes are held against dropping to a position between the car, roadway or skidway, whereby. they would cause a jam of the logs and prevent free discharge thereof upon the said roadway or skidway, and, furthermore, should the stakes assume such position the load of logs crowding thereon would have a tendency to break or otherwise seriously damage the stages. These features have all been demonstrated in practice in the operation of releasablefstake holders and are therefore an essential element of my invention.

It will'be readily understood that this dividable stake holder will form a pocket which,in practice, has the function of hold ing a stake as rigidly as a solid pocket.
