My invention relates to improven'ients in high stake car bunks ol the lorm that are adapted 'lior fuse on logging c ars or logging `trucks and the object ot my invention is to provide a high stake oar bunk in which the bottoms of the stakes are releasably supported by means that is adapted to be re leased or tripped from the side of the car opposite to the one on which the stake is located. y

Another object is to provide etlicient and easily operated stake holding means, said means including a slidably mounted stake pocket adapted to be closed when it is drawn into thel end of the bunk to receive and hold the bottom end oi ya stake and tol be opened by pressure against the stake when the pocket is moved outwardly in the bunk to release the bottom end of the stake.

Further objects are to provide a high stake car bunk of this nature that is made up chiefly ol standard beams and sections.

l(Ether and more specific objects will be apparent from the following description taken in connection with the accompanying drawings.

1n hauling logs, piling, poles, timbers and the like on flat cars or trucks it becomes necessary to provide upright stakes at the sides of the cars to hold the load* The top ends o'ithe'se stakes are ordinarily secured together by chains or cables and the bottom ends of the same are secured to the cars. The present invention provides transverse bunks for carrying the load and further provides releasable means at the ends of the bunks for the reception of the bottom ends of the stakes.

In the accompanying drawings Figure 1 is a plan view, with `parts broken away, of a high stake car bunk constructed. in accordance` with my inventiom the stakes being removed. H y

Fig. 2 is a side elevation of the same showing both the stakes in place but showing the upper ends of said stakes broken away.

Fig. .6 is a detached fragmentary isometric vie-woll a detail of the invention.

Referring to the drawings, throughout which like reference.numerals designate like parts l show a car stake bunk in which the supporting structure comprises anA Lbeam 10 supported. in a normally horizontal plane by means including cross timbers .11, 12, 13 and 14. that support the medial part of the I-beam 10 and angle bars 15 .and channel shaped members 16' that support the respective ends of the I-beam 10. The cross timbers 12 and 13 litinside of the side flanges ot the I-bea'm 10 and the timbers 11 and 14 lare disposed on` the outer sides of the timbers 12 and 18 respectively and are rigidly secured thereto by bolts 17 so as to :term` a broad and substantial base or support for the medial port-ion of said I-beam as shown in Figs. 1 and 5. ,y

The .angle bars 15 are disposed on the outer sides ot .the I-beam 10 and have their horizontal flanges directed .outwardly to form base supports ot' equal. width 'with' the timbers 11 and 14. Braces 15 are Lprovided at the outer ends oly angle bars 15. The channel. shaped members 16 are disposed inside offthe angle bars 15 and have their 'upright flanges inclined inwardly at the top edge as at 187 and formed, as shown in Fig. it,` so as to receive the side flanges of the I-beam 10. Rivets 19 secure the channel shaped .members 165 I-beam l10v and angle bars 15 together. The channel shaped members 16 are provided toward their inner ends with shelf 'like portions 20, Fig. 6, which are slotted as at 21 for the reception kof operating Vbars 22 and 23, said shelf like portions allording shoulders 24. againstwhich integral. blocks 25 on the operating bars are in locked position and said shelf like portions further having stop lugsQG, Fig. 1 at their inner ends arranged to be engaged by the blocks 25 to limit the endwi'se .movement of the operating bars -when they are in releasing position.

The bunk 1s adapted to rest upon and be secured to' a car or truck bed 27 as shown by broken lines in Fig. 2. The ends of the angle bars 15 'may 'overhang kor project beyond the sides of the car and said .ends vhave plates 28 extendingacross the bottoms thereot and rigidly secured theret'o5 the plates 28 serving as transverse tie members between the two angle bars at each end et the bunk and also serving as supports on which upright stakes 30 and stake holding devices may rest.

r1`he stake holding devices consist of stake pockets 31 each having an opening` 32 ot rectangular shape closed on three sides by integral walls and provided at its outer open end with Lshaped stake holdingdogs 33 that are pivotally secured to the stake pockets 31 by pivot pins 34. The stake pockets 31 rest on the plates 23 and are slidable within they rectangular receptacles formed jointly by the plates 28 and attached angle bars 15. One o' the stake pockets may be provided at. each end of the bunk. `iVhen a stake pocket is drawn into the end of the bunk shown at the lett end, Figs. 1 and 3. the L-shaped dogs will be forced inwardly by the bars 15 so as to cooperate with the stake pocket in 'forming a rectanzguiar receptacle for holding the bottom end of a stake. lVhen a stake pocket 31 is moved outwardly as shown at the right in Figs. 1 and 3 then the L-shaped dogs 33 are clear of the angle bars 15 and are free to swing sidewise, as shown, so as to release the bot-- tom end of the stake.

The stake pockets 31 at each end are provided on their inner or rear sides with lugs 35 to which the ends of the respective op* cratino;

bars

22 and 23 are secured as by pivot pins 36. Each

operating bar

22 and 23 extends longitudinally within the bunk across the car so that the locking end ot each operating` bar will be on the opposite side of the car Jfrom the stake pocket which said bar controls or operates. This makes it possible for a person to stand on one side of a car and release the stake or stakes 30 on the opposite side of the car.

The locking end of each opera-

ting bar

22 and 23 is provided with an integral block 25 affording shoulders that are adapted to lock against the shoulders 24 of the channel members 16. The locking ends of the

operating bars

22 and 23 are adapted to drop into the slots 21 in the shelf portions 2O when the stake pockets 31 are in the holding position. see right end Fig. 3, and to be raised out of said slots 21 when the stake pockets are in the releasing' position, see lett end Figs. 1

and 3. ln the released position the blocks 25 on the

opera ting bars

22 and 23 engage with the stop lugs 2G thereby limiting the movement of said operatingr bars and the attached stake pockets.

Integral guide portions 391 are provided below the blocks 25, said guide portions always remaining within the slots 21 and preventing sidewise displacement of the ends ot the bars when said bars are in the released position.

lnclined guides e0 on the channel members ,eeaeae 16 serve to deflect the locking ends et the operating bars forward when they are moved trom locked to released position thus preventingv said barsv from locking in the slots 21 when said bars are released. The bars are held in the locked position by locking` dogs 11 that are secured to pivots 412 which are journaled in the bunk frame. External to the bunk frame, the pivots 12 have combined weight arms and releasing levers 43 Secured thereto, the weight arms 42) normally serve to hold the locking' dogs l11 in the engaged position but may be moved by an operator to release the lockingdogs.

The operating bars 22 and 23 are released from the locked position by releasing` levers llllot substantially l. shape each having one portion extending along the side of the bunk and the other portion extendingr Crosswise through the bunk and supported for oscillation therein, said last named portions eX- tending under the ends of the operating` bars 21 and 22 and having;v crank elements 45 that engage with the portions 39 of the locking ends of said operating bars to li `ft and release the same when the outer ends of the releasing levers are raised.

rl`he stake pockets 31 have top and bot-tom portions 50 above and below the lugs 35. The top portions 50 are slidable underneath the edges 51 of the top I-beam and the bottom portions are slidable on the bottoms 52 oit the member 16. An opening 53 is provided in the bottom of each member 16 through which dirt and refuse may discharge.

The operation of this high stake bunk is Cil as follows: The bunk is installed on a car or truck as shown in Fig. 2. The stake pockets 31 are drawn or pushed inwardly as shown at the left in Figs. 1 and 3 and are locked in this retracted position by the locking` moans at the opposite ends or the operating levers. The bot-tom ends oiE the stakes 30 are placed in the stake pockets.y the load being placed on the bunks between the stakes. The top portions of the two stakes at opposite ends of the bunk are secured together by a chain or cable, not shown, which passes over the load. The stakes thus serve to hold the load on the bunk. When the car is to be unloaded thc bottom of the stake at one end ci thc bunk is released by a person at the other end oit the bunk by iirst `grasping and turning' the weight arm 4:3 to thereby disengage the locking dog' 41. then lifting' the end ot the releasinglever 44 to disengage the block 37 ot the operating

bar

22 or 23 from the shoulders 2li thus permitting the stake pocket 31 that is connected with said operating bar to move outwardly and allo'wf ing the L-shaped dogs 33 to assume the po sition shown at the right in Figs. 1 and 3 and release the stake. The stake pockets may be pushed back into the bunks from nece,

the releasing to the holding position preparatory to, or in the operation of inserting and setting up the stakes, the end of the operating bar remote from the stake pocket to which it is secured automatically dropping into locked position.

This bunk is strong and simple in construction and etlicient in operation; the stake pockets are relatively deep so that the stakes will not be accidentally disengaged therefrom; the locking means is positive and can not accidentally release, and the stakes are arranged to be tripped from the opposite side of the car thereby eliminating the danger of the operator being injured by the discharging load when he releases the stakes.

It will be obvious that a shortl or long stake may be used as desired and that a bunk may be made having a stake pocket on one side of the car only without depart-ing from the spirit of my invention.
