CAR STAKEJ Application med August 12.1927. Serial No..212,5 77.

This-invention relates to improvements in car stakes and. more particularly to telescopic car stakes for flatand ,gondola railway cars. I

Tllheprimary-object of the invention is to provide a telescopic car stake which is ex tron-rely simple and durable in construction as'vvell as'eflicient in use.

Another object is to provide animproved telescopic car stake embodying simple and efficient means for releasably maintaining thewsame in: extended condition.

Aafurtherobject; isto provide an improved telescopic caretake of the above kind having simple. and efficient lmeans whereby the load binding chainsmay be readilyadjusted to the heightof theiload.

-Gther objects-willbecome apparent as the nature of the invention is better understood, and the same-consists in the novel form, combinationand arrangement ofparts hereinafteiumore fully describecLwshown in the accompanying-drawings and claimed.

- In the; drawings, wherein like reference characters indicate corresponding parts throughout the several views,

Figure 1 is a fragmentarylongitudinal section of a gondola car equipped with a telescopic stake constructed in accordance with the present invention the stake being in extended condition and shown in side elevation as seen looking toward the inner sides thereof;

Figure Q isafI' agmentarv transverse section taken upon line 2--2 ofFigure 1;

Figure 3v is a vertical section taken upon line 3-8 of Figure 2;

Figure .4 is a view similar to Figure 3 wit-lathe stake. n collapsed condition; and

Figure .is an enlarged horizontal sec tion taken upon line..55 of Figure 1..

Referring more-in detail to the drawings, the present car stakesincludes telescopically associated lower and upper sections 5 and 6. preferably in the nature of open-ended rigidmetallictubes of rectangular cross-section as shown inlFigure 5. whereby relative turning of thesectionsv will be prevented.

The upper'seetion lower section 5 and has pairs of opposed horizontal sliding catch bolts 7 mounted in the lower end portion thereof. As shown. the pairs of catch bolts are mounted in spaced superimposed relation, and the inner ends of the bolts of each pair are operatively connected by toggle links 8, the adjacent 6 slidably fits into the pivotally connected ends of which are pivoted to a-vertical operating rod 9 thatproects upW-ardlyin the upper stake section 6 and terminates near-the upper end of. the

latter in a handle 10. Each pair of latch;

bolts is slidably mounted in a casing ll-suitably fixed within the stake section :6 and enclosing helical tension springs 12 which act to normally project the. latch bolts through the opposite-side ofthe stake section 6. As shown, the inner ends of the latch bolts are-providedwith oppositely proecting lateral extensions 13 towhich the inner ends of the springs 12 are. attached, the outer ends of the springs .12 being suitably attached to the outer ends of the casing 11. In view of .the above construction it will be seen that by pullingupwardly upon the rod 9,-ithe toggle links 8 will be broken in an upward direction so as to effect vthe retraction or release of both pairs of lock ing bolts, while upon releasing the rod 9-,

' the springs .12 -wi1l act to straighten. the

toggle links, lower rod 9 and project bolts 7.

Provided in opposite sides of the lower stake section are pairsof spaced superim posed openings 14 outwardly into which the latch bolts 7 are adapted to be projected when the upper stake section 6 is elevated to extended or operative position. When the bolts 7 are thus projected into the open.- ings 14, it Will be evident that the upper stake section is effectively maintained in its elevated operative position. By employing two pairs of opposed locking bolts in spaced superimposed relation, a most effective latching engagement with the lower section is had and the upper section is effectively braced against lateral strains and accidental release. Any suitable means may be provided for fastening the'stake to the car and for preventing movement of the section 6 entirely-out of section 5. but as this forms no spociticpart of the present invention disclosure thcreof is refrained from herein. Obviously, the stake may be applied to the outer side of the sill of a flatbottom car, but as shown, thesame is mounted at the inner side of the side. wall'14 of a gondola car.

In order to exclude the entrance of dirt and other foreign matter into the stake section to an objectionable degree, the upper end of the upper stake section 6 is preferably closed by means of a hinged cover or cap 15 adapted to be readily opened to fa 18. This load binding chain is adapted to be extended to the slide block 17 of another similar stake mounted upon the opposite side of the car directly opposite the present stake shown, as is generally well known in the art. As the slide blocks are freely slidablo in a vertical direction, it is evident that the load binding chains 18 may be readily adjusted vertically to the height of the load relative to the upper stake section.

In use, assuming that the stake is collapsed as shown in Figure 4, the cover 15 is open and by inserting the fingers into the I upper end of the stake section 6, the handle 10 may be grasped. By pulling upwardly upon the rod 9, the latch bolts 7 may be positively fully retracted so as to offer no frictional resistance whatever to the elevation of the stake section 6. As soon as the stake section 6 reaches its upward limit of movement to operative position, the bolts '7 will be projected by springs 12 into the openings 14, thus effectively sustaining the section 6 in elevated position. The cover 15 is then closed and slide 17 is adjusted to the desired elevation in slots 16. When it is desired to collapsethe stake, the cover 15 is again opened and the rod 9 pulled upwardly so as to release the catch bolts 7, and while exerting an upward pull upon the rod 9, the stake section 6 is forced downwardly into the lower stake section 5 to the position of Figure 4:. As the stake section 6 is slightly longer than the stake section 5, the cover 15 will not interfere with lowering of said stake section 6, and by making the latter slightly longer, the necessity for re moval of slide block 17 may be avoided.

From the foregoing description it is believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

Minor changes may be made without departing from the spirit and scope of the in vention asclaimed.

What I claim as new is 1. A telescopic car stake comprising hollow lower and upper sections slidably fitted one within the other, opposed horizontal sliding latch bolts mounted in the lower por tion of the upper section and engageable with the lower stake sectionto hold the uppersection in extended position, and a vertical pull rod within the upper stake section operable for releasing said latch bolts.

2. A telescopic car stake comprising hollow lower and upper sections slidably fitted one within the other, opposed horizontal sliding latch bolts'mounted in the lower por tion of the upper section and engageable with the lower stake section to hold the upper section in extended position, a' vertical pull rod within the upper stake'section operable for releasing said latch bolts, said pull rod terminating in the upper end of the upper stake section, and a cover for theupper end of the upper stake section, movable to uncover the latter and permit accessto the pull rod.

3. A telescopic car stake comprising hollow lower and upper'sections slidably fitted one within the other, opposed horizontal sliding latch bolts mounted in the lower portion of the upper section and engageable with the lower stake section to hold the up per section in extended position, a vertical pull rod within the upper stake section operable for releasing said latch bolts, and toggle link connections between the inner ends of the latch bolts and said pull rod.

4. A telescopic car stake comprisinghollow lower and upper sections slidably fitted one within the other, means to releasably hold the upper section in extended position,

said upper section having an elongated yer tical slot in the inner side thereof extending substantially from top to bottom of the same, an H-shaped slide block slidably engaging the wall of said upper section at oppositesides of said slot and movable in the latter for vertical adjustment, and a load binding chain attached to said slide block.

5. A telescopic car stake embodying hollow lower and upper sections slidably fitted one within the other, spaced superposed pairs of opposed spring-projected latch, bolts mounted for horiozntal slidingmovement in the lower part of said upper section, a vertical operating rod in said upper section terminating near the top of the latter, and toggle links connecting the inner ends of said latch bolts to said operating rod, the lower section having openings in the upper portion thereof to receive said bolts for holding the upper section in extended position.

In testimony whreeof I aflix my signature.
