Specification of Letters Patent.

Patented June 24, 1913.

Application filed March 20, 1913. Serial No. 755,673.

To all whom, it may concern:

Be it known that I, EnwAnn-B. SiiinLos, a citizen of the United States, 'residingat Tacoma, in the countyof lierce andStat'e of \Vashington, have invented a new and useful Imgging-Car Stake, of which the fol lowing is a specification.

This invention relates to stakes to be used on logging and similar cars, and has for its objects to provide a removable extension to the car stake for which I have made applica- 1 tion for Letters Patent of the United States under date March 25th, 1912, Serial No. (586,006. whereby the said stake can be used jects by the device s, mechanisms, and ar-: rangements' illustrated in'the accompanying drawings, in which-f Figure 1 is an elevation of a part ofabunk with a stake mounted thereon in operative position, the car sill. being shown in scction;'Fig. 2 is a side elevation thereof; Fig. 3 is a viewsimilar to Fig. l showng the car stake released andalso indicating the wheel and track in dotted'lines, Fig. 4 is a detail of thestake extensionrin operative position, showing the stake proper in dotted l nes; and Fig. 5 is a similar'view showing the stake proper in the act of dropping and releasing the stake extension; Fig. 6 is a horizontal section of the stake extension; Figs. 7 and 8 are side and front views of the stake proper showin the device'whereby the said stake is held in withdrawn position when not in use; and Fig. 9 is asection of the bunk showing said stake'mounted therein in elevation and illustrating said device in operation; Figs. 10 and 11 are two views showing the latch whereby the compression -'bar of the stake'is kept from being accidentally released.

Similar numerals of reference refer to similar parts throughout the several views.

Referring first to the device for locking the car stake in operative position and illustrated principally in Figs. 10 and 11. The stake 1 is mounted on thebunlt 2 by a pivot 3 passing through the end of the radial arm c'andis upheld in vertical position by the compression bar 5 which is pivoted to the end of the curved arm 6 and which extends across the ear, within the bunk 2 all as described in the said application The bar 5 has a shoulder 7 at the lower edge of its free end, which shoulder engages the cross wall 8 of the bunk thus preventing the for patent.

downward swing of the stake 1 on its pivot 3. Now it is evident that if the .bar 5 were to be accidentally forced upward a sufficient distance toallow the shoulder 7 to become disengaged from the wall 8, thestake would be released and would fall thus dumping the logs from the car, hence I have devised.

the following described latch. The-latch consists of a sector 9, pivoted at its center to the bunk 2'above the wall 8, and engaging the bar 5 and having a handle 10 exten ing down adjacent to the end of the said bar (Fig. 10). \Vhen the circular part of the sector 9 engages the top' of the bar 5'it effectually locks the'bar' against any upward movement. But when it is desired to unlatch the bar, the handle 10 is raised thus turning the sector on its pivot until it allows the bar to be raised by any suitable means (Fig. 11) out of engagement, with the wall 8 thus releasing the stake 1.

Referring now to the friction device illus- 'cation for a patent, but in this position the bar 5 is raised and acts on'lthe said eurved arm]? to turn the stakeon its. pivot 3 to bring the said stake again into nearly ver-" tical position, in which-case a log may hit it and swing it far enough for the shoulder 7 to again engage the wall 8 and thushold it in operative position. To overcome this action I have devised the friction means which is mounted on the stake and which engages the said walls 11 whenthe stake is in released position, thus holding the stake down against. the said action of the bar 5. This device consists of a wire spring 12 mounted in the hollow upper end of the stake l and passing out therefrom through the holes in the sides of the stake to engage the said walls ll. The ends of the wire are preferably turned back through other holes in the stake to the interior thereof; Thus i when the stake swings down the portions of the wire extending out from the sides thereof engage the walls 11 and hold the stake down, yet when it is desiredto use the stake again it can be, easily lifted to place.

Referring now to Figs. 1, 2 and 3. The blink 2 is provided with a pair of ridges 1S extending along it on each side of the center of the curved top, said ridges being adapted to prevent the accidental shifting of the logs longitudinally during transit;

The extension stake, illustrated in Figs. 1 6 inclusive, consists of a metal standard 14, bent substantially as shown in the drawings, to bring its notched foot 15 inward to rest against and be surmorted-hy the upper edge of the bracket plate 16, forming part of tiie;bunlc 2 and positioned beside the top edge of-the outer sill 17-of the car; and to allow the main portion of the standard to be positioned outside of the stake 1. A loop or strap-l8 is secured to the standard 14 and extends inward therefrom, being positioned and proportioned so as to engage the inner vertioal surface of the stake 1 near the top thereof and allowing sufficientspace be tween the stake and the standard to permit the stake to drop therefrom when released and as the standard drops (Fig. 5). A short chain 19 is secured to the lower end 'of the standard 14 and to the bunk 2 (Fig.

2). When theextension stake is not in use it is laid on the deck of the car beside the bunk to which its chain is fastened. When it is in use, however, it is placed with its notched foot 15 in the above described posi tion and the stake 1 is raised to enter the loop or strap 18 to hold the stake up. In this position the stake holds the standard from falling outward under the side pressure of the logs and also from being twisted by any longitudinal strain of the logs bemuse the strap 18 engages the sides of the stake 1. Now when the logs are to be dumped the stakeal is released by raising the end of its bar 5 at the other side ofthe car .from the wall 8' as described in the aforesaid application for patent thus withdrawing the inward-aetlng force from the standard and allowing it to swing outward! and fall, as shown in Fig. 3, and allowing the logs held thereby to be dumped.

Having described my invention, what I claim is 1. In a car stake, the combination with a bunk extending across the car and having a stake guide at one end and a cross wall at the other end; a stake pivoted to said blink and positioned within the stake guide; a compression bar'secur'ed to -said'stake and extending across the ear and engaging the cross wall of the bunk whereby said stake is held in upright position; anda removable latch engaging. the compression bar adjacent to said cross wall and adapted to prevent said bar from moving out of'engagement with said cross wall. V

2. In a car stake, the combination with a stake mounted oh the car and having meanswhereby said stake is releasably held in upright position; of a standard engaging and supported by the car at its lower end; and a strap secured to said standard intermediate its ends and engaging the inner side of said stake, whereby said standard is held from outward movement.

3. In a. car stake, the combination of a standard; the foot of said standard vbeing shaped to engage the upper corner of the car sill to support the standard and to prevent the inward movement of the-foot; and

i-eleasable. means engaging said standard EDWARD B. SHIELDS.
