STAKE-I-IOLDEB.

T o all whom it may concern:

Be it known that I, ARTHUR J. Bos'rwiox, of Eau Claire, `Eau Claire county, VVisconsin, have invented certain new and useful Improvements in Stake-Holders, of which the following is a specification.

My invention relates to stake holders for use on railway cars and logging sleighs and the object of the invention is to simplify and improve the locking and releasing mechanism employed with the device shown and described in my pending application filed June 19, 1909, Serial No. 503,153.

My invention consists generally in various constructions and combinations, all as hereinafter described and pointed out in the claims.

In the accompanying drawings forming a part of this specification, Figure 1 is a perspective view showing a portion of a car sill and the application of my invention there? to, Fig. 2 is a side view, partially in section, showing the arrangement of the locking mechanism and the construction of the holder, Fig. 3 is a transverse sectional view through the sill on the section line ficof Fig. 2.

In the drawing, 2 represents the car sill, 3 a holder having two open sides and flanges 4L and 5, by means of which the holder is rigidly bolted to one side of the sill.

6 is an 'eye provided on the holder wherein a link 7 is pivoted and adapted to extend across one open side of the holder, closing it against a premature discharge of the stake. The second link S is pivotally connected with the first one and extends across the other open side of t-he holder and is pivotally connected with a latch 9, that is adapted to bear on the face of one flange on the holder and has a tapered socket 10 to receive a correspondingly tapered head 11 that is provided on the outer end of a rivet carried by the holder flange and by an angle strengthening plate 12 which is bolted to the sill and riveted to the iange 5 of the holder. The free end of the latch 9 extends into the angle formed by the plate 12 and a pawl 13 is pivoted at 14 on said plate and is angular m form and has a Hat surface 15 that is adapted to bear on the end of the latch 9 and hold it in locking engagement with the taper head 11.

The pawl 13 is arranged to drop by gravity out of Contact with the locking latch and Specification of Letters Patent.

Application led September 23, 1909.

Patented May 31, 1910.

serial No. 519,259.

for the purpose of holding it in its locking position I provide a block 16 pivoted at 17 and operated from the opposite side of the car by means of a bar 18 which is arranged parallel with and near the car sill. The block 17 has a surface 18 that is adapted to engage the edge 19 on the pawl 13 and temporarily hold it in its elevated locking position as indicated in Fig. 1. The end of the that upon the disengagement of the blockI 16 from the locking pawl that the latter will drop away from the latch and the pressure on the stake and load on the bridle will instantly disengage the latch and release the bridle.

I claim as my invention:

1. A. stake holder open on two sides, a bridle pivoted at one side of said stake holder and arranged to extend across said open sides, a locking latch having a socket therein, a head provided on said holder and adapted to enter said socket and means preventing the premature disengagement of said latch and head.

2. The combination, with a car sill, of a stake holder composed of flanges arranged substantially at right angles to one another, one of said flanges being secured to said sill and the other projecting therefrom substantially at right angles thereto, said anges forming a box or holder with two open sides, a bridle arranged to extend across said open sides, a locking latch pivotally connected to said bridle and arranged to bear on one side of one of said flanges, a pawl arranged to engage said latch and hold it in its locking position, and means engaging the end of said pawl and preventing its premature disengagement from said latch.

3. The combination, with a car sill, of a stake holder composed of anges arranged substantially at right angles to one another, one of said flanges being secured to the side of said sill and the other range nrojecting outwardly therefrom, said ilanges rorining a box open on tWo sides, a pivoted bridle arranged to extend across the open sides of said box, a. latch pivotally connected with said bridle and arranged to bear on said outwardly extending flange, an angular pawl pivoted on said sill and arranged to engage the end of said latch and hold it in its loci;- ing position, and ineans operable from the opposite side et the car for holding said angular paWl in engagement *with said latch.

4. rl"he combination, with a car sill.,1 ot a stake holder composed of angularly arranged plates, one of Which is secured to said sill 7 the other plate projecting` outwardly the Lully@- roni, said plates depending belenT the err sill and forming comparatively long be ing surfaces for the stake. a pivoted b arranged to extend aci he openi tween said angle plates, a latch Connected with said bridle an1 bear on one side of said outwardly ing flange and having a socket7 a head mounted on said outwardlyT extending liange and adapted 'to enter said socket, ineans for holding' said latch in its locking position and ineans operable from the opposite side of the car or locking said holding ineans.

o. A stake holder composed of angularly in Witness "whereof, l have hereunto set iny hand this 20th 2y of SeL 1909.
