3 Claims.

My invention relates to improvements in stake holders for railway ilat cars, and the object of the invention is to devise a simple, cheap and quickly operable holder whereby the stakes may be released in a minimum amount of time and with a minimum amount of effort, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

Fig. 1 is a perspective view of a flat car body intermediately broken away of its length and showing my stake holders applied thereto.

Fig. 2 is an enlarged plan sectional view of the stake holder and stake.

Fig. 3 is a plan sectional view through the stake holder on the same scale as Fig. 2 showing the holder in the closed position in full lines and in the open position in dotted lines.

Fig. 4 is a vertical sectional View through the centre of the stake holder.

In the drawing like letters of reference indicate corresponding parts in each figure.

1 indicates the body of a flat car provided with stake holders Secured to the side of the car, these stake holders each comprise a socket member 2 consisting of a back plate portion 2X, from which extend forwardly

upper lug members

3 and 4 and

lower lug members

5 and 6. The

lug members

3 and 4, and 5 and 6 form the side portions 'of the socket between which the stake 7 iits, the lower end of the stake resting, at its inner edge, upon a slightly inward extension 5x as clearly indicated by dotted lines in Fig. 2.

By this means it will be seen that a socket memi ber having an open front is provided. 8 and 9 are jaw members comprising a vertically set bar-like body secured to rods forming end pintles 8X and 9X pivotally mounted respectively in the upper and

lower jaw members

3 and 5, 4 and 6. The v'rear side of the body is formed concentric with the pintles 8X and 9X.

The outer face of the back plate 2 is preferably inclined outwardly from the upper to the lower end of the socket so as to give a corresponding 'inclined pitch to the inserted stake. The body members 8 and 9 of the jaws are provided withinwardly extending upper and lower opposing gripping pieces 10 and 11, preferably situated at the upper and lower ends of the bodies 8 and 9, such pieces extending inwardly at right angles to such body members so that, when they are in the closed position, they bear against the outer face of the stake.

12 are bearings of any suitable form in which "is mounted a longitudinal movable rod 13 having (Cl. 10E-383) an end slot 13X. 14 is a collar secured to the rod 13 and provided with inwardly extending lugs 14X and 14. The pintles 9X are provided with downward extensions having horizontally turned ends l0x and 11X having longitudinal slots 10o 60 and 1lD overlapping one over the other in their locking position.

15 is a link provided with a jawed end, the members of which extend above and below the portions- 10X and 11X and through which and the 65` slots 10 and 11 extends a pin 16. The opposite end of the link 15 is also provided with a jawed end between the members 17X and 17 of which the collar 14 ts, such collar being provided with pintles 17 diametrically set and on 70' which the members 17x and 17 of the link l5 are pivoted. The members 17X and 17o are provided with internal bosses 18 and 19 having semicircular faces bearing against the lugs 14X and 14.

The rod 13 is moved longitudinally by means 751 of a lever 20 having an arm 21 extending through the slot 13X, its movement being limited by the stop 21X. 22 is a locking pin extending through an orifice in the timber 1x in front of the main arm of the lever 20 so as to positively hold the 80' mechanism in the locked position.

When the parts are in the position shown in the drawing with the stake inserted as shown in Fig. 2 the link 15 bearing against the portions 10x and 11X at one end and against the lugs 14X and 14 at the opposite end definitely locks the members 8 and 9 in the locked or stake holding position. When the rod 13 is moved by the lever 20 in the direction of arrow the parts are carried to the dotted position as shown in Fig. 3 and 901 swing the members 8 and 9 to the open position also indicated by dotted lines in Fig. 3 releasing the stake which is then forced out of the socket by the weight of the load.

From this description it will be seen that I have devised a very simple means whereby the stakes of the ilat car may be readily released by a single quick movement of the operator, the load on the side of the car of the released stakes forcing such stakes outward so as to swing the jaw members 8 and 9 to their open position and thereby allowing the stakes to fall clear releasing the load.

What I claim as my invention is:

1. In a stake holder` a socket member comprising a back plate, horizontal upper and lower lugs extending from each side of the back plate and a stake rest extending from the bottom of the back plate, a stake holding member pivoted between each pair of lugs, a longitudinally slidable rod carried in stationary bearings, and means operated by the longitudinal movement of the rod for swinging the stake holding members to and from their stake holding position.

2. In a stake holder, a socket member comprising a back plate, horizontal upper and lower lugs extending from each side of the back plate,

a stake'rest at the bottom of the back plate, a

stake holding member pivoted between each pair of lugs, opposing arms extending transversely of the back plate and carried by such pivoted mem-v bers, a longitudinally movable rod slid-ably mounted in stationary bearings, an operating lever therefor, and means connected to the opposing arms and operated by the longitudinal movement of the rod for swinging the stake holding members to and from their stake holding' position.

3. In a stake holder, a socket member comprising a back plate, horizontal upper and lower lugs extending from each side of the back plate, a stake rest at the bottom of the back plate, aY stake holding member pivoted between each pair of lugs, opposing arms extending transversely of the back plate and carried by such pivoted members, a longitudinally movable rod slidably mounted in vstationary bearings, an 0perating lever therefor, a collar secured to the longitudinally movable rod, and a link pivotally connected to the collar at one end and a pin extending through the opposite end and through the longitudinal slots of the arms of the opposing members.
