STAKE FOR CARS.

Specification of Letters Patent.

' Application filed November 18, 1908.

Patented Sept. 26, 1911. Serial No. 463,322.

To all whom it may concern:

Be it known that I, Join: A. citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Stakes for Cars; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and. to the letters of TOOMEY, a

reference marked thereon, which form a part of this specification.

This application relates to stakes for cars of that class known as logging cars, and on which the logs, extending longitudinally the car and held from movement by the stakes, can be rolled from the car only when the stakes are removed or depressed. I-Ieretofore cars of this class have usually been provided with temporary stakes of wood, which are inserted in the stake pockets and when it is desired to unload the car,

are removed or chopped off to permit the logs to be rolled from the deck.

The object of this invention is to afford a car stake adapted to be secured on the sides of a car provided with a locking means whereby the stake is normally held in an upright position, and also provided with mechanism connected with all of the stakes on the same side of the car adapted to simultaneously unlock or release the stakes.

It is also an object of the invention to afford a car equipped with stakes adapted to normally look when in upright position and connected by means permitting all the stakes on one side of the car to be simultaneously and automatically released to discharge the load thereover.

It is the further object of the invention to afford a logging car having adjustable stakes thereon, said stakes being physically connected by a mechanism adapted when actuated to release all the stakes on that side of the car and to provide in connection therewith a trigger adapted to actuate the release mechanism by engagement with a third rail placed alongside of the track.

It is a further object of the invention to provide in connection with the car provided with stakes such as described, a tipple adapted to incline the deck of the car at an angle sufliciently to cause the logs to roll therefrom when the stakes are released and provided in connection therewith with suitable means for releasing all the stakes on one side of the car.

The invention embraces many novel features and consists of the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a side elevation of a device embodying my invention showing the car upon the tipple. Fig. 2 is an enlarged central section of a device embodying my invention, showing the same with the stakes locked. Fig. 3 is a similar view showing the car upon the tipple and the stakes upon the lower side of the car released. Fig. 4 is an enlarged fragmentary front elevation of the stake and the locking and adjusting means therefor. Fig. 5 is a section taken on line 5-5 of Fig. 4. Fig. 6 is a section taken on line 6-6 of Fig. 4. Fig. 7 is a section taken on line 7--7 of Fig. 4.

As shown in the drawings: A, indicates the side sill of a car of the usual type ordinarily used for logging purposes, and constructed in any suitable manner for the purpose of supporting logs or the like on the deck or platform thereof. Said car, as shown, is provided with stakes, as shown four in number, on each side, although, of course, a greater number may be employed, if desired, said stakes being adapted to be released in discharging the load. Each of said stakes, as shown, comprises the stake and the locking and releasing mechanism therefor, said locking mechanism affording the means for securing the stake to the car side, and serving in lieu of a stake pocket. Said locking mechanism, as shown, comprises first a casting or forging of metal adapted to be rigidly bolted to the car sill, and comprising a plate B, which extends downwardly alongside of the outer face of the sill and horizontally outward therefrom, as indicated by 6, below the sill and from the outer edge, said outwardly turned portion of the casting or forging having in each side thereof, and integral with the outer downwardly extending portion 6, semi-eylindric casings b one on each side thereof and opening inwardly. integrally secured on the sill plate B, and affording part of said casting or fitting, is a conical projection 6, adapted to afford a self-fitting journal for a locking cam C. Said locking cam, as shown, is provided with a central hub a, bored to fit on said bearing projection 6 and is retained in place thereon by means of a pivot bolt 0, which extends therethrough and through the sill and also through a back plate 0 bolted on the inner side of the sill and extending downwardly beneath the same, and provided with an outwardly turned flange 0*, which bears against the sill plate B, on the rear side thereof, and below the sill. Said casting or sill plate is also provided on each side thereof near the top with integral, outwardly projecting flanges D, through which extends the pintle or shaft 65, on which the stake E, is pivotally engaged. Said stake may be of any suitable structural form to afford strength with comparatively light weight, and is provided on the front side thereof at its lower end with knuckles e, which extend outwardly beyond the center of the stake and through which the pintle cl, extends. Said stake is also provided at its lower end with bracket arms 6, one on each side thereof, which extend laterally and outwardly from the stake, as shown in Figs. 4 and 7, and are provided with gudgeons 6 extending longitudinally of the car and in alinement, on which are j ournaled the upper ends of links 6 which are convex on the inner side or that adjacent the sill, and concave on the outer. At their lower ends, said links pivot-ally engage the eye f, in the upper end of the tension rod F, one of which lies on each of the cylindric casings on each side of the sill plate. As shown, said tension rods extend through a transverse web or head at the upper end of each casing, and at their lower end extend through a connecting bar f and are engaged thereto by suitable nuts f as shown in Figs. 4:, 6 and 7. A strong coiled spring f is engaged on each rod and bears against the web or head f, and against the connecting bar f and serves at all times to force said rods downwardly, thereby throwing the stake to upright position, as shown in Fig. 7 Pivotally engaged on brackets D, which extend from the sill plate forwardly upon the outer side of each arm 6, of the stake, and provided with an aperture for the pintle d, which extends therethrough, is a dog or latch comprising a tail 9, which extends downwardly below the cam or locking plate and a head G, which extends upwardly beneath the lower end of the stake and is adapted to engage the outwardly engaging lip E, thereon, as shown in Fig. 6.

Secured on the locking cam C, near the periphery thereof, and on the lower side is an inclined face or web 0 adapted when the cam plate is rotated in one direction to en gage the tail 9, and force the same into engagement with a lip or shoulder E, on the stake and when rotated in the opposite direction acts to release said tail and permit the dog to release said lip, as shown in dotted lines in Fig. 6. As shown, the dog head G, when in position to engage the lip, ex-

tends inwardly from the pivot sufficiently that upward draft thereon by the stake occasioned by the outward pressure on the top of the stake, serves to release the latch when the tail of the latch is free to move inwardly.

Means are provided for automatically rotating all the cam or looking plates on the same side of the car simultaneously to release all the stakes, and also to return and lock the same in normal position after the stakes have been released. For this purpose, as shown, the pivot bolt 0, extends beyond the back sill plate 0 and pivoted thereon is a lever H, one for each of the middle stakes. Said lever, as shown, is bent at its middle toward the adjacent end of the car and on the inner or concave side of the same is provided at its middle with an integral arm it, provided at its end witha weight h. At the lower end of each of said levers is provided a roller or wheel 7L2. Bolted on said lever on the outer side thereof, is a curved. arm h which curves inwardly and upwardly through a slot in the lower horizontal portion of the sill plate 6, and is rigidly secured to the cam or looking plate, and may be integral therewith, if preferred.

On the rear side of the looking or cam plate, are provided crank pins 0 one above and the other below the center thereof, as shown in Figs. 4, .6, and 7, and pivotally engaged on each of the same are connecting bars KK, each provided at the end with an adjusting nut 70, adapted to engage the threaded ends of the connecting rods 7c-lt extending from the outer ends of the connecting bars K-K, to the inner ends of the connecting bars K K on the front or rear stake mechanism, and as shown, cross rods lc 7c connect the inner end of each of the upper connecting bars of one of the middle stake mechanisms with the end of the lower connecting bar of the adjacent middle stake mechanism, thus crossing said rods, and of necessity causing the locking plates at one end of the car to rotate oppositely from the locking or cam plates at the other end, and consequently the inclined webs or cams on said plates which engage the tail with the dog, are inclined oppositely, the inclination in each instance being toward the middle of the car.

The operation is as follows: The car preferably is unloaded upon the tipple, as shown in Fig. 3, in which the outer track rail X, is elevated sufliciently above the inner track rail X, to cause the logs to roll from the car when the stake on the lower side of the car is released, and, for releasing said stakes a third rail X is provided on said lower side of' the car and inclining upwardly at the one end to permit one of the rollers if, of the actuating levers to engage the same,

as shown in Figs. 1, 2, and 3. As the car sitely from those at the other, thus releasing the tails of all of the locking dogs at the same moment. The tail of the locking dog is now permitted to swing inwardly instantly releasing the stake, and permitting the same to swing outwardly under pressure of the logs against the same, thus putting the springs f, under tension, as shown in dotted lines in Fig. 6, by drawing the links 7, upwardly over the pintle (Z. When the car is unloaded after the last log has rolled from the car, the tension of said springs tends to throw the stakes to upright position and simultaneously the weight 12/, tends to swing the lever h, downwardly to the position shown in Figs. 1 and 4;, thus again forcing the head of the do inwardly into engaging position and locking the stake in place.

Of course, the stake may be of any desired length or other dimensions and numerous details'of construction may be varied without departing from the principles of this invention, and, of course too, while the invention is described with reference to logging cars, stakes of the class described may be employed in connection with cars used for any other purpose, if desired, without departing from the principles of this invention.
