Broling, Homewood, 111., assignmto Brandon Equipment Company, Chicago, Ill., a corporation of Illinois Filed June 14, 1965, Ser. No. 463,813 8 Claims. (Cl. 105-369) This invention relates to improvements in anchoring devices for anchoring heavy equipment to freight cars and the like and more particularly relates to such devices as may be anchored to the stake pockets of freight cars.

A principal object of the present invention is to provide a simple form of anchoring device for tying down heavy loads, such as tractors and other heavy equipment to the floors of freight cars, by releasably anchoring the tie down chains for the load, to the stake pockets of the car.

Another object of the invention is to provide an improved anchoring device for anchoring tie down chains to the stake pockets of freight cars and the like, in which the anchoring device is insertable into a stake pocket from the top thereof and is provided with a simplified form of locking means freely mounted on the anchoring device to move to a locking position by gravity.

Still another object of the invention is to improve upon the anchoring devices heretofore in use to tie down tractors and other heavy equipment to the decks of freight cars, by providing a simple and improved form of anchoring device in the form of an anchoring block insertable in the stake pocket of the car from the top thereof and having anchoring engagement with the underside of the front wall of the stake pocket, in which the anchoring block is locked in position in the stake pocket by a relea-sable locking member normally moving into a locking position by gravity and releasable from the top of the stake pocket.

These and other objects of the invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawings wherein:

FIGURE 1.is a fragmentary view in side elevation of a portion of one side of a freight car, showing a stake pocket with an anchoring device constructed in accordance with the principles of the invention therein, and an anchoring chain extending therefrom and anchoring a tractor to the car;

FIGURE 2 is a front end view of the anchoring device shown in FIGURE 1; and

FIGURE 3 is a vertical section view taken transversely through a stake pocket and anchoring device' therein, with the tie down chain slack and the anchoring device in a lowermost position in the pocket.

In the embodiment of the invention illustrated in FIG- URE 1 of the drawings, I have shown a freight car having a tractor 11 held in position on a flat deck 12 of the car by a tie down chain 13 anchored to a stake pocket 15 of the car. The freight car 10 has stake pockets 15 secured to and extending outwardly of side frame members 16 of the car at suitable intervals for the length of the car, it being understood that the stake pockets are spaced along the side frame members of the car and open through the flat deck 12 of the car, and that a separate tie down chain may be anchored to each stake pocket, for anchoring tractors or other heavy equipment to the deck of the car.

The stake pockets 15 are of a conventional form and each includes a front wall 17 having a reinforcing lip 18 extending outwardly of the upper end thereof and having parallel spaced

side walls

19, 19 extending therefrom to the side frame member 16 of the car. The

side walls

19, 19 have flanged

feet

20, 20 riveted or otherwise secured 3,331,334- Patented July 18, 1967 to the side frame member of the car. The front wall 17 with the

side walls

19, 19 and frame 16 of the car form an open pocket, opening to the top and bottom of the pocket and forming a retaining or anchoring means for an anchor block 21 having a chain 13 anchored thereto. The anchor block 21 is generally hollow having a top wall 22 extending across the upper ends of parallel spaced side walls 23 connected to and extending rearwardly of a front wall 25, registering with and slidably engaging the inside of the front wall 17 of the stake pocket 15, when the anchor block 21 is in place in its stake pocket, and tension is taken up on the chain 13. A retaining flange 26 extends outwardly of the lower end of the front wall 25 :and normally is under the bottom of the front wall 17 of the stake pocket 15 to retain the anchor block 21 to said stake pocket upon an upwardly pulling force thereon as by the taking up of tension on the chain 13. Spaced retaining lugs 27 extend forwardly of the

side walls

23, 23 and have bottom surfaces in alignment with the top of the front wall 25 to engage the top of the front wall 17 of the stake pocket 15 and retain the anchoring device from falling out of the stake pocket as tension is released from the chain 13, as illustrated in FIGURE 3.

The

side walls

23, 23 are tapered from the top rear end portions thereof toward the front wall 25, as they extend downwardly to the bottom of the anchor block, as shown in FIGURE 3 and indicated by reference character 29. The tapered rear end portions of the side walls 23 accommodate the insertion of the anchoring block into the stake pocket from the top thereof, the taper of said side walls being suflicient to enable the flange 26 and anchor block 21 to fit into the stake pocket from the top thereof and slide downwardly therealong into the position shown in FIGURE 3.

The front wall 25 has a generally keyhole shaped slot 30 leading therethrough and having a neck portion 31 opening to a relatively narrow slot 32 in the bridge or top Wall 22 of the anchoring block, and of a width sufficient to enable a link 33 of the anchoring chain to slide therealong and be held in position in the anchoring block by the next adjacent downwardly spaced link 34 extending at right angles thereto, and abutting the underside of the top wall 22, as tension is taken. up on the chain 13. A bar 35 extends across the widened end portion of the keyhole slot 30 and is welded or otherwise secured thereto, after placing the anchoring chain 13 in the keyhole slot in position within the anchoring block, to prevent unauthorized removal of the chain from the anchoring block.

A locking lever 36 is provided to lock the anchoring block 21 in position in the stake pocket as inserted there- :in. As shown in FIGURE 3 the locking lever 36 is disposed between the

side walls

23, 23 and is pivotally connected therebetween on a transverse pivot pin 37, mounted at its opposite ends in said side walls. The locking lever 36 has an upwardly projecting ear 39 at its outer end having an aperture 40 therein to receive a link 41 of a release chain 42. The chain 42 extends through an opening 43 in the top plate 22 and has a ring 44 on the end thereof of a larger diameter than the size of the opening 43, to retain the chain from falling into the stake pocket, and forming a gripping means for moving the lever 36 into its upwardly extended release position, shown by broken lines in FIGURE 3, accommodating the removal of the anchor block 21 by moving said anchor block angularly inwardly within the stake pocket to clear the flange 26 from the inner side of the front wall 17 and then drawing the anchor block upwardly through the stake pocket.

The locking lever 36 is sufficiently heavy at its outer end that it will drop by gravity into its locking position upon the release of tension on the chain 42, as when the ring 44 is resting on the top surface of the top wall 22.

Downwardly and upwardly extending stop lugs 44 and 45 respectively, are provided to limit movement of the locking lever 36 downwardly beyond a locking position and upwardly beyond a position where it will not return to its locking position by gravity.

The stop lug 44, as shown in FIGURE 3, has an abutment surface 46 extending vertically when the locking lever is in its locking position and engaging a stop rib 47 extending along the inside of the wall 25 adjacent the bottom thereof. The stop 45 is of a similar form and has a wall 48, which is in a vertical position when the locking lever 36 is in its release position and engages the inside of the wall 25 to limit upward movement of the locking lever beyond a position where it will not return by gravity.

In tying down a tractor or other vehicle to the flat deck of a freight car. assuming the anchor blocks are in position in their stake pockets, the anchor blocks will be in their downwardly extended positions as the anchor chain is attached to the tractor or other device it is desired to tie down. As shown in FIGURE 1 the anchor chain has a turnbuckle 50 therein and is extended upwardly over the top of a tread of the tractor 11 and may be hooked or otherwise secured thereto in a conventional manner, the books not being shown herein, since they form no part of the present invention. As tension in the anchoring chain 13 is taken up by turning the turnbuckle 50, the anchor block 21 will be drawn upwardly along the stake pocket to engage the retaining flange 26 under the bottom of the front wall 17 as shown in FIGURE 1 and thereby anchor the anchoring chain 13 to the stake pocket.

FIGURE 1 shows by broken lines the positions the anchoring chain 13 may taken when it is desired the anchoring chain extend angularly toward the front or rear of the tractor, as well as vertically of the anchoring device, to retain a tractor or other device to be anchored to the deck of the flat car from movement along the car. The end anchoring devices on the car may have their anchoring chains inclined in one direction or another with respect to the anchoring blocks, to better hold the device being tied down from a tendency to move along the car.

While I have herein shown and described one form in which the invention may be embodied, it may readily be understood that various variations and modifications in the invention may be attained without departing from the spirit and scope of the novel concepts thereof.
