LOAD SECURING DEVICE 2 sheets sheei 2 Filed March 1. 1929 INVENTORS GEO RGE C. FEDDERMAN GEORGE W. MARLIN BY 2 QQ ATTORN EY Patented Aug. 4, 1931 UNITED STATES PATENT OFFICE GEORGE C. FEDDERMAN AND GEORGE W. MARLIN, OF DETROIT, MICHIGAN; SAID MARLIN ASSIGNOR TO SAID FEDIDERMAN LOAD SECURING DEVICE Application filed March 1, 1929. Serial No. 343,617.

This invention relates to a device for facilitating the transportation 'of vehicles such as automobiles or the like in freight cars.

In this art it is common practice to provide means temporarily attached to the car floor which may be secured to a part of the vehicle being shipped, to hold the same during transit, but as a rule these devices have been found to be very unsatisfactory for the reason that they are designed for single use. As a result, nails have been relied on to attach the device to the car floor, and after a few ship ments, the car floor is so severely mutilated by repeated driving and drawing of the nails that the use of this type of device has become a real problem, particularly to the railroad companles.

Other devices have been suggested which were designed to be more or less permanently made a part of the floor, but for the most part they have not been practical due to their complicated mechanism and the cost incident to their manufacture.

This present invention, therefore, is concerned with a device embodying all of the advantages of those heretofore used or suggested with none of their disadvantages.

To this end the device of this invention consists of a rail fixed on'top of or below a 3 car floor, and carrying two slidable feet thereon and interlocked therewith. Means are provided for securing each foot to the rail at any one of a plurality of desired points.

Each foot carries a leg pivoted thereto with a fixture at the end thereof for engaging a part of the vehicle to be transported, such as the axle, spring or the like. One of the legs is of a rigid nature but is provided 40 with means whereby its length may be adjusted to suit the circumstances. The other leg is telescopic, with a compression spring rubber orother cushioning element therein, and is. provided with means for limiting'the outward thrust thereof. Either or both feet may beprovided with a finger extension engaging the locking means so that when the legs are in the raised or operative position the finger will prevent accidental displacement in relation to the rail.

In the preferred form, the rail is sunk below the level of the car floor and is contained within a casing having a lid, so that when the device is not in use the legs may be folded down into the casing and the lid closed.

The invention further contemplates the use of a plurality of these devices in a single car. For instance, it may be desirable to use two, three or even four to a single vehicle and any multiple of these in a car.

The invention further consists in the novel arrangement, combination and construction of parts more fully hereinafter described and shown in the accompanying drawings.

In these drawings:

Fig. 1 is a side elevation showing a plurality of the devices in use.

Fig. 2 is a view along the line 22 of Fig. 1.

FFig. 3 is a view along the line 33 of Fig. 4 is a plan View of the device in the inoperative or folded position.

Fig. 5 is a longitudinal view of Fig. 4.

Referring now to the embodiment illustrated, there is shown at 1 the timbers of a car floor into which has been sunk a casing 2 carrying a rail 3 secured to the bottom thereof. The casing and rail are made fast to the floor by means of U bolts 4 which pass over the rail 3 and extend below the floor proper.

The casing 52 may conveniently consist of a sheet-iron orsteel box or the like, having a cover 5 hinged to one longitudinal edge thereof, so that when the device is in an inoperative position, the lid may be closed and the car floor restored substantially to its initial condition for use other than the accomgodation of vehicles, and such as is shown in Slidably engaging the rail 3 are two feet 6, each of which is provided with downwardly and inwardly projecting portions 7 underlying the projecting head 8 of the rail 3. This construction permits of each foot being slid to any desired position on the rail, yet upward movement is resisted due to the interlocking feature.

Either or both feet 6 may be provided with pivoted locks 9 which are adapted to enter sockets provided at frequent intervals inthe top of rail 3. Thus, by depressing look 9 either or both feet may be definitely pos1- tioned on the rail at the desired location and tubular sleeve 13, containing a cushioning element such as a compression spring 14, bearing against one end of a rod 15 which telescopically engages the sleeve 13. A stud 16 on the rod 15 and riding in a slot 17 in the sleeve, limits the outward movement of the rod and consequently the thrust of the spring. Other cushioning means such as a rubber may be used in place of the spring.

. of the bolt.

To the upper end of the rod 15 there is detachably secured a bracket 18 comprising two complimentary shapes l9 and 20, hinged together so as to swing over and enclose a part of the vehicle to be secured to the car floor, such for instance, as the axle as shown in Fig. 1. A pivoted bolt 21 is carried by one of the complimentary parts 19, the shank of the bolt being adapted to lie in the bifurcated end of the other part 20. Thus, when the -members are in the position shown in Fig. 1

the bracket may be secured in place by means The complimentary part 20 is provided with an eye 22 for a purpose described hereinafter.

The other leg may conveniently comprise a lower portion 23 pivoted to its foot 6, and having a finger 12 to insure engagement of the lock 9 with its socket. The leg is further V provided with an upper portion 24, connected as by a turn buckle 25 to the lower portion so that the over all length of the leg may be adjusted at will. The upper end of the member 24 is hook-shaped as at 26 to engage the eye 22.

As thus shown, it will be seen that by suitably separating the feet on the rail and locking the same in that position, the two legs,

one rigid and the other resilient, may be arranged to grasp the axle of a vehicle positioned thereover. The automobile or other vehicle maythen be drawn tightly against the floor by manipulation of the turn buckle on the rigid leg.

Where desirable a similar operation may be performed with a duplicate device on the front axle, and the invention contemplates the provision of a plurality of brackets for attachment to the spring or axle conforming to the shape of that part. For instance,

in Fig. 1 the bracket grasping the front axle is shown at 27 to be substantially rectangular in its complete configuration.

In order to take up any slack in the resil- .ient leg after the vehicle has been placed in position, the brackets 19 and 27 are secured to a threaded rod section as at 28, threaded into the end of rod 15. Thus, by suit-ably rotating therod section 28 and bracket, the over all length of the resilient leg may be adjusted to either take up slack or to even put the cushioning element 14 under initial tension as desired. A set screw 29 may be used to lock the rods 15 and 28in the desired relation.

By reversing the location of the legs at the front and rear of the car it will be seen that the compression spring in the resilient legs permits a certain fore and aft movement, although this movement is definitely limited by the rigid legs.

Theturn buckle leg servesithe purpose of taking up any upward thrust, yet being pivoted, allows the vehicle a restricted float,- ing action fore and aft on its pneumatic tires. The shock-absorbing leg effectively cushions this fore and aft movement and takes up end thrust, so that the single device allows the vehicle a certain amount of flexible movement yet this movement iscushioned in all directions.

It is contemplated that it may be necessary or desirable to use four of these devices to a single vehicle, valthough it may be .found that three or even two w ll suffice.

It is customary to ship a plurality of automobiles in a single car and, therefore, there may be a number of groups of these assem-- blies arranged on the car floor so as to accommodate as many automobiles as there is room for them in the car.

In folding the device it will only be found necessary to remove the locking member 9 from its recess or socket and slide the feet to the end of the rail whereupon the legs may be folded down upon the top of the rail and the cover closed.
