' This invention relates to means for securing automobiles in freight cars during shipment. I

The main objects of this invention are to provide an adjustable anchoring means for wheel blocks and the like to provide an anchoring means which can be stored or housed in the freight car floor flush with the top surface thereof; to provide an anchoring means which is adapted to be permanent equipment not ordinarily removable from the freight car; to provide an improved anchoring means for wheel blocks which will permit the blocks to be adjusted both laterally and transversely of the freight car floor, as well as permit their positioning in an alignment which is at an angle to the longitudinal axis of the car floor, whereby an automobile may be anchored at an angle to the next adjacent one so as to nest or inter fit the front ends of two automobiles; and to provide an improved anchoring means which is readily shiftable to various positions in the freight car and which may be quickly and easily secured in the desired position.

An illustrative embodiment of this invention is shown in the accompanying drawings,

Fig. 14.- is a fragmentary view in side elevaings a freight car 20 has the floor 21 thereof channeled out to provide s aced

paral el grooves

22, 23, 24 and 25.

tr1ps of strap iron 26 and 27 are secured by bolts 28 and 29 to the car floor with the marginal edge of the straps extending over the sides of the grooves and with adjacent edges of the iron straps in "spaced relation so as to form a series of undercut grooves in the car floor.

The undercut grooves are provided with a plurahty of joint members, each of which comprises a pair of rectangular

shaped slide members

30 and 31 which are adapted to slidably fit in the undercut grooves between the under sides of the overlapping iron strips and the floor of the grooves. The

slide members

30 and 31 are pivotally mounted on the oppositely extending

trunnions

32 and 33 of Fig. 7 is a sectional view taken on the line a cross-head member 34. The cross-head 34 is transversely bored to receive the cylindrical end of a square post member 35, which end is rotatably mounted in the cross-head and retained therein by having the end of its tip portion riveted. The body portion of the post member 35 is provided with a transversely extending tapered slot 36 which is adapted to receive a split key 37 therein.

The post member 35 is adapted toextend through and fit within a rectangular shaped slot 38 formed in the channel-shaped end 39 of an anchoring bar 40. The slot 38 is preferably formed by cutting away a portion of the web of the channel-shaped end 39 and the flanges thereon are adapted to snugly embrace opposite sides of the post 35.

Means are provided for retaining the anchoring bar 40 on the post 35 and at the same time permit relative movement therebetween, and comprise a transversely extending pin 41 mounted in the extreme end of the post 35 adjacent one corner thereof with the ends protruding from opposite sides of the post so as to engage the flanges of the channelshaped end 39 of the anchoring bar.

The flanges of the channel-shaped end of the anchoring bar, at a point within the limits of the slot 38, are provided with a pair of transversely registering notches 42 which are adapted to receive the protruding ends of the pin 41, thus permitting the anchoring bar and post 35 to be folded so as to bring the an choring bar in prolongation of the post. The proportions of the joint members and the anchoring bar are such that the bar 40, when folded in prolongation of the post 35, will pass between the adjacent edges of the strap members 26 and 27 and fit within the channel or groove in the car floor flush with the surface thereof.

' The end of the anchoring bar 40 opposite to the end 39 is provided with a transverse opening 43 therethrough which is adapted to receive a post member 35 of another joint as .islembly in the next adjacent groove of the car oor.

lrVheel blocks 44, preferably of wood, are provided with transverse slots 45 in the base thereof for fitting snugly over the anchoring bars 40. A key-Way 46 is provided at one side of the slot 45 for receiving a suitable key to wedge the wheel block 44 in any desired position along the anchor bar 40. The 0pposite sides of the bar 40 are grooved out slightly as shown at 47 and 48, in registry with the ke -way 46 so as to be more securely held by the ey.

In the operation and use of this invention the freight car fioor used for shipment of automobiles are routed out to provide two pairs of channels adjacent the opposite sides of the car. The metal straps 26 and 27, preferably countersunk so as to be flush with the car 'floor, are bolted to the floor so that their marginal edges overlap the channels routed out in the car floor, thereby providing a series of undercut grooves. Each of the undercut grooves '22, 23, 24 and '25 is provided with a plurality of the joint assemblies which comprise the

slide members

30 and 31, connecting cross-head 34 pivoted therebetween, and post member 35, which is rotatably mounted on the cross-head.

Each of the joint assemblies in one groove of each pair, shown in the drawings as the

grooves

23 and 25, has anchoring bars 40 mounted on the post members 35 and retained thereon by their respective pins 41. The slots 38, through which the post members 35 pass, and the notches 42 in the flanges of the channel-shaped ends of the anchoring bars permit the anchoring bars to be swung out into prolongation of the post 35, the ends of the pins 41 passing down into thenotches 42 when in this position and the post member 35 fitting up between the side flanges of the channelshaped end 39.

\Vhen in this position the anchoring bars 40 may be folded down into the slot in the car floor by rotation of the cross-head 34 on its

trunnions

32 and 33. The post members of the joint assembles in the

slots

22 and 24 are merely folded down into their respective slots by rotating the cross-heads 34 on their trunnions.

\Vhen it is desired to bring the anchoring bars into use they are raised from their slots and folded so as to be transverse of the post 35, in which position they maybe swung around by rotation of the post35 on its pivotal mounting so as to extend over and overlap the adjacent slot of that particular pair. When in this position a post member of the adjacent slot is raised to a vertical position and the end of the anchoring bar having the aperture 43 passed down over the post.

Wheel blocks 44 are then placed on the anchoring bars with the slots 45 in the base of the block fitting over and snugly embracing the bar 40. A pair of anchoring bars with wheel blocks facing toward each other are used for each wheel of the automobile to be anchored. When the automobile is in correct position in the freight car the wheel blocks, anchoring bar therefor, and joint assemblies on the opposite ends of the anchoring bar, are moved up until the wheel blocks snugly engage opposite sides of the automobile wheel as shown in Figs. 6 and 7 of the drawings.-

VVhen in this position the split web-shaped keys 37 are passed through the tapered slots 36 in the various posts 35 and driven therein so as to wedge the joint assemblies tightly in their respective grooves, thereby preventing sliding of the joint assemblies in their grooves. The ends of the split keys 37 are then turned outwardly so as to retain the joint assembly in tightly wedged position. The wheel blocks 44 may then be secured to the anchoring bars 40 by driving key wedges in the slots 46 which are provided in the wheel blocks.

When it is desired to place one of the automobiles in the car at an angle to the longitudinal axis thereof with the front end nested or inter-fitting with the front end of another the anchoring bars may be turned so as to be perpendicular to the plane of the wheels due to the slot 38. The slot in the end of the bar permits lengthwise movement thereof within certain limits and thus permits a wide range of adjustment.
