Patented July 12, 1932 UNITED STATES' jPn'rlszN'r oFFlcE LOUIS A. CHUBGAY AN D HARRY S. MCCLELLAN, OF DETROIT, MICHIGAN, ASSIGNORS TO CHRYSLER COBPOBATIOILDF DETROIT, MICHIGAN, A CORPORATION 0F DELAWARE SHIIPING DEVICE application med Aprn ai,

This invention relates to a means for securing export articles to railroad cars and more particularly to a means adapted` for adjustably securing export boxes to flat cars with band iron strapping.

In shipping several articles such as'boxes, one on top of the other, it is necessary to hold them down by an adjustable tie so that as the tie becomes loose it ma be tightened down during its course of s `pment. This is usually done by inspectors along the route of shipment. j I

Flexible metal stra s lhave been found most satisfactory to` tie the articles sto be shipped down. The stra s are less'expensive than other known devices and are desirable because they permit the articles to have a certain amount of movement to dampen out the sudden shocks or forces received durin shipment.

eretofore the use of `flexible metal straps has been restricted because no adjustment has been provided. It is therefore an important object of this invention 'to provide an adjustable connection between the car and the strap. e

Another object of the invention is to support the adjustable connection in the stake socket of the freight car.

.Other objects and advantages will more fully appear from the following description taken 1n connection with the accompanyinfr drawing, in which:

i 1 is a side elevation of a railroad car showing an application of my improved device.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is an enlarged detail view of a car stake socket with an adjustable connection therein.

Fig. 4 is a view at right angles to Fig. 3.

Fig. 5 is a ,view corresponding to Fig. 3, showing a modication of the adjustable connection.

Referring to the drawing, we have shown a railroadviiat car 10having a plurality of stake sockets 12 secured to the opposite sides of the car. A plurality of boxes 14 have been placed on the car. The boxes shown are of the type commonly used in shipping dis- 1928. Serial No. 271,709.

As a `means for adjustably securing the opposite ends of the bands to the sockets, we have provided, in the preferred form of our device, a U bolt 2O and a metal plate member 22 having openings 24 through which the threaded ends of the U bolt extend. Nuts 26 on the threaded ends hold the plate in position on the U bolt and the parts form a unit lwhich may be inserted through the lower end of the stake sockets 12. The plate 22 engages the lower surface of the stake socket and the upper portions of the U bolt extends beyond the upper surface of the stake socket to receive the end of the band 18.

The end of the band on the one side is looped through the opening of the U bolt, bent back upon itself, sealed by crimping a metallic member 28 over the edges of the band, where the ends overlap, and forming indented portions, as indicated at 30,` in the edges of the 'member 28 and the edges of two thicknesses of the band. The other end `of the band, at .the opposite side of the car, is assed through the open end of the U bolt and fastened thereto as above described drawing the band tightly down on the boxes and drawing the plates 22 against the lower surface of the stake sockets.

It will be understood that when the boxes are voriginally secured to the car, no adjustments are necessary. The U bolts with the plates 22 are inserted into the stake sockets and the bands applied with'as much speed or ease as though the bands were applied to the stake sockets themselves. After the load becomes loose through jarring in shipment, the nuts 26 may be tightened up by an inspector to further tighten the bands over the boxes.

As a modlication of our adjustable holding means, we have shown as in Fig. 5, a single threaded member 32 having an eye 34 at its upper end to receive the band 18.

It will be understood that various changes including the size and arrangement of parts may be made without de arting from the spirit of ourinvention an it is not our intention to limit its scope other than by the j terms of lthe appended claims.

What we clalm is:

1. The combination with a freight car" havin a pair of stake sockets, one on each side t ereof, a pair of adjustable anchorin members, one extending through each of sai sockets and each having an opening at one end, means on said members abutting the lower side of said sockets `for securing said members against upward movement, Aand a flexible band for securing articles on said freight car having its respectively o posite end portions extending through sai openings and reversely bent under an initial ten- 4 sion upon the adjacent portions of said band, and means securing the endl portion of said band and the vgether.

v 2. The combination with a freight car havin a pair of stake sockets, one on each side t ereof, av air of anchoring members, one extending through each of said sockets, one of said members having an opening at one end, a flexible ba'nd for securing articles on said freight car having one extremity secured to the other member and its opposite end portion extending through said opening and reverse bent upon the adjacent portion of said band under an initial -tension suicient to hold said articles in place during the first stages of their transit, means tensioning sa securing said reverse bent portion to said ad jacent portion, and adjustable means on said anchoring members for conveniently reid band during transit.
