Application filed May 5, 1911.

Patented Aug. 8, 1911.

Serial No. 625,403.

To all whom a may concern:

Be it known that I, ANDREW MGNAUGII- won a citizen of the United States, residing at \lfilliamsport, in the county of Lycoming and State of Pennsylvania, have mvented certain new and useful Im )rovements in Chocks, of which the following is a specification.

My invention relates to improvements in checks and has particular reference to a check adapted for use in packing freight to prevent the slipping thereof.

The leading object of my invention is the provision of a chock adapted for use in packing boxes, barrels or other heterogeneous forms of freight into metal or other cars,

vessels or vehicles to prevent the slipping thereof.

A further object of the invention is the provision of a device of this character which will dispense with the use of props in cars or vessels on land or water or will serve to supplement the same and which will serve to secure the freight and prevent the slipping thereof when it is packed in metal or other cars or vessels where it is impossible to nail down cleats or like devices to assist in securing the contents of the cars, vessels or vehicles.

To attain the desired objects of my invention, I have provided a platform or plate upon which the freight isto be packed, said plates having teeth orbarbs struck there-- from, certain of the barbs being adapted to grip the floor of the car while the others extend upward and catch hold of the freight, the invention further residing. in the novel features of construction and combination and arrangement of parts for service substantially as described andas illustrated in the accrmipanying drawings.

Figure 1 represents a perspective view of the device in use. Fig. 2 represents a perspectiveview of the chock, and Fig. 3 repre sents a perspective view of a modified form of my chock.

. In the drawings, the numeral 1 designates the floor of a freightcar, while resting upon the" said floor are the prongs or barbs 2 of the plate 3, said plate 3 having resting thereon the box 4 having its under side engaged by the upwardly extending lip or lug 5, likewise struck from the plate 3.

In Fig. 3 I have shown a slightly modified form of my invention, which is of rectangular shape, and comprises a plate 6, having,

dependlng barbs 7 at the corners, also the series of barbs 8, and the lip or lug 9.

From the foregoing description taken in connection with the drawings the construction and use of my improved device 'will be readily understood and its advantages be fully up arent and it will be seen that I have provide a strong, sim 1e and durable device which can be employe an unlimited number of times, which can be quickly .and easily placed in position and will not damage either the freight or the car, which will not jolt loose as props and like fastenings do, and which isadapted for use with various articles, light or heavy, and which may be readily removed without the use of tools. It will also be observed that I have formed in my plates the opening 10 by the stamping up of the lip or lug 5, said opening serving to receive a nail or hook to suspend the device when not in use.

The hereinv described chock will obviate (in whole or in part) the necessity of using nails, spikes, cleats or other projections in the floor. or sides of cars, constructed either of wood or metal, or a combination of both, in the holds and on decks of vessels, floating docks, and wharves, or any vehicle carrying- In testimony whereof I affix my signature in presence of two witnesses.

ANDREW MCNAUGHTON. Witnesses: J. C. HILL, WM. C. KING.
