T0 all whom it may concer/n.'

Be it known that I, AUGUST JAEGER, a citizen of the United States, and a resident of the city of Grand Rapids, in the county of Kent and State of Michigan have invented a new and Improved Draw-loard Fastener, of which the following is a full, clear, and exact description.

This invention relates to improvements in draw board fasteners, anobject of the invention being to provide an improved fastener which is especially adapted for securing a drawboard against movement and which permits the easy removal of the fastener when desired.

Draw boards such as are commonly used in loading and unloading freight cars from or onto piers, docks, platforms, etc., have heretofore been Spikes driven through the board itself, and

sometimes located at the ends of the boards. i

bility of turning while the ends of the webs act as shoulders They not only in manyl cases do not function properly but are di cult to remove, and result in injuring the board, the car and the platforms. With my improved device the board or the platform is not injured and the board is securely held, and the fasteners can be conveniently and quickly removed when desired. v

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.. c

In the accomp n ing drawingsf- Figure l is a ragmentary perspective view illustrating my improvements;

Fig. 2 is a view in vertical section showing a fastener in securing position;

Fig. 3 is a broken lan view; and

Fig. 4 is a perspective view of a fastener in operative position.

l represents a car and 2 a platform. 3 is a draw board over which trucks are adapted to run to load or unload the car from or onto the platform.

The board 3 is held against movement by my improved fasteners 4, any desired'number being employed at each end of the board, although in many cases one 4fastener 'at each end will be all that is necessary.

The fastener 4 comprises arelatively wide head 5 having at each end integral webs 6 extending from the rear edge of the head to a point removed frm the front edge thereheld by ordinary nails or of so that a lip 7 is provided in advancev of the webs 6 to'overlap the draw board 3 with the end of the draw board located against the forward ends of the webs.

The webs are preferably of substantially the same thickness as a draw board so they have a firm bearing against the Hoor and are held against rearward movement by a pair of-

sharp prongs

8, 8, which are integral with the webs 6, 6, and extend downwardly from the same at their forward ends.

The prongs are preferably circular in cross-section and taper to their lower pointed ends so that they can be convemently driven in the iioor and easily removed without damaging the floor.

An ordinary hammer can be used to drive the fastener in place and the claw thereof can be inserted under the head 5 between the webs 6, 6, and easily remove the fastener.

The two prongs 8, 8, prevent any possimovement of the fastener to prevent lonlgitudinal movement of the draw board. he overlapping lip 7 vholds the end of the draw board against upward movement, and hence the jars and jolts of trucks passing onto, over, and off the board will not jar loose the fasteners.

When desired, the fasteners canbequickly removed and little, if any, damage will have been done tothe floors and draw board as the holes will quickly close, owing to the fact that they have been smoothly made by the round taperin prongs.

anges might be made in the general form of the parts described without departing from m invention and hence I do not limit myse f to the precise details set forth, but consider myself at liberty to make such changes and alterations Various slight c as fairly fall within the spirit and scope of` the appended claims.

I clalm:

1. A fastener, comprising a relatively wide head, a pair of integral webs on the under face of thehead spaced apart and from the forward edge of the head, whereby in ros a projecting lip is provided, and pron tegral with the webs and projecting own-f wardrlly from the forward ends of the webs 2. he combination with supports and a draw board, of fasteners at the ends of thef draw board, said fasteners' compri/sing rela-',l'lo

integral webs on the tively wide heads,

and located against` the heads spaced apart `supports and bearing against the ends of the the head at the ends of the head, said webs draw board, tongues on the heads projecting having their forward edges spaced from the over the draw board, and isharp prongs on forward edges of the head, pins projecting 10 the Webs driven into the slipports. from the forward portions of the Webs, and

3. A fastener of the character described, said head, Webs and pins constituting a sincomprising a relatively Wide head having a gle integral metal structure. Hat under face, webs on the under face of AUGUST JAEGER.
