SPECIFICATION forming part of Letters Patent No. 660,891 dated October 30, 1900` I Application filed May 29, 1900. Serial No. 18,4044.l (No model.)

T0 all whom, t may concern,.-

Be it known that I, JAMES COWAN, a subject of the Queen of Great Britain, and a resident of Aiea, Oahu, Hawaii, have invented a new and Improved Stake-Holder, of which the following is a full, clear, and exact description.

This invention relates to improvements in stake-holders, particularly stakes for railwaycar platforms; and the object is to provide a holder from which a stake may be quickly and easily removed, and, further, to provide a stake-holder having no detachable parts liable to be lost.

vI will describe' a stake-holder embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a portion .of a car-platform, showing a stake-holder embodying my invention as applied thereto. Fig. 2 is a sectional elevation on the line 9c of Fig. 3. Fig. 8 is a front elevation. Fig. 4 is a side elevation. Fig. 5 is an end View of an operating-shaft employed. Fig. 6 is a.

side view thereof. Fig. 7 is a section on the line y y of Fig. 8, showing a modication; and Fig. Sis a section on the linezzof Fig. 7.

The stake-holder comprises a casing having a back wall 1, side walls 2, a stop 3 at the lower end, with which the lower end of a stake may engage, and a swinging front plate 4. The front plate 4 is mounted at its lower end on an eccentric-shaft 5, having bearings in the side walls 2, and this shaft has an outward projection 6, provided with an opening into which an operating-lever 7 may be passed. It is to be understood, however, that this operating-lever is not a fixed portion of the device, as it may be removed andv placed in any convenient holder. At the upper end the front plate 4 has lateral projections 8, de-

signed to pass through outwardly-opening recesses 9, formed in the front edges of the side plates 2 and to engage in recesses 10 at the upper portion of said recesses 9, as plainly indicated in the drawings. A spring l1 is attached to the stop 3 and has its free end engaged against the outer surface of the swinging frontplate 4. This spring l1 is designed to automatically move the front plate to pass the lateral projections 8 into the recesses 9. A spring 12 is connected at one end to a stud 13 on one of the side plates, and this spring is coiled around the projected end 6 of the eccentric-shaft and has its end attached thereto; but the spring maybe at the opposite end- In the operation ot' this example of myimprovement when it is desired to loosen or release a stake, so thatit may be easily removed, the eccentric-shaft is to be rocked by means of the lever 7, and this rocking motion will cause the front plate 4 to move downward, disengaging it from the recesses 10 and then moving it slightly outward through the recesseslgto the 'position indicated in Fig. 4. The pressure thus being relieved from the stake, it is obvious that the stake may be readily drawn out. Upon releasing the lever 7 the spring 12 will rotate the eccentric-shaft, causing the front plate to move upward, so that it will again engage the recesses 10. Before this upward movement the spring 1l will force the front plate against the walls 2, and before any upward movement takes place as the eccentric revolves the front plate 4 will be raised to position and into the recesses 9.

In Figs. 7 and 8 I have shown the front plate 4 as attached to a shaft 14, which has its ends secured to crank-arms 15, extended from a rock-shaft 16, having bearings in the side walls or plates 2 of the device, one end of said shaft being projected and provided with an opening to receive an operating-lever,

as before described. In this example ofthe improvement the shaft 14 is rocked and the front plate 4 moved upward by means of a spring 17, attached to the stop-plate 8 and engaging against the lower end of said front plate, as indicated in Fig. 7. The spring 11 engages with the outer surface of the front plate, as before described. Obviously by rotating the rock-shaft 1.6 the crank-arms 15 will draw the front plate 4 downward, andthe operation thereof willbe the same as before described in connection with the example shown in Figs. 1 to 6, It is to be noted that the crank-arms15 and the eccentric-shaft 5 are equivalents, as they are both cranks in fact.

ICO

l'lavinpr thus described my invention, i claim as new and desire to secure by Letters Patent.-

l. A stake-holder, comprising side plates, a swinging front plate, means for swinging said front plate to open position, and means for automatically moving said front plate to its closed position, substantially as specified.

2. A stake-holder, consisting of side plates and a back plate, a swingingr front plate adapted for locking engagement with the side plates, and means for simultaneously moving said front plate downward and outward, substantially as specified.

A stake-holder, comprising side plates and a back plate, a swinging front. plate adapt ed for locking engagement with the side plates, an eccentric-shaft on which said front plate is mounted, a spring engaging with the front plate, and a spring connecting at one end to a side plate and at the other end to the eccentric-shaft and operating to move the front plate to its closing position, substantially as specified.

4. A stake-holder, comprising`r side plates, an eccentric-shaft having hearings in said side plates, the projectingr end of said shaft beingr provided with au opening to receive an operating-lever, a front plate mounted on said eccentric-shaft, lateral projections at the upper end of said front plate adapted to pass into outwardly-opening recesses in the side plates,'and to engage at the upper ends in recesses formed in the side plates, and means for automatically moving the front plate to its closing position, substantially as specified.

5. A holder for a oar-stake, comprising a casing having,r a swinging front wall or plate, and means for automaticall)T moving said front wall or plate to looking connection with the casing, substantially as specified.

' 6. A stake-holder, one Wall of which is mounted to swing, and means for raising and lowering the said wall, in addition to the swinging movement, the said raising and lowering serving to engage and disengage the Said wall.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
