COMBINED RAIL-JOINT AND SECURING DEVICE.

Specification of Letters Patent. Patented Sept. 17, 1912.

7 Application filed l 20, serial No; 692N13- To all whom it may concern:

Be it known that I, CORNELIUS F. Conn- SON, a citizen of the United States, residing at Memphis, in the county of Shelby and Stateot' Tennessee, have invented certain in Combined RaiLJoints and Securing Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as'will enable others skilled in the art to which it appertains to make and use the same. a

'My invention relates to an improvement i in combined rail joint and securing devices,

embodying my invention.

and itconsists in the details of construction as will bemo're fully described and pointed out in the claims.

In the accompanying drawings, Figure 19 is a view in perspective of a railroad joint- Fig. 2 is a view in plan of the same. Fig. 3 is an end elevation in section through the rail. Fig. 4: is a view in perspective of the chair. Fig. 5

' is a view inperspective of one of the combined coupling jaws and fish plates and Fig. 6 is an end elevation of a clamping jaw adapted particularly for use at curves.

' sides,

1 represents the wood ties, and 2 a chair extending from one tie to the other, and secured to both. One chair is employed for each joint in the track and each chair is provided in its topsurface at its opposite and near each v end, with recesses 3, and is also provided with two dovetailed recesses 4, one adjacent each side of the chair, and extending throughout the lengt of the latter. .The portion 5 of the chair intermediate the dovetailed recesses 4:, forms the seat or support on which the adjacent ends of two rails rest, and which forms a support tor the latter between and on the two ties 1 which carry'the chair. The seat 5 of the chair is of slightly less width than the base flanges 6 of the two rails 7 so that the latter overhang the dovetailed recesses- 4 at both sides of the rails.

The chair isprovided within the recesses 3, with spike holes 8, through which spikes 9 are driven to secure the chair to the two adjacent ties, the recesses 3 forming housings for the heads of spikes 9, which, when the parts are assembled, are covered and concealed by the rail clamping block 10. Each clamping block 10 is approximately as long as the chair, and each is provided with a dovetailed tenon 11 projecting from its lower iace,avh1ch is of a size and shape to make a close fit with one of the dovetailed accesses or mortises in the chair 2, and the two clamping blocks for each chair, rest on the upper face of the latter and cover and conceal the spikes 9. Each clamping block l0 is provided with a jaw 12 conforming in shape to, and resting on the upper surface of the base flanges 6 of the, abutting rails, and each is also provided with a groove 13 to receive the edges of said basefianges, so that when the rails are in place, the clamping blocks 10 will engageboth the upper and lower faces of the base flanges and positively prevent any independent latcral movementof either rail and assist in preventing any vertical movement of the end of either rail.

The grooves 13 are immediately over the inner edges of the dovetailed tenons 11; so that the base flanges, of the two rails rest on and overthe joint between their seat 5, and the dovetailed tenons 11, and operate by" their weight to hold these parts down block are continued upwardly alongside the webs=of the rails, sufficiently high, and preferably up under and in contact with the heads of the rails, to form fish plates 12 the latter being provided with holes for the passage of the bolts which secure the fish plates together, and to the rails.

in proper'position. The jaws 12 of each The rails are secured to the ties by spikes 14 passing through holes formed in the chair adjacent to one'end of each mortise, and the two clamping plates are recessed, each atone end, as at 15, to receive and cover the heads of the spikes l4; and lock them against partial or complete withdrawal.

The dovetail mortises t and tenons 11, are slightly oblique with relation to the axes of the rails, so that in assembling, the clamping blocks will move slightly toward the rail, or toward the other and bind against the upper faces of the base flanges of the ralls with a wedging action.

The spikes 14 securing the rails to the tie, are located one at each end of the chair or opposite sides of the rails, so as to permit the tenons 11 on the clamping blocks to be driven into place from the opposite ends, and when in place the heads of the spikes are within the recesses 15, in the blocks, and arecovcrcd and concealed from above by long 1 driven into the ties,
