CHAIR FOR RAIL-JOINTS.

SPECIFICATION forming partof Letters Patent No. 747,647, dated December 22, 1903. Application filed April 3, 1903. Serial No. 150,997. (No model.)

To all whont it may concern:

Be it known that I, LEO L. SAVOIE, a citizen of the United States, residing at Amite, in the parish of Tangipahoa and State of Louisiana, have invented certain new anduseful Improvements in Chairs for Rail-Joints; and I do declare the following to be a full,

such as will enable others skilled in the art to which it appertains to make and use the .same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a newandimprovedchairforrail-joints,and the preferred construction of the same is shown in the accompanying drawings, in which- Figure l is a view in perspective, the two parts comprising the chair being shown slightly separated and the locking-block being shown in dotted lines. Fig. 2 is a plan view of the chair closed. Fig. 3 is an end View of the same. Fig. 4 is a side elevation, and Fig. 5 is a perspective, of the lockingblock.

The chair proper comprises the two basesections A and B, each section comprising an appropriately-formed shoulder to embrace the side of the web of the rail and having an undercut portion to receive the railfoot. The shoulder 1 of the section A is attached to a base-plate 2, on which the foot of the rail rests. Such base-plate has secured on its under surface the two guide- plates 3 and 3. The shoulder 4, of the section B has secured to its under surface the broad guide-plate 5, which slides between the guide- plates 3 and 3, and the under side of the shoulder is recessed to receive and rest upon the projecting end ofthe base-plate 2. The shoulder 1 of the section A is provided with angular sockets to receive the angular heads of bolts 6, which project from the face of the shoulder, and the upper surface of the shoulder lis recessed to form an upstanding ridge 7, such ridge being perforated to receive the bolts 6, and the bolts 6 are threaded for nuts to fit thereon. A locking-block Sis provided to fit in the recess formed in the upper portion of the shoulder 4, and such locking-block has angular-shaped recesses 9 to receive and engage with the nuts on the ends of the bolts -6.

The shoulder 1 is arranged to engage on the inner side of the rail, while the shoulder 4 engages the outer side of the rail, and the enflange should be wider than the vertical thickness of the rail-tread.

The upper and outer ends of the shoulders are beveled off'to remove unnecessary metal, and both sections are vertically perforated to provide passages for spikes or bolts by which the chair is secured to the ties or other supporting-foundation. When in position, the bolts which pass through the shoulder 1 pass also through the broad guide-plate 5, and the vertical b'olts passing through the shoulder 4 also enter orifices in the base-plate 2 and guide- plates 3 and 3 of the shoulder 1. The locking-block is secured to the shoulder l by bolts, which may also pass through the baseplate 2 and guide- plates 3 and 3 and enter the supporting-foundation.

In assembling the parts the section A is placed in position. and the meeting ends of the two rails are placed with the foot of each rail on the base-plate and the web of each rail against the face of the shoulder, the bolts 6 passing through properly-placed holes out in the webs of the rails. The section Bis then placed,the guide-plate 5 sliding between the guide- plates 3 and 3 and beneath the baseplate 2 and the shoulder 4 engaging the outer side of the web of the rail and securing the outer side of the foot between the undercut side of the shoulder and the base-plate 2,while the bolts 6 pass through holes in the upstanding ridge 7. Nuts are then screwed on the ends of the bolts 6, and the locking block is placed in position to hold and lock such nuts from loosening. Lastly, the holdingspikes are driven home, holding the ends of the rails,

the locking-block, and the two sections together and to the supporting-foundation as a unitary structure.

Having thus described my invention, I claim- 1. A rail-joint chair comprising two sections, one section comprising a base-plate and an overhanging shoulder, such shoulder having angularly-recessed seats to receive the angular heads of bolts, the other section com prising a shoulder having an upstanding ridge, and a locking block arranged to fit against said ridge and having recesses to receive and lock the nuts on the ends of the angular-headed bolts,the locking-block and corresponding shoulder being vertically perforated to receive holding-spikes, substantially as described.

2. A rail-joint chair comprising two sections,one section comprisinga base-plate havingguide-plates on its under side,and a shoulder on the upper side of such base-plate, such shoulder being undercut to receive the railfoot and having angular sockets to receive the an gular heads of fastening-bolts,the other section comprising a guide-plate to fit under the base-plate and between the guide-plates thereon, a shoulder attached to said guideplate and recessed to receive the edge of the base-plate and overlie the foot of the rail on such base-plate, such shoulder having an upstanding ridge perforated to' receive the fastening-bolts, and a locking-block arranged to fit on the upper side of the shoulder and having angular recesses to receive and lock the nuts on the ends of the fastening-bolts, the locking block, shoulders, base and guide plates being vertically perforated to receive holding spikes or bolts which hold the several parts together as a unitary structure and secure the same to the supporting-base.

3. A rail-joint chair comprising two sections, one section comprising a base-plate, guide-plates secured to the under side of the base-plate, and a shoulder secured to the upper side of such base-plate, such shoulder being undercut to overlie the rail-foot and provided with angular sockets to receive the angular heads of fastening-bolts, the other section comprising a guide-plate arranged to fit under the base-plate of the first section and between the guide-plates on the under side of such base-plate, and a shoulder secured to the upper side of such guide-plate, the under side of such shoulder being recessed to receive the projecting edge of the base-plate and to overlie the foot of the rail as it rests on such base-plate, such shoulder having an upstanding ridge perforated to receive the ends of the fastening-bolts, and a lockingblock having angular recesses to receive and lock the nuts on the ends of the fasteningbolts, the locking-block, shoulders, base and guide plates being perforated to receive fastening-bolts which pass through such parts and hold the several sections as a unitary structure.

In testimony whereof I affix my signature in presence of two witnesses.

LEO L. SAVOIE.
