is experienced in keeping the rails seated on mounted the base of the rail in a chair hav- Be it known that I, BEVERLY J. Gnmrns, of South Framingham, county of Middlesex, State ofMassachusetts, have invented an Innprovement in Chairs to Hold Railway-Rails, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

In laying tracks for railways great d ifliculty and the loosened spikes are liable to be re moved and the sleeper is worn. To obviate the tendency of the rails to spread, I have ing walls or projections to contact with the opposite edges of. the base, and this chair is providcd'with a pocket, in which may be placed a locking device to engage a suitable notch or projection of the spike when the same is'driven through said chair, so that its l a chair has ever been provided with a shoulhead overlaps said flange. i

Figure 1, in perspective, shows two rails abutted in one ofmy improved chairs and a.

fish-plate applied to the rails, a portion of the chair being broken out to showthe locking device; and Fig. 2 shows a rail in-achair, oneof the pockets being broken out.

Let A A represent rails of usual construction, each having a flanged base a. The fishplates B may be applied to the junction of two rails by suitable bolts 1) in usual manner.

My invention relates more especially to the chair 0. It is composed of a metallic plate havingsuitable shoulders c to constitute ab utmen'ts to restrain any sidewise movement of a the rail under pressure of a car running onable stud e c, said spring being contained in said pocket and kept therein by a pin or stud e".

In Fig. 2 the device e is made as a'single spring held in place in the pocket by a suit- When a spike is :being driven through the chair into the sleeperor tie, the

.wedge part2 of the projection 01 acts against the end of the locking device and forces said end back, and when the spike has been 'fully driven the spring part of the locking device acts to cause the freeend of I the locking device to enter the space (1 and hold the spike locked in its driven position. To withdraw a spike, a wedge maybe driven into the. open end of the pocket and, acting against one side of the locking device near its end, said looking device may be forced back to free the spike and let it be lifted by any usual driver or tool.

When a fish-plate is needed, it may be pro: vided near its lower end with a downturncd lip a, which may be interposed between the edge'of the base of the rail and the shoulder a.

I am not aware prior to my invention that der or shoulders to contact with the 'base of the flange andoutside said shoulder or shoulders with a pocket to receive a locking device, a spike being extended through said pocket and chair, and hence this invention -Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-' 1. A rail-supporting chair adapted to rest on and cross a tie transversely, said chair presenting parallel projections to receive between them the edges of the base of the rail, and a longitudinal pocket at the edge of the rail, said pocket having a transverse spikehole and receiving a locking device to cooperate with and lock in position aspike driven through said pocket of said chair into a tie, substantially as described.

2'. A chair composed of a bottom plate, having a pocket at each longitudinal edge, said pocket being provided .with a transverse spike-hole, a movable locking device ins-aid pocket and crossing said spike-hole and adapted toenter a notch in one edge of the spike, substantially as described.

3. A chair having a pocket provided with a transverse spike-hole, a locking device pivoted in said pocket and crossing said spike hole, and a spike having a' notch at one edge to be engaged by said locking device, substantially as described.

4. A chair having a pocket provided with a transverse spike-hole, a locking device in said pocket and crossing said spike-hole, a spike having a camshaped projection and a notch, said projection acting against said locking device to spring it back so that it may thereafter return and enter said notch, substantially as described.

5. A chair to support meeting ends of rails, said chair having a shoulder, a fish-plate bolted to saidrails and havinga lip extended into the space between the shoulder of the chair and'the edge of the base of the rail, and a spike driven through said chair and overlapping the fish-plate, substantially. as

described.

6. A chair for railway-rails, it presenting parallel shoulders to hold the edges of the base parts of therails in position against lateral displacement, pockets extended parallel with said shoulders and having spikeholes, suitable locking devices located in said pockets, and fish-plates united to the ends of rails and'extended toward said spike-holes,

combined with spikes driven into said spike- 1 holesand overlapping parts of said fishplates, substantially as described.

In testimony whereof I have signed my name to this specification in the presence'of
