. .RAIL-CHAIR.

Specification of Letters Patent.

Application filed November 26', 19.12. Seria1 N o. 733,615.

To all whom, t 'may concern.'

Be it knowrfthatl, JAMES R., SMITH, a subject ot the King of Great Britain, residing at Kildonan, lVinnpeg, Manitoba, Canada, have. invented certain new and useful Improvements in RailfGhairs, of which the following is a specification.

This inventionI relates torail chairs.

'My object is to provide an improved rail chair having but two. parts constructed and arranged so that they will ossess great strength and. durability and will so.- bear on thel web of the rail that itis strongly braced, it bein a well known fact that the weakest part ot a rail is its web. v

Another obiect of the invention is to provide a rail: chair O-.improved construction having anintegral base plate and web brace and a movable web brace, together with, im-

90; proved means for ,slid'ably attaching; the

'moa/able web'brace to the chair in such manneig vthat the movable web brace may bev readily-shifted to. permit the rail to be;

Seated in thechair and then adjustedv and 25. held to the chair and against the web of the rail, by spikes driven into the ordinarytie and also constructed and adapted. to the chairso that the said movable rail brace may be readily detached.A from. the chair after thejrailhas been removed. f'

The. invent-ion consists, first, in a rail chair having a base and an integralweb brace, avdetachable web brace,l and a novel interlocking connection between the web brace. and the chair brace; second, in a rail chair having an'integral base and brace and provided with locking flanges, vand va detachable brace having lugs or lips 'adapted to interlock with said lianges when-the movable brace is imposition andl to be secured by spikes used forV connecting the chair to the tie, but which can be slid in one directiony to permit the lacing of the rail on the chair and then ma e to lock the rail in position and which is also so constructed and adapted to the parts of the chair that said' detachable brace may, when the rail is: notin position,

be interlocked with the' chair or removed therefrom.

In the accompanying drawings: Figure 1` is a perspective of the chair vandl a section.-

of a rail held thereby, dotted lines re resent# ingthe manner in which the movab e brace may be slid back before s iking to ermit the placing of the rail 1n -t e chair; 1g. 2.

ing how the movable'bracemay be detached r from o r interloclred wit the chair; and Fig.,` 5., an enlargedperspectifve'of one of the -langes ont-he base v of the chair.

The base 1 and one` of the braces' 2 are formed integral, the said brace 2 bei posh tioned, whenthel chair rs1-n pla-'ce on t e tie,

eitherI inside or outside of the raill'according' v to; the requirements of the; section o-ii track on which the chair is used- `The brace or abutment, 2 is preferably heavier than the,

- detachable brace, as itis intended to be so located that it willi take up' the greatest strain exerted by the rail" on the chair, the

detachableI brace not requiring so. much4 strength.

v The conformation 3. of. the face of the brace-.2 corresponds-to the contour of the upper facey ozfl thc'base and tlleweb. of the 1in; over-hanging relation to the base but ternnnat-ing at a shoulder 8. The inner ends 9 of' the lianges are positioned and formed so that when the rail 4 is tilted into or out of position under the brace 2, its opposite base will just` clear the said ang'es. Conse- :quently, the flanges strengthen the base 1 as they extend comparative-ly closeto the base of the rall at their inner ends 9, and being thick at their -overhanging portions 7, they are not appreciably weakenedby the underr i out or over-hanging construction employed.

Thedetachahle brace is shown at l() and it I is provided with an abutment face 11 adapted to bear against the web of the rail 4 and has a conformation at 12 adapting it to the top and edge of the `base of the rail when it is intheA position shownin Fig. 1. The detachable brace 10- is adapted to snugly, yet easily, fit between the

overhanging flanges

6 and 7 and it is provided with laterally ex tending lugs 13 and '14 which take under the ,overhanging flanges 6` and 7, as shown in IFig. 2.. The

lugs

13 and 14; are relatively `short so that they are adapted 4for travel in the channels 15 below the overhanging

flanges

6 and 7 and hence they permit the detachable brace l0 to be moved 1n both directions. W'hen moved toward the brace 2, the

lugs

13 and 14 clear the ends 7a of the flanges shoulders 8, at which time the abutment face A 11 has passed back so that it is substantially inline with the surfaces 9. Consequently, the rail 4 can'be tilted in underneath the brace 2 and seated on the base land the .brace 10 can then be slid forward to the posit-ion shown in Fig.,1. The brace 2 is provided 'with spike holes 16 to accommodate round shank spikes having round heads 17 which seat in depressions 18. The spikes are to be, driven into the wooden tie in the usual manner. The base 1 has round 0 enings 19 and the brace 10 has correspon ing holes 20 which, when the parts are in the position shown in Fig.'1, register with holes 19. The brace 10 has concavities 21. Round shank kspikes 22 may be passed through the

holes

19 and 20 when the rail is seated in the chair and said spikes driven into the ordinary tie, the round heads 23 of the spikes seating in the concavities 21. The spikes 22, therefore, not only s ike the chair tothe tie, but they secure the race 10 to the chair in such position that the lugs 13 are in the channels 15 and the abutment faces 5 and 11 bear firmly against opposite sides of the web of rail 4.

Assuming that the chair has been spiked f and it is desired to release the rail, the

spikes 22 are withdrawn, whereupon the brace 10 may be slid back, as shown in dotted lines in Fig. 1, and the rail can then be tilted out of the chair.

Having thus described my invention, what I claim its new and desire to secure by Let-` ters Patent, is

1. In a rail chair, the combination of a chair base having overhanging anges and shoulders underneath said flanges, a slidable and detachable brace adapted to fit between said iianges and to rest on the chair base below and provided with lugs slidable underneath the anges and adapted for separation from said flanges when moved in one direction and to abut the shoulders when moved in theopposite direction.

2. In a rail chair, the combination of a chair base having overhanging ianges and shoulders underneath said ianges, a slidable and detachable brace adapted to lit between said flanges and to rest on the chair base be low and provided with lugs slidable underneath the anges and adapted for separation from said anges when moved in one direction and to abut the shoulders when moved in the opposite direction, and a brace formed integral with the base aforesaid, said fixed and movable braces rhaving a conformity adapting them to the base and the web of the rail and arranged to hold the rail bel tween them.

3. In a rail chair, the combination with a chair base and a rail brace'connected thereto, said base being provided With flanges having over-hanging parts providing chan- -nels between themselves and the chan' base,

said channels terminating in a shoulder at their outer ends' and being open at their inner ends, of a slidable and detachable rail brace received between the anges and provided with lugs adapted for rece tion in the channels and so related thereto t at the slidable 'rail brace may be slid outwardly without detachment from the iianges to permit the rail to be placed in position or removed from the chair, said lugs also permitting the rail brace to be slid inwardly when the rail is out of the chair to permit the lugs to become detached from the overhanging flanges and to enable the brace to be removed.

4. In a rail chair, the combination with a chair base and a brace connected thereto,

of a slidable rail brace resting on the chair,

connection with the u per part of the base.

5. In a rail chair, t 1e combination with a chair base and a brace resting on the chair base and connected thereto, of a slidable rail brace having a detachable interlockin connection with the base, the base and t e superposed slidable brace having openings adapted to receive spikesor fasteners when brought into register with each other and being adapted to register when the brace 1s in position to secure the rail in the chair.

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