RAIL CHAIR I Filed Aug. 7, 1931 Patented June 12, 1934 .RAIL CHAIR Robert Hill, oakville, Ontario, Canada Application August 7, 1931, Serial No. 555,773 In'Carrada July 7, 1931 14 Claims.

This invention relates to rail chairs generally andmore particularlyto a device of this description inwhich the use of clamping bolts for the rail are dispensed. with.

The objects of the invention are to provide a durably constructed device of this character with aminimum number of partswhich can be most economically manufactured and which will more efficiently perform the functions required of it.

Another object is to provide a rail chair in the manufacture of which time, labour and expense is reduced to a minimum.

In carrying into effect the foregoing and other objects hereinafter more fully dealt with the novel features of the device include a base plate adapted tobesecured on a railroad tie or the like, rolled to form channelled ridgesor walls thereon and provide therebetween a seat forthe'base of a rail, the walls being formed with bent portions relative to the channels and an opening through said portions and the base plate, a clamping member adapted for engagement with said opening while clamping the rail and resting upon the walls, and a locking pin carried by the walls for engagement with the clamping member whereby the latter is locked in position and whereby .on the bent portions being-clinched, the locking pin is retained in looking position.

. The invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof while the scope of the invention will be more particularly pointedout in the claims.

Referring now to the drawing and to the embodiment therein disclosed for illustrativepurposes and in which like numerals of reference indioate corresponding parts in each figure.

Fig. 1 is an end view partly in section of the device with a rail seated and clamped therein.

Fig. 2 is a plan view.

Fig. 3 is a detail of the clamping member or keeper.

Fig. 4 is a detail of the locking pin.

Fig. 5 is a modified form of the locking pin.

Fig. 6 is a modified form of the clamping member.

Referring now more particularly to the drawing, A, designates the base plate adapted by means of the holes 10, therein to be secured in well known manner to a railroad tie or the like. This plate is rolled from a bloom forming the transverse ridges l1, and 12, providing a space or seat 13, therebetween for the base 14, of a rail B. In short, a chair for the rail.

Instead of as heretofore in'device's of this description in which bolts or'the like were used to clamp the rail in the'chair, I provide channels 1'7, formedin the ridges or walls 11, and 12, and intermediately separated as at 18, to register with a 'hole 19, in the base plate hereinafter more fully referred to. The channels 17, are"also intermediately bent as at 21, and 22, on each side of thehole 19, to 'form lip portions 23. A'clamping member 24, "as here shown substantially T- shaped, fits into the opening 19, andin the stem 25, thereof is provided an opening or hole 26, while the inner surface'o'f the top conforms'as at 28, to'the topcontour of the rail base 29, and is adapted to fit loosely relative thereto, providing sufiicient space therebetween to eliminate undue stress on the locking means for said member hereinafter more fully referred to. Another-feature and a very important one in connection with this clamping or keeper member 24, is that it is reversible relative to the rail and the. walls or ridges l1, and 12, of the plate.

For locking the member 24, a key or 'pin'31, is provided which is slipped in-through thechannels 17, in the ridges 11, and 12,-and through the hole 26, in the member 24, while to retain this pin in looking position, 'the ends of the lips 23, are clinched or bent down as at 32, in any suitable manner when the locking pin'being of substantially the same length as these lipped or bent portions of the ridges or walls, it is thereby securely retained in position. To remove the pin, when replacing a rail, it is'only necessary to force it out in any well known manner. It should here be noted that this locking pin may be bent at one end toform a driving head and intermediately curved to provide spring action in the clamping-member and the bent walls. Furthermore, the fact that the locking pin loosely engages with the clamping member and rigidly engages with the walls or sides of the chair, permits play of the former to take up stress on the locking pin while providing for any wave motion of the members-involved.

In operation. The rail having been placed in theseat 13, between the ridges orwalls 1-1, and 12, on the base plate, and the clamping or keeper member placed in the hole 19, and the lip portions having already been clinched at one end as at 23, the locking pin 31, is inserted through the hole 26, the other ends of the lip or bent portions are then clinched, completing the operation.

The simplicity and effectiveness of this construction and the increased speed at which a rail can be placed in operative and secure position are results that could not be achieved with means heretofore or at present in use.

It will be seen from the foregoing that app-licant has developed a device of the character disclosed in which flexibility is provided for, as well as durability and economy in construction, thereby ensuring smooth and safe travel thereover.

Various forms of the apparatus described will suggest themselves to those skilled in the art; it is, therefore, not intended that the present application should be limited to any particular form of construction; modifications may be made in the apparatus above described within the scope of the claims, without departing from the spirit or scope thereof.

What I claim for my invention is:

1. A rail chair comprising a plate formed with spaced transverse ridges adapted to hold therebetween a rail, clamping members co-operative with the plate and arranged to extend into the ridges and the plate, securing means for holding the clamping members in flexible relationship with the rail, and means formed in the top surfaces of the ridges for holding the securing means.

2. A rail chair comprising a plate formed with spaced transverse walls, formed with recesses in the top surfaces thereof, a clamping member adapted for engagement with the rail, the walls and said plate formed with an opening therethrough, a detachable pin located in the recesses in the top of the walls for flexibly locking the clamping member in position.

3. A rail chair comprising a base-plate formed with spaced parallel walls having recesses in the top thereof adapted to house securing means, clamping members formed for simultaneous engagement with a rail between the walls, the base plate and the walls, locking means, for flexibly locking the clamping members, located in said recesses and adapted to maintain the clamping members in yieldable engagement with the rail.

4.
