RAIL-CHAIR.

Specification of Letters Patent. Patented Sept. 2'7, 1921.,

Application filed March 8, 1921. Serial No. 450,561.

T all whom it may concern Belt known that I, DAVIS AMBRosE, a

- citizen of the United States, residing at Louisville, in the county of Jefferson ,and State of Kentucky, have invented new and useful Improvements in Rail-Chairs, of which the following is a specification.

My present invention has reference to an improved rail chair.

My primary object is to produce a rail chairconstructed of sections associated in such a manner that the bending of the rails downward will automatically cause a binding engagement between the chair and the said rails.

A further object is to produce a rail chair comprising essentially two members shaped to receive the rails therebetween, a wedge element resting on the base and underlying the rails in a manner that the bending of the rails on the wedge forces the latter against the base of the chair sections to cause a swinging or canting of the latter to bring their engaging portions into frictional contact with the flange and web of the rails, or with the base flange and side members of fish plates when the latter are employed, while novel means is provided for holding the wedge. between the chair and rails.

The foregoing, and other objects which will appear as the nature of the invention is better understood, may be accomplished by a. construction, combination and operative association of parts, such as is disclosed by the drawings which, accompany and which form part of this application.

In the drawings Figure 1 is a side elevation showing two rails secured to a rail chair in accordance with this invention.

Fig. 2 is a sectional view on the line 2-2 of Fig. 1.

Fig. 3 is a sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a sectional view on the line 44 of Fig. 1. V

Fig. 5 is a perspective view looking toward the widened end of the wedge.

Fig. 6 is a similar view of the locking plate for the chair sections.

Referring now to the drawings in detail, two rails, of the ordinary construction, are indicated by the numeral 1 respectively. The rails 1 are connected together by angle bars 2 which tion.

improved rail chair comprises two simi ar members or sectionseach having a substantially thickened block-like base 3 from which arises in a line with its outer edge, a side plate 4 that has its upper extremity formed with an inwardly directed are also of the usual construcflange 5. The under face of the flange 5 is arranged at an inclination, as indicated by the numeral 6; The chair. sections are of a less length than the angle bars 2 and the base portion 3 of each of thesections gradually decreases in thickness from one end to the other. This arrangement is made only in view of saving metal.

The inner confronting lower corners of the base portions 8 of the chair sections are rounded, as at. 8, which permits of a determined tilting or canting of the sections with respect to each other when the locking plate and key, hereinafter described, are removed. In this manner the chair sections may be readily arranged in rail engaging position. I

The base 8 of each of the chair sections has, approximately at the center theerof, a transverse slot 9 which enters from its outer face and which communicates with openings 10 in the portions of the base inward of the side members 4. The slots 9 are of a size to receive freely therethrough a locking plate 11. The plate 11 has its ends formed with extensions 12, the said extensions being spaced away from each other a distance to permit of the inner straight edges 13 thereof contacting with the outer straight faces of the side plates 4 of the respective chair sections, when the locking plate has been moved upwardly by a key 14 that is also passed through the slots 9 and has its upper edge contacting with the lower edge of the locking plate 11. Suitable securing means, preferably in the nature of cotter pins 15 pass'through openings in the key 14 for retaining the same on the chair.

The numeral 16 indicates the wedge which I employ. The wedge has its upper face flat, as indicated by the numeral 17, and its under and inclined face rounded downwardly from its edges to its center as indicated by the numeral 18. The rounded portion 18 of the wedge rests on the upper face of the base of the chair sections, and exerts a tight 3O mined outward pressure against the hooked frictional engagement between the said base through. These openings 20 receive therethrough rods 21 respectively. Each of the rods has a threaded end 22 on which is plate.

screwed a nut 23, each of the said nuts contacting one end of a convolute spring 24: that is arranged between the said nuts, and the projections or lugs 12 on the locking The threaded end of each of the rods 21 is provided with a series of apertures, and through one of these apertures there is passed a cotter pin 25 that contacts with the outer face of the nut to hold the nut from unscrewing. The opposite end of each of the rods 21 is bent at an angle, as indicated by the numeral 26 and is directed toward the wedge. The extremities of the angle ends 26 are bent upon themselves to provide hooks 27 that are received in the apertures 19 in the Wedge plate. By this means, it will be noted that the wedge is effectively sustained in wedging position, and it will also be apparent that a deterends of the rods will compress the springs to permit of the disengagement of the rods with the wedge plate, which permits of the said plate being forced from between the chair and rails, after the removal of the key 14 from the chair sections to permit of the removal of the rails from the chair. The rails are supported onties which are disposed to the opposite sides of the rail joint, and the vibration of the rolling stock passing over the rails at the joint willcause the railchair described and hold the confronting to automatically grip the rail, as heretofore ends of the rails in proper alinement.

Having described the invention, I claim 1. A rail chair, comprising two companion sections each including a base, upstanding flanges at the upper edges thereof providing side plates and inwardlydirected' flanges on the upper edges of the said side plates, removable means connecting the bases of the chair sections for holding the chair in rail receiving position, awedge member hav ing a rounded lower face between the base of the rails and the base of the chair sections, and spring influenced means between the wedge and the connecting means for the chair sections for securing the wedge on the chair and in frictional engagement with the base of the rails.

2. In combination with two connected rails, of a rail chair therefor, comp-rising two similar sections each including a base, "a side and an inturned flange formed-on the side, the base portions of the chairs decreasing in thickness from one end thereofto the other end, the bases of said chairs having of the chair sections and the base of the rails, and spring influenced means between the widened end of the wedge and the ends of the locking plate for holding the wedge in wedging position with respect to the chair and with respectto the rails.

y In testimony whereof I aflix m DAVIS A BROSE.
