No. 520,534. Patented May 29, 1894;

NIT-ED STATES AMOS F. NAYLOR, OF BRANDYWINE HUNDRED, DELAWARE.

RAILROAD-CHAIR.

SPECIFICATION forming part of Letters Patent No. 520,534, dated May 29, 18 Applieation filed November 6, 1893- Serial No. 490,088. (No model.)

To to whom it may concern:

Be it known that I, AMos F. NAYLOR, of Brandywine Hundred, in the county of New Castle and State of Delaware, have invented certain new and useful Improvements in Railroad-Chairs, of which the following is a specification.

The improved chairis illustrated in the accompanying drawings, wherein Figure 1, is a perspective view of the chair showing the meeting ends of two rails located therein, and the keys for holding the rails in position. Fig. 2, is a perspective view of the chair. Fig. 3, is a perspective view of one of the fastening keys. Fig. 4, is a longitudinal vertical section through the chair and the rails therein.

A, B, are portions of two rails, each of which as usual has a base a, a tread b, and a web 0.

O, is the chair which has a central depressed channel at of the same width as the base a. of the rail, vertical longitudinal ribs 6, e, horizontal ledges ff between the ribs e eand channel d, overhanging flanges g g extending inwardly from the ribs e 6 respectively and overhanging the ledges f f, respectively, whereby longitudinal rectangular grooves h h are formed between the said flanges and ledges, studs 63' extending upwardly from the channel d, and external fastening flanges k is formed with suitable provisions (such as boltholesZ Z) for securing the chair to the ties or other part of the road-bed. -The grooves h 71. do not extend the whole length of the chair and are open at one end only so that registering stopsm are thereby formed. The chair with all its described accessories is preferably formed of a singe piece of metal. The rails have at their adjoining ends recesses 12 0 which fit over the studs z'j respectively, so that the rails are thus properly positioned. When the rails are in place in the chair their bases fit in the channel 61 and the upper faces of their bases where contiguous to the ledges 5 ff are on a level therewith.

D, D, are the fastening keys two in number, each as long as thechair. Each key rests directly on the base of the rail and against its web, and each key has a flange p which fits snugly under and entirely within the tread of the rail, thereby supporting the tread and at the same time being out of reach of the 'studj in'Fig. 4.,is shown in dotted lines.

wheel flanges; a rectangular tongue g which fits in one of the rectangular grooves h; and a vertical shoulder 1" which fits against the vertical inner wall of the chair flange g. In other words, when the key is in place it fills all the space between the chair and one side of the rail. The tongue q of the key does not extend the full length of the key, but has a recessed shoulder s which abuts against the stop m on the chair. The shoulder s and stop an insure the proper position of the key so that the bolt-holes t with which it is provided may register with the bolt-holes a o in the rails. These keys D, it'will be noted, perform the function of ordinary fish plates. Each key with its accessories is made of a single piece of metal.

E, E, are bolts for fastening the keys to the rails, and which extend through the boltholes to o.

This improved chair with its fastening keys makes an eifective and perfect rail joint. The rails and fastening keys are properly and readily positioned. The rails are held firmly both laterally and vertically so that there is no seesawing of the joint. The distance between the fianges g g is as great, at least, as the width of the rail base a, so that the rail can be simply dropped into place. The keys are easily slid in and out of position, thus facilitating the laying and replacing of the rails.

Several features illustrated in the drawings are susceptible of modification. The chair is shown as provided with bolt-holes for fastening it to two adjacent ties soas to form a suspension joint, but this is not essential. The chair is shown provided with two studs Z 7, whereas one of the studs, as j, may be omitted. To indicate this possible omission, tlfe l1 case both studs 1, j are employed, it is usually desirable that one of the rail recesses, as 0, should be elongated to provide for expansion and contraction. The bolt-holes no of the rails are, as is customary, shown elongated, but this is not necessary when the rail recess, as n, fits closely over the stud, as "i, and to indicate that in such case the elongation is un= necessary the elongation of the bolt-holed is shown in Fig. 4, in dotted lines. More than two bolts E, E, can be used,but one of the advantages of the invention is that two bolts are all that are necessary, and hence two boltholes only are shown.

I claim as my invention 1. A railroad rail having base, web, tread, and recess in the bottom of its base, a rail chair having a central depressed channel (1 of thesame width as the rail base, vertical ribs e e on either side of said channel, horizontal ledges f f between said channel and said ribs e e respectively, the surfaces of said ledges being flush with the upper surface of the rail base, overhanging flanges g g extending inwardly from said ribs 6 e whereby rectangular longitudinal grooves h h are formed between said flanges and said ledges, said flanges g g having vertical inner walls and the distance between said inner walls being as great at least as the width of said channel (1, and a stud '21 projecting upwardly from the face of said channel and engaging the recess in the bottom of the rail,in combination with fastening keys D, D, which occupy the space between the rail on each side thereof and said chair, each key seating directly upon the rail base, and each key having a longitudinal flange p which fits under the rail tread, a longitudinal rectangular tongue g which fits in one of said grooves h, and a longitudinal vertical shoulder 0" which fits against the inner vertical wall of one of 'said flanges g,substantially as set forth.

2. Two abutting rails, each having base, web, tread, and a bolt-hole, and one at least having a recess in the bottom of its base, a rail chair having a central depressed channel d of the same width as the rail base, vertical ribs e e on either side of said channel, hori-. zontal ledges f f between said channel and said ribs respectively, the surfaces of said ledges being flush with the upper surfaces of the rail bases, overhanging flanges g g extending inwardly from said ribs 6 6 whereby rectangularlongitudinal grooves h h are formed between said flanges and said ledges, said grooves however being of a length less than the length of the chair so that a registering stop an is formed at one end of each groove, said flanges g g also having vertical walls which are separated by a space as w1d e at least as said channel (1, and a stud z pro3ecting upwardly from the face of said channel and engaging the recess in the bottom of the rail provided with a recess, in combination with fastening keys D, D, which occupy the space between the rails on each side thereof and the chair,'each key seating directly upon the bases of the two rails, each key having a I longitudinal flange p which fits under the treads of the rails, said flange having boltholes which register with the bolt-holes in the rails, each key having a longitudinal rectof a length less than the angular tongue q so that a recessed shoulder length of the key,

sis formed at one end thereof, said tongue fitting in one of said grooves h with its shoulder abutting against one of said registering stops m, and each of said keys having a longitudinal vertical shoulderr which fits against the inner vertical wall of one of said flanges g, and bolts which extend through the boltholes in said keys and rails, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

AMOS F. NAYLOR. Witnesses:

HENRY C. CONRAD, THOMAS GIFFIN.
