Beit known that I, CAnMAN M. SIMPSON, a citizen o'l .the United States oi America, re siding' at illillvale, in the count-y of Allegheny and State ol Pennsylvania, have invented certain new and uselul lniprmeinents in Rails, ol" which the following,` is a specification, rel'crence beingr had therein to the accompanying drawings.

This invention vrelates` to certain new and useful improvements in rails; and the priniary ohject oll the invention is to provide a novel l'orin ol" rail which will he practically jointless. VIn this connection l have devised a rail particularly adapted for steam, electric, or train railways, and in construct inf; my iniprovved rail lorni the saine ol' a plurality ol sections which-are joined together to provide a continuous tread lor rolling-stock that passes over the saine. l have aimed to pron vide a rail the tread or hcadot which can he easily and quickly renewed at any desired time without removing the entire rail.

It is a. well-known fact that considerable trouble is experienced in removingr the ordi nary spikes to renew a section ot rail and also when a section has once been removed the saine spike-holes of the ties cannot he again used. rlhis permits water to enter the old holes in the tie and in the course ot time renders the tie useless. By iny improved jointloss rail it will not he necessary to reinove the spilies ol" a rail when it is desired to renew the wearing-surface or head of the rail, and in this nianner a great saving is accomplished in the ties by increasing the longevity oi the saine. l have made allowances 'for the expansion and contraction of my improved rail, and the detail construction of the rail will be hereinafter more fully described andl claimed. i

-Referring to the drawings acoinpanying this application, like nunierals of reference designate corresponding parts throughout Figure 1 is a side elevation oi'a portion oi a rail. Fig. '2 is a longitudinal sectional View of the saine. Fig. 3 1s a cross-sectional view taken on the line t o; of Fig. 1. Fig. 4 is a perspective View olE a portion of a rail. Fig'. 5 is a similar View of the tread-seetion of the rail, and 6 is a similar View of the basesection oi the rail.

To put iny invention into practice, 1 conn struct my improved rails of a plurality of sections, said sections being joined together at places throughout the rail to l'orni practically a jointless rail. In Fig. 1 ol" the drawings i have illustrated a portion et a rail wherein two tread-sections l l are shown and three hase-sections 2 2 2. The base-sections consist ot base-llanges 3 3 and upwardly-extending parallel weh-flanges 4 4, said flanges being provided with aliningr openings or slots 5 5 at their ends and 6 6 intermediate their ends.

The tread-sections 1 consist of a web 'portion 8 and a head or tread portion 9, said head or tread portion heilig' similar to the ordinary type ol rail at present used. 'lf he wel) portions of the sections 1 are provided viirh elongated lopenings or slots 10 1() adjacent to their ends and 11 ll intermediatetheir ends.

ln asseinhling?r the sections oi` a rail the hase-sections .2 l .2 are secured to the tics or foundation upon which the rail is to oe laid, the. sections being arranged end to end to ylorin a continuous hase-section. The head or tread sections are then placed in the hasesections, the web portions 8 of the sections 1 extendingr downwardly between. the wel)- langes 4t 4 ot' the sections '2, the heads or treads Qo'll the sections 1 'resting upon the top edges ot the weh-llanges 4 4 of the sections 2. In placing` the head or tread sections 1 1 in the hasc-seet ions l the sections l are arranged whereby their confronting ends will ineet intermediate or centrally el" the sections 2, thereby providing ar lirin and jointless hase for the, confront-ingr ends oi' 'the sections 1 1 and a irxn and solid head or tread for the confronting ends of the sections l it will thus he observed that the joints of the ditierent sections throughout the rail are'alternate, first one ioint being formed'in the sections 2 and then a joint in the sections 1.

To hold the sections 1 1 within the sections 3 2, nuts and holts 14 are employed, and these bolts are placed in the openings of the haseseetions l to engage in the openings or slots of the sect-ions 1. The openings or slots 10 1t) and 11 11 of the sections 1 are adapted to register with the openings 6 6 and 5 5 of the web-flanges Lift of the sections 2. this manner each section i will he locked at two places to the sections 2, and it will be imposot its adjoining sec-tions or the base-section which supports saiil sections. v

By toi-ming a rail of a plurality of sections l which are joined together in the manner just TOO sible for one section 1 to move independently 'described it is possible to renew the tread 'or head sections of the rail Without removing the spikes that retain the base-sections in engagement with the ties or foundation upon which. they are mounted, it only heilig necessary to remove the bolts and nuts 14 oi the base-soetions in order to remove any head or -using the base portions of a rail for possibly a plurality of head-sections, and in this connection l. desire again to call attention to the fact that a great Saving is incurred in the ties or' foundations which support my improved rails.

I have allowed for the expansion and contraction ofthe sections of the rails by providing the elongated openings or slots 1() 1l), l1 11, 5 5, and 6 in the sections of the rail, these opei'iings permitting 'of one section to expand and contract relative to its adjoining section.

,lt will be observed in Fig. 4 oi the drawings that l have formed one of the head-see tions l integral with the base-section, thus providing a rail whi'eh can be easily used in conneetion with a switch or frog, the base portionioi the rail only being dispensed with for a portion el' its length` in order that it may be secured to my improved rail-sections.

l do not care to confine n'iyscll to ar, y speeilie means ol' seeurii'ig the base-Sections to the ties or i'mindations which support them, and such changes in the construction of my improved rails as are permissible by the appended claims may be resortedl to without departing from the spirit and scope of the invention.

What I elaiimand desire to secure by'Letters Patent, is

1. A rail of the type described, consisting of a plurality of base-sections, a plurality of separate head or tread sections, certain of said base-sections being formed with vertical web-flanges havin vertical openings formed therein, said treat -sections having web portions adapted to fit in the vertical openin sin the base-sections, certain other of said base-sections 'being formed with integral heads for a portion of their length and said integral heads and the Web-flanges of the last-named sections being prolonged beyond the base-flanges thereof and seating in the vertical openings in the web-flanges of the -first-named base-sections.v

2. A rail of the type described, consisting of a base-section, having a web-flange with a yvertical opening therein, and a base-section having an integral web and tread portieri, the web and tread portion of the last-named section being prolonged beyond the baselanges thereof, and the said prolonged web portion seating in the vertical opening in the web-flange of the lirst-nanied section.

ln testimony whereof l aiiix my signature in the presence of two Witnesses.

CARMAN M. SIMPSON.
