RAILWAY-RAIL JOINT.

Application mea November e, 1925. serial Na 67,440.

To all 107mm t may concern:

Be it known that I, LUTHER SMITH, ay citizen of the United States, residing at Norristown, in the County of Montgomery and StateV of Pennsylvania, have invented certain newv and useful- Improvements in Railway-Rail Joints, of`whi`chthe follow'- ing is a specification.

rl`his invention relates to certain newua-ndA useful improvements in. railwayA rail joints', and in railway chairs' usedy in connection therewith.

One of the objects of my invention is to provide'meaus for so supporting the confronting ends of the rails attheir point of junction as to form a. smooth continuous track and overcome the tendency tofsag at that point', and thusto obviate the necessity' of constant repairs.

Another object of my invention isto so connect together the rails at the point of juncture aste avoid the possibility oftheir working loose at that point.

A further Volcjecty of my inventionis-to so construct the rails' and the chair in which they are placed as to strongly and durably support their ends and thus give them llong life at the point where they are now most inclined to wear.

"With these and other objects? in view which may be incident to my improvements7 the inventionconsists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention,l may be varied! in construction, proportions and arrangement,` without de'- partino' from the spirit andscope of'the appen ed claims;

In order to make my invention more clearly understood, I haveishown in thelaccoinpanying; druvings.v means? for;l carrying the same into practical-eect-without limit'- ing the improvements in the-ir useful applications to` the particular constructions, which Ifor the lpurpose-"of explanation, have beenmade the subject of iillustration.V

Fig. 8 is a.' perspective view ofthe joint orchair in which` the rail ends fit and are locked; and

Fig. 9 is a vertical, central longitudinal view of the rail joint as it appears when assembled. v

Referring more particularly to Figs. 6 and 7', the 'numeral 1 refers tofonel en-dof a railway rail and the numeral 2 refers tothe end of another 'rail made inv accordancel with my design, and the. numerals 3k and 4 refer to the confronting ends of said rails which are adapted to he locke-d together, as will more fully hereinafter appear. 4Each end of each rail/ is made precisely alike so as to permit of the use ofeither end while-they are 'being laid, and as a description of one of them only is necessary, the other will .notbe particularlyk referred to' at this' time.

The web ofthefrailend, asv seen in Figures 6 and 7, is lprovided with a kerf 5 extending across the end, andjust `'loeyond'this kerf is a square opening 6 extending..` 4 partially through,l and the lower edge of the web, for a distance correspondingto the length ofthis opening, is=beveledasfat 7 Beyond this-peint` and'to-wards the farther end of the V weh andon -theunder side-thereof, the body' is provided.-VV with `,a c lepending,` retaining, or locking lug, 9-v adapted toy fit in a hole l0 in the hottomfofther rail cha-irVV 11 (See Fig.. 9) and aslight distance. beyondthis point is` a looss12.v extendingzout fromthe raillweb-and lewer-l part'of-thei Crown lil-*of the rail and integral therewith. This boss 12 on the end facing the confronting rail is provided with a socket 13 which forms a seat for the reception of a bolt to be presently described.

Referring to the perspective views shown in Figures 1 and 8, we see a railroad chair comprising a base 11 and a body 1/l integral therewith, the former provided with spike holes 17 for the reception ot the spikes whereby the chair is fastened to the railroad ties. The body has a horizontal slot 18 see Fig. S) for the reception of that part or" the web of the rail heretofore described and on the further side of the chair there is a strengthening and supporting rib 19 eX- tendin the length o't the rail chair and upon which the car wheel is largely supported as it passes over the juncture of the rails,`the rib being made to extend up even withV the crown 13 of the rail.

The central portion of the body ot the chair is not so thick as the end portions, the

Vpart numbered I19 being provided with apertures at 2O and 21 (See Fig. 2) for the reception of side locking pins 24 and 25. The outer ends of thes pins are each provided with a spike head 26, the other end 'of said pins being squared od as at 27 (except on its upper side 32) to form a locking or bolt head, and the body of the pin is surrounded by a spiral spring 28. `The pur pose of the spring is to push the pin inwardly and drive its square head into the hole or orifice 6 shown in Fig. 6, which forms its seat.

lin order to unlock this pin, the traclrman uses his pinch bar to force the head outwardly towards himself when the sameis withdrawn from its seat.

Referring again to the side locking pins 2-1 and 25, should it become necessary te remove the rails, it is to be noted that in replacing the rails, the downwardV pressure of the beveled edge 7 comes upon the rounded upper edge 82 ot' the lock head of the pin and by reason of the contour of the lock head forces the pin outwardly against the pressure of the spiral spring, the latter receding unt-il the orifice 6 comes opposite and slightly below the lower edge of the lock head, when the spiral spring drives the locking pin back into its seat in the oriiice 6 in the web.

The numeral SO represents a central lock bar. lts body is -[iat and extends through the side of the vchair vat its center, and through each of the kerfs 5 in the ends of the respective rails. As seen in Fig. 2, after it passes through the web, it terminates in an elongated pin 31 having a hole 32 bored lierethrough near its end into which lits a cotter or other pin 33, the same standing in a recess Bf in the far side ot t-he chair. This central lockl bar lpasses thus through both sides of the chair and through the web of each rail and eiiectually locks both ends ot the rails and the chair together.

The side locking pins are located on the side of the chair facing the road bed between the rails and extend through that side ot the chair and partially into the web of the rail, but no provision is made Jfor like pins on the other side of the chair. j

The chair at each of its respective ends is provided with an integral block 35, as is more particularly seen in Figure 8, said blocks being provided with dovetail passages 36 extending longitudinally therein, in which slide the beveled edges of a bolt 37, the bolt being provided at one end with a head 38, beyond which is a spiral spring 39, the purpose of which latter is to push the bolt head into the seat 13 in the boss 12 shown in Figure 7 thus etfectually locking the ends of the chair to the rail.

From the above it will be seen that the chair is strongly spiked to the rail ties; that the web of' each rail at its end lits therein, its bottom is locked to the bottom oi the chair by the locking lug 9; the end of each rail is secured by the central locking pin 3U by the side locking pins 24 and 25, and the cha-ir itseli' is secured to the rails by the end locking bolts 37.

ln laying the track, the chair is put in its proper position and the confronting ends ot the opposite rails laid therein, the bolts 37 having iirst been pushed towards one another by means of the bolt, heads 88. rlhe depending lugs 9 on the rails tall into their proper recesses in the base of the chair and as soon as this occurs, the bolts 37 are automatically pushed home in the sockets 18 by the springs 39 and the chair is then spiked to the tie.

The central locking bar is then pushed in through one side of the chair, the kerts in the ends of the rails Vand through the other side of the chair and the Cotter pin inserted near the extreme end of the pin. In order to secure further rigidity', the lock` ing pins 24 and 25 are provided, which as seen in Fig. 1 extend partially through the web and add their strength to hold the rails down in place and to counteract the tendency of the rails to rise immediately after the passage ot the wheels of the cars over the Joint.

"When it is desired to remove the rails, the central locking bar 30 is removed, the trackman then uses his pinch bar to force the side pins 24; and 25 outwardly from their seats, the bolts 37 are withdrawn and the rails are littedfrom their positions in the chair.

W'hile I have shown and described the preferred embodiment of my invention, I wish it to be understood that l do not confine myself to the precise details of constructionherein set forth, by way ot illustration, as it is apparent that many changes and variations may be made therein, by those skilled in the art, without departing from the spirit ot the invention, or exceeding the scope of the appended claims.

I claim l. The combination with a railway chair, the side walls of which are apertured and the base of which is provided on either side ot' the center with an apertured seat, and railway rails, the confronting ends of which are slotted and adapted to lie within the chair, of a lug depending from each rail 1 and fitting wtihin the aperturedseats in the base of the chair, and a locking bar passing through the apertured side walls thereof and through the slotted ends of the rails to secure the chair and rails firmly together.

2. The combination with a railway chair, the side walls of which arev apertured at the center and one wall of which is apertured each side of the center, and railway rails adapted to lie in the chair, the confronting webs of which rails at each end are slotted and near the slot provided with a recess, orn a central locking bar passing through both apertured walls ot' the chair and the slotted ends of the rails, and side locking bolts located in the apertures on eac-h side of the center, the free ends of which lit into the recesses in the webs.

3. The combination with a railway chair .having apertured side walls, and provided near each end with integral blocks having depressed ways therein, and railway rails adapted to lie inthe chair, the confronting ends of which are slotted, an integral boss having a seat on each rail so constructed as to lie in place opposite the integral blocks of the chair, of a locking bar passing through the apertured walls of the chair and the slotted ends of the rails, bolts in the depressed ways of the integral blocks ot' the chair, the free ends of which pass into the-'bosses of the rails and lock the chair and rail securely together at the center and at cach end.

4. The combination with a railway chair having apertured side walls, integral blocks located near each end thereof, depressed ways therein, a base provided on each side ot' the center with an apertured seat, railway rails adapted to lie in the chair, the confronting ends of which are slotted, and an integral boss on each rail so constructed as to lie when in place opposite the integral blocks of the chair, of a locking bar passing through thev apertured walls of the chair and the slotted ends of the rails, bolt-s in the depressed ways of the integral bloc-ks on the chair, the free ends of which pass into thc bosses on the rails, and a lug depending from each rail and iitting` into the apertured seats in the base of the chair.

5. The combination with a railway chair, the side walls of which are apertured and the base of which is provided on either side of the center with an apertured seat, railway rails, the confronting ends of which are slottedv` adapted to lie within the chair, and a lug depending from each rail fitting within the apertured seats in the base of the chair, a locking bar passing through the apertured side walls and through the slotted ends of the rails to secure the chair and rails together, of a supporting rib extending the length oit one of the side walls and integral therewith, upon whichA the wheels of the car are carried without jolt over the juncture of the rails. In testimony whereof I aflix my signa ture.

LUTHER SMITH.
