MEANS OF FORMING JOINTS IN RAILS.

Specification of Letters Patent.

Patented Mar. 34), 1915.

Application filed June 2, 1913. Serial No. 771,238.

To all whom it may concern:

Be it known that I, HonA'rIo G. GILLMoR, a citizen of the United States, residing at Portsmouth, in the county of Norfolk, State of Virginia, have invented an Improvement in the Means of Forming Joints in Rails, of which the following is'a specification accompanied by drawings.

My invention'relates to railway rall joints, although the uses of the means employed to form the rail joints are not limited to such joints for my invention may be used 1n any connection in which it may be found applicable.

One of the objects of my invention 1s to provide an eflicient means for joining rails free from parts liable to work loose after having once been properly placed.

Another object of my invention is to provide such support for-the rail ends asto prevent deflections of the rails at the oint under the stresses due to the passing of the wheels.

To the accomplishment of these ob ects and such others as may hereinafter appear, as will be readily understood by those skilled in the art, the invention comprises a rail joint embodying the features of construction, combination of elements and arrangement of parts having the general mode of operation substantially as hereinafter described and claimed.

The preferred embodiment of the lnvention is shown in the accompanying drawings, in which Figure l is a side elevat on of the rail joint. Fig. 2 is a sectional view through the joint at the plane indicated by X 'X 1n Fig. 1. Fig. 3 is a section at the plane 1ndicated at X X in Fig. 1, showing one of the positions of the parts while the fish or angle bars are being drawn into place. Fig. 4 is a plan view of the oint.

Similar letters refer to similar parts throughout the drawings.

A represents the rails.

B represents a base plate, which ispreferably trough shaped wlth a recess 0 1n the top portion, the sides extending to form flanges P, which are recessed at the sides to receive the fish bars and form shoulders L to prevent longitudinal movement of the base plate. The bottom of the base plate 13 is provided with longitudinal ribs 0, preferably formed with cylindrical surfaces at D.

E represents fish or angle bars, which are constructed with flanges F and depending arms G, which depending arms are, at their lower edges, in section, hook shaped at H and arranged to engage with the ribs C of the base plate B. The depending portions G of the angle bars are so formed that when the lower portions H engage with the ribs C of the base plate B, the under surfaces of the flange F will engage with the upper surfaces of the base flanges of the rails at their outer edges as shown in Fig. 8.

I are bolts fitted with nuts K. Spikes M secure the rails and the parts of the joint to the ties N.

In assembling the parts, the base plate 13 is placed. The fish bars are then placed with the hook formed portion H of the depending arms G engaging with the ribs (J at the surfaces 1). The upper portions of the fish bars are then drawn toward one another until thebottom surfaces of the flanges F of the fish bars are in contact with the upper surfaces of the flanges of the rails A. The bolts I are then inserted and the nuts K put on and screwed up. The fish bars move angularly about axes in the ribs C and the positions of these axes are such that the angular movement of the fish bars about these axes, as the bolts are tightened, causes the fish bars to exert equal and opposite tension stress transversely upon the base plate and at the same time vertical stresses which press the base plate upwardly against the bottoms of the bases and the flanges F of the fish bar downwardly upon the tops of the base flanges of the rails, in such manner that the base flanges of the rails are firmly clamped. The re siliency of the material of which the bars E are constructed permits slight deformation and when the bars E are in their final position as shown in Fig. 1 they are, not onl engaging the under surfaces of the heads and upper surfaces of the base flanges of the rails, but are pressing the base plate firmly against the lower surfaces of the bases of the rails. The rails are therefore, as the bars E move angularly about the axes lying within the base, drawn into accurate vertical alinement and the several parts of the joint given such initial stresses that the stresses brought upon the joint as the wheels pass from one rail to the other are distributed among and resisted by the several parts without permitting the vertical movements of the rail ends which take place in rail joints as ordinarily constructed.

Obviously some features of the invention may be used without others and;theirnren-v tion may be embodied in widely varying forms Within the scope of the artisan.

Therefore without limiting the invention to the construction shownand described orenuinerating equivalents, I claim and desire to secure by Letters Patent the; following: 1. A sidebar forrail joints constructed 1 so as totengage a chair-below the rail-that rotational IHOVG'IHGIItS Of said ban-about an axis below-and betweenthe two edges thereof willforce surfaces of saidbar into engagement with the upper surfaeeof the base flange of the rail and thereby produce pressure ofsaid chair and bar uponthe rail base flange.

2. A rail joint-comprising-a-chair engaging thebottoni ofthe base flanges ofthe meeting ends ofrails-and'aside-bar so enbars. so engaging said chair atopposite-sides 0991:1101 this .patentmay. be; obtained for of the rails that rotation of said bars about axes below and between the edges of the rails willforce surfaces of said bars into engagement withthe upper surfaces of the rail base flanges and thereby produce upward pressure of said chair upon said rail 1 bases.

4. A rail: joint comprising the meeting rail ends, a base plate overlapping said rail ends and a fish bar-constructed to rotate about an axis below and "between the edges of the rail to produce transverse stresses in said base plate and verticalstressesof the base plate upwardly and of the fish bar downwardly upon the rail base-flanges.

5. A rail joint, comprising the rails, a 7

base plate engaging'w-ith the bases of said rails and side bars constructed to rotate about: axes lying below, at-opposite sides of and between the two edges of the rails, and producetransverse stress in said base plate and vertiealstresses of 'the base plate upwardly and of the side bars downwardly upon the rail base fl anges. r

In testimony that I: claim the foregoing as my invention I have-signed; this specification in the a presence oftwo subscribing witnesses. V
