RAIL-JOINT.

SPECIFICATION forming part of Letters Patent No. 673,811, dated May 7, 1901.

Application filed September 28, 1900. l'i l N 31,43 '7. (No model.)

To ztZZ whom it may concern.-

Be it known that I, ADDISON BARR, of Martins Ferry, in the county of Belmont and State of Ohio, have invented a new and Improved Rail-Joint, of which the following is a specification.

This invention relates to improvements in that type of rail-joints in which the rail-sections are connected by tie or fish plates havro ing members adapted to interlock with the rail-sections; and my said invention seeks to provide a rail-joint of the character stated of a very simple, economical, and stable construction in which the several parts can be r 5 readily assembled and which will effectively serve to keep the rail-sections joined without the use of bolt and nut lock devices such as are commonly employed.

My invention in its complete makeup also includes a novel combined wedge-and-lock member for holding the fish-plates from longitudinal displacement and also to cause them to bear closely up against the under face of the tread or head portions of the rail in such manner as to resist the downward strain on the rail and disseminate said strain over a. greater base-surface than ordinarily and to provide a firm bearing for the rail and maintain a rigid joining of the rail ends, whereby to reduce the rail vibration and rattling to the minimum.

In its subordinate features my invention consists in certain details of construction and peculiar combination of parts, all of which will hereinafter be fully explained, and particularly pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of my improved rail-joint construction. Fig. 2 isaplan View thereof. Fig. 3 is a cross-section taken on the line 3 3 of Fig. 2. Fig. 4 is a similar view on the line 4: 4 of Fig. 2. Figs. 5, 6, and 7 are respectively detail views of the wedgeplate, the fish or tie plate, and a portion of one of the rail-sections. Fig. 8 is a plan view of the modified form of my invention; and Fig. 9 is a transverse section thereof, taken on the line 9 9 of Fig. 8.

Referring to the accompanying drawings, in which like characters indicate like parts in all the figures, 1 1 indicate the ends of the two rail-sections of the ordinary type, and each section has its web portion 1 made solid1l. e., the same is not provided with the usual bolt-aperture. At a point near the end each section 1 has its foot or base flange 1 formed with a vertically-disposed elongated slot 1, the purpose of which will presently appear.

2 2 designate the tie or fish plates, having the usual cross-sectional shape, as shown, and each plate 2 has a pair of pendent lugs 2, adapted to interlock with the slots 1 in the adjacent ends of the rail-sections, said lugs being of a slightly less length than that of the slots to provide for the usual expansion and contraction of the rail ends.

It will be noticed by reference to Fig. 4 the front edges 0 of the slots 1 are slightly undercutor beveled outwardly and the outer faces a of the lugs 2 are likewise inclined, so that the said lugs will the more firmly engage or interlock with the rail-flanges when the plates 2 are forced up in the manner presently eX- plained and whereby said lugs 2 will be held from transverse play in the slots 1 and rattling of the parts or loose play prevented.

3 3 designate a pair of wedge-plates, one for each fish-plate 2, that cooperate with said fishplates and the rail. The plates 3 primarily serve to hold the fish-plates in such contact with the rail-sections and in such manner as to positively hold them from playing loosely on the rails and also for supporting the head 8 or tread part of the rails, so that the stress or strain on the rail will be disseminated from the said head directly against the base or flanges of the rail instead of entirely through the web to the base, as is commonly the case.

By referring now more particularly to Fig.

3 it will be noticed the wedge members 3 when drawn under the plates 2 will cause their upper edges 2 to bear against the head parts 1 of the rail at diverging angles (see dotted linesy y in Fig. 3) rather than in avertical plane and at the same time cause said plates to firmly interlock or bear against the rail-head and the base-flanges at the points a, b and in such Way that all danger of rat- Ioo tling or vibrating action is overcome. Each wedge-plate 3 has edge recesses 3 to lap over ing the fish-plates to engage the rail-sections in the manner shown the downward strain of load passing over the rails is the more uniforn1ly distributed, and by reason of the tight clamping of the fish-plates against the rail said rails are reinforced and kept rigidly joined.

The construction of parts is very simple and the cost of joint not greater than the ordinary nut-and-bolt joints, as the wedges can be made for less cost than the ordinary bolt and nut lock devices, it being understood that the rail-body is weakened less by making a slot in it at the base, as in my case, than is the case when the web is apertured to receive the lock-bolt.

In Figs. 8 and 9 I have illustrated a modification of my invention, and in this form of my invention a keeper-plate 10 is provided having a rhomboidal shape and a length somewhat greater than the width of the rail-base and the wedge-plates 3, the said plate 10 when cooperatively used with the wedge-plates 3 being passed transversely under the rail-base and held at right angles thereto, as clearly shown in Fig. 8. The extremities of the plate 10 are cut or slitted in lines parallel with their outer edges, the slit at one end being in a direction opposite to that at the other end, whereby lugs 10 can be bent up at such ends, which when bent up, as shown in Fig. 9, will act as a means for positively holding the wedge-plates 3 from becoming loosened or slipping outward, particularly so when the spikes become loose. The object in making the plate 10 of rhomboidal shape is to bring its ends to such an angle relatively to the wedge-plates 3 that when the said ends are bent over, as shown in Figs. 8 and 9, they will lap over said plates 3.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with the rail-sections, each having vertical slots in the base portion, said slots having one edge undercut, and the fish-plates having lugs to engage the notches, said lugs having their outer,ends inclined, and the said fish-plates having their upper ends formed to engage the head of the rail-sections, and means for forcing the said plates to press against the said heads at an obtuse angle thereof, for holding said plates to such position, substantially as shown and described.

2. The combination with the rails, and the fish-plates, having their upper ends formed to press against the head portions of the rails, and the wedge-plates 3, for engaging the railbase and the under edge of the fish-plates, said fish-plates and the wedge-plates having interlocking means for engaging each other, and means for holding the wedge-plates to their clamped position, substantially as shown.

3. The combination with the rail-sections, each having apertures in the base, and the fish-plates, said plates having their upper ends formed to engage the heads of the rails, and their lower ends provided with pendent lugs to fit the apertures in the rails, and the wedge-plates 3, for entering between the railbase and the bottom of the fish-plates, said wedge-plates having edge recesses to strad dle the fish-plate lugs, and means for holding the wedge-plates to their clamped position, substantially as shown and described.

4. The combination with the rail-sections, the fish-plates, and the wedge-plates arranged substantially as shown; of the plate 10, having a rhomboidal shape, its outer ends being slitted to provide bent lugs, the lug at one end extending in a direction opposite to the other, said lugs adapted when pressed down to lap over the top edge of the wedge-plates, their vertical portions being arranged to engage the outer edges of the said wedge-plates, for the purposes described.
