RAIL-JOINT.

To all whom it may concern.

Be it known that I, REUBEN W. SMITH, a citizen of the United States, residing at West Collingswood, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to an improvement in rail joints having for its primary objects the provision of means for more eifectually fastening a rail joint to track ties to prevent creeping of the track, and also for more uniformly distributing the wheel loads through the joints to the ties and road-bed.

To this end, the invention consists in the novel construction, combination, and ar rangement of parts hereinafter described, illustrated, and claimed.

The invention may be embodied in different forms of rail joints without departing from the spirit or principle thereof, so for illustrative purposes, several practical embodiments are shown in the accompanying drawings, in which Figure 1 is a sectional perspective view of a rail joint of the continuous type modified to include the novel improvement of the present invention.

Fig. 2 is a similar view of the Weber type of rail joint likewise modified to include the present invention. 7

Like reference characters designate corresponding parts in the several figures of the drawings.

In all of its adaptations to difierent types of rail joints, the distinctive feature of the improvement remains the same, namely, that of providing the joint with a railsupporting base member having a more extended area than the length of the joint, so as to overlie and secure support from other ties of the road-bed in addition to the joint ties.

Illustrating the invention in its application to a rail joint of the continuous type, it will be observed by reference to Fig. 1 of the drawings that the rail joint proper includes the usual'rails 11 and the opposite separately applied adjustable splicing or side joint bars 22, combined with the usual adjusting and clamping joint bolts, and with the usual joint ties 3 of the roadbed. In this type of joint, the side joint bars 2 are of standard length, and usually Patented Apr. 3th, 191%..

Application filed December 23, 1913. Serial No. 808,472.

spanning the two joint ties which are located under the end portions of the joint proper, although it is understood that sometimes a third joint tie is placed under the center of the joint where conditions or 1ocations make this desirable.

However, according to the present invention, no change or alteration is involved in the usual mounting of the joint proper upon the usual joint ties 3, nor in the fastening down of the joint bars or plates to the said ties, but the present invention supplies to the joint an increase in the base supporting area thereof and multiplication of the track fastening positions therefor. This is accomplished by means of constructing the rail supporting base member t of the joint with end extension plates 5. These plates are of suflicient length and projection beyond the ends of the side members of the joint, so as to overlie the next adjacent ties 6 beyond the joint ties 8. In this application of the invention to the continuous type of rail joint, the end extension plates are preferably rolled integrally with the main base member 4 of each joint bar 2, and each of said plates is formed with a spike hole 7 therein for receiving a supplemental fastening spike which is driven into the said extra joint supporting tie 6. Accordingly, it will be observed that a rail joint of the continuous type constructed in accordance with the present invention has each of its side members or bars provided with a pair of end extension plates 5 respectively projecting beyond opposite ends of the joint, and thus affording a construction which carries out the objects of the present invention in a most effectual manner.

Referring to the adaptation of the invention to the Weber type of rail joint, reference is made to Fig. 2 of the drawings. As shown therein, this type of joint includes in combination with the rails, the standard features of a plain angle bar 8 at. one side of the joint, the channel bar 9 at theopposite side of the joint, the shoe angle 10 having the upright member 11 and a base member 12, and a wooden or compressible filler block 13 interposed between said upright member 11 and the outer side of the channel bar. The rail-supporting base member 12 of the shoe angle extends entirely beneath the rail bases, and is formed with end extension plates 5 which are of suflicient length and projection beyond both ends of the side members of the joint so as to overlie the next, adjacent ties 6 beyond the main joint ties 3, said, end extension plates 5? having formed therein the spike'holes 7 a to receive the fastening spikes which supplement the main fastening spikes which engage the joint ties.

From the'foregoing, it will be observed that all forms of the invention preserve the same structural and functional characteristics,that is, base members having end extension plates Which extend beyond both ends of the side joint members or bars so as to overlie and secure support from other ties beyond the joint ties.

Having described the essential and distinct structural features of the present invention, special attention is now drawn to the two-fold object attained thereby. First,

to ofier facilities for spiking, or otherwise fastening, the joint structure more securely to the ties, in order to keep the track from creeping. In all railroad track there is a tendency under certain conditions of traffic,

7 wheel-loads, track maintenance and road-bed construction, forthe rails to run or creep longitudinally, usually in the directionof traflic. This creeping is resisted only by the friction of the rails on the ties and by means of spiking the joint plates, through slots in the plates, to the ties, the spikes and the joint-bolts Working together to hold the rails in proper position on the ties. This creeping force, however, is frequently sufficient, when the, joint structure is fastened to only tvvoor three ties, to drag the joint ties out of position in the direction of thecreeping of the rails, thus disturbing the road-bed and giving thejoint an unstable support. This shifting of the ties and disturbing of the roadbed also cause bad alinement and unevenness of surface of the track, and various s e-called anti-creeper devices are in use to prevent or to diminish creeping of the rails.

By means of the present invention, the base portion of the joint is fastened, as herein set forth, by means of spikes to the additional ties 6 beyond the joint ties proper, and consequently thev resistance offered to the creeping movement of the rails is increased proportionately to the number of ties covered by the base plate, and the disturbing efiects on the road-bed are thus materially diminished.

Second, to distribute the wheel loads more uniformly through the joint to the ties and road-bed. By extending the base portion of the joint over the additional ties as shown, the wheel loads at the rail ends are not concentrated on the two joint ties alone, but are distributed to adjacent ties, thus diminishing the disturbing effects of the heavy wheel loads on the road-bed, and securing the bencficial effects of a longer joint bearing on the ties, Without the increased cost incident to increasing the length of the whole joint structure.

From the foregoing, it is thought that the construction and many advantages of the hereindescribed rail joint will be readily apparent without further explanation, and it is also. to be understood that changes in the form, proportion, and minor details of con struction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

I claim:

1. An anti-creepingrail joint comprising in combination witha plurality of track ties, the rails and the joint bolts, of a joint bar clamped in the fishing spaces of the rails by the joint bolts and provided with an integral inwardly extending base plate extending free of and beyond the ends of the bar and fastened to the ties beyond the joint ties.

2. An anticreeping rail joint comprising in combination with a plurality of track ties, the rails and joint bolts, of an upright joint bar secured to the rails by the joint bolts and provided with an integral base plate underlying the rails and extending free of and beyond the ends of the bar and fastened to the ties beyond the joint ties.

In testimony whereof I hereunto afiix my signature in the presence of two Witnesses.
