JERQIVEE T. BIGGONIGAL, OF POTTEBSDALE, PENNSYLVANIA, ASSIGNOR OE ONE-HALF TO THOMAS BOWMAN, OF CLEARFIELD, PENNSYLVANIA.

RAILWAY-TIE PLATE.

Application filed February 6, 1915.

To all whom it may concern Be it known that I, JEROME T. MoGoNI- GAL, a citizen of the United States, residing at Pottersdale, in the county of Clearfield and State of Pennsylvania, have invented a new and useful Railway-Tie Plate; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved railway tie plate.

As an object of the invention it is the aim to provide a tie plate, more particularly designed for use in connection with the tie illustrated, set forth and claimed in the U. S. patent issued on Sept. 23 1913, to Jerome Thomas McGonigal Patent No. 1,073,773.

Another object of the invention is to provide a tie plate, so mounted on the tie, so as to permit the rails to tilt toward one another, thereby obviating spreading of the rails.

One of the features of the invention is to provide round cork plates, in other words, cylindrical cork plates between the tie plate and the tie, said cylindrical or round cork plates acting to prevent the tie plates from creeping and the rails from spreadmg.

Another feature of the invention is that the outer portion of each tie plate is firmly supported, while its inner end is yieldably supported, thereby permitting the tie plates to tilt inwardly toward each other, said rails likewise tilting, so that the car wheels will firmly engage the rails.

Another feature of the invention is that the cylindrical or round cork plates do not cut the tie and thereby maintain the rail way true to gage.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a sectional view, through a tie, showing two tie plates applied, and supporting rails. Fig. 2 is a detail perspective view of one of the tie plates. Fig. 3 is a plan view of one of the Specification of Letters Patent.

rails and the tie plate mounted on the tie. Fig. 4 is a view partly in elevation and partly in section of a modified form of tie plate. Fig. 5 is a detail perspective view of the tie plate shown in Fig. 4.

Referring more particularly to the drawings, l designates the railway tie, and 2 the rails. Between each rail and the tie is a tie plate 3. Each tie plate is provided with a recess 4 including the adjoining shoulders 5, in which recess and against the shoulders 5 the opposite edges of the base 6 of each rail engage, so as to hold said rail in place. The tie plates are provided with openings 7, for the reception of spikes or other suitable means 8 for holding the tie plates in position, said spikes extending into the ties as shown.

The outer portions of the tie upon its upper surface is provided with raised parts 9, to support the outer portions of said tie plates. Between the inner portions of said tie plates and the upper face of the tie, a composition of cork and asbestos and rubber 10 is interposed. This composition is substantial and firm, yet of a nature to permit the inner ends of the tie plates to slightly yield downwardly, thereby permitting the tie plates to slightly tilt and the rails to correspondingly tilt, whereby the car wheels will firmly remain in contact with said rails.

Securely fixed in any suitable manner in recesses 11 of the under portions of the tie plates are cylindrical or round cork plates 12, the lower portions of which are rounded as shown at 13, in order to engage correspondingly shaped recesses 1a in said tie. These cylindrical or round cork plates act to prevent the tie plates from creeping, and the rails from spreading, and maintaining the railway true to gage. Said cylindrical or round cork plates are detachable or removable, thereby rendering them replaceable or renewable.

In Fig. 4 the composition of cork and asbestos (which is shown at 10 in Fig. 1) has been eliminated. Also in Fig. 5 only one shoulder 5 has been used, it being noted that one shoulder will act just as well as two shoulders.

The invention having been set forth, what is claimed as new and useful is 1. In combination with a railway tie having its upper surface adjacent the outer ends of the tie provided with raised portions, a

rail supporting tie plate having its outer portion engaging and resting upon said raised portion, a composition filler between the inner end of each tie plate and the tie, means for anchoring the tie plate and its rail in place, and cylindrical or round cork plates carried by each tie plate and embed ding in the tie to prevent creeping of the tie plate and the spreading of the rails.

2. In combination With a tie and railway rails, a supporting tie plate between each rail and the tie and provided with a recess to receive each rail, the outer end portion of each tie plate engaging and resting upon the upper outer portion or face of the tie, a substantial yet yieldable composition filler between the inner end of each tie plate and the tie, means for anchoring each tie plate and the rail in place, removable and replaceable cylindrical or round cork plates carried by the under face of each tie plate said tie having recesses corresponding in shape to the cylindrical or round cork plates to receive them, so as to prevent creeping of the tie plates and spreading of said rails.

In testimony whereof I have signed my name to this specification in the presence of two, subscribing witnesses. JEROME T. MOGONIGAL. Witnesses H. B. HAR SMID, JOHN H. MOORE.
