Application filed October 9, 1914.

To all whom it may concern Be it known that I, MARCEL VITAS, a subject of the Emperor of Austria-Hungary, residing at Lucesoo, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Tie-Plates; 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.

his invention relates to new and useful improvements in tie plates, and has for its principal object to provide a tie plate which will effectively hold a railroad rail at the desired gage.

Another object of the invention is to provide a device which will permit the rails to be straightened and secured at the desired gage at a minimum amount of labor.

A further object of the invention is to provide a tie plate which will prevent rails from spreading and endangering the lives of passengers of trains passing thereover or property.

With these and other objects in view, the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specification and accompanying drawings, in which,

Figure 1 is a top plan view of the tie plate constructed in accordance with this invention showing the same with the rail re moved, and Fig. 2 is a longitudinal sectional view taken on line 2-2 of Fig. 1 and showing the same with the rail in place.

eferring now to the drawings by characters of reference, the numeral 1 designates the tie of the usual construction to which the lower tie plate, designated by the numeral 2, is secured. This lower tie plate comprises the body 3 which is preferably rectangular in form and is provided near one edge with the downwardly extending rib 4 which is arranged to engage the upper surface of the tie and hold the plate firmly in place. The upper surface of this plate 3 is provided with a plurality of teeth 5, which are arranged to engage the teeth on the cooperating plate and lock said plate against lateral movement. Formed near one end of the plate 3 is the rectangular aperture 6, and near the other end is the circular aperture 7 which are arranged to receive the spike 8 and screw spike 9 respectively.

Specification of Letters Patent.

Patented Mar. 30, 1915. Serial No. 865,927.

Cooperating with the plate 2 designated generally by the numeral 10, which comprises the body 11 having formed thereon the teeth 12, which teeth are an ranged to engage between the teeth 5 and hold the upper plate 10 against relative movement. A rail flange-engaging member 13 is formed on the upper face of the plate 10, and this rail flange-engaging member is arranged to engage the rail flange 14 formed on the rail, designated generally by the numeral 15. Formed near the lateral extremities of the body 11 are the transversely extending slots 16 and 17 which are arranged to receive the spike 8 and bolt 9 respectively when the device is in use. Extending downwardly from the lateral extremities of the upper plate are the longitudinal flanges 18, which are arranged to hold the body 11 spaced from the body 3 as clearly shown in the drawings.

It will be apparent from the foregoing that in use the plate 2 is first laid on the rail at the desired point and driven in place by forcing the rib 4 into the tie. The top plate 10 is then placed over the upper plate so that the teeth 12 engage the teeth 5 and prevent lateral movement of the upper plate with relation to the lower plate. The rail is then slipped in place so that the flange 14 will engage beneath the flange-engaging member 13 and the spike 8 is then driven in place though not tightly and a slight space is left between the head of the spike and the upper surface of the rail flange. The screw spike 9 is then struck and the rail moved inwardly or outwardly until the proper gage is reached, whereupon the spike is driven firmly against the rail flange and the bolt turned down so that it firmly locks the upper plate 10 against the plate 2. It is to be understood that a suitable locking washer 19 may be employed if so desired to prevent the screw spike 9 from becoming accidentally turned and thereby further insuring the rails against movement.

From the foregoing it will'be apparent that a particularly simple and effective tie plate is provided which may be easily and quickly set in position and will also eficiently hold the railroad rails from lateral movement, thereby insuring the proper gage of the rails at all times and preventing any derailment of the rolling stock passing thereover.

While in the foregoing there has been is the plate shown and described the preferred embodiment of this invention, it is to be understood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the invention as defined in the appended claim.

What is claimed is: a

A railroad tie plate including a base plate, a rib extending transversely of the base plate, said rib being arranged to extend into a tie to hold the plates in place, teeth formed on the base plate, a top plate, teeth formed on the top plate, the teeth on both plates being arranged to engage each other to hold the plates against relative movement, longitudinal ribs extending across the sides of the top plate and holding said plate in spaced relation to the bottom plate, the bottom Qopie: at this patent may he obtained for plate being provided with a spike-receiving aperture and a bolt-receiving aperture, the top plate being provided with transversely extending slots,

ber carried by the top plate and arranged to hold a railroad rail thereon, a spike arranged to pass through one of the slots and through the spike-receiving aperture, and a bolt arranged to pass through the opposite slot and the bolt-receiving aperture, and means to lock the bolt against accidental rotation.
