Application filed December 22, 1921.

it may concern:

To aZZ whom- Be it known that 1, JOHN HARRISON, a citizen of the United States, residing at in the county of Cochise and State of and use ful Improvements in Tie Plates; and T 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 a railway appliance and more particularly to means for securing the rails to the ties to prevent creeping or other movement which is ob jectionable and detrimental to rolling stock.

The invention provides a tie plate and rail lock whereby the rail is held securely against movement in either direction and all tendency of loosening is prevented by the passing of rolling stock thereover.

The invention furthermore aims to eliminate all noise and rattle caused by any slack between the rail flanges and tie plate shoulder, such parts being constructed to have a close fit and obviate any possible play with the result that all noise and rattle are practically eliminated.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the application,

Figure l is a top plan view of a tie plate and rail lock illustrative of the invention,

Figure 2 is a section on the line 2-2 of Figure 1,

Figure 3 is a detail view of the tie plate in perspective, and

Figure 4c is a detail perspective view of the key.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The tie plate 1, as shown, is of rectangular form and is provided adjacent opposite edges with shoulders 2 and forming se- Naco,

Serial No. 52%,200,

the rail 4: in po- Xtends the full length of the plate 1 and its inner wall is curing means for retaining sition. The shoulder 2 undercut, as indicated at 5, to receive the flange of the rail 4L. The shoulders 2 and 3 are disposed inwardly from the edges of the plate 1, whereby to leave marginal poi tions in which are formed openings 6 for receiving the spike or ether fastening means whereby the plate is made secure to the tie. The shoulder 3 terminates a short distance from one end of the plate 1 whereby to provide clearance for receiving an ear 7 projecting laterally from the driving end or a key 8 which cooperates with the shoulder 3 to secure the rail l to the plate 1 by means of a wedging action. A longitudinal channel 9 is formed in the upper side of the plate 1 adjacent the shoulder 3 and receives the lower portion of the key 8. The inner wall of the shoulder is provided with a groove/ 1O which is adapted to receive a rib 11 at the outer side of the key 8. The in ner wall of the key 8 is formed with a groove 12 to receive the flange of the rail The shoulder 3 is longitudinally inclined, whereby to cooperate with the key 8 to insure a wedging action in the securing of the rail 4: to the plate. The corner portion of the plate 1, in line with the shoulder 3, is cut away, as indicated at 13, to the plane of the channel 9 to receive the ear 7 which, when in position, forms a continuation of the shoulder 8. An opening 14L is formed in the ear 7 to register with an elonated opening 6 formed in the part [3 of the plate, whereby the spike or ether tening passing through the registering openings 14 and (3 serves both to secure the key 8 and the plate 1 to the tie.

The wedge or key S is of such width as not normally to be fully in the position shown in Figure 1, whereby provision is had for driving the key to secure the rail by a wedging action.

A tie plate and rail lock constructed substantially as herein set forth firmly secures the rail and prevents any relative play or movement thereof and obviates noise and rattle which are disagreeable and detrimental to rolling stock.

JV hat is claimed is:

A tie plate having opposed cooperating shoulders, one of the shoulders extending the full length of the tie plate and having its inner wall undercut, and the other shoula rib at its outer side to fit the groovev of the short shoulder, and having a lateral ear 10 at the driving end to-fit the cut away portion of the plate, said ear having an opening to register With a corresponding elongated opening in the cut away portion of the plate.

In testimony whereof I afiix my signature 15 in presence of two Witnesses.
