WEAR-PLATE FOR RAILWAY-SWITCHES..

Specication of Letters Patent.

Application led December 23, 1905. Serial No. 293,097.

To all whom it may concern:

Be it known that we, WILLIAM H. ELLIOT, residing in St. Louis, in the State of Missouri, and JOHN J. TowNsEND, residing in East St. Louis, in the State of Illinois, citizens of the United States, have invented certain new and useful Improvements in Wear-Plates for Railway-Switches, of which the following is a full, clear, and eXact description, reference being had to the accom anying drawings, forming part of this speci cation.

Our invention relates to an improvement in that class of wear-plates on which railwayswitch-point sections rest for sliding movement and which are of pressed description, being struck from a single piece of metal. In wear-plates of the kind named it is common to press from the plate an upwardly-extending projection on which the switch-point railsections ride and which serve to provide shoulders against which one of the bottom flanges of the adjacent main-track rail rests to be held against lateral movement. As the wear-plates of pressed form have heretofore been made there have been present in them weakened points, due to the upsetting of the metal at the locations of their projections,

which have rendered the plates extremely7 susceptible to breakage at such' weakened points, as a consequence ofwhich the plates are unreliable and unsafe for their utility, as

mentioned.

It is the object of our invention to provide against ,breakage of the wear-plates at their weakened points, and to attain this object we reinforce the plates at their struck-up portions, or, in other words, at the location of the upwardly-extending projections.

Figure I is a top or plan view of parts of a railway-tie, a main-track rail, a switch-point rail-section, a switch-rod connected to said section, and our wear-plate in a position in which it may be used to receive said switchpoint rail-section. Fig. II is an enlarged top or plan view of one of our wear-plates. Fig. III is a cross-section taken on line III III, Fig. II. Fig. IV is a longitudinaI section taken on line IV IV, Fig. II, with a main rail Fig. V is a top or plan view of a modification of the wearplate. Fig. VI is a cross-section taken on line VI VI, Fig. V. Fig. VII is a longitudinal section taken partially through another modification of our wear-plate.

A designates a railway-tie, and B a maintrack rail supported by said tie.

C is a Aswitch-point rail-section that is adapted to be connected to a mating switchpoint rail-section bya switch-rod D.

I designates a pressed wear-plate that is mounted upon the tie A and secured thereto by any suitable means, such as spikes. This wear-plate is provided with an upwardlyextending projection 2, which is struck or pressed from the body of the plate and on which the switch point railsection C is adapted to ride. In pressing the projection 2 from the body of the plate said plate is weakened at the sides and ends of the proj ection, and particularly at the innermost end 3 of the projection against which it is usual to seat the main-track rail B, so that it will rest against a shoulder produced at this point, as seen in Fig. IV, to hold the main rail against lateral movement in a direction toward the projection. To compensate for the weakening of the body of the plate at the ends and sides of its projection, we locate in the recess beneath said projection a reinforcing-plate 4, that is preferably of such thickness that its lower side will occupy a plane corresponding to the plane of the wear-plate at its lower side and will rest upon the tie beneath the plate, thereby relieving the projection 2 of the plate of strain to which it would in the .absence of the reinforcing-plate be subjected.

The projection 2 is preferably located entirely within the sides and ends of the wear-plate, as shown in Figs. I to IV, inclusive, and it also preferably has its greatest length in a direction longitudinal of the wear-plate. For the purpose of providing for the retention of the reinforcing-plate 4 in its seat beneath the projection 2 said reinforcing-plate is preferably beveled at its ends, as seen at 5, Fig. IV, and the reinforcing-plates are set into said seats while the metal of the wear-plate is in a heated condition, and by pressing the parts together with the wear-plate in such heated condition the reinforcing-plates'are caused to become embedded at their tapering ends with an angular joint into the bodies of the wear- IOO plates and will thereafter retain their positions without` the necessity of utilizing any member to hold them in position.

In Figs. V and VI we have shown modifications of our wear-plate, in which the parts differ from those described in that the Wear plate 1L has its projection 2fL extending transversely across the 'plate from side to side thereof instead of being located entirely within the sides and ends of the plate and in which the reinforcing-plate 4 extends transversely across the wear-plate beneath said projection instead of longitudinally of the wear-plate. In Fig. VII we have shown another modification in which the reinforcingplate 4b is connected to the wear-plate at the ocation of its projection 2b by rivets 6 instead of being secured to said wear-plate in the manner previously described.

We claim as our invention- 1. As a new article of manufacture, a pressed wear-plate of the character described having a projection, and a reinforcing-plate set into said wear-plate at the location of said projection, substantially as set forth.

2. As a new article of manufacture, a pressed wear-plate of the character described having a projection at its upper side, and a seat beneath said projection, and a reinforcing-plate secured to said seat, substantially as set forth. l

3. As a new article of manufacture, a pressed wear-plate of the character described having a projection at its upper side and a seat beneath said projection, and a reinforcing-plate having angle-joint engagement with said wear-plate within said seat, substantially as set forth.
