FREDRIC C. WEIR, OF CINCINNATI, OHIO.

RAILROAD-SWITC H.

SPECIFICATION forming part of Letters Patent No. 273,785, dated March 13, 1883,

Application filed December 22, 1882. (No model.)

To alt whom it may concern Be it known that I, FREDRIC C. WEIR, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State ot' Ohio, have invented certain new and useful Improvements in Railroad-Switches, of which the following is a specitication.

My invention relates to improvements in railway-switches, and is designed particularly as an improvement on the switch shown and described in Letters Patent of the United States No. 241,260, granted me May 10, 1581.

It has been customary heretofore in order to have the respect-ive outer Ilanges ot' the movable or tongue rails of a railway-switch tit and rest upon the respective inner anges ofthe stationary or main rails to cut or plane away the bottom ot' the said tongue-rails,which greatly weakens that portion thereof, rendering them defective, and necessitates the use ot' Jfriction-plates of unequal thickness.

To overcome this defect is the object of my invention, which consists in upsetting the flanges and web ot' the tongue-railsin suitable dies in such a manner that the said iianges will tit and rest snugly and firmly upon the iianges of the stationary or main rails, and also have a solid bearing in the usual manner on the friction-plates upon which both main and tongue rails` are set and the same level maintained, thereby avoiding the employment ot' friction-plates of unequal thickness.

In the accompanying drawings, Figure l is a plan View of a railway-switch embodying my invention.A Fig. 2 is au enlarged transverse section on line .r w, Fig. l, showing the manner in which the flanges ot' the movable rails are upset. Fig. 3 is a broken transverse section on line y y, Fig. l. Fig. 4 is a transverse section taken at the point of the tonguerails on line e z, Fig. l; and Fig. 5 is an enlarged bottom plan view, showing the upset portion of one ofthe tongue-rails. y

A A represent the cross-ties, upon which are set the stationary rails B B and movable or tongue rails C C'.

D represents the customary friction-plates, upon which the movable rails C C slide for adjustment.

E are the spacing bars or rods for counect- 5o ing the said movable or tongue rails to move in unison.

F represents brace-blocks resting against the outer faces of the stationary rails B B', and secured in position on the outward eXtensions of plates D.

The webs c and anges of the tongue-rails C C adjoining the inner tlanges of the stationary rails are by means ot' suitable dies shaped and upset 'from the point at which the 6o stationary rails cross the path of the movable rails to the point ends of said movable rails. The heads c ot' the tongue-rails are cut away but a short distance from their points, suijcient to accommodate the relative angles of the tongue and stationary rails. The full strength ot' the flanges ot' the tonguerails is preserved throughout their length, as the metal is not eut away in any manner where the movable and stationary rails come in con- 7o tact, but is shaped and upset in dies, as aforesaid, so that a part ofthe rail tirmly rests on the platesDand the turned-up portion G rests on the lianges ofthe fixed rails.

It will be seen that the movable and stationary rails are on the same level, both being set on the friction-plates D and the web of the tongue-rails contracted in height by being upset together with the flanges at the turnedup portion thereof.

I claim- In a railway tongue-switch, the combination, with the stationary rails, of the movable rails resting and sliding in the same plane as the plane in which the stationary rails rest, and having their respective outer flanges swaged and shaped to t and rest upon the tlanges of the stationary rails, whereby the cutting and planing awayot' the said movable rails is obviated, substantially as described, 9o for the purpose specified.

In testimony whereofI have hereunto set my hand in the presence of two subscribing witnesses.

FREDRIC C. WEIR.
