To all whom it may concern: of securing the pivot pin to the tongue, Fig. Y Be it known that I, HENRY OSHEA, a citi- 9 showing the pin pivoted in the tongue while zen of the United States, residing at Johns- Fig. 10 shows the tongue and pin integral. town, county of Cambria, State of Pennsyl- These last two iigures also illustrate different 5 Vania, have invented a new and useful Imforms of recess R. 55

To said tongue is secured at one end the pin 1o My invention relates to that form of switch p upon which it turns, the boss B furnishing 6o which has a movable tongue or point hinged abearng for it. The end of the tongue is upon a pin near one end. In switches of this here shown having a fiat end but of course character the dirt about the tongue has a Vany other suitable shape may be substituted tendency to accumulate at the point'of least therefor. The end of the tongue has formed 15 motion which is near the pin and at this in it the recess shown at R Figs/tand 7into 65 point to gradually lift the tongue.

This plate time without taking the switch up from the does not extend entirely across that portion track or disturbing the paving or road bed of the switch frame directly behind the 35 and is speciallyadapted to that typeof switch tongue and lying between the two track 85 in which the tongue is rigidly secured to the grooves.

By 9o bodying my invention. Fig. 2 is a top view track surface I mean a surface performing of the head end of the Sallie. Fig. 3 is a secthe same function as the head of the rail, that tion on line o o. and Fig. 4 is a section on is, a surface which supports the tread of the line b-b. Fig. 5 is a top view of a switch wheel as it rolls along the track. Were the 45 similar to Fig. 2 but having different style plate O to lie here so that the wheel traveled 95 of plate C. Fig. 6 is an end view of the switch over it, the action of the wheel would tend to from the line c-c. Fig. 7 is a vertical secloosen and wear and so greatly destroy the tion on line b-b. Fig. S'shows a section on efficiency of the plate. I therefore construct line a-a of a switch composed of rolled steel the plate so that it only occupies a portion 5o rails R R. Figs.9and 10 illustrate methods of the place behind the tongue, and I form 1o.b

2' sedoi the track surface upon the body of the switch. The wheel thus travels only upon the tongue and the main body of the switch.

The method of applying this device is as 5 follows: The tongue T having been placed in position and the nut N being in its pocket the plate C is put in place with the lug Z entering the recess R in the tongue, the bolt d is inserted in nut N and the whole clamped 1o together. Instead of the lug Z entering a recess as shown in Fig. 4, the metal of the tongue shown above the recess might be removed and the full thickness of the plate C extended over the portion of the tongue eX- tending beneath the plate, Fig. 7, or it might be otherwise constructed, the essential feature being to have a portion of the plate C extend over a portion of tongue T so that it shall exert a clamping down action thereon. 2o While the drawings show the switch piece made in one integral piece it will be seen that it might be constructed of rails of rolled steel cut and fitted together without departing from my invention. Fig. 8 shows such 2 5 construction, R', R being the rolled rails and F a cast metal chock or filler having the boss B for the tongue pin and adapted to support the plate C. The rails R R are riveted or similarly secured to this chock F as shown.

I-Iaving thus fully described my invention, what I claim, and desire to protect by Letters Patent, is-

1. In a railway tongue switch in combina tion with the main frame of theswitch,apiv oted tongue havingatrack surface thereupon adapted to support the car wheel; a track surface formed on the frame of the switch and abutting the pivoted end of the tongue and forming a continuation of the surface 4o thereupon, and a holding-downplate engaging the pivoted end of the tongue and lying in a pocket adjacent to the aforesaid track surface upon the switch frame, said plate being secured to the frame of the switch.

2. In a railway tongue switch, a switch frame having a pocket; a tongue pivoted in said pocket, said tongue having upon it a track surface; a track surface formed upon the switch frame, abutting and forming a continuation of that upon the tongue so that 5o a car wheel may pass directly from one to the other, and a plate adapted to engage and hold down the pivoted end of the tongue, said plate being secured to the frame of the switch.

3. In a railway tongue switch, in combination with the frame of the switch, a tongue pivoted therein; a holding-down plate overlapping the pivoted end of the tongue; a socket in the frame; a nut in the socket, and a bolt passing through the holding-down plate, engaging the nut and adapted to secure the plate in place.

4. In a railway tongue switch, in combination with the frame of the switch, a tongue pivoted in said frame; a track surface upon the tongue throughout its length; arecess in the pivoted end adjacent to, but not extending into the track surface; a continuation of said track surface on the frame of the switch and abutting the tongue, and a plate enter- 7o ing the recess in the tongue and lying adjacent to the track surface on the frame, said plate being secured to the frame by a bolty passing through the plate and the frame.

In testimony whereof I have affixed my signature in presence of two witnesses.

HENRY OSIIEA.
