DERAILING-S WIT CH.

SPEGIFICATIIEON forming part of Letters Patent No. 534,520, dated February 19, 1 895. Application filed December '7, 1893. Serial No. 493,041. (No model.)

To all whom zit-may concern:

Be it known that I, EDWARD SAMUEL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvementsin Derailing-Switches, of which the following is a specification.

My invention consists of certain improvements in thederailing switch for which Letters Patent were granted to William Wharton, J12, on the 12th day of September 1893, No. 505,076. 1

The object of the present invention is to so construct the operating mechanism of the switch that the tongue of the switch cannot be moved excepting fromthe operating box, the mechanism shown effectually locking the switch excepting when operated at the point where the operating box is located.

Another object of the invention is such an arrangement of the parts as to keep dirt from falling into the box in which the partswork and surround the operating rod in such a way that it cannot be affected, by frost or dirt.

A third object is to make the operating box in such a method as will prevent its being tampered with by the public.

These objects Iattain in the followingvmanner, reference being had to the accompanying I drawings, in which Figure l, isa plan view illustrating my improved derailing switch at a crossing. Fig. 2, is a plan View ofv .the switch on a larger scale. Fig. 3, is a plan view .with the top plate removed and the rail in section. Fig. 4 is a vertical sectional view on the line 4-4, Fig. 2. Fig. 5, is a perspective view of a detail of the mechanism. Fig. 6, is a plan view of the operating box. Fig. 7, is a plan view of the box with the cover removed. Fig. 8, is avertical sectional view of the box on the line 8-8, Fig. 6. Fig. 9, is a transverse section of the operating boxon the line 9-9, Fig. 6. Fig. 10, is a perspective view of a detail; and Fig. l1,is an enlarged sectional view .of one end of the protecting tube for the connecting rod.

As fully set forth in the above mentioned patent the object of a derailing switch is to derail a car if the attempt is made to propel past points where the switch is located without the conductor preceding the car and turning the switch mechanism so that the switch will be moved clear of the rail, the invention being especially applicable ,for use onstreet railway tracks which cross steam roads, draw bridges and other dangerous points.

By keeping the switch normally set so that it will derail a car all danger that would be caused by negligence is avoided as the conductor or switchman must precede the car and move the switch; otherwise the car will be derailed. 1

AA are the tracks of the street railway, B B in the present instance representing the tracks of a steam railroad crossing the same. Some distance from the junction is placed the derailing'switch structure D having the switch tongue-d which normally rests upon one of the rails A and is so formed that it will guide the wheels of a car off the track and derail them, the distance between this switch structure I) and the crossing being sufficient to enable the car to come to a stand still if derailed, before reaching the track B.

E is the operating box, in the present instance situated between the rails B B of the steam railroad track, and the operating mechanism in this box is connected to the switch mechanism by a rodf. By arranging the operating box between the rails B B, it will be impossible for the conductor or switchman to move the switch when a locomotive or car is traversing the tracks B B, but it will be understood that the operating box can be placed at any point near the crossing, so that the operator can clearly see whether or not the tracks are clear.

j Referring to Figs. 2, 3 and 4, it will be noted that the switch mechanism is inclosed in a casing D having a suitable cover plate D The switch tongue 01 is pivoted at d and extending from the switch tongue is a plate d having a pin (1 which is adapted to a cam groove 0 in a drum 0 pivoted to suitable bearings in the: casing D, the pitch of this cam groove being such that the switch tongue cannot be moved except through the medium of the drum. The drum is connected to a slide G by a rod c, the slide being connected in turn to the operating mechanism in the box E by the rod f, as described hereinafter.-

Depending from the drum 0 is a pivoted weight 0 having detachable sections 0 this weight serving to return the switch tongue to its normal derailing position as soon as the drum is released by the operator.

The slideGis adapted to suitable ways 71. h on the casing D and has a slotted extension g, clearly shown in Fig. 5, and the rod f passes through the slotted extension and has confining nuts on each side so that it can be vertically adjusted.

The slide I in the operating box E also has a slotted extension i through which the opposite end of the connecting rod fpasses and the rod is also provided with confining nuts at this end. Hence it will be seen that the rods can be adjusted vertically so as to accommodate different track constructions.

The operating rodf passes through a pipe F which rests upon the ties of the track structure and this pipe is provided with stuffing boxesf' at each end through which the 'rod passes, the pipe being filled in any suitable manner with lubricating material, preferably oil, which not only'lubricates the connecting rod but also keeps the pipe free from dirt and the accumulation of moisture which would cause rust and in many instances freeze in cold weather.

The operating mechanism shown in Figs. 6, 7 and S is confined in the box E which is set in the ground, the upper edge being flush with the paving. The cover E rests within the box and in this cover is a circular opening 6 in which rests the operating disk lever E which is supported by a post 6' projecting from the bottom of the box. Apin 6 projects from the post into the operating disk and I preferably mount a washer between the post and disk.

The slide I is guided between a bracket on the box and the cover and has a slot 2" into which a pin 8 passes, the pin being secured to the under side of the operating disk E In the top of the operating disk E is an inclined opening 3' into which can be inserted an operating bar. By giving the operating disk a quarter turn in the direction of the arrow Fig. 6, the switch tongue d will be moved from the position shown in full lines in Fig. 2, to the position shown in dotted lines clear of the track, but as soon as the car passes the switch the operator can remove the bar and the weight C will return the switch tongue to its normal derailing position.

In some instances a sliding plate may be substituted for the drum, the plate having the inclined slot for the reception of the pin of the switch rail, or a spring may be substituted for the weight, but I prefer the construction shown in Fig. 4, of the drawings.

I claim as my invention- 1. The combination in a derailing switch, of the pivoted drum, an inclined slot therein, a switch rail, a pin depending from said switch rail and entering the slot in the drum, a weight suspended from said drum, operating mechanism situated some distance from the rail and connections between said operating mechanism and the drum, substantially as described.

2. The combination of a switch rail, shifter therefor, operating mechanism situated at some distance from the rail shifter, a vertically adjustable rod connected to the switch rail shifter and to the operating mechanism, with means for securing the rod in the adjusted position, substantially as described.

3. The combination in a derailing switch, of the switch rail, pin depending therefrom, a weighted pivoted drum, a cam slot in said drum into which the pin on the rail extends, a slide connected to said drum, switch operating mechanism situated some distance from the switch rail, vertically adjustable connecting rod connecting the operating mechanism with the slide, substantially as described.

4. The combination of a switch rail, the operating mechanism situated some distance therefrom, a connecting rod through which motion is imparted to the switch rail from the operating mechanism, a tube inclosing said rod, said tube being closed at each end and containing oil or other lubricating liquid, substantially as described.

5. The combination in a derailing switch, of the switch rail, the mechanism for throwing said switch rail, the operating lever situ' ated some distance from the switch rail, a slide G connected to the rail throwing mechanism and a slide I actuated by said operating lever, a connecting rod vertically adjustable in said slides G and I, substantially as described.

6. The combination in aswitch, of the switch rail, mechanism for throwing the switch, an operating lever in the form of a disk, flush opening in which an operating bar can be inserted and a connecting rod connecting the switch operating mechanism with the switch throwing mechanism, substantially as described.

7. The combination of the switch structure D mounted in an inclosing box and consisting essentially of the pivoted slotted drum, a weight therefor, a slide adapted to ways in the inclosing box, and a connecting rod connecting the slide to the drum,a pivoted switch rail having a pin entering the cam slot in the drum and the operating mechanism inclosed within a box and consisting of a disk lever flush with the surface of the street, a slide with which said lever engages, with a vertically adjustable rod connecting the switch operating mechanism with the switch mechanism and a tube inclosing said rod, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD SAMUEL.
