EDWARD SAMUEL, OF-PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE WILLIAM WHARTON, J R., & COMPANY, INCORPORATED, OF SAME PLACE.

DERAlLlNG-SWITCH AND SIGNAL.

SPECIFICATION forming part of Letters Patent No. 534,522, dated February 19, 1895. Application filed April 5, 1894. Serial No. 506.484. (I Io model.)

To whom it may concern:

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

The object of my invention is to so combine derailing switch mechanismwith signaling mechanism that on the operation of the dero railing switch the signal mechanism will be actuated and expose the danger signal on a crossing road, for instance when the derailing switch is thrown clear of the track. The construction of the mechanism is such that While the signals will be'thrown by the man who throws the switch'yet the signal mechanism is independent from the switch mechanism, so that the switch mechanism will not be affected should the signal apparatus get out of order.

In the accompanying drawings:-Figure 1, is a plan view showing the arrangement of my improved mechanism with a double track crossing. Fig. 2, is a diagram showing the derailing switches and signals in the position shown in Fig. 1. Fig. 3, is adiagram showing one of the derailing switchesmoved clear of the track and the signals. set to danger.. Fig. 4, is a plan view showing a single track 0 crossing a single track. Fig. 5, is a sectional view through the switch operating box, with the switch in the position shown in Fig. 2. Fig. 6, is a section through the switch operating box, with the switch in the position shown in 5 Fig. 3. Fig. 7, is a viewin elevation drawn to an enlarged scale of the signal stand.

Referring in the first instance to Figs. 1, 2, and 3, A A are the two tracks of a street railway and B B are the two tracks of a steam 4o railroad, crossing the tracks of the street road. as clearly shown in Fig. 1. The street cars traverse the street railway tracks in the direction indicated bythe arrows, Fig. 1.

D D are the derailing switches, which are 5 normally set at derailing position, so that a car traversing either track will have to be stopped before it reaches the derailing switch, and the conductor must precede the car and turn the disk 6 of the switch operating mech- 5o anism E so as to move the derailing switch clear of the track before the car can proceed.

The disk e in the present instance is con- ,nected toa slideF which is attached to a rod f extending to the derailing switch, so that on turning the disk for instance a quarter of a revolution the switch tongue at will be moved out of line with the track and as soon as the disk is released by the conductor after the car has passed the derailing switch, the switch tongue and the disk are returned to their normal positions by weights or springs.

The details of this switch mechanism are fully illustrated in the application filed by me December 8, 1893, Serial No. 493,041

In order to warn an approaching train, traversing either of the steam railroad tracks B B, I mount at suitable distances from the crossing, danger signals I I, one on each side of the crossing. The signal stands are constructed. as shown in Fig. 7. Mounted in the frame I is a vertical shaft '5 around which is v a coiled spring 71, one end of which is attached to the shaft and the other end attached to the'frame, the spring being so coiled that the signal will return to clear when re- 75 leased. A weight may be substituted for the spring in some instances. On the upper end of-the shaft are the blades and above the blades is the usual lamp. An arm 2' on the shaft of the signal Iis connected to an oper- 8o ating rod J and the arm 1' on the shaft of the signal I is connected to an operating rod J. The operating rods J, J are pivoted to bell crank levers K K, one on each side of the street railway track and extending from each 8 5 bell crank lever are rods 70 it. Each rod extends into a switch operating box and rests againstthe end of the slide F in the box, as clearly shown in Fig. 5. The rods 70 it are not attached to the slide but simply rest 0 against the slide, so that in the event of the signal mechanism getting out of order the switch mechanism will not be affected.

As shown in the diagram, Fig. 2, both derailing switches are set in derailing position 5 and the rods k, k press against the slides F, as shown in Fig. 5, by the action of the spring a" on the signal stands, but when the derailing switch D is moved clear of the track, as shown in the diagram Fig. 3, the rod 7c is too pushed in the direction of the arrow by the slide moving the signals to the danger position, as indicated in said figure; the rod 70' being simply drawn away from its slide F.

In Fig. 4, I have shown a single track crossing a single track and one derailing switch with two signals, one on each side of the street railway track and connected together by rods and levers and to a rod which extends into the switch operating box and which rests against the slide. a

One, two or more signals may be operated in the manner described above without departing from myinvention and the device may be used whereby two street railway tracks cross each other.

I claim as my invention- 1. The combination in a railway crossing, of the derailing switch, operating mechanism therefor situated some distance in advance of the switch, asignal or signals, a rod connected to the signal mechanism and resting against the switch operating mechanism sothat as the switch mechanism is operated it will push the rod and throw the signals, substantially as described.

2. The combination in a railway crossing, of the derailing switch, the operating disk, the slide connected to the disk and to the switch, a rod resting against the slide, a signal connected to the rod so that as the slide is operated to move the derailing switch it will push the rod and throw the signals, substantially as described.

3. The combination in a double track crossing, a derailing switch for each track, switch operating mechanism for each derailing switch situated at the crossing, danger signals on each side of the double track: connected together and to operating rods, said operating rods adapted to be operated upon by the switch operating mechanism, substantially as described.

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

EDWARD SAMUEL.
