SAMUEL L. FOSTER, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO THE MARKET STREET RAILWAY COMPANY, OF SAME PLACE.
ELECTRICAL BLOCK-SIGNAL SYSTEM.
SPECIFICATION forming part of Letters Patent No. 683,172, dated September 24, 1901.
Application filed October 161 1900- Serial No. 33 201. (No model.)
To all whom it may concern.-
Be it known that I, SAMUEL L. FOSTER, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Electrical Signals and I do hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to electrically-operated signals.
It consists in the novel means for operating the targets, as I shall fully describe.
The object of my invention is to provide a simple and effective electrical signal.
Referring to the accompanying drawings, Figure 1 is a front View of the interior parts of box A, showing an edge view of the target D. Fig. 2 is a top view of same. Fig. 3 is a cross-section through the sleeve E.
A is a box containing a pair of solenoids B, the cores of which are or form part of a rod C, which projects outwardly through one end of the box and carries the target D. Be: tween the solenoids is a sleeve E, in the walls of which are made the spiral or cam grooves e. The core-rod C is fitted with a cross-stud c, which travels in the cam-grooves e of the sleeve E and causes the core-rod when said rod is moved longitudinally to turn on its axis through a quarterrevolution, thereby throwing the target to either a vertical or a horizontal position, according to the direction in which said rod is moved. The circuitwires WV W lead in through insulators one to each solenoid and into the groundwires W W is let an ordinary safety fuse= box, (represented by F.)
The operation of the signal may be briefly stated as follows: When either of thesolen o ids is energized, the core-rod will travel to d the right or left, as the case may be, carrying with it'the cross-stud c, and as the latter travels in the cam-grooves 6 said rod will be caused to turn a quartenrevolution in one or the other direction, whereby the target D, carried by the end of the rod, will be correspondingly operated.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In an electrical signal, a pair of solenoids,
a core-rod common to both solenoids and adapted to be moved longitudinally in one direction by one solenoid and in the opposite direction by the other solenoid, a fixed sleeve 5 5 between said solenoids surrounding said corerod, and having a cam-slot, a projection on the core-rod engaging in said slot to cause the rotation of said core, when the latter is moved longitudinally by the solenoids, and a target operatively connected with said corerod and turned thereby, substantially as described.
In witness whereof I have hereunto set my hand.
