RAILWAY TIME-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 45,981, dated December 2, 1890.

Application filed Apn'llS, 1890- Serial No. 348,486. (No model.) i

To all whono it may concern.-

Be it known that I, WILLIAM H. SAYLEs, a citizen of the United States of America, residing at Corning, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Railway-Signals, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements in railway-signals or time-indicators; and it has for its object the production of a new and improved device of this class, whereby the time of passage of a train is indicated within a certain limit to the next following train, and which is self-winding when operated and entirely automatic in its movement.

The invention comprises a signal having a minute hand of limited movement, clock mechanism imparting motion to said minutehand, means for automatically stopping and restarting said clock mechanism, and a depressible bar which is held continuously lowered during the passage of a train at the point where located, and means for automatically rewinding said clock mechanism; and the mvention further comprises detail novel consignal applied to the side of a track.

structions, combinations, and arrangements, substantially as set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective showing my improved Fig. 2 is an end elevation showing the operatingbar and its connection to a rail. Fig. 3 is a side view of said connection. Fig. 4 is a vertical sectional view on the line as at, Fig. 1, showing the operating-lever and its cable. Fig. 5 is a side View thereof, taken on a section through the inclosing-box of said lever. Fig. 6 is a front elevation showing my improved signal. Fig. 7 is a similar but enlarged view with one side of the inclosingcasing removed and a portion of the dial broken away. Fig. 8 is a vertical sectional view on the line "y 3 Fig. 7, taken through the clutch-connection of the minute-wheel shaft or arbor. Fig. 9 is a View in perspective of the levers and their connections for rewinding the clock mechanism. Fig. 10 is a vertical sectional view taken on the line a .2, Fig.

'7. Fig. 11 is a view in perspective ofthe minute'hand and its operating-shaft and adjuncts. Fig. 12 is a central longitudinal sectional view of said shaft, the clutch, and the means for operating the same. Fig. 13 is a view in perspective of the balance-wheel starting and stopping device.

Referring to the drawings, A designates the signal proper; a, a post, preferably metallie, having a lower portion a secured in the ground adjacent a track, and a a door or removable port-ion in the lower part of said post. Within the semicircular case a of signal'A is a double-f ace dial B, centrally located therein.

0 is a minute or index hand having an outer doublepointed or bifurcated end formed by two parallel pointers I) I), designed to move over both faces of the dial, so as to serve as an indicator visible from opposite directions. The other end of this hand has a light counterbalance-weight b.

D is a shaft, upon which hand 0 is rigidly mounted, the ends of said shaft being secured so as to revolve in the outer ends of two parallel arms cl cl, rigidly attached to opposite walls of a box or casing 61. To a collar (1 of shaft D is connected one end of a coil-spring (1, the other end thereof being connected to one of the arms (Z or some other suitable point. This spring serves to return hand 0 to its starting-point when the clock mecham ism is thrown out of gear.

E is a shaft supported at its forward end by an arm 6, secured to one of the arms d, and it is provided with a bevel-pinion c, which gears with asimilar pinion 6 fast upon shaft D. To the rear end of this shaft E is secured a ring or hollow collar 6, wherein fits a clutch 6 This clutch consists of a ring or disk a having a collar e secured fast upon the shaft or arbor e" of the minute-wheel, and a series of short rods or teeth a loosely disposed in holes or apertures of said ring or disk and capable of being forced outward and engaging ring or collar 6 by means of the tapered or cone-shaped end 6 of a movable sleeve c. This sleeve c is placed upon shaft or arbor 6 and its other end has a collar e", against which bears a coil-spring e, which encircles shaft or arbor e and bears at its other end against. a collar 2 thereon.

F is an arm having a lower U-shaped portion f, which expands sleeve 6 and thelower ends of the arms f of said U-shaped portion are pivotally secured to the outer ends of a bracket f made fast to the frame of the clock mechanism X. To the upper end of this arm F is secured a roller or wheel f with which engages a plate or thickened portion f on a vertical operating-rod G when said latter rod is drawn downward, causing the rearward movement of arm F and sleeve e and consequently the withdrawal of the cone-shaped end of said sleeve from the clutch, thus effecting the loosening of the bite or engagement of the rods or teeth e against ring 6 This stops the revolution of shaft E, and the spring at will return the hand 0 to its starting-point.

H designates the device for automatically stopping and restarting the movement of the balance-wheel h at and during the passage of a train. A vertically-disposed frame h is secured to the frame of the clock mechanism, and through an upper aperture thereof is passed a rod if, having a transverse arm 71 against which bears the upper end of a coilspring 71 the lower end thereof bearing against a crossplate 715 of frame 7i. This rod h2 is guided in its movement by a short red 7t, secured thereto and extended through an elongated slot in the top of frame h. To one end of arm ha is secured the upper end of an arm h of a clutch or foot h which when lowered bears tightly against the balancewheel h and holds the same from turning, an d when released imparts an initial movement to said wheel. To the other end of arm 72. is connected an arm 7Z8, having a lower right-angular end, with which is designed to engage the end of an arm 71*, rigidly secured to rod G.

I is a' lever fulcrumed att' between short arms of plate 7r. The upper end 1" of this lever is weighted and its lower end i is forked. hen spring-held rod 71- is lowered by arm 71", hearing on arm 77. lever I tilts forward at its upper end, and when said rod reaches the limit of its movement the forked end of said lever will engage a cross-pin i". of said rod and hold the same in its lowered position until the upper end of lever I is moved rearward by the engagement therewith of arm 71,9 in the upward movement of rod G, at which time the rod 7L2 being released will fly up ward and the clutch or foot will impart an initial movement to the balance-wheel and start the working of the clock.

I will now describe the means by which the clock is automatically rewound at each operation of the signal.

1 J designate the two mainsprings; j j, ratchet-wheels adjacent the ordinary gearwheelsj', and j small spring-pressed pawls engaging said ratchet-wheels. The shafts or arborj of these mainsprings(to which said ratchet-wheels are secured) are extended and supported eachby a bracket or arm 9' To the outer ends of these shafts or arbors are keyed the upper ends of arms or levers K, the lower ends of which are provided with short studs 70, proj ectin g on either side and extended into opposite slots or openings of two parallel bars 7& These bars 7& are secured together and extend on either side of rod G and have a roller 70 secured therein, with which is designed to engage a tapered block or plate 10* (or it may be an enlargement) of said rod G.

The movement of the clock will cause the arms or lever K to move parallel with each other in the direction of the arrow to, and such movement thereof will continue until the index-hand (which is connected to the clock mechanism through the agency of the shafts D and E) shall have traversed the face of the dial and come in contact with the pin at the bottom of dial, such contact causing the clock mechanism to come to a standstill. As the clock mechanism is thus brought to a stop, the arm K adjacent plate 70 of rod G is up against said plate, the roller 70 being then-at the lower inner end of the tapering portion thereof. The parts so remain until the bar Gis lowered, when its plate R will press against the roller k and through the agency of connecting-bars A return arms or levers K to their original position, and thus effect the winding of the springs by the turning of the shafts or arbors thereof, to which said arms or levers are secured. From the foregoing it will be seen that as the rod G is lowered three results are simultaneously secured: first, the stopping of the movement of the clock mechanism; second, the return of the indicating-hand to the starting-point,and, third, the rewinding of the clock-springs. In the elevation or return movement of said rod the clock mechanism is again started by the initial movement imparted to the balancewheel.

Vhile it is obvious that various means mav be employed for operating the signal hereinbefore described, yet that specially designed therefor will now be specifically set forth.

The operating-rod G is extended down through port a, and may, as shown in Fig. 6, have a coil-spring g encircling its lower end and held by a collar g and a partition or apertured cross-piece g or said spring-pressure may be applied to the upper end of said rod, as shownin Fig. 7, wherein a coil-spring g encircling said rod, is disposed in a hollow tube or cylinder 9 connected to the top or roof of box or casing d. To the lower end of rod G is connected by a turn-buckle 9 one end of a rope or cable L, which, after being passed around a pulley Z, hung in post a, is extended through a pipe Z beneath the rails of a track V, and connected to the lower free end of a lever M. This lever is secured upon apivotal rod m, which is preferably made in two or three parts or sections of equal length, the conjoint length of said sections being about forty feet, (the distance between the wheel-trucks of a passenger-car.) This rod is supported throughout its length, so as to be free to turn, byaseries of supporting arms or bearings N. Each arm or hearing comprises two parts or members it 12., having hooked portions niwhich hug opposite points of the lower flange of a rail, and-are firmly bound thereon by a nutted bolt 71', which holds together the lower flanged ends 72 of said parts it it. To the bar at between the upper forked ends of the part H of each bearing is rigidly secured the circular portion of an arm a having an outer flange n.

O is a long continuous bar secured through out its length to the flanged ends of arms w". This bar occupies an inclined position parallel with and adjacent to the tread of the adjoining rail, above which it projects a short distance sufficient to be engaged and depressed by the slight projecting portion of the periphery of a car-wheel. This bar is held continuously depressed during the passage of a train.

The inner opposite ends of the sections of rod m are projected into a box or casing P, which is secured to the flange of a rail in a manner similar to the arms or bearings N. To the inner end of one section of this bar lever M is rigidly connected, and on either side of said lever are two arms 19 p, the former being connected to the end of the other section of the bar. The lower ends of these arms work in the slotted ends of a bar or crosshead f, rigidly secured to lever M, whereby the movement of one section of rod m permits a similar motion of the other section by reason of the movement of lever M and crosshead 19 In the front wall of box or casing P is screwed a bolt Q, held at the proper adjustment by a check-nut q. The inner end of this bolt is on a line with the lever M, and

the extent of the movement of the latter is controlled by the adjustment thereof. By means of this adjustable bolt the position of the depressible bar 0 with relation to the tread of the rail can be adjusted, and hence a greater or lesser movement can be imparted .to the operating-rod G, according as the adjustment of the parts may require.

In practice the clock mechanism will be set in motion at the passage of a train with the indicating-hand at one (1) or the startingpoint, the same being indicated on both sides of the dials by the double-pointed ends of said hand. Should the next following train pass the point where the signal is located before the hand reaches the limit of its movement, (thirty minutes being preferably elected) the elapsed time since the passage of the previous train will be indicated. Immediately upon contact of the wheel of the engine or front car with the depressible bar 0 the latter will be lowered, and through the agency of rod on, lever M, and cable L will instantly effect the lowering of or a downward pull on operating-rod G. The initial movement of this rod will eifect the disengagement of the clutch between the minute-wheel shaft or arbor and shaft E and permit the indicatinghand 0 to return to its starting-point at the top of the dial. The further or complete movement of rod G will cause the rewinding of the mainsprings of the clock and at the same time the clutch or foot 71 will bind the balance wheel as against movem ent, thus completely stopping the working of the clock. By making the bar 0 of the length stated the same is held depressed until the rear truck of the last car has passed thereover, immediately upon which the rod G will be elevated by the action of the spring, and the restarting device being freed by the arm h of rod G the clutch or foot thereof will turn the balance-wheel and set the clock mechanism in motion. At the same time the cone-shaped end of the spring-pressed sleeve will be moved forward and the cl u tch-connection established with the shaft E, and thus again starting the indicating-hand on its movement. By reason of the double-face dial the engineer of a passing train is enabled to observe from the opposite side whether or not the signal has been operated and reset.

I am aware that it is not new to employ a double dial for a railway-signal; but I am not aware of any such device having one hand serving as an indicator for both dials.
