H. B. RAYNEs i RAILROAD CROSSING SIGNAL vyl-i'lei March 10l 1924 Patented lil, i925 "aras RAILROAD-CROSSING SGNAL.

Application filed nai-011 1o, 1924. serial no. 698,164.

Be it known that l, HENRY il, Barnes, a citizenof the United States, residing at Buffalo, in the county ofJ Futnam andSta-te of lilest vlfirginia, have invented `certain new and useful. improvements in Railroad Crossing Signals, of which the following isv a specification.

This invention relates to railway signals and has special reference to crossing signals employing a flickering light for night signaling' and an oscillating semaphore blade for day signaling.

One important object of the invention is to improve the general construction of devices of this character.;

A' second important object of the invenY tion is to provide improved rail supporting means for actuating thesignal upon the passage of` trains.

A third important object of the invention is the provision of means specially adapted for ,actuating the signal upon the approach of va train onv a single track in either direction.l

llifith the above and other objects in view as will be'hereinaftr apparent, the inventioii coi. s ingeneral of certain novel dctails of construction and combination of parts hereinafter fully described, illustrated in lthe accompanying drawings and specifically claimed.`

In the accoiripanying drawings like characters of" reference indicate like parts in thesevreral views, and;

Figure 1 is a sideelevation partly broken away showing the sional and its actuating means in relation to a track rail.

Figure 2 is a detail perspective view of a certain rock shaft used in connection herewith.

Figure 3 is a detail section to an enlarged scale on the line 3-3 of Figure 1.

Figure et is a similar section on the line 4-4 of Figure 1.

Figure 5 is a detail view looking at one side of the semaphore from the direction ol' the arrows on the line 5 5 of Figure 1.

Figure 6 is a detail section showing the means for holding the rock shaft in posiw tion to keep the semaphore blade vertical.

In the embodiment of the device here shown there is disclosed a track rail 10 and a semaphore having a hollow stand 11 and provided at its upper end with a shaft 12 whereon is fixed a pair of semaphore blades 133 and lil, the former being longer than the latter. Supported between these blades on a lamp stand 15 is a lamp 1G. Project ing from the bottom portion of the longer blade is a rock arm 1i' which is connected by a link 18 witha rock arm 19 connected to a sleeve 20 fixed upon a rock shaft 21 supported in suitable bearings, not shown, in the bottom of the stand 11. @n the rock shaft 21 is also mounted a sleeve "7i-om which project pairs of arms 23, rollers 24 being revolubly mounted between said arms. `Within the hollow Ystand 11 are lugs 25 which support rollers 2G and springs 2T of the coil variety having their ends engaged on the

respective rollers

24 and 26 as shown in Figures 2 and 6, these springs acting to hold the arms 23 normally horizontal and thus also holding the rock arms 19 in horizontal position.

At the inner or track end of the rock shaft 21 there is provided a double rock arm 28 which normally rests in vertical position and has at its upper and lower ends laterally projecting pins 29. On these pins are mounted the slotted ends 30 or links 31 which pass through guardtubes -or pipes 32 fixed to the inside of the rail 10 by brackets or clips brackets the tube or pipe 32 is enlarged as at 34 and these enlarged portions contain pairs of'opposed compression springs 35, said springs bearing at their adjacent ends onf'a collar 36 on the vlink or rod 31. Between other pairs of brackets 33 the rail is cut away as at 37 and pivoted to a block 38 below this cut away portion is a rock arm 39 carrying at its upper end a roller i0 located in the gap formed by the cut away of the rail. This arm 39 is guided by a guide bar 41 and the rods or links 31 are connected to a strip 12 surrounding the respective arm 39. It is to be observed that there may be a number of these rollers 40 and, as shown in Figure 1, the track arn rangement extends in both directions from the semaphore stand. In operation a trainv approaching from the right of Figure 1 will engage, with its wheels, the rollers Ll0 and this will cause the arms 39 to rock to the left and thus, through the rod or link 31, actuate the rock shaft 21 and thereby oscillate the semaphore blade 13. At night when the lamp is lighted this oscillation will alternately cover and uncover the lamp thus causing a flickering thereof. It will be Betweencertain pairs of these i ill) (i ii noted that, by the peculiar arrangement of the slot end 30 the track apparatus on one side will operate without moving the apparatus of the other side and that, alter a train passes the semaphore actuating` the track apparatus beyond the semaphore will not operate the latter.

There has thus been provided a simple and eilicient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction ot the invention without departinro)` from the inaterial spirit thereof. lt is not, therefore, desired to com'ine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is:

l. The combination with a semaphore stand and its blade; of railroad track, and track supported means for repeatedly oscillating said blade including a rock shatt having operative connection to said blade and having a rock arm at one end, a rod having a pin and slot connection to said rock arm and supported adjacent a track rail, and a plurality of levers each pivotally connected to said rail and projecting thereabove for engagement by the Wheels of a train, said levers each being connected intermediate its ends to the rod.

2. The combination with a semaphore stand and. its blade, of railroad track, and

`track supported means il'or repeatedly oscilating said blade including a rock shaft iav'- ingoperative connection to said blade and having a rock arm at one end, a rod having a pin and slot connection to said `rock arm and supported adjacent a track rail, a plurality of levers each pivotally connected to said rail and projecting' thereabove for engagement by the wheels of a train, said levers each being connected intermediate its ends to the rod, and spring means normally holding said rod in position to elevate the vfheel engaged ends 0i" the levers.

3. The combination with a semaphore stand and its blade; oi railroad track, and track supported means for repeatedly oscillating' said blade including' a rock shalt having` operative connection to said blade and having a rock arm at one end, a rod having a pin and slot connection to said rock arm and supported adjacent a track rail, a plurality of levers each pivotall;Y connected to said rail and projecting thereabove for engagement by the wheels of a train, said levers each being connected intermediate its ends to the rod, spring means normally holding' said rod in position to elevate the wheel engaged ends of the levers, and other spring means normally holding` the semaphore blade in vertical position,

l. In combination, a track rail, a semaphore stand adjacent said rail, a shaft in the upper parlJ of said stand extending' transversely thereof', a blade iiXed on said shaft, spring means normally holding said blade raised in vertical position, a rock shaft extending,` between the rail and stand, corresponding rock arms on said shafts, a link connecting; said rock arms, a double rock arm on the end of the shaft adjacent the rail pins projecting' from said double rock arm adjacent its ends, rods supported from said rail and extending' in opposite directions from the rock shaft, slotted ends on said rods engaging' said pins, levers for each rod each having` its lower end pivotally connected with the rail and having its upper end provided with a roller projecting above the rail head said levers each being connected intermediate its ends to a respective rod, and spring means normally holdingr said levers in vertical position.

In testimony whereof I aiiiX my signature.
