SIGNALING DEVICE.

SPECIFICATION forming part of Letters Patent No. 465,768, dated December 22, 1891.

Application tiled April 11, 1891. Y Serial No. 388,570. (No model.)V

To aZZ whom it may con/cern..-

Be it known that I, FRANK ST. CLAIR, residing at Manchester, in the county ot' Hillsborough and State of New Hampshire, `have invented an Improved Signaling Device, of

which the following is a specification.

This invention relates to an improved signaling device adapted to be placed at the entrance of covered bridges, tunnels, and the 1o like to warn the brakeman or other operator on top of the car of the approach of danger.

Heretofore scattolds have been erected with one arm to overhang the track and a series of ropes depending from said arm, which strike I 5 the brakeman and warn him. Devices of this character, however, are liable to become inoperative during a storm or high wind, as the ropes may be blown around and over the arm. 4zo The object of my invention is to provide a device that shall be operative at all times, and one that will give an audible signal to brakemen other than those operated upon.

lVith these objects' in view my invention 2 5 consists in certain details of construction and combination of parts, as will be more fully hereinafter described and claimed.

In the drawings forming a part of this specification, Figure 1 is a perspective view 3o of my improved device as applied. Fig. 2 is a front elevation of the same; and Fig. 3 is a top plan View, the position of the parts when he device is operated being shown in dotted mes. 3 5 In the practical embodiment of my invention I employ a vertical postor standard A, which is placed on the ground about three hundred feet in advance of the entrance to thev bridge or tunnel. Near the top of said post is secured the horizontal beam B, projecting inwardly toward the track, and secured to the beam B and post A, is an oblique beam or timber C, the lower end of said timber being secured to. the post A near the center of the same. A beam or timber D is hinged to the beam C in parallel relation therewith by means of the hinges d, and to the upper end of said pivoted beam D is attached the horizontal arm E, which projects inwardly 5c over both rails of the track. This arm E is braced by a4 diagonal brace e. A rod F eX- tends obliquely inward and downward from the pivoted beam, and upon the lower end of said rod is secured a weight G, which is adapted to return the arm E to its normal position 5 5 after having been operated. A signal-gong H is secured to the forward or front side of the post A, and connected with the gong mechanism is an operating-arm H said arm working in a guide-staple 7L, secured to the beam 6o B. The inner end of the arm H projects as far as the pivoted beam D, and is provided with a catch or projection h', and the be'ani D is provided with an operating-dog h, adaptl ed to engage the said catch and operate the gong when the horizontal arm is swung outward or rearward. The outer end of the dog h is beveled, as at 71, whereby the catch h is permitted to resume its normal or operative posit-ion after the gong has been sounded. 7o rlhe operating-arm is slotted at t', and through said slotted portion is inserted a screw I, carrying a spiral spring i', which throws the arm back in place after the horizon-tal arm has returned to its normal position. As the arm E automatically returns to its normal position, the arm H is also returned to its normal position by the engagement with the catch h of the dog h,- or a suitable spring may be employed, if desired, to accomplish 8o this latter operation.

From the above it will be seen that a person standing on the car-roof will strike the horizontal arm E, which, being very light, yields easily and will not injure the person, and it will also be seen that an audible signal isalso given to the other brakemen. The Weight will return the arm to its normal position and it is ready again for operation.

Having thus described my invention, what 9o I claim as new is 1. The combination, with a vertical post, of a horizontal arm pivotally connected therewith, the pivots for said arm being out of verticalalignment, for the purpose described, a gong carried by the post, and means for sounding an alarm thereon when the arm is swung out of its normal position, substantially as set forth.

2. The combination, with the post, of the roo horizontal beam secured thereto, the oblique beam connectingthehorizontal beam and post, the oblique beam pivoted to the said connecting-beam, and a horizontal arm attached to the pivoted beam, and a 4Weight also secured thereto, substantially as shown and described.

3. The combination, with the post and rigid oblique frame, of a horizontal arm pivoted thereto, the Weight, the signal gong, operating-arm, operating-dog, set-Screw, and spring, 1o al1 arranged substantially as described.

In testimony whereof I afx my signature in presence of two Witnesses.

FRANK ST. CLAIR.
