RAILWAY SlGNALlNG-LANTERN.

'.SECIFICATIN forming part of Letters Patent No. 476,585, dated J' une 7, 1892.

Application filed January 2l, 1892. Serial No. 418,759. (No model.)

To @ZZ whom, it may concern,.-

Beit known that I, GEORGE E. VARREN, a citizen of the United States, residing at Detroit, in the county of 'Wayne and State of Michigan, have invented certain new and useful Improvements in Railway Signaling-Lanterns, of which the followin gis a speciiication, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in railway signaling-lanterns; and the invention consists in the peculiar construction of the lantern casing and lenses, together with vibratory colored shutters, with actuating mechanism for 'moving said shutters between the lamp in the casing and opposite pairs of the lenses; and the invention further consists in thc peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described.

In the drawings, Figure 1 is a side elevation of my improved signaling-lantern supported upon a standard as in use for railwaysignaling, and showinga lantern designed for what is kn oivn as a diamond crossing. Fig. 2 is a horizontal section on line a: @c in Fig. l. Fig. 3 is a vertical central section. Fig. 4 is a bottom plan view showing the diierent positions of the operating-levers.

A is a cylindrical casing secured to abasc B, having the usual inclined trap or Waterstrip C. This casing is supported upon a standard D, secured to a post E, beside a railway-crossing, the construction herein shown being designed for the so -called diamond crossing-fi. e., one in which the tracks cross each other at an acute angle.

The casing A is provided with the circular hoods E F', arranged in line With one track on opposite sides, and with hoods G G', arranged in line with the other track upon opposite sides of the casing. These hoods connect With the interior of the casing and are provided With suitable lenses Il, of plain or colorless glass.

I is a lamp centrally arranged in the casing, so as to be in line with the various exit-openings connecting into the hoods.

lVith the construction thus far described for the lamp, trains approaching in any direc,- tion on any track Would have a White signal exposed, indicating that the track was clear.

Now in order to stop a train on one track while the trains were approaching or crossing on the other, I desire to have colored shutters interposed between the lamp and that pair of lenses designed to signal the trains upon the track upon which the trains are to stop, leaving the colorless lenses exposed on the track upon which the trains are to continue in motion. To effect this with a simple construction, and yet one which will be efficient under all circumstances under which such lanterns are placed, I have devised the following mechanism a b are shutters of colored glass, (ordinarily red glass is employed,) provided at one edge with hubs c, adapted to engage upon the shafts d, arranged on opposite sides of the casing between the hoods or between the apertures which lead to the hoods, as plainly shown in Fig. These shafts are arranged in the angular extension f and are journaled in tubes g, connecting said extension with the inclined flanges C, and at their upper ends engaged into nipples 72., formed on the top of the angular extensions, as plainly shown in Fig. 3. These shafts d are provided With a crankarm i, each slidingly engaged in aperturesin the blocks j, having the bolts 7c journaled in apertures in the cross-bars Z, secured to the head m of the actuatingshaft n, so arranged that by a rotation of the shaft n the arms Z will be turned, rocking the shaft d and swinging the shutters b across one or the other pair of lenses.

In Fig. 2 I have shown the shutters arranged across the lenses in the hoods F F, so that the tracks toward which those lenses are turned leave the red light exposed, while the White light will be shown through the lenses in the hoods G G. A similar rotation of the shaft will rock the lenses to show a red light through the lenses G G and White light through the lenses in the hoods F F.

.I is an ordinary signal-board secured to the shaft, designed to give the signal in the daytime.

Itis evident that as the hubs c slidingly engage on the squared portion e of the shaftzro:

any ordinary displacement caused by the vertical movement of the shaft 'n or rise or fall of the lamp in relation to that shaft will not aifect the actuation of the mechanism.

It will also he observed that all the operating mechanism is seen rely housed beneath the lamp or within the lamp-casing', so that it cannot he affected hy storms er ice. The whole construct-ion gives ine a siingle and efficient signaling-lamp, which can be applied to crossing` at. any angle greater er less than right angle, or for right-angled crossings, and itean he applied to any other hind of signallainp in which it is desired to change the eolor to he exhibited.

I overcome a serious objection which has heretofore existed in revolving` the lainncase itself by having` the lamp stationary and inoving the shutters. lt has been Vfeund frequently that peratoi's in throwing the entire lamp would by the centrifugal force, thelainp being' heavy, throw it from its support with consequent danger to trains and the necessityofreplacingthelanin. Thepeculiaractnating,` mechanism which l employ is such to prevent the shutters troni strihing'theeasing', as the hlocksj liniit the inoveinent ot' the crank-arms, and the shutters are so arranged that, at the extremity of their strette they do not rest against the sides or" the lantern.

That l claim as my invention is l. In a railway signailing-lantern, the conihination, with a stationary easing` having a series of apertures and a lamp within, ot shutter of colored glass pivoted between two of the apertures and adagted to he rocked to cover either one or two of the apertures, sul)- stantially as described.

2. ln a railway signaling-lautern, the conihination, with stationary casing having two sets of apertures adapted to he arranged in line with crossing` railways and a lamp within, of two shutters of colored glass oppositely arranged within the easing', and operating mechanism adapted to niovc said shutters across either of the two sets, substantially as described.

in a railway signaling-lantern, the coniliination of the stationary casing having two sets of apertures adapted to he arranged in line with crossing` railways and alainp within, of the shutters Z), ot colored `class, oppositely arranged within the casing, the shafts (l, on which said shutters are secured, the cranks on said shafts, the actuating-shaft, and connectien `netween said actuating-shaft and crankarnis, substantially as described.

-l-. in a railway signaling-lantern, the conihination, with the stationary casing,` having apertures and a lamp within, of the shutter a, the squared huh c, the shafts (l, having' a squared portion engaging in said huh, a bearing in which said shatsare journaled, cranks t the end of said shafts, hlocksin which said cranks slidinfrly engage, arins in which said hloclis are pivoted, and ashaft lor rockingr said arins, substantially as .lescrihed.

in testimony whereof l aili v iny signaturcin nresenee of titre-witnesses.
