TRAIN-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 352,567, dated November 1,6, 1886.

f nppiicmion ined February 24,1886. sei-iai No.y 193,037. (No model.)

. To all whom it may concern:

Be it known that I, JOHN H. PARsoNs, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Train-Signals, of which the following is a speciiication.

Freight-trains are required to carry signals visible both from the front and rear of the train, for the purpose of informing the engineers of other trains of their positions, and also of enabling the engineer of the train carrying the `signal to know whether one or more cars on the rear of his train have or have not become detached. 'Ihese signals are usually carried by the Caboose, located at the extreme rear of the train. The usual signal has been a lantern fixed upon the outside of the car. This from its location has been 'inconvenientd to control, and cold weather or storms frequently interfere with the burning of the lantern.

My present invention has for its object the placing the signals so they shall be accessible from within the car and readily operated without leaving the car, and to protect the signals from the effects of cold and storms by bringing them within the induence oftheheat of the interior of the car. For this purpose I pro- 'pose to introduce these signals into a trainindicator box, such as I have shown in my previous patent, N o. 148,844, dated March 24, 1874, and place that box in direct communication with the interior of the car on which it claims.

In the drawings hereto annexed, forming part of this specification, Figure 1 is an outside perspective view of the usual raised deck of a caboose with my indicator and signalbox mounted upon it. Fig. 2 is avertical cross-section of the box, showing two of the signals, theindicator-sash, and other details. Fig. 3 is an interior View of the car, showing an arrangement for operating the signals from below. Figs. 4 and 5 representativo-part clamp in which the ends of the ropes controlling the signals may be fastened, and which is provided with a ring or handle for engaging with a hook fixed to the side of the car. Fig. 6 is a front view ofthe sash, showing the indicatorletters. Figs. 7 and 8 are respectively horizontal and vertical cross-sections of the same on lines 7 7 and 8 8, Fig. 6; and Fig. 9 is a side view of the casing ofthe window, showing the groove vin which the sash slides and the manner in which it is cutaway to permit the introduction of the sash from below.

The indicator-box l may be of any desired material; but sheet metal will probably be found the most convenient, and is placed/transversely of the length of the car, facing toward the engine and toward the rear of Ithe train. The shape I have shown, having at each enda semi-cylindrical portion for the location of the signal-lamps, will probably be found advantageous, it being desirable to duplicate the signals, placing one on each side ofthe car,so that the engineer may look back on either side of the train/for the signal, and also to increase the probability of the signal being seen by the employs at the stations and along the track.

It is provided with a hinged top, l2,. carrying a chimney, 3, to provide for the escape of the products of combustion of the lamp placed in the center to illuminate the indicator-` window. The sash is of the saine construction in general as that shown in my previously-re ferred-to patent, being provided with overlapping retaining strips 4, between which andthe glass window-panes are retained the plates 5, carrying the .figures and letters for indicating the number of the train and the number of the train-section, as fully described in the spcccation accompanying my Letters Patent 148,844, above referred to. Forthe purposes of this application it is merely necessary to observe that these gures and letters are arranged toinform the employs of roo the roads at the stations passed by the train as to the number of the train, and, where the train is run in several sections, as to the nurnber of the section, so that the switches and track -signals may be placed accordingly. These strips 4 are bent in against the sash at their lower ends, so as to afford a vertical sup-v port for the plates. A handle, '9, is att-ached to each sash for conveniently moving it, and the projection 33 is provided on each of the plates 5 for the same purpose. The inner side,

10, of the groove of the casing in which the sash slides is cut away, as shown in Figs. 2 and 9, at its lower end, and is beveled outwardly, so as to permit the sash to be removed from below, as well as from the top, by opening the cover 2. To prevent rattling of the sash' in the casing, or its displacement, springs 11 are provided,of su ch a shape as not to inter- -ing the required signals when brought, re-

spectively, before the opening 15 in the side K of the box to the side of the indicator-box.

This metal plate is pivoted at 32. A wire, 16, passes arou'nd the outer edge of the plate 'and kis bent into two projecting points, 17

JJJJ Mtworpieces of the shape shown in Figs. 4 and 5, being provided with two grooves for the reception of the ends ofthe two cords respectively. The grooves are of such a depth that when the two pieces are fastened together by means of screws 24 the cords will be securely.

clamped between them. One. of `the parts of the clam'p is provided with a handle-shaped attachment or ring, 25,adapted to engagewith a hook, 26, fixed upon the side of and within the deck. The frame carrying the glasses, being pivoted on one side of its center of gravity, will normally assume the position shown in Fig. 2, in which the red or danger signal is given, the glass 14 being of that ucolor, and over the opening of the box. 13, is used for giving the caution-signal, usually green, and when this is to be displayed the position of the signal-frame is reversed by drawing down the clamp and causing itto engage with the hook 26. It will be noted that when the clamp is attached to the cords it can readily be adjusted to the proper points thereon, so that the cords will be taut when the several parts are in the positions shown in full linesin Fig. 2, and when the clamp is drawn down to the position shown in dotted lines the signals will be thrown.

VA11 alternative arrangement for operating The other glass, l

the signals is shown in Fig. 3, where the cords from the two signals are united, as shown at 2.7, and a single cord carried down over pulleys to a lever, 28, pivoted-to the side of a car. A catch, 29, is provided for holding this lever in the position corresponding to the caution position of the signals. These two positions of the lever are indicated by letters or appropriate colors on the side of the car, so that the attendant in the car can tell by the position of the lever the character of the signal being disp/layed.

4It is important that the normal position of the signal, or that to which it is brought by the action of gravity,should be the danger position, since the breakage of the rope or other derangement of the apparatus will at once occasion investigation and repair.

I have not considered it necessary to show both sides of my indicator-box, since they are made precisely alike and are provided with plied to the outside of the indicator-box, as

shown by crossed shading lines in Fig. 1, about each of the signal-openings, to serve as a daysignal, forthe purpose of enabling the engineer to know whether or not he has lost any cars from his train. The usual lamps, one of which is shown at 30 in Fig. 2, are placed inY the indi- Gator-box, one at each end, and opposite to the signal-openings. Windows or bull s-eyes may be placed in the convex' ends of the signal-box, in order to indicate to persons situated on the side of the track the passage of the train, if desired, as shown in Fig. l.

I wish it understood that I do not limit myself to the use of the particular colors herein described or to the exact form and construction of the various appliances, since many equivalents might be readily devised which would be equally within my invention.

I claim- 1. An indicator-box mounted upon the top of a car and communicating freely therewith, and provided with removable plates for displaying the numbers of the train and section, with signal-lamps mounted in said box, one at each end thereof, colored transparent signal-plates pivoted one before and one behind each lamp, and mechanism connected with each of said plates and passing to the interior of the cars, whereby the signals may be simultaneously shifted, substantially as and for the purpose set forth.
