This invention relates to that class of signaling devices used in connection with what is known as the block signal system for governing the movement of trains, the road being divided into sections and the signal apparatus being so placed as to control each section in regular` order.

Figure 1 is a perspective; Fig. 2'a vertical longitudinal section broken away, the cap being removed; Fig. 3, a view ofthe signal slides and cages; Fig. 4, a horizontal transverse section in the plane a: w, Fig. 1. Fig. 5 is an elevation, with one side of the outer inclosing-case removed, showing the interior; and Fig. 6 a hori-A zontal transverse section in the plane y y, Fig. 5.

Referring to the drawings, A represents an outer i'nclosing-case of a rectangular form, having four equal sides; but may be of any other desired form that convenience may require, the inclosing-case serving the purpose of supporting and protecting the signal devices l from atmospheric changes. The lower portion of one side of the outer case consists of the hinged door A', which conveniently admits of access to the interior, in order to replace or remove the signal-lamp, and for such other purposes as may be required to keep the apparatus in proper working order. The lower inclosed end is provided with elongated apertures for the passa-ge of the vertically-sliding signal-boards B B as they are adjusted to different positions. The upper end is inclosed by the metallic ventilator cap or hood A2, which is perforated for the escape of the gases from the signal-lamp, placed on the inside bottom of the apparatus, as indicated by the dotted lines in Fig. 5 of the drawings. The two sides of the inclosing-case, adjacent to the hinged door A, are prpvided with the circular openings C2 G3, covered with glass, forming a bulls-eye, which reflects the light in both directions on the track. The smalleropening, B6, is placed in that side of the outer inclosing-case that is opposite the hinged door A',

said opening being covered withnl glass, and making proper provision for the signal-operator to observe the condition of the lamp, and whether the proper signal is being displayed.

lhe outer casing, A, is ordinarily constructed of wood and painted with any color desired. On the inside of this case is placed the metallic ilue C, leaving considerable space all around between the inclosed and inclosing walls for the reception and movement of the signal devices, as shown in Figs. Zand 5 of the drawings. This iiue is of a form corresponding tothe outer case, and is provided with a rectangular opening closed by the vertical slide G. `The signal-lamp is placed on the inside of the metallic ilue, and is thus doubly protected from the inclemency of the weather. The upper end of this flue is contracted, andprojects above the upper end of the outer inclosing-case into the metal cap A2,` which is` provided with the perforated escapetube A3, as shown in Fig. 5 of the drawings. The lower part of the metal ilue C is provided with circular openings corresponding to similar openings in the outer inclosing-case, A. rllhe adjustable signal-boards B B are adapted to move in a vertical plane on the inside ofthe inclosing-case A. The lower ends of the signal-boards lare provid ed with the circular openings B2 B3, which correspond to similar openings in thel outer case, A, andthelinner case or metallic flue, C, the different openings being opposite Veach other when the signal-boards are vin their normal position, as shown in Fig. l of the drawings, a white light being displayed from both sides of the apparatus. The signal board or slide B is painted red, the upper end being formed with the square open signal-box D, as shown in Fig. 3 of the drawings. The upper end ofthesignal-board Bforms one side of the square bon D, which is open at both ends and incloses the' metallic rlue C, that forms a guide for the vertical moving signal devices. The upper end of the signalboard, forming one side of the box D, is provided with the rectangular rabbeted recess a,

IOO

the opposite side of the box being provided with a similar recess. These recesses are intended to receive and retain colored signalsheets of glass, which slide into place from the upper end. The color of the sheets of glass B4 in the box D is red, and that is the signal displayed when the box D is dropped down into the same horizontal plane with the signal-lamp, and is seen from both sides, the signal-board being the day signal. The companion signal-board B' and the signal-box D' are of the same general construction as the box just described, the box D' being somewhat larger in order to slide over the box D, thus forming a box within a box. The box D' is provided with the glass sheets B5, of a green shade, the day signal-board being ofthe same color.

These signal devices are operated and controlled by, means ofthe cords a' a'-, which pass over the sheaves c 3 ai, as shown in Fig. 2 of the drawings. rlhe inside ends of these cords are connected to the cross-bars b b', attached to the upper ends of the signal-boxes, while the opposite ends pass out through perforations in the cap A2, and lead to the place where the device is to be operated from. The sheaves a3 a* are journaled in the brackets b2 b, which are inserted in the under side of the bridge E, which is supported by the vertical ends d d', attached to the upper end of the outer case, as shown in Fig. 2 of the drawings. By slacking on the cords the signals will drop by force of gravity, and are easily and conveniently returned to their normal position by means of the controlling cords. The signallamp always remains stationary, and any number of different-colored signals can be displayed from the same apparatus by simply increasing the dimensions of the outer inclosing-case and multiplying to any extent the number of signalboxes on the inside, thus forming a double track block and train-order signal, whereby one track can be blocked and the other clear, or the block-signal can be displayed for one track and train-orders for the other, or both trains blocked, or train-orders for both tracks, or train-orders for one track and the other clear, as may be required at the particular time.

The apparatus is easily and cheaply constructed, the colored glass easily replaced if broken, no parts of the device are liable to get out of order, and the different signalglasses are protected from smoke and dust.

If desirable, the apparatus may be so constructed as to display the day-signal boards in a horizontal plane.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isa 1. In a railway signal apparatus, the combination, with an outer inclosing rectangular case provided with transparent .openings at the lower end and a cap and escape-tube at the upper end, of a rectangular metallic flue arranged centrally on the inside of said case, said flue being provided with corresponding openings and forming a receptacle for a stationary lamp, and the square signal-boxes D D', arranged one 'within the other and inclosing said flue, and adapted to have a vertical movement on the interior of said case, substantially as set forth.

The combination, with the inclosing-case A, of the day-signal boards B B', adapted to have a vertical movement on the interior of said case, and provided on the upper inner ends with the signal boxes or cages D D', substantially as d escribcd.

3. The combination, with the case A, of the signal-boards B B', adapted to project from the lower end of said casein a vertical plane, and the squaresignal-boxes D D', secured to the interior upper ends of said boards and adapted to move simultaneously therewith, said boxes being open at the top and bottom and. arranged to have an independent adjustment relative to cach other for the purpose of displayingl different signals, substantially as set forth.

4. The combination, with the signal-boards l
