The rollfrom the subjoined description, reference beers 6 and 7 are of ordinary construction and 90 4o ing had to the accompanying drawings, in are journaled at their ends in a side of the whichease and in the partition 10, which divides Figure l is a perspective view of a stationthe case into the compartments 3 and 4:. The indicator constructed in accordance with and journals 11 of the rollers 6 and 7 project beembodying the essence of the invention, the yond the partition 10 and receive beveled 5 5 cover to the compartment inclosing the actugear-wheels 12 and 13, which are constructed ating mechanism being removed and a porto slide upon the said journals, but turn theretion of the cover for closing the compartment with when positively actuated, so as to impart in which the name-bearing belt or canvas opa rotary movement to the said rollers for crates being broken away, a portion of the winding the belt or canvas 5 thereon. Each I00 vertical partition being broken away to disof these beveled gears 12 and 13 has a hub close the mechanism for controlling or checkportion in which is formed an annular groove 14, into which extends the free end of an arm 15, carried by a rod 16, so as to move the said beveled gear on its journals to throw the rollers in and out of gear in the manner hereinafter to be fully set forth. A vertical shaft I-I, suitably journaled near its ends in brackets 17, secured to the partition 10, has an eccentric or crank 18 at each end, with which the rod 16 makes connection. The crankarms 18, at the opposite ends of the shaft H, are disposed so as to occur at diametrically opposite points, so as to impart a reverse movement to the beveled gears 12 and 13. A tension-sprin g 19 is provided for each roller 6 and 7 and is adapted to be pressed upon by the end of the rod 16, which projects through the partition 10. This tensionspring 19 forms a brake and operates to check the free movement of the roller out of gear, thereby preventing the belt or canvas 5 from paying off or unwinding too freely from the said roller. A second vertical shaft 20, j ournaled in bearings provided at the top and bottom of the case, has beveled gear-wheels 21 and 22 at its opposite ends to mesh, respectively, with the beveled gear-wheels 12 and 13. This shaft is operated by any suitable train of gearing or other motive power, so as to impart a rotary movement to the rollers 6 and 7 to wind up and move the belt or canvas 5 in the proper direction, according to the movement of the car or train.

The belt or canvas 5 may be of any suit able construction usually provided in this class of devices and has the names of the stations printed transversely thereof at proper intervals, so as to be brought in register with the openings 8 and 9 in the cover 23. The edge portions of the belt or canvas 5 are reinforced or thickened, as shown at 24, and are provided with a series of perforations 25 occurring at regular intervals, so as to receive the pins 26 of a controlling-wheel 27. There are two of these controlling-wheels 27, one for each edge of the canvas 5, and they are mounted upon a transverse shaft 28. A resistance-roller 29 is located opposite and acts, in conjunction with each controlling-wheel 27, to insure engagement of the pins 26 with the openings 25. These resistance-rollers 29 are idlers, and between them and the controlling-wheels 27 the canvas or belt 5 passes. A disk 30 is provided on the inner end of the shaft 28 and has a notch 31 in its peripheral edge to receive the bent end of an arm 32, by means of which the movement of the said shaft 28 is stopped the instant the name of the station comes opposite the slot or opening in the cover 23.

The reference-nu1neral 33 indicates a suitable train of gearing or motive power, by means of which the parts are set in motion to operate the belt or canvas 5. As shown, this train of gearing 33 approximates the movement of a clock or similar mechanism, the initial power being derived from a coilspring 34 in the well-known manner. A shaft 35 is suitably geared with the post or arbor upon which the coil-spring 34 is mounted, so as to be rotated therefrom. A beveled gearwheel 36 on the end of the shaft 35 meshes with a corresponding gear-wheel 37 on the shaft 20 and transmits motion to the latter shaft when it is desired to operate the canvas or belt 5. A toothed wheel 38 is keyed upon the shaft 35 and is adapted to be engaged by the bent end of an arm 39, mounted upon a shaft 40. This arm 39 is weighted, as shown at 41, to cause its automatic engagement with the toothed wheel 38 when said shaft 40 is released from the influence of the disk 30.

A gong or alarm 42 is provided and sounds during the movement of the belt or canvas 5, so as to attract the attention of the passenger and inform him of the name of the next station. This alarm is suitably operated from the train of gearing in the ordinary manner 5 of alarms provided for clock and other similar movements. The end of the shaft 40 is provided with an arm or lever 43, which is actuated by any convenient means to allow the actuating mechanism to move the belt 5, so as to expose the proper name of the station through the opening in the casing.

For street-railway cars and similar vehicles and public conveyances the ordinary bellpull cord or other convenient means may be provided and attached to the arm 43 so as to turn the shaft 40 and disengage the bent end of the arm 32 from the notch in the checkwheel 30 and at the same time disengage the bent end of the arm 39 from the toothed wheel 38, so as to permit the movement, and on the release of the cord to stop and check the position of the belt, whereby the proper name of the required station is exposed through the opening in the casing;

For steam-railway cars and others propelled by steam, compressed air, and like motive power a cylinder 44 will be provided and located so that the stem 45 of its piston 46 will engage with the arm 43 and allow the actuating mechanism of the indicator to move. A pipe 47 will communicate with the lower end of the cylinder and be under the control of the engineer or conductor, so as to supply the steam, compressed air, or other fluid to the cylinder to actuate the piston when it is required to change the name of the station exposed to view. A retracting-spring 48 is located in the upper end of the cylinder and confined between the piston 46 and the head of the said cylinder, so as to act in opposition to the steam or other operating fluid, so that when the latter is shut off the said spring 48 will regain itself and return the parts to a normal position.

From the foregoing description it will be seen that when the shaft 40 is turned so as to release the arms 32 and 39 from the wheels 31 and 38 the movement will operate, and by means of the mechanism hereinbefore specified will sound the alarm 42 and rotate the shaft 20. Inasmuch as. only one of the rollers 6 and 7 is in gear with the shaft at the same instant, it is manifest that the roller so geared is the one which will receive positive movement. The shaft lO having been set in motion will be held in such relative position that the bent end of the arms and 39 will be out of active operation by means of the bent end of the arm 32 riding upon the periphery of the disk 30. The instant the notch 31 comes opposite the bent end of the arm 32 the weight l1 will cause the bent end of the arm to enter the notch 31, and at the same time the arm 39 will engage with the wheel 38 and check the movement of the train of gearing It will be seen that the movement of the belt or canvas 5 and the train of gearing is checked at the same instant. Hence there can be no straining of the actuating mechanism. After the car or train has reached the end of its travel the roller 6 or 7, previously out of gear, will be now brought into gear, so as to reverse the movement of the belt on the return trip of the car. This is effected in a convenient manner by means of a rod elf), connected at its inner end with an arm on the shaft II and having its front end portion projected through the casing, so as to be readily accessible to reverse the motion of the belt 5. Any convenient locking mechanism may be provided to secure the rod 49 in the located position. As shown, aplate 52 is firmly attached to the cover of the case and is notched in its edge for the passage of the said rod 49, and a latch 51 is pivoted to the said cover and acts in opposition to the plate 52 to bind or grip the rod 49 and secure the same in the required location.

While the construction and arrangement of the parts herein shown and described are preferred, it will be readily understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

The shaft &0 is provided with an arm 53 to engage with a wheel 54 of the movement and hold the latter in check during the interval between the initial movement of the shaft 40 when tripped and the release of the same by cutting ofi the steam or releasing the pullrope, by means of which the said shaft -:L0 is tripped. By this construction if the shaft 40 is actuated and not instantly released, the arm 53,by engagement with the toothed wheel 54:, will prevent any motion of the movement and will hold the latter motionless until the said shaft 40 is released from the means by which it receives its initial movement. Thus should the shaft 40 be tripped and held at the limit of its trip movement the operating parts of the device will not be actuated *until the said trip mechanism is released.

On reference to Fig. 1 it will be seen that the cover is provided near its lower end with an opening 55, which corresponds in shape to the openings 8 and 9. The opening 9 is centrally disposed, and the name of the station arrived at is disclosed through the said opening. The names of the next stations en route are exposed through either of the openings 8 or 55. \Vhen going in one direction, one opening, as 55, is concealed by a removable shutter 56, and the names of the stations are disclosed through the opening 8. On the return trip the shutter 56 is moved and arranged so as to hide the opening 8, thereby permitting the names of the stations in advance of the one arrived at to be exposed through the opening 55.
