STATION-INDICATOR.

sPEoIFIcA'rIoNrormin part of Letters Patent No. 499,895, dated June 20,1898. Application filed September 19 1892- Serial No. 44 3 .(N0 model-l This invention relates to that class of indi-,

cators which are employed in railway cars and street cars to indicate the different stations or streets which the car is approaching- The invention has for its object certain improvements below described and claimed, prominent among which is to automatically operate the signal, by means of a lever coming in contact with an inclined projection at the side of the track.

In the drawings forming a part of this specification, Figure 1 is a side elevation of the indicator mechanism, which in use is fixed in an elevated position upon the wall of the car.

Fig. 2 is the same as Fig. 1, with one side of the frame removed, showing the inside construction. Fig. 3 is an elevation looking against Figs. 1 and 2 from a point at the right. Fig. 4 is an enlarged sectional view of lettered details on line 3-3, in Fig. 1, looking Fig. 5 is an elevation of said parts, looking from a point at the right of Fig. 1. Fig. 6 is an enlarged broken view of lettered details fronii'Fig. 3. Fig. 7 is a broken sectional elevation on line 4-4, in Fig. 8, looking from a point at the right, illustrating the mode of operation; and Fig. 8 is a section on line 22, in Fig. 7, looking from a point at the left.

Referring to the lettered parts of the drawings, A B. show the side walls of the frame, in which the shafts, C D,have bearings, as in Figs. 1, 2 and 3.

At E are shown belts, wound upon these shafts O D at each end, which belts bear the names of the stations or streets and in the operationrwind on one shaft and unwind from the other, passing during said operation back of an opening, F, stopping at said opening and presenting the name of the station or street, as illustrated in Figs. 3 and 6 by the words Woodward ave. These belts are made of flexible material, consisting of two strips separated from each other, and attached to each other by means of posts or bolts, 0, leaving a space between said posts for the insertion of cards bearing the names of the stations or streets, as shown in Fig. 6, said cards being passed through the slot in the side of the frame, as shown at e, in Fig. 1.

The shafts D and C are provided at one end, outside of the wall, A, with the gears, G and H. Between these gears G and H is a gear I, meshing therewith, as illustrated in Figs. 1 and 3. The gears H and I are provided with ratchets, a and b, and with arms, 0 and e, radiating from the axes of said gears. These levers, c and e, are pivotally connected together by a bar, f, Fig. 1. Each of the levers ;c e is provided with a pivoted dog, It i, which dogs engage the ratchets a b. The dogs, h 11, are provided with rearward extensions j 7t. vCentrally pivoted to the arm, f, is a rocking lever, m, having elongated slots in each end.

At n is a forked lever, pivoted at 0 to the wall of the frame, A, each end of said forked lever being loosely inserted in the elongated slots of the rocking lever, m. The forked lever, n, is provided with a handle, 19. The Ohj ect of this rocking lever and the forked lefver connected therewith is to reverse the mechanism at each end of the route. trate, referring to Fig. 1, the rocking lever, m, is in such a'position that the dog, h, is engaged with the ratchet, a, and the dog,j, is disengaged from the ratchet b. When in this condition, (as will clearly appear by the description of the operating means and the operation hereinafter) the belts, E, will wind on the ends of the shaft 0, and unwind from the shaft D. When the car starts to run in the opposite direction the operator, by taking hold of the handle, 1), will trip the dogs, causing the dog j to engage the ratchet b, and the dog h to be disengaged from the ratchet a. This is accomplished by bringing the rock- To illusing-lever, 'n, in contact with the rearward extensions, j and k, of the dogs. Motion is first imparted to the shaft 0, and from its gear H, through gears I and G to shaft D. The upper end of the arm f, in Fig. 1, is provided with an elbowed arm, 5, which enters the case,

t, and operates a pneumatic alarm hell, by 100 which wheel 3 comes in contact. with the inelined block, M, at the propertime to indicate the station or street which the car is approaching. This elbow lever, 2, is connected with the lever, f, in Fig. 1, by means of a cord, chain or cable, 7'. The end of this cord,chain, or cable rwhich is connected with the lever 2, is provided with a spring,4 and is attached in an elongated slot in theend of said lever, as in Figs. 7 and 8. The object of this springand elongated slot is to prevent any jar which might be imparted to the indicator 1116011311.

ism by the contact of the wheel 3 with the rail of the track from operating said mechanism until the proper.time,.when said wheel will come in contact with the inclined block, M, at which time the movement of the lever, 2, is sufficient to overcome the yielding eifect of the spring, 4, and operate theindicator.

Just back of the opening, F, to which the name of the station or street is presented, is a belt-tensioning device, consisting of two rollers, 6-6, mounted in aframe, 7, which has end projections passing out through'slots, 8,.

in the sides, A B, of the frame, to which pro jections are attached spiral springs, 9, by means of the bolts, w, the ends of which bolts, w, pass loosely through brackets, T, which brackets areattached to the sides, A B, of the frame. The object of this tensioning-device is indicated in Figs. 1 and 2, it being so placed that its rollers will come in contact with the A inside of the belts, E E, and bear against the.

same with a spring pressure, so as to hold said belts out near the opening, F, where. the names of the stations or streets are presented.

In Fig. 1 an arrangement isshown for presenting rules and regulations of the company operating the cars, which consists in an endless belt, S, carried by a roller, having a gear 5 Z, meshing with the gear G. The instructions are'on the face of this endless belt and are presented at the front side (the right hand side in Fig. 1) at the time the station or street is indicated. This latter device may be employed or not, as desired in connection with the station and street indicator.

In the operation, when the car approaches a station or street, the wheel 3 runs on to the inclined block, M, tripping the lever2 and in turn operating the lever f, which operates the radial arms, a e, causing the dogs Hz to turn. the shafts C D a distaneeof one space,which distance would be the width of one of the in-' dicator cards bearing the name of the station; l

or street. When the car made its return trip in the other direction, the operator, by means of the handle, p, would trip'the lever, m, and disengage the dog it and engage the dog 2' would of course travel in the opposite directioinnaming the stations or streets in the rei verse orderdllning the return. trip. This mechanismfor carrying the belt and for reversing the direction in which it travels may be used in connection with any suitable opidea being illustrated. in Fig. 6. r
