cross-bars

26,27 and the said collars.

Located adjacent to the track rails 34, 35 are

lugs

36, 37, shown in detail inFig. 13,

which'said lugs each comprise a base portion 7o 438, adapted forv 'attachmentjto the cross-ties 3,9, and a horizontally curvilinear standard 40, formed on-the base portion and vertically extending therefrom, the connection between the base portion 38 andstandard 40 'being strengthened vby a web 41.' s

The'indicator proper is located inl the up.- per portionof a car-body 42, and comprises Ua frame 43, preferably made of` cast' metal, and shown in detail in Fig. 8, which said frame comprises' a top portion 44, adapted for vattachment to the car-body, and 'depending'portions'45, 46 integrally formed with the top portion 44, the said top portion being lightened byy cuttingaway a section thereof, asshown. I

Formed in the depending

portions

45, 46

are`

V apertures

47, 48, and formed on, or fixed to, the outer surfaces of the depending portions, concentric with said apertures and registering'therewith, are `

bearings

49, 50. Mounted for rotation Within

theapertures

47, 48, and

hearings

49, 50, is a shaft 51,- one lend of which shaft projects outside the bearf ing 49, and has mounted thereonfa wheel 52, the periphery of which wheel is faced with leather, rubber, or other substance capable of a' high degree of frictional contact with a contacting surface.

Located upon the depending portion 45, and extending outwardly therefrom, parallel to the projecting portion of the shaft 50, isa

headed bolt 53, upon which bolt is mounted a spring-yoke 54.

A contracting bolt 55 is transversely positioned in the yoke 54, and is adapted t0 approximate the sides of said yoke, and ca use the same to bind upon, and engage with, the periphery of the wheelA 52, the tension of the engagement being regulated by the variation of the bolt 55, relative to its seat.

Removably and replaceably mounted upon the shaftl, between the depending

portions

45, 46, and adjacent to the said depending portion 45, is a disk, orhead, 56, and removably and replaceably located on said shaft, adjacent to the depending portion 46, is a disk, or head, 57, said disks or heads, being of approximately the same diameter. Mounted upon the face of the head 57, adjacent to the depending portion 46, is an annular ratchetplate 58.

Fulcrumed on a stud 59 (Fig. l) is a lever 60 (Fig. 14), horizontally positioned for reciprocation, which said lever is provided with a spring-pawl 61, and adapted for engagement with the ratchet-teeth on the plate 58. Pivotally mounted on an adjacent support is a spring-actuated detent 62, adapted for engagement with the ratchet-teeth on the plate 58, whereby a reverse movement of said ratchet-plate is prevented. Located adjacent to the end of the long arm, of the lever 60, is a pneumatic cylinder 63 (Fig. l1), within which is mounted a piston 64 (Fig. 15), the lower end of the rod of which piston is bifurcated and pivotally connected to the said long arm of the lever 60. Fixed to, and depending from, the long arm of the lever 60, adjacent to the piston 64, is a rod 65, adapted for manual operation.

The cylinder 63 communicates with the cylinder 20 through the pipe 66, in the lower end portion of which pipe is mounted a checkvalve '67, comprising a casing 68 (Fig. 5), a transverse partition 69 in said casing having a vertical aperture therein, which said vertical aperture is normally closed by a vertically and horizontally movable plug 69* engaged by, and providing, a seat for a vertically positioned spring-retained valve-stem 70.

An induction port 7l is formed in the lower portion of the casing 68, and an eduction port 72 is provided in the upper portion of said casing, the aperture in the partition 69 providingcommunication between the said ports, the port 72 being normally closed by the plug 69,

A plurality of rods 73 are located transversely of, and supported in, the peripheral portions of the

heads

56, 57, respectively, on which rods are pivotally mounted for oscillation, relative thereto, a plurality of cards 74 (Fig. 12), which said cards bear upon one face symbols, designating the name, or number, of one of the streets crossed, or traveled upon, by the car.

Studs

75, 76 are iixed to, and extend inwardly from, the depending

portions

45, 46,

respectively, of the indicator frame 43, the adjacent end portions of which studs are adapted for successive engagement with lower corners of the respective cards 74.

The operation of this device is as follows: Upon the advance of a car along a line, the outer end portions of the reciprocating piston-

rods

24, 25 respectively engage the curvilinear faces of the

brackets

37, 37, and are moved inwardly thereby, thus approximating the piston-

heads

21, 22, and compress the air between said heads within the cylinder 20; such compression of air setting upa current through the pipe 66 into the valve 67, elevating the valve-stem 70, passin g through the aperture in the partition 69 in said valve, out through the port 72; thence along the pipe 66 into the cylinder 63, impacting with the piston-head 64, depressing said piston, oscillating the lever 60, causing the pawl 6l to engage the ratchet-teeth on the plate 58,

and rotatably move said plate; rotating the shaft 5l and heads 56, 57, and bringing into contact with the

studs

75, 76, the next indicating card 74 of the series. Upon the passage of the car beyond the studs 37, first acted upon, the pressure ot' said studs upon the end portions of the

reciprocating rods

24, 25 being released, the springs 32, 33 will, by reason of their resiliency, re-position the said rods and piston-

heads

21, 22 into a normally relative location, preparatory forcontact with the next succeeding lugs 87, and the successive operation. The next succeeding operation of the parts resulting in a rotation of the indicator heads, carries the indicator card, heretofore resting in engagement with the

studs

75, 76, past said studs, and brings the next succeeding indicator card into engagement with said studs.

It will be observed that the visual card, at all times, occupies an inclined position in engagement with the

studs

75, 76, and in position for convenient examination by the passengers, and, upon the passage of the successive cards out of engagement with the studs 7 5, 76, the same assume a depending position, and are hidden from view.

The purpose of the depending rods 65 is, in the event of, the failure of the indicator to automatically operate, the conductor of the car, upon which such indicator so failing to operate is located, may, by the application of manual force to the depending rod, actuate said indicator, and position the same for op- IOO eration at the next succeeding crossing, or

adjacent oneside of the railway-track, and the free end of the other closely adjacent the opposite side of said track, suitable supports for said piston-rods, springs 32 and 33 mounted on said piston-rods and arranged to return said pistons to their normal position at the outer ends of said cylinder, obstructions fixed oppositely along both sides ofv the railway track at determinate distances apart and adapted to be struck by said piston-rods which project over the rails vof the track, whereby both of said pistons will be simultaneously forced inward, or if one be out of order the remaining piston will be forced inward, an indicating apparatus mounted within the car, and a pipe 66 connecting said indicating apparatus with the space between said pistons, substantially as herein specified.

2. In a station indicator, the combination of two opposite depending

portions

45, 46 having bearings, a horizontal shaft 51 mounted in said bearings, opposite disks or heads 56, 57 fixed on said shaft between said depending

portions

45, 46, a plurality of horizontal rods 73 connecting said opposite heads and spaced apart, a plurality of cards 74 marked upon corresponding faces with the names of streets or stations and loosely mounted at one edge, one upon each of said rods, so as to depend therefrom by the action of gravity with the lower edges of said cards free, two studs or pins 75 and 76 projecting oppositely upon the inner faces of said depending

portions

45, 46 in the path of the lower edges of said cards and adapted for successive engagement 3 5 thereby, whereby said cards will be successively tipped face downward as the frame which carries them revolves in a given direction, a friction-brake for holding the card frame in a given position, and mechanism for 4o rotating the frame which carries said cards, substantially as herein specified.

3. In a pneumatically operated station indicator, the combination, of a pneumaticallyoperated indicating-mechanism, a pipe for 45 conveying air to said mechanism, a pump for forcing air into said pipe, a valve interposed in the line of the passage of the air, a transverse partition in said valve having a transverse aperture therein, a plug seated in said 5o aperture and in engagement with a valvestem, and a spring acting upon said valvef stem and normally retaining the same in its seat.

In testimony whereof we affix our signatures 55 in presence of two witnesses.
