SPECIFICATION forming part of Letters Patent No. 367,392, dated August 2, 1887.

Serial No. 193,892. (No model.)

To @ZZ whom it may concern.-

Y Beitknown that we, SANDEOED H. HAEROD and SALEM T. LAME, citizens of the United States, and residents, respectively, of Canton,

5 Washington county, State of Indiana, and New Albany, Floyd county, State of Indiana, have invented certain new and useful Improvements in Station-Indicators, of which'the following is a specification. Our invention relates to that class of indicators usually employed in railway-cars for exhibiting the names of the successive stations upon a shifting band or canvas, Vand ourinvention consists in constructing and arranging the 15 parts of the apparatus, as fully described hereinafter, so as'to secure an extended display of the names, a proper bearing forthe journals of the rollers and drums, preventv the displacement of the latter, and facilitate the construc- 2O tion and manipulation of the apparatus.

In the drawings, Figure lis a front elevation of our improved station-indicator. Fig. 2

is a cross-section, enlarged, on the line 1 2, Fig.

l. Fig. 3 is a verticalsection on the line 3 4, 25 Fig. 2. Fig. 4 is an enlarged section of one end of one of the drums. Figg is a cross-section of one of the clamp-bearings. Fig. 6 is a detached perspective view of the fixed sections of the bearings.

'The apparatus consists, essentially, of the case A, a frame or support, E, above the case, drums or rollers B B, guide-rollers C G, drumoperating handles D D, and a sheet or canvas, l, which is wound upon the drums and passes 3 5 round the guide-rollers. j

In order to make the case A of thin stuff, and at the same time secure the requisite strength, we provide the sides ct a with cleats b b, so arranged that the back c may be inserted within.

4o the sides and rest upon the cleats; and a partition, d, is centrally arranged to support the back, as shown in Fig. 2, and a light frame, J, which may be rabbeted to receive the edges of a front plate, K, of glass, and is secured to A5 the front of the frame, so as to hold the glass in position thereon, and a guide plate or board, L, is arranged parallel to the glass at -a short distance therefrom, to leave a space sufficient for the passage of the canvas without its con- 50 tact with .the face of the glass. The board L is, however, so close to the glass as to effectthin metal, having a central opening for the ually prevent the canvas from wrinkling or creasing, so that the names and other matter upon the canvas will be distinctly presented to those who may inspect the same. 5

In order to secure iirm and immovable bearings for the journals of the rollers, while at the same time using very light material for the construction of the case, We make such bearings of metal. For instance, the upper bear- .6o ings of the drums B and the upper and lower bearings of the guide-rollers consist each of a metallic tube, f, adapted to receive the journal of t-he roller, and an annular dan ge, f arranged externally midway between the ends of the tube and perforated for the passage of screws,

' which secure it to the top orbottom of the case,

the inner end of the tube extending through an opening in said top or bottom. The metallic' tube constitutes a durable and almost friction- 7o less bearing 4for the journal of the roller, while the flange f affords a ready means of securing the bearing to the thin material of which the box is made, and secures such a wide support that the position of the bearing will not be changed by the warping of the wood.

To prevent the canvas from rubbing at its edges against the case, we provide each roller with an end ange, consisting of a disk, g, of

passage of the journal, and secured by screws against the shoulder formed upon the roller by contracting the end portion to form the journal, and to securely fasten the end of the canvas toveach drum or roller we provide the latter with a longitudinal groove, at, in which lits a detachable strip, h, secured by screws and binding the end of the canvas closely in the groove, and having its outer face flush with that of the drum. 9o

In order to secure such a frictionless resistance to the turning of the drums as will prevent the canvas from being loosened by the shaking of the case, We apply friction to the journals of the drums to an extent sufficient to prevent them from working loose, without interfering with their ready rotation when power is applied to the handles or cranks. As one means of securing this friction, and at the same time obtaining a desirable bearing for the journals of the drum, we use a bearing somewhat of the character before described;`

IOO

but the portion f, instead of being tubular, is a semi-tube, f2, as shown in Fig. 6, the other portion, f3, Fig. 5, being a separate piece and having an external flange, e, adapted to a recess, y, formed in the ilangef of the bearing, so that the portion f3, which is curved to tit the side of the journal, may be moved to and from the portionfL under the action of a screw, F, which extends through a hub, o1, formed upon the iangef. A curved section of the flange e extends over the hub n, and aids in guiding the movable section of the bearing. The clamping-bearing thus formed is secured to the casing by screws passing through the tlangef, as bei'ore described, and the journal of the drum extends between the curved sectionsfff, and is clamped with a pressure depending upon the adjustment of the screw F.

It will be evident that the bearing may be constructed in diii'erent ways, with one section movable so as to be clamped against thejournal to vary the frictional resistance to the movement of the drum.

The crank-handles D are arranged upon the lower ends or journals of the drums, so that each can be readily seized when the case is secured in an elevated position to turn either drum to any extent required to bring the matter upon the canvas into proper position for inspection. These crank-handles may be constructed in any suitable manner. I prefer to form each of them with a socket for the reception of the contracted end of the -journal, to which it is secured by means of screws, as best shown in Fig. 4.

By the abovedescribed arrangement the matter upon the canvas may be brought to its desired position and the canvas moved from time to tilneas required. The frame or support E supports a card containing the words The next station,77 and'on the canvas is aspacei'or the names ot' the stations in succession, and a space below for the iigures indicating the distance of the station named from the preceding station. There is alsogenerallyadditional space for one or more lnain stations on the line, and spacebeloweach for the distance to suchstation. Thus, when the canvas is arranged as shown in Fig. l, the name New Albany indicates the name of the next station, and the matter below, Six miles, shows the distance to said Station. The names Louisville and Ohi- \Vithout limiting ourselves tothe precise construction and arrangement of parts shown,

l. In a station -indicalor, the combination ot a easing having sides and ends, cleats secured to the ends, a back secured to said cleats and to the interior surface of said sides and ends, a partition extending within thc easing and dividing the same into two separate compartments, a drum arranged in each ol' said compartments and provided with a longitudinal groove to receive detachable strips, journals on the drums of less diameter than the latter, whereby shoulders are formed, disks secured. to said shoulders, and a belt carrying legends, all substantially as and for the purpose described.

2. In a station indicator, the combination of a casing provided with two separate compartments, a grooved winding-drum located in each oi' said compartments,shoulders formed upon the ends of the drums and constituting journals therefor, disks surrounding and secured to said shoulders, tubularjournalbearings, each having a projecting flange midwa between its ends, and a traveling band, substantially' as and for the purpose described.

3. In a station indicator, the combination of a easing separated by a partition into two compartments, a belt carrying legends,a winding-drum placed in cach ot'said compartments and provided with journals and journal-bearings for said drums, each consisting of a semitubular sectionhavingan annulartlange formed thereon midway between its ends, and a second semitubular section adj nstably supported by said annular ilange, substantially as and for the purpose described.

In testimony whereof we have signed our naines to this specitication in the presence of two subscribing witnesses.
