In the drawingslike characters of reference indicate corresponding parts in the several figures.

The box or casing 1 containing the belts and parts associated therewith is substantially rectangular and is preferably formed from sheet. metal and has both the front and rear sidesthereof closed by rectangular frames 3 and 4.- fastened thereto by screws 5 and containing transparent plates 6 and 7 such as of,

13 and the bearing sleeves 14: of the brackets 10 and 12 are vertically aligned as are those bearings 14 of the brackets 11 and 13. Centrally to the rear of the box, we permanently'secure also similar upper and lower bearing brackets 16 and 17 which have their inner ends forked to provide receiving bearings 18, the upper bearing 18 being axially w three a PM a u i. are

aligned with the upper bearing sleeves 15 and the lower bearing 18 being axially aligned with the lower bearing sleeves 15.

It will be apparent that we have six bearand such bearings are utilized to rotatab y siiii and lower pairs of shafts 19-and ,the inner ends of the shafts "being carried w w bearings 15. The outer endsof the an all reduced as indicated at 21 to enter the bearingsla and the inner ends of the shafts are retained within the bearings 18 by cotter pins 22. On the shafts, we mount rotatably upper and lower pairs of rollers 23 and 24,' these "rollers being formed'from opppsing end heads 25 an 26 connected togetherfby atube or pi 2 of predetermined l The pairs o'f i'ollers carry belts 28 an 29. I

In pr der 'to. fasten the ends of the belts to marc er or windin drums in a simple and efl'hctive'manner, we ave provided the ends of the belts with hems 30 and have passed a retaining rod 31 into each hem. The tubes 27 y are longitudjnall slotted as indicated at 32 to'peimit the end of the belts to pass therethrough but the width of the slot in each instance is less than the diameter of the rod so that the rod cannot pull out tlllfOlV'll the slot. u In order to enter the rods, we holes 33 in the inner heads of the winding drums. When the belts are to be fastened to the drums, the hemmed ends thereof are passed through the slots and brought into '3q a position aligned with the holes33. One

then asses the rods through the holes and into t e'hem, the rod being pushed in until it is free of the head at which time, it will drp d Wu and serve as an anchor retaining au the] efil from withdrawing through the slot. To 1 e outer heads of the drums, we secure by screws bevel pinions 34 and these pinions of the'upper and lower drums are cont nuousl in mesh with upper and lower 45 bevelgears 35 and 36 mounted on similar vertical'ly disposed winding shafts 37 and38. Each ofthe latter shafts has its upper end contracted to ,provido a shoulder 39 and a spindle 40 thereabove, the spindle 40 being rotatably received in the up per boa ring sleeves 14 and also carrying rotatably the upper gear @wheel 35 which is supported b the shoulder 39. A cross pin 41 passes through the upper end of the spindle and a wearing up er end of the upper sleeve 14. t 1s holding t shaft a roast we we I a x are nclo ed within pipes or tubes 43 and swlgnpe f lpgmg their ppe ends screw ree, pm, $5 45 fast ed-t0 the 1. a 5! a Q 5 p a e 9. and hen lo er ends gd orecelvea bearing lee've 4,6.

by the bearings 18 and the outerends' have made w er 42 is placed between the in and the The lower end of each shaft 37 or 38 as the case may be passes rotatably through the bearing sleeve 46 and has fastened thereto the head 47 of a crank 48 which is provided with ahand rip 49. A jam screw 5O fastens the head ltifi crank to the shaft.

e under face of the bearing sleeve is provided-with a plurality of equi-spaced semicircular poekets 51 and there isprofembiy an dd number of th s p c e T e uppe f e of the head 47 is drill d to provide two d1- ametrically opposite pockets 52 and 53 which .nceirzesprings 54 and catches 55 in the form of balls. The upper ends of the drilled pockets 52 and 53 are struck in to prevent the balls from escaping from the pockets but it will here be observed that there is suflicient of the ball permitted to protrude from the pocket funde'rthe ressure of the spring to form a depressib e catch engageable wi h one or other of the pockets 51.

By having the balls 55 diametrically opposite and an odd number of pockets 51, we obtain a relatively line adhstment of the head 47in regard to the sleeve 46, as one ball will enter one of the pockets to preventundesired rotation of the head 47 and the h rbe l w ll be iding th lac of he sle ve 46' between the pockets thereof. Obviously the tui'ningipf the crank i mitrols the rotat on of the'shaft 37 or 38 as the case may he and the shaft will be i'eleasably locked in any defllGCLpositimr by theentrance of one or otherof the ballsin one or other of the pockets 51.

The gear wheels 3.6 liereinbefore mentioned are both perinanentl fastened by pins 56 to the shafts 37 an 38 so that the lower w nding drums are: ositiyely driven by the sh afts. The upper evelgears 35, however, are rotatably mounted on the spindles of the shafts and the only driving connection b tween the shafts and the upper bevel gears is by way of. coiled springs and 58 mounted on the shafts and having their lo er ends permanently fastened at 59 to the Shafts and their upper ends permanently fastened at 60 to the upper bevel gears 35.

These springs turn the bevel gears 35when the shafts are turned and serve to compensate for the gradual variation in the d gn eters of the winding and unwinding ends of the belts as will be re dily understood,-

The belts are Pr v ded throu heat than length with the numbers 0123456 89 a aping in arithmetical progression thro qiul th h a th 8f the has, the-auruber% placed thereon in any suitable manner. 3 11nd a: desirab to hav the belts mad rom a l k flexi e a d W p r g thereon an whi e so that the. is a siiarp contrast. The belts are made p c-M y ia v ples t0 he glass; wind w '7' through which the numbers thereon he clearly a and in this osmium m might point out that when the device is in use, only one number on each belt should be seen at one time. In Figure 1, we have shown in dotted outline the numbers 38 as appean ing through the window 7 and these numbers indicate the route number 38.

The inner edges of the belts are guarded by a vertical strip 61 which can be also painted black and this strip carries a centrally located vertically disposed plate 62 which extends vertically between the bearings 18 and is utilized to carry similar pointed indicators 63 and 64. The indicators are both fastened by a bolt 65 to the plate, the bolt passing through a suitable hole provided in the plate and elongated slots 66 in the bases of the indicators. This arrangement allows either of the indicators to be adjusted vertically in respect to the adjacent belt. The belts are both provided at their inner edges and on their rear faces with stopmarks 67 selectively positioned in respect to the adjacent belt numbers. e have considered it desirable to use small numbers on the belts as stop numbers, the small number corresponding in each instance to' the adjoining large number.

7 In orderthat the motorman or other operator may be able to properly set the annunciator without leaving the car vestibule, we have provided a transparent peep opening 68 in the roof of the car throughwhich the motorman can see the indicating pointers and the stop marks and obviously if he wants to set the belts to indicate the route number 38,

he will turn the respective belts until he sees the small stop numbers 38 positioned opposite the pointers at which timevhe knows that the route number is properly positioned in respect to the window 7.

In placing this device on say the front end of a street car vestibule, a substantiallv rectangular hole 69 is cut in the roof of the vestibule and this hole permits the box to be passed upwardly therethrough until the projecting ends of the plate 8 strike the under side of the roof. The roof carries bolts 7 0 and 71 which are adapted to pass into the bolt openings 9 of the plate and the whole device is held in place by winged nuts 73'screwed up against the ends of the plate. This arrangement makes it very convenient not only to put the device in place but also to dis mount it'from the car at any time. The cranks 48 and 49 vare located within convenient range of the motorman and the whole arrangement is such that he does not require to leave his usual position in the vestibule in order to see and set the belts.

The glass plates 6 and 7 forming the windows are'held between resilient strips 74 and 7 5 so that there will be no rattling and such that thejinterior of the casing Wlll be dust aroof and weather proof.
