TRACK-SWEEPING ATTACHMENT FOR STREET-CARS. l

SPECIFICATION forming part of Letters Patent No. 648,685, dated May l, 1900.

Application filed January 3,1900. Serin No. 209. ci@ man To' @ZZ tai/"1,0771, it may concern:

Be it known that I, FRANCIS X. FAUCHER, of thecity and county of lVorcester, in the State of Massachusetts, have invented cer-y tain new and usefulV Improvements in Track- Sweeping Attachments for Street-Cars; and I do hereby declare that the following is a full, clear, and exact description thereof, lref.- erence being had to the accompanying drawf ings, forming a part 0f this specification, and 1 in whichj Figure lis a plan of so much of my Said improved track-sweeping attachment as is necl essary to illustrate myinvention. Fig. 2 is a l front end view of the parts shown in Fig. l looking in the direction of arrow d, sameiigure, part of the brush being shown broken A. away to better illustrate the parts coming back of the same; and Fig. 3 is a side view of the parts shown in Fig. l looking in the direction of arrow b.

In all of said figures only so much of the car to which my attachment is applied is shown as is necessary to illustrate the-application of my invention thereto.

Said invention consists of certain improvements in the construction of mechanismeinployed for supporting the brushes in their: proper positions over the tracks, for rotating said brushes by power transmitted from the car-axle, for adjusting said brushes towardand from said tracks, and for permitting them to yield upward against a yielding pressure when said brushes come in contact with obstructions on the tracks, as will be hereinafter more fully set forth, and pointed out in the claims.

In order that others may better understand the nature and purpose of my said invention, I will now proceed to describe it more in detail.

Referring to the drawings, A represents part of the platform, and B one of the steps, of a street-car.

C is part of one of the axles, and D one of the wheels mounted thereon and which con- Said sweeping attachment, it will be understood, is in practice designed to 'be ap.-

attachment provided with two brushes, one

for each track; but as the mechanism forv ed and fitted to turn in suitable bearings F,

attached to the frame of the car-truck G,

y and in bearings F on stationary hangers F2, and upon said shaft E are mounted the sprocket-wheel H, rclutch I, adapted tobe engaged with the hub thereof, and bevelgears .l J', the sprocket-Wheel being fitted to turn loose on said shaft and the other parts attached to and turning therewith. Said sprocket-Wheel His connected by an endless chain K witha sprocket-wheel L on the caraxle and receives its driving power therefrom. From the shaft E the driving power is transmitted, through the bevel-gear J and bevelgear M, to a short longitudinal shaft N, fitted to turn in suitable stationary bearings N N2,

lmounted, respectively, on the stationary hanger F2, above referred to, and a similar stationary hanger F3, both secured to a frame O, in turn secured to the car-truck G. The bevel-gear M is secured to shaft N, and upon said shaft is also secured the sprocket-wheel P, which is connected by an endless chain Q with another sprocket-wheel R, secured to the inner end of the short longitudinal shaft S, upon whose outer or forward end is mounted and secured the brush T, whose peripheral surface is adapted to lie centrally and longitudinally just above the surface of the track, so that it may sweep the snow therefrom when rotated, as hereinafter described. The said brushshaft Sin mounted and fitted to turn in suitable bearings U U' upon the outer ends of transverse rock-levers V V. Said levers are 'pivoted at a short distance from their inner ends to shaft N and at said inner ends to the outer ends of a short horizontal bar or bearing W, having a central vertical hole and tted over a short vertically-arranged stud W', secured to bearing X4 on rock-shaft X. Said shaft is arranged longitudinally and horizontally and is centrally pivoted tothe lower forked end of stationary bearing X6. Between the inner ends of the IOO levers V Vand the top of bearing X4 is interposed a spiral spring X2, fitted over the stud WV', the purpose of said spring being to force said inner ends of the levers V V' upward against the transverse holding-pin X3V and at the same time permit the levers to be' forced down against said upward yielding pressure of thc spring when the brush T comes in contact with any obstruction, the

inner ends of said levers V V' being fitted to slide up and down on said stud to admit of said vertical movements. The bearing X is provided with two short arms, one at each side of shaft X', just long enough to form a support and bearing for the inner ends of each of the pairof levers V V', as is shown in Fig. 2. The rock-shaft X' has pivoted to its inner c nd a rock-lever X5, in turn pivoted to stationary bearing X. To the outer end of lever is pivoted the lever Y for operating the various parts to adjust the brushes toward and from the tracks. Said lever may be connected with a shipper extended up where it `may be conveniently operated by the motorman on lthe car-platform or in any other suitable manner. For convenience in illustration it is shown in this instance extended to one side of the car and its outer end provided with an adjustable spring locking device Y', consistingof a toothed rack c, se-

cured to the car-truck, with which a toothedv rack d on the lever engages, being held in engagement by a spring e, mounted in a snitable stationary bearing f. The lever is operated longitudinally by raising its outer end against the spring-pressure, and after adjusting it longitudinally to the desired position the spring is allowed to force it black again into engagement with the toothed rack.

By the foregoing construction it is obvious vthat when said lever Yis moved outward'the inner ends of the rock-levers V V are forced up and their outer ends, upon which the brush T is mounted, are forced down toward the track, and vice versa when said lever Y is moved inward toward the car. The brushes, therefore, it will be seen, may be easily adjusted to any desired position in relation to the tracks 0r lifted up out of the way when not required for'use.

In the operation ofthe sweeper it will be apparent that as the brushes are carried forward they will meet with considerable longitudinal resistance in brushing the snow from the tracks, and in order that the parts which support said brushes may be braced against said longitudinal pressure I attach a frame or bumper G' to the truck frame G, against which the inner bearing U' on shaft S' or a boss U2 thereon may impinge to prevent undue back pressure, that might be liable to disarrange said parts.

It will of course be understood l[hat the gear-and-chain connections between the caraxle and brushes is made in practice to rotate said brushes in directions outward from the track-bed, as is indicated by the arrow in Fig.

longitudinally with the tracks, as by a slight modification in the construction of thesupporting and operating parts in practice the brushes may be arranged obliquely or at an angle to the tracks without departing from the principle of my invention.

Power may be `transmitted from the driveshaft E to turn the brush upon the opposite side of the car from ybrush T through' the bevel-gear M' and rock-levers V2 V2, which connect with similar mechanism to that shown in the drawings, as previously described.

Any suitable and convenient mechanism may be employed for engaging and disengaging the sprocket-wheel II to and from the drive-shaft E. In thisinstance I have shown theouter side of the hub of said sprocketwheel'provided with notches, with which the clutch I, fitted to turn with shaftE, is adapted to engage. Said clutch is moved into and out ofen gagement therewith by means of a shipper Z, fitted to slide longitudinallyin stationary bearings and pivoted at its inner end to a short lever Z', centrally pivoted to a stationary bearing and whose inner end is pivoted to the hub of clutch I.

I-Iaving now described my invention, what I claim therein as new, and desire to secure by Letters Patent, is-

l. A track-'sweeping attachment, comprising in combination a transverse, horizontal shaft E fitted to turn in suitable4 stationary bearings and driven by connection with the car axle or wheel, a clutch I and means for operating it, for shipping and unshipping the driving power to and from said transverse shaft; a short longitudinal shaft N supported in suitable bearings yand having means for transmitting' the driving power of shaft E thereto; transverse rock-shafts V V pivoted ata short distance from their inner ends to said shaft N, and at said inner ends to a bearing fitted to slide on a stud mounted on bearing X4, and having means for controlling the upward movements of said inner ends of levers V V'; the short longitudinal shaft S fitted to turn in the outer ends of said levers V V', and having the brush T mounted thereon; means for transmitting thedriving power of shaft N to shaft S; spring X2 for imparting an upward yielding pressure against the inner ends of levers V V', rock-shaft X' pivoted to a stationary bearing; rock-lever XG pivoted to a stationary bearing and to rockshaft X', and means connected with and for operati-ng lever X5 to adjust the brush T up or down, substantially vas set forth.
