RAILWAYRAIL-CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 444,675, dated January 13, 1891.

Application filed May 17, 1890. Serial No. 352,184. (No model.)

T0 aZZ whom t may concern:

Be it known that I, JOHN SEROR, acitizen of the United States, residing at Oohoes, county of Albany, and State of New York, have invented certain new and useful Improvements in a RailWay-Rail-Oleaning Machine, of which the following is a specification.

My invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described, and subsequently claimed.

Reference may be had to the accom pauyin g drawings and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

Figure l of the drawings is a bottom plan View of a street-railwaycarwith my improved device for cleaning the railway-rails attached, the middle portion of the car being broken away. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical cross-section of a hanger which supports the slide-bearing of a brushshaft, taken on the broken line 3 3 in Fig. l. Figeisasimilarsection of the double hanger Which supports one end of the cogged-Wheel shafts, taken on the broken line et 4 in Fig. l. Fig. 5 is a centrallongitudinal section of one of the rotary brushes, showing the brushshaft in section, with some of the Wires removed frorn the hub-sleeves. Fig. 6 is a plan View of one of the hub-sleeves with the Wires removed. Fig. 7 is an end view of the sleeve, showing some of the Wires inserted. Fig. 8 is a plan view of one of the Wire staples detached from the hub-sleeve.A

A is the car, which has end platforms A', mounted upon the axles A2, provided with fixed track-wheels A3.

Depending from the bottom of the car or platform are the hangers A4 and Aigwhich support the rotary shaft A, having fixed thereon the cogged wheel A7. Such shaft is connected at each end by a universal joint A8 with one end of a brush-shaft B. The other end of each brush-shaft is provided with a cylindrical brush B', and is supported by a hanger B2, depending from the bottom of the car, in a position such that the brushes extend diagonally across the track-rails, one across one rail and the other across the other rail. The position of the rails is indicated in Fig. l by the dotted lines B3. The dogged wheel A7 engages with the cogged Wheel B4, fixed upon shaft B5. The latter shaft has its bearings in the hangers A4 and BG and is provided With the sprocket-Wheel B7, fixed thereon. The' sprocket Wheel is connected by the sprocket-chain BS With the sprocket-Wheel B9, fixed upon one of the car-axles, which axle has the function of a driving or motor shaft, whereby a rotary movement is communicated from such axle to the brushes, the cogged wheels being interposed to reverse the rotary movement and cause the brush-shafts to rotate in a direction opposite to that of the caraxles and force the obstruct-ions to either side of the track. Then the track is approximately free from obstructions, and the brushes not needed, they can be raised from the rails by means of the levers C, fulcrumed in the hangers C', depending from the bottom of the car, one end C2 of each lever being movably secured to a brush-shaft and the shaft being supported by a slide-bearing B10, movable vertically in the slideway B12 in the hanger B2. The other end O3 of each lever is linked to the hand-lever C, fulcrumed at C5 upon the dashboard AS.

The hand-lever is provided with a stop-latch C, fulcrumed at O7 upon the lever, and controlled by spring C8, adapted to hold the lever in the desired position by means of the nose C, passing through an aperture in the lever and into one of a plurality of apertures formed in the dash-board and adapted to receive it.

That part of the hanger At1 which supports shaft B5 is provided with a horizontally-elongated bearing-slot D, which permits of a sufficient lateral and horizon tal movement of the shaft to Withdraw the cogged Wheel fixed thereon from engagement with the other cogged Wheel. The required lateral movement is imparted to the shaft by means of the rock-shaft D', which is supported by the hangers D2 and provided with the rock-lever D3, linked to the hand-lever, and the rocklever D4, connected bylink D5 with the vibratory end of the shaft B5. The levers C and D3 are connected pivotally with the link D5,

which links them to the hand-lever and brings them Within the convenient control of the cardriver when standing upon the platform. By pushing down upon the handle of the lever the brushes are lifted from the rails, and at the same time the rock-levers disconnect the cogged wheels, leaving the brushes idle, thus saving them from Wear when the condition of the track is such that their use is not required. By raising the hand-lever the brushes are forced down upon the rails and the cogged wheels into engagement. rlhe brushes are preferably formed in sections consisting of a plurality of metallic hub sleeves I-I, each sleeve having its shell provided with numerous perforations H', adapted to receive the Wires forming the brush proper. The wires are preferablyin the form of a staple H2. The prongs are passed through the perforations from the inside of the sleeve, so that the yoke H3 of the staple rests upon the inner surface of the sleeve between the perforations which receive its prongs. The several sleeves, thus provided with any desired number of wires and arranged in any desired known form, are successively slid upon a supporting-shaft H4, adapted to t the interior of the sleeves and bear irmly against the yoke of the Wire staples, thereby securing them in a fixed position.

The brush-shaft is provided witha collar H5, which forms a bearing-stop for the sleeve first slid onto the shaft. The end of thejshaft is screw-threaded,as shown, and after the desired number of sleeves have been placed upon the shaft they are forced into close engagement with each other bya nut H, ttin g the threaded end of the shaft, which is turned up to tightly clamp the sections between the nut and collar. I am thus able to produce a brush made wholly of metal, andv if the brush wears unevenly the sleeve-section having the damaged Wires can be easily removed and a new section inserted, or the relative position of the lsections can be changed from time to time as desired, until all the wires are Worn out.

The slide-bearing B10 is provided with trunnions B13, (indicated by dotted lines in Fig. 1,) adapted to slide and turn in the slidewaygrooves B12 in the hanger B2.

I prefer to make use of one of the car-axles as the motor-shaft for driving the brushes, as

shown; but any known form of motor may be employed.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a railWay-rail-cleaning machine, the combination, With a brush-shaft, of a fixed bearing located near one end of such shaft, a movably-ad j ustable bearing located near the other end, means, substantially as described, for adjustably moving such movable bearing, and gea-r connections between such shaft and a motor-shaft, substantially as described.

2. In a railway-rail-cleaning machine, the combination, with a shaft rotary in fixed bearings` a motor-shaft, and gear connections between such shafts, of a pair of brush-shafts respectively connected at one end by a universal joint to the ends of the driven shaft, movable bearings for the other ends of the brush-shafts, and means, substantially as described, for adjustablv moving the movable ends of the brush-shafts.

5. In a railway-rail-cleaning machine, a shaft rotary in fixed bearings, a cogged Wheel fixed on such shaft, a counter-shaft having a fixed bearing at one end and an adjustable bearing at the other end, a cogged wheel fixed upon the counter-shaft and engageable with the oth er cogged wheel, a sprocket-Wheel fixed upon the counter-shaft, a car-axle, a sprocketwheel fixed upon the axle, and a sprocketchain connecting such sprocket-Wheels, in combination with a brush-shaft connected at one end with the shaft rotary in fixed bearings by a universal joint, a movable bearing which supports the other end of the brush-shaft, an adj Listing-lever mo vably connected at one end with the brush-shaft, a fixed fulcrum located intermediately of the ends of the adjustinglever, a rock-shaft and levers with connections v for connecting one of the rock-levers with the laterally-movable ends of the counter-shaft, a hand-lever fulcrumed upon a fixed support, and a link connection for connecting the handlcver with the brush-adjusting lever and one of the rock-levers, substantially as described.

In testimony whereof I have hereunto set my hand this 13th day of May, 1890.

JOHN SEROR.
