Definitions

  • Thepresent invention relates to a device applicable to sweepingimachines and formed by one or more auxiliary brushes which among other uses can be employed for sweeping road gutters or along houses.
  • the new device is essentially characterized by the feature that the auxiliary brushes are mounted upon horizontal spindleseach carried by an arm pivoted to the frame of. the a vehicle by means of a cross-shaped joint which makes itpossible to setthe axisof the auxiliary brush in a horizontal plane with a view to passing from a position of rest into a working position, and vice versa, while the horizontal axis of the cross-shaped joint permitsthe brush to. lift automatically when it meets an obstacle,'-and permits the auxiliary brush. to be lifted'by, hand ormechanically for passing from 'a 'working position into a' position of rest, and vice versa.
  • the invention comprises an elastic or compressible element arranged in the transmission actuating each ofthe auxiliary brushes; this element permits the brush to move automatically out of the way in a horizontal direction when it meets an accidental obstacle or strikes against apavement when the vehicle isnot correctly guided, and it also permits the brush to be withdrawn into. a position of restand locked on the chassis of the vehicle.
  • the invention comprises. other practical details of construction which will be described hereinafter.
  • M j H Figures 1 and la form a partial plan view ofthe frame of a sweeping machine of known type, and shows an auxiliary brush according to the present. invention fitted to this type of vehicle.
  • the automatic brush has been shown as being actuated by a transmission driven from the driving, shaft of the main brush, which shaft is assumed tobe perpendicular to the longitudinal axialplane of V the vehicle.
  • Figure. 2 is a corresponding longitudinal elevation of a part.
  • FigureB is a longitudinal sectional elevation showing a. practicalformof construction I of the auxiliary brush.
  • 1 isthe fraine of the vehicle
  • 2 is the driving'forefcarriage
  • 3 is a casingin' which. is situated the shaft 4 for actuating the main brush and which'will provide the power .for driving the auxiliary brush or brushes.
  • 1 1 Y Figures 4 and 5 shows plan elevation respectively, partial view of a modification of the device for preventing-any direct impact between the shaft of the auxiliary brushand an obstacle such as the edge of a pavement, I
  • Each ofthese brushes is mounted upon a horizontal shaft, a and-this shaft is carried by an arm I; connected tov the frame of the vehicle by means of a cross-shaped pivotal joint 0 d .comprisinga vertical axis 0 and a horizontal axis at, By a movement aboutithe vertical axis 0, the arm I) and consequently the shaft a and'the'brush 6 carried by the latter can be made to pass from aipositionof rest into a working position. 1 At the same time this axisipermits the brush to move automatically outiof the way-of it encounters a lateral obstacle when in use, the brush being returned into the normal working position by the provisionofan elastic member in the brush.
  • the brush normallyoccupies the position. shown in. full lines in. Figures 1 and 2. It may be withdrawn into a position of rest by movement about the cruciform joint '0'cZ and'be secured in In order to prevent any direct impact be-- tween the shaft of the auxiliary brush and an obstacle such as a pavement edge or the side of a wall etc., during the work, a disc 9 is fitted or screwed on the outer end of this shaft, upon which disc is loosely mounted a buffer ring 9 The free rotation of the ring 9 thus efficiently damps the impact which would otherwise be transmitted directly to the brush shaft.
  • a brush element of suitable width and having, as shown in Figure 3, a larger diameter than the body of the brush.
  • This increase in diameter may be obtained as in the example shown in Figure 3, by tufts of greater length. It may also be obtained by keeping the length of'the tufts uniform and in case giving the support 6 a suitable pro-
  • a brush element having the desired greater diameter may be fitted to the end of the support carrying a body having tufts of smaller diameter.
  • a shock absorbing roller or disc or any other similar member s is mounted on an arm t adjustable in position on the arm 6 which supports the shaft of the auxiliary brush.
  • the spindle s of the roller 8 is carried by a bracket 8 which may be given a varying inclination with respect to a supporting base 25 formed at the end of the arm t; Bolts 8 movable in slots t in the base t permit the bracket to be locked in the chosen position of adjustment.
  • the height at which the roller '8 is placed may also be regulated;
  • the arm't as shown in Figure 5, carries at its upper enda boss or head i which can be locked in various positions by adjusting bolts 25 carried by the said boss in slots 12 and a yoke 12 itself movable upon an arm I).
  • the device described permits three adjustments to be made by the displacement of the supporting yoke b on the arm 6, the displacement of the arm 27 on the yoke b in a vertical direction and the varying inclinations of the base .9 with respect to the yoke t.
  • the constructional details of the shock absorbing member, adjustable in position, and of its support may vary.
  • an elastic suspension may be provided for the pivot s of the bracket 8.
  • a street sweeping machine having a vehicular frame and a source of power mounted thereon, a supporting arm having journalled in one extremity thereof a substantially. horizontal shaft, a brush mounted on said shaft, a cruciform pivotal coupling connecting the other extremity of said arm to said vehicular frame whereby said arm is capable of movement in both a horizontal and a vertical plane, and means for driving said brush shaft from saidsource of power including a main drive shaft extendingtransversely of said frame, an auxiliary drive shaft parallel to said main drive shaft and operatively connected thereto, 'and a telescoping transmission shaft operatively connected to said auxiliary drive shaft and to the shaft of said brush by universal joints, said transmission shaft having means normally tending to elongate it to urge said brush shaft and brush outward from said vehicular frame to sweeping position and also permitting inward move- .ment of said brush out of the way of obstacles and to inoperative position without affecting the drive thereof.
  • a street sweeping machine having a vehicular frame and a source of power mounted thereon, an L-shaped supporting arm having journalled in one extremity thereof a substantially horizontal brush shaft, a brush mounted on said shaft, a cruciform pivotal coupling connecting the other extremity of said arm to said vehicular frame whereby said arm is capable of movement in both a horizontal and a vertical plane, means for driving said brush shaft from said source of power including a telescoping transmission shaft having resilient means interposed between the telescoping portions whereby the, brush shaft and brush are normally urged outward to sweeping position and the driving transmission is maintained regardless of the movement ofsaid brush shaft relative to said source of'power, and a supporting bracket swivelly mounted on said frame in position to engage and support said arm when the latter is moved inward and upward to place said brush in inoperative position.
  • a brush In a street sweeping machine, a brush, a shaft on which said brush is mounted, one end of said shaft projecting outwardly beyond the brush-in position whereit may encounter obstacles during the sweeping operation, and means for preventing injury to said I shaft by contact with said obstacles comprising a disc rigidly secured to the outer end of said shaft, and a bufi'er ring rotatably mounted on the periphery of said disc.
  • a brush In a street sweeping machine, a brush, a shaft on which said brush is mounted, one end of said shaft projecting outwardly beyond the brush in position where it may encounter obstacles during the sweeping op-v eration, a supporting arm in one extremity of which said brush shaft is journalled, the other extremity of said arm being connected to the body of said machine, and means for preventing injury to said brush shaft by contact with said obstacles comprising a substantially Vertical roller carrying arm, a clamp for adjustably securing said arm to said supporting arm at a variable horizontal distance from said brush shaft, means for varying the vertical position of said roller carrying arm with respect to said clamp, a supporting yoke formed at the lower end of said roller carrying arm, a bracket, a shock absorbing roller rotatably mounted on said bracket, and means for securing said bracket to said yoke in a plurality of angular positions whereby V the inclination of the axis of rotation of said roller may be varied.
