SEJECIFJECATION forming part of Letters APatent No. 695,434, dated March 18, 1902.
Application filed June 10, 1901.
To all whom t 71u03/ concern:
Be it known that I, THOMAS H. BEDELL, a citizene of the United States, residing at Marion, in the county of Grant and State of Indiana, have invented a certain new and useful Improvement in Roller-Bearings for Carpet- SWeepers, of which the following is a specification.
My invention relates to antifriction-bearings particularly intended for use in connection with carpet-sweepers.
In carpet-sweepers there is from time to -time an effective bearing action between the easy replacement of broken parts for adjust- 25 ment.
I have illustrated this bearing in its use in connection with carpetsweepers.
Figure lis an end Viewof a carpet-sweeper. Fig. 2 is a longitudinal section Online -2 2, Fig. l. Fig. 3 is a cross-section through the spindle at one end of the hub.
Like parts are indicated by the same letter in all the igures.
A is the handle of thecarpet-sweeper; B, the box or cover; C C, the wheels; D, the brush-roller; E, the end frame-piece on which the axles F F are journaled.
O is an end band or strip, which is preferably of spring metal and is in the same hori- 'zontal plane as the axles.
Each wheel C is provided with 'ahub C', which is hollowed out at C2 to form a raceway between the inner surface of such holloWed part' of the hub and the outer surface of the end of t-he axle.
The axle F is formed with a projecting spindie in the usual manner, leaving a shoulder at Gto receive the end yof the hub C. In this annular space, snugly fitting all the way around, are placed a series of short, prefer- Serial No. 63,987.- (No model.)
ably steel, rollers I-I H.4 The rollers are preferably of the same length as the hub; but the dspindle is somewhatlonger, and about the outer end of the spindle is placed the loose collar or washer J, which is annular in shape,
its-inner diameter being the same as that of the spindle to receive the spindle and its outer diameter being the same as the outer diame-` ter of the hub to cover the end o'fthe hub and the ends of the rollers. By thus arranging the parts the rollers are free to travelv a similar crushing'strain to be applied to theA rollers for the moment interposed between the axis of the Wheel andthe axis of the brushroller. The action of4 the pressure applied at the handle to push the carpet-sweeper forward affects to acertainl extent this lastnamed tendency. y,
The annular collar or piece J is tightly fitted and may be of any desired material te serve as a dust-proof connection, and asimilar aunular Washer J may be placed at the shoulder G, thus putting the rollers in a dustproof raceway, where they Work at all times and in all positions and travel eachabout itns own axis and all in a progression about the axle.' The parts are all thus held together by means of the end piece O, preferably of spring metal, as indicated.
1t will be seen that by such a construction the several parts of the bearing can be made of the simplest possible form. The hub canbe bored out, the shoulders formed in any simple manner, the'rollers be made from or dinary wire, the annular collar be composed of any suitable material, and all the partsv can be assembled together without the'slightyest difculty, and they are securely held in position by the end of the sweeper or springbar 'preferably employed for that purpose.
IOO
The removal of such bar instantly lays bare all the parts, so that they can be removed an others supplied at Will.
I claim- In a roller-bearing for carpet-sweepers, the combination of an axle having a shoulder and a projecting spindle, with a Wheel having a hub adapted to bear against the shoulder on the axle, but shorter than the spindle, a series of rollers in the raoeway between the hub and the spindle, an exterior Washer covering the end of the raeeway in which the rollers lie and tightly encircling the spindle, a second washer on the spindle between the shoulder of the axle and the end of the hub and rollers, t5
