UNITED STATES PATENT OFFICE,
ALEXANDER W. STEWART, OF BOSTON, ASSIGNOR TO JOHN J. HALEY, OF NEWTON, AND HENRY O. MORSE, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN CARPET-SWEEPERS.
Specification forming part of Letters Patent No. 186,894, dated J anuary 30, 1877; application filed June 27, 1874.
To all whom it may concern:
Be it known that l, ALEXANDER W. STEW- ART, of Boston, Massachusetts, have invented certain Improvements in Carpet-Sweepers, of which the following is a specification This invention relates to that class of carpet-sweepers in which the brush may be readily removed from the ease for the purpose of clearing the bearings, which is the object of my improvements.
My invention consists in the combination, with the sweeper-frame and an axiallyperforated brush-shaft, of a spindle moving longitudinally Within the brush-shaft, and operated by a spring for protruding the spindle, or a pin for retracting it.
In the drawing, A represents the spindle; B, the brush-shaft, and O the case, or the end board of the frame. The brush is driven by any suitable means, and revolves in bearings provided in, or attached to, the case 0. The spindle may be, at one end of the shaft,ofordinary construction but at the other end (shown in the drawing) it is adapted to move longitudinally within an axial perforation of the brush-shaft, so that it may be protruded to enter the bearing in the frame for use, or retracted to release it therefrom when itis desired to remove the brush from the case. As a means of protruding the spindle I place a suitable spring, a, within the perforation of the shaft B before inserting the spindle therein. This insures such prominence to the projecting end of the spindle as shall keep it in proper engagement with its bearing in the frame 0. The spindle may be conveniently retracted, in order to disengage it from itsbearing, by means of the pin 1), which projects through a slot in the brush-shaft, and by which the spindle A may be moved to right or left independent of the spring a.
For convenience in inserting the brush the case may be provided with guides, serving to direct the spindle into its proper bearing.
The sweeper is furnished with a dust-pan at each side of the brush, and with drivingwheels, cover, and handle, in the usual manner.
I claim as my invention In combination with the frame of a carpetsweeper and the brush-shaft the spindle A, adapted to move longitudinally in an axial perforation of the brush-shaft, and operated by the spring a or the pin 1), substantially as and for the purpose set forth.
