CARPET- PATENT OFFICEO OF GOSHEN, INDIANA.

SWEE'PER.

` SPECIFICATION forming part of Letters Patent; 1\To.367,528l dated August 2, 1887.

Application filed March 2G, 1886. Serial No. 196,612. (No model.)

To @ZZ whom, t may concern:

Beit known that I, GEORGE 1V. KELLEY, a citizen of the United States,`residing at Goshen, in the county of Elkhart, State of Indiana, have invented certain new and useful Improvements in Carpet-Sweepers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to carpet-sweepers, and has for its object to simpliiythe construction, reduce the cost of manufacture, permit of the insertion and removal of the brushshaft, and to provide means for the attachment and detachment and retention in a desired position of the handle, and to accomplish these ends by a minimum of hand labor in connection with the manufacture.

Other objects and advantages of the invention will appear in the following description, and the novel features will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a bottom plan view of a sweeper constructed in accordance with my invention. Fig. 2 is a vertical transverse section on the line as of Fig. 1. Fig. 3 is a vertical section on the line x of Fig. 2. Fig. 4 is an end elevation, and Fig. 5 a plan, of the handle bearing. Fig. 6 is a een` tral longitudinal section of the same. Fig. 7 is an end elevation showing the handle elevated. Fig. 8 is a plan of the bearing with the handle removed. Fig. 9 is a perspective of a detail hereinafter described.

Like letters of reference indicate like parts in all the gures of the drawings.

A represents the ease of the sweeper, which is provided with the usual dust boxes, A, which in this instance are provided at their ends with doors A2, hinged, as at A3andprovided with a spring-clasp, A4, adapted to take into a recess, `A, formed in the case, (see Fig. 4,) so as to retain the door in a closed position, and yet permit of its being opened for the delivery of the dust from the boxes, or other suitable fastening devices may be used, as desired. A flange, A, (see Fig. 1,) is formed on each of the doors to overlap the joint between it and the adjacent edge of the bottom of tlie dust-box. By this construction dust and dirt is delivered from the boxes more directly, conipletely, and neatly than where the whole of the box bottom or top ofthe ease thereover is opened for such purposes.

Between the end AT of the case A and the dust-boxes there is arranged the usual partition, AS, which forms the chamber for the usual driving mechanism. The driving mechanism comprises rubber-tired wheels B B, each of which is mounted upon a shaft, B', projecting from a slidingfblock, B2, iianged, as at B3, to it a frame, C, secured to the inner surface of the end A of the case. VThe block B'l and the shaft B thereof are yieldingly retained in a position to cause the driver B to bear upon the friction-wheel D ofthe brush-shaft D by means of a rubber band, B, secured at one end to the block and at the other end to a screw or pin, B, projecting from the end Al, said screw or pin also acting as a stop to limit the movement of the block in one direction. Either one or both of the drivers B may be thus mounted, so that the brush-shaft D and the pinion thereon maybe passed between the drivers for the purpose of removing the brush from the case.

If desired, a coiled spring (sec dotted lines, Fig. 2) maybe inserted between the end of the block and cross-bar of the frame C to serve the function of the rubber spring B4. The dotted circle Y, Fig. 2, represents the frictionwheel D of the brush-shafaand the dotted lines Y represent the relative positions of the driving-wheels B when in. contact with the wheel D, when in the act of removing the brush-shaft, the drivers B, their shafts, and shaft blocks being forced apart.

E represents the bearing-block for the journal ofthe brush-shaft at that end thereof which carries the friction-wheel D. Said block is secured to or formed as a part of a spring, E', adjustably secured to the outer surface of the end of the case by screws E passing through slots` in said spring. The lower end of the block. is cut away,l as at E, to form a groove to lead the journal into the bearing E2 formed in the block. The end wall, A7, is also grooved, as at A", for the passage of said journal upwardly into the block, Vwhich yields when the journal enters the groove E* and returns to position when the journal enters the bearing. By reason of the adjustabilityof the spring E the brush-roll may be elevated to adapt the IOC brush to diii'erent kinds of surfaces or carpet. The oppositeend, A1", of the ease has formed therein recesses A11 for the reception of the rollers F, which support the ease slightly above the iloor.

G represents a casting secured to the end A10 of the case and provided with arms G', having journals G2, upon which the Wheels F are mounted.

By the construction just described it will be seen that the wheels F are arranged wholly within the end walls, and that therefore the sweeper and its brush may be brought into close contact with the walls oi' the room.

H represents a casting which is secured to the top of the box or easing, and is constructed. with a recess, H', in which is arranged a spring, H2. The top-of the casting is provided with a turn-buckle, I, pivotally secured by a screw or bolt, l.v Apertu'res H are formed at each end of the casting, for a purpose hereinafter speeilied.

J represents a bail having a tang, J, to which a handle maybe secured in any suitable manner. The bail J is provided with lugs J2, adapted to pass through openings H", (see Fig. 8,) formed in the top of the casting and communicating with the recess H thereof, and to come into Contact with the ends of the spring Hl within the recess, which spring is so formed as to exert an upward pressure upon the lugs J2, so as to force them out of the easti ving and into recesses I in the under surface of turn-buekle,holdingit in position and preventing rattling. In order to retain the lugs, bail, and handle in connection with the casting, the turnbuekle I is swung upon its pivot until its ends rest over the lugs J2. The bail J is extended beyond the lugs J2, as at J, so that when the handle is elevated to assume an upright or nearly upright position with relation In order to allow for variation in length of 5o ease, I have provided at one or both ends of the same a screw-threaded pintle, D2.

Having thus fully described my invention and its operation, what I claim, and desire to secure by Letters Patent, is-

l. In a carpet-sweeper, a handle provided with lugs, in combination with a recessed casting provided with a spring and with a turnbuckle, substantially as speeiied.

2. As a means for attaching` a handle to a carpet-sweeper, a recessed casting, a spring arranged therein, and a turn-buckle mounted thereon, substantially as specified.

3. The combination, with the ease A, of the frame C, the sliding` block B2, carrying the exterior stub, shaft B', projecting from one side thereof, and the spring B* and 'stop of the driver I3, substantially as specified.

4. The eombination,with the case A, having the recess A5, of the dust-box A, having the hinged portion A2, provided with the catch A, substantially as speeicd.

5. The combination ofthe casting H, having the recess II, apertures H:3 H", the spring H2, the handle or bail J, provided with the lugs J2, and extensions J3, substantially as speeiiied.

In testimony whereof I ai'iix my signature in presence of two witnesses.

GEORGE XV. KELLEY.
