BENSON W. JOHNSON, OF PROVIDENCE, RHODE ISLAND.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 228,358, dated June 1, 1880.

` Application led September 26, 1879.

To all whom it may concern Be it known that I, BENSON W. JOHNSON, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Carpet-Sweepers; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

Figure l is a perspective view of my irnproved carpet-sweeper. Fig. 2 is a sectional view, showing the construction of the adjustable handle. Fig. 3 is a sectional view of the carpet-sweeper, showing the roller for driving the brush, the construction of the dust-pans, the construction of the cover, and the manner of securing the brush. Fig. 4 is a view of the drivin g-roller. Fig.5 is a sectional view, showing the end of the brush and the driving-roller. Fig. 6 shows a modification of the drivin g-roller.

Thisinventionhasreferencetoimprovements in the construction of the oarpet-sweeper.

rIhe object of this invention is to simplify the construction and increase the durability of a carpet-sweeper.

It consists in the details of construction hereinafter specied and claimed.

In the drawings, A is the box proper, within which the brush revolves. It is made with rounded corners and curved ends, so as to prevent injury to the furniture.' B is the cover of the box, made of sheet metal and strengthened by bending the edges b and b and doubling the metal, so that a strip of leather, cloth, or other iiexible material can be secured at the edgeb andform, when secured to the box, the hinge for the cover. The latch is secured in the same manner at b by being inserted between the doubled metal forming the edge of the cover.

The cover is made sti' and rigid by the doubling of the sheet metal along the sides, while the ends lie closely on the curved ends ofthe box, thus making a tight joint at all points between the cover and the box, and producing a lighter, more durable, and less costly curved cover than was heretofore possible.

C C are two dust-pans, made of tin or other sheet metal. To secure a dust-tight joint for these dust-pans I extend the ends c of the sheet metal and nail the bottom to the ends of the box, as shown in Fig. 3.

d is a revolvin gbrush provided with the axles @,one on each end. These axles run in fixed bearings on each end of the box, and to facilitate the insertion or removal of the brush the cylinder of the brush is made shorter than the box, the slidef is raised, the axle inserted at this end rst, and the opposite axle is brought on a line with its bearing. The brush is now moved laterally and the slidef pushed down. The brush is held by the slide f and lateral play prevented.

The ends of the brush-cylinder are provided with rubber or other elastic rings, and under each end of the brush-cylinder a roller, g, also covered with rubber, is placed, which rollers g g drive the brush by contact with the cylinder ol. The bearings of these rollers gg are arranged so that the weight of the apparatus rests on the two rollers and brings them into close frictional contact with the portion of the brushcylinder covered with rubber. In Figs. .tand 5 the roller g is shown provided with a hole larger than the pin, so that the roll can be pressed against the brush-cylinder. The roller g may be hung in a hinged frame, as is shown in Fig. 6, and the same result obtained.

h is the handle by means of which the carpet-sweeper is operated. This handle is secured to the box by means ofthe curved bracket t', provided with a slot, and the nut h4,the bearing-surface of which ts the inner surface of the bracket L'. rThe handle h is provided with a threaded pin, h3, which screws into the nut.

The improvement consists in a washer, h2, :fitting the curved bracket, and an elastic washer, It', interposed between the end of the handle and the washer h2. By this arrangement the handle can be more easily turned, and when fastened the handle holds more firmly, as the curved washer gives a wider bearing on the bracket than was possible with the end ofthe handle.

In Patent No. 194,095, dated August 14, 1877, the handle is adjustably confined to a bracket by a nut and without washers. In hoes it is old to secure the blade at various angles upon the slotted tang of the handle, and to use in these adjustments a plano-convex and a plano-concave washer, presumably of inelastic material, arranged upon opposite sides of the curved tang.

IOO

I am not aware that the curved washer h2 and the elastic washer h have ever before been used as herein shown nud described.

Having thus described my invention, I claim as new land desire to secure by Letters Pntent- 1. In ecarpet-sweepe1",tl1e combinntiomwith the box, ofaslieet-metal Cover the sides ofwhieh lare stifened by doubling' the nietzthund which is secured to the box by e liexible materiel secured between the bent und doubled edge, substantially as described.

2. A movable handle having a screw end secured by a nut within a slotted bracket, in combination with a curved wash er, h2, bearing I 5 upon seid bracket, mid nn elastic washer, h', interposed between Said Curved washer and the end of the handle, whereby the handle may be more easily turned nud more securely fastened in place, owing to the enlarged benringzo snr-thee, substantially as shown.
