IMPROVEMENT lN CARPET-SWEEPERS.

Specification forming part of Letters Patent No. 125,369, dated April 2, 1872.

To all whom it may concern:

Be it known that we, FREEMAN O. WILLEY and DANIEL B. McENnRY, both of La Fayette, in the county of Tippecanoe and State of Indiana, have invented a new and Improved CarpetDuster 5 and we do hereby declare the followin'g to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure lis a perspective view, partly broken away to show the interior of the case; and Fig. 2 is a transverse section of the case taken in the plane of the line oo x, Fig. 1.

Similar letters of reference in the accompanying drawing indicate the same parts.

Our invention has for its object toy provide for public use an improved carpet -sweeper and duster, which shall be simple and economical in construction, and more efficient in operation than those heretofore in use. To this end the invention consists in the construction and combination of various parts, as we will now proceed to describe. K

In the accompanying drawing, A is the rectangular or quadrangular case ofthe duster, formed with a cylindrical or curved front, and

.having its bottom partly closed by the strip B, so as to leave a narrow opening adjoining the lower edge of the curved front. C is the dust-pan, entering the back of the case and extending nearly or quite to the front edge of the bottom strip B, and resting thereon. D is the handle of the duster, extending at an angle rearward from the top of the case, and provided with a short stud or arm, E, carrying a wheel, F, which is adapted to run on the carpet in rear of the-case, and which also serves to support the machine in an upright position at the proper angle. G is a cylindrical brush, placed within the case immediately over the narrow opening in its bottom, with its ends or journals extending through curved slots h in the ends of the case. I is an adjustable frame or plate, extending longitudinally of the case upon the top thereof, and immediately in front of the handle D, its ends being bent down to receive the journals of the brush, and pivoted at j to the ends of the case. lc is a thumb-screw extending through a lip, l, projecting from the rear edge of the frame I into the handle ofthe machine. By adjusting the thumb-screw the frame is turned on its pivots to raise and lower the brush, so that it shall bear with greater or less force upon the carpet during the operation of sweeping. M is a roller, placed in front of the case to prevent its coming in contact with and rubbing the carpet, and to smooth down the latter in advance of the brush. This roller has its bearings in angular arms a, pivoted to the ends of the case, and is made adjustable, to correspond with the adjustment of the brush, by thumb-screws o, which pass through the ends of the angular arms into slots formed in the ends of the case. Motion is communicated to the brush by means of a belt or cord, P, passing around a grooved pulley, R, afxed to the center of the brush-shaft, thence through a plate, S, attached to the top of the case, and around a large grooved crank-pulley, T, upon the side of the handle near its outer end. The plate S is made adjustable transversely ofthe case by slots and set-screws ato accommodate the movement of the belt when the brush is adjusted, and to dispense with the necessity of a slot, which would allow the dust to escape.

In using the duster the operator seizes the handle D in one hand to guide and push the machine along, while he operates the pulley T to rotate the brush with the other hand. The drivin g-belt is crossed, as shown, to rotate the brush backward, so that the dust shall be taken from the carpet and carried entirely over the brush before it is deposited in the pan. Owing to this arrangement the surplus dust not gathered is swept to the front of the machine to be taken up as the latter proceeds, instead of being swept to the rear and left upon the carpet. By constructing the front of the case cylindrical in form, the ends of the bristles or brooms act against its inner surface to carry up the dust and prevent it from dropping back to the carpet. Owing to the rapid motion of the brush, a strong current of air is induced through the narrow opening in the bottom of the case, which takes up as much dust as the bristles of the brush itself. The action of the 'bristles lifts the nap of the carpet, while the suction of the air picks up all the fine dust and lint, leaving the carpet much brighter and newer in appearance than when swept by other means. The devices for adjusting the brush v and smoothing-roller may be arranged inside as well as outside of the case, if desired, without departing from the principle of our inven tion. Y

Having thus described our invention, what We claim, is-

l. In combination Witli Jche case A and rotary brush R, We claim the adjustable supporting` frame I, substantially as described, for Ialle purposes specied.

2. The adjustable plate S, combined with the ease A and cross-belt P, substantially as described, fer the purposes specified.

3. The roller M, adapted for adjustment at the cylindrical front of the case to correspond with the adjustment of the brush, substantially as described, for the purposes specied.

4. The stud E, carrying the roller F, and affixed to the inclined handle D, in combination with the case A B, as described, for the purposes specified.

5. The carpet-duster, consisting of the roundfronted case A B, the rear dust-pa11,`the inclined handle, the adjustable smoothing-roller M, the brush R, and the devices for operating and adjusting the latter, substantially as described, i'or the purposes specied.
