CARPET-SWEEPER.

SPECIFICATION forming vpart of Letters Patent No. 259,069, dated June 6, 1882.

Application Inca January *1, 1882. (Model.)

To all whom 'it may concern Be it known that I, HENRY S. WING, of Ashtabula, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Garpet-Sweepers; and I do hereby 4declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in 'carpet-sweepers, the object being to simplify and improve the construction and operation of these devices, and to provide a sweeper of such construction that it may be manufactured. at small cost and be durable in use.

With these ends in view the invention consists in combining with the end pieces and pans of a carpet-sweeper a slotted bell-crank lever for dumping said pans.

The invention further consists in the combination, with the friction-rollers and brush of a sweeper, of devices of the improved construction' hereinafter described for supporting and adjusting said brush.

The invention further consists in the parts and combinations of parts, hereinafter fully described, whereby the pans of the sweepermay be tilted or dumped and forced back in operative position by the weight and pressure ap-l plied to the sweeper.

The invention further consists of the details of construction hereinafter fully described, and pointed out in the claims.

In the accompanyingdrawings, Figurel represents a perspective view of asweeper constructed in accordance with my invention. Fig. '2 is a central vertical section of Fig. 1. Figs. 3 and 4 represent parts in detail.` Fig. 5 is a longitudinal section, and Fig. 6 is a modication. end of the sweeper to illustrate. the stud or journal projecting from the pan. .Y

A represents the casing ot' the sweeper, having end pieces,.B B, between which are pivoted the tilting pans C by pivots' c. These pansvare each constructed at one end with an inwardly-projecting ear or arm, c', each provid'edwith an inwardly projecting stud, c2 and c3.

following-described means. brush-roller is provided with a stud, h, while lthe opposite end has an annular recess, h', a

D represents a bell-crank lever, pivoted to the inner side'of the end B ofthe casing by a pivot, b. The lower end of this lever is formed with a diagonal slot, b', adapted to receive the stud c2 of the pan C. A horizontal slot, b2, is

formed inthe opposite end of the lower arm of the lever to receive the stud c3 ot' the other pan, G. The upper end of the lever projects through a slot, not the casing, and is adapted to register with notches e formed in the end ot' the top brace, E, of the casing. The under sides ofthe pans C, at the ends adjacent to the piece B, are provided each with a runner, f, secured tothe bottom and side of the pan. The opposite ends of the pans C are each provided with a flange, f', through the lower end` of which passes la pivot, f2, securing the pan to the end piece B of the casing. The latter is provided with a central vertical slot, b2, and on each side with a diagonal slot, b3. Astud, b4, projects from the outer side of each of the anges f of the pans, and extends through the diagonal slots b3 of the end piecev B', and

upon these studs are mounted friction-wheels.

Gr G, one on each side of the central slot, b, of the end piece B'.

It will vbe Vobserved that by the construction thusfar described the two pans C C may be readily tilted or dumped by means ofthe bellcrank' lever D; also, it will be clear that when said pans aredumped in opposite directions:

by means of the bell-crank lever the friction-v wheels, which are journaled upon studs of the pans, said studs projecting through the diagonal slots of the end piece B', will be carried lwith the pans in opposite directions, and after the dust in the pans has been removed the lat- Qter may be quickly restored to their operative ,position by striking them upon the floor. Fig. 7 is a section taken through one Hrepresents the brush, ofthe usual circular orroller form, secured in position by the friction-wheel, h2, anda central pivot or stud, h3, projecting from the latter. I `represents a bell-crank lever, pivoted to the inner side of` the end piece B of the cas-v ing by a pivot, fi. The inner end of this lever One end ot' the is provided with a bearing, i', adapted to receive the stud h of the brush-roller. The upper end of the lever I projects through a slot, i2, of the casing and registers with a notched plate, i3, secured to one side of the slot t2.

J represent a bracket having its horizontal portion 7' secured rigidly to the under side of the adjacent end of the overhan gin g top brace, E. The depending portion j of the braeketis provided with anupperandalowerslot,lettered lfand j respectively, which are adapted to receive studs from a sliding piece, J The latter is also guided between studsj, extending from the inner side of the bracket, and is provided near its lower witha bearing, ji, adapted to receive the stud h3 of the brush-roller.

A horizontally-sliding plate or finger-piece, K, is interposed between the bracket and the bearing-piece J. It is provided with a diagonal slot, K', and is held by means of a headed stud or rivet, K2, which passes through the slot K and the slotj2 of the bracket. By this construction the friction-wheel h2 of the brush is held between the wheels or rollers G G, with which it has frictional contact when the device is in operation. It will be observed that the brush-roller may be adjusted vertically by means of the lever I at one end, and by the sliding finger-piece and its connections at the opposite end. v

L represents a handle-socket provided with arms Z, the ends of the latter being bent outwardly and secured pivotally in bearings M, secured by screws m to the casing. An elastic washer, m', surrounds the ends of the arms l withinthebearings M. A catch, N, preferably of spring metal, is secured to the top brace at about the center of the latter, and adjacent to the handle-socket L. A rigid brace or bracket, n, secured to the casing below said catch, and to the under side of the latter, serves to support and give rigidity to the catch. By this construction the socket L is adapted to be turned over the catch and securely held, the necessarysprin g action or yielding of the parts being secured by the use of the elastic washers m.

Instead of making the catch N and brace or brackets a of two separate pieces, as above described, they can be made of a single piece of metal and answer all the necessary purposes.

In Fig. 5 is represented a modification of the end piece B. In this figure the diagonal slots b3 of the end piece B are avoided and the corners of the piece are cut away, and the ends m2 m2 of the pans form part of the end piece, and to these ends m2 m2 the friction-wheels G G may be secured by studs,as represented in the other figures.

By the construction and arrangement herein described I am enabled to dispense entirely with casin gs for the friction devices, and moreover produce a friction device of few and simple parts, easilyoperated, and durable and reliablein use.

It will be apparent that I may make many slight alterations in the details of construction of my improved sweeper without departing from the spiritof my invention. HenceI would have it understood that I do not limit myself to the exact construction shown and described, but reserve to myself the right to make all such changes of form and construction as may properly fall within the scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
