SPECIFICATION forming part f Letterslatent N0. 471,@86, dated March 15, 1892. Application tiled August 15, 1890, Serial No. 362,131. A(No model.)

Be it known that L-SILAS I-l. RAYMOND, a

citizen of the United States, residing at Grand `."Rapids, in the county of Kent and State of ticularly describedand claimed.

,Michigan, have invented certain new and u sefullmprovements in Carpet-Sweepers; and I do hereby declare the following to be a. full,

clear, and exact description 'of the invention, such `as will enable others skilled in the art to which tappertains to make and use the same.

My invention relates, to improvements in carpet-sweepers. Its obj/ectisto provide a4 sweeper that shall be clrap, durable, andcon-- venient to operate; and it consists in certain details of constructibn hereinafter more par- Reference being had to' the accompanying drawings, Figure 1 is one end elevation o'f a device"embodying my invention, with portions removed to better-show the construc` tion; Fig. 2, a plan of one end of the same in, tact; Fig. 3, a vertical section of the same on the line Y Y of Figs. 1 and 2; Fig, 4, a vertical. section on the lin'e X X, and Fig. 5 a vertical i section of the corner roll H on the line Z Z.

Likeletters refer to like parts in all the figures.

A is the case, which may be made in any convenient form and provided with openings at'the under side of each end to accommodate the brush-shaft E, which is provided `with a friction-pulleyE, and a convex jour.

nal E. at each end, which' latter engages with a 'depression -in thelower end ot' a. flexible pendent hanger C, which depends from the bai lplate C, and is adapted to hold the brushshaft in position lor to be sprung outward,re

leasing the end of the journal for permitting the brush-shaft to be detached from the case. Plate C is cupped to receive'the wood friction-plate K and provided with spurs B,' t

prevent the said plate K from turning in said` cup. The bail-plate C is also provided with lugs. G C to receive screws for securing it to the case A. The ends of the `bail are also through the respectivecenters of said bail position, while permitting said position to be .shifted at pleasure by applying proper force.

'lhe driving-wheels E are secured upon the respective ends of the rods J, which extend through thecase from side to side and project therefrom sufticient to receive said wheels. Within openings in the end walls of the case and surrounding the rods J are lexible bushings ,1, made, preferably, of rubber, having a central opening for the rods J, and radial arms with their ends in contact with theend walls of the case, to secure greater flexibility. These bushings provide elastic or movable points of attachment forthe rods iJ andservegto secure spring-pressure conr tact of thedriving-Wheelswith .the pulleys E onthe brush-roll, and also to mount the entire deviceon springs. v

' JFis a fender=plate attached at each of its ends near the 'corners of the case A,extended outward and thence parallel with the end of said case outside of and in contact with the ends of the rods J. This serves to protect *the inclosed parts and keep the wheels E in position at each corner, with its middle part under the end of the fender-plate F; andsecured by the same screws is a yoke G, be-

tween the arms of which is journaled a roll H, consisting of an inner metal tube H and an outer tube H', ot rubber or other suitable material. Said roll is arranged with its axis vertical and so located as to project beyond the planes of both theisides of the core and the fenders F, thus preventing other contact withthebase or furniture. The rolls, being free to turn when coming in contact with any object, will not be so likely to produce marks upon the same or resistance due to friction,l but will roll. freely along thesurface otl the lwith the fender-bar F by providing the same with suitable lugs or projections; btI prefer the construction shown, as it permits the use of plain strips of metal in their construction.

A is the usual ,dust-.pamhaving .any convenient means for discharging its contents's thus forming no part of myinvention.

..9tef .v same. The yokeG may be made integral p 1. In a carpet-sweeper, bail-plates attached to each end of the case', friction-plateso L able material attached fo said bail-plates, a

ends andbail-plates'andserves mettant: the hail and secure the required friction between the plates K to hold the `bail in any desired bail having corresponding friction-plates at each end, and bolts `a taching said ends and plates, substantially as described.

2. In a carpet-sweeper, bail-plates provided with cups and spurs, friction-plates secured bysaid cups and spurs, a bail provided at each end with corresponding cups, spurs, and friction-plates, and bolts passing through said plates and bail ends, substantially as de -y with cup-bearings, a bail having corresponding cup-bearings arranged at each end opposite to and adapted to engage the said plates, friction-blocks between said plates and bail ends, and means of attaching the bail ends to the plates, substantially as Vset forth.

5. In 'a carpet-sweeper case, and in combination, with traction-wheels mounted upon rodsv which extend. longitudinally... through said oase parallel-With the brush-shaft, elastie bushings I, surrounding said rods,having radial arms and arranged in the end walls of said case, substantially as and lfor the purposes set forth.

In testimony whereof Iaix my signature in presence of two witnesses.
