To aZZ who-m it may concern: I l

v Be it known that we, WILLARD A. MonmsoN and FRED L.l BRYANn/citizens of the nited States,V and'fresidentsfof the city o t Chicago, in the count ofCook and State of l Illinois, have invente 'i a certain new and use# ful Improvement in Carpet-Sweepers, of

which the followingisa'iul'l, clear, concise, and

accompanying drawing, forming a p'art of this Our invention' yrelates to improvements in' carpet sweepers, the object being to provide sinipie and cheap tov manufacture, and one that is .durable under conditions of 'actual USO'.

'The' invention inl its 'referred embodi-v ment consists ie'ertajin details of construction, arrangement and combination of parts, Y hereinafter described andp'articularly pointed out in the claims. l

In' the' accompanying drawing, in which the' same reference characters designate like parts throughout the several views, Figure 1 1s 'a' perspective view of a carpet 'sweeper emlan view thereof, 'portions being in. section; ig. 3 is a transversesectional .view on the line 3`3 of Figi?, 'looking in the direction of the arrows; 4 is a sectional view of the line, 4-4of Frg.2,.and showing the outer wall removed; Fig. 5 is a dethe mean'sfor raising and lowering the dust' pan-.and the rollers supporting the same atthe forward edge; Figs.

nested with lthe drive wheels; and Fig. 8 is a sectional view on tha-line 8-8 of y6,

arrows.

In t 'ese il ures, 2, designates 'the top of the casing or ox of the' sweeper; 3, the ends thereof, and 4' the rear wall of the same. A

froiitandback walls of' the casing to support dust bjbX, 6, from the back portion, 7 ofthe any esir'ed manner. l e brush 9 'is mount-l. ed in the forward portion of the casing, the

into which the bristles of the brush are set, andA ,which is journaled inthe outer plates', g 3, of the casin lupon pins '1841'. The front of the ca'sin f is lrmed of a flexible member, 1.1, preferab i necessary lto old them iirmly f plate vinto the inner.:v

y of indiarubber and secured at its upper edge in a;

groofe, 1,2', formed in the front edge of the top plate, 2

theouter in Fig. 2. This flexible front is preferably ,provided with` thickened portions, 15l and ,and at its side edges, 13, bybe- 5 ing clamped between the inner plates 10a-nd"v plates, 14, of the end Walls, as shown 16, forming strengthening ribs for the same,

sweeper may be pushed against any articlev ofiurniturewithout injuring the same. `Slt moreover ermits the same to sweep closely vto the wal and about the legs chairs, or other furniture, since when pushed against any object it will be indented and of tables, Y

allow thev bristles of lthe fbrush toV extend up' tothe same. may be employed to secure this flexible por--l suitable shape oreontour'may be imparted' to the same but we shown and/described. Thebrush 9 isiso connected as to-rotate in the same direction whether thesweeper is Ol course, anydesired' means prefer at; present those l tion to the remainderv ofv the 'ea-sing and any i m-ovedbaokwa'rdor forward/The mechan-v i ism .for carrying this into effect comprises a trainv of gearsmounted between the fletes, 1G and '14, ofre'achof the end vWalls B'of the easing. ,Upon each end of thev roller 9 is f mounted' a pirn'o'n, 18, between the said two platesl of `the ends. AThese end walls, 3, -erably comprise the plain vouter late 14, forming a smooth fiat exterior to tige the casing, and the inner/plate, 10, which is prefend ofy 'preferably ,of stampedsheet steel or other r i suitable material, havingits main body ortion spaced far enough away from the p ate,

14, to rovide roomA between them for thel gear W eels .connecting the drive wheels and the brush. :In order to accomplish this the forward edge, stamped outwardly, and suita the 'outer ed fes of the plates and wherever gether by `suitable screws, rivets', or other'.

l19, of the inner late, 10,-is

lespacing blocks andfstripssuch as'lOjare -placed at in place withsuitable `fneans 'passing through the outer The forward edge, 19

providesroom to enable Ithe bristles oftherush to vbe set at an angle as shown in ,Fim

2, whereby it sweeps the full widthof tle;

casing.

,The drive wheels,y 25, are mountedupon'A l the flange, 32, upon the drive wheel.

I.:g'oressed against the inner periphery of the ',ilange, 32,r 'jy the free end of a cireul""fspring, 30, extending about said boss and sof- 'the `ilange.

,l mediate gears.

cured tnereto at one end as shown at 31.v A-washer 27 is placed outside the boss 27` to secure the pawl and spring in place.

When the parts are assembled lthe flange, 32, is concentric with the boss, f7, and the pawl, 29, presses against the inner periphery These arts form a' clutch between the drive whee s and the gear wheel 33. In operation, as shown in Fig. 6, in event the drive wheel 25 is moved to the right, the friction pawl 29 w-ill be permitted to be moved to a vertical position 4by the Spring 30 and the outer end of the pawl will engage the inner periphery of the flange 32, causing the circular boss 27 and the gear Wheel 33 to rotate with the diive wheel 25. If the wheel 25 be moved to the left, then the pawl 29 will disengage from the inner periphery of the flange land the wheel 25 will revolve without operating the gear wheel 33. By using two of such clutch members, one for each drive wheel, and by arranging one clutch member to operate in a direction opposite to that of the other, it

will be seen thatv the brush will always be rotated in the same direction no matter in what direction the sweeper is turned.

In the train of gears at one end of the casing as shown in liig. 3, there are four intere mediate gears, 34, each mounted upon a suitable axle carried by the plates, 10 and 14, while in the train ,shown at the o iposite end there are three similarly 'mounted inter-I The fresult of this arrangement is that'tlie brush in oneinoveinent ofI the casing is rotated in the proper direction lby one ,set of gears, and when moved in the opposite direction, the brush is rotated in t e same direction by the opj'iositc, set of y i gears, the friction clutches being connected with the gears, 33, as'stated.v vBy this arrangement, the mechanism for .operating the brush is entirely in'closed and protected v from dust and-injury and thc brush is not divided and therefore weakened. g

-The dust pan, 35, is pivoted at its forward edge between thc end walls of the raising4 and is supported 'at its foi'\vard.cnd b v means of a spring, 36, as shown in Figs. 3 and Rollers, 37 are provided'iii the forward edge of the dust pan and carried upon opposite ends of a.

spring rod, 38, pivoted at its center u on a its forward edge and passes through the top plate, 2, by means of which'the an may be depressed in order to empty t e collected dust and dirt from the same.

A handle, 42, is provided for the sweeper in the usual manner and carries a f'ork, 43, the side members of which have inwardly extending lu s adapted to enter suitable apertures in t e ends, 3, of the casing. The said ends are suitably depressed as shown so that 'the said members of the fork 43 will not extend beyond the faces ofthe ends.'
