To all whom itmrty concern:

Be it known that I, .1 OSHUA W. SYKEs, a citizen of the United States, residing at Detroit, in the county of \Vayne and State of Michigan, have invented certain new anduse ful Improvements 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 theart to which it appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to new and useful improvements in carpet-sweepers and it consists in the construction'and association of parts, as hereinafter fully set forth, and pointed out particularly in the claims.

Theobject of the invention is to provide a carpet-sweeper that shall be cheap and simple of construction and one that may be readily opened and easily cleaned, said sweeper havin g stationary pansand means for effecting a vertical adjustmentof the brush, also a spring tension, normally applied, to keep the traction-wheels in contact'with the ends of the shaft of said brush, which object is attained by the construction illustrated in the accom- Figure 1 is a general perspective view of a carpet-sweeper as made in accordance with my invention. Fig. 2 is an enlarged transverse section through Fig. 1. Fig. 3 is a detail in perspective of the plate wherein the vertical adjustment of the b: .sh is accomplished. Fig. 4 is a detail of the spring employed for holding the sweeper-box in posilion while the pans are being dumped or cleaned. trunnions,

7 indicates trunnions or pins having a flange 7' formed integral therewith. Inter-. mediate of its ends ther'ear end of saidtrnn nions from said flange is threaded, asclearly shown in. Fig. 5. The threaded "portion of said trunnions is of such'sizefas. to snugly" pass through the various enlargementst of the corrugated slot in bar 4 and to receive a washer ornut 8 thereon. It willbe understood that an angled plate similar to plate'4 will besecured at each end of the sweeper-ML box, and a trunnion device,ias shownin Fig. 5, will be secured in corresponding openings.

6 in said bar 4, so that said trunnions will project inward toward box 1. v

9 represents a shaft which extends longi tudinallythrough box 1, said shaft having bristles projecting radially from its portion within said box,which bristles and shaft form the sweeping-brush, the outer ends of said shaft being formed into rollers or disks 10,

one only being shown. (See Fig.1.) Said 75" such depth and size as to snugly receive disks are provided with central cavities of trunnions 7, upon which they and-said shaft are adapted to be revolved.

11 indicates a bar, one of which is pivoted centrally at 11 in each end of box 1'. Piv-' oted to the ends'of said bar 11 and depend-:- ing therefrom are arms 12. Froject-ingJOut-J ward through box 1 from the loweren-ds of said arms 12 are pins 13, upon whichthe rub- '8' 1 T 5 Secured in the upper side of box 1 is a springher-tired traction-wheels 14 are journaled.

bail 15, the extremities of which are wrapped about arms 12,'and .the'spring tendency of said bail being such as tocause said arms to.

be thrown inward, carrying therewith wheels 14 and causing their rubber tires to impinge 1 upon disks 10.

It will be seen by reference to Zthatj arms 12 extend inward from a vertical line with their pivotal connections with bar 11,; which causes whee1s'1'4 to have a tendency to run inward or toward each otherf'as the weight of the sweeper rests thereupomjas will be readily understood.

15' designates a spring-wire device, "one"of Y which is securedin the outerendsof box 1,

said device having a central depressed portion into which the sides or frame 16 of operating-handle 17 are adapted to enter to hold the sweeper-hox and said handle in the position shown by dotted lines in Fig. 1. When in this position, catch 18 is operated to release cover 2, when saidcover maybe opened and the sweeper held at a'rmsJength and thoroughly cleaned or dumped Without the liability ofdust being inhaled by the oper atoror said dust settling upon ones clothing.

It will be understood that by'loosening the screws (not shown) which pass through the slots in the'angledportions of plates 4 to secure themto the ends of the sweeper-box said plates, as well as thebrush jou rnaled thereto, maybe gradually lowered, thus maintaining the brush at an even elevation, so that all wear thereof may be compensated for. If desired,this adjustment maybe accomplished, to a certain extent, by raising or lowering the bolts of trunnions7 in the series of openings 6 of the enlarged portions 5 of plates 4. This ineansfor the twofold adjustment of the brush forms a special and important feature of my invention.

' It will thus be seen that the construction and arrangement of parts hereinbefore set very cheaply manufactured, as its parts are forth produces a carpet-sweeper'that may be few and comparatively simple in formation and one which is not liable to get out of repair. r

Having thus fully set forth my invention, whatrl claixn as new, and desire to secure by Letters Patent, is-

1. In an attachment fors weepers, the combiuation of an end plate having a corrugated slot formed therein, a journal-pin provided with a reduced threaded stem adapted to engage with said corrugations whereby the jour nal-pin is held from movement in said slot longitudinally thereof, and a nutarranged to I engage the outer threaded end of said ste n, substantially as described.

2'; A driving mechanism for the cylindrical brushes of carpet-sweepers, the same consisting of a box having levers pivoted centrally therein, depending arms pivoted to said le vers, traction wheels journaled upon pins projecting from said arms, and curved springs secured in said box, its ends being adapted to move the free ends of said arms toward each other, substantially as and for the purpose setforth. I V

In testimony whereof I affix my signature .in presence of two witnesses.
