CARPET-SWEEPER.

. Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed May 28, 1910. Serial No. 563,957. 1

'To all whomit may concern:

Be it known that I, VILLIAM F. MCGLIN- new, a citizen of the United States, resid-- ingat Cincinnati, in the county of Hamilton and State of Ohio, have invented certainnew and useful Improvements in CarpebSweepers, of which the following is a specification.

The object; of my invention is to provide a. more simply constructed and more efliciently operatingrunning gear and brush- ;hjvingmechanisni for a carpet sweeper,

' andto provide means for adjusting the;

Jarush tothework and for removahly mount ing the brush in the sweeper in a moreslmpleand etlicient manner.

- My invention; .consistsin the combination inga sweeper of the 'type in which the brushis .rota ted.by direct contact with the periph-i levertogether-with novel means for adjust-'- ably applying said wheels to said brush; as

cries of the wheels of the sweeper, of a -bnush adjnsting. mechanism comprising a:

well as in the other details of construction and arrangement as will hereinafter be more fully described and claimed.

In the drawing: Figure 1 is a plan view of one end of a sweeper embodying my in vention. liiggfl is an end view of the same showing thcileverin position for releasing thebtush-from the sweeper. F ig.t3 is a vertica'lsection on the line :12-w of Fig. 1- with the lever holding the brush in posit-ion for operation the wheels being removed from their-spindles.- Fig. 4 is anenlarged. detailv perspective view of, the lever. Fig. 5 1s a detail iers )ective view enlar ed of the wheel bracket-parts, including the plate to prei 'cntt the accumulation of raveliiigs. ig.-6,is, a-detail perspective view of the inside part of, the mounting having the slot.

The casing 1 has a flat top 1 and sloping sides 1" as is usual 'in the construction of sweepers Of-tlllSClltlIilCtOI. This casing also sides 1",

basin-set ends. which, together with said flat 'top l, sloping sides 1, and verticah incloses a space inside the "j sweeper the bottom of which'is formedby' pans 1"-liinged at 1" and tilted by any well known operating device such as the pu'sh- IOdHl and normally heldclosedby the spring -1.". Lying within the casing-and extendingdownward through a space .be-. tween .thepans 1 is the brush 2, This brush 2 extends outside the casing through tween-1 said.- tmountmgsx and slots 1*" in the in-set ends 1 at both ends of the sweeper, and. is provided with pulleys 2 to be engaged by the wheels 3 which havol tires-3' of rubber or similar material to make effective frictional contact with the. pulleys 2. of the brush-and rotate the brush when the wheels rollover the floor or other surface to b'e swept;

The foregoing. de'scriptioiisets forth details' common to carpet sweepers heretofore disclosed, b'ut it.is.- in thedetails 'andvin the arrangement ofid'tails', in combination with the foregoing" details;.. as hereinafter described; that my invention-i consists.

'in their inner sides 'lntflflvlllcll the spindles 2 -0 5 thebrush extend. andi-in wliich said. spindles may rotate and be adjusted vertically toadjust tll blllsl'l up and down in the sweeper and adapt the sweeper for operating npon surfaces ofditl'ei'entcliar- 2, sowthat as the lefver ismoved-tltc spindle 2 D will becarriedup; anddown" in are slot a and ivillloccupy various-positions longitudi nally ofthe' slot- 5"in--.t-he extension :ofjthe lever. The, lower end'ot the slot 4 in the mounting .4 is also-opem'andtlie lever 5 and its extension and-the slot' 5" therein are so proportioned thatttlTe' open end of the slot '5" may coincide witli the open end of the slot 4-in.sueh a manner" as to: allow the spindle 2 'of the'brush 2 to escape. from said slots, as-is bestsh'owlrin'-Fig.'2 of'tlte drawmg. The lever 5 has another extension 5 lever 5 only during the process of inserting and removing the brush from the sweeper.

by the means above set forth.

The lower part of theslot 6 is widened and is provided with a series of projections 6", while the part of the lever 5 adapted to ass along this part. of the recess 6 has a ongitudinal slot 5", which may receive any one of the projections 6" in the widened part of the recess 6' in the plate 6, thereby holding the lever 5 stationary in various adjusted positions and providing a corresponding number of adjusted positions of the brush for operation in the sweeper. V

The part of the lever 5 comprised by the extension 5 is made resilient sothat it will spring in and automatically admit the'pro jections (3 into its slots 5, as the lever is brought in the region of said projections.

From the foregoing description it will be seen that to insert the brush into the'sweeper it is only necessary to bring the lever 5 up until the open ends of the slots5 and 4* coincide, then slip the brush into the sweeper, passing the spindle 2 of the brush through the coincidingopen ends of said slots and bear inwardly of the sweeper on the brush, thus bringing the extensions of the levers upward and inward, and bringing the extensions 5 downward and outward until the slots 5" therein admit the first projections (3 of the plates 6, whereupon the brush is held positively in position-for operation. Then if it be desired to-adjust the brush farther up in the sweeper the adjustment may bc'accomplished bypressing the extension 5" outward, releasing the lever and bringing it so that the desired projection ti enters the slot of the lever. When the levers have been brought down to hold ,the brush in operating position they will lie below the surface of the fiat top 1 of the casing and thus be out of position to engage with any objects under which the.

sweeper is passed in sweeping, such as chairs and other articles of furnlture, so

that the marring of such articles by the en gagement of these levers is avoided. This position of the lever is best illustrated in Fig. 3 of the drawing.

W' hen the brush 2 is adjusted up and down with its pulley 2 lying between the wheels 3, it is necessary that the wheels be allowed to be displaced in a general horizontal direction, moving inward toward each other when the brush is lowered, and moving outward away from each other when the brush is raised, as will be seen upon inspection of the drawing. To mount the wheels in the sweeper in a simple manner to allow such horizontal displacement and at the same time maintain the wheels in contact with the pulley 2 at all times and at alladjustments, I provide brackets? for said wheels which brackets comprise arms '4' having pivotal connections 7*" with tl1e-in-set ends 1* of thecasing near the top of the sweeper and extending down-' ward and provided at their lower ends with horizontal outwardly extending spindles 'l" on whichthe wheels, are rotatably mounted.

the engagement against their outer sides of the mountings 4 that extend across the ends of the sweeper, said mountings having lugs t with smooth inner faces to engage with may swing on their pivotal connections 7 and carry the wheels on the spindles 7" outreat radius --to constitute a substantially resist the outward movement of the wheels as carried on the arms 7 springs 7 are provided. Each of these springs consists in a part fixed to the in-set end 1 of the casing and extending upward forming a loop, and

pivotally attached to the spindle 7" immediately adjacent to the arm 7*.

For forming a guide for the arm 7" its to, a plate 8 is secured to the in-set end 1 of the casing by lugs 8' that extend inward, whereby said plate 8 is separated a short distance from the in-set end, leaving .a space between it and said end. This late '8 has a horizontal slot 8, and the spin le 7 of the wheel 3 extends through this slot to receive the wheel 3, which wheel bears inwardly against the outer side of the plate 8. Thus -the spindle 7 may swing inward and outjward with the arm 7 along this slot 8 in the plate 8, and the wheel bearing thereagainst may slide 'therealong during such displacement. This plate is comparatively thin, and while serving the pur oses of a guide and a bearing for the whee also serves to interrupt such ravelings as arev taken up by the wheel, the ravelings passing inside the plate and down through thespace between it and the in-set end 1", being thus separated from the wheel and their accumulation on the wheel and the spindle avoided, so that. the clogging and excessive wear on the parts ordinarily caused by the accumulation of such ravelings are eliminated.

' The mounting 4 has an outwardly projecting boss 4: with a recess 4 in its upper side, and an outwardly projecting lug 4 is located immediately above this recess. The bail 9 Said wheels 'are held on these spindles by the hubs of the wheels Thus the arms 7- horizontal displacement of the wheels. To

ward or inward along an arc of sufficiently.

then extending downward with another part spindle 7 b and the spring 7 attached there- I 4 has an eye 9'" that fits onto the lug 4 and lies in the recess 4" in the boss at", the sides of said recess 4" being made to conform to the'eye 9 of the bail 9, so that when the bail pivots on the lug 4 it will also turn closely against the sidebithe recess, whereby the boss 4" may constitute a reinforcement. of the lug 4 as an attachmentof the bail to the sweeper. Preferably an opening 4" is provided in the lower side of the recess 4" to permit-the escape and prevent the accumulation of obstructing 'matter in the recess around the eye of the bail, and a plate4 maybe riveted onto the boss P extending up past the eve of the bail-to hold the bail in place. This boss 4' and the other parts associated therewith for the attachmentof the bail, are mounted immediately outside the slot 4 in the mountin 4, so that the attachment ofthe bail isc losely adjacent to the bearing of the brush in the sweeper. Thus the propelling power at the sweeper is applied theretoat the mostetfective- P int to he applied directly to the brush and avoid the tendency to the-tilting of the sweeper, as is the case if the bail be attached to'the sweeper at a point considerably above the bearing of the brush.

In the combination of a simple mechanism allowing a perfect verticatadjustinent of the brush in the sweeper thus maintaining the brush in its position in the middle of the sweeper. and maintaining the distance between the brush and the two pans equal at all adjustments, and effecting such vertical adjustment with the use of a lever having a simple means for holding it positively in its various adjusted posit-ions, while atthe same time providing a simple and effective corresponding adjustment of-the wheels of the sweeper which bear directly on the brush pulley, and thus transmitting the power in the most simpleand effective manner at all adjustments of the brush, the operation of the sweeper is considerably improved while the simplicity of construction with a small number of different parts to be assembled, make the cost of construction small.

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

1. In acarpet sweeper, thSE'combina-tiOn' with a casing, wheels, and arusli rotated through engagement with said wheels, of a mounting for said brush having a vertical slot. and a spindle for said brush bearing in and held against horizontal displacement by the sides of said vertical slot, and a lever with a slot extending atan angle to said vertical slot in the mounting and receiving said spindle to hold it against vertical movement in said vertical slot, or to move said spindle vertically insaid vertical slot, the sides of the slot in the lever and the sides of the vertical slot in the mounting, within the region where-said slots are adjacent, formvertical slot, and a spindle on said brush vertically adjustable in said slot and rotatable t herein,-of a lever with a slot extending direct contact with the peripheries of said .wheels, a mounting for said brush having a at an angle to the vertical slotin the mountin and receiving said spindle, whereby the spindle is retained in the vertical slot and is adjusted up and down therein, the lower end of the vertical slot being open and-the lower end of the slot in the lever being open and said open end of the slot-in the leverrbeing adapted to coincide with the open end oi the vertical slot to allow the brush to be re; moved from the sweeper, substantially ms specified.
