CARPET-SW'EEPER.

SPECIFICATION forming part of Letters Patent No. 469,714, dated March 1, 1892.

Application filed March 9, 1891. Serial No. 384,243. (No model.)

To all whom, it may concern.-

Be it known that I, EDMUND E. PEoK, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Carpet-Sweepers, of which the following is a specification.

This invention relates to that class of carpet-sweepers in which there is a central rotary brush receiving its motion from wheels at the ends of the box, the dust being delivered into pans that are pivoted and capable of being swung open for the discharge of such dust; and the invention relates to the combinations of devices hereinafter set forth.

In the drawings, Figure 1 is an end elevation, portions of the box and of the end frame being removed and in section to illustrate the construction of the sweeper. Fig. 2 is a plan view at one end of the sweeper,-the parts being broken open in such a way as to show the internal construction, the brush being indicated in dotted lines; and Fig. 3 is a partial vertical section at the line a: at, Fig. 2. Fig. 4 is a diagram showing the levers and sweeping-inclines detached.

The box itself is formed of ends A, with upper and side inclosures A A and the brush B occupies a central position in the sweeper, and the bristles of the brush are preferably applied in spiral lines around the central axis B, and there are journals 2 at the ends, which journals are received into the bearings in the end frames 0. These end frames G are usually of metal, curved at their respective ends, and passing around and united by the screws 3 with the'side portions A of the sweeper-box, and there are spaces between the end frames 0 and the ends A of the box sufficient for the reception of the actuating wheels, as indicated in Fig. 2. These actuating wheels are of metal, as shown at D, and around each metal wheel is a tire 4, of flexible materialsuch as rubbersecured thereto by suitable cement or otherwise, and the periphery of the tire is roughened by diagonal corrugations crossing each other and forming projecting points in order -that such roughened rubber tires may be more reliably acted upon by the carpet to 1'0- tate the wheels, and at the same time such rubber tires will rotate the brush by acting upon the end pulleys E of such brush, these pulleys E being corrugated upon their peat the ends of the coiled springs F. It isto be understood that there is a coiled spring at each end of the machine, and the middle part of each coiled spring is fastened to the inner surface of the end frame O, preferably by projecting ears or lugs 5, which are bent over to clip the middle portion of the spring after such spring has been inserted between such lugs, and the end portions of the coiled spring are wound similar to volutes, and then the portion 6 of each-spring forms an axis for one of the actuating-wheels D. Hence it will be apparent that when the box of the sweeper and the frames O are pressed toward the floor the coiled springs F yield, and in so doing the axes 6 are drawn by the springs toward the pulley E of the brush, and thereby a greater force or pressure is exerted by the actuatingwheels against the pulleys E to obtain the requisite friction to rotate the latter. The handle G is secured into the socket 7 of the bail H, and this bail at its lower ends is turned inwardly to form pivots 8, which are received into slots in the end portionsA of the sweeper-box, and this bail and handle can be swung over to either side of the sweeper, as usual, and when turned up vertically such bail and handle may be held from falling over by a spring-bow I, fixed upon one or both ends of the sweeper box and adapted to receive a pin 9 on the bail H, such spring-bow being bent ing the dust and particles of foreign matter up into the pans, because the edges of the pans have been at some little distance above the floor. One feature of my present sweeper relates to movable inclines K, up which the dust is swept by the brush, and which movable inclines are either raised or lowered, according to the direction in which the sweeper is being moved-that is to say, the brush where it is in contact with the carpet is rotating in the same direction as the sweeper and the incline at the front side is brought down upon the surface of the carpet, or nearly so, in order that the dust may be caught upon suchincline and carried up into the pan, and the incline behind the brush is raised up out of the way, so as not to be injured. The movable inclines rest at their backs against the cross-bars L, and there are projecting studs 10 at the ends of the inclines, andthese studs are received by the ends of the bent levers M, which are pivoted at 11 upon the ends A of the sweeper-box, and such bent levers extend up with nearly vertical ends 12 at opposite sides of the pivots 8 of the bail, and such bent levers are connected by links 13. Hencesuch bent levers M are acted upon by the pivots 8 ofthe bailand raise one of the movable inclines K which is indicated by dotted lines, .being raised up out of the way,-so as not to be injured by=the movement of the sweeper. At the upper edges of these inclines teeth are provided, asshown at 14, the object of these teeth beingito comb ofi. from the bristles of the brushany-hairs, lint, or other-substances that might otherwiseadhereto the brush and finally interferewith'its usefulness, and upon reference to Fig. 1 of thedrawings it will be observed that the bristles of the brush are moving toward the teeth 14 of the movable incline,whichis elevated and shown by dotted lines, andthese teeth are cleaning such. brush, and thevbrush is simultaneously cleaningzthe teeth of the other incline, which is? shown-sectionally, because the bristles of mm brushare moving from the butts toward thej pointsof the teeth,and of course theseopera-i tionsrare reversed when the sweeper is moved inthe opposite direction, the teeth of tone in-; clineservingito free the brush from foreigni substances, while the .teeth of the other incline are beingcleaned ofaccumulations byf thefbrush. By making the sides of theibars :L that are next to the inclines K concave the said-. inclines slide thereon in the arcs of cir cles.

:Between the cross bars L and thesides A pans can assume the positions shown by full lines in Fig. 1,0r such dust-pans can be swung into the inclined position indicated by the dotted lines at 16, and there are springs O to act upon the dust-pans and retain them in their normal positions foruse, and the dustpans can be swung-by the yoke-piece P and links Q, that are pivoted from the ends of the yoke-pieceto the respective dust-pans, and.

upon the yoke-piece is a finger-piece P, extending up throughamortise in the top of the sweeper-box, so that by grasping the fingerpiece and drawing it andthe yoke-piece upwardly the dust-pans will be swung open for the contents to drop out with freedom, and when the finger-piece isliberated the springs 0 return the dust-pans to their normalpositions, and it is advantageous to make use of a catch 17, adapted to hold the yoke-piece and the finger-piece with the pans .open. This catch 17 may be upon one side of the fingerpiece P to hook over the top of the sweeperbox at the mortise in the same,so as to retain the finger-piece when the pans are opened. It is advantageous to make the sides of the cross-bars L that are adjacent .to the dustpans as concave curves struck from the piv- -ots 15, so that the dust-pans can swing freely when being opened; but dust will not pass in between the pans and the cross-pieces, and; the swinging outer edges of the pans close up into rabbets 18 upon the lower edges of the sides A of the sweeper-box.

It is advantageous to provide rubberbands or stripsR to form fenders to preventingury to furniture by the sweeper, and to securethese rubber bands or fenders R in position .I- pass the ends of the rubber through mortiseslQ in .the end frames 0 and provide upon theendsof the rubber buckles 20, fastenedto the'rubber and hooking upon projecting pins 21 .at the inside of the endiframes 0,501tl1ttt when either rubber becomes broken or injured it may be removed with facility, and by thismeans the rubber is securely held to the metal end frames 0, so as to prevent the rubber slip- .ping off, as frequently occurs when a band of rubber only is made use of passing .cntirely around the sweeper-box. In teases -where there have been movable inclines for the brushes to sweep against theyihave not .re-

.ceived a positivemotion,and;hence thewrong one might be lifted and the other injured or injure the carpet by scrapingthereon. Swinging dust-pans have been used; that theinmovevment was so limited that the-dust oftenyhad to be removed by the finger "at the risk of such pan closing. andpinching the hand. .In

the ordinary sweeper the pan is at such .a height from the carpet that sand and-gritty substances are not easily swept up andilight substances-such asfeathersareoft-enblown about by the wind from the revolving brush. These difiiculties are rectified by my present. improvements. Springs have been used :at the axles of the actuating-wheels; but they have either been in the box and liable to interfere with the pan or else they were difficult to replace, if broken, because of passing at both sides of each wheel. In the present improvement the wheels, being received on the ends of the spring, can be easily removed or replaced and the spring properly bent or a new one substituted with facility.

In my improvement the sweeping-incline that is raised up comes in contact, or nearly so, at its upper edge with the brush, and in so doing intercepts the air-currents, so that dust and light substances are not carried down and out of the'box.

I claim as my invention- 1. The combination, in a carpet-sweeper, of the brush B, its pulleys E, the actuating-wheels D, the wire springs F, coiled as volutes and having at their ends theaxes for the wheels, and the connections for the springs to the end frames of the carpet-sweeper, substantially as set forth.

2. The combination, with the brush in a carpet-sweeper and the wheels forrevolving the same, of dust-pans, movable inclines up.

which the dust is swept, and connections to such inclines and between the same and the bail of the sweeper, whereby the inclines are raised and lowered, respectively, according to the direction in which the sweeper is being .moved, substantially as set forth.

3. The combination, with the sweeper-box, the brush, and the dust-pans, of movable inclines, the handle and bail for giving motion discharge of the contents, substantially as set forth.

5. The combination,in a carpet-sweeper, of a box, a brush within the box, actuating- Wheels and pulleys, end frames outside of the wheels and pulleys, spring-supports for the actuating-wheels, movable inclines and levers for actuating such movable inclines, and a bail for giving motion to the sweeper and raising and lowering the movable inclines, substantially as set forth.

6. The combination, with the box in a carpet-sweeper and the end frames, of the rubber strips passing at their ends through mortises in the end frames, and connections for the ends of the rubber bands within the frames, substantially as set forth.

Signed by me this 2d day of March, 1891.
