Specification of Letters Patent.
Patented Sept. 24, 1907.
Application filed Oc ober 21,1905. Serial No- 283,812.
To all whom it may concern:
Be it known that I, Gosrn FRIEDMAN, of Jamestown, in the county of Chautauqua and'State of New York, have invented a new and useful Improvement in Carpet-Cleaners, which improvement is fully set forth in the following specification and shown in the accompanying drawings.
My invention is an implement for house use, the same being a device fol-conveniently cleaning carpets While secured to the floor, by taking up and removing loose dirt, dust and other litter generally.
V One object ofmy invention is to construct the device with parts adapted for cleaning a carpet near to the side walls of the room.
Other objects and advantages of the invention will be brought out and made to appear in the following specification, and the construction particularly pointed out in the appended claims, reference being had to the accompanying drawings which, with the reference characters marked thereon, form a part of this speci- Iication.
Figure l is a plan of the device with the propelling handle in transverse section. Fig. 2 is a side elevation seen as indicated by arrow 2 in Fig. 1, parts being broken away. Fig. 3 is an end elevation of the device, seen as indicated by arrow 3 in Fig. 1, the handle being partly broken away. Fig. 4. shows the device inverted, parts being broken away and omitted. Fig. 5 is an elevation of parts at the end of the body, seen as indicated by arrow 3 in Fig. 1, parts being broken away and omitted, and the brush spindle transversely sectioned as on the dotted line 5 in Fig. 6. Fig. 6 shows in elevation the overhanging brush and its connection with the main brush spindle, parts being broken away and axially sectioned. Fig. 7 is an end view, similar to Fig. 3, parts being omitted and the Wheel-axles transversely sectioned on the dotted line 7 7 in Fig. 1. Fig. 8 is a sectional detail on the line 88 of Fig. 5.
In the drawings, A is the body of the carpet cleaner, it being rectangular in plan, and made of any suitable material as thin wood or sheet metal.
B is a horizontal cylindrical brush to act upon or against the carpet when sweeping the latter, the brush being held to turn in journal bearings in theend portions b of the body A.
I O are a series of four equal rubber-tired carrying Wheels for the body A, held to turn respectively upon rigid axles a projecting horizontally from the end portions 1) b of the body A.
d are a series of equal spur gears, one being rigid with each of the carrying wheels 0, adjacent to and on the inside of the wheel next the body A, said gears being in positions to engage and turn intermediate pinions 0 c rigid on the reduced ends of the brush B. By
this means the brush is revolved to sweep the carpet as the device is rolled along over the same, the brush always turning in such manner that the part next the carpet moves in the direction in which the device is advancing along the floor.
With this carpet cleaner I employ a detachable overhanging brush D for sweeping the parts of the carpet next the base boards of the walls, around the legs of pianos, or other bodies This brush projects at the end of the body A beyond the adjacent carrying wheels 0, as
clearly shown in Fig. 1, in position to act upon parts of the carpet next the walls of the room not covered or reached by the main brush B. The brush D is coaxial with the main brush B and preferably joined to the latter by means of a squared shank 0, Fig. 6, occupying a similarly formed axial socket 0, Figs. 5, G and 7, in the end of the body f of the brush B, as shown, holding to place by friction. This brush D is removable from the brush l3, and the construction is purposely such that when said brush D is removed both ends of the cleaner are alike, that is to say, there are no parts of the device extending beyond the pinions c c at either end.
The exact form of the head g of the projecting brush D is not essential to this invention but I prefer to make it circular in cross section and slightly conical or tapering, as shown. Giving the head this form better enables the placing of the tufts of bristles or fiber 1' in positions to reach the margin of the carpet close to the wall, the tufts at the extreme end of the head being lengthened and placed in inclined positions, as clearly shown in Fig. 6, to overhang the end of the head.
In constructing these carpet cleaners I may sometimes find it desirable to place a brush D at both ends of the body A. g
This cleaner for carpets is provided with a propelling handle E, Figs. 2 and 3, for operating it, the handle comprising a branched part or bail F, the members h h of which reach down at the ends of the body A and catch into holding lugs or ears is, secured rotatably to the respective end portions 1) b of the body.
Dust-pockets or pans G G, Figs. 2 and 4, are provided for the device, one on either side of the main brush B, and held to turn on horizontal coaxial pins Z rigid with and projecting inwardly from the end portions I) ll of the body A. The planes of these dust pans are parallel with the axis of the brush B, their bottoms being slightly inclined upward at their outer edges, making the pans deeper at their inner edges, each pan being provided with a perforated spring catch m engaging with a headed pin a projecting from the side of the body A. These dust pans, thus held and controlled, are independent of each other and either may be turned downward for the purpose of discharging the accumulated dust therefrom.
The bearings in the end pieces b b of the body A, for
the brush B, are at the upper ends of vertical openings in the end pieces, and are in part composed of removable vertical blocks y y, Figs. 4, 5, and 7, inserted upward in said openings, the latter extending upward from the lower edges of said respective end pieces. These blocks are formed with concave semicircular ends to reach half around the journals of the part B, the edges of the blocks being V-shape to fit the correspondingly formed openings insaid respective end pieces I) b. This form of the edges of the blocks prevents lateral motion for the blocks, and they are further held in place in the end pieces b b by sheet-metal holders 2 z, Figs. 4, 5 and 7, held to swing in vertical directions upon pivots a, Fig. 5. These holders are formed with horizontally inturned parts b, Figs. 4 and 5, extending under the lower ends of the respective bearing blocks y y to prevent their escape from the end pieces b b, the holders being controlled and held normally in horizontal positions by engaging springs 0. These springs are shown in Figs. 3 and 8 as having lateral projections c which engage openings in the holders 2 which serve to prevent downward displacement of the holders and consequently oi the blocks.
When it is wished to take out the bearing blocks y y for the purpose of removing the brush B, the holders are disengaged from the springs and turned downward, as indicated in Fig. 5, away from the blocks, said holders being provided with projecting thumb-pieces d for conveniently operating them.
What I claim as my invention and desire to secure by Letters Patent, is:
1. A device for cleaning carpets, comprising a body with carrying wheels and propelling handle, and a brush within the body, the end portions of the body having vertical openings extending upward from their lower edges and constituting receptacles for the ends of the brush, removable bearing blocks in said openings, the openings and the bearing blocks having V-shaped meeting faces, holders pivoted near the lower edges of the body and having projections extending beneath the blocks, spring catches on said end portions engaging said holders to retain them in horizontal position, and means to rotate the brush.
2. In a device of the kind described, the combination with the body having end portions having vertical openings, removable vertical blocks in said openings having V- shaped edges fitting corresponding openings in the end pieces, holders pivoted to swing vertically and having horizontally inturned parts engaging under the lower ends of the respective bearing block, and flat spring catches at right angles to said holders for engaging said holders and holding them in normal horizontal position.
In witness whereof, I have hereunto set my hand this 18th day of October, 1005, in the presence of two subscribing witnesses.
