JOSEPH COOK ANDFLEMING COOK, OF CHICAGO, ILLINOIS.

CARPET-CLEANER.

SPECIFICATION forming part of Letters Patent No. 241,844, dated May 24, 1881.

Application filed May 17, 1880. (No model.)

To all whom it may concern:

Be it known that we, JOSEPH 000K and FLEMING 000K, both residing at Chicago, in the county of Cook and State of Illinois, and both citizens of the United States, have invented certain new and useful Improvements in Machines for Whipping or Beating Carpets, of which the following is a full description, reference being bad to the accompanying drawings, in which- Figure 1 is a top or plan view; Fig. 2, aside elevation; Fig. 3 a longitudinal section; Fig. 4, a similar section, showing the upper cords removed and the secondary support elevated at the rear; Fig.5, a side elevation, showing the machine closely incased; Figs. 6 and 7,

. views of the whips or heaters on an enlarged scale.

The object of this invention is to produce a machine for whipping and cleaning carpets in a thorough and expeditious manner, and to so construct and arrange it that various kinds and qualities of carpets can be given different and appropriate treatment.

The invention will be fully hereinafter described in detail and the improvements set forth in the claims.

In the drawings, A indicates the framing; B, the movable frame; 0, the hinged part of the movable frame; D, beams or rollers fornarrow or cross-moving carpets; E, beam or roller for heavy or longitudinally-moving carpets; F, tightening-roller for the upper supporting-cords; F F, tightening-rollers for lower supporting-cords; G, the whip-cylinder; H, a balance-wheel; I, hinged tail-boards; J, bar or roller upon whichthe outer ends of the tail-boards rest; K, roller under which the carpet passes; L, door for the dust-box; M, a hinged support for the frame 0 when raised; N, a hinged door or flap; 0, doors for closing the space when the frame is incased; P, a limitstop for the movable frame B; Q, dust-box; R, dust-passage; S, outer casings; T, sliding doors for admitting cross-moving carpets and closing the openings; U, steps; V,a hinged door or flap on outer casing; W, whips; a, upper supporting cordsor straps; b c, knobs for attaching the cords to; d e, lower supporting straps or cords; f g, knobs for attaching the straps or cords e,- f g, knobs for attaching the straps or cords d; h, hinges for tail-boards; h, hinge connecting the frames B O; i, ratchet for carpet-beam E; j, ratchet or look for the cord-tightenin g beam F; k, ratchet for carpetbeam D; 1, eyes or staples on whip-cylinder; m, rings in eyes I; n, snap-hooks or fasteners on whips.

The framing A may be made of planking, and it is to be made of suflicient width to take in the widest of ordinary carpets or double breadth of tapestry or Brussels carpets, and of a length sufficient to use whips thirty-eight inches in length and have them reach twothirds of the way across the carpet-support (l e, and of a sufficient height to give whips of that length a clear swing.

The base is provided with a dust-box, Q, which has openings R above for the admission of the heavy dust particles, and it is provided with a door, L, for cleaning it.

The rear end of themachineis provided with a carpet roller or beam, E, upon which the carpet to be cleaned is wound. This roller may be provided with hooks or with a cloth having eyelets or loops, to which the end of the carpet can be attached for winding, and this cloth should be long enough, when fully unwound, to let the least end of the carpet down to the whips. This beam is provided with a ratchetwheel and pawl, i, for holding it in any desired position.

WVe have also provided the machine with side beams, D, which are provided with attaching-cloths, similar to the roller E. These rollers or beams are used for stair-carpets and for other carpets when it is desired to have them move across the Whip-strokes instead of in line with them. The carpet may be attached to one of these rollers, and be drawn under the other by hand, or it may be attached to both and be wound on one as it is unwound from the other, with or without strain, as may be required. These rollers or beams are provided with ratchet-wheels and pawls 7c, and all of these carpet-beams may be provided with permanent or slip cranks orarms for operating them.

The cords a, which hold the carpet in what we call the first position, are fastened to the front bar of the frame O'by the buttons 0, over which they are looped, and at the rear end they arelooped over the buttons b of the tighteningroller F. This tightening-roller is provided with a stop, lock, or ratchet, j, to hold it, and the tightening'rollers F F are also provided with stops for holding against the strain of the cords or supports. The cords a are arranged with reference to the whips, so that the whips strike between them or pass down between them to the cords (l 0, when there is no carpet on the cords a, which arrangement gives the whips a better stroke on the carpet and avoids the necessity of taking these cords off when it is desired to use theloweronesin their first position or as shown in Fig. 3.

The lower carpet-supporting cords, d c, are best made of narrow rubber or leather belting, the ion gitudinalones, e, being made double and the transverse ones, d, passing between them, so that the longitudinal ones, 0, can be riveted or fastened together about midway between each strip or cord, d, and thus leave both free to be strained by their straining-rollers F F without getting them out of line, and also prevent the action of the whips from drawing down the cords d. A cheaper form can be made by simply fastening the two sets (1 together at their intersections. The strips or cords c are attached to the front by the buttons f, and to the straining-roller F by the buttons g. The cross-straps d are attached to the frame (J by the buttons f, and to the tightening-roller F by the buttons 9. It is upon this support that we propose to clean or whip stair-carpets and old or tender carpets which need more supporting, and for stair earpets it will remain in the position shown in Figs. 2 and 3, which we call the second position, while for old or tender carpets it will be put in the position shown in Fig. 4,which we call the third position. The change in position is accomplished by pulling the frame B back to the stops P, then lifting the rear end of the hinged frame 0 and supporting it on the door or flap M, which is turned up for this purpose. The pulling back of the frames B is desirable, as it gives a better stroke for the whips and corrects the carrying of the frame C forward by the hinges when the rear end is elevated. The tail-pieces I are hinged to this frame C, and their other ends rest upon the roller J, so that they will not wedge against the bottom and interfere with the pushing of the frame B back to its original position.

It is not essential that the tail-board be made in sections, but it is more easily handled and less liable to warp or spring when so made.

The whip-cylinder, as shown, is made of wooden heads and slats or bars, which is a light and cheap form, but it may be made continuous and of any suitable material. It is provided on opposite sides with staples or eyes 1, sufficient in number to attach all of the whips desired, and these eyes are provided with rings m, to which the whips W are attached by snaps a or other suitable fastening. It is evident that the rings may be attached to the whips and the eyes I be made snaps; but we prefer to make them as shown.

The whips are best made of leather or of rubber belting in the form shown in Figs. 6 and 7 and they are provided with a steel stiffening, (shown in dotted lines at 03;) but by making a stiff butt at the part a: ropes may be used for whips.

The whip-cylinder may be operated by hand or by power, and should be run at a speed to give fronrone hundred and fifty to two hundred strokes per minute.

The machine will do good service without being incased; but to save working in dust we prefer to incase the machine as shown in Fig. 5, which, to give the whips swinging room, brings it up, so that it is better to provide steps U and a platform around it. When the machine is incased the door N is raised and the doors 0 are swung around in line and the sliding door-Y shut down, either entirely or down to the carpet passing through and we propose, when there is power, to apply a suction-pipe and fan to the case, so as to take out the dust and discharge it out of the working-room. When used without casing, the rollers or beams D are made detachable, as they have to be taken off when the support is placed in the third position; but when the machine is incased they may be permanently attached.

in operation, for a heavy or strong carpet, it is attached to the beam E and wound upon it the free end is then drawn down over the cords at until within reach of the whips, when "the beating is commenced. It is pushed until a sufficient length is cleaned to pass under the roller K, after which it is pulled or drawn through from that end of the machine. Staircarpets are wound onto either of the beams D, which are provided with a suitable cloth for attaching the carpets, and are removed from one of the beams and wound onto the other, so as to keep them under tension, or they may be wound on one of the beams and be pulled through without winding onto the other, and with long whips two at a time may be run through. For cleaning old or tender carpets, the hinged frame 0 is placed in the third position, Fig. 4, the carpet wound on the beam E, and passed under the ti ghtenin g-roller F, which is not removed, and they are then passed through the same as stronger carpets in the first position, except that in some cases it may be necessary to use lighter whips, as the whips are easily attached and detached on purpose to have several grades of whips, so that they may be changed as necessity requires.

The cylinder G for an ordinary machine should be about five feet in length and from twenty-four to twenty-eight inches in diameter; and the space occupied for the whip attachinent-the eye, ring, and snapshould be from seven to eight inches. The whips should be about six inches apart, and the space between the roller and the board I should be sufficient to let the whips commence swinging under centrifugal action into position for striking new blows.

It will be understood that small or-easilyhandled carpets need not be attached or fastened to the rollers or beams.

What we claim as new, and desire to secure by Letters Patent, is-

1. Acarpet-cleaning machine provided with the upper and lower sets of carpet-supporting cords, the upper set consisting of longitudinal inclined cords, which permit the passage between them of the cylinder-whips, and the lower set consisting'ot' crossing cords, substantially as described, whereby the machine is adapted to be used interchangeably and support and whip different grades of carpets, in the manner and for the purpose set forth.

2. In a carpet-cleaning machine, the upper series of longitudinal inclined strained cords,

. a, connected at their ends to tightening-rollers,

and the lower set of crossing cords, d and e, connected with the tightening-rollers F and F", the two sets of cords constituting two independent supports for different grades ofcarpets, and the whips of the cylinder being adapted to pass between the upper series of cords to the lower series, substantially in the manner and for the purpose described.

3. The combination of the frameA with the sliding frame B and hinged frame 0, having carpet-supporting strips or cords, substantially 25 as described.

4. The combination, with the horizontallymovable frame B, of the swinging frame G. hinged thereto and provided with attached cords to support the carpet, and a swinging 0 support, M, for holding the hinged frame in an inclined position, substantially as described.

5. The combination, with the sliding frame B, hinged frame 0, provided with cords, and a support for holding the hinged frame in an 3 5 inclined position, of the hinged tail-board I and the roller J, on which it rests and slides, substantially as described.
