SPECIFICATION forming part of LettersPatent No. 251,806, dated January 3, 1882. l

' Application tiled Noveluberll, 188.1. (No model.) u

Tocll whom 'it may concern: i

Be it known that I, AUGUSTUS PL STEVENS,

of' Brooklyn, Kngscounty, New York,havein t vented Improvements in the Constructionof Carpet-Cleaning Machines 5 and I do hereby `declare that the following is a full, clear, and

correctde'scription of'the same,referencebein g had to the accompanying drawings, making part of this specification, and to theletters of Inthedrawings `like parts of the invention arepointed out bythe samcletters of reference.

The nature of the present invention consists in improvements in the construction of carpetcleaning machines, as more fully hereinafter i set forth, and `will be found to relate more particularly to the construction of the beaters and the means to operate them, and to the means employed to collect (so to speak) the dust beaten from the carpet and to dispose ofthe samepthe object of the invention being the production of a machine for cleaning carpets thoroughly and with the least possible wear to the carpet cleaned.

To enable those skilled in the arts to make and use my invention, I will describe its coustruction and operation.

A is a frame-work, made preferably of wood, andformed by boltin g together the sections composing it, for supporting the operative parts of the machine.

B are boxes secured upon the cross-braces O of the fratrie-work, within which are received the ends of the rotating recil'irocating shafts D, upon which are attached the beaters E, usually formed from cane, rattan, or other suitable material. These beaters E are curved and held upon the shafts D, and are placed a short distance from each other. Within the outer beaters, E, are placed the smaller 4beaters E2. When placed in the frame A the shafts D are `so positioned that the beaters Eand E2 upon one of the shafts D shall be above one shaft, lwhile the beaters E and E2 shall be below the other shaft.

to thebeaters E and E2. Hand Hz'fare pulleyssecured uponv the ends ofthe shafts D, and I is a pulley secured upon one end of the shaft F. Over the pulley I is `passed a belt, J, the ends of which are secured lupon` the pulleys H and H2; and K are belts the ends of which are attached tothe pulleys `H and H2L and the quadrantal plate L, hung upon `a stud secured inone ofthe Acrossbraces O, about midway-between the pulleys Il and H2. To the center of this quadran tal plate vL is piv- Iotedone end of a pitma-n, M, the opposite end of which is fastened to a crank-arm, N, secured upon a revolving shaft, O, having its bearing in theboxes P, supported by the auxiliary framework A2:

Upon each side of the rock-shaft E, and havingtheir bearings in the frame-work A, are the spiral-shaped brushes Q, upon theends of which are securedl the pulleys It, and upon the opposite Aend of one the pulley S.

At the bottom of the frame-Work A, having their bearin gs in the boxes T, are the revolving shafts U, upon one of which the carpet to be cleaned is wound, and upon the other of which the carpet is Wound after it has been passed through the machine and been submitted to the action of the'bcaters. These shaftsU may be driven, as in the present instance, by a system of gearing, V, W, and X, or by arseriesof belts; but as they form no essential feature of the present invention, being only intended to receive and allow the carpet to be properly presented to the action of the beaters and spiral brushes, actin g indirectly, I do not consider it necessary to describe their construction-in de- 4to the frame A, and have a spiral spring, Q2,

attached at one end to the under side of the brake, its opposite end being attached to the base supporting the frame-work A.

The frame-Work A is provided with a series of bands or belts, a, extending from the upper cross-brace to the lower cross-brace, the object of which is to form a baeking,7 so to speak, for the ca rpet, that it may receive the full force of the blows imparted to it by the beatersE and E2.

Over the pulley S upon one of the brushes Q, and a pulley, 3, upon a shaft, 4, in the auxiliary frame-Work A2, is passed a belt, 5, and over the pulleys 6 and 7 the belt 8 is passed, and thus motion is given to the brushes Q,which are intended to be driven at a very high rate of speed.

Such being the construction, the operation will be readily understood: The carpet to be cleaned is attachedat one end to one of the shafts U, upon which it is wound, and its opposite end is attached tothe other shaft U, upon which, after itis passed through the machine, it is wound. The carpet is slowly unwound from one of these shafts, is passed through the machine upon the inside of the cords or strings a, and over the rollers 9, in line with the rotating reciprocating shafts D, and in its passage through the machine is beaten upon its under side by thebeaters E E2, held upon the rota ting reciprocating` shafts D, and the beaters G G2, secured upon the shaft F.

It will be seen that the beaters are operated by the quadrantal plate L, being connected to it, as described heretofore, and that this quadrantal plate L in turn derives its movement, through the pitman M and crank N, from the shaft O, driven by hand or otherwise. As the carpetpasses through the machine and is beaten by the beaters the spiral brushes Q, placed upon the opposite side of the carpet and running at a high rate of speed, suck up the dust, lint, yor other matter beaten from the carpet, which is carried 0E to the chimney or flue over the machine.

In the use of the invention two points of special interest will be noted: First, the carpet is beaten on the back or warp, and, second, the brushes Q are not brought to bear upon the face of the carpet-,thus wearing the saine, but move rapidly over it and suck up the dust morethoroughly than if brought in contact with the carpet.

The carpet cleaned as described is less liable to be injured or destroyed than in machines as usually constructed.

Having now set forth my invention, what I claim as new isfy 1. In a carpet-cleaning machine, the combination, with suitable means for passing the carpet through the maehine,.of the shafts D, carryin g the beaters E and E2, the shaft F, provided with the beaters G and G2, and a quadrantal plate, L, connected to the shafts D and F, as shown, and operated by the pitman M, crank N, and driving-shaft O, when the same shall be constructed and operate substantially as and for the purposes set forth.

2. In a carpet-cleaning machine, the combination, with suitable means for passin g the carpet through the machine, of the spiralbrushes Q and the shafts D. carrying the beaters ll and E2, and the shaft F, provided With the beaters G and G2, and a quadrantal plate, L, connected to the shafts D and F, as shown, and operated by a pitman,M, crank N, and driving-shaft O,

when the same shall be constructed and oper-v ate substantially as and for the purposes set forth.
