IMPROVEMENT IN CARPET-BEATERS.

Specification forming part of Letters Patent No. 149,524,, dated April 7, 1874; application filed February 12, 1874.

To all whom it may concern:

Be it known that I, CONRAD Form, of the city, county,.and State of New York, have invented a new and Improved Carpet-Beater; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing Figure 1 represents a front view of my beater. Fig. 2 is a detached plan View of the beating mechanism. Fig. 3 is a transverse vertical section of the same.

Similar letters indicate corresponding parts.

This invention relates to a machine for beatin g carpets, &c., in which said carpets are hung or placed in a vertical position, whereby the particles of dirt or dust are more readily disengaged therefrom by reason of gravitation. My invention consists in the arrangement of a series of horizontally-oscillating' beatingarms on vertical rock-shafts, which are operated by means of elliptical gear, in such a manner that an accelerated motion is imparted to the beating-arms, whereby a thorough and uniform cleaning of the carpet is insured. The

carpet is drawn over an upright flexible bed in the rear of the beating-arms, whence it passes over rotary brushes for removing any adhering dust.

In the drawing, the letter A designates the frame of my machine, which is provided with a dirt-box, A, and on its front side with rails or sills B, forming the step or bearing for a series of vertical beater-shafts, O, which are arranged in rows between two of the sills, each being furnish ed with a series of beating-arms, a. The shafts alternate with each other in position, so that one series of beating-arms works between two others, and that such arms reach over the whole of the surface of the carpet, which is immediately in the rear of the beater-shafts, being supported on a bed, D, composed of cords or ropes, which are stretched across the front of the frame. The

beating-arms are of any suitable form or shape, and may, if desired, be covered with leather or like material, so as not to injure the texture of the carpet in beating. The beater-shafts O are provided on one end with a pinion, b, which is engaged by a reciprocating rack, E, arranged in guides c on the sills. This rack E connects, by means of a crank-arm, F, with one of a pair of horizontal gear-wheels, G, of elliptical form or shape, the other of which wheels receives a rotary motion from a vertical pulley-sh aft, H, which extends from top to bottom of the machine.

By the employment of the elliptical gearing for driving the beater-shafts O, a varying speed or motion is obtained, and an acceleratingtbrce is given to the beating-arms. These beatingarms move through a half-circle, striking the carpet oneach side of the beater or rock shafts to each revolution of the elliptical gear-wheels F; and the speed or force of the beating-arms is greatest as they strike the carpet, relaxing as they recede or rise therefrom, so that no power is wasted or lost in my machine.

The horizontal driving-gear of one row of rock-shafts is placed in a position opposite to that of the other row, so that the blow or stroke of their respective beating-arms is made to alternate.

A rotary brush or sweep, K, Fig. 3, is placed in proximity to one face, and a similar brush, L, in proximity to the other face, of the carpet, these brushes being arranged .on opposite sides of feed-rollers M M, which serve to draw the carpet through the machine. The several brushes and rollers receive a rotary motion from the pulley-shaft H, with which the same are connected in any suit-able manner.

What I claim as new, and desire to secure byLetters Patent, is-

In combination with the shafts 0, having beater-arms a, the elliptical gear-wheels Gr, connecting-rod F, rack E, and pinion b, constructed and arranged to operate substantially as described, for the purpose specified.

This specification signed by me February 2, 18H.
