lMPROVEMENTlN MACHINES FORQCLEANIQNG CARPETS.

Specification forming part of Letters Patent No.17 1,727, dated January 4, 1876; application filed November 4, 1875.

To all whom it may concern.-

Be it known that 1, JAMES HOTHERSALL, of

New York, in the State of New York, have cess for the purpose of cleaning the same;-

and, further, in the arrangement of a cord on each side of the machine, directly behind the double beaters, running backward and forward between the frame of the machine, having one of its ends fastened to the frame, and the other end to a tightening-spindle, thus forming an open and elastic back'for the action of the heaters. v

In the accompanying drawing, Figure I represents a front view of my improved machine embodying my invention. Fig. II is a cross section of the same, and Fig. III is an end View, showing the gearing.

Similar letters represent similar parts in all the figures.

To the frame of the machine bars B B B B are arranged, as well as carrying-rollers O and D. The carpet, shown at A, Fig. II, which is fastened together on its two ends, so as to form an endless hand, is passed over those bars B B B B, and between the rollers O and and D, receiving by the action of said rollers a regular motion around the machine. On the side of these rollers the brush-roller E is arranged, below which the carpet is made to pass. On each side of the machine, between the bars B and B,'a cord F is stretched, attached at one end to the frame of the machine,

and then passed backward and forward from one end to the other, over pulleys a, to prevent the wear. and tear of the cord, and fastened at its other end to a spindle, n, provided with a ratchet-wheel and pawl for the purpose of tightening said cord, and to hold the same in the desired tension. In the front of the I cords F, and in the space hetweenthe bars B- B, two or more rows of beaters, G, are arranged, turning in suitable hearings in the frame of the machine. These heaters are placed close to each other, and their arms are so arranged that the arms of one beater pass between the arms of the next beater, and the heaters in the lower row are placed between those of the upper rows in such a manner that the arms of the heaters in this lower row will act against that part of the carpet not acted upon by the arms of the heaters in the upper row. Against the front and back-of the machine bars J are arranged, guided through the rods L L in the end of the machine-frame, and by suitable rollers m. These bars J are arranged with suitable jaws or openings'to allow the ends of the shafts H to pass through, and are provided with frictionrollers 0;, against which cams- K, fast on the ends of the shafts H, are made to act to communicate a reciprocating motion to said bars 'J. Rods N connect these bars J with the arms to attached to the heaters G, and communicate thereby the desired motion to said heaters G. The shafts H H are provided with suitable gearing M M, operated by wheel av fast on the driving-shaft P. On this drivingshaft P a pulley, (1, com mnnicates motion through the band Q to the shaft R, provided with a pinion, 0, operating the wheel S on the end of the brush-roller E, as well as the wheel T on the end of the carrying-roller D. Upon the other end of the roller Da pinion, V, is arranged, meshing into a pinion, W, fast to the roller 0, and. thus communicates the desired motion to the same.

The bars B B have a bottom plate, Y, fitted between them and the ends of the machine to collect the dust beaten out of the carpet, which may be arranged to draw out of one side of the machine for the purpose of emptying the same. The carpet being placed around the bars B B B B, between the rollers O and D, passing under the brush-roller E, and having its ends connected together, forming thus an endless band, as represented in Fig. II, is then in position to be operated upon. Motion being given to the shaft P the several parts will be operated in the manner above de- I scribed. The rollers O and D will gradually e and regularly draw the carpet around the inachine, ijwhich will; then be'brushed while passingnnder the brush-roller E, while that part ofthe carpet hanging straight at the front a and back of the machine, between the bars B B, will be acted upon by the arms of the a y heaters G. i

The gearing Operating these beaters G is so arranged that the heaters in the upper row will act alternately with the heaters in the lower. row. The cord F, stretched from s one end of the machine to the other end, between thebars B and B, backward and forward, will form. an elastic back for the carpet a when acted upon bythe heaters, yielding a slightly at its upper or lower part whenever a the upper orlower heaters act upon the carpet,and, forming thus a perfectly open back, willallow the dust to pass throughand fall upon the bottontplate Y.

WhatI claim as my invention, and desire tosecure by Letters Patent, is-

1 The bars B B, carrying-rollers (J and D,

brush-roller E, and cords F, in combination with double heaters Gr, arranged in relation, with the cordsF onqboth sidesofthe machine,

and operating upon a. carpet connected to gether at its ends, substantially as herein described. a s

2. The cords F stretched between the bars B and B, having one end fastened to the frame, and the other end to a spindle, a, provided with a ratchet-wheeland pawl, in combination with rollers a,in*then1anner and for the purpose substantially as specified. a

3. The combination of cams K, attached to the end of shafts H, bars J, provided with friction-rollers o, rods N, arms 10, and heaters G, substantially as described and set forth. 1

4. The position of the heaters G, alternately to each other in the upper and lower rows, to

act upon different parts of theycarpet, in the manner and for the purpose substantiallyas specified.
