Application filed November 2, 1883.

To aZZ w/wm it may concern.-

Be it known that I, ALBERT A. BoYnR, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Machines for Cleaning Carpets, of which the following is a specification.

My invention consists of a machine for cleaning carpets which has an adjustable vertical frame carrying a pad for holding the carpet, said frame being heldin its adjusted position on the housings or standing frame by a pair of pawls that engage with toothed racks, in combination with a revolving shaft in front of said pad, carrying beater-straps, whereby a carpet when laid 011 the pad may be advanced to or receded from said beaters, in accommo- I dation to the force of the blows desired to be struck.

The invention also consists in the combination of said carpet-carrying frame with another frame at the lower part of the machine that slides between the housings and guidestrips, said carpet-carrying frame being connected therewith by an upright post at each side, the two frames being so connected that when the lower one is moved inward or outward an angle of any desired degree may be given to the pad holding the carpet, to suit fabrics of different textures.

In the accompanying drawings, which make a part of this specification, Figure 1 is avertical section at the line a m of Fig. 2. Fig. 2 is a plan view of the machine. Fig. 3 is an end elevation of the adjustable bed-frame B and parts attached. Fig. 4. is a face view of a beater-stock, G, and connected parts on an enlarged scale. Fig. 5 is an edge view of the same. Fig. 6 is afacc view of the beater-stock- G alone.

Like letters of reference in all the figures indicate the same parts.

A represents the standing frame of the machine with which the several parts are con nected.

B is an adjustable vertical frame provided with the bed or pad 0, on which the carpet D (seen in Fig. 1) is beaten as it is drawn forward in the direction of the arrow.

E is a revolving shaft with which the beat- (No model.)

ers are connected, having on one end a pulley, F, which is connected by means of a belt with the motive power. The shaft is provided with a series of beater-stocks, G, connected therewith by means of the pivot-bolts a and eyebolts b b,- and H are beater-straps, made of rubber, and connected to the stocks G at one end by means of the thumb-screw pins 0 and openings 0, whereby to provide for an expeditious detachment of Worn-out straps for the connection of new ones, the attachment being easily made by passing the end of a strap and connecting the slot with the head-pin, or the detachment made by removing the strap from the pin and then drawing it through the openlng c.

The beaters are arranged in spiral form, as represented in Fig. 2, to provide for the blows being given continuously, in regular succession. There are gum-straps I, which are arranged on an angle, as shown in Fig. 1, which hold the carpet above the pad 0 until forced down by the blows of the boaters successively, (the upper end being connected to the bar (I, and the lower end to the board 6, which board supports the pad or bed 0,) thereby giving a springing movement to the oarpet,to assist in loosening the dirt.

The frame B is adjustable inward and outward by means of its connection with the horizontal sliding frame B, which rests upon the bottom board, f, of the stationary frame A, being guided by the uprights of the said frame and the guide-strips g g. The lower end of the frame B is seated in bearings of the frame B, and anangular position is given to it by moving the latter frame in or out, to give any required angle to the bed or pad 0, the frame being confined in its adjusted position by means of pins h h, which enter suitable holes in the. board f,- and the said frame B is adjusted at its upper end also by means of the pairs of pawls i 2' and racks J J, it being moved inward or outward, as may be required, to'vary the distance of the pad 0 from the beater-shaft G, in order to vary the length of the blows of the beaters; and hence, by the adjustment of the frame B at its lower end, it may be so arranged as to cause flat blows on heavy carpets and angular blows 011 light carpets, and by the adjustment of its upper end to cause the carpets to receive any desired 3. The metallic stock G, having a head-pin,

length of blows. c, and opening a, in combination with the I claim as my invention beater-strap H, and revolving shaft E, sub- 15 1. In a machine for cleaning carpets, the stantially in the manner and for the purpose 5 adjustable frame B,provided with apad,O, and set forth.
