NITED STATES PATENT OFFICE.

TrTUs S. CHURCH, or BoSToN, MASSACHUSETTS CARPET-BEATING MACHINE.

SPECIFICATION forming part of Letters Patent' No. 302,237, dated J'uly 22, 1884.

Application tiled February 16, 1883. (No model.)

To @ZZ whom it may concern:

Be it known that I, TITUs S.y CHURCH, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Garpet-Beating Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention is an improvement on that Io described in United States Patent No. 262, 004, to which reference may be had, and has more especial reference to a novel manner of attaching the beaters to the revolving cylinder, and to improvements in the construction ofthe carr 5 pet-supporting bed or grid, the invention being hereinafter described, and subsequently particularly pointed out in the claims.

Figure l is a section of my improved carpetbeating machine on the dotted line a: x, Fig. 2; 2c and Fig. 2 is a plan or top viewthereof.

The frame-work A'has suitable bearings to support the journals of the revolving cylinder" This- B, driven by belt in any, usual manner.

cylinder, near each end,A has metal heads or 2 5 collars f, which receive and support the ends of strong metal rods, bars, or cross-pieces e, placednear the surface of the said cylinder, and preferably straddled by staples .2 between adjacent beaters c.

The beaters c will preferably be composed of india-rubber belting about' two and onehalf inches in width, or of a strong broad strap Y of leather, or leather belting, or rawhide. The inner ends of thebeaters, provided with holes or slits, are passed under the rods or cross-pieces and placed over the headed studs, screws, or hooks d, attached to the cylinder,

such method of connection enabling the beat-` ers to be readily detached fromV the cylinder,

4o if desired, or when some of the beaters are not needed, as when beating a narrow carpet. The rods e, extended across but not connected with the beaters, receive the strain of the blow exerted by the beaters on the carpet h, relieve the studs or hooks el of such strain, and also act to keep the inner ends of the beaters from slipping off from the said Studs or hooks. The slots in Vthe beat'ers and the studs or hooks 'd permit the ready attachment or removal of a 5o beater. The bearing-rods, acting on the beaters between their outer ends and their-point of attachment with the cylinder, also act to prevent the free ends of the beaters from falling back and winding about the cylinder as the latter is rotated at high speed. So the em- 5 5 ployment of -the said bearing-rods, bars, `or cross-pieces enables the machine to be practically run at avery much greater speed than were the said rods omitted and the ends of the beaters were attached to the cylinder by 6o nails or screws, and not acted upon between their ends.

The carpet, hto be whipped is moved over the pivoted bed or grid'C,.composed of crosspieces h3, suitable connecting end pieces, and rollers i m, substantially as in the patent referred to. The rods h of the bed are inserted loosely in round holes h2, made in the crosspieces h, the said holes in practice being about seven-eighths of an inch in diameter, and the 7o rods about half that size, so that as the beaters strike the carpet the rods are moved from side to side and up and down, deriving their movement from percussion, and in their j umpin'g movement they act to lift the carpet, and 75 also compel the dust and dirt to fall from them. Placing the rods 7L loosely, as described, in holes in the crossbars of the bed enables them to yield to the blows of the beaters, and so 0bviates tearing the carpet. 8o

l. In a carpet-beating machine, the bedy or grid provided with rods h', set in holes of much larger diameter than said rods, to permit a free movement of said rods under the action of the beaters, substantially as described.

2. The bed and its loosely-held rods h', combined withvthe revolving cylinder and its attached iexible beaters, substantially as described. 9o 3. In a carpet-beating machine, the revolving cylinder and its bearing rods, bars, or cross-pieces extended acrossthe beaters, combined with the flexible beaters, slotted at their ends and passed under the said rods or bars, and removably connected to headed studs or hooks d, attached to the cylinder, substantially as described.

4.. The rotating cylinder, its bearing-rods, flexible beaters extended under the said rods rco and connected with studs or hooks on the said cylinder, combined with the bed provided with the loosely-heid rods h', all substantially as de- 1 In testimony whereof I have signed my name scribed. to this speoioation in thepresence of two sub- 5.
