SAMUEL MARDEN, OF NEWTON, ASSIGNOR TO LEWIS B. PORTER, OF WATER- TOWN, MASSACHUSETTS.

STARCHlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 241,554, dated May 17, 1881.

Application filed Augustll, 1880. (Model.)

,To all whom it may concern: Be it known that I, SAMUEL MARDEN, of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Starching-Machine, of which the following is a specification.

My invention relates to an improved starching-m achine. 1 use a large central corrugated or geared roller rotated by a shaft supported i upon a frame. Around this central roller, except at its top part, is a series of small corrugated or geared rollers, whose corrugated or geared surfaces mesh into the corrugated or geared surface of the central roller, Said small 1 5 rollers revolve upon axles or spindles, one end of which is fastened into movable blocks or bearings sliding in slots in wedge-shape pieces resemblingin appearance and arrangement the spokes of a wheel. The said spokes and a rim form the segment of a wheel, which is stationary, supported on either side by legs fastened to the rim, and extend to the platform of the frame. Between the central roller and the small rollers runs a starch-carrier, which also 2 5 passes over band-rollers attached to ears fastened to the rim of the wheel, and a weighted roller, which is set in the pan containing the starch.

in order that others skilled in the art may better understand the nature of my improve. I ment, I will explain the same by reference to. the accompanying drawings, which are made a part of this specification, in which- Figure l is an end view of the corrugated rollers and a vertical section of the pan and the weighted roller as it sits in the pan. Said figure shows also the wedge-shaped pieces or spokes,the slots therein, and the springs which regulate the movable blocks or bearings in said slots, the rim of the segment of the wheel, and the starch-carrier as it appears in operation. 'Fig. 2 is a plan of the machine, and Fig. 3 is a section of a portion of the starchpan, the weighted roller, starch-carrier, and a 5 slotted upright strip in and upon which the weighted roller revolves.

The letter A represents the platform; B, the frame of the machine; 0 G, legs supporting the rim of the wheel; D, the central roller;

E E, &c., the small rollers; F F, &c., the spokes of the segment of the wheel; G, the rim; H H, band-rollers; Lapressure-roller; J, the weighted roller; K, the starch-carrier; L, the shaft driving the rollers; a, to, &c., springs; b b, &c., axles of the small rollers; c 0, cars on the rim G; d d, slotted upright pieces for the'weighted roller J set in the pan; P, the pan containing the starch; c, movable blocks or bearings, into which the ends of the axles or spindles of the small rollers are fastened; and f, a drum, instead of which I may use a crank on the end of the shaft L.

The starch-carrier is'apt to become stretched from use, and thus become loose, so as not to operate well. As an improvement to the op- 6 eration of said carrier, 1 have placed the loaded roller J in the starch-pan, near the bottom' of the pan, as shown in Figs. 1 and 3, and the roller is lettfreely to move up and down,conforming to the tension of the carrier, but al- Ways keeping said carrier taut. l dispense with gear-wheels, and their shafts also, in volving the corrugated rollers, thus largely saving friction and expense of gears, 850.

By em ploy ing a large central roller, 1), and the series of small rollers E E, &c., arranged as shown, 1 have given greater length of space for filling the articles to be starched with starch,

and thus more completely accomplishing the object sought than has been done by any ma- 8o chine'hitherto patented, and this improvement is of great practical consideration.

What I claim as my invention, and desire to secure by Letters Patent, is-

ln a starchingdnachine, the combination of the rollers l), the rollers E, which revolve each upon a spindle having its hearing or support in a yielding and movable block, 6, the bandrollers H and pressure-roller I, the starch-carrier K, the weighted roller J, whereby the ten- 2 sion of the st arch-carrier is kept uniformly taut, and the pan P, for containing the starch, substantially as and for the purpose shown and described.

SAML. MARDEN.
