SPECIFICATION forming part of Letters Patent No. 674,995, dated May 28, 1901. Application filed Pebruary4=, 1901. Serial No. 45,959. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. BISHOP, a citizen of the United States, residing at Chicago, in the countyof Cook and State of Illinois,have in vented certain new and usefulImprovements in Starching-Machines, of which the following is a specification.

One object of this invention is the production ofastarchilig-machine wherein the liquid starch is beaten into the fabric to be starched by means of a rapidly-revolving roller having a peripheral surface other than cylindrical in form. e

A further object of this invention is the production of a starching-machine embodying certain other improvements to be more fully described hereinafter.

In the accompanying drawings, Figure 1 is a side elevation of a starching-machine embodying the 'features of my invention. Fig. 2 is a longitudinal central section through said starching-machine and its supportingframe. Fig. 3 is a plan view of the starching-machine with a portion of the upperapron removed. Fig. et is a plan view, and Fig. 5 a side elevation, of the cradle removed from the starch-receptacle.

Like letters of reference indicate corresponding parts throughout the several views.

In the construction of this starcher I provide the body portion A, having the supporting-legs A therefor. The body portion has a receptacle A2, which latter may be and in practice usually is made double to provide a steam-jacket (not shown) for keeping warm the liquid starch which it is intended to contain. A rigid cradle B is suspended within the starch-receptacle A2. This cradle comprises the side bars B', in double-loop form, the rods B2, extending between said side bars for holding them rigidly together, the guiderollers B2, B4, B5, Bl", B7, and B8, rotatably mounted between the side bars B', and the tension-roller B9, at one extremity of the cradle, for keeping the endless apron, to be later described, at a proper tension'. of this tension-roller are supported within the openings B10 and are capable of a longitudinal movement therein by means of the adjusting-screws B, Each end of the roller B9 is provided with an adjusting-screw, so that either end may be moved independently of The bearings 1 the other. An endless apron B12, made of any suitable material, usually textile fabric, is mounted upon the guide-rollers B3, B4, B5, B6, B7, and BS and the tension-roller B2.

C is a frame adapted to rest upon the cradle B. It supports the rotatable shafts C', C2, and C3, jourualed in the bearings C4, C5, and C, respectively, on opposite sides of said frame C. Each of the bearings CLl is vertically adjustable by means of the hand-wheel C7, the stems of which hand-wheels are screwthreaded and pass through suitable screwthreaded openings in the frame C, an arrangement common in such constructions. The center of the frame C extends upward in the arms CS, carrying between them the roller C9 for supporting an endless apron to be later described herein. At one end of the iframe C, between the arms C10, an adj usting-roller C1l is rotatably mounted. A screw similar to that in the cradle B is provided at each end of said roller for adjusting its position relatively to the body of the frame C, thereby to regulate the tension upon the apron, to be later described. At the opposite end of frame C, in the bearings C12, is rotatably mounted another roller C13. A cylindrical driving-drum C14, mounted upon the shaft C', is adapted to lie adjacent to the guiderollers B4, B5, and B(s in the cradle B. A beater-drum C15, having a peripheral surface other than cylindrical in form, is mounted upon the shaft In this instance I have made this drum with sixteen sides or faces. An endless apron C16, of any suitable material, passes over the adjustable guide-roller C11, thence downward, contacting the apron B12, with' which it passes underneath the drum C14, and between said drum and the three guide-rollers B4,B5, and B6, successively. Still traveling together the aprons C16 and B12 pass upward over the roller B7 and thence downward to the beater-drum C15, the under and rear sides of which are conformed to by both of said aprons for about one-third of the circumference thereof. Leaving the beaterdrurn, the aprons together pass over the roller B8, but here separate, the apron C1G passing upward and over the rollers C13 and C9 to the place of beginning.

A driving pinion D is mounted upon a short shaft D', the outer end of which shaft carries the tight and the loose pulley D2 and D3, respectively. The pinion D meshes with the gear-Wheel D4, mounted upon the shaft C2and this gear-wheel in turn meshes with the pinion D5, rigidly iiXed on the outer end of the shaft C3. The shaft C2 is also provided with the pinion D11. This pinion meshes with a gear-wheel D7, fixed on the outer end of the shaft C. It will thus be seen that the speed of the driving-pulley D2 is geared up in the beater-drum C15 and geared down in the driving-drum C14.

The endless aprons B12 and C1G travel at the saine rate of speed and are in contact and .run over the same rollers from and including the roller B11 and the driving-drum C14 to the guide-rollers B8 and C13. The drivingdrum C14 is adjustable with reference to the rollers B4, B5, and B, so that the aprons are held 'tightly between said rollers and are driven by said driving-drum. The rollers B4, B5, and B6 are grooved more thoroughly to 'knead the starch into the fabric being` passed through the machine between the aprons B12 and C16.

In operation the article to be starched is fed into the machine between the two aprons B12 and C16 and is carried between said aprons downward into the starch-receptacle A2. This receptacle is filled with liquid starch, either hot or cold, as desired. In passing through the receptacle A2 beneath the surface of the starch the article is thoroughly saturated with the liquid as it passes between the drivingdrum C11 and the grooved rollers B1, B5, and BG. The article to be starched is carried between the endless aprons over the guide-roller B7, and from thence the endless aprons B12 and C111 pass beneath the rapidly-revolving beater-drum C15.v Owing to theirregular form of this drum it beats or forces the liquid starch through the apron C16 into the fabric of the article to b'e starched, and as the speed of rotation of said beater-drum is considerably greater than that of the passing aprons B12 and C16 it makes a large number of revolutions while a given point in the apron is passing said drum.

The frame C may be tilted upward at its forward end in ord'er to provide easy access to the interior of the starch-receptacle A2. The tension upon the aprons is regulated in the usual manner by turning the adjustmentscrews therefor. The vertical position of the shaft C is adjusted by means of the hand- Wheels C7.

I claim as my inventionl. In astarching-machine, in combination, a starch-receptacle; two endless aprons; supporting-rollers for said aprons; a drivingdrum for revolving said aprons; a beaterdrum of a form other than round adapted to be rapidly rotated in contact with one of said aprons; and means for driving said beaterdrum at a high rate of rotation.

2. In a starching-machine, in combination, a starch-receptacle; two endless aprons; supporting-rollers for said aprons; a drivingdrum adjacent to certain of said supportingrollers, for revolving said aprons; a beaterdrum mounted so that both of said aprons run over its periphery, which beater-drum is of a form other than round and is adapted to be rapidly rotated in contact with one of said aprons; and means for driving said beaterdrum at a high rate of rotation.

3. In a starching-machine, in combination, a starch-receptacle; a cradle within said receptacle; guiderollers rotatably mounted within said cradle; an endless apron on said guide-rollers; an endless apron lying in contact with said first-mentioned apron; a driving-drum forrevolvingsaid aprons; a beaterdrum of a'forni other than round, adapted to be rapidly rotated in contact with one of said aprons; and means for rotating said driving-drum, and for driving said beaterdrum at a high rate of rotation. 4. In a starchirig-machine, in combination, a body portion having a starch-receptacle; supporting-legs for said body portion; a cradle within said starch-receptacle; guide-rollers rotatably mounted within said cradle; an apron mounted on said guide-rollers; a roller for regulating the tension of said apron; a frame mounted upon said cradle; a drivingdrum rotatably mounted in said frame; a beater-drum of a form other than round, also rotatably mounted in said frame; guide-rollers rotatably mounted in the frame; an apron extending around said driving-drum, said beater-drum, and said guide-rollers; a roller for regulating the tension of said last-inentioned apron; and means for rotating said driving-d rum,for rotating both of said aprons, and for driving said beater-drum at a high .rate of rotation.
