PETER VAN DEN ESOH, OF STEINWAY, NEIV YORK.

MACHINE FOR FINISHING PLUSH.

SPECIFICATION forming part of Letters Patent N o. `415,009, dated November 12, 1889.

Application led March 6, 1889.

To all whom t may concern:

Be it known that I, PETER VAN DEN ESCH, of Steinway, in the county of Kings and State of New York, a citizen of the Empire of Germany, haveinvented certain lnew and useful Improvements in Machines for Finishing Plush, of which the following is a specification.

This invention relates to an ilnproved machine for finishing plush, so that the same receives a glossy and linished appearance over the entire surface of the raised nap; and the invention consists of a machine for finishing plush, composed of a number of driving and guiding rollers supported on a suitable frame, a rotary beating device for the plush at one end of the frame, an atomizer for applying the size by which the gloss is imparted to plush, said atomizer being located adjacent to said beating device, a number of brushrolls and intermediate supporting-rollers, a guide-drum, and a heating device below said drum for drying the plush and imparting luster to the same, said drum around which the plush passes being readily lifted by ymeans of a hand-lever arrangement whenever a seam passes between the drum and heating device.

The invention consists, further, of certain details in the construction of the machine, which will be fully described, and finally pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of my improved machine for finishing plush. Figs. 2, 3, and 4t are respectively a partial elevation, a partial horizontal section, and a vertical transverse section of the atomizer, by which the size is applied to the nap of the plush. Fig. 5 is a side elevation of the heating device for drying the plush. Fig. 6 is an end elevation of the same, and Fig. 7 is a vertical longitudinal section of the heating device on line y y of Fig. 6 on aflarger scale. Fig. 8 is a transverse section, partly in elevation, on line x x of Fig. 5, on a larger scale.

Similar letters of reference indicate corresponding parts. i

' Referring to the drawings, A represents the supporting-frame of myimproved machine for finishing plush, which frame is provided at one end with a number of tension-rods cay Serial No. 302,154. (No model.)

and a guide-roller l), over which the fabric is passed and from which the same is conducted'4 in a longitudinal direction with the nap downward over a number of rotary brushrolls C and under intermediate supportingrolls O', which latter are supported in bearings of standards C2 on a plane above the brush-rollers.

A rotary beater D is disposed at one end `of the machine over the. path of the fabric; As shown, this rotary beater consists of spiderframes d, supported on a shaft d5, and rods d, supported at their opposite ends in said spiderframes. As the beater revolves, the rods d come in contact successively with the back of the plush and impart a quick succession of blows thereto, serving as whips to beat out the dust therein contained. These rodsV or whips dare preferably j ournaled in the spiderframes so that they will rotate axially when in contact with the plush, whereby friction is avoided. The shaft d5 of the beater-frame D is supported in bearings in horizontal brackets d', which are verticallyT adjustable by means of screws d2 on vertical guide-standards d3 of the main frame A, as shown clearly in Fig. l. By adjusting the beater-frame lower or higher in its supporting-standards the beaters or whips exert a greater or less effect on the plush fabric, so as to beat the same more or. less violently, according to the size of the nap and quantity of dust contained in the same. 9

Adjoining the rotary beater-frame D and between the same and the first brush-roll C is arranged an atomizing apparatus E, which is clearly shown in detail in Figs. 2, 3, and 4. The atomizing apparatus E serves the purpose of supplying a suitable size in finely-divided state into the nap of the plush in such a manner that all the fibers of the nap receive some of the size. For this purpose the size is placed in a reservoir E', from which it is conducted by a pipe e, provided with a stopcock e', into a horizontalcylindrical receptacle E2, which is provided at one end with an ordinary water-gage W, for indicating the quantity of size in the same. From the cylindrical receptacle E2 the size passes through a horizontal channel c4 below'the receptacle E2 into a second smaller supply-cylinder E3, from IOC) pipes with tapering nozzles e2 in upward direction, as shown clearly in Eig. 4. Between the larger and smaller cylindrical receptacles E2 E3 is arranged a longitudinal air-tube E, which communicates at both ends by pipes e:3 with a suitable source of supply of compressed air. The air-tube E4 and the sizereceptacle E3 are divided midway by transverse partitions E13 into two halves, and there is a channel et at each end of the atomizer, so that each half can be worked independently of or jointly with the other half.

The atomizing apparatus, as well as the beaters and the brush and supporting rolls, are of such a width that simultaneollsly two widths of plush can be passed over the finishing-machine. In case one piece only is to be linished the air and size supply pipes of the other half of the atomizer are closed, and only that half of the atomizer over which the fabric is passed is called into action. From th e air-supply tube E't extend toward the discharge-nozzles of the size-supply pipes inclined air-pipes e, the nozzles of which are located in vclose proximity to the nozzles of the size-supply pipes, so that the suction exerted by the escaping air lifts the size from the size-supply cylinder E3 and forces the salnein finely-divided spray or vapors against the nap of the plush. The brush-rolls arealternately rotated in opposite directions and serve to work the size thoroughly into the nap, so as to incorporate it with the fibers thereof.

Motion is imparted to the brush-rollsCaud beater-fran1e D from the pulleys of a drivingshaft S, which is supported in bearings at the center of the machine. A cross-belt passes from one of the pulleys on the drivingshaft over pulleys at the ends of 'one-half of the brush-rolls and over a pulley of the beater' frame, while a second belt passes over the pulleys of the remaining brush-rolls, as shown in Fig. l. vlVhen the plush arrives at the opposite end of the machine, it is passed below a guide-drum E of smoothly-polished steel. A gear-wheel m on the shaft of the guidedgum meshes with a pinion n on the shaft o, said shaft being provided with a pulley p, from which a crossed belt q extends to a pulley 9' on the driving-shaft S, these parts or their equivalents constituting the means whereby motion is communicated to the guidealrum in the direction as shown by the arrows in Eig. l. From the guide-drum F the plush passes over a draft-roller G, which is mounted with cards and located at the upper corner of the support-frame A, and which roller receives rotary motion by a crossbelt s from a pulley of the shaft o of the driving-pinion of the guide-drum E. From the driving-roller G the plush passes over a number of intermediate guide-rollers g g to a second card-mounted draft-roller G at the opposite corner of the machine, and from the same over a smaller guide-rollerto a suitable folding device.

The shafts a andi: of the card-mounted rollers G G are provided with pulleys w and w', connected by a belt y, whereby motion is transmitted to roller G.

Below the guide-drum E is located the drying apparatus ll, which is shown in detail in Figs. 5 to 8. The drying apparatus consists of a gas-heated cast-iron box 71 having a horizontal polished top surface, above whiehthe nap of the plush is guided by the drum 'E at such a distance that the nap does not touch the horizontal top surface of theheating-box. A pipe 7L' extendslongitudinally through the heatingbox 71, said pipe beingprovided at its upper part with a number of small jet-holes 7L. Gas is supplied by gas-supply pipes 71,", provided with stopcocks at both ends and at. the middle part of the heating-box 71 said gaspipes terminating in hollow spherical casings 7L, which are provided at that part which surrounds the gas-supply pipes with air-inlet openings 7L, through which a certain quantity of air is drawn in and mixed with the gas, so that the gas and air mixture when emitted through the jet-openings 7b2 of the longitudinal pipe 7L burns with a blue heating-llame on the principle of the Bunsen burner. The additional quantity of air required for the combustion of the gas and air mixture is supplied through the open bottom of the heating-box 7L, while the products of combustion are conveyed to the outside through openings 7LG in the ends and side walls of the heatingbox 7L, which openings are shown respectively, in Figs. 5 and S. The heat radiated from the upper surface of the heatingbox 71j dries the finely-distributed size that has been incorporated into thcnap of the plush, so that a tine luster is imparted to the nap.

The drum E, under which the plush is passed, is supported in bearings in horizontal arms F', which are pivoted upon the shaft o of the drivingpinion n, and supported at their opposite ends on vertically-movable screw-rodsf, which engage threaded sleeves f of the arms E and rest loosely at their lower ends on fixed posts f2. The drum F is vertically adjusted by the screw-posts f, as shown in Fig. l, so that the distance at which the fabric passes from the heating apparatus can be readily adjusted, according to the degree of heat to which the fabric is to be exposed in its passage under the drum.

The machine is provided with means for raising the drum bodily on the approach of a seam in the fabric, consisting of an elbow-lever F2, pivoted in a bearing f3 of the frame. The lower short arm of said lever is provided with a recess in its inner face, in which is disposed an inwardly projecting anti friction roller f5. The trunnion f of the elbow-lever E2 may extend across the machine in the form of a rod and be provided at its opposite end with a short arm corresponding with the short arm of said lever F2. This short arm may also be provided with an anti-friction roller. The anti-friction rollers of the short arms 'roo rest against the under sides of the support-` plush by contact with the heating-surface is prevented. y l

Each piece of plush is passed twice through the machine, t-he second time with its end reversed, so that the nap of the plush receives a splendid luster and finish.

By my improved finishing-machine large quantities of plush can be finished in a uniform, quick, and effective manner at a considerable saving of time and labor, While a superior finish is imparted to the nap, as the operations of beating, sizing, and heating are performed in an automatic and reliable manner.

Having thus described my invention, I claim as newand desire to secure byLetters Patentl. The combination of draft and guiding rollers for the fabric, a rotary beater, an atomizing apparatus adjoining said beater, a number of brush-rolls for incorporating the size into the nap of the plush, and a number of supporting rolls alternating with said brush-rolls, substantially as set forth.

2. The combination of a supporting-frame having draft and guiding rollers for the fabric, a rotary beater at one end of the machine, an atomizing apparatus adjoining said beater, a number of rotary brush-rolls arranged below the fabric, a number of alternating supporting-rolls located above the fabric, a guidedrum at the opposite end of the machine, andv a heating apparatus below the guide-drum, substantially as set forth.

3. The combination of a rotary beater, a number of brush-rolls, a number of supporting-rolls alternating with the brush-rolls, and an atomizing apparatus located between the beater and brush-rolls and composed of a horizontal size-supply cylinder having suction-pipes provided with discharge-nozzles, and an air-supply pipe having inclined airdischarge pipes Whose nozzles terminate above the nozzles of the size-supply pipes, substantially as set forth.

4. The combination, with a guide-drum, of a heating apparatus located below said drum, therheating apparatus being composed of a cast-metal heating-box provided with a longitudinal pipe having j et-openings, and gas and air mixers communicating with said pipe for supplying the mixture of gas and air for heating the boX, substantially as set forth.

5. The combination of a supporting-frame having draft and guiding rollers for the fabric, a heating apparatus, pivoted arms, a guide-drum supported in said arms above the heating apparatus, and a fulcrumed elbowlever adapted to engage said arms for lifting the drum.

6. The combination, with a supportingframehaving draft and guiding rollers for the fabric, of a heating apparatus, al guidedrum above the heating apparatus, and means for vertically adjusting said drum, substantially as set forth.
