MACHINE FOR DYEING FABRICS.

SPECIFICATION forming part of Letters Patent N 0. 468,579, dated February 9, 1892. Application filed August 3, 1891. Serial No. 401,469. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM M. ROBERT- SON, a subject of the Queen of Great Britain, residing at Newark, Essex county, and State of New Jersey, have invented certain newand useful Improvements in Machines for Dyeing Fabrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a simple and reliable dyeing and bleaching apparatus, cheap in construction, and easily handled and operated.

The invention consists of the improved d yeing apparatus, generally applicable for dyeing, scouring, bleaching, mordanting, steaming, washing, or otherwise treating yarns of cotton, wool, silk, or any animal or vegetable fiber; a perforated drum divided into three or more compartments or sections and adapted to be revolved; of a dye-tank and means for raising or lowering said dye-tank, and of the arrangement and combination of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several figures, Figure 1 is a front elevation of my improved dyeing apparatus. Fig. 2 is a side elevation thereof. Figs. 3 and at are enlarged detail views of the dyeing-drum. Fig.5 is an enlarged detail view of the elevator-shifting mechanism. Fig. 6 is a sectional view on line at, Fig. 5 and Fig. 7 is a detail view of the elevator-stopping mechanism.

In said drawings, a represents the dyeing drum, adapted to revolve with shaft 12, said shaft resting in bearings c c on top of framework A A, the latter being secured to the floor or to any suitable foundation P. The dyeing-drum consists of the two side plates ct a with openings a having on their inner sides circular grooved projections a a in which tit metallic rings a a The outer tion.

ring a is provided with a great number of small openings a a and the inner ring a with slots a running parallel or diagonal with the shaft. The space between the two rings or cylinders is divided by perforated plates (t a into three or more compartments, each of these compartments having one or more doors a secured to one of the side plates a, and thus covering openings a a" in said side plate.

A drum or cover B is arranged around the dyeing-drum to prevent the escape and consequent waste of the dyeing-liquid. This cover consists of three sections B B B and is held in position by rods D D, secured to the frame A A. The sections B B are secured by hinges to section B and are adapted to be turned on said hinges, thus giving room for the doors a to be opened.

Between the frame A A and underneath the dyeing-drum is arranged the tank carrier or table f, provided with rails f and adapted to be raised and lowered by screw g in guides A A. Said screw 9 works in a threaded hub h of gear-wheel h, which latter is operated by connecting-shaft 1' through transmitting gear-wheels k Z 171.. The conmeeting-shaft 'i is provided on its top end with a beveled gear-wheel '6, adapted to mesh into beveled gear-wheels b or b which are secured to shaft 1). This shaft 01 revolves in bearings t i adapted to slide in elongated slots 0 o in brackets o 0. The upper bearing t is provided with a pin 17, Working in a slot 0 of bracket 0. Tosaid pin 1) is secured a hand-lever q, pivoted at q and provided on its free end with pins q. (Shown in Figs. 1, 5, and 7.) When the lever q is moved to the right or left, the pins (1 g catch on projections r r on lever s. Said lever s is pivoted at s to frame A, Figs. 1 and 5, and is, with the shorter arm, pivotally connected to rod t with stops if and The springs u it hold the lever q in normal position. To the table f is also secured a pin i adapted to engage with stops t and i when the table is raised to its extreme height or lowered to its normal position. The tank or vat H holds the dyeing-liquid and steam-pipe K heats the said liquid when the apparatus is in opera- The power is transmitted to the shaft through pulleys N and N and is regulated by a brake-wheel M.

The operation of the machine is as follows: The yarn or cotton is placed in the dyeing drum a, the doors a a are closed, and the covers B B brought into normal position. Power is then applied to the large pulley N and the lever q is moved to the right, thus bringingt-he beveled gear-wheel z" of connecting-shaft z'into mesh with beveled gear-wheel b on shaft b. By the gear-wheels 7c, Z, m, and h the table carrying the tank or vat is raised until pint of table f engages pin 25 of rod 1, which releases the pin (1 of lever g from projection r of lever s, and by the action of the springs to u the lever q is brought back to its normal position, as shown in Fig. 1, thus disconnecting the beveled gear-wheels 1) and Z). By the screw g the table and the tank or vat are brought upto the position as shown in dotted lines in Fig. 2. The dyeing-drum is slowly revolved, with about one-third of its diameter immersed in the dyeing-liquid, until the yarn or cotton is thoroughly saturated. Then the lever q is moved to the left, thereby connecting beveled gear-wheels z" with 19 and by means of the screw 9 the table, with itstank or vat, is lowered until pin i engages with pin t of rod t, which releases the lever q, with its ping fromprojiection r, thus disconnecting the beveled gears t" and b and bringing the table with its tank or vat to rest. The belt is then shifted to the smaller pull-y N, which revolves shaft b with dyeing-drum a at ah'igh speed, and all the surplus dyeing-liquid is thereby thrown through the perforations of the outer ring of drum 0/ against the inner wallof cover B and drops back into the tank or vat. Vhen the tank or vat is at its extreme height, steam is applied to steam-pipe 70, thus heating the dyeing-liquid to any degree desired. After sufficient time has elapsed the drum is stopped and the yarn or cotton removed, which by the centrifugal force exerted is thoroughly dyed and perfectly dry.

I do not intend to-limit myself to theexact construction shown and described, as various changes can be made without changing the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A dyeing apparatus consistingof adrum secured. to a shaft, said drum having an outer perforated and an inner slotted ring, side plates holding said rings tbgether, perforated partitionplates between said rings forming compartments for the fabric, a tank or vat for the dyeing-liquid, a table carrying said tank or vat,.and a mechanism for raising and lowering said table, all said parts being combined and adapted to operate substantially as described, and for the purposes set forth.
