JOHN G. HASLAM, OF PHILADELPHIA, PENNSYLVANIA.

APPARATUS FOR DY E|NG.

SPECIFICATION forming part of Letters Patent No. 505,984, dated October 3, 1893.

Application filed September 26, 1892. Serial No. 446,860. (No model.) i v To all whom it may concern.-

Be it known that I, J OHN G. HASLAM, of the city and county of Philadelphia and State of Pennsylvania, have invented an Improvement in Dyeing-Machines, of which the following is a specification.

My invention relates to yarn dyeing machines and consists of certain improvements,

which are fully set forth in the following specification, and are shown in the accompanying drawings which form a part thereof.

More particularly my invention relates to dyeing machines of the character shown in Letters Patent No. 397,48l,dated the 5th day of February, 1889, and granted to Thomas Wolstenholme, in which a yarn carrying frame is suspended in a dye Vat by lifting devices (by which it may be raised from the vat or inserted therein), and is combined with mechanism for reciprocating it in the dye liquor for the purpose of subjecting the yarn to the proper action of the liquor. With the apparatus shown in that patent it is necessary to disconnect the yarn frame from the lifting devices, to permit it to be reciprocated iu the liquor. In my improved apparatus this disconnection is unnecessary as the yarn frame is so supported by the lifting devices, that it may be reciprocated therein without disconnection.

My inventionalso includes improvements in the devices for reciprocating the yarn frame to move the yarn through the liquor, and embraces automatic locking devices upon the reciprocating arms or levers by which the yarn frame may be automatically locked in the arms or levers, when it is lowered into the vat.

Another improvement relates to the construction of the yarn frame, and to supports for the yarn sticks and embraces improved devices for adjusting the supports for the yarn sticks, to bring the sets of sticks nearer together or farther apart to suit the size of the skeins. In the Wolstenholme patent referred to the adjustment of the yarn sticks is accomplished by the movement of the supports for the lower set of sticks. The adj ustinent can consequently be made only when the yarn carrying frame is lifted from the liquor. By my improved construction, I accomplish the adjustment through the supports for the upper set of yarn sticks, so that A it may be accomplished from the top of the yarn frame, and While the frame is lowered in the vat and the yarn submerged in the liquor.

Another feature of my invention consists of the employment of indicating devices, by which the number of reciprocations that have been imparted to the yarn frame is indicated, so that the attendant or operator is notified when the yarn has been sufficiently worked in the liquor.

My invention also relates to other improvements of construction and arrangements of parts which are hereinafter fully described and particularly set forth in the claims.

I shall now refer to the drawings for the purpose of describing the construction and mode of operation of my improved dyeing machine.

Figure 1 is an end elevation of my improved dyeing machine. Fig. 2 is a longitudinal ver tical sectional view of the same on the line 12 of Fig. 1. Fig. 3 is a transverse vertical sectional view of the same on the line 3-4 of Fig. 2. Fig. 4 is a horizontal sectional view on the line 5-6 of Fig. 1. Fig. 5 is a plan View of the end of one of the levers which support and reciprocate the yarn carrying frame. Fig. 6isa side elevation of the same. Fig. 7 is a vertical sectional view on the line 7-8 of Fig. 2, showing the support of the 'yarn carrying frame on an enlarged scale.

Fig. 8 is a detail view illustrating a modification of the devices for adjusting the yarn sticks. Fig. 9 is a detail view of one of the supports of the yarn sticks, and Fig. 10 is a perspective view of the support of the yarn carrying frame.

' A is the vat, which may be of any convenient shape and construction.

B is the yarn carrying frame preferably of a rectangular shape. This yarn carrying frame is preferably constructed of the uprights B connected at the top and bottom by the end cross pieces B B and B B The lower cross pieces B B I prefer to use as the supports for the lower set of yarn sticks.

B B are longitudinal rods connecting the lower cross pieces B B 7 D, D are the supports for the upper set of yarn sticks carried upon the end uprights B B, and for purposes of adjustment, I prefer to make these supports D movable upon the uprights B, B. For this purpose I prefer to employ the rods D, D, carried by the end pieces B B and extending up through the longitudinal piece 0, with adjusting nuts D upon the ends of the rods D D, provided with internal screw threads, engaging the threaded ends 61 of the rods D. By this means it is apparent that the supports D, D, may be raised or lowered upon the uprights B B, and may thus be adjusted with reference to the lower supports B B to suit the length of the skeins of yarn to be treated. The supports D, D, may be connected with the rods D D by braces d d for the purpose of more firmly supporting them.

E are the upper yarn sticks carried by the supports D, D, and F are the lower yarn sticks carried by the supports B B It will be seen that the adjustment of the yarn sticks is accomplished from the top of the yarn frame by moving the upper supports D, D, so that the adjustment may be accomplished without lifting the frame from the vat; and through the upwardly extending rods carried by the supports D, D, the adjustment may be made even when the frame is submerged in the vat.

For the purpose of permitting the yarn sticks to be easily inserted in their respective supports, and to be readily removed therefrom, I prefer to form each support with a series of sockets a, open at their ends to permit a longitudinal movement of the end of the yarn stick in the socket so that they may be easily inserted and removed.

E is a longitudinal locking bar carried by the supports D, D, and B B extending over and closing the open ends of the sockets e, and supported by supportsf. To insert or remove the yarn sticks, the locking bar E is withdrawn when the sticks may be moved longitudinally to free the ends from the sockets e, or to insert them therein. The locking bar E when in place, looks the, ends of the yarn sticks in their sockets. To prevent the skeins adjacent to the ends of the sticks becoming entangled in the sockets e, the sockets may be provided with a projecting guard e.

For raising or lowering the yarn carrying frame to immerse it in the dye liquor and to lift it therefrom, I employ a cylinder G provided With a piston, which may be operated by gas, air, steam, or water, and is provided with a piston rod H, connected with the yarn carrying frame B. The cylinder G is connected as at g with the pipe I, J, through which the gas, air, or steam or water may be fed to the cylinder or discharged from it to raise and lower the piston in the well known manner. The supply and discharge of the water are. controlled by the valve h. The cylinder Gr may be suspended or suitably supported from the Wall or ceiling but to permit the yarn carrying frame B to be moved away from the vat A, when it has been lifted from it, I prefer to connect the cylinder G with a movable trolley or carriage 1, running on a guide or track I and to make a portion of the pipe I, as J, flexible or jointed, so as to permit the movement of the'cylinder. By this means the frame B may be easily moved away from the vat A. It is apparent that,ins ead of being carried by the movable carriage I, the cylinder G might be suspended from a swinging arm or crane.

The frame B may reciprocate independently of the movement of the rod H for the purpose of working the yarn in the liquor. For this purpose I employ an open support ing frame K, carried by the rod H, through which the longitudinal bar 0 of the frame B extends with freedom of vertical movement therein.

The bar 0 is supported upon the lower portion K of the frame K. To permit the bar 0 to be connected with the frame K, or disconnected therefrom, one side K of the frame K may be hinged as at 7c, so that it may be opened out. The hinged portion K may be locked, when closed, in any convenient manner. Forthis purpose 1 have shown a locking dogL pivoted to the hinged portion K and provided upon its two ends with pins Z, which engage recesses m in the ends of the lower portion K of the frame; the hinged portion K being provided with eyes through which the ends of portion K project.

The sides of the frame K constitute guides in which the bar C may move.

The bar 0 may be provided with guides located immediately adjacent to the sides of the frame K, to guide the bar 0 when it is reciprocated within the guides of the frame K.

The frame B is reciprocated by rocking levers M, having notches n which receive trunnions b on the ends of the frame B. To automatically lock the trunnions b in the notches n of the levers M, I employ a weighted dog N pivoted, as at f, to the notched end of each lever M. The weight of the dog N is so disposed that it normally throws the portion 9 between the jaws which form the notch 'IL, so that the party locks the trunnion in the notch. When the trunnion Z) passes be tween the jaws of the notch, it strikes the portion g of the dog N and pushes it aside against the action of its weight; but when the trunnion Z), becomes seated in the notch n, it has passed below the part 9 of the dog I trunnion and looks it in its bearing. By this means the trunnions b of the frame are automatically locked in the notches of the vibrating levers M. I prefer to form the bases of the portions 9 of the dogs N notched or concave as shown, so that any rising of the trunnions bin the notches n and consequent friction against the bases of the parts 9 will not tend to throw the dogs N open and t thus permit the trunnions to slip out of the notches n, but it will rather tend'to throw the portions 9 farther toward the enter one of the jaws which form the notches 'n, and

thus keep the dogs in looking position. To release the trunnions b the dog N may be thrown over in the direction of the arrow in Fig. 6, into the position shown in dotted lines, when the trunnions may pass freely from the notches n, when the frame B is lifted, and so doing will strike the weighted portions of the dogs and throw the dogs back into their normal positions shown in full lines. The levers M are pivoted as at 0, to the vat A at each end, and their outer ends are connected with the eccentric rods 0 operated by eccentrics O and the shaft 0 which is journaled in suitable brackets 19 on the vat A. The shaft O is driven from the gear wheel P, through the friction clutch P feathered on the shaft 0 and operated by the shifting lever P Q is a pinion carried on a stud son a lever R sleeved on the shaft 0 and engaging the teeth of the gear wheel P. The outer end of' the lever B may be adjustably connected as by a bolt and slot, with a lever B pivoted as at r, to the vat A.

Sis a sprocket wheel fastened on the stud s which carries the pinion Q and is driven by the chain S from any convenient source of power. lhe sprocket wheel S, being driven by the chain S rotates the stud and pinion Q, and by the pinion Q the gear Wheel P is rotated, whence power is imparted to the shaft 0 through the friction clutch P. By

this construction the sprocket wheel S may be adjusted to put the proper tension upon the chain S; since the wheel S and pinion Q are carried by the lever B, which may be ad-' during the reciprocation,thus permitting the liquor to penetrate all portions of the yarn equally, and rendering unnecessary the turning of the yarn sticks, as is now generally practiced for the purpose of shifting the yarn. In the machine herein described it is a'simple matter to properly support the skeins so as to permit this movement, by reason of the great ease with which the yarn sticks may be adjusted through the adjusting nuts D A modified form of these devices for adjusting the yarn sticks is shown in Fig.8. In this construction in place of the rods .D', racks D are employed, operated by a pinion D carried in a bracket 01 of the end frame pieces B and locked by a dog 01 By releasing the dog d the pinion D may be turned to raise or lower the frames D.

To indicate the number of reciprocations of the frame B in the liquor and show when the yarn has been subjected sufficiently to the action of the dye liquor, I employ a rotary, ratchet disk T operated by a pawl 25,

through a lever T, and link t, from one of the levers M. The pawl tis carried by the pivoted lever T which is in turn connected with the lever M through the link t, so that upon each vibration of the arm M the pawl will turn the disk T, the extent of one ratchet tooth. A pawl t is employed to prevent backward rotation of the disk T. be provided with a dial face anda stationary finger or index U may be arranged adjacent to it, so as to indicate by the figure upon the dial under the finger or index U the number of reciprocations that have been imparted to the yarn carrying frame. This indicating device maybe further provided with an alarm V, operated byapin orprojection 2; upon the disk T, so that when the disk has been turned a given distance, corresponding with the desired number of reciprocati'ons of the frame B, the pin or projection Q; will strike the alarm and operate it, indicating to the operator that the-yarn has been sufliciently treated, when by shifting the friction clutch P, the further vibration of the arms M, M, may be stopped, and the frame may be lifted from the vat by the lift G, and may be removed and replaced by another frame with fresh yarn. While I prefer the minor details of construction that have been shown Ido not'limit myselfto them, as it is apparent that they may be varied without departing from the invention.

What I claim as new, and desire to secure by Letters Patent, is-' 1. In a dyeing machine the combination of a dye vat, a lift, a yarn frame supported by the lift with freedom of vertical movement with reference thereto, and devices to reciprocate the yarn frame upon the pointat which it is supported by the lift, and 'independently thereof, whereby the yarn frame The disk T may may be raised from the vat or carried thereframeis supportedwith freedom of movement,
