APPARATUS FOR TREATING TEXTILE MATERIAL IN LENGTHS.

Specification of Letters Patent.

Application filed May 23, 1910. Serial No. 562,851.

the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This lnvention relates to apparatus for treating textile material in lengths, and is an improvement upon the constructions shown in my Patents No. 408,388, August 6, 1899, and No. 653,485, July 10, 1900.

In order that the principle of the invention may readily be understood, I have disclosed certain embodiments thereof in the accompanying drawings, Wherein Figure 1 is a view, partially in side elevation and partially in vertical section, of an apparatus embodying my invention; Fig. 2 is a view, partially in front elevation and partially in vertical section, of the apparatus shown in Fig. 1; Fig. 3 is a transverse section upon the line 33 in Fig. 1; Fig. 4 is aView similar to Fig. 1 of a slightly modified form of my invention; Fig. 5 is a plan View of the upper end of the apparatus shown in Fig. 4; Figs. 6 and 7 are vertical sections of the lower ends of slightly modified forms of my invention; Fig. 8 is a vertical section of a still further modified form of my invention; and Fig. 9 is a plan view of the construction shown in Fig. 8.

As shown in my patents above referred to, textile material in lengths, such, for example, as cloth or yarn, has been iled or folded into the open, upper ends of J or U shaped chutes, the material being treated either prior to or during its passage through said chute to the action of some suitable liquor, such for example as a bleaching, dyeing or other conditioning liquor. Asdisclosed in said Patent, No. 408,388, the front and rear Walls of said chute were made of power driven aprons to facilitate the passage of the material therethrough. As shown in said Patent No. 653,485, I have facilitated the passage of the material through the chute by maintaining a flow of liquid suflicient to float the material therethrough.

In the present application, I disclose improved andsimplified means for facilitating the passage of the material through the chute and in such manner as to prevent tangling of the material and to result in the discharge of'the material in folds preferably extending transversely of the chute and substantially normal to the walls thereof. In other words, the material is discharged without entangling or binding. a

Referring more particularly to the drawings, I have therein shown a chute having an upturned material intake end 1. The material is delivered into the chute in any suitable manner, but preferably it is folded or piled therein by suitable feeding mechanism arranged to move to and fro above the in-take end of the chute. In Figs. 1 and 2, I have indicated suitable mechanism for this purpose and intended more particularly for delivering goods in arrow or rope like form, and consisting of a pot eye 2, to which said material is delivered, saidpot eye being mounted for to and fro movement upon a threaded shaft 3 mounted in suitable brackets and provided with suitable reversing mechanism, not herein necessary to illustrate. Mounted adjacent said pot eye 2 are rolls 4, 5, geared together as shown and driven by a pulley 6 from any suitable source of power. The threaded shaft 3 is shown as driven from the roll 4 by sprocket chains 7 Below the rolls 4, 5 is a feeding member 8 suspended for to and fro movement by arms 9 suitably pivoted to the frame -work. Suitably mounted in hangers is a sprocket gear 10 driven by sprocket chain 11 from the roll 5 and coaxial with the gear 10 are sprocket pinions 12, which drive through the sprocket chains 13 sprocket gears 14. Suitably attached to the sprocket chains 13 and. to the feeding member 8 are a pair of links, of which one is shown at 15.

It will be apparentthat upon the rotation of the gears 10 and 12 the sprocket chains 13 are continuously driven in one direction, so as to impart through the'links 15 a to and fro movement tothe feeding member 8, as indicated in dotted lines. Owing to the fact that the gears 14 are of larger diameter than the pinions 12 the feeding member 14 Patented, Get. a, rare.

moves relatively slower when at and near the rear wall of the chute 1; that is to say,

when in substantially the position indicated Q The resultof this operation greater degree at the rear wall of the chute than at the front wall thereof. Any other suitable means for feeding the material to the chute may be employed. i

The material in-take end of the chute is preferably substantially u right. and the material is piled or folde therein as described and is gradually delivered through,

, the chute. The chute is provided with a forwardly extending discharge portion in dicated by the bracket 16 in Fig. 1, said discharge portion terminating in a delivery mouth at substantially the dotted line A in said figure. The rear wall of the upturned material in-take end of the chute 1s indicated at 17 and the front wall at 18 The" ably impervious to the action of the bleaching, dyeing or other liquor, such, for example, as cement or porcelain. If desired, the rear wall 1 of the upturned material intake end ma be of the same or similar material, and or convenience of construction the side walls 21-21 may be of the same material and preferably integral therewith,

as indicated in Fig. 3. If desired, the said rear and side walls may be; vertically grooved, as indicated at 22, for the downward flow of the treatin liquor, which may be introduced through t e pipe 23 near the upper I end of the chute as indlcated in he discharge end of the chute may be formed in or'as a ortion of the base member or part 24. The elivery mouth of the discharge end terminates at substantially the dotted line A in- Fig. 1, and beyond that point the base 2 1 may be-of any suitable shape. It is here shown as upwardly curved or inclined as at 25 insubstantial continuation of the bottom wall 16 of the discharge end. The discharge end may be of gradually increasing diameter in the direction of the onward movement of the material through the chute in order to facilitate its delivery. In the construction shown in Fig. 1, the said discharge end is shown as increasing somewhat in cross sectional area adjacent the delivery month. For convenience of construction, and because it is desirable to construct this portion of the apparatus of material impervious tothe treating liquors, the inner surface of the base portion 24 beyond the line A of the delivery mouth is preferably of cement.

The member 20 is'herein shown as a roll l mounted to turn upon a spindle 26 when suflicient weight of material to be treated has accumulated in folds upon the former 27 extending laterally therefrom substantially normal to the walls of the chute and so as substantially to close the lower end thereof and receive the material as deposited thereon. The said roll 20 is provided with a weight 28 acting at the commencement of the feeding operation to elevate the former 27 in the chute to yield as the material accumulates upon the former in folds. The roll 20 rotates slowly during the accumulation of the material upon the former 27 until the face 29 of the weight 28 contacts with the lower portion 30 of the front wall of the chute, thereby preventing further rotative movement of the roll 20. When the weight 28 has reached the point indicated, the former 27 has sufficiently cleared the bottom of the chute to permit the material being drawn thereunder. It will therefore be apparent that when suflicient material has accumulated in the chute to move the former 27 'into the forward position described, thereafter and throughout the introduction of the material into the chute and its movement therethrough the said roll 20 becomes a fixed or stationary member. In other words, the roll rotates only during the initial use of the chute. The surface of said roll 20. is preferably of wood, and in any event is of a material presenting greater frictional resistance to the onward movement of the material under treatment through the chute than does the opposite or rear and bottom walls 17, 19. i

It will be apparent that the material accumulates upon the former 27 in'folds extending substantially normal to the walls 17, 18, 1 the folded edges of the material preferably contacting with both walls. As the roll 20 rotates, owing to the weight of the material upon the former 27, the said substantially normal position of the folds of the material 1 with respect to the walls of the chute is maintained, owing first to the action of the former27, and after the saidformer has passed beyond the line A at the delivery mouth of the chute, then by reason of the fact that the rear and bottom wall ofv the chute presents less frictional resistance to the onward movement of the material than' does the now stationary front and upper 1 wall constituted by the roll 20. 3

It will be evident that the length of the rear and bottom wall between the in-take end and the line A of the delivery mouth is greater than the length between the same points of the front and top wall, and if both walls presented the same frictional resistance to the onward movement. of the material. then the material would become displaced from the folded condition substantially normal to the walls as described and would be- I come gradually tangled and packed in the chute. The said greater length of the rear and bottom wall of the chute is compensated for by the fact that it opposes less frictional resistance to the material contacting therewith than does the front and top wall of the chute. It will be apparent that particularly in the curved portion of the chute, the weight of the material accumulates more and more upon the rear and bottom wall until finally the entire weight is borne thereby. This increases the frictional resistance opposed to the onward movement of the material, and it is therefore important that this rear and bottom wall present relatively less frictional resistance than the said top wall. In this embodiment of the invention, this eifect is secured in a simple manner by forming said wall of anti-friction material as previously described. Within the scope of my invention, the said rear and bottom wall might be a non-driven surface movable, however, under the Weight and onward movement of the material. I prefer, however, to accomplish the same result more satisfactorily and at less expense by rendering the wall stationary and making it of a suitable anti-friction material.

The front wall 18 of the chute may 'be of any suitable material and is preferably of wood. If desired, and as shown, it may be provided with a transparent pane 31 permitting observation of the material within the chute. As previously stated the material may be treated prior to its admission into the chute and may be withdrawn therefrom .at any desired rate, or, on the other hand, I

may introduce the treating material as through the pipe 23 and withdraw it from the lower end of the chute in any suitable manner, not herein indicated.

The material is preferably drawn through the chute in some positive manner, as, for example, by the squeeze rolls 32, 33, the upper one of which is provided with a weighted arm 34. One or both of these rolls is driven by means of the sprocket chain 35 carried by the sprocket gear 36 co-axial with the driving pulley 6. If desired,-I may provide between the delivery mouth and said squeeze rolls, guide rolls '37, 38, adjacent which may be provided transverse guards 39 to prevent any tangles in the material which may possiblyoccur, from falling back into the base portion of the chute. If desired, adjacent said squeeze rolls I may provide a pot eye 40.

In Figs. 4 and 5, I have shown aslightly modified form of my invention. Therein I have provided an upright pipe 41 terminating in a transverse portion 42 having a number of discharge jet orifices 43, whereby the treating liquor may be introduced into the upper end of the chute. The said liquor,

.after percolating through the material and reaching the bottom of the chute, is discharged through a pipe 44 into the lower end of the pipe 41, where it meets a steam iet introduced through the pipe 45, thereby forcing said treating liquor to return through the pipe 41 and to be re-discharged into the open upper end of the chute. Otherwise the construction of the chute is substantially the same as that indicated-in Figs. 1 and 2.

In Fig. 6, I have indicated still another slightly modified form of my invention, and wherein I have omitted the former and have provided a roll 46 normally stationary. The surface of this roll isof wood and possesses the same frictional resistance to the onward movement of the material through the chute as does the construction described in Fig. 1. If, however, the material should for some reason become packed and entangled in .the chute, the said roll .46 may move slightly from time to time to facilitate the discharge thereof. After the discharge of the packed material, the roll again becomes and is normally stationary for the purpose stated.

In Fig. 7, I have indicated a still further modified form of my invention, wherein the roll is replaced by a fixed wall or surface 47.

This surface is preferably of wood or some equivalent material presenting greater frictional resistance to the onward movement of the material under treatment than does the I opposite wall. For convenience of construction, the portion 48 of the chute exterior to said wall 47, may be of the same material 190 as the base of the chute. For the purpose of the invention, however, the surface 47 should be of wood or some equivalent material.

It will be apparent viewing Figs. 4, 6 and 7, that the lower portion of the chute is of gradually increasing cross sectional area in the direction of the movement of the material through the chute.

In Figs. 8 and 9, I have indicated still another form of my invention. Thereinl have provided a chute composed of a suitable number of sections 49, 50,51 suitably connected and of graduall increasing cross sectional area, as more 0 early indicated in .Fig. 9. The entire inner surface of said chute, and in fact the entire chute, may be formed of some suitable anti-friction material, such .as cement or porcelain, but in this case the front or upper wall of the chute should be faced upon its inner surface with some suitable frictional material, such as wood, as'indicated at 52. In this case the rear and bottom Walls of the sections 50, 51 present less frictional resistance to the material than does the facing 52, so that the 1 25* material is delivered in the manner hereto fore described. If desired, treating. liquor may beintroduced into the chute shown in, Fig. 8, in any suitable manner, and means may be provided similar to that shown in Fig. 1, for folding material therein and for Withdrawing it therefrom.

It will be apparent from the foregoing description that I have provided an inexpensive yet effective means for treating textile material in lengths and have so constructed the chute that the material is delivered thereto without substantial tangling or un due packing, owing to the difference in the frictional resistance presented to the onward movement of the material by the opposite wall of the chute.
