11 Claims.

In patents heretofore granted to me (for eX- ample, No. 1,711,094) I have'disclosed apparatus whereby tubular fabrics, as tubular knit goods, may be progressively subjected to certain treatments, as steaming and drying, with the use of a structure designed to stretch or tenter the fabric as the same is drawn over and encloses said structure and after passing the latter, and so noflonger subject to its action to expand it in substantially all radial directions, is subjected to means enclosed thereby which spreads it to flat-tubular form preparatory to its encountering draft means, as a pair of rollers, by which it is drawn or advanced.

The improvements herein set forth relate to the said draft means and to the means for flat-spreading and control of the fabric after it has passed the mentioned structure, which is usually a steamheated dome, their objects being, generally stated, to provide for adjustment of the draft means, to facilitate the initial entering of the fabric to the draft means, and to avoid the fabric being in certain respects distorted. These objects will be elaborated in more detail hereinafter.

I is a hollow dome having an annular series of fluid outlets la above and below which, respectively, are the flanges 2 and 3, the latter being channeled Vand containing an endless helical spring 4, which coact to form with the tubular fabric a a fluid chamber 5. 6 is the pipe by which iiuid, as steam, is admitted to the dome and l is the condensation eduction pipe. 8 is an annular flange or wall which, with a similar but inverted dished wall 9 above it, may form between them and with the fabric another fluid chamber lil t-o which heated air or other fluid is admitted by the pipe Il partially enclosing pipes 6 and I and carrying wall 8. I2 is a platform on which may be rotatively adjusted a carriage or fabric-support i3 having anti-friction means 13a to travel on the platform.

The fabric to be treated, having preferably first removed the dome for the purpose, is passed over pipe Il and placed on the platform whereupon, the dome being replaced, the fabric is drawn up past the walls 8 and 9, extended between the flange 3 and collar ll and past the flange 2 and the dome and brought into the grip of the draft means as will be described. When the fabric is being treated, as it is drawn upwardly by the draft means, it undergoes diametric stretching or tentering or at least distending by the flange 2 and may be steamed by the steam in chamber 5 and dried by the superadjacent part of the dome, or if it comes to the apparatus in wet or damp condition it may undergo a preliminary drying by warm air admitted to chamber I0 from pipe Il; other treatments are of course possible, depending on the uids used, the presence or absence of heat, and other conditions, and so far as my present invention is concerned all that is actually essential as to the apparatus so far described is that there should be some structure, as the 3 flanged dome, which shall at least distend radially the encompassing and axially moving tubular fabric. While usually the fabric will actually be stretched by the flanged dome, so that any given area thereof would be expanded to greater dimensions than it had prior to the treatment, I do not wish to exclude the mere distension of the fabric to open tubular as distinct from flat tubular form, and by distension I here mean so that any given area would not be expanded to appreciably greater dimensions than it had before treatment.

Fixed supporting structure is afforded by work platform M which carries a pair of standards l5 whose heads form housings I6 containing bearings Il for the cylinders I8 which afford the mentioned draft means, and to that end grip the fabric more or less between them and are driven in the directions of the arrows in Fig. 3. One bearing in each pair is yieldingly urged toward the other by a spring I9 interposedbetween onesuch bearing and a hand-screw 20 tapped into the end of the housing. By means of a cam-block 2| resting on a projection I8@ of one bearing and engaging with a cam-face |819v on the other and a screw 22, tapped in the housing above and bearing upon the cam-block, the bearings can be spaced apart so as to space the cylinders according to the requirements as to the particular fabric to be treated. One of the cylinders is driven from a motor 23 through a belt-and-pulley transmission 24.

Upon the fabric under draft leaving the dome and preparatory to its entering between the cylinders it should undergo change from open-tubular to flat-tubular form. This I have heretofore accomplished by what I have termed a stretcher or herein a spreader, to wit, a flat frame upstanding above the dome and. of such width as at least to distend the fabric, which encloses it, to the flat-tubular form. But due to certain conditions it is found that longitudinal zonal portions ofthe fabric do not travel at the same rate; for instance, on account of the frictional resistance offered by the spreader, particularly in the side folds, the sides of the flattened fabric tend to lag behind its intermediate longitudinal portion, so that the wales of the fabric become curved or bent or not straightv across as they should be (such curve being in this instance convex toward the direction, as upward, in which the fabric is moving) and the fabric leaves the cylinders undesirably distorted in this respect and in fact set more or less in that condition. I therefore provide controlling means which will oiset the resistance responsible for this condition and, where the distortion is incident to the spreader, devise the spreader so as to coact with such means, as follows: Y

The spreader here comprises a horizontal tube 25 forming the base member thereof and these parts forming the spreader proper: stiff wire portions 26 upstanding from the ends of the tube, a stiff Wire bent to form a horizontal mid-portion 2T and depending end portions 28 joined to midportion Z'l by loops 29, couplings 30 receiving the free ends of the portions 26 and 28 and forming therewith telescopic side members of the frame and equipped with screws 39a for clamping them and so that the frame formed by parts 25 to 3B may lbe adjusted' vertically or lengthwise of itself, and blade members 3| projecting downwardly from the loops and outwardly flanking said frame. Members 3| may be adjusted rectilineally toward or from each other, to vary the Width of the spreader, and for this purpose have channeled heads Sla (Fig. 2c) receiving the loops 29 and adapted to be clamped thereto by screws 3 lb. The portions 25 are preferably connected to the tube so as not only to swing down out be detachable therefrom, as shown by Figs. 2a and 2b where the inturned end or trunnion of each has a notch 26a to receive the end of a screw 2527 in the tube, said trunnion being flattened at 25o.

To assemble the trunnions with the tube, said portions are forced apart and the spreader proper brought to approximately horizontal position so that the flats 26e will permit said trunnions to enter the tube Without interference by the screws, whereupon said spreader proper is raised to elevated or normal position thereby bringing the notches into position to receive the screws and thus retain the trunnions in the ends of the tube. In other words, the described (bayonetjoint) connections are such that whereas the structure comprising the mentioned frame and members 3| may, when depressed far enough, be detached from the tube 25, it is adapted to be swung down somewhat for a purpose to appear without the trunnions being detached from the tube.

The tube 25 is penetrated by a bolt 3s upstanding from the top of the dome. When the spreader is in operative position it stands with its upper end reaching into the crotch between the cylinders (Fig. 3) supported by the devices` shown in Fig. '7 which form folding props resting on the top of the dome and holding the tube 25 against the head of the bolt; each of these devices coinprlses a loop 35 clamped to the tube by a setscrew 35 and a leg formed in two sections, the upper section 3l being pivoted to the loop and having a threaded stem onto which the lower section or foot 38 is screwed. Springs 3Q and alternating disks le are interposed between the spreader and dome which tend to support the former yieldingly; in other words, the tube and springs form spring-including means, between the spreader and the dome as a fixed support, normally holding the spreader projecting into the crotch between the cylinders.

The construction with reference to the spreader is such that when the tubular fabric is to be entered between the cylinders, having rst shifted the props tc inactive position and then depressed the spreader against the tension of springs 35 so that the spreader proper will clear the rear cylinder and drawn the upper end of the fabric up so as to: enclose the spreader, said upper end' of the fabric is smoothed above the spreader and the latter returned to its vertical position and then allowed to rise so as to place said upper end of the fabric in the nip of the cylinders.

So far as I am aware the construction of the spreader is novel, especially in these respects, to wit: That it is normally held spring-pressed upwardly and so as to project between the cylinders i8 but comprises a base member 25 and a spreader proper pivoted to the base member to swing downwardly upon depressing the spreader against the tension of the spring sufliciently for the spreader proper to clear one cylinder; andthat the spreader proper is generally inverted U- shaped in form and has, as in Figs. 2a, and 2b, oppositely projecting trunnions at its extremities pivoted in and forming bayonet-joint connections with the supporting structure of the machine.

Each member 3| extends between two rolls lll carried by horizontal shafts 42 having intermeshing gears 43 and connected by a spring 44 so that the rolls will act as presser members or press against the portion of the fabric containing said member 3|, the rolls having rubber or equivalent peripheries lila which will Vobtain a certain degree of grip on the fabric. For the support of each shaft 42 there is a bracket 45 carried by a cross-bar 46 connecting the two standards I5, each bracket being secured to the cross-bar, so as to permit adjustment of the rolls toward or from each other according to the Width of the spreader, by av set-screw lll. The crossbar or shaft 4 6 ls square in cross-section and the bracket has a square socket receiving and fairly closely fitting the same so that, in effect, even though the screw 41 be fully retracted, the bracket is splined to the shaft. One shaft is journaled directly in the bracket, but the other is journaled in a bearing 48 (Fig. 3) pivoted in a fork 49 of the bracket. On the shaft of that gear in each presser member comprising parts Lil) tI-llZ--GS which is the nearer to the cross bar 45 is another gear 5G, these gears being spaced by a portion of the bracket and meshing with the later gear is a gear M which is received in an upstanding fork 35a of the bracket and is splined to a horizontal shaft 5l, there being one such shaft for the system comprising each pair of rolls. This shaft is journaled in a bracket 52 secured to the cross bar 4E by a set screw 53 and having affixed thereto, in the fork of such bracket, a gear 5@ which meshes with the gear Ilia on one of the cylinders I8.

The controlling means thus described acts in the example to advance the attened fabric at its side folds at a faster rate than at such portions it would otherwise travel subject to the frictional resistance of the members 3l; in other Words, so that the drag of the fabric due to such members is compensated for and in the path of the rolls the fabric travels at the same rate as at its longitudinal mid-portion, so that the wales of the fabric are not distorted in the way stated. Given means, as the cylinders I8, for exerting draft on the fabric and assuming that from any cause a portion of the fabric in any limited longitudinal zone tends to lag behind, or otherwise not move at the desired rate, my invention contemplates, broadly, the employment of means, arranged to engage the fabric in only a limited longitudinal Zone thereof and at a point in advance or anterior of the cylinder for controlling the rate of advance of the portion of the fabric in said zone. In the present example, the mem-- bers 3l (which are present to distend or spread the fabric to flat formif not actually to stretch it-and form distinct side folds preventing the fabric passing between the rollers I8 with vagrant creases) actually intervene between and coact with the rolls in each pair as presser mem-- bers, but such is not indispensable, for the driven rolls would obviously serve as controlling means without said members present between them.

Instead of the members 3l being flat and the rolls cylindrical said members may be round in cross section and the rolls have curved periph-- eries as shown in Fig. 9.

It may be desirable in some instances to render variable the controlling action, for instance, if one ply of the fabric tends to move faster than the other. Hence the modification shown in Figs. 8 and 8a which show how the diameter of each roll can be altered. The body of the roll is formed in segments 55 encompassed by an elastic rubber tread portion or band 5S. On the shaft 5l (corresponding to shaft ft2) is fixed a collar 58 having lugs 59 to engage in the notches 55a between portions of the hub of the collar. The shaft is threaded and on it is screwed a conical nut @ii which extends into the roll-hub. By turning the nut on the shaft one way or the other the diameter of the roll may be changed, for instance, so that if either controlling means in the example would not otherwise act at proper speed it may be made to do Having thus fully described my invention what I claim is:
