TAKE-UP MECHANISM FOR CIRCULAR LOOMS.

SPECIFICATION forming part of Letters Patent No. 503,863, dated August 22, 1893. Application tiled April 10l 1891. Serial No. 388,419. (No model.) Patented in England March 1l, 1892No. 4,7817.

To all whom it may concern:

Be it known that I, ALBERT DE LAsKI, o Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Take-Up Mechanism for Circular Looms, (for which I have obtained a patent in Great Britain, No. 4,817, dated March ll, 1892;) and II do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that part of circular looms which involves the means, or mechanism, employed for drawing oft', or taking away,from the weavingpin,the tubular woven fabric (whether taken 0E by itself, or in connection with some sort of tubular lining, or solid core),and usually designated the takeoif mechanism.

Previous to my invention, mechanisms for this purpose have been devised and used, an instance of one of which is to be seen in Letters Patent granted to me December 20,1887, No. 375,135, and the take-off mechanism which constitutes the subject of this application might be used in connection with a loom, such, for instance, as shown in my said patent; although I have practically employed it in connection with an improved circular loom, novel features of which I have made the subjects matter of two other applications for Letters Patent, filed simultaneously with this one, and serially numbered, respectively, No. 388,417 and No. 388,418.

My present invention has for its main objects, to provide for use, in connection with an improved circular loom, of that type, which permits the presence of the operative within the frame-work of the loom and beneath the weaving mechanism, (in order to conveniently run, or manage, the machine) a take-off mechanism that will not interfere materially with the movements of the operative, and one over which he can have convenient and perfect control, so as to stop its automatic action at pleasure and manipulate it by hand, and also one which can be adjusted, by the shifting and addition of certain parts, so as to operate perfectly to take olf either a woven tube in a practically iattened condition, or to take off a woven tubular jacket which surrounds, either a solid cylindrical article, or a rubber tube; in which latter case it is necessary, of course, to take off the jacketed and finished article without mashing it.

To enable those skilled in the art to which my invention relates to make and useatakeoff mechanism, containing, either wholly, or

partially, the novel structural features made the subject of this application, I will now proceed to more fully describe my invention, re-

ferring by letters to the accompanying drawor side view partially in section, of my improved take-off mechanism, and showing only so much of the lower portion of a circular loom as is necessary, in order to properly explain the character of my present invention. Fig. la, is a detail skeleton view, on an enlarged scale, of some of the parts seen at Fig. 1, and illustrates, more particularly, the shifting of one of the gears, on a splined shaft. Fig. 2, is a similar elevation, or side view, of the take-0E mechanism, viewed in a direction at right angles to that in which it is seen at Fig. 1, and from the left hand side. Fig. 3, is a side View, or elevation, of the contrivance, showing the side opposite to that seen in Fig.v 2, and also showing the shifting, of certain parts, and the elimination and addition of certain parts made in changing the take-off mechanism, to adapt it to the removal, from the weaving pin of the loom, ofr

a jacketed hose, or other article, which has to be drawn away from the loom in a tubular, or unfiattened condition. Fig. 4, is a partial top-view, of the mechanism shown, in elevation, at Fig. 3. Fig. 5, is a perspective view of one of the devices, detached.

In the several views the same part will be found always designated by the same letters and numerals of reference.

Suitably secured, to a separate foundation support, or to, the central portion of the metallic base-plate, of the loom-frame, is a hollow metallic post, or column-like stand W, within, and on, which are arranged all the working-or operative, parts `of the take-off mechanism. Within this standis arranged, in suitable bearings, as shown, the central vertical shaft which has mounted on i`t,tov

turn loosely, vnear its lower end, a beveled pinion 102, that is in" constant engagementg..

that runs close' to -thel base-plate o'fthe ina-f chine, and to the door on which the machine rests, and which is provided, at its outer end, with a worrnlgear (not` shoWnlthat'engage's with .the'wo'rmlon the -loWer,end-'ot a ver-f tical shaft y. Said shaft, through the me-'l` dium of 'al-pair ot beveled pinions (not shown),2 receives the necessary power and motion, (atj itsuppe'rend) from the main drive-shaftof the loom.

In the operation of thus taking off the iiattened woven fabric, the rotatory shaft x3, of course, imparts the necessary continuous movements, through the medium of the pinions 104, and w3, and the system of spurvgearing shown, to the three take-off rolls; and,

to vary the speed of these take-off rolls (to adapt the machine to the taking-off of different sized fabrics, woven at different speeds) the removable, or changeable, pinion e7, is removed and apinion of another size substituted therefor; the spindle of the adjustable pinion z being, of course, shifted in the slot of stand 0c y to properly engage with the new pinion substituted for e7; all in a manner familiar to the ordinarily skilled mechanic.

As it is sometimes necessary, or expedient, to run the circular loom in different directions, provision is made for reversing the action of the driving pinion 104, on the take-off rolls, (which latter must, of course, always revolve in the same direction, to pull the woven fabric away from the weaving-pin of the loom, and properly discharge it.) This provision consists in having the beveled pinion w3, removable, as before remarked, from the spindle z', and the latter easily detachable from the metallic stand of the take-pif mechanism, so that, in the event of changing the direction of motion of the entire loom mechanism, the operator has simply, while removing the pinion e, to pull, or draw out, the spindle z', and by putting his hand through,the.

aperture a ,shift the position of the beveled pinion w3, so-that it will engage with the-pinion fw, on the opposite side of the latter, and then replace the spindle e', and reapply its pinion e7, when, although the pinion w4, may then be rotated in the opposite direction to that in which it previously turned, the spindle e', and all the gears and rolls of the takeoff mechanism will rotate in the same direction in which they formerly turned. This shifting of the bevel pinion w3, on the splined shaft, or spindle a', is fully illustrated at Fig. 1', where I have shown the parts ou an enlarged scale, and in which 20 represents the spline, or groove, in the shaft z', and where I have shown the bevel pinion w3, shifted to engage with the driving bevel pinion m4, at a point diametrically opposite to that at which said pinion w3, engages with said gear m4, when in the position shown at Fig. 1. The said pinion w3, being shown merely in dotted lines, in Fig. 1, to better show the shifting manipulation.

When it is desired to shift, or adjust, the parts of the take-off mechanism, to adapt it to the removal from the weaving-pin, of a finished fabric, or jacketed article, in a cylindrical, or unflattened, condition, all of the rolls, 0o, are removed from the machine. The lower one of the three spindles, in the headframe, is then removed and replaced in suitable journal boxes in the slotted,bracketlike, projections, or lateral ear-pieces Q7, of the head-frame, in such manner that the spurgear Q3 will engage with the pinion Q of the upper spindle 1; and the said upper spindle 1 and the said shifted spindle 3 are then provided with the set of circumferentiallygrooved take-off rolls E; all as clearly shown at Figs. 3 and 4- of the drawings. Then by a proper adjustment and securement in place, of the detachable cross-bar, as shown, with its ovalshaped, warped, guide-ring, or eye d8, as shown, and a proper adjustment of the hinged head-frame, by means of its adjusting screwbolt a, and nut @10, see Fig. 3 (so as to bring the space between the two grooved rollers vertically in line beneath the axis of the weaving-pin of the loom) the tubular fabric will be held and guided, as it passes through the eye d8; beneath which it will pass into the bite of the grooved rollers, E, and will be led by them, and drawn away, or pulled down, with a uniform speed, and discharged from the loom in a perfect condition.

The object aud eect of the oval-shaped eye d8, are to avoid the partial flattening of the cylindrical article (if tubular and compressible), in an opposite direction,whieh practice and experience have demonstrated it is the tendency of the grooved rollers to effect; and to prevent the injurious effects, on some kinds of finished articles, resulting from any such partial `fiatteuing of the finished fabric, or from any pinching of the fabric, at opposite points, between the peripheral surfaces of the take-0E rolls, and at the vicinity of the circumferential lines where the grooves run into the plain surfaces of the peripheries.

I have found, 'by practice and experience, that not only is it necessary to employ some guiding device, such as the eye d8,which will distort the cylindrical fabric, if hollow, in the direction indicated, but also that it is very important to have this guiding eye shaped so, as to lie as closely as possible to the peripheral surfaces of the take-off rolls, where the nished article enters the bite of the rolls, and, for this reason, I make the ellipticallyshaped guide-eye, curved, or warped, as indi` cated (see Figs. 3 and 5), in order that it may guide and hold the finished fabric, or article, in the best possible shape to permitthe takeoff rolls to draw away the article, without any injurious effect on the latter; and I consider this structural feature of the take-off mechanism an important one, where the said mechanism has to be used under the conditions and for the purposes illustrated at Figs. 3 and 4.

It will be observed that, when adjustable in either of its two positions, or when doing either of the two species of work for which it is de- YSo roo
