ATTACHMENT FOR LOOMS.
A pplieation filed April 17, 1923. Serial No. 632,643.
To all 10 lap m, it mag concern Be it known that LARrrron J. Amer, a citizen of the United States, and a. resident of Middletown, in the county of Middlesex and the State of Connecticut, have invented a certain new and useful Improvement in Attachments for Looms, of which. the. following is a specification.
My invention relates more especially to a device for enabling the fabric being produced in a loom to be accurately positioned, after it has been moved for any purpose, so that the weaving will be resumed at the proper point and without leaving any im: perfection in the cloth.
ne form of device embodying my ipyention and in the construction use of which the objects herein set out, aswell as others, may be attained, is illustrated in; the accompanying drawings, in which-.-
Fig. 1 is a view of a portion of, a loom showing my improved device applied to the breast-beam thereof, the dotted lines show ing the position of the adjusting device as overlying. the fabric when not in use.
Fig. 2 is a view in section through a reed and breast-beam of a loom on a plane denoted by the dotted line 2-2 of Fig. 1, and showing my improved device in place thereon.
In the operation of weaving, when a dc fective place appears in the fabric and as soon as it has been detected, the loom is stopped, and is turned forward by hand so that the fabric is moved to an accessible position and the imperfection is removed by picking out the weft threads, and the loom is then turned back to locate the fabric, as nearly as possible, in the position it occupied before it was moved forward, and the weaving is then resumed. In thus returning the fabric to its former and weaving position,
it is a very difiicult matter, and requires much time, care and skill, to locate the fabrio in such position that the Weaving will again be taken up in the proper place and without leaving an imperfection in the fabric. It is to obviate this difficulty that I have produced my improved device, and by its use the fabric in the loom, after having been moved for any reason, may be quickly returned to its correct weaving position and may be so accurately placed that the weaving will again take place at the point where it terminated, and therefore no imperfection will occur in the fabric by reason of the interruption in the weaving process.
Such device is shown in the accompanying drawings in which there. is illustrated one end of the breast beam 4 of a Loom secured to one of its supports 5 said; beam having guide rolls. 6-7mounted therein to receive the woven fabric 8. This fabricterminatesin theusu'al manner: at point ef weaving, this-being the point where the woven fabric joins the shed 1 0, shed extending. in the usual manner through the reed 11. All of the parts thus far described are of old and well known construction and will be readily understood by those. skilled in the art without further referenceherein.

P q l y ma te 0. t ase 1 and s. fam d t ne dir st joa a by means of a spring 15 An indicating fina 16 adiu blr secur d. to. he Peter in any suitable manner, in the construction shown the end of the finger passing through a pivot stud 17 mounted in the pointer, which pointer is adjustably held in said stud as by means of adjusting nuts 18 engaging the thr-eaded end of the finger. The opposite end of the finger is bent as at 19 so that it may be engaged within the cross of the shed 10, and is shown in Figs. 1 and 2 of the drawings. 7
This device, in aflixing it to the breastbeam, is sopositioned that the bent end 19 of the finger will engage within the crotch of the shed 10 and approximately in a line that will be traversed by the weft thread as it is carried through the shed by the bobbin, and the pointer, in this position of the finger, will be registered with the zero point, or such other point as may be desired. Having thus been properly adjusted the 'finger may be located in its inoperative position overlying the fabric and as shown in dotted lines in Fig. 1 of the drawing. When the fabric being woven is moved from its weaving position for any reason, and as hereinbefo-re referred to, and it is desired to again place it in its weaving position, the following operation takes place. Supposing the fabric to have been moved forward for the purpose of picking out threads, which is a common operation, the bent end 19 of the finger is placed between the warp threads comprising the shed and the machine is now turned backwardly until the fabric is at a point where the engaging finger moves the hand so that it registers with the zero mark. hen the engaging finger is placed within the shed and between the warp threads as above described, the spring 15 will move the finger 16 forwardly so that the finger 19. will engage the crotch, and in the backward movement of the fabric as above described the finger 16 will be swung on its pivot in opposition to the force of the spring 15. When the parts are thus positioned the finger may be removed from the shed, as by swinging it on its pivot against the tension of the spring 15 until the bent end 19 is re moved from the shed and the spring 15 will then swing the finger to an inoperative position, as shown in dotted lines in Figure 1 and the machine being started the weaving will again take place at the exact point where it was discontinued, and there will, therefore, be no imperfection in the fabric by reason of the weaving taking place at the wrong point.
In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.
I claim:
1. A loom including mechanism for weaving a fabric therein, said mechanism including means for forming a shed, a tensioned horizontally swinging element normally displaced from the shed and adapted to engage within said shed, and an indicating member operatively connected with said element to denote its position.
2. A loom including mechanism for weaving a fabric therein, said mechanism including means for forming a shed, a tensioned engaging member normally disengaged from the shed and swingingly movable to its operative position in a horizontal plane to be engaged within the crotch of said shed, and a means carrying the indicating member for denoting the position thereof. 3. A loom including mechanism for weaving a fabric therein, said mechanism including means for forming a shed, an indicating finger to engage within thercrotch of said shed, and an'indicating pointer supporting said finger, said finger having an angle end adapted to be engaged within the crotch of the shed, said pointer being pivotally mounted to denote the position of said finger and spring pressed for normally holding the end of the finger engaged within said crotch with the finger swingingly movable in a horizontal plane and in operative position when not in use.
