ToaZZ'wwm t may concern.-
Be it known that I, IRVINE C. BEATTY, of Merchantville, Camden county, New Jersey, have invented an Improvement in Looms, of
which the following is a specification.
Myinvention has reference to looms; and it consists of certain improvements, all of which are fully set forth in the following specificathe warps.
The particular construction of my lettingo or tension device for these various warpthreads is fully described hereinafter when referring to the drawings.
A second part of my invention consists in devices for bringing the various wai-ps from the heddles in separate layers over the top of the loom and by suitable guide-rods or rollers to the tension or letting-oft devices and locating such tension or letting-oft devices in the front or back ot the loom, but separated from it sutciently to enable the operator to pass between the loom proper and the up- `wardly-ertendin g warp-threads and their tension or letting-oft devices. This enables the operator to watch the weaving of the various webs and at the same time by simply turning his head to have in full view every warpthread which is-being fed to the loom, thereby being enabled to observe and in position to overcome any defect which might exist by the breaking of a warp-thread long before the end of said broken warp-thread passes through the heddle.
lVhile my invention is particularly adapted tolooms forweavinga series of separate webs when all are controlled from the same power mechanism, it is also applicable to any type of loom in which two or more sets of heddles are employed.
In the drawings, Figure l is a sectional elevation of aloom and the tension or letting-off devices embodying my invention. Fig. 2 is a perspective view of one of the letting-ott or 'of the tension or letting-off devices.
tension devices. Fig. 3 is a front view showing two of the guide-rollers of a pairof tension devices, illustrating how the weights of the upper roller may pass below the level of the lower tension-roller; and Fig. 4 is a perspective view of one of the brake-frames for carrying the tension-roller and guide-roller, showing the use of vertical guides for the tension-roller.
A represents the loom proper, which is provided with the usual reed and lathe and the heddles B,`of which there may be any desired number. To the rear of the heddles are Aarranged a series of bars, guides, or rods C, preferably o ne for each series of warps. Ar-
ranged to the upper part of the loom over the rods C are a similar series ot rods or lguides D, and again in front of the` machineand above where the operator would pass in attending theloom is a third series of' such bars or guides E. The bars or guidesD andEare arranged obliquely, so as to keep the various layers of warp-threads separated as far as practicable.
In the front of the machine is arranged the tension or letting-oft devices F, which are located one above the other and so positioned with respect to the loom proper that a passage-way P is formed for the operator, whereby he may either attend the loom A or examine thevarious warps passing over the spools If the tension devices are located in the front of the loom, .then-the passage-way Pis arranged-beltween the lathe portion of the loom and the sage-way P would be arranged between "thle heddles and the tension devices. In'either case there is a passage-Way upon both's'i'des f a bobbiu or spool G, journaled in an uprightl frame H and carrying the Warps for one of IOO ICI
the heddles, and a frame I, pivoted below said spool at J, in which is journaled or supported aroller or guide-rod L. Tension-cords K pass around the flanges g of the spool G, one end of which cords is fixed to the frame H by being connected to the pivot J, and the other end of which cord is connected to the frame I at a distance from itspivot orfulcrumpoint J. It will be seen that anytendency to press down the freeend of the frame I will cau-se a tension to be exerted by the cords or bands K upon the spool or bobbin G and prevent its unwinding, and vice versa. The warpthreads pass from the spool G over the guide rod or roller L and under a roller or guide M, which is vweighted at each end by weights N. From under said roller or .guide M the said `warps pass upward to the guide-rods E, thence to guide-rods D,thence downward under the guide-rods lC to the lleddles. The axles of the guide-rollers M may be guided invertical guides t' on the frame I, said guides being clearly shown in Fig. 4. Such guides prevent any lateral swaying of the guideroller. However, if desired, these guides may be dispensed with. As the loom .takes up the warp-threadS .the guide rod or roller is lifted until it lifts the frame I, releasing the tension on the spool G, which action allows ,the weighted roller or guide M to pull down gradually, causing the vspool -G to let o fa cert-ain amount of the warp-threads.
As soon as the roller or guide M falls the ,downward pressure of vthe warp-threads on the roller L forces down the `frame I and arrests further movement of the spool `G. During ythe further action of the loom the warp which is taken up in the manufacture of the fabric draws upon that portion of the warp in which the roller or guide M iS suspended and gradually lifts said roller or guide M 'and its weights N until it again lifts the frame I and repeats the operation of letting oit the given amount of warp, as before. There is a series of these tension and let,- `ting-.off devices arranged one above the other in the frame F, as indicated in Fig. l, and thel guide rods or rollers E are arranged slightly at an angle to the loom, so that the various layers of warp-threads rise upwardly and at i fulcrufmrpeint J. A convenient method is to .of the same size, the next two larger, but of the same size, and so on-thus enabling the' rollers L and M to be carried farther out to insure a more ready guidance of the warp to the guide-rods E and a clearance of the tension-weights. This difference in the size of the frames [is clearlyshown in dotted lines in Fig. l. Where the vertical space is limited for any given number of spools G, it is desirable to make the axle of the upper tensionroller M of a pair longer, so that the weights N, suspended therefrom, may descend outside of the weights N of the roller M immediately below, as is shown in Fig. 3. The weight N of the next pair above being located nearer to the spool G, they could descend without coming into contact with the weights below. By this construction a maximum 'vertical movement of the roller M may be had with the limited vertical space in which the spools rG are located.
By my vimprovement l am enabled to Vfeed the various threads in fiat layers, so that there is no tendency whatever for tangling or knotting of the various threads making up the fabric, and yeach :and every thread can be readily observed by the operator at alltimes, .thus overcoming any Vcomplication which Ymight resultfroin defects'in the-threads when fed to the loom in rope-like layers, as has been customary heretofore.
The construction of the loom may be such as is heretofore welll known, and may be varied -to suit the requirements of the manufacture of any special kind of fabric. Gonsequentlyl do not limit myself `to the details thereof. Likewise the details of my improved tension device may be moditied'without departing.
from the spirit of the invention, and I might add that, broadly considered, it is'immaterial where the said tensiondevice is located with respect to the loom; bu-tI prefer to locate it as shown, so as to form the passage-way for the operator between the spools the loom proper.
