UNITED STATEE ARTHUR J. HARRIS, OF PATERSON, NEW JERSEY.
LOOM.
Application filed. July 1,
This invention relates to looms of the type set forth in the Harris Patent No. 950,021, for example, in which a device for receiving the finished goods is driven rotatively from a rotary warp-supply device, whereby to wind up the goods on the receiving device as the warp is unwound from the warpsupply device. In the winding on the re ceiving device the practice has been to shift a guide for the goods lengthwise of the axis of the receiving device from time to time so as to form a package consisting of a succession of piles in the form of flat coils arranged side by side. When the goods are very narrow ribbons, and especially if when narrow they also have relatively thick cord-like edge portions, such coil-piles frequently have their outer convolutions slip off laterally, and sometimes an entire coil-pile will collapse completely, so that in the finished package the windings are disarranged and occasionally badly snarled. The object of the present invention is to avoid this difliculty. Instead of forming the package in distinct coil-piles in which each pile is a coil of the flat type the windings proceed spirally first in one direction and then in the other around the axis of the receiving device and this is advantageously accomplished as follows: Given a revolved receiving device on which to wind the goods and a guide offset from the axis of winding and around. which the goods extends to said device, if the winding is effected on said device at a point remote from a plane perpendicular to the axis and which is coincident with said guide the winding will tend to progress or traverse toward said plane. In the present invention I utilize this phenomenon to obtain traverse in one direction and to obtain the traverse inthe other direction I utilize another guide which at intervals imparts shifting impulses in the latter direction.
In the actual construction herein set forth, where the axis of the receiving device projects rearwardly from the loom, the first guide is arranged in a vertical plane at least as far rearward as the vertical plane of the relatively forward end of the package to be formed and the means to impart the impulses operates from the latter plane rearwardly.
The invention broadly consists in the combination, with a support and a receiving device iournaled therein and on which to wind the goods, of a guide arranged offset from of said device whisk the supply 1925. Serial No. 49,799.
goods extends to said device, and means between said guide and device, to impart shifting impulses to the part of the goods between said guide and device substantially lengthwise of said XlS, always in the same direction and only at one side of a plane perpendicular to said axis and occupied by the said guide and (in order that the resulting layers of windings shall be superimposed on each other) all within the same zone.
In the accompanying drawing, Fig. 1 is a side elevation of a loom, partly 1n section, embodying the invent-ion; and
Fig. 2 is a rear elevation of so much of the loom as includes the invention, the warpsupply devices being removed.
As in the said Harris patent, 1 is the loom frame, 2 the breast-beam-carrying glass-bars '3, and 4 the usual beam for supporting glass bars 6. As in said patent each warpdevice 7 and goods-receiving device 8 is journaled on a spindle 9 in alinement with the other and they may be pinned or otherwise interlocked together so as to rotate as a unit. The warp wound on each device 7 is marked 10 and indicated by a light broken line and the woven goods wound on each device 8 is marked 11 and indicated by a heavier broken line excepting adjacent said device 8 where it is shown-by solid lines. As the weaving proceeds and in consequence each device 7 rotates under the pull of the warp to deliver the same it rotates the corresponding device 8 so as to wind up the goods thereon as set forth in said patent.
W hat I have hereinbefore termed the first guide is afforded in the present instance by a transverse beam 12 at theback lower part of the loom; it may be shed with. a metal angle iron 12 to receive the actual contact of the goods 11. In the present case this guide is arranged somewhat forward of the vertical plane with which the forward end of each goods package to be formed is coincident so that the tendency of the goods is to traverse forwardly in the winding (or in other words to assume the line representing the shortest distance between the guiding point 12 and the package) whenever the winding is actually occurring rearward of such forward end.
The mentioned movable guide is afforded by a bar 13 in the present case forming the top bar of a frame 13 hinged on a horizontal transverse axis tothe 12. This frame intervals and then permitted to swing forward again by the following means. On a transverse shaft 1% journaled 011 the frame 1 is fixed a cam against which bears frame 13 which may have a roller 16 to afford the actual contact; there may be any number of these cams and rollers as the length of the frame 13 transversely of the loom may require. A sprocket and chain system 17 is shown to afford means for rotating the shaft lat from any suitable going means in the loom, as the rotating take-up shaft 18.
lVhen the loom is operating the cams 15 are constantly rotating. The sheet of warp and woven goods being held under tension by the weights 19 slung in loops formed therein and depending from rollers 20 on the top of the loom frame, the goods maintains the frame 13 against the cams. Consequently, while the winding is proceeding, at spaced intervals the cams act to force the goods rearwardly, thus producing the rearward traverse, and in the remaining or alternate intervals they allow the goods to respond to the tendency to traverse forwardly, the frame being incidentally held in contact with the cams by the goods during these intervals.
In this way the wound packages are formed in successive spirals alternately coiled first from one endL and then from the other end of the package, so that the component parts of the package are integrated with each other and a compact and stable package is produced.
It will be noted that while the shifter 13 yields (when free to do so) to the part of the goods between the guide 12 and the receiving device in its tendency to assume a plane perpendicular to the axis of said device, it nevertheless is normally urged against said part of the goods, thereby al ways preserving it in a state of tension and reducing the force and therefore simplifying the means necessary to impart the work ing impulses thereto, which is a matter of some consequence where there are a large number of goods receiving devices in the loom.
Having thus fully described my invention what I claim and Patent is:
1. In combination, with a support and a receiving device journaled therein and on which to wind the goods, a guide arranged offset from the axis of said device and around which the goods extends to said device, a goods shifter normally urged against the part of the goods between said device and guide in a direction generally lengthwise of said axis, said part normally acting to over come the pressure of said shifter and assume a plane perpendicular to said axis, and means to impart goods-shifting impulses to said shifter always in the same direction and generally lengthwise of said axis, only at one side of said plane and all within the same Zone.
2. In combination, with a support and a receiving device ournaled on a substantially horizontal axis and on which to wind the goods, a guide below said device around which the goods extends to said device, a goods shifter pivoted on a horizontal axis crossing the first axis and arranged to bear against the part of the goods between said guide and device, and means to impart goods-shifting impulses to said shifter always in the same direction and generally lengthwise of the first axis, only at one side of said plane and all within the same zone.
3. In combination, with a support, and a receiving device journaled so as to project laterally therefrom and on which to wind the goods, a guide below said device around which the goods extends to said device, a goods shifting structure pivoted on a horizontal axis and bearing against the part of the 'oods between said device and guide at the relatively inner side thereof, and means to impart shifting impulses to said structure always in the same direction as said device projects and only at the relatirel outer side of a plane perpendicular to said axis and occupied by the guide and all within the same zone.
In testimony whereof I my signature.
ARTHUR J. HARRIS.
