PILE-FABRIC LOOM.
Specification of Letters Patent.
\ Patented Feb. 2, 1915.
Application filed December 31, 1913. Serial N 0. 809,676.
'1 '0 all u'lmm it may concern:
Be it known that I, Gnome Cnossnsno, a citizen of the United States, residing at Revnoldsville, in the county of Jefferson and State of Pennsylvania, have invented a new and useful Pile-Fabric Loom, of which the following is a specification.
This invention relates to a pile fabric loom and particularly to that class of looms in which longitudinal pile wires are used upon which the pile loops are formed.
The object of this invention is to provide improved means for guiding the pile wires and the pile warp threads to cause the latter to descend alternately upon opposite sides of the pile wires.
\Vith this object in view my invention comprises certain devices, arrangements and combinations of parts which will be hereinafter described and more particularly pointcd out in the appended claims.
A preferred form of my invention is shown in the drawing in which Figure 1 is a side elevation of my invention together with certain parts of a pile fabric loom; Fig. 2 is a perspective yiew of one of the guiding devices; Fig. 3 IS a top plan view showing the devlces for angular-1y moving the guides; Fig. 4 IS a similar View showin the same parts in a different angular pos1tion; and Figs. 5 and 6 are dlagrams showing the relation of the pile warp thread to the pile wire and guide.
In the drawings the device is shown attached to a loom for weaving Wilton or Brussels carpet or similar pile fabric indicated at A, the lay being shown at 10 and the usual reed at 11. The binder warp threads 12 and 13 and the stuifer warp 14 are controlled by the usual harnesses 15, 16 and 17. Each pile warp thread 18 passes through a harness eye 19 which may be operated in accordance with a pattern by a jacquard mechanism or other suitable device.
The longitudinal pile wires 2 are rigidly supported upon the loom at their front ends while their rear ends are free but extend between the parallel sides of the guides 21. Each guide in the preferred form comprises a U-shaped loop of thin sheet material secured at its lower end to a block 22 but two separate strips may be secured to each block in place of the single U-shaped strip 1f desired. The blocks 22 are each provided with two pair of oppositely disposed lateral pro- ]ections Every other pile wire extends within one of the U-shapcd loops while the alternate pile wires extend between adjacent guides, as shown in Figs. 5 and 6.
The guides are supported at their lower ends between a pair of longitudinallv movable rack bars 24 mounted in guides 2 1.
The lateral projections 23 prevent verticalmovement of the guides relative to the rack bars, the rack teeth engaging the intermediate portions of the blocks 22 between the projections 23. Each rack bar is connected atone end by a link to any suitable operatlng mechanism (not shown) for causing alternate longitudinal movement of the bars. Such alternate movement will cause an angular movement or partial rotation of each guide 21 about a vertical axis, the rear ends of the pile wires 20 terminating at points substantially coincident with these vertical axes. In the preferred form, the pile Wires terminate slightly short of the vertical axes but the terms used in the claims are intended to cover a construction in which the wires terminate either at or slightly before reachlng the vertical axes of the guides. One of the pile wires and one set of the pile threads are guided between each pair of adjacent guiding surfaces.
In the operation of the device the desired pile threads are raised by the harness eyes 19 and the angular position of the guides 21 relative to the pile wires is thereafter changed by the longitudinal movement of the rack bars 24. Reference to Figs. 5 and6 will show that such angular movement guides the pile threads to the opposite side of the plle wires from that which they previously occupied, so that when the pile threads are lowered, they will be carried down upon the opposite side of the pile wires, thereby forming loops of pile warp over the wires. It will thus be seen that I have provided an exceedingly simple arrangement by which to guide the pile threads and that by this arrangement I am able to dispense with the false reed which has been commonly used for crossing warp threads in looms provided with longitudinal pile wires. The omission of this reed adds greatly to the ease of operation of the loom inasmuch as it renders the various harnesses and. warp threads more easily accessible.
Having thus described my invention it will be evident that many changes and modiparting from the fications can be made therein without do; spirit and scope thereofand I do not wish to be limited to the particular details disclosed herein, but
" What I 'docla'im is-:-
1. In a pile fabric loom, longitudinal pile wires, guides for the pile wires and pile threads, and means for chan the angular relationof said guides to sai wires and threads, said guides comprising. arallel flat surfaces extending substantial istances on each side of the axes of rotation of the guides, and the rear ends of said pile wires terminating at substantially themiddle of the width of said flat surfaces.
- 2.. In a pile fabric loom, longitudinal pile wires, guides forthe. rear ends of said wires and for the pile threads, and means to change the angular relation of said guides and wires,
said means comprising oppositely movable members engagin respectively the front and rear lower e ges of said guides, said members constituting the only means for laterally positioning the guides in the loom.
3. In a pile fabric loom, longitudinal pile wires, guides for the pile threads and means to change the-angular relation of said guides and threads, said guides being entirely supported by their lower ends and said" means cooperating with the lower ends of said I guides to move them angularly.
4. In a pile fabric loom, longitudinal pile wired 'des for hel "ar 0f wires and fin iz lie pile th reads aniiiiimilihm e the angular relation or saidguides andwires said guides each consi'sti 1of a U-shaped strip of thin sheet material 'aving its lower ends secured to a sup block having two pair of opposite lateral projections cooperating with the upper and lower edges of opposite y moving rack bars to secure said guiies against longitudinal movement in sax tion of the side edges'of said blocks engag ing the teeth of the oppositely movable rack bars and an ularlymovable thereb 5. In a i e fabric loom, longitu inal pile wires, gui es for the rear ends of said wires and'for the pile threads and means to change the angular relation of said guides and wires, said guides each consisting of a U-shaped strip of thin sheet material having its lower ends secured to a supporting block and bein spaced a art and guiding one pile wire and one set 0 warp threads within each loop and another pile wire and set'of threads between each twoadjacent loops.
In testimon whereof I have hereunto set my hand, in t e presence of two subscribing witnesses.
