FILE-FABRIC LOOM.
Specification of Letters Patent.
Patented Apr. 1, 1919.
Application filed August 31, 1917, Serial No. 189,055. Renewed February 3, 1919. Serial No. 274,801.
To all whom it may concern:
Be it known that I, HERBERT J. Horn, a citizen of the United States, residing at Sanford, county of York, State of Maine, have invented an Improvement in Pile-Fabric Looms, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This invention relates to pile fabric looms pile, and by arranging a mechanism whereby the wire motion will operate to skip at intervals forone or a plurality of successive picks, a fabric will be woven in which the surface is partly a pile surface and partly a plain woven surface. If in addition the harness frames controlling the pile warps are actuated by a suitable pattern mechanism a highly-figured fabric may be produced.
My present invention provides means for automatically controlling the wire motion so as to cause it to skip or fail to insert and withdraw a wire at predetermined intervals, thus permitting the production ofthe fancy or figured fabric, as above described.
In order to give an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims.
Figure 1 is a plan view of a portion of a pile fabric loom embodying my invention;
Fig. 2 is a side view of one of the pile wires showing its head;
Fig. 3 is a section on the line 33, Fig. 1.
I have shown herein a portion only'of a pile fabric loom as'it is not necessary to illustrate the complete loom in order to gain an understanding of the invention.
1 indicates a portion of the frame or stand of the loom which supports or contains the magazine 2 for the pile wires, and each pile wire 3 is formed with the head 4 having a slot '5 formed therein for the reception of the withdrawing hook, all as usual.
6 indicates the wire guide which receives and guides the wires as they are being inserted into the shed. 7 is the usual carriage which is mounted for reciprocation upon guides or ways 8 and which is constructed to introduce the wires successively into the shed and is provided with the usual withdrawing hook 9 that is adapted to engage in the slot 5 of the head of each wire and withdraw the wire. The slide 7 is connected by a link 10 to a reciprocating arm or actuator 11, all as usual in pile wire motions.
The magazine 2 is provided with a follower 12 which is pivoted at 13 and is acted upon by a suitable spring 14, said spring having the function of holding the follower 1-2 yieldingly against the head of the wire which has'been last inserted.
The parts which have thus far been described are or may be all as usual in pile wire motions of pile fabric looms, and in the operation of the loom a wire is inserted into the shed by the carriage 7 when the latter moves toward the left, Fig. 1, said wire being guided into position by the wire guide 6, and when in proper position having its head engaged by the yielding follower 12. In Fig. 1 I have shown the carriage nearly at the end of its wire-inserting movement. As the carriage completes such movement, the withdrawing hook 9 wipes over the side of the pile wire head 4 which rests against the wall 15 of the magazine and drops into the slot 5 thereof so that upon the backward movement of the carriage 7, the foremost wire is withdrawn from the fabric. At the next movement of the carriage 7, this wire will be introduced into the shed through the guide 6.
I have provided herein means which operate automatically at predetermined times to prevent the withdrawing hook 9 from ongaging a pile wire head when the carriage completes its wire-inserting movement with the result that at such times the carriage will make its wire-withdrawing movement without withdrawing a wire from the fabric, and hence will make its next wire-inserting movement without inserting a wire in the shed. The automatic means which I haveherein illustrated for thus causing the withdrawing hook to skip is in the nature of pattern mechanism so that the skipping operation of the withdrawing hook will be produced at such times as is called for by the pattern which, .of course, will depend upon the figure that it isdesiredcto pmduce in the fabric. While any suitable pattern mechanism for thus controlling the operation of the withdrawing hook may be employed without departing from my invention, .as I believe I am the first to provide automatic or pattern-controlled means for this purpose, I have illustrated herein a simple and efficient device.
Pivotally mounted at 17 on thecarriage '7 is a two-armed'lever 16, one arm 18 of which is offset to enter an aperture 19in the carriage. and engage the withdrawing hook. The other arm 20 of the lever 16 is provided witha' beveled or cam surface 21 which is adapted to engage a pattern-controlled element 22 as the carriage completes its forward movement. This element 22is herein shown as a pin slidable vertically in the frame 1 and acted upon by. a spring 23 which tends to hold the pin inits lowered position. The lower end of the pin isacted on by a pattern chain 24 which operates over an actuating sprocket 25 that may be driven from any eonvenientmoving part of the loom so that it will rotate in timed relation with the operations of the loom. The pattern chain 24 is shown ,as having appropriately-situated risers 26 thereon. As the pattern chain is actuated,-the risers 26 will engagethe lower end of the pin. 22 and raise the same against the action ofthe spring 23, and as soon as any riser has passed Out from beneath the pin, then the spring 23 will lower the pin into its full line position. The pin is so constructed that when it is in its'lowered or full line position, itis withdrawn from the path of movement of the finger 20, and as a result, whenthis condition exists, the'withdrawing hook 9 will operateto withdraw a pile wire from the fabric upon its backward movement and to insert said pile wire into the shed again upon its next forward movement. When, however, a riser 26 has'been brought into position to elevate the pin 22, then when the carriage completes its wireinserting movement, the cam end 21 of the arm '20 will engage the elevated pin 22, thus swinging the lever about its pivot'17 and causing the offset portion 19 of the arm 18 to move the withdrawing hook 9 into the dotted line position, Fig. 1, in which position it does not engage the head of any of the pile wires in the magazine. As a result, the with drawing hook will fail towithdraw a pile wire from the fabric upon its return movement, and as no wire has been withdrawn', there will be no wire to insert on the next forward movement of the carriage 7. If at toinsert a pile wire. On the other hand, if the pin 22 is not elevated by a riser, then the withdrawing hook will be operative to with draw a pile wire, as usual. The fabric which is thus woven will have a surface which is partly a pile surface and partly a plain sur face, the proportions depending upon the characterof the pattern mechanism.
I claim:
1. In ,apile fabric loom of the type having means for withdrawingfrom the fabric being woven a pile wirethat has been woven therein and then inserting said pile wire in an open shed, pattern mechanism to render inoperative at predetermined times. the said means for withdrawing apilewirewhereby at such times no pile wire will be inserted into the shed and a pattern will thereby be produced in the fabric.
2. In,a pile wire loom of the type having a reciprocating carriage adapted during its movement in one direction to withdraw from the fabric a pile wire that has been woven therein and upon itsnext succeeding movementin. the other direction to insert said pile wire into an open shed, pattern mechanism operative at predetermined times to cause said carriage to, fail to withdraw apile wire during 1ts wire -withdrawing movement whereby a pile wire will not be inserted at its next wire-inserting movement and a pattern will. thereby beproduced in the fabric.
3. In a pile fabric'loom of the type having a reciprocating member adaptedduring its movement in one direction to withdraw from a the fabric apile wirethat has been woven therein and during itsjnext movement in the opposite direction to' insert said pile wire in an open shed, pattern mechanism for controlling the operation of said member at each wire-withdrawing movement to determine whether said member will be operative or inoperative to withdraw a pile wire whereby a pile wire will be inserted in or omitted 'from each shed and a corresponding pattern produced in the cloth depending on the operation of the pattern mechanism.
4. In a pile fabric loom, thecombination with meansfor withdrawing and inserting a pile wire, of pattern mechanism forcontrolling the operation of said means to render the said means inoperative to insert a wire at predetermined times wherebya pattern will be produced in the'fabric. I
In testimony whereof, I have signed my name tothis specificatio HERBERT J HOPE.
