DOUBLE-P-ILE-FABRIC LOOI/I.
Application filed January 25, 1923.
To all whom it may concern:
Be it known that I, Josnrn 1*. BENOIT,
- a citizen of the United States, and resident of Sanford, county of York, State ofMarne,
have invented an Improvement in Double- Pile-rabrio 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 a double-pile fabric loom and has particular reference to the knife for cutting the pile threads to divide the double fabric into two separate pile fabrics.
One feature of the invention relates to an oscillatory knife-actuating member and connections between the latter and the knife by which the knife is carried back and forth across the loom in timed relation with the vibrations of the lay thereby to divide the double pile fabric.
Another feature of the invention relates to novel means for actuating said oscillatory member from the cam shaft from which the lay is vibrated.
Other features of the invention will be hereinafter pointed out in the following description and one embodiment thereof.
In the drawings:
Fig. 1 is a side view of a loom embodying my invention;
Fig. 2 is a sectional view illustrating the manner of supporting the knife and the way in which it operates;
Fig. 8 is a plan view of a portion of the knife support with the knife thereon.
1 indicates the loom frame which may have any suitable or usual construction and 2 indicates the lay which is carried by the lay swords 3 that are supported on the rock shaft 4 as usual in looms. The lay 2 is of that type adapted to support two shuttles for weaving a double-pile fabric.
The loom herein shown has the three warp beams 5, 6 and 7. The warp from the warp beam 5 constitutes the body warp of the fabric and the warp from the warp beams 6 and 7 constitutes the pile warp.
Situated in front of the clothmaking point is guide member 8 which extends transversely across the loom and is provided with a slot or opening 9 through which the double-pile fabric is delivered.
The knife for dividing the pile fabric Serial No. 614,908.
is indicated at 10 and it is constructed to be moved back and forth across the loom and operates in the opening- 9 as best seen in Fig. 2. This knife is supported in. a holder 11 which is mounted on a slide or carriage 12 that is adapted to reciprocate back and forth in ways 13 formed in a knife-supporting guide 14: which extends across the lay in front of the guide member 8..
As the double-pile fabric indicated at 1-5 is carried through the opening 9 of the guide 8 the knife 10 acts on the pile threads which pass from one fabric to the other thereby dividing said double-pile fabric into two separate fabrics indicated at 16 and 17 respectively. These separate pile fabrics 16 and 17 are wound on cloth rolls l8 and 19 which are situated one above and the other beneath the knife-supporting. guide 14.
The carriage 12 for the knife 10 is moved back and forth in the ways 13 by means of a flexible cord or connection 20, one end of which is connected to the carriage as shown at 21 and which passes around a direction pulley 22 at one side of the loom and then extends across the loom and over a direction pulley 23 at the other side of the loom, thence downwardly around an actuating pulley 24; journalled on the loom frame at 25 and then over another direction pulley 26 and thence parallel to the supporting guide 14 to the carriage to which it is connected as shown at 27.
With this arrangement it will be seen that the rotation of the pulley 24 will move the knife 10 transversely across the loom and by rotating said pulley first in one direction and then in the other the knife 10 will be given a reciprocating movement back and forth across the loom.
The means I prefer to use for thus operating the pulley 2a is such as to cause the knife to be moved back and forth in timed relation with the vibratory movement of the lay 2. The means herein shown for vibrating the lay are similar to those illustrated in my Patent No. 1,487,833, dated February 21, 1924:, and it comprises a cam 28 on a cam shaft 29 journalled in the loom frame and operating against a roll 30 carried by an arm 31 extending rearwardly from the lay, the cam being so shaped that as the high portion thereof acts against the roll 30 it raises the arm 31 and swings the lay forwardly While when the low portion the high portion of the cam to give the lay its backward movement while the roll 30 is on the low portion of the cam.
I have provided herein means actuated by the cam shaft 29 for giving rotative movement to the pulley 24:. Said pulley is shown as having a pinion 36 rigid therewith which meshes with a gear segment 37 pivoted on the loom frame at 38. Said gear segment has an arm 39 extending therefrom which is connected by a link 40 with a crank arm 41 fast on the cam shaft 29. The relation between these parts is such that the rotation of the crank 41 will give an oscillatory movement to the gear segment 37 and as this gear segment meshes with the gear 36, such oscillatory movement will cause a rotation of the pulley 34 first in one direction and then in the other thereby to cause the knife 10 to reciprocate back and forth across the loom. I V
This construction causes the knife to move across the loom during each half rotation of the shaft 29 and, therefore, during a complete rotation of said shaft 29 the knife will move from one side of the loom tothe other and back again thus making a complete double reciprocation.
The cam 28 is arranged to cause the lay to have two forward beats for each rotation of the cam shaft 29 and, therefore, with this arrangementtheknife 10 will be carried once across the loom for each forward beat of the lay.
I claim:
lna double-pile fabric loom, the combination with a lay having a rearwardly-extending arm, of a cam shaft, a cam thereon engaging said arm'and operating therethrough to move the lay forwardly, a knife-supporting member situated in front of the fell of the cloth being woven, a knife slidably mounted on said supporting member and movable from one side to the otherrofvthe loom, a rotatable pulley, a flexible connec-,,
tion passing around the pulley and having its ends connected with the carriage, a gear rigid with the pulley, an oscillating gear pivoted to the loom frame, and a crank on the cam shaft connected to said oscillating gear and acting to oscillate the gear as the cam shaft rotates.
In testimony whereof, I have signed my name to this specification.
