UNETED STATES PATYENT OFFICE.
ARTHUR E. THOMAS, OF WORCESTER, MASSACHUSETTS, ASSIG'NOR TO GBO'MIPTON & KNOWLES LOOM WORKS, OF WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
WHIP ROLL FOR LOOMS.
Application filed February 11, 1924.
To all whomv it may concern:
Be it know that I, ARTHUR E. THoMAs, a citizen of the United States, residing at Vorcester, in the county of lVorcester and State of Massachusetts. have invented a new and useful IVhip Roll for Looms, of which the following is a specification.
This invention relates to whip rolls for looms and more particularly to improvements in yielding whip rolls designed to prevent thick and thin places in the cloth.
In weaving certain types of fabric it is desirable to have a large supply of warp, necessitating large beams and beam heads.
" Under these circumstances the whip roll is located very close to the beam head, and interferes with the latter when a new warp is to be placed in the loom. To facilitate handling the warp under such conditions I have provided for raising the whip roll to a position where the beam will pass without interference.
Accordingly the principal object of my invention is to provide means whereby a. roll of the type mentioned may be used with a very large warp beam, the roll being mounted so it may be swung away from the beam to make room for the removal of the latter.
With this general object and others which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.
In the accompanying drawings, wherein one form of my invention is shown,
Fig. l is a side elevation of part of a loom having my invention applied thereto,
Fig. 2 is a rear elevation of the parts shown in Fig. 1, and
Fig. 3 is a fragmentary top plan view showing parts of my invention in section.
Referring more particularly to the drawings it will be seen that the loom side 10 is provided with an open bearing or pocket 11 which receives the gudgeon 12 of the beam 18. The beam. is provided with heads, one of which is indicated at 14, the head being provided with a drum 15 by means of which friction may be applied to regulate the amount of yarn delivered to the harnesses. Upstanding from the loom side 10 is an arm 16 to which is bolted a stand 17, and as each side of the loom is provided with one of these stands 17 Serial No. 691,931.
and the parts associated therewith, the description given herein will be limited to the structure located on one side of the loom only.
The bearing 18 is formed integral with the stand 17 and has a vertical bore which receives rod 19 by means of wiich the warp stop motion stand 20 may be supported. The upper part of the stand has a roarwardly extending horn 21 which is forked as indicated at 22 to receive the forward end of arm 21 and pin 25 by means of which the arm is pivoted tothe horn.
Arm 24 is provided with a slot 26 in which moves a block 27 through which passes one of the journals 28 of the whip roll 29. The forward end of the arm: is recessed as indicated at 30 to receive the end of compression spring 31 the rear end of which engages block 27 to push the same to the rear end of the slot.
In order to limit downward motion of the arm and whip roll and also support the same the stand 17 is provided with a stop 32 which has two fingers 33 between which the lower edge 34 of the. arm 24 is designed to rest.
As indicated in the drawings, the beam head is of such proportions that when it is to be taken out of the loom the upper part thereof would engage the whip roll 29 unless the latter were mounted so as to move upwardly, as indicated in dotted lines in Fig. 1. The outer portion of the open bearing 11, indicated at 35, necessarily projects upwardly and the gudgeon 12 must be raised sufficiently to clear said projection. Heretofore it has been common practice to remove the stand 1'? from the loom when a new warp is to be replaced but this procedure involves labor and time and also introduces the opportunity of varying the horizontal plane of the warp, indicated at 40, inasmuch as the vertical position of the whip roll is likely to vary with each new setting.
It is to be understood that when the depleted beam is to be taken from the loom. it may be raised without giving special attention to the whip roll, as the latter will swing upwardly when engaged by the beam head, the warp, if still uncut, permitting this motion of the roll. However, there is nothing to prevent the roll from being swing over to the opposite side of the pin 25 if so desired.
It will be apparent from the foregoing that I have provided a very simple means by which the whip roll can be located very close to the warp beam and be moved away from the latter when occasion requires. The stop 32 serves to arrest the downward pull on the whip roll due to gravity and the pressure of the warp.
It will further be observed that in all angular positions of the arm the spring 81 is effective to hold the whip roll and bearing blocks therefor in the same relative position and that although the weight of the whip roll when the arm is moved to the dotted line position indicated at Fig. 1 would act against spring 81 yet when the parts assume operative position as indicated in full lines the spring is relieved from the force of gravity and is required to act against variation in warp only because of the fact that the slot and spring are substantially horizontal.
Having thus described my invention it will be apparent that changes and modifications may be made therein by those skilled in the art without departing from the spirit and scope of the invention and I do not wish to be limited to the details herein disclosed, but what I claim is:
1. In a loom having a frame, a beam to supply warp, a whip roll around a portion of which the warp extends, said roll being movable yield'ngly in the direction in which the warp travels and being held normally closely adjacent to the beam by its own weight and the pressure of the warp and being movable freely from normal position in a direction transverse of the direction of travel of the warp and away from the beam to permit removal of the beam.
2. In a loom having a frame, a beam to supply warp, a whip roll around a portion of which the warp extends, said roll being movable yieldingly in the direction in which the warp travels and also movable transversely of the direction in which the warp travels, said roll being normally closely adj acent to the beam, and fixed stop against which said roll is normally held and from which it may move freely in a direction away from the beam and transversely of the direction of travel of the warp to permit removal of the beam.
3. In a loom, a removable warp beam, pivoted arms above said warp beam, a yielding whip roll mounted for rectilinear movement on said arms, and a fixed stop tolimit downward movement of the arms and roll and holding said roll closely adjacent to the beam, said arms being freely movable upwardly to carry said roll away from said beam to permit removal of said beam.
4. In a loom having a frame, a warp beam mounted thereon and removable therefrom by an upward movement, arms pivoted to the frame, a yielding whip roll mounted for sliding motion on the arms in a substantially,
horizontal line, a stop for said arms to limit downward motion of the whip roll toward the beam and normally locating said roll in he lowest position thereof closely adjacent the beam, said arms being freely movable upwardly away from the stop to carry the roll away from said beam to permit removal of the latter. I
5. In a loom having a frame, a warp beam mounted thereon and removable therefrom by an upward movement, arms pivoted to the frame, a whip roll yieldingly mounted for sliding motion on said arms in a substantially horizontal line, and a stop for the arms limiting downward movement of the roll, the arms being held in lowest position against the stop by the weight of the roll and the pressure of the warp thereon, the arms being movable away from the stop to carry the roll away from the beam when the pressure of the warp is relieved to permit removal of the beam.
6. In a loom having a frame, a warp beam mounted on the frame and removable therefrom by an upward movement, a, whip roll, pivoted means to mount the roll for yielding rectilinear movement, and a stop to limit motion of the roll toward the beam, said roll being normally in lowest position during the operation of the loom and held ins such position by gravity and the pressureof the Warp, said means being movable upwardly to carry the roll away from the beam when the pressure of the warp is relieved and the beam is to be taken from the frame of the loom.
In testimony whereof I have hereunto affixed my signature.
ARTHUR E. THOMAS.
