Description

Patented June 27, 1944 UNITED STATES., PATENT'. OFFICE Thomas Callaway of Georgia Application November 5 Claims.

This invention relates to looms and is illustrated as embodied in the type of loom used in the manufacture of fabrics where fringes are required. Y

An object of in the fabric where no filling is desired.

Another object of this inventio-n is to provide a mechanism for spacing fringes.

A further object of this invention is to actuate the center filling fork to allow passage of an empty shuttle during the forming of the empty spaces. I

A still further object of this invention is to relieve friction of speeding-up of the take-up mechanism.

With these and other objectsV in view which will appear as the descriptionv proceeds the inthe combination and arrangedescribed and Vset forth.

The drawing is a'perspective of a loom showing the invention.

In the drawing is shown a loom equipped with a box motion. The loom is illustrated as having the usual frame 2, lay 4, reed a plurality of shuttle boxes I0, I2, |4,y and l5. The boxes are supported by a box lifter rod I8 which is vertically movable by` means of the pive View of a portion otally associated rod 28, the upper part of which l is pivotally connected to arm 22. Arm 22 is the 1i' usual type arm used on the loom of this type and is vertically actuated by mechanism (not shown) attached to arm 22 by the members 24 and 26.

A rocker shaft 28 has support 30 and arm 32 rigidly connected to it. Arm 34, having pawl 36 associated with it, is pivotally mounted on shaft 38 andis adjustably connected by rod 40 to arm 32. Also on shaft 33 is rachet gear 42 and spur gear 44. Gear 44 is in mesh with gear 46, which has apinion 48 in mesh with the take-up gear 50.

A pawl 52 is shown pivo-tally attached to the center lling stop motion 54, which is partially shown and is rigidly attached to the cross beam 56.

Corning more particularly tothe present invention, arm 58 is adjustably attached to rod I8 by means of a set screw such as 60. Lever 62 is pivotally connected on shaft 38 and has pivotally attached to it cross-piece 64 which carries rod 66. Rod 66 is held up by support 68 and extends through guide 18. Blocks 12 and 14 are adjustably xed on rod 65 by means of set screws 16 and 18. Pawl 80, pivotally attached to arm 62 actuates the rachet gear 42, which is fixed on this invention is to form spaces the loom beam during the 6, reed cap 8 and c 0. Ott, Jr., La Grange,

(ci. 13a-24) shaft 38. A spring 82 has one of its ends `attached to the guide'10 and the other end connected to the upper portion of arm 82. A cord or cable 84 is connected to arm 22, the said cord or cable extending partially around the grooved roller 86, which is rotatably mounted on the fixed shaft 88 extending from the loom side 2. From the grooved roller86 the cord or cable 84 extends to and partially around the grooved roller 89, rotatably mounted on shaft 80. The shaft 90 is rigidly xed to the support 92 which is attached to the top 0f lloom side 2. From the grooved roller 88 the cord or cable 84 extends and is fastened to the loom-beam brake-lever 84. The weight 86 is attached to the brake lever 94 by means of the rod 98. Also connected to the lever 22 is-another cord or cable |00, this cord or cable extends partially around the rotatably mountedroller |02 on fixed shaft |04 extending from the loom side 2. From the grooved roller |02 the cord or cable |00 extends under the loom tothe eye |06, which is screwed into the floor. Through the eyelUB the cord or cable .extends and is attached to the lower end of spring |08. The upper end of spring |08 is fastened to a cord or cable ||0, vwhich extends and is attached to the pawl 52. In operation, arm 22 is'moved vertically by the usual box motion actuating mechanism (not shown) extending from arms 24 and 2E at any desired intervals. This movement causes rod 20, which is pivotally associated with arm 22, to also have the same vertical movements and to impart the movements to rod |8 at the desired intervals. Rod I8 actuates the shuttle boxes Ill, |2, I4 and. I6', and causes the boxes to be placed in the desired position at the proper time. Only when rod I8 is lifted vertically to raise the box containing ,the empty shuttle (not shown) in shuttle box ||l into position to be thrown across the lay 4, arm 58 is also raised and comes into contact with rod 66 between blocks 12 and 14. At this time the usual center filling fork is rendered inoperative. As the lay oscillates backward and forward, arm 5B, by means of blocks 12 and 14 causes rod 66 to be moved backward and forward, this in turn oscillating lever 62. As lever 62 is oscillated pawl 80 comes into contact with and rotates rachet gear 42. Gear 44 on shaft 38 is driven by rachet gear 42 and is the driver of gear 46, which has a pinion 48 in mesh with and drives the take-up gear 50.

Also when the arm 22 is raised the end of the cord or cable 84 attached to arm 22 is raised; this action raises the brake lever 94, thus releasing the friction on the loom beam H2 during the intervals that the take-up mechanism is speededup.

The end of cord or cable attached to arm 22 is also raised when arm 22 is raised thus making ineffective the center filling stop motion to allow passage of the empty shuttle during the intervals that the spaces are being formed. There is sufficient slack in cables 84 and I 0.0 so as to release the Warp friction and make the stop motion ineffective only when box I0 is in position.

While only one illustrative embodiment has been shown and described it is not intended that the scope of the invention be limited to the form shown, nor otherwise than by the terms of the appended claims.
