CONTROLLING MEANS FOR TAKE-UPS FOR LOOMS.

Specification of Letters Patent.

Patented Oct. 1, 1907.

Application filed April 29, 1907. Serial No. 370,852.

To all whom it may concern:

Be it known that I, MARTIN MoUL, a citizen of the United States, residing at Hanover, county of York, and State of Pennsylvania, have invented certain new and useful Improvements in Controlling Means for Take-Ups for Looms, of which the following is a specification.

My invention relates to controlling means for takeups for looms.

The present invention has for its object the provision of a novel automatic clutch shifting mechanism for use with the take-up mechanism of looms, particularly those used in weaving wire fabrics, its function being to automatically shift the clutch controlling the take-up winding roll according to the movement of the tension mechanism so that the take-up roll will be antomatically started or stopped according to conditions of operation.

The invention is set forth fully hereinafter and its novel features are recited in the appended claims.

In the accompanying drawings:Figure 1 is a side elevation; Fig. 2, an end elevation, partly in section, and Fig. 3, a detail perspective of the rocker arms and drop-weight.

Only so much of a wire loom is shown as will enable the present invention to be fully understood.

The loom frame 1 has pivoted thereto at 2 arms 3 (only one of which is shown) which support the tension roll 4. A weighted lever 5, pivoted to frame 1 at 6 and resting on a lug 7 on arm 3, completes the tension mechanism. The take-up winding roll 8 is journaled in frame 1 and carries a worm-wheel 9 which meshes with and is driven by a worm 10 carried by a shaft 11 having a clutch part 12 fixed thereto. A drive shaft 13, which revolves continuously, has loosely splined thereto at 14 a clutch part 15 which revolves with the shaft 13 but is capable of being shifted into or out of engagement with clutch part 12 by a yoke 16 which is secured to a shaft 17 journaled in frame 1.

Secured rigidly to shaft 17 is a rocker having the arms 18 and 19 provided, respectively, with the fingers 20 and 21. Loosely mounted on shaft 17 is a dropweight 22 which is adapted to play between the fingers 20 and 21 and, by its engagement with them, rock the shaft 17 one way or the other. Loosely mounted on the shaft 17 and located next the drop'weight 22 is a rocker having the arms 23 and 24 provided, respectively, with fingers 25 and 26 adapted to be made to engage opposite sides of the drop-weight 22 to shift it one way or the other. A red 27 connects the arm 24 to the lever 5. Secured to shaft 17 is an arm 28 to which a hand-lever 29 is fastened at 30, said hand-lever extending to the front of the machine in convenient reach of the operator. A link 31, pivoted to the lever 29, has a pin-and-slot connection 32 with the lever 5 permitting said lever 5 to play up and down to normal limits without shifting said link.

While requirements of operation are being satisfactorily fulfilled, the clutch parts 12 and 15 are engaged and the take-up roll 8 is in rotation but if the tension becomes too great the lifting of the weighted lever 5 causes rod 27 to rock the double-rocker 23-24 sufiiciently to cause arm 24 to engage and lift drop-Weight 22 beyond its position of equilibrium and it then drops by gravity to the position shown by full lines, carrying with it the double-rocker 1819 and rocking the shaft 17, thereby disengaging the clutch parts 12 and 15. When the tension decreases, the dropping of the lever 5 causes rocker arm 23 to engage with and return the drop-weight to its former position during which movement the drop-weight carries the rocker 1819 with it, thus turning shaft 17 back to its former position and reengaging the clutch members 12 and 15, causing rotation of the takeup roll.

In case the lever 5 fails to act, the operator may use the hand lever 29 to control the rotation of the take-up roll by shifting the clutch. The link 31 also serves to shift the clutch in case the drop weight fails to act.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:-

1. In a controlling means for loom take-ups, the combination with a movable tension mechanism, and a clutch for controlling the take-up, of a clutch shifter, a dropweight shifter, an operative connection between the movable tension mechanism and the drop-weight shifter, and a drop-weight mounted loosely in relation to the drop-weight shifter for loose movement in relation thereto which is adapted to cooperate with the clutch shifter.

2. In a controlling means for loom take-ups, the combination with a movable tension mechanism, and a clutch for controlling the take-up, of a clutch-shifter, a pivoted drop-weight adapted to cooperate with the clutch-shifter, a double rocker having arms adapted to engage the dropweight to move it in opposite directions, and an operative connection between the movable tension mechanism'and the double rocker.

3. In a controlling means for loom take-ups, the combination with a movable tension mechanism, and a clutch for controlling the takeup, of a rock-shaft having an operative connection with the clutch, a double'armed rocker secured to the rocleshaft, a drop-weight pivotally mounted on the rock-shaft and adapted to play between and engage the arms of the rocker aforesaid, a drop-weight shifter, and an operative connection between the dropweight shifter and the movable tension mechanism.

4. In a controlling means for loom take-ups, the combination with a movable tension mechanism, and a clutch for controlling the takemp, of a rock-shaft having an operative connection with the clutch, a doublenrnled rocker secured to the rock-shaft, a drop-weight pivotally mounted on the rock-shaft and adapted to play between and engage the arms of the rocker aforesaid, a dropweight shifter, a doublehrmed rocker loosely mounted on the shaft whose arms lie on opposite sides of and are adapted to engage the drop-weight, and :in operative connection 10 between the lust named double rocker and the movable tension mechanism.

In testimony whereof, I hereunto nihx my signature in presence of two witnesses.
