TAKE-UP MECHANISM FOR LOOIVIS.

SPECIFICATION forming part of Letters Patent No. 769,580, dated September 6, 1904.

Application file December '7, 1903. Serial No. 184,181. (No model.)

To all 1071/0711, it nmy (ID/b08777 Be it known that I, GUSTAVE E. ANDERSON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Take-Up Mechanism for Looms, of which the following is a specification.

The object of my invention is to so construct take-up mechanism for looms that any desired change in the speed of take-up, and consequently any desired change in the number of picks of weft-thread in an inch of woven fabric, can be effected by change of one of the spnr-wheels in the train of gears whereby movement is transmitted from the ratchet wheel forming the primary member of said train to the wheel on the shaft of the take-up roll, the wheels of the train being such that the number of teeth in the change gear-wheel will represent the desired number of picks to the inch.

In the accompanying drawings, Figure I is a side view of suflicient of a loom to illustrate my invention; and Fig. 2 is a view of the same. partly in end elevation and partly in section.

1 represents part of one of the side frames of the loom, and 2 part of the swinging lay, which carries a pin 3, engaging with a slotted lever 4, the latterbeing hung to a pin 5, which is adjustable longitudinally in a slotted lug 6 on one of the bars of the frame 1. In addition to the slot 7, which engages the pin 3, the lever A has a slot 8 for the reception of a pin 9, which is adjustable in said slot 8 from and toward the fulcrum-pin 5 of the lever, and said pin 9 carries a pawl 10, which engages with the teeth of a ratchet-wheel 11, the latter being mounted so as to be free to turn upon a stud 12, which is secured to and projects from a slide 13 on the side frame 1 of the loom. Vertical adjustment of this slide 13 on the loom-frame is in the present instance effected by providing said frame with a vertical slot 14 for the reception of the bolt 15, whereby the slide is secured to the frame, a lug 16 on the slide also entering said slot, as shown in Fig. 2, so as to insure the proper guidance of the slide in its vertical movement.

I-Iung to the fulcrum-pin 5 of the lever A is a detent 17, which engages with the teeth of the ratchet-wheel 11 and prevents back movement of the same. Secured to the hub of the ratchet-wheel 11 is a pinion 1S, and meshing with the latter is another pinion, 19, which is free to turn upon a stud 20, secured to and projecting from the slide 13, said pinion 19 meshing with a spur-wheel 21, which is secured to a shaft 22 free to turn in a hanger 23, secured to the frame 1, as shown in Fig. 2, said shaft 22- also having a spur-pinion 24:, which meshes with a spur-wheel 25 on the shaft of the take-up roll 26.

The spur-wheel 21 constitutes the changewheel of the gearing and has as many teeth as the desired number of picks per inch in the fabric to be woven. The ratio of the spurwhcel 25 and pinion 2%. being fixed and the number of teeth in the ratchet-wheel being also known, all that remains to be determined in order to permit of the use of a changewheel of the character described is the relation of the circumference of the take-up roll' 26 to the number of teeth in the pinion 18, the pinion 19 being a negligible quantity, since it is employed simply for causing the proper direction of rotation of the take-up roll and has no effect upon the speed of movement of the same. Assuming that G represents the circumference of the take-up roll, P the number of teeth in the pinion 18, R IN the number of teeth in the ratchet-wheel, and R the ratio between the wheels 2% and 25, the

same number of teeth as the number of picks per inch in the fabric which is being woven, substantially as specified.

3. The combination in take-up mechanism for looms, of the take-up roll and the gearwheel thereon, a ratchet-wheel constituting the primary member of the gearing, a pinion secured to saicbratchet-wheel, gearing for transmitting motion from said pinion to the take-up roll, one of the members of said gear- 4 ing being a change-wheel, a slide carrying the ratchet-wheel and its pinion and means for adjusting said slide from and toward the axis of said change-wheel, substantially as specified.
