H. HILDEBRANDT ADJUSTABLE STOP MECHANISM FOR-YARN MEASURING SPOOL WINDERS Filed. Aug. 25, 1928 Patented Apr. 22, 1930 UNITED STTES PATENT OFFICE,
LOUIS I-I. HILDEBRANDT, OF AMSTERDAM, NEW YORK, ASSIGNOR 'IO COLLINS LOOM WORKS INC., 015 AMSTERDAM, NEW YORK, A CORPORATION 01E NEW YORK ADJUSTABLE STOP MECHANISM FOR YARN-MEASURING SPOOL WINDERS Application filed August 25, 1928. Serial No. 302,129.
This invention relates to winding devices, To the end of the shaft B of the measuring particularly those adapted to wind tuft yarn spools such as are used on AXminster looms.
The object of this invention is to provide a readily adjustable stop mechanism for use on winding devices for setting frames and similar machines; a stopmechanism which will automatically stop the winding mechanism as soon as the'desired length of yarns (be it the length which will fill the spool, or but a fraction of that length) is wound thereon. This present invention is an improvement over the stop mechanism disclosed in United States Patent No. 1,185,633, issued June 6, 1916, to Charles H. Collins, and which was designed to insure the winding of a definitely fixed amount of yarn upon each spool wound.
The manner in which I have accomplished my object is illustrated in the accompanying drawings which show my improved adjustable automatic stop mechanism as associated with the measuring device disclosed in the above mentioned patent to Collins; Fig.
- 1 being atop plan view, and Fig. 2 a front elevation, a part of the frame and one of the measuring rolls of the Collins device shown.
Referring to the drawings, Brepresents a usual measuring roll such as isadapted to conbeing tactwith, and be driven by the longitudinal movement of the yarns as they are drawn onto the spool in any usual manner, B represents the shaft of the measuring roll, and F a por- 7 tion of the frame of the spool winding machine provided with measuring rolls.
2 is a'stud on which is journalled a disk 3, having a notch 4 formed in the periphery One end of an arm 7 is pivoted as at 8 toa suitable support formed on or secured to the e frame F of the spool winder and yarn measuring device, the other or free end thereof having pivoted thereto or therein a. bellcrank lever 9, the downwardly projecting short arm 10 of which is adapted at times to enter the notch 4 in the periphery of the disk 3 over'which it is located.
The top of the table 15 is divided by regularly spaced radial graduations 20 at least a part of which are identified by suitable in .dicia; and on the top of this table is a pin or projection 21 adapted to strike the side of the upper end of the lever 23 which is fulcrumed at 2 1 to the frame F or a suitable bearing secured thereto. The lower end of the lever 23 has a side projecting part 25 adapted to slip under the arm 7 when it is raised to draw the short arm 10 of thebell-crank lever 9 free of the notch 4 in the disk 3 and from contact with the periphery thereof. The lever 23'is controlled by a spring 26 the tendencywhereof is to force the lower end of the lever toward the arm 7 and the projection 25 to slip under it. A stop 27 limits the movement of the lever 23 under the urge of its controlling spring. a i i v The outer or long arm of the bell-crank lever 9 is connected, as by a rod 30, to the stopping mechanism of the spool winder (not shown), and which it is adapted to actuate.
The operation of my adjustable stop mechanism is as follows: v
The devicebeing at rest, force is applied t withdraw the worm gear 13 from engagement with the worm 12 (in opposition to the spring 18), which will free the table or dial a 15 so that it may easily be rotated counter clockwise to withdraw the projection 21 from contact with the upper end of the lever 23 for any desired distance. Thegraduations on the table 15 indicate the amount of yarn,
in feet which will be'laid upon the spool by the spool winder during the time it is being rotated from the set to the kick off position. For instance: in the drawing the table is illustrated as being setat a, which means that four feet of yarn will be wound upon the .spool before the projection 21 will travel to the kick d position andthe zero mark be in front of the pointer 31.
After the table has been rotated backward and set at the desired point the arm 7 is raised until the projection 25 slips thereunder and so holds the arm 10 out of the notch 4 and-away from the periphery of the disk 3; the worm gear is then permitted to return into engagement with'the-worm under the urge of the'spring 18, and the shifting mechanism or clutch of the spool winder actuated to start arm 7 and permit that arm and the bell crank lever carried on the end thereof to drop, the
short armlO- of said bell crank coming into Contact with the periphery of the disk 3. As the. disk 3 continues-its regular rotation, communicated to it from the measuring roll, the end of the arm 10 will ride the periphery of the disk 3 and eventually enter the notch 24, an just as the lastof the desired length of yarn is laid upon the s ool the long arm of the" bell-crank lever 9 will be kicked up, due to the urge of the disk 3, in the notch a in which theshort end has then come to rest, and so shift the starting-and stopping mechaof the spool winder to the stop position'.
