Patented Feb. 1949 TRAVERSE FEED CONTROL MEANS Henning T. Tornberg, Ridgewood, N. .L, assignor to Modern Plastic Machinery Corporation, Lodi, N. J a corporation of Delaware Application August 30, 1947, Serial No. 771,476

4 Claims.

The present inventionrelates to winding machines, as for instance for threads, and particuv larly to the traverse feed means employed in such machines. I I

An object of this invention to provide a novel I and improved construction for the traverse feed means of winding machines, whereby adjustments are easily made to change the length of stroke of such feed, to accommodate spools of different lengths.

A further object hereof is to provide a novel and improved adjustable traverse feed means of the character mentioned, whichis of simple construction, cheap to manufacture, easyv touse and eflicient in carrying out the purposes for which it is designed.

Other objects and advantages will become apparent as this disclosure proceeds.

In the acompanying drawings forming part of this specification, similar characters of reference indicate corresponding parts in all the views.

Fig. 1 is a front elevation of an embodiment of this invention. Included, is a double acting cylinder whose piston, having a reciprocatory movement, serves as the traverse feed arm, for supporting and conveying the thread. The mechanism is here shown in its condition when the piston is at one end of its stroke or travel. Means are included for adjustment of such stroke.

Fig. 2 is a fragmentary view of Fig. 1, showing the condition of the mechanism when the piston is at the other end of its travel.

Fig. 3 is a fragmentary section taken at line 33 in Fig. 1, showing a frictional device used in this embodiment.

Fig. 4 is a wiring diagramof an electrical circuit employed in this embodiment.

In the drawings, on a frame I5, is mounted a double acting cylinder I6, controlled by a solenoid valve ll. This valve is in circuit with a micro switch l8, and a source of electrical current IS. The cylinder I5, may be actuated, meaning its piston moved, by either oil, water, air or steam.

The numerals 28 and 2| indicate pipes connecting the valve means [1 with the respective ends of the cylinder. The numeral 22 designates the piston rod. The apparatus set forth in this paragraph, needs no further explanation as to construction and operation, as same is well known.

A screw 23, has reduced

unthreaded ends

24 and 25, at which ends it is suspended and slidably mounted through a frame bracket 25 and a device 21, respectively. Said screw 23, is positioned spaced from and parallel to the piston 22. This screw carries a pair of

members

28 and 29 thereon,

33, carries a member 35 secured thereto.

which really are comparative large nuts associated respectively with independently moveable

small lock nuts

38 and 3| therefor. All said nuts are in threaded engagement with said screw 23. It is evident that the respective positions of the

members

28 and 29, along said screw, are manually adjustable.

- One end of the piston rod '22 is interiorly threaded as a nut along the line of its axis to receive a screw 33. The amount of extension of the screw'33 forward of said end of the piston rod 22,

is of course adjustable and its position maintained by a lock nut 34. The forward'end of said screw Said members, are preferably hubbed discs, of a size that the disc portion of member35 travels between and can contact the other of said discs of the

members

28 and 29, respectively.

The micro switch I 8, is of the push-button type, and is positioned on the frame'whereby its push button l8, may be contacted and moved by an end of the screw member 23. The device 21, is intended to hold the screw member 23 in frictional engagement against longitudinal movement by the spring 36 when stressed, but yet, permit such longitudinal'movement of said screw member 23, when caused by movement of the piston 22. Said device 21, includes a pair of blocks 31,- having opposite concave channels through which screw end 25 lies and slides. Adjustment of the screws 38, against springs 39, will determine the frictional grip on said screw member 23, meaning on the latters end portion 25. The other end of the piston 22, may have the bar 40 extending laterally therefrom, which bar carries a suitable thread eye 4|, for guiding the thread 42 along the spool 43, on rotary spindle 44.

To set the apparatus, piston 22 is set to a position for guiding the thread 42 onto and at end A of the spool #3. Screw 23 is manually shifted to push button l8 to a position where the switch I 8 is in closed condition.

Members

35 and 28 are brought in contact, and lock

nuts

38 and 34 tightened. Piston 22 is now moved to a position for guiding the thread onto and at end B of the spool 43. Screw 23 is manually shifted so that push button moves outward and switch it! is in open condition. Member 29 is now brought into contact with member 35, and lock nut 3| tightened. Screws 38 are adjusted. The cylinder 16 is now operated, and discrepancies noted. Adjustment thereof is then made by slight change of position of the

members

28, 29 and 35, until trathe spool 43, is proper.

the member 35 will have contacted member=29;-

as shown in Fig. 2, and switch [8 will be open, causing valve means to direct'operatingmedium to cylinder it through pipe 21, arid pistonwill return to its position as in Fig.1;rwhenthecyclea repeats.

This invention is capable of numerous-- forms and various applications without departing from the essential features herein disclosed. 11. is therefore intended and desired and that the spe- -cific embodiment herein shall-be deemed illustrative and n-ot'restrictive and that the pa-tent shall cover all patentable' novelty herein set forth; reference being had to the following claims rather than to the specificdescription herein to indicate the scope of this invention.
