Application filed February 16, 1923. Serial No. 619,415;

To all whom it may concern: J

'"Be it known that we, KENNETH Howrn and WILLIAM O. TAYLOR, citizens of, the United States, and residents of Norristown and Limerick, respectively, in the county of Montgomery and State of Pennsylvania,

have invented certain new and useful Im= provements in Punch Mechanism for Making Pattern Strips, of which the following 7 is a specification.

Our invention is designed to make pattern bands for controlling operations of a machine such as a knitting machine, wherein a plurality of yarn fingerslare distributed aroundthe needle circle and feed in different colors of yarn to produce striping of the fabric.

In such a machine there may be, say, eight different yarn feeding devices at separated points about the machine, and these different yarns will be in or out of service according to the striped pattern desired. There may be only one in service, or all of the eight feeds may be in service at the same time, or any number between the maxi.- mum and minimum may be inservice, and these'may be in any desired order.

Our invention has been devised to make pattern strips, bands or sheets, which will give any one of the innumerable effects that may be desired, the yarn feeds being thrown in and out in groups or singly.

The machine 18 shown in the accompany ing drawings, in which igure l is a plan view. Fig. 2 is a side view.

Fig. 3 is a sect onal view from front to rear.

Fig. 4 is an end view.

Fig. 5 is a detail.

The machine comprises a series of punches 1, movable vertically in a guide frame 2, overlying the main base frame 3. These punches are pressed upwardly by when either one is forced down, itwwill punch an opening in the'paper strip extending over the die opening. The strip is com posed, preferably, of heavy paper 7, and

prior to its conversion into apattern band s it is providedfalongeaclr margin with a row of feed holes 7 to be engaged by the toothed feed wheels 8, fixed to, or formed in one piece, iththe sleeve '9 fixed to the shaft 9 journaled in the bearings or ears 1O ofthe mainframe. The paper strip is introduced into the machineby sliding it over the plain upper-surface of the base in the direction of the arrow and bringing its leading feed holes, one on each side, in position to be engaged by the teeth of the feed wheels when theseare turned. The strip is guided by upstanding sides 11 of the base. Movement to the strip can be imparted in two" ways, i. e., either step by step, or continuously. I

In the step by step movement,'the steps can be made of any desired length to suit the pattern desired. I

Thisfeeding mechanism comprises a ratchet wheel 12 connected with the shaft of the feed wheels so as to turn the same,'but the connection is such that the feed wheels can be rotated independently of the ratchet. The ratchet is therefore loosely mounted on the shaft of the feed wheels and it is located at the left hand side of the machine at a point outside the bearing for the feed wheel shaft. It is engaged by ,a s ring pawl 13 carried'in' a casing 14 on the finger lever 15 which is mounted to turn-0n the shaft of the feed wheel, it' lying-between the ratchet wheel andthebearing of the shaft. shaft 9 by'a spring pin 16 'enga'ging a hole 17 in the side face of'th'e ratchet. This springpin is carried *by'an arm 18 fixed to the feed wheel shaft outside the ratchet wheel, The spring pin has a finger button 16 by which it can be retracted to free it from the ratchet, whereupon the arm and shaft maybe turned toturn the feed wheels for advancing the strip through the machine continuously, as may be desired. f

When the strip is advanced by the pawl and ratchet mechanism, step by step, by working the finger lever back and forth, the

length of the. step movejrnent maybe'long The ratchet wheel is attached to the V 'or any desired number of ratchet teeth.

During this movement of the lever, the ratchet Wheel will be held bythe detent 21.

Having counted air the number of spaces" that he desires to advance the paper sheet, by moving the finger lever back over' the desired number of ratchet teeth, the operator will draw the finger lever towards himself at the front of the machine until it reaches normal position against the "stop. .The ratchet wheel will, therefore, turn and advance. the paper to itsnew position, and here it will rest while it is being punched. It may be punched b'yeither one, all, or any intermediate number of punches, by depressing the desired ones of the punch levers 4. There are nine of these shown, one markedC, standing for the counter which controls the operation of mechanism which counts the number of articles produced by the machine, and the others are ,numbered from 1. to 8, corresponding to the number offeeds on the machine. If only the 1 key is depressed whilethe strip is standing in the position to which it has just been moved, there willbe onl'y one opening in the completed strip on this imaginary line extending acrossthe strip, and hence the pattern strip, when, placed in the knitting machine, will make "a change only" at the one feed, all the otherseven feedsremaining as they were. If the operator, however, had pressed down another key; .or. keys, additional to that numbered 1, while the paperstrip is standing at rest in the position to which it has justbeen moved,- these other openings will be madein the strip in line across the same and with the hole first punched in this line, so that when the strip isused as apattern band in the knitting machine, changes will take place at all of those feeds corresponding to the position across the strip at which said holes .are punched, and if eightholes are punched,

is then; used as a handle to turn othearm 18 and shaft 9 with the wheels 8 to feed the stripas'niay be desired. In this continuous aefiidn; t e alt ;.1eet..irll e w ll: r n tetionary. The paper strip is kept in feeding contact with'the feed wheel '8 by a guide plate20, Fig." 3.' This is pressed by leaf springs 20 attached to the lower side of the frame at 20". The plate 20 is slotted at 22, Fig. 5, .for the passage-of the teeth of the Wheels 8 I I The finger levers t are held up in normal positionbythe spring-pins 1 and are lined up against the cross bar 23.

The sle' ve'ii'," addition to having the toothed wheels 8 thereon, has an untoothed wheel 8 to engage theicentral part of the strip and perform a feeding" action at this point, in connection with the spring presser plate. p

\ At therearv of the machine a cutting knife 24 is pivoted at 25 to out the paper strip transversely, to the desired length, inf forin ing the pattern band. This knife. blade is pivoted to the fixed blade member 24* which is screwed to the rear crossbar of themai'n' "frame. I A guide comb for th elfingerlev'ers is shown at 26. 7 I g r The base frame .is open from side to side where the feed wheels are located, and the spring pi esser plate extends from sidetn side to afford a bearing for the paperfstrip.
