Specification of Letters Patent.

original application-filed April 14, 1908, Serial No. 427,074. Divided and this application filed February 26, 1909. Serial No. 480,097.

5 Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Pattern Mechanism for Glove Knitting Machines; and we do hereby declare the following to be a full, clear, and exact descripothers skilled in the art to which it appertains to make andfluse the same.

Our present invention is a. part of a knitting machine more especially designed for knitting the fingers of gloves and consistsof a pattern mechanism thatcan be set for-the Y differentlengths of the fingers of the glove,

and will arrest the operation of the knitting 20 machine when the requisite length oftubular web has been knitted. The knitting machine here referred to is made the subject of application Serial No. $7,074 of which the present application is a division.

The main purpose of our said invention is to enable the operator, after running on the appropriate stitches ofthe previously knitted hand of the glove'and the knitting of the tube for the finger has'begun, to set 30 the pattern mechanism so that the knitting will be automatically stopped when the proper length has been reached, in order that the operator' may give his or her entire attention' to the running on of stitches of another hand on another needle bed.

In the accompanying drawings we have shown the best form'in which we have contemplated embodying our invention and said invention is fully disclosed in the following description and claims' In these drawings, Figure l is a side elevation of our entire machine. Fig. 2 is a top or plan view of the pattern mechanism thereof, and Fig. 3 is.a longitudinal vertical sectionof the same; v

I Inthese-figures of drawing, A is the supporting standard, B is an arm securedto the staridard A for sup'portingthe sectional needle beds forming a part of our machine which are, as shown, straight beds of the' double inclined type.

D is the bed plate of the machme and E is the double inclined cam slide of the machine cotioerating with the needle beds.

In brackets D secured to the underside of the bed plate D, is mounted the power or driving shaft I."-This shaft is provided with a gear 6 which meshes with a gear 7" on a countershaft K. To this latter shaft is secured the crank disk K. Apitman L connects the crank pin of said disk with the cam slide and'gives the necessary recipro- Patented June 20., 1am. I

eating movement thereto. To the end of shaft K opposite that on which the crank disk is secured, a pink is connected so as to act as a crank or the shaft is provided with an eccentric. Said crank pin or eccentrio is connected with a pawl carrying frame.

M pivotally mounted .on shaft N, mounted in extensions of the brackets D In this pawl frame are mounted a shaftMand a rod M On the shaft N are movably mounted a series offive ratchet wheels 1, 2, 3, 4, 5. .Rigidly secured to each ratchet or made integrally therewith is a sprocket carrying a pattern chain N. On the rod M are journaled five, gravity pa'wls The upper end of each pawl is provided'with a in m extending on one side of the pawl. o shaft, M are secured five pawl con-' trolling disks m The disks are of such" size that when the periphery of the same bears upon the pin 'm/ of its corresponding pawl, such pawl will be raised out of engagement with its ratchet, and the vibration of the pawl carrying-frame will not. I

effect any movement of itsratchet'. Each of the disks m has a portion of its periph ery cut away as at m The cut away portion of each is located at a different pointaround the shaft M as indicated in dotted lines on the only disk seen in Fig.3: so that only one pawl and ratchet will'be in opera tion at the same time. On the front side of the machine, the frame M is provided with the index disk m surrounding the end of the shaft M. Y

To the end of the shaft is secured a means for turning the same and associated there with is a pointer turning with the shaft. The means for turning the shaft M may be of any preferred form.' In this instance it .is shown as being-of substantially the form of the wings of a winged nut, to be grasped and turned by the forefinger and thumb of the operator. Five points are marked on "this index disk and are preferably designated to indicate the different ratchets 1, 2,

3,- and 5, the arrangement being such that when the pointeris turned to the mark designated 1, the disk controlling the pawl of ratchet 1, will be in position to actuate such ratchet, and when turned to the mark 2, the ratchet 2 will be operated, and so on.

In the brackets supporting the shaft N is also journaled the shaft 0, on which is rigidly secured the sleeve O having five fingers extending toward the shaft N, one in line with each of the sprockets on said shaft. On each of the sprockets is carried a pattern chain N and a spring 0 is connected to the shaft 0 and the bracket, so as to maintain.

each finger in contact with its pattern chain.

The driving shaft I projects outwardly beyond the bed plate at the front of the machine and upon this projecting part of the shaft is rigidly secured a tapering friction disk 2'. Loosely mounted on the shaft I in close uxtaposition to the disk 2' is the band pulley I having a tapering recess for engaging the tapering disk 2' and forming there with a friction clutch. The pulley I has a grooved hub and two arms or a fork secured to a sliding bar or rod I engage this groove;

The bar I ismounted in the brackets supporting the ratchet shaft N so as to be capable of endwise movement and is provided with a spring a? tending to move the bar to ward the front of the machine. A rod or shaft I is mounted in hearings on the top of the bed plate of the machine and has a downwardly extending arm i the lower end of which is provided with means to engage the rod or shaft I and when desired move it against the force of the spring 2' In this instance the lower end is bent at right angles and extends over the shaft I between two projections extending upward from the shaft. In this instance such projections are formed by two cotters if and The opposite end of the rod or shaft I 'is provided with an upwardly extending arm I by which the rod or shaft can be turned to move the red I rearwardly and force the hand pulley 1 into frictional engagement with the disk 71 to give motion to the driving shaft 1. The rod I is provided with anupwardly extending shoulder or projection a, and a detent 2' is pivoted to the bracket at the front of the machine and adapted by gravity to drop behind the shoulder i when the'machine is set in motion. The end of the detent i extending tothe right of its pivot (see Fig. 3) is in the path of a pin 0 on the sleeve 0 and when the shaft 0 and sleeve 0 are moved against'the force of the spring 0 the pin 0 presses downward on theright hand end of the detent 2', raising its opposite end from engagement with the shoulder i", permitting the spring to more the rod I forward, opening clutch and I be m g machine when it has knitted a tubular web long enough for the thumb of the glove, one for the fore finger, and so on. g

The finger to'be knitted is determined by turning the shaft 1% to bring the pointer on the index to the proper mark when the machine is put in motion by turning shaft I to close. the clutch, and it will then be stopped when the proper length of tube has been completed.

In operating the machine the operator is located at the front of the machine. Supposing that the machine is provided with four needle beds, the operator withdraws the locking bolt of the needle bed immediately in front of the operator and moves a bed to the position desired and applies thereto the knitted web of the hand for the knitting of the desired finger; the beds are then turned to normal position and the bolt 0 permitted to lock them. The bolt locking the spider is then withdrawn and the spider is given one quarter turn to bring the bed to which loops have been applied, into operative alinement between the bed plate D and plate I) and have the same locked in gagement with pulley I and permitting the detent 2'- to drop behind the shoulder 5 The machine now knits the finger and during this interval of time the operator applies another knitted web to the needles of the needle bed immediately in front. When the machine has knitted the finger to the length determined by the pattern'chain in motion'at that time, the user of the same stops the machine. The spider is then turned to bring the needle bed to which a knitted web has been applied, into position and the operation isrepeated.
