FASHIONING ATTACHMENT FOR KNITTING MACHINES Filed April e, 1935 5 Sheets-Sheet 3 2]- @g /25 25/55 fg ZZ L5V13/'\|||Hun|wl"I Hill" Z0/\ 24/ y Il Patented June 11, 1935 FASHIONING ATTACHMENTFOR KNITTING- MACHINES-1 This invention relates to improvements in knitting machines and it is the principal objectof my invention to provide `a transfer attachment for such machines according to which material 5.. thread is transferred from one kbed to the other inorder to transfer during the operation ofthe knitting machine automaticallyI vcertain designs on the goods which heretofore had to be formed in separate machines or by hand.

My attachment can be used with any type of machines principally also with jacquard machines to fashion in any design by means of the needles pushedout of the horizontal needle bed according to the jacquard pattern coeoperating l with the transfer jack needles and the verticalv cylinder needles.

Another object of my invention is of a knitting machine attachment'. equipped with a cam development with which'thetransfer'jacks f co-operate to transfer the .thread from the'h'orizontal cam-controlled needles to the vertical needles for fashioning adesired design on `the knitted goods. Y Y

It will be evident that my attachment can be used in the above outlined manner withany type of needle bed arrangement in any'type of knitting machines which has more than one needle'bed, and'that the angle at which the needle beds are arranged in the various type 4of knitting machines may vary depending on the style of machine with which the attachment is to'be used. Still another object of' my invention ist the provision of a transfer attachment for knitting machines equipped with means for holding the throats of the horizontal needles open until they are closed during their dropping into a-r'ecess-'of the cam to allow a transfer of the thread tothe vertical needles. 4A further object of my invention is the pr'ovision of a thread loop holder or opening device allowing the opening of any number of threads in any section of the needle bed according toa'predetermined selection for transfer to the cylinder needles. A still further object of my invention is the provision of an attachment for knitting machines by means of which I can make a Jersey sweater withv a ribbed bottom part in one piece or any other type of fashioned design on the same.

Further objects of my invention are the pro,- vision of a lock for the transfer needles operated by the pattern chain, and the provision of a transfer attachment for knitting machines of comparatively simple and inexpensive constructiom'yet durable and highly efficient in operation and-althe provisionk lowing 'a ymounting on .any of :theknitting ma-` chines in `use at present without the necessity of material andexpensive changes.

These and other objects-of my invention will become more fully known as the description thereof 1 proceeds 'and'. will' then be -specifically defined in the 'appended claims. VWhile I have kdescribed my attachment'as-use'd' with machines having stationary` beds and :revolving lheads in' which the-cams move,` it willbeclearthat the same may also be used 'with machines having stationary heads and' revolving beds in which the cams are stationary, the only difference being that the parts will operatein'reverse manner.` f

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:

2. A transfer attachment for knitting machines of the character described including their needle beds, comprising an additional needle bed for a plurality of fashioning jacks on said attachment arranged to co-operate with the selected number of knitting needles of the machine, cam arrangements in said attachment to gradually transfer the thread from said knitting needles to said fashioning jacks, a loop` holder for holding the thread during the transferring of the thread from said jacks to the vertical needles, a cam lto swing the jacks during the transfer of the thread into alignment With the knitting needles, a means for returning the fashioning jacks into their normal position after the transfer of the thread to the vertical needles to permit the completion of the stitch by said vertical needles, and alocking paWl pivotally attached to one of the cams controlling the operation of the jacks for holding the jack needles inoperative if no fashioning operation is desired;
