TAKE-UP MOTION FOR CIRCULAR-KNITTING MACHINES.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Original application filed. May 17, 1912, Serial No. 697,861. Divided and this application filed October 29,

To all whom it may concern Be it known that I, HARRY A. HOUSEMAN, a'citizen ofthe United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have inventedanew and useful Improvement in Take-Up Motions for Circular-Knitting Machines, of which the following is a full, clearyand exactdescription, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide means for taking up the fabric as it is fed from the knitting mechanism of an ordinary circular machine.

The nature of the invention will be best understood by reference to the accompanying drawing, which represents the take-up mechanism mounted on the frame of the machine and in operative relation with the knitting head.

a is the frame of the machine, 6 the upper bed plate. Projecting from the bed plate is arranged a knitting head 0, which is shown only in a general way in the drawings and may be assumed to diagrammatically rep resent the knitting mechanism from which the fabric 00, shown in dotted lines, is fed.

Thewinder or take-up mechanism is supported from the bracket cl in the following manner: The take-up roller 6 turns in bearings in the bracket d. A presser roller f is supported from a link 9 carried by a fixed arm h extending up from the bracket d. A weighted frame j is pivoted near its lower end on the bracket 0?.

As the knitted fabric passes from the knitting head 0, it engages the weighted frame j, and thence passes under the take up roller 6, thence up between the latter and the presser roller f and thence around the latter and down to the receptacle for the stockings. Fast to the shaft of roller 6 is a ratchet is. Loose on the shaft of roller 6 is a half disk on carrying a pawl n engaging the ratchet 70. On this half disk at is a crank pin from which extends a rod r having a notched end, the rod 1" resting, between Serial No. 728,365. 7

the pawl n and ratchet 0, and the roller f.

This causes the free end of rod r to be gradually el'eVated-until it is brought into line with the kicker arm n. The latter, in its forward movement of reciprocation, then engages the rod 0* and restores the half-disk m to its original position (the pawl a slipping back upon the teeth of the ratchet 0), thus lifting the weight to its upper position. The weight again starts its descent and continues to descend until it is again lifted by the kicker-arm o.

The subject-matter of this application is also described, but not claimed, in an application filed by me May 17, 1912, Serial No. 697,861 of which this application is a division.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. In a circular knitting machine, the combination with the knitting mechanism and a winder adapted to feed the knitted fabric from the knitting mechanism; said winder including a take-up roller, a weighted member, and pawl and ratchet mechanism between said member and roller; a reciprocating kicker arm and means'to opcrate the same, and a rod disconnected from the kicker arm and connected with said member and normally out of operative relation with said kicker arm but adapted, as the weighted member turns in the feeding of the fabric, to be shifted by said weighted member into operative relation with the kicker arm, whereby thelatter actuates the rod and restores the weighted member to its starting position.

2. I11 a circular knitting machine, the combination with the knitting mechanism and a winder adapted to feed the knitted fabric from the knitting mechanism; said winder including a take-up roller, a weighted member turnable on the axis of the roller and pawl and ratchet mechanism between said member and roller; a rod connected with said member, a reciprocatory kicker arm disconnected from said rod and means t0 epera'te the same, and a fulcrum, engaging said rod and. causing the end thereof to be elevated as the member .turns until the rod is brought into position to be engaged by the kicker arm in one of itsiecipro'cations, thereby permitting the kicker arm to actuate the rod and restore the Weighted 'mem bei; to its starting position. p

3. In a circular knitting machine, the combination With the knitting mechanism and a inder adapted to feed the knitted fabric from the knitting mechanism; said Winder including a take'tip roller, a Wei hted member turnable on the axis of the roller, a ratchet fast ion the axis; of the roller, a pawl on the Weighted member engaging said ratchet, whereby the Weighted member,

through the medium of the pawl and ratchet, turns the takegup roller as the fabric feeds; a reciprocatory kicker arm and means to actuate it, a rod pivoted at, one end on the Weighted. member and fulcrumed between its ends and havinga notched free end, whereby as the pivoted end of the rod is depressed during the feeding action of the Weighted member its notchedsfree end rises until it is brought into operative relation with the kicker arm. V

In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 25th da f Qctober, 1912.
