DEVICE FOR ENGAGING TRANSFER QUILLS AND NEEDLES OF CI RCULAR-KNITTING MACHINES SPECIFICATION forming part of Letters Patent No. 765,385, dated July 19, 1904:. Application filed June 29, 1903. Serial No. 163,517- (No model.)

To aZZ whom it Wttty concern.-

Be it known that I, HARRY A. HoUsEMAN, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Devices for Engaging Transfer Quills and Needles of Circular-Knitting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

In the transfer device now in use the adjustment of the transfer-quills upon the needles depends upon the skill of the operator.

I 5 My invention has for its object the production of a device which will enable the operator readily and without special skill to adjust the quills upon the needles.

My device can be best understood by refer- 2o ence tothe embodiment of the same in the accompanying drawings, in which Figure 1 is a plan View, partly in section, of the transfer device. section on line 2 2, Fig. 1. Fig. 3 is an ele- 2 5 vation of a portion, showing one of the inclined slots. Fig. 4 is an elevation of a portion, showing adjusting slots. Fig. 5 is a perspective view of one of the adjustable pieces. Fig. 6 is a perspective view of the 3 corresponding adjustable piece.

A is the cylinder of the transfer-quill holder, having the grooves a; corresponding in number to the transfer-quills B.

C is a ring for securing the quills B in the grooves a. A portion of the ring C is cut away, and in this cut-away portion rests a piece cof size less than the extent of the cutaway portion. This piece 0 is adjustable along the transfer-ring C by means of the elongated 4 slots 0 c. The heads cl of screws D, which enter the ring C, overlap the upper surface of the piece 0 at these slots, so that by releasing the screws the positions of this piece may be adjusted. The outer face of this piece 0 has the notch or detent 0 The device for engaging the transfer-quills Fig. 2 is a vertical with the needles consists of the following: E is a ringhavingatfourequidistantpointsthefeetF. These feet consist of the inwardly and downwardly inclined portion f, the vertical portion f having the serrations f on the bottom thereof. Through the walls of this ring E are the inclined slots G, G, and G I H is aring resting with a slidable fit within the ring E at two points upon the ring H corresponding to the 5 5 slots G and G The screws g are secured to the ring H, the heads g g* of said screws, being larger than the width of the slots.

Through the slot G a pin g, acting as a handle, secured to the ring H, passes. A portion of the ring at H is partially cut away, and in such cut-away portion a piece it, having the projecting portion A, corresponding to the notch or detent 0 is secured to the ring E. This piece h is adjustable upon the ring E by 5 means of the slots 7& in the ring E and piece it, through which the holding-screws 7L3 pass. As may readily be seen, by moving the pins 9 the ring H is moved up or down.

In practice the transfer-quill-engaging de vice and transfer-quill holder are first initially adjusted with reference to each other and the machine as follows: The transfer-engaging device is placed upon the cylinder of a circularknitting machinesay of the type shown and described in my Patent No. 484,738s0 that the feet F rest between the needle-cylinder and sinker-head, the sinkers entering the serrations f The transfer-quill holder is then entered into the ring E, so that the ring C rests upon the ring H. The ring C is turned so that the projection h of piece it enters the detent 0 in the piece 0. If when in such position the quill'sB do not aline with the needles, either the piece It or piece 0, or both, 5 are adjusted until they do. When the parts are so adjusted for any given transfer-holder and needle-engaging device, no further adjustment is necessary. The ringH initially is in the position shown in Fig. 2 and when the handle 9 is then moved downward in the slot G, which carries the ring C and quills downward, brings them into engagement With the needles.

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

1. A device, for causing engagement of transfer quills and the needles of a knittingmachine, comprising an outer ring, an inner ring adapted to support a transfer quill holder, there being a downwardly-inclined slot in the outer ring, and a projection connected to the inner ring passing through said slot.

2. A device for causing engagement of the transfer quills and needles of a knitting-machine provided With an outer ring, an inner ring adapted to support a transfer quill holder, there being a downwardly-inclined slot in the outer ring and a handle connected to said inner ring and projecting through said slot.

3. A device, for causing engagement of transfer quills and the needles of a knittingmachine, comprising an outer ring, an inner ring adapted to support a transfer quill holder, there being inclined guiding-slots in said outer ring and guiding-pins secured to said inner ring and projecting through said guiding-slots.

4. A device for causing engagement of the transfer quills and needles of a knitting-machine provided with an outer ring, an inner ring adapted to support a transfer quill holder,there being a downwardly-inclined slot in the outer ring and a handle connected to said inner ring and projecting through said slot, there being inclined guiding-slots in said outer ring and guiding-pins secured to said inner ring and projecting through said guiding-slots.
