CAM-RING FOR KNITTING- MACHINES.
SPECIFICATION forming part of Letters Patent No. 561,039, dated May 26, 1896.
Application filed March 27, 1896.
T0 aZZ whom it may concern,-
Be it known that I, LoUIs N. D. WILLIAMS, a citizen of the United States, and a resident of Ashbourne, Montgomery county, Pennsylvania, have invented certain Improvements in Oam-Rin gs for Knitting-lVIachines, of which the following is a specification.
My invention consists in certain improvements in the cam-rin gs for knitting-machines for which I obtained Letters Patent No. 503,920, dated August 22, 1893, the object of my present invention being to permit access to the needles without the necessity of laterally removing the segments having the cams upon which the bits of the needles are supported. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure l is a transverse sectional view of part of a knitting-machine cylinder, camring, driving-wheel, and bed-plate, illustrating my present invention. Fig. 2 is a sec tional plan view of the same on the line 2 2,
' Fig. 1, with the plate which surmounts the cam-segments removed. Fig. 3 is a view similar to Fig. 1, but illustrating part of the camring removed for gaining access to the needles; and Fig. l is a sectional view illustrating a modification of the invention.
A represents part of the bed-plate of the machine, and B part of the vertical needlecylinder secured thereto and having external grooves for the reception and guidance of the needles, as usual. Mounted on the bed is an annular bevel-Wheel D, to which are secured the segments D, carrying the cams whereby the needles of the cylinder B are actuated, these segments being backed by removable filling-blocks a and both segments and fillingblocks being secured to the bevel-wheel D by means of bolts 19. In the patented machine each of the cam-carrying segments was in one piece, and when it was desired to gain access to the needles the bolt securing the segment was withdrawmthe filling-piece a, corresponding to said segment, removed, and the segment withdrawn laterally until its cams were free from the bits of the needles, the segment being then removed vertically in order that free access to the needles might be permitted.
Serial No. 585,120. (No model.)
In reapplying the cam-carrying segment difficulty was frequently experienced in adjusting the needles so as to cause them to again properly enter the cam-groove. Hence in the present construction I make each cam-carrying segment in two partsnamely, the upper part d and the lower part d, the latter being secured to the bevel-wheel D by the bolt 1) and the upper portion cl of the segment being secured to the lower portion (2 by a vertical bolt 1). In case it is desired to inspect the needles the upper half d of any segment can be readily withdrawn without disturbing the lower half and without disarranging the needles or disengaging their bits from the cams of said" lower portion of the segment, the latter being capable of radial Withdrawal in the same manner as the segment of the patented machine, however, if such withdrawal is necessary. By this means proper inspection and repairs can in almost all cases be effected in a very short time, as there is nothing to prevent the ready removal or the equally ready replacement of the upper portion d of the cam-segment. Further than this, the removal and replacing of the upper portion of the cam-segment can be effected with slight vertical movement of the same. Hence there need be but little space between the needle-confining ring f and the shouldered portion 11 at the top of the needle-cylinder.
It is preferable to provide the upper portions d of the segments with the upper cams of the needle-cam race and the lower portions 61 of thesegments with the lower cams of said needle-cam race, although this is not absolutely essential, as part of the upper cams may, if desired, be secured to the lower portions of the segments.
In the modified construction shown in Fig. 4 the upper section 01 of the cam-segment is made in one piece with the filling-block a and the vertical bolt 6 is dispensed with, both the upper section of the cam-segment and the filling-block being released on the removal of the bolt 1). When they are withdrawn, the lower section at of the cam-segment is not radially confined, but there is very little chance of its being accidentally displaced, and even if it is it can be readily readjusted after first lifting the needles, so that its cams can pass beneath the bits of the same.
Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination of the needle-cylinder and its needles, with the surrounding cam structure consisting of cam carrying segments each composed of upper and lower portions detachably secured together, whereby the upper portion can be removed in order to permit inspection of the needles, an outer drive-wheel and means for securing the camcarrying segments to said drive-wheel, substantially as specified.
2. The combination of the needle-cylinder and its needles, a surrounding cam structure composed of cam-carryin g segments each comprising upper and lower portions secured together, an annular drive-wheel, filling-blocks or segments interposed between said drivewheel and the lower portions of the cam-segments, and means for securing said segments to said drive-wheel, substantially as specified.
3. The combination of the needle-cylinder and its needles, a surrounding cam structure composed of canvcarryin g segments, each composed of upper and lower portions, an outer drive-wheel, vertical bolts securing said portions of the cam-segment together, and other bolts securin g the lower portion of each segment to the drive-wheel, substantially as specified.
4. The combination of the needle-cylinder and its needles, a surrounding cam structure composed of cam-carrying segments, each composed of upper and lower portions, an outer drive-wheel, vertical bolts securing said portions of the cam-segment together, other bolts securing the lower portion of each segm ent to the drive-wheel, and fillin g-blocks interposed between said drive-wheel and ca1nsegments, substantially as specified.
5. The combination of the need1e-cylinder and its needles, a surrounding cam structure composed of cam-carrying segments, each composed of upper and lower portions, an outer drive-wheel, vertical bolts securing said portions of the cam-segment together, other bolts securing the lower portion of each segment to the drive-wheel, and fill in g-blocks in terposed between said drive-wheel and camsegments and having a bearing against the outer face of both the upper and lower portions of each cam-segment, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
