ALBERT E. STEWART, F FRANKLIN, NEW HAMPSHTRE, ASSTG-NOR T6 ACME KNITTING f MACHINE & NEEDLE COMPANY, A C(lRPOB-ATION OF: NEW HAMPSHIRE.
Be it known that I, ALBERT E. STEWART, a citizen of the United States, residing at Franklin, in the county or- Merrimackand State-of New Hampshire, have invented certain new and useful Improvements in Cam- Cylinders for Knitting Machines, of which the following is a specification, reference "being had to the accompanying drawings,
forming part thereof;
This invention has reference to improve 'ments in cam cylinders for knitting machines and particularly to the stitch cams of saideylinders and parts related to-said stitch cams whereby the needles are guided.
One object of this invention is to so construct a cam cylinder for a knitting machine that the needles may be leveled, that the butts of "the needles may pass the stitch cam without being acted upon thereby.
I Another object of the invention is to im-' stitch cam.
The invention also consists in such other novel features of construction and combination -of parts as shall hereinafter be more fully described and pointed out in the'claims.
Figure 1, represents a vertical sectional view of the cam cylinder of a knitting machine as taken on line 1-1 Rig. 2, illustrating this invention. Fig. 2, represents a plan view of portions of a cam cylinder for a knitting machine having my improvement but in other respects of any well known construction.
Similar characters of reference designate corresponding parts throughout.
In the operation of a knitting machine it is sometimes desirable to level the needles, that is to permit the movement of the butts of the needles 'in' their circular path without vertical movement of the needles, as, for instance, in transferring from the knitting of the leg of a stocking to the top thereof. In carrying my invention into practice I accompli'sh this leveling of the needles by dlvidnig both of the stitch cams in parts of which Specification of Letters Patent.
CAM-CYLINDER FOR KNITTINGJlEAfiHINES.
Application filed august as, 1913. swarm. verses.
the lower parts or members are fixed while the upper parts or guide members, together wi th the top center cam are so mounted that said gulde members of the stitch cams and 7'.
the top center cam can be simultaneously retracted out of the path of the needle butts whereby said needle butts may, in the relative rotary movement of the cam cylinder and the needles, ass the stitch cams with-' out being guided vertically thereby,
As shown in the drawings 5 indicates the cam cylinder of any usual and well knownr construction to which my improvenient is applied. the inner wall of said cylinder are secured the raised stitch. cams 6 find 7 having the bevel-return ends 8 and 9 respectively which with the inclined edges 10 and 11 of the bottdmcenter cam 12 form channels 13 and 1 1 leadin to the inrlined edges 15 and 16 of the cams 17 and 18which form 75 part of the usual-cam ledge. The stitch cam lead or guide members 19 and 20are separate from and jit the uppe'r end portions of the stitch camt'fi and 7 and have the" clined lead or gu ide members 19 and 20 are mounted on thelliil'ideblock which is slidable radially relative to the cam cylinder in the guide box 26 formed in part with the wall edges 21, 22 and 23, 24;, respectively and said 27 of the cam cylinder 5, and on this block 25 is also mounted the top center cam 28 positioned at a point; intermediate the ends of stitch cam members 1'9 and 20 and extendin'g above said cam members 19 and 20.
Said block 25 is pressed inward by the spring has in its upper wall a slot through which extends pin 31 fixed at its inner end, to a member of the slide block 25 and having its outer end engaged by the thumb lever 82 pivl the stud secured in said otally mounted on guide box 26;
In the ordinary operation of the machine the butts of the needles will ride on the upper edges of the stitch cams 6 or 7, as the case may be, depending on the direction of relative rotary movement of the cam cylinthe direction of the top center cam 28 and, m
after leaving cam vmember 1'9 or wil1 be guided downward and will .thenpass through one of the channels 13 or 14 to one of the channels between said stitch cam 6 or 7 and its related cam member 17 or 18.
When, new, it is desired to avoid the operation of the needles, last above described, manualpressure is applied to the free end of lever 32 to move said lever in a direction .to slidably retract blockand the parts attached thereto from its normal position so that the stitch cam members 19, 20'and .the top center cam 28 are moved away, to
one side, of the path of the needle butts -at this portion of the cam cylinder so that said needle butts in their riding movement are free to pass along the Whole length of the needle leveling upper edge of stitch cam 6 or 7, then'to the upper edge of the der is stationary or rotary but I prefer to make use of the same on a cam cylinder of the stationary type or construction and in combination with a rotary needle cylinder.
claim as new and desire to' secure by Letters Patent. i I
1. A cam cylinder for knitting machines comprising a cylindrical wall, a pair of stitch cams each consisting of upper and lower members of which the lower members are fixed to said wall and have upper needle leveling edges, a block slidably mounted to move radially between said fixed members ofsaid stitch cams, said upper stitch cam members fixed to said block and having their lower edges in slidable contact with the needle leveling edges of said lower stitch cam members, and a top center cam mounted on said block,
2. A cam cylinder for knitting machines comprising a cylindrical wall, a pair of needle leveling stitch cam members fixed thereto and spaced apart, abottom center v cam fixed to said Wall and having its upper edge in alinement with the needle leveling members of said stitch cams, a movable carrier above said bottom center cam, and a top center cam and a pair of stitch cam members mounted on said carrier, said latter pair of stitch cam members adapted in a position of said carrier to co'riperate withsaid fixed stitch cam members;
