Description
Inventor fl Zfihcm Zeubn Gttomcgs Patented Sept. 5, 1933 PATENT OFFICE DESIGN WHEEL Nathan Levin, Trenton, N. J., assignor to H. v Brinton Company, Philadelphia, Pa., a corporation of Pennsylvania Application August 1, 1931. Serial No. 554,565
Claims.
My invention relates to a design wheel and it is an object thereof to provide a wheel of this character with inserts that can readily be removed and replaced, all without dismantling the '5 wheel as has heretofore been necessary in case of breakage or injury to an insert.
Referring to the drawing, which is made a part of this application and in which similar reference characters indicate similar parts:
Fig. 1 is a plan of my improved wheel showing a number of inserts in place.
Fig. 2, a partial section on line 2-2 of Fig. 1, Fig. 3, a fragmentary elevation of the wheel, 4, a perspectiveof one form of insert that may be used, and
Fig. 5, a similar view of another form.
In the drawing reference character indicates 1e body of the wheel which is provided with radial slots 11, these slots being inclined with re- 2 spect to the axis of the wheel in the case of wheels which are mounted on an axis inclined to the perpendicular as in the familiar case of a design wheel used for selectively elevating needles in an independent needle knitting machine. A cireumferential groove is indicated at 12 in the periphery of the wheel, this groove'intersecting the slots 11. In a preferred construction the upper part of the body is cut back so that the radially extending portions 13 above the groove 12 are shorter than the radially extending portions 1 1 below said groove, this facilitating the operation of as-- sembling the parts.
In the preferred construction the slots 11 are closed at one side of the wheel-here shown as the underside-by means of a plate 15 secured to the body of the wheel by screws 16' or in any other convenient manner, though it is to be understood that the parts 10 and 15 could be integral if desired.
0 Each of the slots 11 is adapted to receive an insert such as shown at 16 and 1'7, said inserts resting on the smooth upper face of plate 15 and the specific inserts being merely for purposes of illustration since obviously inserts of other types could be used in the wheel. In the present em bodiment of the invention these inserts are of a type suitable for lifting needles selectively in an independent needle machine. Each of the inserts has an upwardly extending arm 18 adapted O to be positioned behind a spring ring shown at 19 in the groove 12 and it will be evident that the inserts may be positioned in the wheel by merely turning them so as to enable the arm 18 to be inserted first below and then at the rear of the spring ring, which ring will yield sufficiently to enable the insert to be properly positioned. The reverse movement serves for'removal of an insert from the wheel and this makes it very easy to replace an insert when the same is damaged or broken, or when a different pattern is '60 desired or the like. At their rear or inner ends the inserts are preferably rounded off to facilitate removal or replacement.
In the embodiment of the invention here illustrated the. inserts 16 are each provided with a '6 laterally extending ledge 20 which is of such a width as to close the space between two successive inserts and thus be well adapted for lifting needles selectively. The inserts 1'7 do not have this ledge but also extend out beyond the periphery of the wheel so as to engage the needles and drive the wheel in the well known manner of driving a design wheel by engagement with the needles.
It will be obvious to those skilled in the art that many variations may be made in my device and that it may be used in general for any of the purposes for which design wheels are used in knitting machines, all without departing from the spirit of the invention, therefore I do not limit myself to what is shown in the drawing or described in the specification but only as indicated in the appended claims.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
1. A design wheel having radial slots in its periphery said slots being inclined relatively to the axisof the wheel and closed at one side of the wheel, a circumferential groove in the periphery of the wheel intersecting the radial slots, a coiled spring ring in the circumferential groove, and inserts in the radial slots each having an angularly related arm extending upward behind said ring 2. A design wheel comprising a body having radial slots in its outer portions said slots being inclined to the axis of the wheel, said wheel also having a circumferential groove in its periphery intersecting the radial slots, a spring ring in the circumferential groove, a plate secured to the' under side of the wheel, said plate having a smooth upper face, and inserts in said slots lying on said upper face of the plate said inserts having their under faces rounded off at the inner end and, having arms lying behind said spring ring.
3. In a design wheel, an insert having a fiat body, an angularly related arm in the plane of the body at its inner end, the under side of said 5. A design wheel having radial slots in its periphery said slots being closed at one side of the wheel, a circumferential groove intersecting the radial slots, a ring in the circumferential groove, and angular inserts in the radial slots each having an arm extending behind said ring, said inserts being rounded ofi at their inner ends.
