CIRCULAR-KNITTING MACHINE.

Specification of Letters Patent.

Application filed October 7, 1812. Serial No. 724,376.

Patented Dee. 9,1913.

7 To all whom it may concern."

Be it known that l, FRANK B. WILDMAN, a citizen of the United States, residing at Norristown, Pennsylvania, have invented certhe point of knitting may be of very small diameter, while at the same time the cam box will be of suflicient diameter to rovide a satisfactory cam race'to operate-t e needles. I a

The invention consists in the features of construction and arrangement and combinetion of parts hereinafter described and pa ticularly defined by the appended claims.

The accompanying drawing represents a.

central vertical sectional view through a ma-' chine embodying the invention.

lln this drawing, 1 represents the needle cylinder, which is of tapered form, and

which extends a considerable distance above the cam box 2, which carries the cam pieces forming the cam race 3. The tapered cylinder is grooved toreceive the needles, as in ordinary practice, and the butts of these needles, as in ordinary practice, enter the cam race 3. The cams are arran d in cylindrical form, as shown, but owing to t e slight taper of the needle cylinder the needles, in their up anddown movement, traverse a path only slightly inclined to the interior of the cam cylinder so that in their up and down movement the butts of the needles maintain-engagement with the cam race. in o'rder to get the needle cylinder at the knitting point of the required small diameter, the said cylinder, as above stated, is extended a considerable distance above By .arrangin the cams in cylindrical form and by'emp oying a cylinder of elongated tapered form, the diameter of the parts at the needle cams may be considerable as compared with the diameter of the needle cylinder at the knitting point, andthe room thus provided will enable a satisfactory cam race to be formed, as shown, and the needles will project into the earn race a suflicient distance for proper they lie in a circle of much larger diameter,

making it possible to employ a cam cylinder of a considerable size.

I claim as my invention l. A knitting machine consisting of an elongated needle bed of conical form, with its taper upward and a cam box surrounding the, lower larger diameter portion of the taper cylinder, said cam box having its cams arranged in plain cylindrical form, the needles traversing a path but of parallel with the cam surface, and inclining toward the center of the plain cylinder, substantially as described.

2. A knitting machine consisting of an elongated needle bed of conical form with its taper upward, a cam box surrounding the lower larger diameter portion of the conical needle bed, and a loose ring surroundin the conical needle bed to hold the needles in the grooves thereof, substantially as described.

In testimony whereof, I a'liix my signature in presence of two witnesses.

l RANK B, WILDMAN.
