GENERAL REPORT OF THE JUDGES OF GROUP XXII. 57 be made to knit a tubular web by revolving the cam-cylinder contin uously, or the cam-cylinder could be reciprocated part of a revolution backward or forward, for flat or other usual work. The lower edge of the stitch-cam, instead of being made V-shaped or horizontal as usual, was upwardly curved between its extreme ends, to permit one or two needles next back of the lower extreme forward or working end of the stitch-cam to rise, when a needle in the act of drawing a new through an old loop met a knot. This provision allowed the new loop to be partially formed from the thread held by the needles so permitted to rise, which thereby prevented the thread from being broken. The lower end of the stitch-cam was broad enough to hold down four needles, which was considered advantageous as compared with a V-cam, in the more even formation of loops, for the needles last drawn down were then less liable to shorten the loops of the adjacent needles, or “ rob” them of their share of thread. The thread-carrier, connected with the cam-cylinder so as to change its position at each change of direction of movement of the cylinder, to place the carrier in advance of the stitch-cam, was fitted into a slotted plate at the upper portion of the cylinder, and was stopped just before the cylinder completed its movement, by striking against the butt of a needle drawn up and held in the path of the thread-carrier shifter. This machine was very simple in construction and capable of pro ducing a good variety of work, and was sold at a lower price than any other circular machine exhibited. C. R. Tuttle Circular Knitting-Machine, New Brighton, Pa. This machine contained a circular series of vertically reciprocating latched needles operated by cams on the interior of a cam-cylinder. The cam-cylinder could be rotated continuously, or in opposite direc tions as usual, to knit flat-work or gores for heels and toes. To knit ribbed-work on this machine, a conical needle-bed grooved to receive ribbing needles was swung into position within the circle of vertical needles, and a projection on the conical bed then engaged a recess or lug at the interior of the vertical needle-bed, so that the movement of the latter carried with it the bed for the ribbing needles. For' plain knitting, the cam-cylinder or the vertical needle-bed could be rotated while the other remained at rest. When ribbed-work was being knit, it was necessary to rotate the bed. For such work every third needle was drawn up out of the main cylinder and turned and inserted into a groove in the conical bed, and such needles so transferred with their loops to the conical bed served as ribbing needles. After the proper length of ribbed-
