KNlTTlNGu-MAcHlNE a nmssaeeo.

, citizenof the United States; residing at Ger- .mantown, in the county. of Philadelphia. and

State of Pennsylvania, have invented certain new. and useful Im rovements in Kn tting- Maehines; and I do ereby declare the following to be a full, clear, and exact description of the invention, such as will enable others Skilled in the art to which it appertains to 1 1 make and use the same.

' hiypresent invention relates to knitting [machines for producing ribbed work and g plated embodying my said invention and the i I "j jvhich employ two sets of needles, one set working vertically and the other horizontally, andmore particularly to such of said ,machines as are constructed to produce welts 1 I for the tops of half hose and like articles.

In the accompanying drawings, I have illustrated one'form in which I have contemsame is disclosed in the following description and claims.

In the said drawings, Figure -1 is a side elevation of a machine of the class specified in which are embodied my improvements.

cam cylinder C. This cam cylinder is romachine is secured the bracket I) in which is mounted the gudgeon 11. Upon this gudgcon are mounted the cams e e and the ratchet c'. A pawl f engages the ratchet with which it is kept in contact by springj". The pawl f is ivoted to a rod or barf which is normally held in an elevated position by a spring. The upper end of the rodj' engages the cam c and 18 by this cam depressed once each revolution of the cam cylinder advancing the ratchet one tooth and as the cams e and e are secured to the ratchet for joint movement .these devices are also moved forward with it.

The ratchet is a mutilated ratchet having at e one tooth removed. When the ratchet has been turned to the point at which the. pawl falls upon the'mutilated portion the ratchet and the cams e e come to a state of rest. Upon the gudgeon (Z is also movably mounted the web friction wheel G having a' card cloth surface by means of which web in passing over the same imparts motion to the wheel G. The web friction wheel Ghas secured thereto a chain wheel G upon which is mounted the pattern chain 9 carrying the pins or projections g extending toward the ratchet wheel 6. with the pin e extending toward t e chain and chain wheel in the path of the pins g.

The construction is such thatwhen the' ratchet is at rest, if motion is given to the friction wheel the chain g will be moved until one of the pins g comes in contact with the projection e on the ratchet and moves the said ratchet forward far enough to en- The ratchet e is rovided Outside of the needle cyhnder is the usual To the underside of the bed;plate of the able the pawl to engage the next ratchet tooth when the pawl will again actuate the ratchet and the cams e e.

The cams e e control the operation of the dial needles and the length of the stitch made by the cylinder needles. To eil'ect a change in the stitch the cylinder knittingcam is movably mounted, by being secured to a block 0 setin a slot in the wall of the cylinder. This Block has a portion extendmow of. the flange and the tension is again put .lliillthislcanl pla'tc'isd'lmdO fast by set screws {,nintilrc. movement of the-dial cam plate in ,un sonf ,wrththe cam cylinder 18 secured. 5.

The dial needle plate L having radial needle grooves, is movably mounted on the rod ,or shal't K-and is secured in position by the "collarl fixed-to said rod or shaft. To the hub of the dial needle plate L is secured a collar M liavin'gtwo depending arms m m each of l which bears against'a roller a secured to the underside of the bed plate of the machine in such osition that the. dial needle plate will be he (I from any forward movement while the knitted web will be permitted to pass downward between the arms m and the rollers -n.

The cam disk e controls the dial late needles, throwingtheminto and out action in a well known way, such needles, as is well understood, being at rest during the making of "the \velt, while the disk e controls the knitting cam increasing' the length of stitch durmg the formation of the welt;

having been placed between the gripping rollers .duringthe knitting ol the ribbed body of the fahric,the pawlj rests on the mutilated part of the ratchet e and the said ratchet. and the cams e 0' remain stationary. -The web passing over the web friction roller G ,under the strain of the ten sion device the said roller is moved forward wlth the eham wheel until one of the pins 9 comes; in contact- Wltlt the pin e on the ratchet and 1110\i85 the ratchet forward until the pawl f engsl es the teeth of thesame. The ratchet is en advanced bringing the (ram 1' under the lirojection h on rod h" lifting the rod and. relcfasing the web from tension.

This movement;- of the ratchet and cams throws the "dial needles out of action and depresses theknitting cam to lengthen the stitch. The welt is then knit. the pawl act- =ing ontheratchet- When the welt is completed the cams e and e are brought into position and throw the dial needles a ain into 'operation'and shorten the stitch to t e length desiredfor ribbcdwork at the same time the projection it drops from the concentric face upon the web. u'lhe ratchet iskept in mo- "tlon' until the pawl f again reaches the mutilat-ed. portion when the movement of the ratchet and cams is stopped leaving the cams -nd other partsin proper position to begin another welt.

- When knitting the welt as has been shown, the web is released from tension and to secure the-casting oil of the stitches and the holdin down of the nl'k, I provide the rigid hool i web-holders b. I'lhe construction is cheaper.
