KNITTING-FRAME.

Specification of Letters Patent. Patented Apr. 25, ll llfiw Application filed January 14, 1915. Serial No. 2,174.

To all whom it may concern:

Be it known that I, FRANZ CEGKA, a citizen of the German Empire, residing at Chemnitz, in the Kingdom of Saxony, Germany, have invented certain new and useful Improvements in Knitting-Frames; and I do hereby 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 make and use the same, reference being had'to the accompanying drawings, and to letters or fig ures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in knitting frames, and more particularly in apparatus for knitting in hosiery or the like patterns from reinforcing threads, and the object of the improvements is to provide an apparatus of this class, by means of which reinforced portions can be knitted in the medial parts of the fabric as distinguished from. known frames by means of which reinforced portions can be knitted only at the side's of the fabric. Thereby ll am enabled to produce patterns of various form, and the effect of such reinforced portions can be increased by knitting the same from threads of a color different from that of the foundation.

For the purpose of explaining the invention an example embodying the same has been shown in the. accompanying drawings, in which the same letters of reference have been used in all the views to indicate corresponding parts.

In said drawings-Figure 1, is a front view of the parts of the knitting frame to which my invention more particularly relates, Fig. 2, is a detail view showing one of the thread guides in a different position, and Figs. 3 to 8, are respectively side views and plan views of the driving elements of the improved apparatus and showing the same in difi'erent positions.

For the purpose of explaining the invention reference will be made to a flat hosiery frame of lmown construction. But I wish it to be understood, that my invention is not limited to the construction shown in the drawings, nor to the use in combination with a flat hosiery frame.

Referring now to the drawings, a rod 1 is connected in the usual way with a slur connecting bar (not shown) so as to take part in the reclprocating movements of the same. Therod is adapted to impart reciprocatlng movement to rails 2 and 3 which carry additional thread guides 4 and 5 which are used in knitting reinforcing threads. The rod 1 carries thread guide brakes 6 and 7 the arms of which are arranged for engagement in carrying members 8 and 9 provided on the rails 2 and 3. The carrying member'9 is formed with two notches 9' and 9" which are adapted to be engaged'by the arm of the brake 7.

To a shaft 10 a pinion 11 issecured which is connected with ratchet wheels 12 and 13 having their teeth disposed in opposite directions, and which is engaged on opposite sides by racks 14 and 15 formed with reduced portions 16 and 17 providing shoulders 16, 16 and 17, 17". The rod 1 on which the thread guide brakes 6 and 7 are mounted is located between the rails 14 and 15. The brake 6 extends between the shoulders l6 and 16 of the rack 14 and the brake 7 between the shoulders 17" and 17 of the rack 15. The end of the rack 14 is located in the path of the brake 7 and the end of .the rack 15 in the path of the brake 6.

At 18 and 19 levers 20 and 21 have rocking supports. The lever 20 carries a pawl 22 which is adapted to act on the ratchet wheel 12, and it has an arm 23 linked thereto which is connected with a pawl 25 mounted at 24 and acting on the ratchet wheel 13. The lever 21 carries a pawl 26 which acts on the ratchet wheel 13, and it has an arm 27 linked thereto which is connected with a pawl 29 supported at 28 and acting on the ratchet wheel 12. Further more to the lever 20 a link 30 is jointed and to the lever 21 a link 31. The links 30 and 31 are connected by a bail 32. The latter is made integral with an arm 33 which is connected by a bell crank lever 34 with a rod 35 connected with a counting mechanism, a

Jacquard pattern, or the like.

On a bracket 36 a.lever 37 is mounted which carries a rotary disk 38. The free end of the said lever carries a transverse arm 43, the end parts 39 and 40 of which extend into the paths of the links 30 and 31. To a shaft 41 and in position for engagement with the disk 38 a cam 42 is secured.

The operation of the apparatus is as fol- When the cam 42 secured to the shaft 41 is lowsz'As appears from Figs. 3 to 8, the bail 32 has such a form, that the links 30 and 31 are staggered with relation to each other.

4 counting mechanism in either one of the positions shown in Figs. 4 and 7, the link 31 gets in position above the end part 40 of the transverse arm 43 connected with the lever 37, so that when the lever 37 .is rocked upward the link 31 is lifted, so that the lever 21 is rocked and the pawl 26 advances the ratchet wheel 13. Thereby the racks 14 and 15 which are in engagement with the pinion 11 are shifted respectively to the right and to the left. When the bail 32 and the links 30 and 31 are set in the positions shown'in Figs. 5 and 8, the link 31 getsout of the path of the end part 40 of the arm 43 and the link 30 gets in position above the end part 39 and causes the pawl 22 to act on the ratchet wheel 12.- Thereby the rods 14 and 15 are moved in the opposite direction.

positions in which the brake 6 is engaged by the shoulder 16 of'the reduced portion 16 of the rack 14 and by the end of the rack 15. In the same way the brake 7 is held in position by the shoulder 17' of the rack 15 and the end of the rack 14. Therefore the thread guides 4 and 5 can not move. If it is desired to knit reinforced patterns,- the rod 14 is shifted to the left by the ratchet mechanism, so that the brakes are released and can move so as to be able to move together with the rod 1. According to the path through which the brakes can move also the additional thread guides 4 and 5 can move. The path of the latter can be increased to the length of the reduced portions 16 and 17. By properly operating the ratchet mechanism and thereby increasing or decreasing the path patterns of different form can be produced.

In order that instead of a pattern which is repeated-on the fabric a central pattern can be produced the second notch 9 of the carrier 9 is provided. When the arm of the thread guide brake 7 is' thrown into engagement with the notch 9", the thread guide 5 gets in a medial position, as is shown in Fig. 2, and the thread guide 4 must'be'thrown out of: operation'.' For limiting thepaths of the brakes 6 and 7 special arm sor the like may be secured to-the rods 14 and 15; which can be made soas to be set in difl' 'erent positions for chan'gihg' the path of the brake Preferably the upper ends of the parts 39 In Fig. 1 I have shown the parts in the 1. In a knitting frame, the combinationwith the main knitting mechanism, of at least one additional thread guide, operating means therefor yieldingly connected therewith, a pair of parallel racks adapted to stop the thread guide, a pinion engaging said racks for movement thereof in opposite directions, a pair of pawls and ratchet wheels connected with the pinion for rotation of the same in opposite directions, shiftable links carrying each one of the pawls, a rocker adapted to shift the links, operating means for the rocker, and operating means for the pawls.

2. In a knitting frame, the combination with the main knitting mechanism, of at least one additional thread guide, operating means therefor yieldingly connected therewith, a pair of parallel racks adapted to stop the thread guide, a pinion engaging said racks for movement thereof in opposite directions, a pair of pawls and ratchet wheels connected with the pinion for rotation of the same in opposite directions, shiftable links carrying each one of the pawls, a rocker adapted to shift the links,'operating means for the rocker, means to set the links in positions for operation by the rocker, and

operating means for the pawls.

3. In a knitting frame, the combination with the main knitting mechanism, of at least one additional thread guide, operating means therefor yieldingly connected therewith, a pair of parallel racks adapted to stop the thread guide, a pinion engagin said racks for movement thereofin opposlte directions, a pair of pawls and ratchet wheels connected with the pinion for rotation of stop the thread guide, a pinion engaging said racks for movement thereof in opposite directions, a pair of pawls and ratchet wheels connected withthe pinion for rotation of the same 1n opposlte directions, shiftable links carrying each one of the pawls, a rocker adapted to shift the links, operating means for the rocker, means to set either one of the links inpositions for operation by the rocker, and operating means for the pawls.

5. In a knitting frame, the combination with the main knitting mechanism, of two additional thread guides, means for imparting a reciprocating motion to said guides, a carrying member for at least one of the said additional thread guides, an adjustable connection between said reciprocating means and said carrier adapted to change the position of said carrier relatively to said re- 10 ciprocating means, and automatic means for varying the stroke of the additional thread guides at both ends of the stroke.

In testimony that I claim the foregoing as my invention, 1 have signed my name in presence of two subscribing witnesses.
