KQBERV von! SKEr/e, kluy WERNER LEHKEIT N10 LISBETH ALIBDK BY wlw Referring now to the drawings, a needle board 2 is mounted on a supporting means l and is secured thereto by bolts and nuts 5. The bolt 5 passes through transversal slots 6 inthe needle board 2 so that the same may be adjusted transversely on the supporting means I. A stationary needle comb 'f' constituting a retaining means is mounted on the supporting means I, and the distance between the supporting means and the needle board 2, on one hand, and the needle comb I on the other hand may-be gradually adjusted by lever means 8.

A longitudinally movable actuating member 3 is guided by rails l and provided with an eccentric groove 3 inwhich the projecting portions I0' pi the horizontal needles IG are guided. The .walls of the groove 3 constitute cam means for consecutively moving the needles I0 in a trans- 'versal direction' when the movable actuating member 3 is longitudinally moved. The horizon- `tal needles it indicated in inactive position by reference numeral I2 are movable independently of each other from a retracted position indilcatedby the reference numeral II to an advanced position, and each horizontal needle ill passes during such movement between two adjacent vertical needles of the needle comb 'I'. The horizontal needles have hooked ends which are closed by pivoted tongues IG". The movable actuating member 3 is provided with an arm I4 on which a retaining means I4 is mounted. The retaining means I4 is provided ,with an operating face which is located below the plane defined by the row of horizontal needles and extends intermediate the needle comb 'I and the line dened by the hooked ends of the horizontal needles I0 in advanced position. Thread inserting means 9 are mounted on the arm I4 so the new thread is pulled therethrough and a new loop is formed. rihis new loop passes through the hooked endof the horizontal needle in retracted position behind the needle comb while the knitted piece is suspended thereon in front of the needle comb. Thereupon, the operation is repeated.

as to move with the movable actuating means hooks of the needles II! in retracted position II thereof. Since in the retracted position II of the horizontal needles the hooked ends thereof are located closely behind the needle comb i, the knitted piece hangs in front of the needle comb 'I. When the horizontal needles are consecutively advanced by the movable actuating means 3, each loop is carried' towards the thread inserting means 9, and whilethe hooked end is passing over the retaining means I4, the knitted piece is retained by the retaining means I4 whereby the loop is pulled out of the hooked end of the advancing needle so as to slide onto the shaft thereof. Consequently, the advancing needle arrives at kits most advanced position underthe thread inserting means free of a loop, and in this position a new thread is inserted into the hooked end thereof.

Further movement of the movable actuating means causes retraction of the needles, and when the hooked end of a retracted needle passes through the needle comb 7, the old loop by which the knitted piece is suspended from the shaft 'of the needle is retained by the vertical needles of the needle comb so that it passes over the hooked end of the horizontal needle whereby The hooked ends of the horizontal needles are provided with pivoted tongues IG which are opened by the old loops when the same are pulled out of the hooked .ends by the retaining means I4, and are closed again when the old loop on the shaft of the needle is pulled over the hooked end when a new loop is formed and the old loop is retained by the needle comb.

By adjusting the relative position of the needle comb with respect to the line dened by the horizontal-needles in retracted position, the size of the newly formed loops may be varied. Such adjustment may be carried out by transversely adjusting the needle comb 1, or the needle board 2.

It will be understood that each of the elements described above, or two or more together, may also ind a useful application in other types of hand knitting apparatus diiiering from the types described above.

While the invention has been illustrated and described as embodied in a hand knitting appaiatus having an adjustable vertically arranged needle comb and a set of horizontally movable needles, it is not intended to be limited to the details shown, since various modications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specic aspects of this invention and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
