Abstract: 489,679. Knitting-machines. LIEBERKNECHT, R., and LIEBERKNECHT, K., (trading as LIEBERKNECHT, K., [Firm of]). April 28, 1937, No. 12129. Convention date, April 29, 1936. [Class 74 (ii)] Knitted fabric embodying stitch-locking loops is produced on a straight-bar machine having auxiliary needles which are rocked and moved longitudinally of the frame needles to engage the locking loops. As shown in Figs. 1 and 6 auxiliary needles 4 bent to knee shape to bear against the frame needles 1 are mounted on a bar 6 closely behind the knocking-over bits 7, each auxiliary needle terminating in a hook 4a and being provided with a groove at the knee for guiding the needle positively on the corresponding frame needle. When locked stitches are to be produced, the knitted loops are passed over the auxiliary needles 4 to knee level and locking loops 3 are sunk on the frame needles as shown in Fig. 1, whereupon the needles 4 are rocked anticlockwise about the point 5 and raised to bring the hooks 4a above the loops 3. The needles 4 are then rocked clockwise and lowered to pull the loops 3, Fig. 3, through the knitted loops 8 which are cast off on to the frame needles. During the subsequent downward movement of the needles, the knitted loops 8 pass into the hooks of the frame needles and the loops 3 released by the needles 4 to be cast off over the heads of the needles 1. To render possible the rocking movement of the needles 4, needle bar supporting arms are mounted on pivots 5a, Fig. 6, on arms 18 and the rocking movement is imparted by a rod 31 and cam operated levers 30, 26. The auxiliary needle bar 6 is also movable vertically and horizontally by cam operated levers 12, 19 connected to the levers 18 through shafts 10 and 17. Specification 412,524 is referred to.

IPC: B65H67/06
Filed: 1953-05-04
Abstract: 726,605. Collecting bobbins from textilespinning &c., machines. WHITIN MACHINE WORKS. May 4, 1953, No. 12353/53. Class 120 (3).  Pin-board loading mechanism for a bobbinwinding machine comprises a continuouslymoving conveyer having buckets to receive and transport full bobbins, a second conveyer having bobbin-holding carrier units, means to advance the second conveyer step-by-step, and a single moving transfer member for transferring automatically a full bobbin from a bucket on the first conveyer direct to a carrier unit on the second conveyer : a supply of pinboards from a stack may be automatically maintained. In the operation of the apparatus shown and starting from the position shown in Fig. 2, as a filled bucket 22, Fig. 6, reaches the discharge position at the end of a conveyer C, a pin 24 which is depressed by the weight of a bobbin B closes a switch S to energise electromagnetic means whereby a wedge 29 is withdrawn to permit a latch 30 to engage a clutch disc 31 and cause a shaft 35 and a shaft 50 geared thereto to make one revolution : a cam disc 54 operates through a slide 48 to swing a member 40 upwardly and so transfer a wound bobbin received therein from the bucket 22 to a position B<SP>1</SP> in one of a number of carrier units 60 in a conveyer C<SP>1</SP> which is then advanced one step by a Geneva pinion 65 and gear 66, Fig. 7. Chains 90 and 91 supporting a pin-board D also receive an intermittent advance movement from the shaft 35 driving through a pawl 98 and ratchet wheel 100, the board being held against such advance by the engagement of end pins P<SP>1</SP> with star wheels 102 which are held from rotation by latches 103, Fig. 8. After eight successive advance movements of the carrier C<SP>1</SP> an arm 74 is released from a disc 67 through a notch 72 to actuate withdrawal of a cross-bar 70 so that a row of bobbins B<SP>1</SP> in the units 60 drop on a row of pins P : latches 103 are momentarily released by the backward movement of the bar 70 and the board D is freed to be advanced one step to a position for receiving another row of bobbins. When the pin-board D is filled, its next forward movement frees a lever 110 to close a switch 52 so energising electro-magnetic means enabling a shaft 116 to make one complete revolution during which an eccentric 125, Fig. 9, operates initially through a lever 127 to lift a plunger 130, a plate 131, and hence a stack of empty pin-boards D<SP>1</SP> sufficiently to release weighted catches 122, and then, on the subsequent downward movement of the stack, the lowermost pin-board is desposited on the chains 90 and 91 and the next board in the stack is caught and supported by the latches 122. The deposited board is then advanced into position to receive bobbins dropping from the units 60.
