Title: Improvements in or relating to knitting machines
IPC: D04B9/26
Filed: 1934-03-15
Abstract: 435,122. Knitting. BOOTON, Ltd., W. E., and BOOTON, W. E., Wanlip Street, Leicester. March 15, 1934, No. 8215. [Class 74 (ii)] Patterning mechanism of the kind comprising two beds carrying, respectively, actuating and co-operating instruments, capable of mutually transverse movement, each instrument in one bed being associated with one, or a small group in the other bed, and having co-operating wedge surfaces so that movement of an actuating instrument impels its co-operating instrument in a direction transverse to this movement, is characterized by further co-operating surfaces on the associated instruments, disposed obliquely to the first surfaces, and, through which, means operating on the instruments of one bed can effect movement of instruments of the other bed. Noses 23 on bits 14 co-operate with the oblique edges of notches 13 formed in the jacks 11, operating the plating spears of Specifications 406,657, and 430,498. A pattern device such as a drum 29, advances certain of the bits 14, through selecting levers 40, and butts 22, so that the upper edges of nose 23 and notch 13 engage, to raise the jack (Figs. 3A and 3B) until a butt 26 thereon is brought into the track of a dividing cam 27, which raises it still further. This, after some lost motion, due to the shape of the notch, causes the lower edges of notch and nose to contact, thus retracting the bit, which may be advanced again by a deselecting drum 129 to lower the jack, until a downthrow cam 28, engages the butt 26, to complete the lowering of the jack, and, by interengagement of the upper edges of nose and notch, finally to retract the bit. A rod 45, interconnects the racking mechanism of the drums, both of which may be rendered inoperative together by lifting the followers 37, 137, operating the clawkers 34, 134, from the cam 38. Bluffing rods 50, 150, are adapted to mask some teeth on the ratchet wheels 33, 133, at the end of a patterned area, until patterning is to commence on the next half hose. Circumferential adjustment of both drums is possible, by means of an arcuate groove 56.

Title: Improvements connected with controlling means for electric hoisting motors
IPC: B66C13/54
Filed: 1945-04-05
Abstract: 589,946. Correspondence control systems. ATOSSAY, P. A. H. April 5, 1945, No. 8474. [Class 40 (i)] [Also in Group XXXVII] In follow-up system for moving a regulator for an electric motor to a position corresponding to that of a. manual controller and including a pilot motor driving the regulator, a controller in two parts, one of which is driven by the pilot motor, and a handle which can move the two parts of the controller relatively to each other to set the pilot motor in motion, the handle can also be moved relatively to the two parts of the controller to control the circuit for switching the main motor on and off. The handle may be movable in two different planes. In Fig. 1 the casing 6, enclosing the controller, can be turned by handle 15 about the shaft 4 driven by the regulator. Depression of knob 18 against the spring 17 engages the locking bolt 16 in a hole in the plunger 13. Movement of the handle 15 about pivot 21 then moves plunger 16-against one of the springs 14 and 14<1>-until contact 11 engages fixed contacts to control the starting of the main motor. The same movement raises or lowers the ward 27 so that it can enter guideway 23 or 24 in a fixed stop ; this allows the handle and casing to turn about shaft 4, until contacts 30 and 31 engage the contact 32 carried by the arm 33 secured to the shaft 4, thereby starting the pilot motor (not shown), which drives the regulator and the shaft 4 until the contact 32 separates from contacts 30 and 31. Release of the knob 18 frees the plunger 13 and switches off the main motor ; the bolt 16 cannot be re-engaged with plunger 13 until the casing has been returned to its " off " position and the handle 15 turned about pivot 21, back to its mid-position in which it is located by spring catch 19. When the casing is turned back towards' the "off" position, contacts 28 and 29 engage the contact 32 to start the pilot motor for driving the regulator in the reverse direction. The motion of the casing is limited by the dog 37 thereon moving in a fixed slot 37a. Limit switches limit the motion of the regulator.
