Title: Improvements in clutch mechanism particularly applicable to wire twisting or tying machines
IPC: B65B13/28
Filed: 1923-05-26
Abstract: 221,834. Ingold, E. A. May 26, 1923. Clutches, claw; operating clutches.-In clutch mechanism for coupling a driving- wheel to a driven shaft, an axially-movable bolt is held from engagement with a cooperating member on the wheel by a latch until the latch is automatically withdrawn by means driven from the wheel, when upon manual actuation of a starting-handle, the bolt is moved by an axially-aligned sliding rod, the rear end of which is then automatically engaged by a catch. The device is described as applied to driving mechanism for twisting the ends of the wire in a box-tying machine, wherein the twisting-pinions are slightly reversed to free the wire at the end of the twist. The main shaft 4 drives in opposite directions the twisting-pinions 5, 6 and carries loosely a driving-wheel 1 provided with one or more inclined dog teeth 10 and a corresponding number of cams 12. A disc 3 fast on the shaft carries an axially-slidable bolt 9 normally held retracted by a pivoted spring-pulled latch 11 engaging a notch 14. At appropriate times, the cams 12 co-operate with a bowl 15 to raise the catch, when the bolt can be thrust into engagement by a spring-pressed rod 21 contacting with a roller 42. This rod is manually tripped by a handle (not shown) adapted to turn a lever 27, which frees a catch 22 from an adjustable stop 23, as shown in Fig. 1, the rod being held forward by an apertured spring catch 30. The rod 21 traverses a hole 17 in a disc 18, loose on the shaft 4 and capable of limited rotation determined by stops 19, 20, Fig. 5. Rotation of the shaft 4 resets the catch 30 by a cam 31, and the rod 21 by a cam 28, so freeing the disc 18, which is then turned in the same direction as the shaft until its arm 36 meets the stop 20. This motion is derived from the engagement with its ledge 35 of a pin 34 on a gear-driven shaft 33, Fig. 5, but according to the Provisional Specification, the disc is carried forward by friction. After the shaft 4 has made a fraction more than one revolution, the engaged tooth 10 thrusts the bolt 9 into the aperture 17, so uncoupling the wheel 1 and coupling the discs 3, 18. An independentlydriven cam shaft 8, controlled by a clutch 7 as described in Specification 202,335, actuates through a cam 37 and linkage 39a a lever 39 to restore the arm 36 to the stop 19, so reversing the shaft 4 and bringing the aperture 17 and rod 21 into alignment for a new cycle. The disc 18 is held in this position by the rod 21, which projects slightly into the aperture 17 except when withdrawn by the cam 28. One face of the disc has a tapered recess 41 to lead the roller 42 into the aperture, and the other face a recess 40 to prevent deformation of the pin 34 by hammering of the rod 21 on the edge of the aperture.

Filed: 1921-05-21
Abstract: 164,016. Wirebounds Patents Co., (Assignees of Thompson, O. C.). June 2, 1920, [Convention date]. Shearing; shear - blades. - A machine for making wire-bound boxes, crates, and the like has a special shearing mechanism for the binding wires that is rendered operative at the desired times by controlling members adjustably mounted on the work-conveying mechanism. Cleats and side material are located by spacers 4 on a conveyer 3 fed step by step by a ratchet wheel 8 operated by an eccentric 12 in timed relation to the reciprocation of the actuating bar 19 and eccentrics 21 of the staple-driving mechanism and to the operation of the wire-feed mechanism 17 of the staple-forming device by the eccentric 22. The cams 47 are adjustably mounted on spacers 4 and so arranged that they actuate the shearing devices so that wire ends of the requisite length for forming fastenings are left on the separated box blanks. The shearing devices are adjustably mounted on the cross-rail 18 of the stapling mechanism and are actuated by arms 30 pivoted to members carried by the bar 19 and normally held towards the left in Fig. 3 by springs 39. When a cam 47 engages a lever 49 a bar 44 carrying fingers 42 is moved to the right in Fig. 2 against the action of controlling springs, and the ringers 42 enter the casings of the shearing devices and deflect the arms 30 to the right, causing notches 40 to engage latches 41 carried by slides on which the lower cutters 32 are pivotally mounted. These cutters, normally maintained inoperative above the wires, are then carried down and their bevelled lower ends cause them to snap under the wires under the control of springs 36. On the upstroke of the arms 30, the wires are severed against the fixed cutters 31 and cams 53 engage shoulders 52 and trip the notches 40 from engagement with the latches 41. The arms 30 then reciprocate idly until a further cam 47 comes into operation. The shearing devices are so placed in relation to the staple driving mechanism that at least one staple is driven across each of the wires of the rear box blank before the severing occurs. Various means for controlling, varying, adjusting, and braking the feed mechanism may be provided.

Filed: 1957-05-06
Abstract: 846,131. Semi-conductor radio receiving circuits. TEXAS INSTRUMENTS Inc. May 6, 1957 [May 15, 1956], No. 14362/57. Class 40(6). The radio-frequency input stage of a transistor receiver comprises a parallel-tuned circuit, part, at least, of which is connected in parallel with a semiconductor diode so that when large-amplitude signals are received, the resistance of the diode falls to increase the damping of the tuned circuit and reduce overloading of the first stage of the receiver. In the arrangement shown, the diode 19 is connected in series with variable resistor 20 and emitter-bias resistor 17 across the tuned circuit 12, 13, 14. The diode is so poled that in addition to increasing the load on the circuit for large-amplitude signals it produces a positive bias to reduce the gain of the transistor 16. The shunting effect of the diode may be adjusted to a desired value -by variation of the resistor 20. The diode 19 may be composed of any suitable semi-conductor material; some advantage may be gained by the use of silicon diodes which do not become effective until voltage input levels which are higher than those required for germanium diodes are reached. In modified forms of circuit, Figs. 2 and 3 -(not shown), the diode exercises a shunting effect only and does not provide a bias for the emitter of the transistor. In a further modification, Fig. 4 (not shown) a double-base grown-junction type transistor is used.

Abstract: 611,891. Making cartridge cases. IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 13, 1946, No. 14388. Convention date, Nov. 10, 1944. [Classes 83 (ii) and 83 (iv)] Cupping-dies; altering physical structure.- A method of making a cartridge case comprises shaping a metal blank into a hollow elongated piece of the general cylindrical form and size of the finished case, hardening a limited portion by an abrupt cold working and then cold working the case to complete the shaping thereof. A disc is punched out from a metal strip and pressed into cup form. The cup is drawn through a plurality of dies and the closed end is shaped to form the blank shown at 1 in Fig. 4. The invention is applicable particularly to making a .50 calibre cartridge case from a steel blank which has been quench hardened but may or may not have been annealed. The blank 1 of Fig. 4 is subjected to an abrupt work hardening in a region from the mouth to a point p, as shown at 2, slightly below the shoulder s of the finished case. This involves a reduction in diameter of the mouth portion of substantially 0.104 inches by driving over it a die holder 10, containing a top spacer block 11, a taper die 12 having an included angle of 14‹ 30<SP>1</SP>, a guide 13 and a bottom spacer block 14. The metal which is abruptly worked by the die 12 is strained beyond the yield point elongation of the material and this reduces the tendency of the metal to fold on subsequent tapering. A tapering operation is then carried out by known means to form the blank 3 which is subsequently formed with a neck f and shoulder s, as shown at 4.

A corrugated nozzle for reducing the noise of jet propulsion engines comprises a tubular structure of generally circular cross-section with a series of circumferentially spaced V- shaped corrugations having the apex of the V nearer the axis of the nozzle and having plane walls which are inclined to each other in both the radial and axial directions so that each pair of corrugations defines between them a channel which deepens and narrows progressively from the upstream to the downstream end. As shown, the tubular structure 10 has six equally spaced corrugations 14 with side walls 18 defining between them channels 16 of substantially rectangular section which becoming progressively wider and shallower towards the inlet where they merge with the tubular structure 10. The radial dimension of each channel is greater than the circumferential dimension and may be 0.25 of the maximum diameter of the nozzle. The corrugations are reinforced by axially spaced arched stiffeners 19, 20, the most downstream of which 20 is set back from the apex of the corrugation. The corrugations form flutes in the external wall of the tubular structure 10 through which flutes cooling air flows to penetrate furthest into the jet stream. The tubular structure 10 is reinforced by hoops 13 and rings 11, 12. A hinged trimmer flap 30 is pivoted in one of the channels 16 between the walls 18. The flap is hinged to the tubular structure and carries a vane 33 displaceable in a balance chamber 31 by air under pressure conveniently tapped from the engine compressor delivery and supplied by a pipe 35. The flap is movable to and from an operative position in which it obstructs the gas flow in the channel.
