Title: Method and apparatus for winding wire and the like
Inventor: ANNETT JOHN FREDERICK
IPC: B21F3/04
Filed: 1958-06-24
Abstract: 926,614. Winding wire; traverse mechanism. AVO Ltd., W. H. ATTWOOD, P. H. SEWELL, and S. R. WILKINS. June 22, 1959 [June 24, 1958], No. 20273/58. Class 120 (2). [Also in Group XXXV] Relates to a system in which the deviation of the feed-angle of a wire to a bobbin is used to restore automatically the angle to a predetermined value. The wire is taken over guides on reciprocable carriage 6 driven by electric motor 2, the bobbin 4 being rotated by electric motor 1. A coil 12 is pivotally mounted on the carriage by an arm 10 having pads between which the wire is trained, and is disposed in an air gap of magnet 14 which is energized with A.C. The output of coil 12 is taken to phase-sensitive amplifier 18 for exciting field windings 19, 20, of generators 21, 22, the generator 21 being driven by the motor I whilst the generator 22 is driven at a constant speed. A field winding 24 of generator 22 is adjustably excited by generator 21, and the armature of motor 2 is supplied by the constant-speed generator so that any signal due to a change in the feed-angle of the wire varies the speed of the carriage about the value set by the generator 21 and the adjustment of slider 29. Limit switches 30, 31, are set in conformity with a desired winding-length, and are adapted to operate a relay 32 having phase-change contacts 33 and motor-reversing contacts 34. In this manner, the conditions of constant feed-angle are held for a reverse direction of traverse. A potentiometer 35 imposes a variable potential on coil 12 to provide an adjustable null point in accordance with a desired feed-angle. The coil may be adjusted by a cam during a winding operation to produce close layer winding or spaced winding of predetermined spacing. The correction of the feed-angle may be effected by varying the speed of the bobbin or the speeds of both the bobbin and the carriage.

Title: Improvements in and relating to fountain pens
IPC: B43K5/18
Filed: 1955-07-13
Abstract: 811,715. Reservoir pens. HENNEFER SCHREIBWAREN - FABRIK RAUCHLER & CO. G.m.b.H.. July 13, 1955 [July 14, 1954], No. 20323/55. Class 146(3) A fountain pen ink feed has a reservoirto-nib supply duct 17, 19 on its upper side, an overflow-chamber system 7a, 7b below, and a connecting duct 13 (to link the chamber system both with the outer air and with the reservoir) arranged on the upper side of the chambers. As applied to a twopart hard-rubber ink feed wherein the part 3 above the nib 4 has two longitudinal capillary grooves 17 to lead ink from the reservoir to a crescent-shaped slot 19 at its nib end, and the lower part 2, recessed to receive the nib, is impressed &c. with chambers 7a, 7b decreasing in width on either side of the web 9 abutted by the nib, the duct 13 consists of notches, Fig. 3, cut alternately on opposite sides of the tops of the webs 8, 9 and all of equal size or decreasing towards the reservoir; a tapered notch 15 in a web 14 on the feed part 3 extends the duct to the reservoir, and is sufficiently small to produce a membrane of ink by surface tension which normally breaks only to admit air to the reservoir in replacement of ink used. The web 10 which abuts closely against the bottom of web 14 has two vertical slits sufficiently narrow to prevent breakage of the surface tension membrane, but which supplement the notch 15 to allow free outflow of ink when excess pressure arises in the reservoir; the overflowing ink then fills the chambers in succession from the right (Fig. 1) via the duct 13, and also (via the supply duct 17, 19 and a hole 18 in the nib) from the extreme left, the intervening air being exhausted by a hard rubber tube 12 from the chamber 7a next to the web 9. The invention may also be applied to a single-part ink feed, e.g. (a) the notches 13 being in line centrally of the ink feed top (they may have a capillary ink supply tube inserted through them), or (b) the chambers 7a, 7b being cut in upwardly from below and extending round the feed periphery to longitudinal grooves at their ends corresponding to the duct 13, the ink supply capillary then being arranged centrally at th top of the feed.

Filed: 1943-12-06
Abstract: 570,909. Chain gearing. AVELING-BARFORD, Ltd., and PENN, O. S. Dec. 6, 1943, No. 20350. [Class 80 (i)] Consists in means for tensioning two driving chains associated with sprockets rotating about different axes supported intermediately of the driving and driven elements. A drive is transmitted from the shaft A<1> of a prime mover A to a shaft E, by chains C, D engaging sprockets on separate shafts B<1>, B<2> of a gear box B. This gear box is pivotally supported on a cross-head B<3> adjustable by a screw G along a slot in the base F, and at its upper end has an arcuate slot B<5> through which passes a clamping bolt H fixed to a support. To adjust the tensions, the bolt H is slackened and the screw G rotated to move the cross-head inwardly until arrested by the chain D, after which further rotation of screw G rotates the gear box bodily about the shaft B<2> counterclockwise to tighten the belt C, the bolt H then being tightened. In modifications, the chains C, D (1) extend from the gear box in the same direction, (2) are at an angle to one another. As applied to the transmission mechanism of a self-propelled dumper truck, the crankshaft 7 of an internal-combustion engine 6 drives through a sprocket 8, chain 9 and sprocket 10, the input shaft 11 of a gear box 12, the output shaft 13 of which drives the road wheels 3 through a sprocket 14 and chain 15. Two cheek plates 17 bolted to the gear box each terminates in a bearing boss 18 rotatably accommodating an eccentric 19 keyed on a spindle 20 supported at one end by a chassis member 2 and at the other end by a subframe member 21, and surrounded by a tubular distance piece 22. The eccentric is rotatable by an arm 23 and can be locked by nuts 24. The rear end of the gear box has pivoted thereto at 27 a yoke 28 of a rod 29 the lower end of which passes through an apertured block 30 pivoted at 31 in a bracket 32 to which it is secured by a bolt 33. To adjust the tensions, the nuts 24 and bolt 33 are slackened, the eccentrics 19 turned to tighten chain 15 and then turned still further to cant the gear box about the shaft 13 to tension the chain 9. The securing means are then tightened again, a head 20a, Fig. 7, on the eccentric spindle acting as a clamping device.

Title: Improvements in the imprinting mechanism of tabulating and like recording machines
IPC: B41J29/28
Filed: 1947-07-29
Abstract: 642,135. Typewriters &c. STANDARD REGISTER CO. July 29, 1947, No. 20496. Convention date, July 20, 1942. [Class 100 (iv)] In a tabulating or like recording machine having type elements 9 differentially-set for printing a line of type on record material 2 progressively fed around a platen 1, lineprinting elements 27 for producing vertical line rulings on the material 2 are interposed between adjacent elements 9 and can be controlled by selective means so that either simultaneous or independent operation of a line-spacing element 27 with respect to an adjacent character type element can be effected. The ruling device which can be an attachment to or incorporated in the machine comprises brackets 20 on which is mounted a rod 21 carrying a series of levers 22 to which the elements 27, in the form of thin, flat members which can extend between the type elements 9, are pivoted on a screw 26. By pivoting an arm 22 in a clockwise direction, Fig. 3, an element 27 can be positioned alongside the selected type of an element 9 so that when the hammer 10 of that element is released it simultaneously strikes the element 27 and causes part of a line to be printed at the same time as the character. Slidable on each screw 26 by means of a dumb-bell slot 30 is a flat blade 29 which when situated in an upper position, Fig. 3, with relation to the element 27, is outside the path of the hammer 10, but when in a lower position is struck by the hammer to cause the element 27 to make an impression but prevents contact of the hammer with the type so that no character is printed. The blade is held in the raised position by rotating, by means of a handle 32 a flat-sided spindle 31 journalled in the element 27 so that its longer axis lies horizontal in the lower enlarged limb of the slot 30. To render an element 27 inoperative, the slide 29 is first lifted, whereupon the handle 32 under gravity turns the spindle 31 to locking position. The arm 22 is next turned to a vertical position to raise the element 27 and then the handle 32 is turned to unlocking position, whereupon the slide 29 moves downwardly and a curved part 34 thereon engages the rod 21 to hold the parts raised. The Specification as open to inspection under Sect. 91 comprises also a scriber which is spring urged into contact with the papers to form a continuous line as the platen is rotated. This scriber may be moved manually away from the papers by an extension arm formed on the scriber and may be locked in the inoperative position by a detent catch. This subjectmatter does not appear in the Specification as accepted.

Patent GB-206590-A (GB)
Abstract: 206,590. Vidal, A. E., (Optische Anstalt C. P. Goerz Akt.-Ges.). Aug. 9, 1922. Adding and subtracting apparatus; with operating-means.-An adding and subtracting machine in which the totalizing-counter carriage is moved laterally slightly, in order to reverse the drive to change from addition to subtraction, is provided with improved means operated by the subtraction key to effect the required movement of the carriage. The pinion 2 on the totalizing drum is operated directly from the differential actuating sector 1 by a gear wheel 3 for addition, and in the reverse direction from the sector 1 by wheels 4, 5 for subtraction. Normally a roller 12 on to the machine frame touches a roller 13 carried by the totalizing-counter carriage, in which position the sector 1 gears with the wheel 3. When the subtraction key 6 is depressed a bell-crank 10 is operated through a linkage 7, 8, 9 so that a wedge 11 on the bell-crank 10 is forced up between the rollers 12, 13, whereby the carriage is slightly moved laterally and the sector 1 gears through the wheels 4, 5. In the case of large machines where the pressure on the key 6 would need to be considerable, a modified carriage-shifting means is set by the key 6 and the actual moving of the totalizing-counter carriage is carried out later from the main driving shaft 18, Fig. 4, of the machine. The subtraction key 6 is connected to a lever 9<1> having an arm 16 connected by a spring 17 to a link 15 operating the bell-crank 10 and wedge 11; the lever 9' also carrying a pin 14 which rests on the link 15, The shaft 18 carries a disc having a roller 21 so that when the shaft is rotated a bellcrank lever 20 pivoted at 19 is rocked counterclockwise thus moving a link 23, pivoted to it at 24, to the left. This link 23 is connected by a pin 26 and a slot 25 to the arm 16 and also carries a lateral projection 27 co-operating with the end face 28 of the link 15. In order to shift the carriage so as to subtract, the key 6 is depressed, this rocking the lever 9<1> clockwise, thus raising the arm 16 and stretching the spring 17 as the pin 14 rides along the upper surface of the link 15. The arm 16 in rising carries with it the end of the link 23 so that the projection 27 is raised into the path of the face 28. Then, upon the operation of the main shaft 18, the projection 27 is moved to the left, carrying with it the link 15 so that the crank 10 is rocked and the carriage shifted by the wedge 11. The link 15 will have now moved to the left to such an extent that the pin 14 will rest on the step 29 of the link 15, the link 15 being now raised slightly at this end by the spring 17. While the key 6 is kept depressed the pin 14 and spring 17 will keep the link 15 locked in this last position so that the carriage is maintained in the subtracting positon, but upon release of the key 6 the lever 9<1> and link 15 will return to normal positions.
