Title: Improved wire-straightening machine
IPC: B22C21/14
Filed: 1942-11-12
Abstract: 561,380. Sorting articles. FORD MOTOR CO., Ltd., and LEEK, J. W. Nov. 12, 1942, No. 16013. [Class 117] [Also in Group XXII] A wire straightening machine, particularly for straightening core wires after removal of the cores from castings and prior to re-use, comprises a swage with a groove or channel through which the wire is fed and which receives a rapid succession of blows from a spring- loaded hammer as the wire is fed therethrough. The wire is fed by hand through a channel c in a twopart swage b which is acted on by a hammer d operated by an eccentric through a connecting rod g with spherical end g<1> held in a similar cup h by means of a loaded spring i. The entrance and preferably also the exit end of the channel are bell-mouthed and the channel is flanked by two vertical rollers c<2> to prevent damage to the wires by the split in the swage. The channel is relieved at c<1> to facilitate straightening. After passing through the swage the end of the wire is gripped by two spring-loaded feed rolls k<1>, k<2> adjustable by a member k<3> and driven by spring-compensated mechanism l to avoid wear on the rolls when the wire is held by the swage. The wire then passes through a two-part guide m, the lower part of which is carried by a spring- controlled link m<1> and lever m<2> operated by a handle m<3> so that it may be lowered to allow the wire. to fall into a hopper n slotted at n<1> so that the wires fall one at a time in front of a cam and lever-operated pusher o which pushes them one behind the other over a plate p having slots p of different lengths so as to sort them according to length into appropriate containers r. A number of hammers and swages may operate simultaneously on a number of wires, the channels in the swages, if desired, being of different sizes to suit wires of different gauges.

Title: Improvements in and relating to typewriters
IPC: B41J19/46
Filed: 1949-06-16
Abstract: 669,593. Typewriters &c. PAILLARD SOC. ANON. June 16, 1949 [June 25, 1948], No. 16050/49. Class 100 (iv). Machine framework.-A typewriter with a transversely movable carriage has a removable support 1, fixed to the typewriter framework behind the carriage slides, carrying the escapement, the carriage return spring 2, means for engaging and disengaging the margin stops, means for blocking the type-levers at the end of a line, means for engaging and disengaging tabulator stops, means for releasing the carriage, means for braking the movement. of the carriage and means for operating the warning-bell. The support 1 may be resiliently fixed to the framework. Carriage margin stops and locking devices.-Margin stops at each end of the carriage are arranged to abut a stop 8 pivoted and slidable on a spindle 8a carried by two projections 7 on the support 1. When it is required to type beyond the right-hand margin stop the stop 8 is pivoted by means of an extension arm 13 linked at 12 to a connecting rod 11 operated from a key on the keyboard. At the end of a typed line the engagement of a margin stop with the stop 8 moves it leftwardly on its spindle against the pressure of a spring 9, and a lug 41 projecting from the lower side of the stop 8 thus permits anticlockwise movement of a lever 39 by pull of a spring 43. A part 42 of the lever 39 is thereby moved into the path of an oscillating arm 21 integral with an escapement pawl assembly 22, 23 and so prevents movement of the arm 21, and thereby locking the escapement wheel 3. Carriage releasing.-Tabulating stops 14 on the carriage engage with a stop 16 on a vertical slide 18 operated by a key on the keyboard. The slide 18 has a protruding lug 35 which engages one arm 36 of a bell-crank lever and causes the other vertical arm 37 of the bell crank to engage a support 38 carrying the carriage rack 5 which is thereby moved out of engagement from a pinion 4 of the escapement mechanism. Carriage brakes.-The extremity of the arm 37 carries a braking element engaging and slowing the movement of the carriage when released from the escapement mechanism. Back-spacing.-The carriage is back-spaced by the operation of a key connected to a link 20 actuating a lever 19 which rotates the escapement wheel 3 in opposition to the advancing pull of a spring drum 2. Specification 659,342 is referred to.

Abstract: 915,371. Making and applying handles to paper bags. WINDMOLLER, A., and GENNERICH, M., [trading as WINDMOLLER & HOLSCHER]. May 14, 1959 [May 14, 1958; Dec. 31, 1958; April 6, 1959], No. 16584/59.. Class 133.  A machine for making handles from a strip of paper and applying them to paper bags comprises a cylinder 58 to which a length of strip with the edges folded in and stuck is supplied from an oscillating holder 55 and gripped at its central region by a gripper 59 or 60, folding means 69, 70 for folding the end portions of the strip backwards at right angles to the central grip portion so that the folds are above the central grip portion, and a second cylinder 73 rotating in the opposite direction to the cylinder 58 which takes over the handle so that the folds are below the central grip portion. The ends are gummed at 79 and stuck to bags supplied to a belt 84 and fed to the cylinder 73 by devices 86, 87. Handles for the other sides of the bags are formed and applied by identical mechanism. A strip 23 of crepe paper is drawn by feed rollers 21, 22 from a spool 24 and runs through smoothing mechanism 25, 26 which flattens out the creping at the handle end portions, mechanism 27, 28, 29 for applying adhesive along its margins, mechanism 30 for folding over these margins thus doubling the strip's thickness and a 'grooving mechanism 31, 32 which forms grooves extending diagonally from the edges, on each side of the strip for the corner folds. The strip then passes through a cutting mechanism 33, 34 which does not completely sever it but leaves two thin webs between each successive handle length, and through feed rollers 35, 36 and 37, 38 the latter being segmental and rotating at a relatively higher peripheral speed so that it separates the leading handle length from the following one. The handle now passes under pairs of rollers 39, 46 and is halted by a detent 47 when the upper roller of each pair is raised; while stationary, the handle is penetrated by needles 48, 49, 50, see Fig. 13, arranged to perform a swinging movement (as arrow 57) by which it is transferred to the cylinder 58 and gripped thereon by grippers 59 or 60, its centre being located over folder pincers 61 or 62 which fold this portion double when these pincers coincide, during the cylinder's rotation, with a rotating folder knife 64, and the handle is then released from the grippers. Further mechanisms bend back the side portions of the handle, aligning the folds precisely; the handle, now being turned about, has adhesive applied and on meeting the bags being conveyed below the cylinder 73 and above the cylinder 80, adhesion of the handles to both sides of the bag is effected simultaneously, and the finished article is conveyed to a stack 81. In a modification, the handles are reinforced with bast bands which are introduced into the strip from a separate supply spool. Cover sheets may be stuck over the ends of the handles and on to the bag bottoms.
