Title: Improvements in or relating to hair curlers
IPC: A45D2/04
Filed: 1921-10-27
Abstract: 191,864. Aldworth, G., and Hornett, A. C. Oct. 27, 1921. Hair-curling appliances.-A curler for permanent hair-waving comprises a tube, a plug partly projecting from the end of the tube, and a member frictionally engaging the inside of the tube and connected to the inner end of the plug in such a manner, as by a pin, hook, or screw-thread, &c., as to prevent longitudinal movement of the plug. The tube a, Figs. 1 and 4, has secured thereto a head b having a conical interior surface, into which fits a conical plug c, the outer part of which is slotted. Secured to the inner end of the plug c is a bent strip e, Fig. 1, of spring metal with a second strip e<1> secured thereto, both strips engaging the inner surface of the tube a; or a single wavy strip e<2>, Fig. '4, engaging the tube a at several points, is provided. The frictional members e, e<2> are secured by pins b<2> passed through the end of the plug c and bearing against the head b, so preventing withdrawal of the plug. The friction member may extend beyond the end of the tube so that it may be gripped to hold the plug stationary while the tube is turned, and adjusting means, such as a nut f, Fig. 4, engaging a rod e<5> attached to the strip e<2>, may be provided to vary the degree of engagement. In the construction shown in Fig. 1, a link or wedge device or a sliding ring may be used for the same purpose. Other forms of friction member may be employed. Fig. 6 shows a modification, in which a conical member c<2> engages with a liner a' and is connected to the plug c by a rod c<3>, which is screwed either into the plug or into the conical member, so that, by turning the member c<2> by means of a screw-driver, the degree of frictional engagement may be varied and longitudinal movement of the plug prevented.

Title: Ink roller arrangement
IPC: B41F31/30
Filed: 1951-12-06
Abstract: 723,007. Printing-machines. GOSS PRINTING PRESS CO. Dec. 6, 1951 [April 20, 1951], No. 28646/51. Class 100 (2). Inking apparatus.-In a printing press having a pair of rigid cylinders in spaced parallel relationship, a rubber inking roller contacting both cylinders is carried by bearing blocks simultaneously movable in frames along a straight line path towards and away from the cylinders, and manually adjustable means on the blocks are provided adapted to co-operate with a fixed surface on the frames for adjusting the blocks to a desired operative position in which the roller rides in contact with the cylinders, the frames being so oriented that the roller remains substantially equidistant from both of the cylinders during the adjusting movement. The adjustment means of the bearing blocks of ink rollers varying by Œ“ inch of a specified nominal diameter may be pre-set while the roller and blocks are removed from the printing-machine, thus enabling ink rollers to be quickly exchanged; a jig for pre-setting is described. The invention may be applied to rubber rollers arranged between two ink drums, or, as shown in Fig. 1, to two rubber rollers 11, 12 arranged between an ink drum 13 and a plate cylinder 10. The roller shafts are carried. in ball-bearings 28 recessed into bearing-blocks 22 slidable in frames 20, Fig. 4, screwed to the press frame 21; adjustable stops 25 with locknuts 27 are screwed into the blocks 22 and are caused to abut against plates 26, secured to the frames 20, by springs 32 acting on plates 34 carried by clamps 30 hinged at 31 and held closed by nuts on swivel bolts 291; the rollers 11, 12 may be retracted, against the springs 32, by double cams 40 which act on the surfaces 42 of the blocks 22 and are pinned to a manuallyrotatable shaft 41 extending across the press. The bearing-blocks 22 slide in a straight line path such that the roller axes move approximately on the hyperbolic locus of true equidistance from the cylinders 10, 13; the nominal radii of the rollers 11, 12 are such that the line joining the centres of the cylinders 10, 13 subtends angles of 120 degrees and about 106 degrees at their respective centres, so that variations of their actual radii will require respectively a 2: 1 and 1<SP>2</SP>/ 3 : 1 shift of the bearing- blocks. The jig shown in Fig. 6 enables the adjustment for this to be made with the roller and bearing-blocks out of the press: pedestals 62, 63 slidable along ways 61 on a bed 60 have machined wells 64, 65 to receive the bearing-blocks, and dial indicators 66, 67 show the adjustment of the stops 25 while an indicator 71 on a slidable support 70 shows the roller radius; the indicator 71 may be geared, or have a modified scale; to allow for the 2: 1 or 1<SP>2</SP>/ 3 : 1 ratios referred to above so that correct adjustment is obtained when the three indicators show the same reading. The jig indicators are first calibrated using a reference roller whose actual radius is the nominal radius and whose stops 25 have been set in the press to the correct position as established by known tests.

Title: Improvements in or relating to electric relays
IPC: H02H3/093
Filed: 1932-10-13
Abstract: 408,956. Electromagnetic relays. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Smith, R. M. ; 12, Abbott Place, North Arlington, New Jersey, U.S.A.) Oct. 13, 1932, No. 28648. Convention date, Oct. 13, 1931. [Class 38 (v).] An overload relay which is capable of adjustment to obtain a substantially uniform inverse time-current characteristic over through the entire operating range comprises currentresponsive electromagnetic means adapted to operate the relay contacts which are biassed towards the closed position and are held from movement until an electrical quantity such as the current reaches a predetermined value and damping or timing means associated therewith, a resilient coupling being interposed between the electromagnetic operating means and the timing mechanism. As shown in Fig. 2 the relay contact 14 is carried by the armature 9 of the operating electromagnet 2 which is energized by the load circuit, a spring 21 having a substantially constant force biassing the contact 14 towards the fixed contact 16. The armature is connected by a spring 27 to a pivoted arm 31 secured to a ratchet wheel 42. On rotation of the ratchet wheel in an anticlockwise direction pawls 43 are engaged and drive through gearing 44, 45 an eddy-current braking disc 46 movable between the poles of permanent magnets 52. The arm 31 is however connected by a link 83 to the pivoted armature 65 of an initiating electromagnet 59, a powerful spring 77 normally holding the parts in the position shown and preventing movement of the armature 9 of the timing mechanism. On the occurrence, however, of a predetermined current strength the electromagnet 61 attracts its armature and frees the operating and timing mechanism. The various factors controlling the speed of the contact closure are each separately adjustable, viz., the pull of the magnet 3 by tappings 81, the strength of the spring 21 assisting closure and the amount of retardation of the timing mechanism by adjustment of the magnetic circuit of magnets 52 so that any desired inverse-time characteristic throughout the entire operating range may be obtained. Adjustment of tappings on the initiating electromagnet 61 may be utilized to vary the range of operation, and this element may alternatively be made responsive to voltage or impedance.
