Granted: 1903-09-10
Abstract: 24,234. Shepherd, E. S., and Bartlett, O. M. Nov. 5. Photo - mechanical printing ; producing coloured photographs.-For preparing multi-coloured photographic prints on paper, opal glass, &c., three chrome-gelatine prints from the colour negatives are made in gelatine on a celluloid or other support. The gelatine may contain some silver bromide, which is afterwards removed by sodium hyposulphite. The gelatine prints are stained with the three colours in baths of aniline dye. After drying, the stained prints are laid, in rotation, on the wetted soft gelatine coating of a piece of paper &c. so as to transfer a portion of the colour from each, in turn. The blue print may be made by a ferro-prussiate process instead of by staining, the other colours being superposed by staining.

Title: Improved Means for Preventing the Breakage of the Warp Threads in Looms for Weaving.
Inventor: BARRON THOMAS HENRY
Filed: 1903-05-23
Granted: 1904-03-24
Abstract: 11,768. Barron, T. H., [Northrop Loom Co.]. May 23. Loom stop-motions; warp tension, regulating letoff motions; back-bearers.-When the shipper L is knocked-off by a lever c<2> and a sliding frog c in the usual manner, on the fail are of the shuttle to enter its box, the warp threads are slackened by unlocking the whip-roll W, so that the lay may move past the front entre without causing a smash. The whip-roll W is mounted in blocks w, which slide in slots m<2> in arms m', loosely mounted on a rockshaft m. The blocks w are acted upon by springs s<x> to allow slight motion of the whip - roll under tension of the warp threads. Arms n fixed to the shaft m carry a controlling rock-shaft o, to which are secured two forked arms n', each carrying a roller n<4>. These rollers may be engaged in one of two positions in slots in arms m<4> secured to the hubs of the arms m<1>. In the position shown in full lines, the rollers are in the lower parts of the slots, and the whip-roll is locked, so that the shaft m rocks with it. An arm W<3> fast on the shaft m is connected by a spring-controlled rod a to the pawlarm c<x> of the let-off ratchet-wheel B<3>, the arm c<x> being actuated by connection with the lay-sword. The starting point of the pawl, and therefore the amount of let-off, thus varies according to the position of the whip-roll, which position is regulated by the tension of the warp threads. When the frog c is moved forward to stop the loom, it acts through a rod n<12> and arm n<10> to rock the shaft o, whereby the rollers n<4> are moved into the higher parts of their slots, and the whip-roll W is unlocked to slacken the warp threads. Simultaneously an arm n<15> on the shaft o is raised, and acts through a rod n<16> and spring to raise the let - off pawl d', and thus arrest the let-off motion. When the lay is moved back to re-start the loom, a bunter c<20> extending from the frog c is engaged by the lay, and the frog is drawn back, so that through the rod n<12> and arm n<10> the shaft o is rocked to its former position, and the various parts are returned to their working positions.

Abstract: 12,801. Compagnie Anon. Continentale pour la Fabrication des Compteurs Ó Gaz et Autres Appareils. Oct. 4, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Energy and quantity meters.-In an induction motor meter, a hollow metal cylinder C rotates in the field produced between laminated pole-pieces P<1>, P<2>, P<3> and a laminated core A. Permanent magnets T may be used as brakes. The shunt circuit e across the mains M includes an inductance coil S and windings p<1> either confined to the polepiece P' or distributed over the three pole-pieces. The main current I divides between an inductance coil S' and a circuit comprising a non-inductive resistance R and the windings p<2>, p<3>. According as a magnetic brake is used or not, the meter serves as an energy meter or a register of useful amperehours. In order that the direction of rotational effort of the disc C may be determinate, and to overcome the constant frictional resistance, one of the pole-pieces P<2>, P<3> is made of slightly smaller cross-section than the other, or its air gap is made slightly larger. For two-phase or three-phase work, two separate magnetic systems with a common moving part are employed.

Title: Improvements in and relating to Electric Motors.
Inventor: ZWEIGBERGK THORSTEN VON
Filed: 1904-04-14
Granted: 1905-04-13
Abstract: 8620. Zweigbergk, T. von. April 14. Motors, controlling.-Motors running on an alternating-current supply are started with the torque of direct-current series motors by arranging in a local circuit a, in which there is a source of direct current D, one or more pairs of motor armatures A, B which may or may not be on the same shaft, and choking-coils A<1>, A<2>, B<1>, B<2> which may or may not be the divided motor field windings, and the individual pairs of which are in the same magnetic circuit. This local circuit is connected to an alternating-current supply C, so that only one coil of each pair is in each of the two parallel circuits A', A, B<2> and B<1>, B, A'. As one member of every pair balances the other member, a path with practically no self-induction is provided for each pulse of the alternating current, and the armatures in the two branches of the local circuit are accelerated alternately, the balanced system effecting a selection whereby one set of motors is supplied by practically all the current in one direction and the other motors by the current in the opposite direction. The system may be applied to other types and combinations of motors than that particularly described.

Title: Improvements in Machinery or Appliances for Bevelling, Grinding, Polishing, and other Wise Surfacing or Abrading Parts of Glass Plates, Lenses, and analogous Articles
Filed: 1904-04-28
Granted: 1905-01-26
Abstract: 9702. Pearce, Ltd., W., and Griffiths, A. April 28. Lenses.-In a machine for use in bevelling, grinding, polishing, and otherwise surfacing parts of glass plates, lenses, &c., the work-holder is supported by a trunnion-mounted carriage which is suspended by a system of springs from a rigid head. Fig. 1 is a side elevation, and Fig. 4 an end elevation showing the means by which the spring- suspended parts may be tilted or angularly adjusted. The head a, which supports the rest of the machine, may be swung round in a horizontal plane by worm and segmental rack gearing c and a handwheel c<3>. The slide d, which may be vertically adjusted in the head a by the screw d', supports the guided frame e by springs g, h, and to this frame is bolted the main bracket f in such a way that the bracket may be adjusted angularly by the segmental rack f and worm gearing f Fig. 4. The shaft i, supported by the other end of the bracket f, carries the carriage n with work-holders and gear so that they can move bodily in a vertical plane, this movement being limited by the arm k engaging the stud m. The lens &c. is carried between clamps o, p, of which o is mounted in a fixed arm o<1>, while p is supported by a movable arm p<1> so as to open and close the clamp. Both clamps can turn at o<3>, p<3> so as to permit the rotation of the lens by means of the band-wheel and worm-gearing u. The carriage u comprises a lower part, provided with sleeves q', which can be reciprocated on the bars q, carried by the upper part of the carriage, so as to adjust or oscillate the arms o<1>, p<1> supported by the lower part of the frame. This is effected by the rack and pinion s', s<1> the latter being rotated by a hand-lever or by the arrangement shown, in which the lever s is mounted loosely on its shaft but carries a second lever t<3> so that, by depressing this, the bolt t<3> can be disengaged from the holes in the clutch-collar t<1>. The pinion s' can thus he rotated in either direction to any extent by oscillating the lever s. When dealing with circular or oval lenses, during the rough-grinding operations, the lens is rotated by the gearing u, the traversing gear s, a<1> being employed only during the smoothing and polishing processes. When bevel-grinding or polishing the edges of oval or elliptical lenses, the edge of the lens, while being rotated by gearing u, is made to traval over the mill, and during the process the rocking-carriage n is alternately raised and lowered by an attendant, in synchronism with the rotation of the clamps and lens.
