Abstract: 25,988. Johannet, M. Dec. 4, 1905, [date applied for under Patents Act, 1901]. Distributing.-The couple and speed of the driven shaft of a dynamo. motor system of transmitting power from a constant - speed prime e mover are varied by automatically cutting in or out sections of the motor field winding by means of an electromagnetic switch. The driving-shaft 1, Fig. 1, rotates the field magnet 2 of the generator, the armature 4 of which is keyed upon the driven shaft 5 carrying also the armature 6 of the motor, the field magnet 8 of which is either fixed or movable. In the latter case, the field magnet is connected by bevel-gearing to the shaft 5 so as to add its motive effect to the latter. The generator and motor are arranged in series, Fig. 2, sections of the motor field winding being cut in or out by means of a series electro-magnet 9 acting against a spring 19 and dash-pot 23. At starting, the switch contact 20 rests upon the stud 10 and short-circuits the motor. The drag of the motor armature upon its field magnet may be utilized for cutting in and out turns of its field windings. As shown in Fig. 3, the field magnet is arranged to turn round the shaft 5 in opposition to a spring 24 to cut in or out sections of its field winding 8, the short-circuiting-contact 10 of Fig. 2 being replaced by a series electro-magnetic switch 22<1>.

Title: Improvements in and relating to Perforation or Division of Paper or other Sheet Material.
Inventor: KARFIOL BENZION
Filed: 1907-01-07
Granted: 1907-06-06
Abstract: 445. Karfiol, B. July 5, 1906, [date applicd for under Patents Act, 1901]. Embossing.-In an apparatus for perforating paper and other sheet material for the manufacture of paper lace, ornamental paper &c., dress patterns, &c., the paper &c. is first embossed to form projections, which are then cut off to leave perforations. For forming paper lace, one, two, or more sheets of paper are passed from rollers 2, 16, Fig. 1, over idle rollers 3, 4 and between rollers 5, 6, 7, of which the roller 6 is of hard metal and is formed with a raised pattern which is to be embossed on the paper. In the form shown, the roller 6 forms a series of pyramidal projections, arranged in a design, on the paper. The roller 7 is a matrix roller, and is a counterpart of the roller 6. The roller 7 is usually of soft metal, and is formed from the roller 6 by rolling engagement under pressure. The embossed paper is then led past a rotary abrading or catting wheel 8, against which the paper is resiliently held by any pressure device such as a bent spring piece 9 mounted on adjustable supports 10, 11. The wheel 8 cuts or grinds off the projections formed in the paper, and thus forms holes or perforations in the paper. The roll 7 may emboss the paper lace on the reverse side to that on which the projections are formed by the roller 6. The paper is wound up by a roll 14. For cutting- out dress patterns, the roller 6 is formed so as to indent the paper along the line of the pattern, leaving a few breaks in the indent, as shown in Fig. 6, to maintain the pattern in the sheet until it is desired to detach it.

Patent GB-190709321-A (GB)
Title: Improvements in and relating to Machines for Wrapping Up Blocks of Material and for Stacking them in Piles
Inventor: BRADY JAMES HENRY
Filed: 1907-04-22
Granted: 1907-09-26
Abstract: 9321. Brady, J. H., and Keller, D. A. April 22. Cutting-machines for paper.- In a machine for wrapping up blocks of chewing-gum, chocolate, &c., two webs of wrapping-material drawn from rolls 8, 9, Fig. 2, pass under a spring-pressed piece 13 and then under a spring-controlled plate 19 arranged to prevent rearward movement. The webs are fed forward by a hooked folding-blade 32, which first folds the free ends of the webs over the block to be enclosed, and then, as it moves to the right, pulls the block and web with it. Before passing upward through a hole 29 in the bed of the machine, the webs pass an electric apparatus, which controls the wrapper severing-blade. The lower web has perforations, slits, or notches arranged in it at intervals. When the spring- pressed finger 26 comes opposite one of the perforations, it rises and allows the contact-piece 27 carried by it to close an electric circuit. The magnet 76, Figs. 2 and 6, is thus energized and the catch 77 carried by its armature rises, and allows the pivoted blade 31 to be pulled down by a spring 31<1>. In order that the electric circuit may not remain closed during the entire period of contact of the parts 27, 28<a>, there is arranged in the circuit a contact-point, which is carried by a rotating shaft and makes intermittent contact with a plate or brush. The cutting-blade is restored to its raised position by a reciprocating cam 78, Fig. 7, engaging with a roller 80 on the cranked end of the knife-shaft 79. To ensure operation of the knife if there is an accidental absence of a perforation in the web, mechanical means are provided for tripping the catch 77. Frictionally held in a tubular bracket 83, Figs. 6 and 7, mounted on a sliding carriage, is a shaft 84 carrying an arm which has at its upper end a piece 88 adapted to engage with a fixed cam 89. When the sliding carriage moves in one direction, the cam 89 causes a roller 86 carried by the arm 85 to trip the catch 77 if it has not been tripped already by the magnet. When the carriage 3 moves in the other direction, the roller 86 moves clear of the extension 87 of the catch 77. A guard rod prevents the knife from descending before the blade 32 has passed it.

Granted: 1908-02-27
Abstract: 11,198. Haywood, T. E., and McKenzie & Holland. May 14. Frame pulleys.-Relates to means for supporting the frames of pulleys for carrying railway. signal wires and the like so that they may be set at any angle. A frame 1, Fig. 2, having lugs between which the pulley-wheel is suspended, has arms 4 bent to receive the head of a T-shaped bolt which passes between the arms. A block 6, fitting a recess or corrugation in the stake 3, has curved surfaces which may be drawn against corresponding surfaces on the arms 4 by means of a T-headed bolt 5. The block 6 has top and bottom extensions to prevent the frame from turning. In a modification, lugs 8, Figs. 4, enclose the pin 10 on which an eye-bolt 9 turns. In other modifications, the block 6 may be attached by means of a screw or a projection engaging a recess on the stake. To prevent the pulleys from rubbing against the sides of the frame, the bosses 13 are made wider, while the diameter of the pulley is larger than usual. According to the Provisional Specification, the stake may be made of corrugated steel and may be sufficiently wide to carry several sets of pulleys.

Granted: 1907-09-19
Abstract: 14,079. Felten & Guilleaume-Lahmeyerwerke Akt.-Ges. June 18, 1906, [date applied for under Patents Act, 1901]. Drawings to Specification. Distributing.-Electro-mechanical power-transmission systems of the kind described in Specification No. 20,561, A.D. 1902, [Abridgment Class Locomotives &c.], in which the slip current of a dynamo employed as a clutch between a constantspeed prime-mover and a driven shaft is passed into motors for resisting the driven shaft, are modified for propelling ships, trains, &c. One or more vehicles or propeller shafts are fitted with dynamoelectric generators, while another or more vehicles or shafts are fitted with electromotors fed from the generators, large variations in speed of the driven members being obtained by coupling up the generators and motors in series, in parallel, or in series-parallel, and by varying the field excitations. In the speed-control arrangements, some or all of the motors may be cut out, and the armatures of the generators may be closed on themselves and connected in series-parallel arrangements, the field windings being similarly combined. The driven shafts may be reversed without touching the prime-movers, by reversing the motors and operating the dynamo clutches as ordinary generators with stationary field magnets and revolving armatures, or, in some cases, by exciting the motor fields to only a slight amount.
Patent GB-190716207-A (GB)
Title: Improvements in Presses for Wearing Apparel and Household Linen, for use in Cementing Articles Together, for Shaping Articles of Straw, Felt and the like, for Copying Documents, and for other like purposes.
Inventor: HARVEY LEWIS JOHN THOMAS
Filed: 1907-07-15
Granted: 1908-06-18
Abstract: 16,207. Harvey, L. J. T. July 15. Presses; trouser presses; linen presses.-Presses for wearing- apparel and household linen, for use in cementing articles together, for shaping articles of straw, felt, &c., for,copying documents, and for other like purposes, are constructed so that they may be adjusted to accommodate different thicknesses of material, without having first to secure or release a screw, bolt, or catch. Fig. 1 shows part of a press for copying documents, in which B is the usual bed-plate, C the resistance bar, E the pressure plate, and A one of the end pillars. The bar C is mounted to slide loosely on the pillar A, which is flanged to engage beneath the plate Band is secured to it by screws. The pillar A is serrated, and is adapted to be engaged by a wedge D, Fig. 4, which passes through the hole in the end of the bar C and, when the press is not in use, rests on a bracket F screwed to the plate E. Pins G, G', Fig. 4, prevent the wedge from falling out of its place. To adjust the press, the plate E, wedge D, and bar C are merely lifted as a whole, but, when the pressure-mechanism is put into action, the plate E remains stationary, while the bar C rises until the wedge engages the pillar A. Further actuation of the pressure mechanism then forces the plate E downwards towards the bed-plate B. Instead of the wedges D, one or more balls, rollers, ratchet-clicks, or detents, actuated by gravity, springs, or other means, may be used. Fig. 8 shows the invention applied to a trouser press, in which each pillar A is loosely fitted with a separate resistance block C, to which is pivoted an eccentric actuating-handle K. When this is raised, the block C rises in the pillar A until the wedge jams, and then the eccentric presses on the bracket F to clamp the plate E against the bed-plate. The pillar A is hinged to the bed-plate, and may be turned down to the horizontal position through a slot in the bracket F.

Abstract: 19,500. Fawns, K. E., and Kermode, G. Aug. 30. Tickets, issuing.-Relates to sale apparatus for stamps, tickets, &c. of the type described in Specifications No. 25,875, A.D. 1904, [Abridgment Class Coin-freed apparatus &c.], and No. 13,587, A.D. 1906, in which a strip of stamps &c. is fed from an intermittently rotated sprocket wheel having spacing pins to a delivery aperture. According to the present invention, the manually-operated slide is dispensed with, the insertion of the coin effecting the setting of the mechanism, and special means are provided for preventing fraud and adapting the mechanism to be operated only after the insertion of several coins. The coin inserted in a slot 2 engages an arm 13<a> rocking a shaft 13, and, through a link 12, raising a weight 11 and turning a quadrant 10 which is loosely mounted on a shaft 6. A pawl 31 on the quadrant is thereby lifted on to the next tooth 30 of the sprocket wheel 5, which is fast on the shaft 6. If of correct denomination the coin is directed on to an arm 22 of a spring- controlled detent spindle 23, rotating the latter and withdrawing the lock. ing-portion 25 from an arm 26, which is carried by a pinion 28 gearing with a wheel 9 or the shaft 6. The weight 11 now falls the pawl 31 rotat ing the sprocket wheel and feeding a stamp &c. through the delivery aper ture which is pro vided with serrated edge to facilitate severance. An arm 45 on the weight drops behind the next pin, locking the sprocket wheel. When the stamp strip is exhausted, a plunger 35<a> passes through an aperture 36 in a bracket 35, drawing down a slide 40 through links 38, 39 to close the coin slot and display an 'empty' notice.
Patent GB-190722735-A (GB)
Title: Improvements in Governing Mechanism for Turbines.
Filed: 1907-10-15
Granted: 1908-06-25
Abstract: 22,735. Warwick Machinery Co., [General Electric Co.]. Oct. 15. Elastic-fluid turbines; fixed-abutment type of rotary engine with oscillating vane. Spring-pressed inlet valves are opened by cams on a shaft actuated by an hydraulic oscillating-vane engine, the control valve of which is operated by the turbine governor. A follow-up device is also provided. Two batteries of valves may be operated by the same motor. The upper end of the shaft 7, which is common to the turbine in the casing 1 and the generator in the casing 3, carries a centrifugal governor 6, which acts on a rod 11 through a spring in the case 9, and through a lever 10. A movement of the rod 11 reciprocates the valve - rod 44, Fig. 3, of the operating-motor 20, the lever 45 pivoting about the point 50. The shaft 15, connected directly to the motor shaft, has cams adapted to raise the spring-pressed turbine inlet valves 19 by means of forked levers 16, Fig. 2, hinged at one end to a rod 17 and fitted with a cam roller 18 at the other. The shaft 15 and motor 20 are carried by a bracelet 14 on the steam-chest 13. Fig. 4 shows the construction of the motor casing. The oscillating piston vane 26 is formed of Babbitt-metal to allow of it being hammered out to take up wear, and is retained in place by screws 27, the Babbitt-metal being cast round the screws. The steel hub 25 is previously turned to the desired dimensions. A compression spring 30 ensures a tight fit at the bevelled running joint 28. The connexion between the hub and the shaft 15 consists of a pin 32 engaging slots in the ends of both parts. It is secured to the hub 25, and also serves to limit the movement of the motor piston by coming into contact with stops 33, 34. The pilot valve 35, which may be formed integrally with the head 23, or bolted thereto, contains a bushing 36 having ports 37, 38, 40. Pressure liquid, which may be from the source of supply of lubricant for the stepbearing of the turbo-generator, is introduced by a pipe 41. Passages 42, 43 connect the ports 37, 38 with the lower and upper side respectively of the fixed abutment 39. To prevent sticking of the valve 44, the pistons are turned down to leave narrow flanges 46 in order to reduce the area exposed to side thrust. An upward movement of the rod 11, and consequently of the valve-rod 44, allows high-pressure liquid to pass to the lower side of the piston through ports 40, 37, and a passage 42. The piston and cam shaft commence to rotate, and the follow-up device comprising a pinion 47 and rack 48 at once comes into action, and closes the ports 37, 38 by depressing the lever 45 about the point 50<1> as a fulcrum. A similar action takes place when the governor depresses the rod 11. When two batteries of inlet valves are fitted to the turbine, the second cam shaft is actuated by a rack 52 driven by a pinion 51 on the first shaft. The racks 48, 52 are kept in gear by combined guides and rollers 49, 53 respectively.
