Granted: 1904-06-02
Abstract: 9942. Boutillier, L. Aug. 14, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Gas-producers;mechanical stoking.-In a furnace for producing a gas of inferior quality free from tar, a vertical retort 11 to contain the fuel is placed in the hottest part of the furnace, having its upper end at or a little below the lower level of the incandescent fuel 21, which is contained in a metallic casing 1 having a cylindrical lining 7 of fireclay ; the fuel is supported on a grate 4, and the ashes are discharged past a door 5. The combustible is introduced into the retort either by a screw 15 connected with a hopper 16, or it is fed into the pipe 17, and forced up into the retort by a piston 12, a damper 13 being opened for the purpose. The material is fed into the retort at such a rate that it is not forced out, to mingle with the incandescent fuel 21, till it has parted with all its hydrocarbons. A suitable mixture of steam and air is admitted by a pipe 10, and the gas produced passes out by a pipe 9. In starting the producer, a charge is fed in through a hopper 8 and the material to be distilled introduced into the retort 11. If desired, air may be admitted by the stopper 18.

Title: Improvements in and relating to Paper Bag Making Machines.
Inventor: PARR ALFRED
Filed: 1904-05-04
Granted: 1904-11-03
Abstract: 10,278. Parr, A. May 4. Paper bags.-Relates to improvements in the machine, for making square-ended paper bags, described in Specification No. 23,162, A.D. 1892, and consists chiefly in providing means whereby the bags are removed from the former and fed to the flattening-device automatically, instead of by hand. Instead of the form 1, Figs. 1 and 4, being arranged upon a swinging arm, it is carried by a slide 3 which is oscillated vertically by the pivoted rod 23 driven by the cam 25. The finished bag is removed from the form 1 by the stripper 26 on the rod 7, which is operated by the toothed pinion 10. This pinion is driven by the rack 15 which is oscillated by the cam 17 on the countershaft 16 driven, by toothed gearing, from the main shaft c'. The stripper 26 deposits the bag directly on the travelling apron o ; the bag is then in position to be acted on by the creasing-device carried by the arm P operated by a cam on the shaft c<2>. The upper side of the projecting end of the bag, instead of being closed by an arrangement acting in conjunction with the swinging form, is closed by a piece 35 which is oscillated vertically by rods 29, 28 driven by a cam on the countershaft c'. The plate E is horizontal instead of vertical, and the paper blanks are gummed by hand instead of by machinery. Bags of a larger size may be made by replacing the former 1 by another of larger crosssection, the same stripper being used. The rod 7 may be made in two parts supported in guides, the stripper being pulled inwards by weights or by springs 39, 40, Fig. 5, encircling the guide-rods 37, 38. The parts of the rod 7 are then so arranged that their centre-lines are coincident when the form 1 is in its highest position of rest.

Granted: 1905-08-29
Abstract: 16,760. Gercke, H. July 31, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Compasses, magnetic.-A device whereby dissimilar magnetic poles are constrained to remain opposite one another is arranged by mounting one magnet a on a spindle b, which is carried on a pivot d on the top of a spindle e as shown, and to which is fixed a projecting contact-piece m. To the spindle e a slip ring 3 and a ring h of insulating- material are attached, and the spindle turns in the commutator p the segments of which are connected to the coils of the electromagnets i arranged in a ring around the yoke k ; the coils are also connected to the terminal 4. The ring h carries the spring l in contact with the spindle b ; it also carries the spring arms o, the lower ends of which bear against the commutator p and the upper contacts of which stand on either side of the contact m. The spindle e carrics the armature g, one end of the winding being connected to the spring l and the other to the ring 3 and so through the spring 2 to the terminal 1. The terminals 1, 4 are connected to the poles of a battery, and, if the magnet a moves in either direction, the block m will make connection with one or other of the contacts u, u<1>, and close a circuit through the armature g and certain of the electromagnets i- The armature g then turns, moves the magnet a back, and, directly this has passed the similar pole of the opposing magnet q, its movement is accelerated, contact is broken, and the opposite contact is closed. The process is then reversed, and the double cycle repeated so that the like poles of relatively movable magnets are continually playing opposite one another.

Patent GB-190507102-A (GB)
Title: Improvements in Pressure Reducing Valves.
Inventor: HUMPHREY HERBERT ALFRED
Filed: 1905-04-04
Granted: 1905-05-25
Abstract: 7102. Humphrey, H. A. April 4. Reducing - valves.-A pressure - reducing valve comprises a relatively revoluble valve body and sleeve enclosed between flexible diaphragms and having ports which register more or less completely according to the fluctuation of pressure within the diaphragm chamber by means of links connecting the movable part of the valve with the diaphragms. A cylinder c, having lateral slits c', has one end connected to the inlet pipe ; the other end is closed. A sleeve d, with similar lateral slits d<1>, is revolubly mounted on c. The position of the sleeve d is regulated by the links i, which are actuated by the diaphragms e. When the pressure is normal, the gas enters the body c, and passes through the coincident ports into the chamber and thence through the outlet pipe. The springs m tend to keep the valve open. If the pressure in the chamber exceeds the normal, the diaphragms are displaced away from the centre, and the sleeve is rotated, thus cutting off the gas supply. This position is shown in dotted lines. When the fluctuations are likely to be rapid, the communications between the spaces p and the atmosphere are made small so as to damp the motion of the diaphragms. In the form shown in Fig. 1, these communications n are connected by piping o, and a regulating-tap may be used at the junction of the piping. The springs m may be differently arranged.

Lifts; lifting by lazytongs links; fire - escape type of apparatus.-Consists of a lift for use as a fire-escape &c., mounted on a wagon and operated both by lazy-tongs apparatus and by a telescopic standard, which is raised by fluid pumps. Two parallel sets of lazy-tongs G are connected by a number of horizontal bars G<2>, to which are attached tension springs I, tending to raise the apparatus. The two lower cross-pieces of each lazy-tongs frame are pivoted to two segmental worm-wheels D, which are mounted on a shaft C and rotated in opposite directions by worms to raise the lazy-tongs, the motion being transmitted from a handle N<1> through a sprocket-wheel N', chain N<3>, shaft F, and bevel and spur gearing. The shaft rotated by the handle N' is provided with a spring-actuated clutch N<5> and with eccentrics N<6>, which operate pumps for forcing fluid from a tank M into intermediate chambers in the base A, and thence through pipes into the telescopic standard 0, O<1>, O<2>, O<3>. A return pipe P<4>, having a valve P<5>, allows the fluid to flow back into the tank M when the escape is being lowered. The lazy-tongs frames and the telescopic standard are connected together by rods Q', O<8>, fixed at their ends in pivoted brackets. The apparatus is steadied at the base by pivoted arms K, L<4>, provided with screws for clamping to the ground. The arm L<4> is pivoted to a brace L, the ends of which are pivotally connected to the end of the shaft C and to a bracket C<1> on the base A. A guywire L<6>, fixed at one end to the top of the lazytongs frame, is wound round a spring roller L<3> on the brace L, and unwinds as the frame is raised, thereby steadying it. The top members of the lifting-frame are provided with rollers, which move inwardly or outwardly in slotted lugs H' on a platform H. The latter is also supported on the top member of the telescopic standard, as shown in Fig. 4. An upper platform T is capable of being rotated by a hand-wheel T<5> through spur gearing, and is provided with a bridge U, which has an extensible frame U<5> and sliding side-pieces, and can be thrown out by means of a hand-wheel V<5> and a rack and pinion.

Title: Improvements in Combustion-products Engines.
Inventor: MARCILLE MAURICE
Filed: 1905-09-14
Granted: 1905-12-21
Abstract: 18,556. Marcille, M. Sept. 14. Furnace-gas engines.- Reference is made to Specification No. 17,941, A.D. 1905, which describes an engine having steam generated from the jacket water and delivered to the combustion chamber. It is now stated that the steam so delivered plays an unimportant part merely in the cycle, and is used only to cool the valves, being for that purpose delivered into the valvechest in any suitable manner. Fig. 2 is a section of the combustion chamber, which is made with double walls. Fuel enters at 14 and flows between the double walls, being thus heated, and passing out at k is led to a narrow inlet 15 through a pipe having part of its length coiled, as decribed in the Specification above referred to. At starting, two valves 18,19 are opened to supply air to the combustion chamber and to lead away the products of combustion respectively, the cocks 15, z being partly opened at the same time. The entering fuel is lighted at 6 and thereafter sucks air in through the cock z. The valves 18, 19 are then closed, the same movement opening the cocks 15, z to their full extent. The products then pass to the engine through openings q. Any liquid other than fuel may be caused to circulate in the space between the double walls of the combustion chamber, in which case the fuel pipes do not communicate with that space.

Granted: 1906-09-06
Abstract: 25,410. Brooks, A. A., and Watson, G. A. Dec. 7. Brakes.-Relates principally to hand-operated brakes for railway vehicles, and comprises means for utilizing the friction between the wheel and brake block to increase the brake pressure, for applying the brakes from any corner of a wagon, and for maintaining the brakes applied at different pressures by means of a notched cam and stud. The blocks 1 are hung on pins 5 in slots in suspension links 2. A double bar 6 is pivoted at 7 to one block and connected to the other block by a pin-and-slot arrangement. A lever 10 is fulcrumed on the bar 6, and its free end is connected, by a rod 15, to a link 11 pivoted to the vehicle at 12. A notched cam 20 on a cross-shaft 19 engages a stud 16 on the link 11. This shaft is rocked, by a handle 18, to cause the cam to swing the link 11 outwardly and bring the lever 10 against the brake block at 17 and force the block against the wheel. The fulcrum of the lever 10 then shifts to the point 17, and the other block is forced against its wheel through the bar 6. The blocks are connected to this bar in a line below the wheel centres, so that, when one of the blocks is lifted in its link 2 by its frictional contact with the wheel, the bar 6 turns about the other block and, in the arrangement shown in Fig. 1, wedges the blocks between the wheels, or, in that shown in Fig. 2, tightens the blocks on the same wheel. The cross-shafts 19 at the ends of the vehicle have a handle 18 at each end and are connected by arms 23 and crossed links 24.
