Title: Improvements in Fireproof Construction.
Inventor: FORDYCE ALEXANDER ROBERTS
Filed: 1897-05-18
Granted: 1897-06-26
Abstract: 12,242. Fordyce, A. R. Oct. 20, A.D. 1896, [date claimed under Sec. 103 of Patents &c. Act, A.D. 1883]. Fireproof buildings. - Floors, ceilings, walls, partitions, &c. are constructed of circular or elliptical metal hoops B which are secured together and to columns, beams, or girders A by clips and hangers D, and are embedded in plaster, cement, or the like. A metallic fabric or reticulated plate C may be secured below the girders to form the ceiling. An arched elliptical hoop is produced by stretching a circular conical hoop so as to increase one diameter, and diminish the diameter at rightangles to it. The hoops may have a flat, flanged, or curved shape in cross - section, and may be strengthened by diametral rods or internal hoops. They may be arranged side by side, or to break joint, or one series of hoops connected side by side may be arranged to break joint with a second series.

Patent GB-189723049-A (GB)
Title: Improvements in Machinery for the Manufacture of Wire Netting.
Inventor: BOWER JAMES GARTON
Filed: 1897-10-07
Granted: 1898-09-10
Abstract: 23,049. Bower, J. G. Oct. 7. Wire netting.-Relates to improvements in the machine described in Specification No. 4323, A.D. 1892. The machine is adapted to make wire netting with meshes of different sizes in different parts, and the half pinions which twist the wires are arranged to move in such a way as to join up the parts of different mesh. With this object the slides which move the half pinions to and fro, to engage alternately with corresponding half pinions, are divided into two or more parts, and moved in such a way as to preserve the coincidence of opposite pinions where the join is made between parts of different mesh. In the example shown in Fig. 1, there are four slides A, B, C, D, which produce a netting with a central part of smaller mesh than the rest. When the slide A is moved to the right, the slides B and C are moved an equal distance to the left by the action of levers E, but the slide D moves through a. smaller distance owing to the clearance shown so that the half pinions on one side still coincide with half pinions on the other, as shown in Fig. 2.

Granted: 1898-01-29
Abstract: 24,836. Buxton, S. Oct. 26. Automatic-feed weighers.-A device for cutting off the supply of grain to a weighing-apparatus, when the correct weight has been attained, is shown in Fig. 1, and consists of a contact k<1> fixed to the weigh table j so that, as the table descends, the contact slides on to the insulator k and the circuit is broken. The electromagnet G in consequence releases the weight e of the bell-crank lever E, C, and the gates A are pushed into the closed position thereby. The gates may be brought into the open position again by the hand-operated lever C, or a link M may be arranged as shown, so that, on the removal of the sack or other weighed quantity, the levers are brought back and are kept in place by the electromagnet. In a modified arrangement applied to the hopper of a weighing- machine, a similar arrangement is used, and in addition the platform catch is worked automatically.

Abstract: 26,681. Nunan, J. F. Nov. 15. Air mattresses, beds, and cushions. -A sheet of rubber A, about double the length of the bed &c., is folded and the end s solutioned at A'. The sides are solutioned together except for about two feet at one side, which is left open for the purpose of filling with stuffing-material. The canvas cover B is formed by doubling a long strip of canvas. The ends B are formed into pockets for rods B' with which engage springs E hooking into holes in the end bars C<1>. The sides of the double cover are secured to the sides of the frame by grooves D, D', Fig. 4, and cleats F, F', F<2> and bolts or hooks L. The ends of the cover may be similarly secured to the top of the end bars of the frame, as shown in Fig. 5. The sides of the cover may be secured in slitted tubular end or side bars G of mattress or bedstead frames by forming loops or folds which are put through the slit G<1>, and then a rod G<2> is inserted in the loop and the cover is given a turn round the tube to cause the cover to bend and so make a tight joint. Sleeves with dovetails are then screwed on to the ends of the tubes, and the dovetails engaged with the corner blocks. The tubes are prevented from rotating by set-screws. One of the ends of the cover may have a loop through which passes the end rod or angle-iron of the frame. The cover may be either stuffed with horse-hair, kapok, feathers, flock, &c., or be inflated through a suitable valve. The cover may consist of one thickness of rubbercovered or air-proof fabric the top and bottom sheets of which can have loops on their edges in which are inserted two rods after the loops have been placed in the tubes G through the slots G<1>. Longitudinal supporting-bands may be fixed to the frame to prevent sagging.

The sliding cap is then secured by rotating it, whereby the keys also grip against the inner surface of the cap A, which is made slightly elliptical. The washer E prevents leakage.
Patent GB-189817700-A (GB)
Title: Improved Automatic Gas Igniter.
Inventor: STENDEBACH CARL FRIEDRICH PHIL
Filed: 1898-08-16
Granted: 1898-11-12
Abstract: 17,700. Stendebach, C. F. P. Aug. 16. Lighting gas. - Fig. 1 shows actuating-apparatus for an automatic gas igniter. On open ing the gas cock which leads to the inlet 2, gas flows from this inlet through a slot 7, in the hollow piston-rod 6, and a slot 9 to the channel 10, whence it impinges u p o n a primer 11, which is thereby raised to incandescence and lights the gas, the flame of which heats a metal rod 12. On expanding, this metal rod, acting through a lever 14, lifts the rod 6 so that gas passes through a slot 8 and passage 4 and raises the piston 6<a> so as to allow gas to pass back through the slot 7 to the passage 3 communicating with the burner, incandescent mantle, &c. The burner is now lighted by the flame at the end of the passage 10, which on the further movement of the piston is cut off. When the gas supply is cut off, the piston descends by the action of gravity. 18 is a screw to regulate the speed of motion of the piston, and 17 and 19 are air-ways.

Abstract: 460. Birtwistle, R., [trading as Stott & Co., S. S.]. Jan. 9. Elevators.-For raising and lowering bobbins in shoddy mills, each of the endless chains 2 passes around a pair of sprocket-wheels 3, the lower one of which is adjustable vertically. The bobbins 10 to be raised, are placed upon a table 11 which slopes towards the elevator. As each pair of carriers 9 come round, a bobbin is picked up and deposited on the table 12. Bobbins to be lowered are placed upon a table 25 and automatically picked up in the following way :-A projection 13 in front of the carrier strikes and depresses a lever 14 connected by links 16 and 17 to studs 18, from which depends a segment 19 upon which the bobbin to be lowered rests. At the same time, by means of a link 21 and lever 22 pivoted at 23, a stop 24 is lowered to allow the next bobbin to follow on to the plate 19. Weighted side levers may be employed to prevent the jamming of the flanges.

Title: Improvements in or relating to Accumulators or Secondary Batteries.
Inventor: KLOTH GEORG FRIEDERICH WILHELM

Granted: 1901-06-29
Abstract: 8598. Kloth, G. F. W., B³nning, O. H. G., and Kunhardt, J. G. L. D. April 26. Secondary batteries.-An element of the battery consists essentially of a charged positive plate or charged negative plate, such as is used in an ordinary accumulator, together with an uncharged plate which is electropositive or electronegative relatively to the lead plate, both the said plates being immersed in a solution of sal-ammoniac or common salt, or in acidified water. An ordinary charged positive plate may, for example, be used with an uncharged zinc plate. Fig. 5 shows an arrangement in which a number of charged positives + P<a>, + P<b>, + P<c>, are supported horizontally between a number of uncharged zincs - P<a>, - P<b>, - p<c>, - p<d>, the supporting-ledges on the two poles S<1>, S<2> being alternately conducting and insulating. Fig. 7 shows an arrangement in which the positive active mass M is placed round a core of lead B having top and bottom plates T<1> and T<2>, the zinc being in the form of a surrounding plate V. A charged negative plate may be employed in conjunction with an uncharged relativelyelectronegative plate, e.g., of carbon or manganese peroxide, or a charged positive plate with an uncharged relatively-electronegative plate, e.g., of aluminium. Only a slight effect is obtained by combining a charged negative plate with an uncharged relatively-electropositive plate.
