Patent GB-189708890-A (GB)
Title: Improvements in or appertaining to a Process for the Production of White, Black, or Coloured Pictures, Writing, or the like, on Glass, Porcelain, Enamel, or Metal.
Inventor: ALBRECHT FRANK
Filed: 1897-04-07
Granted: 1897-08-14
Abstract: 8890. Albrecht, F. April 7. Ornamenting glass, metal, and pottery surfaces.- Gold leaf, powdered metals, and colours not affected by heat are applied to glass, porcelain, enamel, or metal, with neutral or acid silica solutions, such as commercial silicate of soda solution to which precipitated silica is added. The colour may be mixed with the solution, or dusted on after the solution has been painted or stamped on the surface, for the production of pictures, writing, or the like. The articles are afterwards heated to a high temperature. The process is an improvement on those described in Specifications No. 13,838, A.D. 1893, and No. 24,283, A.D. 1895.
Patent GB-189710389-A (GB)
Title: Improvements in Devices for Signalling or Communicating the Action of the Engines from the Engine Room to the Captain's Bridge, or other Place on Board Ship, or for analogous uses.
Inventor: LITTLE ROBERT ROBSON
Filed: 1897-04-26
Granted: 1898-02-26
Abstract: 10,389. Little, R. R. April 26. Signals, indicator or visible, pneumatic, and reply or tell-tale.-Relates to apparatus, such as that described in Specification No. 5495, A.D. 1889, for signalling or communicating the action of a ship's engines &c. to the captain on the bridge &c., and to show whether orders have been properly attended to, the indicating-mechanism consisting of movable objects mounted in glass tubes and operated by air or other fluid pressure from the engines. In the present invention, the movable objects or indicators A are made of cylindrical form, with projecting rings a<2>, which bear against the sides of the glass tubes B. The ends of the tubes B are fitted with rubber or other buffers C, and the ends a of the indicators are made concave, convex, or pointed, &c., to lessen the concussion with the buffers. The indicators may be operated by apparatus such as that described in Specification No. 14,035, A.D. 1889.
Patent GB-189715511-A (GB)
Title: Improvements in Machinery for Rolling Wire, for making Wire Spokes, or for other Analogous purposes.
Inventor: JOHNSON JAMES YATE
Filed: 1897-06-29
Granted: 1897-08-07
Abstract: 15,511. Johnson, J. Y., [Allen, W. G.]. June 29. Rolling.-Relates to machinery for reducing wire, more especially for producing blanks which are reduced for a portion of their length only, such as blanks for wire spokes. The machine is provided with a pair of rolls having several sets of grooves or acting surfaces in the same line for successively acting on the wire, the peripheries of the rolls being cut away between these acting surfaces allowing the wire to be drawn back and rotated ready to be again advanced between the various acting surfaces. The wire x is, by means of the segmental rolls D, fed forward intermittently through the bush d, and a length is cut off by the knife d' operated against the action of a spring d<4> by a cam d<3> and rod d<2>. The cut-off blank is fed forward by a carriage E, actuated by the cam f<2>, into line with a chuck h in front of the rolls A, the wire being clamped on the carriage E by a lever e pivoted at e<1> and operated by a roller e<3> moving over a track e<4>. Inclines at each end of the track engage and disengage the lever e with the wire at each end of the traverse of the carriage E. The shaft i is advanced by the cam k<3> and lever K, and the spring jaws of the chuck are closed on the wire by a conical sleeve h<3> being temporarily held stationary by a spring catch j<3> engaging a notch in the bar j attached to the sleeve h<3>. The wire is advanced by the shaft i and chuck h through a guide l<5> and the recessed part of the rolls against a stop p moved into and out of position by the cam p<3> and lever p<1>. The first pair of acting surfaces of the rolls then operate to give the wire a flat, oblong, or oval section, and when the next recessed part of the rolls come opposite one another, the shaft i and chuck h with the wire are drawn back by the cam k<3>. The shaft i is given a quarter turn, to present the wire edgewise to the rolls, by a rack i<3> engaging the pinion i<2> and actuated by the cam i<4>. To prevent the wire from twisting as it passes through the second pair of acting surfaces of the rolls, which impart a circular section to the wire, a guiding-lever l<2> is pressed against the wire by a projecting portion of a disc m on one of the roll axes. A spring catch h<4> attached to the conical sleeve h<3> engages a tooth o on the frame, so that, when the chuck h is drawn back again, its spring jaws are released, leaving the wire free to be fed completely through the rolls. The rolls may be provided with more than two sets of grooves or acting surfaces, the feeding-mechanism and other parts being modified accordingly.

Title: Improvements in and relating to Upright Pianoforte Action.
Inventor: BECKER FRANCIS LOUIS
Filed: 1897-08-03
Granted: 1897-09-04
Abstract: 18,107. Becker, F. L. Aug. 3. Pianofortes. - R e - lates to actions for upright pianofortes. The damper is actuated in the ordinary way from a lever 8 operated by the key. The jack 10 is pivoted on the lever 8, and has a heel 12 which is acted on by a spring 11, and is also adapted to engage with a fixed adjustable button 15 in order to effect the set-off. The upper end of the jack when the action is at rest, as shown in Fig. 1, lies under a shoulder 21 on the hammer butt, so disposed that the distance between the shoulder and the pivot of the jack is greater than that between the same pivot and the pivot 22 of the hammer. The jack also rests against a convex pad 23 on the hammer butt, and has on its opposite side a smooth metal plate 26, and a surface adapted to engage with a projection 24 on the hammer check 18, which is adapted to engage with a check 13 on the lever 8 after the hammer has struck the string. This position is shown in Fig. 2 when the set-off has just been effected, the projection 24 being in contact with the plate 26 and the surface 25. The position for repetition, obtained by slightly releasing the key, appears from Fig. 3 The spring 11 forces the jack into the positior shown, its end just coming under the shoulder 21 while the hammer is held in place by the pad 23 and the plate 26. The hammer butt may be acted upon by a spring 19 attached to a fixed rail 5, bu this can be dispensed with.

The minute-hand of the clock H carries a cam D, which completes, between the lever L and contact V, the circuit of the electromagnet B every quarter of an hour &c. This magnet, when energized, acts through the armature b<1> and pawl k to rotate the arm M from one contact t<1> to the next of the forty-eight contacts on the switch C. The contacts t<1> are connected to hooks E, above each of which is a time mark I corresponding to the particular contact. The hooks E are adapted to receive numbered contact-pieces F, which are connected to the wires from the bells S in the rooms of which the numbers correspond to those on the contact -pieces. The aperture f in each piece F is made tapered, to ensure a better contact with the hooks. In use, the piece F corresponding to the room in which the person is to be called &c. is hung on the hook E corresponding to the time at which he is to be called. At the desired time, the arm M touches the proper contact t', and so completes the circuit of the corresponding bell S. The arrangement shown on the right of the Figure is adapted automatically to ring up the attendant at predetermined times, and to inform him of the rooms in which persons are to be called &c. The numbered contact-pieces F<1> each have two apertures f<1>, and are hung on the two hooks E', E<2>, which are connected to the switch C and call bell S<1>, so that the bell is rung at the time or times determined by the contact-pieces on the hooks, the contact-pieces also indicating the rooms to be called &c.

When the carbide in that chamber is exhausted, the water overflows by a communication j to the lower part of the next chamber, and so on. The generated gas passes likewise through these communications, and finally leaves the last chamber by a tube k provided with a well k<1> for condensed water, and immersed in the water in the upper compartment c. An outlet tube k<3> is provided to the last compartment but one, so that either the last compartment can be in use by itself while the others are being recharged, or it may be cut out for recharging while the others are in use. Each chamber has a water gauge m.
