Claims.—(1.) Pruning-knives having rebated lever-handles, as A1, B1, with blades, as A, B, having their outer faces bevelled and their inner faces on a plane, and arranged to cut equally towards one another, means for maintaining a constant pressure of the blades against one another, substantially as set forth. (2.)

No. 11679.—6th June, 1899.—THE “NEILD” SLEEVE ELECTRIC JOINT SYNDICATE, LIMITED, of Bloomfield House, London Wall, London, England, Manufacturers (assignees of Harry William Neild, of 89, Blackheath Road, Kent, England, Engineer). Improved joint for telegraph and other wires conveying electricity.

Claims.—(1.) A sleeve open at one side for part of its length, and coated internally with solder. (2.) The combination of a sleeve open at one side for part of its length, two conductors lying side by side in the sleeve, and solder filling the interstices between the conductors and the sleeve. (3.) The combination of a sleeve open at one side for part of its length, two conductors lying side by side in the sleeve, their ends protruding beyond the sleeve, and being bent at an angle to their length, and solder filling the interstices between the conductors and the sleeve. (4.) Joints for electric conductors substantially as described, and illustrated in the drawings.

No. 11680.—6th June, 1899.—HORACE LENOARD SHORT, of New Maiden, Surrey, England, Consulting Mechanical Engineer. Improvements in methods of and apparatus for increasing the volume of sounds from telephonic or phonographic instruments, and transmitting such sounds to distances.

Claims.—(1.) The reproduction upon a magnified scale of sounds, articulate, musical, or of any kind (obtained in the usual way in the first place by the vibration, by means of such sounds, of the diaphragms of telephones, telephonic instruments, or the like), by causing vibrations produced by such sounds to produce corresponding synchronous undulations in a column of air, steam, gas, or vapour, which consequently gives forth through a trumpet-shaped or other distributing mouthpiece sounds identical with the originating sounds, but very much magnified or increased in volume and power. (2.) In the reproduction upon a magnified scale of sounds, articulate, musical, or of any kind, as claimed in claim 1, the recording of such magnified sounds upon the cylinders or discs of phonographic apparatus, from which they can be reproduced whenever desired. (3.) In the reproduction upon a magnified scale of sounds, articulate, musical, or of any kind, as described and claimed in claim 1, the method of further magnifying such sounds by using them to cause the corresponding vibration of additional diaphragms, the vibrations of which are used to reproduce corresponding sounds still more magnified. (4.) For the purpose of reproducing upon a magnified scale sounds, articulate, musical, or of any kind, the apparatus consisting of a receiving telephonic diaphragm g, chamber a, cylinder b, cylindrical valve c having a flange c¹, larger cylinder d, valve e, openings c³ and f, cap l, spring m, opening n, chamber o, inlet-passage a¹ and outlet-passage p, substantially as described, and illustrated in Fig. 1 of the drawing. (5.) In apparatus of the kind described in claim 4 and illustrated in Fig. 1, the use, instead of the vibrating telephonic diaphragm g, of a phonographic cylinder having the sounds to be reproduced in a magnified form recorded by depressions upon its surface, such depressions operating the valve c when the cylinder is revolved at the proper speed, substantially as described. (6.) In apparatus of the kind described and claimed in claim 4, in combination with the diaphragm g, chamber a, cylinder b, cylindrical valve c having a flange c¹, larger cylinder d, valve e, openings c³ and f, cap l, springs m, and openings n, the spindle r, operated by the valve e, and causing a cutting point or tool s to cut helically upon a revolving phonographic cylinder t deep depressions corresponding with the vibrations of the sound-operated diaphragm g, and capable of reproducing such sounds upon a magnified scale by means of a suitable phonographic diaphragm, substantially as described, and illustrated in Fig. 2 of the drawings. (7.) In apparatus of the kind described in claim 6, the use, instead of the vibrating telephonic diaphragm g, of a phonographic cylinder having the sounds to be reproduced in a magnified form recorded by depressions upon its surface, such depressions operating the valve c when the cylinder is revolved at the proper speed, substantially as described. (8.) In apparatus of the kind described and claimed in claim 1, the modification consisting of a mouthpiece u, the telephonic diaphragm g, chamber a, cylinder b, valve c, larger valve e, spindle r, cap l, and escape-passage p for a column of air, steam, gas, or vapour forced in through the inlet-passage a¹, in which column undulations are produced by the movements of the valve c, the sounds being reproduced in a greatly magnified form by such column passing from d to a distributing trumpet-shaped opening, whilst the spindle r attached to the valve e may be used either (1) for transmitting the movements of the valve to a second diaphragm of a kind similar to g, which operates a second valve similar to valve c, by which means undulations are caused in a second more powerful column of air, steam, gas, or vapour, and the sounds are still further magnified, or (2) for actuating a cutting-instrument by which records are cut upon a revolving phonographic cylinder in the manner illustrated in Fig. 7, substantially as described and illustrated. (9.) For the purpose of reproducing and largely magnifying the sounds, articulate by means of the human voice, musical, or of any kind, produced in the diaphragm of a receiving telephonic instrument, the combination of the mouthpiece u, the vibrating diaphragm g, chamber a, inlet-passage a¹ through which air, steam, gas, or vapour is forced, partition x having parallel openings through it, valve y consisting of tongues fitting such openings, spindle v connecting the valve y with the diaphragm g, cap w, spring m, and sound-delivery opening z, substantially as and for the purpose described, and illustrated in Figs. 8, 9, 10, 11, and 12 of the drawings. (10.) In the apparatus described and claimed in claim 9, and illustrated in Fig. 8, the substitution for the mouthpiece u and diaphragm g of the cutting-instrument M operated by a phonographic cylinder N, upon which the sounds to be reproduced in a magnified form have formed or cut depressions helically round the cylinder by means of a
