Title: Improvements relating to Gas Burners.
Inventor: HUMPHREYS ALEXANDER CROMBIE
Filed: 1900-07-07
Granted: 1900-10-13
Abstract: 12,333. Humphreys, A. C., and Glasgow, A. G., [Gibbs, W. E.]. July 7. Incandescent gas lamps.-The heat of the flame is increased by thoroughly mixing and heating the gas and air supplies before ignition. The bunsen tube B is heated by conduction from a plug C, which closes its upper end and causes the mixture of air and gas to escape through the lateral perforations B<4> into a hood E. This hood is closed at its upper end E', which is so supported from the plug U as to be in contact with the flame, and it is vertically grooved on its outer side to present a large heating-surface to the mixture of air and gas ascending between it and the surrounding casing D. In consequence of there being no metallic contact between the hood E and the casing D, there is no loss of heat from the hood by conduction, and, by adjusting the hood and the casing relatively to each other, the shape of the flame may be varied. The mantle rod H is supported from a socket D<3> on the casing D. In a modification, the conical plug C is replaced by a flat-topped plug provided with a grooved flange, and the hood is formed by a series of rods arranged around a flanged nut, which screws upon the tube B. In other modifications, the plug C and the perforated portion B<3> of the burner are dispensed with, the open upper end of the tube B discharging into a hood which is formed with an unperforated top, and screws either upon the tube B or upon an upturned flange on the casing D.

Title: Improvements in Machines for Grinding Cutters, Shafts, Arbors, and the like.
Inventor: GUEST JAMES JOHN
Filed: 1900-09-06
Granted: 1901-06-15
Abstract: 15,854. Guest, J. J. Sept. 6. Sharpening ; surfacing and polishing enlarging holes.-The apparatus is for grinding cutters, shafts, arbors, taper sockets, &c., and also for grinding holes. The work, such as a cutter P, is held between headstocks k, l, which slide upon the horizontal table h. This table swivels upon the slide g, which slides on the saddle f adjustable on the vertically-adjustable knee b. The upper part of the headstock k pivots on the lower part, the pivot pin k<4>, like the pin h<1> of the table h, being vertical. A hooked piece n<1>, fixed to a horizontal slide n<2>, bears on the tooth being sharpened at a point in the same horizontal plane as the centre line of the headstocks k, l. By this means cutters of various sizes and angles can be ground with correct and uniform clearance without special adjustment in each case. The grinding-wheel e is fixed to a spindle, the axis of which is inclined to the plane just mentioned and makes an angle with the normal to the table h which is the complement to the angle of clearance being cut on the work. The headstock c carrying the spindle turns on a pivot a<2> at right-angles to the spindle. The headstock c carries a small grinding-wheel m on an arm m<3>. This is for grinding holes. The axis X, Y of the pivot a' touches the pulley d', so that the driving-belt does not leave the pulleys r, q, or d' as the headstock is turned upon this pivot. Overlapping shields s, s<1> sliding in contact with one another are carried by the headstocks k, l to prevent emery powder, water, &c. from falling upon the table. The Provisional Specification states that the cutter holder, provided with the usual V groove, may swivel only on a vertical axis, and that a fine or a rapid adjustment of the table h may be effected by a half-nut which may be thrown out of gear with the adjusting-screw by a lever.

Granted: 1902-07-03
Abstract: 9857. Boult, A. J., [Sholes Typewriter Manufacturing Co., C. L.]. April 29. Type-writers. - Relates to the "actions" of front-strike machines. Fig. 1 shows the machine in sectional elevation from front to rear, and Fig. 2 shows a vertical crosssection viewed from the rear, the plane of section of the right-band half of the Figure being nearer the keyboard than that of the left-hand portion. The type-bars A are disposed in two banks, with their type-arm portions a' arranged in two vertical planes close to the plane of the impression point, and their pivot arms a extending outwards to right and left. Fig. 2 shows a portion of the right hand bank only. The pivot arms are supported in bearings B, and are capable of turning and moving endwise in their bearings. To bring a type to the impression point, the pivot arm a of the bar which carries it must first be shifted to bring the type-arm a' into the plane of the impression point, and must then be turned to produce the impression. From each pivot arm a extend two pins c, d, Fig. 1. The pin c enters an L-shaped slot c' in the coverplate C, and the pin d enters an inclined slot d' in a verticallymovable slide D. The slides D are arranged in three different planes, to afford room for overlapping. Shouldered turn-buttons F pass through slots f in the slides D, and serve to guide them. A slotted bar G guides the lower ends of the slides. When a keylever H is depressed, the auxiliary lever J is drawn down by the link j and the corresponding slide D is depressed. During the first part of the movement of the slide, the cam-like action of the slot d<1> on the pin d causes the pivot arm a to move endwise until the pin c reaches the end of the hoiizontal portion of the slot c<1>. Further depression of the slide draws down the pin d and rocks the arm a so as to produce the impression. The slots d<1> are inclined in opposite directions on the two sides of the machine.

The end of the key under the cutter is higher than the other end of the key, in order to counteract the tendency of the cutter to lower the end of the key, and so not to cut vertically.
Patent GB-190304062-A (GB)
Title: Improvements in or in connection with Ventilating Apparatus for Water Closets and Urinals
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1903-02-20
Granted: 1903-07-30
Abstract: 4062. Thompson, W. P., [Schultz, C. W., and Walker, C. M.]. Feb. 20. Ventilating closets; urinals.-The pan is ventilated by the action of a water-jet aspirator, the valve of which is opened either by hand or by seat-action and closed automatically by a spring controlled by a dash-pot. Fig. 5 shows one form of the apparatus. Water is admitted by the valve 20 into a pipe 9 opening into an annular chamber 7 contained in a pipe 5, which is connected to the closet pan at one end and opens into a ventilating- pipe 10 at the other. The chamber 7 is closed towards the pan but is perforated with holes 8 towards the pipe 10, so that, when the water issues through these holes, an aspirating action is set up in the pipe 5: A perforated inclined plate is arranged at the bend where the pipes 5, 10 join, so that the water is separated from the air and runs back into the pan through the passage 11. The valve 20 is carried by a bent rod which passes through a flexible collar 18 and terminates in a projection 17, which takes into a slot 16 in a stem 12. This stem carries a piston 14 which works in the cylinder 13<a> and is urged upwards by the spring 15, its speed being controlled by a timehole in the cover 22. The stem is either depressed by hand or by the seat when it is occupied. This action opens the valve 20, which remains open, until the lower end of the slot 16 bears against the projection 17. At this time, a hole 23 in the stem, which is hollow for a short distance, passes beyond the cover 22 and gives exit to the air contained in the cylinder 13<a>, so that the valve is closed with a sharp uncushioned motion of the stem 12. Various modifications may be made in the valve gear. Thus, the bent rod may have a double bend and be moved in one direction by a collar on the stem 12 outside the cylinder 13<a> and in the other by a pin upon it dropping into a hole in the stem. Or a straight rod telescoping in a tubular portion of the stem 12 may act directly upon the valve ; or the valve may be mounted on an extension of the stem working in an elongated chamber provided with a valve seat; or a plug cock may be turned by the action of a lever which works in a slot in the stem 12. Fig. 10 shows a modified apparatus, in which water is admitted to the annular chamber 83 provided with jet openings 84 through a tube 72 which crosses the air-withdrawing tube 85. The water is controlled by the valve 91, which is checked in closing by the dash-pot piston 76 and is opened by the action of the bracket 88 on the seat. The piston carries a badly-fitting valve 80, or has a time opening or the like.
