Title: Improvements in Pneumatic Tools.
Inventor: FITZPATRICK HUGH DONALD
Filed: 1904-12-28
Granted: 1905-02-02
Abstract: 28,519. Fitzpatrick, H. D., [Helwig, A.]. Dec. 28. Percussive hand tools; chisels.-In a pneumatic percussive tool for use as a chisel or hammer, the cylinder 2 is connected to the sleeve 39 by springs 40 so that the sleeve recedes from the end of the cylinder as the tool is removed from the work, and in so doing closes the throttle valve 37. A reciprocating valve 12 is placed concentric with the piston 8 at the back end of the cylinder and projects into the latter by a pin 13, so that the valve will be actuated by the returning piston. The handle 24 is slidably fitted to projections 19, through which air passes, and the portions 23 serve as air cushions, thus preventing a jarring action on the handle. After striking the shank 9, the piston rebounds and opens the port 24, which contains live air, and the air at the back of the piston exhausts through the port 36 and groove 18. At the end of the backward stroke, the valve is driven in, whereby the port 36 is opened to live air and the port 34 to the exhaust. On passing the port 35, the piston admits to the back of the valve air which drives it back to the position shown in Fig. 1.

Title: Improvement in Apparatus for and Process of Electric Welding
Filed: 1905-01-03
Granted: 1905-12-30
Abstract: 1905123. Wise, W. L., [Thomson Electric Welding Co.]. Jan. 3. Making chains.-Chain links, rings, &c. to be electrically welded are formed with Laps 1<c>, Fig. 18, at the junctions, so that the beating gradually extends from the inner to the outer edge of one side of each link as the weld is being closed by the advancing slide 5. The welds may be lap or scarf welds, and a series of threaded links may be passed over two pulleys and alternate links welded up and the burrs reduced by the dies 6, 7, the remaining links being operated upon during the second passage of the chain through the machine and after it has been turned through a right-angle. The weld-closing and work-locating dies 4, 5 are recessed to accommodate the chain and to grip one link during the forging process, one being adjusted by means of a screw 29 and the other limited in motion by a screw 20 and reciprocated by the toggles 17, 18, the toggles 15, 10, and the handlever 9. After the closing of the weld to a predetermined extent, a spring 11 on the toggle 10 engages an adjustable pin 12 and closes the circuit through the controlling-coil 112 of the transformer and through an electro-magnetic circuit-breaker in the welding-current circuit. The treadle 75 is then released and the contacts 101, 102 drawn back by a spring 83 from the work ; then the lever 31 is depressed to raise the die-post 8, by means of the cam 37<a>, and to put the upperforging-die 6 in operation, by means of a pawl 46 on the bracket 42, a pawl 47, and levers and rods 49, 51, 53, 63. The die 6 is reciprocated by a spring and a cam 58 on a shaft 59 fitted with a half-round key 123<a>, Fig. 7<d>, which is partly rotated by the spring 56 so as to lock the driven wheel 122 to the shaft 59 when its tail-end is released by the lever 63. Towards the end of the down-stroke of the lever 31, the pawls 46, 47 trip, and the spring 57<a> returns the lever 63, but the die-post 8 is not raised farther. The die 7, Fig, 14, has link-finishing and link-clearance recesses 7<a>, 7<b> and recesses 7<c> to accommodate the ends of the slides 4, 5, is reversible end for end and, if desired, top for bottom, and is held by a dowel-pin and a clamping- plate 118 in the slotted die-post 8. The contacts 101, 102 are adjustable in angularly-situated grooves in the carriers 91, 92 mounted between roller bearings 103 on the terminal blocks 104<a> of a transformer. The carriers are yieldingly advanced by springs 87, a pressure-equalizing yoke 85, a lever 78, and a treadle 75. The contacts merely touch the side of the work, or may be grooved so as to hold it down. The forging-die may act by pressure instead of impact, or it may be so arranged that the upper die will deliver one or more blows at each depression of the lever 31 and then be thrown out of action. The secondary 104 of the transformer is threaded through the laminated core 106 and is recessed to receive the primary coils 110, 111 and the controlling-coil 112.

Title: Improvements relating to Engines Actuated by Mixed Steam and Carbonic Acid Gas.
Inventor: BRUENLER OSCAR
Filed: 1905-01-23
Granted: 1905-08-24
Abstract: 1267. Br³nler, O., and Kettler, G. Jan. 23. Combustion-product engines.-Relates to producing solid carbonic acid from the gas drawn from the condenser of an engine actuated by mixed steam and carbonic-acid gas. The mixture of steam and carbonic acid gas is produced by burning liquid hydrocarbons in a chamber c, in the presence of water, and oxygen generated by the evaporation of liquid air. The products of combustion after expanding in the cylinder a, enter a condenser. f, from which the carbonic acid is drawn by a pump g and forced into a pipe h leading to the air-supply pipe of a compressor b. The carbonic-acid gas, and air from the compressor, are forced through the coil k<1> and finally through a coil k<2> which passes through chambers containing liquid air, the heat given up to liquid air by the air in the coils causing it to evaporate, the constituents, viz., nitrogen, oxygen, and solid carbonic acid being drawn away from the chambers as required. The liquid air in the three lower chambers is replenished by that issuing from the coil k<2> into the chamber d.

Abstract: 6902. Hamilton, J. April 1. Elastic-fluid turbines. - In turbine - propelled vessels, ordinary turbines on some of several propeller shafts are interconnected with turbines having two rotors. Specification No. 25,714, A.D. 1903, is referred to in connexion with the latter type. In the example shown, four propelling- shafts A', B', C', D', carrying propellers A, B, C, D, are each driven by separate turbines E, F, G, H. The alternate shafts rotate in reverse directions and carry propellers of opposite hands. The outer shafts A', D' are provided with singlerotor turbines and the inner shafts wirh double rotor turbines, one of the rotating members of each of the latter being connected with one of the outer shafts by chain or other gearing L, M. At full speed, steam is used expansively in the turbine E aud the turbine G, whence it passes to the turbine F and the turbine H, and thence to the condensers T. At a reduced speed, steam is only used in the double rotor turbines F, G, which are compounded. The single rotor turbines being in connexion with the condensers T, offer very little resistance. The arrangements may be considerably modified to suit different numbers of shafts.

Title: Improvements in Electric Furnaces.
Inventor: REYNOLDS ALLEYNE
Filed: 1905-04-03
Granted: 1906-03-29
Abstract: 7004. Reynolds, A. April 3. Resistances for heating electric furnaces are enclosed in refractory insulating casings, chemically inert towards the charge and towards the resistance-material. Two layers, each inert towards contiguous substances, may be employed. Siloxicon may form the inner coating, the outer coating consisting, in the case of acid charges, of fireclay or silicate of alumina, preferably free from alkali, and, in the case of basic charges, of magnesite; or siloxicon may be used throughout, oxidation being prevented by the charge, or otherwise guarded against. The resistance-material may be conductive or non-conductive at ordinary temperatures ; in the latter case, a preliminary heating is effected by the charge, or by other means, or the material is mixed or cored with a conductor of the first class. The encased resistance is immersed in the charge or embedded in the furnace walls, and the lower end of the casing may be left open, or closed by a plug made of, or cored with, a conducting material such as graphite, a mixture of graphite and magnesite, or magnesia. Contact with the resistance a is made by an electrode h of carbon, graphite, or water-cooled metal. When the charge is in circuit, the casing b is suspended by means of a collar b<1>and a shoulder e<1> in a sleeve of " morganite " or fireclay, which rests in a ring f. The ring may be electrically connected to the terminal g. Loose carbon, or a moulded mixture of carbon and magnesite, may be used as the resistance-material. The space between the electrode h and the sleeve e is filled with conducting or non-conducting material. A conductive plug l connects the charge with the furnace casing, or. a second encased resistance may be provided. If the cylinder b is of magnesite &c. lined with siloxicon, the sleeve e may be dispensed with. The electrode h may be hollow, so that resistancematerial may be passed in through it to compensate for waste. When the charge is not in the electric circuit, the resistances form part of the vertical or sloping sides of the furnace, and make contact at their lower ends with a ring or block of carbon, while their upper ends project from the top, or through the sides, of the furnace. According to the Provisional Specification, the casing of the resistance may consist entirely of magnesite or of silicate of alumina.

Abstract: 18,489. Heugh, T., Harvey, R., and Clarke, W. A. Sept. 13. Moulding dough.-Dough, after being moulded into shape, is rolled in contact with a smooth surface to form a finer skin. An endless band 2 carries the dough into the mould 8 carried by the cover 7, where it is shaped between upper and lower parts 9, 10, the band 2 and a loose canvas stretch 12 preventing adhesion. One edge of the band being held between a rod 15 and a sloping board 13, Fig. 4, after it leaves the cover 7, the dough shape is rolled between the smooth board 13 and the travelling band. Canvas strips 17 partly rotate the shapes at intervals and, just before the pulley 4, which may taper as shown, a sloping board 18 directs the shapes off the band. In a modification, the cover 7 goes over the whole length of the band, the upper part of which is now always horizontal, and both parts are enclosed by a broad band 25, Fig. 7, passing round pulleys 26, 27 and nipped in near the bottom by rollers 34 so that the band 2 and the two sides 23, 24 form three travelling surfaces between which the dough shapes, retained by a curved guide as they pass round the end pulley, are rolled. The bearings 27<a> of the bottom pulley are adjustable, and a roller 36 prevents the dough from getting into corners. The dough can be fed to the band by a handing-up device consisting of a table 45 overlapping the band 2 and having an endless band 47 passing round it. The dough placed between the band 47 and the outer edge of the sloping projection 46 of the table is brought obliquely across under the band 47.

Title: Improvements in and relating to Paper Cutting Machines.
Inventor: HARDIE JAMES GILBERT
Filed: 1906-03-28
Granted: 1907-03-28
Abstract: 7523. Hardie, J. G. March 28, 1905, [date applied for under Patents Act, 1901]. Cutting-machines for paper.- Relates to paper-cutting machines of the guillotine type, and particularly to the devices for clamping and adjusting the material operated upon. A shaft 15 is driven through spurwheels from a continuouslyrunning shaft 21, a handoperated clutch being employed to complete the gear. The shaft 15 is in elliptic gear with the shaft 10, from which the cutting-bar 5 is reciprocated by suitable connecting-rods. The clutch referred to above is automatically disconnected, and a friction brake operated to stop the shaft 15, at the end of each complete stroke of the cutting- blade. The shaft 15 is also provided with cams 87, adapted to oscillate, through studs 86, a frame pivoted on a rockshaft 70 and comprising side members 81, joined by an end piece 82. The oscillation of this frame is communicated through adjustable hooks 88 to the arms 79 of friction clamps 72, surrounding a friction cylinder 71, secured to the rock-shaft 70. This resultant rotation of the rock-shaft 70 effects, through suitable link-work, a pressure on a clamp 42. The various hooks 88 may each be rendered inoperative so as to reduce to any extent the maximum clamping pressure, and means are described for securing that this pressure is reached by degrees. A sub-clamp 43, having a resilient facing, is provided beneath the clamp 42 to engage the material A operated upon. This clamp is continually pressed upwards through the operation of a spring, and may be depressed by a hand or foot lever, or by the main clamp 42. In operation, the clamp 43 is depressed on to the material A in advance of the knife 6, and is maintained in engagement therewith until the rising cutting-bar 5 engages and lifts a roller 61 on the clamp 42. Gauge brackets 92, having vertical faces 98 pivoted at 97, are provided at the rear of the clamps, and are adapted to be bolted together in the various relative positions necessary for trimming on the different edges of books and pamphlets. The central gauge is secured to a transverse yoke 101, which engages screws at each side of the table, and along which it is traversed by the rotation of the screws through suitable gearing from a handoperated shaft 108 beneath the table.
