Title: Improvements in Electric Switches.
Inventor: CARRIGAN HENRY JAMES
Filed: 1909-10-20
Granted: 1910-07-14
Abstract: 24,109. Carrigan, H. J. Oct. 20. Switches.-In a combination electric switch, particularly applicable for controlling the ignition circuits in automobiles or motor boats, a baffleplate is used for disengaging one of the movable contacts from a fixed contact when the movable contact and baffle are moved relatively from a given position. The switch comprises two concentric rows of fixed contacts, one contact in each row being connected to opposite sides of the circuit, and two contact-arms in electric connexion, each of which is adapted to engage the fixed contacts in one of the rows, in such a manner that the circuit can only be closed when the proper contacts are in engagement. Each of the fixed contacts is made from a single piece of sheet metal, and comprises a flat contact-plate 10 provided with a locking projection 11, a wiring-lug 14, and fastening-lugs 12, 13, which are passed through openings in the base. The movable contact-arms 25, 26 are provided with contact fingers 28 having locking-recesses adapted to engage with the projections 11. The outer contact-arm 26 is mounted with its hub 27 on a tubular shaft 30, which is mounted in the front wall of the casing and turned by means of a finger-disk 32. The inner contact-arm 25 is mounted on a tubular shaft 33 provided with a finger-disk 34. The contact-arms are coupled to the shafts in such a manner that they are compelled to move forwards with the shafts, which can be turned backwards independently of the contact-arms. Two baffle-disks 38, 39, provided with notches 42, are employed to hold one of the contact-arms out of engagement with the fixed contacts. The smaller disk 38 is secured to the inner end of the shaft 33, the larger disk being secured to a central shaft 390 provided with a finger-disk 41. The notch of the disk 38 is in line with the contact-arm 25 when this is coupled to its shaft, but the contact-arm is unable to engage the contacts until the finger-disk 41 has been turned to bring the notch in the baffle-disk 39 into the proper position. The finger-disks are provided with numbers &c. to indicate the proper combination for closing the switch. Means are provided for giving an alarm when an attempt to close the circuit is made by an unauthorized person, one or more of the contacts in each row being connected to a battery and an alarm bell 45.

Title: Improvements in Pneumatic Percussive Tools.
Inventor: HUGHES JOHN HUDSON
IPC: B25D9/14
Filed: 1910-03-05
Granted: 1911-03-06
Abstract: 5593. Hughes, J. R. March 5. Percussive hand tools. -In percussive tools of the type having a compound hammer - piston, the inner piston is made longer than the outer piston and at the rearward end of the stroke, projects beyond the forward end of the outer piston. When the valve 4 is depressed by the trigger 8, pressure-fluid passes from the inlet 3 through the annular passage 9, the ports 10, the annular passage 11, the ports 12 and the passage 14 to the ports 20, 21. In the position shown, the fluid then passes through grooves 24, 25 and the ports 26, 27, 44, 44<a> to the rear cylinder space and the hammer pistons 22, 23 move forward, the exhaust passing through a passage 40 and a port 41 in the inner hammer 22 and a port in the outer hammer 23 to a groove 28 in the hammer 23 and exhaust ports 45<a>, 46. The inner hammer first strikes the tool-holder 16 and the outer hammer then moves on and strikes a second blow, also opening the rear cylinder space to exhaust through the port 46. Fluid then flows through the ports 26, 27, 43, 40 to the front cylinder space and the hammers move backwards, first closing the exhaust port 46 and then resuming their initial position by contact with a member 19 resiliently held by pressure fluid acting behind it. The hammer 23 is held against rotation by a pin engaging the groove 28. A port 42 and groove 38 in the inner hammer 22 allow lubricant to pass between the hammers. The inner piston may be prolonged to give expansive working, and is held in place by a screwed sleeve 35, pins 36, and a spring 37<a>. Specification 8550/00, [Class 61, Hand Tools &c.], is referred to.

IPC: F23J15/02
Filed: 1910-04-09
Granted: 1910-08-18
Abstract: 8635. Engelhardt, Rudolf, Baron von. April 9. Spark arresters and extinguishers.-A sparkarrester of the kind wherein the sparks are deflected into a water-trough is fitted with a movable trough, which rises when the water is nearly evaporated and closes the flue. Fig. 1 shows an apparatus wherein a movable watertrough 6, fitted in an enlargement chamber 2 of the chimney, surrounds the flue 1, and is counterweighted by a weight 10 which encircles the chamber 2, so that when the water evaporates, the trough rises until the deflecting-hood 5 reaches the roof of the chamber 2 and closes the outlet 3. In a modification, the deflector 5 is attached to the blast-pipe 4, and the stays 7 are omitted, so that when the trough 6 rises, it engages with the lower edge of the deflector 5. The position of the weight serves to indicate the condition of the water-trough.
Patent GB-191008753-A (GB)
Title: Improvements in or relating to Upsetting Machines for Heading Nails and other Articles.
Inventor: BOULT ALFRED JULIUS
IPC: B21G3/26
Filed: 1910-04-11
Granted: 1911-04-11
Abstract: 8753. Boult, A. J., [Ward Nail Co.]. April 11. Fluid-actuated gears. - In a machine, actuated by fluidpressure, f o r heading nails, spikes, tacks, rivets, bolts, &c., the heading means, the feeding of the stock, the operation of the holding-dies, and the cutting - off mechanism are actuated by fluidpressure cylinders with valve means for utilizing the exhaust from one cylinder to control the time of operation of another cylinder. The stock is cut off by tools 33 operated by pistons 37 in two opposite cylinders 38. Fluid enters by the port 52, Fig. 3, to drive the two valves 45, 46 to the ends of the valve-chest, thereby closing the exhaust 44 and opening the cylinder to the inlet port 43 by way of port 42. The piston 37 is thus driven out to operate the cutting-off tools 33. When the piston uncovers the port 48, fluid enters behind the valve 45 to move it over the inlet port 43, the remainder of the stroke being effected by expansion. The port 48 is throttled by a screw 49 to vary the time of cut-off and so vary the blow. When the port 50 is uncovered, the valve 46 is returned, and the rear of the cylinder is opened to exhaust through the ports 41, 44. The pistons are returned by springs, and cavities 37<a> for cushioning are provided. Exhaust from the ends of the valve is accomplished by providing the valves with extensions 47 passing loosely through holes 96 in the valve box caps, but to prevent escape when the valves are in their forward position, washers 97 on the stem engage recesses in the cap. Similar valves are applied to each end of the heading-cylinder.

Title: Improvements in Signalling on Single Line Railways or Tramways.
IPC: B61L23/12
Filed: 1910-10-18
Granted: 1911-03-02
Abstract: 24,158. Siemens Bros. & Co., and Ferreira, L. de M. G. Oct. 18. Electrical systems, automatic and non-automatic; single-track systems.-Relates to turnout systems having at each end of each turn out two signals which normally indicate " line " clear," and are changed to indicate " leave to " proceed " when a train is about to pass on to the single line, but which, when trains arrive simultaneously at both ends, indicate this to both drivers, and consists in an improved arrangement of working. Normally-lighted red and green lamps a<5>, a<6> and b<5>, b<6> are provided at the ends of the turn-outs. When a train, in passing from W on to the single line, operates a contact g<5>, the magnet f<5> is energized and lifts its armature e<5> to break the circuit of lamps a<5>, b<0> and the magnet c<6>, which drops its armature d<6>, thus keeping the circuit broken until the train passes contact h<6>, whereupon the circuit is remade through the magnet c<6>, which picks up its armature and thus maintains the closure; similar action takes place when a train passes in the other direction. When two trains arrive simultaneously, all the lamps are put out, and to allow one train to proceed, a switch j<1> in circuit with a resistance k<1> is provided at one end only. The driver at this end opens and closes this switch several times, causing the lamps b<5>, a<6> to glow intermittently, giving leave to the other train to proceed. Alternatively, the contacts g<5>, h<6> may be omitted and the armatures e<5>, d<6> replaced by hand-operated switches. In this case, the switch j' is unnecessary. Again, the lamps may be arranged in normally-open circuit, the lighting of a green lamp at the same end giving permission to a driver to proceed, while both lamps glowing show the presence of two trains.
Patent GB-191024916-A (GB)
Title: Improvements in and relating to Variable Electric Air Condensers.
Inventor: SOBOTKA BERNHARD FRIEDRICH
Filed: 1910-10-27
Granted: 1911-09-14
Abstract: 24,916. Sobotka, B. F. Oct. 27. Condensers. - An adjustable electric c o ndenser having air as dielectric has a number o f relatively movable pairs of sets of plates, and means for putting these pairs of sets into parallel or series a t will, so as to obtain capacities respectively greater and less than the capacity of one pair of sets, and variable from zero to a maximum. The movable sets are secured to, but are insulated from, a common axis. The insulating- material joining the plates is arranged so as to leave only air between them. In a condenser having two pairs of sets of plates, these are semicircular in shape. The fixed plates 5 are threaded on rods 29 arranged between two metal plates 1, 9, from which they are insulated, metal distance-pieces 6 being placed between them. The insulating cover-plate 10 is supported by the plate 9. Each set of movable plates 11 is supported by two metal rods 12 in a similar manner, the rods being secured to, but insulated from, disks 13, 14. The lower disk is seated upon a pin in the metal plate 1, and the other has a rod 16 carrying an arm 17 secured to it. The rod 16 has a bearing in the cover-plate 10. Narrow rings 40 of insulating-material may be disposed between the fixed and movable plates. The arm 17 is designed to limit the movement of the plates 11 by contact with stops 21 fixed to the plate 9. To enable the capacity of the condenser to be varied from zero to a maximum by varying the relative positions of the fixed and movable plates, a head 18 and a pointer are secured to the rod 16. A scale is provided on the cover-plate, upon which are also terminals 22 and a plug socket 23 adapted to receive a plug 24. The fixed sets of plates 27, 28, Fig. 6, are each connected to a terminal 22. One set 30 of movable plates is permanently connected by a flexible conductor 31 to one set 27 of fixed plates, and the other set 29 of movable plates and the remaining set 28 of fixed plates are respectively connected to the two parts of the concentric socket 23 so that they may be connected together if desired by the plug 24. As shown, only one pair of sets of plates 28, 30 is in use when the plug is removed from the socket, the plug coupling the remaining pair 27, 29 in parallel with these. More than two pairs of sets of plates may be used, suitable plugs and sockets being also furnished. It is then possible to couple pairs of sets in parallel or series connexion in addition to using a single pair alone. Figs. 7, 8, and 9 show diagrammatically three pairs of sets of plates connected so as to give the capacity of one set, two sets in series, and two sets in parallel respectively. Greater variations may be obtained with increased numbers of pairs of plates.
