Patent GB-190417365-A (GB)
Title: Improvements in or relating to Alarm Operating Mechanisms.
Inventor: BOULT ALFRED JULIUS
Filed: 1904-08-09
Granted: 1904-12-22
Abstract: 17,365. Boult, A. J., [Eastern Fire Protection Co.]. Aug. 9. Signals, automatic-alarm.-Relates to means for operating alarms such as are used in connection with sprinkler systems for fire-extinguishing, and consists in the arrangement of valves in the alarm system, and in the provision of a water relay. As shown applied to a sprinkler system, the ordinary flap valve 5, which is raised when a sprinkler operates, has an extension 11, through which passes the spindle of a valve 9. A nut 13 is adjusted on this spindle in such a position that the valve 5 does not contact with it when water-hammer or leakage takes place. When, however, a sprinkler operates, the valve 9 is lifted, and water passes through the pipe 17 to the chamber 18, where it accumulates on the diaphragm 21 and finally depresses it. The valve 19 is thus pushed from its seat, and water enters the bottom of the chamber through a pipe 23, from the ordinary supply or other convenient source, and passes through perforations 26 and down a pipe 24 to the alarm. To get a time-lag in the operation of the valves 9, 19, a casing 30 may be provided in the pipe 17 with a plate 29 across it having a small central hole 28 for the water to pass through. A strainer 31 may be provided, and there is an open drip pipe 32 to empty the chamber 18 and to prevent water from passing by leakage through the casing. The water entering the chamber to actuate the alarm would normally press against the diaphragm 21 and, equalizing the pressure, raise the valve 19 again ; a plate 23 is provided to prevent this. The central hole 34 in this plate, through which the spindle 20 passes, is closed by the hub 35 of the diaphragm when this descends, and any water that may have passed through runs off down the pipe 37. In the modified chamber 18<1>, shown in Fig. 2, the diaphragm is continually under the pressure of the alarm supply and is therefore strengthened by a web 39. When sufficient water has entered the chamber through the pipe 17, the upward pressure on the diaphragm due to the supply through the pipe 23<1>, which has kept the valve 19<1> from being forced open, is counterbalanced, and the valve is depressed. The alarm pipe 24<1> proceeds from the lower part of the casing. Fig. 2 also shows the spindle perforated at 38 to aid the draining of the chamber.

Title: Improvements in, or relating to, Sliding Doors.
Inventor: MARKS GEORGE CROYDON
Filed: 1904-08-22
Granted: 1904-10-13
Abstract: 18,182. Marks, G. C., [Bitner Car Equipment Co.]. Aug. 22. Doors, wagon.-Relates principally to means for fastening sliding doors for railway wagons &c. which fit between pairs of projecting strips, such as the strip 3, Fig. 1. Hangers 12 run on a track 4, which is secured to distance-pieces 5 and has terminal stops, Fig. 14, against which the hangers abut. The hangers are connected to the door by hooks 17 at the ends of cranks 16 on a rod 15<a>. The rod 15<a> is connected by a crank arm 48, rod 64, and crank arm 52 by a similar rod 18. The crank arm 52 has an extension 61 which carries a sliding bolt 62 with a projection on its end to engage with a recess 44, Fig. 3, in a piece 42. The bolt 62 has a strengthening-projection 63 which slides in a longitudinal slot in the extension 61. To unfasten the door, the extension 61 is pressed back, to allow the sliding bolt 62 to be raised, and is then pulled forwards so that the rod 18 turns in the bearings 24. As the rod 18 turns, its curved ends 19, which engage with the socket-pieces 20, force the lower part of the door outwards. When the pin 51 of the crank arm 48 reaches the bottom of the eye 65 in the rod 64, the rod 15<a> is turned, and the cranked ends 16 cause the upper part of the door to swing slightly outwards to assist the disengagement of the curved pieces 19 and to allow the door to be moved over the projecting strips 3. After release, the door may be swung outwards by hand to clear the pieces 20. To hold the door in its open position and to make it lie flat against the side of the wagon, one piece 19 may be turned into one of the socket-pieces 20, an additional socketpiece 20<a> being provided if necessary. To prevent unauthorized opening of the door, a seal wire, padlock, &c. may be passed through the hole 46, Fig. 3, in the piece 42. The outer bearings 24 and also the inner bearings, Fig. 3, of the rods 15<a>, 18 are so arranged that they may be made in one piece and yet be placed on the rods after the cranks at their ends have been formed. Fig. 9 shows how the bearings 24 may be formed with projections 31 to allow each bearing to be secured by one bolt only. The hooks 17, Fig. 2, allow the entire door to be disconnected.

Patent GB-190422822-A (GB)
Title: Improvements in and relating to Alternating Current Electric Motors.
Filed: 1904-10-22
Granted: 1905-08-24
Abstract: 22,822. British Thomson-Houston Co., [General Electric Co.]. Oct. 22. Motors, alternating-current; motors, controlling.- A synchronous motor has a field structure with projecting poles of a pitch unequal to that of the poles produced by the armature, so that at any instant some of the field poles are ahead of the corresponding armature poles and others are behind, these two portions being connected separately to serve as a shortcircuited two-phase winding at starting and being connected to a source of direct current when the motor reaches synchronism. Reference is made to Specification No. 8403, A.D. 1904. The distributed slotted armature, Fig. 1, is connected to produce eighteen poles N, S, while the field structure F has sixteen polar projections, two of which are left blank. When the upper field pole n is directly below the armature pole N, the fourth field pole on either side is half way between two armature poles. These two poles, one on each side, are left blank, and the usual winding is continued on the remaining poles, with the result that the lower half of the field has its coils wound in an order contrary to the normal order. The resultant voltages induced in the armature when summed for each pole give a resultant approximately sinusoidal, so that the motor will operate as an ordinary synchronous motor, but will be without the usual tendency to lock at starting. If the number of poles is odd, instead of leaving two diametrically-opposite poles blank, two adjacent polar projections are wound. for the same polarity as shown in Fig. 2, in which there are twelve armature poles and fourteen field poles, or the number of armature poles may be greater or less by any multiple of two than the number of field poles. The speed of the motor may be controlled as described in Specification No. 25,858, A.D. 1903. The poles may be divided into two groups as described, and, by suitably connecting, the field winding may be caused to act as a polyphase winding at starting. The connections are shown in Fig. 3, in which three points on the field winding are connected to slip-rings, the brushes of which are connected to the rheostat. The brushes may in addition be short-circuited by resistances d as shown in Fig. 4. The exciter E is connected to the movable member of the rheostat, which is also connected through a resistance r and a switch s to the brush b. After the motor has been started, either by means of the resistances d, d or of the rheostat, the resistance is cut out, the field of the motor is excited, and, when synchronism is reached, the switch s is opened.

Title: Improvements in Machines for Doubling and Twisting Yarns or Threads of Fibrous Substances.
Inventor: STELL ALFRED
Filed: 1905-08-01
Granted: 1906-04-12
Abstract: 15,705. Stell, A. Aug. 1. Stop-motions.-In doubling and twisting machines having vertical draw drums, a stop-motion is provided by which on breakage, failure, or slackening of any of the single threads, or the doubled thread, the draw drum and the spindle band are arrested simultaneously. The mechanism comprises four levers f, g, h, k pivoted to a fixed bracket m on a stationary rail. The single threads from the creel pass through and support separate detector eyes n carried by the lever k, and are then directed round the draw drum a, beyond which they pass together through an eye in a pivoted lever b to be doubled and twisted on the bobbin e. The lever k normally engages a notch in the lever h, and the lever b is horizontal. When any single thread breaks, fails, or slackens, the corresponding wire n falls and is acted upon by a wiper p to disengage the lever k from the lever h, which then falls by gravity, depressing, through the lever f, the lever b into the path of the ratchet coupling of the drum a, and at the same time acting through the rod q<1> to move the driving- band r on to a smaller part of the driving-pulley t and grip it against a bar r<1>. Breakage of the double thread allows the lever b to tilt and through the lever f withdraw the lever g, which normally supports another drop wire u on the lever k, the wiper then acting as before to stop the parts.

Patent GB-190522616-A (GB)
Title: An Improved Electrical Circuit Closing Device Operated by the Depression of the Rail on Railways or Tramways
Inventor: DINEEN JOHN FRANCIS
Filed: 1905-11-04
Granted: 1906-11-01
Abstract: 22,616. Dineen, J. F. Nov. 4. Contacts, electric.-A contact device for railways, operated by the depression of the rail, is fixed on a wooden block or other support K, Fig. 1, placed at a short distance below the rail J, one flange of which engages short horizontal levers A, frictionally clutched to a long contact-making lever A' on the same spindle C. The necessary friction is produced by the pressure of springs E, Fig. 3. When the arm A' is raised, the two electrical terminal springs G, G', Fig. 2, are bridged by an insulated contact piece a', and after a short distance the further upward movement of the arm is checked by an adjustable stop F. An abnormal weight on the rail drives the support K into the ballast and depresses the short levers farther without interfering with the contact-lever, or with its subsequent working. When the rail rises to its original position, the contact-lever immediately falls, and in the abnormal case the support is raised out of the ballast by hooks L, L<1> which catch over the rail flanges. The wires leading to the signal box may be contained in the pipe shown. In a modified form, the short and long arms of the lever are made in one piece, and the upper stop F is removed. The support may be a reversed rail placed crossways. In another modified form, applicable to bridges or elsewhere where the depth of ballast is not great, the supporting-block fits like a tight piston in a rigidly fixed case, into which it is forced by abnormal loads.
