Title: Improvements in Apparatus for Storing and Reproducing Audible Messages and Signals.
Inventor: POULSEN VALDEMAR
Filed: 1903-01-08
Granted: 1904-01-08
Abstract: 541. Poulsen, V. Jan. 8. Telephone signals, recording ; phonographs.-Relates to apparatus of the character described in Specification No. 8961, A.D. 1899, for recording and reproducing telephone messages or signals. The record is made in lines side by side on a continuous magnetically-homogeneous surface. Fig. 1 shows apparatus in which clockwork m drives a vertical shaft d through belting c. The shaft d carries a disc p on which rests the plate n which receives the magnetic record. The record is made by means of an electromagnet a, Fig. 5, the core r of which is brought to a conical point at s. The electromagnet is held between the spring jaws 1, Fig. 3, of an adjustable carrier, secured to a guidebar h, Fig. 1, which slides in bearings i. The carrier is traversed by means of a screwed shaft g, with which meshes a half-nut 8. The screwed shaft is rotated by a worm and wheel from the shaft d, the electromagnet then moving radially along the plate n and producing a spiral record. An arm 11 extending downwards from the carrier controls the brake of the clockwork mechanism, so as to vary the speed in proportion to the radial distance of the electromagnet, and to stop the mechanism when the record plate is filled. Provision is also made for varying the speed by hand. The whole device may be covered by a lid, the movements of which open and close the circuit of the transmitter battery. The erasure of a conversation from a record plate may be effected by means of a permanent magnet, or an electromagnet, or a polarizing-current. The magnet pole or poles are preferably made wide enough to open simultaneously several lines of writing. Several hearing magnets may be employed, to allow the conversation to be communicated to several subscribers simultaneously. The electromagnet may be guided by grooves in the record plate, in which case lateral adjustment to bring it exactly over the line of writing is not required. The Provisional Specification describes also the use of a record cylinder or cone held on a mandrel, and of thin record plates wrapped or coiled helically or otherwise on a mandrel. Where the surface is a plane, the writing may be in lines like those of a book. The record plate may be of steel, nickel, or electrolytically deposited iron &c. A continuous polarizing current may be led through the writing-magnet to improve the quality of the record. Such current should be opposite in direction from that which is used for erasure.

Patent GB-190322267-A (GB)
Title: Improved Device for Removing Steam from the Heating Surfaces of Steam Generators.
Inventor: COCKBURN SIDNEY MANTHORP
Filed: 1903-10-15
Granted: 1903-12-10
Abstract: 22,267. Cockburn, S. M. Oct. 17, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Evaporative efficiency, increasing.-To enable the steam which is generated against the surfaces of heated plates and tubes to ascend readily to the steam space of the boiler and to give place to water, there are provided funnels, wings, or deflectors in conjunction with directing pipes or channels ; or the pipes may be perforated and used without funnels &c. The exact form that the devices may take is dependent upon the structure to which they are applied. Fig. 2 shows a simple form within a depending water tube a, a series of funnels, such as c, is secured about the steam ascensional pipe a, into which the steam bubbles pass through openings such as b. The upper end of the pipe a is within the steam space of the boiler. Fig. 5 shows the application of steam extractors to the tubes'of a Belleville boiler. A steam-escape pipe a, perforated upon its upper surface, is fitted to each tube of the boiler. Each pair of pipes is connected to ascensional tubes i which conduct the liberated bubbles to the steam space of the superposed drum. The extracting- pipes are supported by discs f. Small passages k permit of the escape of steam from the headers. Fig. 8 shows the application of the steam extractors to a marine boiler. Transverse perforated pipes a, connected with troughs F, are formed with vertical portions n reaching to the steam space. Hoods C and pipes P are also employed. Instead of using perforated pipes with wings forming hoods, the pipes a, Fig. 13, may be threaded through the end plates of a hood q. Similarly, the appliances may be fitted to boilers of the locomotive type. Owing to the crowding of the smoke tubes within the barrel, a row of tubes may give place to transverse extracting troughs from which pipes ascend between the remaining tubes. When the device is fitted to a boiler of the Babcock and Wilcox type, the extracting pipes, which are laid within the lower tubes, lead into ascensional pipes situated within the headers. In the next higher tubes, as also, if desired, in the lowermost tubes, the perforated pipes are omitted and short branches substituted. Semicircular discs are added to prevent the backflow of the liberated steam.

Filed: 1903-11-17
Granted: 1904-01-07
Abstract: 25,029. Dean, S. A. Nov. 17. Time-checking apparatus for workmen. In a a time-recorder, paper sheets are carried upon cylinders and are covered by carbon sheets so that the pressure of a stylus will give a record, the cylinder being rotated and moved parallel to its axis by a spring motor under the control of a clock. Upon the front casing of the apparatus are the dial of the clock 11, Fig. 2, and movable studs by which the workmen record. A shaft 44, driven uniformly by the clock, carries two escape-wheels 46 engaging with pallets 42 on the shaft 41, which drives a fan on the shaft 43<1> and is itself driven by the spring 17 of the motor through the fusee barrel 24 and train 26, 27, 28, 29, 31, 37, 40. The motor is wound by a handle on the shaft 30, which is provided for the purpose with a friction clutch consisting of a loose disc 33 with spring arms 32 gripping between them the gear wheel 31, driving being effected between the pinion 29 and disc by means of a ratchet-wheel 35. Upon the screwed end of the shaft a nut is carried, which not only acts as a stop for the winding, but indicates by a pointer 77 and fixed scale 76 how far the spring is wound, the yoke 78 and guide 79 preventing rotation of the nut. The recording cylinders 18, 19 are loose on the shafts 22, 23, but are forced by springs 56 into engagement with adjustable driving-pieces 54 secured to the shafts, longitudinal motion of the cylinders taking place as the screwed ends of the shafts rotate in nuts carried by the casing 2. The recording and carbon paper sheets engage with pins on the cylinders, and are further secured by an external elastic band round the centre, the preferred ruling on the sheets being shown in Fig. 12, the vertical lines of which are, when in position, parallel to the axis of the cylinder. Numbers along the horizontal edge represent hours, and the small numbers downwards the days of the week ; large numbers identify the employee. To record, an employee moves up his external numbered slide 70, Figs. 8 and 9, until the stud 22 comes to the largest part of the slot 71 and can be pressed in so as to force the spring 67 with pointed tip against the carbon paper and thus make a continuous record. Simultaneously the spring 73, displaced by the lug 72, returns the slide which engages with the narrowed part of the stud and locks it in the recording position until the employee operates the slide and stud on leaving work. Preferably, contact with the springs 73 is arranged to complete an electric-bell circuit.
