Title: Improvements in Machines for Making Moulds for the Casting of Metals, and in Moulding Boxes for same.
Filed: 1905-07-17
Granted: 1906-05-31
Abstract: 14,652. New Hygienic Stove Co., and Greenwood, E. P. July 17. Moulding.-A moulding-machine has a pivoted frame 2, Fig. 1, provided with an opening large enough to take the biggest pattern used ; for smaller patterns the opening is reduced by auxiliary frames. The pattern plates are secured by pivoted pieces 4, Fig. 3, and carry a pattern on each side. The boxes are secured to the plate by a pin 6 with holes 6<1>, 6<11> for cotters 7, Fig. 3<a>, with long gibs 7<1> extending to the front of the machine to facilitate knocking out. In a modification, the pins 6 are secured to the moulding box by bolts at a distance adjustable by set-screws. Fork stops 11 lock the frame 2 in position as controlled by a lever 151. A compressing-beam 21 is controlled by toggle mechanism 22, 17, 18, and its side rods 20 have guides 24, 25 which permit it to be swung aside, as shown in dotted lines, when not required. A mould-carrier 33 runs on a rise-and-fall table 26 and on a bracket 34 to facilitate removal. The table is controlled by linkage 27, 28, 30 and a retaining-quadrant 32. The table and compressing- mechanism may be coupled together. To prevent damage by shock occasioned by a slight fall of the table due to the pawl just missing a tooth of the quadrant, a spring table, Fig. 5, may be used. The Provisional Specification states that such a spring table may be made portable for use in making light and delicate moulds. The sand is rammed by placing wooden blocks upon the surface and striking them with a hammer. Flasks may be rammed thus without the use of a spring table, and a trolly may be arranged to run over a series of flasks and carry a drop weight suspended by a chain or rope.

Title: Improvements in Signalling Apparatus for Railways and other purposes.
Inventor: HUGHES GEORGE
Filed: 1906-01-22
Granted: 1907-01-17
Abstract: 1589. Hughes, G. Jan. 22. Recording signals.-An apparatus for recording signals sent between block telegraph and other sigualling-instruments on railways or other signals communicated electrically or by telegraph comprises electromagnetically-operated levers pressing a clockwork-driven paper strip upon type-wheels for printing the time of operation, the number of repetitions of the time. record indicating the character of the signal. Mechanism for starting and stopping the clock-work or other motor for driving the record-strip is also described. Two electro-magnets B, B<1>, Figs. 1 and 2, are provided for the outward signal and the reply, and their. pivoted armatures D, D<1> carry pads E, E', which press a paper strip G upon time type-wheels C driven by a clock F, carbon or inking ribbon M being provided. The strip G is wound from a drum H on to a drum H<1>, preferably by a driving- roller J driven by a clock-work, spring, or other motor and provided with a tension roller K. The paper strip is moved at each recording operation, the motor being provided with a braking-mechanism for this purpose comprising a pivoted lever S, Figs. 4 and 5, carrying a pin T which normally engages with a pin U on the governor spindle V to stop the motor. When either coil P or P<1> of an electro-magnet O is energized by the signalling current, the armature Q attached to the lever S is depressed and the pins T, U are disengaged, allowing the motor to start. A spring Y restores the lever S to its normal position, and this movement is retarded by a dash-pot W to allow sufficient movement of the paper strip before the motor is stopped. The number of repetitions of the same printed time indication indicates the number of successive operations of either magnet armature D, D<1>, Fig. 2, which corresponds, say, to the number of bell strokes in code signalling, so that the interpretation of the recorded times can be made.

Title: Improvements in Wireless Telephony and Telegraphy.
Inventor: COLLINS ARCHIE FREDERICK
Filed: 1906-02-26
Granted: 1906-12-20
Abstract: 4691. Collins, A. F. Feb. 26. Telegraphs ; telephone systems.-Relates to transmitting and receiving signals or articulate speech by means of electric impulses, the earth or other medium being used as a conductor, the object being to provide for the use of any currents at any required voltage, thus rendering the system practicable over larger distances than heretofore. In Fig. 1, the circuit A comprises a source of electromotive force 1, an arc light 2, and conductor terminals 3, 3<1>, connected to earth. In parallel with the circuit A, or the heavy-current circuit, is the shunt circuit B, which includes a telephone transmitter 4 and a resistance 5. Any change of resistance of the circuit B owing to the variable pressure of the diaphragm is impressed upon the circuit A, and alters the temperature and resistance of the arc, thus producing electric vibrations in the earth or other medium. In modifications of the transmitting-device, transformers are used between the arc lamp and transmitter circuits. To use the system for telegraphy, a key is substituted for the telephone transmitter. As a receiving-device, a 'single telephone receiver having its terminals embedded in the earth may be used. To increase the amplitude of the impulses so that the reproduction of speech may be louder, an apparatus similar to that shown in Fig. 1, except that a telephonic receiver is substituted for a transmitter, is used, as shown in Fig. 5. The received impulses are superimposed and impressed upon the current flowing in the circuit A, thus varying the resistance of the arc 2 and increasing the variations of current from the generator 1 flowing through the circuits A, B. Fig. 9 illustrates a modification, comprising a circuit A with a source of electromotive force 1, an arc light 2, and terminals 3, 3<1>, embedded in the earth. The circuit B is influenced by the variation in the illumination by the arc 2 of a selenium cell 4 which is in series with a source of electromotive force 5 and a telephone receiver 6. In another modification, one coil of a transformer is placed in the arc-lamp circuit, the other being in the receiver circuit, and in another an intermediate circuit containing coils of two transformers is used.

Title: Improvements in and relating to Apparatus for Suspending or Supporting Arc Lamps and like Articles
Filed: 1906-03-29
Granted: 1907-01-17
Abstract: 7587. Crompton & Co., and Spencer, A. E. March 29. Hooks.-A suspended arc lamp &c. is alternately supported and released by raising it to its highest position, by means of a supporting-hook and releasing-lever, the mechanism being independent of gravity or springs and therefore capable of working in any position. Fig. 1 shows the apparatus in the position in which a lamp is supported, and Fig.-4 shows the position of the hook and lever when the lamp is about to be lowered. The fixed part of the mechanism comprises a hood b with downwardly-projecting guide, c for the pins k, which are carried by a U-shaped casting h and are guided into correct angular position by the curved surfaces l. Rollers may be provided to ensure free running of the pins in the guides c. When the lamp is raised, the pins k<1> first engage the underside m of the hook d and swing it over to the left, and then engage and raise one arm of the lever e, causing a pin p attached to the lever to engage a notch r, and to force the hook to the right, so that, when the pins k<1> are lowered, they rest in the recesses of the hook d. As the hook d is forced into the central position, the pin p becomes disengaged from its notch, and the parts are as shown in Fig. 1. In order to lower the lamp, the pins k<1> are again raised and engage the under surface of the lever e, thereby lifting the pin p into a second notch v, Fig. 4. If the rope is then slackened, the pins k<1> first strike the part m of the hook and release the locking-pin from its notch, and then pass down the other arm of the lever e, leaving the mechanism re-set for a subsequent raising of the lamp. The casting h carries the contact-plugs, if these are provided, and is connected to the lamp by a universal joint. The apparatus may be inverted, so that the hook and lever are carried by the movable part, and -the U -shaped casting h is fixed.

Title: Improvements in or relating to Gyroscopes.
Inventor: ANSCHUETZ-KAEMPFE HERMANN
Filed: 1906-05-01
Granted: 1906-07-19
Abstract: 10,184. Kaempfe, H. Ansch³tz-. Sept. 9, 1905, [date applied for under Patents Act, 1901]. Gyroscopic apparatus. - To adapt a gyroscope for use as a compass for navigation or the like, the axis of rotation is arranged to remain in an horizontal plane, and an adjustable weight is provided to give a movement of precession to the axis, so as continually to restore it to its position and maintain it fixed relatively to the earth, the counteracting effect of friction being annulled by a movable weight. The fly-wheel a, which is shown in plan in Fig. 3, is suspended in the usual manner in a frame f rotatable on a vertical spindle g. The inner frame d carries the precession weight, a graduated nut i, a scale k for netting the nut, and the weight for compensating for the friction consisting of balls m, or it may be fluid in. a suitably bent tube i. The weight i is adjusted according to the latitude, and when the axis e, e becomes inclined, the balls m roll slightly outward and increase the precession effect, thus overcoming the effect of friction, which tends to put the gyroscope into its new centre-of-gravity position at the expense of the precession movement.

Title: Improvements in or relating to the Separation of Beryllia from Alumina and Iron.
Inventor: BRAN FRIEDRICH
Filed: 1906-07-14
Granted: 1907-05-30
Abstract: 15,973. Bran, F., and Oordt, G. van. July 15, 1905, [date applied for under Patents Act, 1901]. Beryllium hydrate and carbonate. - Beryllia is dissolved from a mixture of the hydrates of aluminium, iron, and beryllium by alkali bicarbonates or an alkali and carbonic acid. The solubility is further increased when the hydrates have been precipitated from their solution in caustic alkali by means of carbonic acid. In one of the examples, a solution in caustic soda of the mixed hydrates is treated with carbonic acid or sodium bicarbonate and carbonic acid until all the alkali has been converted into the acid carbonate. The hydrates are by these means first precipitated, the beryllia afterwards going into solution on the formation of the acid carbonate. Beryllia can be obtained from this solution by beating, diluting, or precipitating with alkalies. In the other examples, the mixed hydrates are treated with sodium carbonate and carbonic acid, or acid sodium carbonate with or without carbonic acid.

Title: Improvements in the Regulation of Electric Currents subject to Large Fluctuations of Load.
Inventor: TILNEY MAX JAMES ECCLES
Filed: 1906-07-14
Granted: 1907-07-04
Abstract: 15,988. Tilney, M. J. E. July 14. Regulating.-In the method of regulation described in Specification No. 27,168, A.D. 1904, the three exciting-coils of the motor actuating the regulator are replaced by two coils arranged to oppose each other. One of these coils carries a current proportional to the voltage of the circuit, while the other carries a current proportional to the output of the generator when the latter is delivering current. When the battery alone is delivering current, the second coil carries a current proportional to its output, while the first is connected in series to the booster field. The regulator motor E is provided with three field coils e, e', e<2>, of which only e and e<1> are operative when the generator A is delivering current, while e and e' are operative when the battery B alone is supplying current. These pairs of coills always oppose each other, and the common coil e is arranged, by means of a change-over switch, to be connected across the resistance R<1> when the generator A is operative, and across the resistance R<2> when the battery alone is operative. When the switch is thrown over to the left, the terminals u<1>, v<1> contact with the terminals u, v, the booster field coil c being at the same time connected to the regulator D through the bar R, and the coil e<1> connected across the circuit leads. When the switch is thrown over to the right, the terminals u, v contact with another pair of terminals, the booster coil c being connected to the regulator D through the field coil e<2>. When the brushes of the regulator are in the position indicated by X, Y, the current in the booster field coil c is in one direction, and, when they are in the position X<1>, Y<1>, the current in the coil c is reversed. A modification is described for maintaining the output of the generator constant while the battery is discharging, and to reduce the output when charging and the charging-current has reached the maximum value allowable. In this case, the regulator is connected in series with the generator shunt-winding, and actuated by a motor governed by two field coils, one carrying a current proportional to the charging and discharging 'battery. current, while the other is connectedacross the circuit leads. In order to compensate in the regulator for over-correction, due to the time constant in the inductive field circuit of the generators, current and voltage coils may be added to the regulator motor field, one connected across the circuit leads in series with the field winding of the booster and the regulator and arranged to assist the current winding, while the other is connected across the circuit leads in series with the regulator, and carries a current which varies in the same manner as that in the preceding coil but arranged to act in opposition thereto. This compensation arrangement may be applied to an auxiliary machine coupled to a mechanical device for storing energy in place of the electric storage battery.

Title: Single Trigger Mechanism for Double Barrel Guns.
Inventor: BRENIZER ORSON WILLBERT
Filed: 1906-08-29
Granted: 1907-02-28
Abstract: 19,288. Brenizer, O. W. Aug. 29. Single-trigger double-barrelled guns.-Figs. 1 and 2 are side elevations showing the parts in position for firing the right barrel first ; Fig. 4 shows the parts in position for firing the left barrel after the right has been fired. Fig. 5 is a plan showing the parts in the first position. Fig. 7 is a section on the line c-c, Fig. 5. The sears 7, 8 are released by the arms 38, 39 of a hub 37 carried on a plate 6 sliding longitudinally in the trigger. The plate 6 is retained in the forward position shown in Figs. 1, 2, 5, and 7, against the action of the compressed spring 12, by means of a tooth 26 on the slide plate 6 engaging in a notch 25 of a spring-controlled arm 20 pivoted to the fixed support 4. When the trigger is first pulled, the sear 7 is released by the arm 38, the slide-plate tooth 26 being lifted into the notch 27 of the support 4. The rear edge of the notch 27 is slightly to the rear of the notch 25 in the arm 20, so that when the trigger is released and carried down by its springs the tooth 26 presses on the top of the bar 20, and, owing to the trigger spring being stronger than the spring of the bar 20, the bar is pressed down and the slide-plate 6 carried to the rear by the spring 12 as soon as the tooth 26 leaves the notch 27. To prevent accidental discharge of the second barrel by the involuntary pull, the motion of the slide 6 is retarded by a pendulum escapement 31, carried by the slide and working in teeth 30 of the trigger blade. The parts are then in the position shown in Fig. 4, the arm 39 being under the sear 8 in readiness for firing the left barrel. To fire the left barrel first, the hub 37 is turned from the position of Fig. 8 to that of Fig. 9. This is effected by means of an arm 48, pivoted to the trigger blade and connected by a bar 58 to an actuating-button 51. When the button 51 is pushed from one extreme position to the other, the arm 48 is turned and acts upon one of the sliding plates 46, shown separately in Fig. 11, engaging by their rear ends 45 in a diametral groove on the under surface of the hub 37, so as to turn the hub. When the button 51 is in the middle position, the trigger is locked by the stud 61 on the trigger blade engaging the stud 60 on the plate 50. The slide plate 6 is re-set when the top lever is operated by a cam 16, which is mounted on the lever spindle and engages the pivoted lever 14, pushing the upper end rearwardly, so that the bifurcated lower end engaging the projection 13 of the rod 10 draws the slide plate 6 forward.
