Granted: 1908-02-20
Abstract: 19,722. Parr, A. E. March 29, [date applied for under Patents Act, 1901]. Wheel tracks.-Relates to rails of the type, described in Specification No. 679, A.D. 1872, [Abridgment Class Railways &c.], and having an arch-shaped or hollow base so that they can be laid directly on the ground or ballast and used for ordinary railways or as wheel tracks on ordinary roads, and consists in improved means for connecting the rails together at their ends. The joints are made by an internal overlapping piece 14, the base flanges or edges of which are tapered so that the central portions lie below the lower faces of the rail flanges 6. The rail ends and the piece 14 are locked together by clamps 16 driven into position over the wedge-shaped ends of the plate 14. The tread 2 is made relatively narrow when used for flanged wheels, and wider when used for ordinary road wheels, the rails being maintained at the correct gauge by tie-rods 7. The cavity in the base is filled with ballast to assist in preventing lateral displacement..

Title: Improvements in and relating to Rotary Transformers for Electric Current.
Inventor: PINOT FRANCOIS MICHEL EDOUARD
Filed: 1907-10-11
Granted: 1908-04-16
Abstract: 22,467. Pinot, F. M. E. Nov. 9, 1906, [date applied for under Patents Act, 1901]. Rotary converters.-A rotary converter for transforming single-phase current into continuous current comprises a field magnet excited by the single-phase current, an armature and brushes so arranged that two of the elements may be rotated while the other remains fixed, the rotation of the field magnet and armature relatively to the brushes being respectively equal to and twice the value of the frequency of the alternating current. With the field magnet E, Fig. 2, stationary, the armature I and brushes B, B<1> are rotated at equal speeds but in opposite directions by a synchronous motor M. If either the brushes or the armature are fixed, the other elements are rotated in the same direction, the field magnet E, Fig. 3, being rotated by the synchronous motor M with half the velocity of the other element. The regulation of the voltage of the continuous current is effected by altering the augle between the brushes, or the angle at which the brushes are keyed. When the brushes B, B<1>, Fig. 3, are stationary, their position may be readily altered by means of a screw V and pinion V<1>. The brushes when rotating may be moved by the apparatus shown in Fig. 5, in which the nut e carrying the brushes B, B<1> is screwed upon the sleeve m so that by moving the nut e longitudinally the brushes B, B<1> are rotated. The movement of the nut e is effected by a fork k carried by a nut h engaging with a screw V. The brushes f, f<1> are also carried by the nut h. In a modification, in which the commutator strips are vertical, the brushes B, B<1>, Fig. 4, are displaced by rods t, t<1> carried by the nut e and capable of sliding in the support s, which is held fixed by a spring r'. In this case the brushes f, f<1> are fixed to the guide s<1> in which the nut h slides.

Title: Improvements in Speed and Frequency Indicators.
Filed: 1907-10-22
Granted: 1908-02-20
Abstract: 23,317. Hartmann & Braun Akt.-Ges. Oct. 22, 1906, [date applied for under Patents Act, 1901]. Speed indicators. - In speed instruments having resonant tongues vibrated by impulses from fixed magnets, the tongues are prevented from coming into contact with the magnets by suitably shaping either the magnet pole-pieces or the tongues. Fig. 5 is a plan and Fig. 6 a section of a form in which sets of laminations 1, 7, of the shape shown by the larger outline in Fig. 6, alternate with sets of laminations of the shape shown by the smaller outline, forming spaces in the upper pole-piece of the magnet, in which the tongues vibrate. The tongues are divided into two sets ; the longer ones, responding to the lower frequencies, are arranged on the left side of the magnet, Fig. 6, and the shorter ones, responding to the higher frequencies, are arranged on the right side. The magnetic circuits through the smaller tongues are arranged to be closed more completely than those through the larger tongues, so as to compensate by increased pull for the lesser leverage at which the force operates. The attraction on the tongues may be graduated by varying the length of the projecting pole-pieces g, or by widening the gaps as shown at the lower left-hand gap in Fig. 5, or the gaps may be kept small and the tongues narrowed at the portion opposite the pole-pieces, or slots through which the pole-pieces project may be punched in the tongues. In the modification shown in Fig. 10, the pole-piece p may be continuous or slotted, and the tongue b is bent as shown, and either the whole or only the end portion is of iron. In the modification shown in Fig. 11, the tongue z has a supplementary indicating-tongue z<1> attached to it and is prevented from striking the pole-piece by shaping the latter as shown. By replacing the upper pole-piece of the electro-magnet e by permanent magnets m, spaced apart as shown in Fig. 13, with like poles similarly directed, the pole-pieces are weakened during one half of an alternation and strengthened during the other half, so that the tongues respond to currents of their own natural frequency instead of to currents of half that frequency, the values of the scale readings being thus doubled. In the case where the tongues are in oppositely vibrating pairs, the permanent magnets m, Fig. 14, are arranged with alternately-directed poles. The permanent magnets may be of horse-shoe form to prevent demagnetization, and may be provided with a magnetic short-circuiting device a, Fig. 16, to change the scale values by stopping the polarization when turned through a right-angle. The invention is also applicable to solid magnets and to magnets bent to the shape of a crescent or a cross.

Granted: 1908-10-08
Abstract: 3492. Mõhl, L. Feb. 16, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Liguid meters; counting-apparatus.-In electric and fluid meters of the type in which a spindle rotates at a speed proportional to the rate at which the quantity measured is being used, and in which the spindle registers upon a counter the total quantity used, the counter is arranged to indicate cost at a price per unit which depends upon the time of day and is automatically determined by a clock controlling variable actuating-means. The meter spindle 3 is adapted to oscillate an arm 4 through a constant arc. The arm when moved to the right meets and displaces a curved lever carrying the actuating-pawl 7 for the primary wheel of the counting-train. Between the arm and the lever, a wedge 6 is variably interposed by the action of a cam 15 representing the relation between tariff and time of day and carried by a twenty-four hour wheel of the clock 12. The extent to which the arm 4 may oscillate the curved lever is thus determined. There are two indicators and scales for displaying the tariff in force, and an eccentric 5 introducing a fixed minimum, higher than that on the cam.

Granted: 1909-05-13
Abstract: 23,511. Laukhuff, A. Nov. 4, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Embossing and stamping ; printing on leather.-Relates to a rotary apparatus for cutting, punching, impressing, or stamping paper, leather, &c. The material is pressed by levers against the surface of a cylinder or other rotating body, on which the material is partly wound, and is operated upon by tools fixed on the levers, which rotate with the body. The drawings show a cutting-machine constructed in accordance with the invention. The material is held on the rotating body 2 by two or more levers 5, 6, and is cut by shear blades 18, 19 co - operating with blades 20, 21 fixed on the levers 5, 6. Each of the levers 5, 6 turns on a pivot-pin 7, and has a toothed segment engaging with a rack on the slide 3, which carries a roller 9 held by a spring 11 against the edge of a non-rotating cam 13, the shape of which is shown in Fig. 2. While the roller 9 is above the point d on the cam, the lever 5 holds the material on the rotating body 2, and while the roller 9 travels over the part d, a of the cam, the lever 5 releases the material and moves into the position in which the lever 6 is shown. As the part of the cam above the point d is greater than a semicircle, the material is gripped by the lever 6 before being released by the lever 5. Each of the shear-blades 18, 19 is carried by a lever 14 pivoted on the pin 7 and carrying a roller 16, which strikes against a boss 22 on the edge of the cam 13 and is pressed towards the shaft 1, thereby actuating the shear blade 18 to sever the material. The lever 14 is returned by a spring 23. The material to be cut is laid on the body 2 under the lever 5 when this lever is at the lowest point of the cam, and is rotated with the body 2 until it is gripped by the lever. The material is laid round the body 2 and pins 24, 25 adjustable in slots in lateral castings on the body 2. In the course of the rotation of the apparatus tha material is gripped by the lever 5, the loose end cut off by the blade 18, and the material laid over the pin 25 and on the body 2 under the lever 6, which turns and grips the material before it is released by the lever 5. The shear blade 19 now severs a length of the material, which is immediately released by the lever 5 and falls into a collecting-box or the like. The length of material cut off is determined by the adjustment of the pins 24, 25. If these pins are at different distances from the shaft, two different lengths are cut off during each rotation. The shears 18, 19 may be inclined to the axis of rotation so that the pieces cut are not rectangular. The form of the levers 5, 6 may be varied, and adjacent to or instead of the shear-blades may be carried punches, types, stamps, or similar tools for operating upon the material.

Title: Improvements in Safety Valves.
Inventor: MILLS CHARLES REEVES
Filed: 1908-11-17
Granted: 1909-04-15
Abstract: 24,674. Mills, C. R. Nov. 17. Safety - valves. - A safety-valve for steam boilers &c. comprises a main valve having two valve heads 19, 20, the lower head 20 forming the obturating - member. The upper head, which is of the greater area, is situated in an inner chamber and divides the same into upper and lower compartments 21, 22. Situated at the top of the compartment 21 is a spring-loaded auxiliary valve 24, adjustable by means of a screw 36. The fluid pressure has direct access to the underside of the valve head 20 through the hollow connecting-stem 18 to the upper side of the head 19. When the pressure becomes excessive, it opens the auxiliary valve and puts the compartment 21 into communication with the atmosphere through the passage 23, the compartment 22, the pin valve 40, and, the exhaust chamber 14 formed by the outer casing 9. The main, valve is thereby free to lift by fluid pressure underneath, and the excess pressure is relieved through the passages 13 and the exhaust chamber 14. The auxiliary valve has a large and a small area, the latter only being exposed to the boiler pressure when the valve is closed, but as soon as it is moved from its seat the larger area is exposed to pressure thereby causing it to be opened quickly so as to open the main valve promptly.

Abstract: 26,126. Schlueter, H. W. Dec. 3. Piles; sea and retaining walls; buildings &c., subaqueous; coffer dams ; groins &c., beach; piers and landing-stages; wharfs.- Interlocking metal piles are made with tongues and grooves in communication with the interior so that, on filling with cement or concrete, the filling enters the tongues and surrounds the grooves. Tubes 5, preferably of metal, are made with tongues 15 and grooves 16 of counterpart shape; the end of the tongue of one tube is inserted at the end of the groove of the adjoining tube, and the tongue slides down the groove until the tubes are locked throughout their length. The tubes may be made in sections held together by spring clips on the lower section carrying pins which pass through holes in the upper section, and also through registering holes in an offset portion of the lower section. The first tube sunk is bevelled on both sides, and the subsequent tubes are bevelled towards the tubes already driven, so that there may be no tendency to bind. When in position, the tubes are filled with cement or concrete which may be reinforced. To give finish to a wall, an horizontal concrete beam, which also may be reinforced, is moulded upon the top of the piles. The piles may be arranged to form any desired configuration by making the tongues and grooves in the required position on the pile, and the space enclosed may be filled in with concrete for building solid piers and the like, as shown in Fig. 10. The construction is stated to be applicable for use in the building of wharves, piers, docks, groins, sea-walls, jetties, aud the like, and also for foundations and bridges.
