Title: Improvements in or relating to Dynamo Electric Machines.
Inventor: PORSCHE FERDINAND
Filed: 1903-03-10
Granted: 1904-03-10
Abstract: 5561. Porsche, F. March 10. Dynamos, regulating.-In a driving-system for a motor car or other vehicle in which a dynamo driven by an explosion engine &c. supplies current to electric motors which drive the wheels, the voltage of the dynamo is regulated automatically to keep the watts constant, so that the explosion engine constantly works at the most efficient power and speed however the load on, the speed of, and the current taken by the motors vary. Figs. 1 and 2 show an arrangement in which the required regulation is effected by the cutting in or out of field - magnet coils. The field magnets 3 are mounted loosely on a fixed sleeve 4 within the armature 2, and are constrained by a spring 8 attached to them and to the fixed bracket 24. When the motors slow down through an increase in the :road resistance, the increased current taken by them from the armature 2 increases the attraction between the armature 2 and field magnets 3, thereby drawing the field magnets round against the action of the spring 8. The field - magnet winding 9 consists of a flat spiral of copper band having its coils insulated from each other but bare at their edges. The brush 10 supplying the exciting-current is rigidly held over an insulating- plate in an inclined recess 11 in the winding 9 with one corner in contact with the edge of the outer coil. When the field magnets are moved round as described above, the brush 10 contacts with coils lying within the outer coil, so that the magnetic field is reduced, the final result being that the voltage falls to maintain the watts constant. A shaft 5 carrying arms 6, 7 which project through slots in the sleeve 4 into the field magnets is connected to a dash-pot 15 to steady the motion of the magnets. The above arrangement may be applied to the case in which resistances are switched in or out in parallel to the winding 9 for the same purpose. In another case, a stud on the magnets engages in a helical groove in the sleeve 4, so that the magnets move along the sleeve and increase the gap between their inclined faces and those of the armature when they are drawn round by the armature. The commutator brushes 17 are supported from brackets 19 on the field magnets in the first case, and thereby maintain their proper position relative to the field. In the second case, they are carried from a ring which is rotatable on a fixed bearing and through holes in which pass pins projecting from the magnets parallel to the dynamo shaft ; in this case also the brushes move round with the field.

Abstract: 5606. Downes, A. J. March 10. Cauterizing - appliances ; forceps.-A resistance 5, Fig. 1, of platinum &c. is contained in a recess in one jaw of a pair of surgical preasure-forceps or the like, from which it is insulated except at the end by mica or other insulating-strips 6. When a current is passed through it, it heats the whole jaw of the forceps. It is covered in by a piece 7, which forms one of the acting surfaces of the forceps. This piece has bevelled edges, or is made with square lips, as shown at 7<a>, Fig. 9, and is slid into place longitudinally. It may be secured in position by soft solder having a melting-point sufficiently low not to interfere with the temper of the steel. The strip 5 is connected at its ends to copper terminals 8, one of which is in contact with the jaw of the forceps and so with the terminal 9 ; the other is connected by an insulated conductor 11 to the terminal 10, which is insulated from the forceps by a plug 13. The surrounding tissues are protected from the heated jaw by a shield 20, which has spurs 21 which are sprung into notches or recesses in the jaw. The conductor 11 may pass along the handle of the forceps, being contained in a tunnel formed by a groove covered over by a bevelled piece like the piece 7. Fig. 4 shows a heating- appliance which may be connected to a forceps or other instrument, not specially modified. It consists of a block 16 containing a heating-atrip 17 and furnished with terminals 9, 10. It is grooved at 18 to fit on to one jaw of the forceps.

Title: Improvements in Circular Warp Knitting Machines.
Inventor: HILL HENRY
Filed: 1903-10-31
Granted: 1904-09-22
Abstract: 23,650. Hill, H. Oct. 31. Circular knitting- machines ; warp knitting - machines. -The seamless tubular fabric produced may be employed as the foundation of mantles for incandescent gasburners. The needles A are carried in recesses on a cylinder B, supported by a bracket extending downwards from a horizontal table. The needles are operated by a sleeve D carrying pins engaging with the forked end of a pivoted lever driven by a grooved cam on the main shaft. The threads H pass through guide-rings I, J attached by arms to supporting-rings I<2>, J. The ring I<2> forms a seating for the ring J<2> and is itself carried in the fixed ring K. In most classes of work intended to be produced, the threads from the upper ring cross those from the lower. The rings P, J' are angularly reciprocated by means of pins thereon, which engage forked levers, pivoted on a vertical axle, and driven by suitably-cut cams. The threads thus transferred over several needles are brought to the back of the intermediate ones by radial curved blades Q which, by moving downwards, draw each thread H to the inside of the needle-cylinder. The needles then ascend and knit with their respective threads. The blades Q radiate from a boss on the shaft R, carried in a bracket on the fixed ring K. The shaft R is moved up and down by a lever driven by a suitable cam. The finished fabric passes to take-up rollers mounted below the cylinder B and driven from the main shaft.

Title: Improvements relating to Electric Distribution Systems
Inventor: HALLBERG JOSEF HENRIK
Filed: 1903-11-03
Granted: 1904-06-30
Abstract: 23,863. Hallberg, J. H. Nov. 3. Dynamos, regulating.-In a constant-potential distributing-system, the voltage of the main generator is controlled by an auxiliary generator supplying either the field current of the main generator or current opposed to the exciting- current from another source, the auxiliary generator being driven by a motor which varies in speed according to the work to be done in the system. In one arrangement, the armature of the motor D, Fig. 1, is fed from a constant-potential source E and the field from across the distributing mains branching from the generator A, so that a drop in the potential of the system due to increased load speeds up the motor D, and consequently the auxiliary generator B, thereby increasing the field current of the generator A. This arrangement may be modified by causing the source E to add to the current obtained from the generator B in addition to feeding the motor D. In a second arrangement, the feeding of the motor armature and field circuits is reversed from that described, so that an increased load in the system reduces the motor speed. The auxiliary generator in this case supplies current in opposition to the field current supplied by a second generator which is driven by belt gearing from the main generator A. This arrangement may be modified by dispensing with the second generator and taking the exciting-current of the generator A from the leads of the system. When applied to an alternating- current system, the second arrangement described above is altered by the use of a variable-speed induction motor connected across the leads, the arrangement of the first and second auxiliary generators being as before. Fig. 5 shows an arrangement in which the motor D is excited by two windings, one connected to the constantpotential source E and the other in series in one of the leads ; the motor armature current is taken from a centre of distribution F. The auxiliary generator C acts in opposition to the exciting- current taken from the leads to the field circuit of the main generator A.

Title: An Improved Mode or Process of Manufacturing Refractory Material.
Inventor: MIDDLETON ROBERT
Filed: 1903-12-31
Granted: 1904-11-03
Abstract: 28,731. Stell, A., Stell, G., and Stell, J. Dec. 31. Spindle apparatus; doffing-arrangements; bobbinapplying apparatus; thread-severing arrangements. -Doffing-apparatus, of the class described in Specification No. 22,252, A.D. 1901, for spinning, doubling, and twisting machinery, is constructed with a series of spring clips a, Figs. 1 and 5, arranged opposite the caps c of the spindles e, and pivoted to a bar b, which is operated in a similar manner to the corresponding bar in the prior Specification. Pivoted below the rail b are a series of bell-crank levers h carrying a bar k, on which are mounted, opposite the bobbins d, pronged plates k<1>. By the movement of a lever m acting through a link m<2> and rod m<3>, the plates k<1> can be advanced below the flanges of the bobbins. Prior to doffing, the necessary slack, or length of yarns between the delivery rolls n, n<1> and the bobbins, is obtained by moving a bar o, which is provided with fingers o<1> and mounted in bearings at the end of rack bars o<3>, longitudinally in its bearings, the bar being afterwards moved clear by withdrawing the racks by means of pinions in a shaft o<7> rotated by hand gear. The yarns are next brought to the same side of their respective spindles by small projections on arms q and mounted on a rod q<1>, which, after being rotated to bring the arms into position, is moved longitudinally in its bearings. The rail b is now advanced so that the clips a embrace the caps c below flanges c<1> formed on the caps, and the lever m is then operated to move the plates k<1> below the flanges of the bobbins. The further movements of the rail now lift the caps and bobbins clear of the spindles, carry the bobbins into position to be deposited on pegs or the like by the withdrawal of the plates k<1>, bring the parts into position with respect to a set of empty bobbins so that the plates k<1> can be advanced below the bobbin flanges, and finally carry the empty bobbins and the caps into position on the spindles. The rail is then moved back to leave the spindle apparatus clear, and the arms q are operated to move the yarns from one side of the caps to the other side so that they partially surround the empty bobbins ready for re-starting the machine. The threads extending from the spindle apparatus to the doffed bobbins pass into notches formed in a grooved bar s carried by the rail b and in a bar t capable of sliding longitudinally in the bar s, and the bar t is moved, either by hand, or by a fixed cam groove acting on the end of the bar, as the rail b descends to carry the bobbins and caps into position on the spindles, so as to grip the yarns between the sides of the notches, whereby the yarns are broken when the machine is started. The Provisional Specification states that, with slight modifications, the arrangement is applicable to flyer frames.

Title: Improvements in or Additions to Index Cards, Index Guides, Index Pages and the like.
Filed: 1904-04-18
Granted: 1905-03-02
Abstract: 8905. Kenrick & Jefferson, and Jefferson, F. April 18. Filing papers.-Relates to the tabs of index cards used in connection with card-index filing systems. These tabs frequently fray with wear ; to prevent this, the index card is made by doubling over a sheet of manilla or other strong paper and pasting the doubled sides together. The top portion of the card is cut away along the fold, except the part B which serves for a tab ; by this means, the upper edge of the tab is uncut and is less likely to fray. Another method is to make a slot in the folded edge and insert a metal plate. A perfectly flat card will result if a piece of paper of the same thickness as the metal be inserted, before pasting, between the doubled sides. A complete metal plate may be used as a foundation for the double paper, and the paper sides may constitute pages of a loose-leaf book.
