Title: Improvements in Dynamo Electric Machines
Inventor: HEYLAND ALEXANDER
Filed: 1902-07-21
Granted: 1903-08-21
Abstract: 16,205. Heyland, A. July 21. / Dynamos and motors, alternating-current.-Relates to methods of winding alternating-current machines, with sections in parallel but connected to different commutator segments, to prevent sparking, and also to enable currents to be transformed into currents of any periodicity or into direct currents. Fig. 2 shows a three-phase winding, with the three phases each divided into two parallel parts a<1>, a", b<1>, b<11>, and c<1>, c<11> respectively. The self-induction produced by the current interruption in one section of the winding of a phase will be neutralized by the neutral induction of parallel-wound section of the same phase which is then closed. For example, in Fig. 4, while the segments 2, 4, and 6 of the commutator are in contact with the brushes, the sections a', b<1>, and c<1> are in circuit, and the segments 5,1, and 3 with the corresponding sections b<11>, a<11>, c<11> are cut out. On further rotation all the coils are in circuit, and this continues until the brushes leave the segments 2, 4, and 6, when only the sections a", b<11>, and c<11> are in circuit. Diagrams are given showing the method of parallel winding applied in other cases. A similar method of winding is adopted in rotary transformers for changing single-phase or polyphase currents into currents of any number of phases or of any frequency, into single-phase currents, or into direct currents. Fig. 9 shows how this method of parallel-winding is applied to synchronous machines. In this case there is only a single-phase winding which is divided into the two halves a<1>, a<11> wound parallel to each other.

Title: Improvements in Lubricators.
Inventor: CHAPMAN LEONARD
Filed: 1902-10-31
Granted: 1903-09-10
Abstract: 23,823. Chapman, L., and Knowles, W. H. Oct. 31. Lubricators. - R e l a t e s to lubricators for supplying semisolid or thick lubricant, such as graphite and oil. The lubricant is contained in the cylinder 1, in which works the tube 5 having a funnel-shaped handwheel 90 and attached at its lower end to the block 14, having an extension 15 passing through the piston 10. The nut 3 engages the tube 5, and is prevented from rising by the cap 2 screwed to the cylinder 1. The ratchet-wheel 8 has a feather 7 engaging the groove 6 in the tube 5, but does not prevent the tube from rising. The ratchet-wheel 4, having a greater number of teeth than the other, is screwed to the nut 3. The arms 26, mounted to rotate freely on the nut 3 and a boss of the wheel 8, carry a wide pawl 28 engaging both ratchet-wheels. The arms 26 are connected through the ball-and-socket joint 32, and a horizontal arm to the rod 38, having a strap engaging the eccentric 39 on the shaft 40. The arm 38 is clamped by the handle 45 in the adjustable block 46, and rotates with this block on the sleeve 71. By these means, the throw of the arm can be adjusted. The motion of the arm 38 is communicated to the ratchet-wheels, and, in conseqnence of the difference in the number of teeth, the tube 5 slowly descends, forcing down the piston 10. The tube at the same time rotates on the ball bearing 18, turning and compressing the helical screw 23, which acts as a stirrer for the lubricant, tending to raise the solid deposit. The passage 19 is closed by the screw plug 20 provided with a long handle 27. At the end of the downward motion of the piston, the shoulder 47 comes in contact with the boss of the wheel 8 and locks the wheel against the nut 3, with the result that both ratchet-wheels rotate at the same speed, and further vertical motion is stopped. To prevent the lubricant from clogging the outlet pipe 52, Fig. 4, the spiral wire 49 may be attached to the part 15 so as to turn in the pipe and scrape the deposit from the inner surface. Fig. 5 shows a modification intended for semi-solid lubricants when stirring is unnecessary. The piston 59 is fixed and the cylinder 1 is moved vertically in the casing 55 by the ratchet-wheel 4, and is rotated by the ratchet-wheel 8. The handle 56 is provided for rotating by hand. The upper end has a wide opening closed by the plug 57. The piston is free to rotate, with the cylinder, on the ball bearing 63 carried by the fixed tube 60.

Title: Improvements relating to Sighting Apparatus for Ordnance.
Inventor: BARNES ROBERT CHARLES
Filed: 1902-11-04
Granted: 1903-09-17
Abstract: 24,150. Barnes, R. C., and Bauld, R. Nov. 4. Sights.-Relates to a tangent rear sight for machine guns and ordnance, especially Maxim guns. The sighting-carriage B, which can be raised and lowered by means of a pinion D on a spindle D<1> engaging with teeth 0 on the sighting-bar A, is prevented from accidentally shifting its position by the teeth on the end of a spring pawl E engaging with circular rack teeth B<1> on the carriage B, the pawl E being pivoted on pins J on the spindle D<1>. The adjusting-cap G, mounted on the spindle D<1>, is provided with a movable piece H, a projection H<1> on which engages, when the cap G is turned, with one of two inclined projections E<1> on the pawl E, thereby disengaging the teeth of the pawl from the teeth B<1> and causing the spindle D' to rotate with the cap G. When the cap G is released, a horse-shoe spring mounted on the cap brings a projection E<1> on the pawl into contact with projections on the piece H, thereby causing the teeth of the pawl to engage with the teeth B<1>. When it is required to adjust the carriage B rapidly, the movable piece H is forced outwards, so that the projection H<1>, by depressing one end of the pawl, holds the other end out of engagement with the teeth B<1>. A projection H<3> on the piece H acts as a detent when the piece H is in either position, and an inclined portion H<4> of the piece H forces the teeth of the pawl into engagement with the teeth B<1> while the piece H is moving from one position to the other.

Cutting - apparatus ; folding paper; delivery apparatus.-Relates to cutting and folding machines, especially intended for use in conjunction with printing-machines, for cutting sheets from a web and associating them in piles for folding together to form signatures having a considerable number of pages. Fig. 3 shows a sectional elevation, and Fig. 4 a sectional plan, of the machine, and Fig. 6 shows a complete section of the web from which a signature of 24 pages is produced. The web f is slit longitudinally, along the lines a-a, into three narrow width webs by two pairs of slitters e, e', and thence passes round the roller g to transverse c u t t i n gcylinders h, h<1> which cut the web on the lines b-b. Sheets of four pages are thus cut, and these are deposited in two sets of three, one set upon the other, on tables D, D<1>, as shown at S, S<1>, S', Fig. 4. The sheets are placed on the tables D, D', alternately, by three rotary sheet carriers C, C', C' each having two sets of grippers 90‹ apart, as shown at j, j<*>, j<1>, j<1*>, j<2>, j<2*>. The carrier C takes two successive sets of sheets, and deposits them directly on the table D, and the carrier C<1> takes the next two sets and transfers them to the carrier C<2> by which they are deposited on the table D<1>. The grippers are closed by springs and opened by cams z, z<*>, z<1>, z<1*>, z<2>, z<2*> on the framing. The sets of sheets are then collected in piles on the folding- tables F, F<1> for folding together along the central line c, Fig. 6. This collection is effected by grippers on endless racks or gripper carriers E, E<1> moving along each side of the tables D, D' on rollers m, m<1> and in guides G, G. The grippers are in groups of three r, r', r<2>, the grippers r taking the first pair of sheets S by its side edges, the grippers r' taking the second pair of sheets S', and the grippers r<2> taking the third pair of sheets S<2>, and depositing them successively on the table F or F<1>. The grippers are operated by fixed cams s, s', s<2> so as to close on the sheets when in the proper position. Stops q, q<*> are provided on each side of the tables D, D' for registering the'sheets laterally on the tables, and these stops are pivoted so that they swing out of the way as the grippers pass them. The batch of sheets on the table F or F<1> is evened up, against fixed stops v, v*, before folding, by pushers w, w* on arms of shafts 49, 54 rocked from crank-pins on the ends of a shaft 42. The sheets are folded by vertically-reciprocating folding-blades, through the slots 31 in the tables F, F<1> to folding-rollers driven by bevel gear 58 from the shaft 42. The folded signatures are delivered into troughs J, J' having reciprocating packers operated by roads x, x<1> from a rockshaft 64.

Granted: 1904-11-28
Abstract: 26,029. Calthrop, E. R., and Brewer, E. G. Nov. 28. Motor road vehicles are made up of two sections pivoted together, viz., a forward section having a pair of steering and a pair of driving wheels, and a detachable rear section of any form having a pair of driving- wheels only, both pairs of driving-wheels being driven by a motor on the forward section through differential and toothed gearing ; means are also provided for automatically disconnecting the rear driving-wheels from the motor, when the two sections make a certain angle with one another. Figs. 1, 2, and 3 show one form of vehicle. The forward section 1, having steering-wheels 2 and driving- wheels 3, forms a complete vehicle in itself, to which a rear section 6 of any suitable form, having two driving- wheels 7, may be pivoted. The pivoted connection consists of a socket 10 on the rear section resting upon the rounded head of the bolt 8 which is carried in a bracket 9 on the forward section. The motor 4 drives the pinion carrying member 14 of a differential gear through change-speed gear, the two driven toothed wheels 17, 15 of the differential gear being connected to the front and rear pairs of driving- wheels respectively. The wheel 17 rotates freely on the shaft 16, and drives the driving-wheels 3, by means of the flexible shaft 20, worm gearing, and the ordinary differential gearing on the axle. The wheel 15 is keyed to the shaft 16, which drives the rear driving-wheel 7, through the medium of the toothed pinions 16*, 23, gearing respectively with the lower and upper sides of the bevel-wheel 22 which rotates on the pin 8. The pinion 23 is mounted on a shaft which rotates in a bearing 25 carried by the forward section, the bracket for the bearing being formed with a strap 27 which is placed in a circular groove in the bracket 9. Two arms 28 extending downwards on either side of the bearing 25 cause it to turn with the rear section. An arrangement for automatically disconnecting the rear driving-wheels from the motor is indicated at A in Fig. 2, and shown in detail in Fig. 3. The shaft 16 is divided, but the two parts are normally clutched together, the two members 29, 30 of the clutch being kept in engagement by springs. The lever 31 has a lower forked end, and its fulcrum is carried by the forward section of the vehicle. When the two sections make a certain angle with one another, cams 33 on the rear section engage the upper arm of the lever 31 and cause it to disengage the clutch. The shaft 16 may then be held stationary by a brake drum 35 in order that the forward wheels may continue to propel the vehicle.
