Title: Improvements in Dynamo Electric Machines.
Inventor: LAMME BENJAMIN GARVER
Filed: 1900-04-12
Granted: 1901-03-23
Abstract: 6947. Lamme, B. G. Feb. 26, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Transformers; converting alternating and direct currents.-Relates to improvements in the polepieces of dynamos, motors, and rotary converters, for the purpose of overcoming the irregularities due to the cross-magnetization of the armature and the consequent distortion of the magnetic field. Fig. 2 shows a front view of a field-magnet polepiece and its surrounding coil 4. The pole-piece is slotted or grooved in a direction parallel to the armature shaft so as to form a number of teeth 2. Each tooth is surrounded by a ring 3 of copper or other good conducting-material, seated in the grooves so as not to encroach upon the air gap. The bands or rings are forced into the grooves so that good contact exists between them, and the pole-piece as a whole is therefore surrounded by a conducting-ring. Fig. 3 shows part of a rotary field magnet. In this case the teeth 2 are undercut, and wedges 5 are driven in to prevent displacement of the rings 3 by centrifugal force. A grid 6 of copper &c. may be cast to fill the spaces between the pole-pieces, as shown in Figs. 4 and 5, and, when it is cast in position on the pole-piece, the teeth 2 may be undercut as shown in Fig. 6. When the pole-piece is detachable from the field magnet, as shown in Fig. 7, the grid 6 may be provided with flanges 7 to support the magnetizing- coils. Wires may be employed in place of strap conductors or cast grids.

Title: Improvements in Means for Locking or Fastening a Series or Set of Drawers, Trays or the like.
Inventor: FORTUNE WILLIAM WALTER
Filed: 1900-12-17
Granted: 1901-11-02
Abstract: 23,057. Fortune, W. W., and Lambert, A. W. Dec. 17. Furniture, locking two or more parts simultaneously. - Relates to means for simultaneously locking or fastening cabinets, or nests of drawers, trays, &c. Each drawer 1 is provided with a lug 2 formed with a recess to receive a locking-bar 4. The bars 4 are connected together to form a frame, which works in guides 5 and is preferably mounted on rollers 6. The parts mounted on rollers are slightly inclined, so as to tend to bring the bars out of engagement with the lugs. The frame is connected by a link 9 to one arm of a bell-crank lever 10 pivoted to a plate secured to the cabinet. In order that the locking-apparatus may be operated by the opening or closing of the drawer 1*, a rod 13 is connected to the other arm of the lever 10 and passes through the arm of a lever 14, a pin on the end of the spindle engaging the face of the arm. A spring 16 encircles the rod, and is interposed between a fixed washer bearing against the lever 10 and a movable washer bearing against the lever 14. The arm 14<a> of the lever 14 is forked to receive a pin 20 on the drawer 1*. Upon closing the drawer, the pin 20 operates the lever 14, which shoots the locking- mechanism through the spring 16. Should a drawer not be properly closed, the spring yields, as the locking-bar cannot enter the recesses in the lugs. The frame may be secured in the locking position by locking the drawer 1*, or a bar 21 connected to the lever 10 and extending through the drawer 1* is provided with a recess, which may be engaged by the bolt of the drawer lock when the frame is in the locking position. The rod serves as an indicator to show the position of the frame, and may be so arranged that the drawer 1* can only be locked when the frame is in the locking position. Instead of actuating the frame by means of the drawer, it may be operated by the rod 21, which is provided with a lever, knob, or finger-piece for this purpose. The mechanism may be so arranged that the frame moves vertically instead of laterally, and in some cases the spring is dispensed with, or some other yielding device employed.

Granted: 1904-10-26
Abstract: 1291. Cristiani-Mayall, A. V. Jan. 19. Printing; developing ; lamps, actinic.- Relates to an automatic apparatus for printing from negatives on a continuous roll of sensitive paper, and a device for developing the prints. The apparatus is designed to be worked by hand or by a motor. The apparatus designed to be driven by a motor is shown diagrammatically in plan in Fig. 19. The band of printing-paper is drawn from the spool A, by the traction roller 26, passing down between it and the pressing-roller 29 to the receiving-roller B. Between the rollers A and 26 the paper passes under the negative, against which it is pressed intermittently by a presser pad which is moved up and down by the cam 20, on the axis 18. The axis 18 is rotated by gearing from the wheel 1, which is driven by a chain and weight. The roller 26 is rotated intermittently by chain gearing 7, 6 from the axis 18, the roller being disengaged at intervals from the gearing by a clutch 49 controlled by a cam 19. A hinged shutter, which opens to admit light to the negative when the paper is stationary, is actuated by a cam 21, and the electric printing-lamp is switched out during the movement of the paper by a cam 21<a>. The speed of the machine is regulated by a governor 2 driven by gearing from the driving-wheel 1. The speed of this governor is regulated by an adjustable lever, the end of which presses against the disc 2<i> when the required speed is exceeded. The mechanism may be stopped by a hand-brake, or it may be stopped automatically at intervals by a brake 2<c>, which is put on by electromagnet 2<d>, an electric bell being rung at the same time. The electromagnet is energized when its circuit is closed by the index - finger of an indicator 4, this index-finger having been set any required number of exposures behind the point of contact. The indicator is actuated by a tooth 5 on the wheel 7. To keep the paper tight, pressure is applied to a brake disc A<2> on the axis of the roller A. The printing operation can be carried on in daylight, as the rolls of sensitive paper are enveloped in black paper when out of the box. The developing-device, Fig. 8, consists of a frame with a roller at the top over which the sensitive paper p is drawn and laid upon a sheet of oilcloth W. The developing-solution is then applied to the surface by a brush or sponge, or mechanically by a roller.
