Title: A system of involute gears and their generation
IPC: F16H55/08
Filed: 1950-01-17
Abstract: 690,338. Gear-cutting and finishing. KITCHEN, H. E. Jan. 17, 1950 [March 2, 1949], No. 1245/50. Drawings to Specification. Class 83 (iii). [Also in Group XXIV] A method of generating a system of involute gears having the same base pitch but with varying diameters, consists in so relating them to a single pinion-type cutter for producing them that at'least the desired length of contact is generated on each gear, the lengths of contact being approximately equal. The calculations for cutting a pair of gears are set forth, given the cutter, the centre distance and the numbers of teeth of the pinion and gear. A desired length of the path of contact is first specified and an addendum assumed for the pinion. The dimensions of a gear to mesh with the pinion are then calculated, including the length of the contact. If this is less than the length first specified, a new addendum is assumed and the calculations repeated. Alternatively, a new length of contact could be specified or the diameter of the pinion reduced. By modifying the teeth of the cutter, a similar modification may automatically be imparted to each gear. A shaving cutter of almost identical dimensions to the pinion-type cutter may be used for finishing.

Filed: 1926-01-21
Abstract: 259,900. Siemens & Halske Akt.- Ges. Oct. 17, 1925, [Convention date]. Chromium, depositing; moving electrodes; electrolytes, circulating. - In the deposition of chromium or the interior of a tube 3 connected as cathode and located within a stationary electrolyser 1, the internal anode 4 is moved vertically relatively to the tube by means of a wire 9 which also serves as an electric connection. In the apparatus shown, an external anode 5, similarly movable, is provided for external coating. The anodes are provided with insulating beads or projections 11. The length of the anodes is about one-tenth that of the tube 3. At starting they are let down till their lower edges coincide with that of the tube and electrolyte is introduced to a level just above the upper edge of the anodes. The current is then turned on and the anodes raised at a uniform speed by hand or by clockwork, electrolyte being introduced by a cock 13 so as to be always just above the anodes. This procedure is necessitated by the use of an electrolyte which attacks metals in the unpolarized condition. The tube 3 may be supported by wires which also serve as electric connections.

Filed: 1916-02-09
Abstract: 103,697. White, A. E., (Riter-Conley Manu facturing Co.). Feb. 9, 1916. Apparatus fitted to transporting-apparatus sliding-weight apparatus.-The weighing-apparatus described in Specification 12142/15 is adapted for transferring loads from one level to another The receptacle or hopper 21 containing the material, e.g. discharged coke, is suspended from a beam 11 pivoted in bearings 10 on a swinging arm 8 carried by a travelling platform 2, and the counterbalancing-weight 21 is threaded on a screw shaft 22 operated by a reversible electric motor 24. Assuming that the hopper is balanced and in position to receive coke from a retort, a roller 28, Fig. 3, on a weighted arm 26 pivoted tc the beam 11 is engaged by a flanged sector 25. If coke is then fed into the hopper the balance is upset, the arm 26 is tilted to close a gap d, d<1> in the motor circuit, and the motor 24 can be started by operation of the controller 100. When the balance has been readjusted by the weight 21, the circuit is automatically broken at the gap d, d' owing to the downward movement of the free end of the beam. The hopper can then be swung round and lowered, and the coke can be fed to the producer. This again upsets the balance, and the beam tilts slightly until a hook 30 engages a weighted latch 31, which restrains further movement. In this position, the latch also engages a pivoted lever 57a to close a gap d<2> d<3> in the reverse motor circuit, and the controller can again be operated to restore the balance. The controller is shown in Fig. 3, and comprises a pivoted head 52 carrying contacts 50, 50<1> and 51, 51<1>. Included in the circuits of the motor are solenoids 55, 56 for operating pairs of pivoted catches 55<a>, 55<b>, and 56<a>, 56<b>, which engage shoulders 53, 53<1>, and 54, 54<1> respectively. The upper catches 55<a>, 56a prevent operation of the controller until one or other of the gaps d d<1>, d<2> d<3> has been closed by the tilting of the beam, and then movement is allowed only in the required direction. One or other of the lower catches holds the controller in operative position during the running of the motor, but when the circuit is broken after the restoration of the balance, the catch is released, and the controller is returned to normal inoperative position by the springs 49. Overrunning of the motor is prevented by a solenoid-operated brake. For weighing the coke supplied to the producer, the shaft 22 is geared to a suitable indicating or recording mechanism 75 through a chain 78 and a pinion 77 operative in one direc-

[Also in Group XIII] A method of making a radiator panel from sheet metal comprises passing a pair of confronting sheet metal strips step-by-step through a press separately to form in each strip grooves which when the strips are placed together constitute flow ducts transversely of the strips and conduits connecting the ducts lengthwise of the strips, welding the strips face to face transversely and between the ducts, cutting the welded strips transversely to form panel assemblies and seam welding the lengthwise edges of the strips. A pair of sheet metal strips 11, 12 pass through a reciprocating press 24 comprising a punch member 38, a reciprocable member 40 having a punch and die on its top and bottom faces respectively and a fixed die member 39, one sheet passing between the members 38, 40 and the other between the members 39, 40 to form transverse ducts 13 and conduits 14 in each strip. A feed mechanism 25 which draws the strips through the press 24 and advances the formed strips a duct pitch to a spot welding apparatus 26 when the press 24 is open comprises a pair of hydraulically operated pusher assemblies attached to the piston-rods 43 of which are pusher bars 42 shaped to receive a duct 13. The apparatus 26 comprises a row of hydraulically operated pressing cylinders 47, each carrying a welding electrode 48 which coacts with a block 49 in a known manner to spot weld the panels together along the portions 15 while the press 24 is closed. The welded panels pass to a cutting mechanism 27 comprising a carriage 52 mounted on rails 65 and an hydraulic ram 55. The carriage 52 supports a pair of hydraulic rams 56 to actuate a pair of shaped clamps 57 which grip the panel causing the carriage 52 to move under the influence of the strip feed mechanism 25. An electrically driven saw 63 mounted on a transverse slide 60 within the carriage 52 is actuated along a guide rod 61 by an hydraulic cam unit 66 to cut the continuous panel into the required lengths, through the portion 15, which are then delivered to a conveyer 28, the carriage subsequently being returned to its start position by the ram 55. The panel is manually passed to a seam welder 29 comprising rollers or discs 67, 68 to weld each edge 17 of the strips and is finally torch welded along the side edges 19 and the openings 20 fitted with connectors and closure plates. The hydraulic rams are controlled in a predetermined sequence by a number of electrically actuated relays and solenoids via an electrical control unit which also operates in a predetermined sequence a series of control switches. The edges 19 may be seam welded between a pair of rollers 100, 101 which are provided with a cut out corresponding to the shape of the conduit 14. The panels may be passed through staggered straightening rolls 106, 107, 108 after leaving the seam welder 29.
