Title: Improvements in associating mechanism for printed products
IPC: B41F13/54
Filed: 1926-05-28
Abstract: 267,761. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). May 28, 1926. Delivery apparatus; associating-apparatus; signature gatherers; cutting-apparatus.-In a machine for delivering printed products, such as pamphlets, magazines, &c., in sets, each set is printed and associated as one product, which is divided into its units by slitters, the units then being assembled in sets so that each set can be distinguished from the preceding or succeeding sets. The machine shown in Figs. 1 and 3 deals with a printed and associated product comprising three units. This product is first folded transversely by cylinders 1, 2, and then passes, with its folded edge leading, between guides 3, 4 where it is divided into the three units by longitudinal slitters 5. The units are then delivered, by pusher fingers 17, between guides 6, 7 to a slotted stop-plate 13, actuating means being provided for the guides and stop-plate so that whereas one set of units is allowed to pass through the slot 14 in the stop-plate to forwarding rollers 15, 16, alternate sets are stopped by the plate 13 until the guides 6, 7 have turned through a semicircle so as to reverse the units, whereupon the plate allows them to pass to the rollers 15, 16 with the non-folded edge leading. Curved guides 42, 43 prevent the units from slipping out of the guides 6, 7 as they are rotated. As each set leaves the rollers 15, 16 and drops on to a table 22, guides 209, 210 deflect the two extreme units 51, 53 out of the plane of the centre-unit 52, as shown in Fig. 6, whereupon side-pushers 72, 73 move the units 51, 53 into line with the centre one 52. The set thus arranged is moved into a delivery box 75 by a reciprocating pusher 74, and alternate sets thus delivered have their folded edges upward, so that the sets can be distinguished from one another in the box 75. The guides 6, 7 are attached to brackets 8<1> journaled in the framework of the machine carrying at one end a gear wheel 11 and at the other end a cam 12. A rack 20, Figs. 1 and 3, reciprocated from the main shaft 30 through a cam 27 on a shaft 31 and links 23 - - 26, oscillates the gear wheel 11 through intermediate gearing 18, 19. The cam 12 actuates an arm 50 on a shaft 45 carrying another arm 46 projecting through apertures in the stop-plate. 13 so as to reciprocate the plate at the desired times. A cam 76 on the shaft 30 actuates a bell-crank lever 78 so as to reciprocate the pusher 74, and another cam 32 on the shaft 31 actuates, through links 33 - - 36, the pusher fingers 17. The side pushers 72, 73 are mounted on racks 56, 57 in engagement with gearwheels 61, 62 geared to the shaft 30 so as to rotate in opposite directions.

Filed: 1947-05-22
Abstract: 631,761. Shuttering for moulding walls and beams. BROTTENBERG, W. May 22, 1947, No. 13819. [Class 20(ii)] [Also in Group XXIII] A wall or beam moulding section comprises, a number of wooden boards fixed edge to edge in rigid connection by couplings a, Figs. 1, 3, formed by forcing pointed rods e, Fig. 5, of wood or steel &c. between steel strips or bands c positioned in transverse channel ways d cut through the boards. The couplings may consist of either one or two rods e forced between two or four spiked bands c to each channel way d, the spikes b penetrating the wood of the boards so that the bands and rods strengthen the section against warping and tensile stresses. The bands may have their ends bent at right angles either over the adjacent edges of the wooden boards or over the ends of the rods. In a modification, Fig. 8 (not shown), the couplings do not each completely traverse the wall moulding section from edge to edge. The wall moulding sections may be secured together to form the intended wall mould by wooden supports and co-operating iron  straps.

Title: An improved method and apparatus for producing cylindrical gears
IPC: B23F9/10
Filed: 1929-05-03
Abstract: 331,973. Mammano, B. May 3. 1929. Gear-cutting; milling-cutters. - A number of toothed wheels or racks are generated simultaneously by means of tools which rotate round a fixed axis, the individual tools engaging successive teeth on continuously rotating gear blanks which have their axis parallel to the plane of movement, of the tools. In Fig. 2 four tools I - - IV rotating round a fixed axis 0 are shown in operative relation with four gear blanks which rotate in the direction of the arrows f<1> - - f<4> at speeds such that while a particular tool 1 in moving from 1 to 1<11> traces out a curve S<11> on a gear blank. After a tool head rotation of 90‹ the tool IV reaches position 1 and cuts the next successive space on the blank. Any other number of tools may be employed and any convenient number of blanks may be cut simultaneously. In some cases the tool head may be fitted with tools on both sides and the gears R may be of different. sizes as shown in Figs. 5 and 6 provided that in each case the ratio of the angular speed of the blank to the angular speed of the tool is equal to the ratio between the number of tools and the number of teeth to be cut. In order to generate the tooth surfaces the blank axis is translated in a plane parallel to the plane of movement of the tools and corresponding rotary movement is superposed on the blank rotation by means of a differential gear or similar mechanism. For roughing gears the generating movements may be dispensed with and the gears may be located as shown in Fig. 6. Instead of single tools X, Y, V, W engaging in successive tooth spaces on a blank, a number of auxiliary tools may be arranged along a spiral V1, V, V2, Fig. 8, to operate in the same tooth space as the tool V. The tools W, X and Y may be similarly supplemented by additional tools arranged along spiral curves. Some of the tools may be adapted forroughing and others for finishing operations, or, in some cases, successive tools may operate on alternate sides of the tooth space. In another modification, Fig. 9, milling tools M or grinding wheels may be employed, these tools being rotated on their own axes in addition to the planetary movement about the central axis 0. In another modification, Fig. 11, pointed tools I may be, employed, these tools being fixed to a tool disc D rotating round a, central axis Z. In order to shape the whole flanks of the teeth such tools are moved relatively to the gear blank along a line such as e, f, or, for cutting cycloidal gears, the. line of movement, of the tool point may be along a cycloidal curve.Preferably the tool disc is kept stationary and the movement in the direction e, f is imparted to the gear blank. Any particular gear blank may be positioned or removed on completion without stopping themachine and automatic means may be provided for slowly advancing the gear blank to the working position and withdrawing the gear rapidly on completion of the operation.

Title: Improvements in or relating to the regulation of hydraulic gears or couplings
IPC: F16D33/16
Filed: 1926-06-01
Abstract: 262,002. Bauer, G., and Schmieske, C. June 1, 1926. Hydraulic transmission of power.- Hydraulic couplings for driving accumulator pumps in hydro-electric installations, are automatically filled and emptied in dependence on the load on the driving turbine. The coupling 10, Fig. 1, has a primary member 11, Fig. 2, mounted on the shaft of an electric generator 3 driven by a tur. bine 1, and when wholly or partially filled its secondary member 13 drives a pump 6 lifting water to a reservoir 7 for subsequent use in a turbine 8 driving a generator 9. Water is admitted through a pipe 15 to the coupling through an inlet valve, controlled by a governor operated from the generator 3. When the load on the generator is greater than normal, the inlet valve is closed, and an auxiliary valve 23 closes a port 29 by which pressure liquid normally passes through a pipe 28 to act on the outlet valve to keep it closed. The outlet valve then opens and the coupling empties. In order to prevent overheating, a continuous stream of water is maintained by means of outlet apertures 35 and inlet apertures not controlled by the inlet valve,

Title: Improvements in and relating to multiple electric motor actuator systems
IPC: B64C25/24
Filed: 1946-05-08
Abstract: 612,136. Controlling aircraft. BRITISH THOMSON-HOUSTON CO., Ltd. May 8, 1946, No. 13916. Convention date, May 11, 1945. [Class 4] [Also in Groups XXXV and XXXVII] In an actuator system, for operating the wing flaps of an aircraft for example, comprising two electric motors driving a load through a differential gear, and-locking means for arresting the operation of either of the motors if it is not energized, automatic means for sequentially energizing the motors are provided in order to reduce the starting current, obtain smooth operation, and avoid high transient stresses in the operated equipment. Two electric motors, 6 and 7, are coupled to input shafts 8 and 9 of a differential gear 10 the output shaft 15 of which is coupled to a load, for example the wing flaps 2 of an aircraft. When both motors are operative the shaft 15 is driven at a speed proportional to the sum of the speeds of the motors, and, in the event of failure of one motor, the shaft 15 continues to be driven at half-speed without the load on the operative motor being increased. As shown, the motors are of the series splitfield type, and, when a reversing switch 35 is moved to a " lower " position, a relay 39 is energized to close a contactor 28 for forward operation of the motor 6. When the switch 35 is moved to its other operative position, a relay 42 is energized to close a container 30 for reverse motor operation. The motors 6 and 7 are started in sequence to prevent heavy initial current surges. For this purpose a relay 44 is provided having its operating- coil connected across the armature of the motor 6. The relays 32 and 34, which control the supply to the motor 7, cannot be energized until the back electromotive force of the motor 6 is sufficient to close the relay 44. Ganged switches 36 and 37 are provided so that a motor may be operated in either direction when the other motor is jammed or otherwise inoperative. Normally the ganged switches are in the position shown, but when they are moved to the centre position the relays 28 and 30 are directly responsive to the movement of the reversing switch 35, and, since the relays 39 and 42 are opened, the contactors 32 and 34, controlling the motor 7, cannot be closed. Thus, if the armature of the motor 7 is shortcircuited, tripping of the main circuit-breaker is prevented. Similarly, movement of the switches 36 and 37 to the right-hand position, allows independent operation of the motor 7 when the motor 6 is damaged. In the event of failure of either motors the associated input shaft is locked. This is effected by solenoidoperated brakes, the coils of which are respectively connected in series with each motor armature so as to be energized, to hold-off the brake, and de-energized, to apply it, simultaneously with the motors.
