Title: Improvements in Machine Tools employing Worm Gearing for Dividing Purposes.
IPC: B23F5/20
Filed: 1917-06-16
Abstract: 110,325. Muir & Co., W., Melloy, J. H., and Owen, W. June 16, 1917. Gear-cutting; backlash, preventing.-Means are provided for compensating for wear and preventing back-lash in the worm-gearing driving the work-tables in machines for cutting toothed gears and in other machines employing worm gearing for dividing purposes. The invention is shown as applied to a bobbing-machine such as is described in Specification 6595/11, in which the work is carried on a table rotated by a worm-wheel b driven by a worm d. The worm spindle is carried in a cradle n of semi-circular cross-section which is secured at p into a bracket a carried on the machine-bed. A lever r pivoted in the bracket a has an arm passing through an opening in the cradle n and bearing on the working surface of the worm d under the pull of a spring s. The other end of the lever r carries a contact point which as shown is just clear of a fixed point v. As the worm rotates, the lever swings through the angle shown by the dotted lines, and on the completion of one revolution, a gap t in the worm allows the lever to return to the position shown. When the worm shows appreciable wear, the position of swing of the lever r varies and the contact-points complete an electric circuit and give an audible or other signal. The attendant can then, by means of a hand-wheel z and wormgear, rotate the cradle n and move the worm to the left to compensate for the wear. In a modification, the wear is compensated for automatically by arranging the lever r to vibrate a pawl on a ratchet-wheel in such a position that when the lever vibrates through its normal arc the ratchetwheel is not moved. When the position of the arc changes owing to wear of the worm, the pawl engages a tooth and rotates the ratchet-wheel and through the gear described above rotates the cradle n. The worm d has one end parallel to the thread and has mounted alongside a similar ended worm-piece c free to move endways on the spindle. The other end of this piece c is severed to taka a nut h which bears against a thrustwasher m and is secured to one end of a coiled spring, the other end of which is secured to the pin r. This spring tends to rotate the nut h so as to push the piece e to the right so that the thread bears on the back of the teeth on the table b and prevents back-lash.

Title: Improvements in lathes for turning shells and the like
IPC: B23B5/00
Filed: 1940-02-23
Abstract: 541,799. Turning projectiles. HEPBURN, J. T. Feb. 23, 1940, No. 8722/41. Divided out of 541,777. [Class 83 (iii)] A lathe for turning shells or the like has a bridgelike structure 64A carrying a pair of spaced tools 66 which are fed vertically to cut the work to length. The tools are mounted in slides 65 operated by pneumatic cylinders 67 working in tandem with oil cylinders 68, the latter having adjustable byepass circuits 72 controlled by valves which may be set to vary the rate of feed of the tools. The shell is mounted on an expanding driver 24 and supported by a tailstock 32 the body of the shell being turned by tools arranged as described in Specification 541,800. In operation, after positioning the shell, a foot valve 76 is, depressed to admit air to lines 78, 79. A retarding-valve is placed in the line 78 to ensure that the tailstock spindle 32 is moved up before the cylinder 27 actuates the driver. A switch 80 is then operated to start the spindle driving mechanism (not shown). Connected to the main air line is a valve 81 having a foot controlled bleed valve 83 which is operated to allow air flow to lines 84...87. This engages a clutch in the saddle driving train which is operated as described in Specification 541,801. At the end of its travel the saddle engages a valve 88 which allows air flow through the valve 89 to cylinders 67 to impart down feed to the cutting-off tools. When cutting off is completed a valve 102 is actuated to close the line to the upper ends of the cylinders 67 and admit air to the lower ends thus withdrawing the tools. At the end of its movement the saddle also actuates a valve 92 to admit pressure to line 93 to operate the clutch of the saddle feed mechanism. At the end of the operation a valve 77 is actuated to admit pressure to line 100 to withdraw the tailstock and disengage the driver. A switch 17 is actuated to stop the shell rotation before the work is released. If the saddle fails to engage the valve 92 it will contact a limit switch 101 to switch off the driving motor. Specifications 541,777 and 541,802 also are referred to.

Title: Improvements in or relating to universally mounted gyro-verticals or artificial horizons for craft
IPC: G01C19/44
Filed: 1942-06-30
Abstract: 558,684. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. June 30, 1942, No. 8999. Convention date, Dec. 19, 1940. [Class 97 (iii)] In a universally and neutrally mounted gyro-vertical or artificial horizon provided with erecting means (for example pendulous shutters controlling air jets) deviations of the gyro from the vertical during lateral acceleration or bank accompanying a turn or change in speed of the craft are prevented by including in the gyroscope means for applying a countertorque in opposition to the disturbing torque applied by the erecting means. As shown in Fig. 1, when the craft turns and centrifugal force, acting on the erecting shutters 9 applies a disturbing torque, the banking movement of the craft, relative to the gimbal ring 3 displaces a two-way valve and admits air from a pipe 16 to one or other of two nozzles 11, 12 carried by the gimbal 3, and by directing an air jet on to a toothed sector 10 attached to the rotor casing 5 counteracts the disturbing torque. To prevent this counteracting torque from operating during the initial setting of the gyroscope, the air supply to the pipe 16 may be cut off manually by a valve operated from a handle 23, or may be automatically cut off by a sylphon bellows 25, Fig. 3, connected to the exhaust pump of the gyro. In a modification, Fig. 8 (not shown), the air jets from the nozzles 11, 12 are controlled by a shutter carried by a pendulum which swings out when the craft turns. In further modifications, the air to the counteracting nozzles is controlled from the rudder connections of the craft, or when the craft is equipped with an automatic pilot for example as described in Specification 416,813 the nozzles are controlled from the air pipes of the servomotor system of the directional gyroscope. Specification 393,695 also is referred to.

Transmitting systems; modifying musical renderings before transmission, to improve quality of reception.-In the broadcasting of music, the electrical controls of the broadcasting apparatus are situated adjacent to the musician and his instrument, and the musician or an adjacent operator listens-in and operates the controls so as the correct the distortion introduced, by the broadcasting train. The listening-in apparatus may be connected to a receiving aerial, or to the microphone or other circuit of the broadcast transmitting apparatus. The performer or adjacent operator is rendered deaf to the direct rendering by wearing a sound-proof helmet fitted with telephone receivers, or, in the case of an organ, the keyboard may be situated within a sound-proof room and the organ pipes outside, a loud-speaking receiver being also arranged within the room. The electrical controls may be placed within reach of the organist, and may be interlocked with the organ controls. For example, the swell pedal may be interlocked with the volume control of the broadcasting-apparatus, so as to prevent " blasting." An automatic player may be substituted for the performer. In the case of an orchestra, the conductor may be enclosed, together with the broadcasting controls and a loud-speaking receiver, in a sound-proof cabinet with glass walls to enable the players to see him. He may also wear a sound-proof helmet with telephone ear-pieces. The Specification as open to inspection under Sect. 91 (3) (a) refers also to an alternative method of broadcasting, in which a preliminary correct rendering is transmitted, and a person listening to the faulty rendering received by wireless prepares a revised musical score which, when followed by a performer, will give a true rendering to the radio listener. The score may also comprise indications for adjustments of the electrical controls of the broadcasting apparatus, which controls may be actuated by the performer or by a separate operator. This subject-matter does not appear in the Specification as accepted.
