Title: Improvements in or relating to gear changing systems
IPC: F16H61/02
Filed: 1936-05-27
Abstract: 472,856. Controlling change speed gearing. MASSOLO, L. J. May 27, 1936, No. 15014. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 28, 1936.] [Class 80 (ii)] Oppositely-acting pawls 130, 130<1>, operated by links 24, 24<1>, connected to a vehicle clutchpedal 16, are permitted to engage and turn a toothed-wheel 122 on a speed-selecting cam shaft 116, under the pre-selective control of depressible means, such as a treadle 30, Figs. 1 and 2, or two electric push-buttons, carried by the clutch-pedal itself. The directional sequence of a change is thus predetermined by rocking the treadle 30 in one direction or the other, or by depressing either button, the change being subsequently effected by two complete depressions of the clutch-pedal 16. A complete depression, without rocking the treadle 30 merely disengages the clutch. The pawls 130, 130<1> may be controlled by electric solenoids, energized by the pushbuttons, or as shown, the treadle 30 acts on each pawl mechanically through a tensioncable 28 or 28<1> which serves to retract one or other of a pair of rigidly-connected pivoted arcuate guides 140 or 140<1> away from the toothed-wheel 122, and at the same time allow the other guide 140<1> or 140 to approach the wheel under spring-influence, the guides having arcuate grooves slidably receiving laterally projecting pins 134 on the pawls. The pawls are pivotally carried on rock-arms 126, which are turned in opposite directions on the selector camshaft 116 by the clutch-pedal links 24, 24<1>. The selector-cams shown control three forward speeds, reverse being under separate manual control, not shown. The low speed selector 166, Fig. 5, is controlled by a threearmed lever 150, one arm 160 of which cooperates with a neutralizing cam 146, Fig. 7, whilst another arm 158, in a different plane, co-operates with a low-speed establishing cam 144. The second- and high-speeds selector 178 is controlled bv a three-armed lever 152, arms 170, 172 of which are operated by a four-lobed cam 148, which also constitutes a kind of interlock for locking the selector 178 in neutral when the low-speed selector 166 is operative. Each depression of the clutchpedal 16 turns the selector camshaft through 60‹, two successive depressions being necessary for each change of speed, the first neutralizing the gear and the second engaging the new speed, up or down. A complete depression of the clutch-pedal when running in highspeed with the gear selector operative for an upward change, restores the gear to the initial neutral position.

Title: Improvements in machines for forming screw-threaded necks on glass vials
IPC: C03B23/09
Filed: 1933-05-26
Abstract: 408,826. Glass manufacture. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Kimble Glass Co. ; Vineland, New Jersey, U.S.A.) May 26, 1933, No. 15286. [Class 56.] Relates to the formation of screw-necked glass vials by means of apparatus in which a plunger is inserted in the open end of a blank while the glass is plastic, and a roller with a screw groove on its periphery is pressed against the exterior of the blank in order to roll a thread on the glass. According to the present invention, the groove 15, Fig. 1, does not extend the full length of the roller 14, so that the thread formed on the glass does not reach the mouth of the vial and the end of the neck can be made sufficiently flat to enable it to be sealed tightly by means of a cap. The glass tube or blank 10 is supported and rotated by any usual apparatus, and after the end of the blank has been heated to plasticity, a flat non-rotatable plunger 11 having an abutment or shoulder 12 is moved into the blank. A neck-forming tool 13 is then moved into contact with the blank and co-operates with the shouldered plunger to shape the softened end of the blank into a suitable neck with a flat end, as shown in Fig. 4. Next, the threaded roller 14 is brought into contact with the neck and is rotated by contact with the glass and forms a screw thread in the neck. Since the groove 15 does not extend the full length of the roller 14, the glass formed into the thread is not squeezed on to the end of the neck and does not interfere with the formation of a flat end by the shoulder on the plunger 11.
