Lathes.-The invention consists of multiple speed and reversing gearing and has special reference to motor road vehicles, but it is applicable to other apparatus, such as lathes, A two-speed gear by which reversing can also be effected is shown. The motor drives a shaft G, on which are screws F, F<1> of opposite senses, the pitch of the latter being less than that of the former. A third screw F<2> is of the same pitch as F, but of the same sense as F'. The screws mesh with wormwheels E, E<1>, and E<2> of equal size, on the shafts of which are carried loosely pinions A, A', A<2>, gearing together and with a pinion B on a shaft C whence motion is conveyed to the wheels of the vehicle. The pinions A, A', A<2> are provided with suitable clutches, by which any one of them can be fixed on its spindle. The pinion A drives the shaft C directly, A<1> drives it in the same direction through the pinion A which is then idle, while A<2> drives it through the idle pinions A and A<2> in the reverse direction. The changes of speed can be effected by making the wheels E and E<1> different in size instead of in the number of teeth, and arrangements may be made for reversing at any particular speed or more than one speed. In the case shown, the operation of reversing is performed without reversing the motor, but the device may be otherwise arranged.

Granted: 1900-03-31
Abstract: 25,565. Lamson Pneumatic Tube Co., [Lamson Consolidated Store Service Co.]. Dec. 27. Pneumatic despatch apparatus.-The carriers are propelled through a single tube in both directions. The carrier to be despatched is dropped into the conveying-tube D through a vertical tube B connected to it by a valve box C, and the air pressure is turned on by using a handle E to open a valve whereupon a flap valve C<3> closes the entrance tube. On arriving at the other terminal the carrier closes its flap valve C<3> by striking a finger J which forms part of a lever J<2> that is connected to the counterbalance K<3> of the valve by a link K<1>. With both valves closed, the air pressure becomes sufficient to blow out a diaphragm L<1> in a cup L, and so trip a detent lever L<4> which engages the starting hand-lever E. The air pressure supply is thus cut off, and the air in the conveying-tube escapes through small orifices in the two flap valves till they fall open and a spring resets the detent lever.
