Improved Mechanism for Operating Change Speed Gears of Traction Engines, Heavy Motor Cars, and Other Machines
|
Sydney T. Pagesmith |
, England |
Abstract:
Traction engines; motor road vehicles.-In change-speed gears for traction engines &c., the sliding wheels are moved in and out of gear by means of a single handle through the medium of a combination of a cam-slotted lever or levers and bell-crank levers. Fig. 1 shows the invention applied to a two-speed gear. The cam-slotted lever n is pivoted to a fixed bracket, the slots engaging the ends of bell-crank levers which operate the pinions. A movement of the lever to the left throws the wheels E, e into gear, no movement of the lever k taking place. Similarly a movement of the lever to the right places the wheels D, d in gear. A pin, placed in one of three holes y in the bracket, locks the lever in the 'in' or ' out' of gear position. Fig. 3 shows the invention applied to a three-speed gear. The slotted lever r is pivoted to a second slotted lever p itself pivoted to the bracket. The ends of the levers have overlapping lugs s, t, and, when these are connected by a pin, they become in effect one lever and operate the wheels d, e as in the former case. If now the pin be placed in the hole v to lock the lever p, the hand-lever moves about its pivot r<1> to clutch the wheels d,f together for the third speed. |

Detachable Wheel and Braking System for Steam-Wagons and the Like
|
Percy W. Sirett |
, England |
Abstract:
Detachable driving-wheels of steam wagons &c. are secured to flanged sleeves b, f, one of which is connected directly to the axle and the other to the differential gearing. The sleeve may carry the brake drum p, or a separate brake drum may be used. The fastenings consist of conical headed bolts j, the heads of which project through the part f into partly conical bores in the wheel m. The flange f and brake drum p are enclosed substantially within the rim of the wheel. The end of the wheel hub projects into a recess in the sleeve b. |

Demountable Wheel
|
Samuel C. Street |
, England |
Abstract:
In detachable and interchangeable wheel systems it is a known expedient to demount ably connect a wheel on its axle by multiple small screw bolts which pass through the boss of the wheel and the flange of an axle sleeve serving as a permanent hub on the one hand or as a differential sleeve on the other. An object of the present invention is to so connect a wheel for drive of rotation from the corresponding axle or from the corresponding sleeve of the compensating gear by a cross pin drive, the axes of whose members run parallel with the wheel axis, and with wedge action reacting on both parts to be joined that a few large bolts will serve, no more than two working well, also that an effective countering of that tendency to distort and unfigure the pins and the walls of their co-acting holes or passages to set up lost motion with consequent striking and hammering action shall be made possible. And simultaneously with doing this, better facilities are given for removing and replacing a wheel, these facilities inter alia allowing any wheel according to the system of the present invention to be, interchanged with any other wheel according to the same system provided only that the wheels are true to the same standard.
Claim:
In apparatus of the class described, in combination, a hub element provided with an outwardly extending member, a wheel provided with a member adjacent said first member, substantially registering openings in said members each of which in each member is shaped with substantially the same taper, tapering connecting members passing through said registering openings and haying substantially the same taper with each of the same, and means adapted to tighten said connecting members. |
