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. |

|
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. |
