Abstract

274,014. Jerram, A. E. April 1, 1926. Differential gearing; clutches.-In a power. driven lawn-mower the roller is driven through epicyclic differential gearing and a manually controlled clutch and the cutter through a clutch that slips and gives an audible warning when the cutter is obstructed. The main shaft 51 drives the cutter 20 through a slip clutch 62, 63 and chain gearing 59, 60, 61, and the main roller 24 through a change speed gear 56, a clutch 85, 186, chain gearing 84, 102, 86, reducing spur gearing 104, 105, and differential gearing 113. The transmission gearing is housed in the frame member 12 which forms an oil bath. The clutch discs 62, 63 are ribbed or corrugated so as to make a noise when the clutch slips. The spring- controlled disc 62 may be drawn back out of engagement by rotating a nut 70 on a spring- pressed bolt 66 in the end of the shaft 51, a pin or key on the bolt passing through a slot in the shaft and engaging the hub of the disc 62. The clutch 85, 186 comprises two series of discs pressed into engagement with one another by a bolt 187 passing through the shaft 75 and controlled by a spring 91, a lever 94, and a Bowden wire 96, a thrust ball bearing being provided between the bolt 187 and a hardened steel pin 100 on the lever 94. The rear roller consists of a central drum 112 and two end drums 110, 111 connected to it by differential gearing comprising two annular wheels 114. 115 mounted on sleeves 116, 117 carrying the drums 110, 111. Keyed on the axle 87 is a pinion carrier 118 having four arms 119 - - 122 arranged in pairs on opposite sides of a central boss 123 and each carrying a pinion. The four pinions intermesh in pairs 124, 125 and 126, 127 and the pinion 125, 126 mesh with the annular wheel 114 and the pinions 124, 127 with the wheel 115. A flanged ring 130 of H-section has driving connection with the carrier 118 and is secured to the central drum 112. Acsordin<g> to the Provisional Specification the main roller is divided into four parts the two inner ones being driven by differential gearing and driving the two outer ones through an escapement mechanism forming a one-way clutch device.
