Title: Improvements in or relating to a method of and apparatus for mounting a tractor-chain or the like on the wheels of a vehicle
IPC: B62D55/04
Filed: 1931-03-24
Abstract: 375,359. Chain strainers. BURN, L., Tudor Cottage, Longparish, Hampshire, and THOMPSON BROS. (BILSTON), Ltd., Bradley Engineering Works, Bilston, Staffordshire. March 24, 1931, No. 9048. [Class 45.] A track or band is mounted on the wheels of a vehicle by movement of the wheels, the band first being drawn under the wheels by means of a pilot chain coupled to a wheel and to the track, after which the ends of the track are brought together by further movement of the wheels. The track 10 is first placed with one end near one of the wheels 14, 15 as shown in Fig. 2, and a pilot-chain 13, comprising two side chains connected together at intervals by detachable cross-chains, is coupled to the end of the track and at 21 to the driving wheel 15. The wheel 15 is then rotated backwards in the direction of the arrow, and either the track is drawn under the wheels or the vehicle is drawn back until the wheels are on the track. The pilot-chain is then disconnected and the track brought to the position shown in Fig. 4. The ends of the track are engaged by hooks 22, 23 carried respectively by telescopic members 26, 27, Fig. 5. A wire cable 35 is connected by a pin 34 to the member 26 and passes over a pulley 36 on the member 27, its free end being connected to a chain 38 anchored by means of a chain-stop 41 fixed to the vehicle. The vehicle wheels are now rotated backwards again, and since the chain 38 is anchored the ends of the track are brought together so that they can be coupled. The hook 22 is adjustably secured by a pin 31 to the member 26. A plate 37a shrouds the pulley 36 so that the chain 38 cannot pass over the pulley and thus the member 26 cannot be drawn completely out of the member 27. Specification 357,718 is referred to.
