Thesame patentee has several ingenious applications of Indian-rubber to carriages to wheeltires, to the bosses of wheels, to shackle pins, and to the axle. Brulffes Patent.—(See list. No. 30,^1^. 147.) This inventor proposes to use Spencerscones in blocks of wood, instead of iron confining rings. A series of them are enclosedin a case formed in the side timbers of the underframe of the railway truck or carriage;the cup space is formed in the block of wood, as our figure shows, and no guide rods are 299. required: the same principle is applied to draw and bearing springs. The advantagesproposed by this arrangement are, the dispensing with guide rods and the taking the ulti-mate blow on blocks of wood, which deadens its effect; they are said to answer verywell, and are used almost exclusively on the South Western and Bristol and Exeter Rail-ways. 14Y
