(4.) A driving and braking mechanism for wheels comprising a wheel-hub, a driving-member, and a brake-actuating member within the hub, a plurality of clutch-dogs having rocking and driving engagement with the driving-member, and adapted to engage either the hub or the brake-actuating member according to the direction in which the driving-member is rotated from a neutral position, and a spacing-ring connecting said clutch-dogs to hold same in proper relation to each other, but permitting a slight radial movement thereof, substantially as set forth. (5.) In a driving and braking mechanism for wheels, the combination with a plurality of clutch-dogs of a spacing-ring connecting said dogs to hold same in proper relation to each other, and pivoted to each of said dogs so as to permit a slight radial movement thereof, said spacing-ring extending slightly beyond the outer surface of each clutch-dog so as to come into frictional contact with the interior of the wheel-hub, substantially as set forth. (6.) A driving and braking mechanism for wheels comprising a wheel-hub, a driving-member, and a brake-actuating member within the wheel-hub and rotatable independently thereof, a brake within the hub comprising a split brake-ring adapted to be expanded to engage the hub, means arranged between the ends of the brake-ring and engaging with the brake-actuating member for expanding the brake-ring when said member is rotated, and a clutch-dog having rocking engagement with the driving-member and adapted to engage with the brake-actuating member to rotate same when the driving-member is rotated backward, substantially as set forth. (7.) In a driving and braking mechanism for wheels, the combination with a wheel-hub, a driving-member, and a brake-actuating member within the hub and rotatable independently thereof, and a cam secured to or formed integral with the brake-actuating member, of a brake comprising a split ring, a wedge-block between the ends of the brake-ring and engaging with the said cam whereby the brake-ring can be expanded when the brake-actuating member is rotated, and means for rotating the brake-actuating member only when the driving-member is rotated backward, substantially as set forth.

(4.) In a press of the class set forth, the combination with a carrier and a stamp or die below same of an elastically held inking-roller such as 25, swinging-arm such as 29, pinion such as 33, sector such as 35, spring-rod such as 36, and tappet such as 38, with or without stop-pin such as 40, substantially as described and explained, and as illustrated in the drawings. (5.) In a press of the class set forth, the combination with the stamping and marking mechanism of a base or abutment adapted to adjust its contour to suit the article to be stamped or marked, and to be fixed in such adjustment, substantially as described and explained. (6.) In a press of the class set forth, the combination with a fixed base of an adjusting base or abutment consisting of a casing such as 42, pivoted links such as 46, 47, and 48, springs such as 50 and 51, clamping-plate such as 54, and screw such as 55, with or without shaped spring-piece such as 44, and with or without protecting band such as 52, substantially as described and explained, and as illustrated in the drawings.
