Title: Improvements in Brake Apparatus for Railway Wagons and other Vehicles.
Inventor: SPENCER ALEXANDER
Filed: 1901-10-26
Granted: 1902-10-23
Abstract: 21,566. Spencer, A. Oct. 26. Brakes, hand. Relates to either-side brake apparatus of the type described in Specifications Nos. 12,028 and 16,263, A.D. 1901. In the present case, a combined pawl and catch 13, 14, connected by an arm 15 and pivoted to the inner side of the loose brake lever A, co-operates with a tumbler 17 pivoted to a lug 5<a> on the hand-lever 5 fast on the shaft 1. With the brakes in the "off " position, as in Fig. 1, on raising the lever 5 the lower end 17<b> of the tumbler 17 engages the tail 15<a> of the arm 15, and moves the catch 14 from the notch 12, as shown in Fig. 5. If the levers 5, A are dropped, the brakes are applied, the stress being transmitted by the stop 7 on the lever A, and the pawl 13 engages the rack 11 to hold the blocks "on." On lifting the lever 5, the tumbler 17 passes the arm 15, while the lever 5 engages the catch 14, trips the pawl 13, and thus releases the brake gear and lifts the lever A by means of the catch, which finally engages the notch 12, and the brakes are then held " off." To prevent the lever A from being jerked free accidentally during shunting, the tumbler 17, Fig. 7, has a projection 17<c> which engages a notch 15<a> in the arm 15, while the catch 14 has a projection 14<a> adapted to engage the notch 12<a> in the guide 9. In the modification shown in Fig. 8, the tumbler 17 is so arranged that, when the brakes are "off," the portion 17<a> rests on the top of the connecting-arm 15, and the end 17<b>, which has a lateral projection 18, comes under the end of the lever A, so that, on raising the lever 5, the lever A is raised until the top of the pawl 13 strikes the inclined surface 19 and moves the catch 14 free from the notch 12. On applying the brakes, as the pawl 13 moves into engagement with the rack 11 its lower end 14<a> strikes the projection 18 and moves the end 17<b> of the tumbler clear of the lever A.

Granted: 1903-07-23
Abstract: 8066. Marks, G. C., [Superior Match Co.]. April 7. Matches, making. In machinery for filling the plates employed in dipping match splints, the cylindrical screen or hopper with perforated walls 2, Fig. 1, containing the splints, is rotated intermittently by the pawl 7, actuated by the links 11, 6, the lever 9, and the eccentric 12 on the shaft 13, which is geared to the main shaft 14. The splints drop on to an inclined race-board 21, vibrating on pivoted supports 218 operated by eccentrics 217 keyed to shaft 14, and pass lengthwise along its channels. There are steps in the channels, and a grating to sift out broken splints and slivers. The lower ends are channeled to feed the splints into the hoppers, Fig. 8. The upper and lower partitions 31, 35 between the hoppers swing on pins 32, 36, and carry inclined and alternating wings 38, 39. Hanging sections 33 swinging on pivots 34 allow of equalization of the contents of adjacent hoppers, and a flexible blade 37 prevents the splints from jamming at the bottom. A shaft 44, Fig. 1, driven by chain gearing from the main shaft 14, actuates the rocking shaft 43 by means of an eccentric 46, and through the levers shown vibrates the upper and lower sections of the partitions, so as to work the splints downwards. The feed-plate 60, Fig. 13, beneath the hoppers, is reciprocated parallel to the raceboard by an eccentric on . the shaft 13, Fig. 1, and upon this plate the splints from the hoppers lie in grooves. A lower plate 65, also actuated by the eccentric, carries blocks 64, which rise in slots at the back of the grooves when the feed-plate begins to move forward. The feed-plate moves until the projecting edges of the splints are lodged in holes in a vertical dipping plate 73. The blocks then sink, and, on the back stroke, a stop pushes forward, along the grooves, the splints which have fallen from the hoppers. The dipping- plates 73 are carried upwards by pegs 171 on the chain 19 driven by eccentric 15 and ratchet-wheel 18, and are thrown off on to the roller 92 by the curved guard 90. Reserve plates are kept in position on the ledge 80 by the spring 81.
