Abstract: 678. Fell, J. C., [Felbel, J.]. Jan. 10. Type-writers.-Relates (1) to means for varying the leverage on the type-bar throughout its stroke, so that a greater force is exerted on it when starting than during the remainder of its movement, and (2) to means for varying the " touch " of the machine to suit different operators. The type-bars 6 are pivoted on a common fulcrum rod 7, carried by a segment 9 which has a rising and falling movement for change of " case." Springs 18 normally hold the type-bars against the segmental pad 14. Links 22 connect the type-bars with bell-crank levers 25 pivoted at 26 to the key levers 27 and provided with slots 29 engaging with a common fulcrum rod 30. Springs 32 normally hold the key levers upward against a pad 37. The rear ends of the key levers are curved at 39 so as to form a surface which creeps or rolls along a fulcrum plate 38 when the key lever is depressed, thus producing a continuous shifting of the fulcrum away from the bell-crank lever 25. The curvature of the working edge 39 is preferably not uniform, but diminishes towards the rear end. The key levers are held in place by a comb-plate 44 and a rod 41 engaging in notches 40. The escapementdog rocker 55, which may be provided with the usual adjustable controlling-spring, is connected by a lever 51 and links 50 with a universal bar 49 placed beneath the key levers near the bell-crank lever 25. The fulcrum plate 38, which crosses the rear ends of all the key levers, is supported at its ends on two fixed bars 60 curved in the same manner as the key levers. A spring 66 holds the fulcrum plate down on the bars 60, and by adjusting the thumb-screw 62 it can be rocked on the bars so as to shift the initial fulcrum point, and vary both the initial leverage on the type-bar and the depth of the key stroke. In Fig. 14, a modified form of construction is shown applied to an " understroke " machine. The key levers 27<b> are provided with slots 71 through which passes the fulcrum rod 68. The leverage is varied by shifting the rod 68 by means of the arms 69, rock-shafts 70, and notched link 72. Controlling-springs 32<a> act upwardly on the key levers.

Title: Improvements in Barrel Fillers
Inventor: ENZINGER KARL
Filed: 1902-02-03
Granted: 1903-01-01
Abstract: 2731. Enzinger, K. Feb. 3. Filling with liquids.-In apparatus for filling barrels with beer under pressure, to prevent foaming, the opening and closing of the filling-valve is effected automatically, and it is also arranged that the liquid in the gauge glass will, for any size of barrel, make up the deficiency due to the withdrawal of the filling-pipe. The liquid is conveyed from the underside of a vessel a to the filling-pipe c which moves within a socket d having a suitable packing to close the bunghole, the pipe c and socket d being moved to and from the barrel by pistons working in concentric cylinders e, the pipe c being connected to its actuating piston-rod h by a yoke i and crosshead k, and the socket d being connected by rods f. The pipe c is automatically opened and closed by a valve g having a rod l to which is pivoted a lever m ; this lever supports at its other end a disc o actuated by a spring p, and is connected with the yoke i by a link n. Compressed air being admitted to the barrel by a pipe leading from the top of the vessel a to the gauge b, the socket d is lowered into position. The pipe c which is closed by the valve g is then caused to descend, and in its descent the lever m abuts against a stop q, and thus the rod l is moved relatively to the pipe c and the valve is opened,. the valve being again automatically closed by the spring p when the pipe c is raised. To ensure that for any size of barrel the liquid in the gauge b will be sufficient to make up the deficiency, a modification is used in which the lever m, when actuated by the stop q to open the valve, is held by a spring catch, and is so retained until released by stop-brackets when the pipe c is raised to a sufficient height.
