For the purpose of arresting a partially-operatedkey if released, and preventing it being restored to normal position until ithas been first operated to its full extent, there is an arrester applied to the bar J to arrest and hold it and the key or keys, which may be locked to it` in any position to which it may be moved less than the full limit of movement given it by the complete operation of the key. As shown in Fig. 1, this arrester consists of a rack e, secured to one of the side arms J of the bar and cti-operating with a pawl which engages the rack as the bar J is lifted and becomes disengaged therefrom when thekey and bar have reached their limit of upward movement. rlhis pawl f is a shoulder or projection on the front side of t-he lower vertical arm g of a bell-crank L, pivoted to the frame-work at 7i, andthe weight of whose other arm t' normally presses the pawlf against the rack e. As a keyis operated and the barJ lifted, the pawl f slips over the teeth of the rack e and engages therewith if the bar and key are released. Just as the key reaches its limit of upward movement a pin j on the side of the bar J strikes the arm `i of the bellcrank L and throws its arm g and pawl f away from the rack e, as shown by the dotted lines in Fig. l. To hold the rack and pawl out of engagement while the key and bar J are returned to normal position, there is a latch M, pivoted to the frame work at k, and having a forward weighted end and an upwardly-euiwed nose l at its rear end. The nose of this latch is of such width that its inner edge extends beneath the edge of the bar J or its flange d, so that when the bar J is in its normal position it presses it down and holds it in the position shown in Fig. 1. As any key is operated, the bar J is lifted off the nose of the latch, which is thereupon thrown upward by the gravity of its weighted forward end, which drops against a pin projecting from the frame-work, as shown by the dotted lines. rlhe latch having assumed the position shown by the dotted lines, when the key and bar J reach their limit of upward play, and the pin j strikes the arm 'L' of the bell-crank L, the lower end of the arm g, in assuming the position shown by the dotted lines, flips over the nose of the latch,and is prevented by the latter from falling back into engagement with the rack e as the key and bar J are returned to norma-l position. Just as they reach that position, however, the bar J again engages and presses down the nose of the latch to the position shown by the solid lines, whereupon the arm g and pawl f fall back against the rack e, ready for the operation of another key.

It results from this construction and arrangement of the parts that whenever any key is substantially displaced from normal position it cannot be returned th ereto until it has been operated to its full extent, and that until it is so operated and returned to normal position all the other keys remain locked. In the construction shown and described in the application before referred to there was provided, for the purpose of locking the unoperated keys, a separate locking-bar extending across the rear ends of the keys and actuated from the bar J to move over the unoperated keys and lock them whenever any key was operated, and it has heretofore been necessary to employ such separate locking-bar; but by providing the keys with the slotted lugs having the curved forward sides adjacent to the bar J the lugs which before served merely to lock the operated keys to the bar now serve the double purpose of locking the operated keys to the bar and locking the unoperated keys from operation until the operated key or keys have been returned to normal position. It is also desirable in this class of machines to prevent the operation of the keys while the cash-drawer is open, and we have devised novel and simple means for this purpose. (Shown in Figs. 2 and 3.) Loosely pivoted to the frame-work at m is a pendent arm N, whose lower end is connected to the forward end of a rod O, extending rearwardly through a guide in the slotted guide-plate l. The rear end of this rod is bent at right angles to the horizontal portion and extends downward through a slot in the base upon which the frame-work rests into the drawercompartment. Its lower end carries a setscrew n, whose front end bears against thc rear side of the drawer C when the latter is closed. Projecting from the upper side of the rod O, in rear of its connect-ion to the arm N, is a plate 0, whose upper end is bent inwardly and extends through the pat-h of the end of the flange (l, so that when the lrod O is moved forward the upper bent end of the plate o will move over the edge of the flange d and lock it and the bar J down, if in their normal position; or, if they are elevated, it will move beneath the flange d and prevent the resetting of the bar J and the key or keys which may be locked to its flange d. A coiled spring p, secured at its forward end to the frame-work and at its rear en d to the rod O, tends to pull the latter forward. lVhen the drawer C is closed, its rear side, bearing against the end of the screw fn., holds the rod O against the pull of the spring p in the position shown in Fig. 1, so that the bent plate 0 is in the rear of the flange d, and the latter is free to be lifted by the operation of a keyA lVhen any key is operated and the drawer thereby released and propelled from its compartment by the spring P at its rear end, the springp immediately pulls the rod O forward to the position shown in Fig. 3, so that when the key is released its descent is arrested by the flange d, to which it is locked, striking the bent plate o. In this position of the parts not only is the operated key held from rcturning to normal position, but the flange d,

extending across the front faces of the lugs K of all the unoperated keys, locks-them from operation. The machine is therefore rendered inoperative until the cash-drawer is closed, whereupon its rear side, striking the front end of the screw n, throws back the rod O to the position shown in Fig. 2, thereby movingr the plate 0 from under the flange d and permitting the latter and the operated key to be reset and unlocking all the unoperated keys.

For the purpose of throwing out Of Operation the mechanism just described,whenever it is desired to permit .the machine to be operated while the cash-drawer is open, we pivot to the frame-work at q a bent lever r, whose lower end bears against the arm N, and takes into a notch s when-ever its upper end is.

pulled forward, and thereby holds the arm N and rod O in the position shown in Fig. 2, so that they cannot be pulled forward by the spring p when the cash-drawer is released and propelled from its compartment.

Having thus fully described our invention, we claiml. In a cash register and indicator, the combination Of a series of operating-keys, each provided with a slotted lug having a curved forward side and a vibrating bar extending across said keys immediately in front Of their slotted lugs, and its rear edge moving in the arc of a circle, topwhich the curved faces of the slotted lugs conform, whereby upon operating any key it becomes locked to the vibrating bar, and the latter locks all the un-' operated keys from operation, substantially as and for the purpose described.

2. In a cash register andindicator, the combination of a series of pivoted operating-keys, each provided on its upper side with a slotted lug having a curved forward side and a vibrating bar extending across said keys,and having a flange on its lower rear side immediately in front Of the slotted lugs, the rear 3. The combination of the operating-keys D, provided with the slotted lugs K, having the curved forward faces, the vibrating bar J, having the fianged moving in the arc of a circle conforming to the curve of the forward faces of the lugs K, and an arrester applied to said bar to prevent it being reset after being moved by the partial Operation of a key until it is given its full movement by the full operation of a key, whereby upon operating any key it becomes locked to the bar J and cannot be reset until operated to its full extent, and whereby all the unoperated keys are held locked from operation by the bar J until the operated key has been returned to normal position, substantially as and for the purpose described.

4f. The combination of the keys D, having the slotted lugs K, the vibrating bar J, having the flange d, the arm N, the rod O, having the bent plate o, `and the drawer C, substantially as and for the purpose described.

'5. The combination of the keys D, having the slotted lugs K, the vibrating bar J, having the flange el, the arm N, the-rod O, having the bent plate 0, the drawer O, and the lever o", substantially as and for the purpose described.
