CASH REGISTER.

SPECIFICATION forming part of Letters Patent No. 697,982, dated April 22, 1902.

I Application filed March 2,1900. Serial N0. 7,139. (No model.)

To (tZZ whom it may concern:

Be it known that I, JOSEPH P. GLEAL, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Oash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to improvements in IO cash-registers, and has more particular relation to improvements in machines of the class patented to J. H. McCormick October 27,1896,

The object of the invention is to provide improved devices in a cash-register for looking the keys while the cash-drawer is open.

In the accompanying drawings, forming part of this specification, Figure 1 represents a vertical section,partly broken away,through a machine embodying my invention. Fig. 2 represents a similar View with the parts in a different position. Figs. 3 and 4. and also Figs. 5 and 6 represent, respectively, similar views to Figs. 1 and 2 of modified forms of my invention.

In the aforesaid drawings, 1 represents the frame of the machine; 2, the keys; 3, the cashdrawer, and 4 the detent.

The construction and operation of the keys,

o cash-drawer, and other parts of the machine are substantially the same as disclosed in the aforesaid patent, and I will therefore refer to the same for a detail description of such parts. As all the banks of keys and their 3 5 respective detents and cooperating parts are similar I will describe one group only, as this description will suffice for all.

Each segmental detentd is pivotally mounted upon the main transverse shaft 5 of the machine and is provided with a series of hook projections 6, formed with locking-notches 7. These projections cooperate with the keypins 8 substantially as described in said patent, except that the detent is so mounted that it may be moved to bring the notches 7 into alinement with the pins 8. and thus lock the keys against operation. The segment 4 is further provided with a pendent rigid arm 9, which cooperates with a pivoted bell-crank 5o lever 10, mounted on the main frame. This latter lever is limited in its movements in one direction by a pin 11, mounted on the main frame, and is arranged to engage a bevel-ended flange 12, mounted on the drawer 3. When the parts are in the position shown in Fig. l, the flange 12 holds the bell-crank lever up, in which position, by its engagement with the arm 9, it holds the detent in its normal position, with the locking-notches 7 out of alinement with the pins 8. When the parts are in this position, the keys are free to be operated in the usual manner to raise the detent, so that the pin 8 of the operated key will pass under its respective hook to retain the key in its depressed position. WVhen the cash-drawer is released and forced out of the .casing, as described in said patent, the flange 12 passes forward from under the bell-crank, and the latter is thus left free to descend until it is arrested by the pin 11. This action releases the arm 9 and its detent and permits the latter to drop until the notches 7 come into alinement with the pins 8, and thus lock the keys against operation. Any attempt now made to operate a key will simply result in its pin 8 becoming seated in its respective notch 7, and as the pressure will be radially inward toward the fulcrumshaft 5 the detent will not be moved, but will simply stand in the path of the pin. As long as the drawer remains open the parts will remain in the positions shown in Fig. 2, with the keys all locked; but when the drawer upon being closed reaches its final closing movement the bevel end of the flange 12 engages the bell-crank lever and forces it back to its original position, which action moves the detent to the position shown in Fig. 1, thus leaving the keys free to be operated.

In the form of my device shown in Figs. 3 0 and 4 I provide the detent 4 with apendent rigid arm 15, the lower end of which extends to the rear of the vertical plane of the journalshaft 5. This arm cooperates with a bevel-ended flange 16, mounted in the top of 5 the cash-drawer. In this modified form'of my invention the detent is formed with arigid extension 17, having a V-notch 18 formed therein and into which projectsan aliningbolt 10. This boltis suitably mounted on the main frame and is springpressed to force its wedge-shaped end normally into the bottom of the V-notch, and thus normally holds the detent in the position shown in Fig. 3, in which the keys are free to be operated, as in Fig. 1. IVhen in this normal position, the detent is free to be either raised or lowered. If raised by the regular action of the keys, the lower end of the arm 15 passes downward and forward in an arc in front of the forward end of the flange 16 and then returns to its normal position (shown in Fig. 3) as the keypin passes into the notch of its respective hook 6. Now when the cash-drawer is re leased and opened, as described in said patcut, the forward bevel end of the flange 16 engages the lower end of the arm 15 and rocks the same upward and rearward, which action brings the detent down against the tension or the spring-plunger 19 into-the position shown in Fig. 4, and thus the notches 7 are brought into alinement with the pins 8 and the keys locked against operation in the manner aforesaid. The keys remain thus looked as long as the flange 16 remains under the arm 15 to hold it up; but when the cashdrawer is closed the arm 15 is allowed to again drop and assume its normal position under the stress of the spring-plunger 19, and thus unlock the keys. As long as the cash-drawer remains open and also while it is being opened or closed the arm 15 rests upon or rides along the flange 16, and thus holds the detent in its lower key-locking position.

In the modified form of my invention shown in Figs. 5 and b the drawer-flange is omitted and the detent moved by devices contacting with the rear of the drawer. The detent in this form is similar to the detent shown in Figs. 1 and 2; butin lieu of the bell-crank 10 for operating the arm 9 I employ a pivoted lever 21, mounted on the main frame, so as to engage said arm substantially in the same manner as the bell-crank. A pivoted lever 22 is also mounted on the main frame in such position as to be engaged by the rear flange or wall of the cash-drawer. This latter lever is connected to the lever 21 by a pivoted link-bar 23 and is limited in its movements by a pin 2t, also mounted on the main frame. When the cash-drawer is closed, the parts are held in the normal position shown in Fig. 5, with the notches 7 out of alinement with the pins 8 and the keys free to be operated. Now when the cash-drawer is released and opened the lever 22 is relieved of any pressure, and thus also leaves the lever 21 and the detent-segment free. When so released, the detent will drop by gravityinto the position shown in Fig. 6, and thus lock all the keys against operation. As long as the drawer remains open the lever 22 will remain resting against the pin 21 in the position shown in Fig. 6; but upon said drawer being closed its rear wall will again engage and operate said lever and raise the detent to the position shown in Fig. 5, when the keys will again be free to be operated.

I do not care to confine myself to any particular form of registering or indicating devices cooperating with the keys, but have simply referred to the form shown in the aforesaid patent for an illustration of the application of my invention.

Other modifications will be readily apparent. For example, as shown in the drawings, there is a notch 7 formed on the end of each of the hooks b of the detent-plate. My invention would be equally operative if the ends of the books were simply straight surfaces instead of the notches, as described.

An important feature of my invention consists of the fact that when the drawer is open the detent-plate moves or is moved from normal operative position to an abnormal position, in which it prevents operation of the keys.

In connection with my present application attention is directed to my copending application, Serial No. 7,201, filed March 3, 1900.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cash-register, the combination with a series of keys, of a detent having lockingnotehes for the same, a cash-drawer, and means for holding the detent so that its notches are out of alinement with the keys when the drawer is closed and in such alinement when the drawer is open.

2. In a cash-register, the combination with a series of keys provided with pins, of a detent having locking-notches for said pins, a cash-drawer, and means intermediate the cash-drawer and detent whereby when the drawer is closed the looking-notches are held out of alinement with the pins but when the drawer is opened are moved into such alinement.

3. In a cash-register, the combination with a movable detent formed with lookingnotches, of a series of keys radially mounted in respect to said detent so that when operated they become seated in said notches and exert a pressure directly toward the point of support of said detent and are thus locked against operation and means for moving the detent.

4. In a caslrregister, the combination with a pivoted detent having a series of lockingnotches, of a series of radially-arranged keys adapted when operated to become seated in said notches and exert a pressure toward the pivot of the detent, a cash-drawer and means intermediate the drawer and detent for adjusting the latter to bring the notches into the paths of the keys when the drawer is opened.

5. In a cash-register, the combination with a series of keys provided with laterally-projecting pins, of a pivoted detent having bevel projections formed with locking-notches and arranged to be engaged by said pins, a cashdrawer, and means intermediate the cashdrawer and detent whereby when the drawer is closed the locking-notches are held out of alinement with the pins but when the drawer is opened are moved into such alinement.

6. In a cash-register, the combination with a series of keys, of a detent having key-locking notches and a pendent arm, and means operated by the cash-drawer and engaging said arm to move the detent so that the notches are out of locking position when the drawer is closed andin locking position. when the drawer is open.

7. In a cash-register, the combination with a series of keys, of a detent arranged to be engaged by the keys and formed with retaining-notches and key-locking notches, the latter normally out of the paths of the keys, a cash-drawer and means intermediate said drawer and detent whereby when the drawer is opened the detent is moved to bring the locking-notches into the paths of the keys to lock the latter.

8. In a cash-register the combination with a series of keys, of a detent having key-locking notches which are normally out of the paths of the keys, a cash-drawer, a pivoted lever arranged to be operated by said cash drawer and means intermediate said lever and the detent whereby the latter is operated to bring the notches into the paths of the keys to lock the same.

9. In a cash-register, the combination with a series of keys of a detent therefor having locking-notches which are normally out of the paths of the keys and also a pendent arm, a cash-drawer, a pivoted lever engaging said arm, a pivoted lever arranged to be operated by the cash-drawer and a pivoted link connecting said levers, the construction being such that the notches are brought into the paths of the keys when the cash-drawer is opened.

10. In a cash-register, the combination with a series of keys having laterally-projecting pins, of a pivoted detent having lockingnotches which cooperate with said pins, a pendent arm mounted on said detent, a cashdrawer, a pivoted lever arranged to be e11- gaged by the rear wall of said drawer, a pivoted lever engaging the pendent arm, and a pivoted link connecting said levers.

11. In a cash-register, the combination with a pivoted detent having radial projections formed with looking-notches, of a series of radially-arranged keys adapted to cooperate with said projections and locking-notches, a cash-drawer and means intermediate said drawer and detent whereby the notches are held in alinement with the keys when the drawer is open.

12. In a cash-register, the combination with a movable detent having bevel-face projections formed with locking-notches and retaining-notches, of keys having projecting pins which cooperate with said projections and notches and independent means for moving the detent to bring the locking-notches into the paths of said pins and thus prevent the depression of the keys.

13. In a cash-register, the combination with a movable detent formed with bevel-face projections having locking-notches, of a series of keys arranged to engage said projections and thus move the detent, and independent means for moving the detent to bring the locking-notches into the paths of the keys and thus prevent the latter from being depressed.

14. In a cash-register, the combination with a series of keys, of a movable member formed with locking-notches and arranged to be operated by the movement of any key to allow the keys to become latched thereto, and a cashdrawer directly engaging said member to move it and bring the locking-notches into alinement with the keys to prevent the depression of the latter.

15. In a cash-register the combination with a series of keys, of a sliding detent, a series of projections arranged to retain an operated keyin depressed position, said detent being given a limited movement whenever a key is depressed, of a cash-drawer and means controlled thereby for moving the detent into position to lock the nnoperated keys of the series when the cash-drawer is opened.

16. In a cash-register the combination with a series of keys having lateral projections or pins 9, of a cooperating detent arranged to retain the operated keys in depressed position, a cash-drawer and means for moving the detent into position to lock the keys when the cash-drawer is opened.

In testimony whereof I atfix my signature in the presence of two Witnesses.

JOSEPH 'P. OLEAL.
