CHARLES A. LUNDGREN, OF DAYTON, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE NATIONAL CASH REGISTER COMPANY, OF DAYTON, OEIO, A CORPORATION OF OHIO, (INCORPORATED IN 1906.)

CASH-REGISTER.

T 0 all whom it may concern:

Be it known that I, CHARLES A. Lonn- GREN, 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 Cash-Registers, of which I declare the following to be a full, clear, and exact description.

This invention relates to cash registers and has for its object to provide a machine especially for use in canceling so called bundle tickets or delivery slips.

In many commercial houses, for example, a sale slip is made out in duplicate, one copy being filed and the other copy being given to the customer who thereupon takes the purchase away with him or her. This system in practice is fairly satisfactory in cases where the customer does not desire the bundle delivered by the store but in cases where a delivery is to be made as by wagon, opportunity is given to the clerks to defraud the proprietor. This duplicate slip system is also used in connection with a well known type of cash register in which the machine prints the amount of the sale in two places on a slip which is then severed into two parts, one of which is retained in the machine as a voucher, the other being ejected and serving as a receipt. In the use of such nachines in connection with a sale for immediate delivery the amount received must be added in on the machine in order to print on the slip, without which the bundle will not be wrapped. In the case of a sale with future delivery an operation of the machine is made and the sale slip attached to the bundle which is then taken to a room to be wrapped, and in such cases some means of authorizing the wrapping and sending out of the package must be provided.

My invention aims to provide means for authorizing such wrapping and delivery and to this end I employ a delivery slip or bundle ticket longer than the usual sale slip, which is adapted to have printed thereon such matter as the word Paid and the date or other desired matter. The portion of the slip bearing this matter may be de tached and pasted or otherwise attached to the bundle, and will be understood as authorizing its delivery.

In particular this invention aims to im- Specification of Letters Patent.

Serial No. 305,316.

prove the machine shown in application bearing Serial. Number 160,t16, filed June 6, 1903, by Thomas Carroll. The machine shown in said application is designed to make two printing impressions on a sale slip, one part. of the slip being retained in the machine after the impression is made and the other part being taken from the machine after printing.

For use in connection with future delivery sales I provide a longer bundle ticket or delivery slip than the usual sale slip and means are provided for marking this slip with a record of any desired matter 6. g. the word Paid and the date. The machine includes an extra printing device so located as not to operate on the usual sale slip as such slip is not long enough to reach the extra printing device but when a longer bundle ticket is inserted in the machine the above stated additional impression will be made.

\Vith these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form of embodiment of which is hereinafter specifically described with reference to the drawings which accompany and form part of this specification.

Of said drawings: Figure 1 represents a vertical transverse section through the machine and cabinet showing the operating cam and the main printing table. Fig. 2 represents a vertical transverse section through the machine and cabinet showing the vertical shaft and its operating mecha nism. Figs. 2 2 and 2 are detail views of the auxiliary printing device and Fig. 3 represents a rear view of part of the machine with the cabinet partly broken away.

The main revolution shaft 10 is rotated by any suitable driving mechanism and receives one complete revolution at each operation of the machine in the direction of the arrow in Fig. 1.

Fast to ,the shaft 10 is a disk 11 in which is formed a cam groove 12 adapted to engage an anti-friction roller 13 mounted on a reciprocating lever 14. The lever 14 is so formed as to straddle the shaft 10 and has an upward and rearwardly extending arm 15. Extending laterally from the arm is a rack 16 which engages a pinion 17 mounted on a vertical shaft 18 which is given a partial revolution at each operation of the machine as will be explained later on. The other end of the lever 14 is pivoted to an arm 19 which is in turn pivoted to the frame work of the machine.

As seen in Fig. 3 the hub of the pinion 17 is provided with a pin 20 which extends into a groove 21 in the shaft 18. This makes it possible for the shaft to receive a reciprocatory movement in addition to and withoutinterfering with its revoluble movement. This reciprocatory movement is produced by the following mechanism: Fast to the shaft 10 is a disk 25 in which is formed a cam groove 20 adapted to operate upon an anti-friction roller 27 mounted on an arm extending upwardly from a lever 28. The lever 28 is pivoted on the frame work of the machine at 29 and has at its other end a pin 30 adapted to engage bet-ween two disks 31 fast to the lower end of the shaft 18. The above mentioned disks 11 and 25 and others of the same kind will hereafter be men tioned as box cams. The relative timing of these two movements of the shaft 18 will be described later on.

Removably secured to the upper end of the shaft 18 is a frame 35 which contains the auxiliary printing wheels 36. These printing wheels 36 have suitable numbers and characters for printing the date equally distributed around their periphery and are held in printing alinement by suitable spring pressed alining plungers 37 engaging toothed alining wheels 38 of which there is one fastened to each printing wheel.

The hub 39 of the frame 35 is held in position against a collar 10 (which is secured to the shaft 18) by a thumb screw 41 and is prevented from turning on said shaft by a tongue and groove 42 between said hub 39 and the collar stO. In the forward end of the frame 35 is mounted a spring pressed. plunger 43 which has a flange M- at its upper end to limit its movement in one direction. In the normal position of the frame 35 (see Fig. 2) the plunger 13 rests on the cabinet of the machine with its spring contracted but as soon as the frame is raised the plunger will assume a position like that shown in Fig. 3. Fastened to the under side of the frame 35 is a plate 45 having the word Paid engraved thereon so as to print said word in connection with the date.

In a recess in the cabinet there is an inking pad 46 upon which the auxiliary priut ing wheels 36 and plate 45 rest when the frame is in normal position. This supplies the wheels and plate with ink.

The impression platen 50 is pivoted at 51 to the framework of the machine and has an impression block 52 made of rubber or other suitable material. A spring normally tends to draw the platen down but is normally prevented from doing so, (see Fig. 3) by a spring pressed pawl 53 which ongages a laterally projecting pin 54lmounted on the platen 50. This pawl 53 is pivoted at 56 and has a foot 57 which is operated upon by a downwardly projecting foot 58 of a tripping pawl 59 to trip the pawl 53 from the pin 54. This will allow the platen 50 to be drawn downwardly by the spring and will prevent any printing as the impression block will then be below the printing line. The pawl is provided with a pin 60 which contacts with the framework of the machine to limit its downward movement. A spring (31 is coiled around the hub of the pawl and tends to force said pawl into locking engagement with the pin 5 of the impression platen 50. The pawl 55) is operated upon by the plunger 4-3 in the following manner.

If a delivery slip (which is longer than the regular sale slip) is inserted into the machine it will extend over the impression block 52 and also over a. hole 2 in the cabinet of the machine. When the machine is operated the shaft 18 will first be lifted to raise the auxiliary printing mechanism from the inking pad is. The shaft 18 will now be rotated to bring said printing mechanism into the position shown in l ig. 3 and will then be lowered to print on the delivery slip. The slip being in position will receive the printed impression because the paper over the hole prevents the plunger 43 from entering said hole and operating the pawl 59 to trip the pawl 53 from engagement with the pin After the printing is done the shaft 18 is again raised and then rotated back to normal position, the last movement being to lower the auxiliary printing mechanism so the type wheels 36 and the plate 37 will rest on the inking pad 1 The spring of the plunger is light enough to allow the plunger 43 to operate without breaking through the paper.

If there is only a regular sale slip in the machine the following will result: The sale slip is not long enough to extend over the impression block 52 and the hole (32 therefore the plunger .43 will (upon the operation of the maehine)operate the pawl 59 to trip the pawl 53 from engagement with the pin thereby allowing the impression platen 50 to be drawn downward by its spring 55 until the pin 5 1-v strikes the framework of the machine. It will be readily un derstood that in this position the auxiliary printing will be rendered ineffective.

The impression platen 50 is restored to its normal position by the following mechanism. Mounted loosely on a. shaft is a pawl 71 having a downwardly extending arm 72 and an upwardly extending shoulder 73. A stop pin 74 limits the movement of the pawl 71 in one direction. A suitable spring (not shown) normally tends to draw the pawl 71 against the pin 74. Mounted on the box cam are two pins 76 and 77 which strike the forward side of the arm 72 of the pawl 71 to lift the shoulder 73 upward against the under side of the impression lever 50 to restore the same to normal position. The pin 76 first acts on the arm 72 to restore the platen 50 if it has been accidentally or otherwise tripped and the pin 77 acts on said arm to restore said platen after the printing operation is completed. The main printing wheels are set to print the different amounts by mechanism described and shown in the above mentioned pending application. The main printing platen or table 91 has a downwardly extending arm 92 provided with an anti-friction roller 93 which is operated upon by a cam groove 94 of the box cam 80 to vibrate the table 91 up and down twice to make two impressions on the paper strip. Between these two impressions the paper slip is fed forward by the following mechanism. A cam groove 95 is formed in the box cam 25 and acts upon an anti-friction roller 96 mounted upon one end of a bell crank lever 97 pivoted on a stub shaft 98 to reciprocate a rack bar 99 which meshes with a pinion 100 mounted upon one end of a shaft 101. The shaft 101 is mounted in the table 91 and has mounted thereon a feed roller 102. A pressure roller 103 mounted on a lever 104; is so arranged as to come into contact with the feed rollers at the proper time. The above mentioned main printing mechanism and feeding mechanism is fully described and shown in the above mentioned pending application to which reference may be had for a more detailed description. The operation of the machine and the relative timing of the different mechanisms will now be de scribed.

Let us suppose that the main printing wheels 90 have already been set to their printing position and that a delivery slip has been inserted to extend over the main printing table 91 and also over the impression block and the hole 62. The main shaft 10 will rotate in the direction of the arrow (see Fig. 1) and the following will result. First the arm 28 will raise the shaft 18 so as to lift the auxiliary printing mechanism free from the inking pad 416. During this raising of the shaft 18 the main printing table 91 has also been raised to print the amount previously set up by the machine. About the same time that this printing is done the pin 76 will strike the arm 72 of the pawl 71 and will restore the impression platen 50 if it had been accidentally or otherwise tripped before the machine had been started. Immediately after the shaft 18 is raised the arm 14 will vibrate to revolve the shaft 18 and bring the auxiliary printing mechanism into a position as shown in Fig. 3. Next the main printing table 91 will be lowered slightly and the paper delivery slip will be fed forward by the feed roller 102. After this feeding forward of the slip takes place the main printing table 91 is again raised to print the amount on the slip a second time after which the table 91 is lowered to its normal position. While the table 91 is being raised to print the second time the shaft 18 is lowered by the arm 28 to bring the auxiliary printing mechanism against the slip to print the word Paid and the date. It will be clearly seen that if there is no paper over the hole 62 that the platen 50 will be released as previously explained. The shaft is now raised again and rotated back to its normal position after which the pin 77 will strike the arm 72 of the pawl 71 and raise the shoulder 72 to restore the impression platen 50 to its normal position. At the very last part of the revolution of the shaft 10 the shaft 18 is lowered to bring the auxiliary printing mechanism against the inking pad 46. 7
