PRINTING AND EJECTHNG MECHANISM FOR CASH REGISTERS Application March 7,
1934, Serial No. 714,478
in Germany March 13, 1933 10 Claims.
This invention relates to improvements in the type of cash register often referred to as an` accounting machine or posting machine and illustrated and described in Letters Patent of the United States No. 1,747,397, issued February 18,
1930, to B. M. Shipley.
Generally speaking, it is an object of this invention to provide an accounting machine with means to positively eject record material, said ejecting means also serving as a means for locating record material in relation to the printing mechanism.
A more specific object is to provide the machine of this invention with .a reciprocating ejecting bar that extends the full width of the type carriers and impression mechanism and travels across the printing point to positively remove insertable slips from between the type carriers and the impression mechanism.
Another object is to supply novel means to align the edge of the insertable siip with the locating ejecting member.
With these and incidental objects in view, the invention consists ci' certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawing which accompanies and forms a part of this speciiication.
Of said drawing:
Fig. l is a front elevation showing the mechanism of this invention.
Fig. 2 is a plan View as observed from above illustrating a portion of the impression and ejecting mechanisms.
General description 40 The impression hammer of the instant machine is actuated twice in each machine operation to first print various amounts and data upon an insertable record slip and then to duplicate this impression upon an audit strip which is rcv tained in the machine. The web of the audit strip is unwound from the receiving roll and threaded around various guide rolls past the platen of the impression hammer, thence around the impression hammer, after which it is wound 510 upon a receiving roll in the well known manner.
" A reversible inking ribbon passes between the web of the .audit strip and the type carriers.
Prior to releasing the machine for operation,
the record slip is inserted between the inking vrp ribbon and the web of the audit strip, which it will be recalled are interposed between the impression hammer and the type carriers. During machine operation initial movement of the impression hammer forces the record slip and the inking ribbon into contact with the type carriers to cause animpression to be made on said record slip. Immediately thereafter the record slip is ejected from the machine and the second movement of the impression hammer moves the audit strip into Contact with the inking ribbon and the type carriers to cause a duplicate impression to be made upon said audit strip.
n The usual slip ejecting mechanism consists of pairs of superimposed rollers or disks between which at the proper time the slip is gripped after which rotation of the rollers ejects the slip. With this type of ejecting mechanism the accidental or intentional insertion of a slip which covers the printing point but which is not wide enough to engage the ejecting rolls, would, upon machine operation, result in such a slip not being ejected after the first impression. Consequently the second impression would also be made upon the record slip thereby preventing a record of the transaction being imprinted upon the audit strip. It is very necessary that a duplicate record of all transactions be kept upon the audit strip, as this record is very important to the proprietor of a business establishment in checking the business over a certain period.
In order to prevent unscrupulous employees from inserting narrow strips of paper between the type carriers and the impression mechanism, thereby destroying the proprietors record, the instant novel ejecting mechanism was devised. This mechanism consists of a reciprocating bar which passes between the impression hammers and the type carriers immediately after the rst impression is made, and positively removes or ejects any material, regardless oi size, away from the printing point. This insures a recording of the transaction on the audit strip. The mechanism of this invention will now be described in detail.
Detailed description Calling attention to Figs. i and 2, transversing the machine from front to rear and journaled in a bracket secured to the machine base and the printer front and back frames is a printer y to an arm 31 secured on a shaft 3S, the forward plate 4B.
Secured on opposite ends of the shaft 38 are arms 4l and 42 having pivoted thereto, respectively, the left ends of symmetrical links 43 and 44. The right hand ends of the links 43 and 44, respectively, fit loosely on studs 45 and 46 secured in upturned ears 4'! and 49 of a slip locating and ejecting bar 49. The ears 4l and 48 of the bar 49 have in the inner surfaces thereof, parallel grooves 55 and 5l, which cooperate respectively with parallel rails 52 and 53 Aformed respectively on stationary and similar plates 39 and 54. Y
Pivoted at 55 is an impression hammer 56 with a platen 57 which is adapted to be rocked clockwise into contact with type carriers 53 loose on a rod 59 supported by the printer frames. EX- tending above the type carriers 58 is aslip table 60 having an opening il through which-the impression hammer d passes to Contact the type carriers 58. The impression hammer 55 is enclosed by a case 62, the right hand end of which is narrowed down and in cooperation with the slip table 69 forms a slip chute63 for guiding record material between the impression means and the type carriers. strip 64 is visible through a glass window G5 in the case 62.
From the supply roll the web of the audit strip 64 is threaded around the pivot point 55, thence around the guide roll 66 across the face or" the platen 5l, around a guide roll 6l, around the edge of a writing table $8 secured to the impression hammer 5l' and then wound upon a receiving roll (not shown). Opposite ends of the guide roll 6B are journaled in arms 69 and 19 secured on a shaft 'll rotatably supported by the plates 39 and 54. An extension 'i2 of the arm 19 is bent at right-angles to cooperate with a flat spring 'i3 secured to the impression hammer 56. The spring T3 urges the arm 'l0 clockwise, as viewed. in Fig. l, into engagement with a stop stud 14 secured in the impression hammer 55.
' The arm 'i3 by means of the shaft Il and the arm 69, urges the roller 68 clockwise, causing said roller and the audit strip t4 to yieldingly engage the upper edge of the ejecting bar 49. An inking ribbon passes around a guide roller 1.6, thence above the type carriers 58, and around a spring member 1l' secured to a guide plate lli.' The spring member il together with the ink ribbon 15 yieldingly engages the lower edge of the ejecting bar 49.
In use, the record slip is inserted Within the chute 63 and advanced until the edge thereof, guided by the roller 55 and the spring member 'Vl engages a V-shaped groove 'i9 in the right hand edge of the ejecting bar 49. This locates the record slip in relation to the printing mechanism. The first movement of the impression v hammer 235 forces the record slip, together with the ink ribbon 15, into contact with the'type carriers 58 to impress a record on said slip.
Immediately after this first impression is taken the groove 32 in the cam 3l in cooperation with the roller 33 rocks the bell crank 34, first in a clockwise direction, which by means of the link 35 also rocks the arm 3?, the shaft 38, and the arms 4l and 42 in a clockwise direction. Clockwise movement of the arms 4l and 42 by means of the links 43 and 44 moves the ejecting bar 49 horizontally toward the right, in which movement it is guided by means of the rails 52 and 53, in cooperation with the parallel slots in the The printing on an audit end ofl which is journaled in a printer front upturned ears of said ejlecting bar 49. This ini-f tial movement of the ejecting bar 49 positively ejects any record material, regardless of its length, from between the impression hammer 56 and the type carriers 58.
Before the second impression is made` the cam 3| returns the ejecting bar 49 to normal position, as shown in Fig. 1. Immediately thereafter the impression hammer 56 isagain moved downwardly to carry the audit strip 64 and the ink ribbon 15 intoncontact with the type carriers 58 to print a duplicate record upon said audit strip 64.
The upper end of the extension 12 of the arm 10 forms a convenient fingerpiece 8U by which the shaft 'll and the guide roller 65 may be rocked counterclockwise if. necessary to assist in properly inserting and locating record material within the machine.
While the forms of mechanisms herein shown and described are admirably adapted to fulll the objects primarily stated, it is to be under-` stood that it is not intended to conne the invention to the forms of embodiment herein disclosed, for it is susceptible of embodiment in various forms all coming within the scope of the claims which follow.
