Abstract: 2739. Cavagnino, M. Pionzio-. Feb. 10. Receipts, checking and recording.- In keyboard autographic register apparatus for securing the correct entry of commercial transactions such as cash receipts, with the object of afterwards copying such entries into a set of account-books, each key is either simple or combination and opens apertures over all the record-strips or the like where the transaction should be entered, means for feeding the register strips, for operating indicators, and for restoring the parts to normal position being also described, together with simple interlocking-means. Figs. 1 and 3 show the machine in plan, with the cover removed, and in section, respectively, the casing being divided into compartments for the recordstrips of the day-book 3, and of the dissected accounts for the ledger 4. In the first compartment, there is a double roll of paper upon the reel 5, both sheets of which pass over a writing- plate under the window 17, Fig. 4, and are simultaneously separated by a transverse copying-ribbon 18, provided with an external hand - feed. The sheets pass over tension rollers and are received upon the reels 6, 7, respectively, the three reels being hand-fed between each entry by one rotation of a handle 14 operating pawl, ratchet, and spur-gearing. There are twenty narrow record - strips in the second compartment, the feeding-reels of which are constituted by the ten divisions on each of the shafts 24, 26, and the receiving-reels by similar divisions on the shafts 25, 27, and each strip passes over a writing-plate normally covered by a shutter 42, which is opaque at its lower third, bears the title of the account on its middle third, and is transparent at its upper portion to allow inspection of the previous entry. Every possible transaction has its key 45, which either depresses a single lever 50, 51 directly, or a definite combination of levers through a pivoted coupling-frame 49 and suitable linkwork 52 ... 56, there being one lever allotted to each of the twenty shutters and adapted to withdraw it by means of the linkwork shown. By means of gearing, the single revolution of the main handle also feeds the narrow strips and simultaneously closes all the open shutters by rotation of a skeleton drum of bars 68, which strike against the levers 50, 51 to return them. In the modification shown in Fig. 9, there are twenty shutters as before, but each set of ten strips is replaced by one broad sheet 71, 72, the four reels thus required being mounted in pairs upon carriages which can be slid transversely into place upon rails 80, 82. The shutter operation is as follows :-Each key-stem has a cross-bar 115 with downward rods 116 resting on the particular levers 117 concerned in the transaction, there being twenty levers as before. Each lever when depressed lifts the hook 132, and the arm 133 falls into the position 133<1>, so that, upon the single key 140 being forced in, the cross-bar 148 may further depress such arms into the position 133<11>, the attached arm 134 simultaneously opening the proper shutter 119 or 120 by means of the linkwork shown. The return of the parts is effected by the closing-key 168, which causes an angular motion of the framework pivoted on the shaft 173, carrying restoring-bars 177, 178. The same parts give motion to a shaft 182, which has a rapid screw thread engaging with a stationary nut to produce longitudinal movement of -the shaft and force a conical india-rubber locking-plug into a recess in the main operating-shaft, the parts being locked while any shutters are open...Indicators 124, 125 display the names of any accounts with open shutters. In a second modification, the entries are made in the columns of an account-book, along the upper edge of which are shutters normally covering the titles of such columns, adapted to be displaced singly or in combination by the keys, and to be all lifted about a hinge for the purpose of turning the leaves. Fig. 13 shows the bookrest employed therewith to keep the opposite leaves horizontal, the covers of the book being supported on backing-pieces 207 provided with a frame 208 and adjusted as to height by the two equal parallelogram four-bar motions indicated. Opposite motion of the upper bars 220, 222 is secured by a handle on the shaft 209 and the train of spurwheels shown by dotted lines.
