Abstract: 379,293. Typewriters &c. SANDERS, N., 92, Rue de Richelieu, Paris. May 21, 1931, No. 15075. Convention date, May 23, 1930. [Class 100 (iv).] Coupling machines for simultaneous operation ; driving - mechanism.-A punching - machine of the Hollerith type is actuated by the keys of a multibank calculating-typewriting machine of known type by switches in alignment with the key stems. The switches are housed in a recess in the frame of the machine and are fitted without modification of the existing mechanism. Contacts for each row of keys are connected to the corresponding selecting solenoid in the punching-machine and are fully closed after depression of the keys only when the key stems are jumped to hook to a locking plate. The " Returns " keys of the machine opens a main switch to disengage the mechanism. The Specification as open to inspection under Sect. 91 (3) (a) comprises an embodiment described in connection with Figs. 1 to 6 (Cancelled). Each key stem of calculating-machine, Fig. 1 (Cancelled), controls a switch 2, 3. These switches are connected by individual leads to contacts 7 on a board 6a which is attached to a board 6b with corresponding contacts wired to electromagnets controlling selector bars 14 of a punching machine. Six banks of keys K51 .. K59, a .. f, are wired to six rows of contacts a<1> .. f<1> on the board 6a. Contacts in rows dll, ell, f<11> on board 6b are wired to selector magnets q, p, n controlling punches representing 10, 100, 1000 francs. The row all is connected to row m of selectors for units of cash number and row c<11> to units of francs. Actuation of the keys of the calculating machine directly controls these selectors. In order that one key of the machine may control alternative selectors the contact 5 of row all controls a selector 5 c, t and selector 5 row m. Contacts 123 of row c<11> control selectors 100, 200, 300 of row l and selectors 1, 2, 3 of row r. Controls 1 .. 9 of row b<11> controls selectors 1 .. 9 of row s and selectors 1 .. 9 of row l. In order to effect the alternative control the contacts on board 6b are wired to a two-way switch g and are coupled to the appropriate lead when the switch is positioned by an electromagnet Jl. An electromagnet T operates a clutch 21 and an electromagnet R<111> is energized when a key R is depressed. The machine may be driven by a hand-crank or through a one-revolution clutch by an electromotor 22, Fig. 6 (Cancelled), which imparts continuous rotation to a drum 25. After an amount is set up on the keyboard a key 42 is depressed. This rotates a member 39 which turns a pin 35 to release a lever 33 and brake lever 31 controlling a friction strap engaging a wheel 26. This wheel 26 operates a shaft 10 Figs. 1 (Cancelled) and 6 (Cancelled), through a connecting rod 54b and is rotated one revolution and stopped by a roller 65 engaging the lever 33. The contact CC<1> is closed to actuate the punch selectors and the crank 55 lifts a lever 56 to engage a lever 60 with a finger which is depressed on the down stroke. To allow a tapper F73 controlling the carriage feed to rise a switch is controlled by a lever rocked by a non-adding plunger which co-operates with an abutment on the carriage when the latter is in the position corresponding to the registration of a cash number to close a contact BC. In operation, if a substraction of 38 francs 25 is to be recorded by cash desk 326. The contacts BC are closed and BS open ; contacts CR are open and the switch g is in the full line position. The numbers 3, 2, 6, are set upon the keyboard, and operation key 42 is depressed. The one revolution clutch rotates the shaft 01, the number 326 is printed by type P54 and contact C is closed. This energizes a circuit through relay J<1> which throws over the switch g and circuits through the digits 3, 2 and 6. The tabulating- machine is operated and the carriage is displaced. T h i s causes contacts BS to close and relay J is de-energized. The keys 3, 8, 2, 5 are then operated with a Return Key R. This energizes solenoids q3, r8, s2 and 5 Ct. The key R energizes solenoid R<111> and punches corresponding to the appropriate spaces on the card are selected. Depression of the key 42 then clutches an electromotor to a shaft which lifts the die plate to effect punching and feeds the card. This subject-matter does not appear in the Specification as accepted.
