To all whom it way cow/0cm. i v F Beit known that l,HENRY M. FERRY, a

' adding machine and any ty e of typewriter.- .In the drawings, in Fig. 3, hoveshown &

'tion, reference. lining had therein to the ncsiding at l)et.roit, in the county of \IVn-yne and tate of Michigan, .hzrvc invented certain new and useful linprrwements in Machines for combining, in] Adding-hlnehine and Type- W riter, of which the following is n spcciiicccoinpmiying drawings.

lt is the-object of the invention to provide I means whereby it column of figures in a letter or invoice, prepared upon an ordinary type writer, may he nieclmnienlly added. in the present state of the art, adding machines are. usually novided with it printing mechanism. i) \\'lli(ll the different items, together with the sum total. are recorded upon :1 strip or |ll)l)()ll of paper. These machines are not, however, adapted for printing their record in the body ol' nletter or invoice, mid, as :1 consequence, there is" a chance that the items of the invoice "printed'on the ordinary typewriter may not correspond to, those which have been :iddedon the adding nmchine. By my improvement, on nddermachine and a typewriter, which are. ordinarily 3 independent 0 enlch other, may he quickly 1 thrown into cor'iperntivc association, assuring an exact correspondence in the record of 2 each, so for they have itemsin coin'n'ion.

D is a circuit closer, of any suitable construction,

which is operated upon the rocking of the shaf t B, andv which controls nn'elcctric circuit E, including a battery or other suitable generator F.

(l are the numerslprintin keys ofthe typewriter. H are sseries o rods respectively connected to the keys G, as hymeons of the clips I, and extendlng into operative relation to electroqnagnetsor' solenoids J.

Each of these magnets or solenoids is conuect-e d into one of the electric hircuits Econtrolled by the circuit closer Dof one of the hanks of keys, and. the arrangemerit is such I that the operation of'any oneofthelteysin a bank "will close the circuit, energizing the solenoid, and, through the, rods H, operating the key G of the corresponding numeral the, typewriter.

total. It will be understood that in mani ulating the ke s of the adder machine, t e numerals for t e different denominations of an item are successively operated from left to right, so that the typewriter will be 0 rated in the ordinary manner. The a der' machine is further provided with a cipher key 0 and a space-operating key P. which are connected by corresponding electric circuits with the similar keys of the typewriter.

What I claim as my invention is:

l. The combination with a typewriter and on adding machine, of electrical connections therehctwcen, a rock shaft in said' adding machine, a circuit closer secured to said shaft. and means on said shaft pro'ecting into the path of the key of the ad er for;

rocking said shaft to close the circuit u piin I the operation of said key.

2. The combination with a typewriter and an adding machine having a plurality of series of keys. each series comprising several keys of the same numeral, of a series of universal oars respectively actuated by all of the keys of the same numeral in the adding machine. a circuit closer operated by each universal liar, and an clcctro magnetic means controlled by said circuit closer for causing the i an adding machine, having a plurality of series of keys, each series comprising several keys of the same numeral, of electrically-operated means operated universally by all ol' the keys for the same numeral of the adding machine for automatically operating the corrcsponding numeral printing key of the typewriter.

5. The combination with a typewriter and i an adding machine, having a plurality of sosiiiiultiini-ous actuation of the key of the' typewriter for the corresponding nuiiiei'al.

11. The combination with a typewriter and an'addinp machine having ii plurality of series of keys, each series comprising several ries of keys, each series coin irising several keys of the same nnmcral, of e ecti'iral means for detachably coupling said machines to cause the automatic operation of the nu: ineral printing keys of the typewriter by all of the corresponding keys of the same numeral of tho addine machine.

In testimony whereof I allix my signature in presence of two witnesses.
