To all whom it may concern:

Be it known that I. ALFRED G. F. Konowa citizen ot the United States, residing in Brooklyn Borough, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Typewriting Machines, of 'which the following-is a specification.

This invention relates totypewriting machines, and moreparticularly to typewriting machines for typing bills :for telephone service. In the 7 operation of typing these bills, it required to type separately the amounts of United States taxes. It is desirable the sainetiine to keep track of the total amount of the tax items for .a day or other longperio'd. This has been done heretofore by providing -a standard typewriting machine withspecial 5 and 10 keys to be used tornoother purpose than the writing of tax items, and by providing registers tor separ-atelycounting the operations of the special keys orxtor separately adding the items written by them.

A 'lieature of-the present invention is the provision, in a machine having special 5 and 10" keys tor-thapurpose mentioned, of a singlereg-ister and means for operating the register to cause it to add together the items written hyboth ot the specialkeys. This register is, in general, of thetype of the well-known Veeder cyclometer, but has its units wheel especially arranged to enable it to count by five.

The invention isnot limited in scope,.however, to use in a machine provided with special keys for writingthe tax items, nor to keys for writing any particular amounts. but may be applied .to machine having only the usual complement of number-keys. It may also be used for other purposes than the rriting of telephone bills and for btaining the totals of items other than tax items.

The register is provided with an oscilla tory operating 1arin arranged to cause an operation of the register each time it .is oscillated, and connections are provided 1 between the and keys and the operating arm toefltect one oscillation of the operating arni when the 5 keyis operated, and two oscillations of the operating arm when the 10 key is operated.

It isan important point that the register ski,

is of the counter type, that is, of the type having a wheel of lowest denominationaan ranged-to be advanced at every operation of the register, and wheels of higher denomination arranged for operation only to carry overamounts run up on the wheel of-lowest denomination. A register of this type is -cheap to manufacture and easy to operate at a type stroke.

' Otherieatures and advantages will hereinafter appear.

In the accompanying drawings,

Figure .7 .is a side elevation rofone ofthe number-wheels of the register or counter other thanthe units wheel.

The typewriting -machine comprises the usual number and alphabet; keys 11, and, in -addition,--a special 5 key -5-.and'a special 10 key 10, preferably arranged at the rightehand end of the -keyboard,;a1l of.which keys .operatetypes 12 to printin-theusual manner. Abra-cket '13,-secured to the machine-frame 14, supports a register or counter-15 and connections between the reg ister and stems .1 6 and 17 depending from the special-5 and 10 keys. These .con-

nections comprlse a rock-shaft 18, borne l in abusliing 19 carried by thelbr-acket 13, and rearwardly-extending cr-ankearm 20 on the rock-shattlS. Headed studs Blatthe lower extremities .oiithe. stems 16 and 17 .depending i'ronrthe 5. and 10 keys overlie and engage the crank-arm .20 at distances from the 'centerof i the rock-shaft .18 which 2 1,57 reoe are so related to each other that a full depression of the 10 key rocks the shaft 18 through approximately twice the angle through which it is rocked by a full depression of the 5 key.

At. its outer end the rock-shaft 18 has a second crank-arm 22, which is connected to operate a gear-segment 23, pivoted. on the bracket 18, by means of a pin on the crank-arm 22 and a slot- 25 in the segn'ient. The gearsegment meshes with and rotates a pinion 26 having a flange 27 upon which are mounted a pivoted pawl and a spring 29 for pressing the pawl. A hort sha 30 mounted on the bracket 13 terms the be ing for the pinion 26 and also for a dish 3 having a single tooth The spring 29 presses the pawl 28 against the toothed disk 31 to effect a one-way driving :onnection therewith. A crank on the disk 31 is connected through a link at to oscillate a register-operating arm 35, the arrangement be ing such that each full revolution the disk causes an oscillation of the arm The parts are so proportioned and arranged that full depression of the 5 key oscillates the arm 35 once and full depression of the 10 key oscillates the arm 35 twice. A spring 36, connected to the tail of the operating arm 35 and to the bracket 13, maintains the oper ating arm normally at the advance limit o its movement. A spring 37, connected to the geal segment 23 and to the bracket 1-3, re

turns the gear-segment to its normal elevated position, and, through the pinion 26,

returns the pawl 28 independently of the toothed disk 31 and hence independentl of the register-operating arm As has been stated, the register 15 is of the type 01": the Veeder cyclon'ieter. but has its units wheel modified to adapt it to count by five. The register-operating arm is connected with and oscillates a yoke 38, upon which is pivotally mounted a series of pawls 39 spring-pressed toward numberwheels 40 and 11 for cooperation with ratchet-teeth e2 thereon and with intervening shallow and deep notches 43 and as in the usual way, to advance the units wheel 4-0 one number space at each full operating stroke of the yoke. Stops 4-", for preventing overthrow of the wheels 40 and 41 and for locking them, are swung into and out of engagement with the wheels by the yoke 38. Spring-pressed pawls l6 engage the wheels 10 and 41 and prevent retrograde movement thereof. The units wheel l-O bears alternately the numerals O and 5, and has five deep notches 44 arranged alternately with five shallow notches 43. By this arrangement a carry-over operation onto the tens wheel of the register is efi'ected at alternate operations of the register that is, each time that the units wheel is advanced from 5 to O. The wheels 41 of higher denomination than the units wheel 40 are arranged with nine shallow notches and one deep notch l ias usual, so that each tenth operation of one of them will be eti ective to cause a carryver operation onto the wheel of next higher denomination. It will be apparent that one full oscillation of the register-operating arm 35 will be cli'cctive to add tive to the total exhibited by the register, and that two full oscillations o i the registeroperatin arm will add live twice, increasing the total by ten.

The 5 key is shown .in its fullyalcpressed position in Figure 111 moving to this position, it moves the gear-segment 23 from the'position of Figure 1, through the position of Figure 2, to that of Figure 5. The segment 23 turns the pinion 26 through one complete revolution in this movement, and the crank through the pawl 28 and toothed disk 31, is turned in unison with the pinion, thus causing a complete oscillation of the register-operating arm to add iive to the total exhioited by the register. As the 5 key rises, the spring 37 raises the gear-segment 23, causing the pinion 26 to he otated in the reverse direction. The pawl 28 moves with the pinion 26 in this movement, but the toothed disk 31 remains stationary, thereby permitting the crank 33 and the register-operating arm to remain stationary also. The 10 key is arranged to rock the shaft 18 twice as far as the 5 key rocks it. and hence to depress the gearsegment 23 sutliiciently to cause two complete revolutions of the pinion and therefore tvo full oscillations of the register-oper ating arm 35, whereby ten w ll be added to the total exhibited by the register.
