CYLLCULATING-YHAGHINE.

To all whom it may concem: Be it known that I, EDGAR E. PHINNEY,

a citizen of the United States, resident of New York, in the county of New York and State of New York, have made a certainf new and useful Invention in Calculating Machines; and I declare the followin 'to be a full, clear, and exact description 0 .the same, such as will enable others skilled in the art to which it ap rtains to make and use the invention, re erence-being had to' shown in. the Reissue Patent No. 13,841,

dated December 8,1914, having for its object to simplify the method of procedure in Th the performance of the different arithmetical problems, in that the crank handle is always'started and stopped at the same place. A further object is to provide continuously turned operating gears, eliminating intermittently turning gears, with the consequent objectionable clicking noise as the gears are engaged. A further object is to reduce the gear ratio of the selectin or primary wheels to the driving gears an the registering wheels, thus reducing the power required to turn the crank handle and reducing the speed of the registering dials or wheels and rendering them less liable 'to be overthrown. A further object ,is to simplify the carrying mechanism, 'eliminatin the oscillating members thereof. All 0 these objects are enabled to be accom lished to advantage practically by the use 0 eccen trio gears in the driving connection, as hereinafter stated. I

The invention consists in the novel construction and combinations of parts, as here-, .inafter set forth.

In the accompanying drawings, illustrating the invention, Figure 1 1s a vertical section'on the line 1-1, Fig. 2; Fig; 2 is a horizontal section on the line 2-2, Fig. 1; Fig.

3 is a section on the line 3+3, Fig. 2;

Fig. 4 is a detail face view of one half or section of one of the primar or selecting wheels; Fig. 5 isa detail si e view, of the same;: F i 6 is a detail face View of "the other hal or section of one of the primary or selecting'wheels, and Fig. 7 is'a detail side view of the same.

tages stated, the crank handle is completely in one direction, or clockwise, for addition and multiplication, and completely in the opposite direction for subtraction and division, each time from the same starting point. Y

The primary wheels 5 have each a toothed portion extending around a portion of the,

periphery of the wheel,- and are mounted u on their shaft with the toothed portions 0 the wheels in substantial almement.

the keyboard and operate upon the registering dials as in the Reissue Patent 13,841,

referred to. l A

Carried by the shaft 73 are a plurality of collars, a, b, 0, d, e, f, g, h, and i, pro- .vided each with two radial thereto, with a carrying pawl or dog 7'. All of said arms m, m, fast ese primary wheels are controlled from "75 each radial arm being provided collars are fixed upon the shaft, and the carrying pawls are arranged in two oppositely pitched spiral lines, each series or set of pawls extending about one-fourth around the shaft, both together about onehalf around, and the two seris nearly intersecting or ending adjacent to each other. These carrying pawls are actuated by plungers seated in the-shaft of the intermediate gears 12, and operate the registeringegials through "said gears, as fully descri the Reissue Patent 13,841, hereinbefore mentioned.

The crank handle being turned as stated,

the shaft of the carrying mechanism will i be turnedcom letely therewith, by means of the train o spur gears 76,75, 74 and two members of a sub train of gearslO, 11,, 12, the gear 11 being located upon a short shaft 74 of and turning with the ear 74, and being the middle gear of said su train,

the gear 10' being fastupon the shaft of -the select-ing wheels and the gear 12 being fast upon the shaft of the carrying mechanism, whereby the shaft of the selecting wheels will be also turned constantl throughout the movement of the crank handle.

, The, gears '10, 11, and 12' eccentrically mounted upon their shafts, the selecting. wheels thereby turning at greater speed" during the second and third quarters of their revolution, or when in mesh with the intermediate gears, and at'less speed during the first and fourth quarters, when being moved into and away from operative position, or when the carrying mechanism is in operation, and the carrying mechanism turning at greater speed when in operation, or during the crank handle the selecting wheel is rotated at high speed, in mesh with the intermediate gear, and during the last quarter revolution the selecting wheel is returnedslowly to initial position. So, also, during the first quarter revolution of the crank handle, one series of carrying pawls will be moved rapidly past the intermediate gears, the plungers of which are not set for carrying; during the next half revolution of the crank handle, or while the selecting gears are in operative engagement with the intermediate gears to turn the same and set the plungers' thereof for carrying, the carrying shaft and pawl's will be moved slowly and the other series of carrying pawls will bebrought around into "operative position, and during the last quarter revolution, or while the carrying is being performed, the selecting wheels will be out .of engagement with the intermediate wheels, and said other series of carrying pawls will be moved rapidly,

v in operative engagement with the plungers of the intermediate gears.

And inasmuch as the operation of each series of carrying pawls ends short of the intersection of the two oppositely pitched spiral lines, a return arm or arms 14 for the plunger relating to each intermediate wheel is enabled to be fixedly mounted upon the carrying shaft, midway between the two series of carrying members, said arm being oppositely beveled at 14', to return all of the plungers of either series simultaneously to normal position'in either direction ofrotation of the carrying shaft. a

- The selecting wheels being rotated slowly while the carrying mechanism isbeing rotated rapidly, and vice versa, the strain upon the operating shaft or crank handle is'nendered even and balanced at all times during the turning thereof, facilitating accuracy and ease of operation. An eccentric gear being located upon the shaft of the carrying mechanism, as well as upon the shaft of the selecting wheels, the eccentricity and theconsequent variation in speed is enabled o be made less than there were an eccentric ear provided upon one of these shafts alone,

in train with an eccentric gear upon the shaft ofone of the larger" spur gears. WhatI'claim is: 7
