. Be it known Vthat I, EDGAR E. PHINNEY,

New York, in the county of New York and State of' New- York, have made a certain new anduseful .Invention in Calculating- -Machines; and I declare the, following to be afull, clear, and exact 'description of the same, suchas will enable'others skilled and u se the invention, reference being had .tothe accompanying drawings, and to letters or figures of reference marked thereon,- `which form a part of this specification.

Figure l is a -side view of the invention.

F ig. 2 is. a-detail side view .of one of the levers carrying theselecting-wheels, the op' ei'ating cam therefor, and adjacents parts.

lFig. 3 is a section on the 1ne;3-3, Fig` 2, The invention has relation to calculating machines of the type shownin the reissure patent to Baldwin, 13,841, dated December 8, 1914, and includingeertain of the modi- 1'917. ts object is mainly to provide for continuous rotation ofthe select' gears and to reduce the gear ratio, avoidin theA knock consequent upon the intermittent The invention consists in the novel construction and combinations of parts, as hereinafter set forth.. r

In the' accompanying drawings, illustrating the invention, the numeral 11 designates N the casing; 2 the transversely shiftable carriage wherein the registering wheels 13 and 440 89 are located; 3 4the operatingy handle; 4

the shaft carrying the selecting or primary wheels; 12V the intermediate gears;l 18 the depres'sble keys, a`nd 73vthe shaft of the and thedogsj. -I l Meansare provided to move the shaft 4 and theselectmg wheels thereon away from the intermediate gears after the selecting .wheels have been turned to setaip the numbers of fthe problem upon the intermediate gears, and prior to-the effective action of the carrying mechanism, this' arrangement allowing for` greater compactness' of design.

Said means consists preferably of levers 15', wherein the shaft 4; is journaled at lts ends,

In the rotatiomofithe cams, the carrying levers 15 will be rocked first to one' side of the normal position shownin full lines, Fig. 2, to move the shaft 4 and theselecting wheels toward the intermediate'gears(dotted llneflpiosition,` Fig, and, aft'e'r'the selects.:
