CARRIAGE-SHIFTING MEANS FOR CALCULATING-MACHINES.

To all'wkom it may concern:

Be it known that we, JAY R. MONROE and EDGAR E. PHINNEY, citizens of the United States, residents of New York, in the county of New York and State of New York, have made a certain new and useful Invention in Carriage-Shifting Means for Calculating-Machines; and we declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

- particularly carriage wherein Figure 1 is a vertical section taken through a calculating machine having parts omitted, showing the device as applied, the section being taken on the line 1 1, Fig. 6. Fig. 2 is a detail sectional view on the line 2-2, Fig. 1, showing the depressible keys for op-, erating the shift rod, parts being shown in depressed positions in dotted lines, Fig. 3 is a detail side view of the fulcrum support, parts being broken away. Fig. 4 is a detail end view of the fulcrum support, the rod being shown as rocked to one side. Fig. 5 is a detail front view (partly diagrammatic) of the shift rod and the cranks thereof, showingin dotted lines the path of movement of the operative end of the rod, with the parts in successive positions assumed in dotted lines. Fig. 6 is a section on the line 6-6, Fig. 1. Fig. -7 is a detail transverse sectional view of the .carriage.

The invention has relation to calculating machines, having a pivoted carriage, and to ineproved means for raising the carriage upon its pivot and shifting it endw-ise.

Theinvention consists in the novel constructionand combinations of parts as hereinafter set forth. I

In the accompanying drawings illustrating the invention, the numeral 1, designates a casing or frame of the machine, and 2, the

registering or driven wheels or mechanism is located, said wheels having normal engagement 'with driver wheels mounted in the casing and actuated by suitable setting up mechanism and carrying mechanism.

The carriage 2 is pivoted and movable endwise upon a longitudinal shaft 3, of the Specification of Letters Patent. Patented Apr. 25, 1916,

casing, and is provided with means whereby it may be raised upon its pivot, and shifted endwise or longitudinally, the carriage being lowered upon its pivot to normal depressed position at the end of the shifting movements, said means being actuated by the depressible key device operable to throw the carriage in either direction according to which member of the key device is depressed, and consisting preferably of a rod or shaft 4, having at its rear end an outwardly turned or crank arm 5, engaging any one of a series of open-bottom notches 6 of the carriage, said rod having at its forward end two right and left hand cranked portions 7, 7 engaged respectively by lateral extensions 8, 8 of the depressible keys 9, 9, the rod having intermediately of its length a fulcrum support from the casing which will admit of it moving upwardly and downwardly and also turning or rocking upon its longitudinal axis as a center, said support including usually a sleeve 10, having horizontal pivot studs 10, engaging bearings 11, of the casing, the rod loosely engaging the sleeve and being capable of a rocking movement therein to one side or the other, a

spring 12, bearing at its lower end against the casing and at its upper end against the sleeve forwardly of the pivot studs. The carriage is provided with a forward stud 13, normally engaging any one of a series of open-top notches 14, of the casing.

In operation, if one shift key (the right hand key for instance) is depressed to move the forward part of the rod 4 downwardly against the tension of the spring 12, the left hand crank 7 will move downwardly with the right hand crank 7 and the spring 12, being located directly beneath the rod 4, and at one side of the point of pressure of the key at the outer end of the crank 7 will tend to move the forward part of the rod 4 upwardly a sufficient distance to rock the rod to the right, the rocking being however prevented until the stud 13, and the carriage, have been raised sufiiciently to allow escape of the stud from the casing notch, the rod 4 then rocking, by engagement of the key with the crank 7, in cooperation with pressure 1 Upon release of the shift key, the spring 12 will act to further raise or return the forward cranked end of the rod 4 to normal position, and preferably suitable springpressed means will act simultaneously therewith to insure such return, said means consisting usually of oppositely extending normally horizontal lugs 14, of the rod 4, having upper shoulders 15, against which the free end of a finger 16, pivoted at 17 to the sleeve, bears, said finger being held against said shoulders by a spring 18, carried by a rod 19, of the sleeve, said rod extending through the rear part of the finger, whereby as the rod 4 is turned or rocked as stated, the lugs will also rock therewith, the finger being raised by the left hand lug, and the spring put under tension to-insure the return upon release of the key.

The rear cranked end of the rod 4 is nor mally. upright, and will be thrown to the right or left as the case may be, about fortyfive degrees more or less, being a sufficient distance to shift the carriage endwise. In the rocking or return of the rod 4 to normal position, the end ofzthe rod is also falling, and consequently the path of return of said end is lower than its path of carriage operative movement; not sufficiently low however to avoid raising the carriage to some extent, the casing notches being deep enough to hold the carriage against endwise or return movement with the rod, and

the free end of the arm 5, slipping from the comparatively shallow carriage notch with which it is engaged, to the next notch of the carriage, ready for a repetition of the operation.

What we claim is 1. In a calculating machine, a casing, an \ndwise shiftable pivoted carriage, and means including a rocking reciprocatory rod or shaft having engagement with the carriage to raise the same upon its pivot and shift it endwise.

2. In a calculating machine, a casing, an endwise shiftable pivoted carriage, and means including a rocking reciprocatory rod and two depressible key actuating devices having engagement with the carriage to raise the same upon its pivot and shift it endwise in either direction.

3. In a calculating machine. a casing, an

endwise shiftable pivoted carriage, and

means including a rocking reciprocatory rod having a fulcrum support and crank ends having engagement with the carriage to raise the same upon its pivot and shift it endwise. v

1 4. In a calculating machine, a casing, an endwise shiftable pivoted carriage, and means including a rocking reciprocatory rod having a fulcrum support, an outwardly turned or crank end in rear and forward cranks, and two depressible keys engaging the forward cranks to raise the carriage upon its pivot and shift it endwise in either direction.

In a calculating machine, a casing, an endwise shiftable pivoted carriage, reciprocatory means having engagement with the carriage to raise the same upon its pivot and shift it endwise, and means for returning the reciprocatory means to normal position.

6. In a calculating machine, a casing, an endwise shiftable pivoted carriage, reciprocatory means having engagement with the carriage to raise the same upon its pivot and shift it endwise, and spring means for returning the reciprocatory means to normal position. r

7. In a calculating machine, a casing, an endwise shiftable pivoted carriage, means including a rocking reciprocatory rod having a fulcrum support engaging the carriage to raise the same upon its pivot and shift it endwise, and means for returning the rod to normal position including a spring engaging a member of the fulcrum support and a spring pressed device engaging said rod.

8. In a calculating machine, a casing, an

endwise shiftable pivoted carriage, means engaging the carriage to raise the same upon its pivot and shift it endwise in either direction including a rocking reciprocatory rod having a fulcrum support, a rear out wardly turned or crank end, and depressible keys engaging the forward end of said rod. and means for returning the rod to normal position, including a spring engaging a member of the fulcrum support, and a spging pressed finger engaging lugs of said ro In testimony whereof we aflix our signatures, in presence of two witnesses.
