Original application med May 20, 1916, Serial No. 98,853. Divided and this application nlecl March 27, 1918. Serial No.224,959.

To all whom it may concern:

Be it known that I, O'r'ro THIEME, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Type-Guards, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertans to make and use the same, reference being had to the accompanying` drawings, forming part ofdthis specification, in which- Figure 1 is a side elevational view through therear end of a calculatingr machine showing my improved type guard in position thereon.

Fig. 2 is a vertical sectional view through the same.

Fig. 3 is a horizontal sectional view through the same.

Fig. 4 is a side elevational view of the printing segments detached.

Fig. 5 is a detail view partly in section ofthe inking ribbon guide for the printing segments.

Fig. 6 is a front elevational view of the ty e segments. This invention relates to a new and useful improvement in type guards for printing type of calculating machines, and is a division of an application led by me May 2.0, 1916, Serial Number 98,853.

yIn the parent case there is illustrated and described a tally roll attachment for the Moon-Hopkins billing` machine including in its structure denominational racks 100 which u cooperate with register wheels 119 and 268. Type segments 561 mesh with the rear ends of these racks for the purpose of making a printing1 impression upon the tally roll` strip 600 carried by the laterally adjustable frame 503 which, when vibrated, causes its platen to press the paper against the inkingY ribbon in the printing line and eiiect a printing impression from the tally roll segments. The. record thus made may be of the items or of the totals indicated the register wheels H9 or 268.

Means are also shown in the parent case for laterally adjusting the irame 503 wherehy the records made on the tally strip may be arrangedin coiunn:l order.

Means are also disclosed n the 5% enecting the feed of the tally roll strip, returning the frame 503 to its normal or starting position, and controlling the several operations of the frame 503 automatically by adjustable stops on the main paper carriage identified with the words-printing mechanism of the typewriting mechanism, not herein shown. These form no part of my present invention, as this application is coniined'to the construction and method of operation of the type guards which coperate with the tally roll printing segments.

As the platen 505 carried by the vibrating frame 503 extends entirely across the printing line in any lateral position of the frame 503, and as the zero printi type on the segments 561 are normally in t e printing line, it follows that some means must be provided to prevent the printing of zero `type to the left of any number recorded, and

Whenever the denominational racks 100 are moved forward, they position the segments 561 so as to present appropriate printing type in the printing line, and if after said type are so positioned, the frame 503 is vibrated so as 'to cause the tally roll strip 600 to be pressed against the inking ribbon arranged 'bove the type, a printing impression will be made, all as described in said parent ense.

Each of the type 'segments 561 carries printing type 562 on its periphery, and each of said printing segments in addition is provided with a shoulder 563 on its hub. 564 indicates a rocking "iP-shaped lever, there being one ci such levers for each printing segment. eac i lever 'being independently held rearwardly against a stop ha? 5G @a hy means of a spring 565. 'The rearward extension or shoulder ci this T-sharmd lever 5de is thus cm=ed to bear against the shoulder 563 on 'the hui ot the printing segments.

per

the type 562, the rear or free end of said guard being bent upwardly so as to Provide a space overthe zero type for the inking ribbon 60021. Whenever the racks 100 move forwardly, they will cause the printing segments 561 to be rocked rearwardly, and consequently the zero of each operated segment will be moved rearwardly below the inking ribbon so as to successively bring printing characters 1, 2, 3, 4, etc., opposite the printing line. Upon the initial rearward movement of the segments 561, the shoulder 563 will rock the "shaped lever 564 forwardly, thus carrying with it the guard plate 566 which will uncover the type in the printing line in readiness to receivethe impression stroke of the platen. Each one of the T- shaped levers 564 is provided with a bent portion 567 see Fig. 6) which extends behind the neXt adjacent T-lever of lower order so that when' a segment 561 of any higher order is operated, notwithstanding the fact that the racks 100 of lower order are not operated, the T-shaped levers identified with the printing segments in the lower orders will be rocked forwardly by means of these projections 567 so that the zero type in the printing iine in such lower orders will be exposed to maire a printing impression. The guards over the Zero type in the higher orders above the highest digit in the number being recorded, will not be moved, and consequently, will bind the zero type in such higher orders. When the type have been brought to the printing line and a printing impression is made, the restoration of the racks will cause the printing seg-i ments to be returned to their normal or home position in which the zero type are in the printing line. In order to avoid excess movement of the T-shaped levers 564, the hubs'oi" the printing segments below the shoulders 563 preferably formed concentric so that after the 197 type has been positioned to the printing line, the successive movement the segments in bringing the 2 3 and 4 typeto the printing line, will cause the rear end of the T-shaped lever to ride on the concentric portion of the hub, and thus the type guard in exposing the type the printing linel will not be given an excess unnecessary forward movement. @i course when the segment is restored and 'the "nub- 563 passes beneath the rearward extension of the clm-shaped lever, said 'lshaped lever will move rearwardly until arrested by the bar 564g, in which position the type guard will cov the zero type.

As shown 5 and 6, there is a ribbon guide 616, there being one of said ribbon -guides arranged at each side of the printing type so as to guide the ribbon over the printing line, z'. e., the line in which the zero type are normally in printing position. These ribbon guides are mounted on ends of naeaevi plates having slot and pin connection with arms 617 and are normally held outwardly by means of springs 618 so that when the platen makes a printing impression, these guides will yield slightly and then lift the inking ribbon away from the printing type so as to permit their free restoration and at the same time enable the inking ribbon to remain in its printing line position. I have not herein disclosed any means :for

'feeding the inking ribbon, as the same is sot forth in the parent case before mentioned.

What I claim is:

1. In an apparatus of the character described, the combination of denominational type segments whose zero type are normally in the printing line, a type guard normally covering said zero type, and means for moving said type guard upon the actuation of its companion segment whereby the type positioned in the printing line will be uncovered.

2. In an apparatus of the character described, the combination of denominational printing segments whose zero type are normally in the printin line, exible type guards which norma ly cover said zero printing type, and means operated by said `type segments whereby said type guards are moved to uncover the type in the printing line of the actuated segment.

3. In an apparatus of the character described, the combination of denominational printing segments whose zero type are normally in the printing line, iiexible type guards which normally cover said zero printing type, means operated by said type segments whereby said type guards are moved to uncover the type in the printing of the actuated segment, and connections between the said type guards whereby the zero type to the right of any actuated segment will be exposed.

4. In an apparatus of the character de' scribed, the combination of denominational printing segments whose zero type are normally in the printing line, exible type guards which normally cover said zero type, yielding ribbon guides for supporting au inking ribbon between said zero type and said type guards, means for retracting said type guards to uncover said ribbon and expose the type in the printing line, and a platen for ed'ecting a printing impression on a strip of paper over the exposed type only.

5. The combination with a rocking printing segment, of a type guard holder normally in engagement therewith so as to cover the type on the printing line, and means whereby when the digits on said segment are moved to printing osition in one direction., said type guard wi l be moved in the opposite direction to expose the type on the printing line..

6. The combination of a Erinting segment having a projection, a roe ing type guard support coperating with said projection and movable in an opposite direction to the movement of said printing segment when the latter is moved, and a type guard carried by said support, the free end of Which is normally located over the type in the printing line.

7. The combination of a printing segment having a. shouldered hub portion and a spring-pressed type guard support coperat-ing therewith, and a type guard carried by said support.

8. The combination o f independently operated denominational type segments, guard supports operated thereby, there being one of said supports for each of said segments, and Hexible type guards carried by said support, the free ends of which normally cover the type in the printing line, means whereby said type guard supports are actuated to uncover the type in the printing line whenever its companion type segment is operated, and means whereby said type uard supports may be operated independently of any movement of said type segments.

In testimony whereo` I hereunto aiix my signature this 21st day of March, 1918.

OTTO THIEME.
