pnrrnn s'rATns PATENT I HERMN L. WAGNER, or MOUNT VERNON, NEW YORK, ASSIGNOR To UNDER oon TYPEWRITER COMPANY,-

, or NEW-JERSEY;

To all whom/fit may concern: Be it known that I, HERMAN L. WAGNER, a citizen of the United States, residing in I Vernon, in the county of Westchester and State of New York, have invented ,cer-I tain new and usefulImprovements-in Type- Machines, of which the following is a specification.

v g This invention relatesto that class of tabulatingmechanisms for typewritingand other which independently operable denomination keys are provided.

The principal object of the invention is to provide a simple,- comdpact, inexpensive and ,5.

' ism which can readily tabulating mechane be attached to machines in course of manufacture or. alreadyin' existence. w y In the preferred formof the invention, the keys are mounted in a row. on the ends of short arms which, extend forwardly from the out bar of the paper carriage, and denomination stops are formed on or rigidly' connect-- edto said arms, soas to be depressible independently of one another-by the keys into,

conveniently operate position to engage column stops provided upon the framework, p

One of the aims of the invention is to secure compactness of the tabulating mechanism,

and to this end the denomination stops are placed side by side at letter space intervals,

bearing arms are mounted some.

I on one side and some on the other of the series after appear.

of stops, the latter being elo'se .to the keys.

The key-bearing arms taken withthe stopsform bails of graduated sizes which are nested together in two sets the key' -bearing' arms fanning out at each side of the set of stops, so as to afford room for the keys, the row of keys being much longer than the row of stops.

I" show my improvements applied to a power-driven carriage whichis provided with a'releasing mechanism, inclusiveof abai extending along the row of denomination keys in juxtaposition thereto, so that it is convenient' to depress said release bar simultaneously with the depression of any selected key. Other featuresand advantages will herein- In the accom anyin drawings, Fi ure 1 is aplan of the frdht upp er-portion ofagn Underwood typewriting machine provided Fig. 2 is .a front elevation of t e parts seen at Fig. 1, but with wardly and are united ing 26.

Y., ii-CORPORATION key. Fig. 4 is a perspective view of one of the denomination keys and stops and a portion of the releasing mechanism. Fig. 5 is a side elevation of one The usualfcylindrical platen is illustrated at 1, and is mounted upon a ame, (not shown,) the latt'er mounted in the usual manner upon a carriage comprising side bars 2,and front bar 4. a The carriage is propelled by the usual spring barrel 5 and strap 6, and is rovided with a letter spacing rack 7 to mesh witha pinion 8, the latter formin part of the usual escapement or letter fee ing mechanisms Said rack is usually i'ovided at its of the denomination keys andstops;

shifting platen T ends with a pair of arms 9 ed' at 10 uponthe carriage frame and provided with a forwardly extending "depressible arm 11, so that arm, the rack may be raised clear of. the pin by depressing the ion8, and the carriage may run along freely under the influence of the propelling springfi. The carriage has afront roll 13 running upon a track 14.

Extending along the carriage irifront oi' the platen is a horizontal rock shaft 1 5 mounted in'ears 16 projecting from a bracket 17, thevlatterdetachably secured by screws-1 8 upon the top of the front carriage bar dl Said rock shaft extends through the end bar 2 of the carriage. and is provided with a short arm 19, to vibrate alever 20, and thereby depress the arm 11 of the rack frame'7, 9, and release the carriage. Arms 21 are fixed by hubs 22 uponsaid rook shaft and extend forby a bar 23, so that bydepressing said bar, the carriage may be release Mounted loosely upon the carriage releastwo sets of bails of i being nested one within another, the sets of bails being-placed ing depressiible independently, of the others. The largest bail in the left hand set is numbered 24, the next in size 25, and the sptiailest are. correspondingly numbered 27, 28, 29.

arms extending forwardly from the rock at their forward ends v rock shaft 15 between the arms 21 aregraduated sizes, the hails.

side by side, each bail be- Each bail comprises .an arm 30 and a key-bearing arm 31 both shaft. The arms are straight and parallel and arranged at letter space intervals and form a series-of six denomination stops. This number of stops is increased to eight by means of single-arm levers 32 loosely pivoted upon the shaft 15 and extending forwardly within the sn'iallest bails 26, 29, and bearing keys 33 on their forward ends. The arms31 n in the left hand set of bails diverge or fan out at the left hand side of the system of stops and hear at their forward ends denomination sated by the divergence of the levers'or arms. .31.

All of the keys, levers and. stops are preferably confined between the arms 21 of the carriage releasing bail. tion stop hails are held up by springs 40 against a stop 41. The bracket 17 is formed at its rear edge .with an upturned comb 42 to guide the rear ends of both the diverging and The front edge of the same parallel arms. plate is also bent up to form acorresponding guiding comb 43 for the same arms. It will be seen that the denomination s'top mechanism is compactly mounted upon the single plate 17 which is readily attached to the front bar of the carriage. One of the advantages of the invention resides in locating the row of keys close to the row of stops, thereby securing great compactness, the keys being con nceted to the stops at the rear portions of the latter by the use of bails; this resulting in an easy action and proper movement of both keysand stops. y I

- n operation any desired denomination key isdepresscd, the finger at the same time pressing down the release bar 23 which is in juxtaposition to all the keys. The carriage is then drawn along by the spring 5 until arrested by the engagement of the depressed stop 30 with a column stop Mprovided upon. the framework. The key and bar are then relieved of pressure and the type keys manipulated in the usual manner, the types '46 striking as usual on the front of the platen. The release bar. may have finger pieces 45 upon its ends for convenience in releasing the carriage for other purposes than tabulating; and it wil'I be seen that owing to the proximity of said. keys 45 to the row of denomina.

tion keys, the bar 23 maybe dispensed with if desired, becausethe operator can conveniently depresscither of said release keys at the same time with any selected denomination key. One of said release keys may also be dispensed with if desired, thus leaving only a set of denomination keys and a single release key which is the same one used for The denominai general purposes, the denomination keys be ing located where they are convenient to said release key. The stops .44 are adjustable along a rack 47.1nounted upon the frame- -work, said stops being pivoted upon a fixed bar 48 parallel with said rack, all as set forth in my pending application No. 315,609.-

It will be seen that the keys are not only mounted at the front of the machine where they may be conveniently seen and operated, but also that they arebelow the line of vision. That is, the'tabulating mechanism does notcome between theline of writing on i the platen and the eyes of the operator.

' Variations may be ,resorted' to within the scope of the invention and portions of the improvements may be used without others.
