TYPE-WRITING MACHINE Application filed. October 13, 1906.

Specification of Letters Patent.

Patented Nov. 17, 1908. Serial No. 838,859.

To all whom it may concern:

Be it known that I, IIERMA'N L. WAGNER, a citizen of the United $tates, residing in Mount Vernon, in the county of W'estchester and Stateof New York, have invented certain new and useful Improvements in Type- Machines, of which the following is a spool cation. y

This invention relates principally to that class of tabulating mechanisms for typewriting and other machines in which independently operable denomination keys are provided, although certain features thereof may be applied to other tabulating mechanlsms.

My invention is the natureof an improvement upon the construction shown in my pending application No. 323,588 (Patent N 0. 853,280), in whichthe denomination keys are shown mounted ina row on the ends of short arms which extend forwardly from the front bar of the paper carriage, denomination stops being rigidly connected to said arms and depressible independently one of another by the keys to engage column stops and placed side by side at letter space intervals, and each key arm with its stop forming a bail, the bails being of graduated sizes and nested together in two sets, and keybearing arms diverging or fanning out at each side of the set of stops to compensate for the greater length of the rows of keys.

One object of the invention is to improve and simplify the form and. nesting of the bails and to avoid faulty action thereof upon 'the depression of the keys. I place all of the keys directly upon the stop-arms, so that in each of the two sets of bails are comprised a large bail carrying a key upon its stop-arm and successively smaller bails within said larger bail and forming a regular nest, each stop-arm carrying a key. The keys are carried upon extensions which diverge to the right and left of thestop-arms, and means are added directly beneath the keys for arresting them to avoid distortion of the bails in action.

In the preferred form of the present invention one or more stops are introduced between the two sets of bails to further simplify theconstruction and economize room; said additional stop-arms being single arms and pivoted upon a common axis of the bails and carrying keys at their forward ends.

I is a plan of the front upper portion of an Underwood typewriting machine provided with my improvements in their preferred form. Fig. 2 is a sectional side elevation illustrating the operation of setting a denomination key and simultaneously releasing the carriage. Fig. 3 is a perspective view of two of the denomination-keys and stops. Fig. at is a diagram showing the same arrangement of denomination mechanism, as at Fig. 1', and showing the two middle stop-arms as lengthened and formed into-bails.

The usual cylindrical platen is illustrated at 1, and is mounted upon a shifting platen frame, (not shown), the latter mounted in the 11511211 manner upon a carriage comprising side bars 2 and front bar 4. The carriage is propelled by the usual spring barrel 5 and strap 6, and is provided with a letter spacing rack 7 to mesh with a pinion 8, the latter formin part of the usual escapement or letter feeding mechanism. Saidpair of arms 9 hinged at 10 upon the carriage frame and provided with a forwardly extending depressible arm 11, so that vby depressing the arm, the rack may be raised clear of the pinion 8, and the carriage may run along freely under the influence of the propelling spring The carriage has a front roll 13 running upon a track 14.

Extending along the carriage in front of the platen is a horizontal rock shaft 15 mounted in ears 16 projecting from a bracket 17, the latter (letachably securedby screws 18 upon the top of the front carriage bar 4. Said rock shaft extends through the end bar 2 of the carriage and is provided with a short arm 19, to vibrate a lever 20, and thereby depress the arm 11 of the rock frame 7, 9, and release the carriage. A carriage release bar 22 extending along the carriage in front of the keys is mounted byarms 23 and carriage may be released by the finger of the operator at the same time that a denomination key'is depressed.

Referring to Fig. 4:, it 'will be seen that rock shaft 15 between the collars 23 are t 0 sets of bailsfof graduated sizes, tliebai s being nested one within another, and thesets of bails being placed side by side, each'bail:

rack is usually provided at its'ends with a.

collars 23 upon the shaft 15, so that the mounted loosely upon the carr1age releasing 1-0.5

depressible independently of the others.

The largest bail in each set is numbered 24, the next 25, the next 26, and the remaining balls 27 and 28. Each bail comprises a pair of arms 32 and 33, both arms extending forwardly from the rock-shaft 15. The arms 32 are straight and parallel and mounted at letter space intervals and form a system of ten denomination-stops. The denomination keys 34 are mounted in front of the stops upon extensions 35 which diverge forwardly from the bail-arms, such divergence being necessary where the keys are mounted in a in one set correspondto those in the other a: small compass.

outer arms of the bails return the latter. to

but are oppositely disposed, that is to say, the shortarms in one'set of bails are upon the left while the corresponding arms in the other set of bails are on the right of thesystem of stop arms. The smallest bail 28, whose stop-arm carries a key at the extreme end of the row of keys is nested within the next larger bail 27 which carries the next key; and the bail 27 in turn is nested within 26 which carries the third key and is in turn nested within 25 carrying the fourth key; the bail 25 being nested within the largest bail 24v carrying the fifth key. By means of this construction and thisposition of the bails, ample-length of bearing in axial direction is secured even for the smaller bails, while the end system of bails is kept within Springs 36 under the normal positions. All except the two middle extensions 35 are branched out from the stop arms 32 between the ends of the latter as seen be'stat Fig. 2, so that the outer extensions when depressed may clear the adjoining stopswhich they-overlie as at Figs. 1

and 4; the'point-of branching being carried gradually backward from the middle to the sides of the system, to give clearance for the I extensions with relation to one another.

The bracket 17 is formed at its rear edge, with an upturned comb 37 toguide the bailarms and the front edge of the same plate or bracket is also bent up to form a corresponding guiding comb 38 .for the 'same' arms.

' In .0 eration, any desired denomination key 1s epressed, the finger at the same time pressmg down the release key 22. The carriage is then drawn along by the spring 5 until arrested by the engagement of the de-' pressed stop 32 with a column stop 40 provided upon the framework. tion key. and release key are then relieved -of The bails- The denominapressure and the type keys manipulated in the usual manner, types 41 striking-as usual mounted at the front of the machine where 7 they may be conveniently seen and operated, but also that they are below the line of vision. That is, the tabulating-mechan'ism does not come between the line of writing onthe platen and the eyes of the operator.

Referring now particularl to Fig. 1, it will be seen that in place of bails 24, single stop-arms 24 are employed having forwardly divergent extensions 35 the two outer bearing the twomiddle keys34. Said mid-' 1 die keys are but littleotfset from said arms 1 24 and hence the latter maybe sufliciently 'guidedand steadied by means of the guiding combs, so that it is .unnecessary to employ bails for these keys, whereby the tabulatin mechanism is somewhat more compacted an its'cost somewhat reduced.

Beneath the keys is an arresting bar- 43 supported bymeans of arms 44 extending forwardly from the bracket 17. This stop bar. will prevent undue depression of the keys and consequent distortion of an injury to' the extensions 35,. especially at. the extremities of the keyboard.

The bails 28 may in some cases be omitted and the denomin'ational lettering upon the keys changed accordingly. 1

Variations may be resorted. to within the scope of the invention, and portions of my improvements may be used without othersuv ids Having thus described my invention, I I
