TYPE-WRITING MACHINE.

Be it known that I, ALFRED G. F. KU-

' nowsiri, a subject of the Emperor of Germany, l)ut having taken out United States naturalization papers,.r esiding in Brooklyn borough, in the county of Kings, city and State of New York, have invented certain :new' and useful Improvements in Type- Writing l/Iachines, of which the following is a, specification.

, 'Ihisinvent'ion relates to typewriting machines, and more particularly to means for facilitating the insertion of the sheets into the machine.

A typewriting .machine is usually provided with a scale which cooperates with a pointer-or indicator for indicatingthe letter- [space positions of the typewriter carriage.

This scale is also usually provided with indications which may be used for determin- 7 ing the position at which the printing should start, when it isdesired to have the printing vcentrallylocated on a sheet, as for instance,

7 Q when writing headings, etc,

" machines To obtain the best results with this scale, have been provided with guides for the side edges of the sheet, which may V be adjusted so that each sheet is guided into the machine with the ,center thereof at the printing point of the machine when the indi- Qcator 1s ,atth'e center of the scale. One of these gu des ispro'vided for each side of the 7 :Work sheet. 1 usually been mounted so as to be indep Q the mach-me;

which arecommonly used such as, ten inch, 7

particular work sheet of a certain unknown width, the sheet is placed on the paper table and the lateral paper gages-are simultaneously adjusted until they are located at the side edgesof the'sheet. The dial connected therewith then indicates the width of the paper. For example, if the sheet is eight inches in width, the dial wheel will read eight inches. The pointeron the usual carriage margin gage is theninoved past' the eight inch indication on a scale provided adjacent the usual letter-space scale, an amount which is equal to the width of the margin desired on'the sheet.

Taken alone, the gage mechanism is advantageous in that with the one movement the two gages may be properly ad usted to various predetermined positions.

I combine with the connectedgages a centering scale which is always in proper relation to the printing field on the platen, and

hence is always usable for sheets of any width, since the sheets are. always guided to their true'central positions in the machine.

The means for bringing about the above results may comprise ashaft having a pair of oppositely directed spiral grooves which commence at the opposite extremities of the shaft, and extend to the center of the ma-' chine. The lateral guides may be mounted which slide along the said Each collar my beprovided with a spline which extends into the groove. The shaft is provided with a finger piece by means of which it may be rotated in either shaft.

To indicate'the positions of the lateral guides, the shaft may be provided with a' worm gear which rotates a gear bearing indications which are visible through a sight opening.

The platen frame is mounted in a step-by-st'ep moving carriage having a transverse bar 16 arranged at the front thereof.

To indicate the letter-space positions of p the platen, a pointer 17 is securedto the transverse bar 16 on the carriage, This pointer 17 cooperates with a scale 18 on a scale bar 19 secured to the machine frame 20.

The scale 18 isprovided with an indication for each letter-space movement of the typewriter carriage, and is numberedat each tenth letter-space.

in the center of the'shee't, a centeringscale 21 is provided and arranged adjacent the letter-space-scale 18. To center a particular word, upon the [work sheet. the operator moves the carriage by means of a finger plcce 22 until the pointer 17 thereon is located opposite the extreme right-hand indication qriage-feeding space bar is then struck once for-each letter in the word. The operator 5O thennotes the indication on the centering scale opposite the pointer on the carriage,

andthen moves the carriage until 1 the pointer'l? is'locat'ed opposite an indication on the usual letter-space scale which corresponds to the indication noted on the centering scale 21. F Or instance,if a word is to be centered, the carriage will be moved to the extreme right-hand indication on the centering scale, which, in this case, is marked #50,? and if theword comprises t'en letters,

' the space bar will be operated ten times, thus I feeding the typewriter carriage ten spaces,

upon-the centering scale 21. The usual careesr summers cos scale 21 is equal to two indications on the letter-space scale 18.

The typewriter carriage is then moved to bring the pointer 17. thereon opposite the indication 45 on the letter-space scale 18, and the typewriting 0f the word should commence from that points From the foregoing, it will be seen that to a get the proper results from this scale, the work sheet should be centrally located upon the platen with respect to the scales. To properly guide thesheets into the machine, for this and other purposes, the present invention provides paper guldes, which in many respect are similar to those on the usual Underwood machine.

According to the present invention a pair of lateral guides 23' and 24 are arranged 'so as to be'adjustably mounted along the paper table 15; and each of these guides'are provided with a body portion 25 which is bent at '26, so as to extend over a rolled rim 27 of the paper table. To the rear of the rolled rim 27, each lateral guide is pivotally mounted by means of cars 28 to arms 29 on collars 30. Thecollar 30 of each lateral guide is mounted on'a shaft or rod 31 carried by brackets 32 secured to the paper table by screws 33. The rod 31 is held against lateral v movementfin the brackets by collars 31 secured to the rod 31.

Inorder to hold the collar 30 and arms 29 on each lateral guide against rotary movement, each of the arm 29 is provided with,

ear v3 1 through which extends a rod 35 V y fixed to the brackets 32. The lateral guides In order to indlcateto the operator at what letter-space the carriage should be po-- sitioned', when it is desired to write a word 23. and 24: are mounted so as to always beat equal distances from the center of the machine, and means are provided so thatthis equal distance is maintained during adjustment of the guides. Thus. it willbe seen, that if a great variety of different sized sheets are used in the machine,it is a com tageous results, the rod 31, upon which the guides 23, 24 are mounted, is provided with a pair of oppositely disposed spiral grooves 36. These grooves 36 are cut in the rod 31, so as to extend fromboth outer ends of the rod to the center of the machine. Each ofthe collars 30 of the lateral guides is 'rowdedwith spiral roove 36.

When the handle 38 30 of each lateral guide being held center of the machine a feather or spline 37 whiehextends into the grooved rod 31 is rotated'by a againstrotary movement by the rod. 35; and

"by' reason ofits splined connection with the rod 31, is moved "the groove and along th rod by 'foll'owin thus moves the lateral guides verse When tn.

e's'sr avaitaete the handle 38 and rod 31 are rotated.

An indicator 39, pivotally mounted upon a bracket 40 secured to a cover plate 41 of the typewriter carriage, comprises a gear portion 42 which meshes with a worm gear 43 secured to the right-hand extremity of the grooved rod 31. hen it is desired to adjust the gages, for example, for inserting ten inch paper, the operator rotates the handle 38 until the numeral 10 on the indicator appears through a sight opening 44 in the bracket 40. As the handle is rotated the lateral guides are moved and the worm gear is revolved, thus rotating the indicator.

In order that the operator may determine exactly when the lateral guides are in proper position, each guide is provided with a detent ball 45 mounted in a housing 46 and normally pressed against the outer surface of the grooved rod 31 by a spring 60 within said housing. The grooved rod 31 is provided upon its surface between the grooves at various positions with detent notches 47. The ball 45 on the lateral guide enters this detent notch when the lateral guide is in exact position for the guiding of a sheet, the width of which is shown by the indicator 39. In addition to this the ball 45 yieldingly holds the lateral guides in this posi- The indicator 39 for the lateral guide is not only advantageous in connection with the centering scale, but also for the purpose of aiding the operator in locating the proper position for the lateral guides. For instance, instead of having to place the sheet in the machine and move the lateral guides up against the side edges of the work sheet, the operator with the present device knowing the width of the paper, simply adiusts the lateral guides by rotating the handle 38 until the proper indication appears in the sight opening 44.

It will be unders ood that this indicator 39 need notnecessarily indicate the width of the sheets but may be provided with indications designating the various forms used.

The usual carriage margin gages each comprise a block 47 slidable upon rods 48 and 49 mounted in the machine frame and held in position on said rod by a. suitable locking means. This locking means may be released when it is desired to adjust the gages by means of a finger piece 50. The margin gage at the right-hand side of the machine is adapted to cooperate with a tap pet 51 mounted on the transverse bar 16 of the typewriter carriage, and the gage at the left-hand side of the machine is adapted to operate with a lug 52 also on the transbar 16 of the typewriter carriage.

"e carriage is returned. the lug 52 st a lug 53 carried by said marwit es gin gage 47 and thus stops the movement of the carriage. In order that the carriage may be moved past said lug 53 on the margin age 47 at the right-hand side of the machine, the lug on thecarriageismounted upon a lever which is pivoted at 54 and which provided with a finger piece 55. Both these right and left-hand gages are adjustable to limit the movement of the typewriter carriage in both directions, and are usually set so as to provide a margin on the work sheet.

In addition to the foregoing uses and ad- 'ant-agcs, the present in vcnti on may be used in connection with the carriage margin gages. For instance, if a work sheet of unknown width is. placed in the machine, the lateral guides 23 and 24 are adjusted by the handle 38 until they engage with the side edges of the work sheet. The reading on the dial of the indicator 39 is then noted and this notation is taken in connection with a scale 56 which I provide adjacent the usual letter-space scale 18. This scale is stepped off commencing from the center of the machine in both directions and extending to the outside of the machine to indicate inches and fractions thereof. For example the indicator discloses the numeral 10, which may signify ten inches, and let it be assumed that a margin of one inch is required at each side of the paper leaving eight inches for writing space. The pointers 59 on the carriage gages are then moved to the numeral 8 on the scale 56. The lateral guides may be held against the paper table by means of a spring 57 connected to the arm 29 and bearing against the rear portion of the lateral guides. This flexible connection of the lateral guides with their support aids in attaching the device to the machine.

The center of the grooved rod 31 may be supported by means of a bracket 58 secured to the rear of the typewriter carriage.

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