5, certain new and usefulv Improvements in Typ e-Writing Machines, of which the following is a speciiication.

My invention relates to improvements in typewriting machines and more particularly refers to means for effecting a quicker and more accurate centralization of short lines, headings and the like. Usually this work is done by mentally deciding upon a central point onsthe carriage scale as a center, say number 35, then counting the number of letters and spaces in the line to be centered,

' halving the same, deducting the result from the and so obtaining on the scale the commencing point of the line.

The object of the present invention is to simplify this procedure,.obviate the necessity of calculation, provide a center' indicator, and thus minimize the risk of deviation from the center, relieve the mind of the operator of mental strain and facilitate the rodu-ction of work of the character speciedl To the above and other ends which will hereinafter appear,- my invention consists of the features of construction, arrangements o'f'parts and combinations Vof devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the different views, Figure 1 is a fragmentary vertical sectional view showing a portion of vthe carriage -of a typewriting machine with the device of my invention a plied thereto. Fig. 2 is a plan view of t e same.l Figs. 3, 4, 5 and are fragmentary detailed, sectional views of other forms of coniitruction. Fig. 7 is a fragmentary detailed front elevation of the. construction shown in Fig. 6. Fig. 8 is a diagrammatic developedview of the auiriliary scale shown Ain Figs. 6 and 7.

The devices of my invention are shownin the present instance applied to a No. 6 Remington machine, but it should be understood that theyare ap licable to various styles of typewriting macines. The invention is app icable to machines emplo the usual or any preferred form of carnage, whether the i? a rectangular laten frame 1 ofthe carriage with a platen s aft 2 journaledin bearings therein, a p laten 3 being mounted lon the Ejlpten shalt and provided with theusuel ger wheels 4 at the 4ends thereof. The forward cross bar of the platen frame has a bearing lug 5 secured thereto and which a roller 6 is ivoted. The rollerbears upon the shift rail 7 of the machine which is actuated in the usual 'manner to'change'the case position of the platen. The front cross bar of the platen frame has forwardlyv and downwardly extending'bracket-arms 8 to which a carriage'scale 9 is secured by screws 10. The carriage scale is vof the usual construction and extends substantially throu hout the length of the platen and is provide with the usual markings and numerical indices; the distance between adjacent marks corresponding to a letter space movement of the carriage. The shift rail 7 carries a pointer 11 which coperates with the carriage scale 9 in the usual manner. The construction thus far described is the same as that employed in the Remington machine.

The left-hand screw 10-which secures the carriage scale in place also connects a bracket arm 12 to the carriage. This bracket arm extends to the left and is projected downwardly at its outerY end as indicated at 13 where a screw 14 connects a bar 15 to the bracket. c A downwardly and forwardly projecting bracket' arm 16 is secured tothe carriage by the screw 10 at the opposite end of the carriage scale and a s'crew17 secures the right-hand end ofthebar 15 to this bracket. The construction. is suc-h that the bar 15 is arranged adjacent to and parallelwith the carriage scale, leaving an intervening space 18' between the two through which the pointer 11 may be seen. From an inspection oiFig. 1 it willbe seen that `the bar 15 extends slightly forward nofthe ointer 11 and at the left-hand end extends engthwise beyond the scale 9. An auxiliary scale or centering device 19, which is preferably made of sheet metal, is mounted to s lide along the bar '15. This scale may be mounted for adjustment in any one oie variety of ways.

In Figs. 1 and 2the member 19 is provided with fingers or cleats 20 which are bent around the edges ofthe bar 1 5 to connect it to said bar and aord a sli-ding movement of the auxiliary or centering scale on the bar 15. The front face of the member 19 is provided with a scale, the indices or markings 21` on which are spaced according to the corresponding indices 22 on the carriage scale 9; t at is to say, they are a letter-space distance apart. The numeral indices 23 on the member 19' extend progressively from right to left, whereas the numerical indices von the carriage scale extend progressively from left to right. In short the numerical indices on the one scale progress in an opposite direction from those on the other scale. It will be observed that the member 19 is substantially one-half the length of the carriage scale and yet the numerical indices range from O to "70 as on the carriage scale. If, for instance, the carriage scale 9 ,is seven inches long, the sliding scale 19 is preferably three and one-half inches long with numerical in* dices corresponding to those on the carriage scale. The divisions on the sliding scale therefore have double the value of those on the carriage scale 9 in thepresent instance, although this, as well as the length of the auxiliary scale, may be varied at will, as will hereinafter more clearly appear, but it is desirable to have the value of the divisions on the sliding scale a multiple of those on the carriage scale 9. From an inspection of Figs. 1 and 2 it will be understood that the pointer 11 not only'coperates with the carriage scale 9 in the usual manner but that it also coperates with the auxiliary carriage scale 19 for purposes which will hereinafter more clearly appear. A pointer 25 is or may be struck up from the sheet metal of which the sliding scale 19 is made and this pointer `ma extend from the zero point'or from the 1 point on the scale 19. Said pointer 25 extends towards and registers with the indices on the carriage 'scale 9. While I prefer to use the pointer 25, the zero index mark itself may be employed for this purpose and the ointer 25 eliminated.

T e device is particularly adapted for cen` tering short lines or headings on v'a page, so that the written matter is arranged as is shownby the following example In the use of my device shown in Figs..1 and 2, the sliding scale 19 is moved until its zero pointer. indicates on the scale 9 the space or position at which the operator wishes to center thework, which is at "40 in the' foregoing example, and the scale 19 is allowed to remain in its adjusted position so long as the point selected constitutes the required center. All that is then necessary is to ascertain the'number of spaces any par# ticular line will occupy and to commence writing at that number or degree on the auxiliary scale, as indicated by the pointer 11..

The sliding scale 19 being numbered to double the space value of the scale 9, the required line of Writing will m equally dis, tributed half to the left and half to the right of the indicated center. As an illustration, take the line in the foregoing example which reads simple in construction. The centering pointer 25 is set at the oint 40 on the carriage scale 9. It wil be observed that the line in question contains twenty# two letters and s aces. The operatorinove's the carriage untl the indeximark indicating the point 22. on the auxiliary scale 19 is in register with the pointer 11 and then proceeds to write the line simple in construc tion. The line will be evenly divided with eleven letters and spaces to either'side of the vselected center 40, the line beginning at 29 and ending at 50 on the scale 9. The rest of the work contained in the foregoing example is centered from the same point and is properly divided in a like manner on each side thereof. the beginning of each line is indicated on the auxiliary scale 19 and the end of the line is v19a is arranged below instead of above the carriage scale 9.

In Fig. 5 I have shown a construction in which the carriage scale 9El has a central longitudinally extending slot with corres onding indices on opposite sides of the s ot to form -a double scale. A central auxiliary scale 19k is connected to the main scale by shouldered screws 26 which slide in the central slot in the scale 9a and oppositely disposed pointers 25b are provided on the auxillary scale for coperation with both of the duplicate scales on the upper and lower edges of the main carriage scale member 9,

The operation of the different modified constructions thus far described is essentially the same as that described in connection with Figs. 1 and 2.

It is oftenvdesirable in writing headings to It will be observed that` a., b and c in Fig; 8 for use in single, double V g from' 0 to 35and be so proportioned l that the spaces between each pair of adjacent vindex marks give it a value which will aord a full letterspace between adjacent letters.

seated and secured at its ends.

aste rovide scales of diiierent values. fdiskqll e or circular pointer ``is-secured to provide double or triple spacing; that is to say, a full or double letter space between letters, thus eoorxnnrrive.

B o o .K x n E r i N e In order that it may be unnecessary for the operator to make any calculation to take into account the spaces between the letters in centering a line of this character, I have pro vided in the construction shown in Figs. 6, 7 and 8 a special multiplex auxiliary scale for this purpose. In this construction the screws 10 that secure the carriage scale to the arms 8 likewise connect bracket arms 27 to the carriage.

The l9werends of these arms form bearings in which a rod 28 is Surrounding this rod is a tubular member 19c which is provided with indices on diierent faces or sides thereof, the numerical indices on one face differing, from those on another face sci the tubular scale 19c so as to register with the indices-on the carriage scale 9, irrespective of the circular adjustment of the tubular scale on its rod 28. The three faces or scales of the member 19cv are represented at and triple spacing. Thus the scale a, for instance7 corresponds to the sin le spacing scales hereinbeforeV described, w ereas the scale b for double spacing may have indices BOOKKQEEPING 0n 'theiother hand, it may be desirable to leave two s -4 e written we shallA say, for example, conand the thir or triple space scale c may have a corresponding value, the scale being from ,017t0u2411l' ,l

In Writing the headings in' which a full let ter space is provided between adjacent ,let ters the multi lex scale `19 is turned to exose thescale to the operator. The line to sists of the wornsMt CENTERING SCALE.

'The words'and; spaces .of this line will be found to occupy twenty-eight letters space points of the carriage scale 9. The operator,

however, only counts the number of letters in the line which is fourteen and the spaces between words;` giving a single space value y to each double space. This will give a line which is Acalculated as fifteen. The centering or multiplex scale .is then adjusted along the rod 28 to attain the proper center in a manner hereinbefore described and the caraces between adjacent letters riage isset so as to bring the index mark, designating the point 15 on the Vscale o into register with the pointer 11 when the above and the. line will be properly centered from the selected point with an equal number of letters or spaces on either side thereof.

Various changes may be made in the details of construction and arrangement of parts without departing from my invention.
