WILLIAM G.- FARNUM, or ARLINGTON, VERMONT, issmmme -WYCKOFF, SEAMANS & BENEDICT, or ILION. NEW YORK-,A'CQRL i PORATION OF NEW YORK.

Be it known that I, WILLIAM C: FARNUM, a citizen of the United States, and a resident of'Arlington, in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Type-Writing Machines, of which thefollowing is a specification.

More particularly my invention relates. to printing point and line indicators for typewriti "machines, and'has for its object to provi e improved means of the character specified.

Tothis end the invention consists in certain features of construction, arrangements of parts, and combinations of devices, as hereinafter set forth, and pointeclout in the appended claims.

v In the accompanying drawings, Figure 1 is typewriting machine raised to expose the printin -point with part of the rear bearingrod an showing my invention in operating 'riage intermediate the Fig.2 and that shown in ig. 4, in which lat-. 3,

5o port it upon rail 3.

'- 1 position. Fig. 2 isa sectionalview on the line ac m of Fig. 1, but showing the carriage as shifted to print upper-case characters. Fig. 3 is a view similar to Fig.2, but with the carosition shown in ter view the carria e is shown as lowered and ready to print. ig. 5 is a fragmentary view of the upper part of the indicator. Fig. 6 is a vertical .front-to-rear sectional view of a type-writing machine embodying my invention.

In the several views, in which like parts are designated by like numerals of reference throughout, portions of the machine are omitted or broken away in order to disclose the invention more clearly.

*I have shown my invention applied to a No. GRemington machine, the keylevers a, links I), and type-bars 0 being of the usual construction and each type-bar carrying an upper-case type d and a lower-case typee,

Coming now more particularly to 'the -g mechanism proper of my inve1'1tion,: 25 r isyan I indicator orpointer pivoted orhinged at 26 to r:

a bracket 27, screwed or otherwise attached to any convenient fixed part of the upper'f portion of the machine, at the rear thereof and at or near the center. I have shown the in-:.;' dicator as having thetwo side pieces 28 28:

bent near their upper ends and-joined: at the top by the cross-piece 29, andthis is the form I prefer as best.combining'lightness and stability; but it will be understood 131131911 do not limit myself to the constructionshown':

Attached to the rear carriagerod-Sat or near its ends are two brackets 30, only%thefi left-hand one of which is shown',-"and sup ported thereby is the light-rod 31 Whichrun's 5 i substantially the length"of 1-the"-platerr.-j

Loosely embracing the ;rod 31 "at 32 is the-- connecting link or piece 33, which is hin ed or pivoted to the-pointer251M 34. The'dhu- 5: ble-acting spring 35, which, "with the 'link-33 controls the pointeror indic'atorf-25 which ,is =l 1ere shown in'the-fornr of 'wire, is pivoted at 36 tothe; supporting bracket 27 and at 37 to the indicator or pointer on a slight ollset thereof, the pivot 257 being slightly to the rear of the pivot or hinge 26, which connects the indicator or pointer 25 to the bracket 27. The cross-- piece 29 carries the indicating devices proper, which consist ol line and letter indicators for both upper and lower case, aswell as an indicater for the platen-scale 18.

Referring to Figs. 1 and 5, the lower-caseletter indicator is denoted by 38 and the corresponding lineiiidicator by 39. 40 denotes the upper-case-letter indicator, and. 41 the line-indicator. 42 denotes the platen-scale indicator, which serves for both positions otthe platen. 'llLe dlil'erence of position 'of the pointer 25 as to the line of writing is represented by the distance between the line-indicators 39 and 4-1 on the pointer 25 and is due to the change of relation between the fixed pivot 26 and the rod 31, controlling the pointer 25 when the pl:ttOIlflJLll'lUl by which. the rod 3] is carried is shifted to change case.

The operation of my invention will now be described. Referring to Fig. 4, the platen is seen in printing position. with the pointer 25 inoperative and ing contiguous to the ribbo=n-plate 22. The pointer 25 is held in this position by gravity, as well as by the action of spring35 pressing at pivot 37, which in this position of the pointcr25 is above an imagi nary line connecting pointer-hinge 26 with pivot 36. It will of course be understood that whatever be the position of the platen, longitudinally considered, in respect of the/ printing-point the pointer or indicator 2:") willalways be under control through its link 33, embracing the rod 3], carried by the platen-carriage. Suppose now that at any point of its travel in the printing direction the platen-carrier be swung about the hinges at 10 by the lift-piece'23 for the purpose of exposing the printing-point until it reaches that point in its upward travel-shown in Fig. 3. The pointer 25 has been moved to the )osi'tion shown in Fig. 3 by the connectinglink 33 and rod 31. The spring 35 has up to this point tended to assist gravity in keeping the pointer 25 as far from the platen 6 as 'the link 33 and rod 81 will permit. Just here, however, as pivot37 alines with pivots 26 and 36 the )ressure of spring 35 is nullified, being exerte simply to press the pointer 25 against its pivot 26 away from pivot 37. A slight additional movement of the platen-carrier in the upward,direction by means of lingerpiece 23 will bring pivot 37 below the imaginary line connecting pivots 26 and 36, and thereupon the action of the spring 35 will be reversed and the pointer 25 will be forced thereby into close proximity to the platen, as shown by the dotted lines in Fig. 3. \Vhen the end of the upward swing of the platen is reached, the pointer 25 is in the position pointer 25 away from the platen.

anisin. has a double action, tending at one stage of.

, other stage toward the platen.

shown in Fig. 2, the slight additional are of movement of the rod 31 in the platen-twine permitting thespring 3!) to force pointer 25 into substantial contact with. t along the line of the cross-piece 2-9. The iii- .dicator proper will now be in the relation to the printing point and line as depicted in Fig. 5, the upper-case-letter indicator 40 (here shown. as graved or cut into the crosspiece 29) indicating the printing-point, and the upper-case lineindicator 41,. which in its present town is a line giaved or cut into the metal of cross,- iiece 2), indicating the printing-line, and the pointer 42 indicating the corresponding )rinting-point on the letterscale 18. Had

its sliil t-rail 14 been s ii'fted to its forwardv or lower-case position before being turned up to ie platen the platen-earner through expose the line ol writing, the indicator would appear in relation thereto as shown in Fig. l, the lower-case-letter indicator (in' its present form shown as a notch 38 in the cross- )iece 29) indicating the printing-point, and the lower-case line indicator (here shown as the upper edge 39 of crossiece 25)) indicating the printing-line, 42 ill( ieating the printingpoint on the platen-scale, as before.

In returning the platen-cari'ier with its platen 6 to printing position the reverse oi the operation above set forth will take place, the double-acting spring 35 holding the pointer 25 in close proximity to the. plateir or a short distance of the are of return lilOVO- ment and until pivot 37crosses lilQlll below to above the imaginary line connecting pivots 26 and 36, whereupon spring 35 acts tol orce thus beseen that pointer 35 is positively re strained from contact with or close proximity to the platen, except at substantially the moment when the pointer 35 is needed to in? dicate the printing point and line. Unnecessary contact with the platen and consequent blurring of the work are therebyavoided, as is likewise any obstruction on theplaten connected with the paper-feeding or otlier nieehr It will thus be seen that the spring 35 the swing of theplaten carriei' to force the indicator or pointer 25 away lrom and at anit will l'ur- It will.

therinore be understood that with a shit-tin platen the indicator or pointer serves to indi cate the printing-point and the printing-line whether the printing istaking place in small or in capital letters-that is,in lower or upper case. Either of these features may be employed. independently of the other.

While I have illustrated my invention in connection with a Remington No. (3 typewriting machine, it will of course be understood that it may he applied to any type-' writing machine wherein it may be found available to employ the essential elements ol I departing .faaare my invention, and, further, that various con-' structional changes may be made without from the spirit of my invention.
