FRANK A. YOUNG, OF SYRACUSE, NEW YORK, ASSIGNORTO THE MONARCH TYPEWRITER COMPANY, OF SYRACUSE, NEW YORK,A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

Application filed July 22, 1905. Serial No. 270,833.

To all whom it may concern.

Be it known that I, FRANK A; YOUNG, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Type-Writing enabling paper, and more especially envelops, cards,

stiff paper, ete.,. to be guided against the platen and held inv close contact therewith, and so that the worksheet may bewritten upon close to the top and bottom other parts shown in said figure. Fig. 3 is a perspective view of the combined card guide or holder, printing edges.

My invention also relates to printing point indicators and to line guides.

To these and other ends, the invention resides in per tain features of construction, combinations of devicesand'arrangements of parts to be hereinafter mor futlyf set forth and particularly pointed out in the claims.

1n the accompanying drawings, Figure 1 is a frag mentary vertical sectional view, taken about centrally of the machine and from front to rear thereof, and showing so much of said machine as 'isnecessary to a clear understanding of my invention. Z is a fragmentary front elevation of the upper portion of the machine, showing certain parts not shown in Fig. 1, and omitting point indicator and line guide. Fig. 4 is an enlarged top plan view of my device shown in Fig, 3 and illus ftrating my improved card guide and holder and its I guide or finger.

supporting'bracket. Figs. 5 and 6 are enlarged detail views showing the means for regulating the pressure of the card holder or guide. Fig. 7 is anenlarged fragmentary detail view showing the mode of coit'aperation between the card holder, etc, 'and the marginal paper The invention is shown as appli ed to a machine havport a top plate '2 which sustains brackets 3 to which latter are secured top and-bottom guide rails 4.- Antifriction balls 5 cooperate with the rails 4 and also with a grooved back bar 6 of a platen carriage 7 wherein-is rotatably mounted a cylindrical platen 8, which may be moved longitudinally step-by-step in the printing direction and line spaced and returned in a known manner. 7 At the front of the plateng secured to arms 9, fixed to the platen carrier, is a scale bar'lO provided with two scales, the scale-along itsupper edge being the platen Specification of Letters Patent.

Patented Oct. 22, 1907.

.scale and the scale along riage scale.

Arod 11 is supported in the sides of the platen carrier, and slidably mounted onsaid rod are side or margin guides or paper fingers 12'which move with the platen and are adapted to control the side edges ofthe paper. The end of each margin guide or paper finger 12 is bent forwardly and formed with a double cam 13 for a purpose its lower edge being the carpresently to be explained.

A support or bracket comprising end or side members 14, joined by a cross barl5, is secured centrally of the machine to the under side of the top plate by meansof screws 16 which pass upward through perforations in the cross bar 15 of the bracket and take into threaded perforations in the top plate.- The front edges of the side members or portions 14 are formed with-depressions orrecesses 17 and secured in these recesses by screws 18 (as seen in- Figs. 1 and 2) is a vertically disposed bracket 19 which'giiides and supports a ribbon vibrator 20. The ribbon vibrator normally maintains theribbon below the printing line and is connected with a known construction of vibrating mechanismv (not shown), whereby said vibrator is moved upward in the guide 19 at printing operation to interpose the ribbon between .the printing point on the platen 8 and any one of a se-.

connected by a link 24 with a known construction of type bar actuating mechanism. I

A short'rod 25 has its ends secured in the-side portions 14 of the central stationary, support or bracket and mounted upon this rod is'a device 2 6, which, for convenience of description, will be hereinafter referred.

to usually as a cardholder or pressure device; but it will be understood also from the following description I that this device 26 is so made that it serves not only as a card holder but as a printing point indicator and as "a line guide. The said contrivance'26 is preferably at 33. Scale marks or graduations are provided at 34' on the upper portions ofthe wings 31 ori'ithe side of the operator. Midway between theupwardly extending arms 28 the cross bar 27,, is provided with an upwardly andrearwardly extending indicator or pointer 35, which is adapted to cooperate with the carriagescale at the bottom of the scale bar 10. The ends of the cross bar 27 of the'card holderlorming tabs or ears 36, which are perforatedat 37 for the passage of the rod 25 which pivotally supports the card-holder in the machine. A coiled spring 38 surrounds the rod 25 and has one end bearing against the cross piece 15 of the central bracket and the other end bearing against the cross bar 27 of the card holder 26, below the pivot rod 25, as best appears in Fig; 1. The

coiled spring'38 constantly tendsto press the upper part of the card holderfor guide against the front face of the'platen 8. g g

39 is a horizontally disposed locking lever which at its'rear'end' my be arranged upon one of the fastening screws .16 or may be providedwith a separate pivot. The forward end of said lever 39 extends through a hole 0in the ribbon guide bracket 19, The. right haZnd edge of the locking lever 39 is shouldered or ciitaway at 12,-forming a corner which co-ac ts 'withthe beveled edge 30 on the card guide and the portion 43 of the lever projecting through the hole 40 serves as a finger piece Ilor moving the lever about its pivot. Fig. 1, the lever may be provided with a downwardly extending 'pin'44 which may be employed in lieu of the part 43 for moving'the said lever.

The card holderor guide',it will be observed, is fixed centrally of the machine, being pivotally supported on tho ro'd25'an'dis positioned between the ribbon vibrator and its guide on theone side and the platen on the other, the arrangement being such that the normal operation of-theplaten and the ribbon vibrator are not .interiered'with. When the latch or lever 39 is inthe position shown in Figs. 2, 4 and 5, the pressure device or card guide is pressed against the platen only by the spring 38 and when so pressed; serves to exert agentle pressure'which is sufficient to assist in the-feeding of ordinary paper or the like. In this position it will be noted that the lever 39 stands out of contact with the arm 29 of the-card'guide or holder, as best appears in Fig. 5.- This figure and the-companionFig. 6 show the pivoted latch or lever -39 in top plan and showa section of the card guide or holder taken on a plane represented by the line it in Fig. 3. Whenit is desired to write upon cards, env elops, thick paper or the like, the latch or lever 39 is. swung rightwardly about its pivot fromvthe position indicated in Fig. 5 to that indicated in Fig. 6. When thelever is thus shifted, the shouldered portionAZ engages the beveled edge 30 ,of the lug 29 and cainsjthe latter outward or towards,

theoperator, thereby causing the upper part of the card 'guide, in contact with the platen, to be brought into and maintained in positive or locked engagement with the latter.

,The card a or other'substance to be written on is introduced into the machine and fed aroundthe platen by means of the usual mechanism. The card is guided I and held near its side edges by the marginal guides or fingers 12, but there is always a tendency more or less markedot the card,to stand awafyirom the platen or 5buck1e ,,as it is called, between the margin guides, and this tendency istparticularly pronouncedwhen the top or'bottom oi the card is ator in the vicinity of the printing point. This .buckling is increased as the are bent 'rearwardly,

As indicated in I used separately and apart from the side guides.

distance between the margin guides is increased, the space between'the guides usually depending on'the length of the card and that of the line to be written thereon. To prevent the buckling and to hold the card firmly against the platen at the printing point is one of the objects of this invention, there being suflicient give or spring in the pressure device to permit 1 of'tl e passage of the work sheet between the platen and the device, while at the same time the positive pressure on the device forces the work "sheet close against the platen, causing it to conform to the curvatiire oi the platen at the printing point and thus avoiding any shadowing of the type impressions.

The pressure device 26, it will be observed, is, in

effect, a lever frame or a three-armed lever fulcrumed on the rod 25 and having one of its arms, the lug 29,, ex

' tending downwardly and the other arm, which is a twopart arm comprising the parts 28 and the associate parts 31 extending upwardly. When the locking lever 39 is moved from inoperative to operative or locking posi,

tion, it swings the lower arm of the lever 26 outward. The upper armoi the lever'or lever frame 26, however, is already in contact with the platen against which it is pressed with a comparatively gentle force by the spring 38. The result of the outward movement of the lower arm of the lover or pressure device 26 is to press the upper part of the lever with still greater force against the platen. When locked by the locking lever 39 the upper ends of the pressure device or lever 26. are prevented from moving by the platen and the lower 96 part or arm 29 is prevented from moving by the shoulder 42 of the locking lever 39. Theonly way that the paper or card can pass between the platen and the pressure device is by the latter itsel'f yielding or giving between the upper ends of the wings 31 and the lower 100 ends or roots of the parts 28. In order, therefore, to

permit ol the feeding of the paper between the pressure device and the platen the internal structure of the pressure device must bealtered or changed.

The employment of the pressure device in conjunction with the side or margin guides while of course preferable, is not essential and the invention may be The pressure device 26 is so arranged that its upper ends exert a pressure against the surface of the platen to- .110

wards its axis and such that though the card be quite thick and resilient it may be Written upon even at the extreme edge of the top (Fig. 1) or of the bottom (Fig. 2), in which last position it will be observed the Writing occurs after the bottom edge has escaped or passed 1'15 from beneath the-upper edge of the scale bar 10. The

scale-bar 10 ordinarily serves to hold the card against the platen and it would spring away from the surface of the latter after passing from beneath the scale bar. but for the restraining'influence oi the card guide.

while the pressure device or card guide is thus positively maintained locked in engagement with the platen, a movement of the platen carrier across the top plate brings either of the margin guides 12 in contact with the side portions 31 of the card guide, the 12a cam face 13 of the margin guide 12, contacting with the side portions 31, will bend or cam the associate arms 28 in-succesgon forwardly away from the platen far enough to permit the margin guide 12 to readily move past. The co-action between the parts is repre 130 v sented in Fig. 7 It will be noted from an inspection of said figure that while the right-hand side portion 31 and arm 28 are shown cammed forward, the corre-' sponding left-hand parts are undisturbed. This operation of the parts is possible because though the arms 28 are both integral with the cross bar 27, said arms I have sufficient spring or resiliency to permit of their i being moved independently of one another, so that the cam face 13 of one of the side guides 12 will act to cam one of the'arms 28 away from the platen and permit it to spring back towards the platen before said cam edge. 13 affects the other arm.

If the side edges of the card or work sheet a are so far uncontrolled by the side guides 12 as to stand away from the face of the platen, said edges will, assoon as they are brought during the movement of the platen into contact with the central card guide, be forced by the latter close against the surface of the platen. Thisop- I eration will be brought about by reason-of the sloping or inclined outer edges 32 and the outwardly or forwardly bent inneredges 33 of the central guide. The outstanding edge of the-card or sheet, after contacting with one of the outer edges 32, will, during further longitudinal movement of the platen, be forced against the latter by the camming action of said outer edge 32 so that the card will finally be passed properly between.

the central card guide and the platen without mutilation. After passing from one side of the central card I guide, if the card should again spring away from the platen, the side edge will be caught by the outstanding edge 33 of the other side of the central guide and will be guided or deflected back against the'platen and pass on, parallel with the card guide'and between it and the platen.

The upper edges 41 of the guide or pressure device 26 are arranged preferably adjacent the lower edge of.

the printed line so .that said edgesserve as a line indicator or guide, and the scale marks 34 at said upper edges register with the platen scale on the upper edge of the scale bar 10, and may be used as a platen scale,

while'the narrow spacebetween the inner edges 33 of the guide, which space is indicated in the drawings by. the reference numeral 45,"accurately indicates the printing point on the platen.

The member 26 maybe regarded apart from its paper controlling functions and solely as an indicating device for indicating the printing point or for indicating or finding the printing line or for serving as a platen,

scale or for exercising these indicating functions con jointly. When it is desired to make a correction on the work sheet which has been alreadywritten and removed from the machine, the work sheet may be replaced in the machine and fed around the platen in the usual way until the bottom of the line in which the correction or change is to be made registers with the elongated edges 41. The sheet may then be adjusted laterally, or longitudinally of the platen, until the letters in the line register with the graduations or scale marks 34 at the upper portion of the" member 26. The platen may then be proved longitudinally until the point where the correction or insertion is tobebegun'isin. register with the space or opening 45 between the edges -33." An insertionmaythen be printed with the result that the letters will 'be in proper position. The indicating devices provided by the member 26 for finding the line, adjusting the printed line in proper register laterally and for finding the proper point in said line have the advantage of all being in close proximity to the place where the adjusting, finding and arranging is performed, and therefore enable this adjustment to be done with great accuracy. 1 i I The locking lever may be maintained in operative position when ordinary paper isto be written on, although the strong pressure provided by the locking lever is not absolutely necessary and the pressure'given,

by the spring 38 would be sufficient for such ordinary work. 7 For some classes of work, however, notably work in which provision is made for'writing a number of copies simultaneously by interposing carbon sheets between the work sheets, the locking lever 39 should be swung leftward to release the pressure device, as otherwise there would be a tendency to smudge the sheets, owing to the strong pressure against the carbons.

It will be noted that I have provided a pressure device for guiding, controlling, feedingand holding the near the printing point; that I provide means for forcing the pressure device into a positive or locked en-' for holding and guiding the paper; that the pressure device comprises two resilient independent fingers,

each composed of a spring arm 28 and a side portion or .85 card or work sheet in contact with the platen at and ear 31, which side portion has an inside and an outside camming edge; and that the device has indicating functions also.

While for the sake of brevity the invention has been frequently referred to herein as a card holder, card guide, etc., it is to be understood, of course, that the invention isaipplicable not only to cards but to any other form of work sheet, suchas envelops, paper and regardedas an indicating device. Variousclianges inthe'details of construction the arrangement-of the parts may be effected without departing from thescope of my invention.
