WILLIAM ALLAN DYIER, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE SMITH PREMIER TYPEWRITER COMPANY, OF SYRACUSE, NEW YORK, A CORPORA- TION OF NEW YORK.

TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Feb. 27, 1912.

To all 'whom 'it may concern.

Be it known that I, VILLIAM ALLAN DYER, a citizen of the United States, and resident of Syracuse, in the county of Onondaga. and State of New York, have invented certain new and useful Improvements in Type-iVriting Machines, of whichthe following is a specification.

My invention relates especially to paper feeding mechanism for typewriting machines and has for its object to provide improved devices of the class specified.

More specifically my invention resides 1n an improved paper finger contrivance.

As heretofore constructed paper lingers have heen mounted to slide bodily lengthwise of the platen and have also been adapted to be moved to a limited extent transversely of the platen toward and away from the surface of the platen or the paper thereon. In some instances, for example where manifold work is being done and the paper lingers are cooperating with at least two sheets of paper and a carbon inlay, it has usually been the custom when making erasures to turn the platen forward by hand, thereby advancing the paper until the line to be corrected has been fed forward out of the control of the paper fingers. This enables the outer sheet and the carbon to be turned back from the platen, uncovering the inner sheet so that the same may be corrected, an operation which was impossible so long as the paper remained in control of the paper lingers. After the erasure has been made it is necessary to turn the platen backward and retract the paper so thatwriting may be resumed at the point where it stopped prior to the correction. Owing to the tendency of the sheets to creep or move relatively to each other during this back and forth feeding, they sometimes get out of register, causing an irregular spacing of the lines on the under sheet or sheets. Moreover, in some of these prior constructions where no erasing surface either on the platen or elsewhere is conveniently disposed beyond the paper fingers, it is impracticable to advance the sheet for correction by turning the platen. In such a case when erasing is to be done it is necessary with paper fingers as heretofore constructed to move said paper lingers bodily away from each other toward the ends of the platen until they free the paper so that the outer sheet or sheets'may be turned back to expose the inner sheet or sheets. Then after the erasures have been made the paper ngers must be re-adjusted before the writing can be reentirely the written part of the same, enabling it to be drawnV back from the platen sheet by sheet to expose the characters last printed; and this without altering the points of connection between said paper fingers and their support.

To the above and other ends my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

In the present instance the improved result is achieved by pivoting each paper fmger or guide on its support in such a way that it may be swung laterally outward to ward the adjacent end of the platen and away from the middle of the'paper and then locked temporarily so that the operator may conveniently make erasures and manipulate the sheets. In my companion application Serial No. 499,376 filed June lst, 1909, I achieve the result sought in another way, that is, by so constructing the paper finger support that saidV support and the paper finger or fingers thereon may be moved bodily away from the platen so as to leave entirely free the advance portions of the paper.

One form of my invention is illustrated in the accompanying drawings applied to a No. l0 Smith Premier typewriting ma-` chine but it is to be understood that the nature of the invention is such that it may be readily adapted to other styles of writing machines.

In the drawings, Figure 1 is a fragmentary front elevation of the platen and platen carrier of a No. l0 Smith Premier typewriting machine embodying my invention, parts of the machine being omitted and parts broken away. Fig. 2 is a top plan view of the platen and the paper finger supporting rod, showing the paper fingers swung outward in abnormal position. Fig. 3 is a transverse vertical sectional view of the platen and platen carrier taken about centrally, the support of the platen carrier and a part of the top plate also being sho-wn, parts being broken away. Figs. t and 5 are vertical sectional views taken transversely of the platen and showing one of the paper fingers in differentabnormal posit-ions, certain parts in Fig. 1 being broken away for the sake of clearness. Figs. 6, 7 and 8 are perspective views of details of my improved construction.

Referring first to Fig. 3 vthis shows the top plate 1 of the machine from which rise standards 2 (one of which is shown) supporting a grooved track-way 3. Anti-fric` tion balls 4 cooperate with the grooves 1n the track-way and with the angularly bent portions of a slide bar 5, said slide bar at its ends carrying end bars 6, the end bars and slide bar being comprised in the carriage truck. The platen carrier or frame comprises bars or rods 7 and 8 extending lengthwise of the platen and located respectively above and below the same, said rods being connected by parallel end bars or pieces 9 and 10. Arms 11 extend rearward from the vend bars of the platen carrier and carry lateral studs 12 which engage in openings or seats in the carriage truck and on which as pivots the platen carrier may be tilted. Arranged inthe platen carrier is a platen 13 from the ends whereof extend axle portions 14 which engage seats or depressions 15 formed in the end bars 6. The platen is or may be equipped with the usual or suitable feed rollers 16 and 17 arranged respectively at the rear and front of the underside of the platen, said feed rollers being indicated by dotted lines in Figs. 3 to 5. A paper plate or scale 18 of the usual or suitable construction is arranged at the front of the platen and below the printing line thereon, said plate extending lengthwise of the platen and being yieldingly supported. The usual or suitable paper table and paper apron or deflector (not shown) are provided.

The parts thus far described are not my invention and need not be set forth in greater detail.

The paper is introduced into the machine at the rear and fed over the paper table and down behind the platen between the same and the feed roller 16, being guided by the paper deflector or apron forward to the roller 17 and thence upward between the platen and the paper plate or scale 18, after which it is brought into cooperation with certain paper controlling and guiding devices usually termed paper fingers. Commonly two paper fingers are provided but one or four or any desired number may be employed, The paper fingers may be and preferably are mounted on the upper frame rod or bar 7 which serves as a support for said fingers. Each paper controlling and guiding device or paper nger contrivance comprises a carrier part or sieeve 19 which surrounds and bears on the rod 7 and is lslidable lengthwise thereof. The details of one of these sleeves, the sleeve ofthe righthand paper finger in the present case, are shown in Fig. 7 which is a perspective view from the rear. The sleeve is provided with a ange 20 which is formed with a rounded projection or lug 21, said lug engaging in a groove 22 formed in the lower rear side of the rod 7 and extending lengthwise throughout the same. The lug 21 prevents rotation o-f the sleeve on the rod 7 but permits endwise movement of the sleeve therealong. The flange 2O Vis formed at one end of the body portion by the sleeve and from the other end of said body portion extends a portion 23 slightly less in diameter than the body portion and forming a shoulder at its junction therewith. The reduced portion 23 is formed with a longitudinally extending slot 24 which registers with or opens into the groove or cut-out 22 in the rod 7. Atits end opposite from the body port-ion 19 the portion 23 is further reduced as indicated at 25 to provide a seat for a flange 26. This construction enables the paper finger proper and its carrier to be mounted on the sleeve between t-he flanges after which the fiange 26 is driven on to its seat or otherwise secured in place.

The reduced portion 23 of the carrier part or sleeve provides a bearing for a second carrier part which carries the paper finger proper. The last named carrier part is clearly shown in Fig. 6 and also appearing in most of the other views, and is a blocklike member comprising a hub por-tion 27 and a short extension 28 therefrom. The hub portion is formed with a bearing opening 29 and surrounds and bears on the reduced end 23 of the sleeve 19 and is held from endwise movement thereon by the shoulder on the sleeve'and by the fiange 26. The hub 27 is cut away to provide a mouth or opening 30 into the bearing opening 29, said mouth being located just at the rear of the extension 28. Normally said exten sion projects at an angle upward and rearward from the rod 7 as shown in Fig. 3. The extension 28 is formed with a transverse opening which provides a bearing for a pivot pin 31 shown detached inFig. 8. The pivot pin is provided with a head 32 and its end is reduced and squared as indicated at 33. .The head 32 is oblong in shape,- the two longer sides being straight and parallel. The pivot pin 31 enters its bearing opening in the extension 28 from the under side of said extension, and normally one of the longer sides of the head 32 is close to and parallel with the mouth 'of the opening 29, lying just outside said mouth. The thickness of the head 32 is slightly less than the width of the mouth 30 so that while normally the adjacent side of the head practically covers said mouth, yet when the pivot pin 31 is turned on its aXis as presently to be described, one of the end portions of the head 32 is adapted to pass through the mouth 30 and into the opening 29. Normally, however, the pivot pin is prevented from being turned in this way by the face of the reduced sleeve portion 23 forward of the slot 24, as will be understood from a considerationv of Fig. 3. The squared end portion 33 of the pivotpin 31 projects beyond the upper face of the extension 23 and carriesan arm 35, said arm as shown in Fig. 2 being provided at its upper end with an inwardly extending rounded enlargement or head 36 which is formed with a square hole into which lits the squared end 33 of the pivot pin. A short headed screw 37 screws into a threaded opening in the squared end 33 so that the head 36 is confined between the head of the screw 37 and a shoulder formed at the junction of the squared portion 33 with the body of the pivot pin 31. The construction is such that the arm 35 and the paper nger proper carried thereby and presently to be described form practically one piece with the pivot pin 31. The pivot pin serves as an aXle for the arm 35 enabling said arm and the paper finger proper to be turned or rotated under certain conditions on and independently of the rotary carrier part.V From the inwardly off-set portion 3G the arm 35 is straight and inclines at an angle downward and forward over the top of the platen (Fig. 3), its lower end portion being curved or off-set inward toward the middle ofthe machine (Fig. 1) terminating in an enlargement or block 38. The enlargement is formed with a slot 39 which receives a pressure roll 40, said pressure roll being pivot-ally mounted in the sides of the slot. A knob or finger piece 41 is secured to the enlargement 33 and projects forward therefrom. A downward projection 42 on the enlargement 38 has secured to its under side as by rivets 43 the guiding portion proper of the paper finger which may be of sheet metal. and comprises two guide fingers or extensions, one, 44, extending down over the paper scale 1S, and the other, 45, extending inward toward the middle of the machine and slightly upward as best appears in Fig. 1.

The member comprising' the extension V23 and the hub 27 is constantly tending to turn forward vby reason of the pressure imparted to it by a wire spring 46 which is coiled around the body portion of the sleeve 19 and has one of its ends secured in a hole in the flange of said sleeve, the other end being including the sleeve 1 9 in any position to' which it may be adjusted lengthwise of the rod 7. Then the knob 41 is pushed upward the paper fingers proper will be swung away from the platen, the extension 23 turning rearward to permit of this movement; and then the entire paper finger contrivance may be slid along the rod 7 and re-adjusted in any desired position.

As shown in the drawings there are two paper finger contrivances each constructed in the manner described above in detail and differing only in the respect that one isa right-hand contrivance and is olf-set toward the left while the other is a left-hand contrivance and is off-set toward the right, the off-set portions of the two contrivances eX- tending inward toward each other. Let it be assumed that the two contrivances have been properly adjusted to coperate with the side portions or margins of the paper which is to be written on, and that a manifold packet of three sheets including an inner sheet a, a carbon inlay Z9 and an outer sheet 0, has been fed into the machine in the manner heretofore described. As the writing takes place and the sheets are advanced together line by line in the usual or any suitable manner, the leading end portions of the sheets will pass upward from the paper plate 18, the side margins of the sheets passing under the

guide fingers

44 and 45 and the pressure roll 40 as well as under the lower' inwardly curved or off-set portions of the arms 35. Thence the sheets advance between the straight portions of said arms 35 and back over the top of the rod 7, until said sheets are in the positions shown in Fig. 1. Suppose at this time it is desired to make an erasure. By means of the knobs 41 the paper fingers are swung upward from normal position shown in Figs. 1 and 3 to the position shown in Fig. 4. During this movement each paper finger proper and the associate arm 35 will swing togetherwith the rotary carrier part on the reduced portion of the stationary carrier part or sleeve 23 as a bearing, the movement of the parts being in parallel planes transverse of the axis of the platen and of the supporting rod 7. As the paper fingers are swung upward a slight outward pressure toward the adjacent ends of the platen is maintained against each of the knobs 41. The movement of the paper fingers due to this outward pressure is revplished by sisted initially by the surface of the sleeve portions 23 which serve as stops for the contiguous straight faces of the heads 32. Vhen, however, the paper fingers have been swung upward to the point where the heads 32 are in regist-er with or opposite to the slots 24, as shown in Fig. 4, then the resistance to the turning of the heads 32 and connected parts is ended and the outward or lateral pressure on the knobs 41 will cause the paper ngers to swing laterally7 outward toward the adjacent ends of the platen about the axes of the pins 31 as centers and in planes parallel with the axis of the platen,

lthe end portions of the heads 32 of said pins passing through the mouths 30 into and through the slots 24 and entering the groove 22 in the rod 7 as illustrated in Fig.

The lateral movements of the paper lingers will be limited by stop pins 47 projecting from the under faces of the extensions 28. Each stop 47 will be engaged by a portion of the associate head 32 at t-he opposite side of its axis from the portion which enters the groove 22. But the consequent arrest of the lateral movement of each paper finger takes place only after said paper fingers have been swung laterally outward entirely beyond the side edges of the paper to the positions illustrated in Fig. 2. If, now, the operator releases the paper lingers they will be maintained in the Fig. 2 position by reason of the fact that though the springs 46 are tending to swing said paper lingers forward about the axis of the rod 7 as a center, this tendency is resisted by the engagement of the head 32 with the upper sides of the groove 22 and the slots 24, the

parts

22, 24 and 32 constituting locks or latches. lith the paper fingers in the positions shown in Figs. 2 and 5 it will be obvious that the portions of the sheets above the paper plate 18 are entirely free and that these portions may be separa-ted and drawn forward singly, or two at a time as shown in Fig. 5. lith the sheets inthe relation shown in said Fig. 5, the printing line on the under sheet a, which line is a short distance above and parallel with the upper edge of the paper or scale plate 13, will be exposed so that. an erasure may readily be made in the printing line, the platen serving as a backing. After such erasure the carbon inlay may be turned upward and backward against the sheet a and then a backing sheetmay be inserted directly behind the outer sheet c so that the corresponding erasure may be made thereon. This being accomplished the backing sheet may be withdrawn and the paper lingers may be restored to .normal position. In practice, this may be accoma slight inward pressure on each knob 41 sufficient to swing the paper lingers inward until the heads 32 disengage from the grooves 22 and slots 24, after which the springs 46 will operate to swing the paper lingers downward into contact with the paper and the writing may thereupon be resumed. When the paper Enger contrivances are in normal position lateral movement of each arm 35 in one direction is prevented by the co-action between the head 32 and the sleeve portion 23, while lateral movement in the opposite direction is prevented by the co-action between the head 32 and the pin 47. Moreover at all times the pins 47 cooperate with the heads 32 to prevent excess pivotal movement of the paper lingers inward toward each other.

By the operations above described the different sheets of a manifold packet or set may be freed for separate manipulation for the purpose of making erasures or for any other desired purpose without the necessity either of turning the platen forward and backward and consequently advancing the paper forward and backward, or without moving the paper finger contrivances laterally to new positions with the consequent necessity of re-adjusting them in the old posit-ions after the erasures have been made.

It will be understood that though the motion of the paper fingers from normall position to the Fig. 2 position has been described in two steps, yet these steps are not separated by an vappreciable interval of time but merge one into the other so that the releasing and locking operation for each paper finger is practically a continuous one and occupies but an instant of time. It will further be understood that in the No. 10 Smith Premier typewriter it is desirable prior to making erasures to tilt the platen and platen carrier upward and backward on the pins 12 as centers in order to raise the printing line out of the way of certain of the carriage feeding and ribbon devices (not shown). This tilting operation is explained in detail in the application of Alexander T. Brown liled April 25th, 1906, Serial No. 313,603. In the present instance the tilting of the platen may be accomplished by pressure on one or both of the knobs 41 and follows the outward or lateral swinging of the paper lingers to the Fig. 2 position. At the moment of arrest of the paper lingers by the engagement of the heads 32 with the stop pins 47 it will be apparent from a consideration of Fig. 2 that pressure against the knobs or linger pieces 41 is substantially rearward; and this rearward pressure after the lateral swing of the paper lingers has been arrested will operate to lift or tilt the platen.' The result is that in such constructions as the present one, the throwing out of the paper lingers andthe tilting of the platen may be accomplished at what is really a single continuous operation.

The specific constructions of the guide lingers and the pressure rolls are not claimed by me; but I believe that the means which enables the paper lingers to be moved away from the surface of the platen entirely out of the path in which the paper or work sheets are swung toward and away from the platen is new with me and I desire to claim it broadly as well as to claim the specific Vconstruction by which in the present instance the improved results are accomplished.

It will be observed by my present invention I combine with the platen a paper finger contrivance comprising a paper guide or guiding part or finger and means for enabling said part to be moved away from the surface of the platen entirely out of the path in which the portion of the paper that has passed the printing point may be drawn away from the platen so as to expose the printing` point or the underlying sheets, the set position ol the contrivance remaining unchanged; that in the present instance Vafter the paper finger or lingers has or have been moved then the advanced portion or portions of the paper may be pulled away from the platen until arrested by the paper plate or scale; that in a front-strike type writing machine like the present one the paper plate is arranged parallel with the printing line and below the same while the support or rod on which the paper linger eontrivance or contrivances are mounted is arranged above the platen; that the paper guiding part or paper finger is pivotally mounted and may be swung on its pivotin planes parallel with the axis of the platen; that when two paper lingers are employed they may be swung laterally away from each other on their supports; that in the present instance in moving the paper fingers away from the platen they are first swung in paths or sets of planes which are parallel with each other and transverse of the platen axis, 'and are thereafter swung in planes at right angles with said parallel paths but parallel with the platen axis; that the movement of the paper lingers away from each other is also substantially lengthwise ot' theA paper plate; that each of the paper finger eontrivances in the present instance comprises a carrier and a paper guide or linger pivoted thereon; that the carrier is a two-part carrier, one of the parts being mounted to rotate on the other part which latter as here shown is a slidable sleeve; that thetwo carrier parts are connected by a spring; that the paper guide or finger is pivoted on the rotatable carrier part; that said paper guide is adapted to rotate with said rotatable part and also independently thereof; that normally said paper linger `or guide is held positively from independent rotation on said rotatable carrier part; that means are provided for locking the paper lingers lin abnormal position; that said locking means are normally inoperative; that is, they cannot lock the paper lingers out owing tothe fact that the locking parts are in normal relations such that cooperation between them can not take place for the purposeintended; and that as a prerequisite to rendering said looking means eli'ective itis necessary to swing the paper finger in two direc tions at right angles to each other.

The term papel' finger employed in the claims is used in its broadest sense and is to be construed as covering any paper controlling or guiding device for leading or directing the paper in a desired direction; and under this delinition a roll would be ineluded.

Various changes may be made without departing from the spirit and scope of my invention. Y

That I claim as new and desire to secure by Letters Patent, is z- 1. In a typewriting machine, the combination with the platen7 of a paper linger contrivance comprising a support and a paper guide partly surrounding the platen and cooperative therewith at both sides of the printing line, said paper guide being pivoted on said support and inwardly oli-set from its pivot toward the middle of the platen and said paper guide being movable independently of its support outwardly away from the middle of the platen and lengthwise of the platen.
