Beit known that I, HIRAM JOSEPH HALLE, a citizen of the United States, residing` at Cleveland, in the county of Cuyahoga and vSta-te ofOhio, have invented a new and use-.

ful Extensible Platen for Type-Writing Ma-j chines, of which the following is a specification.

My present invention relates to a platen for type-Writing machines of that class which print upon a sheet supported in a flat or spread-out condition upon a flat stationary platen over which the machine is movable both laterally and longitudinally. This type of machine, exemplified in Patents Nos.` 562,625 and 573,868 of R. J. Fisher, is generally intended for writing in books or on loose sheets and for making up records and reports and copies thereof. Theflat plateniseq'uipped with main tracks or guides designed for the support of a machine-frame movable longitudinally of the platen 'or in the direction of line-spacing and supporting a carriage movf able on the frame transversely of the platen andequipped with Writing mechanism. y These' tracks or y guides supporty the machine' for' movement to'any desired position opposite" the printing area and are .also extended loe-g youd theV printing area to support the machine outside of orf beyond thewritinglsurface an'd over a platenextension.l This provision for` supporting' theniachine either directly above,`

or beyond the printing area constituted the broad novelty disclosed in my Patent No. 621,660, dated March 21, 1899, and was intended to facilitate the -displacement of the machine from the printing area forthe pur pose of displacing, replacing, or adjusting the Work sheet or leaf. The retention of the work sheetor element in its proper position is facilitated byvworkholding means associated with hinged track or guide sections longitudinally coextensive with the printing area of the platen and movable away from the platen to permit the displacement or replacement ot the work element after the machine has been moved back upon the fixed sections of the tracks or guides, and thereby positioned above the platen extension beyond sys To this endvthe invention contemplates the equipment of the platen with a displaceable extension normally depending vertically from the rear end of the normal platen extension,'but capable of being presented in the horizontal plane of the platen when an extension of the latter is desired This platen extension when in its horizontal position is designed as a machine-support located beyond the printing area of the platen, and is therefore provided with tracker yguide seca tions constituting continuations of the tracks V'orV guides of the platen proper. platen is elongated by the elevation of the "displaceable extension, the printing area is :increased by utilizing the normal platen eX- 'When the tension as a continuation thereof, and pro- Vvision is therefore made for rigidly connecting the front and rear sections of the tracks or guides at the hinge-joints thereof and for swinging said tracks from an axis located adjacent to the front edge of the drop extension.

Other objects subordinate to that stated and various novel features of construction will appear during the succeed/ing description ot the illustrated embodiment of my invention. Y

In the accompanying drawings, Figure lis a plan viewof av platen constructed in accordance with my invention, the extension being shown in its elevated or horizontal position. Fig. 2 is a longitudinal sectional view of the platen and supporting-stand therefor, the machine being indicated above' the extension in dotted lines and the tracks or guides being similarly shown in their elevated positions. Fig. 3 is a side elevation of the platen with the extension dropped down to its vertical position and the tracks or guides elevated, the supporting-stand for the platen and the machine located above the normal platen extension being `indicated in dotted lines'. Fig. 4 is a det-ail view, in bottom plan, showing the hinge connections of the platen and the drop extension. Fig. 5 is a plan view offa portion of the platen and its equipment.. Fig. 6 is a longitudinal section on the line 6 6 of Fig. 5. Fig. 7 is a detail View of one of the track-locks, parts being shown in section and other parts broken away. Fig. 8 is a detail perspective View of the subject-matter of Fig. 7 with the parts in dierent positionsn Fig. 9 is a transverse sectional view on the line 9 9 of Fig. 5 and with the top and bottom sheets in place. Fig. 10 is a bottom plan View of the front end of the platen, showing the track-elevating mechanism, the front carbon-carrier, and complemental-y parts. Fig. 1l is a detail perspective view of one of the card-guides and the connected end of one of the IieXible guardstrips. Fig. 12 is a detail sectional view on the line 12 12 of Fig. 5. Fig. 13 is a detail perspective View showing the mounting of the billing-strip. Fig. 14is a detail sectional elevation of the lower end of the drop-frame, and Fig. l5 is a detail perspective view'of the detachable supporting-bracket for the track-elevating device.

It has been stated that this invention owes its existence to the demand for a platen adapted for various kinds ot work. While, therefore, the invention, so far/as the presentapplication is concerned, comprehends only those instrumentalities whereby sheets of different lengths are accommodated, l have nevertheless illustrated in the accompanying drawings a platen constructed in accordance with theinvention and equipped with various devices which facilitate the retention and manipulation of dierent classesof work elementssuch, for instance, as the leaf of a book, acard, a folded bill, an ordinary letter-sheet, and the bills and subjoined sales-sheet employed in those billing systems which contemplate the entry upon the sales-sheet of successive carbon copies of the bills. It should be understood, however, that this complementary equipment of the platen together with those supplemental devices for properly positioning a carbon element or web to facilitate manifolding are not herein claimed, although they involve many features of patentable novelty.

,'lhey are illustrated and described merely port or stand supporting the platen 2, comprising, as usual, a metallic base 3,covered by a rubber or other suitable writing-surface 4.

It is sometimes desirable to elevate the platen for the purpose of facilitating the manipulation of the leaves of a book when the device is employed in connection with this character of work element, and for this reason said platen is hinged at its rear end, like the platen shown in my Patent No. 621,660, above mentioned.. Instead, however, ot having a direct pivotal connection withl the front end of the platen extension, as in the patented construction, the platen has a hinge connection, as indicated at 5, with what may be termed a drop-frame 6, disposed vertically at the rear end of the platen and supported in any suitable manner.

By preference the frame 6 is provided at its upper endand below the plane of the platen with guide'- rollers 7 and at its lower end with other guide rollers 8, the rollers 7 engaging a rail 9 and the rollers 8 engaging a similar rail 10 The rails 9 and 10 are connected by one or more rack-bars 11 and are designed to be raised and lowered in unison with a.v front rail 12, located in front of the stand 1 and supporting the front end of the platen. The equipment of a stand with these rails for raising and lowering the platen in order to facilitate the use of the latter in connection with the leaves of a book is common, as also is the mechanism (not illustrated) for adjusting the rails vertically.

The specific construct-ion of the drop-frame 6 is beyond the purview of the present invention and 'for this reason need not be described in detail. It is sufficient tostate that this frame constitutes a support to which the platen is hinged at its rear end and which serves t-he additional purpose of a support to whichis hingedly connected, as indicated at 13, an extension 14 of the platen. This hinged connection is preferably effected by forming the drop-frame with a pair of bearing-ears 15, received between similar ears 16, connected to the frontend of the pl-aten extension 14 and constituting bearings for the pintles 17, one of which is indicatedin dotted lines in Fig. 4.

The extension 14 constitutes, when in its horizontal position, a continuation of the platen 2, and while in the present construction it is connected to said platen by an intermediate supporting frame it is evident that it might be otherwise mounted at the rear end of the platen-as, for instance, by being hinged directly thereto. Normally the extension 14 is disposed vertically, as indicated in Fig. 3, but when a platen of addi'- tional or abnormal length is required is supported in the horizontal plane of the platen by a swinging supporting-bracket 18, includinga vertically-disposed bearing-bar 19, having trunnions 20, received within suitable bearings in the top and bottom horizontal members of the drop-frame 6.

i yond the printing area forrthe support ofthe oi' the extension said extension may be lifted.

slightly to disengage the head 2l`from the socket 22, and the bracket 18 may then be swung around to a position at right angles to that shown in Fig. 2 to permit the extension to drop to its vertical position.

The main tracks or guides 23, designed for the support of the traveling machine-frame, extend continuously along the opposite side edges of the platen and the extension 14 and project slightly beyond the front end of the platen and the rear end of the extension.4

These tracks or guides are toothed, as usual, for the greaterportion of their length for engagement With toothed-wheels constituting elements ofthe line-spacing mechanism of the machine and are composed of three sections-*to wit, what may he termed the eX- tension or auxiliary sections 24, rigidly.

connected to the extension let and designed to move therewith, the rear sections 25, whichare normally stationary and are located at opposite sides ofthe normal platen extension, and the front 'sections 26, disposed at opposite sides of the normal printing area of the platen and hingedly connected at their rear ends .to the front ends of the rear sections 25 by hinges 27. Normally the extensionl/i is dropped down at the rear end of the platen, and the machine when not in use is` disposed over .the rear end of the platen, constituting the normal platen extension, and is supported by the rear track-sections 25. That portion ofthe platen lying in advance of this normal platen extension constitutes the normal printing area, and the hinging of the front track-sections 26 is designed to permit their elevation to facilitate the displacement of a Work-sheet from the platen or its replacement or adjustment thereon when the machine has been moved back beyond the normal printing area, as indicated in dotted lines in Fig. 8, the front track-sections 26 being1 connected for movementin unison toward and away from the platen bya transverse bar 28, as usual. This general arrangement of the platen and of the main tracks or guides having hinged sections extending along the opposite sides of the printing area and station- `ary sections for supporting the machine over the platen extension is quite ordinary; but, as has already been stated, the Yprimary object of my invention, so far as the present application is concerned, is to provide for the extension ofthe printing area without dis-I pensing-with a machine-support located be- -moved from the hinge.

lis

machine during the manipulation of the work. For this reason the rear track-sections 25 are hinged at their rear ends, and suitable means is provided for locking the front and rear track- sections 26 and 25 rigidly together in properly-alined positions, so that what are normally the xed and swinging sections of the main tracks or guides become swinging sections disposed along the opposite sides of an abnormal printing area including both the normal printing area and the normal platen extension. When the printing area of the platen is thus extended L o include the normal extension or machine-support, the eXtension let is swung to and supported in its horizontal position to constitute a machine-support for the reception of the4 machine when the latter is moved back beyond the abnormal printing area.

The manner of hinging the rear track-sections 25 is not material so far as the invention in its broader aspects is concerned, since the only requisite is that they be capable of swinging from an axis beyond the rear end of the normal printing area when an extension of such area is desired. Inasmuch, however, as the present construction contemplates the hinging of the platen to permit the same to be swung up in a manner described in my patent'aforesaid, l have shown the track-sections 25 provided at their rear ends with depending bearing-ears 29,7pivotally connected, as

contemplates the extension of one track-section and a device for connecting such extension to the other track-section at a point retion, and one only need therefore be described.

IIO

The locks employed 'i The front end ofv the rear track-section 25 has attached thereto a plate 3l, seated Hush 4with the under side of the track and extended beyond the hinge 27, connecting the front and rear sections. The extended portion of this Aplate is disposed for reception within a recess 32, formed in the under side of the front tracksection 26 and extending from the 'hinge 27, and adjacent to its end is provided with an opening 33 for the reception of a head or pro- -jection 34, which tits-within the opening 33 mounted within a casing 38, formed bybending up and overA the outer side edge of the` plate 31.

When the front tracksection is swung down to its horizontal position in alinernentv with the rear track-section, the head 34 enters the opening 33 in the plate 3l and serves to vhinge 27.

assist in preventing any lateral movement of the track-section in a horizontal direction. When the parts are in this position, the angular end 36 of the latch-bolt 37 will be located in one end of the counter-recess 35, and by moving-said bolt endwise the end 3b` may be slid over the head i4-that is to say, between the head 34 and the bottom of the recess 35-to effect the connection of the front track-section with the extension of the reartrack-section at a point in advance of the This movement of the latch-boltl is facilitated bythe provision at its rear end ofa nger-piece 3S, which may be engaged by the finger-nail in an obvious manner. When the front and reary track-sections are thus locked rigidly in alinement, they obvi-y ously constitute a single swinging track-section hingedat the rear end of the platen or abnormal printing area and capable of movement toward and awayfrom the platen to facilitate ,the manipulation of the. work elements.

We have now seen that the platen is equipped with main tracks or guides comprisingconnected front sections movable toward andvaway from the platen and rear sections located beyond the normal printing area to support the machine while the front sections are manipulated and having hinges located at their rear ends and locking devices for connecting their front ends rigidly with the front` sections, so that the hinged frame, including the track-sections and their connections, may swing upon an axis located beyond the normal axis of movement of said frame when an Itr extension of the printing areais desired. may-be noted, however, that under some circumstances-as, for instance, when comparatively narrow work-sheets are being used-it isnot necessary to elevate both rails, andit` .is therefore within the purview of this invention toconstruct only one rail or track in sections in them anner described. We have also seen that the platen is equipped with an eX- tension retained in a horizontal plane to constitute a machine-support in rear of the nor-v mal platen extension and designed to support the machine at a point beyond the abnormal printing area, including the normal printing area and the normal platen extension y ing area. These machine-stops are preferpoint slightly beyond its frontedge, so that when the drop extension is down' the machine-stops will project slightly above the tracks or guides at the rear ends of the rear track-sections 25 to arrest the machine in the position indicated in dotted lines in Fig. 3. The specific construction of these machinestops 39 is not material, nor is it essential that they be mounted upon the platen extension. lt issuficient if provision is made for the presentation of a machine-stop in position to arrest lthe machine over the normal platen extension or machine-support and for the withdrawal of said stop from such position to permit the machine to travel back upon the drop extension when thelatter is in use. For instance, the extension instead of' being dropped when not in use may be raised to an upright position to' effect itsdisplacement and in such. position would constitute av machine-stop located at the rear end of .the normal platen extension. It would also be possible-to locate thehinge ofthe eX- tension a short distance in rear of its front edge, so that the latter would project upto constitute a machine-stopV when the eXtension is dropped. It is desirable, however, to provide, as in the present construction, for the automatic presentationof the machinestops 39 into the path of the machine when the platen extension 14- is dropped down and for the automatic withdrawalof said stops when the drop extension is swung up, so that .the machine may travely back over the drop extension, Where it will be arrested by the machine-stops 40 in the form of pins or pro-- jections extending from the track-sections 24 adjacent to their rear ends.

Having completed the description of that structure upon which the subjoined claims are predicated, I shall now proceed to describe briely the complementary equipment which renders the platen available for different classes of work. It may be noted at this point, however, that some ofthe features ofthe platen equipment herein shown and hereinafter described were not invented by me. On the contrary, thebilling strips and slidey weredevised by John A. Smith, the card-guides and connected tapes andthe follower-plate having a machine-operatedclamping or guarding member were invented by C. F. Laganke, and the carbon-roll carried by the platen extension, the tension mechanismfor the tapes, andl the specific form of bill-slide or invoice-holder were invented by Joram Ziegler. To such featuresl make no claim. y

Along one side of the platen and outside of the adjacent track or guide isedetachably secured a slottedfgage-strip 41, equipped .with gage pins or projections 42, adjustablelalong IOO the strip andidesigned to coincide with and engage the file-openings of a sales-sheet 43,

disposed a billing-stri p 44, having detachable platen.

.equipped with a sliding work-holder or billconnection with one leaf, 45, of a hinge 46, the other leaf, 47, of which is fixed to a projecting portion 48 of the platen ata point beyond the rear end of the gage-strip 41. When attached as in use, the billing-strip is designed to swing down upon the gage-strip 41 with its upper edge substantially flush with the writing-surface. inasmuch as it clamps the edge of the salessheet and prevents the latter from becoming disengaged from the gage pins or projections 42, the upper ends of lhe latter being accommodated by one or more slots 49 in the billingstrip.

AOrdinarily the sales-sheet, secured in the manner stated, completely covers the Writingsurface of the platen and is designed to receive the transferred copy or record-entry of successive bills as they 'are made out ou the The billing strip 44 is therefore slide 50, having work-engaging devices-as', for instance, a pair of opstanding gage projections or studs 51. The work-engaging projections of the bill-slide are adjustable to accommodate them to the file or binding holes sition with respect to the sales-sheet as to cause the copy or record-entry to be made directly below or following the copy of the preceding bill. During the manipulation of the sales-sheet and bill to properly position them upon the platen the swinging sectionsof the main tracks or guides are sustained in an elevated position and are subsequently swung down upon the work-sheets to assist in their retention, the clamping action of the tracks being augmented by one or more spring-clips 52, carried by a track and extending'inwardly therefrom.

Obviously the reproduction of the bills upon the sales-sheet necessitates a transfer- 'ring element between the bill and sheet. For this purpose a loose carbon-sheet or one secured by the billing-strip might be employed. I have, however, shown the platen equipped with a carbon element or web 53, extending between carbon- carriers 54 and 55, mounted at the rear'end of the drop extension 14 and at the front end of the platen, respectively. As the carbon element becomes worn it is unwound from the delivering-roll upon the carrier 54 and is'wound upon the. front carrier 55 by the rotation ofthe latter through the medium of the thumb-wheel, suitable guide- rollers 57, 58, and 59 being mounted' at the opposite ends of the drop extension 14 and at the front end of the platen, respec- It will he noted that the location of It serves the purpose of a work-holder,A

drop extension permits the carbon element` to be moved with equal facility Whether the drop extension is up or,down,as in the latter position this roller will be located at the upper edge of the extension to guide'the web in an angular direction. Y

While the front guide-roller 59 and the front carbon-carrier 55 are located at the front end of the platen, theyare not directly carried thereby, but are sustained by the track-frame for movement therewith through the medium of suitable brackets, as shown.

Atthe side of the platen opposite the billing-strip 44 is located a laterally-adjustable tracks and secured at their front ends to card-A guides 64 and at their rear ends to slides 65. These tapes are designed to be adj usted laterally to present them'at the edges of worksheets of different widths, and the card-guidesY 64'are therefore slidably'secured to the framey bar 28, provided with a scale or series of graduations corresponding with the graduations upon a transverse tension-bar 66, slidably supporting the slides 65 and constantly urged rearwardly by springs 67, attached as shown. These strips or tapes are designed to guard theopposite edges of cards properly positioned upon the platen with the aid of the card-guide, and when folded bills employed in connection with some billing systems are to be written uponkthe right-hand tape is received within the folded edge or bight of the bill, with the other strip or tape disposed to guard the opposite edge thereof. employing a pair of stripsor tapes, as shown, the platen may be equipped with one onlyif it is simply desired to provide for the engagement of the fold or bightolj a bill, for instance.

The platen is further equipped with a transversely-disposed protecting-plate 68, having its opposite endsv slidably received within the grooves 69, formed in the inner faces of the tracks to permit the adjustment of the plate lengthwise of the platen. Whilethe protecting-plate is capable of being advanced over IIO Instead of the top edge of the sheet imposed upon the platen and is therefore equipped with a movable Work holding or guarding member 68, carried by the front ends of operating-levers 70, fulcrumed upon the protecting-plateand .having their rear ends 71 extending upwardly into the path of ,the front bar of the machinefraxne. When the machine is moved back from over the work, the frame-bar is designed to contact with the rear ends of the i operating-levers 70 for the purpose of swing- I urged in one direction by a spring 74 and having terminal lifting-arms 75, provided with small antifriction-rollers 76, which bear against the under sides ofthe tracks orguides. The power of the spring 74 is just sufficient to counterbalance the swinging frame comprising the tracks or guides and their connections, so that said frame may be easily manipulated by the operator. It is also desirable to protect the carbon-rolls by detachable guards 77, as shown.

Ordinarily the drop extension 14 is located in its inoperative position, as shown'in Fig. 3, and the front track-sections 26 are free to swing independently of the rear track-sections 25. AThat portion of the platen lying l the rear track-sections.

between the rear track-sections 25 therefore constitutes the normal platenextension, to a position over which the machine is moved, as shown in dotted lines, when it is -desired to elevate the swinging frame for the purpose of displacing the work element or elements from or replacing or adjusting the work within the normal printing area defined by that portion of the platen lying in advance of When the platen is used in this manner, the machine is stopped in its proper position by the machine-stops 39, secured at the front end of the drop extension. When, however, it is desired to write upon work-sheets of abnormal length,

the drop extension is raised to its horizontal position, where itis retained by the bracket 18,. and the front and rear sections ofthe vtracks or guides are rigidly connected in 'i alinement by the locking devices shown in Figs. 7 and 8. The raising of the Adrop extension withdraws the machine-stops 39 from the path of the machine and presents the auxiliary track-sections 24 in alinement with i the track-sections disposed above the platen.

The machine may now be moved back upon the extension beyond the rear end of the platen, where it will be arrested by the machine-stops 40. The swinging frame will then comprise the front and rear track-sections, movable in unison toward and away from the platen and swinging from an axis located at the rear end of the normal platen extension, which thus becomes a part of the printing area of the platen.

`In conclusion it may be stated that the.

platen extension 14 constitutes both a machine-support and a displaceable supplemental platen extension. Viewed merely as a machine-support it embraces a wide range of equivalents, lbecause the invention in one aspect thereof comprehends the broad idea of providing a machine-support of any character whatsoever located beyond the main body of theplaten and displaeeaole from its normal position either by actual removal or by a mere change of position. The expression displaceable machine-support used in the claims is employed in this broad sense. Considered in another aspect, however, the extension 14 constitutes a displaceable continuation or section of the main body ofA the platen, since while it is primarily designed to perform the function of a machine-supportit is nevertheless capable of being and under some conditions is designed to be utilized for the support of a work element or a portion of a work element, upon which a limited amount of matter may be printed by a machine located above the extension. In another aspect, therefore, the invention will be seen to comprehend a sectional platen, each section of which-is capable of displacement from its normal position whether by actual removal or by such movement as will displace it from that position which it normally assumes.

I make no claim to the subject-matter disclosed and claimed in the eopending application ofJohn A. Smith, Serial No. 67,346, the work-retaining devices being herein illustrated for the sole purpose of showing a fully equipped platen.

It is thought that from the foregoing the construction and mode of manipulation of the platen, as Well as the advantages accruing from its use, will be readily understood by those skilled in the art; but since theinvention in its broader aspect is of sufficient scope to include many constructions other than that described I wish to be distinctly linderstood as reserving the right to effect such changes, modifications, and variations of the illustrated structure as may fall properly within the scope of the protection prayed.
