1 lApplicationfiled June 13, 1898. Serial No. 683,326. (No model.)

To all whom it may-concern.-

Be it known that'I, I-IIRAM J QSEPH HALLE, a, citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful Type-Writing-Machine Support, of which the following is a specification.

My invention relates to type-writing machines, and particularly to a support for book type-Writing machines, and has for its object,

primarily, to'provide such a construction of support that the machine may be positioned wholly outside of or beyond the possible printing or operative field or area Without raising or otherwise moving the machine except parallel with the printing-surface, as in the operation, for example, of line-spacing, such abnormal positioning ofthe machine being designed to expose the printing area, and thereby facilitate the adjustment of the impression-receiving object, such as a book or sheet, or to simplify the operation of turning the leaves of 'a book constituting the impression-receivin g object.

' A further object, of my invention is to provide machine supporting and guiding members respectively positioned outside of or be yondand spanning the printing field or area, or that space within which the printing is accomplished,said supportingand guiding members being of analogous construction and being so related that the machine by a continnation of its line-spacing movement may be caused to pass from one member to the other.

' A further object of my invention is to provide, inconnection with or constituting a machine-support, rails, tracks, orguides of sectional construction having stationary or permanent and movable or displace'able elements, of which the latter span the printing field or area of the type-writing machine,

while the former are locatedoutside of or bethe same, showing the base in section and indicatin g in full and dotted lines the operative and displaced positions of the type-Writing.

machine upon the rails, the movable member of the support, including the platen and the movable rail elements, being shown in dotted lines in their elevated or displaced position. Fig. 2 is a detail view of one end of amovable rail element inverted to show the retainingportion of one of the rails or tracks having connected elements. Fig. 5 is a detail sectional view of the joint between the elements of the rail or track. Fig. 6,.is a plan view of the same. Fig. .7 is a detail view in perspective of transversely-connected rail elements hinged for swinging'movement. Fig. 8 is a detail section of the joint and clamp. Fig. 9 is a perspective view of a modified construc: tion of the typewriting-machinesupport embodying my invention, wherein the platen is connected with an extensionor temporary machine-rest by ahinge-joint, both platen and extension or rest being detachable from the base; Fig. 10 is a' side view of the same, showing the base in section. in perspective of the platen and extension or rest detached. Fig 12 .is a perspective view showing another modification of my invention, wherein the platen extension or rest, which is outside of or beyond the printing area or field, is coextensive with the adj ustment of the platen and is permanently fixed to the rear supporting-strip, a double platen or onecapable of upholding two book-leaves being shown in this connection. Fig. 13 is a sectional view of the-same, showing in full and dotted lines the operative and inoperative positionsof a type-writing machine mounted Fig. 11 is a detail view" loo movable platen-leaves. Fig. 15 is a vertical sectional view of the same.

Fig. 16 is a I 7 detail View in perspective of another "modi f fied construction and arrangement of supporting means embodying my invention, wherein the movable rail elements have a horizontal swinging movement in contradistinction to the Vertical swinging movement of the cor-responding parts in the foregoing figures. Fig. 17 is a detail plan view of a portion of one of the rails. Fig. 18 is 'a detail sectional view of the joint between the elements of the rail shown in Fig. 17.

Similar reference characters indicate corresponding parts in all the figures of the drawings.

The base 1, Figs. 1, 2, 3, 9, and 10, which may be constructed in the form of a horizontal table-top and may, as illustrated, be provided with suitable supporting-legs, carries front and rear, preferably adjustable, supporting strips 2, the interval between the strips being such as to receive a book positioned upon the base or a book-supporting member thereof. When adjustable, the strips are provided with operating mechanism, consisting in the construction illustrated of segment-gears 3, connected in pairs by spindles. 4, which are arranged longitudinally of the base racks, 5 depending from the strips and engaged by the-segment gears, and worms 6,

meshing with worm-gears 7 on said spindles, and carried by a worm-shaft 8, provided beyond the front edge of the base and'within; reach of theoperator with an operating-crank 9. The means for vertically adjusting the strips form-no part of my present invention.

The strips in the construction illustrated (see Figs. 1 to 4 and 10) carry a platen 10,which spans the printing field or area or the interval between the strips and is coextensive with one or more leaves of a book located between the strips or with a sheet orother impression receiving surface upon which type-impressions are to be made by means of a type-writing machine mounted to traverse the printing area, and a platen extension or temporary machine-rest 11, which is located beyond or are adjustably mounted, as hereinbefore described, whereby the adjustment of the strip causes the corresponding adjustment of the platen extension or rest. The platen is movably mounted with relation to the platen extension or rest and'may be hinged upon the rear strip, as indicated in thedrawings, Figs. 1 and 2, by means of hinge eyes or clips 13 and 14, fitted upon a hinge rod-or pin 15,

a type-writing machine in traversing its surface, and preferablythe book-leaf or. sheet which is receiving the impression is held in a flat condition upon the surface of the platen by means of rails 17, constructed to carry the frameof the. type-writing machine,- and one or both being of sectional construction or con sisting of elements of which a main or movable element is supported by and spans the surface of the platen, while a rail extension or stationary element 18 is supported by the platen extension or rest 11 or other analo gons means for maintaining the stationary or auxiliary rail element ,in position to receive the type-writing machine when outside the printing area. Also these rail elements may be hingedly connected, as shown in Figs. 4 to '7 and 12 to 18, the length of the auxiliary or extension rail elements in either form being sufficient to support a .type writing machine when the latter is disposed beyond the print ing field and is at rest. Obviously the length of the main rail elements depends upon the width of the printing field and may be varied to be used in connection therewith.

Various means may be adopted to maintain the platen and the extension or'rest in the de-.

sired relative positions and in the required positions with relation to the supporting of the other, whereby the adjustment of the platen parallel with the hinge-rod causes the corresponding adjustment of the extension or rest, the latter being provided with means, such as depending earstltl, (forming parts of the above-described brackets 12,) which bear against the rear side. of the rear strip 2 to maintain the rest in a horizontal position or in a common plane with the platen when the latter is in its operative position. In the construction illustrated the ears l9 consist of the 'downtu rned portions of the an gle-brackets 12, 'hereinbefore mentioned, and in this construction (shown in Figs. 1 and 2) said brackets may be secured to the under side of the rest In this particular of the attachment of the brackets to the underside of the rest the construction illustrated in Figs. 1 and 2 difiers I00 to suit the functions of the machine which is j rest l andll are connected by interlocking eyes 13 and 14 and an engaging hingerod 15, the latter being separateffrom the strip 2*, and hence providing for the arrangement of the platen at any desired point or the entire removal thereof with the rest from the base, as indicated in Fig. 11.

In this construction, (shown in Figs. 9 and 10,) however, I have found it desirable (to prevent rearward displacement of the platen) to provide removable with the platen from the supportting-strips. Again, in Figs.y12 and 'l3 the platen 10 which is supported by the front and rear strips 2*, is-supplemented to form a stationary or temporary support for the type writing machine by a stationary. rest 11,

which is permanently secured to the rear strip 2 by brackets-12 In this construction the rest 11 which is arranged in a common plane with the platen may be made coequal in length with said strip, and hence withthe path of the platen, which by means of eyes 13 is mounted for adjustment upon a hingerofd l5 carried by said rear strip 2". Moreover, in the construction illustrated in Figs. 14- and 15 the base 1 is constructed with the front and rear supporting-strips 2 flush therewith strips,and hence requiring n 0 further detailed and stationary, and the book is adapted to be supported below the plane thereof by a vertically-adj ustable platform or book-support 21, coextensive with the printing field or area and provided with adjusting devices'analogous to those hereinbefore described as designed for securing the adjustment of the supportingdescription. In this form of the apparatus a plurality of platen-leaves 10 may be hinged to the rear strip 2 and flush with the upper surface thereof, and hence the table-top or base, and the latter is provided with an extension 11,formin'g a temporarymachine supplane of the platen 10.

port or rest which is adapted to perform the functions of the platen extensions or rests 11, 11, and 11", as hereinbefore described in connection with other forms of my invention, said rest 11 also being flush or in acommon have shown a base 1, frontand rear supporting-strips 2 and aplaten 10 ,which, however, incontradistinction to those forms of my invention which are described in connection with the foregoing figures, is hinged at its side edge to fold laterally instead of folding from the operator, for a reason whichwill be understood as the nature of my invention is more fully disclosed. In this form of my invention the temporary machine support or rest ll is also permanently secured in the In connection with the construction. illusadjustment of the main rail elements.

trated in Figs. 1. and 2 it willbe seen that I have shown tracks arrangedin parallelism upon bothleaves or members of the platen and consisting of rails, of which those elements which'are arranged upon the platen 1O may be disposed, as shown, to allow a bookleaf or other impression-sheet to be arranged thereunder or between the same and-the upper surface of the platen to receive the impression ofthe printing characters. These rail elements, while arranged in parallelism in order to allow the machine traversing the same to be pushed from those upon the platen to those upon the temporary machine support or rest without raising or lowering the machine or otherwise moving it out of its straight path, need not be in alinement, and for reasons hereinafter made clear the rail elements which are arranged upon the platen maybe movable or adjustable laterally with relation to each other to vary the interval therebetween to suit lines of writing (at right angles to which said rails'are arranged) of difierent iliary rail elements 17 and 18 are shown inparallelism, but out of alinement, the interval between. the auxiliary rail elements being such as to correspond with the Widest or most remote setting of the main rail elements, and

hence being designed to support. the machine.

when pushed rearwardly thereon at any relative adjustment of the main rail elements 17.

auxiliary rail elements at their rear ends are provided with stops 22 to limit the rearward movement o f'a machine traversing the same to prevent displacement, and both the main and auxiliary rail elements may be provided with depending pins 29 and 24 to engage sockets 25 and26 formed in the machine-rest. It will be understood, however, that other means The IIO

ments in the desired positions upon the platen and .rest, or with sufficiently heavy rails attaching devices may be dispensed with env tirely. ,plane with the platen 10. ,Also in Fig. 16 I a The machine-support which forms the subject-matter of this invention is designed for supporting and guiding typewriting machines of different constructions, which may. be required to occupy positions alternately, within and outside of or beyond the printing area for the reasons fully explained; but said support. is adapted particularly for use in connection with type-writingmachineS'of the type and general construction shown and de-- scribed in the patents of R. J. Fisher, as follows: No. 569,626, dated October20, 1896; No. 509,927, dated October 20,1896; No. 569,491,

' 580,855, dated April 20, 1897, and No. 569,625,

dated October 20, 1896, and in the copending applications of the same,-as follows: Serial No. 660,272, filed November 30, 1897, and

Serial No; 671,147, filed February 21, 1898.

to the lines of writing for line-spacing purposes. To receive and fit the tracks, the machine-frame of saidpatents and applications of Fisher are provided at the bottom with front and rear alined seats; but to allow variation of the interval between the tracks a plurality of seats spaced laterally are used. Therefore when, as herein described,the front or main track elements are spaced at one interval, while the rear or auxiliary track elements are spaced at a different interval, and hence are alinedwith other seats of the machine-frame from those occupied by the main track elements, the movement of the machine from the main to the auxiliary track elements may be accomplished with the same facility as though the track elements of the two sup port members were in alinement. The only difference is that when the frame is pushed back different track-seats engage the auxiliary track elements from those which have been in engagement with the main track elements instead of the same track-seats. Thus, provided the track elements of both support members are in parallelism, the operation is the same whether the alinement of the cooperating elements is preserved or not.

In the construction illustrated in Figs. 9 to 11 a corresponding separate and non-alined arrangement of rail elements 17 and 18 is disclosed, the same being provided with corresponding means of attachment to the platen and rest, said means being such as to provide for the displacement or detachment of the rail elements and consisting of pins on the rail elements fitted in openings or sockets 25 and 26 in the platen and rest. The detachable form of platen illustrated .in 'said Figs.

9 to 11 is desirable in that it is adapted to be used in connection with other than the special form of supporting means or strips disclosed in these figures, and,in fact,constitutes the simplest form of type-writing-machine Jsupport having main and auxiliary (or movscription that the forms of rails or tracks illustrated in'Figs. 1, 2, 9, and 10 are adapted to be arranged in alinement when the space required between themainrail elements is equal to that which is provided between the auxiliary rail elements. Therefore in opera-.

tion when it is desired to change thebook by turning one or more leaves or otherwise to arrange or secure the required surface or ob ect to receive the impression of the printing characters the type-writing machine, which is indicated in dotted lines in Fig. 2, should be shifted beyond the printing area to a'position upon the stationary or auxiliary support member, as upon the auxiliary rail elements, where it is supported by the rest. The front ends of the rails or the movable elements thereof may then be elevated to adjust the sheet or page upon the'platen 10,0r bothrails and "platen may be elevated to allow the change of to dispose it beyond or outside of the printing area, whereupon those elements of the rails which span the printing area and the platen, or either of them, and which serve as the means of support for the machine when the latter is in operation may be moved or dis alined. On the other hand, I have found it desirable under certain circumstances to have the rail elements constructed for permanent alinement, whereby the adjustment of the main or operative elements thereof is accompanied by a correspondingadjustment of the auxiliary, or, as I have hereinbefore termed this feature, stationary elements. For instance, in Figs. 4 to 6, inclusive, the main and auxiliaryrail elements 17 and 18 are hingedly connected by a pivot-pin 27, the auxiliary or stationary rail element having a joint stiffening or strengthening tongue 28,"which is preferably flush with the under side of said rail element and is adapted'to be countersunk by fitting normally in a cavity 29 in the under side of the member 17 This hinge connection between the rail elements is shown also in Figs. 14to 18, inclusive; but in Figs. 16 to 18 the elements 17 d and 18 are connected pivotally by a vertical pin 29 whereby the front or movable rail elementsare adapted to swing laterally-in ahorizontal plane, as indicated by the dotted lines in Figs. 16 and 17, to expose the printing area or field.- Also in Figs. 7 and 8 I have shown, in connec- {tion with the hinged movable rail'elements 17 a transverse connecting-bar 30, having notches 31 to receive pins 32, depending from] ments at their points of intersection.

621,660 i a f pins preferably consistingof set-screws having heads 33 and being threaded into sockets in the under sides of the i rail elements to clamp the connecting-bar and the rail ele- It will be seen that the desired notches 31 of the conpreparatory to again lowering the rail elenecting-bar maybe engaged with the pins 32 to hold the rail elements at the desired relative adjustment at their front ends and at the same time enable the operator to lift both movable rail elements in one operation, as-by the thumb and forefinger of one hand, to

leave the other hand free to move the platen or to properly position the leaf or impressionsheet upon the upper surface of the platen ments. When the connecting-bar 3O isomployed, the movable rail elements should extend slightly beyond the front edge of, the

platen, whereby the bar occupies a position in the plane of the platen.

' In the'construction illustrated inoFig. 16 the movable rail elements 17 may be held in their normal positions by means of spring or yieldingstops 34 or the equivalents thereof,

suit the lateral swinging movementof the platen 10.

Finally, it will be seen that the essential feature of my invention resides in the construction of a type-writing-machine support having two members, of which one is permanently located outside of or beyond the printing field or area, while the other is normally located to span the printing field or area, but is movable into and out of said printing field or area to provide for the arrangement of the leaf or sheet which is to receive the impression, the first-named member being adapted to receive and uphold the type-writing machine temporarily when the latter is at rest,

while the last-named or main support member is designed to normally uphold the ma- The term support members as I have used it in thisdescription applies to the means for upholding and guiding a type-writingmachine while in operation and at rest or while traversing the printing area or field and when located outside of orbeyond said area or field; and said term in the sense in which it is used herein applies broadly to either the platen and temporary machine-rest or the tracks or trails (with their stationary and movable elements) or to both the platen and rest and the tracks or rails, the stationary supportmemher, being that member which is located permanently outside of or beyond the printing area and Whether consisting of the rest or the auxiliary rail elements, or both, and the movable support member being" that member which is located within and spans the printing area or field (the same being displaceable to expose said area or field for the adjustment of the impression-receiving surface or object) and whether consisting of the platen or the main rail elements, or both. Furthermore, it will be seen that the platen is not an indispensable element of the mechanism described,,for it has been demonstrated that with suitable supporting devices, such as rails, spanning the printing field or area tobe traversed by the, machine printing may be {done directly upon the surface of a book-leaf which is unsupported throughout. its area by a platen; but it is obvious that the result undersuch conditions is not as satisfactory as when a firm backing is employed for the leaf or sheet which is receiving the impression, owing to the yielding quality of the bookleaves, particularly when they are .in bulk or when there is a considerable depth of leaves.

In the sameway'it will be understood from the foregoing'description that the rails, as shown and described, are not-wholly indispensable, provided some means are employed to guide the type-writing machine in travels-- in g the printing field or area'and provided that member which serves to support and guide the machine while traversing the printing field or area is movable whenrelieved of the machine to expose the printing field or area,

said machine passing to a point beyond the printing field or area to release said movable supporting member; but the result attained by the use of the rails, and particularly when those rails are loose or are movable independently of the supporting-surface, such as the platen described in connection with my apparatus, is far more satisfactory than when 1 those members are omitted, for the reason I,

that the rail elements which span the printing field or area serve to maintain the leaf or impression-sheet in its proper position upon the supporting-surface or platen, and thus insure. a sharp impression of the type-faces. Moreover, in the, drawings Ihave shown (see Figs. 1, 9, and 11) a platen which is adapted to support only one leaf or sheet and which the featuresof construction which'have been shown and described are equally applicable to a double platen or one which is capable of supporting the opposite pages-of a book simultaneously. (See Figs. 12 a and 16.) It will be understood, moreover, that various other changes in the form, proportion, and minor details of construction than have been specificallyshown and described may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. Having described my invention, what I claim is-' V 1, A support for type-Writing machines, having members arranged respectively ou tside of and within the printing area, and
