ROBERT JOSEPH FISHER, OF ATHENS, TENNESSEE, ASSIGNOR TO THE FISHER TYPEW'RITER COMPANY, OF TENNESSEE.

TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 63 ,682, dated S p er 1 Application filed March 30,1898. Serial No. 675,738. (No model.)

To a/ZZ whom it may concern:

Be it known that 1, ROBERT JOSEPH FISHER, a citizen of the United States, residing at Athens, in the county of McMinn and State of Tennessee, have invented a new and useful Type-Writing Machine, of which the following is a specification.

My invention relates to type-writing ma chines of that class designed for bookwork, and particularly to a platen for use in connection With'a machine-support to maintain in a proper position a leaf or leaves to receive the impression of the printing characters; and the object in view is to provide a double platen adapted for supporting both of the exposed leaves of a book, to adapt the machine to be shifted from one to the other without varying the adjustment of the book or leaf supporting devices, and, furthermore, to provide a platen which is mounted upon the support for longitudinal or axial movement and is adapted to be arranged in operative position or to be moved out of the way to allow the adjustment of the book-leaves or to be moved from one side of a book to the other.

Further objects and advantages of this invention will appear in the following description and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a perspective view of a platen constructed in accordance with my invention applied in the operative position to a base adapted for supporting a book type-writing machine. Fig. 2 is a similar view showing the manner of arranging the platen leaves or members in operative relation with the book -leaves. Fig. 3 is a similar view showing a platen consisting of a single leaf or member. Fig. 4 is an inverted plan view of the base to show suitable means for adjusting the platen-supports. Fig. 5 is a longitudinal section of the base. Figs. 6 and 7 are detail sectional views on the planes indicated by the lines 6 6 and 7 7 of Fig. 4. Fig. 8 is a detail view of the platen to show the means for pivotally mounting the same.

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

The base 89, which may be constructed in the form of a horizontal table top and may, as illustrated, be provided with suitable supporting -legs, is longitudinally slotted, as shown at 90, for the reception of strips 91, forming platen supports, the interval. between the strips being such as to receive a book 92, resting upon the base, and the strips being designed to bear the weight of tracks 1 of atype-writing machine, such as that illustrated in either of' my former patents, No. 569,491, dated October 13, 1896; Nos. 569,625, 569,626, and 569,627, dated October 20, 1896; No. 572,535, dated December 8, 1896, and No. 573,868, dated December 29, 1896.

The means illustrated in the drawings for varying the vertical adjustment of the supporting-strips include segment-gears 93, connected in pairs by spindles 94, which are arranged longitudinally of the base, racks 96, depending from the strips contiguous to their extremities and engaged by said segmentgears, and worms 97, meshing with wormgears 98 on said spindles and carried by a worm-shaft 99, which is mounted transversely of the base and extends beyond the front edge thereof within reach of the operator to receive an operating-crank 100, all as clearly shown, described, and claimed in a pending application of Robert J. Fisher and C. L. Laganke, Serial No. 675,729, filed of even date herewith.

Arranged upon the supports 91 or any equivalents thereof forming a part of a suitable machine-support is a platen 101, which in the construction illustrated spans the interval between the strips and rests at its front and rear-edges, respectively, thereon,whereby a leaf which is to receive the impression is brought to and arranged upon-the upper surface of the platen and is there held by the superposed tracks 1. In the construction illustrated in Figs. 1 and 2 the platen is double or of a double-leaf form, whereby it is of sufficient area to cover both sides of a book, and thus support both of the exposed leaves when the book is opened. Upon a transverse line (or a line transverse to the line of writing) between the parts or different platen leaves or members is formed a slot 102, up-

wardly through which may be extended a plurality of book-leaves to arrange them, respectively, upon the said platen leaves or members. By this arrangement it is possible to write on either of the exposed pages of a book without changing the adjustment of the supporting devices or the position of the. book, both of the exposed pages being arranged in a common plane upon the upper surface of a continuous platen, which is coextensive with the combined surfaces of the exposed leaves and is supported, as above indicated, by the base or the vertically-ad j ustable supports 91, which may be used in connection with the base. In the construction illustrated this platen is pivotally or hingedly mounted, preferably at its rear edge, upon one of the supporting-strips, as by means of hinge eyes or clips 103, fitted upon a hinge rod or pin IOi, secured to said strip, whereby the platen is permanently attached to the base and is adapted to swing upward to expose a book when it is desiredto turn a leaf thereof. A ter opening the book two or more leaves may be raised, as indicated in Fig. 2, and inserted edgewise through the transverse slot of the platen between the leaves or members thereof, and thereby extended to the upper surface of the platen for subsequent outward folding to lie in a horizontal position, as indicated in Fig. 1.

In the construction illustrated in Fig. 3 the platen 101"" is coextensive with only one leaf of a book, but is pivotally mounted at one edge upon the contiguous support or other suitable portion of the base by means of hinge-eyes 103 fitted upon a hinge rod or pin 104:. This modified construction of platen thus corresponds approximately with one leaf or member of the double platen illustrated in Figs. 1 and 2.

In both of the illustrated forms of my leafsupporting device, however, the platen is not only mounted for swinging movement upon the base, but is capable of axial movement parallel with the lines of writing, and in order that this movement may be accomplished the hinge rod or pin is extended beyond the hinge-eyes to allow an adjustment of greater or less extent in order that the particular position of the book upon the base may be accommodated by,the platen without necessitating accuracy in the placement of the book. In other words, if the book should be so arranged upon the base that the binding-crease is not accurately alined with the slot in the platen (illustrated in Figs. 1 and 2) or the edge of the leaf (illustrated in Fig. 3) the necessary longitudinal adjustment of the platen may be accomplished to produce such alinement, and thereby avoid diificultyin disposing the parts in their proper relative positions and also avoid the risk of tearing or otherwise injuring the leaves of the book in the course of such adjustment. Furthermore, from the above description it will be seen that, particularly with relation to the double platen, any tendency upon the part of a leaf at the thicker side of the book to bulge and thus interfere with the proper manipulation of the machine will be prevented by the weight of the platen, and obviously of the superposed machine, whereby the parts will be properly held in operative positions. v

lhat portion of the construction described and shown in this application which relates to the adjustable machine-supporting strips and the platen hinged to one of the strips for vertical swinging movement to expose a subjacent book forms no part of my present sole invention, but is claimed in a copending joint application of R. J. Fisher and C. F. Laganke, Serial No. 675,729, filed of even date herewith.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invent-ion, what I claim is 1. A platen for book type-writing machines, having leaves or members connected forsimultaneous movement and arranged in a common plane to respectively support book-leaves, and having an intermediate space or passage through which book-leaves may extend to the upper surface of the platen leaves or members, substantially as specified.

2. A platen for type-writing machines, having pivotal leaves or members connected for simultaneous swinging movement, and arranged in a common plane to respectively support book-leaves, and having an intermediate space through which book-leaves may extend to the upper surface of the platen leaves or members, substantially as specified.

3. A platen for book type-writin g machines, consisting of a continuous plate provided at an intermediate point with a transverse slot for the reception of a plurality of book-leaves for extension in opposite directions, and providing writing-supports on both sides of said slot, substantially as specified.
