SUPPORTING-TABLE AND ATTACHMENT FOR TYPE-WRITERS.

SFECIFICATION forming part of Letters Patent No. 759,820, dated May 10, 1904.

Application filed November 10, 1903. Serial No. 180,539. (No model.)

for 'Iype-W'riters, of which the following is a specification.

' The purpose of my invention is to provide a supporting-table for typewriting machines adapted to write upon flat surfaces in which the machine is supported upon tracks or ways at a fixed distance above the writing-surface; and it includes means for supporting a movable platen at the proper height to receive the impressions of the type and also means for holding a book with the page to be printed upon at the proper height to receive the impressions of the type and for clamping the pages of the book lirmly together, so that the book-pages may be written upon without the use of a platen arranged between the pages.

In the accompanying drawings, Figure 1 is a top plan view of the writing-machine table with the cover removed, showing a book arranged. upon the adjustable book-support beneath the clamping-frame and the guideways for the writing-machine. Fig.2 is a central transverse section through the upper portion of the supporting frame or table on the line 2 2 of Fig. 1, the adjustable book-support and clamping-frame being shown in side View. Fig. 3 is a top perspective view of the clamping-frame. Fig. 4 is a top plan view of the supporting-table having the machine-guideways attached with the cover carrying the platen-guideways arranged upon the table and the platen-carriage and platen upon the guideways, and Fig. 5 is a section on the line 5 5 of Fig. 4.

Referring to Figs. 1, 2, and 3 of the drawing-s, A indicates the body of the frame or casing which supports the writing-machine and the various devices for holding a book or sheet of paper at the proper height relatively to the machine to receive the impressions of the type. This frame or casing, as shown in Figs. 1 and 2, has vertical front and rear walls 1 and 2, respectively, parallel with one another, and parallel end walls 3 and 4, the the upper portion of the casing being oblong and rectangular in top plan view, as shown. A pair of parallel guideways 5 and 6 are arranged transversely of the supporting table or casing at a fixed height above the upper edges of its walls, these guideways, as shown, being supported by standards 7, which are secured to the rear side of the supporting frame or casing. Within the interior of the casing is arranged. a rectangular book-support 8, fitting closely against the walls of the casing and having a flat upper surface. This book-support may be adjusted vertically by any suitable means. In the drawings the book-support is secured at its center to a vertical screw 9, upon which is journaled awormwheel 10. The worm-wheel is arranged within an opening .11 in a supporting-bar 12, which latter is secured at its ends to the walls of the casing and supports the worm-wheel, the latter in turn supporting the screw and the booksupport. The book-support may be raised and lowered by means of a hand-wheel 13 upon a worm-shaft 14, having a worm 15,which engages the teeth on the worm-wheel.

As the writing-machine guideways are held rigidly in a horizontal position, it is necessary in order to elfect proper printing to maintain the page of the book B, which is to be written upon, at a fixed distance below the level of the machine-guideways. For this purpose I provide a flat clamping-frame 0, having a rectangular central opening 16 of suflicient length and width to expose the area upon the book-leaf where it is desired to print. The side bars 17 and cross-bars 18 rest upon the sides and ends of the page, respectively, when in position. Gage-pins or projections 19 are secured to the corners of the clampingplate and project vertically downward from itsunder side. The lower ends of these pins, as'shown in Fig. 2, are adapted to rest upon the upper edges of the walls of the casing, and these gages support the clamping-plate at the proper height relatively to the machine-guideways, so that when the book is forced upward by the boolosupport against the under side of the clamping-plate the page of the book will be firmly held at exactly the proper distance from the impression-point of the writing-machine. In order to hold the clamping-plate firmly against the book, latches 20 are provided at each end of the clamping-plate, and these latches engage hasps 21, secured to the front and rear walls of the casing. The upward pressure of the book-support compresses the leaves of the book, so that they form a sufficiently firm printing-bed, and it is unnecessary to use a platen beneath the page which is being written upon. This device for readily setting and holding the page of a book at a fixed distance from the writing-machine is designed particularly for use in connection with a machine such as shown in my application, Serial No. 148,611, filed March 19, 1903, in which the writing-machine is movable toward and from the operator, and a platen is also movable toward and from the operator. In writing upon heavy books the machine is thus adjustable for line-spacing; but in writing upon bill-heads or other light detached papers it is of advantage to allow the machine to remain stationary and move the platen for line-spacing, as this leaves the writing-machine always at the same distance from the operator and the work becomes less irksome. In order to provide a supporting-table suitable for both purposes, the clamping-frame referred to is made detachable from the supporting-table and a cover D (shown in Figs. 4 and 5) is provided, which cover when in position rests upon the upper edges of the casing and is secured in position by dowel-pins 22, secured to the cover and entering suitable openings in the upper edges of the casing. Upon this cover are arranged platen- guideways 23 and 24, extending parallel with one another and transversely of the cover. Upon these guideways is arranged a platen -car riage 25, consisting of a light metal frame, and a platen 26 rests upon the platen-car- .riage. The platen-carriage is provided with a rack-bar 27, and suitable mechanism 28, arranged upon the cover I), is provided forspacing the platen rearwardly along the platen guide rails for line spacing. The platen carriage, removable platen 26, and spacing mechanism form the subject of my pending application, Serial No. 17 5,77 3, and need not here be particularly described. The upper surface of the printing-bed 26 of the platen is when in position at the same height or distance above the upper edges of the easing as the page of a book when the latter is pressed against the under side of the clamping-plate C in Fig. 2, so that it is at'the exact height for receiving the impressions of the type from the machine, which travels on the fixed machine-guideways 5 and 6. The platencarriage may be omitted, and a platen provided with a rack may be spaced along the platen-guideways, in which event it will of course be necessary to raise the platen to the desired height by increasing the height of the rails or the height of the cover above the edges of the casing.

It will be seen from the foregoing description that with my improvements the supporting-table maybe arranged for bookwork or for lighter work admitting of platen-spacing in a few moments.

Having described -my invention, what I claim, and desire to secure by Letters Patent, 1s-
