FREDERIO W. HILLARD, OF TOTTENVILLE, NEW YORK, ASSIGNOR TO THE ELLIOTT dz HATCH BOOK TYPEWRITER COMPANY, OF NEW YORK, N. Y.,

A OORPORATION'OF NEW YORK.

BOOK-TYPE-WRITER TABLE.

SPECIFICATION forming part of Letters Patent No. 726,922, dated May 5, 1903.

, Application filed August 31, 1901. Serial No. 74,016. (No model.)

To aZZ whom it may concern.-

Be it known that I, FREDERIC W. HILLARD, a citizen of the United States of America, and a residentpf Tottenville, in the county of Richmond, city and State of New York, have invented certain new and useful Improvements in Book-Type-Writer Tables, of which the following is a specification.

This invention relates to book-type-writer [0 tables of the gen eral principle disclosed in my application, Serial No. 27,040, filed August 16, 1900, in which two book-supporting leaves or book-rests are employed, one for each cover of a book, and which are relatively movable one to the other, the parts being so disposed as that ample room is provided in the space under the book-rests for the legs of the operator.

The objects of the invention are to provide a book-typewriter table in whichthe said book-rests are mounted so as to move independently one of the other and to self-adjust themselves when loose, according to the thickness of the book, after which they maybe fixed stationary, so that writing upon the book may take place.

My invention consists of certain features of construction and'combi-nations of parts, to be hereinafter particularly described and then claimed.

In the accompanying drawings, Figure l is a front elevation of a book-type-writer table embodying the present invention, the writing mechanism being indicated in dotted lines. I

Fig. 3 is Fig. 2 is a plan view of the same.

an end view thereof, and Figs. 4, 5, and 6 are detail views showing the means for adj usting and setting the book-rests in position.

Referring to the drawings, A indicates the 40 table; B, the writing mechanism; B, the baseframe therefor, and O the platen. The platen and the base-frame are pivoted on a shaft D, which is mounted on small wheeled guidetrucks cl, the wheels of which travel upon the 5 top of the table, and the frames of said trucks being each provided with an undercut groove which receives a correspondingly-sectioned guide-rail A, which is fixed to the rear part of the top of the table and extends longitudinally thereof, so that the platen and all the writing mechanism may moved lengthwise of' the entire length of the table. A longitudinal guide-rail A is fixed to the front of the top of the table in position parallel with the guide-rail A, and the platen has at its outer end a guide-roller O, which runs on the said rail A The object of this construction is to enable the writing mechanism to be movedsay to the right-hand end of table'so as to clear the book-rests E E, which move in an opening in the top of'the table.

. Book-rests E E aresupported in parallel position at a suitable distance apart, preferably by means of upright slides F F, which are secured to the rear ends of the book-rests EE and are braced by angle-irons or brackets e e. The slides F F are guided in Vertical parallel gnideways atfon the inner surface .of the back of the table, so as not to interfere in the space under the book-rests with the legs of the operator.- Each of the slides and the book-rest supported thereby is; subjected .to .a lifting action'bylmeans, preferably, of a helical tension spring G, hung on a stud g, projecting through a slot f from the back of. the table, and the lower end of which spring carries a screw-threaded stem G, that passes loosely through a perforated lug g at the lower end of the slide, and is adjusted longitudinally therein, so as 80 to create more or less tension on the spring, by means of a thumbnut 9 that works against the under side of said lug. When the book-rests are'free to give todownw-ard pressure, a book placed in writing position thereon will lower them, and when the platen is lowered so that its front guide-roller comes in contact with the front rail A thebook-rest E, over which the platen islowered in the position of parts shown in Fig. 1, will be depressed to the proper level'or plane, while the cover and leaves of the other half of the book exert a leverage action on the other. book-rest E and cause it to seek the proper level or plane. In these or any other positions in which the book and platen will cause the book-rests to be automatically moved to the proper level or plane the book-rests are ordinarily fixed rigidly in position for permitting the proper functioning of the writing mechanism. Each slide F is therefore provided with a locking device (shown in Figs. 4, 5, and 6 in detail) constructed, preferably, as follows: To the table, at each side of the space under the book-rests, is pivoted at h a lever H, the inner rear end of which is connected by a link it with an ear 7&2 on the under side of the book-rest and the forward end of which is provided with a sleeve i, through which is guided a spring-pressed locking-pin t", that is provided at its outer end with a button I, so that the locking-pin may be retracted to overcome the spring action and to withdraw it from any one of a series of holes j, formed in a plate J, fixed to the table. In permitting the book-rests to self-adj ust themselves according to the thickness of the superposed parts of the book to be written in the pins t" are retracted from the holes j receiving them, and when the required set of the book-rest is obtained the pins are released and permitted to engage with the nearest hole.

If a leaf above the book-rest E is to be written upon, the platen and writing mechanism are shifted thereover, while if a leaf above the book-rest E is to be written upon they are shifted thereover, and in either case and when the platen and writing mechanism are to be moved entirely clear of the book at the right-hand end of the table the said parts are guided on the longitudinal top rails, which extend from one end to the other of the table.

It is evident thatcertain changes are within the scope and spirit of the invention-as, for instance, the book-rests and manner of supporting and operating them may be differently constructed in a case where the writing mechanism travels on rails in front of and behind the same.

What I claim as new is- 1. In a book-type-writer table, the combination of two independent slides, suitable actuating-springs suspended from their upper ends and acting, at their lower ends, on the slides, and book-rests supported by the slides, substantially as described.

2. In a book-type-writer table, the combination, with a book-rest, of a stationary guiderail extending along the rear of the table, a truck guided on the said rail, and a platen for the writing mechanism, guided on said rail, and pivoted to said truck, substantially as described.

3. In a book-type-writer table having vertical guides in the rear thereof, the combination of two independent slides, moving in the guides, book-rests projecting forwardly from and supported by the slides, springs hung at their upper end from the table and having their lower ends attached to the slides, and an operating-lever provided with locking devices for fixing the position of the book-rest, substantially as described.

4. In a book-type-writer table having vertical guides in the rear thereof, the combination of two independent slotted slides moving in the guides, book-rests projecting forwardly from and supported by the guides, studs projecting from the table through the slots in the slide, springs fastened at their upper ends to the studs and having their lower ends attached to the slides, and levers, one attached to each of the slides, and provided with looking devices for fixing the position of the bookrest, substantially as described.

5. The combination with a book-type-writer table, comprising two independently vertically self-adjustable book-rests and guide rails supported independently of the bookrests in the front and rear thereof, of a writing-machine comprising a platen and writing mechanism pivoted to one of said rails and resting on the other, the platen and writing mechanism being movable on the two guiderails, substantially as described.

6. The combination with a book-type-writer table, comprising independent book-rests, and having stationary guide-rails arranged in front of and behind the rests of trucks movable on the rear rail, ashaft mounted on the trucks, and a platen and writing mechanism pivoted on the shaft and adapted to rest on the front rail, substantially as described.

7. The combination with a guiderail, of trucks movable thereon, a shaft carried by the trucks, and a platen and writing mechanism pivoted on the shaft, substantially as described.
