UNITED sTATEs PATENT OEEIOE.
JOHN W. JOHNSON. OF BROOKWAYVILLE, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO JOHN ADAMS, OF BROCKWAYVILLE, PENNSYLVANIA.
Specification of Letters Patent.
Patented. Dee. 18, 1906.
To all whom it mfay concern:
Be it known that I, JOHN W. JOHNSON, a citizen of the United States, residing at Brockwayville, in the county of Jefferson and State of Pennsylvania, have invented new and useful Improvements in Book-Oarriers, of which the following is a specification.
This invention is a book-carrier, and has for its obj ect to provide a simple and efficient movable support for a ledger Or other book, so that the bookkeeper can easily shift the book back and forth to bring it in front of him in order to have access to a different portion of the book without changing his position.
In the accompanying drawings, Figure 1 is an edge View of the invention. Fig. 2 is a central longitudinal section. Fig. 3 is a plan view. Fig. 4 is an inverted plan View of the book-carriage, and Fig. 5 is a section on the line 5 5 of Fig. 3. v
Referring specifically to the drawings, 10 denotes a base-plate having on top a track 11. At the ends of the base-plate are cleats 12, which serve as stops to revent the carriage from sliding off the trac i endWise. rIhe carriage is a flat plate 13, havin on top cross-strips 14 for holdin the book 1n proper position thereon. In te bottom of the plate 13 are recesses 15, in which grooved rollers 16 are journaled, whereby the carriage is mounted to travel on the track 11. In the bottom of plate 13 are grooves 17 into which the track 11 extends, which serves to prevent derailment of the carriage. At the end of the plate 13 are recesses 18, into which the cleats 12 extend when the carriage is pushed to either end of the track. The cleats serve as a stop when they strike the inner ends of the recesses, and thus prevent the carriage from sliding off the track endwise. By recessing the carriage, as shown, the eX- tent tO which it can travel back and forth is increased, as the stops do not engage the ends of the carriage but enter the recesses.
The device herein described will be found useful and convenient When Working on a large book, as it can be readily shifted back and forth by the bookkeeper to bring the portion desired to the proper position in front of him without the necessity of changing his position or lifting the book.
I claim A book-carrier comprising a base having a track thereon, a carriage traveling on the track and having recesses in its ends, and stops on the ends of the base adapted to enter the recesses.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOHN W. JOHNSON.
