SPECIFICATION forming part of Letters Patent No. 694,490, dated March 4, 1902.
Application filed July 1, 1901. Serial No. 66,675. (No model.)
To all whmn it may concern:
Be it known that I, EARLE W. MURPHY, a citizen of the United States, residing at Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Book-Holders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7
This invention relates to devices for holding books open; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure l is a plan view of the book-holder. Fig. 2 is a side View. Fig;
3 is an end view.
A is a T-shaped frame having a projecting rib along the back of its head to prevent the book from sliding backward off it.
B is a guide-frame which is slidable longitudinally on the longitudinal bar a of the frame. The guide-frame has guides 1) arranged crosswise on its under side, and Care cross-bars which are slidable in the guides 19 parallel with the head of the frame.
D is a clamping-bar pivoted by a bail d to the under side of the front end of the bar a and foldable underneath it. D is a cord for securing the clamping-bar.
E are spring-wire pillars which project upwardly from the opposite ends of the crossbars 0. Each pillar E has a spiral spring e and an arm e. The arm e has a cranked portion fwhere it joins onto the spring e, and
this cranked portion engages with the. mainpillar E. The arm e carries an india-rubber knob or disk 9 at its free end and has a finger-piece g for operating it.
The book is opened and is placed with its back upon the bar a. The cross-bars are slid in the guides b and'the frame B is slid on the bar a, so as to adapt thespring-arms to hold the book in its open position, as shown in Fig. 3, in which the book is indicated in dotted lines; The spring-arms are raised, as
shown, and'bear downward on the pages of the book.
What I claim is- 1. In abook-holder, the combination,with a T-shaped frame having a longitudinal bar, of a guide-frame slidable longitudinally on the said bar and provided with two parallel guides on the under side thereof, cross-bars slidable in the said guides, andpillars provided with spring-arms and projecting upwardly from the end portions of the said crossbars, substantially as set forth.
2. In abook-holder, the combination,with a T-shaped frame having a longitudinal bar, of a guide-frame slidable longitudinally on the said bar and provided with two parallel guides on the under side thereof, cross-bars slidable in the said guides, and spring-pillars projecting upwardlyfrom the end portions of the said cross-bars, each said spring-pillar being provided with a spiral spring connected to its top'portion, a cranked portion projecting from the innercoil of the spring crosswise of the main portion of the pillar, an arm projecting from the said cranked portion, and a knob at the free end of the said arm, substantially as set forth.
3. The combination,with a T- shaped frame having a longitudinal bar, of a guide-frame slidable longitudinally on the said bar and provided with two parallel guides on its under side, cross-bar'sslidable in the said guides and provided with spring-arms for bearing on the pages of the book, and means for clamp ing the two said cross-bars in their guides, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
EARLE w. MURPHY.
