IMPROVEMENT IN READING AND COPYING STANDS.
Specification forming part of Letters Patent No.
153,642., dated July 28, 1874; application filed February 7, 1874.
To all whom it may concern:
Be it known that I, CHARLES E. WELLS, of West Pawlet, in the county of Rutland and State of Vermont, have invented a new and Improved Reading and Copying Stand, of which the following is a specification:
In the accompanying drawing, Figure 1 represents a side elevation, partly in section in line 0 c, Fig. 2, of my improved reading and copying stand; and Fig. 2, a top view of the same. Fig. 3 is a perspective view.
Similar letters of reference indicate corresponding parts.
The invention will first be fully and then pointed out in the claim.
A represents a hollow standard, supported on a base, B, and in which is adjustable the shank D of table D. O C is the bracket by which the stand is attached to the table or other device, and E F a collar and hinged arm.
The rack G is hinged to its base-piece G, which is attached by washers and pin to a central pivot, e, of supporting-disk f. which latter slides by its guidepiecej" in the slotted arm F, to be adjusted thereon in any position, as found most convenient. The hinged rack G is set into any inclined position by means of rod g, which enters into a perforated side strip, g, of the same.
The whole rack may be easily detached from the arm, if desired to be used separate- 1y, by disconnecting its base part from the central pivot of the disk f. The rack may be described,
fastened to arm F by hook t of disk f, being placed over lug or staple c of arm F.
The book or other article to be exposed on the rack is securely fastened thereto, after being placed 011 the projecting lugs l at the lower end, by carrying the top slide-piece m, with top lugs l, down. The slide-piece m ent The combination, with centrally-slotted rack G, having lugs Z, and the top slide m, having lugs l, of the pivoted arms a, rods a, and fasteners 0, as shown and described, to fasten the book or other copy to the rack.
