JOHN J. HILL, OF CHICAGO, ILLINOIS.
DEVICE FOR FACILITATING COPYING.
SPECIFICATION forming part of Letters Patent No. 489,953, dated January 17, 1893. Application filed June 21, 1892. Serial No. 437,516- (No model.)
To all whom it may concern.-
Be it known that I, JOHN J. HILL, a citizen of the United States, residing at Chicago, in
the county of Cook and State of Illinois, have invented a new and useful Improvement in Devices for Facilitating Oopyin g, of which the following is a specification.
My invention relates to an improved device for rendering the more convenient, particularly, the work of the oopyistin copying from manuscript, printed or other such matter.
To facilitate the operation of copying, it is usual to support the copy in an upright position of proper inclination to bring the matter into convenient visual range and thus avoid the inconvenience that would ensue to the reader of the copy were the copy to rest flat on the table or other surface upon which it is supported. It is common for typewriters to use frames, affording copy-rests, for the purpose referred to g and it is also common to employ line-indicating means with or without such rests, to supplant the requirement for the exercise of the great care and attention that would otherwise be required to be exercised to avoid skipping lines of the copy in the copying operation.
My object is to provide a simple and inexpensive device which shall supplant the copyrest by being adapted, by reflection, to bring the copy, in any convenient position, (thus including the position of resting flatwise on a horizontal surface) one or more lines at a time, into any convenient visual angle with relation to the readeror copyist. Besides, my improved device may afford, at the same time, a line-indicator of especial advantage.
My improvement is illustrated in the accompanying drawings, in which Figure 1 is a broken perspective view of the'devioe, showing it, by way of diagrammatic representation,operatively applied; and Fig. 2 is a somewhat enlarged sectional view taken at the line 2 on Fig. 1 and viewed in the direction of the arrow.
Generally stated, myimproved device comprises a suitable frame supporting two reflectors (which may be ordinary mirrors, or magnifying or diminishing ones) arranged in such position with relation to each other in the frame and with one in such relation to the open base or side of the frame, that the reading matter of the copy will be reflected, in inverted condition, on the one mirror, which will again reflect it in right position to the desired angle of convenient vision of the reader of the copy.
The best construction, as to details, so far asI have been able to ascertain, for my improved device, involves a frame A comprising a flat oblong base 4" having end-pieces, q, g, at its opposite ends, affording bearings for the ends of strips 19 and 19' carrying reflectors or mirrors B and B. The strips 19 and p, which I prefer to form of sheet-metal with their edges bent over, as represented, to over lap and confine the reflectors along their longitudinal edges, should, for convenience, be pivotally supported to render them adj ustable with relation to each other, and to render the reflector B adjustable with relation to the open portion to of the base of the device, through which the copy is reflected. To render the strips thus adjustable, I provide each at its opposite ends with ears 0, through which set-screws n extend from the end-bearings q- To apply my improvement the device is used as follows: The copy, represented at O as a sheet with the single word hand upon it, may rest, and is preferably intended to rest, flatwise upon a horizontal surface, such as the horizontal top of a table or desk. The device rests at its base upon the copy 0, and the reflector B is turned to such an angle with relation to a line, represented by the word hand, (or more than one line) of the copy as to reflect it, through the open base 00, upon the reflector B, the adjusted position of which is such as to again reflect the reflected matter to an angle convenient to the vision of the user, as represented in Fig. 1. By moving the device from line to line, or from covering a series of lines to covering another series thereof, it serves as a line-indicator as well as a reflector.
What I claim as new and desire to secure by Letters Patent is- 1. In a device for facilitating the reading of copy, the combination with a suitable frame having an open base and adapted to rest at its base on the copy, of a pair of reflectors occupying relative positions the one to reflect the copy upon the other and the latter. to
again reflect the reflection into the angle of vision of the user, substantially as described.
2. In a device for facilitating the reading of copy, the combination with a suitable frame having an open base and adapted to rest at its base on the copy, of a pair of reflectors adjustable into positions to cause the one to refleet the copy, through the open base, upon the other and the latter to again reflect the reflection into the desired angle of vision of the user, substantially as described.
3. A device for facilitating the reading of copy, comprising, in combination, a frame A formed with a base r and end-pieces q, and
reflectors B and B pivotally supported on the I 5 and 1) having ears 0 at their opposite ends, 20
set-screws 'n supporting the strips at their said ears on the end-pieces, and reflectors B and B fastened on the strips, substantially as described.
