JOHN GRAMELSPAGHER, OF JASPER, INDIANA.
Specification of Letters Patent.
Application iiled September 9, 1907. Serial No; 391,970.
Patented Dec. 3 1, 1907.
To all whom it may concern: 1
Be it known that 1, JOHN GRAMELSPAOHER,
a citizen of the United States, residing at Jas-- per, in the county of Dubois and State of In diana, have invented a new and useful Copy- Holder, of which the following is a specification.
This invention relates to attachments for desks and more particularly to an improved copy holder especially designed for use in connection with type-writer desks.
The object of the invention is to provide a desk having a frame slidably mounted in one of the pigeon holes or compartments thereof and provided. with a spring clamping arm adapted to engage and support a note book or manuscript in convenient position for copying, said framebeing movable to inoperative position within the compartment when not in use.
A further object is to arrange the opposite walls of the pigeon hole or compartment at an angle or inclination to each other so that when the frame is moved to extended position the latter will frictionally engage said walls and thus prevent accidental displacement of said frame.
A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and efficiency.
Further objects and advantages will appear in the following description, it being understood. that various changes in form,
proportions and minor details of construction may be resorted to within the scope of the appended claims.
in the accompanying drawings forming a part of this specification: Figure 1 is a perspective view of a type-writer desk provided with a copy holder constructed in accordance with my invention. Fig. 2 is a top plan view of the copy-holder showing the manner of mounting the same within the adjacent pigeon hole or compartment of the desk. Fig. 3 is a perspective view of a portion of the sliding frame.
Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.
The improved device forming the subject matter of the present invention is principally designed for use in connection with typewriter desks and by way of illustration is shown in connection with a type-writer desk of the ordinary construction in which 5 designates the body of the desk, 6 the flexible top or curtain, 7 the usual pigeon holes, and 8 the sliding table for supporting the typewriter.
Slidably mounted in one of the longitudinal compartments or pigeon holes is'a movable frame including spaced longitudinal bars 9 connected'at their forward ends by a transverse bar 10, the latter being provided with mortices 11 for the reception of tenons 12 formed on the adjacent ends of the arms 9, as shown.
The opposite vertical walls 13 of the frame receiving compartment are arranged at an angle or inclination to each other while the free ends of the arms 9 are slightly diverged so that when the frame is extended or moved to operative position above table 8 the inner ends of said arms will frictiol'i'ally engage the inclined walls of the partitions 13 and thus prevent accidental movement of the frame.
Secured to the interior walls of the partition 13 are strips or cleats 14 which. serve to support and guide the sliding frame when the latter is moved to operative and inoperative position. If desired, however, similar cleats or strips 14 may be arranged above the bars 9 as well as below the same without depart ing from the spirit of the invention.
Secured to one end of the transverse bar 10 is a wedge'shaped block 15 carrying a spring clamping arm 16, the latter being secured to the inclined face of the block 15 in any suitable manner, as by screws or similar fastening devices 17.
The arm 16 is preferably formed of spring metal and is bent inwardly to form a concaved portion 18 adapted to engage the cover or leaves of the book or manuscript, indicated. at 19, the free end of the arm 16 being norm-ally disposed in frictional contact with the transverse bar, as indicated at 20, while the terminal thereof is deflected laterally to form a finger piece 21 by means of which the clamping arm may be readily disengaged from the book or manuscript so as permit the same to be quickly detached from the copy-holder.
In using the device a longitudinal pull is exerted on the transverse bar 10 and the sliding frame moved to a position above the table 8, as best shown in Fig. 1 of the drawing, and in which position the manuscript or other matter to be copied may be'readily suspended from the holderin the direct line of vision of the operator.
As the frame is Withdrawn from the adj acent compartment .or pigeon hole the free ends of the bars 9 will frictionally engage the inclined Walls or partitions 13 and thusprevent removal of the frame from the compartment, as before described.
When the device is not in use the book or manuscript is detached from the spring clamping arm by exerting a lateral pressure on the finger piece 21 and saidframe moved to inoperative position Within the compartment or pigeon hole by pressing rearwardly on the bar 10 and in Which position the frame or holder 'will be effectually housed Within the compartment so as to permit the flexible top or curtain 6 to be moved to closed position.
The copy-holders may be made in different sizes and shapes and may be attached to any form of desk having the usual pigeon holes or compartments.
From the foregoing descrition it Will be seen that there is provided an extremely simple, inexpensive and eflicient device admirably adapted for the attainment of the ends in view.
Having thus described the invention What is claimed is: I
1. The combination With a desk having a compartment the opposite Walls of Which are arranged at an angle to each other, a frame slidably mountedbetween said Walls and adapted to frictionally engage the same for supporting the frame in extended position, and a Work engaging member carried by one end of the frame.
2. The combination with a desk having a compartment, the opposite Walls of which are arranged at an angle to each other, guides secured. to the interior Walls of the compartment, a frame slidably mounted on the guides and adapted to frictionally engage the Walls of the compartment for supporting the same in extended position, and a spring clamping arm secured to one end of the frame and having its free end bent laterally to form a terminal finger piece.
3. The combination W1th a desk having a compartment the opposite Walls of Which are arranged at anangle to each other, guides secured to said. Walls, a frame slidably mounted on the guides and provided ivith spaced longitudinally disposed bars adapted to frictionally engage the inclined Walls of the compartment for supporting the frame in extended'position, and a Work engaging member carried by the closed end of the frame.
4. The combination With a desk having a compartment, guidessecuredto the interior Walls of the compartment, a frame slidably mounted on the guides and including spaced longitudinally disposed bars connected-by a transverse bar, a Wedge shaped block secured to one end of the transverse bar, and a spring clamping arm secured to the block and having its intermediate portion concaved and one end thereof deflected laterally to form a terminal finger piece.
5. The combination With a desk having a compartment the opposite Walls of which,
are arranged at an angle to each other, guides secured to said Walls, a frame slidably mounted on the guides and including spaced inclined bars adapted to frictionally-engage the inclined Walls of the compartment When the frame is moved to extended position, a-
transverse bar connecting the longitudinal bars of the frame, and a Work engaging member secured to the transverse bar, said frame being movable to inoperative position Within the compartment.
' In testimony that I claim the foregoing as my oWn, I have hereto aflixed my signature in the presence of tWo Witnesses.
