ANDREIV J. DA'WDY, OF GOSI'IEN, INDIANA.
SPECIFICATION forming part of Letters Patent No. 425,306, dated April 8, 1890.
' Application filed June 20, 1889! Serial No. 314,945. (No model.)
To all whom it may concern.-
Be it known that 1, ANDREW J. DAwDY, a citizen of the United States, residing at Goshen, in the county of Elkhart and State of Indiana, have invented certain new and use ful Improvements in Printing-Frame Sup ports; and I do 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.
This invention has relation to improvements in devices for supporting sun-print frames and the like at various angles of inclination, and a tally or register for said frames, as will be hereinafter more fully set forth, and particularly pointed out in the claims appended.
In the accompanyingdrawings, Figure 1 is a perspective View of asun-print frame, taken from the rear, with my improved support and tally or register thereon. Fig. 2 is a view of the support removed, and Fig. 3 is an edge view of the register andlocking-plate removed.
Referring by letter to the said drawings, A indicates a blue-print frame, which may be of any ordinary or approved construction, having the usual hinged back pieces l3, carrying the securing-springs C. To the rear side of one of the hinged leaves or boards B is secured a plate D, which is provided at one edge with a semicircular or segmental rack a. This rack is arranged at approximately right angles to the body of the plate and has its teeth bent at an angle of about fifty degrees to receive the spring branch or locking branch of the support, as will be presently explained. Upon the rear or exposed side of the plate D I provide in a curvilinear manner a series of indentations Z2, and number the same from 1 to l2,although more or less maybe employed.
E indicates a spring arm or finger which is journaled at one end by a screw or like device to the plate D, and its opposite end is curved, as better shown in Fig. 3 of the drawings, so that it may enter any one of the indentations in the plate, and thereby indicate the number of prints that has been taken from the drawings.
F indicates the support for the frame. This support consists of a single piece of wire, having a spring of resilient nature. In forming this support I take a piece of wire of sufficient length and bend it so as to form a single leg or branch I) and a horizontal portion e, which is hinged to the plate of the tally or indicator, said horizontal arm E passing through the indicator-block and having bearings in the side walls thereof, and the opposite end of the wire is carried down in a looped manner, as at f, and its free end bent in an angular position, as at g, so as to form, a guide and stop for the inner branch of the loop-leg of the support when compressed to free its horizontal portion 7L from the teeth a in the segmental rack. The free end of the branch is also bent at an angle, as at 2', so as to form a stop for the inner branch of the loop-leg and prevent the loop from spreading too much. By this construction it will be seen that I have a support which will sustain the frame at any desired angle of inclination by manipulating the looped branch, so as to have .the cross portion h engage and disengage the teeth of the segmental rack. It will also be seen that the support may be turned down upon the frame and occupy but little space in transportation, the indicator being protected to a great extent by the segmental rack.
\Vhile I have shown and described my support as applied to a sun-print frame, yet it is obvious that it may be applied to various other devices, such as casels, cabinet-photos, and the like.
IIaving described my invention, what I claim is l. The combination, with a frame, of a toothed segmental rack secured thereto and a hinged support formed from wire, one of the legs of the support being looped and formed with a straight portion. to engage theteeth of the rack, substantially as specified.
2. The wire support formed from a single piece, having a single leg and a loop-leg, the loop-leg having the end of one branch bent to form a straight portion, and a guide portion terminating in a stop to limit the spreading movement of the loop-leg, in combination with a semicircular or segmental rack having its teeth disposed so as to be engaged by said straight portion of the loop-leg, substantially as specified.
3. The combination, with a sun-print frame, of a plate secured to the rear side thereof and having a series of indentations, and also a toothed semicircular plate arranged at an angle to the indented plate, a pivoted indicator adapted to travel over and enter the indentations, and a hinge-support provided with a yielding branch adapted to enter the teeth of IO the semicircular plate, substantially as specified.
In testimony whereof I aifix my signature in presence of two Witnesses.
