Be it known that we, SAMUEL F.l CoNANT and HORACE A. MANI-my, of Skowhegan, in the county of Somerset, and State of' Maine, have invented u. new and improved Photographic-Printing Frame; and we do hereby declare "that the following is a full, clear, and exact description thereof which will enable those skilled in the nrt to make and use the same, reference being had to thel accompanying drawings, forming part of this specification. Y Y A y* i This invention relates to a new and improved frame or clamp for ho graphsare being copied or printed therefrom; l

v i The object of the invention is -to obtain aldevice for the purpose specified, which will admit' of the paper the progress of the printing or copying mly retained in contact on the frame. In

the accompanying sheet of drawingsi 'Figure-1 is a plan or top viewof our invention;

Figure 2. a transverse vertical sectionof the same, taken in the line :c z, fig. 1

A represents a block, of rectangular form, and of any suitable dimensions, connected by hinges a a,.tl1e latter being'at the under side, to admit ofthe two p composed of two -equal parts, arts of the block being pressed ed with a. piece of cloth, baise, .b, and a cleat, c, 'is glued, or otherwise attached to tho outer end of each of the two parts of the block. B B represent two clamps, composed each of a cross-bar, d, a spring, e, a loop,f, and a. crossfplate, g. The cross-bars d may be of wood i large enough .to receive tho thumb, as'shown clearly in iig. 2. The springs e are of semi-elliptic form, and are attached at the centres to the bottoms of 'the cross-bars d, and bear. against the bo'ttomsof the loopsf. The loopsf form three sides of a quadrangle, the side portions fitting in grooves or notches at the ends of the crossbars d, and the cross-plates g attached te the upper ends ofthe side portions ofthe loops.

It will be seen, by referring to fig. 2, that the springs e will have a tendenc y to keep the cross-plates g in contact with the upper surface of the block, or the negative, C, uponit. -lhe paper, D,is laid upon the padded surface of the block A, the negative, C, placed upon the paper, and the cross-plates g ofthe clamps placed over the negative, the clamps holding all together. The clamps may be readily adjusted, so that their plates g may rest on any part ofthe negative, by placing the thumb of the right hand in the curve at the centre ofthe crossbar, and thefingers under the bottom of the loopf, and pressing the thumb and `fingers towards each other, thereby compressing the springe and raising the plate g, or increasing the width ofthe space between said plate and-the cross-bar. The plates g cast no shade, in whatever position they may be placed.

We claim as new, and desire to secure by Letters Patentv The block A, in eombination with the two clamps,

B B, all constructed and arrangedsubstantially in the manner as and for the purpose herein set forth.
