Description
`THOMAS MARTIN sanitaria or NoRnIs'rowN, PENNSYLVANIA; i
Letters Patent No. 106,080, lated .August 2, 1870.
IMPOVEMENT 1N .PHoToGRAPHre PRINT-commet APPARATUS.
The Schedule referred to in these Letters Patent and making part of the same I, THOMAS MARTIN SAURMAN, ot' Norristown, -conntyof Montgomery, State of' Pennsylvania, have invented an i Improved -'.Photogx'aphic Print-cutting Apparatus, of which the followingis a specification.
Natura and Object of the Invention..
My invention consists, mainly, in the combination of a revolving table, capable of moving vertically, with a ibrming-plate, supported by a iixcd arm or frame, as fully `described hereafter.
`The print is clamped ,between the table and the forming-plate, and trimmed to the shape ot' the latter as the table is revolved, 'and thetable is lowered by means of a trcadle, in order to release the print, when the operation is completed.
Description of the Accompanying Intraday.
Figure l is a side elevation of' my improved photographic print-cutting apparatus;
liigure 2, a sectional view of the same;
Figure 3, aplan view of the revolving table and former; and
Figure 4, an enlarged sectional view of` the upper portion of the apparatus, l
s General Description.
A represents any suitable stand or table, to the top o` which is fixed an arm or frame, B, the lat-ter snpporting, at its outer end, avcrtical 'rod or spindle, (l, to'which the forming-plate F is secured.
The standAhas also, two projections or brackets,
y c," provided withbushes or bearings, b, through which ,passes a vertical rod, I-I, which is directly beneath or in `line witlrtbe spindle G.A
To the upper end of this rod H is hung, in such a mannerthat it can be readily rotated, a table, J, which is constantly forced up to and held against the forming-plate F by a spring, c', wound upon the rod, and bearing against its collar c, and against one of the The revolving table can be depressed, so as to withdraw it from the forming-plate, by means ot an arm or treadle,f, at the lower extremity ot' the rod H.
If the spindle C merely revolved in the arm A, and hadno lateral motion whatever, very accnrate'tting and adjusting of the partswould be required to bring vthe said spindle directly over the rod H, so that, when the revolving table was inl contact with the formingplate, the latter might lie flatly and squarely upon the same. H
ln order to avoid the expense of'this extremely accurate fitting, I have so arranged the forming-plate that it rnayyield, and adapt ,itself to the revolving table.
rlhis I have accomplished by, in the first place, permitting the spindle toswing or. oscillate, to a limited extent, from its bcaringsin the xed arm; and, secbndly, by intervening a gum, leather, or other l washer, @between the yoke j, to which the formingl plate is secured, and the lower end of the spindle or block 7c, secured tothe same, (see iig. 4.)
-to prevent its withdrawal from the arm when the rel volving table is lowered.
The operation ofthe above apparatus is extremely simple. The revolving table is first lowered, by means ot' the treadle, so as to withdraw it from the forming-plate, when the photographic print or picture to be trimmed is placed upon the said table, the tread-` Ie being then released, when, by the action of the spring c, the table. will be caused to rise, thus iirmly clamping the 1n'i1'1tbetweeu the same and the forming-plate.'
lhe edges ci' the print, which project beyond the form, are then trimmed'oi by a suitable cutter o1" knife, as the table 'is revolved, and, when the operation is completed, the table is depressed by means of the tre'adle, the print yremoved and replaced by a second, which is treated in a similarmanner.
The forming-plate may be square, round, oval,`or
of any other desired shape. It may be made ot' metal, glass, or other suitable material, and can be secnredtothe yokej by rivets, clamps, or other appropriate 'hstenings.
A principal advantage which myinvention has over i strut @Milice others ot'its class is that the print, while being trimmed, A d
'is clamped between the bed and form, and vthus se-v curely held by the action of a spring, so that there can be no danger of slipping, as when the pressure is exerted by the foot ot' the operator acting upon a treadle.
Claims.
tically, with a former, supported by a iixed arm or frame. i p
2. rlhe sliding. rod H, for the support of the revolving table, maintained in an elevated position by a suitable spring, and arranged to be depressed by a treadle, or its equivalent, as specilied.
3; Ihe former F, of metal, glass, or other suitable material, secured to a spindle, 0, hung to and arranged to revolve ill the fixed arm or frame B.
4. The said spindle C, hung to the fixed arm, substantially in the manner described, so that it may oscillate as welt as revolve in the said arm. y
5. The 'washer fi, intervening between the yoke j, to which the former is secured, and the lower end of the spindle or block attachedto the same.
In testimony whereof I have signed my name to this specification inv presence ,of two subscribing witnesses.
