JOHN A. ROBERTSON AND GARSHOM A. RIGGES, OF ROCHESTER, NEW YORK, ASSIGNORS TO EASTMAN KODAK 00., OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.
Application tiled November '7, 1910.
To (1M who), 2'! may concern:
3e it known that we, Jenn A. Ronnn'rson and (lansuoar A. lticos, both of ltochester, in the county of llalonroe and State of New York, have invented certain new and useful lmproven'ients in Triminingdvlachines; and we do hereby declare the following to be a full, clear, and exact description ol? the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-nurnerals marked thereon.
The present invention relates to sheet sev ering devices and it has for its object to provide a simple and cheaply constructed i'nachine of this character adapted more particularly for t-rimn'iing oil the edges ol paper and other sheets with rapidity and convenience, the improvements being directed in part toward producing an arrangement of the knives or cutters whereby they are maintained in a proper relation to operate at all times with maxinuun elliciency.
A further object oi the inventirm is to provide an improved means :lt'or aiding the operator in n'iaking the cut at a given dis tance from an interior point on the sheet, as, for instance, in cutting a )hotographie print so as to produce a blank border about the picture area.
To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel :teatnres being pointed out in the claims at the end of the specification.
In the drawings: Figure 1 is a perspective view of a cutting machine constructed in accordance with and illustrating one embodiment of our invention; Fig. 2 is a fragmentary rear elevation, Fig. 3 is a vertical section on the line 3-3 of Fig. 2; Fig. l is a top plan view, and Fig. 5 is a vertical section on the line 5-5 of Fig. 4t.
Similar reference numerals through the several figures indicate the same parts.
The machine illustrated in the present embodiment of the invention is designed especially for trimming photographic prints and comprises a suitable supporting structure 1 having end boards or members 2 between which is arranged a rocking work table 3 journaled in or pivoted to the members 2 at a. One side of the table is held Specification of Letters 'Patent.

Serial No. 591,044.
normally depressed by springs 5 interposed between the other side on the opposite side ol? the pivot l and the support l. and the edge ol this normally depressial portion is titled with a suitable blade (5. A second blade 7, :lorining a shearing couple with the lirst is arranged above the same and has its ends 8 journaled in the support 2 or, in the present instance, in brackets S) thereon so that the blade may swing on a longitudinal axis in a lateral direction.
'lhe supports 2 are provided with recesses ll) preferably opening on the under side and contini'ling out through one end at 11, in which recesses are housed coil springs 12 attached to the supports at one end at 13 and at the other end to draw heads 14; carried at the respective ends of the blade 7 and removed from the pivots 8 thereof. These springs have a normal tendency to rock the blade inwardly or toward the work table.
The upper blade 7 prclierahly has its cutting edge arranged at an inclination to the work table in a plane substantially perpemlicular thereto in order to produce the well. known shearing cut and the blade is also arranged at a slight angle to the cutting edge oi. the blade (3 in a direction substantially parallel with the plane of the work table so that when the lower end of the blade T comes into initial. cooperation with the blade (3 to begin the cut the opposite end thereof slightly overlaps the cutting el lge ol the correspmldlug end ot the blade (3. As the relative movement of the blades is continued to complete the cut, the blade 7 yields in a direction laterally of the plane of cutting movementon its pivot 8 under the contact oil" the blade 6 so that at the con1pletion of the cutting operation the cutting edges of the other ends of the blades are correspondiugly separated, as shown in Fig. -l-, though the ends that complete the out are in proper operative relation. The springs '12 resist this yielding movement and maintain the blades in intimate contactso that while no very line adjustment thereof is relpiired the cutting edges, even if some what roughly" iliorined or worn down, operate with great e'lliciency at all times.
The lower blade (3 is the one which, in the present. instance, moved relatively to the other and when lowered the blade 7 is prevented from swinging too far inwardly over the same by any suitable means, as by a stop 15 thereon, that cooperates with the table 3, or its blade 6, when the blades are separated. In use, the sheet is held on the table 3 with that portion of its edge which is to be severed projecting beyond the cutting edge of the blade 6 whereat a downward pressure on the table 3 in the neighborhood of the spring 5 rocks the table and operates the shearing couple.
At the sides of the work table are guiding strips 16 and 17 against which the sheet is held true, one of them being preferably divided into units of measurement. In the present instance these strips also serve to support, in spaced, parallel relationship with the surface of the table, a third guide or guard strip 18 arranged parallel with and adjacent to the shearing couple beneath which uard the sheet is passed and which is useful, for instance, when the print being operated upon has a tendency to curl. In the further practice of our invention we construct this strip of transparent material such as clear celluloid and place thereon a plurality of series of marks A, B, O, D, the series being spaced longitudinally of the strip and the units of each series being spaced transversely of the strip. By the aid of these marks the operator is able to trim the prints with a border of uniform width on all sides to do which he simply brings the edge of the picture area into register with one of the marks which is removed a given distance from the cutting edges of the blade whereat the cut will be made at a corresponding distance and a border will be left of the desired width.
The reason for not extending the marks or lines continuously throughout the length of the strip rather than dividing them up into a numb-er of detached rows or series is to prevent the operator from being misled by a confusion of lines and to the same end we prefer to make the alternate lines or marks of each series of different colors from the intermediate lines so that each mark will be of a color contrasting with that of the adja cent one. Thus in Fig. 4L, the marks 19 are red while the marks 20 are blue.
We claim as our invention:
1. In a trimming machine, the combination with a pair of supporting members having recesses therein opening at the ends thereof and a rocking work table arranged between them and having a cutting edge, of a blade forming a shearing couple with the latter having its ends journaled in the supports at the open ends of the latter and at points above the table permitting it to turn on a longitudinal axis and to yield laterally of the plane of cutting movement by the engagement of the work table during the cutting operation, downward extensions at the ends of the blade in alinement with the recesses of the support and coil springs housed in the recesses of the supports and connected to the extensions at the respective ends of the blade acting to resist such yielding movement of the latter.
In a trimming machine, the combination with a pair of supporting members having recesses therein opening at the ends thereof and a rocking work table arranged between them and having a cutting edge, of a blade forming a shearing couple with the latter having its ends journaled in the supports at the open ends thereof and above the recesses permitting it to turn on a longitudinal axis and to yield laterally of the plane of cutting movement by the engagement of the work table during the cutting operation, draw heads 011 the respective ends of the blade and coil springs connected to the draw heads and housed within the recesses of the supports, said springs acting to resist the yielding movement of the blade.
