JAMES B. ALLEN, OF DETROIT, MICHIGAN.
SPECIFICATION forming part of Letters Patent No. 744:,891, dated November 24, 1903.
I Application filed June 6,1903. Serial No. 160,318. (No model.)
To all w7t0m/ it may concern:
Be it known thatLJAMEs BENJAMIN ALLEN, of the city of Detroit, in the State of Michigan, have invented certain new and useful Improvements in Perforating and Round- Oornering Machines; and I do declare the fol lowing to be a full, clear, and exact description of my said invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7
This invention relates to improvements in perforating and round-cornering machines; and its object is to provide a foot-power machine the operating-levers of which are so arranged as to give a maximum amount of power with an expenditure of a minimum amount of force and to combine in one machine the advantages of round-oornerin g and perforating machines.
One object of this invention is to provide a machine in which the corners of paper can be out at any angle or size by the changing merely of knives, so that by an easy and quick read justment the round-cornering knives may be removed and punches and dies of different size and varied shapes inserted. levers are also so arranged that the paper may be compressed by one foot when round-cornering and the knife operated easily with a minimum expenditure of power by the other foot at the same time. The use of the kicking motion of the foot forward to operate the lever takes advantage of the strongest muscles of the leg beingused at the moment when the greatest force is needed to make a quick and powerful incision without burring or crumplin g the paper.
Figure I is a side view of the machine with a supporting-leg of the frame removed, showing the U shaped compressor-bar and roundcornering knives affixed to the machine. Fig. II is a front view of the said machine. Fig. III is a detailed view of the main operating parts of the machine with part of the operating-table broken away to show the parts hidden thereby. Fig. IV is a side view of the machine, showing the punch and stripper ready for operation. Fig. V is a detailed view of one of the round-cornering knives.
In the drawings, A is one leg of the supporting-frame; B, the table thereon.
O is an inside lever with foot-treadle at- The foottached working upon the rock-shaft J and having attached thereto the verticallyadj ustable bracket D.
E and F are thetwo levers which operate the sliding bar II, the said lever F being fulcruined at the point G in the upper frame, the sliding bar H working in two engaging slots in the said upper frame.
I is an adjustable stop for preventing the forward end of the lever F driving the knife orpunch too far into the die.
K is one of the round-cornering knives.
L shows the compressonbar, working in slots in the table and being attached to the horizontal bar M, which is operated by the rockarm N, which is itself attached to the rockshaft J and is operated when round-cornering by the outside lever with foot-treadle attached at O. The helical spring P engages a projection upon the supporting-frame A and therefore tends to press the rock-arm down ward.
Q, is a vertical sliding bar attached to the U- shaped compressor -bar, to which is attached the compressor-foot R.
S S are two gages used with the round-cornering machine at right angles to one another attached to the table by set-screws and so arranged that their sides are an extension of the sides of the round-cornering knives.
T is 'a punch for perforating.
U is a stripper used for preventing the rising of the paper upon the return motion of the sliding bar II with the punch T.
Stripper U is adjusted by means of the setscrew G.
V is a long gage used in punching. \V is a small gage working in a slot in said long gage and at right angles thereto. The said long gage V is adapted by the gages X, working in slots in the upper frame, to be adjusted to any position desired by means of set-screws Y Y.
The compressor-foot R is so designed that it will come as close as possible to the round cornering knife when in operation, so as to prevent the sliding of the paper during the passing of the knife through it and also to prevent burring of the edges of the paper.
Z is a slot in the table, in which are inserted different shapes of dies when perforating and a wooden blank for use with the round-cor nering knives. The said dies are secured in place by two set-screws H II.
In operation the round-cornering knives are affixed to the sliding bar H by a set-screw or other suitable means. The U-shaped compressor-bar is passed through slots in the table and attached to the horizontal bar M by means of the nuts on the lower side of said bar adapted therefor. The compressor-foot R is attached to that part of the compressorbar which works in a slot in the frame, and the gages S S are set in position so that their lines are an extension of the sides of the round-cornering knives and the edges of the paper may rise against their sides. The left foot then presses the lever 0, raising the compressor-bar during the insertion of the paper. The foot is then brought forward, forcing down the said compressor-foot and keeping the paper in place. The lever O is then rapidly pushed forward, operating the levers *and the sliding bar H and bringing down the round-cornering knife K with great force and removing the corners of the paper. The helical spring P is also so adapted that there is no necessity to hold the treadle 0 forward to keep the compressor-foot and paper in place. As soon as it is adjusted the spring holds the compressor-bar during the operation of the treadle O.
In operating the machine as a punch the nuts on the lower side of the compressor-bar M are removed,and the U shaped compressorbar Land the compressor-foot R and the horizontal bar M arealso removed, together with the gages S S. The stripper-foot U and the punch T are then adjusted in their positions and also the proper die in the slot Z, the dies being held in position by set-screws, and
the machine becomes a perforating-machine by the operation of the treadle C.
The simplicity of the change from one machine to the other is apparent.
