MACHINE FCR SCORING CARDBCARD.
SPECIFICATION forming part of Lettere Patent No. 569,200, dated october 1s, 189e.
Appiieaan'nea septemberie, 1894. Serin No. 523,314. (No meten T 0 all whom, it mm/ concern,.-
Be it known that I, CLARENCE W. HoBRs, a citizen of the UnitedStates, -residing at Worcester, in the County of Worcester and State of Massachusetts, have invented a new and useful Improvement in Machin es for Scoring Cardboard, of. which. the following is a specification, accompanied by drawings forming a part of the same and representing a scoring-machine embodying my invention, in which- Figure l represents a plan View of the ma- Chine. Fig. 2 is an end View, a portion of the mechanism having been removed, on line 2 2, Fig. 1. Fig. 3 is a sectional view on line 3 3, Fig. 1. Fig. 4is a sectional view on line 4 4, Fig. l. Fig. 5 is a detached and side view of the elastic nger by which the cardboard is fulcrumed in order to cause it to be squared by the advancing cross-feed; and Fig. 6 is a sectional view on line 6 6, Fig. 2, showing a side View of the clutching mechanism.
Similar letters refer to similar parts in the different figures.
My present inventionv relates to certain improvements in a double-scorin g machine or one containing two sets of scoring mechanisms placed at right angles-to each other with connected operating mechanism by which a sheet of cardboard is automatically scored in two directions at right angles to each other.
Referring to the drawings, A denotes a feed-table upon which the sheet of Cardboard is presented to the rst of said scoring-knives, and A represents a side gage along which the cardboard is fed in a straight line to the scoring-knives.
B represents a cutter-bar carrying upon its under side a set of rotating scoring-knives B and a cooperating roller B2, (represented in Fig. 4,) the cutter-bar B and roller B2 being shown in sectional view.
The Cutter-bar, rotating knives, and roller B2 are constructed and operate in the usual and well-known manner common in machines of this class.
In the rear of the roller B2 is placed a feedroller B3 and shaft B1, carrying a series of feed-rollers B5, acting with the roller B3 to carry the cardboard forward and deliver it' upon the second feed-table C. The feedtable C is provided with ways C', in which moves a sliding bar (J2, having a series of holes C3 to receive an attaching-screw C4, by which a reciprocating bar C5 is adjustably attached to the sliding bar C2, forming the cross-feed by which the sheet of cardboard which has been delivered upon the second feed-table C- l is moved forward toward the second scoring mechanism, consisting of the cutter-bar D, having the rotating cutters D suspended beneath it, and a roller D, as represented in sectional view in Fig. 3, the scoring mechanism being a duplicate of the first.
A lug E* extends downward from the sliding bar C2 and is connected by a link D0 with a rotating crank-wheel D2, carried upon a shaft D3, which isdriven by the gears D4 D5 from the drivin g-shaft D6 through a clutching mechanism D7,-by which the driving power is connected with the shaft D3 to produce one complete revolution of the shaft and then automatically disengage itself.
The clutching mechanism being of a wellknown form of construction and having been shown and described in detail in United States Letters Patent No. 260,394, dated July 4, 1882, I have not deemed it necessary inthe present application to show or describe the same in detail. A
To the reciprocating feeding-bar C5 is adj ustably attached a stop E, arranged in the path of. the advancing cardboard and designed to'limit its forward movement over the table C. Sliding in the stop E is a rod E', provided with a head E2, against which the advancing edge of the cardboard strikes, sliding the rod E. The rod E is connected with a rod E3, held in the free ends of arms E4 E4, which are attached to a rocking shaft E5, journaled in bearings attached to the end of the bed C. Projecting horizontally from the rocking shaft E5 is an arm E11, to which is pivoted a rod E7, provided with a shoulder E8, overhanging a lever E9, pivoted to the framework of the machine and provided with a shoulder E10, which is held against a shoulder E11 on the rotating clutch by means of a spring E12. As the'advancing edge of the cardboard strikes the head E2 the rod E' is moved forward, rocking the shaft E5 and depressing the rod E7, so the shoulder E8 will depress the lever E9 and carry the shoulder E10 out of the path of the shoulder E11, there-K by allowingthe clutching mechanism to connect the shaft D3 with the driving power and cause it to make one complete revolution, rotating the crank-wheel D2 and carrying the reciprocating bar 'C5 forward, pushing the cardboard on the table C between the roller and rotating cutters of the second scoring mechanism.
The table C is provided with a hole F to receive the upper end of a sliding bar F', carried by one end of a pivoted lever F2, having at its opposite end a counterweight F3, by which the bar is held in its raised position with its upper end projecting through the hole in the table C, as represented in Fig. 3.
The rotating crank-wheel D2 is provided with a cam-surface, which allows the counterweight F3 to raise the bar F in the position shown in Fig. 3 when the reciprocating bar C5 is in its farthest position from the second scoring mechanism, allowing the upper end of the bar F' to project through the table and form a stop, between which and the reciprocating bar C5 the cardboard is entered, the bar F holding the cardboard from displacement. As the crank-wheel D2 is rotated its face acts against a spur F4 on the pivoted lever F2, serving to depress the bar F' and withdraw its upper end below the surface of the table to allow the sheet of cardboard to be advanced toward the second scoring mechanism by the forward movement of the reciprocating bar C5, the bar F being held down until the bar C5 is moved back to its normal position.
The table G is provided with a series of holes G, allowing the stand G/ to be adjustably attached to the table by means of a binding-screw G2. The stand G carries a post G5, supporting a horizontal stud G4, on which is pivoted a bent nger G5, and around the stud G4 is coiled a torsional spring G6, having its tension applied to the finger G5 to carry its free end G7 down into contact with the upper surface of the cardboard lying upon the table C, so the tension of the torsional spring will cause the end G7 of the finger to exert a pressure upon the surface of the cardboard nearly midway between its opposite ends and form a fulcrum about which the cardboard can rotate in order to bring its rear edge squarely against the face of the reciprocating bar C5 as the bar moves forward to advance the cardboard toward the second scoring mechanism.
The finger G5 is bent at G8, forming a camsurface, and the reciprocating bar C5 carries a post H, having a horizontal stud H eX- tending beneath the finger G5, so as to slide beneath the bent section G8 and raise the finger G5 above thetable C as the reciprocating bar C5 moves back to allow a sheet of cardboard from the first scoring mechanism to pass beneath the end G7 of the finger.
As the reciprocating bar C5 moves forward the stud H moves away from the bent secn tion GS and allows the finger to be carried down by the tension of the torsional spring until its end G'f bears upon the upper surface of the cardboard, so as to furnish africtional resistance at the end of the finger, serving as a fulcrum about which the cardboard can be slightly rocked in order to bring its rear edge square with the advancing edge of the reciprocating bar C5, as already described, so the sheet of cardboard will be advanced toward the second scoring mechanism in a line at right angles with the scored lines made by the first scoring mechanism. The finger G5 is made long enough so the reciprocating movement of the bar C5 will take place wholly beneath the finger, and as the bar C5 moves back to its normal position the stud H will again move beneath the bent section GS, raising the free end of the finger sufficiently above the surface of the table C to allow the succeeding sheet of cardboard to enter between the end of the finger and the surface of the table.
The reciprocating bar C5 is provided with an overhanging lip I, beneath which the edge of the advancing cardboard passes, and to the lip I is attached an elastic bent blade I', having its free end bearing lightly upon the surface of the table C, and as the cardboard is moved onto the table C its edge passes beneath the free end of the elastic blade I',
thereby producing a frictional resistance upon the surface of the cardboard sufficient to restrain its momentum.
IOO
An adjusting-screw l2 is held in the lip I,
bearing against the top of the elastic blade, for the purpose of varying the pressure upon the cardboard. The extreme tip of the free end of the elastic blade I rests upon the surface of the cardboard, and as the cardboard is moved forward upon the table C it will raise the elastic blade I' and pass beneath it and the surface of the table, but anyreverse movement of the cardboard caused by a rebound of the cardboard or from any other cause will be checked by the engagement of the free end of the elastic blade with the sur face of the cardboard.
That I claim as my invention, and desire to secure by Letters Patent, is- V l. In a machine for scoring cardboard the combination with a table, a reciprocating bar by which a sheet of cardboard is pushed along said table, mechanism by which a sheet of cardboard is fed upon said table in front of said reciprocating bar, actuating mechanism by which said bar is reciprocated, a clutching mechanism by which said actuating mechanism is connected with the driving power, a yielding stop placed in the path of the advancing sheet of cardboard as it is fed upon the table in front of said reciprocating-bar, said yielding stop being operatively connected with said clutching mechanism,.whereby the reci procating-bar-actuatin g mechanism is autom atically connected with the driving power by the forward movement of the cardboard, substantially as described.
IIO
2. In a machine for scoring cardboard the combination of a table upon which the cardboard is fed to a scoring mechanism, of a reciprocatin g bar by which the cardboard is advanced to the scoring mechanism, a pivoted finger extending over said reciprocating bar and a spring with its tension supplied to said nger to press it downward, said Iinger having a cam-surface arranged to be acted upon by the reciprocating bar, whereby said nger is raised.
3. In a machine for scoring cardboard,'the combination of a table upon which the cardboard is fed to a scoring mechanism, of a reciprocating bar by which the sheet of cardboard is advanced toward the scorinv'mechanism, and an elastic blade having one end attached to said reciprocating bar and having its free end pressing against the surface of the table, substantially as described.
4. In a machine for scoring cardboard, the combination with a table, ascoring mechanism, a reciprocating bar by which the cardboard is moved toward said scoring mechanism, a stop, as E2 arranged in the path of the sheet of cardboard as it is fed in front of said reciprocating bar, and a stop-bar as F projecting above the surface of said table between said reciprocating bar and said scoring of the machine, a stopE adjustably attached to said reciprocating bar, a sliding rod E provided with a head E2 placed in the path of the advancing cardboard as it is placed before said reciprocating bar, whereby the advancing cardboard is made to move said sliding rod, and mechanism connecting said slidv ing rod with said clutch, substantially as described.
