SPECIFICATION forming part of Letters Patent N0. 622,131, dated March 28, 1899.
Application filed June 11, 1898. Serial No. 683,191. (No model.)
To all whom it may concern:
Be it known that I, ISIDOR DREYFUSS, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Paper-Cutting Attachments for Box-Covering Machines, of which the following is a specification.
This invention relates to improvements in machines for automatically cutting off strips of paper or other like material that are being pasted on pasteboard or other boxes; and the object of my invention is to provide a new and improved machine of that kind which is so constructed that the cutters can be ad justed higher or lower and forward or back without requiring any'adjustment of the cutter-operating devices, and which cutting device can be operated by hand at any time to cut out a defective piece of paper without in any way interfering with the automatic operation of the device.
In the accompanying drawings, forming a part of this specification and in which like letters of reference indicate like parts in all the views, Figure 1 is a side elevation of the upper portion of a paper-box-covering machine embodying the features of my invention. Fig. 2 is a plan View of that portion of the machine shown in Fig. 1. Fig. 3 is a transverse view on the line 3 3 of Fig. 2. Fig. 4 is a front elevation of the knives and frame with which they are connected, the main frame being in transverse section and the section being taken on the line 4 4 of Fig. 2. Fig. 5 is a horizontal section on the line 5 5 of Fig. 4. Fig. 6 is a vertical section on the line 6 6 of Fig. 4.; and Figs. 7 and 8 are detail side views of the slide-blocks, gripping-dogs, and mechanism for operating the latter.
The standard A has a base A, provided on its under side with a dovetailed groove for receiving a dovetailed track B, on which said base can slide and on which it can be adj usted, the track constituting a portion of the main frame or bed B of the machine.
A sleeve 0, mounted loosely on the standard A, can be locked on said standard at any desired elevation by means of the screw B, and from the said sleeve the arm Oextends horizontally and is provided at each end with a vertical longitudinally-slotted upright D, in the slots on which the upper knife or blade D is guided to move vertically by means of angle-pieces D which are secured to the end parts of said knife and have laterally-projecting pins D which slide in the slots of the uprights D, the knife being mounted to have a slight slant, as shown.
A rock-shaft E is mounted in upwardly and rearwardly curved arms E of the arm 0 and is provided with two forwardly-extending arms F, each provided at its free end with a longitudinal slot F, into which the pins D on the angle-pieces D enter, so that when said shaft is rocked the upper knife D is caused to move vertically. The said knife D is normally held in raised position by a spring E on the shaft E; but other means may be employed to such end, if desired.
The lower knife or blade G is pivoted at its end below the lower end of the upper knife D to a screw G, as shown at G, that is transversely adjustable in the arm 0 by means of a nut G and the opposite end of the lower knife G is provided with a pin G extending toward the rear and guided in the arm 0, which pin is pressed outward as far as the adjustable check-nuts G permit by a helical spring G surrounding the said pin and bearing against the back of the arm 0.
The rotating shaft H, mounted on the bed B of the machine and which carries the usual frame H for supporting and rotating the box H on which the paper H is to be applied, carries a cam H, fixed on said shaft, and adjacent to the cam a substantially T-shaped frame J is mounted loosely, and in the ends of the arms of said frame a rod K is mounted and guided to slide longitudinally, which rod is pivotally connected at its rear end with a downwardly-projecting arm K of the rockshaft E, so that when said rod K is moved toward the rear the shaft E is rocked and the upper knife or blade D moved downward.
As shown in Fig. 3, the shaft Hmay berotated by an attached worm-wheel H located within a suitable housing H", the worm-wheel H being driven by a worm H connected with any suitable source of power.
Two blocks L and M are mounted loosely on the rod K and are connected in such a manner that they can be moved a short distance toward and from each other on said rod, and this connection is preferably obtained by means of a link I, fastened at one end to one bl0ckfor example, L-and provided at the opposite end with a longitudinal slot 1, into which a pin 1 from the block M passes, as shown in Figs. '7 and 8, which show the two diiferent positions of the said blocks L and M in relation to each other.
A lever N is pivoted atits lower end to the bottom shank of the frame J and its upper end is forked to receive a pin 0, projecting from one side of the block L, a pin on the other side of the block L entering the forked upper end of an angular arm P, attached to the inner side of the lever N, the lower end of said arm P forming a toe P, which runs on the rim of the cam H and is pressed against said rim by a helical spring Q, attached to the lever N, and to a bar Q, attached to the frame J, as shown in Figs. 1 and 2. A gripping-dog R is pivoted in the recessed top of the block M in such a manner that it can engage and grip the rod K and is acted upon by a spring R, which tends to keep the dog disengaged from the rod K.
The block L has aforked arm S, which can act on the dog R to press it against the rod K to engage the same, as shown in Fig. 8. The upper ends of the arms of the frame J are connected by a spring-rod W and is provided at about midway of its length with a shoulder or oifset IV.
A short helical spring T surrounds the rod K between the blocks L and M for the pur-v pose of keeping the blocks as far apart as the link I or other connection permits.
V is a pin or stud projecting from the block M and adapted to engage the shoulder IV on the spring-rod IV.
The operation is as follows: The upper blade D is normally in the raised position and the strip of paper or other material to be applied on the box passes over thelower blade G, as indicated by dotted lines in Fig.2. As the shaft II, carrying the box form or holder, (not shown,) rotates in the direction of the arrow, Fig. 1, it acts on the lever N and its arm P and pushes them in the direction toward the left of Fig. 1 and the two blocks L and M are moved with it, without, however, in any way acting on the rod K, which remains stationary, as does also the upper blade D. Vhen the shaft II and cam H have completed a rotation, the toe I under the action of the spring Q suddenly slides off the highest point of the cam toward the shaft II, and thereby the blocks L and M are suddenly thrown toward the right of Fig. 1 and slide on the rod K until the pin V on the block M strikes against the shoulder IV of the spring-rod W, whereby the block M is momentarily arrested until the tension of said spring-rod is overcome. Thereby the block L is caused to approach the block M and the forked arm S of the block L is caused to act on the arm of the dog R, whereby the latter is caused to grip the rod K and move the same toward the right, Fig. 1, and whereby the upper blade or knife D is forced down and cuts the strip of paper passing over the lower blade. The spring T then immediately presses the blocks L and M from each other and the spring R disengages the dog R from the rod K, permitting the spring E or weight E to throw the upper blade D upward and to move the rod K toward the left into its initial position, and so on. The upper blade is thus automatically caused to descend and to cut the strip of paper once for every rotation of the shaft II- that is to say, once for every box coveredas one box is covered for each rotation of the shaft H. As the upper knife or blade D descends to out, it gradually pushes back the lower knife or blade, thus insuring a clean cut and keeping the lower blade sharp.
If at any time a defective piece is to be cut out of the strip of paper, the operator need only seize the rod K and move the same to the rear, whereby the upper blade D is forced down and cuts the strip, and as soon as the said rod K is released the knife or blade D is automatically raised and the rod K moved into its original position without in any way interfering with the mechanism for automatically operating the said blade.
As the entire mechanismfor automatically operating the rod K is supported by the frame J, which is hung loosely on the shaft 11' and can rock on the same, the sleeve 0 can be adjusted higher or lower without requiring any adjustment of the frame J or parts thereon, as said frame automatically adapts itself to the difierent positions of the sleeve 0, and likewise the adjustment of .the standard A forward or back requires no readjustment of the frame J or parts thereon, as the dog B can grip any part of the rod K, and said rod merely slides lengthwise in the frame J without changing its relative position when the standard A is adjusted forward or back.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a box-covering machine, the combination of a box-form-rotating shaft with a pair of cutting-blades, a reciprocating rod for actuating one of the cutting-blades, a frame mounted loosely on the rotating shaft, supporting and guiding the reciprocating rod, a cam on said shaft, and a gripping device for the rod operated by the cam, substantially as herein shown and described.
2. In a paper-box-covering machine, the combination with a pair of cutting-blades, of a reciprocating rod for operating one of the blades, a gripping mechanism for said rod mounted loosely on the same and means for operating said gripping mechanism automatically from the box-frame-carrying shaft of the box-covering machine, substantially as herein shown and described.
3. In a paper-box-covering machine, the combination with a pair of paper cutting IIO blades, of a reciprocating rod for operating one of the blades, a frame on which rod is supported and guided, two sliding blocks on said rod, a gripping-dog on one of said blocks, an arm 011 the other block for operatingsaid dog, and means for automatically shifting said blocks in relation to each other and on said rod, which means are operated from a shaft of the box-covering machine, substantially as herein shown and described.
4. In a box-covering machine the combination with a pair of cutting-blades, of a reciprocatin g rod for operating one of the blades, a frame for supporting and guiding said rod, a movable gripping mechanism on said rod, a lever on the frame and engaging the gripping mechanism and a cam on the box-frame-supporting shaft of the covering-machine, which cam operates the above-mentioned lever, substantially as herein shown and described.
5. In a box-covering machine, a lower cutting-blade pivoted at one end and mounted to yield at the opposite end in a plane with its upper face, and an upper blade mounted to move vertically toward or from said laterally-yielding blade, substantially as herein shown and described.
6. In a box covering machine, the combination, with a blade mounted to move vertically, of a second blade at right angles to the first-mentioned blade, the second blade being pivoted at one of its ends, and a spring act= in g upon the opposite end of said second blade,
serving to press it in the path of the vertically-moving blade as said blade descends, substantially as herein shown and described.
7. In a box-covering machine, the combination with a vertically-moving blade, of a second blade pivoted at one end to an adj ust= able support in a holder, whereby the said second blade is mounted to yield horizontally and a spring acting on the free end of said horizontally-yielding blade and pressing it into the path of the descending blade, sub stantially as herein shown and described.
In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses, this 4th day of February, 1898.
