PAPER-BLANK-CUTTING MECHANISM.
SPEOIFIGATION'forming part of Letters Patent No. 736,783, dated August 18, 1903. Application filed September 17, 1902. Serial No. 123,731. (No model.)
To all whom it many concern.-
Be it known that we, JOHN E. ROBINSON, a resident of the city and county of Philadelphia, and DAVID S. IVILLIAMS, a resident of Glenside, in the county of Montgomery, State of Pennsylvania, citizens of the United States of America, have invented a certain new and useful Improvement in Paper-Blank-Cutting Mechanism, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.
Our invention relates to machinery in which blanks are cut from a Web of paper, and is particularly adapted for use with machines adapted not only to cut the blanks, but also to use them, as for wrapping soap or any other purposes.
The special object of our invention is to enable a web of paper to be printed with labels, pictures, or the like, which it is desired to have appear upon the blanks and then to be severed into blanks having the printed matter properly disposed thereon, and we accomplish this by forming in the web of paper, at the time it is printed, a series of perforations occupying a definite position on the web with reference to the printed matter and constructing the paper-machine with intermittently-acting paper-feeding devices adapted to feed the paper forward to the cutters at each operation for a distance in excess of the proper length of a blank, and we further provide the machine with feed interrupting mechanism arranged to be set in operation by the passage of the openings cut in the web of paper, thus insuring the stoppage of the feed mechanism with the printed matter always occupying practically the same relative position with regard to the cutters which operate iipon'the web during the intervals in the operation of the feed.
The nature of our invention will be best understood as described in connection with the drawings in which it is illustrated in various modified forms.
Figure 1 is a side elevation of a machine having our improvements. Fig. 2 is a plan view of the same machine. Fig. 3 is a perspective view illustrating the feed-interrupting mechanism embodied in the said machine. Fig. 4 is a cross-sectional view through the feed-rolls, the cutters and the contact device of the interrupting mechanism. Fig. 5 is a perspective view of the portion of the web or webs of papers as they are delivered to the cutters. Fig. 6 is a side elevationshowing a modified form of feed-interrupting mechanism. Fig. 7 is a side elevation showing still another modification in the feed-interrupting mechanism. Fig. 8 is another side elevation showing another modification of the interrupting mechanism, Fig. 9 being a plan view of a portion of the same, and Fig. 10 a horizontal section on the line 1O 10 of Fig. 8.
A, indicates the frame of the machine, upon which, as shown, is supported a table A, and, within said table A, a table B, upon which the blanks are delivered when out from the roll.
At B, and C, C, Fig. 2, are shown foldingplates, which form a part of a soap-wrapping device in connection with which we have used the blank-cutting device which forms the subject-matter of our present invention, but as this wrapping mechanism forms no part of our said present invention, we have omitted further illustration of it.
i M, is a roll of the paper which forms the inner wrapper, the paper-web extending therefrom being indicated at m, and M, is a roll of paper consisting of a web which has been webs of paper pass, andwhich draw them fronf the rolls M M, and deliver the web forward over the table A, the webs of paper passing under a cutter, indicated at S, and over a cutter, indicated at S, said last-mentioned cutter being given, at proper intervals, an upward motion so as to cut off the paper against the cutter S. As shown, the cutter S, is secured on pivot-arms-S which are given the proper 5 rocking motion by mechanism not herein shown and which may, indeed, be of any convenient character. The cutter S,-as shown, is formed with a perforation S, through which extends one of the contact-fingers T, to be hereinafter described.
Returning to the mechanism immediately connected with the feed-rolls, as shown in Figs. 1, 2, 3 and 4, the lower roll N, is journ-aled on a shaft N, which shaft has secured to it a gear-wheel N and also a clutch member indicated at N, which clutch member is in engagement with another clutch member N held in contact with it by a spring N and secured to rotate with the feed-roll N. The character of the clutch is such that a forward rotary motion of the shaft N, will carry with it the feed-roll, while a rearward rotary motion of the shaft will not affect the said roll. A rotating motion is given to the gear-wheel N and through it to the shaft N, by a reciprocating rack O, secured on a rod which at its bottom, is secured to a pivoted lever 0 having a cam-roll in engagement with the cam 0 on the shaft H The upper feed-roll Q, is secured on a shaft which is driven through a gear-wheel g, by a corresponding gear-wheel on the shaft N, which, as shown in Fig. 2, lies below gear q and therefore does not show. The shaft in feed-roll Q, is'supported in bearing-blocks, indicated atQ,whichare normally pressed down by springs Q and have extending below said bearings, le ver-arms, indicated at Q Q which are secured to a rock-shaft Q having depending from it an arm Q, with serrated teeth at its bottom. R, is a toothed end of a lever R, R pivoted at R to a lever U, and having secured to the arm R an armature indicated at B supported immediately above an electromagnet R secured also on the lever-arm U.
T, is an electric contact consisting of a spring secured to the cutter S, and having a bent portion extending down through the opening S, in said cutter so as to normally rest on the web m, or on the electric contact T, secured immediately below the opening S, and connecting with the eleetromagnet through the wire T the contact T, acting also, with the electromagnet through the conduit T in which is situated the battery T The leverarm U, is given an oscillating movement by cam U, on the shaft H being held in contact therewith by the spring U The normal forward motion of the feedrolls N, and Q, imparted by the mechanism described is somewhat in excess of the length of-the blank to be cut from the web of paper, but as soon as one of the openings m registers with the electric contacts T, T, said con- 5 tacts close the circuit, energizing the magnet R and drawing down through the armature R the end R of the lever R, R thereby raising the toothed end B, of the arm B, so thatit comes in contact with the toothed arm Q and, when the lever-arm U, is moved backward by its cam U, the shaft Q is turned downward, raising the arms Q Q which, pressing against the shaft-bearings Q, Q, raise them and the feed-roll Q, out of operative relation with the feed-roll N, thereby interrupting the feed and insuring that the operation of the cutters S, S, will sever a blank on a line bearing a fixed determined relationship to the printed matter and to the openings m.
It will be obvious that our invention is capable of embodiment in very many forms of apparatus without departure from its essential features. Thus, for instance, in Fig. 6, the feed-roll N, which may be assumed to be positively geared with the feed-roll Q, and to be fixed to its shaft N, is actuated through a gear n fixed on the shaft N, through a gear V, which is journaled on a shaft V and has secured to its end a ratchet-wheel V".
V, is a lever-arm pivoted on the shaft V, and actuated through a connecting-rod V, by a cam, such, for instance, as is indicated in Fig. 6. The lever-arm V, has pivoted upon it a pawl V which is normally in contact with the ratchet-wheel V but which has attached to it an armature r placed in operative relationship with an electromagnet R said electromagnet being situated in a circuit having closing terminals such as already described. The operation of this device is to impart an intermittent forward rotary movement to the feed-rolls, the stroke of the leverarm V, being sufficient to give a motion to the paper somewhat in excess of the paperfeed, the pawl V being withdrawn from operative position by the energizing of the magnet due to the closing of the circuit which occurs, as before, when the electric contacts come above and below the opening Z in the web of paper.
As shown in Fig. 6, a circuit-wire T leading from the electromagnets connects with a spring-contact 15 which moves in contact with another spring-contact t electrically connected with a wire T", leading to the battery T from which another wire T connects through a post 25 with the springterminal T.
In Fig. 7, the device is very similar to that shown in Fig. 6, except that the pawl V is provided with a projecting arm V The electromagnet is, in this modification, secured to the frame of the machine, and the armature R coupled to the arm V, of a lever V V pivoted on a fixed support at V and having its arm V serrated so as to engage the arm V of the pawl when the lever is moved by the electromagnet. It will readily be seen how this engagement will at once disengage the pawl V from the ratchet-wheel V and arrest the motion of the feed-rolls.
In the modification illustrated in Figs. 8, 9, and 10, the feed-roll N, is secured to the shaft N, which has also secured to it a ratchet- IIO and this disengagement of the pawl is efiected' by the toothed arm 0 of a lever 71?, o", pivoted at '0 and carrying an armature R in opera-v tive relationship to the electromagnet The modifications illustrated and described will be suflicient to indicate the broad scope of our invention which, as we have already stated, is capable of embodiment without departure from its essential principles, in a great number of forms of apparatus.
Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. In a machine for cutting blanks from a web of paper, the combination withblank-cutters, of paper-feeding mechanism, adapted to intermittently draw the web of paper forward to the cutters and for a distance in excess of the length of a blank, and mechanism for interrupting the feed, arranged to be set in operation by the passage of perforations cut in the paper-web.
