EMIL SALTZKORN AND LUDIVIG NICOLAI, OF DRESDEN, GERMANY.
KNIFE FOR CUTTING AND. SCORING PASTEBOARD.
SPECIFICATION forming part of Letters Patent No. 442,738, dated December 16, 1890.
Application filed May 22,1890. Serial No. 352,737. (No model.) Patented in Germany April 21, 1889, No. 50,356; in England April 23, 1889, No. 6,797; in France April 29. 1889, No. 197,841; in Belgium May 15. 1889, No. 86,006, and in Austria- Hungary March 15,1890,No.40 and No. 719.
To all whom it may concern.-
Be it known that we, EMIL SALTZKORN and LUDWIG NIooLAI, subjects of the King of Saxony, and residents of the city of Dresden, in theKingdoin of Saxony,in the German Empire, have invented certain new and useful Improvements in or relating to Knives for Cutting or Scoring Pasteboard and other Analogous Materials, (for which we have obtained Letters Patent of Great Britain, No. 6,797, dated April 23,1889; in Germany, No. 50,356, dated April 21, 1889; in Belgium, No. 86,006, dated May 15, 1889; in France, No. 197,841, dated April 29, 1889, and in Austria-Hungary, No. A0 and No. 719, dated March 15, 1890,) of which the following is a specification.
.The object of this invention is a knife for scoring card-board to be used in the manufacture of boxes and the like.
Owing to its peculiar form, this knife acts upon the card-board at three different points at the same time, and only scores it. By this means the knife is enabled to perform its work more easily and its action upon the cardboard is rendered less forcible than the device used for the same purpose hitherto, and, lastly, a sharper and more serviceable cut is obtained.
In the accompanying drawings, Figure 1 is aplan of the knife viewed from below. Fig. 2 is a section thereof; Fig. 3, a front view; Fig. 4, a piece of card-board considerably enlarged; and Fig. 5, the same piece, also enlarged and bent. at the cut or scored part. Fig. 6 is a side view of a modification of the scoring-knife, and Fig.7 a front v1ew thereof.
To a stock a, preferably of rectangular form, is attached the knife-holder b, which is adj ustable in a groove and carries the improved scoring-knife c. This knife is miteror wedge shaped, as shown at Figs. 1 and 8, and has a straight cutting-edge o. It is flattened at its backward portion, where it is attached to the knife-holder by means of screws. Being embedded in a groove provided for the purpose in the holder b, it is prevented from lateral displacement. In front the knife terminates in a swallow-tail formed of two curved blades or cutters c 0 set at an angle to each other.
The card is supposed to be placed on a table 1, moved along by a carrier or feed-roller to. (See Fig. 2.) iVhen it is thus brought under the knife, the curved blades begin by effecting a flat and rather shallow out, which, however, grows deeper gradually, and the action of the knife upon the card-board is thereby rendered less abrupt and sharp than it would be if the deepest out were made at once, so that card-board of an inferior quality and containing more wood can be operated upon without any fear of the blades slipping off or' of the card-board being torn. This scoringknife also admits of a much easier operation of the machine, this, as well as the advantage mentioned before, being due to the distribution of the resistance over the larger surface of the tool and the various directions of its action. 7 I
In the modification shown in Figs. 6 and 7 the knife, instead of being miter-shaped, has the form of a plowshare. Here, too, however, the straight blade 0 divides into two curved ones 0 c inclined toward each other. The knife is attached to the knife-carrier b by means of its side piece or extension 0 which is screwed thereto by bolts cl d. The plowshare form of the knife permits an easier removal of the chippings, so that the whole surface of the out is better exposed to view.
By the combination of the two curved blades with a straight one a out such as represented in Fig. 4 is obtained. This peculiar shape of the cut is of great advantage in making bandboxes and the like, inasmuch as when the card-board is bent at right angles the gradual y-flattening edges of the cut leave a space between them, whereby some play is allowed to the compressed portions of the joint, and when it is desired to apply the glue within the box the same is by the shape of the cut enabled the better to enter the joint.
We claim- A miter or wedge shaped scoring-knife for card-board or the like, having the straight blade 0' bifurcated at the front end and formed into two forwardly and upwardly curved blades 0 substantially as described.
In testimony whereof we affix our signatures in presence of two witnesses.
