FRIEDRICH SCHREIBER, OF M'll'I-ILHAUSEN, GERMANY.
STAMPING-KNIFE.
To all whom it may concern:
Be it known that I, FRIEDRICH Sonnrmnn, a subject of the German Emperor, residing at Miihlhausen, Thuringia, Germany, have invented certain new and useful Improvements in Stamping-Knives, of which the following is a specification.
The present invention has reference to knives or dies for stamping out leather, cardboard or the like, and, in particular, to knives or dies for stamping out shoe soles.
It proposes, briefly, an improved implement of the character specified having its circumferential wall formed with spaced, upstanding projections providing apertures therebetween for the passage of the hands of the operative, thus permitting convenient handling of the implement due to its reduced weight, as well as avoiding the danger to which the operative has hitherto been exposed.
More especially, however, the invention comprehends a construction of sole-cutting knife or die in which the above-mentioned projections are so arranged that, while occupying a minimum portlon of the aforesaid wall, they will give support Where most needed, one of these projections being located at the toe end of the knife and one at the heel end thereof, the remaining projections being disposed close together on opposite sides of each of the sharply-bent, middle portions of the knife. In consequence of this arrangement, the narrow, rear half of the knife is left readily accessible, and the operative may grasp the knife wall at any point with perfect safety, which is a matter of very considerable importance when he has no time, or is not in position, for deliberate choice.
An embodiment of the invention is illustrated in the accompanying drawing, in which:
Figure 1 is a side elevation; Fig. 2 is a plan view; and Fig. 3 is a transverse, vertical section on line A--B, Fig. 2.
Specification of Letters Patent.
Application filed November 13, 1913.
Patented Nov. 3, 1914.
Serial No. 800,831.
As shown in said drawing, the entire circumferential wall or body of the knife is provlded with apertures b, which may be obtamed by cutting away the upper portion of said wall. The formation of these apertures results in the production of upstanding proections a therebetween, as will be understood, the said apertures being relatively wide, and the projections, in consequence, relatively narrow, so that the latter occupy only a minimum portion of the circumference of the knife. The projections are arranged in the manner previously stated: that is to say, there is a projection at each end of the knife, and a pair of projections close together on opposite sides of each of the sharply-bent, middle portions of the knife, such arrangement enabling the operative, not only to grasp the narrow rear half of the blade, which is thus left accessible, but also to insert his fingers into any one of the apertures. Accordingly the knife can be readily manipulated with perfect safety by the operative irrespective of his position with respect thereto, and with either hand, or with both hands, owing to the fact that the apertures extend entirely around the wall of the knife and are deep enough to prevent the fingers from coming into contact with the descending stamp.
I claim: A knife for stamping shoe soles having the upper portion of its circumferential wall cut away to produce a narrow, upstanding projection at each end of the knife and a pair of similar projections arranged close together at opposite sides of each of the sharply-bent middle portions of the knife.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
FRIEDRICH SCHREIBER.
