THEODORE T. CARLSON, OF FITCI-IBURG, MASSACHUSETTS, ASSIGNOR TO SIMONDS MANUFACTURING COMPANY, 6F FITCI-IBURG, MASSACHUSETTS, A CORPORATION" OF MASSACHUSETTS.
SEGTIONAL MACHINE-KNIFE BLADE.
Application filed April 21, 1917.
To all whom 2'25 may concern:
Be it known that THEODORE T. CARLsoN, a citizen of the United States of America, residing at Fitchburg, in the county of l/Vorcester and Commonwealth of Massachusetts, has invented an Improvement in Sectional Machine-Knife Blades, of which the following is a specification.
The invention relates to the construction of long blades for knives for use more particularly in machines, and consists in the manner and means by which the sections of the blade are joined together.
Long blades formed of one strip of metal, are diflicult to manufacture and involve great expense in the process, as compared with that of short blades or sections which are fastened together. The high carbon steel for the cutting edge must be welded to the soft steel back, which is a ditlicult operation in a long blade, and also it is difficult to temper them evenly.
This invention relates to knives adapted for cutting or splitting thin materials, and consists in a blade made up of relatively short sections cut transversely thereof, with the ends of the sections formed so as to closely abut and preferably, with a narrow groove or chamber in the abutting ends of each section, in these grooves is fitted a metal plate, preferably steel, which extends across the joint between the contiguous ends of the sections, and the whole is secured together by rivets passing through the metal on either side of the narrow chambers and through the plate inclosed therein. The connection between the sections may be made by forming the narrow chamber in one end of each section and the connecting plate to be inclosed therein, on the opposite end of each section, so that when the several sections are assembled the projecting plate upon the end of one, will fit into the narrow chamber in the end of the adjoining section, and the rivets will pass through these interlocking portions.
topics of this patent may be obtained for five cents each, by addressing the Gomznissioner of Patents,
Specification of Letters Patent.
Patented Apr. 9, 1918.
Serial No. 163,687.
In the drawings forming a part of this specification, Figure 1, 1s a side elevation of the contiguous ends of two sections of a knife-blade with the inserted connecting plate indicated bybroken lines, and showing the heads of the rivets by which the whole is secured together; Fig. 2, is an end elevation of one section of a blade, with the connecting plate out upon the junction line between two sections; Fig. 3, is a plan view of the joined sections illustrated in Fig. 1, looking upward; Fig. 4, is a similar View with the connecting plate made integral with one of the sections. 7
Referring to the drawings by reference characters, 1, are the several transverse sections of a knife-blade, 2, the narrow chambers or grooves in the ends of the sections, 3, the connecting plates fitted to said narrow grooves, 4, the rivets by which the sections and connecting plates are secured together.
This construction gives a plain unobstructed surface upon each side of the blade, a great advantage for many uses.
1 claim:
1. A knife, consisting of sections cut transversely of the blade and abutting at their ends, and having a narrow chamber in the contiguous ends of each section, a metal plate fitted in the said chambers of the respective sections and extending across the joint between them and the whole secured by rivets through metal at the sides of the chambers and the plates inclosed thereby.
2. In a machine-knife, sections cut transversely of the blade and abutting at their contiguous ends, and h ving a narrow groove in, at least, one end of each section and in the other end of each a projecting counterpart of such groove, and means applied directly to these parts of the sections, to secure them together by engaging the interlocking parts.
