UNITED STATES PATENT OFFIQFQ.
GEORGE J. MAYER, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO E. C. ATKINS & COMPANY, OF INDIANAPOLIS, INDIANA, A CORPORATION .OF INDIANA.
MEANS FOR JGINING SECTIONS 0F SECTIONAL KNIVES.
Specification of Letters Patent.
Patented NOV. 17, 1908.
Application filed .Tune 10, 1908. Serial No. 437,640.
To all whom t may concern:
Be it known that I, GEORGE J. MAYER, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Means for Joining Sections of Sectional Knives, of which the following is a specification.
Heavy knives used in some sorts of machines, like veneer machines, are so long that it is diiiicult to secure uniformity of temper throughout their lengths when made of a singlepiece of steel. It is therefore desirable to form such knives in sections. This invention consists in a desirable means of uniting such sections.
A structure embodying my said invention is illustrated in the accompanying drawings in which similar reference characters indicate similar parts.
Figure l is a perspective view illustrating fragments composing the adjacent ends of two sections of aI knife of the character in question, secured together by uniting means embodying my present invention; Fig. 2 a sectional view at the point indicated by the dotted line 2 2 in Fig. l through said uniting means and the immediately adjacent parts, and Fig. 3 a perspective-sectional view through the main member of said uniting means, showing a fragment of one of the knife sections in end elevation, the point of view being indicated by the dotted line 3 3 in Fig. l.
The knife sections 4l and 42 are, except in the formation to receive the uniting devices, of an ordinary and well known form. The adjacent ends of these sections have semicircular notches cut therein, so that, when brought together, a round opening is left between them. This opening, as best shown in Fig. 3, is of one diameter for about half the thickness of the knife sections, and of another diameter for the remainder of such thickness, so that a shoulder is formed at a. The main uniting member 48 is of similar shape and size, so that when it is fitted between the ends of the knife sections (in the opening thus provided) the opening is completely filled, and the structure as a whole presents a smooth and level appearance when the parts are brought together. Two tapered perforations are formed a short distance from the line of separation of the parts 41 and 42 in each of said parts, and these perforations are bisected by the peripheral line bounding the member 43. Corresponding tapered pins 44 are driven into these openings, and all the parts are thus firmly and securely united. The uniting means described secures the knife-sections very firmly and strongly in place, and holds them from any movement relatively to each other. Such uniting means is also very simple and inexpensive in construction, and is easily applied.
Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is:
l. The combination with two sections itting together and provided with semi-circular openings in the adjacent portions, of a circular uniting member fitting into the opening thus formed, and pins inserted in openings in the parts to be united and the main uniting member, said openings being bisected by the peripheral line surrounding said main uniting member.
2. The combination with two sections fitting together and provided with two-size openings in the adjacent portions, of a circular two-size member fitting into the opening thus formed, and pins inserted in openings in the parts to be united and the two-size member, said openings being bisected by the peripheral line surrounding said main uniting member.
3. The combination with two sections titting together and provided with semi-cir cular openings in the adjacent portions, of a circular uniting member fitting into the opening thus formed, and tapered pins inserted in openings in the parts to be united and the main uniting member, said openings being bisected by the peripheral line surrounding said main uniting member.
4. The combination with two sections litting together and provided with two-size openings in the adjacent portions, of a. circular two-size member fitting into the opening thus'formed, and tapered pins inserted in openings in the parts to be united and the two-size member, said openings `being bisected by the peripheral line surrounding said main Limiting member.
5. The combination of two sections having a portion of their adjacent sides cut away leaving an opening between them when brought together, a uniting member fitting into the opening thus formed, smaller openmy hund :md Seal at Indianapolis, Indiana,
ings being provided bisecting the line bethis first day of June, A. D. one thousand tween said uniting member and said secnine hundred and eight.
tions, and pins fitting said last named open- GEORGEJ. MAYER. [111. s] 3 ings and thus securely connecting the uniting VitneSSeS:
inelnber and the sections. CHESTER BRADFORD,
In Witness whereof, I, have hereunto set THouAs W. MCMEANS.
