OF FITGHBURG, MASSACHUSETTS, A CORPORATION OF MASSA- METHOD OF FORMING THE CLASPS OF TEE INTERLOCKING PORTIONS OF EXTENSIBLE FRAMES FOR SAW-BLADES OR OTHER TOOLS.
Specification of Letters Patent.
Patented July 13, 1909.
To all whom it may concern;
Be it known that I, ALFRED M. REMING- .TON, a citizen of the United States of America, residing at Fitchbur in the county. of
W'orcester and State of hiassachusetts, have invented an Improved Method of Forming the Clas s of the Interlocking Portions of Extensib e Frames for Saw-Blades or other Tools, of which the following is a specification.
The invention relates to the method of forming upon the ends of the two portions of extensible frames, the loops or clasps which interlock and slide over the respective parts; and it consists in slitting the end of the metal bar which is to form each ortion of the frame, spreading the two portions of the slitted end in opposite directions until they stand at rights to the length of the strip, but in the same plane as the width of the strip, bending these two spread ends at right angles to said plane, interlocking the bent ends of each portion of the frame with the companion strip of metal and finallybending such ends of each over the poltion of .the frame with which they are interlocked. I
This method is especially adapted for making the 100 )s or clasps for the interlocking portions oi extensible frames for sawblades such as hack andbutchers saws.
In the drawin s where the several steps of the method are i lustrated, Figure 1 shows a bar with the end slitted; Fig. 2, the slitted ends bent at right angles to the length of the bar; Fig. 3, those ends bent at right angles to the width of the bar; Fig. 4 shows such ends interlocked with and bent over the compan- I011 stri or bar of metal; Fig. 5 shows the ends oi the two portions of an extensible saw-frame interlocked by clasps made according to my method.
The bar of steel B is slitted at s;the ends 6, e, on each side of the slit are bent outward at right angles to the length of the bar, in the same lane with its width, these ends are again out at right angles to the width of the bar, as shown in Fig. 3, and after the respective ends, thus bent, have been interlocked with the companion bar of the extensible spreading the two portions of the slitted ends at right angles to, and in the same plane as the width of the strip, bending the two spread ends at right angles to the said plane, interlocking the bent ends of each portion with the companion strip and bending such ends together over the strip with whichthcy are interlocked.
