` IMPROVEMENT IN SAWGAUGES.
Specication forming part of Letters Patent No. 124,906, dated March 26, 1872.
Be it known that I, WARREN l?. MILLER,
of the city7 county, and State of New York,
have invented a new and useful Implement for Regulating the Side Set of Circular Saws; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of' the same, reference being had to the annexed drawing making a part of this specification, in which- Figure l is a perspective view of the gauge; Fig. 2, a longitudinal transverse section. Letter a, blade,vto which all the other appliances are attached; letters b b, springs on either side of the blade; letter c, square tenon on the bridge d; letters d d, folding bridge;
letters e e, rivets; letters ff, nut for screw t; letter j, end of gauge-screw; letter lo, stud to gauge the left-hand side of sawtooth; letters g g, lugs through which the gauge-screw h passes; letter h, gauge-screw to gauge the right-hand side of the teeth.
rlhe nature and object of my invention consist in providing a cheap and convenient tool with which sawyers can regulate the spread or set of their saw-teeth with greater accuracy and facility than has been heretofore accomplished.
To enable others skilled in the art to make and use my invention, I will proceed t0 describe its construction and operation.
I construct the blade a of steel, in form and thickness as shown, pierce it for the rivets, and also for the bridge dto pass into, and turn and fold to the side. The two springs b b are formed of steel, pierced for the rivets, and
i tempered; then secured in place with rivets,
as shown. The bridge I cast of any suitable metal, with the square stud c attached. The hole in the blade is sufliciently large to permit the stud tov turn. The circular hub of the bridge keeps the stud central, while the stud, in turn, keeps the hub iii-position, being acted upon or pressed by the two springs, which lock the bridge open or folded to the side, as shown in Fig. l. The lugs g g, with gauge-stud 7c,
also nut f, are cast of brass or iron, with rivets attached to secure them to the blade.
To employ the gauge, you will first open the bridge so that it will stand at right angles with the blade, as shown in Fig. 2; place it against the saw; the feet of the bridge and the adj Listing-screw t' will only touch the plate;
-pass the tooth to be regulated between the stud k and screw j. The screw i will adjust the stud 7c to indicate the necessary projection ofthe teeth on the left-hand side of the saw, and the screw h the right-hand side of the teeth.
It will be seen that the stud 7c and point of screw j are not in line--i. e., opposite. The object in placing them thus is that they will not both come in contact with a tooth at the saine time, for with gauges so constructed it is very difficult to determine which gaugingpoint hits the tooth; such difficulty I wish to t avoid.
It will be seen that when j is in position to gauge, the set 7c will be distant, but may beinstantly brought in position by a slight lateral. movement, and vice versa.
The object of making Ithe bridge to fold is t0 protect it from being broken when not in\ Witnesses DAVID M. EDsALL, JNO. S. WOODWARD.
