VINCENT SEILER, OF READING, OHIO.

SAW-SET.

SPECIFICATION forming part of Letters Patent No. 303,463, dated August 12, 1884:. Application filed December 31, 1883. (No model.)

Be it known that I, VINCENT SEILER, of

Reading, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Saw-Sets, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure 1 is a side view of my improved saw set. Fig. 2 is .an enlarged front view of the same. Fig. 3 is a perspective view of modi fied form of upper jaw.

The generality of saw-sets in use at present time seem to be lacking in several importantfeatures, among which are, first, the guide-pieces on the jaws are of such a cumbersome nature as to require much valuable time for the operator to adjust properly for different grades of saws 5 second, of a properly-shaped piece for setting the tooth which can be turned in a socket, by means of which teeth of different sizes and thickness can beset with equal facility; and, third, the general arrangement of the parts coming in immediate contact with the saw, so as to obstruct the view of the operator.

In the drawings, A is one of the jaws of a saw-set, and B the other. These jaws are pivoted at G, in the usual manner of this class of Between the outer ends of the handles is placed a curved spring, D, secured to the inner side of one of the handles by means of a screw, D, and has a bearing against the inner side of the opposite handle. The forward ends of the jaws are curved at E and F, so as to place the jaws at a sufficient The upper face of the end of the jaw Ais provided with a square plate, G, with the lower side grooved, as at H, so that the edges I will fit down over the sides of the jaw and be secured in position by means of a screw, J, from the lower side. Sliding backward and forward upon this plate G is a gage-piece, K, the ends extending down over the sides of the plate G, with the lower ends, N, turned inwardly, forming lugs M, so as to clasp the under side of the plate, forming ways which permit it to slide backward and forward, but is held in position relative to lateral movements. One of the vertical ends N is provided with a set-screw, O, for securing the gage-piece K in position at any desired place. The central part of the gage-piece has a semicircular redifferent-sized teeth of saws.

distance apart.

cess, P, and laterally from this recess are upwardly-projecting lugs Q, against which the teeth of the saw abut, thus forming a gage.

Through the forward part of the jaw 13 is a vertical screw-threaded opening, R, within which is placed a threaded bolt, S, the lower end of which is somewhat flattened or oblong in horizontal cross-section to fit the teeth of the saw. The gage-piece K,being adjustable, can be moved backward and forward for the A nut, T, is placed on the bolt S, immediately above the jaw 13, to screw down against the jaw when the bolt is at the place desired, for the purpose of securing the same in position. Upon the upper end of the bolt S is placed athumb nut, S, to facilitate in raising or lowering the bolt in the opening in adjusting the same. Immediately forward of this bolt the jawB is formed square, or nearly so, in vertical crosssection, upon which is placed a sliding piece, U. One of the sides of this sliding piece, preferably the upper, has a set-screw, \V, for securing said piece in position. From the lower side of this piece extend downwardly two arms, X, a little farther than the upper face of the plate G, or of such a length as to have sufficient bearing upon the upper side 7 of the saw to set the tooth as much as may be desired. The sliding gage-piece has by its peculiar construction a firm hold on the piece G, while the set-screw 0 gives all needed ad vantages in fixin g it in position along the jaw, as described, to accommodate different-sized teeth. The piece U, with its depending parts X, movable on the end of jaw B and fixed by set-screw W, affords all needed facilities for regulating their bearing on the saw.

In using this instrument the bolt S is first adjusted to permit sufficient play of the jaws after theinsertion of the saw. The gage-piece K is then placed in such a position from the end of the jaw as may be found necessary to allow the front part of the bolt S to extend beyond the face of the lugs Q, and thus have a bearing upon the tooth of the saw. After these preliminary arrangements the instrument is ready for use, the operation of which is similar to other tools of this'class.

Fig. 3 is a modified form of sliding piece and bolt of upper jaw, the sliding piece an ranged to DIOVG vertically for the purpose of adjusting the piece.

\Vhat I claim is 1. In a saw-set, the jaw A, having piece G on its end, the plate G, grooved at H, combined with the sliding gage-piece K, its lower ends forming lugs M, and the set-screw 0, whereby the plate K can be readily fixed in any position along the end of A, substantially as described.

2. In a sawset, the sliding gage K, having its ends bent to form lugs M, to clasp piece G on the outer end of jaw A, and the set-screws O and J, combined with thethreaded bolt S and regulating'nut T, substantially as and for the purposes set forth, whereby the gage and bolt can be regulated, as described. 7

In a saw-set, an adjust-able gage having arms X, and held in position by set-screw WV,

all as shown and described.

In testimony that I claim the foregoing I December, 1883, in the presence ofwitnesses.
