SAW-SET.
To all whom it may concern:
State of California, have'invented a new and Improved Saw-Set, of which the following is a specification.
My invention primarily has for, its object to provide a simple, inexpensive and eiiicient device adapted for being operated by one hand for setting aseries of teeth in opposite and directly over the longitudinal center of directions at each operation of the device.
Another object of my invention is to provide a device in which the setting dies or members are cooperatively so arranged that they will not dull, or otherwise injure, the
points of the teeth, while setting them and in which the connection'ofgthesetting lever and the die holding jaws is such that movement of the setting leverin .one direction opi crates to open the jaws to provide for conveniently receiving the saw between the die plates.
My invention in its complete make-up also guide or gage members for regulating the distance the saw teeth are to penetrate be tween the dies and for holding the toothed edge of the saw in true position throughout its length during the operation of setting.
My invention, consists in the peculiar'construction and novel arrangement of the several parts that constitute my invention, all of which will be hereinafter fully explained, specifically pointed out in the claims and illustrated in the accompanying drawing, in which: v
Figure 1 is a perspective View of my im proved sawset, the same being shown in an operative position. Fig. 2 is a top plan view thereof, parts being broken away to the more clearly illustratethe co-relation of the 7 points of the saw teethand the end guide enthe bottom jaw 1, is fixedly held on a bench or other'support by a clamp bolt 2, as shown. 3 designates the top jaw and the same, near one edge, has a pair of apertures Specification of Letters Patent.
I I i for receiving a pair of guide posts 5, pref- Be it knownthat I, J AMEs MILLER SMITH, residing, at WVengler, county of Shasta, and,
the setting dies 910, the reason for which will presently appear.
Each jaw has alongitudinal recess'1l12 for receiving'the setting dies or plates 910 which, in my construction, consist of two pieces of steel whose opposing or saw tooth engaging faces are so formed that a large number of teeth are set at one operation; in the drawing, the dies being shaped for lever, seven on one side and eight on the other side, they being also shaped for setting large or small teeth.
13' designates the operating lever, which terminates at the lower end in an eccentric head 14:, and it is so mounted on the fulcrum between the posts that when the said lever is swung to apply the setting dies, the forward edges, between which the saw blade is projected, close down upon each other first before the rear or die carrying portions are, clamped together. This feature of my. invention is important since the saw blade is securely clamped and held in proper position before the dies efi'ect their tooth setting operation.

bers which include slotted extensions 16-16 gaging the toothed edge of the saw relatively to the size of the teeth is provided, and the. said plates provide for regulating the amountof set to be given to the saw.
To provide for ,quicklya'nd conveniently lifting the upper jaw to receive the saw between the two jaws, one edge of the eccentric head is formed with a segmental shaped lateral flange 18, that travels over a headed 75 setting fifteen teeth at one stroke of the s stud 19 that extends up from the top jaw,
as is clearly shownin Fig. 4: from which it will bereadily noted that when swinging the lever backwardly (see arrow Fig. 3) the eccentric head tilts the blade clamping end of the upper'jaw away from the lower jaw. Among other advanta-gesmy device can a be quickly manipulated with one hand,
movement of the lever in one direction serv ingto-first clamp the saw in position and then apply thejsetting dies while the movement of the lever in the other direction opens up the jaws.
What-I claim is: a
'l." Ina saw set, a fixed projecting from said block a setting. die carried by saidblock to one' side of said standards,a movableblock loosely slidable on the standards and a diet on the movable block opposing the die on the fixed block, said standards having a fulcrum bearing projected in the plane ofvthe dies, and a cam lever mounted on said fulcrum to engage the movable block to firstcause said movable block to clamp the-saw blade against the fixed-block and upon further movement to cause said dies to set the saw teeth. 7
Copies of this patent may be obtained for av; cents each, by addressing block, standards 2. saw setting means'that comprises a fixedly held aw, an opposing, movable jaw,; I
guides for relatively holding the jaws in their opposing alinement, a setting die mounted on each jaw, acam lever so fulcrumed when moved in one direction to first cause the'movable jaw to clamp thefblade'} against the fixedly held jaw and upon further movement in the same direction to cause the setting dies to set the saw teeth.
3.. A saw setting device comprising a fixedly held jaw,j an opposing movable jaw,
standards for relatively holding the jaws in their opposing alinement, a a setting die 'mounted on each jaw, said" dies opposing each other, a lever devicefulcrumed on the standards" for moving the movablejaw and I die against the other jaw and die, when swungln one dliQGtlOIl, and connections between'the said lever and the movable -;jaw
