SAW-SET.

SPECIFICATION forming part Of Letters Patent No. 519,366, dated May 8, 1894.

4 Application filed August 12, 1893. Serial No. 483,007. (No model.)

To @ZZ whom it may concern:

Be it known that we, CHARLES WHI'rUs and JOHN W. WILKS, citizens of the United States, residing at Chester, in the county of Chester and State of South Carolina, have invented certain new and useful Improvements in Saw-Sets; and we do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the` art to which it appertains to make and use the same.

Our invention is a new saw set and consists in the novel construction and arrangement of its parts. r

The object of our invention is to enable th operator to set all saws used ata workbench from the smallest to the largest, and in fine saws to set as many as three or more teeth at a stroke, and `with larger saws two or more teeth and with still larger saws one tooth, and where the teeth of thesaws are exceedingly iine we` may remove the die from the point of the plunger and place a washer behind the anvil thus bringing the anvil in reach of the plunger and `set `one tooth at a time of the most delicate saw. p

In the accompanying drawings: Figure `1,is

. aside view of our invention partly in section.

Fig. 2, is a top plan view. Fig. 3, is a perspective view of the combination guide and gage. Fig. 4f, is a perspective View of the anvil. Fig. 5, is a perspective View of the washer. Figs. 6 and 7, areperspective views of dies usedin connection with our invention.

Our invention is described as follows:

A, represents the body of the invention, a, the handle integral with the body, b, the lever handle pivoted tothe body, a', the nose piece, a?, and a3, the throats and 0.4, the mouth. The

lever handle b, is pivoted between the bifur-` cated projection b, of the body A, and has a shoulder b, for moving the plunger c, forward. Said shoulder is provided with a friction roller c3, which operates against the rear end of the plunger. Said plunger operates through the throats a2, and a3, inl the body of the invention and is made to stand back against the roller c3, inthe shoulder b2, by means of a spiral spring c. The said throats 0,2, and a3, are circular and the plunger that operates therein is cylindrical and fits in said throats. The front end of said plunger is Vsmaller than its body leaving a shoulder c4,

plunger and its face against the shoulder of t the plunger. The die may be turned either edge up (see Figs. 6 and 7). The dieblocks (Figs. 6 and 7) are all the same size and are kept from turning on the point of the plunger by means ofthe guides d, on the upper and front part of the combination guide and sliding gage D. The said combination guide and sliding gage \D, is provided with a vertical longitudinal slot cl, through which the threaded portion of the thumb screw d2, passes and screws into a threaded opening in the lower side of the body.

In the nose of the body is a recess e, for the anvil e', to rest in, which is provided with an incline e2, to determine, in combination with combination guide and sliding gage D g the set of the saw. And in the nose of the body A, is a vertical slot e3, through which the t threaded portion of the thumb screw e4, passes and screws into a threaded opening in the anvil e. The object of the last named arrangement is for the purpose of enabling the operator to move the anvil up or down to determine the length of the set.

When we wish to set a fine saw we use the dief, which is provided on one edge with three teeth 1, 2, 3-which enable us to set three teeth of a saw at one stroke. This edge of the die will set a saw with from -thirteen to fifteen teeth to the inch.

. When we wish to set a coarser saw we turn the other edge of the die up, which is provided with two teeth 4, 5-and set two teeth of a saw at one stroke, and is adapted to set a saw having fromeight to eleven teeth to the inch.

Die g, is provided with one tooth, and is adapted to set y larger and coarser saws; sets one tooth at a stroke and is, therefore, not confined to saws with any given distances between the teeth but may set any work bench sawno matter how far the teeth may be apart.

We may use as manydifferent dies as we see proper and they may be cut to set the teeth of any saw.

IOO

when we use it as a saw set, and in the face.

l of the anvil We make an opening 5,provided with an escape opening e6.

We are aware that a saw set has heretofore` been invented having a body, handles, nose, anvil, plunger, and gage; said gage however is not providedwith our guides d,for.keep.ing the die in proper position, and the plunger, has its front end shaped to impinge against a saw tooth and can set only one tooth at a stroke, and has a portion of `its surface liat-` l tened its entire length,l and the :throats 1 throughwhichitpasses yhasfa portion Hat'- tened to-correspond withthe plunger to'keep. it from-turning. Said invention has. no dies,y
