i I Application filed January 23, 1894. Serial o. 497,809. (No model.)

T0 all whom it may concern: l

Be it known that I, WILLIAM H. MILLER, a citizen of theUnited States of America, residing at Spring Creek, in the county of Rockingham and State of Virginia,have invented certain new and useful Improvements in Saw- Sets, of which the following is a specification,

reference being had therein to theaccompanying drawings. w

This invention Yrelates to certain new and useful improvementsin saw sets of which the following is such aclear, full and exact description as will enable others skilled in the art to which same.

The object of my invention is to provide a saw set adapted for use on all forms of saws and on which will work effectively on circular, band, cross-cut, and hand saws, which', owing to their Vvarying widths cannot be set'except by an adjustable instrument or one especially designed for the work. i

A further object of my invention is to pro- Aduce a simple and vcomparatively inexpensive construction which Will be strong and durable as well as efticient and sat-isfactor'y in use;

furthermore, the invention consists in the novel manner of Operating the plunger or hammer and in communicating motion thereto from the handle or lever.

Finally the invention resides in the various novel details of construction, arrangement and combinations of parts to be hereinafter more fully described and specifioally pointed out in the claim.- i A; i

In describing the invention in detail reference is had to the accompanying drawings forming part of this specification, wherein like numerals indicate correspondin g parts in both the views, in which- Figure 1, is a sideview of my improved sawset. Fig; 2, is a similar detail view partly in section.

In the drawings, 1, denotes the body-portion of the device with an extending arm la, while 2, indicates a pivotally seoured arm,which with the arm 1a, 'forms the handle; the arm 1a carries a shaft 3, having a V-shaped longitudinal groove forming a shoulder 4, adapted to snugly fit and operate against the wall 5, of a transverse recess 6, of the spring pressed plunger 7; said plunger being slidingly mounted it appertains to make and use the in a bearing 8, of the, body-portion and provided with a pin 9, near its outward extremity which acts as a stop for the coil spring surrounding the'plunger and seated .against the end of the bearing. w

' The body-portion on its underneath side is cut away to form a transverse slot 10,' forming a shouldcr 11, to which is attached an an- *Vil 12,'beveled at 12a that swaged teeth may be voperated on without injury; directly above the said slot on the body-portion is arranged a yoke 13, attached b'y means of a Vbinding screw 14, passing through the face thereof. The yoke is also provided with an aperture 15, on its top face for the reception of the adjusting screw 16. The yoke is further provided with outwardly extending fianges 17.

The body portion has 'right angular exten- .sion 18, terminating in a lug 19, adapted to receive' the screw-threaded bolt 20, of the handle 21, the nut 22, is fixed on the screwthreaded bolt and serves to gage or regulate the bolt 20.

After the'saw is seeured in a vise in the well known manner, the anvil is placed against the side of a tooth and a pressure brought to bear on the pivotal arm which is brought to the position shown in dotted lines Fig. 1, thus partially rotating the shaft and communicating motion to the plunger, which is forced against the opposite side of the saw tooth, on which a firm hold is obtained. To give the saw tooth the desired set, the screw threaded bolt 20 is set to abut against the side of the saw at the angle required and the nut22, brought flush against the side of the lug; and by means of the handles 2, 1a and 21, the power is applied inthe well'known manner, and when the handles are released the arms and plunger are 'i returned to their normal positions. The yoke regulates the depth of the bite to be taken on the saw and its adj ustment is easily and y quickly accomplished.

It will be particularly noted that various changes may be made in the details of construction without materially departing from the general idea involved.

Having fully described `my invention, what I claim as new, and desire to secure by Letters Patent, isi Ioo In a saw set, the combination with the body portion provided with an extending arm and a slot to receive the saw teeth, of the yoke above said slot, the arm oarrying a pivotal shaft with aV-shaped recess forming a shoulder, the spring pressed plunger actuated by said pivotal shaft, a right angular 111g extend- -ng from the body porLion and provided With a threaded aperture, and a, screw threaded handle adapted to enter the aperture of the 111g and extend ontwardly ab right angles WILLIAM H. MILLER.
