SAW-GAG E.

SPECIFICATION forming part of Letters Patent No. 415,023, dated November 12, 1889.

Application filed May 4, 1889. $erial No. 309,668. (No model.)

To all whom it may concern; Be it known that I, GEORGE M. GLEN- DINEN, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, have invented new and useful Improvements in Saw-Gages, of which the following is a specification.

My invention relates to saw gages or guides for regulating the depth of the kerf, its object being to provide a removable and adjustable gage adapted to be set to various positions on the saw and applicable to both crosscut and ordinary hand saws.

To this end myinvention consists in a gage construction, as herein set forth, as an independent attachment to a saw, to be applied to any saw and adjusted and used as occasion may require.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a side view of an ordinary handsaw with my improved gage in position; Fig. 2, a side View of a crosscut-saw With my improved gage applied thereto; Fig. 3, a view of the gage detached; Fig. 4, a side view of the holding-clamp or rider detached; and Fig. 5, a sectional view taken across the saw-blade, the clamp or rider, and the holding-braces.

Referring now to the drawings, A B designate an ordinary carpenters ha ndsaw and a crosscutsaw, respectively; 0, the gage proper; D D holding-clamps arranged as riders to fit the back and sides of the sawblade, and E E F l pivotal slotted braces connecting the clamps and the gage. These constitute the general features of the apparatus, which are more particularly described as follows:

The gage proper 0 consists of a flat bar of metal, which, in the preferred form of the invention, has one straight edge adapted to a handsaw and one curved edge adapted to a crosscut-saw. To this are pivoted two upright braces E E and two intervening diagonal braces F W, the two latter being engaged by the same pivot 19 midway between the pivots p p of the upright braces. All of these braces are longitudinally slotted, as shown, and are preferably made of sheet-steel.

The clamp-blocks are recessed to fit over the back and sides of the saw, as indicated most clearly in Fig. 5, each provided with a set-screw Ct through one of the walls of the recess to bear against the saw and hold the block firmly in position. A similar set-screw b is threaded through the body of the clampblock above therecess, and is carried through the slots of the upright and its correspond- I ing diagonal brace, and by its enlarged head holds them firmly against the face of the clamp-block in any position in which they may be set. The clamp-blocks being once set in position, the gage C may be adjusted to any desired position in relation to the cutting-edge of the saw by loosening the setscrews 1) h, and firmly retained in such position by again tightening the set-screws.

In applying the device to a crosscut-saw the gage-bar O is inverted in position, so as to bring the curved edge of the gage into proper relations with the cutting-edge of the saw. The change from the adjustment of .parts as shown in Fig. l is effected by detaching the set-screw b and reversing the position of the braces and reconnecting them with the clamp-blocks.

The device, being wholly detached from the saw, is folded into the position shown in Fig. 3 to be put away when out of use.

It will be obvious that without removing the clamp-blocks, Fig. 1, the gage may be set more toward the point or the heel of the saw, as desired, or adjusted to any depth of kerf, and firmly held in such new position by tightening the set-screws. It will also be observed that the diagonal braces serve to resist any longitudinal displacement of the gage in either direction, while the vertical braces directly resist any vertical displacement, and that both oo-operate to maintain the gage in its desired position. Moreover, the gage is applicable to any saw and requires no punching or mutilation of the saw-blade for its attachment, but may be applied by any one in a very brief time and without skill.

One of the diagonal braces may be wholly omitted and the advantages of my invention obtained in'a measurable degree; but I prefer to use both.

I claim as my invention and desire to secure by Letters Patent of the United States- 1. An adjustable and removable gage for saws, embodying recessed clamp-blocks adapted to ride on the back of the saw, a gagebar adapted to lie alongside of the saw in adjusted relation to the cutting-edge, and slotted braces connecting the clamp-blocks and gagebar both vertically and diagonally and adjustable upon the clamp-blocks by setsorews, all arranged substantially as set forth.

2. The combination of the clamp-blocks D to D gage-bar C, and braces E F E F and set-screw 12, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
