GAGE.

SPECIFICATION forming part of Letters Patent No. 438,029, dated October '7, 1890.

Application filed July 19, 1889- Serial No. 317,993. (No model.)

To all whom it may concern:

Be it known that 1, JOHN L. STRAHL, of Glouster, in the county of Athens and State of Ohio, have invented a new and Improved Gage, of which the following is a full, clear, and exact description.

The invention relates to gages for woodworking'machinery; and its object is to provide a new and improved gage, which is simple and durable inconstruction and can be readily ,adapted for grooving, gaining, crosscut-sawing, mitering, &c.

The invention consists ofi certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in theclaims.

- Reference is to behad to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan View of the improvement asappliedto a saw-table. Fig. 2 is an enlarged plan View of the improvement. Fig. 3 is a side elevation of the same. Fig. at is an end elevation of part of the improvement, and Fig. 5 is an enlarged section of the guideway for the slide inithe saw-table where woodtaps are used.

The improved gage A is provided with a slide .B, adapted to fit into a groove or guideway 0, formed in the saw-table D. The groove 0 is parallel with the saw and may be formed directly in the wood part of the saw-table, as shown in Fig. 1, or a cast-iron guideway O, as shown in Fig. 5, may be fitted into the sawtable. The top of the slide B is flush with the top of the saw-table.

On one side of the slide B are formed two or more recesses B, into which extend the bolts E, screwing into the slide B and locked in place by jam-nuts F. The heads of the bolts E press against one side of the guideway O, and as the said bolts are adjustable any wear of the slide can be easily taken up, so that the slide is always in a true position in the guideway. The opposite side of the slide Bis provided with metallic corner-pieces G, so as to reduce the wear to a minimum.

On top of the slide B is pivoted at H a graduated plate H, provided on one side with a flange H to which is secured an arm I, against which the work to be operated on The upper end of the bolt J is provided with a handle K for conveniently turning said bolt, so as to clamp the plate H in any desired position on the slide B.

A fixed pointer L is located in the top of the slide B, in the middle of the same, and indicates on the graduated segment H When the latter is in the position shown in Fig. 2, the flange H carrying the arm 1, stands, with the latter, at right angles to the slide B. When the bolt J is loosened, the plate H and the arm I can be turned so that the latter assumes any desired angle in relation to the slide B, the, degree of such angle being indicated by the pointer L on the graduated segment H A post N is erected on the slide B in front of the arm I. On the said post N is fulcrumed a lever 0, extending over onto the top of the arm vI and adapted to be lockedin place on the said arm bya nut-arm P, screwing on a screw Q, secured on the stop of the said arm I. k

On the lever O is held a block R by means of a staple R, secured to the said block and fitting over the lever 0. I When the nut-arm 1 I P is disengaged from the lever O, the latter can be swung upward, and then thewood to be operated on is placed on top of the slide B and pressed against the arm I. The lever O is then moved down, so that the fiat bottom of the block R rests-on topof the work to be operated upon, by'ineans of the nut-arm P being moved over the said lever O, asis plainly shown in Figs. 1 and 2. The woodto be operated on is thus held in place on the slide B, and when the latter is moved toward the saw or cutters the wood is cut at an angle indicated by the pointer L on the graduated segment H Thus when the wood, as 10, is in place, as shown in the drawings, Fig. 1, and the slide B is moved onto the saw or the cutters, the wood is cut at right angles to its length. When the graduated plate H is turned, as before described, so that the arm I stands at an angle to the slide B, the end of the wood is cut off at the angle indicated by the pointer L on the graduated plate H On the front end of the arm I is formed a suitable groove, into which fits a thin rod S, secured in place on the said arm I by screws or other suitable means, and having its ends projecting beyond the ends ofthe arm. On the outer end of this arm S is held a plate T by means of a bolt U, screwing in the said arm S and passing through a slot T, formed in the said plate T. The outer end of the bolt U screws into a nut U, held on the plate T, so that when the bolt U is turned the said plate T is securely locked in place on the rod S. WVhen the bolt U is slackened, the plate '1 may be moved forward and backward on the rod or arm S to any desired position and then locked in place by the said bolt. This rod Sserves for laying out the work for the measuring, crosscut-sawing, gaining, &c.

Byprojecting the ends of the rods S beyond the ends of the gage-arm the movable stop-plate T may be used on either or on both ends of the said rod. The one shown in the drawings serves to measure the distance between gains in the window-frames, &c.' If such a stop-plate is put on the :other end of the rod S, it serves to measure the distance to first gain.

The fulcrum of the lever O in the post N is preferably made adjustable, so that the said lever can be raised or lowered to accommodate work of different heights.

Having thus fully described my invention, I claim-as new and desire to secure by Letters Patent- 1. In a gage, the combination, with a slide mounted to slide in a guideway in the saw-ta ble or other wood-workin g machine, of a grad-. uated plate pivoted on the top of thesaid slide, and a lever fulcrumed on the said slide and adapted to be locked in place on the said graduated plate, substantially as shown and described.

2. In a gage, the combination, with a slide adapted to support the work to be operated on, of a lever fulcrumed on top of the said slide and serving to lock the work in place, and a graduated guide-plate pivoted on the top of the said slide and against which the work rests, substantially as shown and described.

3. In a'gage, the combination, with a slide adapted to support the work to be operated on, of alever fulcrumed on top of the said slide and serving to lock the work in place, a graduated guide-plate pivoted on the top of the said slide and against which the work rests, and a fixed pointer held on the said slide and indicating on the said graduated plate, substantially as shown and described.
