MIIION O. G-ODDING, OF MONROVIA, CALIFORNIA.

BEVEL-GAG E.

Application filed July 6, 1888.

To aZZ whom it may concern.-

Be it known that ]',";\I1LoN demand, of Monrovia, in the county of Los Angeles and State of California, have invented a new and useful. Improvement in Bevel-Gages, 01' which the following .is a specification.

This invention contemplates certain improvements in bevel-gages for bench-planes, mill-saw tables, and planing-maehine tables, having for its object to vary the angle of the cut or bevel, the same being (fletermineijl in inches or degrees, thus obtaining any desired angle of cut or bevel, as occasion may require and as is practiced especially in carpentry and joinery.

To these ends the nature of the invention consists of a hinged plate or guide the supporting-plate oi. which is adapted for application or attachment to the utensil with which it is to be used, while said guide or plate is provided with curved or segmental guide-rods and a graduated segment, which guide -rods pass through and are adjustably held in posts or standards applied to the clamp-plates or directly to the supporting-plate, and with which graduated segment registers a pointer or index also applied to said sup portin g-plate,

substantially as hereinafter more fully set.

forth and claimed.

In the accompanying drawings, Fig-u re 1 is a side elevation of my invention, and Fig. is a sectional elevation on the line a: a; of Fig. 1. Fig. is a horizontal section on the line 11/ y of Fig. l, certain portions being broken away.

In carrying out my invention I make use of two plates, A A, one being prelt'erably wider than the other. The narrower plate, A, is riveted or fastened to cross- )late-like bars a a, which are hinged at their inner ends to the wider plate, 1 The outer ends of the platelike bars a a are carried inward, or formed with inwardly-project-i n g lateral ii an ges a a, through which pass tlunnb-screws I) I). These screws carry or connect with and et't'ect the adjustment of clamp-plates c c, which are adapted to be moved along the plate-like bars a a, and are guided in their movement by means of screw-like studs or pins (Z (I, screwed into the clan1p-plates and passing through slots 6 e in the plate-like bars a a.

plate A with inwardly-projecting flanges ff, which unite with the elamp-plates c in formin the clamps proper.

In order to permit of the compact arrangement or disposition of the parts, the flanges ff are on t away or recessed intermediately of their ends to receive the hinged eye portions on the plate A.

Applied to the plate A at its outer or rear side are a graduated segmental plate, B, and two segmental rods, C O, the rods being se cured one near each outer corner edge of said plate, while the graduated segmental plate or are is arranged intermediately of said rodsit may be near one of said rods. The plate 13 is marked off into a scale of degrees, as also of inches.

Posts or sup mrts I) D are planted in the plate-like bars a a near their inner ends, and are provided with apertures a near their outer ends, through which pass the rods C C, and with thtnnlrscrews b b, which are inserted into the said ends thereof and engage with said rods. This arrangement effects the holding of the plate A at the required angle ol adjustment. The plate A is also provided with a knob, c, for its convenient manipulation or adjustmcmt.

E is a pointer or index, which is fixed to the plate A at its rear side and slightly bifurcated a suitable distance inward from its outer end to receive the graihiated segmental plate B at its inner edge, the taperin or pointed portion or end of the pointer or index registering with the scale or graduations upon the plate I In. operation it will be seen, with the gage applied to a bench-plane, for instance, that by properly moving the plate A, by grasping its knob, to the required angle, the thumbscrews 7) I) having previously been loosened, the plane, with. its bit, is disposed with relation to the work so as to get the required bevel.

in planing or cutting the material; also, the angle oi adjustment of the plate A is obtainable in degrees, as is necessary in making a cut, especially in preparing material to co11- form to the pitch of roofs, &c.

In applying the instrument for use in connection with a mill-saw table or a planingmachine table the plate carrying the clamps is removed, and in its place is designed to be substituted a plate having holes for bolts which effect the screwing of the instrument in place.

From the foregoing it will be seen that this invention is adapted to aid in producing any required bevel or a cut of any angle of inclination in an expeditious manner, as is required especially in carpentry and joinery work.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The bevel-gage comprising the hingedtogether plates, one being provided with a pointer or index and adapted for application to a planing-tool, while the other is provided with a graduated segmental plate and segmental rods passed through apertured posts applied to the aforesaid plate and provided with thumb-screws engaging said rods, substantially as set forth.

flanges and a pointer or index, while the other plate is provided with segmental rods and a graduated segmental plate, said rods being adjustably held in posts which are secured to the said plate-like bars, substantially as specified.
