IMPROVEMENT IN PLANE-GUIDE.

The Schedule referred to in these'L'etters Patent and making part of the Same.

Y @rence beinghad to the accompanying drawing, and

to the letters of reference marked thereon, and bciu'g apart of this specilicatiolnin which- Figure 1 is an elevation of the front end of 1n y iniproi'ed plane and guide; and

-Figure 2 is a longitudinal section of a part 'of the plane above the joints.

Like letters indicate like parts in each figure.

The nature of this invention relates to the construction of a guide-attachment to carpenters planes, and consists in a novel and peculiar construct-ion of the 'guide,`and method of attaching the same to au ordinary plane, so that the edge of aboard may be join-ted with perfect truth to a right angle with the side of the board, or to any bevel. i

In the drawing- A represents the body of an ordinary plane, and

B, my guide,.provided, at its upper edge, with two halves of a loose butt, d, with its pin engaging, with au eye-holt, C, two of which are screwed into the lower face of the plane, in line with the outer edge of the plane-iron.

A catch-spring, c, is secured in a recess at the rear of each eye-bolt, in such a manner that, when the butt-pins arehinged in the eye-bolts, the former cannot be withdrawn and disengaged from the latter, until the springs are depressed; but one spring is re quired to hold the guide in place, although two are preferable.

VVD is a circular segment secured to the front end of the guide, passing through a guide, D', secured in the f front end of the plane,and provided wit-h aclampf.

screw, d. This arrangement enables the workman to adjust and sec-ure the guide -to any desired angle with the plane, so that the edge of a board may be jointed with perfect truth to the angle set.` A'

When not required the guide is detached, and the eye-bolts and spring remored.

I am aware of the invention of -William-H. Blye, for which Let-ters Patent of the United, States were granted to him on the 10th of April,1849, and dis claim the same. v

NVhat I claim aslny invention, and desire to secure by Letters Patent, is-

The plane-guide D', provided with the clamp-screw d, in combination with the segment D, in connection with the plane A, provided with the guide B, halfbntts a, eye-bolts O, and catch-'springs C, when the several parts areconstructed and arranged as described and shown, and for the purpose setforth.
