To all whom it may concern:
Be it known that I, LEONARD SHANE, of Hampton, in the county of Franklin and in the State of Iowa, have invented certain new and useful Improvements in Planes; and do hereby declare that the following is full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference thereon, making a part of this specification.
The nature of my invention consists in the use of a device which is secured to the end of a plane, for the purpose of canting the same, for planing beveled surfaces, as will be set forth.
ln the annexed drawings, Figure 1 is an end view of a plane with device attached, and Fig. 2 is a perspective of same. In the figures, A represents the end of a plane, to which is connected, by means of a set-screw, a slotted bar, B. To one end of this bar B is pivoted a triangular guide-plate, D; it is also connected to the bar B by means of a set-screw, i, which works through a slot, e, in said plate. The angle of the bar D can be changed on the end of the plane by means of the set-screw C, and the angle of the plate D can be changed on the bar B by means of its pivot and set-screw i. It will be seen that, by means of these two changes, the plane can be canted so that it will work upon irregular surfaces.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is —
The combination, with a plane, A, of the bar B, having the slot a, and the set-screw C, the triangular bar D, pivoted to the bar B, and having the curved slot e, and the adjusting-screw i, all substantially as and for the purposes set forth.
In testimony that I claim the foregoing, I have hereunto set my hand this 11th day of May, 1874.
LEONARD SHANE.
