IMPROVEMENT IN TO'OL FOR IMAKING-` SYPLINTS.

TheSchedule referredto in lthese Letters Patent making part of the same.

To lwhom it may concerne l Be it known that I, CHARLES F. STEWART, of Gornnna,in the county ot' Shiawasseaand State of Michigan, have invented a new and useful Improvement in vTool for Cutting Window-Curtain Splints; and I do declare that the following is a true and accurate description thereof, reference' being had to the accom,- panying drawings and to the letters of reference marked thereon, and being a part of this specification, in which- Figure l is a vertical'longitudinal ysectional view of my improved plane; Figure 2 is an eleva-tion ot its rear end; and Figure 3 is a front elevation of the plane-iron. Like letters indicate like parts in each figure.

The nature of this invention relates to animprovement in the construction of a plane for cutting thin splints from the edge of a board, which, splints are woven into curtains or shades.

It consists in the employment of a combination and arrangement ofits several parts, inthe progress of the cutter through the timber; also, in the peculiar formation ot' the stock of the plane with a recess formed in its body by the insertion ot' a tongue near the bottom of its rabbet or groove, through which the splint passes.V

By means of the arrangement described, the splint is raised but very little above the horizontalplane ot' the board, and is prevented from being made shaky on the under side, as is the case in other planes where the splint is discharged from a throat at the top of the stock, splints cut with this tool being perfectly smooth on both sides.

1n the drawingsf- A represents the stock yot my plane, provided with the usual handle a.

In the bottom of the stock is formed arabbet or groove, B, ofthe width of the thickness of the board from which the splints are cut or shaved.

To the rear o f the plane-iron this rabbet is deeper than in front, and by the insertion of the tongue O a horizontal throat or passage, c, is formed.

The under side of the 4tongue is on a lower plane than the bottom of the` groove in front of the planeiron, the difference being the thickness of the splint.

l) is the plane-iron, having a lip, d, turned tol nearly a right angle with its body and ground to a cutting edge. p

In the body of the iron is cut a recess or throat, E, extending down tothe back of theV lip` d, through which the splint passes into the throat c of the plane.

The planeiron is secured in the throat or slot blot the plane by a wedge, F, in the usual manner, and is set so as to allow the point of its lip to take a shaving of the required thickness.

A board of the proper length is steamed or soaked to soften and toughen it. It is then secured edge up in a vise. The operator then shaves oii` the splints in the usual manner; each splint is 'lifted but, the thickness 'of the lip d above the edge of the board, its end passes through the slot E of the Aplane-iron into the passage c of the stock, whence the splintis discharged when the cut is completed.

It will clearly be seen that the splint cannot shake or check on its under side when out with this tool, as it is not bent upward to split it oft in advance of the cutter, as when cut with planes of other patterns, nor is it liable to break from the same cause. Each splint is smoothly shaved on both sides.

W hat I claim as Ilnyinventiou and desire to secure by Letters Patent, is

In combination with the plane-iron el (l E, the arrangement ot the passage e, the tongue C, and the groove B, when constructed and operating as and for the purposes aforesaid.

CHARLES F. STEWART.
