TO ALL WHOM IT MAY CONGERNz..

Beit known that I, STINSNHAGAMAN, of Weissport, in the county Carbon, und State of Pennsylvania,

have invented anew and improved Machine for Planing and Fih-ishing the Framesvof School-Sintes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and usethe same, reference being had to the accompanying drawings, forming partfof this specification, in'which- ,t

Figure-1 represents a side elevation of myrimproved schoolslateframe planing and finishingfmachinc.A

This invention relates to 'a machine'for planing and nishing the frames of school-slates in an expeditious ,and handsome manner, undicontains a horizontal circularA planer, (of iron, or any other suitable material,) in which three (more or less) planeirons are held, and so arranged (when i'n motion) as to strike the whole surface of one side of thesIate-frame at the same time when it is brought in contact with the planer. Then the slate `,is turned over, andthe other side of the frame is finished in the saine manner.

This inventionconsists, first, in the manner-.of holding and applying the slate (or the frame) to the under surface of the horizontal planer, one small vertical shaft sliding in suitable bearings, ontopof which is fastened a frame or table, containing a cavity, in which the slate is held. The shaft is raised or slid in its bearings hy a trendle or lever, causing the slate (or the frame) to-'comein contact with the planer. There is an' a.djustable sleeve and slide on` and connected with this shaft, that serves as a gauge, to prevent the planer from cutting more 'olf the slateframe than to produce a smooth and even surface. This shaft is prevented from revolving by somesuitable iixture, against which the frame or table rests. -Y

' This invention consists, second,- in hanging a circular planer on the-lower extremity o i'ha vertical shaft,

'and screwed fast, that it may be easily detached and another attached, as each will require to be a certain diameter, to suwit the 'size of slate inished. l u Y A represents a rectangular or other frame, made of wood 5r other suitable material, of suiicient strength to support and hold the working parts of this machine. v

B vis an -unprightshaft, having its bearings in theframeA, upon which is a pulley, C, over which a belt l passes, to impart motion tothe machine.

' D is a circular` planer that iuishesv the slates.A Y

E is a shaft, also having its bearings in the frame A, on top of which is a Harige, F, that supports the frame or table G, that holds the slate, H, (in redink.)

Qn this shaft is also a loose sleeve, z', with a set-screw,j, and a nut, lc, underneath, that, when the set-screw is loosened, the sleeve z' muy be very accurately adjusted, as it is tc serve as a gauge to regulate the thickness of the slateframes. Y

Above this sleeve z' is a slide, Z, (in"rcd'ink,) against the thick end of which the sleeve t' rests when, the first side of the slate-frame is planed, and against the' thinner end (the slide being shifted) yafter the slate is turned l over, and the other side being finished.'

By pressing` upon the lever or .treadle M, theshaft E is elevated, causing'the frame of theA slate H to come in contact with the under surface of the planer D.

The blocks N N, fastened on the frame A, prevent the frame or table G from revolving, but not from moving up and down.

Having thus described my invention, what I claim as' new, and desire to secure by Letters Patent; s; The loose sleeve t', setscrew j, nut lc, and slide l, in combination with the shaft E and treadle M, operating substantially as described, and for the purpose specified.

`STINSON HAGAMAN.
