EDWINS. JACKSON, vOF BETHEL. lVERMONTI Letters Patent No. 108,147, dated October 11, 1870.
IMPRQVEMENT IN MACHINES FCR MANUFACTURING CHAIR-SEATS.
The Schedule referred to in these Lettera Patent and malnng part of the lame.
To all whom it may concern Be it known that I, EDWIN S. JACKSON, of Bethel, in the county of Windsor and State ot' Vermont, have. invented a new and valuable Improvementin Machines for Manufacturing Chairs; and I dohereby declare that the following is a full, clear and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawing is a top View of iny invention.
Figure 2 is a central vertical section of the same. f
Figure 3 represents a face view of the convex plane. My invention relates to means for hollowing and polishing the seats of chairs, and consists in the construction and novel arrangement of convex cutters and polishing heads, designed to perform the desired operation in a rapid and satisfactory manner;
The letter A designates a strong framework of Wood or other suitable material, provided with a'stout transverse beam, B, to which the holding or receivingblocks .O G are secured.
I) D represent. rotating shafts, having keyed or otherwise fastened thereon the pulleys E E, for-the Iapplication of power.
F designates the. convex plane or rotating cutterhead, provided with the curved bits a a, secured there in in such a mannner as to permit the passage of the shavings, &c., through the head, so that they will pass oli' between the armslib, which support it in rear.
G designates the convex polisher, covered with a suitable polishing substance, and adapted to render smooth the hollow yformed by the operation of the Y convex plane. p The operating heads are pressed up'to the work by means of the treadles L L operating the clank-levers h h, provided with forked ends, designed to embrace each shaft in rear of the collar k. At the same time, the heads are subject to the action of the springs z z attached to lthe ends f the shafts, and serving to draw them to the rear, in order to permit ot' the introduction of fresh work;
rlhe operator stands facing the head, and, keeping.
the receivers charged by means of the treadles, he
can hollow and polish a great number of `chair-bottoms -in a rapid manner and without much fatigue.
What I claim as my invention, and desire to secure The arrangement of the rotating hollower G with bits a, and the polisher F, the lever It L, stop k, spring z, and holders G, substantially as shown and described.
In testimony that I claim the above, I have hereunto subscribed my name inl thepresence of two wit- HBSSES.
EDWIN S. JACKSON. Witnesses:
T. A. OHADWICK, D. GRAVES.
