CHAIR-SEAT-SURFACING MACHINE.V
. SPECIFICATION forming part of Letters Patent No. 682,820, dated September 17, 1901.
Application Bled May 23 1901.
To all whom t may concern:
Be it known that LCHARLES A. STARK, a oitii zen of the United States, residing at Union City, in the county of Erie and Stateof Pennsylvania, have invented certain new and useful Improvements in Chair-Seat-Surfacing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.
My invention relates to improvements in chair-seat-surfacing machines, and has for its objectV the construction of mechanism whereby the surface of a chair-seat can be hollowed ont and surfaced at one operation. To accomplish this result, I construct a machine having two rotary cutter-cylinders of suitable contours mounted in a yoke or frame operating upon tracks secured to a sliding carriage to which the chair-seat to be surfaced is secured, these tracks being provided with depressions, so that the cutter-.cylinders are raised and lowered during the traverse of the chair-seat thereunder, so as to produce the shaped surface therein desired. These 'and other features of myinvention are hereinafter fully set forth and described, and illustrated in the accompanying drawings, in which#- Figure I is a side view in elevation of a chair-seat-surfacing machine embodying my invention. Fig. 2 is a top or plan view of the same. Fig. 3 is a front end view in elevation of the same. Fig. Atisa top or plan view of the sliding carriage of my machine andthe tracks and chair-seat-clam ping mechanism thereon. Fig. 6 shows a section of the tracks on the .two sides of the sliding carriage, showing the 5o shafts C D, provided with pulleys c o and d d. Belts E E connect the pulleys b b on Serial No. 61,533. (No model.)
the shaf t B with the pulleys c d on the shafts C I), by means whereof they are driven by the shaft B. These features may be varied as de- `of rotary cutter-cylinders H' and I', and on the ends of the shafts H and I, I secure pulleys Il2 and I2, from which belts J and J eX- tend to the pulleys c' and d on the shafts C and D. The cutter-cylinder H is provided with double curved blades h, and the cuttercylinder I is provided with curved blades t', as illustratedin Figs. 1 and 2. of the blades h and t of these cutter-cylinh ders can, however, be varied according to the shape or shapes of chair-seat surfaces desired. From the ends of the arms F and G, below the bearings f and g therein, arms K and L extend downward and are provided with rollers 7c and I in the lower ends thereof, as and for the purpose hereinafter set forth. In the top of the frame A, I make longitudinal ways ot d, and on these ways I mount a longitudinally-moving carriage M, (see Fig. 3,) preferably provided with a rack m on its under side, with which a pinion m on a transverse shaft M intermeshes, this shaft M being provided with a crank m2 for operating it, by means of which mechanism the sliding carriage can be moved back and forth as desired.
On the top of the sliding carriage M, I provide a convenient clamping mechanism N N nn for clamping a chair-seat 'upon the sliding carriage M. On each side of the carriage M, I secure two tracks O and P. On theinside tracks O O the rollers k vk on the arms K K travel, and on the outside tracks P P the rollers IZ fl on the, arms L L travel, and in each of the tracks P P, I make a curved depression p, and in each of the tracks O O, I make a curved depression o, the shapes of which curves and their relation to each other being clearly shown in Figs. l, 2, 4I, and 5. rIhese curves and their relation to each other The shapes roo may, however, be varied according to the shape of the depression desired to be made in the chair-seat being surfaced.
In operation a chair-seat is clamped upon the carriage M, and as it is first moved under the cutter-cylinders II and I' the rollers 7c travel down into the depressions o in the tracks O, which operates to bring the cylinder H' into contact with the chair-seat, so as to surface the front portion thereof, and the further travel of the carriage causes the rollers Z to travel down into the depressionsp in the tracks P, which operates to bring the cylinder I into contact with the chair-seat being surfaced, so as to surface the rear portion thereof.
I have thus described and shown a convenient mechanism for utilizing my invention; but I do not desire to limit myself to the exact construction and arrangement of the parts, as many modifications can be made therein without departing from the spirit of my invention.
Therefore what I claim as new, and desire to secure by Letters Patent of the United States, is-
1. The combination in a chair-seat-surfacing machine, of a frame, a sliding carriage operating in ways upon said frame, two tracks on each side ofsaid carriage having differentshaped depressions therein, two cutter-cylinders mounted in bearings the bearings of one cylinder resting on one track on each side of the carriage, and the bearings of the other y cylinder resting upon the others ofthe tracks j on each side of the carriage, substantially as and for the purpose set forth.
2. The combination in a chair-seat-surfacing machine of a frame, two cutter-cylinders of different shapes mounted on said frame so as to be vertically movable, a sliding carriage on said frame, two tracks on each side of said Carriage having different-shaped depressions in the tops thereof, supports on the cylinderbearings of each cylinder adapted to be engaged by one pair of said tracks as they travel under said supports, substantially as and for the purpose set forth.
3. The combination in a chair-seat-surfacing machine, of a frame, a pair of arms pivoted at each end of said frame, a cutter-cylinder of one shape mounted in the inner ends of one pair of said arms, and a cutter-cylinder of another shape mounted on the inner ends of the other pair of said arms, a carriage operating under said cylinders upon ways on said frame, two tracks of different shape on each side of said carriage, supports under the bearings of one cylinder resting upon the outside tracks on each side of said carriage, and supports under the other cylinder resting upon the inside tracks on each side of said carriage, substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
CHARLES A. STARK.
