Description
UNITED STATES i PATENT oEEIoE.
JOHN J. CURTIS, OF EAST BOSTON, MASSACHUSETTS.
SCROLL-SAWIN G MACHINE.
Specification of Letters Patent No. 17,425, dated June 2, 1857.
To all whom it may concern:
Be it known that I, JOHN J. CURTIS, of East Boston, in the county of Suffolk and State of Massachusetts, have invented a new and Improved ScrolLSawing Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in whichd A Figures 1 and 2, are vertical sections of my improvement; the planes of sections crossing each other at ring angles, and passing through the center of the machine in both figures. Fig. 3, is a detached plan or top view of the feeding device.
' Similar letters of reference indicate corresponding parts in the several figures.
My invention consists in the employment or use of a rotating bed and feeding device, arranged as will be hereinafter fully shown and described, whereby the feeding device is operated automatically, and the stuff always fed properly to the saw, irrespective of the position in which the stuff may be turned or moved by the will of the operator during the prosecution of the work.
To enable those Skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A, represents a rectangular frame, having within it a smaller rectangular frame B, both frames resting upon the same base. On the upper part of the smaller frame B, friction rollers (a) are placed; and a circular bed or table C rests on these rollers. At the center of the upper part of the frame B, a collar C1 is secured; and the upper end of this collar fits in a circular recess (b) in the underside of the bed or table C; said collar forming the center on which the bed or table rotates; the friction rollers (a) supporting the bed or table near its periphery, see Figs. 1 and 2.
Through the center of the bed or table a circular opening D is made, and a saw E passes through said opening, the lower end of the saw being attached to a block or head F, which works on two vertical guide rods (c) (c). To the block or head F a pitman G is attached; said pitman being connected to a crank wheel H, on a driving shaft I. The upper end of the saw E is attached to a block or head J, which is tted in a dovetail groove (el) made in o-ne side of a pendent bar K, attached to the upper part of the frame A.
To the upper end of the block or head J, a cord or chain (e) is attached, and the upper end of this cord or'chain (e) is attached to a pulley K1, at (f). To each side of the pulley K1, a smaller pulley (g) is attached, and to each pulley (g) a cord or chain (71.) is attached. The upper ends of these cords or chains (h) (7L) are attached to one strip or leaf (i) of a spring L. The upper strip or leaf (j) of the spring L has a cord or chain (la) attached to it; and this cord or chain passes over a pulley (Z) on the upper part of the frame A; the lower end of said cord or chain being attached to a winch M, secured to one side of the pendent bar K.
The spring L is constructed by placing the two flat steel strips or leaves (i) (j) together, one over the other, and securing one end of said leaves to the frame A; a
slide (m) is placed on the two leaves.
In the back part of the pendent bar K, the same side to which the winch M is attached, a rackbar N is placed, and allowed to slide freely up and down in a'groove therein. A pinion gears into the rack N; said pinion being on a shaft (0) which is fitted in bearings attached tothe pendent. One end of the shaft (o) has a handwheel O, attached. To the lower end of the rack-bar N, a` roller (p) is attached.
4The driving shaft I has a lbevel wheel (g) secured on it; and the wheel (g) gears into a corresponding wheel (r) at the lower end of a shaft (s) which has a screw (S1) on its upper end. The screw (s1) gears into a worm wheel (t) on a shaft l?, which has a pinion (u) on its inner end, and the pinion (u) gears into a pinion (ai) attached to a wheel Q. This wheel Q has a corrugated periphery, and its edge projects a trifle above the surface of the bed or table; the said wheel Q, being within the opening D.
The teeth of the saw E are precisely at the center of the bed or table. The upper end of the shaft (s) has its bearing in a lever (e), and a handle (el) is attached to this lever, as is plainly shown in Fig. 3.
The operation is as follows: The stuff to be sawed (shown by dotted lines) is placed upon the bed or table C, and its end placed between the two rollers (p), Q; the roller (79) being made to bear upon the stuff with the requisite degree of pressure by turning the Wheel yO. Motion is given to the shaft I, in any proper manner; and a reciprocating motion is communicated to the saW from said shaft by means of the crank-Wheel H, and pitman Gr. The saw is properly strained by the spring L, and the strength of the spring may be graduated as `desired by adjusting the slide (m) on the or table C is turned by the operator, and the stuE changed in position relatively to the saw, With the greatest facility; and as the cutting edge of the saw is at the eenter of the table, the saT is not subjected to any undue strain or pressure, and the 'ma chine may be controlled by a single operator. The Wheel Q may be stopped or put in motion at any time by operating the handle (el).
Having thus described the nature and operation of my invention, What I claim as new, and desire to secure bylrLetters-Patent, is:
l. The rotating bed or table C, arranged substantially as shown, and in such a relation to the saw, thatl the bed or table may rotate around the cutting edge of the saw as a center, for the purpose set forth.
2. I claim the feeding Wheel Q, arranged and operated substantially as shown, when used in connection With a rotating bed or table C, for the purpose specified.
JOHN J. CURTIS.
