Description

NTTED sTATEs PATENT onirica;
JESSE GILMAN, OF NASHUA, NEW HAMPSHIRE.
LATE-MACHINE.
Specification of Letters Patent No. 14,499, dated March 25, 1856.
To all whom t may concern:
Be it known that that I, Jnssn GILuAN, of Nashua, in the county of Hillsboro, and State of New Hampshire, have invented a new and useful Improvement in Machines for Sawing Laths, Clapboards, &c.; 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 which- Figure l, is a longitudinal vertical section of my improvement, (00,) (m), Fig. 2, showing the plane of section. Fig. 2, is a plane or top view of ditto, the reciprocating carriage or bed to which the stuff is attached being removed.
Similar letters of reference indicate corresponding points in the two figures.
My invention consists in the peculiar means employed for feeding the stuff to be sawed to the saw, and reversing the movement of the stuff as will be presently shown and described, whereby a perfectly automatic feed movement is obtained.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A, represents the framing ofthe machine of rectangular form and constructed in any proper manner to support the working parts. I
B, represents an arbor or shaft to which the saw, C, is attached, the arbor or shaft being. placed transversely on the framing, A.
D, represents a shaft which is placed in the framing, A, parallel with the saw shaft, B. On this shaft there are placed two cams, E, E, at a suitable distance apart, see Fig. 2; and F, is a friction roller which is fitted between the two cams, said roller being on the inner end of a lever, G, which is attached by a pivot, (a), to an arm, (Z9), on the framing. The outer end of the lever, G, is forked and is fitted over a clutch, H, on a shaft, I, which connects either of two pulleys, J, J, with the shaft, I, the pulleys being placed loosely on said shaft.
K, is a belt which passes around the pulley, J, and also around a pulley, L, on a shaft, M, in the lower part ofthe framing; and N, is a cross belt which passes around the pulley, J and a pulley, O, on the shaft, M. To one end of the shaft, M, a pulley, P,
is attached, having a belt, Q, passing around it, which belt also passes around a pulley, R, on one end of the saw shaft, B.
On the shaft, I, there is placed a pinion, S, which gears into a toothed wheel, T, on a shaft, U, ysaid shaft having a pulley, V, upon it, around which pulley a cord, (0); passes said cord also passing around a pulley, (d), and having both ends attached to a carriage, W, which works between suitable guides, (e), on the framing, A. The ends of the cord, (c), are attached to opposite ends of the carriage as shown clearly in Fig. l. On the upper part of the framing, A, and directly underneath the carria 'e, W, there are placed longitudinally two ro s, (f), (f), the ends of which are fitted in bearings, (g), the rods being allowed to slide in said bearings. To one of the rods, (f), there is attached a cord, (It), which passes around a pulley, X, on the shaft, D. The rod, (f), has an ear or projection, (z'), attached to it, through which ear or projection the rod, (f), passes said rod (f) having two pins, (j), passing through it, one at each side of the ear or projection,
Y, is a spiral spring which is attached to a crank pulley, (7c), `at one end of the shaft, D. f
Z, is a friction roller which is made to bear against the belt, Q, by means of a spiral spring, A', which is connected with a lever, B, at one end of a shaft, C, on which the friction roller, Z, is placed, said friction roller being on a crank on said shaft.
Operation: The stuff toI be sawed is secured upon the carriage, W, in any proper manner, and motion is given the saw arbor or shaft, B, in any proper manner; and if the clutch, H, is in gear with the pulley, J, on the shaft, I, the pulley, V, on the shaft, U will rotate in the direction indicated by the arrow, l, and the carriage will be moved by the cord (c), in the direction indicated by the arrow, 2, and the stuii:l will be fed to the saw, and when the carriage, W, arrives at a certain point a projection, ((L), underneath the carriage, W, will strike a pin, (b), on the rod, (f), and said rod will cause the rod, (f), to be moved and the cord, (k), will turn the pulley, X, and the cams, E, E, will also be turned, and in turnl ing will operate the lever, G, and throw the clutch, H, in gear with the pulley, J and owing to the cross-belt, N, the shaft, I will i be rotated in an opposite direction and a reverse movement will be given the carriage, WV, which when it reaches the eXtreme point of its backward movement will be again moved forward in consequence of the projection, (a), striking against the ear or projection, (i), which causes the lever, Gr, t0 throw the clutch, H, in gear with the pulley, J.
Thus it will be seen that a perfect automatic feed motion is obtained and by very simple means. The invention may be applied to sawing machines at a small cost,
and is not liable to get out of repair.
Having thus described my invention, what JESSE GILMAN.
