`CHARLES F. PACKARD, OF GREENWICH, CONNECTICUT.

siiwING-MAGHINE.

l `Specification of Letters Patent No. 11,257, dated July `11, 1854.

To all whom t may concern.'

Be it known that I, CHARLES F. PACKARD, of Greenwich, in the county of Fairfield and State of Connecticut, have invented a. new

showing t-he inner side of the frame opposite to the `inner side shown in Fig. 2. view shows the device by which the reciprocating motion is giventhe carria-geon which the log is secured. In both Figs. 2, and 3, the

` plan of sectionzis through `the center of the frame.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to anew and` improved sawing machine for sawing laths, pickets, ete., direct from the log, and consists in the `employment oruse of avertical saw, or a vertical reciprocating saw, and a series of horizontal circular saws, the horizontal saws being placed `on one shaft at a `suitable distance apart',.sai`d shaft being attached to a vibrating frame operated in a peculiar manner, as will be hereafter shown, so that the horizontal` saws will be thrown outward from the carriage and log, when the carriage and log are moved in one direc tion, and thrown in toward thecarriage and log when the carriage and log aremoved ini the opposite direction.

When the horizontal saws arethrown in toward the I log, they cut into the log the distance the width of the laths, pickets, or other articleto be sawed from the log are intended to be, and when the horizontal saws are thrown from `the log up'on the return motion of the carriage, the vertical circular saw cuts the laths, pickets, or other article from the log.

To enable others skilled in the art to make and use my invention, I will proceed to de-` scribe its construction and operation.

on its upper part, a carriage, B, shown in This all of theiigures. Underneath the carriage,

I3, there is a rack, C, shown in Fig. 3.

D, is a circular saw `attached to ahorizontal shaft, E, which shaft runs in suitable bearings, (a), on a small frame,fF, attached upon it, a belt, passing around the drivingpulley, G, and around a pulley or drum, (c), on the saw shaft, E. vH, Fig. 1, is a shaft, also hung in the frame, F, and parallel with the shaft, E. `On the shaft,

H, there is a drum, (d), against which the belt, (Z2), bears sufficiently hard to cause the shaft, to rotate. I

I, Fig. l, is a shaft placed in front of the small frame, F, and having a pulley,J, on its bute-rend, and a pinion, K, ongits inner end. A belt, (e), passesaround the pulley, J, and around the drum, (c), on the shaft, E. The pinion, K, `gears'into a toothed wheel, L, which is hung at one `end of a shaft, M, in `the frame, A, the shaft, M, extending entirely across the frame, A, as shown `in Fig. l. The inner end of the shaft, M, is fitted in a lever, N,-having its fulcrumat (f), `thelever being attached to the inner side of the frame, A, see Fig. 3. On the inner end of the shaft, M, there is a pinion, see Figs. l, and 3, which, when the end of the lever," N, in which the shaft, M, ,rests is raised, gears into the rack, C, underneath the carriage, and when the end of `the lever, N, is depressed, the pinion, (g), gears into a pinion,V it), attachedto the inner-side of the frame, A, see dotted linesin Fig. 3, the pinion, (71,), gears into a pinion, (i), which pinion, (i), gears into a pinion, (j), communicating with the rack, G.

O, Figs. l, and 3, is a lever, having its fulcrum at (la),` and attached to the inner Vside of the frame, A, shown clearly in Fig.

the outerv end of thelever, O, `there is an inclined plane,

(a), more particularly shown in Fig. 3.` ,i

P, are a series of horizontal circular saws, placed at suit-able distances apart `upon a shaft, Q, which has its bearings in a vibrating frame, R, shown in Fig. l. The saws,

P, are driven by means of a belt, (o), Fig. l, which passes around the shaft, Q, and around the drum, (d), on the shaft, H.

S, Figs. l, and 2, is a rod which is attached to the vibrating frame, R, and toa lever, T, on the inner side of the frame, A. The lever, T, has its ulcrum at (Z9), as shown in Fig. 2, and by dotted lines in Fig. 1. l

U, Fig. l, is a movable or sliding bed o n the carriage,B,see Fig. l. This bed, U, 1s provided withvclamps, (g), (g), at one end, between which the log, V, to be sawed is secured. The log, V, is represented by dotted lines in Fig. l. The bed, U, is provided with racks, (r), (1^), the upper parts of which are shown in Fig. l, and pinions, (s), (s), on a shaft, W, gear into said racks. On the outer end of the shaft, W, there is a ratchet wheel, X, into which a pawl, (t) attached to a movable frame, Y, catches.

Operation: The log, V, to be sawed 1s sel cured between theclamps, (g), (g), on the bed, U, motion being communicated to the shaft, E, the circular saw, D, is made to rotate by means of the belt, (Z9), passing around the pulley, G, and drum, (c). Motion is given the carriage, B, by means of the pinion, K, gearing into the toothed wheel, L. The pinion, (g), gears either into the rack, C, underneath the carriage, B, or into the pinion, (h), see Fig. 3. Suppose the pinion,' (g), to be depressed on gearing into the pinion, (h), the carriage will then be moved in the direction indicated by the arrow l, shown in all the igures, and the circular horizontal saws will cut in the log, V, the required depth, as the carriage, B, and log, V, is moved along. The saws, P, are held in the proper position by means of a spring, Z, Figs. l and 2, which bears againstthe lever, T, and keeps the saws at the proper point, so as to cut the requisite depth into the log. When the carriage, B,

yhasmoved the length Aof the log in the direction of arrow l, a stump, (u) attached by a pivot to the carriage, acts against an inclined plane, (w), at the outer end of the lever, T, and forces the saws, P, outward from the lo-g, the vibrating frame, R, being retained in an outward position by means of a spring catch, which passes over Vthe inner end of the lever, T, shown clearly in Fig. l. A stump also acts at the same time upon the inclined plane, (n), on the lever, O, and causes the catch, (m), to raise the outer end of the lever, N,and throw the pinion, (g), in gear with the rack, C, underneath the carriage, B, which, in consequence, moves in a reverse direction, see arrow 2, and the vertical saw, D, cuts off the laths, pickets, or other articles from the log, V, it being understood that the horizontal saws, P, determine the width of the article sawed by the depth they enter the log. Y The log, V, is properly fed toward the saws, P, at every vibration or stroke of the carriage, B, by means of the pawl, (t), op-

erating the ratchet, X, said pawl being moved by means of a stump, (c), acting against an inclined plane, (af), attached to the frame, A, as shownv in Fig. l. v

I do not claim the vertical saw and hori- Zontal saws, operating as herein shown, irrespective of the peculiar arrangement and mechanism, whereby the motion is given the vibrating frame.

What I claim therefore, and desire to secure by Letters Patent, is

The combination of a vertical circular saw D, or a vertical reciprocating saw, and the horizontal circular saws P, when said saws are constructed, arranged and operated
