UNITED STATES PATENT OFFICE.
REUBEN HAYNES, OF OBERLIN, OHIO.
MACHINE FOR CUTTING LATI-IS.
Specicaton of Letters Patent No. 21,675, dated October 5, 1858` T0 all 'whom t m ay concern:
Be it known lthat I, REUBEN HAYNEs, of Oberlin, in the county of Lorain and State of Ohio, have invented a new and useful Improvement in Lath-Machines; and I do hereby declare the following to be a full and complete description thereof, reference being had to the accompanying drawings, in which- Figure l is a side elevation of my improved lath machine; Fig. 2 a view of the side opposite that shown in Fig. l; Fig. 3 a plan view, and Fig. 4 an end elevation.
Like letters denote like parts in the severa-l views.
The general form of the frame work, is shown at A, and the knife stock B, Figs. l and 2, is connected to hangers A', A', which form a part of the frame work, by four parallel links O, O, two on each side, of the knife stock, as seen in Figs. l and 3', at the points O' of the connection of the links with the knife stock and hangers, are formed wrist or pin joints which give the knife a combined lateral and vertical motion.
The knife stock is attached to the crank or driving shaft, D, by the connecting rod E, which rod is connected by a suitable joint to the knife block and by a strap joint to the crank on the driving shaft which is provided with proper bearings or boxes at F, and to which is attached a pulley or gear for the purpose of driving the machine.
Upon the driving shaft is keyed the bevel gear G, Figs. 3 and 4l, which meshes into the intermediate gear G', and by which the bevel gear H, is operated. In the wheel H is secured a wrist which works in the slot I, in the arm or lever I Fig. 4; the opposite end of this arm is hung loosely upon the shaft J, to which the ratchet wheel K, is keyed. The pawl L, rotates the ratchet wheel, by the action of the arm I', as the wheel H, rotates, which gives a vibrator lnotion to the arm.
The pawl L is for the purpose of preventing back action of the log, when a throw has been given to it by the pawl L.
The slot I in the arm I is the section of a circle, and of the same radius as that described by the wrist in the slot when the wrist is in motion with the wheel I-I. By this means when the wrist is in a vertical line to the axis of rotation of the wheel H, the lever I remains at rest while the wrist passes through the section of a circle, in t-he slot I. As soon as the wrist has passed this section of a circle, it directly commences to depress the lever; thus, by the action of the wrist, the lever I' is raised, and lowered for the purpose of rotating the log by means of the pawl and ratchet and spur wheels M, which wheels press into the log. As the lever I, is raised by the wrist, the log receives a turn or throw sufficient for the thickness of a lath, by the intervention of the pawl and ratchet, and thespur wheels which are keyed to the same shaft J, as the ratchet wheel K.
As soon as the throw has been given to the log, itremains at rest by the wrist passing through the circular section of the slot, and while the wrist is passing through this circular sect-ion, and the log is at rest, the knives are cutting off a lath, and as soon as the lath is cutv ofl", the lever again begins to work, the spur wheels are pressed into the log, by the weight N, which is hung to a bar above, and from which depend two arms O, O, which rest on t-he shaft- J, from the bar extend two other arms O', O', Figs. 2, 3, which are connected to the top plate of the frame work by a pin joint so as to allow the weight to rise and fall according to the size of the log. The horizont-al knife P, is operated by a crank on the lower end of the shaft Q, to which crank is attached the connecting rod R, Figs. l and 2, this connecting rod is attached to the knife stock P', by a pin or wrist joint: the knife stock P', slides in ways or bearings at each end of the knife stock as seen at S, S, Fig. 3 which gives the knife a forward movement which with the reciprocating movement by the crank and connecting rod gives the knife a lateral forward or oblique movement, similar to the vertical knife. Both knives move conjointly, the upper knife cutting off the lath vertically and the lower knife horizontally. It is by the rotation of the log itself, that it is continually being raised up to the knives. In each end of the log is driven a dog or center one of which receives the square mandrel or gudgeon a, Figs. l and 2, and the other dog or center, receives the center screw b, it is by means of this center screw that the log is retained in place and loosened from the machine. The log turns upon the center screw, the screw remaining stationary in the head block, but the mandrel (L, turns with the log, and carries with the bevel gear c, this bevel gear is provided with a sleeve which sleeve revolves in the headblock, and through which sleeve passes the mandrel a. As the log is turned in the manner before described, the gear, C, moves also by means of the mandrel. The gear c meshes into the gear d which gear is keyed to the revolving sliding shaft e, the
spur gear f, is also keyed to the same shaft e, and meshes into the two pinions g, g, which pinions are keyed to the screws h, it, Fig. 4, these screws work in nuts at z', z', and the upper ends form centers or pivots for the head block j. The head block rests upon Ythese pivots,'and slide up and down in gains in the posts 7c 7c. There is a headblock, like that seen at j, at the other end of the log, and which slides up and down in gains in the posts 7c 70. The screw b passes through this headblock. The whole weight of the log and the headblocks rests upon the screws 71, L, and two more corresponding thereto, under the'headblock, at the other end of the log, and which are operated by gearing like y those at d, 7", g, g.
From each headblock extend brackets l, l, which are fastened to the headblocks, these brackets receive the upper ends of the sliding shafts e, m, in such manner as to allow each shaft to be suspended therefrom, and to revolve, consequentlythe gears c, d, f, a, and sliding shafts m, and e, move up and down with the log uniformly, the sliding shafts m, and e, slide in the eye of thel gears 0, and p. In the eye of each gain is a feather key, which fits into a corresponding slot in each shaft the slot and key cause the shafts and gears 0 and p, to `revolve together and at the same time allows the shafts to slide up and down through the eyes of the gears. By the revolving of the log, a movement is conveyed to the shaft 1', by the intervention of the gears 0,cl, g, o, and s, the gear s, being keyed to the -shaft r, and meshes into the gear 0. At the other end of the shaft r, is keyed the gear t, which meshes into the gear u, on the shaft: m. As
the gearing at each end of the machine are.
of a corresponding size, it follows that each end of the log will be raised and lowered equally. TheW gearing for raising and lowering the log, are alike at each end of the machine, eXcepting the gears c, and d, and the motion is conveyed from the driving side to the other, by the connecting shaft 1', and its gears. On the upper and lower sides of the gears 0, and p, are shoulders which act as REUBEN HAYNES.
