Specification of Letters Patent No. 10,905, dated May 16, 1854.

To aZZ whom t may concern Be it known that I, HIRAM FRIsEE, of Olmstead, inthe county of` Cuyahoga and State of Ohio, have invented new and useful j Improvements in the Construction of Lath- Machines; and I do hereby declare that. the following is a full and exact description thereof, reference being had to the annexed drawings, making part of this specification.` The nature of my invention consists 1n hanging the log upon centers ina carriage l the log, as it traverses over the saws; also in the combination of devices for adjusting the log to the saws, so that lath, or strips of any desired thickness or width may be cut fronr the log; and also, in revolving the log by the action of a ratchet, the thickness of a lath,? immediately on each strip or lath being cnt from the log. i j

To enable `others skilled in the art, to,y make and use my invention, I will proceed to describe its construction and operation. j

Figure l, is a plan Xiew of the machine; Fig. 2, a side elevation, Fig. 3, a transverse section Aof the frame, without the carriage, in thefdirect-ion of the red lines X X, of Fig.

riage without the frame, in the direction of the lines X X Fig. 1. The other view willV be referred to in description.

Like let-ters refer to like parts in the dif ferent views.

A, represents the log, hung in the carriage B B, by the centers C C, upon which it revolves, and which centers are se'cured to the slides C C, Figs. 1, ande; these centers re tain the log in place, but do not sustain the whole weight of;it, as the log rests on the j rollers D D. The rollers revolve upon the each time it passes its lengt-h over the saws F F, in either direction longitudinally, by the ratchet G, Figs. 1 and 4, which is con-` nected at the lower end, to the stay lever H,

by a joint. The stay lever is hung upon l journals near its center, to the under sideof the carriage.

As the carriage passes over either of the cam blocks, 'I I, in the direction of the arrows, it brings the stay lever `in Contact with them alternately, and by the `inclined planes of the cam blocks, over which slides the stay lever, the end to which the weight J is hung, is raised, and the other end, to which the ratchetI is attached, `is depressed; thereby revolving the log, as t-he ratchet teeth are forced into it by the spring G, and its own inclination. As soon as the stay lever passes the cam blocks, by the action of the weight, a reverse movement is given to the stay lever, which relieves the ratchet teeth from the log, and causes the point H of the lever, as seen in Fig.A 4, to be forced into it; which secures the log in place while traversing over the saws.

The movements for rotating the log, take place directly after it leaves thesaws. It matters not in which direction the ylog may be traversing, the result is the saine, butas the carriage returns in a reverse direction of the arrows, the stay lever againpassesWover` i the cam blocks, but as they are hung upon a center pin, they turn upon it by the lever,

until the stay lever passes over it, then turns back to its place, and is prevented from `turningonly in the desired direct-ion, by the stay pins I I", which are inserted inthe side of the frame.` The logis prevented from turning' more than the thickness of a lath, by the roller D3, Figs. 3, 4, and 5, against Y which the shoulder or scaf, in thelog rests,`

as it traverses. These rollers are supported i by the arms D4 which are secured to the frame, d, are keys tor adjusting the arms to the log. The traversing .movement is lgiven to the carriage B B, by the rack and pinion K and K, the pinion 1being keyed to thesame shaft as that onwhichthe clutch loose pulleys L, and L', are keyed. These clutch loose pulleys belt out to the, tight pulleys M M. l l i On the other end of the" same shaft `to `.which the tight pulleys are attached, is the driving pulley N, on` the outside of the frame. `By t-his `arrangement of belt-s and pulleys, any movement given -to the driving pulley N, causes a corresponding movement to be conveyed to thefpinion K, which traversesthe carriage, by means of the `rack K.

The forward` and backward traverse of ioc ' cuts the lath 0E horizontally, and the saw.

1 F, vertically, `as seen in Figs. 3 and 4. l

from the clutch P, to the clutch P', which,

,the pulleys clutch and unclutch, by the Y over the saws, a lath is cut off.

yfast as cut from the log.

vwhich the carriage traverses on the ways Vshaft W, which is driven by belting from .by which a motion is conveyed to the pulley the carriage is obtained by cross belting, as j follows: The driving wheel N, turning in the direction of the arrow, causes the carriage to move from the position it now has in Figs. l and 2, and by the action of the pin O, the shifter O is moved, thereby the pulleys L and L are shifted on the shaft, from the pin P, to P, which causes the carriage to move to I, then by the action of the pin O, 'on the shifter, the direction of the carriage will be again reversed by the cross belt, on connecting the pulley L, to M, by which it will traverse to I, then again the reaction takes place as before described. This reverse traversing of the carriage from I, to I, and from I to I, is produced by the belts on the pulleys L and L, and M and M Fig. 1 the belt o-n the pulley L and M, being a cross belt, and the other straight.

In combination with the clutch and pins P and P, the pulley is moved by the shifter by the cross belt moves the carriage to I, leaving the pulley L to run loose; when the pulleys are again shifted from P to P, the pulley L clutches, as seen in Fig. l, leaving the .pulley L to run loose, thus alternately action of the shifter, which gives the reverse traverse of the carriage, on the frame over the saws. Each time the log traverses The lath being cut oft from the log, drop upon onelof the aprons or conveyers, Q Q, according tothe position of the log over each apron or conveyer. These conveyers revolve upon the rollers R R, which are turned by the belt S, from the pulley S', Figs. 2 and 3. By this arrangement the lath are conveyed to the front of the machine, for bundling, as

e On the front of the machine is the indeX plate T, for counting the lath; this machine is-operated by the pall and ratchet T and T, Fig. 1. The ratchet is on the opposite end of the shaft, to which the pointer is, and is worked by the pall T, attached to the carriage.

' Cn the under side of the carriage are wheels, as seen at U U, Figs. 2 and 4f, upon U U', which ways are secured to the frame VV. Inside of the frame are the circular saws F and F. The saw F, is secured to the same shaft as the driving pulley N, as seena't W, Fig. 3, and the saw F is on the the shaft W, to the shaft X, by the belt-X',

V, by the crossbelt X, which is on the same shaft as the saw F, which shaft has a point and step at-the bottom. The saw F `of sawing.

The arms DL D4, slide inthe frame, and are secured in place by the keys d d. These sliding or adjustable arms, in combination with the rollers D D, upon which the log rests, and the slides D D, provided withV the adjusting screws E E, are the means employed for the Vpurpose of adjusting the log to the saws, so that lath or strips, of any thickness o-r width, may be cut from the log.

The adjusting screws will raise or lower the log in a vertical direction from or to, the log, according to the required width of the lath or strip; and the'arms D4 D4, adjust. the log horizontally to the saws, according to the required thickness of the strips or lath.

Lath which are sawed from the log, are superior in all cases, to lath cut from the log, by means of knives, in the latter case,

the lath are invariably checked or split by the action of the knives, in severing them from the log, and when the log is knotty,

portion of the lath are worthless by their` being so split and broken up, by the wrenching of the knives and log.

When saws are used the lath are of uniform thickness and width, free' from checks,

as the saws will cut through the log withy out its starting or diverging from the saws, or the saws from the log, which is found not to be the case when knives are used.

Vihat I claim as my improvement, and desire to secure by Letters Patent, is-

1. The combination of the movable cam blocks I I, stay lever H, ratchet dog G, and weight J, for the purpose of successively turning and gripping the log, in the following-'manner, the ratchet dog rotates the log the thickness of a lath as the stay leverl passes over the movable cam blocks I I on the instant the stay lever passes the movable cam block, the stay lever is reversed by the action of the weight J causing the log to be gripped and held stationary by the point of the lever at I-I during the process The act of turning and gripping the log takes place alternately as the carriage traverses backward and forward in the direction of the arrows.

2. I claim the combination of the adjustable rollers D, D, and D3, D3 the slides D D and the adjusting screwsv E E with the slides C C as hereinbefore described, and for the purpose set forth.
