LOG-TURNER.

EPECIFICATI-ON forming part of Letters Fatent No. 293,316, dated February 12,1884.

Application filed December 13, 1893.

zen of the United States, residing at Zoar Station, in the county of Tuscarawas and State of Ohio, have invented a new and useful Log- Turner, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to log turners for saw-mills; and it has for its object to provide a simple and efficient device which will readily turn logs by steam-power, and which may be attached to any saw-mill.

It also has for its object to provide a device which will operate, with a small amount of power, to turn the logs as fast as required; and a further object of my invention provides means whereby the operating mechanism may be thrown into engagement at will and out again atthe proper moment.

With these and other objects in view the said invention consists in certain details of construction and combination of parts, as hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my improved log-turner in position on the saw-mill. Fig. 2 is a ver-. tical longitudinal sectional view of the log turner. Fig. 3 is'a detail transverse sectional View taken through the operating-shaft. Fig.

4 is a similar view, but taken at right angles thereto, through the operating-lever which throws or brings the devices into engagement.

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

Referring to the drawings, A designates the base-frame of the log-turner, from which extend two uprights, B B, having braces or supports 0 G,'and transverse connecting-strips I). A lifting-lever, E, is fulcrumed between the uprights at their top, and carries at one end a pivoted lifting-hook, F, suspended from a cord, G, and has a cord or line, H, evtending up from its other end, said line working over a pulley, I, connected to the upper end of a /\-shaped frame, J, and'having a weight, K, secured to its end, and serving by its gravity to aid in lowering the hook end of the lifting-lever. The A-shaped frame J is journaled at its lower end in a transverse beam, L, secured to the base A, and is adapted to (No model.)

connecting the said frame to the uprights B, said rods being jointed near their middle, to allow the slight forward movement of the frame.

N designates the log-carriage, of the usual construction, and upon which the log 0 is placed, said carriage having secured to its other enda frame, P, having a rotary operating-shaft, Q, journaled therein. A pulley, R,

loose belt or rope, S, with another pulley, T, sliding freely over a rod, U, secured to the sides of the frame P. A drum, V, is formed integral with the pulley T, and slides loosely over the rod U in a similar manner, an annular shoulder, WV, limiting the movement of the drum. 7

X designates a cross-bar, secured to the frame P at one end, and having a hanger, Y, fitted to its other end, said hanger carrying apulley, a, at its lower end, andpivoted in an arm, Z, attached to one side of a handle or lever, A journaled in the frame P. A hooked rod, 13,

opening, b, in the hanger, to hold and brace the latter in true vertical line. A cord or rope, O is connected to the drum V, and passes outward, through the framel and below the log- A. After passing through said pulley D the rope extends 'upward through a pulley, E journaled in a block, F depending from the under side of lifting-lever E, and then downward through a pulley, G secured to base A, the end of said rope being secured to the lower extremity of the pulley-block F.

The operation of my invention will be read ily understood from the foregoing description, taken in connection with the annexed draw ings. When the hook end of the lifting-lever is .drawn down to enable the hook thereon to be engaged in the log, the hand-lever A has simply to be operated to cause the pulley ato draw the loose belt S tight, when the operation of the rotary shaft Q will, by means of pulleys R T, cause the rope O to wind upon the drum V. The said rope as it winds upon the revolving drum will of course draw down the power end of the lifting-lever and raise the hook end, which thereby turns the log in the manner well known in the art. This movemove freely forward and backward, rods M- carriage, to a pulley, D, journaled in the base 7 is mounted on this shaft, and connects by a is attached to the arm Z, and engages'with an ment of the lifting-lever has caused the rope J forward, so that when the limit of the rope O has been reached the hook end of the lifting-lever may be drawn down, the weighted cord H acting to assist in lowering the hook to its normal position.

It will be seen that the action of turning the log is positive and the device. for throwing the operating mechanism into operation is simple and effective, the tension of the belt S being increased, so that the operation of the rotary shaft will turn the drum and pulley to wind the rope O in the manner stated. The rope or band S in its normal state is too loose to transmit'motion from the rotary shaft to the pulley and drum, and consequently it requires some such tension device as I have devised to form a connection for the parts mentioned. It will be apparent that I do not limit myself to the particular device shown, as other means may be .employed to effect a like purpose.

The rotary operating-shaft is connected to the saw-mill and receives motion therefrom, so that the turning of the logs is effected wholly by steam-power; and by reason of the connection'with the power end of lifting-lever a greater power is obtained than would be otherwise.

Having described my invention, I claim 1. In a log-turner, the lifting-lever carrying a hook at one end, incombination with the rotary operating-shaft, a pulley and drum formed integral with each other and mounted loosely upon a bar, a loosely-fitting belt connecting the pulley and shaft, devices for increasing the tension of the belt, anduneans for connecting the drum with the power end of the lifting-lever, as set forth.

2. Inalog-turner,thelifting-lever fulcrumed in suitable uprights and provided at one end with devices for raising the log, in combination with means for operating said lever, a pivoted frame havinga jointed connection with the uprights, and a weighted line connecting the power end of the lever with the said frame, as set forth.

3. In alog-turner,thelifting-leverfulcrumed in uprights B, and provided at one end with devices for grasping the log, in combination with means for operating said lever, a pivoted frame working in the rear of the lever and provided with jointed rods secured to uprights B, which permit the free forward movement of the frame, and .a weighted line secured to the power end of the lever and passing through a pulley secured to the frame, as set forth.

4. In alog-turner,thelifting-leverfulcrumed in suitable uprights and provided at one end with means for grasping the log, in combina tion with a rope connectingwith the power end of the lever, a drum upon which said rope is wound, a rotary operating-shaft, a l0osely-fitting belt connecting the shaft and drum, and devices for increasing the tension of the belt at will, as and for the purpose set forth.

6. I11 a log-turner, the combination, with the rotary operating-shaft, of a bar arranged parallel with the same, a pulley and drum formed integral and mounted upon the bar, a loose belt connecting the shaft with the pulley, and a hand-lever provided with an arm carrying a pulley arranged to increase the tension at will, as set forth. g

7. In a log-turner, the combination, with the rotary-operating shaft, of a bar arranged parallel with the same, a pulley and drum formed integral and mounted upon the bar, a loose belt connecting the rotary shaft and pulley, a handlever, AF, provided with an arm,

Z, a hanger, Y, secured to the arm and carrying a pulley, a, a cross-bar, X, supporting the hanger, anda brace-rod connecting the hanger and arm, as set forth.

8. In a log-turner, the uprights B, provided with suitable brace-bars, and a lifting-lever fulcrumed between the uprights, a hook, F, attached to one end of the lever, a weighted line secured to the other end, a rope, O pulleys G D E", a drum upon which the rope is wound, and means for operating the drum, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of witnesses.
