LOG-TURNER.

SPECIFICATION forming part of Letters Patent No. 362,826, dated May 10, 1887.

Application filed January 24, 1887. Serial No. 225,411. (No model.)

To @ZZ whom it may concern.-

Be it known that we, HENRY MURRY FER- RIs, a citizen of the United States, and VIL- LIAM GALLON, a subject of the Queen of Great 5 Britain, both residents of Village Mills, in the county of Hardin and State of Texas, have invented certain new and useful Improvements in Log-Turners, and we do hereby declare that the following is a full, clear, and exact descripto tion of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- I5 ,Figure l is a perspective view of our improved log-turner, having a portion of the frame broken away. Fig. 2 is a central vertical sectional view showing the log being turned;

' and Figs. 3, et, and 5 are detail views of the 2o wedge-beam, log-catcher, and throwing-bar- In sawing logs into lumber the log is rst squared, which is done by sawing one or more slabs from its opposite sides. To do this requires that the log` be turned so as to present these sides or faces consecutively to the saw, which is a very laborious work unless it be done by power; but in the use of power devices the face of the timber is often cut or torn by the teeth of the device, which of course 3o damages the lumber to that extent, and-if the log be turned s'o as to fall upon the carriage the jar or pounding from such aheavy weight is apt to damage or break the carriage, and where the log is tnriied against the kneesthat is, by being turned so as to roll toward themthe loose bark and trash are ground up on the liead-block instead of being thrown off out of the way.

This invention relates to that class of log- 40 turners which is operated by power, and has for its object to provide a device that will be quick and positive in its operation, and which will avoid the above objections; and it consists in the improved construction and combination of parts, as will be hereinafter more fully set forth.

Referring tothe accompanying drawings, in which the same letters of reference indicate corresponding parts in all the figures, A represents a portion of the mill-frame, the saw and driving meehanisinnot being shown, as they are of the ordinary construction and form no part otl the invention. An ordinary carriage, B, is moved back and forth in front of this frame upon an ordinary track, G. Sliding vertically upon the front posts, D D, of the frame A are two upright log-catchers, E E, the upper end of each of which is beveled or inclined toward the carriage, as shown at F, and the lower portion is provided with the 6o shoulder G, formed by cutting away the rear portion of the lower end ofthe ulirights. Each of the posts D D is provided upon its rear side, near the bottom, witha notch, II, ot the saine depth as the eut-away portion of the log-catcher E. The shoulders of the log-catchers, and also the lower shoulder of each of the notches H, can be provided with f riction-rollers I I, if desired. Iivotally secured to one side of each of these log-catchers is a loading- 7o lever, J, the upper end of which projects slightly above the upper end of the log-ca tcher and the lower end extends below the shoulders G. By bending these levers, as shown, the middle portion can be secured to the body of the catchers and the upper end be back even with the rear side of the catchers at the top and nearly back even with them at the bottom. Secured within the notches II is a wedge-beam, K, which slides back and 8J forth upon the friction-rollers I. The Vinner portion of the shoulders at the bottom of each of these notches can be cut deep enough to permit this wcdge-beain to be kept in place by the cuter or higher portion; or the beam S5 can be kept in place by means of a turn-but ton or keeper secured upon the side of the posts. At cach end of this beam are two wedge-shaped projections, the ones on the top L L engaging with the friction-rollers in the 9o shoulders of the log-catchers, and the ones upon the side M M engaging with the lower ends ofthe loading-levers J. The top portions of the wedges L L are fiat, as shown at N N,

and their points are forward of the points ot' 95 the side wedges, so that the catchers E E are raised to their full height before thelower ends ef the loading-levers J are moved by the side wedges, the flat portion of the top wedges keeping them raised while the loading-levers roo are operating. This beam can be operated by means of a friction-pulley and chain, or steampower, or other convenient mechanism, and is kept from moving too far in either direction by means of suitable stops, which engage with the posts D D.

Directly beneath the carriage B is a frame, O, one end of which is pivotally secured in posts B B, which support the outer rail of the track, and the other end rests upon the intermediate portion of the wedge-beam K. The free end of this frame is operated or lifted by means of an inclined pawl, Q, the upper end of which is pivoted to a support, It, upon the beam K, and its lower end rests upon the top of the beam. Upon the top of this frame O is secured a cross-beam, S, having holes near its ends. Within these holes loosely fit the reduced ends of the arms of a throwing-bar, T, Vthe upper portions of which arms slide in guides upon the sides of the ties of the track, and the upper portion of the bar is parallel With the track and can be made long enough to extend any distance in front of the frame.

If desired, the lower ends of these arms can be secured to the ends of the cross-beam S by means of pivot-pins upon the ends of the beam passing through holes in the lower ends of the arms; or the frame can be made of such a shape as rectangular, for instance, and the lower ends of the arms be-secured directly to the frame without the cross-beam, the object being to cause the top of the bar to be raised whenever thel pawl Q, is forced under the free end of the frame.

Secured to the carriage, at about midway between the head-blocks, are two parallel vertical plates or bars, U U, between which, at one end, is pivotally secured a trip, V, consisting of a piece of metal bent or folded at its middle, and forming a slot or recess, W; or it can be formed of a solid piece of metal and be proby the throwing-bar T.

vided with such a slot or recess. Near the iniddle of this trip, within the slot W, is pivoted the upper end of a tripping-bar, X, the lower end of which moves just above and is operated The upperl end of this tripping-bar may be inclined and provided with teeth, as shown at Y, if desired, which engage with the lower side of the log and prevent it from slipping whilebeing turned. The lower portion of this tripping-bar can be cut away, as shown in dotted lines atZ; or the carriage-frame can be cut away to permit of the motion of the tripping-bar toward the side of the frame, caused by its upper end moving in the arc of a circle with the trip V.

When it is desired to turn a log, it is released from the head-blocks and motion is imparted to the wedge-beam K. This raises the logcatchers E E and the trip V simultaneously,

v so that by the time the tops of the log-catchers are even with the head-blocks,where they are held by means 'of the flat portions of the wedges L L, the trip V has moved up sufficiently to roll the log from off the carriage onto the inclined ends of the catchers. The

free end of the frame then drops over thetop ofv the pawl @which permits the throwingbar T and the trip V to drop back out of the way. By this time the wedges M M upon the side of the beam engage with the lower ends of the loading-levers J J, which causes their upper ends to bear against the log and force it back upon the head blocks against the knees, the inclined ends of the catchers greatly facilitating this work. The beam K is nowr drawn back to its former position, the free end of the frame O passing under the pawl Q to its original position in front of the pawl, and

lthe catchers E E,with the loading-levers, also drop back into their original position, where they remain until it is desired to turn the log again, when the same operation is again-repeated.

By having the top of the throwing-bar T made long enough to extend in front of the frame A, the device will operate withthe earriage at any point in which the bottom of the tripping-bar X is above any portion of it, thus avoiding the necessity of having to stop the carriage at any particular place.

Instead of placing the wedge-beam parallel with the track, as shown, two beams can be used by placing them at right angles to it, having one under each of the log-catchers, and the loading-levers can be operated by pawls or latches the same as above described for operating the tripping-bar, and for longer logs additional log-catchers and tripping-bars may be provided by extending the frame and wedge-beams.

Having thus described our invention, we claim- 1. In a log-turner, the combination of two upright log-catchers adapted to move vertically at the sides of the front posts of the millframe, a loading-lever pivotally secured upon one side of each of said catchers, a trip upon the carriage, and a wedge-beam for operating said catchers, levers, and trip, substantially as described, and for the purpose set forth.
