LOG-TURNER.
SPECIFICATION forming part of Letters Patent 1Y0. 699,085, dated'April 29, 1902. Application filed October 11, 1901. Serial No. 78,297. (No model.)
To all whom it may concern:
Be it known that I, THoM s HINGSTONE DILLON, a citizen of the United States, and a resident of Leesville, in the parish of Vernon and State of'Louisiana, haveinventeda new and Improved Log-Turner, of which the following is a full, clear, andexact description.
This invention relates to improvements in machines for turning logs on a sawmill-carriage; and the object is to provide a machine of this character that will operate rapidly without jar to turn either round or square timber and so constructed that the turner will bear evenly andyieldingly against the log.
I will describe a log-turner embodying my invention and then point out the novel features in the appendedclaims.
Reference is to be had to tlie'accomp'anying drawings, formingapartof this specification, in which similar characters'of reference indicate corresponding parts mall the figures.
Figure 1 is ajsectional elevation of a logturner embodying'my invention. Fig. 2 is a similar view, but showing the parts in another position. Fig. 3is'asection on=the line 3 3 of Fig. 2. Fig. 4 is a rear elevation, partly in section; and Fig. 5 isaplanview.
The frame of the machinecomprises front uprights 5and rear uprights6,'and'the front and-rear uprights of aside .are connected by top beams 7. Mounted on thetopof the frame are inclined skids or runways 8 for -the log. Movable in the frame isthe log-turning arm 9, which has a substantially Teshaped';head 10,-the front surface of whichisprovided withdepressions 11, which willreceivethe corners of the log or timber when the log or .timberto be turned is angularin cross-section. Oarried in the head 10'are the turning-dogs 12. I have here shown threeturning-dogs but it is obvious that agreater number may be employed. These dogs are pivoted'in' recesses of the arm 9 and connect by means of a bolt" 14: with a block 15, movable in the end of the arm. The sides of the arm are provided with mitted to the under side through a pipe39;
slots, so that the bolt 14 may slide back and forth with the block, and to prevent jarring motionof the arm when engaging with a log I provide cushions at opposite sides of the block 15. As here shown, thcse cushion's consist of springsldand 17, arranged atopposite sides of the block and engaging around bolts 18, passed through endiplates in the frame.
At its angle portion theaugle-lever 13 has trunnions 19,which'have bearings 20,attached toa cross-beam 21of the frame. The lower or horizontal member. of -the angle-lever is provided with a .slot through which a pin 22, carried by a cross-head 23, passes. This cross-head is'movable vertically in guides 24 and is connected to a piston-rod 25, said piston-rod beingextended from a piston 26, operatingin a cylinder 27, and with this cylinder steam-inlet and exhaust pipes 28 29 communicate.
Attached to the forward end of the arm at the lowerside is an' inclined runner or rail 30. This runner or..railihas'on its lower edge a flange 31-, which=rests upon a roller 32, carried by a cross hea'd'33,movable in guides 34, and also attached to the cross-head are rollers 35, which bear upon the upper surface of the flange and keep the track or rail in close connection with the roller 32.
Movable in a steam-cylinder 36 is a piston 37, from which a rod 38 extends to a connection with a cross-head 33, and steam is ad of the piston 37 v The upper portion of thehead 10 is guided between plates- 40 on {the upper side of the machine-frame, and atthe forward ends these plates have stop-blocks 4:1, and at the rear ends are stop-blocks 42. These stop-blocks limit the movement of the arm 9 in bothits forward and backward movements.
' In'operation when a log Vis to be turned steam is admitted to the cylinder 36, and the 'upward movement of 'thepiston-will cause an upward. movement of the log-turning arm, and during this upward movement it will have a slight rearward movement, so that the dogs 12 will engage with the log and turn it. To cause a quick rearward movement of the turning-arm, steam may be admitted to the cylinder 27, forcing the piston 26 upward, consequently rocking the angle-lever 13 and drawing the turning-arm rearward. As the steam is exhausted from the cylinder 36, the turning-arm will fall by gravity to the position indicated in Fig. 1.
The depressions in the head 10, as before stated, permit the turning of a square log or timber, and this without using power in the cylinder 27. As the head moves upward the stick turns, and one corner passes into a recess in the head.
The cushion-springs before mentioned will prevent undue jar of the mill-carriage when the turning-arm comes in contact with the log and pushes it up to the knees, and the springs will also permit the arm to yield somewhat while turning a square timber against the same without aid from the angle-lever.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a log-turner, a turning-arm, dogs carried in the forward end of said arm, an anglelever with which the rear end of the arm has swinging and cushioned connection, a piston for rocking said angle-lever, and a piston for moving the forward end of the arm upward, substantially as specified.
2. A log-turner, comprising an arm having a head provided in its front surface with depressions or recesses, swinging dogs carried by the head and means for causing a vertical swinging motion of said arm, substantially as specified.
8. A log-turner, comprisinga turning-arm, dogs carried by said arm, a runner secured to said arm at its free end, across-head, a roller carried by the cross-head and on which said runner rests, a cylinder, and a piston in said cylinder having connection with the crosshead, substantially. as specified.
4. A log-turner, comprising aturning-arm, dogs carried by the forward end of said arm, an angle-lever pivoted in the frame of the machine, a block arranged to slide in said turningarm, a connection between said block and the angle-lever, springs arranged in the arm at opposite sides of said block, and means for rocking the angle-lever, substantially as specified.
5. Alog-turner, comprisinga frame, a turning-arm mounted to swing in the frame, dogs carried by said arm, a runner or track secured to the lower side of the free end of said arm and arranged at an angle to the length of the arm, a cross-head movable in guideways, a roller mounted in the cross-head and upon which said runner or track rests, rollers carried by the cross-head for engaging with the runner or track above the first-named roller, a cylinder, and a piston in the cylinder having connection with the cross-head, substantially as specified.
(3. In a log-turner, a frame, a turning-arm mounted to swing in the frame, an angle-lever mounted to rock in the frame, a swinging and cushioned connection between the upper portion of said lever and the arm, a crosshead movable in guides and with which the lower member of said angle-lever engages, a cylinder, and a piston in the cylinder connecting with said cross-head, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
THOS. HINGSTONE DILLON.
