LOG-SETTINGAPPARATUS FOR SAW-MILLS.
SfECIFICATION forming part Of Letters Patent NO. 269,123, dated December 12, 1882,
i Application filed September 2, 1882. (No model.)
To all. whom at may concern I Be it known that I, \V'ALTER P. SCOFLELD, p of Cedar Keys, in the county of Levy and My invention consistsof apparatus by which the-sawyer is enabled to gear the log-shifting devices of the carriage with a shaft located alongside of the carriage, so as to shift the same 'forward or backward at will, as hereinafter fully described.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a plan view of'a log-carriage for circular-saw mills with my improvements applied to it. Fig. 2 is a transverse section of. the carriage, track, and drivingshaft, and side elevation of the setting apparatus. Figs. 3
r and at are details.
The carriage a, ways or tracks I), head-block c, sliding knees d, racks e, shaftf, and pinions gare of the ordinary or approved constructionand arrangement.
To turn the shaft fand pinions g by power at the will of the sawyer for setting the log up' to the saw it from time to time, and for shifting the knees back when a newlogis to be put on, I arrange a longshaft, i, alongside ofthe carriage, atthe back,in suitable bearings,j,to becontinuonsly operated by a belt from any suitable drivingpulley and working on the pulley it. On this shaft I arrange the double pulley 1, so as to slide along it as the carriage goes by means of a fork, m, attached to a brackeun, on the carriage, and engaging the grooved hub 0, the said pulley having a key or feather, p, running in the groove qof the shaft, for being duly rotated thereby for driving, the friction-pulleys s and t by the belts to and c, the latter crossed for reversing the motion, said pulleys being mounted respectively above and below the friction-pulley w on the shaftfa-nd in the arms 3 and 2, which are pivoted to the carriage and suspeii ded from the hand-levera by rods 1) and a, so that by shiftin g the lever in one direction the wheel 3 will be made to drive wheel to in one direction, and by shifting it in the other direction wheel t will drive it the other way,
t will be disconnected and wheel to will be inoperative.
A scale, d, may be so located with reference movements of the knees thus produced.
kind the setting of the logs will be greatly simplified. At the same time it may be done accurately and quickly.
It may be preferred toemploy the pulley t the log up to the saw, because it is best held forcibly in contact with the wheel to for the the greater friction required when shifting the log.
In practice a spring will be arrangedunder arm y to prevent the contact of wheels 8 and to when not in working contact.
I am aware that it is not broadly new to employ attachments to saw-mills whereby the log may be laterally shifted by power under the control of the sawyer; but. i
What I do cl; im as new and of my invem tion is- The combination, with the carriage a and sliding double pulley land the grooved hub 0, the carriage-bracket it, having fork m, the
riage, the intermediate pulley, w, on shaftf, the belts u o, and the hand-lever a, connected by rods b with the pulleys s 1, whereby the logs may be set up to the saw and the knees shifted, as described. i

while-in the middle position both wheelss and for turning shaftfin the direction for setting shaftf, of the shaft 6, carrying the keyed and i to a pointer, e, on the knee cl as to gage the It will be seen that with apparatus of this friction-pulleys s t on pivoted arms of the car-
