this application filed 6,
To all whom it may concern:
Be it known that we, lVHrrLnY E. MAR- of l l inston-Salem, county of Forsyth, S vte of N orth Carolina; and GORDON Brynn, of Dallas, county of Dallas, State of Texas, citizens of the United tates, have invented certain new and useful Improvements in Gearing, of which the following is a specification.
This invention relates particularly to gearing for controlling the log carriage of a portable Saw mill.
The improvements are shown applied to a machine constructed in accordance with the patent of lVhitley E. Martin, No. 778,258, granted December 27, 1904 and, except as herein disclosed, the machine indicated in the drawings may be taken to be one constructed and operating in accordance with the description and drawings of that patent.
In the accompanying drawings: Figure 1 is a plan view partly broken away; Fig. 2, a side elevation; Fig. 3, a detail side elevation showing friction driving devices by which the movements of the log carriage are controlled; and Fig. i is a detail elevation at the right hand of the rear end of the machine.
The bed place or main frame A of the machine is carried upon appropriate running gear for transportation. lhe circular saw ll carried by a shaft 5 mounted in appropriate bearings and, in this instance, is shown provided with a pulley b for the reception of a driving belt. When the machine is in operation the shaft 6 is constantly driven and it is quite immaterial whether it be driven by external power or by a motor carried upon the machine. A. pulley b on shaft 7) is connected by a belt 6 with a pulley c on the transverse shaft C carrying a gear 0 intermediate its ends and at its outer end a friction wheel C of suitable construction and material. The gear a meshes with a gear (Z fast on a transverse shaft D carrying at its outer end a similar friction wheel D in suitable proximity to the one G. Suitably mounted to rock in hearings on the frame is a. transverse shaft E to the end of which, at the feed side of the machine that is, the inner side of 1 is secured an operating lever B which it is designed shall stand in vertical position when the log carriage i at rest. To the opposite end of the rock shaft E is secured a short downwardly extending radial arm 0 to which is coupled one end of a link (3, the opposite end of which is pivoted at c to the side of a rocking bearing F in which rotates a normally inactive shaft G to the outer end of which is secured a friction wheel G of suitable construction and material; and normally, when the machine is at rest, located symmetrically above the constantly driven fric tion wheels 0, D. The bearing F is pivoted upon a pin f carried in a vertically adjustable box j supported on its upper and lower sides by vertically disposed adjustable screws f and movable vertically in ways formed in a bracket H attached to the under side of the bed plate A. This bracket l-l, seen in Fig. 4, ha. also downward extensions in which respectively are the bearings of the shafts G, D, of the constantly driven friction wheels C, D.
On the shaft G carrying the friction wheel G is fixed a pinion g meshing with a rack I on the under side of the reciproeating log carriage I. When the machine is at rest, friction wheel G is out of contact with either of the constantly driven friction wheels C, D. If the hand lever E be thrown to the left. as viewed in Fig. 3, the link 0 will operate to rock the bearing F of the friction wheel G and bring the latter wheel into frictional engagement with the constantly driven friction wheel C, wheel G beingthereby driven in a direction to cause the pinion g on its shaft to advance the log carriage toward the saw. If the lever E be thrown to the right, wheel G is thrown into engagement with the constantly driven friction wheel I) and shaft is revolved in a direction to retract the carriage to the feed end of the machine. There is sufiicient play of the teeth of pinion g in those of rack l and also sulficient play of the end of shaft G in its bearing F to permit the rocking of the opposite pivoted bearing of the shaft. llhen the carriage is at rest the operating lever E will stand in vertical position. Should vibration of the machine tend to displace the lever from vertical position, sufficient friction may be applied to the bearings of the rock shaft E to counteract such tendency.
This case is a division of our application filed October 29, 1907, Ser. No. 399,671.
We claim:
1. The combination with two continuously driven friction wheels rotating in opposite directions, of a normally inactive driving shaft, a vertically adjustable movable hearing in which the shaft is mounted, a friction wheel carried by said shaft and normally out of engagement with either of the continuously driven friction wheels, and means for at will moving said bearing from normal position to bring the friction wheel on said normally inactive shaft into engage ment with either of the'continuously driven friction wheels.
2. The combination with two continuously driven friction wheels rotating in 0pposite directions of a normally inactive d iv ing shaft, a vertically adjustable rocking bearing in which the shaft is mounted, a friction wheel carried by said shaft and normally out of engagement with either of the continuously driven friction wheels, and means for at will rocking said bearing in either direction from normal central posi tion to bring the friction wheel on the normally inactive shaft into engagement with one or the other of the continuously driven friction wheels.
3. The combination with two friction wheels constantly driven in reverse direction, a normally inactive driving shaft, a friction wheel carried thereby and symmetrically disposed with reference to the constantly driven friction wheels, a rocking bearing in which the normally inactive shaft has a bearing adjacent its friction wheel, a
vertically adjustable box in which is carried the pivot pin of said rocking bearing, vertically disposed ways in which said box is mounted and adjusting screws above and below the box, and means under the control of the operator for rocking the bearing of the normally inactive shaft from central normal position to at will bring the friction wheel of said shaft into operative engagement with either one of the continuously driven friction wheels.
4. The combination of a normally inactive shaft, a friction wheel fixed to said shaft, two continuously driven friction wheels rotating about fixed axes and correspondingly located in juxtaposition to the friction wheel on the normally inactive shaft, a pivoted bearing in which the latter shaft is mounted, a rock shaft having an operating lever, an arm projecting from the rock shaft, a link connection between it and the pivoted rocking bearing of the normally inactive shaft whereby the latter shaft may be swung from its normally inactive position to bring its friction wheel into operative contact with either one of the continuously driven friction wheels.
In testimony whereof, we have hereunto subscribed our names.
