ESPECIFICATION forming part of Lettefslatent No. 342,536, dated May 25, 1886.
' Application filed December 31, 1884. Renewed January 20, 1886. Serial No. 189,179. (No model.)
To aZZ whom it may concern:
Be it known that I, -W1LLIs J. PERKINS, of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Log-Haudlers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My inventionrelates to a combination loghandler for handling logs previous to and during the operation of being cut into bolts, the object being to provide devices whereby a person by means of a set of levers may adjust the machine to a log of any dimensions, level it, regulate the distance of its travel, aid in moving it lengthwise, and also aid to hold it rigidly in place while being cut. r A further object of my invention is to provide a device of this character which shall be simple and capable of being easily and readily operated and strongand durable in-use; and with these ends in view myiuvention consists in certain details of construction and combinations of parts,as will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a View in perspective'of my improved device, the drag-chains, driving parts, and foundation-timbers being omitted. Fig. 2 is a View in side elevation. Fig. 3 is'a top plan view thereof. Fig. 4 is a-view in end elevation.
A representsapillar-casting rigidly secu red 7 at its lower end to a beam, a, of a suitable frame or foundation, to which casting ispivotally secured a yoke, a; In this yoke are mounted two friction -rolls, cf, the ends of which are provided with pinions a meshing with each other, to the outer end of the shaft of one of which rolls is secured a band-wheel, B, through which power is applied to the machine.
To one of the cross-beams of the main frame or foundation of the mill are secured hearings, in which is journaled a shaft carrying a friction-pulley, C, the shaft also carrying a small gear-wheel, 0, adapted to mesh with a gear, G, mounted on the main shaft D, thelatter being journaled in suitable bearings secured to one of the beams (Z of the main frame.
To the yoke a is secured or formed integral therewith a downwardly-projecting arm, a*, to the lower end of which is pivotally secured one end of a pitman, o the opposite end of which is connected to a lever, a, pivoted at a: to a suitable bearing. To the opposite end of the lever a is connected a pitmau, a the opposite end of which is secured to the lower end of the lever a pivoted at its center to one of the foundationtimbers. (Not shown.) It will now be readily seen that as the tworollers a are geared together they will travel in opposite directions, and by pulling on the lever a? one ofthe rolls will be brought into contact with the pulley O, and thereby impart its motion through said pulley and gears c O to the main shaft, and again by pushing on the lever a? the opposite friction-roll will bear on the pulley O, and the main shaft be turned inthe opposite direction, and when the lever is brought to a vertical position the yoke a will assume a similar position and hold both rolls out of contact with the pulley, and the main shaft D will remain stationary.
To the foundation-tinibers (l, cl, and d are secured bearingsd, in which isjournaled the shaft'E, provided on opp'ositesides of the central bearings, d, and between the homes (1" and d", with aright and left hand screwth read, the outer end of said shaft being provided with a bevelgear, 11 meshing with a similar gear, (1, loosely secured near the outer end of the main shaft 1). 1
F represents conerollers loosely secured on long nuts f, the latter being mounted on the shaft E, one on either side of the support d, the lower ends of these nuts extending downwardly beyond the iron'strap f secured to one of the foundation-timbers. I
To the main shaft D is loosely secured the gear d similar to the gear (1, and adapted to mesh with the gear al secured to the shaft or screw E, similar in construction and mounted in a similar manner to the shaft E. On this shaft are mounted cone-rollers F, in line with the cones F, the said cones being secured to long nuts f on the shaft, similar to the nuts f.
On the shaft D, and beyond the gear (i is loosely secured a similar gear, (1 with which meshes a gear, d", secured on the outer end of a shaft, E", similar to the shafts E and E and mounted in a similar manner. On this latter shaft, E, are mounted the nuts F, each carrying two rollers, f, mountedthereon, and also having depending arms fitting against an iron strap.
To the shaft D are rigidly secured two collars, e, between which fits one arm of a bellcrank, G, the other arm of the latter being connected to a pitman, g, which has its opposite end connected with a lever, g, pivoted at its lower end to one of the foundation-timbers, the said bell-crank being pivoted at a. By operatingthis lever the main shaft D is moved back and forth in its bearings, and also through the gears d d d", each of which 'is provided on its hub with a lug or projection. d,whioh, when the lever g is operated to pull the shaft D in a. direction toward the pitman g, engages it with a similar-lug, d, formed on a collar or clamp, 9 rigidly secured to the shaft. It will now-be readily observed that by operating the lever g'the gears d, d, and d may be locked to the shaft D, and by operating the lever a the shaft D set into motion,as before described, thereby turning the screws E, E, and E, whereupon the cones F, F, and F will be simultaneously moved toward or away from the centers of their respective shafts, the nuts on which they are secured being prevented from turning by means of the metallic strap f. By these means I am enabled to readily and easily adjust the machine for the reception of a log of any diameter and hold it securely in position and prevent it from rocking. After the cones have been properly adjusted the shaft is moved, thereby throwing it out of engagement with the gears d, (1 and d Between the shafts E and E is secured the rectangular frame H, to which are secured bearings h h, in which is journaled ashaft,,h", the latter being turned by means of a driven band-wheehh, keyed thereto, afriction-roller, H, being also secured to the shaft and near one end thereof.
Parallel to the shaft h is secured the shaft h, to which, near one endthereof and in line with the roller H, is keyed the large frictionwheel H, and near the opposite endthereof is secured the bevel-gear h meshing with a gear, H, mounted on one end of a shaft, h", which latteris journaled at right angles tothe shafts h h,secured to the frame H and to the foundation-timbers, the shaft h near its opposite end being provided with a sprocketwheel, h.
To the bearing h, which is adapted to slide on a. metal plate, issecured an arm to which is secured one end of a bell crank, theopposite end of the latter being connected with a pitman, h", connected with the lever hl,which latter is secured to the operating lever h". When the lever h is movediin one direction, the roller H is forcedagainst the'friction-pulley H, and thereby sets in motion, through the intervention of the gears h and H and shafth, the sprocket-wheel h. When the lever is moved in the opposite direction, the
roller H is pulled away from the pulley H and the sprocket-wheel h stopped. Around the wheel h passes an endless chain, the lower portion of which passes between the legs of the support d and the upper portion above the shaft E, the chain being provided with teeth which catch on the log to be sawed. By thus operating the lever the log may be drawn upon the coneswithout the necessity of handling or lifting it, thus saving a great amount of time and labor.
I represents a bumper or stop provided with a shoulder or step, 1', against which the end of the log' strikes when pulled upon the cones.
This stop is secured on its under side toa vertical shaft, 1, the lower portion of which is screw-threaded,.as shown at i, the rear end of the stop being hinged to ahorizontal beam, 1', looselysecured at its opposite end to a heavily braced timber, i. The lower end of the shaft passes through a central screw-threaded opening in a bevel-gear, '5', having an upper and a lower bearing secured to-one of the foundationtimbers and meshin with a similar gear, 1"", secured to one end 0 a shaft, i, the opposite end of the latter being also provided with a gear, 6 on its opposite end, the said shaft being journaled in bearings secured to the foundation-timbers. To one of the timbers is secured a bearing, i through which passes a vertical shaft having on its upper and lower ends a bevel-gear, i" and i, the latter meshing with the gear 1" and the former adapted to mesh with the gear 6, loosely secured to the shaft D, having a groove in its hub in which fits one end of the bell-crank 2", the opposite end of the latter being connected with the pitman i, which is. secured to the lever i, pivotedxat its lower endto one of the foundationtimbers. By moving this lever in one direction the gear 1' is slid on the shaft D in-mesh with: the gear 6-, and by operating the lever a thetwo gears are set in motion,which, through the intervention of the gears i i and a" and the shaft i, raise or lower the shaft or screw 1 and the strike or stop I. By these means the end of a logmay be raised or lowered, as I desired, and so held while sawing that the sawcnt may be parallel with the end of the log, thus wasting no timber, and also forming shingles from the upper and lower portion of the bolt of equal length. After the log has been raised or lowered the proper distance the lever i is moved in the opposite direction, thereby separating the two gears i and i, retaining the strike or stop'in its adjustment, and at the same time allowing the shaft D'to be turned in either direction without changing it.
K representsalog-dog hingedatk to'a heavy post in the mill-frame, and provided at its opposite end with depending pointed metal dogs k, adapted to enter the log and hold it in a stationary position, as will be hereinafter described.
To the dog or beam K is hinged the vertical rack-bar if, provided on its rear face with the guide-plate k, extending out beyond the sides of the rack This plate is fitted between four rollers, 70, mounted in a yoke, 70 the forward end of which slides in a grooved box or bearing, 70, secured to a frame-timber, It. lhe rack k is adapted to mesh with a pinion, k", secured to the shaft D, the rack being adapted to be moved out of mesh with said pinion by means of the rock-shaft k", which is connected with the pitman k the lower part being secured to the operating-lever is. When this lever is moved in one directiomthe roclcshaft, which is connected with the yoke k moves the latter in the box it, and forces the rack-bar 7c in mesh with the pinion 76 which, revolving with the shaft D, lowers the latter and forces the dogs is into the log, and securely holds the same against any movement while sawing, and thus prevents the breakage of saws. When it is desired to set the log ahead, the lever a is moved in the opposite direction and shaft D reversed, as before described, thus raising the dog K and allowing the log to be moved.
By means of my improved machine,timber, time, and labor are saved, one man only being required to operate the machine, all the levers being within easy reach of the operator. Again, any size log may be cut and held rigid in the machine, all danger of the log rocking or twisting being overcome.
It is evident that many slight changes in the construction and relative arrangement of the different parts might be resorted to without departing from the spirit and scope of my invention, and hence I would have it understood that I do not limit myself to the exact construction shown and described; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
