SAWING-IMACHINE.
SPEClIFICAfIION forming part of Letters ratent No. 521,317, dated June 12,1894.
v Application filed September 25, 1893. Serial No.486,44'7, (lie model.)
To all whom it may concern:
Be it known that I, JOHN J ILEK, a citizen of the United States, residingat Monticello, in
the county of Jones and State'of Iowa, have invented a new and useful Sawing-Machine, of which the following is a specification.
' The invention relates to sawing machines; and it has for its object to provide certain improvements in portable sawing machines, whereby the same can be carried from point to point to saw heavy logs as Well as small timber.
-To this end the invention primarily contemplates an improved portable sawing machine, which can be readily operated by one or more persons to rapidly and efficiently saw logs, or timber which can be placed on the frame of the machine.
With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed In theaccompanying drawings:Figure 1 is a perspective view of a sawing machine constructed in accordance with this invention. Fig. 2 is a central vertical longitudinal sectional view thereof. Fig. 3 is a vertical transverse sectional view on the line 3-3 of Fig. 2. Fig. 4 is a detail in perspective of the swinging Weight arm.
Referring to the accompanying drawings A represents'an elongated portable framecarrying at one end the axle B, on the spindles 'of which are journaled the, wheels 0, which provide for the transportation of the machine from place to place, while at the other forward end of the frame are pivoted the folding supporting legs D, which when let down support the frame A,-in a horizontal position ready for the operation of sawing. Arising from the opposite side bars of the frame A, in front and rear of the'axle B, are the frame uprights E, which support a supplemental frame 6.
J ournaled in suitable boxes F, on the frame 6, is the horizontal crank shaft G, having the oppositely disposed cranks 9, arranged at both sides of the central gear Wheel H, carried by said shaft between the cranks there of. Connecting arms or links I are loosely pivoted atj, in the bracketsj, which are secured to the upper side of the horizontal cross bar or cleat K, connecting the opposite side bars of the frame A, intermediate of their ends. The said levers J, extendbeyond their point of pivot or fulcrum to and beyond the front end of the frame A, and are arranged on opposite sidesof the central combined seat and rest bar L. The combined seat and rest bar L, extends longitudinally of the entire frame and is firmly secured to the horizontal crossbar or cleat K, and has arising therefrom in front of the frame 6, the vertical rest or upright Z, against which the wood to be sawed rests when placed on the front end of said bar L, and the front ends of the side bars of the frame A, from which also arise the auxiliary rests Z, in a line with the rest of the bar .L. An ordinary seat M, is supported above and from the extreme front end of the bar L, so
that the operator can tread the levers J, so as to alternately vibrate the connecting arms or links I, and thereby communicate motion to the crank shaft G.
Adjacent to the crank shaft G, and journaled in suitable boxes on the frame 2, is the horizontal counter shaft N. The counter shaft N, carries a small pinion or cog wheel n, meshingwith the large gear wheel H, of the crank shaft, so that said counter shaft is driven and speeded from said gear wheel, and said counter shaft carries at one end the heavy balance wheel 0, which serves the usual function of a balance wheel. At the other end of the counter-shaft N, is carried a crank-wheel P, to the crank of which is loosely connected at one end the pitman p, the
other end of which is pivotally connected to the swinging saw arm Q. The swinging saw arm Q, is pivoted at g, at its upper end to one of the front frame uprights E, and is held steady in its vibration by the slotted guide q, secured to said upright so that the arm Q, can move therein. Pivoted at its inner end to the lower swinging end of the saw arm, is the straight saw R, which is designed to be raised onto the wood placed on the frame so that as the saw arm vibrates the said saw will be reciprocated: through the wood. The outer end of the reciprocating saw R, is held steady by one of the operators, and is itself guided in the slotted or looped guide r, embracing said saw and extending above the front end and at one side of the frame A above the plane of the upper ends of the rests Z and Z, as clearly illustrated in the drawings. If it is desired to saw big logs or heavy timber, the position of the saw can be reversed. as shown in dotted lines in Fig. 1, so that it will then extend and work from the rear end of the frame.
Pivoted at its lower end to one of the frame uprights E, opposite the saw arm is the swinging weight arm S, to the upper end ofwhich is secured on the pivot s, theweight bar 8, carryingat one end the weight T,while to the other end of'the same is attached thelifting cord or strap 1, which is also connected to the top edgeof the saw as'at t, and which while allowing the saw to be reeiprocated through the wood, at the same time automatically lifts the saw up into position for sawing another section after it haspassed through thewood. The weighted bar 8', is sufficiently heavy to elevate the saw when not in use. Projecting from the lower end of the swinging weight arm S, is the hook U, to which is attached one end of the auxiliary cord or strap u, whichis also attached to the top edge of the saw, so that when the same has passed through the wood being sawed, it pulls on said hook and prevents the saw from dropping, While at the same time bringing the arm S, in position so that thebar s, can drop into its lowest position.
As alreadystated, thewood to be sawedcan be placed on the front end of the frame A, and the bar L, against the rests Z and l", and is securely chained or bound in position by means of the binding chainor ropeV', one end of which is secured to the cross bar or cleat K, and being passed around the wood, the other end of the chain or rope is connected to the lever hook W, of the lever w. The lever w, is pivoted to the inside of one of the side bars of the frameA, and carries a of the toothed segment Y, arranged adjacent j to said lever, so that by means of said lever the chain or rope can be drawn tight and held so.
From the foregoing it is thought that the construction,operation and many advantages of the herein-described sawing machine will be readily apparent to those skilled in the art, and it will of eoursebe understood that changes in the form, proportion and theminor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention.
Having thus described my invention, what I claim, and desire to secure by Letters Pati. cut, is-
1. In a portable sawing machine, the combination of an elongated wheeled frame hav- :ing a rest portion at one end anda series of vertical rests arising from said rest portion "for the material to rest there-against, a supplemental frame supported on one end of the I wheeled frame, a swinging saw arm pivoted at one end to one side of the supplemental frame, a slotted guide for said saw arm, a :double crank shaft journal'ed on said supplemental frame and carrying a gear wheel, a counter shaft geared with the crank shaft and having a crank wheel at one end, a pit- {man connected to saidcrank wheelandto the swinging saw arm, extended treadles or foot levers pivotally mounted on the wheeled frame and extended beyond one end thereof,
connecting arms connected to the inner ends a of the treadles and to the cranks of the crank i shaft, a reciprocating sawpivoted at one end 1 tothe swinging endof thesaw'arm, an upright slotted guide extended from one endof the wheeled frame above the plane of the l vertical rests to accommodate the movement of the freeend of the saw, an operators seat ;supported above and between the extended ends of the treadles, and an automatic lifting 1 device for the saw, substantially as set forth. 2. In a portable sawing machine, the comlbination of the frame, a swinging sawarm, means for swinging said arm, the reciprocatring saw pivoted at oneend to said saw arm, a swinging weight arm. pivoted atits lower end to the frame opposite the saw arm and having a hook projectingfrom its lower end, weighted bar arranged at the upper end of fthe'arm, and cords or strapsconnected to one end of the weight bar and the top edgeof the ijsaw and to the hook and' the saw, substantially as set forth.
In testimony that I" claim the foregoing as ;my own I have heretoaflixed my signature in the presence of two witnesses.
JOHN J ILEK.
