Letters Patent No. 109,178, dated November 15, 1870 antedated November 11, 1870.
IMPROVEMENT IN SAWiNG-MACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern.-
Be it known that I, JOHN O. Chinn, of Philadelphia, Pennsylvania, have invented certain new and useful Improvements in Foot-power S'awing- Machines, of which the following is a specification.
My invention consists of a combination of the driving-wheel, auxiliary double crank, and operators seat and bracing-rod, as hereinafter described.
Figure 1 represents a perspective view of the machine, a portion of the frame being broken away.
Figure 2, a plan of the double crank on the prolon gation of the driving-wheel shaft, and the operators seat and bracing-rod.
'Figure 3a perspective View, intended to show a modified form of the compound pitman; also, the attachment of the pitman at one extremity to the -crank' of the driving-wheel and at the other extremity to the treadle.
a is the frame of the machine, and bthe door on which it rests. l
c, the treadle, which turns on gudgeons or centersin theyuprights of the frame.
fl, the compound pit-man, the upper extremity of which is connected with the crank e on the drivingwheel f.
g is a pinion. It gears into the ,drivingfwheel and is placed on shaft h of the ily-wheel t.
j is the saw-head.
la is the double crank on the prolongation of the driving-wheel shaft.
m is the seat, and
.ma bracing-rod, for the use of an assistant oper` ator. The pitman d is made up of the oscillating lever p, thetwo slotted similar levers q and r, and the several levers s, the latter being united by exible joints, so as to constitute an expanding and contracting framework, as shown.
The levers q and o* have a vertical as well as an os.- cillating motion. Their upper ends are attached to the pin, which forms the middle'joint of the levers s, as show-n in fig. 1, and they oscillate on this pin; or, if the modified arrangement shown in lig. 3 is used, the levers q and r. are attached to the pin in the .topmost joint, as appears in this gure.
The levers q and r are provided with slots u., which enable thernto straddle the bolt v, which is thus caused to guide 1the lower end of the frame-work, composed of the jointed levers s.
The levers q and fr are attached, at their lower ends, by apin or holt, w, to the treadle, at or about the middle of the length of the treadle.
The lever 11 vibratcs on a fulcrnxn-pin, y, and is pro` vided with an opening, x, to make way for the curvilinear movement ofthe pirhw;A but, instead of forming such an opening-in lever p, the latter may be made solid, and curved or bent, so as to be out of the way of pin' w.
I prefer to inane the several parts of the pitrnan el of steel.
lThe machine is operatedeither by a single person or with increased powerby the aid of an assistant, who occupies the seat m and applies his feet tothe double crank 7a, bracing himself with rod a.
The compound pitman` may be advantageously applied to turning lathes 'and other kinds of machin- 011V- I disclaim the compound Apitman d, as that device appears in the patent, No. 68,074, granted to Edward Healy August 27, 1867. l
'.lhc combination of the double crank L, operators seat m, bracing-rod n, and driving-Wheel f, substantially as set forth, for driving a foot-power circular saw.
JOHN C. OLIME. Witnesses:
WM. It. WRIGHT, J. M. COLGAN.
