MowiNc-MACHINE.
SPECIFICATION forming part of Letters Patent No. 251,389, dated December 27, 1881. Application filed April 29, 1881. (No model.)
To all whom it may concern:
Be it known that I, ANDREW TELFER, a citizen of the United States, residing at BOS- ton, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Mowing-Machines; and I do hereby declare that the same are fully described in the following specication and illustrated in the accompanying drawings.
1o This invention relates to improvements in mowing-machines; and it consists of an improved mechanism for converting the rotary motion of the drivingshaft to a reciprocating motion on the scythe, such mechanism being equally well adapted for horse-clipping and other machines in which it is desired to convert a rotary motion into a reciprocating one,
as will now be herein more fully shown and described, reference being had to the accomzo panying drawings, in which- Figure l represents a plan View of my invention as applied to a mowing-machine, and Fig. 2 represents a cross-section on the line A B shown in Fig. l. v
Similar letters refer to similar parts wherever they occur on the different parts of the drawings.
a a represent the driving-wheels, as usual, secured to the shalt b, whichlatter is made to 3o revolve in the bearings c c c in the ordinary manner when the machine is drawn over the ground.
d is the draw-bar.
e is a frame uniting the bearing c to the drawbar d, as shown.
fis the cutter-bar, with its guard-fingers g g and reciprocating Scythe h, in the usual manner.
i is the bar to which the cutter-barfis joint- 4o ed at lo, as shown, the opposite end of the bar i being hinged, as at Z, to the frame e, as usual.
mis a spur-wheel secured iirmly to the driving-shaft b, which spur-wheel is geared into the teeth of the pinion a, thelatter being loose on the intermediate shaft, o, that isjournaled in bearings secured to the draw-bar d and frame c, or other stationary parts of the machine.
To the shaft o is secured thedrum or cylinder p, which is provided on its circumference with two alternating rows of pins or projec- 5o tions, q q q q', between which is arranged the upper end ofthe lever r, that is provided with cams r fr on its two opposite sides, as shown. The lever 1' is hung on the fulcrum-pin s to the bar i, as shown, its forward end beingjointed at t to the scythe rod or link t, the opposite end of which is jointed at t" to the inner end ot the scythe h.
a is a lockinglever for the purpose of connecting or disconnecting the clutch a or simi- 6o lar locking device to and from the drum p. A slot-hole, c, is made through the forward part of the lever r, through which is inserted the guide-bolt o', passing also through the bar i,
as shown, for the purpose of holding said le- Ver a* in its proper position on the bar i during the reciprocating motion ot the said lever 1'.
The operation of the' device is as follows: When the machine is drawn forward over the ground a rotary-motion is imparted, by means 7o of drivers a a, shaft b, and spur-gears m u, to the drum or cylinder p. The alternating rows of projections q q q q during their rotation causethe llever r to be reciprocated on its fulcrum s by the cams or inclines r' r, being act- 75 ed upon respectively by the pins or 'proj ections q q q q', and in this manner a reciprocating motion is imparted to the rod t and the Scythe h without any extra gearings, save the ones, m and n, heretofore described.
When it is desired to drive the machine on the road without working the seythe, it is only necessary to disconnect the pinion a from the drump by means of the hand-lever u and clutch a', or similar or equivalent devices, and then 85 to raise the cutter-bar and scythe, as usual.
The device as shown for imparting a reciprocating from a rotary motion, is very simple in construction, is composed of very few parts, has Very little frictional resistance, and con- 9o sequently can be operated with a minimum of power as compared withk other devices now in use for this purpose.
I desire to state that I do not claim the particulararrangementofthecutter-bar,itsscythc, and connections to the frame, as shown and described, as such are well known iu mowingmachines now in use; but
vWhat I desire to secure by Letters Patent, In testimony whereof' I have affixed my sigi and claim, is@ 11a-ture in presence of two Witnesses.
In combination, the rotary drum l), its alternoting pins or projections q q', the curved rook- ANDREW TELFER. 5 ing lever r, adapted to fit the surface of the drum p, and provided with curved Cain-faces Witnesses: r 1^, slot-hole fu, and guide-bo1t o', as de- J AMES FAIRBAIRN, scribed, and for the purpose set forth.
