Description

Specification forming part of` Letters Patent To all whom 'it may concern: y Be it known that EPHRAIM FIHERRING- ToN and J osIAH HERRINGTON, late of West Hoosick,in the county of Rensselaer and State of New York, invented certain new and useful Improvements in Mowing-lvlachiues, of

description, reference being had to the accompanying drawings, making part of this specitication, in which- Figure lis a pla-n of a mowing-machine embodying their improvements. Fig. 2 is a side elevation of the same with one wheel removed.

Similar letters of reference indicate correspondinglparts in both figures.

The invention relates to the manner of supporting the laterally-proj ecting hinged cutting apparatus in atwolwheel forward-cut machine; to the means for compensating for its backward deflection in use; to the means for raising and lowering the cutting apparatus, whereby either the heel or the point of said cutting apparatus, or both, may be raised by the driver on the machine by the operation of a single lever; to the arrangement of the drivingmechanisin in connectionwith the means for throwing into and out of gear; and to the construction ofv the joint between the cutter-bar and pitman or conneclin g-rod, as hereinafter explained'.

To enable others skilled in the art to make and luse said invention','I will proceed'to describe its construction and operation.

the draft-frame, both of which are secured to the axle a(tl1e`latter by a hinged attachment) in such manner as to be'adjiustable relatively to eachother at any desired angle. D D are two` driving-wheels, journaled upon the axle a, and provided with cog-gearing, with pinions B B journaled loosely upon the main drivin g-shaft C, but imparting motion4 thereto when the machine is in gear, and moving forward through the mediunimf clutches constructed as follows: c c are collars, secured to the shaft C, and constructed with sockets for the reception of pins d d, which engage with ratchet-teeth on the inner faces of the pinions B.

ing upon shoulders and the lpin d and collar c, as clearly shown in the sectional View in Fig. l. The yheads of the pins are held in disks or yokes d2, sliding loosely upon the shaft, and adapted to withdraw the pins simultaneously from both pinions, when it isdesired to throw the machine out of gear, by means of I, crotchlevers cl3, connecting-rods d4, and a wedge, d5, operatin g 011 the connecting-rods, to draw the crotched end of the levers du toward the center of the machine. T is a slotted standard, projecting upward from the main frame to support the wedge d5 and guideitin aproperpath. Gearinge c, shaft f, crank-wheel f', and connectingrod gv transmit motion from the shaft C to the cutter-bar Gr. The rod q is connected with the cutter-bar by a double horizontal hinge-joint, which e'ectually prevents any horizontal play between them, but permits the connecting-rod to work at any angle without binding. The finger-bar H is secured to a shoe, I, the construction of which is clearly shown in Fig. 2. t' represents a wedge-shaped plate interposed between the finger-bar and shoe, and adapted, by being reversed in position, to vary the angle of presentation of the former. J is a metallic bar, rigidly secured to or forming a rear brace extension of the shoe, extending backward,

and hinged at j to the rear end of the main frame. K is a brace-rod, hinged at k to the bar J, and extending laterally to the opposite side of the main frame, to which it is attached adjustably by a screw-bolt and nuts, as shown at k in Fig. 1. L is a segment, pivoted at l to the draft-frame, provided with a hand-lever, ll, and adapted vto raise the finger-bar at either or both ends by means of a chain or cord, Z2, attached to the shoe or its connections. M is a spring foot-latch, operating in connection with ratchet-teeth on the inside of segment ll,.to retain the latter'in any position inwliich it may be set. N is Va rack, hinged atits l'ower end to a rigid projection from the shoe-brace J, and passing upward through a slotted plate, n, in the draft-frame, against the front of which the said rack is pressed with the foot when it is desired to hold down the heel of the linger-bar. At other times the rack is kept out of gear by a spring-bar, n. While the rack is in this position the'segmcnt-lever L l* will raise only the heel of the finger-bar, the point resting on the ground; but by pressing the rack N forward with the foot the heel of the ringer-bar may be held down at any desired point, and the segment-lever will then act to raise the point, the rack N acting as a fixed point or fulcrum, on which the nger-bar turns.

O is the drivers seat. P is the tongue. Q is a perforated bracket, extending laterally from the tongue for the attachment of the double-tree R in any desired position to counteract the side draft of the cutting apparatus.

The angle between the main frame A and draft-frame Al is adjusted by means of a perforated standard, S, extending upward from the front of the former, and supportin g it at any height by a pin, s, insertedy through the said bar into the tongue. By this means the connecting-rod may be adjusted to work in line with the cutter, at any height of the latter.y A stop-pin (represented by a dottedcircle in Fig. 1) projects upward from the shoe I, i y

' i operating upon Vthe heel end of the cutting immediately beneath the connecting-rod g, for

the purpose of supporting the cutter when turned up to a vertical position. y

When it is desired to convey the machine from place to place without using thecutting j mechanism, the pin s is first Withdrawn, and the segment-lever L l1 and foot-rack N employed to raise the finger-bar nearly to a vertical position. The rack N is then withA drawn, and the continued motion ofthe lever causes the rod K to engage bencaththe frame A, and vdraws the latter closely up against the frame A', where itisheld by means of the footlatch M. When theffnger-bar is thus raised toa vertical position the cutterbar slips through its guides until it rests upon the pin in the shoe previously referred to.

supported by means of a bar, U, hinged to the main frame at u for this purpose. y

What is claimed as the invention of the said Erminia F. and JosIA'n Hnnnnveroiv Y 1. A shoebrace whichv is rigidly attached toj the linger-bar, and which extends backward.

between the drive-wheels on aline parallel, or`

The 1in= f ,ger-bar is inclined over the frame and there of a hinged cutting apparatus with the main flame, in such manner that both ends of said cutting apparatus, each end independently of the other, may be raised by the attendant on the machine by the operation of a single lever.

H5. The combinationof a lifting mechanism with the hinged cutting apparatus, in such manner that said cutting apparatus may be raised or turned up into a vertical, or nearly vertical, position, for passing obstructions, by the operation of a single lever by the driver on his seat on the machine.

6. A lifting-lever provided with an internal segment-rack, for the purpose specified.

7 A lifting-lever provided with a segmentrack, in combination with a foot-latch, for holding said lever, as desired.

8. The combination of a lifting-lever with v a hinged cutting apparatus, which can be turned up4 by the eine of the machine, and a foot-latch'for holding said lever when ythe cutting `apparatus is raised. i

9. The foot rack or bar, or its equivalent,

apparatus, to hold said end while the point of the cutting apparatus is being turned up, as set forth.

10. The combination of the footrac'k and the segment-lever, or their equivalents, for the purpose specified'. v

1l. The employment of a spring for holding the foot-rack out of gear or lock, when not in use, to allow the cutting apparatus to follow the surface of the ground over which it is 12. The arrangement ofpinions on the opposite endsof the counter-shaft, in combination with a mechanism for simultaneously throwing said pinion'sinto or out of gear.

13. The employment of the pivoted levers d3 da, forked:k at one end, and operating in the manner andfor the purpose specified. l

14. The employment of the wedge d5, for the 1311.111059 SDBIB@ 15. The double horizontal hinged connection between the heel of the cutter-bar and the Connecting-rod '16. The reversible wedge, or its' equivalent, for changing the angle of presen tation of the cutters` to the ground.

17. The combination, in a harvesting-machine, of/thefollowing' elements,` viz: a main frame,- an independent seat and tonguefram,

- and a hinged cutting apparatus, which is free at f each end, independently of the other end and of the main frame, to follow the surface of the ground-over which it is drawn.
