ViOWlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 31%,541 dated March 24, 1885. n

Application filed February 13, 1884. (Model.)

To all whom, il may concern:

Be it known that I, EDWARD PRIDMORE, a citizen of the United States, residing `at Batavia, in the county of Genesee and State of 5 New York, have invented a new and useful Improvement in Mowing-Maehines, of which the following is a specification.

My invent-ion relates to improvements in mowing-machines of that class in which the i; cutting apparatus is located forward of the actuating mechanism; and the objects of my improvement are, first, to provide an easy method of tilting the cutter-bar by the driver from his seat upon the machine, and enable him, without stopping his team, to raise the point of the sickle-guards with the cuttingknives, so that the cutters will readily pass over stones or other obstructions without injury to the parts; also to be able, when de- 23 sired, to run underneath and cut any lodged grass that may be met with; second, to prol vide a flexible connection between the adjustable cutting-bar and the stationary part of the machine, so as to prevent cramping or strain- 25 ing the couplingbolts when in the act of raising or lowering` the said cutter-bar. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure lis a perspective view of the ma chine, with part of the frame broken away to show the crank-shaft. Fig. 2 is a cross-section of the same. Figs. 3 and et are detail views.

Similarletters refer to similar parts throughout the several views.

The main frame A, with the tongue A, carrying-wheels B,gear-wheel G,pinion O,cranl shaft d, and crank-wheel D, may be constructed in the usual and well-known manner, as these parts do not constitute any portion of my invention.

E is ashield secured in any suitable manner to that portion of the main frame which carries the crankshaft, and curved up to protect the crank-wheel.

F is the inner shoe, to which is bolted or otherwise secured the finger-bar G. This shoe has upon its front end a pin or spur, f, and atthe rear a lug, f', to which is secured a tubularbearing, f3, through which passes a 5o securing-bolt, f i, screw-threaded at its rear end to receive the nutby which the connect ing-link H2 is securely fastened against the end of the said tubular bearing. The forward end of this securing bolt also has a screw thread and nut, so that the coupling-arm Iand con- Vex-faced washer K2 may be held in true working position, as hereinafter more fully eX- i plained. This tubular bearing f" passes through an opening in the swivel-block HQ! g so that the finger-bar may be tilted forward or` 6c back, as well as folded up for transportation. i vThe vertical connecting-rod I'll is pivot-ed at its upper end to the short arm of the tiltinglever H3. This tilting-lever is provided with a spring-bolt, h, having a rod connecting it to the bell-crank lever hf, by means of which the` bolt is withdrawn from the notches in theA locking-plate if, formed in the are of a circle, l at whose center the tilting-lever is fnlerumedll I is athrust-bar, upon which is munnted thel 7o quadrant locking-plate h2, and which is pivoted to the mainframe upon the under side at apoint near the rearinner corner. This thrustbar has depending arms i i2 i, the` rear one,A i', supporting the swivel-block H. y `75 The central arm, i2, is recessed at its lower end, and within the recess the shoe-spurf plays, thus permitting the tilting of the fingerbar.

The arm i, extending from the forward end 8o of the bar I, is provided with adjusting-holes 1 t, for the reception of the arbor upon which the ground-wheel J is mounted.

The thrust-bar I is arched at c, for the purpose of allowing the play of the pitman (shown in dotted lines) while operating the sickle, also shown in dotted lines.

K is a coupling-bar pivotally connecting the arm of the thrust-bar with the shield E, and K is another coupling-bar pivotally eonnect- 9o ing the shoe with said shield. This bar K has acup-shaped end next to the shoe, theconveX portion of which enters the opening in the lugf of the shoe and a concave socketin the end of the tubular bearing ft.

concavity of said cupped end of the bar K is l inserted a convex-faced washer, through which passes the securing-bolt f2, and firmly unites all the parts in such a manner that the requisiteexibility is given the finger-bar verti- .roo cally, while the same is held in a rigid` posi` tion laterally. The object of this. concave` Into the convex conplingis to providea joint that shall jbeuniversal to a limited extent, and permit thenger-bar to be readily raised and lowered, A

bythe segment lifting-lever, as shown, or any other well-known device may be adopted, as

my invention consists only in the manner of constructing the operating devices for tilting the said bar and holding the same in true poisition. Itis well knownthat in the practical ioperation of mowing-machines small stones or vother obstructions often lie in the path of the cutters, visible to the operator, who is mounted upon the machine, which, unless avoided, will seriously damage these delicate parts.

In the use vof my device, when the cutter-bar is in the normal position and such damaging obstructions are met, the operator grasps the v f, 'tilting-lever with one hand, and, disengaging the spring-'bolt from the locking-notch, gives 'v .therequired movement to the lever, which,

through the jointed connection with the fingerbar, raises the points of the guard-fingers, and

l on aoconnt'of the flexible raising device the finger-bar is allowed to rise and ride over obstructions of considerable magnitude without `injury to the cutters. When the obstruction i's-passed, the tilting-lever and the finger-bar can be restored to their former positions withvonftj'the delayincident to stopping theteam, andwithout the expenditure of so much force as is requyisite'in raising the finger-bar bodily, asis usually done. Should lodged or tangled "grass be met, the operator can, by the use of the tiltin g-lever, throw the points ofthe guardfingers downfand under the matted portion, and thus cut the same without diculty.

' `Itvvill bei Observed that the cutter-bar in the tilting operation does not turn upon its longitudinal center, but as the hinge is in the rear of the bar the points of the guards are raised or lowered without giving the reverse motiony to the rear of said bar, as is usually done. y

The ground-wheel located in front of the cutter-bar is not a necessary appendage in the successful tilting of the bar, as the operation is easily performed without it; yet by preference the wheel is used to lighten the draft.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is"

l. The combination of the linger-bar, the shoe having the forwardly-projectingspur, the thrust-bar having the depending arm provided with a recess within which said spur'plays, and coupling-bars K K', all arranged and operating substantially described.

2. The combination of the finger-bar, the shoe, the rear extension of said shoe, thethrustbar provided with the notched quadrantplate, the bent tilting-lever, the means, as described, for connecting said lever with the finger-bar, and the ground-wheel, all arranged and operating substantially as described.

3. The combination of the finger-bar, the shoe having the front and rear extensions, the thrust-bar having the recess for the reception of the front extension of said shoe, the swivel- EDWARD PRI DMORE.
