To on whom it may concern.-

. Be it known that I, VVILLIAM N. W HITELY, a citizen of the United States, residing-at No. 153 East High street, Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvementsin Mowing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the figures of reference. marked thereon,

which form a part of this specification.

My invention relates to improvements upon mowing-machines of the front-cut twowheeled hinged-bar type having a main or primary frame to which the tongue and seatsupport are rigidly attached and a secondary frame pivotally connected to the main or primary frame and to which the finger-bar is hinge-connected.

The object of my invention is to pivotally mount the lifting-lever for the finger-bar on this secondary frame and connect said lift-' ing-levcr with the shoe of the finger-bar by a pi ,votal'connection further, to provide alocking device for said lifting-lever on said secondary'frame to lock the lever when the finger-bar is raised from the ground and to hold the finger-bar in any desired elevated position wholly independent of the main or pricated wholly upon said secondary frame. I

many frame; also, to provide a spring to assist the operator in lifting said finger-bar andconnect said spring with said lifting-lever on the secondary frame. This spring may be lofurther provide a manual and automatic gear disengaging and engaging mechanism for stopping and starting the movement of the cutters when the finger-v bar is raised and lowered. upon the secondary frame and partly upon the main. or primary frame and is pivotally connected together near the pivotal connection of the secondary frame to the main or primary frame on its grassward side. The

' lifting-lever for the finger-bar and its con- This mechanism is located partly vertically, when desired, by its lifting-lever mounted on the secondary frame. I further provide for the easement of the secondary frame from the ground by means of a spring interposed between the main or primary frame and the secondary frame. I also provide a foot or hand lever located on the main or primary frame and connect same to the secondary frame by a link connection. A lockin g device for said lever is also provided, so that when the secondary frame and lifting-lever mounted thereon and the inner end of the finger-bar are raised from the ground they may be locked in their raised position.

While the above are my main improvements, there are other novel and important features, which will more fully appear by reference to the drawings and specification of this application. I

I attain these objects by the mechanism illustrated in the accompanying drawings, in which-'- Figure 1 is a plan view of a mowing machine of the type described embodying my improvements. Fig. 2 is a plan view of a portion of a mowing-machine of the type described, the main or primary frame being partly broken away, so as to show the diago-' ing the pivotal support of the shoe of the finger-bar to the secondary frame, the lift-lever, lift-lever stand, and the assisting-spring, also shows the manner of mounting these parts on the secondary frame independently of the mainorprimary frame.

Fig. 14 is a side View of the foot-lever mechanism pivotally mounted on the main or primary frame for lifting the inner end of the finger-bar and secondary frame, shown in plan in Fig. 1, also the locking device for the foot lever. Fig. 15 is a front view of a mowing-machine embodying my improvements, the heavy lines show ing the finger-bar in a semi-elevated position, at which point the drivinggearing for the cutters is positively disengaged by the downward movement of the lifting-lever, the dotted lines showing the vertical position occupied by the finger-bar when the lifting-lever has been drawn to its farthest downward position.

Those parts common to all mowerssuch as the seat, the wheels, the knife and its connection, the finger-bar, swathboard, tilting mechanism, and gearingneed not be particularly described.

The particular devices of my invention and the manner in which I utilize them for the foregoing purposes will now be described.

Similar figuresreferto similarparts-throughout the several views.

Upon the main or primary frame 1 is mounted the driving-gearing 13 for the cutters, said gearing having driving connection with. the cutters by means of the pitman 12, the gearing 13 being mounted at the end of said main or primary frame on the stubbleward side thereof. The secondary frame, as shown, consis ts of two members, (designated on the drawings as 2 and 2,) although it may be constructed in one piece, one disposed transversely to the line of draft, the front member 2 having a ball-and-socket or universal diagonal pivotal connection with the forward extension part- 3 of the main or primary frame 1, as shown in Fig. 1 at 17. The front member 2 also serves as a protection to the pitman 1 2, the other member 2" of.

said secondary frame projecting rearwardly Fig. 13 is and pivotally connected with the main or primary frame 1 at the grassward side of said frame by means of the joint 14:, pivotally connected diagonally to the frame 1 by the pin 26. The front member 2 of said secondary frame has connection with a lever 38, mounted on the main or primary frame 1 by means of the link 47, the bell-crank 39, and intermediate connecting-rod 40 between the bell-crank 39 and lever 38, said bell-crank being mounted upon the stud 43 of the main or primary frame 1, and the lever 38, also mounted on the stud 44, secured to the main or primary frame 1. Mounted on the stud 52 is the latch 53, as shown in Figs. 1, 2, 14, and 15. \"Vhen it is desired to lift the secondary frame and inner end of the finger-bar from the ground, the le ver 38 is pressed downward, and by its pivotal connections with said secondary frame and finger-bar lifts said parts from the ground, and when said secondary frame and fingerbar are thus lifted said lever engages the latch 53, which is mounted on the main or primary frame, forming a locking device to lock and hold the secondary frame and the inner end of the finger-bar in an elevated position from the ground. The spring '27 is interposed be- ;tween a rearwardly-extending portion 14 of fthe secondary frame member 2 and an inte- 1 gral lug 9 of the main or primary frame and ,is held in position by means of the pin 49, as shown in Fig. 7. .tains the weight of the secondary frame and Qthe parts mounted thereon and also assists lto-lift the secondary frame by means of the lever 38. To the rearward]y-projecting member 2 of the secondary frame is pivotally con- ;nected the shoe 6 of the finger-bar 10, said This spring partially susshoe pivotally connected by integral trunnions 51 51 in brackets 21 and 23, rigidly secured to said secondary frame. lever 8 and its parts are pivotally mounted The liftingon the member 2 of the secondary frame, as shown in Figs. 1 and 3, said lifting-lever being rigidly secured to the socket 7, said socket 7 journally mounted on the stand 19. From the forward endof said socket there extends a link 42, which is pivotally connected to the shoe 6 of the finger-bar 10 grassward of the pivotal connection of said shoe to the secondary frame. A- spring-rod 5 is pivotally connected at its forward end with the socket 7 and is supported by the bracket 18, mounted on the secondary frame. Said bracket 18 also serves to support the forward end of the rocknor does it exert a greater leverage on the finger-bar when the finger-bar is following a depression than when the finger-bar is pass-' ing over an elevation of the ground, the tension remaining the same no matter how uneven the ground may be over which the machiue travels. To those skilled in the art the advantages thus obtained will be apparent.

I will now describe the devices constituting the gear-disengaging mechanism of my invention.

To the lifting-lever socket 7, as shown in Fig. 6, is pivotally connected the tongue 33, which, when the finger-bar has been raisedby means of the lifting-lever S to the verti-. cally-inclined position shown in heavy lines in Fig. 15, said tongue 33 engages with the toe 34, which is rigidly secured to the rockshaft 35, Fig. 12, said. rock-shaft being journally supported from said secondary frame. As the liftinglever Sis drawn downward and as the finger-bar 1O assumes a vertically-inclined position, as shown in heavy lines in Fig. 15, said tongue 33 engages with the toe 34 onsaid rock-shaft 35, causing said shaft to rotate, turning the crank 36, which is rigidly secured to said shaft and to which is pivotally connected'the head 32 of the pullrod-31. The movement of the parts as above described results in the shifter-lever 30 moving the clutch 29 from engagement with the gearing 13, thus stopping the reciprocation of the cutters. Upon a further downward movement of the lifting-lever 8 the finger-bar 1O assumes a vertical position, as shown in dotted lines in Fig. 15, whereupon the plunger-bolt 45 of the lifting-lever socket 7 engages with the lifting-lever stand 19, and the finger-bar 10 is held and maintained in the vertical position described and shown by dotted lines in Fig. 15.

I provide a roller 37, secured to the apertured bracket 18, as shown in Fig. 12, the obj ect of said roller being to'properly guide said' tongue 33 into the aperture in said bracket 18 and to avoid friction of said tongue 33in its passage into and out of the aperture in said bracket 18 and'also to insure the proper engagement of the tongue with the toe 34 on said rock-shaft'35;

of the lifting-lever 8 the finger-bar 10 starts downward toward a horizontal position, and as said finger bar 1O descends and approaches the position shown in heavy lines in Fig. 15-

Upon the releasing the rock-shaft 35 is released from the action of said lifting-lever 8 and tongue 33, and the clutch 29" automatically returns to engagement by means of the spring 41, shifter-lever 30, and clutch-yoke 29;

It will be Observed that while the drivinggear-disengagingmechanism is partly located on the secondary frame and partly on the main or primary frame provision is made by swiveling or screw-theading the head 32 on the pull-rod 31 and-by placing it near the diagonal pivotal hinge connection of the member 2 of the secondary frame whereby the movement of the secondary frame up and down does not alfect the driving-gear-disengaging mechanism located on the main or primary frame in any position the secondary frame may assume within certain limits relative to the main'or primary frame. Thus the driving-gearing for the cutters is disengaged at a predetermined elevation 'of the finger-bar 10 whether the secondary frame is raised above or drops below the level of the ground. The pull-rod 31 is provided with an adj ustable head 32, so as to adjust the movements of the driving-gear mechanism and stop the reciprocation of the knife when the finger-bar 10 reaches a height beyond which it would not be practical for the pitman to reciprocate. The two forward-extendingportions of the main or primary frame areconnected together by means of the brace 15, so as to stiffen and strengthen said frame.

' The member 2 of the secondary frame is preferably riveted or bolted to the member 2 of the secondary frame, as shown at in Figs. 2 and 9; but other means of connection 'Of the members of said secondary frame may be employed that will connect said members together. The shoe 6 of the finger-bar 10 may be pivotally connected with the secondary frame in any convenient way, as the precise manner shown is not made a subject of claim cutters, a rearwardly-projecting member of' said secondary frame pivotally connected in' rear of said front member to the grassward side of said main or-primary frame, a hinge connection between said secondary frame and the inner shoe of the finger-bar, a lifting-1m verfor the finger-bar pivotally mounted on said secondary frame independent of said main or primary frame,'a connection fromsaid lifting-lever to said inner shoe of the finger-bar, a lockin g device for said lifting le ver on said'secondaryframe to hold the fingerbar in'an elevated position, the freeend of said secondary frame, and said lifting-lever and finger-bar free to rise and fall independently of said main or primary frame.
