SPECIFICATION forming part of Letters Patent No. 223,572, dated January 13, 1880.

Application filed October 6, 1879.

To all whom it may concern:

Be it known that I, CHARLES M. YOUNG, of Corry, county of Erie, State of Pennsylvania, have invented certain new and useful Improvements in Mowing-Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which i Figure 1 is a perspective view of a mowingmachine embracing my improvements. Fig. 2 1s a plan view of the same. Fig. 3 represents a horizontal section through the coupling and pivot blocks intermediate between the cutting apparatus and the mainframe. Fig. 4 shows,

in perspective, said coupling devices detached.

Fig. 5 is a longitudinal section through the gear-frame and crank-shaft sleeve. Fig. 6 is a transverse section through the gear-frame, in line with the bearings of the secondary shaft. Fig. 7 is a perspective view of the up l per half of the crank-shaft sleeve inverted,

and Fig. 8 is a perspective view of the removable box in which the secondary shaft and the shaft of the shipping-lever have their bearings.

Similar letters of reference denote corresponding parts wherever used.

The invention relates to a novel construction of the divided crank-shaft sleeve adapting it to hold the removable sleeve-bearings of the crank-shaft in place, and also to brace the tongue-socket; to a novel arrangement of removable box for supporting one end of the secondary shaft, and the devices for throwing the machine into and out of gear; and to a novel construction and arrangement of the couplingdevices intermediate between the cutting apparatus and main frame, for giving increased strength thereto and facilitating the control of the cutting apparatus by the attendant.

The means for attaining these results will be understood from the following description with reference to the drawings, in which A represents the main or gear frame, made to inca-se the gearing, and provided with a hinged cover, A, and with sleeve-bearings for the rotating main axle on which the main carry ng and driving wheels B B are mounted, sald parts, as shown, in their general construction and arrangement, and except in particulars hereinafter described, being similar. to those in what is known as the Glimaxmowing and reaping machine, though other forms and arrangements may be employed, if preferred.

The main frame A and cover A divide about in the plane of the main axle and gear shafts, and the sleeve-bearings for the latter, cast with the frame part, rise about one-half their diameter above said plane, the cover being notched to accommodate the upper halves of the sleeves. By this arrangement the dividing of the sleevebearings, except for the crank-shaft, is avoided. The crank-shaft sleeve A A is divided on the same plane with the division between the main frame and gear-cover, and has sockets formed in it for the reception of removable bearingsleeves to a, one half of each socket being formed in the main-frame part of the crankshaft sleeve and the other half in the upper removable part or cap of said sleeve. By this arrangement the crank-shaft bearing-boxes a. a are made readily removable for renewal or other purpose, and all wear is removed from the sleeve A A while. at the same time the latter holds the boxes securely in place. The cap part A of the crank-shaft sleeve, in addition to the sockets above described for re: taining the boxes in place, is arched over the crank, forming a shield therefor, and has an arm or horn, A, formed upon it, which projects laterally and upward, and has its outer end bolted to the forward end of the hinged tongue-socket for bracing the latter and forming a rigid connection between it and the main frame, as hereinafter described.

The main axle b and the secondary shaft b" are inserted in their sleeve-boxes in the main frame from one side; but, to facilitate the insertion and removal of the secondary shaft b, the sleeve-bearing or box 0 at one end '(see Figs.6 and 8)is made separate from the frame A, and is formed upon a block or plate, 0, which fits within an opening formed in one side of the frame for its reception, and which,

when in place, is secured to a flange on the gear-frame by bolts or screws, as shown.

The plate 0 has pendent perforated lugs or ears 0 o, forming bearings for a short shaft, W, to "which the shipping-fork b is attached, the

shaft rocking in its bearings and in the eye or bearing in the fork, the latter being held upon its shaft 1) by a pin at c and engaging a groove in the hub or sleeve of the spur-gear B Said hub or sleeve is provided on its 0pposite end with a clutch-face, which engages a corresponding clutch-face on the pinion B A spring on the shaft b between its bearing-lugs, as shown, holds the wheels B B in clutch, and a hand or foot lever, b moving over an inclined face, 0 on the block or plate, serves to rock the shaft in its bearings and to draw it outward, overcoming the tension of the spring b and moving the wheel B out of clutch with the pinion B thus throwing the machine out of gear. Stops or shoulders at each end of the incline 0 limit the throw of the lever b By this arrangement the bearings of the secondary shaft can be made in socket or cup shape, as shown, (not passing entirelythrough the bearinglugs,) thereby preventing end movement of the shaft, while at the same time providing for the insertion and the ready removal of said shaft when required.

The frame A is provided on its lower face with two short laterally-projecting arms or lugs, a a, arranged one at or near the vertical plane of the axle-sleeves and underneath the same, and the other at the forward end of the crank-shaft sleeve. To these are pivoted the coupling and brace rods D D, the former extending laterally and the latter forward and laterally until they meet in a coupling-block, D provided with threaded sleeve-sockets dd for their reception, and having a rigid connection therewith. This block, aside from its sleeves connecting it with the rods D D, is made in L form, (inverted,) and has its outer vertical face or wall arranged about in the same vertical longitudinal plane with the outer side of wheel B. (See Fig. 2.)

The block D has near its rear end a horizontal perforation at 61 forming a bearingsocket for a pivot, E, on a second couplingpiece, E, and the forward end of said block D made in L form, extends outward beyond the main outer wall referred to and forms a standard, D for the support of a vertically-adjustable leading-wheel, F. Inside the projecting rear edge of this standard and between it and the main vertical wall of block D is formed a vertical groove, f, curved in the arc of a circle of which the pivot E is the center, for the reception and retention of the forward end of a tongue-plate, e, on the forward end of the pivoted couplingpiece E, this arrangement serving to relieve the pivot E of the strain due to backward thrust upon the cutting apparatus, while at the same time permitting the pieceE and the cutting apparatus connected therewith to rock freely on the pivot E as a center for raising or depressing. the points of the cutters.

The coupling-piece E, for the-main part, consists of a broad flat plate, made in one piece with the vertical tongue-plate e, arching in form, and terminating in pendent vertical ends or lips, to which the shoe Gris pivoted through corresponding lugs or uprights at g g on its ends, one in front and the other in rear of the cutting apparatus connected therewith.

The arrangement is such as to bring the points of the cutters into the same vertical transverse plane with the pivot E, thus adapting the cutting apparatus to berocked on said pivot for raising or depressing the points of the lingers without varying materially the height of cut. The pivot E extends through the block D and is provided with a sqfared shank or tenon, e, entering a corresponding socket in an upright arm or lever, h, secured thereon by a bolt or set-screw, as shown. The upper end of this lever-arm h is connected by a rod or link, i, with the lower short arm of a lever, I, pivoted in rear of the axle in pendent logs or ears is, formed on the tongue-socket K. This tongue-socket has a sleeve, K, at its rear end surrounding the main axle, and at its forward end may be connected with the crank-axle sleeve by an arm, A, on the crank-shaft sleeve, as explained, thereby making a rigid connection between the tongue and main frame when desired. In rear of and over the axle-sleeve the tongueplate has a toothed rack, k, formed upon it, and a sliding lock or bolt, 1', held engaged with said rack by a spring and thrown out by a thumb latch or lever, I, serves to hold the lever I at any desired adjustment. By withdrawing the latch and moving the le. ver I backward or forward, the points of the fingers can be rocked up or down, as desired, to adapt them to the surface over which the machine is drawn, or to the condition of the crop to be operated upon.

A second lever, J, provided with a quadrant sheave, and pivoted in suitable lugs at the forward end of the tongue-plate, and connected by a chain with theeoupling-block D serves to adjust the height of the cutters and to raise them for passing over obstructions or for transportation.

Parts of the machine not particularly de-.

scribed may be constructed and arranged in any usual or preferred way.

Having now described my invention, I claim- 1. The divided crank-shaft sleeve having 'the removable cap part or cover, provided with thehinged shoe G, substantially as described.

6. The combination of the hinged coupling 15 and brace rods D D, coupling-block D rigidly connected therewith, pivotal block E,and hinged shoe G, for connecting the cutting apparatus with the frame, all arranged andopcrating substantially as described.
