To all 'whom t may concern.' Be it known that I, EDWARD W. BURGESS, a citizen of the United States, residing at Chicago, I Illinols, have invented certain new and useful Improvements in Tractor-Operated Implements, of which the following is a full, clear, and exact specification. My invention relates to tractorv operated implements, and in particular to harvesting machinery, such as mowers, harvesters or the like. f. It has among its objects to produce an improved unitary constructionl which may be rigidly attached to a power unit; as, for instance. a tractor, in such a manner as to transform the tractor implement. A further object of my invention is toA produce an improved mechanism which may be of any desired size, preferably comprising a plurality of operatively connected harvester units which may be connected to a source of power; as, for instance, a tractor, and drawn thereby, the power for the harvesting mechanisms on the units preferably also being derived from the tractor. A further object of my invention is to pro-V vide a mechanism of the character set forth above having maximum capacity, in which the number of parts is reduced to the minimum, and the cost of manufacture is correspondingly reduced. These objects are obtained by means of mechanisms. one embodiment `of which, wherein my improvement is used in connection with mowers, being shown 'for purposes yof illustration in the accompanying drawings. In these drawings: Figure 1 is a top plan view of a tractor equipped with my improvement,v wo operative sections thereof being shown; Figure 2 isra sectional side elevation on r an enlarged scale of a part of Figure 1; Figure 3 is a cross section of the frame member illustrating the means whereby the machine frames are connected.` In the construction illustrated, 1 and 2 represent diagonally disposed front and rear v members, respectively, of the main frame of a mowing machine unit having a tubular frame member 3 secured thereto that is disposed in a fore and aft direction, and journaled therein is a shaft 4 having a bevel in the county of Cook and State of into a power driven pinion 5 secured to its rear end andfa crank wheel 6 to its opposite end. 7 representsa shaft having its opposite ends journaled 1n y, bearings 8. preferably integral with the frame member 3, and having a bevel pinion 9 secured ,n thereto and meshing with the pmion 5. Secured to opposite ends ofthe shaft 7 are coupling sleeves 1() adaptedto operatively receive the ends of the disconnectible driving shafts 11. 12 represents a diagonally disposed frame member connecting the front end of the member3 with the member 1. 13 represents a common form of journaled in a bea-ring block 14 integral with the rear end of lthe tubular frame member 3. As shown, this coupling frame member extends forward and grassward and is turned coupling' frame member having its rear end laterally at right angles with the line of i draft of the machine. Journaled on its grassward end is a common form of coupling yoke 15. 16 represents a supplemental couplingv frame member connecting the front' end of the yoke 15 with the front end of the frame member 3. .17 represents the inner shoe of the cutting apparatus pivotally connected with the yoke 15 in the usualway by means of pins 18, and having a cutter bar 19 secured thereto. the opposite end of the bar being equipped with a common `form of shoe 20 and swather members 21. 22 represents the guard fingers, 23 the sickle, and 24 the pitman connecting the sickle with the cran wheel 6. 25 represents' a toothed sector carried by the frame members 1 and 2. Operatively mounted on these members is a. detent controlled tilting lever 26 having its lower end connected with an arm 27 integral with the yoke 15 by-means of a rod 28 whereby the yoke may be turned about its axis in a manner to tilt the cutter bar in opposite directions in a common way. 29 represents a forwardly extending bracket member having its rear end secured 'to the frame' members 1 and 2. and its front end adapted to receive a bearing sector 30, upon which is pivotally mounted a detent controlled lifting lever 31', which has its forwardly extending arm 32 iexibly connected with thecutting apparatus by means of a common form of link and lever mechanism 33, a counterbalancing spring 34 connecting the lifting lever with the vupturned end 35 of the rear end of the bracket' 29. 36 representsa forwardly extending bar secured to the front end of the bracket 29, and having an eye member 37 at its front end whereby it is flexibly connected-with one end of a rod 38, having its opposite end provided with a securing nut 39 and adapted to be received by an opening 4Q in the cutter bar when said bar is raised to a vertical position vfor transportation purposes in the usual way. The power unit with which I combine my unitary construction to form a power driven implement is shown as a tractor of the fourwheel type, the front or steering wheels being omitted because of insuliicient room. The tractor has two side frame bars 41, 41 connected at their rear ends to the axle housing 42 supported on the drive wheels 43. rI he engine 44' is carried by the bars 41 and drives the,traction wlieels 43- through the transmission 44* and chain 44h. rlhe operating parts of the implement are driven from a power take-ofi'. shaft 44 which is driven from the transmissionas shown in my co-pending Patent No. 1,301,811. A rearwardly extending draft bar 45 is secured to the draw bar or axle housing 42 and is supported laterally by the diagonal brace 46. Secured to the front ends of the frame members 1 and 2 of what may be termed the initial or tractor unit of the machine, is a gear frame member 47 carrying bearing boxes 48, in which is journaled a cross shaft I 49, upon which is journaled a sprocket wheel 50 that may be operatively oo nnected with a moving part of the tractor mechanism, as, by means of a driving chain 51. 52 repre sents a slidable clutch member secured to the shaft in a manner to ltransmit rotation thereto and adapted to normally engage with the sprocket wheel 5() under the reactive force of a coiled compression sprin 53 encircling the shaft and operative tween one of the bearing boxes 48 and the slidable clutch member, and 54 represents aclutch shipping lever pivotally mounted upon the gear frame and operative to control the position of the slidable clutch member. The grassward end of the cross shaft 49 is operatively connected with the adjacent end of the shaft 7 by means of a universal coupling mechanism 55. The front end of the frame o f the tractor unit carrying the gear frame member 47 is pivotally connected with the rear end ofthe draft bar 45, and 56 represents a supplemental draft bar disposed parallel with the bar 45 and connecting the opposite end of the draw bar 42 with the frame of the tractor unit in a manner to rigidly connect it with the tractor when it is in -an operative position and moving forward' or turning at the corners, the rear end of this supplemental draft bar being so connected to the frame of the trac-` tor unit frame that the latter may' swing to a trailing position, as shown by dotted lines in Figure 1. 57 represents a chain connection between the frame of the 'mower section and the tractor adapted to sustain the weight of the mower frame The second. mower unit is substantially the same as the tractor unit without the gear frame member 47, and the frame bars 1 and 2 are connected by means of a joining member 58, the opposite ends of the driving shaft l1 operatively engagingv with the coupling sleeves 10 in a manner to transmit motion from the tractor ljunit to the second unit; 60 represents a bracket member secured-to the rear end of the frame bars 1 and 2y of the second unit, and provided with a vertically disposed sleeve 61, in which is journaled the vertical stem of a caster wheel supporting arm 62, having a wheels63 journaled upon its lower laterally turned axle member 64. 'The machine may include' as manyl units as desired, one, two, three, or more units like the second, if desirable, being con.- lnected b means of joining members 58, the caster w eel supporting arm being in each case preferably secured to the g'rassward ends of the frame bars of the rear unit. Obviously, b'y suitably proportioning the joining members 58 and the slidable power connections, units having cutter bars of diderent lengths may also be used if desired. -The coupled units form a continuous rigid frame in lineal relation that, is'carried as one piece with the tractor and is bodily removable, if desired. A single source of power transmits motion to the several cutting units. The cutter bars are free to rise and fall and be tilted independently, and are spaced apart in the direction of the line of draft suiiiciently .to permit the cut grass from` the drive sprocket on the shaft .42@ frame member 47 about the pivotal` Of course, when in cutting position, the vpower connections may be controlled by Athe 1ever'54. Y Having shown and described one embodiment of my invention, I do notl wish that it be confined to the s ecific details of construction, it being un erstood that changes may be made in lthe organization and proortion of its parte, for example, as shown in the patent granted to me January 14, Y 1919 No. 1,291,393, without departing from the s irit and scope of the invention as'indi- 130 cate in the appended claims.
