LEROY SPENCER, OF ISLAND CITY, OREGON.

" HARVESTER;

SPECIFICATION formingpart of Letters Patent No. 742,078, dated October 20, 1905 Application filed April 18, 1903. Serial No. 153,277. (No modelal T0 allwhom it may concern.-

Be it known that I, LEROY SPENCER, a citizen of the United States, residing at Island City, in the county of Union and State of Oregon, have invented a new and useful Harvester, of which the following is a specification.

This invention relates to thatclass of grainharvesters which are known as headers and which in practice are operated by a team or teams.pushing the same. In this class of devices as usually constructed the headerplatform in order to enable the grain to be cut at Various height-s from the ground. according to theheight of the straw, has usually been hingedly connected with the frame of the machine in such a manner as to enable it to be tilted, thereby raising and lowering the cutting apparatus at the front edge of said them level at various heights of adjustment,

the means for efiecting such adjustment have usually been more or less crude and have frequently involved the necessity of tempo-- rarily supporting the table or platform and prying upward upon the same in order toenable the bolts or fastening means whereby connection has been made with the frame of the machine to be detached and readjusted. Such contrivances have always involved much less of time and have been of such a nature as to enable the requisite adjustment to be made by a single person practically ,im-' possible. V

My present invention has for its object to construct a header in which the vertical adjustment of the cutting table or platform may be effected in an extremely simple and convenient manner, in which the necessary adjustment may be effected by the driver without necessity of his leaving the platform upon which he is stationed, in which an elejustable grain table or platform.

vator is provided to carry off from the grain table or platform the heads of grain, said ele vator being suitably tilted and connected with the table or platform and with supporting means in such a manner that the tilt of the elevator shall not be affected by the rais ing or lowering of said table or platform, and, in short, to provide a device of the class referred to which shall possess superior advantages in point of simplicity, durability, and general efficiency.

With these and other. ends in view, which will appear as by the description of my invention the aim of the same is better understood, myinvention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of a harvesting-machine constructed in accordance with the principles of my invention, an intermediate portion of the pushbar and connecting-rods having been broken away. Fig. 2 is a longitudinal sectional detail view, on a larger scale, of the platform and the bracing means for the elevator. Fig. -7 is a perspective detail view of the supporting-frame for the vertically-addetail enlarged sectional view illustrating the construction of one of the bearings for the shaft of the outer roller supporting the endless carrier 71. Fig. 9 is a detail front ele- Fig.8isa.

Fig. 4 is a secvation showing the connection efthe elevator with the grain-platform. Fig. 10 is asectional detail view taken on the line 10 10 in Fig. 2, showing the vertical shaft and its related parts in elevation on a larger scale. Fig. 11 is a detail elevation of the rear side of the elevator, showing the housing and its related parts.

Corresponding parts in the several figures are indicated by similar numerals of referonce.

The main frame of my improved header may be described as consisting of the axle 1, the tongue or push-bar 2, and a brace 3, conmeeting the latter with the axle. It will be observed that the tongue 2 is connected with the axle 1 near one end of the latter at a short distance from the bull-wheel4, while the connection of the brace 3 with the axle is at no greatdistance from the opposite end of the latter adjacent to the inner side of the supporting-wheel 5. The connections between the axle, the tongue, and the brace may be effected in any suitable manner whereby the said parts shall be rigidly connected, so as to form a stiff and durable frame structure.

Closely adjacent to the inner sides of the wheels 4 and 5 the axle supports a pair of triangular frame structures 6 and 7, which latter is adjacent to the bull-wheel4. These frame structu res, or brackets, as they may be properly termed, may be supported from and connected with the axle by means of clips or in any other suitable and convenient manner. These frames, or brackets, as I prefer to term them, are provided with forwardlyextending arms 9, the front ends of which are in perpendicular alinement with the rear ends of a pair of truss-bars 10, extending downwardly and forwardly from the rear ends of the brackets 6 and 7. The front ends of the arms 9 and the truss-bars 10 support a pair of uprights 11, at the upper ends of which pulleys 12 are supported.

The bracket members 6 and 7at the upper corners thereof afford bearings fora shaft 14, which is disposed above and parallel to the axle of the machine. This shaft carries a bevel gear 15, meshing with a pinion 16, mounted upon the front end of alongitudinal shaft 17, the latter having its bearings in uprights 18 and 19, rising from the tongue or push-bar 2. The upright 18 is a simple standard supported upon the tongue at a point close to its junction with the axle. The upright 191s disposed directly in front of the drivers stand 20, which is supported upon the push-bar near the rear end of the latter. The extreme rear end of said push-bar is provided with a vertically-disposed yoke 21, affording bearings for a shank or spindle 22, the lower end of which is bifurcated, as shown at 23, to receive the ends of a shaft 24, carrying a trail-wheel 25, which, the shank or spindle 22 being swiveled, as described, will adapt itself to the machine when the latter is turning. It may also be used as a guide-wheel to direct the forward movementof the machine, the upper end of the shank or spindle 22 being provided with a handle 25,wherebyit may be adjusted, as will be readily understood. The brace-rod 27 connects the upright 19 with the tongue or push-bar. It will of course be understood that braces and connecting-rods of a like nature are to be used wherever their presence in the frame structure of the device may be deemed desirable or necessary.

The end of the axle which carries the bullwheel is provided with a horizontally-disposed frame structure, comprising, essentially, an outer frame-bar 29, a rear bar 30, and an inner frame-bar 31, which latter is suitably connected with the front end of the bracket 7. The side members 29 and 31 are provided with bearings for a transverse shaft 32, carrying a sprocket-wheel 33, which is connected, by means of a chain 34, with a sprocket-Wheel 35, which is suitably connected with the bullwheel, so as to revolve with the latter. The hub of the sprocket-wheel 33, which is loose upon the shaft 32, forms a clutch member 36, adapted to engage a sliding clutch member 37, which is feathered upon the shaft 32, so as to revolve with the latter. The slidable clutch member 37 is normally held in engagement with the clutch 36 of the sprocket-wheel 33 by means of a spring 38, coiled upon the shaft and forcing the said slidable clutch member in the direction of the sprocket-wheel. The slidable clutch member 37 is provided with an annular groove 39, engaged by a bifurcated rod or arm 40, which is transversely slidable upon the rock-shaft 41, mounted in suitable bearings in rear of the shaft 32. The hub or sleeve 42, by means of which the arm 40 slides upon the rock-shaft 41, is provided with inclined notches 43, adapted to be engaged by a clutch member 44, mounted securely upon the rock-shaft 41. The latter is provided at one end with a crank 45, with which is pivotally connected a rod orlink 46, extending to the front upright 19, supported upon the tongue or push-bar, where it is supported slidably in a loop or staple 47. The end of the connecting-rod 46 thus disposed within the reach of the driver is provided with a handle 43, whereby it may be conveniently operated by the driver, so as to oscillate the rock-shaft, thereby causing the clutch member 44 to operate against the notched sleeve 42 of the arm 40, thus causing the latter to slide in an outward direction. \Vhen thus operated, the arm 40 by its bifurcated front end engaging the slidable clutch member 39 will force the latter in an outward direction, thereby releasing it from engagement with the clutch member upon the hub of the sprocket-wheel 33, which latter will thus rotate freely upon the shaft 32 without communicating motion to the latter. It will be understood that mechanism, to be hereinafterdescribed,is driven from the shaft 32; hence the necessity for the presence of the mechanism just described for throwing such driven parts of the machine into and out of gear, as may be required.

49 designates the grain-table or cutter-platform,which is supported upon a pairof braces 50, provided with upwardly-extending pairs of arms 51, the upper ends of which have rearwardly-extending brackets 52. Rollers 53 and 54 are journaled between the arms 51 and the brackets 52,said rollers being adapted.

connected by a cross bar or brace 55, which extends through the said pairs of arms, thereby preventing accidental dislocation of any of the parts. Suitably connected with the ends of the brace 55 are flexible connecting members, such as cords or chains 56, which pass over the pulleys 12 at the upper ends of the uprights 11 and are made fast to the peripheries of grooved wheels or drums 57, suitably secured upon the shaft 14, which has been hereinbefore described.

It will'thus be seen that by rotating the shaft 17 in its bearings the pinion 16,engaging the bevel-gear 15,will thereby rotate the shaft 14, together with the drums 57, upon said shaft, thereby winding the cords or flexible connections 56, which, being made fast to the cross-brace 55, will raise or lift the supporting devices of the grain table or platform 49, which will thereby be bodily'elevated in a horizontal position to anydesired height within the limits of the parts of the device, particularly the uprights 11. This operation of adjusting the grain table or platform may be performed by the driver with-,

out necessity of his leaving his station, and the parts may be retained at their adjusted position by means of a ratchet-whee158 upon the front end of the shaft 17, said ratchetwheel being engaged by a vertically-sliding pawl 59, which is connected by means of a rod with a spring-actuated treadle 61. The shaft 17 is alsoprovided with a crank 62, by means of which it may be conveniently operated by the driver. When the shaft 17 is rotated in the proper direction to elevate the ratchet-Wheel by the driver stepping upon the treadle 61, when the grain table orplatform will drop by its own weight, the dropping, however, being restrained by the driver,

who retains his hold upon the crank 62, thereby preventing a too sudden drop, which might result injuriously to the machine.

The braces 50, which support the graiutable 49, are extended rearwardly of the uprights or arms 51 and are connected withthe latter by means of inclined braces 63 for the purpose of strengthening the parts. The

of the machine. I g

The grain table or platform 49 is provided at its front and rear edges with flanges 65 and 66, and at the front edge is suitably disposed a cutting apparatus comprising a'finger-bar 64 and a reciprocating cutter or sickle bar 68, which are of the conventional pattern. Rol1 ers69 and 70 are provided at the ends of the platform, said rollers supporting an endless apron or carrier 71, which is kept taut by the roller 69 at the inner end of the platform being mounted in slidable spring-pressed boxes 7 2, the construction and arrangement of which are well understood. The shaft of the roller 70 is provided at its front end with a crankdisk 73, thewrist or crank 74 of which is connected by a pitman 75 with the sickle-bar or 79, which is connected by a knuckle-joint parts, will be largely optional with the builder The roller 70 or with a short shaft 81, which is journaled in a suitable box or bearing 82 of the frame member 29, supported upon the outer end of the axle. The shaft 81 carries at its rear end a pinion 83, meshing with a bevel-gear 84 upon the shaft 32, from which motion is therebytransmitted not only to the cutting mechanism, but also to the endless apron or carrier 71.

The outer end of the grain table or platforni is provided with ears or brackets 85, affording bearings for the shaft 86 'of a roller 87, which is also journaled in bearings more lower ends of the sides of an elevator-frame 88, which latter may thus be described as being pivotally mounted .upon the roller-shaft 86, while the roller 87 may be properly described as being located at the lowerend of said elevator-frame. The latter extends outwardly and upwardly from the grain-table and is provided at its upper end with a roller 89. A slatted endless carrier 90 passes over and is supported upon the rollers 87 and 89, as will be.seen.- The general construction of the elevator-frame is of as simple and lighta nature as is compatible with the requisite strength, and the discharge end of said elevator is retained at a suitable tilt by means which are to be hereinafter described. For the purpose heads from being thrown rearwardly over the grain-table. The uprights 94 are provided with forwardly-extending brackets 97, which are to be suitably braced, if desired, and which support the shaft 98 of the reel 99, which is mounted to rotate in suitably-constructed boxes or bearings 100. I

101 designates a short shaft which is journaled in suitable bearings in the frame member 29 and in a brace or bracket 102, which latter is suitably connected with the frame of the machine. The shaft 101 carries a bevel-gear 103, meshing with a pinion 101, which is mounted upon a non-circular shaft 105, the lower end of which has a bearing in the boxing 106 of the shaft 101. To said boxing is secured an L-shaped bracket 107,which extends over the pinion 104 and restrains the latter against upward movement upon the shaft 105. The latter is extended upwardly and has a bearing in a bracket 108, which is suitably connected with one of the arms 97 of the vertically-movable grain-platform structure. Said arm 97 is also extended rearwardly and is provided at its rear end with a housing 109, containing a plurality of rollers 110 and 111, which engage the sides of the upright 1.12, which is rigidly secured to the outer end of the axle of the machine. The housing 109 is so constructed and the rollers 110 and 111 are so disposed therein that the said rollers 110 shall bear against the front of the upright 112, while the rollers 111 shall bear against the outer side of the latter, thereby assisting in supporting'the weight of the elevator-frame, as will be presentlyanore fully set forth. From the rear end of the arm 97 extends in an upward and forward direction an inclined derrick-beam 113, which is braced by suitably-disposed truss-bars 114, affording bearings for a short shaft 115, upon which is mounted a bevelgearllG, meshing with a pinion 117 upon the non-circular shaft 105, which latter is extended a suitable distance above the bracket 10S and an additional bracket 118, between which the said pinion is supported, thereby enabling the said pinion when the grain platform structure is raised or lowered to slide upwardly or downwardly upon the said noncircular shaft and to remain in operative connection with the latter. The periphery of the bevel-gear 116 is provided with sprocketteeth 119, connected, by means of a chain 120, with a sprocket-wheel 121 upon the shaft of the reel, to which motion is in this manner transmitted. It will be noticed that owing to the herein'described arrangement of the non-circular shaft, which is extended upwardly a sufficient distance to enable the pinion 117 to move thereon with the platformcarrying structure, motion will be transmitted to the reel in a perfectly steady manner which is not interrupted by the upward or downward movement of the platform-carrying structure.

The housing 109, which, as herein described,

is vertically movable upon the upright 112,

is provided with an outwardly extending brace 122, having at its outer end a horizon tally-disposed T-lug 123, said brace 122 being reinforced bya subbrace 124-. The rear side of the elevator-frame is provided with a segmental housing 125, the edges of which are provided with flanges 126, whereby the said housing is supported upon the rear side of said elevator-casing. The housing 25 has a segmental slot 127, which is engaged by the T-shaped lug 123 at the outer end of the brace-rod 122, so as to form a substantial support for the elevator structure at any tilt to which the latter may be adjusted. The said elevator-frame is thereby very securely supported and at the same time with a degree of flexibility, whereby injury to the working parts of the device will be avoided whether the machine be in transit or during opera tion. It is obvious, however, that additional support for the outer end of the elevator structure is necessary, and this is afforded by means of apulley-block 128, suitably connected with a bail 129, connecting the outer ends of the sides of the elevator and easing, the said pulley-block being connected, by means of tackle, with suitably-housed pulleys 130 at the outer end of the derrick-beam 113. One end of the rope or tackle 131 is made fast to the derrick-beam 113, after which it is reeved through the pulleys 128 and 130, as will be seen.

The frame of the machine supports in'rear of the axle 1 an upright bracket 132, which is suitably braced and supported and which is provided with bearings for a shaft 133-, carrying a grooved wheel or drum 134 and having also connected therewith a beveled pinion 135, that meshes with the bevel-gear 15 of the shaft 14. The upper end of the upright 132 has a bracket 136, in which is journaled a pulley 137, over which the free end of the rope or tackle is guided to the periphery of the grooved wheel or drum 134:, to which itis made fast.

It will appear from the foregoing description that when the shaft 17 is rotated to operate the bevel'gear 15 and the parts operated thereby, as herein described, it will at the same time transmit through said bevelgear 15 a rotary motion to the drum 13 1 through the pinion 135, which is mounted upon the same shaft as the said drum. Gonsequently when the grain -plaiform is elevated bythe mechanism herein described the said drum 134, being at the same time revolved or rotated, will serve to wind the rope or tackle 131, thereby shortening the connection between the derrick-beam 113 and the outer end of the elevator-casing in proportion as the latter is being raised. It is obvious that in the absence of such provision the raising or lowering of the grain-platform, assuming the elevator frame to be braced to the main structure of the machine, will result in the displacement of the said elevator-casing with relation to the grain-platform, and if, on the other hand, the elevator casing were braced to the verticallymovable platform structure it would impose upon the latter a side weight which would seriously interfere with the successful operation thereof. By my improved construction and arrangement of parts, however, the free end of the elevator-frame is braced to the main frame of the machine by the adjustable pulley-andtackle connection, whereby whether the platform structure be raised or lowered the elevator frame will retain substantially the same tilt with relation thereto. It is obvious that the amount of tilt of the elevator-frame may-be initially regulated by simply lengthening or shortening the rope or tackle.

The upright 94: at the inner rear corner of the grain table or platform is provided with braces 140 and 141, extending rearwardly from its lower and upper corners and carrying be tween their rear ends a pulley 142,which' rides upon an upright 143 at the inner end of the axle. This uprightis suitably braced,'so as to enable it to assist greatly in relieving the strain caused by the weight of the grain--- platform.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my improved heading-harvester will be readily understood. The general construction of said machine is simple and inexpensive, the adjustable parts of the device are capable of being governed and actuated by the driver without additional help or assistance, and my inventionpresents in a simple and compact form a durable, convenient, and easily operated machine for the purposes for which it is intended.
