IMPROVEMENT |N HARVESTERS.

Specification forming part of Letters Patent No. 1,803, dated July 9, 1861 reissue No. 2,454, dated January 15, 1867.

To all whom it may concern:

Be it known that McGLrNToeK YOUNG, Jr., of Frederick, in the county of Frederick and State of Maryland, did invent certain new and useful Improvements in Harvesting-Machines and that the following is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, making a part of this specification, in which- Figure 1 represents in perspective so much of a harvesting-machine as illustrates the invention of said MeOLINTocK YOUNG, Jr. Fig.

' 2 represents a top plan, and Fig. 3 asectional elevation, of the same.

Similar letters of reference where they occur in the separate figures denote like parts of the machine in all drawing.

The invention relates to the combination of an automatic rake with a combined reaping and mowing machine; or, in other words, to a harvestin g=machine havin ga hinged joint, and also capable of being converted intoa reaping or mowing machine, as the case may be 5 and it consists in the manner of connecting the platform and cutting apparatus with the main frame, so that they may rise and fall in conforming to the surface of the ground independent of each other; and also, in combination with the platform and main frame of a hingedbar machine, a rake and rakedriving mechanism that will permit the rising and falling of the platform, and yet retain the position of the working parts to the platform and it consists, lastly, in making the finger-bar in two sections of different lengths, the long section being attached to the main frame, and the short section to the platform, so that when the platform is removed to convert the machine intoa grassmower the finger-bar shall be shortened in length to the extent of the Vshort section attached to the platform.

To enable others skilled in the art to make and use the invention of said MCCLINTOOK YOUNG, Jr., the following description of the same, in connection with the drawin gs, is given.

A B represent two supporting-wheels on an axle, C, the wheel B being fast on the axle, so as to make it a drive-wheel also. O'n the axle G is supported a frame, D, to which the tongue E is attached, and the tongue E, at or about the point a thereon, is connected, by a shackle or link connection, I), Fig. 3, to a beam, F, that passes underneath the axle C and thence rearward, to support the platform, cutting apparatus, rake, and rake-driving mechanism, as will be explained. A brace, c, extends upward from the beam F, which passes up through a notch, mortise, or guide on the main frame l), so as to keep this beam in line while it or the main frame are free to move vertically as the ground'over which they are passing may demand. The plat-form G is fastened to a platform beam or support, H,which is oblique to and .behind the Enger-bar, and at the outer end of this support is the outside supporting-wheel I, Fig. 2. The finger-bar is made in two sec tions, J 'and J', the one J, which is much the larger one, being secured to the beam F, and the short section J tothe platform G; the object of this being to have a short finger-bar and cutter when mowing, and a longer one when reaping, and to make the change without removing or detaching the finger-bar from the main frame to apply another in its place. On the end ofthe platform-beam H, next the stubble, there is apillar-blockbox,K, in which the journal of a bevel-wheel, L, is supported and turns, and upon this pillar-support K there is a horizontal arm-support, O, on which, as a journal and slide, the bevel-pinion M is connected, by a gimhal-joint, as at d, Fig. l, an end of a drivin g-shaft, N, the other end whereof is supported in a bearing-block, O, upon the projected end of the axle o and the extreme end of the shaft N has a bevel-pinion, P, upon it, which is turned by the bevelwheel Q on the axle C. This arrangement of driving-gear, though shown outside of the supporting-wheel A, may be put inside, -or between the wheels A B. The bevel-pinion M turns the bevelwheel L; and on top of this wheel L is pivoted the rake-shank R, to which the rakes S S are connected, and by which they are rotated. T is a cam-ledge, under which hooks orarmse on the rake-stocks take to draw the rakes down to, and make them traverse close over, the platform, the one going down raising up its fellow high enough to pass over the wheels, and then drop onto, or close to, the platform.

for holding itself, in connection with the screw f to the beam F. Where the sections of the iinger-bar butt together there may be any suitable kind of fastening to keep them together, and in line. For cutting grain the finger-bar and cutters maybe from five to six feet in length; but for grass a four feet swath, or four and a haltl feet, is found to be enough,

land for this object the linger-bar is made in sections.

Having thus fully described the invention of said McCLIN'roK YOUNG, Jr., what is claimed is- 1. Driving an automatic rake on a twowheel hinged-bar machine by mechanism located outside of the wheels instead of between the wheels.

2. Locating the vertical axle of an automatic revolving rake upon the platform ofa harvester at or near its inner front corner.

3. Driving' an automatic rake located on the platform of a two-wheel hinged-bar machinev by means of a jointed tumbling-shaftl driven from the end of the main axle.

4. rIhe combination of a hinged platform with an automatic rake located at or near its innerfront corner.

5. In a oating linger-bar machine the combination of a revolving rake and reel, supported wholly upon the platform at or near its inner front corner in a removable frame,.

so that said machine can be readily converted from'a mower to an automatic reaper, and v1ce versa. l

6. In a hinged finger-bar machine, rigidly connectingl the rake-frame to the platform on which it is supported in such a manner that the rake-shaft does not change its relative position to the platform in passing over uneven ground.

7. Attaching the revolving rake and reelarm directly to the upper side of the crown or bevel-wheel, by which they are driven.

8. Locating the crown or bevel-wheel, to which the arms of the revolving rake or reel are attached, below the top of the drivingwheel. V l

9. Combining a segmental cam or guide with a series ot' rake and reel arms, so attached together in pairs diametrically that while one rake is moving in contact with the grain its opposite arm shall be thrown up to any desired extent to clear the driving-wheel and main frame.

10. Arranging the shaft, which drives the revolving rake and reel, located on the platform of a ioating finger cutting apparatus, in such a manner that the said shaft shall vibrate around the main shaft as a center, when the cutting apparatus is raised and lowered.

11. The construction'and adaptation of a combined rake and reel, which revolves entirely around a vertical center, so that the revolving rake and reel arms may be attached to the driving hub or highest point of said wheel.

l2. The combination of a revolving rake and i reel, and a hinged-bar machine, when the arms of said revolving rake and reel are attached together to the head at such an angle as in their revolution to be thrown up, so as to leave an unobstructed space on the machine.

13. Attaching the frame or support of the continually-revolving rake to the removable platform, so that the entire rake apparatus can be removed with the platform for converting the machine from a reaper to a mower.

14. Driving the continuonsly-revolving rakearms bythe upper surface of a crown-wheel, in combination with supportingthat crownwheel on top of a vert-ical standard, and attaching to the same vertical standard ahorizontal stud, on which the driving pinion revolves.

15. A rake rotating upon an axis which is perpendicular to thetop surface of the platform, and having vits arms .successivelyelevated, substantially as and for Vthe purpose described.

16. A standard or support which sustains the sweep-rake above the draft-trame or driving-wheel, said standard being mounted wholl y upon the platform of the hinged machine and below the top of the driving-wheel.

17. Making a finger-bar in two sections, 011e long and one short, the short section being connected to the platform and removable with it, so that as the platform is attached to adapt the machine-for harvesting grain, or removed to adapt it to the cutting of grass, the fingerbar shall be correspondingly lengthened and shortened, as has been found advantageous in harvesting the different materials, substan` tially as described.
