IMPROVEMENT IN HORSE HAY-RAKES.

The Schedule referred to in these Letters Patent and making part ol the same To au whom it may concern:

Be it known that Munras Ranzen, of i Reading, in the county of` Berks and State of-Pennsylvania, did invent certain new and useful Improvement-s in Horse Hay-Rakes, of which the foliowing is a full, clear, and exact description, referencebeing had to the accompanying drawings forming a part of this speeication, in which- Figure 1 represents a plan or top view of his said improved horse hay-rake, the shafts being shown broken o;

Figure 2 represents a rear view;

Figure 3 represents a section on line A B, tig. 1;

Figure 4 represents a-section on line C I), fig. 1

Figure 5 represents in dark lines a section on line E F,'fig. 1, and in blue and red lines some ofthe partsin ditierent positions; and

Figure 6 represents a perspective view of one of the eye-bolts, and the upper part of one of the teeth, as will be hereafter explained.

To enable those skilled in the art to which the said RAEZEBS invention belongs to make and use the same, I will describe it more in detail.

The nature of the invention consists- First, intheJ` combination,in a two-wheeled horse hay-rake, with a series of curved wire teeth, hinged or connected at their upper forward ends by yielding joints,`of la series of independent self-adjusting guides, upon which are arranged yielding springs, substantially as hereaftenset forth.

Second, in the arrangement, in a two-wheeled horse hay-rake, of a series of curved gathering-teeth and separate detachable eye-bolts, b, with a gained or grooved rake-head, whereby either one of the teeth can be easily disconnected or connected with the head by partially nnscrewing the nut of the eye-bolt, substantially as hereafter described.

Third, in the arrangement, with the rake-head and slide-bar, located upon the platform, and provided with cog-teeth, of a hand-lever provided with cog-teeth, hinged connecting-piece, footilever provided with projections, and foot-pad and spring, all as hereafter set forth.

Fourth, in the combination, with the rake-head and rake-teeth, of independent guides, guide-springs, and

cross-spring bar, with depressing-springs, substantially as hereafter described.

In the drawingsl A is the platform, which is secured to' the rear ends of the shafts B B, fastened to the axle Q, which is 'supported by the wheels D D;

Fastened to each end of axle C, and projecting back and up, are two bearing or hanger-pieces, E E, in the upper endsot` which the journals of Vthe` rakefhcad F are supported, while in their. lo\vcr ends the journals ofthe bar G, to which the clearer-fingers are attached,

are supported.

The 'front side ofthe rake-head is vertically grooved or gained out, to receive the upper ends of the teeth H, and prevent thern froml having too much lateral play.

The teeth l.' are simply curved, with eyes a attheir upper ends, to receive the hooked ends of the'eyebolts b, the shanks of which pass through the head F, and are secured in place by nuts c, as fully indicated in the drawings.

By this mode of connecting the teeth with the head, they are free to rise, in consequence of their hinged or jointed connections with the head, while they can be detached from the head by simply removing the eyebolts, so as to slip their eyes off of the hookedfends of the same.

It will be observed that the gains or grooves in the head F, being back of the point where the teeth are secured to the head, will prevent the teeth' from lia/ving too much lateral play when their lower ends are raised or forced back, as shown in blue lines, by coniing in contact with obstructions.

As the gains or grooves are moved with the teeth when they are raised to discharge the hay, the teeth are not liable to derangeinent, or to be thrown out of their respective grooves or gains, either during the operation of raking or discharging the hay.

To give the teeth elasticity, and, at the Sametime, to hold and sustain them against back strain during the `peration of raking, they are passed through oblong holes or slots in the lower ends of guides d, the

upper ends of guides d being provided with coiled or spiral-wire springs e, the lower ends of thc'j resting upon the shoulders -1 of the guides the upper ends of the Springs press upv ag'ai he under side of the cross-springl bar I, through which the upper ends of guides d pass, and are free to slide or move therein.

Bar I is arranged parallel to the-rakefhead and is provided at each end wit-l1 a piu or.stl 1: said studs being tit-ted to work up and dowriifreelyjn holes in ings the ends g of the'bcut arms h, which are secured to the rake-head, so as to turn with it.

Upon the studs ff are placed spiral or coiled-wire springs 2, whereby the elasticity off-'the -teeth is rendered still greater. Y

Upon the ends of the rake-head areseeured segment-gears J J, the teeth of which mesh iuto. similar teeth or cogs on segment-gears 3 3 on the .ends of the rock-shaft or bar G, to which the clearer-fingers'K are attached.

To the top vof the rakelxead is fastened an arm, fm, which is coupled with'the rear end of' th'esliding. draft-- bar L by mea-ns of thc connection-nn tomatic locking-lever 0. One end, 9, of said lever projects up through the platform, and is provided with a spring, 10, which presses up against the foot-pad '1l on the extreme upper end of lever O, while a lookin arm or projection, 12, on the center (f said lever, passes up through theplatforni, and entersa notch in the lower side of the slide-piece L.

The object of the locking-arm 12 is to hold` the teeth and head' from being turned forward by the 'resistance of the hay while being gathered, or from-being prematurely opera-ted by the horse. i

vBy arranging the drivcrs seat npon the left-hand side of the rake, andthe mechanism for elevating the rake-teeth near the middle or center, several advantages are obtained, among which maybe mentioned the following z' First. The posit-ion of the driver is such that he can see obstructions which may be in the path, or Vforward ofthe horse, and thus be able to avoid them by turning tothe rightv or left before they are struck by the rake-teeth.

Second. By the arrangement of the teeth and headoperating mechanism near the center of the rake, there is less straining of the parts, and less liability of springing the head. Besides, the hand head-operating lever, being at the right of the driver, is not liable to interfere with the drivers limbs.

ln iig. 5, the relative position of the rake-head, teeth, and clearing-fingers are shown in red lines as they appear when the raked hay is being discharged, While the elasticity or yielding capacity of the teeth ieated in `blne lines,

, ground While lthe rake .is in operation, thus preventing the head from turning back, as well as from turning forward, while gathering the hay.

Having-thus described thel improvements of the' said MA'rnrAs Ranzen in horse hay-mires,

What I' claim as the invention of said Marinas Ranzen., and ydesire to have secured by Letters Patent,"is-' `1..'Ihe combination, in a two-wheeled horse hayrake, with a series of curved-wire teeth, hinged or connected at their forward upper ends by yielding yjoints, of a series of independent self-adjusting guides,

upon which are arranged yielding springs, substantiallyT as set forth.

2. The arrangement, in a two-wheeled horse hayrake, of a series "of curved gathering-teeth, H, and

separate detachableVeye-bolts 71,'with a'gained or` grooved rake-bead, F, whereby either one ofthe teeth can beeasily disconnected or connected with the hea-d' by partially unscrewing the nut "of the eye-bolt, 'sub stantially as described..

3. The arrangement, witlrthe rake-head F and slidebar L, located upon the platform A, and provided with cog-teeth, of a hand-lever, M, provided with cog-teeth, hinged connecting-piece n, foot-lever 0, provided with projections 9 and l2, foot-pad l1', and spring 10, said part-s being arranged, in relation to each other, sub- Y stantially as described.

4. The combination, with the rake-head1, teeth H, guides (l, and springs e, of' cross-spring bar I, with its depressiiig-springs, substantially as described.
