Letters Patent No. 91,640, dated June 22, 1869.

IIVIPROV'EMENT IN HORSE-RAKES.

The lBollec'iule referred to in these Letters Patent and making partof the same.

lTo all 'whom it may concern.-

Be it known that I, WATSON KING, of Springfield, in the county of Sangamon, and State of Illinois, have invented certain new and useful Improvementsin Horse Hay-Rakes', and dohereby declare that the following is a full, clear, and' exact description of the same, reference beinghad to the accompanying drawings, making a part of this speoiiicati'on, in which- Figure 1 is a plan view of my improved rake;

Figure 2 is a central cross-sectiouon the line x x of g. l;

Figure 3 is a detached side elevation of the devices for revolving the axle;

Figure 4 is a top view of the same; and

Figure 5 isa broken longitudinal horizontal section l of the axle, showing the manner of securing the teeth therein. l

v Letters ofi likeY name and hind refer t0 lkplt each of the figures.

My invention relates to a class of' horse` hay-rakes, in which the teeth are secured to and revolve with the axle; and Y It consists, principallf/in the means employed for securing said teeth within lsaid axle, and also in the employment and arrangement of the devices for revolving said axle, as is fully set forth hereinafter.

In the annexed drawing- A represents the axle and rake-head, having pivotcd upon either end awheel, B, of the usual construction.

The shafts O Care secured to said axle by means of astra-p, c, passing around the same, so as to allow it to revolve freely within both wheels and straps.

D D, dto., represent the teeth, which are of the usual form, and are each secured to the rake-head or axle A by having their upper ends inserted within a transverse mortise, a, in said axle, and a wedge, d, driven into said mortise, so as to fill the same, and press said tooth firmly against its side.

In order that the teeth may not be accidentally withdrawn, and also. to enable them to retain the desired vertical position, the'upper end of each is extended through the mortise, and bent to one side, at a iight angle, d', so as to fit-into a longitudinal groove, a', in-

tersecting the forward ends of said mortises at a right angle, as shownfiniig. 5.

E represents a fianged ratchet-wheel, which is secured to the centre of the axle'. A ratchet-bar, F, resting upon andengaging with said wheel', is pivoted at its forward end to a lever,'G, which is, in turn, secured to a short shaft, H, working in suitable bearings attuched to the foot-board Upon the opposite end of said shaft is a curved handle, I, projecting upward, within convenient reach ofthe hand, so that by pressing said handle backward, the lever G is carried downwardand forward, and with it the ratoh et-bar F, revolvingr the ratchet-wheel E and rake-head A, and dumping the hay. l

Upon one of the anges of the ratchet-wheel is an angular toot-h, e, projecting upward and forward,`which engages with a stop, j', upon one side of the ratchetbar, said tooth and stop being so adjusted as to prevept the rake-head from revolving when the ratchetbaris thrown back, and the teeth of the rake are in the desired position for gathering the hay, as other- -wise said teeth would be carried backward, and raised from the ground as soon asY they commenced gathering the hay.

A rod, X, is seouredto the foot-board C, and projeoting to the rear, is caused to .pass over the ratchetwheel and bar, and hold the latter in place upon said wheel.

Said rod also serves as a stop to prevent the ratchet-bar from being drawn ltoo far forward, by engaging with a projection, ff upon l'the end "of said bar. i As the revolution of the rake-head, when. loaded,

would require the expenditure otconsidera-ble strength, provision is made for. assisting the driver in perform ing such operation.

A number of holes, x' z', 1is provided in the lever G, by means of which the 'single-tree is attached thereto, so that thev power necessary to draw the rake is appplied to the same through said lever.

As will -be seen by fig. 2, when the handle I is thrown forward, the lever G projeotsvto the rear, and slightly upward, so as to'bc nearly on a line with the draught, in which position it is so little affected by the force applied, as to be readily held i n position by placing the drivers foot upon the handle; but if said handie be allowedv to rise, so as to depress the rear end of said lever below the line of the draught, the power applied through the single-tree will be exerted in such a manner as to still further depress the rear end' 4of lsaid lever, and, by so doing, drawforward the ratchethar, and revolve the rake, dumping its load. y

It will be observed that when the handleis released, and while the lever G is drawn downward and forward, the forward motion ofthe wheels must cease, by which means the load is deposited with a certainty and-.ex-

actness that would be ilnpracticable if said, rake were moving forward and revolving at the same time, whereby all soattering ofthe hay is prevented, and the lsanne neatly placed in windrows, close to which the teeth can commence raking again.

Having thus fully lset forth the nature and merits of my invention,

What I claim as new, and desire to secure byrLetters Patent, is-

The combined axle and' rake-head A, provided with a series of transverse mortises, for the reception of the rake-teeth, and with a longitudinal groove intersecting said xnortises, for the reception ofthe ends of 2 said teeth, ysubstantially as and for the purpose speci- Also, the combination of the teeth D, provided with the angular endv d', mortise a, groove a', and wedged, substantially as andl for the purpose shown. Y Also, the devices for revolving the rake-head, oonsisting of the ratchet wheel E, ratchet-bar F, lever G, shaft H, and handle I, and iu combination therewith, the tooth e upon theiiange of the xatchet-wheel, stops f and f', upon the ratci1et-ba1,and rod x, substantially as shown, and for the purpose' described.
