DlvlsroN No. 1.

' lTo all whom it may concern.-

Be it known that HARVEY W. SABrN,late of Canandaigua, in the county of Ontario and State of New York, now deceased, was the originator of certain new and useful inventions and Improvements in Horse-Rakes, for which Letters Patent ot' the United States were granted him for the term of fourteen years from the 3d day of December, 1850, and that the said patent was duly renewed and extended for the term of seven years from and after the expiration of the iirst term-viz., from December 3, 18M-and which patent so extended was, on the 5th day of December, 1864, duly assigned to CHARLES MAsoN, ROB- ERT W. FENWICK, and DE WITT C. LAW- RENCE, of Washington city, in the District of Columbia; and we, the said CHARLES MAsoN, ROBERT W. FENWICK, and DE WITT C. LAW- RENGEdo hereby declare that the following is a full, clear, and exact description of that of the invention which effects the discharge of the gathered hay from the teeth of the rake, reference being had to the accompanying drawings and letters of reference marked thereon,v forming a part of this specication, in which- Figure I is a vertical transverse section of the rake through the axle of the carriage, look.-l

ing toward the rear of the rake. Fig. 2 is a plan or top view of the same. Figs. 3 and 4 are detail views ot' the same. Fig. 5 is a vertical longitudinal section of the rake as it appears when the teeth are in raking position. Fig. 6 is a section similar to Fig. 5, when the teeth are in a discharging position. Fig. 7 is aperspective view of a portion of the rake vas it appears when in raking position.

Similar letters of reference in the several figures indicate corresponding parts. l

This invention relates to that class of farming implements commonly known as horserakes, and which are used to gather hay or other like substances in windrows upon the field, preparatory to cockin g the same.

The nature of the invention covered by this patent consists in making such horse hayrakes as do not have their teeth to rotate with their shaft capable of discharging by the power of the team the hay which is gathered upon their teeth, such discharge being under control of the operator.

It also consists in making such horse hayrakes as are suspended or supported and propelled over the tield upon rotating wheels both capable of discharging their gathered load upon the ground by the draft of the team and of automatically resetting themselves to gather fresh loads.

Oscillating horse hay-rakes have not, previously to this invention, been constructed with a contrivance which enables the driver or manager, at will, to utilize the draft or power of the team to discharge the gathered loadofhay upon the ground. Neither have any description of horse hay-rakes mounted upon Wheels been capable of both discharging their gathered load of hay by the draft of the team and of resetting themselves automatically to gather fresh loads. f

To enable others skilled in the art to make and use this invention, we will proceed to give a description, with reference to the drawings, ot'one way in which the same may be done.

In the drawings, A isa rotating axle,andB B wheels for supporting it, one of which is made fast upon the axle, so as to rotate with it.

C C are thills or shafts. They are extended back upon and beyond the axle A, and, by means of articulating bearings aa, are connected to the same in such manner that the axle is free to revolve independently of them. On the rear extremities of the thills a trans- ,verse bar or rod, E,is arranged,and some distance forward of the axle A a cross-brace, F, is applied to them, so as to keep them apart and afford a means for attaching the singletree, to which the horseis harnessed. The bar E serves to support all the rake teeth at a proper raking relation to the ground, and it also serves the office of clearing the gathered hay from the rake-teeth when the rake is elevated for the purpose of discharging its load.

D D are rake-teeth, made of springy metal and of any approved style and shape, and connected to the axle by articulating eyebearings a a', which allow the axle freedom to rotate independently ofthe teeth, except at such times as it may be proper for the axle and teeth to move together. resented are of tubular form and much longer than the width of the teeth, and they are slipped upon the axle in such manner that they abut against one another, and thus serve as lateral supports between teeth which are narrow, and are arranged at some distance apart, as represented. These eye-bearings form no part of the invention claimed under this patent, they constituting the subjectmatter of another division of this reissue. The teeth ex- .tend forward and upward from the eye-bearings a' a', as shown at d cl,for a purpose presently described. This forward extension of the teeth should be on such an angle as will insure the proper elevation of the raking ends of the teeth for clearing the gathered hay therefrom.

Upon the axle A is loosely fitted an oscillating disk or wheel, F2, in the face of which a series of pins, g g, are set, so as tor form a circle, and from or near the circumference of the said disk a single liftingpin, h, extends in a direction at right angles to the pins g, as represented. This disk also has a grooved collar, y, formed on it, and the same is encircled or clasped by a clutch-lever, R, which is pivoted or fulcrumed at m on one of the thills, and therefrom extended back to a point convenient for the attendant to lay hold of and move it in a horizontal direction whenever it isnecessary to couple the rake with the axle. Near and opposite that face of the disk in which the pins g are set a coupling-pin, fw, projects from the'axle, so as to stand opposite a. space between one or another pair of the pins g. Said pin to and thepinsggserveas ameans whereby the axle and' disk can be geared together, and thus both turn together. To effect this gearing of the axle and disk it is only necessary to lay hold of the clutch-leverR and move it in such a direction as will cause the disk to slide on the axle toward the pin fw, this movement bringing one or another pair of the pins g in such a position with respect to the piu w that said pin w will stand between them, and therefore when the axle is moved it carries the disk with it.

G represents what may be termed a tiltingframe, and G apressure-frame. The front frame, G, isjoiuted loosely on the axle A, near the wheels B B, by means of tubular boxes or sleeves ma', to which it is rigidly fastened, while the rear frame, G', is'loosely jointed upon said sleeves or boxes m by means of coilsV z z on the termini of its side bars. Thus attached or connected to the axleA the frame G, is free to turn oroscillate independently of the axle and of the frame G', while the frame G' is free to oscillate independently of both the axle and the frame G. The respective frames G G consist of a transverse bar, long as the axle A, and two side bars, which run at right angles to the transverse portion and connect to the oscillating sleeves or boxes,

The eye-bearin gs repl which is nearly as' in the manner above described and herein represented. The transverse bar of the front frame, G, rests against the upper side of the forward extensions of the teeth, while the transverse bar of the rear frame, G', rests down upon the teeth in rear of the axle A. It will be observed that the side hars of therear frame, G', are longer than the side barsrof the front frame G, and by reason of this the rear frame, G', ha's the superior weight, which, in connection with the weight of the rear part of the teeth, insures a return of the parts to a raking position alter a gathered load has been discharged upon /the-ground. The frame G is allowed to articulate upon the axle in order that the tripping-pin h may move it around against the forward extensions of the teeth, and the frame G' is allowed to articulate on the sleeves or boxes ot' the frame G in order that it may turn and rise when it is necessary that one rake-tooth shall rise independently of theothers. Were it not for this independent articulation of the frame G', the teeth could not be elevated separately, but they would all be raised simultaneously, for any movement ot' the frame G' (if fastened rigidly to the sleeves or boxes) would be imparted to the sleeves or boxes, and from them to the frame G, and of course to the rake-teeth.

H is a hand-lever fastened to an open hub, S, of the oscillating disk. This lever extends to -a convenient point over the transverse bar of the frame G' to be controlled ,by the attendant of the machine. By means of this lever `the attendant can, when necessary, exert any y required pressure upon the transverse bar of the frame G', and thus keep all of the metallic spring-teeth to their Work, or with it all ot' the teeth, when -necessary to clear formidable obstructions, may be thrown up and again be brought back to their raking position, for by moving the lever upward the disk will be turned and the lifting-pin made to press against thefront tiltingframe, G, and said frame thereby made to elevate the raking ends of the teeth. To elevate the teeth by hand it is not necessary to couple the disk with the axle.

I is an inclined trip, attached to one of the thills in such relation to the lifting-pin h of the oscillating disk that after the disk has been set in gear with the axle and the rake is being elevated and its load discharged by the draft of the team the said lifting-pin will come in contact with it and at the proper moment cause the disk to slide laterally on the axle and release its pins g from the couplingpin fw, and thus allow the oscillating frames G G', with the disk, rake-teeth, and hand-lever, togo back or reset themselves in their original positions, ready for gathering a fresh load. VThe length of the pins g and the form of the trip I are such that the pin-l1l will be tripped when the rake-teeth .have risen high enough to have the hay cleared from them by `the rod or bar E. The pressure contrivance,

in connection with spring-teeth, applied so as to be under the control of the operator for applying o'r' producing the pressure upon the rake-teeth, constitutes the subject-matter for another division of this reissue, and therefore no claim is made in this patent on the same. There are also other features of invention herein described, upon which .the invention herein claimed does not depend for its successful operation, and upon such features of invention separate divisions or patents are applied for simultaneously with this.

Although we have given a general idea of the operation of the rake shown, it may be stated further that as soon as the rake-teeth have collected a load of hay the attendant takes hold of the lever R, and with it Amoves the clutch-disk F in gear with the couplingpin w of the'axle. This done and the axle being in motion from the draft of the team and the traction of .the driving-wheels, the axle and disk turn together, and the pin h, bearing against the front tilting frame, G, will depress the forward ends of the rake-teeth and cause the rear parts thereof, with the lever H and the rear oscillating pressure-frame, G2, to rise to a proper position for the discharge of the gathered load of hay. About the moment of the discharge of the' hay upon the ground the lifting-pin h becomes a releasing-pin by striking the incline trip I, and is with the disk slipped out of gear with the axle. At this stage the superior weight of the rear part of the rake over that of the forward part causes an instantaneous resetting of the whole for the gathering of a fresh load of hay.

Having described one practical mechanical contrivance for carrying out the invention herein described, we will state that we do not' limit ourselves to the particular construction and arrangement of devices shown and described, as it is obvious that the invention might be embodied in different forms without departing from the principle involved.

What we claim, and desire to secure by Letters Patent, is

1. An oscillating horse hay-rake which discharges its gathered load by the draft or power of the team, substantially as described.

2. A wheeled horse hay-rake both capable of discharging its gathered load upon the ground by the draft of the team and automatically resetting itself to gather a fresh load, substantially as described.

3. An oscillating horse-rake (the teeth of which do not rotate with their shaft) so constructed that its teeth may either be elevated by the draft ofthe team or by the attendant, substantially as described.
