DIVISION No. 2.

To all 'whom 'it may co'ncern:

Be it known that HARVEY W. SABIN, late of (Janandaigua, 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 of 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 extendled for the term of seven years from and after the expiration of the first term-viz., from December 3,-1864-and which patent so extended was, on .the 5th day of December, 1864, duly assigned to CHARLES MAsoN, ROBERT W. FENWICK, and DE WI'rr O. LAWRENCE, of Washington city, in the District of Columbia; and we, the said CHARLES MAsoN, ROB- ERT W.'FENW1CK, and DEWITT C. LAWRENCE, do hereby declare that the following is a full, clear, and exact description of the construction of that part of the invention which We designate an Arrangement of Articulatin'g (Jontrivances7 which have their support directly upon the axle of the rake-carriage, reference being had to the aceolnpanying' drawings, forminga part of this specification, in which- Figure 1 is a Vertical longitudinal section of the rake as it appears when the teeth are in raking position. Fig. 2 is a section similar to Fig. 1, and shows the teeth when in discharging position. Fig. 3 is a perspective view of a portion, of the rake as it appears when in raking position. Fig.v4 is a detail view, and Fig. 5 a plan or top view, of a rake complete with the invention applied to it.

Similar letters of reference in the several fi gure's indicate corresponding parts.

The nature of the invention covered by this patent consists, first, in arranging rake-teeth directly on the axle of the carriage-wheels and so that they can articulate upon said axle; second, in arranging an oscillating bar for raisin g rake-teeth directly on the axle ofthe carriage- Wheels and so that it can articulate on said axle; third, in arranging an oscillating bar for exerting pressure upon rake-teeth upon the axle of the carriage-wheels and so that it' can articulate on said axle as its center of motion; fourth, in arrangin g an oscillating lever or levers directly on the axle of the carriage-wheels' and so that 'it or they can articulate on said axle; fifth, it consists in arranging a clearer to rake-teeth directly on the axle of 'the cari'iage-wheels and so that it can artieulate on said axle, the axle extending entirely across the carriage-frame, as will be hereinafter described.

By means ofthe invention above stated the necessity for using a separate shaft for any or all of the several elements named is avoided, and thus the construction of the rake is simplified and cheapened. Besides this, the tubular eye-bearings of the raka-teeth and of the other named elements of the rake are made available for strengthenin g .the carriage-ax'le, and thus simplicity and cheapnesswith durability are secured.

To enable others skilled in the art to make and use this invention, we will proceed to describe the same, with reference to the drawings.

In the accompanying drawings, A is the carriage and supporting axle; B B, two transporting-wheels, one of which is made fast upon the axle, so as to rotate with it.

O O are thills or shafts.- They are extended back upon and beyond the axle 'A, and by means of tubular bearings a a are connected to the same in such manner that they are free to turn independently of the axle. On the rear extensions of the thills a transverse bar or rod, K, is arranged, and at some distance forward of the axle A a cross-piece, F', is applied tothem, so as to brace them and afford a means for attaching the sin gle-tree to which the horse is harnessed. The bar K serves to -support all the reke-teeth at a proper raking a' a', which allow the teeth freedom to articulate independently of the axle while raking or discharging the hay.v The eye-bearings are of tubular form and much longer than the width of the teeth, and they are slipped upon the axle A in such manner that they abut against one another, and thus serve to stay the axle, while they serve as lateral braces and supports to the teeth, which are narrow and arranged at some distance apart, as represented. The teeth attachto the top of the bearings a' a', and extend therefrom forward and upward, as shown at d' d'. the teeth is such that it insures theproper ele- Vation of the raking ends of the teeth for the clearing of the gathered hay therefrom.

Upon the axle A is loosely'fitted an oscillating and sliding disk or wheel, Gr, in the face of which a series of pins, b b, are set, so as to form a circle; and from or near the circumference of the said disk a singlelifting-pin, d, extends in a direction at right angles to the pins b b, as represented. This disk also has a grooved collar, y, formed on it, and the same' is loosely encircled or clasped by a clutch-lever, I, which is pivoted orvfulcrumed at e on one of the thills, and therefrom extended to a point convenient for the attendant to lay hold of and move it in a horilzontal direction whenever it is desirable to couple the rake with the axle A. Near and opposite that face of the disk in which the pins I) b are set a couplingpin, c, projects from the axle, so as to stand opposite a space between one or another pair of the pins b. Said pin c and' the pins b b serve as a means whereby the axle and disk can be geared together, and thus both turn together. To effect this gearing togther of these parts,it is only necessary to lay hold of the clutch-lever I and move it in such a' dirsction as will cause the disk to slide on the axle toward the pin c, this movement bringing one or another pair of the pins b b in such a position with respect to the pin c that said pin c will stand between them, and therefore when the axle is moved it carries the disk with it. It is evident from the foregoing that the lever I with the disk G artieulate about the axle A as a centerV of motion.

E represents what may be termed a tilting frame, and F an oscillating pressureframe. The tilting frame E is jointed loosely on the axle A, near the whcels B B, by means of tubular boxes or sleeves w w, to which it is rigidly fastened, while the pressure-frame F is loosely jointed upon said sleeves or boxes a: w by means of coils z z on the te'rmini of the said bars. Thus attached or connected to the axle A, the frame E is free to turn or oscillate independently of the axle and of the frame F, while the frame F is free to turn or oscillate independently of both the axle and the frame E. The transverse bar of the frame E rests against the upper side of the forward extensions of the teeth, while the transverse bar of the frame F rests down upon the teeth in rear of the axle A. From the foregoing it is evi- This forward extension of dent that the tilting frame and the pressure- J is a hand-lever fastened to a hub, S, of

-the oscillating disk. This lever articulates with the disk Gr directly on' the axle A, and it extends to a convenient point over the transverse bar of the frame F, to be controlled by the attendaut of the machine. By means of this lever the attendant can, when necessary or at will, exert any required .pressure upon the transverse bar of the frame F, and thus keep all of the metallic spring-teeth to their work; or with it all of the teeth, when necessary to clear formidable obstructions, may be thrown up and again allowed to fall back to their raking positions, for by moving the lever upward when the axle is not in gear with itthe disk will move with it and the liftingpin d caused to press down against the front or tilting frame, E, and said frame thereby caused -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, and therefore the gathered hay upon the teeth may at the will of the operator be discharged either by manual or horse power, and to make the -rake self-ungearing and capable of resetting itself when horse-power for discharging the gathered hay is employed, the inclined trip H is attached to one of the thills in such relation to the tripping-pin d of the disk G 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 or power of the team the said lifting-pin will come in contact with this trip H and at the proper moment cause the disk to slide laterally on the axle and release its pins b from the coupling-pin c, and thus allow the frames E and F,.with the disk, raketeeth, and hand-lever J, to go back or reset themselves in their original positions, ready for gathering a fresh load. The length of the pins b and the form of the trip H are such that the pin d will be tripped when the rake-teeth have risen high enough to have the hay cleared from them by the rod or bar K.

The contrivauces for enabling the draft of the team to discharge the gathered hay and the rake to reset itself are not claimed under this patent, as they are embraced in Division No. 1 of this reissue. i

We have clearly shown that all of the main elements of the rake are supported upon and' allowed freedom to artioulate on the carria geaxle; and it is evident that this arrangement of the same saves the expense of an extra sh aft for their support, which is an item of some importance in the manufacture of rakes. Besides this, the rake is light and durable.

What we claim as new, and desire to secure by Letters Patent of the United States, is'- 1. Arranging rake-teeth directly on the axle of the carriage-wheels and so that they can articulate upon said axle, for the purpose set forth.

2. Arranging an oscillating bar for raising on said axle as its center of motion, for the purpose set forth.

4. Arrauging an oscillating pressure-level' or a coupling'lever on the axle of the carriage- Wheels and so that either or both can articulate on said axle, for the purpose set forth. I

5. Arranging a clearer to rakc-teeth directly upon the axle ,of the carriage-wheels, said axle oxtending entirely across the carriage-frame. and so that it can articulate or oseillate on said axle, for the purpose set forth.
