SPECIFICATION forming part of Letters Patent No. 407,215, dated July 16, 1889.

Application filed May 5, 1888. Serial No. 272,952. (No model.)

To all whom, t may con/cern,.-

Beit known'that we, JOHN A. JOHNSON and NILs O. STARKS, both residents of Madison, in the county of Dane and State of Wisconsin, 5 have invented certain new and useful Improvem ents in Horse-Rakes 3 and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of t-his specification, and in which- Figure 1 is a side elevation of our improved horse-rake, one of the wheels havingI been removed and the teeth being shown elevated in dotted. lines.

Fig. L is a plan or top view of the same. Fig. 3 is a longitudinal vertical section on linea; a" of Fig. 2. tive detail view of the clearer-bar.

Fig. l is a perspec- F1g. o is head.

Fig. G is a detail view illustrating the attachment of the side guards to the under side of the axle.

Fig. 7 is a detail view of the head, showing the manner in which the rake-teeth are secured in place; and Fig. S is a front elevation of a portion of the rakehead, showing the manner in which the raketeeth are held in place.

Like letters of reference denote corresponding parts in all the figures.

Our invention relates to hand-dumping horse-rakes of that class in which the weight of the driver assists in rocking the rake-head for the purpose of raising the teeth and clearing the rake of hay, and our improvements consist in the detail construction and combination of parts of a rake of that class, as will be hereinafter more fully described, and particularly pointed out in the claims.

Reference being had to the accompanying two sheets of drawings, A designates the iiXed axle, having spindles A A secured to or projecting from castings A2, iitted to the ends of the axle, on which spindles are mounted the wheels ll B.

The rake-head may be of any approved construction that permits of its being rocked or tilted upon the axle, although in this instance we have shown it composed of the front rails C O', one above the other, and the rear rail C2. The lower front rail O', as will be observed, is secured at each end to the castings c by means of bolts c. The rear rail O2 is also secured to the castings by means of bolt c", while the castings c are pivotally mounted on the projecting ends of the rod c. The rod c is itself pivotally supported at its ends in flanges projecting upright from castings cs, secured on the top of the aXleA atits ends. The yielding or springactuated rake-teeth D are secured Within inverted-U-shaped hollow lugs D by means of cyebolts d, through the eyes of which the said teeth pass, and are securely clamped in place by means of nuts d upon the outer ends of the said eyebolts, which nuts bear against the plate D. The lugs are formed at their lower ends with an opening d2, through which extends the rod c for holding the said lugs in position, the said rod being secured to the castings c at each end of the rake-head.

The rails O C, blocks c3, and castings c are secured together by bolts c, one passing through each end of said rails, blocks, and castings, as clearly shown in Fig. 2, for holding the parts together.

The clearer-bar E is provided with the usual clearer-loops F, one for each rake-tooth, in the well-understood manner. The forward ends d3 of the rake-teeth rest in guides E', Fig. 8, the upper and lower ends or shanks c e of which move in openings formed in the rails O and C of the rake-head. Around the lower shank e is placed a coiled spring e2, which bears against the rail C and the loop or ring c3 of the guide. Thus if the rake-` teeth strike an obstacle in passing over the ground the springs on the guides will allow them to rise as well as hold them down to their work, thereby preventing injury to the same.

The drivers seat G is supported upon a rearwardly-inclined bar II, the lower end of which is hinged at I to the forward part of the frame, said frame consisting of the ordinary hounds X X, fixed to the axle and braced by the braces a, cross-pieces a: x', and the thills or tongue x2. To the upper end of the seat-bar H, below the seat, are pivoted two arms J J, the lower ends of which are forwardly bent approximately at right angles and pivoted to the cross-pieces K K, which aresecured to the front rail G and the rear rail C2, thus additionally connecting these rails of the rake-head. The latter is operated by the driver either by means of an elbow L, pivotally secured upon a casting l on the cross-piece and connected bymeans of a connecting-link M to the arm N,seeured to the rails C and C2, and through which, as will be observed, extends the rod c, carrying the lugs D', through which the rake-teeth pass, or by means of a treadle O,which is in like manner connected to the oscillating or vibrating rake-head by means of the rod P, which connects with the treadle O and with the rake-head, so that by pressing on the said treadle the rake-teeth will be elevated or depressed, as desired. As these means foroscillating the rake-head form no part of our present improvements, further explanation of the same is not deemed necessary, as they do not differ in their construction and operation from horse-rakes of similar construction.

By pivoting the rear ends of the pair of arms J to the cross-pieces K K, .slightlyforward of the axis of the rake-head, it will be seen that we get a bearing for the weight of the driver on the rake-head in front of its axis, and also at two different points in its length, thereby distributing the strain upon two different points approximately near the middle part of the oscillating rake-head. It follows that when the driver operates either the lever or the treadle, or bot-h of these devices, his weight will assist in depressing the forward part of the oscillating rake-h ead, thereby elevating its rear part andgreatly facilitating the dumping of the hay. During this process of elevating the rake-teeth the clearer-bar E is raised with them, said bar being pivotally attached to the standards Q Q by means of the arms R, which are rigidly secured to the bar E. I/Vhen the rake-head is rocked for the purpose of raising the teeth, they will slide back through their appropriate clearer-loops F, which operate to push the accumulated hay off from the teeth, so as to dump it on the ground. Experience with this class of rakes has proved, however, that when the teeth are raised to their fullest extent for the purpose of dumping they are apt to bind or stick between these loops and the clearer-bar to which the loops are attached, and which runs transversely across the teeth and is supported upon the saine, and to overcome this difficulty and cause the teeth to move freely through their respective loops without the liability of binding we provide the clearer-bar E, in proximity to the arms R, or at any other convenient point, with the bail-shaped irons S, which project forwardly at right angles to the series of loops F, so that when the teeth are elevated to a certain point they will strike against the under side of the irons, and

thereby lift the clearer-bar up above and clear of the teeth, so that the latter may move freely forward and back through their respective loops without coming in contact with the clearer-bar proper, thereby obviating the danger of binding of the teeth, which might otherwise seriously interfere with the operation of dumping. Moreover, these rearwardly-projecting bails or irons prevent wear of the clearer-bar by the teeth, so that theI bar will last much longer and be made much lighter than in rakes of this class which are not provided with our improvements.

In order to prevent the accumulated hay from being discharged sidewise toward and into the wheels, we provide our improved rake with peculiarly-constructed side guards, one on each side, each of said guards consisting of an arm T, pivoted near its inner end upon the bolt U, inserted through the downwardlyprojecting ear V,'which is suitably secured to the under side of the castings A2, on which v also are t-he spindles. The extreme inner end of each of the arms bearing against the under side of the castings prevents the opposite or rear end from dragging on the ground, but permits of their moving up to pass over rocks or other obstructions, dac. rlhe rear end of this arm T is provided with a series of upwardly and rearwardly projecting iin gers WV, forming a guard or barrier for the hay which accumulates underneath the rake-teeth. If during the progress of the rake these guardarms should strike a stump or other obstruction, they will be raised in their bearings while passing over the obstruction and again dropped back into their normal position by their own gravity. By the employment of these movable side guards we cause theload of hay at each discharge to be dumped in a solid lump, which may be easily gathered up afterward.

Having thus described our improvements, we claim and desire to secure by Letters Patent of the United Statesl. In a horse-rake, the combination of the axle, the castings o8 secured thereupon, the rod secured to the castings, the inverted-U- shaped hollow lugs on the rod, eyebolts in said lugs, the rake-teeth extending through the lugs and the eyebolts, and nuts on the eyebolts bearing against the outer sides of the lugs, substantially as and for the purpose specified.
