Description
AJOHN K. oNiniL, or KINGSTON, NEW YORK.
=Letters Patent No. 99,939, dated February 15,1870.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, JOHN K.ONEIL, of Kingston, in the county of Ulster, and State of New York, have invented an improved Horse Hay-Rake; and I do hereby declare that the following-is a full and exact description thereof, reference lbeing had to the accompanying drawings making part of this speciiication,
Figure 1 being a top view of a horse hay-rake con strueted with my improvements.
Figure 2, a longitudinal vertical section thereof, in airplane indicated by the line :e x, iig. 1.
Like letters designate corresponding parts in both figures.
The rake is mounted on wheels A A, upon the axle B of which are secured blocks a, a, whereto the bars or heads C G of the rake-teeth D D are severally pivoted around a pivot rod or rods, 11. j
In order to allow the rake-teeth D D to yield separately on striking an obstruction, I joint the bars() O at points d d, preferably at a ,shorter distance from the upper ends c e of the rake-teeth than the length of the said teeth extend, and I cover the jointsby springs E E, which are secured upon the upper sides of the bars, most properly extending the greater part ofthe length of the said bars, and having their forward ends rigidly attached to the main parts of the bars by screws ff, or their equivalent, while the rear ends thereof, overlapping the short jointed pieces c c of the bars, are provided .with longitudinal slots, g g, that play on screws or bolts hh, driven into the said jointed pieces.
The joints of the bars at d d are of such form, as shown at el, or otherwise, that the bars cannot bend downward beyond their proper form', as shown in g.
2, but that they can bend freely upward, having only the force of the springs E E- to resist them. This' force of the springs should be sufcient to hold the raketeeth rmly, and Without yielding, to their work, as
long as only the hay resists their advancement, and
yield only to a real obstruction. By thus rendering the springs inactive except when an obstruction overcomes their force, an important advantage is gained over springs which continually act on the teeth, and yield in proportion to the resistance of the hay as well as to obstructions, and, for the same reason, over raketeeth or bars which are elastic in themselyes.
The form which the springs assume in yielding is indicated clearly in iig. 2 by dotted lines.l
The slots g g allow the required iiexure of the bars, and at the same time, iu connection with the screws or bolts h h and the rigid attachment of the forward ends of the springs to the main bars, hold the raketeeth firmly against lateral yielding.
The location ofthe joints l d so near to therake-teeth causes a rapid change of the angle of the teeth in yielding, so that though when running they in'cline forward nearly in a horizontal direction, they rapidly change to a vertical position, or evento an inclination back-ward from a vertical line, and thus quickly and easily free themselves from obstructions. rlhis is a valuable feature of the invention. I am thus enabled to give elasticity 'and facility of yielding to obstructions, to raketeeth running on the ground nearly in horizontal posiiig. 2, particularly at the rear ends.' The purpose is thus I easily and well accomplished.
The rake-teeth are held down to their work together by means of a cross-bar, G, which is pivoted by arms 7i: k around the pivot ,rod 11 of the teeth-bars.- From this cross-bar curved bolts'll extend downward into and through the teeth-bars, as represented; and in order that the bars may have room and capability ofrisingseparately to acertain extentfwhen yielding to an obstruction, as shown by dotte'dlines in iig. 2, there is a certain distance between the cross-bar and the teethbars for the reception of coiled springs, mm,which will yield and allow the teeth-bars lto playupward on their bolts l l, while the other bars remain pressed down to their work. This cross-bar also serves, by means of the curved bolts l l, with heads below the teeth-bars,A
to lift all therake-teeth simultaneouslyfrom the ground when required. The mechanism for raising and lowering the cross-bar is connected therewith by means of arms n n, projecting upward from the'pivoted arms 7c k, and connecting bars or rods p p, extending forward to vibratory arms 1' lr, which project upward from the shaft s of a treadle, I, situated at a proper position in front of the drivers seat, H. This treadle extends both above and below its shaft, so thatthe feet of the driver may act either to Iraise the rake-teeth by pressing against the upper end of the treadle, or to hold the rake-teeth down totheirwork byvpressing against the lower end of the treadle. Pinstt project from the sides of the treadle, as shown, 'on which to rest the feet in controlling the rake.
In addition to the foot-treadle for raising and-lowering the rake-teeth, a hand-lever, L, is employed for thesame purpose, it being pivoted at u to the side of he driver-s seat, and connected by a rod, fu, with one of the bars or rods p p, as shown. This lever is generally used in connection with the trcadle I, the action upon it by drawing back with the arm,while that upon the treadle is by pressing forward with the feet, to raise the rake-teeth from the ground, being very advantagenus to the operator .in applying his strength, since one action braces the'otber.
A springoatcb, M, being attached to a crossbar,w, between the thills N N of the rake, and catching over the treadle `Iwhen the rake-teeth are completely raised, serves to hold the same up when required. It is readily detached by the foot. Any equivalent device for the purpose may be employed.
Any other 'form or arrangement of springs which will full the same purpose may be used instead of the at springs E E. So, also, the. joints d d may be constructed or produced in any equivalent manner.
What-I claim as my'invention, and desire to secure by Letters Patent, is
i The jointed teeth-bars C O, substantially as and fot the purpose herein specified. l
Also, the downwardly curved njointed teeth-bars C Witnesses:
