JAMES HOLLINGS WQRTH, OF CHICAGO, ILLINOIS, ASSl GNOR TO J. M.

WA'NZER, OF THE SAME PLACE.

Letters Patent No. 65,573, dated June 11, 1867.

TMPBOVEMBNT IN HORSE-RAKES TO ALL wuo 'rr MAY comm Be itknown that I, JAnns HoLLmoswonrn, of Chicago, in the county of Cook, and State of Illinois, have invented certain new and useful improvements in Horse Hay-Rakes; and I do hereby declare that the following is! full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making a part of this specification, in which-- Figure 1 is a longitudinal section, taken in a vertical plane through the centre of an improved rake. Figure 2 is a perspective view of one of the tubular hearings. Figure 3 is a perspective view of one of the perforated guides. .Similar letters of reference indicate corresponding parts in the several figures. This invention relaths to improvements on horse hay-rakes, in which the rake-teeth are applied to an oscillating frame in such manner as to be supported at two points by said frame, and at an intermediate point by the axle of the transporting-wheels, or by bearings above this axle.

The nature of my invention consists in an oscillating tubularbearing, which is constructed with three passages through it, constituting a means for attaching a tooth to a bar, so as to articulate thereon, and also a means whereby the tooth can be readily attached or detached at pleasure, and adjusted forward or backward,

according to the character of the ground over which the rake is to be drawn, as 'will be hereafter described.

' The'invorit ion'itls'o consists in sustaining the front ends of the rake-te ethby means of sliding-pins, having eyes formed on them for receiving the ends of the teeth, said pins being sustained upon springs, and supported in guides abovcand 'below their eyes, in such manner as to form supports for the teeth against lateral displacement;

also to afford the teeth on additional spring action to hold'them down to theirwork, and allow them to rise and pass over obstructions which may be in their path, all as will be hereinafter described.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

The carriage upon which the rake teeth are supported consists of an axle, A, two transporting-wheels B, nnd thills' C, which latter are secured to. the axle A, and; provided with a platform, D, upon which the driver can stand or sit. At' eachend of the axle A is an upright standard, and at intermediate points between these standards are othenstandards, for sustaining a rod, a, in'a position parallel to and above the axle. Upon this rod a and near its extremities are pivoted the longitudinal arms or levers E, which project out in rear and forward of the rod a, and have transverse bars F F? secured to their ends, which bars are parallel to the said rod.

This constitutes an oscillating frame for sustaining therake-teeth at two points. Another arm or lever, G, is pivoted to rod a, and secured at its ends to the bars F F, for the purpose of stiffening the frame and strengthening the bars at that point where the power is applied for oscillating the frame. For this latter purposes. lever, H, is used, which is pivoted to the platform D, and connected to the front end of arm G by means of a link, 0, as shown infig. 1. The front liar F has another bar, dva rranged 'ahove it and parallel to it, and secured iu place by. means of studs and bolts. This bar 02, as well as the lower bar F, should be perforated for receiving aipuunibcr of eye-pins, g, as will be hereinafter described-.1 The rear b'ar F is provided on its upper edge with a number of staple-guides, It, for allowing the rake-teeth to spring-upward and staying them laterally. Upon the rod'u a. number of eye-bearings are applied for supporting each-tooth at an intermedia'tepoint between the bars FF, and in a plane which is beneath the plane of these bars. Each one of the bearings J consists of a tnb e,j, through which'the rod a passes a central projection, is, through which the tooth passes, and a screw-tapped hole for receiving the set-screw has shown in fig. 3. The hole through which the tooth T passes 'is at right angles to the tube through which the rod i passes, and the hole for receiving the set-screw is perpendicular to the tooth, so that this screw serves to secure the tooth rigidly to the bearing, and, to admit of the forward or backward adjustment of the tooth. The tubes j are made of suflicient length to properly space the rake-teeth; and the ends'of those tubes abut against each other, and are thus prevented from endwise play. The end play of these tubes, collectively taken, is prevent-ed by the studs or standards which'support the rod a, about which the bearings all oscillate. The rake-teeth are constructed of the double curved form, substantially as represented in fig. 1, a.nd are passed through the staplc-guides h on bar F, through the projections k'on tubes J, and finally through the eyes i on the pins g, as shown in the drawings. The teeth thus applied to the oscillating frame can be collectively oscillated, ruised, or lowered, by vibrating the hand-lever H, and while this is the case, each tooth is allowedto articulate independently of other teeth about; the rod a. The forward portions of the teeth, or these ends which extend beyond the bearings J, serve as springs for keeping the reero'r raking portions of the teeth down to their work with o yielding elastic pressure; thus theroke-teeth are allowed to spring upward over obstructions. The eye-pins g are construstcd with circular flanged supports it, above and below their eyes i, for properly holding the ends of the teeth, and these eye-pins g are supported upon springs s, which may be partially received within depressions in the guide-bar F, as shown in fig. 1. By thus inserting the front ends of the rake-teeth through eyes which are formed on vertically sliding pins that are guided above and below said eyes, the forward ends of the teeth will be prevented from working out of place, and will always be acted upon by the springs s when the raking port-ions of the teeth meet with resistance from obstructions. It will be seen by reference to fig. 1 that the rake-tooth T has u gradual curve from the supporting-bur F to the supporting her F, which feature, in conjunction with the set-screw l on bearing J, allows the tooth to be adjusted backward or forward, as indicated by the red lines in this fig. 1. By this arrangement one set of teeth properly constructed can he adopted for level lend, or for rough and uneven iand, and for heavy and light raking.

Having thus-described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The construction of a ral e-toothbenring 3', with three passages. at right angles to each other, when said bearings are of a form to abut directly against one another, and the teeth extend clear through the top passage of the bearing, substantially in the manner and for the purposes described.

2. The construction of the eye-bearings g, for supporting the rake-teeth T, an holding the spring, substontinlly iLS described. 7

,3. The'combinotion of the jointed bearings J and eye-bearings g with a rake-tooth of the form substantially as herein described.

4. The combination of the bearings J with set+screws Z, the rocking-frame with its arms, and the eye-bearings g with their springs, substantially in the manner and forthe purposes described.
