IMPROVEMENT IN HORSE HAY-RAKES.

Specification forming part of Letters Patent No. 158,073., dated December 22, 1874; application filed September 19, 1874.

To all whom it may concern:

Be it known that I, JAMES A. HARVEY, of Argyle, in the county of Winnebago and State of Illinois, have invented a new and useful Improvement in Horse Hay-Rakes; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure l is a perspective view of a horserake embracing my improvements, and Fig. 2 is a perspective view of a portion of the rake-head with one of the teeth applied.

Similar letters of reference indicate the same parts in both figures.

The invention consists in a novel arrangement of the rocking rake-head, vibrating clearer-frame, and levers for operating the same, for simultaneously rocking the rake-head and depressing the clearers, as hereinafter described.

It further consists in the C0lllbll12ll3l0l], with the ends of the rake-head, of hinged guards or fenders, for preventing the scattering of the hay at the ends of the rake, these guards or shields being combined with the rake in such manner as to maintain substantially the same relation to the ground, whether the raketeeth are raised or in operation, as hereinafter explained.

It further consists in a novel manner of combiningthe teeth with the rake-h ead, where by the elastic coil and the retaining or guide loop, which limits the independent movement of the teeth, are both formed in the same piece with the spring-wire tooth, as hereinafter explained.

In the drawings, A A represent the carrying-wheels, mounted upon a common axle, B, which also forms the rear transverse bar of the main or shaft frame, said frame, aside from the axle-bar B, being composed of the shafts O O, rigidly connected at their rear ends to said axle-bar, and of the transverse bars 0 G, united to the shafts (l in front of the axle. D represents a seat plank or bar, extending longitudinally between the shafts, and connected to the bars 0, and upon this bar D the seat D is supported in any usual or preferred manner. E E represent two longitudinal bars,

united at their forward ends by a loop-strap, e,

and, diverging thence and crossing the axlebar B, to which they are pivoted by loops or eyes at a, have a transverse bar, F, rigidly secured to them near their rear ends, said bar F for'mingthe head to which the clearer-rods f are attached. The bars E, passing over and slightly beyond the clearer-bar F, are provided with forked straps or ears b, in which upright lugs or ears on the rake-head G are pivoted in such manner as to permit the rake-head to rock or roll on its longitudinal axis. For giving this rocking or rolling movement, the rake-head, midway of its length, is provided with an upright arm or lever, g, to the upper end of which is pivoted the rear end of a linkrod, H,wl1ieh, nearits forward end, is connected with a lever, H, pivoted to the seat-plank D, within convenient reach of the driver. The forward end of this link H has a stirrup, h, formed upon or attached to it in such manner that the driver may operate it with his foot, for rocking the rake-teeth upward, or he may, with his foot, assist the operation of rocking the rake-head through the lever B. To the same pivot which connects the lever H and link H, or to any convenient point, either on the lever H or link H, is connected a link, i, the lower end of which is pivoted to the forward end of the bars E, so arranged that as thelink H, or lower end of the lever H is moved forward for raising the rake-teeth, the upper end of said link iis moved forward with them, and is thus made to draw upward the forward end of said bars or clearer-frame E, and thereby, as the rake-teeth are raised, to simultaneously depress the clearer rods, for assisting in the operation for relieving the rake-teeth of their load. The ends of the A rake-head have vertical plates or shields J pivoted to them through the medium of hin ged arms J, so connected by horizontal pivots that the arms J rand the plates J are free to maintain, by their own gravity, a vertical position, substantially as shown by the drawing, under any adjustment of the rake-head, and the plates, extending in longitudinal planes at the sides of the accumulating load of the rake-teeth, and in close proximity with the ground, serve to hold the grass within the action of the teeth, and prevent scattering or dragging of the same.

The construction of the teeth K and the manner of uniting them to the head are shown in Fig.2. The lower or tooth portion, it will be seen, is curved or bent in the usual form, and at its upper end it passes underneath the head G, thence in an open elastic coil, k, in front of and over the rake-head, from which point it passes down a groove in the rear face of the rake-head under the tooth portion K, where it is again turned upward, forming a U-shaped loop, M, in rear of and below the rake-head, embracing and limiting the play of the tooth, after which the upwardly-turned portion of the loop may, if preferred, be bent forward at a right angle, or thereabout, forming a shank, k which enters the rake-head; and a' clamping plate or washer, l, with a bolt or screw, 1, which passes between the arms of the U-shaped loop 70, serves to unite the tooth firmly to the bar or rake-head, thus forming a tooth simple and durable in construction, and one that may be quickly and easily removed and replaced when injured or broken.

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

1. The combination of the clearer-frame E E F, rake-head G, links H and i, and lever H, substantially as and for the purpose specified.

2. The guards J, hinged to and operating in combination with the rocking rake-head, substantially as described, whereby the scattering of the hay at the ends of the rake is avoided, while at the same time said guards are adapted to follow the surface of the ground under the different adjustments of the rake, as set forth.

3. The rake-tooth K, with its elastic coil k, guiding and retaining loop is and shank 20 formed in one piece and united to the rake head, substantially as described.

This specification signed and witnessed this 13th day of August, 187 4.
