GRAIN CRADLE.

Pauzented Nov. 9, 1886.

UNITED STATES PATENT OFFICE.

WVILLIAM BENJAMIN SMITH, OF ATLANTA, GEORGIA.

GRAIN-CRADLE. I

SPECIFICATION forming part of Letters Patent No. 352,372, dated November 9, 1886. I

Application filed October 23, 1885. Serial No. 180,706. (No model.)

grain-cradles.

The object is to provide ametal cradle of such construction and proportions that it will be lighter and more durable than those hitherto constructed.

A further object is to provide a cradle which will not hang in the grain or in vines, even when the grain is fallen down.

A further object is to provide a cradle which may be manufactured at less cost, be more easily repaired, and adjusted to the blade and handle than those hitherto constructed.

With these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of my improved cradlein perspective. Fig. 2 is a detached view of one of the crossrods and tubes for securing the fingers in position. Fig. 3 is a view of one of the fingers, and Fig. 4 is a detached enlarged view of the bar for securing the ends of the fingers to the handle. Figs. 5 and 6 represent cross-sections through lines a x and 3 g, respectively, of plate 9.

Letters Patent No. 322,885, entitled graincradles,were granted to me on July 21, 1885, andthe present invention relates particularly to improvements upon the construction there shown and described.

a a represent tubes made of sheet iron, tin, or any light metal, having transverse slots j j cut in them to admit the metallic fingers f. One of the tubes a is located at ornear the point of the blade, and the other a short distance from the heel of the blade, and both extend transversely, or nearly so, to the blade. Rods I) extend through the tubes to, and are bent at right angles at their ends next the blade, and providedwith eyes K, through which they are bolted to the blade by bolts m, provided with draw-nuts. The ends of the rods 1) which project through the opposite ends of the tubes a extend through the upper rail or border finger, 01,, of the cradle, and the said rail or finger is secured on the rods 12 in contact with the ends of the tubes at by means of nuts working on the threaded ends of the rods.

g is a bar made of light sheet metal having one edge turned to giveit the required strength, and provided with a series of holes for theends of the fingers to hook into. The bar 9 is secured to thelower end of the handle or snath by abolt, g, and at its opposite end'to a bracket or stay, h. The latter consists of a piece of sheet metal folded over at right angles and secured to the handle by screws Z Z,'one located near its end and one extending through the fold. The bracket or stay h is provided with a series of perforations, I, through which the end of the bar 9 may be secured at different distances from the handle, for the purpose which will hereinafter appear.

The fingers f consist of metallic rods or tubes having their points f bent in the form of an eye or hook, and adapted to embrace the rod 1) within the tube a at the point of the blade; thence they extend to the rod 7) within the other tube a, where they are bent to form an eye or loop, f which is adapted to embracethe rod 1), the finger entering and coming out of the slot j, and thence the finger extends to the bar g, in one of the perforations of which it is hooked. The upper rail or border finger, 12, projects past the end of the heel-tube a, and from its extreme end a brace, 0, leads to the bracket h, to which it is secured, preferably by means of the same bolt, h, which secures the bar g to the bracket. to the end of rail or border finger n by means of a pair of adjusting-nutsfli, which work on its threaded end, and serve to regulate the angle of therail n with respect to the handle or snath, and hence the set of the point of the cradle. A stay-rod, d, extends from the rail or finger a at the end of the rod 2) to the lower end of the handle or snath, and is secured to the latter,preferably by means of the same bolt which secures the lower end of the bar 9 to the handle. It is secured to therod b by the'nut b, which secures the rail nthereto. A third brace, e, extends from the heel end of the rail or finger n to the rod 1) near its blade end, and is provided with an eye or loop at each end,

The brace c is secured which embrace, respectively, the rod and the rod 1) within the tube, entering the tube a through one of the slots j. A fourth stay, 0, extends from the rail or finger n at the end of the rod 12 to the upper end of the bar 9, and is secured conveniently by the bolts b and h.

By moving the upper end of the bar gaway from and toward the handle or snath by means of the perforations Z and bolt h the upper part of the cradle is made to assume the desired position relatively to the blade. 1 The bolts m m, which secure the rods b to the blade, serve to secure the blade firmly to the cradle, rendering it stiff and capable of passing through extremely heavy grain Without ,warpiug or giving way.

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

1. In a graiucradle, the combination, with the blade and handle or snath, of a bar secured to the handle or snath in swinging adjustment, and a series of fingers secured to the blade and the swinging bar, and adapted to be adjusted by the adjustment of the bar,'substantially as set forth.

2. In a grain-cradle, the combination, with the handle or snath and the blade, of the movable bar 9, fingers f, bracketor stay 72, and means for fastening, substantially as set forth.

3. In a grain-cradle, the combination,with the tubes (1, having transverse slots formed therein, of the fingers f, adapted to enter the slots, and the rods b, for securing the fingers in the tube, substantially as set forth.

4. In a grain-cradle, the combination, with the handle or snath, a bar adj ustably secured thereto, and rods extending longitudinally through slotted tubes located transversely to the blade, of fingers attached to the adjustable bar and held in position by the rods within the tubes, substantially as set forth.

5. In a grain-cradle, the combination, with the upper rail or border fingerfthe handle, and the blade, of the slotted tubes at a, fingers f, and rods b, substantially as set forth.

6. In a grain-cradle, a tube provided with transverse slots adapted to receive loops or eyes formed on the fingers, in combination with a finger-securing rod extending through the tube, substantially as set forth.

7. In a grain-cradle, an adjusting-bar, g, having its edge turned over to increase its strength, and provided with a series of perforations for the attachment of the ends of the fingers, substantially as set forth.

'8. In a grain-cradle, the combination, with the handle or snath, the adjusting-bar y, secured thereto, and the cradle-fingers secured to the adjustable bar, of the bracket h, secured to the handle or snath and folded over onto itself to carry one end away from the handle, the' free end being provided with a series of holes for the attachment of one end of the adjusting-bar g, substantially as set forth.

9. In a'grain-cradle, the combination, with the fingers adjustably secured to the handle, 7

the handle, and the stay-rods, of the slotted tubes adapted to separate the fingers, the rods 1), extending longitudinally through the tubes, and the blade bolted to the rods b, snbstam tially as set forth.

10. In a grain-cradle, the combination, with a series of fingers secured to the blade and to an adjustable bar attached to the handle or snath, of the stay-rods, substantially as described, adapted to secure the fingers to the handle or snath, substantially as set forth.
