Application tiled March 20,1893.

fo @ZL whom, t 77u03/ concern:

Be it known that I, CASPER F. SEARCH, of

Appleton, in the county of Outagamie and State of hfiscoxisiii, have invented certain new 5 and useful Improvements in Seeders, of which the following is a specification.

This invention relates to certain improvements in seeding machines, and more particularly to a novel construction of the frame to of suoli machine.

In the construction of seeders the hoes, feed box and feed tubes are all mounted upon a frame which is pivoted upon the main axle to which one of the ground wheels is secured,

t5 and the other ground wheel turns loosely on the axle. The tongue also is rigidly connected to this frame and pivotally connected t the axle, and the perfect working of the seeder depends, to a large extent, upon the frame zo maintaining its shape and rigidity so that the several devices, and particularly the geared parts and hoes, are preserved in proper alignment and relation to the frame and to each other.

z To this end my invention consists in combining with the frame, which is composed of metal bars set edgewise in a vertical plane, of a system of rigid braces which impart the desired rigidity to the frame, and which braces 3o are also of such form as to furnish bearings for the draft bar on which the hoes are mounted. f

In the accompanying` drawings, Figure 1 is a perspective view of the machine, the tongue 3 5 broken away; and Fig. 2 is a plan view.

In the drawings, A represents the feed box which is bolted to castings secured to the ends of the U-shaped frame bar B, the lower ends of said castings being provided with bearings 4o for theaxle C.

D represents a metal bar which is disposed edgewise and has its respective ends connected to the castings, which form the bearings above mentioned.

The bars B and D are arranged parallel to the axle and to each other.

E represents braces substantially of V- shape and constructed in one piece, the apex of the braces being secured to the front mem- 5o bers of the U -frame, while the ends of the legs of said braces extend diagonally back to and Serial No. 466,847. (No model.)

are secured respectively to the bar D at the tongue and at the end of the frame.

F represents ordinary braces connected by the same bolt which connects the V-braces above mentioned to the front member of the U -frame and having their forward ends connected by the bolt G to the tongue.

H represents V-shaped hanger braces having their upper ends secured to the end mem- 6o bers of the U-frame B and apertured at their bends to receive the draft rod I, to which the tongues of the hoes-.I are pivoted. These hanger braces are also constructed in one piece.

K represents intermediate hanger braces Whose middles are vertically disposed and perforated for the passage of the rod I, while their ends are twisted at right angles to the middle and are secured respectively to the 7o frame bars B and D. Heretofore each hanger has usually been constructed in two pieces having their lower ends lapped by eachother and provided with apertures for the passage of the rod. By making each hanger from a single piece it serves not only the usual purpose, but also as a rigid truss or brace for the frame. The connection of the forward ends of these hanger braces K is made bythe same bolt which securesthe V-shaped braces E to 8o the frame bar B. The end members of such frame bar project rearwardly beyond the feed box and have the bearers K to which the lifting roll is pivoted.

M represeutthe feed tubes which are hinged at their upper ends to the spouts on the feed box in the usual way.

The weight of the seed box, hoes and other accessories of a seeder is necessarily great in the aggregate, and if the implement is fur- 9o ther weighted by the construction of a heavy frame the draft is increased beyond the capacity of a team of horses. Upon heavy seeders, therefore, it is customary to employ three and even four animals. 95

It is the chief object of my invention to reduce the weight of the machine while at the same time constructing it in such manner that the frame shall be rigid and the various parts preserved in proper alignment and reroo lation to each other under all of the exigencies of service. I have accomplished these beneficial results in a very marked degree by the construction above described.v The Weight of'my'metal frame is very much less than that of a wooden frame or of a metal frame of ordinary construction having equal strength. These desirable objects have been accomplished, mainly, by the employmentof the V-shaped braces E between the parallel bars of the main frame. Heretofore that portion of the brace E extending from the middle of one side of the front bar of the frame back to the rear bar near the tongue has not been employed and, as above pointed out, thehangers have been made in two parts and their chief purpose was to serve as hangers. In my construction they not only serve as hangers but become braces which are efficient to impart the desired rigidity to the main frame. In previous constructions and .WhereY these hanger braces were constructed 1n two parts, the strain o'n the draft rod has been 'transmitted to the rear bar of the main frame, tending to bend said bar between its points of attachment to the frame. VIn my construction the strain is transmitted to the tongue and to the rear bar near the points of its :connection with the tongue and end castings, and the most severe tests have shown that the implement is adapted to work in all conditions of soil without any liability of springing or bending any of the frame inember's, and therefore proper alignment of the parts is` secured.

I claim-- 4 l. In a seeder, the combination with a metal frame having frame members arranged parallel to each other and to the axle, of continuous V shaped braces whose legs extend diagonally between and are connected-to said frame members respectively, substantially as described.

2. In a seeder, the combination With'a metal frame having frame members arranged parallel to each other and to the axle, of continuous V shaped braces whose legs extend diagonally between and are connected to said frame members respectively, the apex of the brace being connected to the front member of the frame between its end and the tongue and the opposite ends of the legs being connected to the rear member of the frame, substantially as described.

3. In a seeder having a metal frame, the combination with the frame members, of contin nous V shaped braces, for said frame inembers and continuous V shaped hanger braces connected to the frame members and perforated at their apex to provide bearings fora draft rod, substantially as described.

4. In a seeder having a metal frame comprising metal bars arranged parallel to each other and to the axle, continuous V shaped braces having the legs thereof connected to the rear of said frame members and the apex to the front frame member, of continuous V- shaped hanger braces having the end of their legs secured to the front frame member coin-A cident with the apex of theframe brace and the apex of the hanger being perforated to provide a bearing for the draft rod, substantially as described.
