Description

. H. H. SCQVILLE. Making Mold Boards for Plows.
Patented May 29, 1860.
UNITED STATES PATENT OFFICE.
HIRAM H. SOOVILLE, OF SYRACUSE, NEW YORK.
MACHINE FOR MAKING MOLDBOARDS FOR PLOWS.
Specification of Letters Patent No. 28,507, dated May 29, 1860.
To all whom it may concern:
Be it known that I, I-IIRAM H. SoovILLE, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Devices for F orming Moldboards for Flows; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification.
To make and use my invention, construct the frame work (A) of strong timbers, or of iron. Make the cylinder (B) of iron having one end of larger diameter than the other thus giving it a conical form. Out the cylinder in two parts from end to end, and attach the gudgeons (O) to the center of each end of one of the parts. Place the cylinder in the frame work so that the gudgeons (C) may revolve in boxes attached to the frame at To the lower or flat face of the cylinder (B) attach the metallic frame (E) by the screws (F). On each side of the cylinder or forming block (B) make a lip (G) projecting above the lower margin of the cylinder, and giving suflicient space between the lip and block on either side to admit the edge of the wrought iron or steel plate (H). By moving the side piece of the frame toward the large end of the cylinder, the plate is securely fastened to the forming block. The pressure roller (I) is attached at each end to sliding blocks (J), which blocks work in grooves in the frame (A), and are attached to and operated by elbow joint levers (K).
To use my invention take a plate of iron or steel of any desired thickness and cut in the shape necessary for the mold board. Place the lower edge (L) between the lip (G) of the frame (E) and the lower edge of the forming block (B). Close the lip onto the plate holding its lower edge firmly.
If the plate is not of too great thickness it may be bent cold, but in most cases it should be heated and bent while hot. After fastening the plate to the cylinder pass the pressure roller (1) against the plate by depressing the elbow joint levers (K), and then passing the whole frame with the roller (1) over the cylinder, in the form of the pressure roller corresponding with the form of the cylinder, it gives to the plate the form of its external surface. The conical face of the cylinder may be made straight from end to end, or it may be made hollowing as shown in the drawings (Fig. 1.) The purpose of making the forming block of a conical form is to give to the mold boards of plows an increasing curve from the front to the rear part. The forward part of the plate being formed on the largest part of the cylinder it follows that the rear part of the plate has a smaller curve, the effect of which is to cause the mold board to operate upon the furrow in plowing with an increasing inclination; whereas if the plate was formed on a straight cylinder the curvature would be the same from the front to the rear part of the mold board. A greater or less curvature may be given as may be desired by the part of the cylinder upon which the plate is formed.
hat I claim as my invention and desire.
to secure by Letters Patent, is-
The use of a conical forming block for shaping mold-boards of plows when the same is so arranged with the pressure roller (constructed substantially as described) and frame work as to operate in the manner set forth.
