UNITED STATES rATEN'r OFFICE.
GEORGE W. SLOUGH, OF CANTON, OHIO, ASSIGNOR TO E. BALL, OF SAME PLACE.
MAKING GUARD-FINGERS FOR HARVESTERS.
Specification of Letters Patent N o. 28,206, dated May 8, 1860.
To all whom 'it may concern:
Be it known that I, GEORGE WV. SLOUGI-r, of Canton, in the county of Stark, in the State of Ohio, have invented certain new and useful Improvements in the Mode of Manufacturing Fingers or Guards for Harvesters; and I do hereby declare that the following is a full, clear, and exact descript-ion of the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, forming a part of this specification, in which- Figure l represents a top or plan View of the forming, leveling, and truing block which I have invented to facilitate and render more perfect the manufacture of wrought iron guards or lingers for harvesters. Fig. 2 represents a side view of the same block, and Fig. 3 represents an end view of the block.
The top surface A, of the metallic block B, is level or of the same height, while the part A is higher, and rises at right angles to A. The top of the block is provided with three grooves l, 2, 3, the forms of which are fully shown in the drawings, where the ends fl', (Z2 and d3 of the grooves are represented as being deeper than the ends e, e2, and e3. The grooves 2, and 3, are provided near their centers with depressions or conc-aves l), c, see Fig. l.
The operation is as follows: The iron being rolled at the mill into the proper shape, it is cut into sections, Fig. 4 representing a top view of so much of a bar as is required to make one guard, Fig. (i is a side view of the same, and Fig. S a cross section. One end of a blank after being properly heated, is placed in the groove 1, so that it will project by the raised part A, a certain distance when the workman swages down into the groove that part which projects by the part A', until it is even with the top of A. By this operation the shoulder f, and shank g, are formedsee Figs. 5, 7 and 9. The outer end of the section or partly formed guard is then heated and placed in groove 2, so that the shank g, will project bythe side of the block B, leaving the shoulder f flush with the side of the block at (Z2. The workman then swages the metal into groove 2, and concave b, until the top of the metal is even with the surface A of the block B. By this operation the part z', is finished, and the bulge 71 located and formed-see Figs. 10, l2, and 14. The bulge end h, of the guard face A, of the block B.
By this operation the part j, which forms the top or lip of the guard, is worked into the proper form, while the part le, on which the cutter works is leveled and truedsee Figs. l1, 13 and l5. All that remains now tobe done is simply to heat the guard and bend the lip part y', up over so that it will be even with the shoulder f. The bend is made near the center of bulge In After the guard has been bent the bulge L, is swaged out to form the point of the guard..
Fig. 1G represents the form of an ordinary guard in which similar parts are indicated by the same letters of reference. By my mode of manufacturing wrought iron guards the shanks g, shoulders f, and surfaces 7c are all rendered very uniform; while the guards can be manufactured with great rapidity, thus producing two very important results, viz, first a. uniform guard, and second, a cheap guard. The block may be bolted to any suitable stand by ears a..
It will be noticed that by the formation of the bulge or enlargement 7:., that a sutiicient amount of metal is retained in the proper position to form the point of the guard after the end or lip j has been bent up over, an advantage which will be apparent to those skilled in the a'rt of manufacturing guards.
I do not wish to be understood as claiming, forming guards by swaging, broadly considered, but what I claim as my invention and desire to secure by Letters Patent is- Forming the blank guard as shown in Figs. 11, 13, and l5, from a section of a bar or piece of wrought iron as shownin Figs.
4, 6, and S, by the mode or process substantially as herein described, whereby the shank g, shoulder f, surface 7c, and lip j, of each guard are formed with precision and celerity, while a sufficient amount of metal is reserved at the point 11 to form the point of the guard.
GEO. W. SLOUGH.
