UNITED STATES PATENT OFFICE.
MICHAEL LCUGHRAN, OF PITTSBUEG, PENNSYLVANIA, ASSIGNOR TO HIM- SELF AND JAMES B. LOUGHRAN, OF SAME PLACE.
IMPROVED METHOD 0F FORMING BLANK CLIPS FOR SINGLE-TREES.
Specification forming part of Letters Patent No. 48,699, dated July 1l, 1865.
l To all whom it mag/.concern Be it known that I, MICHAEL LOUGHRAN, of Pittsburgh,in the county of Allegheny and State of Pennsylvania, have invented a new and Improved Method of Forming Blank Clips for Single and Double Trees; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specitication, and to the letters ot' reference marked thereon.
The nature of my invention consists in rolling iron so as to form thin flat bars with a raised bead 7 running longitudinally on both sides, either in the center of the bar or near one edge, and depressing the bead so raised in certain places on one or both sides, thus forming flattened spaces at regular intervals, in such a manner along the bar that by cutting away that portion ofthe tlat on each side of the raised bead the bar can be turned and welded, forming a substantial clip or clevis in a cheap, neat, and expeditious manner.
To enable others to understand my invention, I will proceed to describe its construction by reference to the accompanying drawings, in which- Figure l represents an end view of a small iron bar, A. This bar while hot is passed successively' through the grooves of a lproperlyconstructed pair of rolls until it assumes the various shapes indicated by the end views, Figs. 2, 3, 4, and 5, which, while it rolls the body A of the bar out thin, leaves a raised bead, C, down the center or near one edge, as shown at Fig. S. This bar, so rolled, is then passed through another groove in the same rolls, having blank spaces at regular points around its periphery, and as the bar passes through these blank points, depress the bead C in certain places, forming a series ot' short beads, having a flat space, B, between each, as represented by Fig. 6. Fig. 7 is a view of the opposite side of the bar, the bead C being left continuous. The iron being rolled, as shown, that part of the flat on each side ot the short bead C is out away, as indicated by the dotted lines at Fig. 6. The blank clips are then taken from the bar'by severing or cutting through the center ot' each bead, which leaves the blanks so shaped that they can be easily bent and welded to form a finished clip or clevis, (represented by Fig. 9,) having a bead, C, extending around the outside, which not only adds toits appearance, but serves to strengthen it at those parts where strength is most needed.
Having thus briey described my invention, what I claim is- As a new article'ot' manufacture, bars of iron, having a raised bead running longitudinally on one or both sides, whether said beads are in the center of the bar or near one edge, and with dat-tened spaces on one or both sides at regular intervals along the body of the bar, made by depressing the beads incertain places without regard to the shape of the beads,l so so as to form clips and clevises, in the manner herein shown.
` MICHAEL LOUGI-IRAN.
