THOMAS MIDGLEY, OF BEAVER FALLS, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO JAMES E. EMERSON, OF SAME PLACE.
WIRE BELTING.
`SPECII'JEECATION forming part of Letters Patent No. 398,429, dated February 26, 1889.
Application filed October 20, 1888. Serial No. 288,628. (No model.)
.To all wiz/0722, 'it may concern/.-
Be it known that I, THOMAS MIDGLEY, a
citizen of the United States, residing at l-eaver Falls, in the county of Beaver and Slate 5 of Pennsylvania, have invented certiin new and useful Improvements in Tire Belting; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the same.
M y invention relates to Wire belting, and has for its obj cet an in'lproved construction of said class of belts.
The ii'lvention will be hereinafter described, and particularly pointed out in the claims.
In the accon'xpanying drawings, which form part of this specification, Figure l represents a plan ot' a section of a sheet of intertwined sections of coiled wire; Fig. 2, a side elevation of a tube formed from said sheet; Fig. 3, a similar view of the tube after the helices have been elongated, and Figa a top and end view of abelt partly covered with rubber.
the letters marked thereon, A indicates asheet or body formed of intertwined sections d of coiled wire screwed one into another until a sheet of any desired length and width has been formed. The sheet is then wound spirally around a mandrel and thel adjacent edges thereof secured together by a separate section, ll, ol coiled wire being intertwined furnace with a pair of suitable tongs or a clamp, attaching the tongs or clamp to a device for drawing upon the tube and stretching it as it passes through the furnace.
Reference being had to the drawings and.
In stretching the tube it. increases in length about two and a half times, and is re duced in diameter in the same proportion. 5o The tube D is then again heated and passed between rolls to flatten it into the form shown at E in Fig. i, and produces a double belt in which all of the elongated links c cross the belt diagonally and present an unbroken and 5 5 continuous working-surface on bot-h sides and edges. By causing the links or helices to cross the belt diagonally the tensile strength of the belt is greatly increased, the tendency to stretch longitudinally and laterally over- 6o come, and a belt produced in which there are no inequalities in its strength or surface, while the grippin qualities of the belt on the pulley are appreeiably enhanced. The belt E is then tempered and may be used with or without a 65 covering, F, of rubber or equivalent material. lVhen it is desired to cover the belt, the rubber is laid npon one or both sides of the belt and passed between rolls suitably heated, and the rubber pressed into the interstices be- 7o tween the links and embedded therein..
The tube D herein shown is claimed in my application Serial No. 288,627.
Having thus fully described my invention, what I claim is-- l. \Vi1.'ebelting consisting of a double thickness or layers of intertwined elongated helices crossing the belt diagonally and present ing folded edges and a vcontinuous and unbroken surface, substantially as described.
lire belting composed of a double thickness or layers of intertwined elongated helices crossing the belt diagonally and presenting folded edges and a continuous and unbroken surface, and provided with a covering 8 5 of rubber or equivalent material. Y
In testimony whereof I affix my signature in presence of two witnesses.
THOMAS MIDGLEY.
