SLEEVE-NUT AND THE METHOD OF MAKING SLEEVE-NUTS.
SPECIFICATION formingpart of Letters Patent No. 236,723, dated January 18, 1881.
Application filed September 9, 1878. I
To all whom it may concern:
Be it known that 1, GEORGE H. SELLERS, of the city of WVilmington, New Castle county, and State of Delaware, haveinvented anew and Improved WVrought-Iron Sleeve-Nut, of which improvement the following is a specification.
Myinvention relates to that class of wroughtiron couplings which connect tension-bolts, such as are used in bridge and roof and other trusses and it consists of a right-hand nut, a left-hand nut, and the sleeve proper which unites the two nuts, the length of this intermediate sleeve being proportioned to the amount of adjustment required. Such sleeve- :5 nuts have heretofore been constructed, so far as I know, in two forms-one with the sleeve cylindrical inside and outside, and the nuts hexagonal at the ends, enlarging toward and vanishing in the round sleeve, the other with hexagonal exterior and parallel sides from end to end, and the interior of the sleeve cylindrif cal. Both these forms have the end sections thickened up to receive the thread. In both of these forms there isa surplus of metal which is necessarily unequally distributed, producing unequal sections longitudinally, so that this surplus gives additional weight without additional strength, and requires a corresponding increase in the other parts of the structure to 0 sustain it. With the cylindrical sleeve the tapered hexagonal ends afford a very insecure hold for the wrench required to adjust the nut, and the hexagonal sleeve with parallel sides from end to end gives a clumsy appearance to 3 5 the structure with the largest surplus of metal.
It is the object of my invention to furnish a wrought-iron sleeve-nut having the sleeve with a polygonal exterior and a polygonal or cylindrical interior uniting cylindrical nuts of a diameter less than that of the sleeve, the thickness of metal in the longitudinal section being as nearly uniform as is compatible with proper bearing-surfaces for the wrench, thus affording a wrought-iron sleeve nut with no surplus metal, and with an outline architecturally correct.
In the accompanying drawings, which form part of this specification, Figure 1 is an exterior longitudinal view of my improved sleevenut. Fig. 2 is a cross-section upon the line a b, Fig. 1, representing a cylindrical interior to the sleeve. Fig. 3 is a similar section representin g a hexagonal interior to the sleeve conforming with the exterior. Fig. 4 is a longitudinal section of the sleeve-nut on the line 0 d, Fig.3.
I make these sleeve-nuts from wrought-iron plates, cut to proper lengthsand widths, according to the size required, so that each plate will make a sleeve nut. These plates are heated and bent so as to form a cylindrical tube. They are then brought to a welding. heat and forged upon a mandrel in dies which give to the'whole exterior the form desired in the finished sleeve properthat is, the central section. Ihe diameter of this mandrel should be such that the interior of the sleeve will be larger than the bolts which are to be connected, and the shape of the mandrel that of the desired interior form of the sleeve. When the tube has been thus formed in the forging-dies, the section of metal on any line parallel with theaxis \villbe uniform throughout. Themandrel is then removed and a smaller cylindrical mandrel of the diameter required for the hot tom of the thread of the bolt is placed in this tube, both ends of which, at the same heat, are
now forged in dies having cylindrical ends of the outline desired for the nuts, and with the center cut out, so as not to touch that part of the tube which constitutes the sleeve. This forging will reduce the hole at both ends of the tube to the proper diameter, slightly increasing the section of the metal in the ends without materially affecting the shape or sec- 8 5 tion of the sleeve, so that the section of metal remains nearly uniform throughout. To correct any slight defect the sleeve should be returned to the dies which first formed it, where a few blows ot' the hammer will complete the 0 forging operation. The right and left hand screw-threads are then cut in the ends, and the sleeve-nut is complete. All of these operations severally are well understood, and I have given the above description as the best 5 method known to me for making my improved sleeve-nut, and not as intending to claim as new any one of the several forging or shaping operations mentioned independent of the others; but I do not confine myself to this par 10 ticular mode of forging this sleeve-nut from a single plate, as it may be done by forging two halves of the tube to the proper shape, and then weldin g them together on the smaller 5 cylindrical mandrel mentioned; or the preliminary tube may beformed of two or more pieces and then welded and shaped, as hereinbefore described.
Having thus described the nature and 0b- IO ject of my invention, What I claim as new, and
desire to secure by Letters Patent, is-
1. The process substantially as hereinbefore described, of making a Wroughtiron sleeve-nut by forging a tube in polygonal dies and upon a mandrel of the desired shape, and 15 then forging the ends in cylindrical dies upon a smaller mandrel.
2. A wrought-iron sleeve-nut made by forging a tube in polygonal dies and upon a mandrel of the desired shape, and then forging the 20 ends in cylindrical dies upon a smaller mandrel, substantially as and for the purposes described.
