RIVET.
SPECIFICATION forming part of Letters Patent No. 326,100, dated September 15, 1885.
Application filed June 29, 1885. (No model.)
T 0 all whom it may concern:
Be it known that I, WILLIAM CLAXTON BRAY, of Newton, in the county of Middle sex and State of Massachusetts, have invented a new and useful Improvement in Rivets, of which the following, taken in connection with the accompanying drawings, is a specification.
My invention relates to that class of rivets which have tubular or split shanks, and are adapted to cut their way through the material in which they are to be set, and has for its object the remedying of one objection to riv ets of considerable length of this class, viz:
It has been found in practice that rivets one-half or five-eighths ot'ian inch in length and about five thirtyseconds of an inch in diameter, and having heads the outer surfaces of which are convex or raised in the center and gradually sloping to their peripheries, can seldom be driven straight through two thicknesses of solid sole or belt leather, but will be deflected to one side, the head rolling or moving in the concavcd end of the setting-plunger to permit such deflection. Heretofore in order to obviate this difficulty such extra long rivets have been made with heads having their outer surfaces flat planes at right angles to the axes of the rivets; but such heads are not as desirable as those heads having raised centers,forthe reason that they are not as strong and do not look as well, and hence the desirability of obviating the difficulty without making a'fiat head.
To this end my invention consists in a rivet having a head the central portion of the outer surface of which is raised in the center higher than at its periphery and having at its outer edge an annular fiat surface at right angles to the axis of the rivet, as will be more fully described.
Of the drawings, Figure 1 represents aplan of one form of my improved rivet. Fig. 2
represents a side elevation of the same. Fig.
3 represents a central longitudinal sectional elevation of the same. Fig. 4 represents the same rivet set; and Fig. 5 representsa modified form of my improved rivet.
In the drawings, A is the rivet, the central portion, a, of the outer surface of the head of which is made convex or higher at the center v than at the periphery, said convex or .raised surface being surrounded by an annular flat surfaee,b, in a plane at right angles to the axis of the rivetshank c, as shown.
\Vith a rivet formed as shown, and the end of the'setting-plunger being provided with a sunken recess to readily receive the convex or raised portion a, and an annular flat surface about said recess, which I flat surface shall correspond with the fiat annular surface I) of the rivet, the rivet will be forced straight through the material without deflecting to one side or the other just as certainly as it the Whole outer surface of the head were flat, and the head will resist a greaterstrain because of it greater thickness at its junction with the shank than the flat head, and at the same time it presents a much neater appearance when set than the flat-headed rivet, and therefore is more desirable.
What I claim as new, and desire to secure by Letters Patent of the United States, is-
A rivet having a head provided with an annular flat surface at its outer edge at right angles to the axis of its shank, and an elevated central portion of greater thickness than said flat surface, substantially as described.
In testimony whereof I have signed my name to this specifieation,in the presence of two subscribing witnesses, on this 27th day of June, A. D. 1885.
WILLIAM o. BRAY.
