CLASP FOR BOXES, etc.

SPECIFICATION formingpart of Letters Patent No. 433,240, dated July 29, 1890.

Application filed January 2, 1889. Serial No. 295,182. (No model.)

T0 (423 whom it may concern.-

Be it known that I, THEODORE M. HASS, of New York city, in the county and State of New York, have invented a certain new and useful Improvement in Clasps for Boxes, &c.; and I declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to an improvement in the manufacture of light clasps for boxes, &c.; and the invention consists of a box-clasp constructed, combined, and arranged in the manner hereinafter shown, described, and claimed.

In the accompanying sheet of drawings, Figure l is a face view of the clasp applied to a box; Fig. 2, a horizontal section in the plane :0 at, Fig. 1; Fig. 3,avertieal section in aplane passing through the center of one of the studs. Figs. 4 and 5 are a side elevation and vertical section, respectively,of the studs. Fig. 6 is aview of the blank from which the studs are formed.

Similar letters of reference indicate like parts in the several views.

Clasps intended to be applied to light fancy boxes-such as stationery and glove boxesmust from necessity be light, neat, and inexpensive, but of course sufiiciently strong to render them effective and durable. Clasps of this description are constructed with a baseplate A, to which heretofore studs have been riveted, the studs being made of solid metal, with their ends passed through the base-plate and by a hammer upset and riveted to the plate. In each stud was drilled a hole for the insert-ion of the pivots of the tongue B of the clasp. This manner of making the studs is expensive in material and manipulation, for each stud had to pass through a milling-machine and be drilled and finally riveted. To save this expense and to make studs equally strong and in some respects better than the ones of solid metal above mentioned,I form these studs by first making a blank 0 of the shape shown in Fig. 6, and by the aid of suit able dies and a press draw the blank into the tubular form shown in Fig. 4:, and when the blank is so drawn a stud D is completed, with a hole 22 formed therein and with lugs 0 projecting therefrom, so that the stud may be at once secured to the base-plate A by inserting the lugs c in corresponding slots in the baseplate and clinching the lugs on the under side of that plate, the pivots of the tongue B finding suitable hearings in theholes b, and being in that way united to the studs and the baseplate.

It is obvious from the construction of the studs of my clasp that less weight of metal is required and the manipulation cheapened without in any manner lessening the elfectiveness of the studs. Besides, the tubular studs in this way made are susceptible of a higher degree of finish than are the solid studs before mentioned, since the crown d of the tubular studs is left in a smooth and rounded condition by the action of the dies in which the studs are formed, while the crown of the solid studs, unless afterward filed and burnished, is too rough to take a bright polish.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of the tubular studs D, each formed from a flat blank having lugs c and attached to the base A and having a hole 11 therein, a tongue B, pivoted to said studs, and a part to engage the tongue, as and for the purpose described.
