Letters Patent No. 66.366, dated July 2, 1867'.

IMPROVEMENT IN LAMP-SHADE CLASPS. v

t'tlp fitlgohnle referral in in 111m letters patent and making and at flgc same.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, J. J. MARCY, of West Meriden, in the county of New Haven, and State of Connecticut, have invented a new Improveinent in Shade Clasp; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the. same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a side view of the clasp-complete.

Figures 2 and 3, the two parts detached; and in Figure 4, a vertical central section.

This invention relates to an improvement in the construction of the clasp used to attach shades to lamp chimneys; and consists in the arrangement of the springs which sustain the clasp upon the chimney so that they p also serve ,as a spring to secure the outer ring upon the, shade so as to secure the shade to the clasp; and in order to the better understanding of my inventiomas well as to enable others to construct the same, I will proceed to a description as illustrated in the accompanying drawings. i l

i A is ametallic conical ring, to which are fixed three springs, B B B, extending above and below the ring A, so as to bear upon the chimney upon points above and below. 0 is the outer ring, seen detached in fig. 2. The springs are formed so that at the point a, (seefig. 4,) they project beyond the upper edge of the ring, and I are attached to the ring A at a point, cl, below the upper edge, so that the upper end of the spring may be bent forward so as to bring the shoulder a of the spring within the circumference of the ring A. The shade, denoted in blue, fig. 4, is placed over the ring A, and so as to bear upon its outer surface; then the ring 0, the internal diameter of which is a little more than the external diameter of the ring A, is placed on over the springs on to the shade and pressed down, passes over the shoulder a of the spring, (the spring yielding'for this purpose) as seen in fig. 4, and is there held firmly upon the shade by the projections a returning over theupper edge of the ring 0. If occasion require to renew the shade, depress the springs so that the outer ring 0 may be removed, then a new, shade may be placed thereon as before.

Having thus fully described my invention, what I- claim as new and useful, and desire to secure by Letters Patent, isb The combination of the two rings A and G with the springs B, when the said springs B are formed so as to hold the ring 0, substantially as and for the purpose specified.
