?atented April 6, 1909.
Application filed April 15, 1908. Serial No. d27,2s8.
To all "whom it may concern:
Be it known that I, l nens Enwnnn lonsnLL, a citizen or" the United States, residing at Attleboro, in tire county of Bristol and State of lilassachusetts, have invented a new and useful Improvement in Spring Ring ns, oi Wl'llCl'l the following is a specification.
This invention has reference to an improvement in spring snaps and more particularly to an improvement in spririn snaps.
The ob ect of this invention to improve the construction of a spring ring snap, whereby the bolt stop, the means for operating the bolt and the eye member for attaching the snap are formed in one, integral with the bolt and the whole constructed without solder.
My invention consists in the peculiar and novel construction of a spring ring snap hav ing the attaching eye member on the bolt and other details of construction, as will be more fully set forth hereinafter and claimed.
Figure l is a face view of my improved spring ring snap, showing the same n the c osed position. 2 is a sectional view, showing the snap in the open position. Fig.
3 is a face view of the double bolt blank struck from sheet metal. Fig. 4 is a face view of the i iished double bolt blank, and Fig. 5 is iace view of the fmished double bolt blank cut in halves to form two bolts.
In the drawings, indicates a tubular ring, b a semi-circular bolt adapted to have a sliding fit in the tubular ring, 0 an attaching eye member, and (Z a coiled spring in the tubular ring. The tubular ring a has an opening 6 forming the open ends 7 and 8 an d a bent-in tongue 9 adjacent the end 7 and forming a stop for the adjacent e116 ol the coiled spring cl, as shown in Fig. 2. The semi-circular bolt Z) has the ends 10 and 11 and the outwardly-extending attaching eye member 0 in the form of a ring adjacent the end 11. The attaching eye member 0 is formed integral with the bolt b by first stamping out a double bolt blank from sheet metal, as shown in Fig. 3, rounding the same in finishing dies, as shown in Fig. 4, and then cutting the same in halves, as shown in Fig. 5.
l l i l l I i l l The coiled spring dis placed in the tubular ring a intermediate the bent-in tongue 9 and the end 10 of the bolt 1), as shown in Fig. 2. The snap is opened by the attaching eye member 0 which new acts as a bolt lznob and as a stop to limit the opening movement of the bolt against the tension of the coiled spring d and when released closes by the eX- pansion oi the spring d. The end 11 of the bolt enters the end 7 of the tubular ring a when closed and the eye member 0 new acts as a stop on the end 7 to limit the closing movement of the bolt. The snap is secured to a chain or other article by the eye member c.
It is evident that the eye member 0 may be in the form of a ring secured to the bolt 6 which may be termed of wire without materially affecting the spirit of my invention.
Having thus described my invention, I claim as new and desire to secure by Letters Patent;-
1. A spring ring snap consisting of a tubular ring having an opening and a bent-in tongue forming a stop, a semi-circular bolt in the tubular ring, a coiled spring in the tubular ring intermediate the bent-in tongue and the end oi the bolt, and means for opening the bolt, for limiting the opening and closing movement of the bolt, and for attaching the snap, consisting of an eye member formed integral with the bolt.
2. A spring ring snap consisting of a tubular ring having a art thereof cut away, a tongue struck out Mom said ring and bent so as to lie on the interior thereof, a semi-circular bolt in said ring, a coiled spring in the ring engaging said tongue and one end of said bolt, and an eye member on said bolt operating in said cut-away portion of the tubular ring, said eye member being adapted for engagement with the ends of the ring to restrict the opening and closing of the bolt, and being designed to receive fastening means.
3. A spring snap consisting of a tubular ring, havin a cutaway part forming two spaced ends, a spring pressed bolt 0 erating in said ring and across the space between said ends thereof, and a combined stop and fastening member carried by said bolt adjacent one of its ends, said member operating name to this specification in the presence of 1n said space between the ends of said ring tWo subscnhlng Witnesses.
and being adapted for engagement with said I T ring ends to restrict the opening and closing FEARS W D 5 of said bolt, and being formed to engage fas- Witnesses:
