Yanimi sans @sind @Mira H'ORAGEYG. ALEXANDER, OFNEW YORK,
Letters Patent No.'105,157 dated July 12, 1870.
IMPROVEMENT IN SAFETY-CAPS P OR CANS.
'i'he Schedule referred to in these Letters Patent and making part of the same accompanying drawing forming part of this specifica tion.
Figure lis a top view of my improved cap.
Figure 2 is a detail sectional view of the same, takenthrough the line x x, g.l 1.
Similar letters ofreference indicate corresponding parts.
My invention has for its object to improve the construction of safety-caps for cans, so as to make lthem neater in appearance and .simpler in construction, while being equally effective in use; and
It consists in the construction of the ears or catches by means of which. the upper part is secured to the lower part of said cap, as hereinafter more fully described.
A is the lower part ot' the cap, the'base flange of which is designed to be securely soldered to the top of the can, directly over the orifice or opening through vthe top of said can.
The part A is made of a disk of metal, in the center of which is struck-up a tubular socket, the sides of which may be straight or slightly tapering.
a are the ears, catches, or fastenings, which are formed by striking up small portions of the base flange of the part A at the same time that the central tube or socket is formed. A A gauge is then inserted between the' projections a and the central socket, and
the said'projeotions are pressed downward and inward, bringing them into such a form as to receive the edges of the base flange of the upper part B. 4
The edges of the base flange of the upper part B may be trimmed oh" upon the opposite sides of the central socket, as shown 'in iig. 17 to enable said flange to pass down between the ears or catches a", or the said edges may be slightly notched to pass over the said catches, or they may be out slightly inclined or cam* shaped for the saine purpose, the part B in either case being secured in place by turning its edges beneath the inner projecting parts of the projections a' of the part A of the cap.
When the metal of which the cap is made is very light, the process of forming the projections a' may crack or break the metal, s o that the volatile party of the oil might esca-pe through it. To guard against the possibility of this, I drop a drop of solder into the cavities in the under side of the base ange ofthe said part A, formed by striking up the' metal to form the catches or vears al.
Having thus described my invention, I claim as new'and desire to secure by Letters Patent The ears or catches a', formed by striking upv the solid metal of the base flange vof the part A of the can-cap, and pressing the projections thus formed downward and inward, substantially as herein shown and described, and for the purpose set forth.
'.lheabove specification of my invention signed by me this 7th day ot' June, 1870.
HORACE 0. ALEXANDER.
