l Application led May 22,
Box, of which the yfollowing is a specification.- f
My invention relates particularly to a construction having a hinged cover, and has f or its main object the provision of a special hinge which can be economically made, and
. shown at 18 in Fig. 3 with a loop 14. The' which affords a secure and durable connection between the cover and the body of the box.`
Figure 1 is an end view of an inclosed switch construction embodying the improve- .ments of my invention.
Fig. 2 1s a perspective view of the box, part of the cover being broken awafy'.
Fig. 3 is a perspective view of a ragment of one side of the box showing one step in the formation o'f a hinge.
Fig. 4 is a fra entary sectional view showmgtheinetho of connecting the parts of the hinge. l
Fig. 5 is a similar Iview showing the completed hinge with the cover open.
Fig. 6 is a fragmentary sectional view showing the cover closed.
Fig. 7 -is a horizontal sectional view showing one method of securing lone of the hin ed parts in place. l
he box has a body portion 10 and a cover 11 suitably intertting .and inclosing a switch 12 of any suitable typeadaptedto be operated by an external handle 13.
The hinge 1oop-14 pro'ects outwardly `from the side ofthe box. an embraces a bar portion 15 carried by the coverand formed of the flange 17. The hinge loop is formed by shearing or cutting a strap 1n the form ends of the straps 18 are then inserted` in the openings 16 inf the flange of the cover and each strap is then bent into the position shown in Fig.- 5.
When the cover is closed, it will be seenthat theupper end of the strap l18 is like- Speccation of Letters' Patent. I

wise inside of the flange '17 as shown in Flg. 6 so that it is impossible to bend or pry open the loop 14 to release the hinge. I prefer to provide a flange 19 along the edge gf' the cover opposite the` hinges as shown in Additional security may be provided by fastening the upper end of each strap 18 to l the adjacent portions of the side of the box as by means of spot welding or by displacing the metal as shown at 2O and 21, or by both. displacing the metal and welding. In view of the fact that the bar 15'is interposed beneath the loop 14, it is obviously more irn-A portant to prevent the strap 18 from being pulled outward than it is from being pushed inward. n
The preferable method of securing the end of the strap in the slot is shown in Fig. 7. It will be understood that the strap 18 is the same width as the opening from which it is sheared and-after the cover has been located on the strap, the end of the latter is forced back into the opening and the metal of the strap 18 with the sideof the box 10, but' it will be understood be employed.
1. In an electric cut outbox, a metal box bod member, and a metal cover member for saidy box body member, one of said members having a pintle thereon, the other of said members having slits therein, and the metal between said slits displaced to form a hinge tongue loop for receiving said pintle and hinging the cover to the box body, the metal on a part adjacent one of said slits being displaced and forced over the metal on the part opposite the other part and adjacent the Ithat other methods may secured and the disengagement of the box body and cover prevented.
2. In an electric out out box, a metal box 5. body, an integral. tongue formed on said body, said tongue being bent to form an outwardlyfextending lhinge loop, and a metal cover for said box body having aslot therein for receiving said tongue, the edge of the cover adjacent said slot constituting a pintle (3o-acting with said hinge loop for hinging said box body and cover together, the .free end of said tongue being secured to said box body, whereby the tongue is prevented from being displaced fromthe box body.
