Application April 21, 1952,-Seria'l No. 283,435
6 Claims. 1 This invention relates to new and useful improvements in safety fuses and adapters for electrical appliances.
More particularly, the present invention proposes the construction of an improved fuse holding unit which can be inserted in and removed from standard plugs, fittings-and adapters easily and quickly to provide them with replaceable fuses as a protection in the circuits in which they are used.
The present invention provides a means for protecting the electric circuit from short circuits and the like which may occur in the particular electrical appliance which is connected in the circuit.
Another object of the'present invention proposes forming a fuse holding unit which is interchangeable withpresent center pieces in the insertion end of an ordinaryplug, fitting or adapter to make the conversion ofthe sameto a fuse bearing structure simple and. inexpensive.
Still further; the invention'proposes constructing the fuse holding unit so that a'fuse will be 'fi'rmly held in circuit with'one of the current "*carryinggelements of a plug, fitting or adapter whenthe unit is in place yet readily removable .terial part of this disclosure:
Fig. 1 is a perspective view of a pull chain plug, fitting or adapter for an electric light socket with the ordinary center piece in its socket insertion end removed and a fuse holding unit constructed in accordance with the-present invention with a fuse therein shown ready for insertion.
Fig. 2 is a vertical section of the structure shown in Fig. l with the fuse holding unit and fuse in place.
Fig. 3 is an exploded perspective'view of the fuse holding unit and fuse shown in Figs. 1 and 2.
Fig. 4 is a vertical section of the fuse holding unit shown in Figs. 1 to 3.
Fig. 5 is a perspective view of anothertype plug and illustrating amodifica'tionbfthe fuse holdingunit.
Fig. 6 is a side view'of the structure shown in Fig. 5 with part broken away and in section.
Fig. '7 is a vertical section of the fuse holding plug shown in Fig. 6 taken at a right angle thereto.
Fig. 8 is a perspective view of a double socket plug with another modification of the fuse holding unit and fuse shown therein.
Fig. 9 is a side view of the structure shown in Fig. 8 with parts broken away and in section.
Fig. 10 is a vertical section of the fuse holding unit shown in Fig. 9 taken at right angles thereto.
Referring to Fig. 1, a chain pull electric light socket plug I0 is shown, having a threaded plug or socket insertion end H, a socket end I2 with side plug-in outlet faces l3 and a pull chain 14. The usual center section (not shown) at the insertion end ll of plug'lil has been omitted either having been removed or not inserted in assembling the plug.
In its place and interchangeable with it is shown a fuse holding unit [4 constructed in accordance with the present invention.
Preferably, fuse holding unit [4 is of the same shape and size as the common center piece it replaces. It has a body portion l5, generally cylindrical, and an outer end or face [5 with an inner end or face I1. Adjacent the inner end or face I! are wedge shaped bevelled side portions i8 and I9. The faces or ends l5 and I! preferably are fiat but the inner or upper end It may have an offset 29 in its face to provide for an easier purchase in removing the unit from a plug.
The upper end or face l6 has a fuse opening 21 through its center running axially of the body 15 toward the lower end or face H and forming a chamber within the body adapted to receive and hold a fuse 22.
The fuse 22 should not be less than 8 amperes of a common type having terminals 23 and 24' (Fig. 3) connected by a thin metallic fuse strip 25 and separated by a glass tube 28 encasing the fuse strip.
Chamber or opening 2| for fuse 22 is of a depth to seat the fuse with only the upper portion of terminal. 23 extending above the end or face it of the fuse holding unit for contact with a current carrying member (not shown) within the electric light socket into which end I I of plug H3 is screwed.
The other end I! of the fuse holding unit it has a central egress opening 2'. (see Fig. 4) connected'with andof smaller diameter thanthe chamber oropening 2| for fuse 22. This inner end I! of the'unit i4 is positioned to fit over and 3 permit a. conductor 28 to extend through the egress opening 21 to contact the lower terminal 24 of fuse 25 when the fuse is seated in. chamber or opening 2|.
Conductor 28 preferably is the threaded rod or screw generally contained in this type plug. The other end of conductor 28 contacts current carrying members 29 and 30 of the plug. Member 30 is connected with a similar member 30 in the socket end |2 of the plug through the pull chain operated mechanism 30, well known in the art.
The fuse holding unit I4 is made of non-conducting material and may be made of any of the well known insulators such as plastic, glass or porcelain. It may be made of transparent material with the fuse 22 press fitted in its opening or chamber 2|. When molded in large lots of plastic material, the unit I4 may be made cheaply enough to be discarded with a spent fuse. If desired, however, the fuse may have a loose fit in the unit for replacin the fuse in a unit with a new one.
In one side of the body a recess 3| is formed to permit the other current carrying member 3| of the plug ID to extend through and reach the socket insertion end ll.
Fig. 5 shows a socket and attachment plug 32 similar to that shown in Figs. 1 and 2 but without the pull chain feature. Plug 32 has a screw threaded plug end 33, a socket end 34 and two plug-in attachment faces 35 and 36. Its ordinary center piece at the plug end 33 has also been removed or omitted and in place thereof a fuse holding unit 31 with a fuse 38 is shown.
Fuse holding unit 31 is a modification of unit |4, being modified as shown in Figs. 5 to 7 inclusive, as will now be described. Fuse holding unit 31 is generally rectangular in shape having an elongated body 39 with opposed flat ends or faces 40 and 4|.
Face 40 may be provided with an offset portion 42 also for ready removal of the unit from a plug. Face or end 40 has a central fuse opening or chamber 43 (see Fig. 7) adapted to receive fuse 3B and running axially of the body 39 toward the other end or face 4|.
Face 4| also has an opening 44 of smaller diameter than the fuse opening 43 running axially of the body 39 and connected with the fuse opening or chamber 43. This opening 44, forms an egress from the chamber 43 so that a conductor may contact one terminal end of a fuse in the fuse opening 43 yet extend out of t e fuse holding unit. Preferably. egress o ning 44 is threaded and a screw conductor 4'5 extendable through the opening is provided. screw conductor 45 contacts one terminal end of a fuse 38 in fuse holding chamber 43 and also contacts a current carrying member 46 of the plug. The fuse holding unit 31 may also be provided with a recess along one side to allow the other current carrying member 41 of the plug to reach the threaded plug end 33 of the socket and attachment plug.
Figs. 8 to inclusive illustrate another common type plug, a double socket plug at, having a screw plug end 49 and a bifurcated body 59 with two sockets 5| and 52. The usual center piece has also been removed from the screw plug end 49 of this plug and in its place a fuse holding unit 53 has been substituted.
The fuse holding unit 53 is made of non-conducting material having an elongated body 54 with two opposed ends or faces 55 and 56. A
fuse holding opening or cavity 51 is provided in the outer or upper face 55 extending axially of the body into the body for a distance slightly less than the length of a fuse 5B containable therein.
The body 54 has two wedge shaped beveled sides 59 and 60 adjacent the lower or inner face 56.
A central opening 6| is provided in the lower face or end 56 running axially of the body and connected with the fuse holding chamber or opening 51 to provide an egress therefrom. Opening BI is smaller in diameter than the fuse opening 51 however so that a fuse 58 in fuse opening 51 cannot fall through the egress opening 6|.
A clip conductor 62 having a head 63 adapted to fit in the fuse chamber 5'! and to bear against the bottom 64 of the chamber and legs 65 and 66 attached to the head and adapted to pass through the egress opening 6| is provided. The legs 65 and 66 have their free ends oppositely bent to lie against the lower face or end 56 of the fuse holding unit 53.
Thus when the unit 53 is inserted in the plug end 49 with a fuse 58 in the fuse chamber 51 of the unit, the head 63 of the clip conductor 62 will be in contact with one end terminal of the fuse and the legs 65 and 66 of the clip will be in contact with current carrying members 61 and 68 in sockets 5| and 52 of the double socket plug 49. The other current carrying members 69 and 10 extending to the threaded plug end 49 of the double socket plug will lie flush with the sides of the fuse holding plug.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
