Portable electrolytic testing device for metals

Claim 2

A self-contained portable electrolytic testing device adapted to be used for quickly determining the presence of a given metal in a variety of metal alloys and characterized in that the device is of such size and lightweight construction that it can be readily carried in the hand of a user, said testing device comprising a housing adapted to be readily grapsed and carried in a person's hand, an electrical test circuit carried by said housing and including a storage battery and positive and negative electrodes electrically connected to said battery and extending outwardly from said housing, an electrolytic solution for use with said electrodes, said electrolytic solution being visually changeable in color upon detection of the presence of a given metal, and container means for containing and dispensing said electrolytic solution therefrom in small amounts and being carried by the housing to thus provide the electrolytic solution readily accessible for use with the electrical test circuit for quickly determining the presence of a given metal in a variety of metal alloys.

Claim 3

A testing device according to claim 1 wherein said container means comprises a pliable-walled container adapted to be readily manually squeezed and thus deformed for dispensing said electrolytic solution therefrom.

Claim 4

A testing device according to claim 1 wherein said electrodes extend outwardly in a substantially common direction from said housing, and wherein said container means has a dispensing spout extending outwardly therefrom and outwardly from said housing and adjacent said electrodes.

Claim 5

A testing device according to claim 1 wherein means is provided in association with said electrodes for visually distinguishing the polarities of said electrodes from each other.

Claim 6

A testing device according to claim 1 wherein said electrodes are substantially rigid and extend outwardly in a substantially common direction from said housing, wherein each electrode includes an identifying sleeve thereon, and wherein said sleeve on one of said electrodes is of a visually distinct appearance relative to the sleeve on the other of said electrodes.

Claim 7

A testing device according to claim 1 wherein said housing is elongate and has substantially longitudinally aligned battery and container compartments therein, and wherein said storage battery is positioned in said battery compartment and said container means is positioned in said container compartment.

Claim 8

A testing device according to claim 6 wherein said container means comprises a manually squeezably deformable, pliable-walled container, wherein said container fits relatively snugly in said container compartment, and wherein said container compartment is open at one side thereof to facilitate manually applying a squeezing force to said container to discharge solution from said container.

Claim 9

A testing device according to claim 7 including a pliable strap member secured to said housing and extending across said container compartment and arranged to extend between said container and that side of said container compartment opposite from said open side of said container compartment with an end portion of said strap member extending outwardly through said open side of said container compartment so that said strap member can be grasped and pulled outwardly through said open side of said container compartment and relative to said housing for aiding in removing said container from its respective compartment.

Claim 10

A testing device according to claim 6 wherein said housing is provided with an access opening leading into said battery compartment, and door means normally closing said access opening and adapted to be opened for access to the storage battery in said battery compartment.

Claim 11

A testing device according to claim 6 wherein said electrodes extend outwardly from one end of said housing adjacent said container compartment, and a protective cap removably mounted on said end of said housing and overlying said electrodes.

Claim 12

A self-contained portable electrolytic testing device adapted to be used for quickly determining the presence of a given metal in a variety of metal alloys and characterized in that the device is of such size and lightweight construction that it can be readily carried in the hand of a user, said testing device comprising a housing adapted to be readily grasped and carried in a person's hand, an electrical test circuit carried by said housing and including a storage battery and positive and negative electrodes electrically connected to said battery and extending outwardly in a substantially common direction from said housing, an electrolytic solution for use with said electrodes, said electrolytic solution being visually changeable in color upon detection of the presence of a given metal, and container means carried by said housing and positioned inwardly from said electrodes for containing a supply of said electrolytic solution therein, said container means having a dispensing spout projecting outwardly therefrom and from said housing and between said electrodes to thus provide the electrolytic solution readily accessible for use with said electrodes for quickly determining the presence of a given metal in a variety of metal alloys.

Claim 13

A self-contained portable electrolytic testing device adapted to be used for quickly determining the presence of a given metal in a variety of metal alloys and characterized in that the device is of such size and lightweight construction that it can be readily carried in the hand of a user, said testing device comprising a housing adapted to be readily grasped and carried in a person's hand, an electrical test circuit carried by said housing and including a storage battery and positive and negative electrodes electrically connected to said battery and extending outwardly in a substantially common direction from said housing, an electrolytic solution for use with said electrodes, said electrolytic solution being visually changeable in color upon detection of the presence of a given metal, and container means carried by said housing and positioned inwardly from said electrodes for containing a supply of said electrolytic solution therein, said container means having a dispensing spout projecting outwardly therefrom and from said housing and between said electrodes to thus provide the electrolytic solution readily accessible for use with said electrodes for quickly determining the presence of a given metal in a variety of metal alloys.

Claim 14

A testing device according to claim 11 wherein said electrodes extend outwardly from said housing to a greater extent than said spout of said container means, and said container means comprises a pliable-walled container adapted to be readily squeezed manually by the user for dispensing electrolytic solution through said spout.

Claim 15

A testing device according to claim 11 wherein said housing is provided with a battery compartment for containing said storage battery therein and a container compartment for containing said container means therein, wherein said container means comprises a pliable-walled container adapted to be manually squeezed for dispensing solution therefrom through said spout, and wherein said container compartment is open along one side thereof to facilitate manually squeezing said container.
