Description

June 14, 1955 w. A. PARDEY 020m: MAKING MACHINE Filed Nov. 25, 1952 2 Sheets-Sheet l INVENTOR.

WILLIAM A. PARDEY ATTORNEY United States Patent 'Qfiice 2,710,835 Patented June 14, 1955 My invention relates to electrical terminals which are particularly adapted to be applied to ozone making tubes used in ozone generators.

The primary object of this invention is to provide an electrical terminal comprising a multiple of sockets adapted to receive the electrodes of ozone making tubes,

the said multiple terminal possessing flexibility, eliminating mechanical strain between the sockets and tubes in the tube assembly.

Another object of the invention is providing a tight fitting socket for receiving the tube wherein ozone vapors are prevented from reaching the electrodes of the tubes, the material from which the terminal is made providing a complete insulator against ozone vapors.

A still further object of my invention is the provision of a bus bar within the terminal adapted to receive the electrodes of the ozone tubes wherein each electrode adjusts itself to the bus bar, making a complete electric contact.

Another object of my invention is to mount the ozone tubes in a self-contained grid that can be operated remotely from the base of the machine containing the transformers and control switches.

These and other incidental objects will be apparent in the drawings, specification and claims.

Referring to the drawings:

Figure 1 is a perspective view of my new and improved ozone making machine.

Figure 2 is a perspective view of the machine, having the grid of ozone producing tubes removed therefrom for remote operation.

Figure 3 is a perspective view of the grid of tubes removed from the base of the machine.

Figure 4 is a detail of the terminal for receiving the ozone tubes.

Figure 5 is a side view of the assembled machine, having the side wall broken away for convenience of illustration, taken on line 5-5 of Figure 1.

Figure 6 is a plan view of one end of the tube grid assembly, taken on line 6-6 of Figure 3, parts broken away for convenience of illustration.

Figure 7 is an end sectional view, taken on line 77 of Figure 6, looking in the direction indicated.

Figure 8 is a sectional view, taken on line 88 of Figure 1, looking in the direction indicated.

Referring more specifically to the drawings:

My invention resides in the tube grid assembly, particularly in the electric terminal mb1y 1, which is adapted to receive the electrode ends'2 of the ozone making tubes 3. The terminal and tubes are mounted. within the housings 4 of the grid assembly. The housings 4 consists of box-

like closures

5 and 6 coming togetlierat 7 and being clamped together by the screws 8,: "j

Oppositely disposed at the ends. of the ozone'tubes 3, and running transversely of the housings 4, are

ribs

9 and 10. These ribs not only strengthen the walls of the housings but they act as clamps for holding the ends of the tubes within the housings. Bridging the tubes and spacing them are relatively soft pads 11. These pads are disposed between the ribs 9 and the tubes, as best illustrated in Figures 7 and 8.

The terminal 1 consists of a flexible tubular body 12, having sockets 13 formed thereon. Located throughout the length of the body 12 is a metallic tubular bus bar 14. High tension electrical energy is delivered into the bus bar by way of the conductor 15. The wire 16 of the conductor 15 is inserted into the tubular bus bar 14, after which the bar is crimped as indicated at 17, holding the wires 16 of the conductor 15 within the bus bar. Both the bus bar and the conductor being embedded within the body 12 of the terminal 1.

The terminal 1 is made of a material that is flexible and at the same time of a material that will resist oxidization existing where ozone is being created. The usual metallic cup or plate 18 is connected to the electrode 19 by the connecting wires 20. The ends 2 of the ozone tubes 3, together with the electrodes 19, fit snugly within the socket 13, preventing any ozone from reaching the electrodes.

The electrodes are formed in the shape of springs so that they will bear constantly against the bus bar 14, insuring a good permanent contact of each tube individually from the other. The sockets 13 of the terminal are clamped between the

cross ribs

9 and 10 of the

closures

5 and 6, supporting the said terminal within the housings 4.

I have designed electric terminals for grids of ozone making tubes that prevents ozone from reaching the metallic parts of the grids, also protecting the operator from electric shocks. The case 21 of the ozone unit is made of insulating material, and of a pleasing design and houses the usual high tension transformer 22 therein,

having a control switch 23 mounted therein for controlling the operation of the unit.

One of the outstanding features of my invention is the fact that the ozone making tubes are mounted within a complete grid separate from the main machine, as best illustrated in Figures 2 and 3. By this arrangement ozone can be produced in locations that would otherwise be injurious to transformers or other parts of the machine, such as refrigerators and the like.

The grid is mounted to the top of the case, as best illustrated in Figures 1, 5 and 8, and is held thereon by the dowel pins 24. The pins 24 and feet 24A register with the holes 25 formed in the top of the case 21.

What is claimed is:

1. An ozone producing grid assembly comprising a plurality of ozone making tubes disposed in parallel relation and each having an electrode at one end thereof, a terminal member shielding and in electrical contact with said electrodes, said terminal member including a tubular body of flexible insulating material that is resistant to oxidation; said tubular body having spaced sockets opening therefrom, and a bus bar mounted longitudinally within said tubular body and exposed through said sockets, said sockets being of a size snugly receiving the ends of said tubes with their electrodes in contact with said bus bar.

2. An ozone producing grid assembly as defined in claim 1 comprising a housing enclosing said terminal member and having top and bottom bridges transversely spanning said tubes, and cushion strips on said bridges and engaging said tubes.

3. An ozone producing grid assembly as defined in claim 2 in which said tubes are alternately disposed in opposite relation, one of said terminal members at each end of said tubes with sockets nesting the ends of alternate tubes, and one of said housings at each end of said tubes.

4. An ozone producing grid assembly as defined in claim 1, wherein said electrodes comprise springs which are under compression in engagement with said bus bar.
