2 SHEETS-SHEET 2- WILLIAM F. MUEHL, 0F SYRACUSE, NEW YORK;

OXYGEN-GENERATOR.

Application filed December 12, 1914.

To all whom it may concern:

Be it known that I, \VILLIAM F. MUnnL, a citizen of the United States, residing at Syracuse, in the county ofOnondaga and State of New York, have invented certain new and useful Improvements in Oxygen- Generators, of which the following is a specification.

My invention relates to a process of and apparatus for generating oxygen and supplying the same to the cylinder 01' cylinders of internal combustion engines, for removing carbon deposits therefrom.

An inu'iortant object of the invention is to provide means to generate oxygen and supply the same to the interior of the cylinder or cylinders of an internal combustion engine for removing deposits of carbon from the same in a highly ellicient manner.

A further object of the invention is to provide novel and simple electrically operated means to heat the chemical or chemicals contained within the apparatus for generating the oxygen.

A further object of the invention is to provide apparatus of the above mentioned char acter, which is portable, and having means whereby the electrically operated heating apparatus embodied therein may be readily connected with the ordinarily available source of current.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a central longitudinal sectional view through apparatus embodying my invention, parts thereof being broken away, Fig. 2 is a similar view through the chemical holding and heating apparatus, Fig. 3 is a similar view through one of the couplings, and Fig. 4 is a central longitudinal sectional view through a slightly different form of apparatus.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, (attention being called first to Figs. 1 to 3 inclusive), the numeral 5 designates a preferably vertical oxygen holding tank or shell having its lower end rigidly mounted upon supports or feet 6, as shown. Attached to the upper closed end of the tank 5 is a safety pressurerelief valve 7, of any well known or pre- Specification of Letters Patent.

ferred type. Connected with this end of the shell 5 near and spaced from the valve 7 is a compound valvc-striwture 8, having a needle valve 9, to regulate the passage of oxygen therethrough in proper amounts, and an auxiliary valve 10, which is adapted to be moved to complete open or closed positions.

' Connected with the valve-structure 8, be-

tween the valves 9 and 10, is a branch pipe 11, having a pressure gage 12 connected therewith, for indicating the pressure within the tank 5, as shown. Connected with the upper end of the valve-structure 8 is an out-' let pipe 13, for a purpose to be described.

The tank 5 is provided in its bottom with a centrally arranged opening 14, receiving an interiorly serew-threaded ring 15, having a laterally extending annular flange 16, which is bolted or otherwise rigidly attached 17 or the like.

The numeral 18 designates an oxygen generating receptacle or shell, which is substantially cup-shaped, with its upper end open and its lower end closed by a relatively thick head or bottom 19, having its exterior screw-threaded, as shown at 20, and provided with a stop-flange, as shown at 21. The head 19 screw threads into the ring 14, as is obvious, with the stop-llangc engaging the ring 15, as shown.

The receptacle 18 is heated by means of a resistance coil 22, the opposite ends of which are connected with wires 23 and 24. The wire 24 is electrically connected with a screw-threaded sleeve-terminal 25, While the wire 23 is electrically connected with an end-terminal 26, connected with and insulated from the head 19, as shown.

The numeral 27 designates a socket of the ordinary type, adapted to be screwthreaded into the sleeve-terminal 25, whereby the terminals of the socket have electrical engagement with the terminals 25 and 26, for completing the circuit, as is well known. Connected with the pipe 13 is a pipe 28, having connection with an oxygen distributing shell. having branch pipes 30 connected therewith, the same being adapted for connection with the several cylinders of the engine. Connected with the outlet end of each branch pipe 30, as shown in Fig. 3, is a valve-controlled coupling 31. This valve-controlled coupling comprises a .casin 32 having screw-threaded en a 'e- 7 L: b b

ment with a sleeve 33, apertured for receivv screw-threaded spark-plug receiving1 'tube is formed of ing a tube 34, provided with a flanged head 35. In this manner the shell 31 has a swiveled connection with the tube 34, and forms a gas tight joint therewith. The tube 34 is suitably connected with the outlet end of the pipe 30, as shown. The tube 34 has its outlet end internally screw-threaded, for receiving a screw-threaded sleeve 36, having engagement with a coil spring 37, engaging a ball-valve 38, adapted to engage and disengage a valve seat 39. This ballvalve opens downwardly to permit of the free passage of the oxygen into the casing 32, but automatically seats upon the passage of the oxygen or other gases in a reverse direction. The shell or casing 32 has its free end screw-threaded, as shown at 40, and is adapted to be inserted within the opening of the cylinder of the engine. e shell 32 is provided with a transverse opening 41, receiving a rotatable valve 42, by means of which the supply of oxygen into the cylinder may be regulated, and completely out ofi when desired.

The form of apparatus shown in Fig. 4, comprises a tank 44, closed at its bottom and provided at its top with a large screw threaded opening 45, engaging with a removable screw-threaded cap or plug 46, as

shown. Attached to the lower side of the cap or plug 46 and depending therefrom is a tube 47,. to which is secured a chemical receiving and heating receptacle 48, clamped thereto by means of a nut 49, having screwthreaded engagement with the tube. This insulating material a and receives lead wires 50, the lower ends of which pass out through apertures in the tube 47 and have electrical connection with -a heating coil 51, surrounding the tube 47 within the shell 48. This heating coil 51 is preferably surrounded by a protecting casing 52. The lead wires extend into a stationary socket element 53 and are there connected with the socket element terminals.

current. The cap or head 46 has connection with a gas outlet pipe 55,- communicating with the interior of the tank 44 through a port 56 or the like. This pipe 55 has a cut-off valve 57 connected therein. The pipe 55 is connected with the pipe 28, which is adapted to be connected with the as already described. Connected with the pipe 55 inwardly of the cut-off valve 57'is a branch pipe 59, having a pressure gage 60, as shown.

. In the use of the apparatuses, in practising the process, the chemical or chemicals generatlng the outer tank. The current is for heating the receptacle wherethe. same being placed in turned on by the oxygen is liberated, heldwithin the outer tank.- It is preferred to generate the oxygen while the same is being used'in order that it may be supplied to the cylinder or cylinders, in a warm condition. I have found that the oxygen is very effectual in removing carbon.

It is to be understood that the forms of my apparatus shown and described are to be taken as preferred examples of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from invention or the scope of the subjoined claims.

Having thus described my invention what I claim is the spirit of the.
