Application filed September 3, 1914.

To all whom it may concern:

Be it known that 1, JAMES R. BURKHARDT, citizen of the United States, residing at Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Valves, of which the following is a specification.

y This invention relates to valves, and more particularly relates to valved devices adapted to be interposed at some point in the fuel pipe leading from a source of supply to its point of consumptionso that means will be thereby provided to govern the passage of the fuel.

As a principal object, this invention contemplates the provision of valved means of the character described which shall be so constructed as to form a continuous passage from the gasolene tank to the motor of a combustion engine only when properly set in a predetermined position, knowledge of all which is available only to the rightful op erator.

A further object is to provide in a valve of the type set forthpermutation means whereby the predetermined set position of the valve may be varied at will and to also provide means whereby the person having knowledge of the correct combination may easily manipulate the valves to assume the proper position without the aid of tools.

A still further object is to provide means connected with a valve of the foregoing species which shall reliably prevent fraudulent tampering with the mechanism with an idea of preventing proper operation of the valve and to locate the actual working parts at points practically inaccessible to any unauthorized person while situating the controlling means at a pointwhich may be found to he most desirable for the ready operation of the owner.

Anobject of equal importance with the foregoing is to so construct a valve of the class described andinparticuhuto pay such regard to theproportion, number and arrangement of parts as to render it capable of being cheaply manufactured, readily installed, durable and eflicient in operation.

The above and additional objects which will become apparent as this explanatory description proceeds are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are ap- Specification of Letters Patent.

part of this appllcation.

With reference to the drawings, wherein there is illustrated the preferred embodiment of this invention it is reduced to practice, and throughout the several views of reference designate similar partsz'lligure 1 is a sectional View taken through an automobile fuel tank showing the novel valve comprehended by this invention positioned therein and connectcd to the customary fuel pipe, Fig. 2 is a sectional view taken on the plane indicated by the line 2'2 of Fig. 1, Fig. 3 is a transverse section of a portion of the fuel tank as indicated by the line 33 of Fig- 1. Fig. a is a sectional View showing the device suitably positioned upon any desired support and interposed between spaced sections of the fuel pipe, Fig. 5 is a plan view of the permutation dials, parts being broken away, and Fig. 6 is a. transverse sectional view taken on the plane determined by the lines 66 of Fig. 4. There is illustrated in Fig. 1 a fuel tank 10 such as is to be found upon every gasolene driven vehicle in the bottom of which is formed the rectangular-offset portion 1-1 of such size as to readily receive therein a casing '12 longitudinally bored as indicated at 13 and provided with enlarged valve seats 14in which are seated rotary valvcs15 severallybored as denoted by the numeral 16 in order to permit each of said bores to be alined with tllB'fiXBCl bore 13 in providing'a continuous passage thercthrough. Pairs of suitable lateral flanges 17 are provided for the valve casing as indicated in Figs. 2 and 3 in order that such casing may be firmly secured in the offset portion 11 by means of suitable fastening means 18 rigidly connecting the said flanges to the bottom 19 of the fuel tanks 10 in which the oil-set portion 11. is formed.

Hollow bosses 20 are formed on the lower side of the valve casing 12 in a. corrcspond- I 23 and surrounding said reduced extensions.

Valve stems 24 are provided for each of the valves 15 and are adapted to extend upwardlyand protrude through a plate 25 ex- 26 which latter are recessed to receive plugs 27, the bottoms of which. are recessed oppositelyto the enlargement-26 in order to provide stuifing glands 28 to prevent the escape of the fuel by evaporation.

The exterior ends of the valve stems 24 are adapted to receive a turning member 29 whereby the'stem and the valve of each, stem may berotated to producethe proper regulation of the bores 16 in conjunction with the casing bore 13. 'Positioned adjacently to the turning members 20 are adjustable pointers 30 formed of a collar portion and a lateral enlargement projecting from the collar. portion, an adjusting screw 31 being received ina suitable aperture to the collar portion in orderto bear upon the valve stem 24 and maintain the pointer 30 in its adjusted position. a

Forcooperation with-the pointers 30 there is provided a dial such asillustrated indetail'in Fig. 5 anddesignated in the form illustrated in Figs. 1., 2 and 3 by the numeral 32, such dial being formed on the enlarged upper surface of the plate and being concentrically. positioned as regards their respective valve stems. These dials are provided with any desired number of peripheral characters and are designed .to form a safeguard against the unauthorized placing of the valve bores 16 in alinement :with the valve casing bore 13 since the operator of theturning members 29 can only be assured that all ofthe valves are in the necessary alinement in which fuel is permitted to flow'through the-conducting fuel'pipe 33 by the position assumed by the pointers with respect to the dials 32, such pointers having been previously adjusted so that their position immediately over any particular character on the dials.

' 32 will be 'concident with the alinement of the valve bores 16 with the casing bore, as may be readily determined atthe time of installation of the device. a

lllustratedin Fig.4 there will be seen a device substantially similar to that Which has just been previously described with one main difference, which is that the valve ria sing 12 is not positioned. interiorly of the 3 fuel tank but is provided with offset ends 35 whereby it may be interposed between, spaced sections 36 of the fuel tank by means of the sleeve connections 37. In other respects the structure shown may be considered as substantially the equivalent ofthat previously disclosed but it possesses this great point of advantage over the first described structurein that itmaybe positioned at any point which" may be found desirable from the standpoint of convenience to (the. operator, providing only thatleads from the fuel pipe are connected respectively'ton tween the fuel tank and the motor must be established through the valve casing 121 The, offsetting of the ends 35 is particularly designed to prevent fraudulent atpermutation dials 3:2 and also enables the provision" of a straight bore16 through the valve plugs 15 instead of the V or'Z-shaped bores previously considered necessary in devices of this character and accordingly cheapening to a great, extent the cost of manufacture of the device. Hardened and exteriorly' threaded plugs 38 are provided as shown in the bosses 20 of the second form and are cut off flush in order to defeat any attempts to manipulate the extensions 21 of the valves. It will accordingly be seen that by means of the simple yet 'eflicient structure described in the foregoing that means have been, provided capable of attaining the previously set forth objects and that this invention may accordingly be claimed as presenting the advantages and desirabilities obviously inherent in the accomplishment of such objects- I i While in the foregoing however, there has thus been illustrated in the drawings and described in. the specification such combi nation and arrangement of elements as constitute the preferred embodiment of this invention, it is desired to emphasize the fact that such minor changesin the matters of proportion'and degree may bevmade in later adaptations of this device as shall not alter the spirit of the invention as defined in the appended claimsl What is claimed is: 1. The combination with a tank formed with a depression in the bottom thereof, of I Q means'for con'trollingthe discharge from f said tank includingqa casing positioned within said depression and leading from the tank, a. longitudinal bore in the casing, valves provided with. registering. bores to intersect the casing bore, a stem for each valve projecting through the upper portion f of the, tank,xand permutation -means associated with each individual valve stem.

2., The combination with a fuel tank having an offset portion formed in the bottom thereof, of a valved casing seated in said ofi'set portion, flanges formed on said valved casing, for securement to said tank, valves rotatably positioned within said casing, extensions for said valves, resilient'means cooperating with said extension to correctly seat said valves, stems for said valves, dials surrounding said stems, and means coacting with said dials and adjusta'bly I mounted upon saidstems to indicatethe position of each separate valve.
