Application filed January 8, 1914. Serial No. 811,108.

T0 all whom it may concern:

Be it known that l, lVILLiAaI Q. PFAHLER, a citizen. of the United States, residing at Toledo. in the county of Lucas and State of Ghio, have invented a new and useful Tank-Gutlet, of whichthe following is a specification; v

This. invention relates plugs for tank outlets.

An object of the present invention is to provide an outlet device or plugv which will allow the tank to be readily drained and at the same time will prevent foreign material from entering the outlet pipe.

A further object is to provide an outlet device with a storage chamber for the deposit of the sediment and foreign material which may be present in the liquid contents of the tank and thus it will bev prevented from entering the outletl pipe. x

A further object isto-provide a device of the aboveV mentioned type which may be readily removed from the tankv for the purpose of cleaning and to ascertainthe conditionthereof. f f I,

'lith the foregoing and other objects in view `which willf appearfas the description proceeds, the inventionfresides in lthevcom-l bination and arrangement. of-fparts andxin thedetails of eonstructin hereinafter described `and claimed, Ait being understood that changes in the preciseembodiment of the invention herein disclosed; can. be made to improvements in within the scope of what is claimed, with--v out departing: from thespritpf'.theirv ventio i" u f In the drawings accompanying thisspecification and forming a; part thereof, the preferred embodiment of f my invention is illustrated, in which y Figure 1 is a view in elevation of my device taken through the longitudinal vaxis thereof and illustrating a portion ofthetank to which it is secured. Fig. 2 is a sectional view taken on'the line 2-2 of Fig. 1.

Referring now to the drawings in which similar reference numerals designate analogous elements .throughouf the several Hgures, 3 represents the side wall of a tank and 4 the bottom. The bottom 4 of the tank is provided with the outlet opening 5 rivets Gr'orother-equivalent means, is the plug attaching member-7 which includes the .the said plug attaching member is rigidly secured to the tank and effects a' liquidtight juncture therewith. i

T he plug 10 which is detachably secured to the plug attaching member 8 includes@ centralv pipe-like body portion 11 whichis threaded at its lower` extremity as at 12 and to which lower extremity maybe secured a pipe for the conducting of the liquid which flows from the tank toany'desired point. It is to be noted that the device herein disclosed is particularly fadapted for use with gasolene tanks in which a pipe-like body portion 11 will-communicate with the carbureter and thus it is of prime importance to prevent any foreign lmaterial from entering the pipe-like body portion `as the same would eventually find its way to' and llodgein the needle valve of the carbureter proper and efficient working the concentric upst'anding flan-ges 14 and 15. 'The outermost flange l5 is externally thread-` ed and is spaced' a slight-distance from the extreme edge of the diskso as to threadedly engage the sleeve 8 and with the periph- .lill .edge thereof lying flush with the outer surface of the sleeve, The outer flange 15 is -1 of relatively less height than the inner flange 14 so that shouldfor any reason sediment i collect upon the top edge of the flange .15 it will not be liable to gravitate into the annular opening between the flange 14 and thel body portion 11. Rigidly secured to the outer surface of the liange or sleeve 14 is the'fwire screen 16 which is dome-shaped as at 18 at its upper extremity and which is of suliciently fine mesh to practically exclude all foreign material of such dimensions as l would interfere with the proper working of the valves of a carbureter. The wire screen 16 is cylindrical in outline as illustrated in Fig. 2 and completely incloses and protects the opening 19 which extends through the pipe-like body portion 1 1. The

'space intermediate the fianges'ory sleeves 14 and 15 forms an outlying collecting receptacle 2O in which the foreign material will collect which is of too large dimensions to pass through the screen 16. The space between and defined by the opstanding liange 14 and the body portion 11 forms a recepta'cle 21 in which is adapted to collect any line particles which may pass through the screen 16. However, the collection of material within thereceptacle 21is .a remote l contingency as the screen is made sufficiently fine' to exclude all articles' from passing therethrough. In order that the material collected within the outlying and annular compartment QOVmay bedrained therefrom without requiring the removal of the entire plug,'a,pet cock` 22 is provided communicating with the bottom of the receptacle and which may be opened either for the purpose of' draining the'sediment which ymay have 4become deposited within the said receptacle or for the draining of the entire contents of the tank as may be desired. A The body portion l1 4 which includes the outlet central opening l19 is of suiiicient length so as to extend above the bottom 4 of the tank so as to--further preventV the passing of foreign material through the `screen which .might happen by the force ofthe current were the said* body portion to terminate below the bottom 4 of the tank. The disk 13 is providedfwith the enlarged portion 23 which presents a wrench engageable surface and.

curing thefsame to and extending below the side walls ofa tank opening, a plug detachably secured to the said sleeve and including a centrally extending pipe-like body portion,

an outstanding disk carried by said bo'dy portion intermediate its ends, the said disk provided with two concentric upstanding sleeves, the outermost sleeve being detachably secured to the said plugattaching and supporting member sleeve, the said pipe body .portion extending above the plug attaching member when secured thereto, the lannular space between the said upstanding sleeves of the disk forming a dirt collecting receptacle, a cylindrical screen carried by and affixed to the innermost disk sleeve and extending above and encompassing the said pipe body portion, and means communicating with the said dirt receiving receptacle adapted to drain the same.

2. A device of vthe class described comprising a sleeve, means for securing the same to the bottom of a tank, a pipe provided with a disk intermediate its ends, the said disk engaging the said sleeve with the pipe extending above the bottom wall of the tank,l

said disk provided with a concentric upstanding flange, a wire screen carried by said iange spaced from the upstanding portion of the pipe andv housing the same therein, the annular space between the screen and the said sleeve forming a dirt collecting receptacle, the annular space intermediate the pipe and the said annular flange defining a second foreign material collecting receptacle. j

In testimony that I.claim the foregoing as my own, I have hereto aixed my signature in the ,presence of two witnesses.
