GEORGE C. HURT, OF BLACKSTQNE, VIRGINIA.

Specification of Letters Patent.

. Patented May 11, 1920.

Application led Augiust 2'1, 1918. Serial No. 250,843.

To all whom it may concern.'

Be it known that I, GEORGE C. HURT, a citizen of the United States, residing at Blackstone, in the county of Nottoway and E'. of Virginia, have invented new and useful Improvements in Combined Caps and Funnels for Radiator-Filling Tubes, of which the following is a specification.

This invention relates to a combined cap and funnel for the filling tube or neck of an automobile radiator which is so constructed that when applied to said tube 1n one position it Will serve as a convenient means for directing Water `into the tube and when' applied in another or reversed -position to-said tube it Willoperate as a cap therefor in order to exclude forelgn matter therefrom.

It is the object of this invention to provide a combined cap and funnel for` this purpose which is ,simple and inexpenslve 1n construction and efficient in operatlon and which can be readily applied to Athe filling tube for performing either of the above described functions.

In the accompanying drawings: r

Figure l is a vertical section showing my.

combined cap and funnel applied to the filling tube of a radiator 1n such manner that the same will serve as a cap therefor.

Fig. 2 is a similar View showing the same applied to the filling tube in such position that it serves as a Water funnel for the same. Fig. 3 is a plan View of a combined cap and funnel embodying my invention.

Similar characters of reference indicate corresponding parts throughout the several views.

l represents the upright filling tube or neck of a radiator such as are commonly employed on automobiles for cooling the water circulated around the heated parts of the gas engine which drives vthe automobile. In the particular form of this filling tube shown-in vthe drawings, the same is provided in the upper end of its bore' with an internal sc reW thread 2 'and atthe lower end of this thread with an upwardlyffacing annular shoulder 3, although my invention is applicable to other forms of filling tubes. lVitliin this filling tube is arranged the upper portion of an overfiow or vent pipe 4 through which any excess Water which may be poured into the radiator as well as any steam or vapors which may be genverated in the radiator are permitted to iow particularly for cooperation with this construction of filling tube and the arrangement of the over-flow pipe therein, is constructed as follows:

' 5 represents an inner annular Wall preferably. of cylindrical or tubular form Which is provided on its periphery adjacent to one end thereof With an external screw thread 6 which is adapted to engage with the internal screw thread of the filling tube. At its threadedend this inner wall is closed by a head or diaphragm 7 which latter, in the form shown in Figs. l and 2, is preferably dished inwardly so that upon screwing this inner Wall into the filling tube until the respective end of the same engages with the shoulder 3 of the tube, said head will be spaced from the upper end of the overfioW pipe and thereby permit the free escape of. Water as Well as steam or vapor from the upper part of said filling tube outwardlyv through the overflow pipe. Adjacent to that end of the inner wall opposite to that which is closed by the head 7, this Wall is provided With a water inlet which is preferably constructed in the form of a plurality of openings 8 which are arranged in an annular row around this inner wall and in such position that when this device is applied to the filling tube to serve as a cap, t e space within the inner wall will be cut off .rom communication -with the interior of the filling tube and thus exclude the entrance of any foreign matter into the radiator.

9 represents an outer annular wall which is preferably constructed of conical or tapering form and arranged around the inner Wall. This outer wall is preferably of such length that its large end extends a considerable distance beyond that end of lthe inner- Wall which is -closed by the liead'7, and the opposite end of this inner Wall is connected with the corresponding small end of the outer Wall in such manner that a seat is formed for engaginfr the upper end of the -f iii ln the preferred construction, the small end ci the outer wall is connected with the corresponding end oi the inner wall by a conical web l() which tapers inwardly and in a direction opposite to the taper oi` the outer wall. and the outer iai-e of this web is provided with an annular packing: ring ll oi rubber or siinilai" elastic inaterial which is oi' corresponding tai'iering forni and constitutes an elastic seat which, upon eiigiag ing with the upper end of the tilling tube, as shown iu Fig. 2, fornis a tight `ioint therewith, so that upon pouring water into the larigji` end of the outer all in this position ofthe parts,tliis water will be :oiiducted through the openings iii the inner wall to the interior of the fillinegr tube without liability of any o'l' this water leaking past the joint between the web and the tube and spilling: onto the adjacent external parts o'f the radialor.l lt is therefore possible to always keep the radiator in a clean condition iiistead of incurring the liability of spotting:

lthe radiator. lWhen this device is employed as a cap t'or the radiator tube, the outer wall flares downwardly around the filling` tiibe and produces ,a neat and iinished appearance of the same.

By combining the cap and filling funnel in this manner, it is unnecessary to employ,

separate devices ior this purpose as is commonly the case and it also positively prevents loss of the Jfunnel as frequently occurs when the same is iii-ade separate from the cap, so that means for properly fillingr the radiator with water are always a failable.

ln the preferred ronstructionof this device, the inner and outer walls, the head and the web are niade troni a single sheet of metal by siiinniugi', stamping or otherwise, but if desired 'these parts may be constructed in any other suitable manner.
