To all whom t may/concern.'

Be it known that I, JOHN M. FEDDERS, a citizen of the United States, residing in the county ofl Erie and State of New York, have invent-edl new and useful Improvements in Radiators for Automob iles, of which .the following is a specification.

In radiators for automobiles and the like as heretofore constructed a considerable amount of water was liable to be lost through the vent or automobile tossed is a fragmentary vertical section of the upautomobile radiator provided per part of an .Fig 2 is a, horiw1th my improvements.

zontal section taken in line 2.-2, Fig.' l.

Fig. 3 is a detached side elevation for the guard of the filling tube. Fig. 4 is a perspective view of the guard for the vent and overflow pipe. l

Similar characters of reference indicate corresponding parts throughout the several views. V My improvements are applicable to various forms of radiators for automobiles and the like, thatvshown in the example, comprising an upper Water header or box 1, a filling tube 2 projecting upwardly -from the top of this headerand communi-- cating at its lower end with the interior of the same, a cover 3 for the upper end of the flling'tube which is detachably connectled with the latter by means of an annular depending flange 4 forming part of the cover and having an external screw thread which engages with an internal screw thread 1 end of the filling tube, and ain the upper vent or overflow pipe 5 having its upper or inlet end arranged vertically within the fillat W 'ters the upper end overflow pipe as the about in passing overV vrough roads and caused the water jto splash drawings for ing tubev on one side thereof while its lower end extends to the exterior of the-radiator.

time to time by `removing the coverv and pouring the water through the filling tube 1 mto the upper header. Any surpluswaterenof the' overflow pipe 5 and escapes at the lower end thereof to the eX-.

ter1or of theradiator and any. steam which is generated within the radiator by the heat from the engine also escapes to the exterior through this pipe -which at this time serves as a vent for this purpose.

For the purpose of while being agitated in the radiator during the passage of the automobile over rough preventing the water l' ater may be added to the radiatorV from roads'from splashing upwardly into thel fillmgtube a guard device is provided for the same which preferably comprises an imperforate body 6 of substantiallyy tubular form arranged vertically within the filling tube and provided on one side with a longitudinal external groove 7 which receives the upper portion o the vent and overflow pip t its upper endv this imperforate tubular body. is provided with a laterally projecting supporting flange 8 which is normally clamped between At its lower end the body 6 1s provided with a screen 11 extendlng horizontally across the same which screen is preferably constructed of woven wire although th structed in any other suitable manner.

As th agita-ted perforate. tu vular body of for the filling tube and -is therefore prevented from splashing into the upper part. of this tube whilev at the same time free communication is maintained in the upper partthe interior 'of lthe of the filling tube and header through the vmediumof' the screen 11 which' latter permits water to be'poured from the filling tube into the handle and also permits the Water to rise and fall normally within the body of thefilling tube guard.

VIn order to prevent any Water from splashing into the upper end of the vent and overflowl pipe and thus become wast-ed a the upper endv the guard device iaimvea guard device for this pipe is provided which 'wardly facing internal shoulder, a cover for is preferably constructed in the form of a closing said filling tube having a depending cap 12 which fits over the upper end of the flange which vis connected by a screw joint vent and overdow pipe and forms therewith with the inner side of said tube and has its passages 13 which place the interior of the lower end facing said shoulder, a vent and water header in communication with the overflow pipe arranged within said tube on vent and overflow pipe. rllhese passages are one side thereof, and a guard for said tube preferably formed by providing the cylincomprising an imperforate tubular body ardrical body of the vent and overflow guard ranged upright within said tube and prowith longitudinal beads 141 which are bent invided on one side with an external longitudiwardly and engage with the exterior of the nal groove which receives said pipe, alatervent and overflow pipe, and traverse beads ally projecting flange at the upper end' of which are bent downwardly in the top said body which is clamped between said of this last mentioned guard and engage shoulder and the cover and which is pro- 15 with the upper end of the vent and overflow vided with an opening for the passage of pipe, as shown in Figs. 1 and 2. rlhis vent said pipe and a screen arranged across the and overflow guard is held in place fric lower end of said body.
