This invention relates to mp rovements in racliator caps, or apparatus oarecl thereb The prmary object t-hs nventon s the provson of an mproved emblem or devee adaptecl to be part of a racliator cap for pos1- ti0ning over the top water nlet openngs of automobile ra'diators, ancl whch has inuprovecl means thereon to permt the efficent cleterminaton of the thermal eflicency of the water wthnthe radiator.

A further object of ths iuvention s the provsion of an mproved raclator cap, whch includes an ornanent or emblem whch may be characcerstio of the emblema adoptel by the manufacturer of the car upon whch the cap s to be used; the emblem havugeharacterst-c means thereon whchmaybe com m0n to any number of d1flerent emblems, to

display the slogan or name of the car or manufacturer 01' the car at the front thereof; che improvecl cap havng means assooiatecl in a novel relation therewth to illuminate a compartment wheren the rays of lght throw the slogan or nameinto relef; the improvecl dev-ice havng a thermometer assooiafied therewth in aneficient and llumiriated relatoi1 or.determnng th e temperature ofthe water in the -rac liator i1pon whch the cap is positioned. 7 Other objects and aclvantages of ths 111- vention Will be apparent-cluring che oourse of the ollowng cletaled descrption.

In the accompanyng clmwing, orm1ng a, pat of th s specifictin, andwheren similar reference oharacters designate corresponclmg pats throughout the several vews,

Figure 1 is a, front el-evaton of the 1111- proved clevce aclaptel to be detachably connek:ted upon a radiator cap, 01 rigclly attachecl as a part of the cap.

Figure 2 is a rear View of the clevce of Figure 1, showng parte in seot-on.

Figure, 3 is a cross sectional view taken through the mproved radator cap structure, substantally on che lime 8-8 of Figure 1.

In the dretwng, wheren for the pur'pose of ilhistraton s shoWn Only apreferred embdiment of the nvention, the letter A may geuerally designate che part of che radiator u1ay be slpped through a sutable opening cap in whch ths nventon lies, whchmay include a base 10 having a bott0m plane surface 11. Centrally from the base 10 clepends a hollow screw threaclecl ,sha,nk 12 whioh m an ordinmycap base (not shown); nut meaus 141 beng 'acljustable tbereon to c1amp beneath the top Wall oi the cap toattach the apparatus A upon the cap base, in a manner Whoh s well uuclerstood. i

In the preferred arrangement the base 10 may have ntegrally cast orotherwse connectecl therewth-spaced wings 17 and 18, which arcuate upwarclly in spaeed relaton end tl1en inwarclly ai; their apces 19, toprovide a sori: ofopenng or area 20 wherenit s clesrecl to oonneet certain parte ofthe inveuton to be more fully described. The wngs 17 and 18 are formed as a, body wheh bus a, comPartment 21 theren mmecliately above the base 19; the eompartment- 21 extenclng upwardly along the wngs 17 and 18. This oompartment is open at the rear of the Wings, end a detachable cover plate 22, Shapecl to conform wth che outline of the wugs 17 ancl 18, above che base 10, s provdecl, end adaptedto be detachably conneced to che margiusof thewngsl7 and 18 by Screws2l, to close the cor1partment 21.

In axial algn'ment With the shztnk'l2, the se fcasting s pro.vdecbwth Va sort offrustocoriical sha'nk 25, -extehclug upwafdly into the space between the Wn'gs 17 and 18, and up0n which is.ntegrally ofotherwsle connected laterallyfextendng urns 27 and 28, whieh .respectively extend towmrds the wings ,17 'aud 18, and may be coriueeted therewith, f clesre'dQ A compartment 30 s providecl in che upper part of the shank 25, Whch extencls into thearncis27 ancl 28, butwhch s seprzxted from the compartment 21 except by me2ins of ani openng tl1ro-ugh Which a themometer stem 31 extends; ths stem 31beng st1itably conneoteclon the base 10, aricl at its lo'wer end extenclng into the hollow screw threcled shank 12, and thenc upWzirolly through the eompaftment 21 and vertcally 'nto the o;ompartmenii 30, as shown in Figure 2, terminatng short of the top wall 35 above the compartment 30. This thermoneter stem receive e1ectric Iight bulbs 60, by means ofa margnal strip 0f metal 4l, which s held,

in place by screws 42. This plate 40may be clamped against a flexible gasket if desred.

A Verteal strip 44 of the glass plate- 40 is transparent, mmedately, t 0 themear of: the upper end of the the'rmometer stem 31, thru Whiehthe thermometer stem s y-isible from thedriyers -seat ofthe velcle, 130 determhe thetemperatu're of;the water in the radiator uponwhiehfihecap -s positioned. Otherwse the-rear sur-aeeof t'he plate 40 s opaque at 44 The front Wa1l of this 'casiug, shown at 4'jin Fg'ures 1 and 3 ofthe drawing, may be sr1itably pr0Vdedwthstencil-lke openngs 48, intheferrriofltters or other, indeia pertnent to the car or other article or 1riatter Whch the capis-adapted 150 represent or advertise; Inthi's front wa1l 47 is also provided a-n openng50 between-the arms 27 and 28; mnedately 'at the front of the upper por'tion ofthe thermor'n'eter stem 31, as a means of admttng aelejar vsion of the tremometer-stem, duringdaylight travel, and to aford a viewf Of th'ethermometer stem from the front of thevehcle. V

Theend wa11s 55 and56 of the arms27 and 28are provided with sockets 58 adapted to wh'ch no-illuminate the cdmpartment 30 ai; both sdes ofthe thermometerstem 31, so that itmay be readly vsible thru che openings 44 and 50. The wires 6lfrom the bulb sockets 58:ex tendjtransversely thru openings in the casngwalls of the emblem wings 1and 18, and extend downwardly through the come partment-2l, passng through an opening 68 m the base 10, leadng to any sutable location, prefe*ably and insertng plug 65, as shownin Figure 2. e

It s apparent -fromfl1e foregoing that a novelradiator cap has been provded, emb odying important structural features whch Will permt th ecap to dsplay an emblem or other insignia in such manner thatan illuminfaed eompartment may display advertising or otherydata to the fro nt of the veh'cle, and and illuminate a Water temperature indicator so that the. driver of the vehcle may readly observe the same.

Varous changes in the shape,sze, and arrangement O'f parts may be made to the form, of invention heren shown anc1 described, without departng fromthe spirit of the invention or the scope of the claims.
