RADIATOR.

Application filed September 8, 1925. Serial No. 55,104.

The invention relates to radiators and more especially to an improved radiator construction involving particularly the connection between the filler neck and radiator shell or casing. According to this invention a floating connection between the filler neck and radiator shell is provided, together with means for adjusting the connection, to compensate for differences in size in the radiator parts and to compensate further for wear, whereby objectionable rattling is eliminated, and a proper union between the parts constantly assured.

The invention has also among its objects to simplify, render more efficient, and improve generally devices of this general character, and these as well as other objects, advantages, and novel details of construction7 will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings wherein Figure 1 is an elevation of a radiator constructed in accordance with my invention, certain parts being broken away to show interior construction, and

Figure 2 is a side elevation of the radiator shown partly in section.

Referring now particularly to the drawings wherein like reference characters indicate like parts, it'will be noted that there is illustrated a radiator core 10 which has formed therewith and as a part thereof, upper and lower headers or tanks 11 and 12. This core construction is arranged in a radiator casing 13 of the usual construction, surrounding the same in the customary manner.

The core may be secured within the casing in any suitable manner but the connection therebetween is herein shown as consisting ot bolts 14 passing upwardly through the bottom of casing 13 and threadedly engaging lugs 15 arranged within the bottom tank 12. The bolts 14 are preferably, although not necessarily, spaced equi-distant of the vertical center of the radiator and interposed between the bottom wall of tank 12 and the bottom of casing 13 is a strip of yieldable material 16. In this manner an anti-rattling connection is assured between the core and casing at this point and a slight relative movemnt between the core and casing is permitte A filler neck 17 projects upwardly from upper header 11 and Vextends through an opening 18 formed in casing 13. Fille-r neck 17 is provided, adjacent that portion which crit-ends through casing 13, with a ycircumferential shoulder 19. The greatest diameter of filler neck 17 is slightly smaller than the diameter of opening 18, whereby the filler neck is slightly spaced and loosely engages opening 18.

Arranged upon circumferential shoulder 19 of filler neck 17 is a circumferential yielding member 20 formed preferably of rubber or other similar material. This filler member 20 is designed to extend between ller neck 17 and the wall of aperture 18 and to center the filler neck with reference to the opening 18. A nut 21 in the form of a collar threadedly engages filler neck 17 and iS adapted to be screwed down against yieldable member 20 for the purpose of holding the same firmly against shoulder 19 and for compressing the same to expand it circumferentially and to cause it to irmly engage the wall of opening 18.

With a structure of this character it will be readily apparent that while a yieldable and floating connection is provided between the filler neck and the radiator casing, that any rattling at this point of connection may be positively prevented as the filler member 20 may be compressed more or less as the occasion demands by means of nut 21 to compensate for any wear of the parts or for any variance in size. W'ith the yieldable member 20 irmly engaging the filler neck and the wall of aperture 18 the filler neck will be centered with reference to the opening to prevent any met-al to metal contact andi a limited amount of relative movement between the core and the casing is permitted, which will tend to compensate Y for stresses imparted to the radiator.

While an embodiment of the invention has been illustrated and described in some detail it will be readily apparent that various changes andl modificati ons may be resorted to without departing from the spirit and scope of this invention, and to this end reservation is made to make such changes as may come within the purview of the accompanying claims.

Wvhat claim as my invention is:

1. In a radiator, a. casing, a core provided with a iller neck engaging an opening formed in said casing, anexpansible member carried by said filler neck and disposed radially between said filler neck and casing and means adjustable on said filler neck for expanding said member radially.

2. In a radiator, a casing provided with an opening, a core formed with a filler neck having a floating connection with said opening, a yieldable centering member interposed between said liller neck and casing, and means on said neck for clamping said yieldable member to radially expand the same.

. 3. Ina radiator, a casing provided with an opening, a core formed with a iiller neck engaging said opening, a yieldable centering member interposed between said filler neck and casing, and a nut threaded on said filler neck and engaging saidyieldable member for expanding the same.

4. In a radiator, a casingprovided with an opening, a core formed With a iiller neck engaging saidopening, a circumferential shoulder formed on said iillerneck, a yieldable member engaging said shoulder, and a clamping nut threaded on said iiller neck for coinpressing said yieldable member, for the purpose set forth.

` 5. A radiator comprising a casing, an element Within theI casing provided-y with a iller neck extending Within an opening in the casing and spaced from the innerwall of said opening, a yieldable member forming a connection between the iiller neck and casing to absorb relative vibrations therebetw en, said iiller neck being provided with a shoulder forminga support for the said yieldable member, and means act-ing on said; yielding member for distorting the samelaterally between the said shoulder and said means.

In testimony whereof aiix mv signature.
