namaronl Application filed July 27',

This invention relates to certain new and useful improvements in radiators of the character employed in connection with water cooled internal combustion engines, heaters, condensers, coolers, etc., and has as an object the provision of a reinforcing and guard rod construction which is of simpler construction than those formerly employed and which lends itself more readily to production.

In manufacturing radiators of the guard bar type, in which a conventional flat head is provided on one end of the bar, mechanics in assembling frequently either impose an excessive strain on the rods injuring the radiator shell or else fail to place an even strain on the bolts which results in a generally unsatisfactory condition, and this invention has as a further object the provision of an improved construction whereby the application of excessive strain on the rods is prevented within a reasonable degree and in addition a cheaper and better structure provided.

Another object of this invention resides in the provision of a guard rod of the character described having a nut for drawing the rod taut-and having means for preventing the loosening of the nut by vibration.

And a still further object of this invention resides in the provision of an improved radiator construction wherein common stock rod or bar material may be employed in the construction of the guard rods with better results than with special rods having solid heads on one end.

'With the above and other objects in View which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the recise embodiment of the herein dis-. closed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a front View of a radiator construction employed in my invention;

Figure 2 is a side view thereof;

Figure 3 is an enlarged, detail view, with parts broken away and in section, of one of 1928. Serial No. 295,695.

the guardrods detachedfrom the radiator;

vmerals designate like parts throughout the several views, 5 designates a radiator core having its bottom and top closed by cast ends or tank members 6 and 7, respectively, the I adjacent ends of the tank members being connected by side channel members 8 securedthereto b cap screws or other means 9. The rear of t e radiator may be provided with a tan enclosin casing 10; although it forms no partof t is invention.

The forward faces of the members 6 and 7 have forwardly projected vertically aligned lugs 10 preferably cast integrallytherewith and apertured, as at 11, to receive vertical guard rods or bars 12 which serve to reinforce the radiator construction and protect the core 5 against damage by collision. The lugs 10 are preferably strengthened by vertica webs 13 to withstand the stresses imposed thereon b the guard rods. Heretofore, the guard re s or bars have been in the form-of elongated bolts having the conventional solid head structure, but this has proven objectionable in that they. afiiord no protection againstdrawing the nuts 13' on the upper ends thereof too tight and this feature is overcome by replaein itherordinary solid fiat heads of the rods by t e structure now about to be described. f

The lower end 14 of each bar 12 opposite its threaded end 15 is preferably bored a short distance, as at 16, and expanded, as at 17, by the insertion of a suitable expanding tool, not shown, the expanded portion form ing the head of the rod. With this construe.- tion, a degree of protection is afi'orded against placing too great a strain on the guard rods in tightening the nuts 13, as the tapered or flared heads 17 have a'degree of resiliency which also assures the placing of an even strain on the guard rods. In addi tion, the tendency of the rods to become loose and rattle due 'to the vibration of the engine with which the radiator is em loyed is overcome by a locking jam nut 18 t readed on the upper end. of each guard rod and drawn against the underside of the adjacent lug 10.

In addition to afi'ording protection against placing of excessive stress on the guard rods and consequently the radiator heads and the assuring of the placing an even strain on all the rods, the construction illustrated permits a more economical construction of the guard rodsas ordinary stock rod or bar may be employed, as will be readily apparent.

What Iclaim as my invention is:

1. In a radiator construction including end members having aligned apertured lugs and a guard rod passed through the apertures ofthe aligned lugs, a flared head on one end of the rod, and a nut threaded on the other end of the rod andplacing a strain thereon. 2. In a radiator construction including end members having aligned apertured lugs and a guard rod passed through the apertures of the aligned lugs, a tubular flared head on one end of the rod, and a nut threaded on the other end of the rod and placing a strain thereon, said head having a degree of resiliency to maintain the rod under tension.

3. In a radiator construction including a core member, top and bottom members for the core member, series of apertured lugs carried by the top and bottom members in vertical alignment respectively, guard rods for the core member having their ends passed through the apertures of aligned lugs, said guard rods each consisting of a rod boredat one end and externally threaded at the other end, an expanded flared head at the bored end of the rod to engage the adjacent member lug, and nuts threaded 0n the threaded ends of the rods to place a strain thereon; said flared heads having a degree of yieldability to protect the radiator against the placing of excessive stresses thereon in screwing up said nuts. I 1

4. In a radiator construction including end members having aligned apertured lugs and a guard rod passed through the apertures of the aligned lugs, a tubular flared head on one end of the rod, a nut threaded on the other end of the rod and engaging one side of one lug to place a strain on the rod and draw the flared head into the aperture of the other lug, and a lock nut threaded on the rod engaging the other side of the first mentioned lug to prevent displacement of the first nut by Vibration. i

' In testimony whereof I have hereunto affixed my signautre. FRED M. YOUNG.
