C. L. LEHMAN ET AL AUTOMOBILE RADIATOR mm March 14. 1 22 .2 Sheets-Sheet 1 Patented Mar. 24, 1925.

UNITED STATES CHARLES LEWISLEHMAN AND JOHN GEORGE CONNELL, OF CORONADO, ALBERTA PATENT OFFICE.

CANADA; SAID CONNELL ASSIGNO' R OF ONE-HALF OF THE ENTIRE RIGHT TO HENRY CON'BAD VAKINER, OF EDMONTON, ALBERTA, CANADA.

AUTOMOBILE RADIATOR.

Application filed March 14, 1922. Serial No. 543,798.

To all whom it may concern:

Be it known that we, 7 CHARLES Lnwis LEHMAN and JOHN GEoRoE GONNELL, citizens of the Dominion of Canada, of the town of Coronado, in the Province of Alberta, Canada, have invented new and useful Improvements in Automobile Radiators for the Cooling of Water, and which the following is a specification.

The invention relatesto radiators for internal combustion engines and the principal object thereof is to produce a radiator of which the parts may be easily removed by an unskilled workman for the purposes of repair and renewal.

With this object in view the invention consists in the construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, in which:

Figure 1 is a pers ective View of the invention, a portion 0 the fins being shown cut away.

Figure 2 is a similar view of the radiator and fins but with the latter removed.

Figures 3 and 4 are detail perspective views of the top and bottom tanks respectively of the radiator.

Figures 5, 6, 7 and 8 are detail perspective views of a tube, atop strip, a bottom strip and a tube section respectively.

Essentially the invention comprises the lower and upper tanks A and B of which the former is provided with a centrally disposed water inlet D and the latter with a similarly shaped outlet D. In the top face of the lower tank and bottom face of the upper tank there are formed the rectangular openings G for the reception respectively of the perforate plates or strips G and G the latter carrying the nipples Gr in registration with the perforations. The nipples G are interiorly threaded for the reception of the extremities of the circulating tubes or pipes G which at their remote ends are provided with the running threads G for the reception of nuts B the lower ends of the tubes threadingly engaging the perforations in the plates or strips G and a water tight connection being effected by securing the nuts B thereafter into firm engagement with the upper faces of the plates or strips'G The plates or strips G and G are secured in place in openings G by brazing or soldering.

In order that the tubes may be adequately protected, a series of parallel fins C is provided, slotted as indicated at C so that they may be arranged transversely of the pipes or tubes G with their front edges in the plane of the front faces of the upper and lower tanks, the slots providing clearance spaces for the tubes. The fins at their ends are secured, as by soldering or brazing, with the upright plates or strips C which, when the fins are disposed in proper position, shield the two outer series of pipes or tubes G The fin section is secured in place by 2 bolts D soldered or otherwise secured tothe top and bottom faces respectively of the uppermost and lowermost fin and their threaded extremities pass through the ears E formed on the upper and lower tanks, the threaded extremities of the Z bolts receiving nuts for securing the fin structure as a whole in place.

When it is desired to replace any one of the tubes, the fin structure is removed by detaching the nuts secured to the Z bolts D, when the fin structure may be withdrawn from the radiator and the defective tube removed after loosening its lock nut B The invention having been described, what is claimed as new and useful is:

1. In a radiator, an upper tank, a lower tank, said upper tank having inset in the under face metal strips provided with depending internally threaded nipples, said lower tank on the upper side having perforated metal strips inset therein and being provided with threaded perforations, tubes having external threads at their opposite ends and engaged at one end in said nipples and at the other end in the strips in the lower tank, said lower threaded ends being provided with lock nuts for abutting engagement with the strips in the lower tank.

2. In a radiator according to claim 1, a being provided with perforated ears and fin structure having slots into which the said fin structure being provided with Z tubes fit. bolts having threaded extremities passing 1 3. A radiator comprising upper and lower through said ears for the reception of re- 5 tanks, circulating tubes connecting said taining nuts.
