AUTOMOBILE-RADIATOR.

Specification of Letters Patent.

Patented May 25, 1920.

Apmicanon filed April 9, 1919. serial No. 298,737.

duty radiators, andthe principal object of' the invention is to construct a radiator which will not have any soldered joints, thereby dispensing with the many diliculties Vcustomarily experienced through breakageand the difficulties which such common `construction gives when making repairs.

A further object of the invention is to construct the radiator from interchangeable parts, whereby 'the samey can be readily. as-

sembled and '-repairs easily made and in such construction to utilize radiator-tubes connected to the top andbottom-tank by a special non-leak joint which not only permits of the ready insertion of the tube but also of the removal of the same.

A still further object is to construct the radiator in what might be termed tube sections to permit of the .removal of a tube section without interfering with the remainder of the radiator.

Wththe above general objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had -to the accompanying drawing in which Figure 1 representsa front View of the radiator.

Fig. 2 represents a vertical sectional vlew through the radiator at X--X Figui.`

Fig. 3 represents an enlarged detalled vertical sectional view through a portion of the radiator. i

Fig. 4 represents a horizontal sectionalkv radiator side supports 4 and 5. 6 represents the customary inlet pipe to the bottom tank and 7 the outlet pipe from the vtop tank, it being here understood that the circulating Waters pass to the radiator through the pipe Gand out of the same through the pipe 7.

According to my invention I prefer. to

-ha've access to the interior of the tanks for a reason later disclosed and in the present instance I have shown these tanks as fitted with removable front plates 8 and 9, such plates being detachably fastened as by removable screws 10 to the tanks. It is here also to be understood that a Water-tight joint is made when the plates are finally screwed into position. The top and bottom tanks are connected by means of a plurality of similar tubular radiating tubes 11 which, owing to requirements, have to-present com-` paratively thin walls.. The tubes 'are all similarly connected or jointed to the tanks at the top and bottom ends and I refer to arrange them in sets, there being in he present case five tubes in a set, running `from the front to the back of the radiator. There can bel however as many sets of tubes as occasion may demand. Each set ofvtubes appear between similar top and bottom base plates 12 and 13, the base plates being rectangular (see Fig. 4) and of a length equal to gire depth of the radiator from front to bac Each base plate is litted `with a number V of spaced facial projections or bosses 14 and the said base plates are bored' out an.equal distance in from the rear side as indicated at 15 and interiorly screw. threaded, the holes so formed communicating with second openings 16 of smaller diameter passing through to the front.

The radiator tubes 11 of each set are ar ranged with their upper and lower ends passing through the openings 16 of the top and bottom base plates and into the open ings 15 and once inserted they are vheld securely in place gby applying exteriorly screw threaded jam sleeves 17 into theopeningsl 15 and screwing them up against insert.- ed packings 18 located around the ends of the tubes and at the inner'ends of thesleeves.

The above arrangement connects in the present instance the Ilive tubes of a set to the top yand bottom plates butin the assembling of the radiator the jam sleeves 17 serve the further purpose of -fastening th'e tube sections-'in place between thetanks and this is done by providing screw threaded openings indicated at 19 and 20 in the top plate 3 of the bottom tank and in the bottom plate 2v tanks are connected by the tubes which open to the tanks through the open centers of the jam screws.

With this arrangement it will-be apparent that it is a very easy matter for one to remove a damaged tube as he simply has to drain the radiator in the ordinary way and then remove the front plates to allow him to get at'the jam screws associated with the particular tube.` A screw driver will release the 4jam screws and once they are released the damaged tube can be -pulled out and a new one readily inserted.

lf desired Ya whole-section of tubes can be taken out without interfering with the remaining sections, this being done by removing the jam screws which fastenthat particular tube section to the. top and bottom plates 3 andl2 of the tanks `3 and -2.

While l have described in detail the joint made between the tube andthe base plate,

it' will be readily understood this could be :renate 'through the tanks into the base plates and 'receiving the ends of the tubes and having their innermost ends engaging the packing strips.

2. AIn a radiator, the combination with top l and bottom tanks, of removable plates allowing of entrance to the interior of the tanks,

a plurality of upper and lower pairs of base plates bearing against the under face of the top tank and the top face of the bottom tank, radiator tubes extending between the tanks and with their upper and lower ends extending into the base plates, packings coutained within the base plates and surrounding the ends of the tubes and jam sleeves screw-threaded through the tanksinto the base plates and receiving the ends of the tubes and having their innermost ends engaging the packing strips. v
