To all whom it may concern:

Be it known thatll, EDWARD H. ELLIsON, a citizen of the United States, residing at Jamestown, in the county of Chautauqua andState of New York, have invented certain new and useful Improvements in Radiators or Coolers, of which the following is a specification. I

The invention relates to new and useful improvements in radiators for automobiles and more particularly to the construction of the conduitsthereof.

An object of the invention is to provide a radiator wherein the side plates forming the conduits are all similarly bent and shaped and are so constructed as to have an extended surface contact at the point of attachment between the adjacent conduits.

A. further object of the invention is to provide a radiator of the above character wherein the side edges of the plates forming the conduits are brought into contact throughout their entire length, thus reducing to a minimum the amount of solder necessary for connecting the same.

A still further object of the invention is to provide a radiator of the above character wherein the side edges of the plates forming each conduit are in contact throughout with alternately'large and small bends, the angles of which are of the same magnitude and face in the same direction .so that the outer face of the larger bend in one conduit may nest in the smaller bend of an adjacent conduit and be secured thereto throughout the entire length of the smaller bend.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

In the drawings, Figure 1 is a front elevation of the radiator partly in section and partly broken away, the sectional p'artbeing taken on the line 1"1 of Fig. 2. Fig. 2 is a sectional elevation taken transversely through the radiator, the end water course of the section being shown-in full lines andthe water tanks at the top and bottom being shown in section. Fig. 3 is a detail perspective view of three consecutive plates that are used to form the water courses, the one at'the leftand the middle one being joined together atflthe edges to form a complete water course and the one at the right formlng one side of the next water course. Fig. 4 is a section taken through, four plates on the line indicated by 4*4* of Fig. 3, show- ;ing two completed water courses spaced apart, the intermediate part of the water course, where the section is taken, being shown in full lines, while the edge of the water course, where the sidesare shown together, being shown in dotted lines. Fig. 5 is a sectional elevation of the water courses, showing a modification of what is shown in Fig. 4, a single division or partition plate being used between two consecutive Water .courses. F1g. 6 is an enlarged view of the joints between the consecutive water courses and the water tank at the top on the section line 6"6" of Fig. 2. Fig. 7 is a modified form of thewater courses.

My improved radiator 1 consists of a'water chamber 2 located at the top of the radiator and a water chamber 3 located at the bottom thereof. Between these chambers there are a plurality of conduits 4 and my invention is directed to the constructionof these conduits. Each of the conduits is made up of two plates 5 and 6 which are formed from a sheet of thin metal, preferably of brass or copper. The edges of these plates are drawn and shaped to ofiset. them from the intermediate part so that the plates between the side edges will be spaced to form a passage 10, through which the water passes from the chamber at one end of the conduit to the chamber at the other end thereof. These side plates are preferably bent so as to form substantially vertical portions 5 and inclined portions 6 located between the vertical portions. These inclined portions extend at an acute angle to the vertical line so that the passage 10 formed by the side plates is not only a continuous passage but it is free from all horiother a relatively small amount of solder is necessary for joining the same. These side edges are also shaped so as to form large bends 10 and small bends 10". These relatively large and small bends are arranged alternately and the metal, of course, forming the bends is connected, one bend leading into the next. The angles of the bends are of the same magnitude and face in the same direction, as will be clear from an inspection of the drawings.

While I have referred to the plates 5 and 6 as similarly shaped it will be understood that this term is used in the sense that certain sections of the plates are exact duplicates of 'each other, that is the side edges,

while the intermediate sections have the same general shape. The side edges must be offset relative to the'intermediate parts so that when a set of plates is brought to-\ gether to make a conduit they will be offset to form a passage therebetween for the water course. This is accomplished by having the offset in one plate opposite to that of the other plate. After the side plates, forming the conduits are brought together, then another conduit is formed and the large bends are nested'in the smaller bends of the adjacent conduit. That is to say, the outer face of the large bend at the vertex of the angle is nested in the small bend and this outer face makes contact with the inner wall of the smaller bend throughout the entire extent of the smaller bend. A

Figs. 1 and 2 of the drawings clearly show the larger bends nested in the smaller bends as described above.

vVhen solder is applied to the edges, the relatively large surface between adjacent conduits will be joined by the solder, the solder extending along the contacting edges of the entire small bend. This makes a very strong connection between the adjacent conduits and greatly increases the strength of the radiator.

From Figs. 4 and 6 of the drawings it will be apparent that the vertex of the angle of the large bend projects beyond the vertical wall 5 in the plate forming the conduit and this projecting of the larger bend beyond this vertical wall is particularly for the purpose of spacing. vertical walls '5 of adjacent conduits, thus forming not only horizontal air passages 11 bqt also vertical angular portions 6* ofthe conduit, while in Fig. 6 I have shown these edges ascoinciding with the medial line between these portions. This is immaterial as theedges may be arranged in either of the ways shown. 4

In Fig. 5 of the drawings I have shown a slightly modified form-of construction of radiator. The water conduits are indicated at 15 and 16 and these are formed vfrom plates shaped as described above. Between adjacent water conduitsthere is a separating plate indicated at 17, which is in the form of either of the side plates forming the conduit as the side edges of these plates are the same.

In rolling the brass or copper to the very thin gage required, pin holes and other similar imperfections frequently occur. If. these exist to such an extent that they cannot be From the above it will be apparent that I have provided'a radiator for automobiles or the like wherein the conduits are formed from lates which are similarly shaped throughout the length of the conduit. Furthermore, these plates are so formed that the side edges which are joined to form the conduits'are in contact throughout the entire length, thus reducing. to a minimum the amount of solder necessary for joining said edges Furthermore,'these side edges are so shaped as to form large and small bends, which small bends receive a portion of the larger bends of adjacent conduits, thus greatly facilitating the assembling of the parts and holding the adjacent conduits in the proper position for soldering until they have been dipped. Furthermore, this nesting of the larger bendin the smaller bend greatly strengthens the radiator as it provides a large contacting surface between the adjacent conduits.

The manner of connectingthe side plates of the conduits at the upper and lower edges thereof to each other and to the water chamber is of the well known construction and description thereof is not thought necessary.

It is obvious that minor changes in the details of constructionmay be made without departing from the spirit of the invention as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Let-. ters Patent, is

1. A radiatorfor automobiles including I in combination a plurality of conduits, each conduit being composed of similarly shaped platesbent so as to form therebetween a continuous passage, the side edges of said plates being bent so as to have contact throughout the entire length of the conduit and so as 1 ,eoaeva to space the plates to form said passage, said side edges having formed therein alternately relatively large and small bends the angles of which are the same and face in the same direction whereby the outer face of the larger bend in one plate may nest in and be firmly secured in the smaller bend of an adjacent plate.

2. A radiator for automobiles including in combination a plurality of conduits, each being composed of similarly shaped plates bent so as to form therebetween a continuous passage having vertical portions and inclined portions connecting said vertical portions, the side edges of said plates being bent so as to have contact throughout the entire length of the conduit and so as to space the plates to form said passage, said side edges having formed therein alternately relatively large and small bends, the angles of which are the same and face in the same direction, said larger bend projecting beyond the vertical Wall of the conduit to such an extent that when nested in the smaller bend of the adjacent conduit the Walls of said adjacent conduit will be spaced to form vertical air passages.

3. A radiator for automobiles including a plurality of conduits, each being composed of similarly shaped plates bent so as to form therebetween a continuous passage, the side edges of said plates being bent so as to have contact throughout the entirelength of the conduit and so as to space the plates to form said passage, said side edges having therein alternately relatively large and small bends the angles of which are the same and face in the same direction, saidconduits being arranged side by side with the large bends in the side edges of the plates forming one conduit nested in the small bend in the side edges of the plates forming the adjacent conduit and secured thereto throughout the entire length ofsaid small bend.

In testimony whereof I affix my signature.
