in the art to which it appertains to make and use the same.
The present invention relates to improvements in automobile radiators, and has for an. object to provide a coil construction disposed between two headers to avoid the complicated mesh structure as heretofore produced and to render each coil independently removable fromlthe headers so that repairs may be more expeditiously and economically made without requiring the dismantling of the entire radiator.
Another'object of the invention resides in providing an improved jointed structure ,between the ends of the coils andthe headers forming a substantially leak-proof union and providing an assembly which may be applied to existing forms of radiator headers without requiring substantially 1 any modification or alteration therein.
Further objects-of the invention are to I provide an inexpensive radiator construction having a comparatively large surface exposure to the cooling airin order that the water may at all times be kept cool and an active circulation promoted such as w1ll prevent any likelihood of overheatiryg or of abnormal temperatures in the motor.
With these and other objects in view the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.
. part of this application, and in which sim1-' In the accompanying drawings forming a Serial No. 475,569.
F1g. 4@ 1s a fragmentary perspective view of a sect on of one of the coils. Referring more particularly to the draw- 1ngs, wher e1n only.a single embodiment of the inventlon is disclosed, the improved radiator consists of a pair of headersl and 2 whlch are preferably disposed vertically one above the other with an intermediate space occupled by a number of coils 3 which com- .municate at their ends respectively with the two headers and form a portion of the circulatory system therewith. The upper header 1 is provided with the usual filling nut 4 closed by the screw or other cap 5 and it also is equipped with a short neck of pipe 6 to which is attached the hose, coupling the radiator with one portion of the water jacket of the engine. The lower radiator 2 is in a similar manner formed or otherwise prodiiced with a short section 7 of pipe neck adapted to couple to the hose extending to the lower portion of the engine waterjacket,
the circulation of the water taking place in the usual way.
I A mesh 8 is preferably stretched across in front of the coils 3 between the headers 1 and 2 and the mesh may be of any suitable design, for instance to simulate the front portions of the usual automobile radiators.
tity of air to the coils 3. In some cases it may also be desirable to stretch a screen or mesh fabric 9 between the headers 1 and ,2 in rear of the coils 3, such mesh fabrics 8 and 9 further forming protecting guards for the space between the headers to avoid the entrance of foreign matter which is apt to be encountered in the travel of the vehicle. The meshes will be so arranged as to be readily removed or partially detached to give access to the coils 3 for the purpose of their removal or repair. i In Fig. 3 I have illustrated an improve union between the lower wall 10 of the upper header 1 and one of the coils, 3. In accordance with this construction an o ening 11 p i the coils employed and nipples 12 are let down through this opening from the top, they be is made in the base 10 for, each 0 ing provided with flanges 13 which take againstthe inside face'of said art 10. Sol-R ice der, indicated at 1%, is prefer-a 1y employ ed the rapid falling to secure the flange 13 permanently and nonrotatively to the wall 10. The nipples are each threaded exteriorly at their lower ends as indicated at 15, which ends project beneath the horizontal plane of the wall 10 and the lower ends of the nipples are formed with beveled faces 16 which are substantially frusto-conical to receive the similarly formed cone frustum 17 on a head carried by the upper end ofthe coil 3. An inversely formed conic 'frustum 18 is formed on the lower portion of the head having its base coincide with the base of the frustum 17 and in eflect being an extension thereof in a reverse sense. The latter conic frustum 18 is adapted to take against a similarly formed wall 19 of a packing gland nut 20 having internal screw threads to engage with the threads 15 on the nipple. p' V The nut 20 is flanged as indicated at 21, and snugly grips the coil 3 just below-the head. The flange 13 of the nipple is preferably provided with straight line faces in order to receive a wrench or other tool to hold it against turning when the nut 20-is screwed upon the threads 15, but this is only necessary when the nut is applied before soldering the nipple ,to the header.
As shown more particularly in Fig. 4 the coils 3 are each formed of spirally wound convolutions in any suitable number, the convolutions being fiat or elongated in one direction and having their major axes preferably extending vertical so that the sides or flat portions of the coils are presented to the air currents entering through the screen 8. This alfords a greater surface area for the cooling air to impinge against and results in of the temperature of the water-in the coils.
As shown in Fig. 2 the coils 3 are preferably mounted in two separate rows extendlng transversely of the vehicle and the coils ofthe respective rows being arranged in staggered relation. he coils are spaced apart transversely so 1: at the air may enter between adjacent coils of the front row to strike the vertically elon ted and flat walls of the convolutions of t e rear coils which lie 'ust behind the spaces between said front coi s. The coils as shown in Fig. 1, preferably. have, their convolutions open or arranged on a relatively wide pitch, this for the purpose of providing large air spaces in andabout the coils for the rapid circulation of the cooling air. This air is, of course, received in great "quantities owing to .the wldth and breadth of theradiator and to the speed of the vehicle, and it is desirable,
to have the coils so arranged that they will permit of a rapid interchange of air.. Particularly is this'desirable in hot weather when the temperature of the air consequent upon the interchange of the heat will rise in temperature. It is therefore necessary to and a readily detacha falls the water further descends in the coils '3 until it arrives at the lower header-.2 when it is in an initially cool state ready to pass back into the lower portion of the water jacket to be again circulated therethrou h ..and utilized for cooling purposes. With t e arrangement of the coils mounted in staggeredrelation and with 0pen convolutlons subject to a large amount of air currents and by reason of the flat nature of the helix,
the water will be more quickl reduced in temperature and more effective y cooled and will result in a more rapid circulation of water throu h the system, preventing at all times, even in the hottest climates and temperatures, the boiling of the water or its rise above a desirable temperature. 'Of course this will be followed by a better action of the motor. r
enever repairs become necess the front screen 8 is removed or swun aslde to give access to the coils and the in ured 0011 may be quickly detached by unscrewing the gland nut 20 from the nipple 12. The nut ma be slid along the coil, a suitablylarge and comparatively straight neck being provided to permit the upper'end of the nut 20 to clear the lower end ofthe nipple. The coil is preferably formed of some such metal as copper'having a slight springing action :or at least possessing sufiicient' ductility to permit of a slight bending of the neck or a springing thereof in removing the upper conic frustum 17 from the beve ed end 16 of the nipple.
'The lower ends of tlie coil are preferably secured in the lower header 2 in a similar manner to that shown in Fig. 3 for the '11 per header and,'if desired, the lower end 0 the coil may in a similar manner be removed. In this case the entire coil with its head and ackingnut gland forms a -unitaassemb y which may be' substituted or rep aced by a like assembly, and the amembly 'ust withdrawn may beretained at a repair s op for inspection-and repair at leisure.
The conic frustfirns 17 and 18 form in conjunction with the end of the nip leand the wall 19 of the packin nut. an e ective seal ble union, and if desirable like packing may be placed between the faces; for instance, the faces 18 and 19.
The formation of the faces 16 and 17 will also assist in the movement of the coil head out of the nipple.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:
1. An improved radiator comprising headers, coils extending between the headers and in communication therewith, said coils being composed of convolutions made substantially flat in a direction at right angles to the direction of movement of the air currents thereagainst, and means whereby the headers may be connected in the circulatory system of the motor.
2. An improved radiator spaced apart headers havingmeans to in clude them in the circulatory system of a motor, and a number of coils extending be-- tween and in communication with the headers and being exposed to cooling fluid currents, said cells being composed of a comprising suitable number of convclutions wound on a I substantially wide pitch having large spaces between and aboutthem for the circulation of the cooling fluid, said convolutions being also elongated in a direction at rifght angles to the directions of movement 0 the cooling fluid currents. 3. An improved radiator comprising a pair of headers spaced apart and included 1n the circulatory system of an internal combustion engine and a plurality of rows of coils connected between and communicating with the headers, said coils being spaced apart and the coils of the respectlve rows being arranged in relatively staggered relation whereby to expose all of the coils to the action of the cooling air currents, the convolutions of the coils being made open and with flat faces presented to the air current.
In testimony whereof I afix my si ature.
