This invention relates to motor vehicles or the like, and particularly to an improvement in the arrangement and location of parts of a conventional ignition system for internal combustion engines.

The invention aims to provide for the mounting of the coil box in an easily accessible position, to facilitate assembly and subsequent inspection and repair, and in convenient proximity to the usual distributor mechanism, to make possible the use of short lead wires between the coil andl distributor, which in addition to reducing costs materially enhances the general appearance of the assembly.

The invention also contemplates the removal of the coil, as far away as possible from the vehiclebody, for the purpose of reducing interference to radio reception in those cases where the vehicle isequipped vfor radio communication.

A further and important obj ect is to so locate the coil as to save it from the harmful effects ofintense and excessive heat conditions that sometimes prevail near the engine and beneath the engine hood.

It is proposed, according to a preferred embodiment of the engine, toniount the coil box adjacent the top of the usual radiator that forms part of the engine cooling system, and preferably with at least a portion thereof projecting intoa pocket formed in the rear wall of the top header or tank ofthe radiator structure. In this fashion the maximumtemperature, to which a coil is subjected, is'greatly reduced, the temperatures being less than 212o F. at all times, and more generally around 1600` F. as compared with temperatures often exceeding 300 F .Y at high speed on a summer day, to whicha coil is subjected when mounted near the engineaiid under the hood in the usual manner, and which eXtreme temperatures have been the cause of frequent coil failures in the past. I Y

A better understanding of the nature of the invention will be had upon reference to the accompanying drawings illustrating a preferred embodiment incorporated as standard construction in the Cadillac V-16 automobile, and wherein Figure 1A is a top' plan 1930. semi No. 461,069.

view of an engine and its associated parts; Figure 2 is an elevation, looking in the direction'of the arrows on line 2-2 of Figure 1, and Figure 3 is a sectional view taken on line 3-5 of Figure 2.

Referring to the drawings, the numeral 1 indicates an internal combustion engine hav- Ing two banks or rows 0I cylinders arranged in angular or V relation, and being mounted in any suitable fashion in the usual chassis frame forward of the dash board 2 of the vehicle body. This engine is j acketed for the circulation of water or other cooling medium, to absorb the heat 0f combustion, and the jackets communicate withv a cooling radiator, forming a part of the engine cooling circuit, where the heat is dissipated as. it passes through the radiator. As usually constructed, the radiator comprises a pair of spaced tanks and an intermediate core or heat dissipating unit, through which water `iows from tank to tank, Figure 3 showing a fragment of the core unit, which is indicated at 4, and the upper tank or inlet header 5. For appearance purposes, the radiator structure is incased in an ornamental shell or housing 6, shown as being provided at its rear fedge witha depressed portion 7, that forms a ledge or rest for the forward end of the engine bonnet or hood (not shown). In the present case,

the radiator structure is provided with an additional appearance shell or member 9, secured at its forward end to the hood ledge 7, and covering the rear face of the upper tank 5, and if desired, projecting downwardly the engine with their rearward ends projecting through the dash board 2,. and -carrying screw threads for adjustable attachmentto the dash board, as by means of nuts 15, threaded thereon. The angular relation of Aalong the sides ofthe main shell 6, to afford i i the tie rods serves to etfectively brace the top portion of the radiator against movement in all directions, and the adjustable connections between the rods 14 and dash board 2, permits slight variations in the relative position of the radiator to eti'ect a proper and neat littiiig of the engine hood and alignment of the several associated parts.

ln addition to their iunction o bracing the radiator, the tie rods lll, which may be toi-med or hollow tub.ng or the like, provide conduits for the passage of electric wires or current conductors leading to or from a point within the body of the vehicle, for connection, as ior example, with a switch or indicator mounted on the customary instrument panel. ln the drawings, such wires are indicated by the reference numeral 17 and they may constitute a part of the engine ignition system which is shown as including a pair of coil boxes 18, and an engine driven distributor 19, located on top of the engine at the front end thereof.

lt will be understood that one or more coils may be utilized, depending upon the character of the ignition system, and the coil enclosing box or boxes may be located just above the distributor 19, and mounted on the radiator structure. According to Figure 2, use is e made of the bracket ll tor securing the coil boxes in place, and for this purpose the bracket is provided with a pair or' spaced openings or eyes, deined by iorwardly projecting annular' langes 22, the lianges o the two openings being split at points adjacent each other, with corresponding ends connected by a pair of

webs

23 and 24. Aligned openings are provid-ed in the two connecting

webs

25 and 24, to receive a screw stud 25, and one vof the openings may be threaded to receive the threads ot' the screw stud, so that upon adjustment of the stud the rings can be contracted about the coil boxes, with the orward ends of the rings in engagement with an annular locating bead 27 oi the boxes, whereby each box is positively clamped in proper position.

To prevent the action of excessive heat on the coils, the upper header or radiator tank 5, vis extended rearwardly as at 30, and the rear wall of the extension is provided with a pair 'of depressions as at 31, in registry with the openings in the bracket 11, to form pockets that receive the forwardly projecting portions of the coil boxes. Vmajor portion of each coil extends into a de- In this manner the pression in the upper header and is thus protected from the intense heat such as would cause it to deteriorate and break down. The

lnient, with only the heads of the coil boxes "exposed to observation, and these being located in close proximity to the distributor to permit the use of short wires leading to the distributor, with the current conductors leading to the ignition coils concealed in the tie rods.

W'hile the invention has been specifically described in its preferred embodiment, it will be understood that various modifications can be readily made, as will be apparent to those skilled in the art, without departing 'from the spirit and scope of the appended claims.
