2 Claims.

This invention relates to an electric heater expressly designed and appropriately constructed for attachment to aninternal combustion engine block, thesame being located between the block and the radiator, this for purposes of heating the water in the' cooling system in an obvious manner.

The purpose of the invention is to serve as a so-called "temporary or overnight heater" and it functions to sufiiciently heat the water to keep it in circulation while the vehicle is in the garage or otherwise parked, whereby to render starting easier during cold weather spells.

In carrying out the principles of the invention I have adopted a simple and economical attachment having a hose and nipple on one side for connection with the radiator, and having nipples on the other side to accommodate complemental hoses connected with the usual expansion plugholes in the cylinder block.

More specifically the attachment comprises a nipple-equipped hose-accommodating cylindrical unit constructed at one end for detachable connection of the electrically heated core element, the latter being such that it can be used in association with either A. C. or D. C. current V scription and the accompanying illustrative draw- In the drawings, wherein like numerals are employed to designate like parts throughout the same- Figure 1 is a side elevational view of a conventional internal combustion engine with radiator associated therewith and showing the improved heater attachment and the manner in which it is constructed and applied.

Figure 2 is an enlarged view, partly in section and partly in elevation of the essential 'parts of the invention.

Figure 3 is a cross-section on the line 3-3 of Figure 2 looking in the direction of the arrows.

In Figure l the motor block or engine, as a unit, is indicated at A and the radiator at B, these being conventional parts. As brought out better in Figure 2, the attachment comprises a substantially cylindrical casing of appropriate material and dimensions indicated by the numeral 4, this being closed at the left-hand end and provided with an internally screw-threaded accommodation neck 5 at the right-hand end. The electric heating element or core 6 fits into the cylinder in spaced relation and is provided with a screw-threaded connection 1 threaded into the neck, this connection being on a nut faced head 8. A gasket 9 is interposed between the parts 5 and 8 to provide the desired fluid-tight joint. The electric conductor cord Ill is provided with a plug II to accommodate a pronged plug I! on an extension cord 13, whereby to provide convenient means for supplying current to the heating element II. It is understood that the particular wiring and method of connecting the wires is not important and is, therefore, not detailed.

On the lower side the casing 4 is provided with a nipple II to which an adjacent end of the radiator hose I5 is connected. The opposite end of the hose is secured to the bottom of the radiator as shown in Figure 1. Similar nipples l6 and I! are arranged on the opposite side, these to accommodatethe shorter hoses l8, which latter hoses are suitably fastened to the nipples and also secured to fittings I9 mounted in the customary expansion plug-holes in one side of the water jacket of the cylinder block, this as brought out in Figure 1.

With the current "on the core element 6 serves to circulate the water through the hoses,

, radiator and cylinder block in an obvious manner, thus keeping it at a temperature suiiicient to avoid freezing and promote pump starting, this inan evident manne r It is thought that persons skilled in the art to which the invention relates will .be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in the shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

Having described the invention, what is claimed as new is:

1. An electric circulatory water heater attachment for conventional internal combustion engine blocks comprising a cylinder, the latter being closed at one end and having a reduced internally screw-threaded neck at its opposite end, said cylinder being provided on the central portion of its normal bottom with a nipple to accommodate a hose for connection with the associated radiator, and being further provided at diametrically opposite points with outstanding longitudinally spaced additional nipples. these to accommodate hose line connections for connection with the customary expansion plug holes in the cylinder block, a screw-plug having an electric heating core element, said core element being located in spaced concentric relation on the interior of said cylinder, said plug being threaded in said neck and being provided with a wrench grip and an electric current-conducting cable.

2. An electric circulatory water heater attachment for conventional internal combustion engine blocks comprising a cylinder, the latter being closed at one end and having a neck at its opposite end, said cylinder bein Provided on the central portion of its normal bottom with a hose for connection with the associated radiator. and being further provided at diametrically opposite points with outstanding longitudinally spaced additional nipples, these to accommodate hose line connections for connection with the customary expansion plug holes in the cylinder block, a plug having an electric heating core element, said core element being located in spaced concentric relation on the interior of said cylinder, said plug being mounted in said neck and being provided with a tool grip and an electric current-conducting cable.
