WILSON, 0E FLINT, MICHIGAN, AssrenoR TO GENERAL MOTORS co'nroRArrolv, 0E DETROIT, MICHIGAN, A CORPORATION 0E DELAWARE THERMOSTAT MOUNTING Application filed March 12, 1928. Serial No. 260,977.

The invention relates to fittings for the mounting of thermostatically actuated control valves. It is especially designed for, and will be herein described as applied to, the mounting of such valves in the cooling sys tems of water-cooled internal combustion engines.

One object of the invention is to provide for the housing of the valve and its actuating mechanism wholly within a fitting or pipe connection, the assembly constituting a unit readily attachable to or detachable from the engine. Other objects and advantages will appear from the following description taken in connection with the accompanying drawings in which:

Figure 1 is an elevation partly in section showing one embodiment of the invention.

Figure 2 is an elevation showing the fitting of housing illustrated in Figure 1.

Figure 3 is a perspective view of the clip illustrated in Figure 1, and

Figure 4 is a View similar to Figure 1 but showing a slightly diflerent embodiment of the invention.

Referring to the drawings, 5 indicates the upper portion or head of the cylinder block of an internal combustion engine which will be provided with the usual spaces constituting a water jacket. The water jacket communicates with an outlet passage 7 formed in the projecting portion 8 of the block, which portion is provided with an outwardly facing seat 9.

The valve housing is constituted by a fitting comprising a body portion 10 adapted to receive within it and Wholly enclose the valve unit. On the interior of the body is an annular flange 11, one face of which serves as a seat or abutment to which the thermostatic valve unit is secured, the aperture surrounded by the flange being the passage through which flows the cooling medium whose flow is to be controlled by the valve.

The upper end of the body 10 is reduced, as at 13, to receive a suitable hose section or other conduit whereby the cooling medium may be conducted to a cooling receptacle such as an ordinary automobile radiator. The lower portion of the body is formed with a flange 14 adapted to fit against the face 9 of i the water jacket outlet 8. Holes 15 in the be inserted into the lower end of the body 10 and to seat upon the annular abutment provided by flange 11. As illustrated, it comprises a frame having an annular flange or head 18 seating against the flange ll'of the housing. A valve member 19 operably connected to a thermostat 20 controls the opening in the head 18 in the manner usual with this type of thermostatic valve.

The valve unit is secured to the housingb a clip which may be of the form shown in Figure 3, comprising a U-shaped plate having' the extremities of its arms 21 bent,'as

at 22, to constitute clamping lugs. A flange 23 is bent over at the base of the plateto serve as a fulcrum. Holes 24 permit the pas-, sage of screws 25 which, by engagement with holes 26 in. the housing, serve to secure the plate to the housing.

In assembling the parts, the valve unit'12 is first placed in position with the'head 18 seated against the abutment 11, a gasket 27 being preferably interposed. The clip is then positioned with lugs 22 resting on the head 18 on opposite sides of the valve and flange 23 resting on the lower face of the abutment. The screws 25 are then inserted, thus securely clamping the valve unit against the abutment.

In the form illustrated in Figure 4, the valve unit 12 is clamped against the annular abutment 11 on the interior of the body 10 by a clip comprising a plate 30 having one end bent, as at 31, to engage the valve unit.

The other end of the plate is secured to the interior of the housing by one or more screws, as indicated at 32, whereby the valve unit is secured against the abutment 11.

It will be understood that other changes and modifications may be made without departing from the spirit and scope of the invention and, therefore, it is not intended to limit the scope of the invention to the specific details herein disclosed except as re quired by the language of the appended claims in View of the prior art.

I claim: 1 1. The combination with ahousing having a passage therethrough and an annular internal abutment surrounding said passage, of a thermostatic valve unit positioned Within said housing and having an annular head seated upon said abutment and .a slip positioned to clamp said head against said abutment. i i 2. Structure as set forth in claim 1, said clip comprising a plate having lugs engaging the head of said unit, said plate being removably secured to the housing- 7 1,3,. The combination with an internal com- .bustion engine block having .a water jacket andan outlet from said jacket ofa fitting secured {to said engine bloek over said outlet, said fitting comprising a housing having a passage therethrough with a restriction there- ;5 in providing an annular shoulder, a thermostatic valve innit comprising a frame having an annular flange positioned on said shoulder and valve 1 means adapted to control flow through said passage, and removable means 0 contained within said housing for clamping the flange of said uni-t against said shoulder. 4. The combination with the cylinder block of an internal combustion engine having .a water jacket and a water outlet therefor of a5 a fitting having an inner end portion secured to said block andhaving an internal passage in comnnmication with said outlet and a reduced outerend portion adapted to receive a hose, theinterior of said fitting being proded with an annular flange, .a thermostatic valve member having a head seated on said annular flange, said member being insertable into said fitting through said inner end portion and securing means comprising a iclipsecured to said fitting and having an arm portion engaging said head and the same against said annular flange :In testimony whereof I aifix msignature.
