AUTOMOBILE RADIATOR CAP.

Application filed November 3, 1924. Serial No. 747,432.

To all whom t may concern:

Re it known that I, ALoYsrUs C. LIPPERT, a citizen of the United States, residing in Kenosha, in the county of Kenosha and State of IViScOnSin, have invented a new and useful Improvement in Automobile Radiator Caps, of which the following is a specification.

rlhe present invention relates to closures for automobile radiators and the like, and has for a principal object the provision of a radiator cap having the general advantages described and claimed in copending application Serial No. 747,434, of Aloysius C'. Lippert and Anthony H. I-Iackl, and in addition thereto having provisions for attachment to the radiator neck which facilitate adaptation of the cap to radiator necks of dierent size.

A. further object ofthe invention is the provision of a radiator cap of the general type of the copending application above referred to, provided with sealing means which may, perhaps, be preferred to that shown in said co-pending application and which sealing means, as well as the remainder of the construction, may be inexpensively provided so that vthe cap may be placed upon the market at relatively low cost.

Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, whiclntaken in connection with the accompanying drawings, discloses a preferred embodiment thereof Referring to the drawings,

Figure 1 is a front elevation of a radiator cap in which the invention is embodied, the same being shown in position upon the filler neck of a radiator and being partially broken away and sectionalized for convenience in illustration; and

Figs. 2 and 3 are horizontal sectional views, taken respectively upon the section lines 2-2 and 3-3 of Fig. 1.

In said drawings, I have shown, for illustrative purposes only, a preferred form of my invention, in which the reference character 11 indicates an outer body, having laterally extending arms 12 and being provided with a hinged cover 13, adapted to carry a motometer 14, or like device, a latch 15 being provided to hold said cover tightly to the body and in contact with a gasket 16,

of rubber or like material, suitably posit-ioned upon the interior of said body. An inserted locking member 17, of brass or like workable material, is disposed in a central opening 18 in said body and in the present instance is adapted to be locked to said body by means of integral projections 19, extending into a circular groove 21 formed on the interior of the cap body, it being apparent that with this construction, said body may be rotated relatively to the insert, but separation of the parts is prevented and the rotation ofl the body will not tend to remove said insert from the radiator neck. Said insert 17, at the lower end thereof, is bent back upon itself, as indicated at 22 and .the inner, upwardly extending portion 23 thus provided is threaded, as indicated at 24, and adaptedto screw upon the radiator neck 25. The upper extremity of the portion 23 of said insert is bent slightly outwardly, asv shown at 26, and then inwardly andi downwardly to provide an edge portion 27 adapted to tightly contact with the top' of said radiator neck when the insert is screwed down to the position shown in Fig. 1. It will be manifest that the diameter of the threaded portion 23 of thel insert may be varied in accordance with the manner in which said portion is bent from the body of said insert, thereby to accommodate radiator necks `of different size, the diameter of the-body of the insert-being the same for all sizes and the threaded portions being disposed at any desired distance from said body, in manner which will be readily understood. r[hns the inserts may be provided for vattachment to the varying sizes of radiator necks by merely disposing thel threaded portions 23 thereof at dierent distances from the body, the remaining operations and the construction and sizes of the other parts being the same for all radiators.

For the purpose ,of screwing the cap onto the radiator, I employ a ratchet member 28, disposed in a recess 29 in the insert and having a projecting edge part 31 adapted to engage in recesses 32 formed in the outer cap body and engageable when said outer body is ro-tated in one direction only. One of the recesses 32 extends to the bottom of the outer body, as shown in Fig. 1, to facilitate the assembly of the body and insert with the ratchet member 28 in position, and it will be understood that the number of ratchets and of said recesses might be increased, if desired. I prefer, however, to provide said recesses at opposite sides of the cap., inwardly from the projecting arms 12, as shown in the drawings, since there is more stock in this area and the grooves` are less likely to weaken the cap body.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

l. A radiator cap for automobiles or the like, comprising an outer body, and an inserted locking member secured thereto and permitting relative rotation of the outer body, the lower end of said inserted member being bent inwardly within the body portion thereof and threaded ier attachment to the radiator neck.

2. A radiator cap for automobiles or the like, comprising an outer bod", and an inserted locking member secured thereto and aermitting relative rotation of the outer body, the lower end of said inserted member being bent inwardly within the body portion thereof and threaded for attachment to the radiator neck, and having a part beyond the threads adapted for sealing engagement with the top of said neck.

3. A radiator cap for automobiles or the like, comprising an outer body, a closure pivoted to said body, and an inserted locking member secured thereto and permitting relative rota-tion of the outer body, the. lower end of said inserted member being bent inwardly within the body portion thereof and threaded for attachment to the radiator neck.

4. A radiator cap for automobiles or the like, comprising an outer body, a closure pivoted to said body, and an inserted locking member secured thereto and permitting relative rotation of the outer body, the

lower end of said inserted member being bent inwardly within the body portion thereof and threaded for attachment to the radiator neck, and having a part beyond the threads adapted for sealing engagement with the top of said neck.

5. A radiator cap for automobiles or the like, comprising an outer body, and an inserted locking member formed of bendable material and having a vertical wall and a portion bent upwardly within said wall and provided with means for attachment to the radiator neck.

6. A radiator cap for automobiles or the like, comprising an outer body having. an opening therein, and a locking member disposed within said opening and having throughout a part of its height a double wall, one part of which is provided with means for attachment to the radiator neck.

7,'A radiator cap for automobiles or the like, comprising an outer body having an opening therein, and a locking member disposed mithin said opening and having an attaching portion arrangeable at varying distances from the body part thereof, said attaching portion having an extension engageable with the top of the radiator neck to prevent leakage.

8.Y A radiator cap for automobiles or the like, comprising an outer body having an opening therein, and an inserted locking member having a double wall, one part of which is provided with means for attachment to radiator necks of different diameter without change of form of the body portion of said member.

9. A radiator cap for automobiles or the like, comprising an outer body having an opening therein, and a locking member disposed within said opening and having an attaching portion arrangeable at varying distances from the body part thereof, said locking member having an end flange engageable with the top of the radiator neck to prevent leakage and said fiange being rolled to provide clearance about the outer edge of the radiator neck and to stiifen the flange.
