G. L. CHAPEL RADIATOR CAP OR THE LIKE Filed Nov. 3, 1927 IIIIIIIIIVIIIIII'III INVEN TOR 17 TTORNEYS Patented Aug. 28, 1928.

UNITED STATES PATENT OFFICE.

GEORGE LEHMAIN CHAPEL, OF GRANT) RAPIDS, MICHIGAN, ASSIGNOR TO W. B. JARVIS COMPANY, OF GRAND RAPIDS, MICHIGAN.

RADIATOR CAP OR THE LIKE.

Application filed November 3, 1927. Serial No. 230.805.

The main object of this invention is to pro vide a closure for radiators of automobile", tanks and. the like which may be readily removed to permit filling, the cap. hmvever be ing permanently connected with the radiator or tank so that it cannot become lost.

A. further object is to provide a connect-ion for the cap to the neck of the receptacle which permits the tree engagement and disengagement of the cap by means of screw threads or other equivalent means.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure embodying the teatures of my invention is illustrated in the accompanying drawing forming a part of this specification, in which:

Fig. 1 is a plan view of a radiator cap em bodying the features of my invention.

Fig. 2 is a fragmentary view partially in vertical central section, the cap being shown in closed position by full lines and in open position by dotted lines.

Fig. 3 is a detail view partially in section on line 3-3 of Fig. 4, showing details of the flexible link connection for the cap to the radiator neck.

Fig. 4 is a detail view partially in section on line 4-4 of Fig. 3, parts being broken awa to better show the structure.

Fig. 5 is a detail view partially in vertical central section of a slightly modified embodiment of my invention.

Fig. 6 is a plan View of the swivel retaining member of the modification of Fig.

Referring to the drawing, 1 represents the neck of a radiator which is externally threaded at 2. The cap 3 is internally threaded at 4 to coact with the threads of the neck. This cap has. an inwardly facing central socket 5, the walls of which have an annular groove 6 therein.

The anchoring ring 7 is disposed within the neck. This ring is split at 8 and provided with an expanding member 9 whereby it is expanded and clamped into the neck. becoming a permanent part thereof. The expanding means is preferably that illustrated and described in my application for Letters Patent filed October 15, 1927, Serial No. 226.394.

The anchoring member is placed within the neck with its upper edge flush with the upper edge of the neck and coacting therewith to provide a seat for the gasket 10. The cap is connected to the anchoring member by a suitable flexible connection which permits rotating; the cap to attach and remove the same and the swinging ot' the cap to one side of the neck as shown by dotted lines in Fig. 2.

This connection consists of a pair of links 11 and 12 and a swivel member 18 rot-atably secured in the socket The link 2 is a double link, that is, it is formed of a pair of side members 14 which are provided with opposed pivot lugs 15. the link 11 being arranged be tween these side members 14 at one end and having a hole 16 therein to receive one pair of the pivot lugs. The swivel member has an car 17 arranged between the opposite ends of the link side members and havinga hole therein to receive the other pair of pivot lugs.

The side members are secured upon the spacing block 18 by spot-welding thereto as indicated at 19. The links are thus connected to each other and to the swivel member by means which cannot be disengaged without substantially destroying the structure.

The link 11 is pivotally connected to the anchoring member at 20. The swivel member has a transverse bore 21 therein adapted to receive the pins 22 which are held in engagement with the annular groove 6 in the swivel socket by the spring The spring is collapsed to permit the swivel member to be in serted in the socket. hen the pins are engaged with the socket a concealedconnection is provided for the cap to the links.

In the embodiment shown in Figs. 5"and 6 the swivel member 24, corresponding to the swivel member 13. has an annular groove 25 therein adapted to receive the coiled spring 26, the groove 25 being of such diameter that a spring may be compressed therein to permit the insertion of the swivel member into the socket the spring expanding into the groove 6 when brought into alinement therewith as shown in Fig. 5. thereby rotatahly securing the cap to the swivel member.

In the embodiment illustrated I provide a closure plate 27 which is preferably of spring material. This plate has a central opening 28 therein to receive the swivel member, the swivel member having a shoulder 29 holding the plate against the central depending pertion 30 of the cap. The closure member is thus supported to engage the gasket 10 preventing the passage of steam and water over the gasket and escaping between the threads.

Further, when'formed of spring material this closure member serves as a means for holding the cap in its adjusted positions on the neck. This is not only desirable in preventing the cap from working loose, but, in the event the cap is provided with projecting ornamental parts, such parts may be properly alined.

I have illustrated and described my improvements in simple embodiments thereot. I have not attempted to illustrate or describe certain other embodiments or adaptations which I contemplate as I believe this dis-- closure will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: I

1. The combination of an externally threaded neck, a cap internally threaded to coact therewith and having a central inwardly facing swivel member socket provided with an annular groove, an anchoring member withinsaid neck, a-swivel member having a transverse bore therethrough arranged in said socket, retaining pins arranged in said bore in said swivel member to engage said groove of said socket, a spring disposed between said pins yieldingly supporting them in groove engaging position, and links pivotally connected to each other, one of said links being pivotally connected to said swivel member and the other to said anchoring member.

2. The combination of an externally threaded neck, a cap internally threaded to coact therewith and having a central inwardly facing swivel member socket, an anchoring member within said'neck, a swivel member arranged in said socket, means for retaining said swivel member in said socket, links pivotally connected to each other, one of said links being pivotally connected to said swivel member and the other to said anchoring member, a gasket engaging the end of said neck, and a closure plate disposedwithin said cap to engage said gasket and having a central opening therein to receive said socket meniber, said socket member being shouldered to support said closure plate.

3. The combination of 'an externally threaded neck, a cap internally threaded to coact therewith and having a central inwardly facing swivel member socket provided with an annular groove, an anchoring member within said neck, a swivel member arranged in said socket, a retaining member for said swivel member engaging said groove of said socket, links pivotally connected to each other, one of said links being pivotally connected to said swivel member and the other to said anchoring member, a gasket engaging the end of said neck, and a closure plate disposed within said cap to engage said gasket and having a central opening therein to receive said socket member, said socket member being shouldered to support said closure plate.
