RADIATOR CAP.

Application filed November 15, 1922. Serial No. 601,118..

To al] whom it may concern.'

Be it known that we, TILLMON H.` PEAR- son and GEORGE BINFORD BAYBURN, citizens of' the United States, residing at Waco, in the county of McLennan and State of Texas, have invented certain new and useful improvements in Radiator Caps, of which the following is a specification.

This invention relates to caps, designed primarily for use in connection with radiators for motor vehicles, but it is to be understood that a cap in accordance with this invention, can be employed for any purposes wherein it is found applicable, and the invention has for its object, to provide, in a manner as hereinafter set forth, a cap for radiators formed with means whereby the cap is permanently secured to the radiator and further having means to enable the quick and ready filling of the radiator when occasion so requires, without the removal of the cap, under such conditions preventing the displacement or accidental losing of the cap, to be equally applicable for use for protection of motormeters.

Further objects of the invention are to provide a radiator capwhich is simple in construction and arrangement, strong, durable, efficient vin it-s use, conveniently operated, readily set up with respect to the radiator, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views Figure 1 is a front elevation, broken away, of a radiator of a motor vehicle, showing the adaptation therewith of a cap in accordance with this invention,

F ig. 2 is a sectional plan with the cap open to permit of the filling of the radiator,

Fig. 3 is a view similar to Fig. 2, with the cap closed,

Fig. 4 is a section on line 4-4 of Fig. 2.

Referring to the drawings in detail, 1 denotes a radiator, formed with a filling opening 2.

Secured to the top of the radiator 1 and surrounding the filling opening 2, is a closure cap, in accordance with this invention, for the said filling opening 2, and said cap comprises a cylindrical neck 3, formed :it its lower end with a lateral flange 4, which is secured in any suitable manner to the radiator 1. The neck 3, or which may he termed a filling tube, is offset as at 5, to provide-a shoulder 6 intermediate the ends thereof.. The offset portion 5 of the neck, is formed at the outer end thereof, and which terminatesin an integral top piece 7, upset as at 8 to provide a stop. The top piece 7 is furthermore provided with an entrance opening 9 for the neck or tube 3. Associated with the neck or tube 3, as well as being shiftably connected therewith, is a closure cap 10, formed with a depending annular flange 11, which is inset as at 12, to provide a shoulder 13, the latter bearing against the shoulder 6. The insetting of the flange 12, in connection with the shoul ders G and 13, provides means for permanently connecting the closure to the neck or tube. The closure 10 is formed with an opening 14, adapted when the closure 10 is shifted, to register with the opening 9, so that the radiator 1 can be filled when occasion so requires. The closure 10 is furthermore provided with an arcuate guide 15, into which extends the stop 8, whereby the shifting movement of the closure 10 is limited in either direction, due to the fact that the l stop 8 contacting with either of the end walls of the guide 15 arrests the shifting movement of the closure 10.

Formed integral with the closure 10, is a vertically disposed thumb or finger piece employed for the shifting of the closure 10 when occasion requires, and said thumb or finger piece consists of a T-shaped rodl, havilng a fiat disk 17, formed integral therew1t The normal position of the closure is as shown in Figure 3, and when in such position, the opening 14 is arranged at a point of two hundred seventy degrees with respect to the circumference of the closure. The normal position of the opening 9 is at one hundred eighty degrees with respect to the circumference of the neck or tube 3,

whereby when the closure is in normal position, the opening 9 is closed, but when it is desired to fill the radiator, the closure is shifted until the opening 14 registers with the opening 9 and when so positioned, the radiator is filled.

The closure is permanently connected to the neck or tube 3, and by this arrangement, there is no possibility of the closure being accidently misplaced or lost.

From the foregoing description taken in connection with the accompanying drawings, the radiator cap is set up which is permanently connected with the radiator, and which can be conveniently operated, so that the radiator can be filled when occasion so requires, and although the drawings illustrate the preferred embodiment of the invention, yet it is to be understood that changes'in the details of the construction can be had without departing from the spirit of the invention as claimed.

Vhat is claimed is l. A device for the purpose set forth comprising a hollow cylindrical neck having its outer portion of greater diameter than its remaining portion thereby providing a flat right angularly disposed peripheral shoulder intermediate' the ends thereof, said neckV Y ranged shoulder abutting against the shoulder of the neck for permanently connecting the cap and neck together, said cap having a circular opening adapted to register with the opening in said top and further provided with an arcuate guide into which extends said stop, said guide being of a length Y to obtain a complete quarter turn of the cap with respect to said top, and an upstanding actuating means connected to said cap centrallythereof, said stop and guide limiting the shifting movement of the cap.

2. A device for the purpose set forth comprising ahollow cylindrical neck having its outer portion of greater diameter than its remaining portion thereby providing a dat rightangularly disposed peripheral shoulder intermediate the ends thereof,'said neck provided with an integral top formed with a circular opening and further upset to form a stop, said opening and stop being diametrically opposed, a shiftable closure cap including a depending annular iange having the inner portion thereof inset to provide a flat right angularly disposed inwardly arranged shoulder abutting against the shoulder of the neck for permanently connecting the cap and neck together, said cap having a circular opening adapted to register with the opening in said top and further provided with an arcuate guide into which extends said stop, said guide being of a length to obtain a complete quarter turn of the cap with respect to said top, an upstanding actuating means connected to said cap centrally thereof, said stop and guide limiting the shifting movement of the cap, and said guide formed from an upset portion of said cap and having one end thereof disposed diametrically with respect to the opening in the cap.

3. A device for the purpose set forth? comprising a hollow cylindrical neck having an expanded outer portion thereby pro,- viding a flat right angularly disposed peripheral shoulder intermediate the ends of the neck, said neck further having the top formed with an opening and further formed with an upset integral polygonal portion providing a stop, a shiftable closure cap mounted on the neck and formed with a flange having a contracted inner portion overlapping the fiat shoulder of the neck whereby the latter and the cap are permanently connected together, said cap formed with an opening and further formed with an integral upset portion providing an arcuate guide of a length to obtain a complete quarter turn of the cap with respect to said top and into which extends said stop, said guide having a closed top and ends, said guide and stop limiting the shifting movement of the cap, and upstanding means centrally of and formed integral with t-he cap to provide an actuating element for the closure.

In testimony whereof, we aIiX our signatures hereto.

GEORGE BNFQRD RAYEURN. TILLifO-N H. PE'ARSGN.
