Description
April 20, 1937. J. SINKO CAP FOR FILLING NOZZLES Filed Sept. 25, 1955 John 502, 40,
Patented Apr. 20, 1937 UNITED STATES PATENT 4 Claims.
This invention relates to closures or caps for filling nozzles having reference more particularly to the filling nozzles of automobile gas tanks.
The cap of the present invention quite closely follows the structural features of a fillingnozzle cap disclosed and claimed in my pending application Serial 7l0,789 filed February 12, 1934, but embodies an improvement thereon.
The construction disclosed in my aforesaid application includes a steel spring locking bar that is clamped to the under side of the cap and is formed with downwardly inclined end portions, the tips of which pass through slots in the usual internal flange of the nozzle. The locking bar is secured by a fiat rivet that passes through a central longitudinal slot in the locking bar, the purpose of the employment of a fiat rivet of substantial width engaged with a longitudinal slot in the locking bar being to prevent any relative turning movement of the bar and cap, so as to insure the locking of the cap to the nozzle by the bar when the cap is turned.
Experience has shown that this comparatively long longitudinal slot in the locking bar to accommodate the flat rivet unnecessarily weakens the bar and also limits the degree of spring in the projecting ends of the bar; and the object of the present invention is to provide an improved construction by which the longitudinal slotting of 30 the locking bar is dispensed with, and the degree of elasticity or spring in the arms of the bar is increased.
A practical embodiment of the invention is illustrated in the accompanying drawing, in
Fig. l is a sectional view of the upper portion of a filling nozzle and the cap applied thereto, taken on the offset line ll of Fig. 2.
Fig. 2 is a similar view in a plane at right angles 40 to that of Fig. 1.
Fig. 3 is a bottom plan view of the cap as shown in Fig. 2, in horizontal section through the filling nozzle.
Fig. 4 is a group view showing the parts of 45 the cap disassembled.
55 flange 12 with which the cap or closure interlocks under a partial turning movement of the cap.
The cap, as disclosed in my former application .abo-ve identified, is a two-part cap consisting of an outer disc l3 having a depending peripheral flange l4, and an inner disc 55 formed with anupturned peripheral flange that is interlocked with the inner flange 94. The inner disc I5 is formed with a shallow countersunk portion l5, over the outer. portion of which is fitted a hollow sheet metal boss 11 that is'formed with an upwardly offset bottom wall it. Thesides of the boss ll are vertically slotted, as shown at B9 in Fig. 6, and extending across the boss and through the slots I9 thereof is a spring steel locking bar 20, the projecting end portions of which are adapted, when the cap is applied, to pass down through slots 2| (Figs. 2 and 3) in the nozzle flange 12 for engagement with the lower edge of said flange in the locked position of the cap. As indicated in Fig. 2, the lower edge of the flange on either side of each slot is preferably slightly inclined to provide a cam surface for engagement by the ends of the locking bar as the cap is turned, although this feature is not essential.
The countersunk central portion iii of the inner disc l5, and the bottom wall N3 of the boss I! are formed with registering narrow slots 22 and 23 respectively, and the locking bar 28 is formed in each side edge with a central narrow notch 24 so shallow that it does not appreciably weaken the bar. 25 designates a relatively thin and wide flat rivet formed with a pair of spaced legs 26 and squared hips 21 on the outer sides of the legs. 28 designates a round fiat washer that seats on the countersunk central portion P5 of the inner disc l5, and is formed with a pair of holes 29 spaced to fit the legs 25 of the rivet 25. In assembling the parts, the legs 26 of the rivet are passed upwardly through the slot 23, the notches 24 of the locking bar, the slot 22, and the holes 29, with the hips 2! of the rivet engaged with the under side of the bottom wall l8 of the hollow boss l1, and the upper ends of the legs of the rivet are then swaged over, as indicated in Fig. 2, whereby the parts are securely united, and the locking bar 2!! cannot escape or turn relatively to the cap by reason of the engagement of its notches 24 with the legs of the rivet.
' Encircling the hollow boss I! and bearing against the under side of the disc [5 is a comparatively thick fiber or leather washer that seats on the top of the filling nozzle II. The
parts are so proportioned that when the cap thus seats on the top of the nozzle, the end portions of the locking bar 20 will have passed through the slots 2| with their upper surfaces substantially flush with the free edge of the nozzle flange. To facilitate engagement of the ends of the looking bar with the nozzle flange, the upper surfaces of said ends are slightly convexed transversely, as shown at 20 in Fig. 5, sothat the ends of the locking bar will, under a turning movement of the cap, readily engage with the lower edge of the flange, and where this lower edge is given a low cam formation, as indicated in Fig. 2, as the cap is turned, the locking bar will be slightly sprung downwardly thus insuring a tight, leakproof fit of the cap on the nozzle, and although, as shown in Fig. 1, the central horizontal portion of the locking bar overlies and rests upon the central wall l8 of the hollow boss ll, this wall will yield downwardly sufficiently to permit a spring action in the locking bar substantially from its center to each end;a feature impossible in the construction of my former application by reason of the fact that substantially the entire fiat central portion of the locking bar is gripped by the flat rivet.
I claim:
1. A cap for a filling nozzle, comprising outer and inner discs united at their peripheries, a central boss depending from said inner disc, a looking bar extending through said boss, said looking bar having notches in its side edges so shallow as not to appreciably weaken said bar, and a rivet having a pair of legs extending through said boss and inner disc and the notches of said locking bar.
2. A cap for a filling nozzle, comprising outer and inner discs united at their peripheries, said inner disc formed with a central countersunk portion, a washer seated in said countersunk portion, a central boss depending from said inner disc, a locking bar extending through said boss, said locking bar having narrow notches in its side edges so shallow as not to appreciably weaken said bar, and a fiat rivet having a pair of legs extending through said boss, the notches of said locking bar, said countersunk portion, and said Washer, and swaged over on the latter.
3. A cap for a filling nozzle, comprising outer and inner discs united at their peripheries, said inner disc formed with a central countersunk portion having a slot, a washer seated in said countersunk portion having a pair of holes, a central boss depending from said inner disc having a slot, a locking bar extending through said boss having narrow notches in its side edges so shallow as not to appreciably Weaken said bar, and a relatively thin and wide fiat rivet having a pair of spaced legs extending through the slot of said boss, the notches of said locking bar, the slot of said countersunk portion and the holes of said washer and riveted over on the latter.
4. A cap for a filling nozzle, comprising outer and inner discs united at their peripheries, a
central boss depending from said inner disc, a locking bar extending through said boss, said bar having spaced openings, and a rivet having a pair of legs extending through said boss and inner disc and the spaced openings of said locking bar in inter-fitting engagement with said openings, whereby said bar is locked against turning relatively to said discs.
JOHN SINKO.
