DEVICE FOR SECURING A HEAD TO A BARREL Filed oct. s, 1951 INVENTOR.
Patented Oct. 23, 1934 DEVICE FOR SECURING A HEAD TO A BARREL Harry C. Wilcox, Milwaukee, Wis., assignor to Pressed Steel Tank Company, Milwaukee, Wis., a corporation of Wisconsin Application October 3, 1931, Serial No. 566,624
l 4 Claims.
This invention relates in general to metal containers or receptacles such as barrels and more particularly to improved means for releasably securing a head or closure in duid tight engagement with the barrel.
One of the principal objects of the present invention is to provide` a device of this character which is readily and easily operable without the use of any special tocls for the purpose of securing the head in fluid tight engagement with the barrel or for the purpose of releasing the head for removal.
Another important advantage resides in the feature of having the device self-locking when it i5 is moved to the position in which it secures the head in fluid tight engagement with the barrel. Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereniafter more fully described, and particularly pointed out. in the appended claims, reference being had to the accompanying drawing forming a part of this specification, and in which:
Figure 1 is a view in side elevation showing a barrel having a removable head equipped with a releasable securing means embodying the present invention;
Figure 2 is a fragmentary view in side elevation on an enlarged scale more clearly illustrating the details of construction of the releasable securing means; l
Figure 3 is a view in horizontal section taken in the plane of line 3-3 in Figure 2 and looking in the direction of the arrows;` and Figures 4 and 5 arefragmentary views in vertical section taken on lines 4-4 and 5-5, respectively, of Figure 2.
Referring to the drawing, the numeral 1 designates a metal receptacle or container shown for the sake of illustration in the form' of a. barrel.
The upper end of the barrel is open and may be provided with a head or rim 2. A head 3 may be applied to the upper open end of the barrel to close the same and has its peripheral portion in the form of a curved flange-like structure 4 adapted to be seated on the bead 2 or on a gasket (not shown) which may be provided on the bead. The head is fastened in position to close the open end of the barrel and to have its flange 4 in fluid tight Contact with the bead 2 by means of a contractible metal clamping ring 5. As shown, the metal ring 5 is made of channel form or concave on its inner side to fit over and engage with the outer side of the ange v4 of the head-3 and the underside of the be d 2 to draw and hold these parts tightly together when the ring is contracted thereon. I'his action of the ring is 'enhanced by constructing the channel in the clamping ring so that it has outwardly converging opposing walls to engage with the bead or rim 2 of 60 the barrel and the flange 4 of the head. 'I'he ring is made contractible by splitting or severing it transversely and is sufiiciently resilient to adapt it to be contracted for securing the head in position and to be expanded for removal. A
The ring is expanded and contracted by means of a specially constructed manually operable toggle organized with the ring in a novel manner. As illustrated, one end of the ring 5 has a lug 6 welded or otherwise suitably secured thereto and projecting downwardly therefrom on the outside of the barrel. A second lug 7 is secured to the ring 5 'adjacent its opposite end' and projects downwardly from the ring on the outside of the barrel. The lug 6 is provided with an opening 75 through which the shank of a stud or screw 8 is adjustably fitted. A nut 9 is threadedly engaged with an end of the shank of the screw which projects beyond the lug and abuts one side of the lug. By turning the nut the stud or screw 8 may 80 be adjusted. 'I'he head of the stud or screw is pivotally connected as at 10 to link members 11. Two link members 11 are provided but they function as a single link. The opposite ends of the link members from those connected to the stud or '85 screw 8 are pivotally connected as at 12 to an intermediate portion of a handle 13. The inner end of the handle 13 is fulcrumed or pivotally connected to the lug 7 as indicated at 14. The free end of the handle 13 is oisetlas at 15 to 90 facilitate grasping thereof in the closed or locked position of the parts. It will be noted from Figure 3 that the manually operable toggle mechanism is so designed that in the position thereof where the toggle contracts the ring to sechre the head to the barrel, the toggle is self-locking, that is to say, the line between the pivotal connections or centers 10 and 12, lies inwardly of the fulcrum or center 14 or between this fulcrum or center 14 and the barrel. The handle 13 and link members 11 are of arcuate form and concentric with the barrel and clamping ring in the closed or locked position of the device. In this way, a compact and practical 105 structure is had and the parts are located substantially within the lateral or peripheral confines of the ring 5 and hence effecting protection thereby. 'Ihe lugs 6 and '7 have their portion which connects with the link member 11 and no handle 13 offset inwardly under the clamping ring 5 for these purposes.
With the head applied to the barrel it may be secured in position by positioning the ring in operative relation to ilange 4 and bead 2 when the ring is expanded and the toggle open. The handle 13 is then pushed inwardly toward the barrel. This causes the pivotal connection 12 to swing in such manner that it exerts a pull to the right, as viewed in Figure 3, on the link members 11, stud 8 and lug 6 and a thrust to the left (Figure 3) on the lug 7 thereby contracting the ring 5 into secure engagement with the ange 4 and bead 2. As the lever 13 reaches the point where the line between the centers 10 and 12 passes the center 14, the strain exerted on the parts causes the handle and link 11 to snap into the locked position shown in Figure 3. The ring 5 may be released and the head removed by grasping the oilset portion 15 of the handle and pulling the handle away from the barrel which results, after the initial movement of the handle, in the handle exerting a pull to the right on the lug '7 (see Figure 3), and a thrust to the left of lug 6, as Viewed in Figure 3, thereby expanding the ring 5. The degree and eiectiveness of the locking action may be regulated by adjusting the nut 9. By having the toggle arrangement organized with lugs which are disposed on the outside of the barrel, the toggle is easily accessible and readily and easily manipulated. And further, it is self-locking in the secured position of the ring 5, The structure is rugged and durable and while` easily manipulated is positive and secure in its locking action and safe against accidental disengagement or release, Although disposed on the outside of the barrel, the device is effectively protected by the overhanging structure of the barrel, bead and clamping ring (see Figures 4 and 5) and is arranged so that any impacts or the like tend to increase the locking effect rather than to release the device.
' In some instances it may be desirable to enhance the character of the fluid tight seal between the head and the barrel. This may be accomplished by applying the clamping ring and bringing it into clamping engagement with the head and barrel in the manner above described. After the toggle has assumed a locked position the nut 9 may be tightened up, that is to say, turned to pull the stud 8 to the left as viewed in Figure 3, with the result that the toggle is more positively urged to its locked position and the clamping action of the ring 5 increased.
