CASK-HEAD CLOSURE.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed February 25, 1905. Serial No. 247,394.

To all whom it imzy concern;

Be it known that I, CARL WELLHoFER, Sr., a citizen of Germany, residing at Heidingsfeld, near Wiirzburg, Bavaria, Germany, have invented certain new and useful Improvements in Cask-Head Closures; and I do here by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention consists of an im proved cask-head closure, as hereinafter set forth and particularly pointed out in the claims.

In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is a section through the head of a cask, showing the form of closure hitherto in use, the section being taken longitudinally of the closure-bar. Fig. 2 is a section taken at right angles to that of Fig. 1, showing the damage to the head-staves liable with the kind of closure illustrated in Fig. 1. Fig. 3 is a section through the cask-head, showing one embodiment of the present invention, and Fig. 4 is a part plan view of Fig. 3. Fig.- 5 is a part vertical section through the caskhead, showing a modified form of the invention. Fig. 6 is a plan view of the closure-bar and the feet for supporting the same. Fig. 7 is a part vertical section of a further modification, and Fig. 8 a plan of the bar. Fig. 9 shows a furtherv embodiment in vertical section, and Fig. 10 an end view of Fig. 9.

In casks having the heads curvedinwardly, as shown at Fig. 1, or otherwise not forming a plane surface the lever-bar for tightening up the door e has usually been made as shown in Fig. 1, and consequently when the door is tightened up the stave of the head is liable to break away, as illustrated in Fig. 2, at the inclined portion close to the joint with the sidewall staves.

According to the present invention the feet against which the resser-bar works are so connected to the latter that they will adjust themselves to the surface of the staves against which they press, and thus prevent the breakage of the latter at the point mentioned.

In the embodiment illustrated in Figs. 3

and 4 the door e, with its screw-spindle eand nut, is attached and tightened onto the caskhead by means of the cross-bar a, pivoted at c c to the feet I) b, which rest on the headstaves t t. Owing to this arrangement the feet will accommodate themselves to the bend of the staves, and breakage of the latter will be avoided.

In Figs. 5 and 6 the same result is attained by providing the feet I) b with rounded heads, on which the ends of the presser-bar a rest and against which they may be secured, by means of screw-studs c, with nuts, so that in this case also the feet will accommodate themselves to the bend of the caskhead. The studs 0 are arranged in corresponding slots of the bar a as shown at Fig. 6.

In Figs. 7 and 8 the desired result is attained by curving the ends of the bar a so that the studs 0 of the feet 6 will always be at right angles to the latter whatever may be the curve of the cask-head.

As shown, the closure is suited to a caskheadof a definite curve. To adapt it for use changeably on different curvatures, the barapertures might be elongated to form slots, as in Fig. 6.

In Figs. 9 and 10 the bar a is U-sl1aped in cross-section, and the feet 6 are pivoted between the webs of the same, as at 0 the result being the same.

Obviously the invention is also available in securing bungs or closures in the curved sides of casks or in other positions where the wall does not form a level plane surface.

' I claim as my invention- 1. The combination, with a cask and a closure therefor, of feet arranged to rest upon the caskat both sides of the opening, a bar spanning the opening and connecting the feet, and means for attaching the closure to the bar at a point between the feet. 7

2. The combination, with a cask and a closure therefor, of feet arranged to rest upon the cask at both sides of the opening, a bar spanning the opening and movably connected at its ends to the feet, and tension-applying means for attaching the closure to the bar at a point between the feet.

3. The combination, with a cask and a closure therefor, of feet arranged to rest upon the cask at both sides of the opening, a bar spanning the opening and movably connected at its ends to the feet, a stud secured to the closure and passing through an aperture in the bar, and a nut threaded upon the end of the stud.

4. The combination, with a cask and a closure therefor, of feet arranged to rest upon the cask at both sides of the opening, an arched bar spanning the opening and pivotally connecting the feet, a stud secured to the closure and passing through a hole in the bar between the feet, and a nut threaded upon the end of the stud.

5. The combination, with a cask and a closure therefor, of feet having a broad bearhole in the bar between its two ends, and a 20 nut threaded upon the end of the stud.

In testnnony whereof I hereunto afliX my signature in the presence of two witnesses.
