BUNG-BUSHING.
Specification of Letters Patent.
Patented May 26, 1908.
Application filed April 13, 1906. Serial No. 311,573.
To all whom it may concern.'
Be it known that I, THOMAS PENDERGAST, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Bung- Bushings; and I do hereby declare the fo lowing to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.
This invention is an improved tapping bush having a twofold purpose and advantage. First, it affords means for a positive internal engagementby a corrugated wrench or turning tool for screwing the bush in and out of its place in the barrel-head. Second, it provides an annular cutting edge beneath the cup-shaped wooden bung or plu so that the central web of the bung can easigly be cut from its tubular body and driven into the barrel.
In the accompanyin drawings, which form a part of this speci cation: Figure 1 is a sectional erspective view of the bung, shown exteriorly threaded and screwed into a fragment of the head of a barrel. Fig. 2 is a central vertical section of the bush with its wooden bung or plug in place. Fig. 3 is a similar section showing the web of the bung as it is being cut from its tubular body and driven down into the barrel. Fig. 4 is a top plan view of the bush.
The metal bush a has at its lower end an internal scalloped llange b, of substantial thickness, desirably about a quarter of an inch. This scalloped flange b is designed to receive the counterformed body of a wrench or turning tool (not shown) by which means the tool can firmly grip the bush interiorly for screwin or unscrewing it, without slipping and without scarring or mutilating the metal, the en agement being continuous around the scaglloped flange. Thisfeature overcomes a common objection to the ordinary styles of tapping bushes having bottom flanges with opposite notches for engagement by the lugs or keys of the wrench, and which are ofttimes scarred or mutilated when the bush offers resistance to .turning under action of the tool. The said flange b is further constructed with an annular 'cutting edge c vbungs having on its upper surface, which edge may extend aroundv the bases of the scallops, the flange I being downwardly beveled around such cutting edge c. Thus the cutting edge is presented to the bottom of the cup-shaped wooden plug or bung d, shown in Fig. 2 seated on the flange and having its top edge swelled into the annular groove e in the bush. By this means, when it is desired to drive in the frangible web j' of the bung, for the pur ose of inserting the spigot or faucet to tap t e barrel, this can be done easily by driving down this central Web j' against said cutting edge c, as shown in Fig. 3, thus cuttin the web from the remaining tubular body of the bung and force it into the barrel. At the same time, liability of improperly breaking the web or of splitting the same, or splitting the remaining tubular part 'of the bung, is avoided, and such tubu ar portion of the bung is secure in its place since it is supported by the flange b, also, by virtue of this construction, it is unnecessary to employ the usual cylindrical kerfs either above or beneath the frangible web f, for the purpose of facilitating the driving 1n of the web, because this is made an easymatter by the annular cutting edge c. Hence one. operation may be saved in the manufacture of the wooden bung.
Havingthus fully described my invention, what I- claim as new and desire to secure by Letters Patent ofthe United States is:
1. A bung bushing having at its lower end an internal flange provided with a raised annular cutting edge, in combination with a cup-shaped wooden bung fitted in said bushing, whereby the central web of said bung can be out from its tubular body portion and driven down into the barrel.
2. A metallic bung-bushing having at its lower or inner end an internal scalloped flange with a beveled upper surface terminatingin a raised inner marginal cutting edge, substantially as and for the purposes described.
In testimony whereof I affix my signature, in presence of two witnesses.
THOMAS PENDERGAST.
