DRUM LOCK Filed June 5, 1935 3 Sheets-Sheet 5 F lNVENTOR-' Fig.]a- BY Patented Dec. 8, 1936 UNlTED STATES PATENT OFFIE Claims.

The object of this invention is toprovide a lock for drums or containers of liquids that are .exposed to tampering with by unauthorized persons or theft of their contents.

5 Local laws in many places forbid keeping drums for alcohol inside of buildings. When stored outside, mischievous persons often turn the faucets and allow the contents to waste. Still more frequently, thieves open the'faucets and: steal the contents.

This invention consists of a strong, simple, compact, effective, and cheap lock to'overcome such conditions and, also, a device-for that purpose that is easy to understand and operate and one which can be quickly applied and removed.

Its use is not limited to containers of liquids, if the construction of the container bears a projection for its attachment like the faucet herein shown.

In the accompanying drawings, in which like numbers of reference denote like parts wherever they occur,

Fig. 1 is a side elevation of a drum, with the lock in position thereon.

Fig. 2 is an end elevation of a modified form of drum, with the lock in place.

Fig. 3 is a side elevation of the main locking device.

Fig. 4 is an elevation thereof, showing the part that faces the end of the drum.

Fig. 5 is a plan view of the subject-matter of Figs. 3 and 4, looking downward in the said views of the drawings.

Fig. 6 is a fragmentary view of the subjectmatter of Fig. 4, showing the cap of the drum with the top part of the locking device and padlock in place.

Fig. 7 shows a modification of the hood of the lock in position, covering the faucet, and a fragmentary view of the drum.

Fig. 8 is a side elevation of one part of the lock when the drum is provided with a bunghole in the side of the drum in addition to one in the end.

Fig. 9 is a plan view of the same.

Fig. 10 shows a modification of the locking device, to be used on drums where the faucet is in the end of the drum and there is only one bunghole, located in the side of the drum.

Fig. 11 is a plan view of the same.

Fig. 12 is a fragmentary view of part of the device of Fig. 11, showing how the bars may be adjusted for variation in the position of the bunghole.

Fig. 13 is a plan view of the bunghole cap.

Fig. 14 is an enlarged side elevation of the same.

Fig. 15 is a side elevation of another form of cap.

In Fig. l, the drum I is provided with an opening or bunghole 2 in its end and another opening or bunghole 3 in its side. A cap i closes opening 2, and cap 5 plugs opening 3. Each of the said caps and holes is threaded.

Faucet 6 is threaded at l and screwed into opening .8 in the end of drum 5. Hood 9 is adapted to inclose faucet ii and is made of metal to protect faucet 6 from being opened. Hood 9 is borne by bar iii, which is securely fastened to its side or bottom that faces the end of drum I. Brace H additionally secures hood or housing 9 to bar it. Bar it is notched at l2, so as to'provide afork thatfits around faucet 6. The other end of bar it bears projection l3, preferably made integral therewith, containing a notch E i, adapted to receive an angle of the polygonal cap or nut 4, from which projects a lug 115, containing an eye It, through which may be passed the hasp ll of a padlock l8, to lock the hood 9 over faucet 6 when the parts are in the positions shown in Figs. 6 and 7. Notch Hi prevents the rotation of cap 4. Likewise, if, on account of expansion or contraction, due to heat or cold, the fit of an angle of cap .4 into notch ii is not tight, the flat side edge 5 I 9 may fit tightly against the straight front edge 28 of projection l3, equally preventing rotation of cap The drawings show cap 4 as a hexagonal nut, but it may be quadrilateral or otherwise polygonal. these other shapes of nuts will hold the same from rotation in the same way as above explained with regard to the hexagonal form.

The notched corner 2! in the hood 9' and the flange orprojection 22 on "drumi in Fig. 7 illustrate a modification of construction from that illustrated in Fig. 3. The countersink 23 in Fig. 2 shows a differenceinsconstructionof drum I from that shown in Fig. '7.

The lock for opening 3 (when there is such an opening in the side of the drum i, as shown in Fig. 1) may be combined with the lock for faucet 6 and opening 2, as hereinbefore described, as illustrated in Fig. l, in which the bar 2 3 is provided with an arm 25 at substantially a right-angle thereto, containing an eye 25, adapted to fit over lug l5 and to be looked thereon by the padlock I8 in the same manner and at the same time as bar Ill.

The other end of bar 24 is preferably pro- The fiat sides or corners of vided with a pair of ears 21, depending from the branches 28 of a fork. The said fork fits around shank 29 of the form of cap shown in Figure 15 and is held in place thereon by head 36, while the ears 2? fit alongside two opposite fiat sides 3! of the polygonal nut or cap 5.

One difference between the bar 24 shown in Figs. 1, 8, and 9 and the construction appearing in Figs. 10 and 11 is the provision of the hinge 33 between the analog of the bar 2 1 and the bar Ill. This unites in one device the locking members for both the faucet 6 and the opening 3 in the side of the drum.

The location of the opening 3 is not uniform in all drums containing an opening in the side, some being nearer and others farther from the end where the faucet 6 is located. This difference in construction can be accommodated by adjusting the straps and 35 by sliding the same relative to each other, the rivets 3i being inserted in the holes 38 that will make the most accurate adjustment and hold it. The

straps

34 and 35 take the place of the bar The lug E5 on cap 4 passes through an eye 32 in bar it], as shown in Figs. 1, 2, and 6.

The eye it in strap 35 as shown in Fig. 11 serves the same purpose in this modification as eye 32 shown in Figs. 3 and 4.

The bar 38 shown in Figs. 10 and 11 is securely fastened to bar it and, by contacting the projection 22 of drum i, prevents bar In and strap from being moved from side to side.

When the lock is to be applied, the hood or housing 9 is fitted over faucet 6, and the fork formed by notch l2 slipped around faucet 6. and the bar iii moved as far toward the faucet 6 as possible, making it possible for lug l5 to pass through the eye 32 in bar E8. The hasp I"! of the padlock it can then be inserted through the eye H3 in lug 55. If an opening 3 in the side of the drum l is also to be locked, the bar 241 and the arm 25 will have been put in position for that purpose, with lug l5 passing through eye 26 before the padlock is slipped through eye it. When the device of Figs. 9 and 10 is used, the mode of attachment will be similar, that is to say, the fork formed by notch [2 will be pressed closely against the faucet 6 before the bar 25 of that device is fitted to lock the hole 3 in the side of the drum.

It will be obvious that many minor changes may be made in the form and arrangement of the several parts of this device without departing from the spirit of this invention or the scope of the following claims.

Having thus described this invention, what is claimed and desired to be secured by Letters- Patent is:
