3 Chime.

The present invention relates tonew and useful improvements in openers particularly for milk cans and hasfor one of its important objects to provide, in a manner as hereinafter set forth, a device of this character which, after a can has been opened, is adapted to be secured thereon to facilitate the dispensing or pouring of the milk.

Another very important object of the invention is to provide a can opener of the aforementioned character embodying a novel construction and arrangement through the medium of which the device is adapted to accommodate different sizes of cans.

Other objects of the invention are to provide a can opener oi the character described which will be comparatively simple in construction, strong, durable, highly emcient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation of an opener constructed in accordance with the present invention, showing same mounted on a can.

Figure 2 is aview in top plan thereof.

Figure 3 is a view substantially similar to Fig. 1 but showing the can in vertical section.

Figure 4 is a cross sectional view through the invention, taken substantially on the line t-d of Fig. 3.

Figure 5 is a detail view in bottom plan of the pouring punch.

Figure 6 is a fragmentary view in vertical longitudinal section through the intermediate portion of the device which includes the vent punch.

Referring now to the drawings in detail, it will be seen that the'embodiment of the invention which has been illustrated comprises a metallic bar i which terminates, at one end, in a depending hook 2 which is engageable under the. rim 3 of a conventional milk can t, as illustrated to advantage in Fig. 3 of the drawings. At its other end, the bar i terminates in an integral, inclined handle 5. v

Fixed in the bar i and extending therethrough, adjacent the hook 2, is a forwardly inclined pouring spout 6. The pouring spout 6 is in the form of a tube and terminates atone end in a i substantially bevelled, tubular punch I which is adapted to penetrate the top 8 of the can 4. Fixed on the punch 'l in spaced relation below the bar I is a disk 9 having mounted therebeneath a gasket l engageable on the can top 8 for preventing leakage around said punch i.

Also fixed in the bar i at a longitudinally spaced point from the pouring spout 6 is a tubular vent punch Ii. The ventpunch ii is provided with a substantially bevelled free end l2 which is adapted to be readily driven through the top 8 of the can 4. As best seen in Fig. 6 of the drawings, the vent punch ii is fixed in an opening which is provided therefore in the metallic bar i.

Mounted for longitudinal sliding movement on the metallic bar i is a metallic loop i3. Depending from the slidable loop I3 is a hook Hi which is engageable under the rim 3 of the can to coact with the hook 2 for securing the device in position on said can. A coil spring l5 has one end anchored to the metallic bar I and its other end secured to the loop l3 for yieldingly pulling the hook M toward the stationary hook 2.

It is thought that the manner of using the device will be readily apparent from a consideration of the foregoing. The hook 2 on the forward end of the metallic bar i is first engaged under the rim 3 of the can 6 with the point of the pouring prong i resting on the top 8 of said can. Downward pressure is then exerted on the bar i in a manner to cause first'the pouring punch i and then the vent punch ii to be driven through the can top 8, in the manner clearly shown in Fig. 3 of the drawings. The hook It is then engaged beneath the rim 3 of the can where it is held by the spring l5 and, with the gasket i6 engaged on the top 8 around the opening which has been formed by the pouring punch l, the milk is ready to be poured.

It is believed that the many advantages of a can opener constructed in accordance with the present invention will be readily understood and although a preferred embodiment of the device is as illustrated and described, it is to be under stood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:-

1. A can opener comprising a metallic bar, a hook on one end of said bar engageable under the rim of a can, a handle on the other end of the bar, a substantially tubular pouring spout extending through the bar adjacent the hook and fixed therein, said pouring spout terminating in a. substantially bevelled end constituting a pouring prong adapted to penetrate the top or the can, a disk fixed on the pouring punch in spaced'relatlon beneath the bar, a gasket mounted beneath said disk for engagement with the top of the can for preventing leakage around the pouring punch, a substantially tubular vent punch fixed on the bar in spaced relation to the pouring punch and adapted to penetrate the top of the can, and a hook slidably mounted on the bar and. engageable beneath the rim oi. the cani'or coaction withthe first named hook for securing the bar thereon.

2. 'A can opener comprising a. bar, a stationary hook on one end of the bar engageable beneath the rim of a can, a substantially tubular pouring punch fixed in the bar adjacent the hooks a substantially tubular vent punch fixed in the bar in spaced relation to the pouring punch, a loop slidable on the bar, a hook depending from said loop and engageable beneath the rim of the can for coaction with the first named hook for securing the bar in position thereon, and a coil spring having one end anchored to the bar and its other end secured to the loop for yieldingly urging the second named hook into engagement with the can.

3. A can opener comprising a metallic Bar, a depending hook on one'end of the bar engageable beneath the rim of a can, an angularly projecting handle integral with theother end of the bar, a forwardly inclined pouring spout extending through the bar and fixed therein adjacent the hook, said pouring spout terminating, at one end,

in a substantially bevelled pouring punch adapted named hook for securing the bar in position on said can, and a coil spring having one end anchored to the bar and its other end secured to the loop for yieldingly urging the second named hook into engagement with the can.
