This invention relates to a can opener and more particularly to a fixedlymounted can opener in which a can is inserted and opened by movement of the can.

.An object of this invention is to provide a can opener in which a metal can may have the top perforated by sliding the can inwardly relative to the supporting base.

Another object of this invention is to provide a can opener having a pivoted perforating member on a base which is actuated by a sliding movement of a can supporting member.

A further object of this invention is to facilitate the perforation of sealed cans of liquid contents.

A still further object of this invention is to provide a can opener wherein the can is at all times maintained in a vertical position to avoid spilling of the contents upon opening thereof.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operat on as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the can opener forming the subject of this invention;

Figure 2 is a top view of the preferred form of the present invention;

Figure 3 is a vertical sectional view of the preferred form of the present invention showing the can puncturing plate in raised position;

Figure 4 is a vertical sectional view similar to Figure 3 with the can puncturing plate shown in its lowered position; and

Figure 5 is a sectional view taken substantially along the section line 55 of Figure 2.

Referring now more specifically to the accompanying drawings, it will be seen that the im proved can opener forming the subject of this invention includes, as shown in Figure 1, a mounting bracket H) which is adapted to be fiXedly se cured to a vertical support and a can support I 2.

The bracket in is provided with a first pair of rails Hi extending perpendicular thereto. The rails M are formed of a U-shaped channel mem her with the openings IS in the rails I l facing toward one another. The other ends of the rails are sealed as at l8. Suitable braces 22 are mounted between the rails It and the bracket ID rigidly securing the rails in position.

A second pair of rails 22 are mounted on the bracket above the rails M. The rails 22 are rigidly held in position by braces 2d. The rails 22 are formed of U-shaped channel members having openings 25 therein facing each other. The outer ends of the rails 22 are jo d o e and sealed by a plate 28. Rails 22 extend at an angle downwardly from the brackets [0 toward the rails 15.

The can support l2 comprises a bottom plate 32 upon which a can 32 will rest and an upwardly extending wall 34. Wall '34 is shaped to conform with the contour of the wall of a can 32 when the can is placed in position on the support. A pair of rollers 35 are mounted on the wall 34 at diametrically opposite points near the top of the wall. The rollers 36 are mounted in the openings it in the rails l4 and permit the can support to be moved toward and away from the bracket ID.

A vertically extending longitudinal member 38 is secured to the rear of wall 34 adjacent the midpoint thereof. The member 38 extends above the wall 35 and is provided with a bifurcated end 4!]. A link 42 is pivotally secured at its midpoint to member 38 at the bifurcated end 62 thereof.

, A can puncturing plate 44 having a pair of ears 46 secured to the top thereof at the center is pivotally mounted on one end of the link 42 by means of a pin 48 extending through th ears 46 and the link 42. The lower surface of the can puncturing plate 44 is provided with a pair of sharp projections 50 at diametrically opposite points thereon.

A pair of rollers 52 are mounted on opposite sides of the other end of link 2. The rollers 52 are received in the openings 26- in the rails 22.

In practical use, a can is mounted on the support l2 and thecan and the support are moved in a direction toward the bracket It. As the support I2 moves rearwardly link 42 will b caused to move about the pivotal connection to the support 12 thereby causing the projections 52 to puncture the top of the can. The plate 64 is urged downwardly due to the rollers 52 riding up along the rails 22. After the can has been punctured movement of the support 12 and the can away from the bracket will cause the plate 44 to be raised thereby allowing easy removal of the can from the support. The

rollers

36 and 52 will be prevented from separating from the rails it and 22 by means of the

members

18 and 28 respectively.

From the foregoing, the construction and op eration of the device will be readil understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.

What is claimed as new is as follows:

1. A can opener comprising a bracket adapted to b secured to a vertical support, a first pair of parallel rails secured to said bracket and extending perpendicular thereto, a can support mounted for sliding movement on said first rails, a second pair of rails secured to said bracket above the first pair of rails, a can puncturing plate, means for connecting said can puncturing plate to said can support and said second pair of rails.

2. A can opener comprising a bracket adapted to be secured to a vertical support, a first pair of parallel rails secured to said bracket and extending perpendicular thereto, a can support mounted for sliding movement on said first rails, a second pair of rails secured to said bracket above the first pair of rails, a can puncturing plate, means for connecting said can puncturing plate to said can support and said second pair of rails, said can support having a pair of rollers extending outwardly from the sides thereof at diametrically opposite points, said first rails comprising a pair of channel members having their openings facin toward each other, said rollers being received in the openings in the channel members.

3. A can opener comprising a bracket adapted to be secured to a vertical support, a first pair of parallel rails secured to said bracket and extending perpendicular thereto, a can support mounted for sliding movement on said first rails, a second pair of rails secured to said bracket above the first pair of rails, a can puncturing plate, means for connecting said can puncturing plate to said can support and said second pair of rails, said can support having a pair of rollers extending outwardly from the sides thereof at diametrically opposite points, said first rails comprising a pair of channel members having their openings facing toward each other, said rollers being received in the openings in the channel members, said second pair of rails being comprised of channel members having openings therein facing each other, said second rails extending downwardly at an angle from the bracket toward the first pair of rails.

4. The combination of claim 3 wherein said means for connecting the can puncturing plate to the can support and the second pair of rails comprises a link pivotally secured adjacent its midpoint to the top of the can support, said can puncturing plate being pivotally secured to one end of said link and a pair of rollers mounted on opposite sides of the other end of said link, said rollers being received in the openings in the channels of the second pair of rails.

5. The combination of claim 4 wherein said can puncturing plate is provided With a pair of downwardly extending projections at diametrically opposite points.
