8 Claims.

The present invention relates generally to can openers, and more particularly to a cabinet can opener.

Can openers are practically indispensable in the modern kitchen. Moreover, the frequency of use in most kitchens is such as to require their availability for substantially instant use if unnecessary inconvenience and annoyance are to be avoided. Although this requirement of availability for immediate use has long since been overcome by the development of can openers adapted to wall attachment, the construction, being primarily functional, has left much to be desired in aesthetic appeal.

It is, therefore, an object of the present invention to provide a styled cabinet for a wall type can opener, said cabinet to encloseand conceal substantially all of the can opening mechanism while not in use.

Another object of the invention is to provide a can opener cabinet that, during intervals of nonuse, will afiord protection from dust and dirt for all parts of the can opener that might come in contact with food during use.

Another object of the invention is to provide a can opener cabinet which is an integral part of the can opener construction, thus to simplify the action of alternately using and storing the can opener. I

Another object of the invention is to provide a can opener cabinet integral with a wall type can opener so arranged as to permit instant use and subsequent instant storage of the can opener.

Another object of the invention is to provide a can opener housing integral with a wall type can opener, the housing being of molded plastic material and all structural and load-bearing elements being of metal. I Another object of the invention is to provide a cabinet model can opener constructed so that the act of opening the door of the cabinet simultaneously positions and locks the can opener for use.

Another object of the invention is to provide, in combination, ,a can opener and a can opener cabinet having the advantages enumerated above.

-Another object of the invention is to provide,

in combination, a can opener and a can opener cabinet adaptable to mountable and demountable attachment as a unit to a wall. These and numerous other objects and advantages will become evident in the following descriptive delineation of construction and operation of the device.

Referring to the drawings more particularly by reference numerals, 26 indicates a metal backplate providing the principal structural support for the can opener cabinet and providing, in addition, means such as the angular deformities 2| for demountable attachment to a trapezoidal wall plate (not I shown). A styled housing, shown generally as 22, preferably of molded plastic material, includes an outer shell'23, an inturned inner flange 24 extending continuously around the front opening except for the hinge end, thereby forming a door jamb, an acute angled flange 25 extending across the hinge end, and buttresses 2'6 at the corners and at points intermediate along the upper and lower sides of the shell and on the inside thereof. A liner 21, preferably of molded plastic material, may be assembled within the housing 22 to improve the appearance of the interior of the cabinet. This liner 2! is shaped like an open rectangular box with one end removed and has a beaded front edge 28 rabbeted to join smoothly and evenly with the housing flange 24. The liner 2'! is retained in place by the flange 24 and the back plate 28, the latter being secured to the buttresses 26 by means of screws 38. Lengthwise movement of the liner 21 is additionally restrained by abut, ment of the beaded edge 28 against the buttresses 26. Attachment of the backplate 28 to the .but-, tresses 26 enables the housing shell 23 to extend rearwardly beyond the backplate so as to permit substantially flush abutment of the shell 23 with a kitchen wall (not shown), except for a portion of the rear edge of the shell which is cut back as shown at 29 to allow mounting engagement of the backplate deformitites 2| with a trapezoidal wall plate (not shown) as aforementioned.

A hinge bracket secured to the backplate 28 as by spot welding has an upper flange 36 and a lower flange 31, each flange having a hole 38 vertically aligned one to the other for insertion of a hinge pin 39 having near the upper end thereof deformities 58 for retention in said holes. In addition, the lower flange 31 has attached thereto, as by a pivot pin 48, a trigger release 4| rotatable in a plane parallel to the flange and about the pivot pin 48, being limited in its rotative motion, however, by a lock pin 42 secured, as by riveting, to the trigger release 4| and by projecting upward therefrom through a slot 43 in said lower flange 37. The trigger release 4| includes a plate 44 disposed horizontally against the lower face of the flange 31, through which plate passes the pivot pin 48 and to which plate is riveted the lock pin 42 and a depending L- shaped trigger 45 which extends through and below an open ended slot 46 in the lower part of the housing shell 23 to permit manual rotation of the trigger release within the limits imposed. The trigger release 4| is continuously urged in its limited rotative motion in a direction generally toward the hinge pin by the action of a tension spring 4'! attached at its one end to a deformity 48 depending from the plate 44 and at its other end to a deformity 49 depending from the flange 31.

A door assembly shown generally as is rotatably retained by the hinge pin 39 and includes as its principal structural member a door plate 56 having an upper flange 51 and a lower flange 58, each flange having a hole 59 vertically aligned one to the other through which holes the hinge pin 39 passes. In addition, the lower flange has a portion of its edge shaped to form a circular are 80, said are having its center on the axis of the hole 59 in said lower flange. The are 68 terminates at its one end in a detention notch BI and at its other end in a locking notch 82. A styled door 63, preferably of molded plastic material, is formed as an open shallow rectangular box except for the hinge end 64 which is extended beyond the open face 65 of the box, the long sides 66 of the box being also continued as flanges 61 to the extended end and terminating therebeyond. Gussets 68 lend structural support to the hinge end 64 and buttresses 69 at the cor.- ners of the swinging end and at points along the long sides 68 near the hinge end serve to attach the door to the ,door plate by means of roundhead screws 18 and countersunk screws II. The door gated opening or slot 16. Additionally, the door .plate56 has a hole 1'! as shown in Fig. 10 and a hole 18 as shown in Fig. 11 for respective purposes to appear. A body 19 is secured to the boss "15, as "by rivets 88, and has an impressed boss 8| of elongated shape and containing an irregular opening 32 in the shape of a round hole with a slot extending horizontally therefrom. Additiona'lly, the body 19 has an impressed circular boss 83 containing a hole 84, as shown in Fig. 11, a .subtended circular boss 85, a can engaging flange .88, and a hole 81 formed through a flan e 88, the flange 88 being formed from the parent metal of the body by a deforming operation. The hole 81 has a bushing 89 pressed therein, the bushing being further secured by a turned back shoulder 98. The bushing 89 extends also through the hole H in the plate 56 and the hole 12 in the door 63 and contains a shaft 9| uponone end of which is mounted a crank shown generally as 92. The crank 92 includes a formed arm 93 and a roller type handle 94 attached to the free end of the arm 93 by means :of a pin 95. The pivot end of the arm 93 is secured to the shaft 9| by pressing thereon, At the other end of the shaft 9| is mounted a cup washer .96 which abuts a shoulder 91 on the shaft 9|, a gear .98, a flat washer 99, and a feed wheel I88, the latter being internally threaded for attachment to a reduced threaded portion of the shaft 91 and thus retaining all members mounted at this end of the shaft against the shoulder 91. A conical compression spring |8I bears at one end against the end of the bushing 89 and at the other end against a bearing plate I82 contiguous to the arm 93 and thus continuously urges the shaft 9| and all elements assembled thereon to the ri ht as shown in Fig. 10 until the cup washer 96 bears continuously against the end of the bushing 89. It is obvious that rotation of the crank 92 will cause rotation of the shaft 9| and all elements assembled thereon including the gear 98 and the feed wheel |88, the latter of which has a milled or serrated edge adapted to be disposed under the rim of a can to be opened.

A carrier I slidably engages the bosses 8|, 83 an 85 f t body 9 and i idably attached to the body at one end by the engagement of a pin I86 in the slotted portion of the opening 82 in the boss 8|, as shown in Fig. 12. The other end of the carrier I85 is pivotally mounted on the perimeter of a disc I81 supported in the hole 84 contained in the boss 83 of the body 19. The disc I81 is rotated by a handle I88 to which it is secured, as by rivets I89. The handle "18 with the attached disc I8! is pivotally mounted to the carrier I85 by means of a pin I|8, said pin being disposed eccentrically with respect to the center of the disc I81 and extending through the hole 18 in the door plate 56, said hole being suinciently large as to clear the pin and associated members as the handle I88 is rotated. The head end of the pin |I8 mounts a can engaging deflegtor bracket II I on the face of the carrier 185, the pin being pressed into the latter two members and retained at its other end by the action of a compression spring II 2 acting between the handle I08 and a cup-shaped spring washer II3 retained by a slotted washer II 4as shown in Fig. 11. The spring II2 thus causes the carrier to be urged against the bosses 03 and 05 of the body I9, as shown in Fig. 11, but at the same time p rmits this end of the carrier to be separated from the body 79 by the application of a force sufficient to overcome the spring action.

The carrier I05 has an outwardly stamped bulge I20, upon which is mounted a stud shaft I2I having grease grooves I22 and at its outer end a reduced threaded portion I23, said stud shaft being disposed in a downwardly inclined direction due to the shape of the bulge I20. A hub I24, having a cutting disc I25 is rotatably mounted on the stud shaft I2I and is retained thereon by a nut I20 having a frusto-conical body I21 adapted to fit within a similarly shaped recess in the hub and to abut a shoulder I28 on the stud shaft I2I, as shown in Fig. 10. A gear I29 is mounted on the hub I24, being in driving engagement therewith by means of matching flats on the periphery of the hub and on the hole of the gear, but at the same time beingcapable of some angular movement relative thereto due to the loose engagement of the flats. The gear abuts a flange I30 on the hub I24 and a conical compression spring I3I acts against the gear so as to urge said gear and the hub I24 towards the outer end of the stud shaft I2I, but permitting axial movement of the gear I29 on the hub I24.

The carrier I05 also has a ledge I adapted to overlie a can.

Operation With the device mounted flush against a wall as aforementioned, the door assembly 55 with its attached can opening mechanism is retained in its closed position by the engagement of the lock pin 42 with the detention notch 6|. When it is desired to use the can opener, it is only necessary to grasp the crank 92 and swing the door open to a position at right angles to the cabinet which will cause the lock pin 42 to engage with the locking notch 52 and thus to hold the door firmly in open position. When it is desired subsequently to close the door, the lock pin 42 is disengaged from the locking notch 02 by rotating the trigger against the action of the spring 41 which, due to the rotating movement of the locking pin against the side of the locking notch, causes the locking pin to move the door so that the locking pin will rest at the locking notch end of the circular are 60, from which position the door may be swung to its closed position with the same hand used to operate the trigger.

To open a can, the door assembly 55 is placed in open position and the handle I08 is rotated forwardly to the position of Fig. 9. The latter motion, by virtue of the eccentric attachment of the carrier I05 to the disc I01, lifts the outer end of the carrier causing separation of the gear I29 from the gear 98 and also separation of the cutting disc I25 from the feed wheel I00. Thereupon, the rim of a can may be inserted in the space between the cutting disc I25 and the feed wheel I00 so that the rim overlies the feed wheel I00 and the side of the can rests against the edge of the flange 80. The handle I08 is then rotated to its closed position during which process the carrier I05 is lowered and the cutting disc I25 is forced downward to penetrate the lid of the can "just inside the rim. The action of the spring II2, while permitting sufiicient lateral movement of the carrier I05 to provide space for the wall of the can between the side of the feed wheel I00 and the sideof the cutting disc I25, at the same time resists such movement and causes the cutting disc I25 to bear against the inside of the rim of the can. The lid is therefore sheared just inside the rim and the inside of the rim is at the same time pressed and folded neatly and smoothly against the inside of the wall of the can.

The lowering of the carrier I 05 also permits the deflector bracket III to engage, and the ledge I35 to overlie, the rim of the can so that the can is held and supported firmly in a vertical position. It will be noted that, during its taneous rotation of the cutting disc I25 and the feed wheel I00 at relative speeds determined by the gear ratio. As the crank 92 is rotated, the rotating feed wheel I00 will cause the can to turn on its own axis thus feeding the lid against the rotating cutting disc I25, thereby shearing the lid and smoothing the rim.

When the lid has been partially or completely severed as desired, the can may be released by again lifting the carrier I05. The handle I08 may then be rotated to its closed position and the cabinet door assembly 55 may be closed as above described.

Manifestly, the can opener mechanism and the plastic housing are so related that the entire structural load and operating load are carried by the former and the bracket unit, the plastic elements being carried rather than serving as a support. It is also clear that opening of the door simultaneously positions the can openingmechanism for use and effects locking in place.

It is clear that there has been provided a cabinet can opener which fulfills the objects and advantages sought therefor.

It-is to be understood that the foregoing description and the accompanying drawings have been given by way of illustration and example. Itis also to be understood that changes in form of the elements, rearrangement of parts, and substitution of equivalent elements, which will be obvious to those skilled in the art, are contemplated as within the scope of the present invention which is limited only by the claims which follow.
