Definitions
- Ci. nit-'52 I This invention relates to can openers of the type used for removing a sealing strip extending about a can of the vacuum sealed type.
- Openers which are usually employed for opening such cans consist of a key having a shank provided adjacent one end with a slot or eye in which a free end of a sealing strip is fitted, the other end of the shank carrying a cross head or the like by means of which the key is turned in order to wrap the strip about the shank and progressively tear the strip loose from the can and its cover until the strip is entirely removed and the cover released for removal from the can.
- Such can openers are not entirely satisfactory as the strip has a tendency to wind unevenly about the shank of the key instead of forming an even compact coil and in addition it is di-fiicult to remove the coiled strip from the key after it has been entirely torn loose from the can and the cover. Therefore, the key is usually thrown away with the strip wrapped about it, thus avoiding the trouble of unwrapping the strip from the key and also eliminating likelihood of the strip cutting a persons fingers while unwrapping it from the key.
- one "object of the invention is to provide a can opener including a key adapted for detachable engagement with an end of a can-sealing strip and rotatably mounted through the shank of a yoke which guides wrapping movement of the strip about the key into a tight coil and prevents portions of the strip from slipping transversely off of the coil as it is torn loose from the can and wrapped about the key.
- Another object of the invention is to provide a can opener of such construction that a sealing strip may be easily and accurately wrapped in a coil about a key but allow the strip to be readily removed from the key in its coiled condition and thus eliminate unwinding of the strip from the key in order to remove it.
- Another object of the invention is to provide a can opener of this type wherein a portion of the key is slidable longitudinally as well as being rotatable relative to the yoke, the said key being formed with a strip securing slot which is open at its front end so that a coiled strip may be shifted along the key and otf at the front end thereof when removing the coiled strip from about the key.
- Another object of the invention is to so mount the key that while its longitudinal movement will normally be limited it may be entirely removed when repairs or a thorough cleaning are necessary.

- the sleeve or shank 4 consists of a metal tube formed with a bore 5 which extends its full length and is open at both ends.
- a cross head 6 extends across the front end of the sleeve or tube 4 and at its ends this cross head carries arms 7 which are of such length that when the device is applied to a can the arms will extend across the sealing strip 1.
- a key 8 which is formed of stilt metal extends through the bore of the sleeve 4 and is of such length that it may protrude from front and rear ends of the bore.
- a portion 9 of the key is of reduced thickness thus providing the key with circumferentially extending abutment shoulders 10 and 11, at front and rear ends of the reduced portion 9.
- a set screw 12 is screwed into a threaded opening 13 formed through a side portion of the sleeve and is of such length that it may extend into the bore of the sleeve and constitute a stop for engaging the shoulders 19 and 11 and thus limiting sliding movement of the key when moved from the extended position for use shown in Fig. 3 t0 the retracted position shown in Fig. 4.
- the reduced portion 9 of the key is circular in cross section allows the key to be turned in the sleeve as well as slid longitudinally through the sleeve when the sleeve is grasped by the head or handle 14 which has been shown substantially triangular and is formed by bending the metal rod from which the key is formed so that it extends diagonally from the key as shown at 15 and then transversely towards the other side of the key as shown at 16 and then forwardly at an inward incline toward the key as shown at 17. It will be understood that the key may be provided with turning heads or handles of other specific formations, if so desired.
- the front end portion 8' of the key is slit longitudinally from its front end to form a longitudinally extending slit or slot 18 and as this slot is open at its front end the free end portion 19 of the sealing strip 1 may be fitted into this slot when the can opener is applied to the can.
- the key is grasped by its handle 14 and turned. Since the arms 7 of the cross head or yoke -6 bear against the can 2 and the cover 3 above and below the sealing strip, the sleeve will be prevented from turning with the key and as the key is turned the strip will be torn loose and wrapped about the forward portion of the key and thus form the strip into a coil 20. After the strip has been entirely torn loose from the can and coiled about the forward portion of the key, it is merely necessary to grasp the sleeve and exert rearward pull upon the key.
- the coiled strip does not remain upon the key and a person does not have to uncoil it from the key in order to remove it as is the case with can openers of this type wherein the free end of the sealing strip is passed through a slot or slit formedin the key and closed at both ends.
- Figs. 5, 6 and 7 there has been illustrated a modified construction.
- the key 21 passes through a block or cross head 22 from which extend arms 23. These arms are bent laterally as shown at 24 and then forwardly as shown at 25 to provide portions which correspond to the arms 7 of the cross head 6.
- Pins or equivalent members 26 and 27 are carried by the key and by engagement with the front and rear surfaces of the cross head 22 they prevent sliding movement of the key but at the same time allow the key to be freely turned in the bore of the cross head 22 through which it passes.
- the rear end of the key 21 is formed with a handle or turning head 28 corresponding to the handle 14 and the portion of the key in front of the cross head 22 is formed with a slot or slit 29 which leads from the front end of the key and is, therefore, open at its front end.
- This slot corresponds to the slot 18 and when this form of can opener is in use, the free end of the sealing strip is passed through the slot 29 and the key then turned so that the strip will be torn loose and wrapped about the key in a tight coil.
- a stem 30 which extends longitudinally of the key and is disposed within the slot 29.
- a button 31 is mounted through the stem 30 close to the rear end thereof and when the coiled strip is to be removed it is merely necessary to grasp the button between the thumb and finger and slide the stem 30 forward- 1y. As the stem is slid forwardly its front end engages the portion of the strip which passes through the slot and pressure'will be exerted to force the coiled strip forwardly and off of the front end of the key. Since the button is of such dimensions that it may move through spaces between sides of the key and the arms 23, it will not interfere with turning movement of the key.
- Abutment members 32 which are carried by the key 21 at opposite sides of the slot project from the key in position for engagement by the heads of the button 31 and serve to limit forward movement of the stem 30 beyond the position indicated by dotted lines in Fig. 6.

AT TORNE YS United States Patent CAN OPENER Pearl' C;Woolfolk, Camden, N. J. Application August 13, 1953, Serial No. 373,949 13" Claims. Ci. nit-'52 I This invention relates to can openers of the type used for removing a sealing strip extending about a can of the vacuum sealed type. v V
Openers which are usually employed for opening such cans consist of a key having a shank provided adjacent one end with a slot or eye in which a free end of a sealing strip is fitted, the other end of the shank carrying a cross head or the like by means of which the key is turned in order to wrap the strip about the shank and progressively tear the strip loose from the can and its cover until the strip is entirely removed and the cover released for removal from the can.
Such can openers are not entirely satisfactory as the strip has a tendency to wind unevenly about the shank of the key instead of forming an even compact coil and in addition it is di-fiicult to remove the coiled strip from the key after it has been entirely torn loose from the can and the cover. Therefore, the key is usually thrown away with the strip wrapped about it, thus avoiding the trouble of unwrapping the strip from the key and also eliminating likelihood of the strip cutting a persons fingers while unwrapping it from the key.
Therefore, one "object of the invention is to provide a can opener including a key adapted for detachable engagement with an end of a can-sealing strip and rotatably mounted through the shank of a yoke which guides wrapping movement of the strip about the key into a tight coil and prevents portions of the strip from slipping transversely off of the coil as it is torn loose from the can and wrapped about the key.
Another object of the invention is to provide a can opener of such construction that a sealing strip may be easily and accurately wrapped in a coil about a key but allow the strip to be readily removed from the key in its coiled condition and thus eliminate unwinding of the strip from the key in order to remove it.
Another object of the invention is to provide a can opener of this type wherein a portion of the key is slidable longitudinally as well as being rotatable relative to the yoke, the said key being formed with a strip securing slot which is open at its front end so that a coiled strip may be shifted along the key and otf at the front end thereof when removing the coiled strip from about the key.
Another object of the invention is to so mount the key that while its longitudinal movement will normally be limited it may be entirely removed when repairs or a thorough cleaning are necessary.
With these and other objects in view, the invention is illustrated in the accompanying drawings wherein:
Fig. l is a View in elevation showing the implement applied to a sealing strip of a can;
Fig. 2 is a view looking at "the front end of the implement;
Fig. 3 is a view showing the implement partially in Fig. 4 is a view similar to Fig. 3 showing the key in a retracted position;
"ice
Fig. 5 is a view in elevation of a modified form of implement;
Fig. 6' is a view showing the modified form of implement partially in elevation and partially in section;
Fig. 7 is a view looking at the front end of the implement shown in Fig. 5.
This improved can opener is used for removing the sealing strip 1 which extends circumferentially about a can 2 and holds the cover 3 in place. Such a can is of a conventional construction and is used for storing various materials in a vacuum sealed container.
The sleeve or shank 4 consists of a metal tube formed with a bore 5 which extends its full length and is open at both ends. A cross head 6 extends across the front end of the sleeve or tube 4 and at its ends this cross head carries arms 7 which are of such length that when the device is applied to a can the arms will extend across the sealing strip 1. A key 8 which is formed of stilt metal extends through the bore of the sleeve 4 and is of such length that it may protrude from front and rear ends of the bore. Within the sleeve a portion 9 of the key is of reduced thickness thus providing the key with circumferentially extending abutment shoulders 10 and 11, at front and rear ends of the reduced portion 9.
A set screw 12 is screwed into a threaded opening 13 formed through a side portion of the sleeve and is of such length that it may extend into the bore of the sleeve and constitute a stop for engaging the shoulders 19 and 11 and thus limiting sliding movement of the key when moved from the extended position for use shown in Fig. 3 t0 the retracted position shown in Fig. 4.
The fact that the reduced portion 9 of the key is circular in cross section allows the key to be turned in the sleeve as well as slid longitudinally through the sleeve when the sleeve is grasped by the head or handle 14 which has been shown substantially triangular and is formed by bending the metal rod from which the key is formed so that it extends diagonally from the key as shown at 15 and then transversely towards the other side of the key as shown at 16 and then forwardly at an inward incline toward the key as shown at 17. It will be understood that the key may be provided with turning heads or handles of other specific formations, if so desired.
The front end portion 8' of the key is slit longitudinally from its front end to form a longitudinally extending slit or slot 18 and as this slot is open at its front end the free end portion 19 of the sealing strip 1 may be fitted into this slot when the can opener is applied to the can.
After the free end of the sealing strip has been engaged in the slot the key is grasped by its handle 14 and turned. Since the arms 7 of the cross head or yoke -6 bear against the can 2 and the cover 3 above and below the sealing strip, the sleeve will be prevented from turning with the key and as the key is turned the strip will be torn loose and wrapped about the forward portion of the key and thus form the strip into a coil 20. After the strip has been entirely torn loose from the can and coiled about the forward portion of the key, it is merely necessary to grasp the sleeve and exert rearward pull upon the key. This will slide the 'key .rearwardly through the bore of the sleeve until the innerend of the screw 12 engages the abutment shoulder 10 and limits rearward movement of the key beyond the retracted position shown in Fig. 4. As the -key is drawn rear-wardly, the-coiled strip engages portions of the cross head about the rearwardly moving key 'and as rearward movement of the key towards the retracted position is-continued, the coiled strip will :move oifof the front end of the key and thus be entirelydetached from the key. The coiled strip may then be discarded and the-can opener .put away'unti it .is again needed.
It will thus be seen that the coiled strip does not remain upon the key and a person does not have to uncoil it from the key in order to remove it as is the case with can openers of this type wherein the free end of the sealing strip is passed through a slot or slit formedin the key and closed at both ends.
In Figs. 5, 6 and 7 there has been illustrated a modified construction. In this embodiment of the invention the key 21 passes through a block or cross head 22 from which extend arms 23. These arms are bent laterally as shown at 24 and then forwardly as shown at 25 to provide portions which correspond to the arms 7 of the cross head 6. Pins or equivalent members 26 and 27 are carried by the key and by engagement with the front and rear surfaces of the cross head 22 they prevent sliding movement of the key but at the same time allow the key to be freely turned in the bore of the cross head 22 through which it passes. The rear end of the key 21 is formed with a handle or turning head 28 corresponding to the handle 14 and the portion of the key in front of the cross head 22 is formed with a slot or slit 29 which leads from the front end of the key and is, therefore, open at its front end. This slot corresponds to the slot 18 and when this form of can opener is in use, the free end of the sealing strip is passed through the slot 29 and the key then turned so that the strip will be torn loose and wrapped about the key in a tight coil. In order to remove the coiled strip from the front end portion of the key 21 there has been provided a stem 30 which extends longitudinally of the key and is disposed within the slot 29. A button 31 is mounted through the stem 30 close to the rear end thereof and when the coiled strip is to be removed it is merely necessary to grasp the button between the thumb and finger and slide the stem 30 forward- 1y. As the stem is slid forwardly its front end engages the portion of the strip which passes through the slot and pressure'will be exerted to force the coiled strip forwardly and off of the front end of the key. Since the button is of such dimensions that it may move through spaces between sides of the key and the arms 23, it will not interfere with turning movement of the key.
Therefore, the stem cannot be moved forwardly out of engagement with the key and be lost.
