ROBERT L. WELLS, OF CHICAGO, ILLINOIS.
CAN OPENER.
7 Application filed June 16, 1921. Serial No. 477,947.
- .To all whomit may concern.
Be it known that I, ROBERT L. WELLS, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Can Openers,
ofwhich the following is a specification.
This invention relates to can opening machines, and has for its object the provision of a simple machine which will cut out I' the ends of cans of various sizes in an expeditious manner.
It has been common practice heretofore to use various means for opening cans. none of which has been entirely satisfactory, as the small can openers are awkward and uncertain in use, and in opening larger cans it is common practice to use a hatchet or like instrument. By using my machine I can cut out the tops of cans of various i: :sizes quickly and neatly.
;ing machine embodying my invention,
Fig. 2 is a front elevation partly in section of such machine.
Fig. 3 is a detail view on line 33 of F igkl,
Fig. 4: is a detail view on line 41-4l of I i Fig. 1.
In the drawings, 1 represents a standard of any desired constructlon, havlng a suitable base 2 which may be secured in ".liany desirable location, preferably conveniently near a power plant. A shaft 3 may have one end journalled in said standard 1. and its other end journalled in a bearing 4.- atthe end of arm 5 on said standard.
At the end of the shaft 3 is keyed a pulley 6 which may be driven by a belt 7 connected to any suitable source of power. A pulley 8 is also keyed on said shaft 3, and transmits power to two smaller pulleys 9 and 10 mounted on said standard 1 above said pulley 8, and preferably disposed at right angles thereto.
The standard 1 is also preferably provided with arms 17 and 18 in the bear- .; ings 15 and 16 of which is journalled a shaft 11. The pulley 12 is preferably mounted on the shaft 11 as shown. The belt 13 engages the pulleys 8, 9, 10 and 12 to drive the shaft 11. The outer endof the shaft 11 may be provided with a suitable collar 14: to support same in position. If desired, the collar 14. may be provided with ball bearings; and any of the other bearings in the machine may be of this type if deemed desirable. As illustrated, the machine comprises as few parts as are consistent with smooth and positive operation, but I consider refinements of parts of my machine as within the scope of my invention.
I preferably provide a can centering detachable chuck 19 of any desirable size which is preferably provided with a sleeve 20 which engages a suitable bore in the hearing 16, and a set screw 21 may be tapped through said bearing to hold the chuck securely in position. Chuck 19 preferably has its lower inner edges outwardly bevelled as shown at 19 for a purpose hereinafter described. Chucks similar to 19, but of different sizes, may be substituted one for the other when'operating on cans of different sizes.
The lower end of shaft 11 is preferably journalled in a collar 21 secured in bearing 16 as shown, and to the end of said shaft is detachably connected a disk 22 which is adapted to rotate with said shaft. The disk 22 may be connected to said shaftin any suitable manner, but is shown as having a threaded socket engaging the threaded end of said shaft, the direction of rotation of the disk of course being such as to engage the disk tightly on shaft 11.
I preferably mount a tapered knife blade 23 on periphery of disk 22 which blade rotates with said disk. The disk 22 is detachable, and a similar disk, having a knife 28, may be substituted therefor when operating on cans of different sizes.
In order to bring a can into engagement with the cutting knife 23, I preferably provide a circular detachable interchangeable platform 24, which may be provided with an annular flange 25 extending therearound to retain a rubber pad or the like in position. The platform 24. is preferably provided with a boss 25 on its undersidie, which has a socket into which is inserted the end of a rod 27. A set screw 28 may be tapped through said boss 25 to engage said rod 27;. and secure same to the platform. The platform 24 also is' preferably provided with a bracket 29 on its underside into which is inserted a rod 30 carrying an angular bar 31, having forked fingers 32, the inner sides of said fingers being adjustable to engage a can to position same on the platform 24.
I also preferably provide suitable means forfraising-and lowering said can and platform intoengagement with the knife 23,
and out of engagement therewith after the top of the'can has been cut. As shown, an
arm'32 carrying a guide 33 having retainlng'flanges 341s provided. A slide 35 1s atl'apted'to moveup and down in the guide The'o'uter face of slide 35 has provided 'at'one endupst'anding ears 36 which engage theend of rod 27 as shown, and are clamped thereon by aset screw, the other end of said slide also having ears 38 which engage a li'nk '40"whi'ch link is pivotally secured "theretoby a pin 39 t'ransfixing said ears.
The lower end of link 40 is bifurcated and pivotally secu'red'to a lever 41, which is pivoted to the standard 1 at 42, as shown, the
ot'her'end of said lever 41 being connected by link' 45to a lever 43, and pivoted to the j standard'l at 44. The lever 43 carries at its'o'uter-enda foot-piece 46. A spring 47 ispijovided for normally retaining the lever 43inraised position.
P'A'sabove stated the machine is capable of' operating on cans of different diameters. This is accomplished by providing a numberof' chucks 19-and disks 22 of various o'f'a larger size than shown, for instance, the
chine in a similar manner so that the mach ineis capable of operating on cans varyln'g fgreatly 111S1Ze. The platform 24 is also iInoperation a chuck 19, disk 22, and platform '24 of the desiredsize 'areplac ed' in position, andth'e power turned on. The fingers '32- are adjusted to position the cans on the platform 24. The lever 43 is then p'ressed-(asshown in Fig. 1) thereby raising' th'e" can into engagement with the bev- VVhen it is desired to operate on cans platform elled edges 19" of the chuck-19 to center the can and 'hold'same in position, the rotating knife at the same time piercing the can top While I have illustrated and described" the preferred form of construction for carryin my invention into effect, this is capable of variation and modification without departing from the spirit of'the invention.
