NVENTOR Bg/ VM ATTORNEY Patented Nov. 10, 1936 UNITED STATES PATENT OFFICE METAL FERRULE Application April 27, 1933, Serial No. 668,166
8 Claims.
This invention relates to metal ferrules for joining one fibre member to another. More specifically, the invention is directed to a metal ferrule adapted for securing a bre disk to a fibre walled container.
The present invention is a specic improvement in the metal ferrule disclosed in my copending application entitled Improvements in container and method of making same, Serial l0 No. 605,571, filed April 16, 1932, which became Patent No. 1,959,971 on May 22, 1934.
Some of the objects of the present invention are to provide a toothed ferrule having maximum strength of teeth combined with minimum cutting of the bre disk, to provide a tooth having a strong base integral with the ferrule, a narrow shaft and a strong point and to provide a ferrule of the desired strength and durability without waste of metal.
In the accompanying drawing, similar characters of reference in the several gures indicate similar parts.
Figure 1 is a sectional view of one end of a container employing the ferrule of the present invention, the teeth being unclinched and the outer edge of the ferrule being unswedged to more clearly bring out the construction.
Figure 2 is a plan View of a portion of a metal blank showing the manner in which two complementary ferrules are prepared from a single strip of metal without waste.
Figure 3 is a plan view of a single tooth.
Figure 4 is a perspective View of the top of a container employing the ferrule of the present invention.
For convenience, measurements are indicated on the several figures of the drawing to illustrate an embodiment of the present invention suitable for a standard fourteen ounce cleanser container employing a bre disk 2.953 inches in diameter and .060 inch in thickness and a bre cylinder having an outside diameter of three and oneeighth inches and a wall thickness of one-sixteenth of an inch.
Two ferrules I may be formed from a single metal blank 2. It will be noted that the two ferrules, so formed are identical in size and shape. Each ferrule may be considered as comprising an unbroken strip 3 and a plurality of teeth 4. The strip 3 may be considered as being made up of two areas, base area 5 and area 6. Area 6 is rectangular and separates the teeth 4 from the base area 5 merging with and integral with each. Base area 5 is that portion of strip 3 dened by edge 'I, flaring ends 8 and an imagi- (Cl. 22B-5.7)
nary line parallel with edge 1 terminating at points 9 at which points 9 flaring ends 8 merge with straight ends I0 of area 6. The ends I0 extended form an angle of 8 with flaring ends 8 and thus it will be seen that base area 5 has 5 its greatest length along edge 1. 'I'his feature prevents a gap occurring at the point of juncture when the ferrule is in position upon the finished container with the edge 'I swedged on the wall 2| as shown in Figure 4, and permits of a small l0 overlap. A shoulder I I is preferably provided at one end of each ferrule to provide an overlap of the area 6 when the ferruleV is in position on the nished container.
Each tooth 4 may be considered as comprising 15 a base I2, a shaft or median portion I3 and a point I4, terminating in a tip I5. Base I2,.shaft I3 and point I4 are equal in length. The longest dimension of base I2 is twice as great as the width of shaft I3 and the sloping sides I6 and 20 II of base I2 are parallel respectively with sides I8 and I9, extended, of point I4. An imaginary line drawn through tip I5, parallel alike with the longest dimension of base I2 and edge 'I forms with each of the sides I8 and I9 of point I4, an 25 angle of 52 20. Consequently, sides I 8 and I9 of point I4 form at tip I5 an angle of 75 20'.
This angle forms a tip I5 which is sharp enough to readily pierce the bre disk 20 and yet which is blunt enough to resist distortion 30 when forced into disk 20.
When the ferrule is in position on the inished container only the teeth 4 are in contact with the disk 20. The base I2 lies flat upon the outside surface of the disk, the shaft I3 passes 35 through the fibre and the points I4 are clinched back flat against the inside surface of disk 20 such that each point is positioned directly opposite its base.
As win be noted in Figure 1, nbre disk 2o is 40 slightly less in diameter than the inside diameter of container 2I. This permits the disk with ferrule I attached thereto to slip easily into position. During the swedging operation the edges of the can body are forced into contact with the edge of the disk, thereby forming a substantial seal.
I claim:
1. A ierrule blank comprising a relatively long 50 strip having flaring ends and provided along one edge thereof with a plurality of blunt pointed teeth.
2. A ferrule blank comprising a relatively long strip having flaring ends, provided along one edge 55 thereof with a plurality of blunt teeth and having a straight edged shoulder at one end of said strip.
3. A ferrule blank comprising a relatively long strip having aring ends, a shoulder at one end of said strip and a plurality of blunt teeth along one edge of said strip each of said teeth having a broad base portion tapering to a narrow median portion, said median portion merging With a point portion.
4. A ferrule blank comprising a relatively long strip having ilaring ends, a shoulder at one end of said strip and a plurality of blunt teeth along one edge of said strip each of said teeth having a broad base portion tapering to a narrow median portion, said median portion merging with a point portion, said base portion, median portion and point portion being substantially equal in length.
5. A ferrule blank comprising a relatively long strip provided along one edge thereof with a plurality of blunt teeth, each of said teeth having a broad base portion tapering to a narrow median portion, said median portion merging with a point portion.
6. A ferrule blank comprising a relatively long strip provided along one edge thereof with a plurality of blunt teeth each of said teeth having a broad base portion tapering to a narrow median portion, said median portion merging with a point portion, the sides of said point portion forming an angle of substantially 75.
7. A ferrule blank comprising a relatively long strip provided along one edge thereof with a plurality of blunt teeth, each of said teeth having a broad base portion tapering to a narrow median portion, said median portion merging with a point portion, said base portion, median portion and point portion being substantially equal in length.
8. A ferrule blank comprising a relatively long strip provided along one edge thereof with a plurality of Ablunt teeth, each of said teeth having a broad base portion tapering to a narrow median portion, said median portion merging with a point portion, said base portion, median portion and point portion being substantially equal in length, and the sides of said point portion forming an angle of substantially 75.
