WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO FASTENINGS
FOR UNITING AND SECURING THE ENDS OF BALE TIES OR BANDS." [A communi-
cation from abroad by Samuel Hidden Gilman, of New Orleans, Louisiana, United
States of America, Civil Engineer.]
The object of this Invention is to furnish a self-fastening bale tie that will unite
the two ends of a metal band which has had no previous preparation whatever, such
as doubling, bending, slotting, punching, serating, cramping, or the like.
The said Invention consists chiefly in the peculiar form of the part of the
fastening in which the ends of the band are secured, and in the combination there-
with of globes or balls, as herein-after specified.
The exterior form of this improved bale tie is parallelogrammic in horizontal
section, and pyramidic in vertical section. Its interior is in its general form
parallelograminic in horizontal section, and pyramidic in vertical section, Both
sides of the interior parallelogram are corrugated vertically, that is to say, they
have three corrugations, or more or less, as may be found most efficient. These
corrugations on the front side are for the purpose of keeping the globes or balls
separated, and thus securing an equal distribution of their pressure on the width of

page_text: the band. The corrugations on the back are for the purpose of increasing the
friction of the end of the band against the tie, and against the other end of the
band, the two being pressed together. The front lines of the divisions between
the corrugations are all parallel to each other, and of such a distance apart that
after the globes are all put in, and one end of the band is passed through, none of
the globes can change place or escape from the tie. A lip at the top closes the
apertures, so that the globes cannot escape while the end of the band is in its
place.
For the convenience of handling one end of the band is bent over sufficiently to
prevent the slipping of the tie.
When thus ready for use the opposite end of the band is pushed into and
upwards from the bottom of the interior, rolling the globes up into the wider end
of the pyramidic interior until the band finds space to pass the globes, and is drawn
up to the desired strain, when the slightest reverse movement of the end of the
band rolls the globes downward in direction of the apex of the pyramidic interior,
and pinches the two ends of the band into the corrugations until both are fastened
by the friction, which becomes greater than the full strength of the bands.
.
In order to obtain this result, and leave the tie and band in a condition to be
separated again for repeated use, the two sides of the interior must be in vertical
section at an angle to each other of 75 degrees, as I have found that at that angle
a wedge will neither slip nor become fast when under pressure.
The stationary end of the band having both of its flat sides exposed to friction
is held to the tie by double the force of the opposite end, one side only of which is
exposed to friction.

according to this Invention.
Figure 2 is a horizontal section on the line G, H.
Figure 3 is a horizontal section on the line L, M, with the globes shown in plan
and the bands in section, as when fully fastened.
Figuro 4 is a vertical section on the line A, B, with the said globes shown in
clevation.
Figure 5 is a vertical section on the line C, D, with the said globes in elevation,
and the entire band in section, as when fastened.
The exterior form of this improved bale tie is parallelogrammic in horizontal
section, and pyramidic in vertical section; its interior is in its general form parallel-
ogrammic in horizontal section, and pyramidic in vertical section. Both sides of
the interior parallelogram are corrugated vertically, that is to say, they have three
corrugations, or more or less, as may be found the most efficient. These corru-
gations on the front side are for the purpose of keeping the globes or balls separated,
so that there is an equal distribution of their pressure throughout the width of the
band. The corrugations on the back are for the purpose of increasing the friction
of the end N of the band against the tie, and against the other end 0 of the band,
the same being pressed together, as shewn in Figure 5, inasmuch as this friction
constitutes the holding power of the tie. The front lines of the divisions between
the corrugations are all parallel to each other, and such a distance apart that after
the globes are all put in, and one end of the band N is passed through the tie, none
of the globes can change places or escape from the tie. The lip P at the top closes
the aperture, so that the globes cannot escape while the end Ñ of the band is in
its place.
For the purpose of bandling incidental to transportation and application the
end N of the band is bent over sufficiently to keep the tie from slipping off.
When thus ready for use the opposite end O of the band is pushed into and
upwards from the bottom of the interior of the tie, thereby rolling the said globes
up into the wider end of its pyramidic interior until the band finds space to pass
the globes, and is drawn up to the desired tension or strain, when the slightest
reverse movement of the end of the band rolls the globes downward in the
direction of the apex of the pyramidic interior, and pinches the two ends of the
band in the corrugations until both ends are fastened by the friction, which exceeds
the full strain on the bands.
To obtain this result, and leave the tie and band in a condition to be separated
again for repeated use, the two sides of the interior must be in vertical section at

page_text: an angle to each other of about 75 degrees, as at that angle a wedge will neither
slip nor become fast under pressure.
The stationary end N of the said band having both of its flat sides exposed to
friction is held to the tie by double the force of the opposite end O, one side only
of which is exposed to friction; and in the testing machine it is found that the
end N never moves in the tie when under a strain, and it is shown doubled down
solely for the purpose above specified.
Having thus fully described the said Invention, as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim, a bale tie with a pyramidic or semi-pyramidic aperture, either plain
or corrugated, and provided with a metal globe or ball, or two or more of the same,
placed within the said aperture, and in contact with the moveable end of the band
in such a manner that the said ball or balls will roll from the base toward the apex
of the tie in the act of fastening the two ends of the band which have been
inserted from opposite sides of the aperture, and thereby press both ends of the
band against the plain or corrugated surface of the said aperture until the friction
thus produced exceeds the strain on the band, as above set forth.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty-sixth day of December, in the year of our Lord
One thousand eight hundred and seventy-eight.
