WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. AN IMPROVED DEVICE FOR SECURING IN ITS
PLACE A BOLT OR SIMILAR ARTICLE" [A communication from abroad by George
B. Taylor, Joseph Wood, and Benjamin Stephen Clark, all of the United States of
America.]
This Invention relates to a device comprising a key or gib for locking or holding
a bolt in its position, so that no jar or shake will cause the same to fall out, and
consists in the peculiar construction of the gib in combination with a spring, as
hereinafter described.
In carrying the said Invention into practice I employ a bolt having a head at
one end and provided in its other end with a key-hole. Upon this bolt I arrange
a spiral spring, which tends to force the said bolt outward; or any other spring or
equivalent device that will serve this purpose may be employed. My improved
gib or key is so constructed that it has at one side a recess, and at the other side a
projection. When my improved gib or key is to be inserted the bolt is pressed
inward against the force of the aforesaid spring until the said bolt passes far
enough through its hole to allow the keyhole to appear. The said keyhole is
larger than the key. When the bolt is thus pressed inward the key is slipped
into the said keyhole, and the pressure upon the said bolt is removed, so that the
spring presses against the head of the same and pulls the said bolt tight against
the key, so that its end rests in the recess in the gib or key projections at the enda
of the said recess, serving to prevent the said key from slipping. At the same
time the projection on the said gib or key has been forced into the hole or opening
in the part through which the bolt passes, and thus the key is prevented from
slipping both at its front and back. The aforesaid key may be made of any metal
suitable for the purpose.

WILLIAM ROBERT Lake, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED DEVICE FOR SECURING IN ITS
PLACE A BOLT OR SIMILAR ARTICLE." A communication from abroad by George
B. Taylor, Joseph Wood, and Benjamin Steven Clark, all of the United States of
America.
This Invention relates to a device comprising a key or gib for locking or holding
a bolt in its position, so that no jar or shake will cause the same to fall out, and the
said Invention consists essentially in the peculiar construction of the key or gib,
and its use in combination with a spring, as hereinafter described. In the
accompanying Drawing,―
Figure 1 represents a plan or top view, showing the said Invention as applied to
a bolt, serving as a pivot for a lever, but it may be applied in a similar manner to
a ratchet, or to many other devices in which bolts are employed.
Figure 2 is a sectional view on the line x, x, Figure 1; and
Figure 3 is a side view of my improved gib or key.
A is a bolt having a head a at one end, and provided at its other end with a
key-bole; B is a spring, which, as shown in the Drawing, is spiral, and surrounding
the said bolt A, but any equivalent device, such as an india-rubber ring, that will
serve the purpose of this spring-may-be-employed.;-D.is.my-improved.gib.or_key,
which is provided with the recess & and the projection e. It will be evident that
when the spring is placed upon the bolt, as shewn, the pressure of the said spring
will tend to force the said bolt out, but by pressing the latter inward against the
force of the aforesaid spring the said bolt is caused to pass far enough through its
hole to allow the gib or key to be inserted in the keyhole b. The said keyhole is
larger than the key, and when the bolt is thus pressed inward and the spring B
compressed, the key D is slipped into the keyhole till the nib or projection / has
passed the side of the bolt, and the pressure upon the said bolt is then removed, so
that the spring presses against the head of the same, and pulls the said bolt tight
against the key. As the bolt now rests in the recess d, the projections h, h', in the
gib or key prevent the said key from slipping. At the same time the projection e
has been forced into the bolt hole, as shown in Figure 2, and thus the key is held
both at its front and back, and prevented from slipping out. The aforesaid key
may be made of any metal suitable for the purpose.
Having thus fully described the said Invention as communicated to me by my
foreign correspondents, and the manner of performing the same, I wish it understood
that I claim,
First. A bolt gib or key D constructed with a recess d, and projections h, h', in
combination with a bolt and spring, substantially as shown and described and for
the purpose specified.
Second. A bolt gib or key constructed as set forth, in combination with a bolt
and spring, substantially as shown and described and for the purpose specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Third day of April, in the year of our Lord One
thousand eight hundred and eighty two.
