Improvements in Rivet Holders.
I, HENRY HARRIS LAKE of the firm of Haseltine Lake & Co., Patent Agents
45 Southampton Buildings in the County of Middlesex, do hereby declare the
nature.of this invention to be as follows:-
:
This invention relates to an improved hand rivet holder for holding rivets when
securing the same to any desired article to this end it consists, essentially, in a
plate formed with arms for engaging the rivet head, a spring plate for holding
the rivet head in engagement with said arms, and a clamp for securing said plates
together.
Rivets, and particularly that class termed bifurcated rivets, are now generally
used for many and various purposes, and have heretofore been generally attached
by automatic machines operated either by foot or steam power; but these rivets
are particularly applicable for attachment by hand, providing they are firmly held
when being attached:
The object of this invention is the production of a suitable tool for firmly grasping
and holding the rivet when being inserted into and clinched upon the article to
which it is to be secured.
This rivet holder is composed of two plates formed of spring metal, one being
formed with a slot for receiving the shank of the rivet, and with arms on opposite
sides of the slot for engaging the head of the rivet, and the other having its
extremity disposed above a portion of the slot in the former plate for engaging the
top face of the rivet head and constantly forcing the same into engagement with
the arms of the former plate, thus firmly securing the rivet to the holder.
After being engaged by the rivet holder, as just described, the rivet may then be
passed through the article to which it is to be secured, and upon clinching its
prongs by a suitable clinching tool it is then firmly secured in position, whereupon
the holder may be withdrawn.
To facilitate entrance of the rivet head between the respective plates forming the
rivet holder the under face of the top plate is inclined.
pass
The plates composing the rivet holder are usually rectangular in form, and are
provided at their central portion with apertures through which suitable clamps
as bifurcated rivets, thus enabling both extremities of the holder to be utilized for
engaging the rivets. The holder may also be composed with one extremity of
greater area than the other and provided with a series of slots of different widths
for engaging rivets of different sizes.
Dated this 23rd day of October 1891.

declare the nature of this invention and in what manner the same is to be
[Price 8d1

page_text: performed, to be particularly described and ascertained in and by the following
statement :-
:
This invention relates to an improved hand rivet holder for holding rivets when
securing the same to any desired article to this end it consists, essentially, in a
plate formed with arms for engaging the rivet head, a spring plate for holding the
rivet head in engagement with said arms, a clamp for securing said plates together,
and in the detail construction and arrangement of the parts, all as hereinafter more
particularly described and pointed out in the claims.
In describing this invention, reference is had to the accompanying drawing,
forming a part of this Specification, in which, like letters indicate corresponding
parts in all the views.
Figures 1, 2 and 3 are, respectively, top plan, inverted plan and side elevation
of this improved holder, a pair of rivets being shown as operatively engaged thereby
at Figure 3.
Figure 4 is a longitudinal vertical sectional view, taken on line 3--3, Figure 1.
Figure 5 is a transverse vertical sectional view, taken on line 5-5, Figure 1.
Figures 6 and 7 are isometric perspectives of the detached plates of the rivet
holder; and
Figure 8 is an isometric perspective of a modified form of this invention.
Rivets, and particularly that class termed bifurcated rivets, are now generally
used for many and various purposes, and have heretofore been generally attached
by automatic machines operated either by foot or steam power; but these rivets
are particularly applicable for attachment by hand, providing they are firmly held
when being attached.
The object of this invention is the production of a suitable hand tool for firmly
grasping and holding the rivet, when being inserted into and clinched upon the
article to which it is to be secured.
A represents a plate which is composed preferably of spring metal, is formed
with a slot a for receiving the shank of the rivet C, and with arms 6 on opposite
sides of the slot for engaging the head c of the rivet and thereby supporting the
same.
D is a spring plate having its extremity d disposed above a portion of the slot a
for engaging the top face of the rivet head c and constantly forcing the same into
engagement with the arms bb, thus firmly securing the rivet to the holder H.
After being engaged by the rivet holder, as just described, the rivet may then
be passed through the article to which it is to be secured, and upon clinching its
prongs by a suitable clinching tool it is then firmly secured in position, whereupon
the holder may be withdrawn.
To facilitate entrance of the rivet head between the plates A and D, under face
of the extremity of the plate D is inclined at d'.
At Figures 1 to 7 inclusive the plates A and B are shown as rectangular in form
and provided at their central portion with apertures E through which pass suitable
clamps F, here shown as bifurcated rivets having their heads f bearing against the
upper face of one plate and their prongs f¹ turned backwardly upon the underside
of the opposite plate.
By this construction, both extremities of the holder can be utilized to engage
rivets, and, as seen in the drawings, both extremities of the plates A are formed
with slots a; a portion of which is overlapped by the end of the plate D, and the
plate D is somewhat shorter than the plate A for facilitating the ready engagement
of the rivets by the holder.
At Figure 8 is shown the plates A and D as formed with one extremity of
greater area than the other and provided at said extremity with a series of slots a
of different widths for permitting the entrance of different sized rivets, which are
held in position by the overlapping edge of the plate D.
The operation of this invention will be readily perceived from the foregoing
description and upon reference to the drawing, and it is evident that its precise

page_text: detail construction and arrangement may be somewhat varied from that shown and
described.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to me
by my foreign correspondents I declare that what I claim, is:
1-In a rivet holder, the combination with a plate having arms for engaging the
rivet; of a spring plate for holding the rivet in position, substantially as set forth.
2-In a rivet holder, the combination with a plate having arms for engaging the
rivet; of a spring plate for holding the rivet in position, and a clamp for securing
said plates together, substantially as specified.
3-In a rivet holder, the combination with a plate having arms for engaging the
rivet, a spring plate for holding said rivet in position, apertures through said plates,
and a rivet passed through said apertures and formed with a bifurcated shank
adapted to be turned upon one of the plates, substantially as set forth.
4 In a rivet holder, the combination with a spring plate A formed with a slot a,
a second plate D secured to the former plate with a portion thereof imposed above
said slot a, substantially as described.
5-In a rivet holder, the combination with a plate D formed with inclined
edges dd, a plate A having slots a a at its opposite extremities beneath the
inclined edges d¹ d² and a clamp for securing said plates together, substantially as
specified.
