Improvements in Securing Tools and the like to their Handles.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan and Co., of
18 Buckingham Street, Strand, W.C., London, Civil Engineer, do hereby
declare the nature of this invention a communication to me from abroad by
Horace Stephen Buckland, of Fremont, in the County of Sandusky, and State of
Ohio, United States of America, Attorney-at-Law and Manufacturer, and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
This invention relates to improvements in securing-devices for fastening the
working-member of a tool, such, for instance, as an awl or screw-driver or knife-
blade within a chambered handle, ferrule, shell or holder, the object being to
provide a securing-device for the purpose indicated that is exceedingly simple in
construction and inexpensive; that possesses great durability and can be easily
applied, and whereby the member of the tool, to be secured within the handle,
ferrule or holder, is so firmly held in place that it is not liable to work loose in the
use of the tool.
With this object in view, my invention consists in certain features of construction,
and in combinations of parts hereinafter described and pointed out in the claims.
In the accompanying drawings,

page_text: Referring to the drawings, A designates a chambered handle, ferrule or holder
into which is introduced and suitably secured the shank b of the working member B
of the tool, such for instance, as an awl, illustrated in Figs. 1, 2, 4 and 5, or a knife
blade, as shown in Figs. 7, 8, 11, 12 and 13.
The means for securing the working member B of the tool within the handle,
ferrule or holder is formed preferably of a single piece of metal, said piece being
preferably shaped as shown in Figs. 3 and 9 and comprising three members C¹, C¹,
and C arranged in line, as shown, with the two end members C' C substantially
the same in construction and adapted when bent laterally as will hereinafter appear,
to fit the handle, ferrule or holder internally. The blank is bent into the shape
shown in Figs. 6. and 10, that is, the central member C2 of the blank, at two points
located a suitable distance apart, is bent laterally as at C³, in the same direction
and on lines extending longitudinally of the blank and the end members C', C¹, at
the junction of said members with the central member C2, are bent laterally in the
same direction so as to be capable of being subsequently folded or pressed against
the adjacent end of the laterally bent portions or wings C³ of member C³, wings or
members C³ forming stops to prevent members C¹ C¹ being pressed toward each
other too far. The end members C¹ C³ of the blank, at or near the central
portion, are perforated laterally, as at C, to accommodate the reception of the
knife blade or working member B of the tool.
Each member C₁ of the blank is provided with two slots or slits C³ in open
relation with perforation C in order to form a lip or tooth C. The central
perforations or holes Care of such size and shape as to nicely receive the shank b
of the working member B of the tool, and lips or teeth C are bent or project
somewhat outwardly, as shown in Figs. 4, 6, 10 and 11, so that when the parts are
assembled and secured in place, as shown in Figs. 1 and 7 with members C¹, C³,
tightly engaging the handle or ferrule internally, lips or teeth Co formed upon
members CC are straightened into line with the body portion of the respective
member C¹ and thereby caused to bite or tightly engage the adjacent portion of
shank of the working member B of the tool, resulting in firmly securing the
working member of the tool within the handle, ferrule or holder.
In Figs. 1 and 2, the working member of an awl is shown secured within the
handle of the tool by a securing device embodying this invention. In Figs. 7 and 8
a knife blade is shown secured within the handle or holder by this improved
securing device.
In Figs. 8, 9 and 10 lips or teeth C6 of the securing device are of such size that
when they engage the working member B of the tool they will also engage the
laterally bent members or wings C³ of the central member C of the blank as
shown in Fig. 8.
End members C¹, C¹, and their lips or teeth C, are preferably bent or straightened
against the adjacent ends of wings or stops C³ of the central portion of the securing
device by pressure afforded by any suitable tool introduced into one end of the
handle, ferrule or holder at one end of the securing device, and an abutment, such,
for instance, as the inner end wall a of the socket in the handle, if the latter be
of the construction shown in Figs. 3 and 4 or the abutment formed by the disc or
plate D shown in Figs. 7 and 11 at the opposite end of the securing device,
prevents the securing device and working member B of the tool from being
displaced within the handle, ferrule or holder by the pressure employed in fastening
the parts together, as herein before described.
The abutment referred to, may, however, be dispensed with if the handle or
holder is tubular so that pressure may simultaneously be brought upon each end of
the securing device.
In case an abutment plate or disc D, as shown in Figs. 7 and 11 is employed in
the holder or handle illustrated in said figures, the working member B of the tool
is provided with a shoulder B₁ formed upon member B and engaged by the
abutment plate or disc.
The shank of blade or member B, where the latter is embraced by disc or

page_text: plate D, when the latter is in position abutting shoulder B', is preferably reduced
in size, as at 6' thereby forming a recess 6. Disc or plate D is slotted or perforated
laterally as at D¹ to enable it to be slipped (see Fig. 13) over one end, preferably
the shank end, of blade or member B into the position embracing the reduced
portion 6 of the knife blade, and said perforation D' is enlarged centrally as at D'
(see Figs. 12 and 13) to enable the disc or plate and knife-blade to be turned
relative to each other when the disc or plate is in position abutting shoulder B'.
The enlarged portion D2 of the slot or perforation D¹ in disc or plate D is just
large enough to receive the reduced portion of the knife blade and to permit or
accommodate the turning of the knife blade within the plate or disc when the
latter is in position abutting shoulder B. Hence it will be observed that when
said disc or plate is in position, with the enlargement D² of slot D¹ engaged by
reduced portion of the knife blade, as shown in Figs. 7 and 12, shoulder 6³ that
constitutes an end wall or recess 62 forms a stop to prevent the displacement of said
disc or plate from the knife blade.
It will be observed by this improved construction the knife blade or working
member of the tool is arranged centrally relative to the receiving handle, ferrule or
holder, and I would also remark that recess 62 in the knife blade or working
member of the tool is enlarged as at (see Figs. 7 and 11) to receive the adjacent
lip or tooth C of the securing device, said lip or projection being large enough to
enter the recess when the parts are secured in place as hereinbefore described, and
as shown in Fig. 7. By the construction hereinbefore described, it is obvious that
the knife blade or working member of the tool cannot possibly become displaced
endwise, or work itself loose, in the operation of the tool.
I would also remark that the two slits C³ made in the blank in the formation of
lips or teeth Co, diverge from the connecting perforation C, as shown very clearly
in Figs. 8 and 10, the object being to make the lips or teeth of such size that they
shall engage with wings or stops C³ of the central member of the blank in the final
operation of securing the parts together and be thereby positively bent into the
position required to properly engage the shank of the knife blade or working
member of the tool.
I would remark that shoulder B' on knife blade or member B might be employed
alone as an abutment for the securing device, but I prefer the use of the abutment
disc or plate herein before described.
In Fig. 14 is illustrated a securing device made in halves or two pieces.
I would also have it understood that this invention is not confined to the
employment of stops C³ between the two securing members C', C' of the securing
device, for it is obvious that any two members C', C', located a suitable distance
apart embracing the working member of the tool and fitting the handle, ferrule,
steel or holder internally and provided with lips or teeth C adapted to frictionally
engage the working member of the tool, would constitute a good securing-device
for the purpose indicated.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is :-
1. A device for securing the working member of a tool within a ferrule, handle
or holder, consisting of two securing members located a suitable distance apart and
