page_text: I, WILSON ANDREW KINDT, of 211, West Hanover Street, Trenton, New York,
United States of America, School Church Furniture Worker, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improvement in hand saws, and the object thereof is
to provide a simple and inexpensive handle for saws of this character which may
be readily detached from the saw blade and attached to another saw blade of
similar construction. Heretofore, tools of this character have been each supplied
with its own handle permanently fixed thereto. In transportation, the handles
take up a great deal of unnecessary room; furthermore, they are more expensive
than the applicant's device which requires but one handle to an unlimited
number of blades, an important item with carpenters who are obliged to carry
their tools from place to place in chests built for that purpose.
In applying my invention, I employ a saw blade having two wings, fixed
upon one end thereof by means of rivets, or they may be formed integrally with
the said blade.
A handle having the usual grip is provided upon its forward edge with a
metallic plate. One end of said plate is bent over the top of said handle and
is preferably countersunk into the wood of which the handle is composed. The
lower portion of said plate is bifurcated, forming two extensions thereon which
are secured to the handle, preferably by means of screws.
suitable slot in the wood of the handle registers with the bifurcation of the
metallic plate.
A bifurcated plate is pivoted to the upper portion of the metallic plate upon
the forward edge of the handle.
The slot in the bifurcated plate is narrower than the slot in the handle proper
and of sufficient width only, to receive the saw blade proper. The lower ends
of this said plate are curved rearwardly and upwardly to form a catch for lock-
ing the blade in position.
A locking device embodies the metallic plate having a slot therein, said slot
being cut in said plate transversely with relation to the handle. A downwardly
projecting lip forms a convenient finger grip for the manipulation of the locking
plate.
A longitudinal projection from the sliding plate is provided with a downwardly
extending lip, said lip being adapted to engage the upturned lower ends of the
bifurcated plate.
A screw is threaded into the lower portion of the handle, and upon the neck
of said screw the locking plate is adapted to slide.

page_text: In the operation of the device, the saw blade is entered in the slot of the
bifurcated plate, the wings being below said plate and the whole brought in
line with the slot. It is then pushed upward in said slot until it reaches the upper
end thereof. The locking catch is then slipped into position, effectually locking
the blade in position and preventing accidental displacement thereof.
To remove the blade, the catch is slipped out from engagement with the curved
ends of the bifurcated plate, and said curved ends similarly raised to clear the
wings of the blade. The blade may then be easily slipped out from the slot.
It is obvious that the bifurcated plate may be made of spring steel of suffi-
cient strength to act as its own catch; obvious too that a spring catch may be
employed to lock the said plate in position in place of the sliding catch described
and preferred. The upper end of this said plate instead of being pivoted on a
screw, may be hinged to the metallic plate.

I, WILSON ANDREW KINDT, 211, West Hanover Street, Trenton, in the State
of New York, United States of America, School Church Furniture Worker, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the follow-
ing statement :-
This invention relates to an improvement in handsaws; and the object thereof
is to provide a simple and inexpensive handle for saws of this character which
may be readily detached from the saw-blade and attached to another saw-blade
of similar construction.
The invention will be hereinafter fully described and specifically set forth in
the annexed claims.
In the accompanying drawings, Figure 1 is a side elevation of the device, the
blade being partly broken away. Figure 2 is an inverted plan view of the
same; Figure 3 is an end view of the blade detached from the handle. Figure 4
is an end view of the handle detached from the blade and shown in open posi-
tion.
In applying my invention I employ a saw-blade A, having two wings a fixed
near one end thereof by means of rivets, or it may be formed integrally with
said blade.
A handle B, having the usual grip, is provided upon its forward edge with a
metallic plate b. One end of said plate is bent over the top of said handle and
is preferably countersunk into the wood of which the handle is composed, as at b¹.
The lower portion of said plate is bifurcated, forming two extensions 62, 62
thereof, which are secured to the handle, preferably by means of screws b³, b³.
A suitable slot C in the wood of the handle registers with the bifurcation of
the metallic plate 6, and receives the rearward extension of the blade. Attached
to an integrally formed projection of the plate b, at its upper end, is a bifur-
cated plate D of resilient metal, which is movable and is preferably pivoted to
the said plate 6 by means of a screw d, which passes through the plate D and
threads into the plate 6, whereby the plate D is normally maintained in align-

page_text: ment with the plate b, as shown in Figure 1 of the drawings, when. the parts
are assembled. But the face of the plate 6 can be uncovered by swinging the
plate D, as shown by Figure 4 of the drawings, for the purpose of manipulating
the fastening-screws 63 for securing the plate b to the handle B. The slot in
the plate D is narrower than the slot in the handle proper and of sufficient width
only to receive the saw-blade proper. The lower ends d, d, of said plate D
are curved rearwardly and upwardly to form a catch for locking the blade in
position.
A locking device E embodies the metallic plate, having a slot e therein, said
slot being cut in said plate transversely with relation to the handle. A down-
wardly projecting lip el forms a convenient finger-grip for the manipulation of
the locking plate.
A longitudinal projection from the sliding plate E is provided with a down-
wardly-extending lip e³, said lip being adapted to engage the upturned lower
ends of the plate D. A screw F is threaded into the lower portion of the
handle, and upon the neck of said screw the locking-plate is adapted to slide.
In the operation of the device, the saw-blade is entered in the slot of the
plate D, the wings being below said plate and the whole brought in line with
the slot C. It is then pushed upward in said slot until it reaches the upper end.
thereof. The locking-catch E is then slipped into position, effectually locking
the blade in position and preventing accidental displacement thereof. The
plate D, being of resilient metal, admits of its lower part d¹ being forced away
from the handle to clear the flanges a during the operation of inserting the saw-
blade, and the part d' will spring back under the lower ends of the flanges after
the saw is inserted, as shown by Figure 1 of the drawings. To remove the
blade, the catch is slipped out of engagement with the curved ends d¹d of the
plate D and said curved ends similarly raised to clear the wings of the blade.
The blade may then be easily slipped out from the slot.
It is obvious that the plate 1 may be made of spring-steel of sufficient
strength to act as its own catch. It is obvious, too, that a spring-catch may be
employed to lock the plate D in position in place of the sliding catch shown and
preferred. The upper end of the plate D, instead of being pivoted on a screw,
may be hinged to the metallic plate b.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. An improved handsaw, comprising a slotted handle having a bifurcated
plate fastened thereto, over the slotted portion, a bifurcated plate of resilient
metal secured to the said plate, and a removable blade having wings extended
therefrom for engagement between the two said plates and a rearward extension
engaging the slot in the handle, and means for retaining the saw-blade to prevent
accidental removal thereof, substantially as shown and described.
2. In a handsaw, the combination of a slotted handle having a bifurcated plate
over its slotted portion, a movable bifurcated plate of resilient metal connected
to an extension of the said bifurcated plate, whereby a
space is left
between the two said plates, and a saw-blade with a projected end
engaging the slot of the handle and having wings extended therefrom engag-
ing the space between the two plates, and a slide for closing the entrance to the
handle and preventing accidental removal of the saw-blade, substantially as shown
and described.
3. An improved handsaw, embodying a blade having wings fixed theron, a
slotted handle provided with a metallic bifurcated facing, a resilient metallic
plate pivoted thereto, said resilient plate being provided with a slot to receive
the saw-blade proper and with upturned curved ends, a sliding locking-plate pro-
vided with a slot through which a screw is passed for retaining it on the handle,

page_text: said locking-plate being provided with a downwardly-extended lip for engage-
ment with the upturned ends of the said resilient plate and with a projected
finger-grip for operating it, substantially as shown and described.
