COMPLETE SPECIFICATION.
Improvements in Buckles.
I EDMOND BURKE KNAPP, of San Jacinto, in the County of San Diego and State
of California, United States of America gentleman, 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 following statement:-
The invention relates to improvements in buckles. The object of the present inven-
tion is to improve and simplify the construction of buckles and render them more
durable, reliable and easily operated.
The invention consists in the construction and novel combination and arrangement
of parts bereinafter fully described, illustrated in the accompanying drawings, and
pointed out in the claims hereto appended.
In the drawings Fig. 1 is a perspective view of the improved buckle showing it
applied to a trace. Fig. 2 is a similar view of the buckle itself. Fig. 3 is a detail
view of the cam-lever. Fig. 4 is a perspective view showing the buckle applied to an
ordinary strap.
Referring to the accompanying drawings by letter, A designates a buckle having
horizontal side bars a which are designed to have connected to them a back-strap B
and a girth C. The side bars a are connected at their rear ends by a transverse bar a³,
to which is secured the forward end of a trace D. At the back of the buckle A over
the transverse har a', is a loop a which serves to retain the free end of a strap E and
at its front end the buckle is provided with two loops a' which are arranged parallel
and have their sides forming grooves a* or recesses, in the bottom of which is journaled
a cam-lever F, that bears against the under side of the strap E and forces the latter
against the bars which form the tops of the loop a². These bars are arranged a short
distance apart to enable the strap to be bulged up between them. whereby the strap
will be securely held and enabled to withstand all the strains incident to its use without
slipping. The cam-lever F consists of a thin flat handle and a round bar f' secured
thereto and provided with journals arranged eccentrically near its lower edge, whereby
when the free end of the lever is forced upward under the buckle the upper portion of
the bar which lies above the journals is pressed against the strap.
The strap E is designed to be connected to a hame; but the buckle A may be
attached to an ordinary strap, as illustrated in Fig. 4 and in this case the strap is
attached to the transverse bar and its free end is secured similarly to the strap E.
By varying the size of the cam-lever straps of different thickness may be used in
the same buckle, which permits the levers to be readily changed and to prevent the
strap slipping from the surface of the lever engaging the strap it may be milled,
corrugated or similarly roughened.
From the foregoing description and the accompanying drawings the construction,
operation and advantages of the invention will readily be understood.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
1. A bnckle provided at its forward end with the two loops arranged parallel and
having their sides forming grooves and a cam-lever journaled in said grooves,
tially as described.
substan-
2. A buckle comprising the side bars, the transverse bar arranged at the rear end
of the side bars, the parallel loops forming grooves and the cam-lever, substantially as
described.

page_text: 3. A buckle comprising the side bars, the transverse bar connecting the rear ends
thereof, the loop arranged above the transverse bar, the parallel loops and the cam-
lever journaled between the parallel loops substantially as described.
4. A buckle comprising the side bars, the transverse bar connecting the rear ends
thereof, the loop arranged above the transverse bar, the parallel loops forming grooves
and the cam-lever having the bar and the eccentrically-arranged journals substantially
as described.
5. A buckle having the parallel loops a³ a³ forming the groove between them, one
end of the groove being closed, combined with the cam-lever journaled in the groove
and removably fitted in place, the journals of the cam resting on the closed bottom of
the groove as set forth.
