Improvements in Buckles.
I, ERNEST MARX, of Brooklyn, in the County of Kings and State of New Yorks
United States of America, Gentleman, do hereby declare the nature of my invention
for IMPROVEMENTS IN BUCKLES, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My present invention relates to improvements in that class of buckles employing a
frame having points formed integral with, or rigidly fastened thereto in the plane of
the frame, and a movable guard or frame sliding on the main frame and serving to
force the fabric into engagement with the points or cause the release of the same as
the case may be.
In the practical manufacture of buckles such as above described, the necessity of
compensating for, or overcoming any spring in the metal has become apparent, as well
as the great desirability of giving the frame the greatest possible strength and, there-
fore, it is the object of my invention to produce a buckle at the lowest cost and least
possible number of parts which shall combine the maximum strength with the greatest
certainty and ease of operation, all as will be hereinafter described and pointed out
particularly in the claims at the end of this specification.
Referring to the accompanying drawings:
Figure 1 is a side elevation of a buckle having a cross bar for limiting the movement
of the sliding frame.
Figure 2 is a similar view of a buckle without the cross bar but with inward
extensions of the frame for limiting the movement of the sliding frame.
Figure 3 is a perspective view of the sliding frame.
Figure 4 is an edge view of the same.
Figure
5 is a sectional view showing the method of attachment and
Figures 6, 7 and 8 show modifications of the buckle frame.
Like letters of reference in all the figures denote the same parts.
A indicates the frame of the buckle which I form preferably of a single piece of
metal or wire bent into shape around a central or sliding frame B, the ends a being
turned in parallel with each other in the plane of the buckle frame and in position
to enter apertures or perforations b in the frame B.
The parts are so proportioned, as that when the rectangular sliding frame is at one
extreme of its movement, the points pass way across the same but when at the other
extreme of its movement, they are entirely withdrawn from the central opening,
the extreme points being just within and protected by the perforations in the frame,
so as to firmly hold the engaging web, or release the same, said fabric or strap being
passed through the sliding frame and the portion to which the buckle is permanently
attached being passed around the horizontal bar of the buckle frame as shown in
figures 1 and 5 or connected to the ring or hook as shown in figures 7 and 8.
C
In figure i the sliding frame is limited in its outward movement by the cross bar
which is secured in apertures in the buckle frame at the proper point, but in the other
forms of buckle instead of perforating and weakening the frame for the reception of
the ends of the cross bar the buckle frame forms the stops, little inwardly extending
projections d being struck up on the inner surface of the side pieces of the frame
against which the sliding frame abuts and which as they do not remove any material
and are so very small, do not weaken the structure in the least, or else as shown
in figures 6, 7 and 8 the central portion of the frame is formed into a hook i or
a ring k for the attachment of the end of the fabric, in which instances the inwardly
extending portions of the buckle frame constitute the stops for the sliding frame
which then moves clear across the rectangular portion of the buckle frame.
The said rectangular sliding frame B is preferably formed of a section of concavo-
convex wire, bent into shape, with the concavity outward forming channels for the

page_text: side pieces of the buckle frame, but it is obvious, that it may be struck up in any
well known manner.
As before mentioned, the buckle frame is bent into shape around the rectangular
frame, but it is found that if the ends of the sliding frame are united, as has heretofore
been usual, thereby forming an inflexible and rigid frame, before the buckle frame is
bent around the same, the side pieces of the buckle frame will spring back or away
froin the sliding framo leaving the latter loose and of course increasing the danger of
the accidental escape of the engaging strap as well as forming a loose and undesirable
buckle; which defect I overcome by forming the abutting ends of the sliding frame
V-shaped thereby preventing any independent lateral movement and leaving said
ends. otherwise unconfined, by which construction, it is found that there is sufficient
elasticity in the sliding frame to allow for the spring of the buckle frame, causing
the frame to fit tightly and work smoothly at all times, although requiring a
positive movement to release the strap engaged by the points.
In figure 6 the tongue is shown straight out or in the plane of the buckle
frame and in figure 7 the same is shown bent into hook form, while in figure 8
the wire or metal of the frame is simply crossed and formed into a ring or loop.
The buckle as thus constructed it will be seen consists of. but two parts easily
fitted together and capable of being produced with great rapidity by proper special
imachinery, no hand work being necessary to fit or join any delicate or complicated
parts.
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: f.
1. In a buckle, such as herein described, the combination with the buckle frame
having the inwardly projecting points, of the sliding frame mounted on the buckle
frame and the stops formed by the buckle frame for limiting the movement of the
sliding frame substantially as described.
2. In a buckle, such as herein described, the combination with the buckle frame
having the inwardly projecting points, of the sliding frame mounted on the buckle
frame and the inwardly extending projections of the buckle frame for limiting the
movement of the sliding frame; substantially as described.
3. In a buckle, such as herein described, the combination with the buckle
frame formed of a single piece of metal with the extremities bent inward, the
rectangular sliding frame 'formed of a single piece and mounted on the buckle
frame and having the perforations for the points and the inwardly extending pro-
jections struck up on the inside of the buckle frame for 'limiting the movement of
the sliding fraine; substantially as described.
4. In a buckle such as herein described, the combination with the buckle frame
formed of a single piece of 'metal having the points formed thereon, of the sliding
frame formed of a single piece having the concavities embracing the side pieces of the
buckle frame and having its ends disconnected whereby it is capable of a limited
spring substantially as and for the purpose specified.
5. In a buckle such as 'herein described, the combination with the buckle frame
formed of a single piece of metal bent into shape with its ends turned inward and
forming engaging points, of the sliding frame around which the buckle frame is bent
formed of a single piece, with the ends cut V-shape and disconnected; substantially
as described.
