COMPLETE SPECIFICATION.
An Improved Fastener for Securing Rugs, Carpets, and the like, to
Floors and other Surfaces.
I, SAMUEL BOGHOS DONCHIAN, residing at Number 75 Pearl Street, in the
City of Hartford, County of Hartford, and State of Connecticut, United States of
America, Merchant, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly hereinafter described and
ascertained in and by the following statement :-
My invention relates to the class of devices designed for use in securing a rug,
carpet or like article to a floor, and the object of my invention is to provide a device
of this class that shall be thin and compact so as not to cause an unevenness on the
rug by reason of a hump at the place where the fastening device is used, and that
shall at the same time securely hold the rug in place, and a further object is to
provide a device of this class that shall be strong enough to withstand the strains
which shall be brought upon it under the peculiar conditions of use.
To this end my invention consists in the details of the several parts making up
the device as a whole and in the combination of such parts as more particularly
hereinafter described and pointed out in the claims :
Referring to the drawings:
Figure 1 is a detail view in central section through the device showing it attached
to a rug or the like.
Figure 2 is a plan view of the same.
Figure 3 is a plan view of the split ring.
Figure 4 is a detail view on enlarged scale in central vertical section of the
device.
Figure 5 is a bottom view of the device.
Figure 6 is a detail top view of the base section of the fastener.
In the use of rugs on a highly polished floor it is desirable to provide some means
for preventing the rug from slipping. In order to produce a satisfactory device of
this class it is necessary that the device shall possess the qualities of not injuring
the
rug or floor to which it is secured, as this would be a serious objection, and at
the same time the device should be of such a thickness as not to produce an
unevenness on the rug at the points where it is secured. In my improved device
there is embodied a rug-fastener possessing all of these qualities as shown in the
accompanying drawings, in which the numeral 1 denotes a portion of a rug to which
is secured the stud section 2 of the fastener. This stud section is concaved on its
under portion and provided with lips or flanges in which are made holes 4 by
means of which the stud section is secured to the under side of a rug or the like.
A stud 5 extends from the under side of the stud section preferably from a point
at about the center, as shown in the drawings, this stud having formed therein
a groove 6.
The numeral 7 denotes the base section of the fastener in which are formed
holes 8 by means of which the base may be secured to a floor. A recess 9 is
formed in this base section in which is located a preferably flat split ring 10. This
ring is made of spring metal, and the opening therein is of a size to fit snugly in
the groove 6 of the stud 5. A central opening 11 extends through the base section
and is formed of a size to closely fit the stud 5 on opposite sides of the recess 9.
The base section 7 is made to conform to the shape of the concavity in the stud
section so as to lie closely therein, and a round spring is preferably used in the

page_text: recess 9, as greater strength can be secured in this form of spring with a given
thickness, and this construction of the spring, of the concaved stud section, and the
base section closely fitting therein provides an extremely thin device, while at the
same time possessing the necessary holding qualities. The split ring 10 is
preferably formed of a size to loosely fit within the recess 9.
The base section is secured to the floor as by means of very small wire nails or
the like, and this does not materially damage the floor as when they are removed the
comparatively small holes can be easily filled with wax and polished over, and the
thread used to secure the plate or stud section to the rug, as shown in the drawings,
projects on the under surface of the plate and prevents any marring of the floor
by the slight rubbing of the plate in use.
An important advantage of my improved device resides in the construction of
the stud to closely fit the central opening through the base section; this affords
means whereby the stud is securely held against any lateral strain which would
tend to loosen it from the grasp of the spring, these strains being continuously
exerted in the peculiar use of the device as by walking on the rug.
I am aware that various devices have been used in which a stud from one part
has been frictionally held within an opposite part, and I do not broadly claim such
a construction. In none of these prior devices has provision been made for the
close fitting of the engaging parts and for a secure holding of the stud against a
strain tending to upset it.
A material feature of my invention resides in providing
the base section with a stud socket above and below the spring member whereby
auy rocking action of one part on the other is effectually prevented and any
strain transversely of the stud prevented from prying or tilting the latter out of
engagement.
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:
In combination in a carpet fastener, a stud section provided with means for
attachment to the carpet, the concave under surface of said section having a
projecting stud, the stud having a lecking groove, a base section shaped to snugly
fit the concaved under surface of the upper section and having a central opening,
the walls of which closely fit about the stud at both its ends and having
recess for a split ring within the base section, and the split ring loosely fitted
within the recess and adapted to engage the stud at the groove, all substantially as
described.
