COMPLETE SPECIFICATION.
Improved Combined Carpet-tack and Disk.
I, CHRISTIAN GOTTLOB TRIESLER, of 2522, Canton Avenue, in the City of Balti-
more, State of Maryland, and United States of America, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to an improved combined carpet-tack and disk. The
object of the invention is to provide means for use with carpet-tacks whereby first,
the carpet will be more securely held and with less strain and wear on the carpet,
and second, the tack may be more readily withdrawn and without injury to the
carpet when it is desired to take the carpet up.
The invention is illustrated in the accompanying drawing in which,―
Figure 1 shows two views of the improved disk for carpet-tacks.
Figure 2 is a section of same.
Figure 3 is a view showing the combined carpet-tack and improved disk applied
to a carpet and floor.
Figure 4 shows a modified form of disk for carpet-tacks.
Figure 5 is a view showing the modified form of disk and tack applied to a
carpet and floor.
Referring to Figures 1, 2 and 3, the letter, a, designates an ordinary carpet-tack,
and, B, a disk of suitable hard material, such as metal, used in connection with the
tack. The disk has a circular rim-edge, c, which bears down upon the carpet, a
raised teat-shaped center, d, on its upper side; a tack-hole, e, through said raised
center, and a cavity, f, on its lower side.
carpet.
The raised center and seat, d, is formed by punching upward from the lower side,
an operation that produces an up-curved formation, as at, g; the diameter of the
central raised seat for the tack-head is less than the said head, a¹, thus the edge
of the tack-head projects laterally around said raised seat, and renders it easy to
apply a tack-puller or claw under the tack-head, when it is desired to take up the
It will also be seen that when the tack, a, is driven downward through the hole, e,
in the disk and through the carpet into the floor, a broad area on the carpet
surrounding the tack is pressed by the rim-edge, c, of the metal disk, and thereby
the carpet will be more securely held and with less strain and wear to the carpet
than is possible where tacks and the ordinary leather discs are used.
Disks of suitable material having the features just described
use
for
with carpet-tacks may be of different shape from that shown in
Figures 1, 2 and 3; another form is shown in Figures 4 and 5.
Here the disk, B¹, is somewhat saucer-shaped and is applied to the carpet in
inverted position. The circular rim-edge, c', is down-pointing; around the raised
central tack-head seat, d, is the up-curved formation, g', and an annular depres-
sion, h; a circular upper rim, i, rounded in cross-section is between the said
depression, h, and rim-edge, c¹. On the under side is the cavity, f¹. In this case
the tack-head, a', projects laterally all around the raised seat and is protected or

page_text: guarded by the rim, i, so as to prevent straws or clothing catching in the head.
A suitable tack-puller or claw may be readily inserted under the tack-head.
The result and the operation of this latter form of disk is substantially like that
of the form first described.
It will be seen that by combining the improved disk with the tack, the latter
becomes more effective in holding the carpet then when used alone, because a
broader area of the carpet around the tack is pressed tightly to the floor; less
injury is done the carpet by the tack because the strain does not come on a few
threads but on a large number. Moreover, the improved disk enables the tack to
be withdrawn without injury to the carpet, because a tack-puller may readily
get hold of the tack-head. This is an important advantage.
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. The herein-described carpet-holder and tack-releaser, consisting of a disk
having a rim-edge to bear on the carpet, a raised central tack-head seat, and a tack-
hole through said raised center.
2. A disk having a surface to bear on the carpet, a raised center on its upper
side, a hole through said raised center, and a cavity on its lower side, in combina-
tion with a tack passed down through said hole with its head seated on said
raised center and the edge of the head projecting laterally therefrom.
