PROVISIONAL SPECIFICATION
Improvements in Drawing and other Affixing-down Pins.
I, FRANK HENRY SHAW, of The Universal Wood Working Company, Newhall
Hill, in the City of Birmingham, Manufacturer, do hereby declare the nature of
this invention to be as follows:-
-
This invention has relation to drawing, drugget and other holding or affixing
down pins, and has for its object, to provide such pins with inexpensive means
for removing them from their affixing positions.
The said invention consists in the employment in connection with a drawing
or like pin, of a lifting tab or flexible holder and in carrying out one form, i
propose to provide the heads of the pins with tabs of linen or other stout fabric,
suitably secured to the pin. Or instead of the holder attachment being in the
form of a tab or tail, it may be in the form of a disc so as to provide a flexible
finger hold all around the head.
To remove a pin so provided from a board or the like, it is simply necessary to
lay hold of the tab or pull-out attachment and lift it up, when the pin comes
away with it. When the pin is in use, say upon a drawing board, the tab or
attachment lies flat down against the said board, being flexible, does not present
any obstacles to the movement of drawing instruments, such as squares, over the
surface of the affixed sheet of paper.
The tabs may be formed from leather or other suitable material and the inner
end may be secured by closing it between the component blanks of a pin head
For instance, one

portion of the head, which is secured to the spike may be dished or sunken from
the underside and be provided with a pair or more of solid or hollow small teats.
Within this sinking a thin clamping disc is fitted, having holes corresponding to
the teats and in assembling the parts, the inner end of the tab, which may also
have small holes to go over the studs, is placed over the pin or spike and lodged
within the sinking. The clamping disc is then dropped in and both it and the
tab are locked by rivetting the studs, whose ends project to a slight extent
through the holes in the disc.
Or the top section of the head may have a short bush depending from its under-
side and surrounding the spike. A hole in the inner end of the tab is placed
over the bush which may be either expanded over directly onto the material or
be rivetted over onto the underside of a supplementary shell or clamping disc
which is also threaded onto the shank of the bush.
As another form of fixing-down pin, the lifting tab or pull may be made to
come upon the middle of the head, the top blank of which is pierced for the tab
to extend through. The central-pull tab thus provided may be made of a length
of fabric folded upon itself at the middle, and the ends may be clamped between
the two-closed together blanks and affixed, if necessary, by any additional means
0 of locking.
.
As a still further form of pin, instead of closing the inner end of the tab
between two discs or equivalent blanks, I may make the head of only one blank

end, is threaded and by the closing of the slit, the tab is secured.
The
As another modification the head is formed from a single blank and the spike
is affixed to the middle thereof, and the metal at the two opposite sides of the
pin slits are formed of a length about equal to the breadth of the tab.
said middle part is then arched so as to form a space through which the material
of the tab is threaded and afterwards the arched part is pressed back into the
plane of the head, the material is closed in between the metal, thereby securely
affixing the central pull tab. To prevent the cutting of the material of the tab,
a very thin liner may be interposed between it and the parts whereby it is clipped.
A central pull tab may also be secured by clamping the threaded-through
middle part between a pair of blanks.
The spikes may be plain or they may be wormed, and in the latter case the
pins are removed by rotating thence by means of the tabs instead of lifting them
out direct.

I, FRANK HENRY SHAW, of The Universal Wood Working Company, Newhall
Hill, in the City of Birmingham, Manufacturer, 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:-
This invention has relation to drawing, drugget and other holding or affixing
down pins, and has for its object, to provide such pins with inexpensive means
for removing them from their affixing positions.
The said invention consists in the employment in connection with a drawing
or like pin, of a lifting tab or flexible pull-out according to one form, I propose
to provide the heads of the pins with tabs of stout fabric or of leather or other
suitable material, suitably secured to the pin.
To remove a pin so provided from a board or the like, it is simply necessary
to lay hold of the tab or pull-out attachment and bodily lift the pin thereby.
When the pin is in use, say upon a drawing board, being flexible, does not pre-
sent any obstacles to the movement of drawing appliances, such as squares, over
the surface of the affixed sheet of paper.
Figure 1 of the accompanying drawings represents an elevation of a drawing.
pin provided with a flexible lifting tab or pull-out attachment in accordance with
one form of my invention.
Figure 2 represents a topside plan of the said pin.
Figure 3 is a transverse vertical section thereof, upon the dotted line x Figure 2,
showing how the tab attachment is secured to the head of the pin.
Figure 4 is an underside plan of this form of pin.
The same letters of reference indicate corresponding parts in the said Figures 1
to 4.
a is the head of the pin, provided with the usual spike b, and c is the pull-out
attachment, consisting of a length or strip of stout fabric, leather or other mate-
rial, the middle of which is passed onto the spike, whilst the ends c¹, are intro-
duced from underneath through slits or piercings a¹, in the head, and stand

page_text: above the top thereof, thus providing a pair of flexible tabs or finger-holds, the
attachment being secured in this position by closing the metal surrounding the
slits a¹, so as to nip and hold the material threaded through them. In order
to prevent cutting of the material it is proposed to swell or burr up the metal at
the nipping points a².
The spike may be plain or screwed, and be attached to the head by rivetting,
screwing or otherwise.
Figure 5 represents an elevation of another form of pin provided with a flexible
and central pull-out attachment in accordance with another form of my invention.
In this arrangement, the attachment is formed by a length of cord or strip of
material, whose ends are secured by closing them between the component blanks
or parts of a built-up head.
Figure 6 represents a topside plan of the said pin, and Figure 7 is a trans-
verse vertical section thereof upon the dotted line ¹, Figure 6.
Figure 8 represents an underside plan of the pin, and
Figure 9 shows the several component parts separately and in section, whilst
Figure 10 is a plan of one of the said component parts.
In the said Figures 5 to 10, a is the head of the pin, b the spike and c the
flexible pull-out attachment. The said head is made up of a top shell a', having
a central piercing a2, through which the attachment extends, a bottom shell a³,
and an enclosed clamping disc at, to which the inner ends c¹ of the length of cord
or material constituting the attachment are secured by first threading them col-
lectively through the central hole a and then respectively passing them into
the V-shaped slits a6 by the closing of which, the said ends c¹ are nipped and
made fast.
In assembling the parts, the clamping disc with the attachment connected to
it is placed inside the top shell of the head, and the lifting loop is passed through
the hole in the crown. The bottom disc carrying the pin is then dropped in and
the whole of the component elements are secured together by closing the edges a
of the top shell over the corresponding edges of the bottom shell, as represented
in Figure 7, and at the same time, the tongs a³, coming within the slits a³, are
further closed onto the ends of the cord.
Figure 11 represents a transverse vertical section and Figure 12 a topside plan
of a drawing or like pin provided with a central-pull attachment made from
5 cord or the like and secured in accordance with another form of my invention.
a is the head of the pin, b the spike and c the flexible attachment, consisting
of a length of cord or the like, whose ends c', are respectively passed through
separated holes a', in the head and then prevented from withdrawal by forming
knots at the extremities. These knotted ends are concealed and clamped or
O secured, if necessary, by a metal disc a³, which is threaded upon the spike up to
the underside of the head and connected thereto by closing the edges a of the
head over the corresponding edges a, of the threaded-on disc, which is or may
be also closed down onto the knotted ends as shown in Figure 11.
The clamping disc may be dispensed, with in which case the pin consists
5 simply of a head a, a spike and a pull-out attachment c (see Figure 13)
secured by knotting the ends .
As a further modification, which is represented in vertical section in Figure 14
and underside plan in Figure 15, the lifting attachment c is made in the form
of an endless loop of cord or other material one end of which is threaded through
0 a central hole a¹, in the head a, and then passed over a cross bar b¹, which
carries the spike b and is secured to the said head by closing its ends 62 between
turned-over edge parts a³.
As a still further form, the knotted ends c¹, of the cord attachment c, may (as
represented in Figure 16) lie within pockets or cupped sockets a³, fetched up from
55 the underside of the head a, and are clamped or secured by closing over or gather-
ing the walls of the said sockets upon the knotted ends.
In another arrangement, which is shown in plan in Figure 17 and transverse

page_text: section in Figure 18, the head a, of the pin is provided with a flexible pull-out
attachment c, in the form of a length or cord or the like which extends from
one edge. It is secured to the said head by threading the same in and out
through a series of holes a', a², a³, and prevented from becoming detached by
knotting the ends at c¹.
In all these forms instead of employing tied knots, we may use closed-on balls,
cleats or metal end attachments to prevent the disconnection of the cords.
Figure 19 represents another form of pin having a flexible tab or pull-out
attachment made from a strip of fabric, leather or the like extending from one
edge.
Figure 20 is a section of Figure 19 upon the dotted line 2 showing how the
tab is secured to the head.
Figure 21 shows an underside plan of the said pin.
a is the head, b the spike and c the flexible pull-out or tab attachment, the inner
end c¹, of which is secured by closing it between the component blanks of a pin head
made up of two or more parts, or any other convenient manner. For instance,
in the arrangement shown in the said Figures 19, 20 and 21, the top portion a¹ of
the head, which is secured to the spike b, may be dished or sunken from the
underside and be provided with a pair or more of solid (or hollow) small teats d.
Within this sinking a thin clamping disc at is fitted, having holes correspond-
ing to the teats and in assembling the parts, the inner end of the tab, which may
also have small holes to go over the studs, is placed over the pin or spike and
lodged within the sinking. The clamping disc is then dropped in and both it and
the tab are clamped by rivetting the studs, whose ends project to a slight extent
through the holes in the disc.
In the further modification represented in section in Figure 22, and underside
plan in Figure 23, the head a is also made up of two blanks a, a, between
which the inner end c, of the pull-out tab c is clamped, whilst the disc a², is
secured to the spike by closing the metal a², surrounding the central hole onto
the spike at 2, which may be notched or serrated to increase the hold upon it.
Instead if the pull-out attachment being in the form of a tab or tail, it may as
is represented in Figure 24, be in the form of a disc e so as to provide a flexible
finger hold all around the edge of the head a.
To prevent the cutting of the material of the tab, a very thin metal liner may
be interposed between it and the parts whereby it is clipped.
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: -
First:—In drawing and like affixing-down pins; providing the same with a
pull-out attachment in the form of a flexible tab or tabs, or a flexible loop, sub-
stantially as herein described, and also as set forth in the accompanying drawings.

page_text: as a³, substantially as herein described, and also as set forth in Figures 11, 12,
13, 16, 17 and 18 of the accompanying drawings.
Fifthly: A drawing or like affixing-down pin, provided with a flexible pull-
out attachment in the form of an endless loop of cord or material, one end of
which is threaded through a hole in the head of the pin and passed over a bar
or equivalent which carries the spike, and is secured to the said head substan-
tially as herein described and also as set forth in Figures 14 and 15 of the
accompanying drawings.
