Improvements in or Additions to Drawing and like Pins.
I, ALFRED AUGUSTUS WOODWARD, of Vittoria Street, in the City of
Birmingham, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to fixing-down devices, known in commerce as pins, such as
drawing, drugget and paper fixing pins, consisting essentially of a spike, terminated
by a flat head or disc.
Now these said pins are difficult to remove or to lay hold of, in consequence of
their extreme flatness, which is a necessary property in their construction.
Now the object of my invention is to provide a means whereby the said pins are
capable of being laid hold of, and my improvements consist in providing or fitting
the said pins with a supplementary turn-down flap or handle, which, when the pin
is in use, lies flat with the head or disc thereof, but when the pin requires to be
removed, the said supplementary hinged part is turned up and taken hold of, and
by it, the said pin is removed.
In a further form of my invention, I joint the head to the spike.
In carrying out one form of my invention, I take an ordinary pin, with a head or
disc, and I joint to the opposite sides of the same, a turn-down semi-circular or
bridge-shaped lift or pull, which, when the pin is in use, comprehends a semi-circle
of the head, and lies flat and flush with it, but when the said pin requires to be
removed, then the flap is turned up, and laid hold of by the thumb and finger and
by it the pin is removed.
The joint is made by opposite pins or trunnions of the one part and knuckle
joints or bearings of the other part.
I propose that the pivot centres or joints carried at the two opposite sides of the
head should be made out of the metal of the said head, by being cut out by suitable
press tools.
As a further form of my invention, I may make the said lift or pull in the form
of an excentrically pivoted disc, preferably of the size of the head, and adapted to
lie flat and coincident with it when the pin is in use, but when the same requires to
be lifted, then the said disc is turned aside, and made to overhang a portion of the
boundary edge of the said head, thus admitting of the fingers being placed there-
under, and the pin lifted or prized thereby.
As a further form of my invention, I may make the head in two parts, and joiut
the same together after the manner of the wings of a butterfly, and to the
underside middle part of the said flap or winged head, the spike is connected or
jointed.
The spike may be double pronged or staple shaped, and the top of the said staple
shaped prong may form the centre upon which the half heads or discs turn.
Or the head or disc may be jointed excentrically, and at or near its boundary
edge to the shank of the spike, or the spike may carry a fixed head or part head,
with a turned down, flush and hinged flap, which, with the part head, makes a
complete head.
When the pin requires to be removed, turn up the hinged sectional part, and by
it, pull the pin from its stuck-in position.

Improvements in or Additions to Drawing and like Pins.
I, ALFRED AUGUSTUS WOODWARD, of Vittoria Street, 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 ascer-
tained in and by the following statement :-
My invention relates to improvements in or additions to drawing, drugget and
other like affixing pins for the holding down of drawing and other papers, carpets,
druggettings and the like, and for upholstery and like purposes, and has for its
object primarily, the providing of the said articles with a lifter, handle or pull-out,
which is taken hold of when the said pins are required to be taken or removed from
their positions when in use.
In ordinary pins, no pull-out means are provided, and in order to remove the
same, the thumb nail or a pen-knife blade is inserted under them and then the same
prized out.
By my invention, as hereinafter described, the lifter, which normally lies flush or
flat with the top of the head of the pin, is first raised, then taken hold of by the
thumb and a finger, a slight twist given to it and then the pin is pulled out of its
affixing position.
Figure 1 of the accompanying drawings represents in perspective, a drawing or
like pin provided with a jointed or turn-up and turn-down central lifter, pull-out or
handle in accordance with one form of my invention.
Figure 2 represents a topside view of the same, with the lifter in its normal
position, when the pin is in use.
Figure 3 is an end edge view of Figure 2, showing the pin affixing a sheet of
paper down upon a board.
Figure 4 represents the jointed lifter raised centrally and vertically above the
plane of the pin, and in a position suitable for the same to be taken hold of by a
thumb and finger for removal.
Figure 5 represents an end edge view of Figure 4, but with the pin, as in Figure 3,
fixing down a sheet of paper upon a board.
Figure 6 represents a front view of the pin Figure 5 removed from the board.
Figure 7 represents the blank of the lifter prior to the ends being turned up into
knuckle joints.
Figure 8 represents the head of the pin separately showing the pivot centres
of the same, which are made preferably solid with the metal of the said head.
Figure 9 represents an upholstery affixing-down pin.
The same letters of reference indicate corresponding parts in Figures 1 to 9 of
the accompanying drawings.
a is the head or disc top of the pin, having pivot or trunnion centres a¹,
formed from out of the metal of the same, and directed outwardly from the
edge at the two opposite sides. is a lifter, handle or pull-out, consisting
essentially of a semi-circular shaped loop of metal, following one half of the
boundary edge of the pin, and with the terminal ends 6', turned up into joints b*,
which take around and turn upon the opposite pivots a', of the head a, as joint
centres.
These said pivot centres, besides constituting the joint centres, also form the
connection between the lifter and the pin, the underside of which latter is provided
with a spike c.
When the pin is in use, the semi-circular lifter loop b, lies flat and flush with
the head by its own weight, but when the pin requires to be removed, then
raise the lifter b, upon the joint centres into a central position, and crossing the
top side of the head as a diameter. Then take hold of the lifter by the thumb and

slightly twisted.
In applying my invention to drugget, upholstery and like heavy-headed pins,
I make the lifter or pull-out part proportionately stronger or of thicker metal.
Figure 10 represents an edge view of a modified form of my invention.
Figure 11 is a topside view of the same.
In this arrangement, the joint 62, of the pull-out or lifter b, has levering
extensions 63, which come upon the surface, and prize the spike of the pin out when.
the said lifter is raised.
Figure 12 represents an edge view of a further form of my invention, and
Figure 13 is a plan of the same.
In this modified form of my invention, the lifter, pull-up or handle part is made.
out of the metal of the head, or to form a part of the head.
It will be observed that this pin has not a central pull, and therefore is not so:
convenient and efficient as the first described arrangement.
a is the primary part of the head, is the pull part thereof, jointed at the
opposite parts 2, to pivots a', of the primary head part a, and preferably made or
cut out of the same by press tools. c is the spike.
When the pin is required to be removed, turn the lifter or flap b, upwards upon
its joint as represented in Figure 12, and then bodily pull out the pin after first
twisting it.
Figure 14 represents an edge view and Figure 15 a plan of a wall pin, with the
central and hinged lifter part provided with a suspension hook.
is the head, the pull-out or lifter, the hook and c the spike.
Figure 16 represents a modified form of the pin Figures 1 to 9.
In this arrangement the lifter or pull-out is fitted within the edge of the body of
the pin, so as to give the same a more symmetrical figure.
a is the head of the pin, c the spike, the lifter lying within the gap a', of the
edge of the head, and with the joint ends 3, taking and turning about the pivots a',
as connectors and centres.
Figure 17 represents a still further form of my invention.
In this modification the sleeve joints are made from out of the body of the pin,.
and the trunnion joints from out of the ends of the lifter.
a is the head of the pin, c its spike, a' are she joints, raised from the metal
of the body, wherein the pivot ends 2, of the pull-out or lifter b, take and turn.
Figure 18 represents a modified form of Figures 12 and 13. Instead of employing
a single pull flap, I employ two.
Figure 19 represents a further modified form of Figures 12 and 13, with the
pull-up or flap part made to constitute the major portion of the head.
Figure 20 represents a top-side plan, and Figure 21 an edge view of a.
modification of the double pull or take-hold form of my invention.
care double spikes, connected by a bar c, to which the inner and joint ends a³, of*
half flaps a, constituting the head of the pin are jointed.
Normally, the said take-hold-of flaps fall flat after the insertion of the double-
spikes.
Figure 22 represents a still further form of my invention. In this form of pin,.
the same has a double head, the upper one excentrically mounted upon the lower
one, so as to be capable, when turned in one direction, to an extent overlapping a
part of the edge of the said lower part.
Figure 23 is a plan of the same and Figure 24, is an edge view, partly in section,.
of Figure 23.
a is the head, or lower disc of the pin, and a² is an upper turning disc or
head, excentrically pivoted at a³. c is the spike, made fast to the lower and under
part a.
By turning the upper part a³, into the position as represented in Figures 23.
and 24, its edge is made to overhang a part of the edge of the lower disc a.
In order to ensure the lying flat down and the standing up of the pull-outs or

page_text: lifters, the pivots may be made angular, so that the encircling joint, when turned
upon it, slightly opens out, and tends to follow the angular sides and to keep the
lifter in fixed positions.
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 :-
:-
First. In a drawing, drugget or other like affixing down pin, fitting or
providing the same with a hinged, jointed or turn-down and turn-up lifter,
handle or pull-out, substantially as and for the purpose as described and set forth
in Figures 1 to 21.
Secondly. In a drawing, drugget or other like affixing-down pin having a
lifter, pull-out or handle, jointing the said pull-out to the two opposite sides, or to
pivots located upon the two opposite sides, of the head of the pin, in manner and in
the ways substantially as and for the purpose as described and set forth in
Figures 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 14, 15, 16 and 17.
Thirdly. In a drawing, drugget or other like affixing down pin having a lifter,
pull-out or handle; making the said pull-out or lifter from out of, or forming a part
of, the head of the pin, in manner and in the ways substantially as and for the
purpose as described and set forth in Figures 12, 13, 18, 19, 20 and 21.
Fourthly. In drawing, and like pins, making the head in two parts, with the
one excentrically mounted and swivelling upon the other part, substantially as and
for the purpose as described and set forth in Figures 22, 23 and 24.
