(Cl. 2>42-—130)
This invention relates to pin boards of that
type shown, for example, in Patents 1,794,775, of
March 3, 1931 and 1,895,416 of January 24, 1933.
The handling and stacking of boards of this
' type has always been a problem. When carrying
a board ?lled with bobbins or the like the oper
ator usually has grasped one end of the frame
of the pin board and held the board suspended.
The weight of the bobbins has caused the pins on
10. the board to incline downwardly toward their
free ends with thelresult that the bobbins fre
quently would slip off of the pin.
A further di?icultyhas been found in the stack
ing of the pin boards.’ Generally the pin boards
15'. have been placed‘ in superimposed relation, each
board resting upon“ the bobbins ‘ on the next
adjoining board thereunder. Aside from the fact
that it has been ‘difficult to stack any number of
pin boards in this manner, the weight of the load
on the bobbins has injured them seriously and
this has been particularly true where the bobbins
have been formed with centralprotuberances or
bosses. For the purpose of overcoming ‘these
objectionable features, various means have been
adopted but without producing satisfactory re
sults. For example pin boards have been made
with continuous rods extending therearound
above the pins and joined to the sides of the.
board by connecting posts or the like. These
rods or rails, made integral with the pin boards,
have been objectionable, however, because when
the pin boards are stacked one upon the other,
they are not held against lateral displacement
and easily drop out of proper positions. Fur
thermore the rails, by extending continuously
about the boards, interfere with the movements
of the operator when placing the bobbins on or
removing them from the pin.
An object of the present invention is to pro
vide a pin board with simple but e?icient means
constituting both a handle and a stacking ele
ment whereby the pin board, while loaded, can
be carried at a properly inclined position to pre
vent the bobbins from slipping off of the pins
and whereby, when the pin boards are stacked
one upon the other, they will be held properly
centered relative to each other and cannot slip
in any direction so as to become accidentally
With the foregoing and other objects in view
which will appear as the description proceeds,
the invention consists of certain novel details of
construction and combinations of parts herein
after'more fully described and pointed out in
55 the claims, it being understood that changes
may-be made in the construction and arrange
ment of parts without departing from the spirit
of the invention as claimed.
In the accompanying drawing the preferred
form of the invention has been shown.
In said drawing
Figure 1 is a plan view of a pin board having
the present improvements.
Figure 2 is a side elevation thereof.
Figure 3 is a side elevation on a reduced scale
showing how the pin board can be carried with
the pins inclined upwardly so that the bobbins
will not slip off of them accidentally.
Figure 4 is a longitudinal section through one
end portion of two pin boards stacked one upon 15
the other.
Figure 5 is an end elevation of the stacked pin
Referring to the ?gures by' characters of refer
ence I designates the frame of the pin board 20
preferably made of a stiff rod, this frame having
its sides and ends connected by cross strips 2 to
which the upstanding pins 3 are joined.
The structure thus far described does not con
stitute any part of the present invention but has 25
already been disclosed for example in my patents
herein before referred to.
The present improvements include combined
handles and stacking devices arranged at the
ends of the frame. Each of these devices or
stacking handles is in the form of a stiff rod bent
to provide legs 4 the lower ends of which are
joined to the corner portions of the frame by
welding or in any other suitable manner, as
shown. The upper ends of these legs, which ex
tend well above the free ends of the pins 3, merge
into inverted U-shaped ears 5. The legs 4 are
arranged in pairs, one pair being located at each
end of the frame and the ears of each pair are
joined by a cross member 6. The ears provide
abrupt shoulders or abutments ‘I at the ends of
the cross members 6.
Each ear occupies the same plane as the legs 4
and cross member 6 and the maximum width
of each ear is substantially equal to the distance
between each side of frame I and the nearest
strip 2 parallel therewith. Thus‘ it will be seen
that when a pin board such as herein described
is lowered onto another pin board provided with
these improvements, the ears 5 of the lower 50
board will extend upwardly into the corner por
tions of the frame I thereabove and will ?t
snugly between the sides of the frame and. the
nearest longitudinal strips 2 and ?at against
member 6.
This has been shown clearly in
Figures 1 and 5. With the parts thus located,
the upper pin board I will not only rest ?rmly
_0n the cross members 6 of the lower pin board
but said upper pin board will be held against
lateral or longitudinal sliding movement relative
to the lower pin board because of the snug inter
?tting arrangement provided.
Obviously by constructing pin boards as de
scribed, a large number of them can be stacked
10 without danger of being shifted accidentally rel
ative to each other and, therefore, it becomes
unnecessary to provide separate shelves or other
supports for the superposed pin boards. Instead,
they can rest one above the other, the load
15 being transmitted from the legs of one pin board
to the legs of another with the result that the
bobbins, cones or the like mounted on the pins
3 will not be subjected to weight. On the con
trary ample space will be left above all of the
20 pins and the bobbins thereon for the free circu
lation of air, steam, etc. Thus the pin board
can be used successfully at all stagessduring the
progress of the bobbins or cones through the mill.
When it is desired to carry one of the pin
boards, it is merely necessary to hold it by one
of the stacking handles, the part 6 constituting
an e?icient grip as shown in Figure '3.
As this
held part is widely spaced from its frame I, the
pin board will be suspended at an angle as shown
30 in Figure 3 with the pins 3 inclined upwardly
in other boards when placed thereover.
the invention has been described as a pin board,
it is to be understood that the improvements are
equally adaptable for use in connection with
cone boards so that either bobbins or cones
can be properly stacked. The term “pin board”
is to be understood as intended to cover either
of these types of boards.
1. The combination with a pin board includ 10
ing a frame, and crossed strips carried thereby,
there being openings in the pin board formed by
the corner portions of the frame and the adja
cent crossed strips, of stacking handles rigidly
connected to and converging upwardly from op 15
posed portions of the frame, each of said stack
ing handles including a single length of mate
rial shaped to provide supporting legs, centering
projections overlying the corner openings in the
pin board, and a combined handle grip and pin 20
board-rest joining the projections, said projec
tions and handle grips constituting the sole con
nections above the frame between the legs, said
legs, projections and handle grip being in the
same plane, and said projections being posi
tioned and proportioned to rest flat against the 25
ends of a frame when engaged and centered
thereby and to extend throughout the width of
the openings in which they are seated.
2. The combination with a board including a 30
toward their free ends. Therefore there is no
danger of the bobbins or the like mounted on
frame, and upstanding holding devices on the
the pins from slippingoff of them accidentally.
the like, there being openings in the pin board,
Furthermore, as the member 6 does not extend
entirely around the pin board but only across
the ends thereof, the side portions of each pin
board are left free from obstructions and, there
fore, the operator can readily reach laterally
between these stacking handles so as to have
40 convenient access to the pins and the parts
It will be noted that the stacking handles are
inclined upwardly toward each other so that the
projecting centering ears 5 overlie the corner
- spaces of the pin board.
Thus they are properly
positioned for entering the corresponding spaces
What is claimed is:
frame for engagement with bobbins, cones or
of stacking elements connected {to opposed ends
of the frame, each of said elements including
legs secured at their lower ends to the frame, 35
and grips extending across the ends of the frame
and constituting the sole connections between
the legs above the frame, said grips being posi
tioned above the level of the holding devices,
there being centering means upstanding from
the grips in planes parallel with the ends of the
frame and overlying the openings in the pin
