ADJUSTABLE . STRETCHER FRAME
William A. Davis, Chicago, Ill.
' Application March 11,
4 Claims.
This invention relates to a stretcher frame.
The construction herein described is particularly
adapted for holding a piece of cloth in position
for embroidery work and other needle craft, but
5 the invention may be adapted as well to other
uses.
An object of the invention is to provide an ad
justable stretcher frame which will support a
cloth on all sides in the same plane, thus elimi
10 nating wrinkles and curvature over the surface
of the cloth. Another object is to provide an ad
justable stretcher frame which will permit the
cloth to be fastened at points on a side of the
frame and which will yet permit stretching of
the cloth between the points at which‘ it is
fastened.
_
In common constructions of adjustable frames
two members are adjustably secured on top of two
other members. Obviously, the tops of two mem
{v0 bers are in‘a plane different from that of the
tops of the other two, and when the cloth is ‘at
tached to the tops of all members wrinkles and
unevenness result. Also, as the cloth when pulled
taut has a tendency to assume a single plane, it
is likely to be pulled loose at points where it is
fastened to the under members. These and other
objections are overcome by the construction here
in disclosed. Further objects and advantages of
my invention will become apparent as the speci
?cation proceeds.
‘
Figure 1 is a plan view of an embodiment of the
invention with the structure completely as

mit sufficient adjustment of the frame for prac
tical purposes.
The cross members B may consist of wooden
cross strips l2 as clearly illustrated in Figures
3 and 4, and slidable wooden blocks l4 more
clearly shown in Figure 7. The cross strips I2
are centrally slotted throughout their length ex
cept ‘for the middle portion l3. Middle portion
I3 is raised above the main level of the strip and
its thickness exceeds that of the slotted portions. '
of the strip by the thickness of the side mem
bers A.
‘
.
The blocks l4, which may be made of wood,
have slotted sides and have I-shaped cross sec
tions. The thickness of the upper portion I5,
above the slot, is the same as that of the side
members A, the slots l6 and l‘! are of such size
as to admit an edge of cross strip ‘l2, and the
center portion 18 is of such width as to be con
veniently received within slots l9 or, 20 of the
cross strips 12. Thus, the blocks l4 may be slid‘
ably mounted on the cross strips, the center por
tion l8 of the blocks sliding in slots l9 and 20
of the cross‘ strips, and the edges of the cross
strips sliding in slots [6 and‘ H of the block.
Strips l2 may be adapted‘ to receive any desired
number of blocks of suitable lengths.
‘
After the blocks have been slidably mounted
upon the cross strips, ?llers 2| are inserted in the
ends of the slots l9 and 20 and secured by cross _
pins 22. However, sufficient space is left for the
sliding of the blocks so that‘the blocks may be
sembled and showing a fragment of cloth to illus
moved endwise to allow side members A to be
trate how the cloth may be attached; Figure 2
placed between them, and preferably there should
35 a sectional view as seen from line 2 of Figure
1; Figure 3 a view in elevation of a cross mem
be left additional sliding space as‘shown in Fig
ures 1 and 2. If desired the raised portion l3 of

a cross member‘ with the blocks omitted; Figure
5 a plan View of a side member; Figure 6 a view
40 in elevation of a side ‘member; and Figure 7 a
View in perspective of one of the blocks.
In the illustration given, A denotes the side
members, and B denotes the cross members. A’
and A2 are left and right side members respec
4 CR
tively, and B’ and B2 are top and bottom cross
members B may be omitted and this part. of the
strip slotted to accommodate slidable blocks just
members respectively.
The construction of side members A is more
as are the end portions.
‘
‘
Side members A are fastened to cross members
B by bolts 23 extending through the slots of each
member and tightened by wing nuts 24 on the
under side of the frame. ‘ The ‘side members may
be placed with their edges abutting the ends of
middle portion l3 of the cross members, as mem- .
ber A2 is shown in Figures 1 and 2; or, if a larger
frame is desired, one or more blocks on members
B may be pushed inwardly until they abut
against portion l3, and side members A then
fastened with their edges abutting the outer ends 50
of these blocks, as member A’ is shown in Fig
clearly shown in Figures 5 and 6 of the drawings.

having slots l0 and H. Slots l0 and II may be
extended toward each other or entirely joined as

shown with a middle unslotted portion mainly
55 because this lends greater strength and will per

members by any suitable means such as by the
use of thumb tacks 26. In the illustration given
the cloth is shown attached near the outer edges
of the side members, but it may be attached near
the inner edges as well.
In the use of this stretching frame the side
members are ?rst attached to the cross mem
bers at such an adjustment as most nearly ac
commodates the size of the cloth to be mounted.
10 Adjustment of the distance between cross mem
bers B is made by sliding bolts 23 in slots l0
and H; this adjustment is limited only by the
length of these slots. Adjustment of the dis
tance between side members A is made as pre
15 viously explained by inserting one or more blocks
between the side members as they are mounted;
this adjustment is limited to intervals corre
sponding to the length of the blocks. However,
adjustment may be made for cloth of various
20 widths by selecting the number of blocks which
most nearly gives the desired spacing and then
attaching the cloth either at the outer edge or
the inner edge of the side members as happens
to be convenient.
After the cloth is attached at all sides, the
25
frame may again be adjusted for stretching the
cloth taut. This is done by loosening wing nuts
24 and moving one or both side members A out
wardly to take up some of the additional space
30 left between the slidable blocks, the bolts 23 be
ing allowed to slide along slots [9 and 20 until
the cloth is drawn su?iciently taut, and again
tightening nuts 24 to secure the members in at
tachment. After the cloth has been used for
some time in this position it has a tendency to
stretch and again become loose. To remedy this
the frame may be adjusted as before, or, if all
additional space is taken up, it may be necessary
to slide added blocks between the side members.
The edges of the cloth or material may be
40
tacked to the blocks within the side members as
well as to central portions 13. In this construc
tion, when the side members are moved apart to
stretch the cloth, the blocks within the side
members to which the cloth is attached will also
45 slide outwardly. This allows stretching of the
cloth between points of attachment at the edges.
The tops of the middle portions I3, the tops of
blocks I4, and the tops of side members A, are
all of an even level. This causes cloth having
50 its edges attached to the tops of these various
members to be suspended at points in one plane
only. Such a mounting is highly desirable in
that it eliminates much wrinkling and uneven
55
ness in the cloth.
In the form of the invention herein described
only the cross members are equipped with slid
able blocks, but it should be understood that the
side members may also be equipped in a similar
fashion. Also numerous other changes may be
60 made in the construction without departing from
the spirit of the invention. The foregoing de
tailed description has been given for clearness
of understanding only, and no unnecessary limi
tations should be understood therefrom, but the
appended claims should be construed as broad
ly as permissible, in view of the prior art.
