Application June 28, 1937', Serial No. 150,876
3 Claims.
This invention relates to foot feed attachments
for sewing machines and has for an object to
(01. 112-239)
'
H for imparting movement to the needle bar [2.
A presser foot I3 is operated in the usual manner
A further object of the invention is to provide
by mechanism of the machine (not shown). The
presser foot is raised by the customary lever I4
so that goods may be placed under the presser
foot.
To permit the presser foot being raised higher
a high lift foot feed attachment which will not
than ordinarily by the conventional actuating
permit the needle to be pushed out of alignment,
bar I5 a bracket-like main frame I6 is provided
with a slot I1, best shown in Figure 4, to receive 10,
the actuating bar l5 and an actuating bar clamp
plate i8 is removably secured in position to secure
the main frame to the actuating bar by means
of a screw [9 passed through the plate and into
the main frame.
A Slot 20 is formed in the bottom of the main
frame to receive a compensator block 2| which is
provide a high lift mechanism which will permit
thick boot counters to be sewed as easily as thin
5 counters, and which will permit reverse seams
to be sewed in leather jackets and coats.
10 or material to lag, as the case may be thereby
preventing thread breaks.
A further object of the invention is to provide
a device of this character which may be readily
substituted for the conventional lift attachment
15 by unskilled persons in approximately one min
ute and without the use of tools.
A further object is to provide a device of this
character which will be formed of a few strong
simple and durable parts, which will be inexpen
20 sive to manufacture, and which will not easily
get out of order.
With the above and other objects in view the
invention consists of certain novel details of con
struction and combinations of parts hereinafter
fully described and claimed, it being understood
that various modi?cations may be resorted to
within the scope of the appended claims without
departing from the spirit or sacri?cing any of
the advantages of the invention.
In the accompanying drawing forming part of
30
this speci?cation,
Figure 1 is a fragmentary side elevation of a
sewing machine with a high lift foot feed applied
thereto and constructed in accordance with the
invention.
Figure 2 is an enlarged side elevation of the
attachment showing the compensator block in
normal position to permit the presser foot to
lift sufficiently to operate upon goods of a pre
40 determined thickness.
Figure 3 is a View similar to Figure 2 but show
ing the compensator block rotated through an
angle of 90 degrees to elevate the actuating rod
about $2 of an inch higher than when the block
45 is in the position shown in Figure 2 to permit the
machine operating upon goods of a greater thick
ness.
Figure 4 is a front elevation of the attachment
removed from the machine.
Figure 5 is a detail perspective view of the
50
compensator block.
Referring now to the drawing in which like
characters of reference designate similar parts
in the various views, In designates a conventional
55 type of sewing machine having an operating lever
substantially rectangular in contour and is
rounded at one corner as shown at 22 in Figure 3.
The block is provided with an opening 23 and 2O
a shaft 24 is passed through registering open
ings 25 in the main frame, and through the open
ing 23 of the block. The block is pinned to the
shaft to be moved as a unit therewith by a pin
26. A hand control wheel 2'! is ?xed to the shaft. 25
The compensator block is so mounted on the
shaft that the shaft is disposed nearer one end
of the block than the other end of the block. The
hand control wheel 2'! may be turned in one di
rection to dispose the block to extend with its
long median line parallel with the conventional
rock lever 28, as best shown in Figure 2, or may
be turned from this position through an angle of
90 degrees to dispose the long diameter of the
block perpendicular to- the rock lever 28, as best .
shown in Figure 3. In the latter position the
block will space the actuating bar I5 approxi
mately % of an inch higher from the rock lever
than in the former position so that the presser
foot will be raised to receive thick work such as
boot counters, leather jackets, coats and other
goods.
From the above description it is thought that
the construction and operation of the invention
will be fully understood without further explana
tion.
What is claimed is:
1.- In a sewing machine, the combination with
the presser foot actuating bar, of a member con
nected to the bar, a compensator block revolubly _
mounted on the member, said block having a
long longitudinal median line and a short trans
verse median line, a grip connected to the block
for manually turning the block to dispose the
same with its long median line extending either 55

‘ vertically or horizontally, and a driven lever for‘
actuating the presser foot engageable with the
block in either of its adjusted positions.

2. In a sewing machine, comprising the com
bination with the presser foot actuating bar, of
a bracket-like main frame removably secured to
the bar, a manually revoluble shaft carried by
the frame, there being a slot in the bottom of
the frame through which said shaft passes, a
‘10 compensator block of substantially rectangular
3. In a sewing machine, comprising the combi
nation with the presser foot actuating bar, of a
bracket-like main frame provided with a lateral
slot to receive the bar, a clamp plate on the frame
securing the frame to the bar, there being a slot
formed in the bottom of the frame, a compen
sator block of substantially rectangular contour
received in said slot having a long longitudinal
median line and a short transverse median line,
a shaft revolubly mounted in the frame and ?xed
contour and rounded at one corner ?xed to the
to the block near one end of the block for ro
shaft in the slot, said shaft passing through said
tating the block through an angle of 90 degrees
to dispose selectively the long median line of the
block nearer one end of the block than the other
end of the block whereby the shaft may be ro
15 tated through an angle of 90 degrees to dispose
the block with its long median diameter selec
tively, horizontally or vertically, and a driven
lever for actuating the presser foot engageable
with the block in either of its adjusted positions.
block in horizontal or in vertical position, and a
driven lever for actuating the presser foot en
gageable with the block in either of its adjusted
positions.
