JAR HOLDER‘
Andrew John Kriska, Cleveland, Ohio
Application April 21, 1937, Serial No. 138,091
2 Claims.
(Cl. 81-33)
My invention relates to jar holding devices and
in particular to that type of device which pro
vides an ef?cient and practical method for hold
ing jars ?rmly while caps or covers are screwed on
or off.
5
One object is to provide a device which is adapt
able to any size jar and has means therein where
by a positive clamping is secured by manipulating
a handle at one corner of the said device.
1O
Another object is to provide a structure which
may be manufactured at a minimum cost.
These and other objects and advantages may
be noted from the following speci?cation and its
accompanying illustrations, in which:
15
Fig. 1 is a perspective view of the device show
,ing the method of operation.
Fig. 2 is a top plan view, with the jar in sec
tion, showing the position of the device necessary
to tighten the cap or cover on the jar.
Fig. 3 is a side elevation of Fig. 2.
Fig. 4 is a top plan view similar to Fig. 2, but
showing the device in the position necessary for
removing the cap or cover from the jar.
Fig. 5 is an enlarged elevation of the operating
25
handle.
'
Fig. 6 is an enlarged view of the locking device
for securing the operating handle to the jar hold
ing device.
Referring again to the illustrations, a pair of
30 channel members of unequal length are pro
vided; the forward channel member l0 being
longer than the rear channel member II, both
having a longitudinal stiffening rib 50 as shown
in Figs. 1 and 3.
Long links I2 and I3 are pivotally secured to
35
the top and bottom ?anges Illa and Ila and I011
and Nb respectively of the channel members Ill
and II, above and below said members, by a
pivoting post I4 therethrough at the forward end
40 and by a pivoting operating handle post I5 at
the rear end of said long links I2 and I3 said
handle being secured by a lock washer I512; in
serted over the narrow portion I5b= at the lower
end of the handle post I5c.
Short links I6 and Il are pivotally secured
45
to the ?anges Illa and Ila and Illb and Nb‘ re
spectively at the opposite end of the channel
members l0 and II above and below said mem
bers by pivoting posts I8 and I9 respectively.
A plurality of strips or panels 20 and 2 I, having
50
a rough or uneven outer surface, such as cor
rugated rubber or the like, are secured to the
inner surfaces of the channel members Ill and II
respectively, by vulcanizing, riveting or the like.
The short link I6 terminates in a flanged end
55
I6a‘ with an aperture 22 therethrough; a short
sliding spring member 23 has a rearwardly pro~
jecting portion 23a. also with an aperture there
through; a pivot pin 24 is secured through the
aperture 22 in the ?anged end Ilia of the short
link I6, and the aperture in the projecting por
tion 23a of the sliding spring member 23, thus
securing the end of the sliding spring member
to the ?ange of the short link I6.
A long sliding spring member 25 is pivotally se
cured to the top surface of a toggle or cam lever
26 by a pivot pin 21, the toggle lever in turn being
pivotally secured by a pivot 28 to an angular
plate 29 mounted on the outer surface of the
channel member I0 and secured by rivets 29a or
the like.
The long sliding spring member 25 is shoul
dered on both edges at 25a, the short sliding
spring member 23 being superimposed over the
smaller portion 25b, thus formed, of the said long
sliding spring member.
A notch 3|] in the outer edge of the long sliding
spring member 25 adjacent to the shoulder 25a
retains therein one end of the spring 3| which
is superimposed over the smaller portion 25b of
the long sliding spring member 25 and the short
sliding spring member 23 mounted thereon, the
opposite end of the spring 3| being secured
around an outwardly projecting segment or por
tion 32 of the short sliding spring member 23.
Clamps 33 and 34 are rigidly secured to the
lower ?ange "lb of the channel member Ill and
provide a means whereby the jar holding device
may be secured to a table top 35.
In operation the device is secured to the table
top 35 by clamps 33 and 34, the operating han
dle I5 is moved to its normal position, directly
in line with the pivot post I4, the jar 36 is in
serted between the channel members II] and I I
and, when ?lled, the cap or cover is then placed
on the jar, the operating handle I5 is pushed to
the left until the jar is ?rmly gripped between
the channel members II] and II, the corrugated
rubber surfaces of the panels 20 and 2| retain
the jar securely therebetween and thus eliminate
any fear of slipping. The cap is then screwed
down'securelylon the threaded neck of the jar,
in the direction indicated by the arrows in Fig. 2.
The spring unit on the front channel member
IEI being in the position shown in Fig. 2, the slid
ing spring member 23 being in the open position
with the spring 3| expanded, thus creating a ten
sion which tends to cause a tighter grip on the
Jar.
2
2,127,301
To remove a cap or cover, the jar is placed as
before, but the operating handle I5 is drawn to
the left, the cam lever 26 is reversed as shown
in Fig. 4 and the jar is again held rigidly be~
tween the channel members l0 and II with the
pressure on the jar reversed to offset-the re
verse motion in removing the cap or cover, the
direction being indicated by_ the arrows in Fig. 4.
Thus in either action as illustrated by Figs. 2
and. 4 respectively, the harder the cap or cover
is turned on or off of the neck of the jar, the
tighter the jar 36 becomes wedged between the
channel members I0 and H.
I claim:
15
'
1. A jar holder comprising a pair of opposed
gripping members disposed at an angle to each
other, one member being ?xed and the other
shiftable lengthwise to effect a clamping action,
swinging links of ?xed length pivoted to opposite
ends of the respective members, a spring con
nected at one end to one of the links, and tend
ing to shift the link and the shiftable member in
one direction, and a toggle pivoted to the ?xed
UK
member and connected to the other end of the
spring.
10
2. A jar holder as in claim 1, the swinging
links comprising a pair thereof at the top and
bottom respectively of each end of the gripping
members.
