My invention relates to improvements in jar 1 to 4 of the drawing. The vertical and nar
lifters, and has for its objects to provide a lifter rower strips II are parallel to act as support for
including a positive and secure frame, having a

The lower ends‘ l2 of the bent down'strips H
are bent toward each other forming a ?ange 13
on each, which ?anges are provided with con-‘
ed, and also guided for opening and closing jaws
to grip the neck of the jars for which the lifter

of the spring coil 14 to be later more fully ex

plained. Slightly above the ends l2 of the strips

on either side of the strip H, thereby providing
convenient transverse handle, and vertical strong,

of the latter as will be explained in detail.
It is a further object of my lifter to provide
four such ?anges l5 on the frame 5.
The outer
vertical coil springs adjacent the inner face’ of edges of said ?anges l5 are bent inwardly at it,
the respective frame strips to make readily at ' as shown in Figs. 3 to 6, and the inner edges ll

ment of the new springs when fracture requires
it. Another object is to mount the upper por
20 tions of the sliding elements pivotally together,
and thereby require no other pivotal connection"
of parts,—a very desirable advantage, aslater
Other objects and advantages will be apparent,
26 from the following description and the accompa
nying drawing in which:—
Figure 1 is a side view showing the jaws engag-v
ing the neck of a jar;
Figure 2 is a side elevation of the lifter show
30 ing the jaws separated;
Figure 3 is a front elevation of the device;
Figure 4 is a vertical, longitudinal section’ of
the lifter taken in a plane indicated, ‘by the line
4-4 of Fig. 3;
Figure 5 is a transverse sectional view taken in
a plane indicated by 5-5 of Fig. 4;
Figure 6 is a fragmentary detail of the lower tip
of one of the frame strips, and portions broken
away, and
Figure 7 is a perspective view of a detachable
detail fastener for the tip ?ange.
The lifter shown and described in this speci
?cation comprises an upper frame device 5 which‘
is without ?exibility and is vquite rigid, the jaws
6 which act to engage the neck ‘I of the jar, be—
ing guided by mounting the jaw members 8 upon
said device 5 for relative'movement thereon, and
thereby movement of the jaws to and away from
each other, being accomplished and controlled.
The frame 5 comprises an integral metal. strip
of ?at material whose original form is longitudi
nal, having an intermediate broadened portion
Whose lateral edges 9 are, in manufacture, turned
upwardly and toward each other, to form the
strong tubular handle portion ID, as seen in Figs.
of the ?anges l5 are shaped oblique to the length
of the strips, so that the intervening space‘ be
tween such ‘edges ll very positively widens in an
upward direction. Such edges H are not in con
tact with the strip faces, but are open suf?ciently
to receive jaw members 8 into such inclined inner
spaces l8 which are su?iciently open to, not
only admit the members 8, but permit slight
spaces‘ l8.

Such inclined spaces l8 furnish the

the latter rising or falling by manual
The actuation of the jaw members depends in
my construction shown, by forming them of
strong wire separately, on opposite sides of the
jar to be lifted and carried.
To this end, either
member '8 is integral and comprises a loop have
ing parallel rods 8 slidable lengthwise of the cor
responding inclined spaces 18 within the flanges
l5 of the frame 5, the'upper ends of the mem 35
bers'B are bent toward the inner face of the ad
jacent strip H, and then joined by an integral
cross rod 59, while the lower ends are bent in- _
wardly and outwardly where they are integrally
joined by arcuate connections to form the grip 40
ping jaws 6; whereby raising members 8 in the
guides ‘56' tends to open the jaws E, and lower
ing them tends to force the jaws toward each
other to grip the neck 1 of the jar.
The various parts which comprise the jar lifter 45
are each completely formed in such a'manner
that subsequent to their assembly the formations
will serve to lock the parts together withoutfur-'
ther deforming of any of the parts. To this end
each ?ange l3 which is bent inwardly as shown in
Fig. 6 is provided with a pair of arcuate recesses vZ31
forming between them an ear 26. After the‘jaw
members 8 have been: inserted vin the guides
