JAR TOP

1 Claim.
(Cl. 215-91)
to form a slide-way for the ?at pressure member
This invention relates to jar tops.
The principal object of this invention is the ‘I and to hold the clamp centrally upon the jarv
‘
provision of a jar top that may be easily placed top II.
In placing the device upon the jar 6, the slide

A further object of this invention is the pro
vision of a jar top that may be clamped upon
a Jar.
A further object of this invention is the pro
vision of a jar top that may be securedby means
10 of a clamp and a slidable wedge member coop
erating therewith.
-
With the foregoing and other objects in view
which will appear as the description proceeds,
the invention resides in the combination and ar
15 rangement of parts and in the details of con
struction hereinafter described and claimed, it
being understood that changes in the precise
embodiment of the invention herein disclosed,
can be made within the scope of what is claimed,
without departing from the spirit of the inven
tion.
The invention is illustrated'in the accompany
ing drawing, wherein:
Figure 1 is a top plan view of the jar top in
25 position upon the top of a jar.
Figure 2 is a side elevation, with parts broken
away, of the jar top in position upon a jar.
Figure 3 is a cross section taken on line 3-3
of Figure 1.
By referring to the drawing it will be seen that
there is provided a clamp I having down-turned
portions 2 and 3, the extreme ends 4 of which
are turned inwardly in order to ?t underneath
a peripheral flange 5 of a jar 6. It will be seen
35 that the down-‘turned portion 3 is relatively
shorter than the down-turned portion 2. By re
ferring to Figure 1 it will be seen that there is
positioned upon the clamp I a slidable wedge
member comprising a flat pressure member ‘I and
curved pressure member 8 comes in contact with
the down-turned portion 2. The clamp I is then
slid onto the jar top H, the outer edge I6 of the
?at pressure member 1 sliding alongan edge I‘I
,
of the. raised portion I3. The raised portion I2 [101
being slightly larger than the raised portion I3,
an extreme end I8 of the flat pressure member
‘I will be stopped by coming in contact with the
inner edge I4 of the raised portion I2. The
clamping means is thenlcompleted by sliding the
pressure members and connecting slide member
into- the slide-way between the raised portions I2
and I3. A tightening of the top I3 takes place
compressing the top ?rmly and evenly against a
rubber ring I9 positioned between the upper edge 20
of the jar 6 and the lower surface of the jar
top II.
_
By referring to Figure 1 it will be seen that
the jar top is shown in a clamped position. The
flat pressure member ‘I presses downwardly uopn 25
the jar top II while the extreme outer ends II]
of the curved pressure member 8 form compres
sion points so that the jar is ?rmly held under'
a three point compression.‘ It is obvious that 30
in removing the clamp from the jar top it is
necessary only to slide the pressure members ‘I
and 8 and connecting slide 9 back against the
down-turned end 2, thereby releasing the pres
35
sure and allowing the clamp to be slid o?.
What I claim is:
In a jar top, a. clamp for’ said top, relatively
short downwardly extending and inturned ends
on said clamp adapted to ?t underneath a pe
ripheral ?ange of a jar, one down-turned portion 40
a slightly curved pressure member 8. These pres
sure members ‘I and 8 are formed of one piece being relatively longer than the other, a curved
of material and spaced apart by a slide member pressure member and a flat pressure member
9 formed by cut-out portions, between'the ends together with a ,slide'member formed by cut
of the pressure members ‘I and 8, turned upwardly out portions between the ends of the pressure
members turned upwardly and inwardly to v?t 45
45 and inwardly so as to ?t loosely upon the clamp I.
By referring to Figure 3 it will be seen that the ' loosely upon the clamp, a pair of raised portions
on said top, one larger than the other, said
slightly curved pressure member 8 makes pres
sure contact at its extreme ends III with a jar top smaller raised portion adapted to allow the flat
I I. By referring again to Figure 1, it will be seen portion to slidepast it and the larger portion
that the jar top II is provided with raised por-’ adapted to form a stop for ther?at portion when 50‘
tions l2 and I3, the portion I3 being slightly it reaches the center of the jar top where it can
smaller than the portion I2. The raised portions be slid between the raised portions, substantially
I2 and I3 are spaced apart and have their inner as described.
