the guide finger being disposed directly above` the
blade and spaced therefrom, so that the blade
may be used in cutting Athe usual can top from
a can, thereby providing a can-opening tool ca
pable of removing various types of can closures.
In the form of the invention as shown by Fig.
3 of the drawings, the body portion of the opener
is indicated by the reference character 26 and
also embodies a pair of connected members
formed with cut-out portions which, when the
members are secured together, provide an open
ing for the arm 21 which is formed with an elon
gated opening 28 that accommodates the pivot
pin 29 that is supported on the body portion,
and extends across the opening. Thus it will be
seen that due to this construction, the arm 21
may be moved forwardly, and then returned to
the position as shown by Figs. 3, whereby the
leverage will be appreciably increased.
The body portion is formed with a wide curved
lip 29' which' is adapted to fit over one edge of
a bottle cap, the lip being of a length to extend
to the usual bead of a bottle, directly under the
cap, as shown by Fig. 3.V Teeth 30 are formed
I4 of the lifting arm 9 to grip the latter arm and
move same downwardly. This downward pres
sure forces .the body portion into close engage
ment with' one edge of the cap, while the lip I2
moves upwardly under the cap, prying the cap
from its position on the jar or bottle on which
it is located.
What is claimed is:
1. A jar cap remover comprising a body por
10 tion, one end of the body portion adapted to rest
on a jar cap, a transversely disposed lifting arm
pivotally connected with the body portion, one
end of said lifting arm adapted to engage under
a jar cap to be removed, a substantially vertical
15. arm having an elongated opening through
which the lifting arm extends, a link pivotally
connected with the body portion and to which
th'e substantially vertical arm is pivotally con
nected, a pressure arm pivotally mounted on the
20 body portion, a link connecting said pressure
arm and the link connected with the substan
tially vertical arm, whereby pressure directed to
the pressure arm operates to lift the cap-engag
ing end of the horizontal arm, and a coiled spring
directly above the lip 29’ and are adapted to bite 25 connected with the body portion and pivoted
link, said spring adapted to normally pull the
into the bottle cap to prevent slipping of the
tool, when pressure is directed to the arm 21
>in removing the cap.
The body portion is also formed with a de
pending ñnger 3| which has a. rearwardly curved
vertical arm upwardly.
2. A jar cap remover comprising a vertica
body portion, one end of the body portion adapt
ed to rest on a jar cap, a lifting arm having>
cap-engaging portion 32 adapted to lit directly
an elongatedopening, a pin extending from the
under one edge of the cap being removed.
A ch'ain indicated at 33', has connection with
the body portion 2E, near the upper end thereof,

opening adjustably connecting the body portion
and lifting arm, a cap-engaging lift Vformed on

portion, is a blade 34 and a guide finger 35 di 40 connecting the lifting armV and` arm `through
which the lifting arm extends, `a pressure arm

these lugs 36 will operate to prevent twisting of 50 of the body portion, the lower end of the body
portion adapted to rest'on a jar cap being- re

ends, adapted to fit under the cap, means> for

portion, a pressure arm pivotally connected with'
the body portion below the handle thereof, and

because of this adjustment of the arm 9, the
means for exerting downward pressure on one

regardless of the size of cap being removed.
As the operating handle I6 of the device is

downward pressure will be directed to the arm
