3 Claims. (Cl. 29-267)
The present invention relates to a portable manually
actuata'ble wholly mechanical-type hinge pintle dislodg
of construction and operation as more fully hereinafter
described and claimed, reference being had to the accom
panying drawing forming a part hereof, wherein like
numerals refer to like parts throughout, and in which:
FIGURE 1 is a view in perspective showing a frag
mentary portion of an upstanding tobacco containing
hogshead, the customarily used butt hinge and showing,
what is more important, the invention and how it is con

structed implement or device and which is expressly, but 10 structed and used;

Stated otherwise, the concept has to do with a simple,
practical and feasible tool-like device which provides an
easy-to-use pintle ejector, the same serving to speed up the
pintle removing step in a manner to expedite opening a
hogshead, the construction being such that it promotes a 20
saving in time and labor and ejects pins from the hinges
without damage to the surfaces of the hogshead sections
or the leaves of the hinges. Ordinarily, sectional hogs

The hinge means as an entity is denoted by the
numeral 6 and is a butt-type hinge construction, the
leaves thereof being denoted at 8 and 10‘ and fastened in
place at 12 on the component parts 14 and '15 of the
tobacco containing hogshead (not detailed). The ad
jacent ends of the leaves are provided with the usual

able hinge pin or pintle 18. The pin as usual is provided
with a head 19. These are all old or conventional parts.

Brie?y, a preferred embodiment of the invention is that

The handle functions not only for lifting, lowering and
positioning the base in coordinate relation, it contributes
to the other means for orienting the plunger. This plunger
comprises a reciprocable rod 34 which is shiftable in a
tubular sheath or cylinder 36 which is ?xed across the
lower edge portion of an adapter plate 38. This plate is
a simple ?at member having an end portion 40 superim

What is claimed as new is as follows:
1. A portable manually usable mechanical hinge pintle
dislodging and ejecting device comprising an elongated
heavy base channel-shaped in cross-section with the chan
nel open at ends thereof and with the median portions
of the respective longitudinal walls of said channel pro
vided with clearance notches, said notches registering
with each other, said channel being adapted to be placed
cooperating surfaces of said base, said plate being dis
posed in a plane at right angles to the lengthwise dimen
sion of said base, a cylindrical sheath ?xed across an
exterior of said plate, a plunger rod reciprocable in said
sheath, said plunger rod being in line with the clearance
notches and having an end portion projectible into at
least one of said notches in a manner to be lined up
with and to engage the pintle which is to be dislodged
and ejected from said pintle-connected knuckles, said
plunger rod having rack teeth exposed and accessible
over the leaves of a butt-hinge so that the said notches
register with the usual pintle-connected knuckles of said 40 through an opening provided therefor in said sheath, a
hinge, a handle disposed at right angles to a surface of
said base opposite to the channel portion of the base,
the axis of said handle being at right angles to the length
wise axis of said base, a plate disposed in a plane parallel
to the axis of said handle, said plate having marginal
portions joined to the handle and to adjacent cooper
ating surfaces of said base, a plunger slidingly mounted
on said plate, said plunger being in line with the afore
mentioned clearance notches and having an end portion 50
projectible into at least one of said notches when the
plunger is being used, said plunger having rack teeth, a
pinion gear parallel to and mounted for rotation on a
surface of the plate and in a position adjacent to the
pinion gear parallel to and mounted for rotation on a
surface of the plate, the teeth of said pinion gear be
ing aligned and in mesh with the teeth on said plunger
rod and a lever connected at one end to said gear and
located in a position for movement in a path toward
and from said handle.
