Improvements in Lifting Dogs and the like.
I, HUGH RACEY PATRIARCHE, a Citizen of the United States, and residing at
No. 68, West Water Street, Milwaukee, in the County of Milwaukee, and State of
Wisconsin, U.S.A., Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
My invention has relation to improvements in hoisting and lowering devices
("lifting dogs") more especially intended for use on freight vessels for elevating
and lowering barrels, and the like.
The most commonly employed means for elevating barrels from and lowering
into the hold of a vessel is the provision of two slings suspended from a hoisting
rope, each of said slings carrying loosely two hooks, which hooks are adapted for
adjustment to the chimes of a barrel. This arrangement in practice has been
found to be open to serious objection, as for instance, in hauling up the slings after
the barrels have been detached, there is nothing to prevent said slings from becom-
ing tangled, which, when this occurs, and practice demonstrates that it almost
invariably does occur, entails considerable trouble, annoyance, and some loss of
time in untangling.
A further objection to the form of hoisting mechanism referred to resides in
the fact that three men are usually required to operate the mechanism, viz., one
man to operate the hoisting and lowering rope, and two men to handle the hooks,
in order to engage the same with the chimes of the barrel.
It is the primary object of my invention to overcome the above named disad-
vantages in a simple manner.
Another object resides in the provision of means for increasing or diminishing
the width of the frame for the purpose hereinafter specified.
A further object of the invention is the provision of means for raising or lower-
ing three barrels or kegs at one operation.
A still further object resides in the provision of a construction whereby a sling
carrying hooks of a certain style may be readily removed, and another sling
carrying hooks of a different form or size substituted therefor.
With the above, and other incidental, objects in view, the invention consists
of the devices and parts, or their equivalents, as hereinafter more fully pointed out.
In the accompanying drawing, Fig. 1 is a plan view of my invention.
Fig. 2 is an elevation of Fig. 1, with the longitudinal bars in section, showing in
dotted lines the hinged upper portion of the eye at the end of one of the bars
as raised.
Fig. 3 is a cross section of the device through the adjustable connecting arms or
bars.
Fig. 4 is a detail of one end of one of the longitudinal arms.
Fig. is a cross section through the overlapping adjustable bars, and
Fig. 6 is a plan view, on a reduced scale, of the construction adapted for elevat-
ing or lowering three barrels, kegs, or the like, at one operation."
Referring to the drawing, the numerals 7-7 indicate slings, each consisting of
a rope arranged in ordinary loop form. Each of these slings carries two hooks
TD 077

page_text: 8-8, which are of the ordinary form of hooks used in this class of devices, the
shank of each book being advisably provided with an eye through which the
rope forming the sling loosely passes. To the upper portions of the slings is
connected the lower end of a hoisting and lowering rope 9, the opposite end of
said rope being advisably connected to a windlass, or other suitable winding
mechanism (not shown.)
My improvements consist of a frame to which the slings are connected, said
frame consisting of two arms, and a connecting cross member. The arms are
indicated by the numerals 10-10'. These arms are shown as of a concave-convex
form in cross section, with the cavities uppermost, thereby forming grooves 11-11.
The opposite end of each arm is provided with a projecting lug 12, and to this lug
is hinged a half circular strap 13. Extending upwardly from the outer edge of
each strap is a plate 14, which plate forms a guard, and prevents the eyed portion
of the hook from slipping over on to the longitudinal arm of the frame. The
unhinged end of each curved strap 13 has pivoted thereto a latch 15, said latch
when the curved strap is in normal position, adapted to be turned so as to enter
the slot or bifurcated end of a projecting catch 16, the head of the latch passing
beneath said catch, and thereby holding the curved strap 13 locked, until the
latch is turned upwardly out of engagement with the slot of the catch 16. The
free end of a flat spring 17 bears on the latch, and the tension of this spring is
sufficient to hold the latch in engaging position, until said latch is turned upwardly
on its pivot by force applied directly thereto. The hinged strap 13 is also prefer-
ably provided at its unhinged end with a depending lug 18 which is adapted to pass
into a slot 19 of the bifurcated catch 16, when said hinged strap is turned down-
wardly to closed position, the said lug 18 thereby serving to steady the hinged
strap in said closed position.
The transverse connecting member for the arms consists of two parts, viz., a bar 20
extending from the arm 10, and provided throughout its length with a series of
openings 21, and a bar 22 extending from the arm 10', The portion 20 as will
be seen from the drawing overlaps the other portion 22 of the connecting member.
The bur 20 is provided at its extremity with a rigid collar 23, which loosely sur-
rounds the bar 22, and said bar 22 in turn is provided at its extremity with a
rigid collar 24, which loosely surrounds the bar 20. Pivoted between lugs pro-
jecting from one end of this collar 24 is a latch 25 said latch provided at or near its
free end with a depending dog or finger 26. The latch when turned down on its
pivot is adapted to extend over the upper side of the collar 24, and this upper side
of suid collar is provided with an opening 27, said opening adapted to be brought
into register with any of the openings 21 of the bar 20. When the latch is turned
down on its pivot, as just explained the depending dog or finger thereof is adapted
to engage the registering opening in the collar 24 and in the bar 20, and also
pass into an opening in har 22, and finally seat itself in a socket in the bottom of
collar 24. By this provision the two parts of the adjustable connecting memper
are locked in adjusted position. On the under side of the collar 24 is secured a
spring 28, the free end of said spring bearing against the pivoted end of the
latch, and thereby holding said latch firmly in locking position.
In Figure 6 of the drawing I show a modification of the invention to adapt it
for elevating or lowering three barrels, kegs, or the like, at one operation. This
consists in providing an extra arın 10%, constructed exactly similar to the
arms 10-10. The arm 10% is connected to the adjacent arm 10¹ by a similar
adjustable connecting member to that which connects the arms 10-10¹, and con-
sisting of two bars designated by the numerals 20 & 22. The connecting bar 20¹
is similar to the connecting bar 20, and the connecting bar 221 to the connecting
bar 22. The same form of collars 23 & 24 are employed, and the same form of
latch 25.
Figures 2&3 show the relation of the slings with references to the frame.
From these figures it will be seen that the lower portions of the slings pass
through the eyes provided at the ends of the arms and are seated in the grooves 11.

page_text: In applying my improved device, a man grasps either of the arms, or the
transverse connecting member, and arranges said arms over two adjacent barrels.
Two of the hooks are then made to engage the chimes of the barrels at corres-
ponding ends of said barrels, and then the two other hooks are made to engage
the chimes of the opposite ends of the barrel; or where the device shown in
Figure 6 is employed, the two hooks of the third arm 10% are made to engage
the chimes at the opposite ends of the third barrel or keg. The device is now
properly connected, so that the barrels may be lowered into the hold of the vessel
or elevated from the hold as the case may be. This is accomplished by unwinding
or winding up the rope 9, in accordance with whether it is desired to lower or
elevate the barrels. In case the distance between two of the arms is not such
as to permit said arms to extend properly along the lengths of the barrels, this
space may be readily adjusted so as to be increased or decreased, by merely dis-
engaging the latch 25, and adjusting the arms closer together or farther apart,
as required, the latch 25 being made to again engage, when the proper adjustment
is obtained. By this means, it will be obvious that the distance between the
arms may be readily regulated, in order to adapt said arms to fit adjacent barrels,
no matter what the diameter of said barrels may be. The two collars 23 and 24
of the two-part adjustable connecting member prevent separation of said parts of
the connecting member, and collar 24 also forms, in connection with the latch,
and the openings in the part 20, a means for locking the two-part adjustable
connecting member in adjusted position.
The grooves 11 in the arms hold the two slings entirely separate, and thereby
effectually prevent said slings from tangling and twisting. The provision of
the frame work consisting of the arms and the transverse connecting member,
also provides a single frame of such character as to enable one man to handle and
properly adjust all the hooks, in the manner herein before fully pointed out.
The provision of the hinged straps 13 at the ends of the arms, which when
turned downwardly form, in connection with the concave formation of the arm,
a complete eye or circle, makes it possible to readily remove one sling, when
desired, and substitute another sling therefor having hooks of a different form
or size mounted thereon. It will be understood that the slings usually employed
in devices of this class are continuous slings, and a number of these slings are
provided having different forms of hooks thereon. My construction, therefore,
presents an advantage in this respect, in thus providing for readily removing one
sling and substituting another.
While I prefer to employ the two arms 10-10¹ with the transverse connecting
member, yet I do not wish to be under-stood as limiting myself thereto, inasmuch
as two arms of the construction, or substantially the construction, shown, aud
adapted to be used in connection with the slings as described, or substantially
as described, and without the provision of the transverse connecting member, I
consider within the spirit and scope of my invention. I also desire to be under-
stood as claiming merely a single arm of the construction, or substantially the
construction described, as comprehended by my invention.
