Improvements in and relating to Pulley Blocks.
I, GEORGE JOHN. TILLING, Junior, of 83 High Street, Southampton, in the County
of Southampton, Rope Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to Pulley Blocks. My improved Blocks are so constructed
that they can be very readily engaged with, and as easily disengaged from eyebolts,
rings, and the like permanently closed fittings.
In pulley blocks now ordinarily made the metal binding of same generally
finishes at the top end of the block in the form of a hook or eye, if hook ended
some means are used to prevent the accidental disengagement of the hook from the
eyebolt, ring or eye into which the hook is passed, or if the binding finishes in the
form of an eye the connection of the block to any place or thing. must be made by
means of a hook, shackle, or similar fitting so as to admit of ready disconnection
of the block at will.
With the object of making it convenient to very readily connect a pulley block
to, and as readily to disconnect it from, either an eye, ring, or other similarly
closed fitting, and yet to secure the block from accidental disengagement from
such a fitting after engagement, I make the metal block .binding to finish at the
top of a block in the form of an eye or ring a part of which near the block being
hinged so that it (the hinged part) can be opened out or in, as desired at will;
but to secure the said hinged part of the block eye in the closed position, that is
so that it will form with the other part a complete eye or ring, I provide that it
shall be held in the closed position by means of a suitably disposed spring.
I may adopt various ways of fitting the said moveable part of the eye and the
spring, provided the moveable part is held securely in the closed position by a
spring.
To connect a block made according to my invention-as herein before described
to an eyebolt or other such like permanently closed fitting, the hinged part of
the block eye is hinged back, or hinged forward, as the case may be, that is as
arranged thus leaving a free opening in the eye temporarily transforming the
eye into a hook which can be readily inserted in an eyebolt, ring, or similarly
shaped fitting, the hinged part of block eye will then be folded into the closed
position, and is there held by. means of the aforesaid spring until it is again desired
to release the block when the hinged part is again manipulated in manner
aforesaid.

1, GEORGE JOHN TILLING, Junior, of 83 High Street, Southampton, in the County
of Hants, Rope Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
My invention relates to Pulley Blocks. My improved Blocks are so constructed
that they can be very readily engaged with, and as easily disengaged from eyebolts,
rings, and the like permanently closed fittings.
In pulley blocks now ordinarily made the metal binding of same generally
finishes at the top end of the block in the form of a hook or eye, if hook ended
some means are used to prevent the accidental disengagement of the hook from the
.eyebolt, ring, or eye into which the hook is passed, or if the binding finishes in the
form of an eye the connection of the block to any place or thing must be made by
means of a hook, shackle or similar fitting, so as to admit of the disconnection of
the block when required.
In the accompanying drawings I have shewn what I consider to be the best
means of carrying out my invention in which :-
Fig. 1 is a central sectional side view of a pulley block, fitted according to my
invention.
Fig. 2 a complete end view, taken at right angles to Fig. 1. Like letters
indicate corresponding parts throughout the drawings.
With the view of making it convenient to very readily connect a pulley block
to, and as readily to disconnect it from either an eye, ring, or other similarly closed
fitting, and yet to secure the block from accidental disengagement from such a
fitting after engagement, I make the eye or ring A of the metal binding B of the
block B in the form shewn in the drawings in which a part of the eye, in the
shape of a tongue C, is hinged on a pin D, passing through same and the adjacent
part of the eye or ring.
The hole E in the hinged part or tongue C, through which the pin D passes is
slotted as shewn for the purpose hereinafter described, and a recess is made at F to
take the pivotted end of the tongue C, and also a suitable coil spring G, a recess is
also provided at H to take the projection J on the free end of the tongue C, when
the latter is in the closed position as shewn in full lines.
To open out the eye A the tongue C is pushed downwards thereby compressing
the apring G, the slotted hole D allowing of this, the projection J is thus brought
cut of the recess H and the tongue can then be pivotted out, as shewn in dotted
lines and the block hooked on to an eyebolt or similar closed fitting and the tongue
returned to the closed position in which it is held by means of the pressure of the
spring G on the tongue C keeping the projection J in the recess H.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1st. In a Pulley block of the above mentioned type the combination of a
spring G and a hinged tongue C adapted to serve therewith as, and for the purpose
specified.
2nd. The improvements in pulley blocks consisting of the parts constructed,

page_text: arranged, and combined substantially as described with reference to the accom-
panying drawings, and operating as, and for the purpose specified.
Dated this first day of December 1897.
