page_text: hereinafter described.
In carrying out my invention I provide side-framing carrying one, two or more
sheaves at its upper or lower end and a hook at the other end of framing my inven-
tion relates to the hook and I improve it and its cross-bar bearing in the following
manner.
My cross-bar to carry the hook is made in one piece with a central hook-hole, in
contra-distinction to the old style crane-hook cross-bar made in two parts divided
across the hook-hole.
I next provide a lower racing-ring formed from a ring of hardened steel and also
an upper racing-ring formed from hardened steel, the lower racing-ring would
rest on the upper face of the cross-bar.
I next provide my improved hook so formed at its carrying end that it can bo
readily threaded through the central hook-hole formed in solid cross-bar, the upper
end of the hook is formed with a ueck-part which may be parallel or which may
be slightly larger at the upper part than at the lower part of such neck; above the
neck I form the bearing-collar in conjunction with the neck as part thereof; the
hook, the neck, and the bearing-collar forming one solid single piece.
The upper racing-ring is threaded over the point of hook and pushed up under
the solid hook-collar.
The hook is threaded through the central hole in solid cross-bar, the point passing
first and the remainder of the hook following, the continuation of hook just below
the neck being of such configuration and section as to permit of the hook-neck
being moved vertically and centrally over the hole in solid cross-bar, and thus enable
the neck of hook to be lowered into the beforementioned central hole on cross-bar;
suitable balls or rollers would be placed between the steel racing-rings.
The cross-bar carrying its hook would next be connected to the side framing
below or above the sheaves, and a loose collar then threaded over the point of hook
and moved up to bottom of hook neck under the solid cross-bar and secured to the
hook by means of a set pin or equivalent fastenment.
In using my improved crane-hook, the sling carrying the weight to be lifted
would pass over the point of hook in the usual manner and be supported by the
hook, and my improved hook could then be swivelled round easily for convenienco
of loading, the balls or rollers revolving between the ring the solid collar or head

page_text: of the improved-hook being safer than the old style collar with end of old-style hook
riveted over such loose collar.

I, ISAIAH PLATT, of King's-Hill, Wednesbury, in the County of Stafford,
Mechanical Engineer, 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:-
This invention consists of the arrangement of parts hereunder described consti-
tuting a complete and effectual rotating crane-hook.
I will now proceed to describe with reference to the accompanying drawings 'the
manner in which my invention is constructed and used.
Figure 1 represents a side elevation of the improved crane-hook ready for use.
Figure 2 represents a broken-off view of the upper portion of my improved hook.
Figure 3 represents a sectional elevation of improved crane-hook ready for use.
igure 4 represents a plan of the solid cross-bar.
In carrying out my invention I provide the side-cheeks a carrying one, two or
more sheaves b as marked in dotted lines; the side-cheeks or framing a and the
sheaves do not claim to be new, as my invention relates to the hook and its
cross-bar which I improve in the manner next described.
My improved cross-bar c as shewn in detail at Figure 4 is made in one piece
through which is pierced a central-hole d.
1 next provide a lower racing-ring c formed from a ring of hardened steel and I
also provide an upper racing-ring f likewise formed from hardened steel; the lower.
racing-ring rests on the upper face of the cross-bar and is secured thereto by
means of screw's studs or other equivalent fastenments.
I next provide my improved hook g of suitable dimensions at its carrying end to
permit of the hook point g¹ being readily threaded through the central hole d
formed in solid cross-bar the upper end of the hook g is formed with a neck
part above the neck I form the bearing-collar in conjunction with the
neck and as part thereof, the hook g, the neck and the bearing-collar form-
ing one single forging,
The upper racing-ring is threaded over the point gl of hook g and pushed up
under the solid collar and secured thereto by means of screw-pins, studs, or other
equivalent fastenments.
The hook carrying its upper racing-ring f is threaded through the central-hole d
in solid cross-bar c, the point gl passing and the remainder of the hook following,
the continuation of the hook g below the neck g2 being of such configuration and
section as to permit of the hook neck being moved vertically and centrally over
the hole in solid cross-bar to enable the neck g to be lowered into the before-
mentioned central hole of cross-bar e; suitable balls would be placed between
the steel racing-rings e and f and when the hook was so connected it would be in
its proper position to revolve within the cross-bar c; a loose collar would then be
threaded over the point gl of hook and moved up to under side of the solid cross-
bar cand secured to the hook 9 by means of a set-pin k or other equivalent fasten-
ment. The cross-bar c carrying its hook would be connected to the cheeks or

page_text: side-framing a either below or above the sheaves in accordance with the manner in
which it was intended to use the improved hook and its solid cross-bar.
In using my improved crane-hook the sling carrying the weight to be lifted
would pass over the point e¹ of hook in the usual manner and be supported by
the hook g, and my improved hook could then be swivelled round easily for con-
venience of loading, balls h revolving between the hardened steel rings c and f.
My improved hooky and solid cross-bar constitute substantial improvements
in crane-hooks.
Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is constructed and used, I declare that
what I claim is :-
1st. A solid crane-hook consisting of a lower hook-part the upper portion or neck
of which is formed with a suspending-collar the neck of such hook taking into the
central passage of a solid cross-bar and revolving thereon, as illustrated and
described in relation to Figures 1 and 3.
2nd. In a crane-hook the utilization of a hook the neck and collar of which are
formed as part of the hook, as illustrated and described in relation to g² and g³
Figure 2.
3rd. In a crane-hook the utilization of a solid cross-bar, as illustrated and
described in relation to Figures 1, 3 and 4.
