PROVISIONAL SPECIFICATION.
An Improvement in Mast Hoops.
We, CHARLES SMITH MOTT of Patchogue, Long Island, in the County of
Suffolk, and State of New York, United States of America, Oyster Planter, and
GEORGE HENRY SHAFFER, of 34 South Oxford Street Brooklyn, in the County
of Kings, and State of New York, United States of America, Oyster Merchant,
do hereby declare the nature of this invention to be as follows:-
:―
Our invention has for its object to provide a sectional hoop capable of being
readily sprung around a mast, its ends securely fastened when said hoop is in
position.
The hoop is constructed preferably of tough wood, such as ash, oak, or hickory,
and is made with two abutting ends, the one being formed with a central dovetail
tongue, the end face of which is bevelled inward, while the other has a dovetail
recess, practically corresponding in length and breadth to the equivalent measure-
ments of the tongue which it is adapted to receive, the end wall of the recess being
inwardly and downwardly bevelled to receive the bevelled face of the tongue.
semi-circular sleeve is adapted to slide upon the hoop and the said sleeve is usually
provided at one or both ends with an aperture.
A
When the hoop is to be applied to a mast, the sleeve is slipped from over the
united ends of the hoop and the tongue detached from the recess. The ends of
the hoop are then bent or carried in opposite directions a sufficient distance to
enable the hoop to be readily sprung upon the mast, and the tongue is passed into
the recess and the sleeve slid over the joint and securely held in such position by a
screw or equivalent device. The hoop is, in like manner, expeditiously and
conveniently disengaged from the mast.
The connections at the ends of the hoop are exceedingly simple, and when such
connections are made the sleeve will remain permanently in position or until
purposely disturbed.

COMPLETE SPECIFICATION.
An Improvement in Mast Hoops.
We CHARLES SMITH MOTT of Patchogue, Long Island, in the County of
Suffolk and State of New York, United States of America, Oyster Planter, and
GEORGE HENRY SHAFFER of 34 South Oxford Street, Brooklyn, in the County
of Kings and State of New York, United States of America, Oyster Merchant,
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 :-
Our invention relates to an improvement in mast hoops, and has for its object
to enable the hoop to be readily sprung into position around a mast, and to provide
means whereby the ends of the hoop may be securely fastened when said hoop is
in position upon the mast.
The invention consists in the novel construction and combination of the several
parts, as hereinafter set forth and claimed.

page_text: Reference is to be had to the accompanying drawings, forming part of this
Specification, in which
Figure 1 is a face view of the hoop having its ends united.
Figure 2 is an edge view of the hoop illustrating the means of connecting the
ends.
Figures 3 and 4 are perspective views of the ends of the hoop.
Figure 5 is a perspective view of the locking sleeve.
Similar figures of reference indicate corresponding parts in all the views.
The hoop 10 is constructed preferably of a tough wood such as ash, oak, or
hickory, and the hoop is made with two abutting and interlocking ends 11 and 12.
The end is formed with a central tongue 13 of essentially dove-tail shape, the
under face of which tongue is bevelled inward as shewn at 14. In the end 12 a
dove-tailed mortise 15 is formed corresponding in length and breadth to the tongue
which it is adapted to receive. The end wall of the mortise 15 is inwardly and
downwardly bevelled to fit the bevelled face of the tongue and a sleeve 16 of a
cross-sectional form and longitudinal curvature corresponding to the sectional form
and curvature of the hoop is adapted to slide upon the hoop, the said sleeve being
usually provided at both ends with a hole 17.
When the hoop is to be applied to à mast, the sleeve 16 is slipped from over the
united ends of the hoop and the tongue 13 is disengaged from the mortise 15.
The ends of the hoop are then bent or sprung in opposite directions a sufficient
distance to enable the hoop to be sprung upon the mast, after which the tongue is
again engaged in the mortise 15 and the sleeve is slid over the joint and secured in
such position by a screw or equivalent fastening inserted through the hole or
holes 17. It is obvious that the hoop may in like manner be expeditiously disen-
gaged from the mast. The connections at the end of the hoop are exceedingly
simple and when such connections are made, the sleeve will remain permanently in
such position or until purposely disturbed. It will be understood that the shape
of the tongue may be varied without departing from the spirit of the invention,
and that whatever the shape of the tongue may be, the receiving mortise is
correspondingly shaped.
Having now particularly described and ascertained the nature of the said inven
tion and in what manner the same is to be performed, we declare that what we
claim is,
1. As an improved article of manufacture a mast hoop constructed with two
abutting and interlocking ends and provided with a sleeve adapted to slide over
said ends, as and for the purpose specified.
2. As an improved article of manufacture a mast hoop constructed with two
abutting and interlocking ends, one of which is provided with a dovetail tongue
and the other with a dovetail mortise adapted to receive the tongue, and a sliding
sleeve adapted to cover the connected ends of the hoop, as and for the purpose
specified.
3. The combination, with a mast hoop constructed with two abutting and inter-
locking ends, one of which is provided with a dovetail tongue having a bevelled
outer end face, the other end being provided with a mortise adapted to receive the
tongue, of a sleeve fitted to slide upon the hoop and means, substantially as
described, for locking the sleeve over the joint of the hoop, as and for the purpose
specified.
