PROVISIONAL SPECIFICATION.
An Improvement connected with "Parallels" used in Gymnasiums.
I, FRED LEAT of 1 Merrett. Road, Brockley, Kent, Gymnasium Appliances
Manufacturer, do hereby declare the nature of this invention to be as follows:-
11
According to the ordinary method of constructing the bottom cross rails or base
of parallels used in Gymnasiums, stout strips of wood are employed to which the
uprights or posts are secured by angle brackets and by bolts passing up from the
underside of the cross rails into the uprights, the whole with the hand rails or parallel
bars being in one structure and only capable of being carried through very wide
doorways, or gate openings.
Now the object of my invention,-is to make the article in two distinct structures,
so that they can be carried through narrow doorways, ordinary passages, and the like,
and for this purpose I make the intermediate portions of the cross base rails of metal
moulded in two pieces, one having sockets with parallel sides but at an angle, or
lozenge shape let into short ends of cross rails. The other casting is of box shape
with lozenge shaped studs projecting from a partition in a box like article, into one
side of which the other short end of cross rail is inserted, the studs taking into the
sockets of the other casting.
The box like article has an ear for the passage of a bolt which also passes through
the ends of the longitudinal basé rails to bind the bottom part of the structure firmly
together.
I use the ordinary vertical screw bolts for connecting the cross rails to the uprights
but instead of having washers under the heads of the bolts, I employ plates with tail
pieces, one of which is in piece with the box before mentioned and the other projects
to engage in a socket forming part of the end of the former tail piece, a screw fixing
the two parts together.

COMPLETE SPECIFICATION.
An Improvement connected with "Parallels" used in Gymnasiums.
I FRED LEAT, of 1, Merrett Road, Brockley, Kent, Gymnasium Appliances
Manufacturer, do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
According to the ordinary method of constructing the bottom cross rails or base
of parallels used in Gymnasiums, stout strips of wood are employed to which the
uprights or posts are secured by angle brackets and by bolts passing up from the
underside of the cross rails into the uprights; the whole with the hand rails or parallel
bars being in one structure and only capable of being carried through very wide
doorways or gate openings. Now the object of my invention is to make the article
in two distinct structures, as represented at Figure 1 of the annexed drawings, so
that they can be carried through narrow doorways, ordinary passages and the like;
and for this purpose I make the intermediate portions A of the cross base rails B on
one side, of metal, moulded with sockets from the base of which diamond shaped
studs C. C. project, see detached view Figure 2. Each socket has parallel sides for
the reception of correspondingly shaped ends of the other short base rails D. D.

page_text: The studs C. C. take into the ends of the other short cross rails D, the faces of
which are covered with metal caps, see Figures 3 and 4, and have holes and
sockets E E for the studs C. C. to pass into.
The socket A has an ear F for the passage of a bolt G which also passes through
the ends H. H. of the longitudinal base rails I. 1. to bind the bottom part of the
structure firmly together.
I use the ordinary vertical screw bolts for connecting the cross rails D. D. to the
uprights J. J. but instead of having washers under the heads of the bolts I employ
plates as at K. Figure 5, a portion of which project to engage in a recess L of
the socket, the screws G. G. fixing the two parts together to constitute the Gymna-
sium "parallel."
When a footboard is placed over of the inner cross-rails B. D. I provide the
board with lips to engage in the openings M. M. of the longitudinal side rails I I.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of Gymnasium Parallels in two parts, as shown at Figure 1
of the annexed drawings as and for the purposes described.
2. Fitting short inner ends of cross rails of Gymnasium Parallels with stud
and socket ends for attachment of one to the other and the locking of same by cross
bolts G. G. as set forth and as shown on the annexed drawings.
