Improvements in Wings of Tower and other Bolts.

page_text: Improvements in Wings of Tower and other Bolts.
I, FREDERICK GARLAND of Castle Hill Saw Mills, near South Molton, in the
County of Devon, Builder, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in tower bolts, spring bolts and the like.
In tower and other bolts with square wings when used in a vertical position the
shaking of the doors to which the bolts are attached causes the shank or shoot of
the bolt to move off the edges of the wings and drop down. To avoid this and
also to allow the shank or shoot of the bolt a quicker means of going home to its
intended place I make the wings of the bolts with bevels hollows or slots inside to
receive the shank or shoot of the bolt. This at once throws the shank or shoot
back against the plate and makes it secure. Ordinary bolts also when fixed at
the bottom of doors are liable with the shaking of the doors to fall down and my
improvement when applied to both wings top and bottom enables it to be used for
either right or left hand.
My improvement can also be applied to the wings of bolts with square or round
shoots and with fixed or swiveled shanks and when so applied dispenses with
springs. It can be also applied to monkey tail bolts either with square or round
shoots and with or without a swivel shank and in the case of these bolts the tail
can be kept close to the door instead of projecting out as heretofore.

Improvements in Wings of Tower and other Bolts.
I FREDERICK GARLAND, of Castle Hill Saw Mille, near South Molton, in the
County of Devon, Builder, 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 relates to improvements in tower bolts, spring bolts, barrel
bolts and the like. In tower and other bolts with square wings, when used in a
vertical position, the shaking of the doors to which the bolts are attached sometimes
causes the shank or shoot of the bolt to move off the edge of the wing, and drop
down. To avoid this and also to allow the shank or shoot of the bolt a quicker
means of going home to its intended place, I make the wings of the bolts with
bevels, hollows, recesses or the like to receive the shank or shoot of the bolt.
This throws the shank or shoot back against the plate and makes it secure.
Ordinary bolts also, when fixed at the bottoms of doors, are liable, from the
shaking of the doors, to fall down; and my improvements, when applied to both
wings, enables it to be used for either right or left hand.

page_text: My invention is applicable to the wings of bolts with either square or round
shoots, and with fixed or swivelled shanks, and when so applied, springs are
rendered unnecessary. It may also be applied to monkey-tail bolts, either with
squaro or round shoots, and with or without a swivel shank; and, in the case of
these bolts, the tail can be kept close to the door, instead of projecting outwards
as heretofore.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is a front view of a bolt fitted in accordance with my invention.
Fig. 2 is a side view of the same, and
Figs. 3, 4 and 5 are detail views showing various forms of recesses in the
wings.
a is the plate, the bolt, the shank or shoot, and d d the wings. Eight
examples of recesses are shown at e, f, g, h, k, l, m and n, either of which forms
may be used. Both wings are similarly recessed so as to be applicable to right or
left hand use.
Having now particularly described and ascertained the nature of my said inven-
tion, and in wint manner the same is to be performed, I declare that what I
claim is :-
1. The improvements in wings of tower and other bolts, substantially as and for
the purposes described.
2. In tower bolts, spring bolts, barrel bolts and the like, the application and use
of recesses formed in the wings, substantially as and for the purposes herein before
described and illustrated by the drawings.
