Improvements in Locking Devices for Boot and Shoe Nailing
Machines.
We, RICHARD WILKINSON BATEMAN, Shoe Maker, and Lorrus HANSON BATEMAN,
Mechanic, both of 5, Hanover Street, Halifax, in the County of York, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improvements in locking devices for locking the spindle
of the horn in nailing machines for nailing boots and shoes, the object being to so
construct the locking device that the parts will automatically adjust themselves
and prevent friction and consequent wear and tear; the spindle is also more easily
locked and unlocked.
According to this invention we employ inside the bracket or bearing of the spindle
a short stud carrying a boss in which is a semi-circular recess in which is a steel
runner or bowl, and resting against the bowl or runner and loosely carried thereby is
a rocking block with a recess in it which rests on the said bowl or runner. Against
the loose rocking block the ordinary wedge operated by the toggle rests. The
wedge is operated by any of the well known methods, and to lock the horn is
forced between the rocking block and a loose strip resting against the spindle to be
locked.
By making the block loose and free to rock on the bowl it automatically adjusts
itself to the locking wedge and is thereby efficient in its action, less liable to wear
and tear, and requires less fitting.

We, RICHARD WILKINSON BATEMAN, Shoe Maker, and LorruUS HANSON BATEMAN,

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:-

and unlocked.
Such being the nature and object of our said invention, the following is a complete
description of same, reference being had to the accompanying drawing which is a
side elevation, partly in section, of part of the spindle of the horn with our improved
locking device applied thereto.
According to this invention we employ inside the bracket or bearing 1 of the
spindle 2 a short stud 3 carrying a boss 4 in which is a semi-circular recess 5 in which
is a steel runner or bowl 6, and resting against the bowl or runner 6 and loosely
carried thereby is a rocking block 7 with a recess 8 in it which rests on the said bowl
or runner 6. Against the loose rocking block 7 the ordinary wedge 9 operated by
the toggle 10 rests. The toggle 10 is operated by any of the well known methods
such as treadle and lever 12, and to lock the horn the wedge 9 is forced between
the rocking block 7 and a loose strip 11 resting and fitting against the spindle 2 to
be locked.
By making the block 7 loose and free to rock on the bowl 6 it automatically adjusts
itself to the locking wedge 9 and is thereby efficient in its action, less liable to wear
and tear, and requires less fitting.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
(1) In devices for locking the horn in boot and shoe nailing machines the use of a
wedge 9 combined with a rocking block 7 carried on an anti-friction bowl or runner 6
working in a semi-circular recess 5 in a boss 4 secured to the machine by stud 3, as
herein described and substantially as illustrated by the accompanying drawings.
(2) The bowl or runner 6, rocking block 7, wedge 9, and loose strip 11, all in
combination operated and operating in the manner herein described and substantially
as illustrated by the annexed drawings.
