Improvements in Machines for Setting Lacing Hooks.
We, MARSHALL HENRY PEARSON, of 16 Blue Boar Lane Leicester, Engineer,
and CHARLES BENNION, also of 16 Blue Boar Lane, Leicester, Engineer, do
hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in that type of machines for clenching
lacing hooks, studs &c. which employs a stationary inclined shoot down which the
hooks &c. pass to a reciprocating shoot formed in the clenching plunger or spindle,
and consists of an improved mechanism for conducting the hooks from the stationary
shoot, through the reciprocating shoot, to the clenching die.
In hook setting machines of the above type it is necessary to provide a space at
or near the junction of the stationary and reciprocating shoots to allow the hooks
to turn through a considerable angle and thus accoinodate themselves to the
reciprocating shoot. Hitherto this space has been bounded on one side by the end
of the stationary shoot and on the other side by one wall of the reciprocating
shoot, which have been so formed that the space between them increased as the
clenching plunger descended, allowing many of the hocks to fall from the machine,
but, according to our invention the space is provided between parts which
reciprocate with the clenching plunger and which remain at a fixed distance from
each other thus preventing the aforesaid loss of hooks.
Our invention also consists of improved means whereby the hooks are placed
in the correct position under the clenching plunger for entering the hole in the
leather or other material required to receive the hooks, and also for engaging with
the lower clenching die.
In machines of the type referred to, the hooks in falling down the reciprocating
shoot have to pass round a sharp curve which frequently arrests their passage.
To remedy this we arrange a moving finger which pushes each hook from the
point at which it stops to the required position, where it is retained by a yielding
stop formed to suit the shape of the hook. This stop assists in placing the
hook and prevents its being moved in any direction by the vibration of the
machine &c.
In conjunction with the movable finger it may be necessary to use some form of
pawl, detent, escapement or other device, which will prevent each hook from
falling immediately to the bottom of the reciprocating shoot but will arrest its fall
and release it when required.
A further part of our invention consists of a wedge attached to the clenching
plunger and formed to fulfil the twofold function of preventing more hooks than
one at a time entering the reciprocating shoot, and of regulating the position of
the hooks in the stationary shoot so that they cannot be trapped between the
moving and stationary parts of the hook arranging mechanism.

We MARSHALL HENRY PEARSON of 16 Blue Boar Lane, Leicester, Engineer,
and CHARLES BENNION also of 16 Blue Boar Lane, Leicester, 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 :-
Our invention relates to improvements in that type of machines for clenching
lacing hooks, studs &c. which employs a stationary inclined shoot down which the
hooks &c. pass to a reciprocating shoot formed in the clenching plunger or spindle,
and consists of improved means for conducting the hooks from the stationary
inclined shoot, through the reciprocating shoot to the clenching die; for placing
the hooks in the correct position under the clenching die, and for regulating the
position of the hooks in the stationary inclined shoot.
In the following description of our invention reference is made to the
accompanying drawings in which :-
Fig. 1. is a side elevation of the plunger and inclined shoot, shewing the plunger
in its highest position.
Fig. 2. is a side elevation of the plunger and inclined shoot shewing the plunger
in a lower position.
Fig. 3. is a part front elevation of the machine shewing the plunger and device
for moving the hooks into the correct position under the die.
Fig. 4. is a part front elevation of the machine with the moving parts shewn in
different positions from those shewn in Fig. 3.
Fig. 5. is a side elevation of lever E' aud finger E.
Fig. 6. is a section through X. X. Fig. 1.
Fig. 7. is a section through Y. Y. Fig. 2.
Fig. 8. is a front elevation of the die with the front plate C removed.
Fig. 9. is a front elevation of the die complete.
Fig. 10. is a plan of the die.
Figs. 8 to 10 are drawn to a larger scale than Figs. 1 to 7.
A is a reciprocating plunger in which is formed a groove or shoot A¹ to receive
hooks &c. from the stationary inclined shoot B and to conduct them to the
elenching die C, formed in or carried by the lower end of the plunger A.
In connection with the shoot A¹ it is necessary to provide a space A to allow
the hooks to turn through a considerable angle and thus accomodate themselves to
the lower part of the shoot A. According to our invention this space is provided
between arts which reciprocate with the clenching plugger and which remain
at a fixed distance from cach other, thus preventing the hooks falling from the
machine as sometimes occurs in machines of this type as made prior to our
invention.
D. Fig. 1. shews a hook which has just left the stationary shoot and has partly
turne itself prior to passing down the reciprocating shoot. The turning space A
is bounded by walls A A formed in or attached to the plunger A.
Fig. 1. shews the plunger A in its highest position where it receives the hooks
one at a time from the inclined shoot, while Fig. 2. shews the plunger in a lower
position, the hooks in the inclined shoot having moved downwards ready for the
lowest one to fall into the reciprocating shoot when it next rises.
In machines, of the type referred to, the hooks in falling down the reciprocating
shoot have to pass round a sharp curve such as C₁ which frequently arrests their
passage.
E, Figs. 3, 4, & 5, is an adjustable movable finger attached to the lever E¹ which

page_text: is pivotted at E to the framing of the machine, and is provided at E³ with a cam-
shaped extremity which engages with the roller A carried by the plunger A. In
this manner the finger E is made to push the hooks into their correct position
under the clenching die as shewn at D¹ Fig. 3, the spring E being provided to
move the finger E out of the way of the die Ċ as the latter descends.
We find by practice that in order that the speed of the machine may not be
limited owing to the time occupied by the hooks in falling from the inclined shoot
to the clenching die, it is advantageous to intercept the falling hooks as near to
the die as convenient and to liberate them in time to reach their correct position
before the next descent of the plunger.
To effect this we might employ any suitable form of pawl, detent, escapement,
or other device, but prefer to arrest the downward progress of the hooks by means
of finger E which is made to obstruct the falling hooks as shewn at D Fig. 3, and
to release them as shewn at D³ Fig. 4.
When a hook is pushed into position by the finger E, it is held by the yielding
stop C, which is pivotted at C³ and pressed down by the spring C¹ with just
sufficient pressure to keep the hook from being moved by the vibration of the
machine, but which will readily yield to allow the hook to be placed in position,
or to be removed from the machine after being clenched in the leather &c.
recess C under the stop C2 is formed to suit the shape of hook for which the
machine is to be used.
The
Figs. 8, 9, & 10. shew the construction of the die C & stop C sufficiently well to
render further description unnecessary.
In Figs. 1 & 2. a wedge shaped piece is shewn at Fattached to the plunger A.
As the plunger rises, the wedge passes between the lowest hook in the inclined
shoot and those above it thus preventing more than one hook at a time from
entering the reciprocating shoot, and if when the inclined shoot is full of hooks, one
or more hooks at the upper end of the inclined shoot are in danger of being trapped
between the moving and stationary parts of the hook arranging mechanism which
is not shewn in the drawings, the wedge F. according to our invention will raise
the whole row of hooks (except the lowest one) and thus move the upper ones out
of danger of being trapped. These two results have been previously obtained by
separate means, but so far as we are aware, no wedge like that shewn at F has ever
been employed to perform both functions. The wedge F may be made adjustable
as regards its width, but we prefer to make it as shewn and of suitable width for
both purposes.
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 a machine for setting lacing hooks &c. a plunger in or on which is formed
a shoot provided with a space in which the hooks may turn, so as to accomodate
themselves to the lower part of the shoot, such space being bounded by walls
which reciprocate with the plunger.
2. In a machine for setting lacing hooks &c. a movable finger as shewn, or
similar device actuated by any suitable part of the machine, to move the hooks
into the correct position under the clenching die.
3. In a machine for setting lacing hooks &c. a clenching die provided with a
yielding stop to prevent the hooks after being placed in position, from being moved
in either direction by the vibration of the machine, substantially as and for the
purposes described.
4. In a machine for setting lacing hooks &c. a wedge or similar device to
prevent more than one hook at a time from entering the reciprocating shoot, and
also to so regulate the position of the hooks in the stationary shoot that none of
them shall be trapped between the stationary and moving parts of the hook sorting
mechanism.

page_text: 5. In a machine for setting lacing hooks &c. means for intercepting the hooks
when falling down the reciprocating shoot and for liberating them when required
substantially as and for the purposes described.
