Improvements in Machines for Setting Lacing Hooks.
I, WILLIAM HALKYARD, of No. 43 Elmwood Avenue, Providence, Rhode
Island, United States of America, Manufacturer, 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:-
My invention relates to machines for setting or fastening lacing hooks upon
leather or other material, and it consists in the employment of a feeding receptacle
for holding a disarranged mass of lacing hooks in proximity to the feed track upon
which they are to be deposited in regular order, and a supplementary hopper for
holding a primary disarranged mass of lacing hooks, and an intermediate feeding
device for maintaining a practically uniform quantity of lacing hooks in the feeding
receptacle, by the automatic transfer of lacing hooks from the disarranged mass in
the supplementary hopper to the correspondingly disarranged mass in the feeding
receptacle, as occasion requires. It also consists in the improved construction and
arrangement of other parts of the machine, as hereinafter set forth.

Figure 11
In the drawings, 10 represents the frame of the machine which may be supported
at the proper height from the floor of the room upon a suitable standard. The
hopper 11 is supported by means of a standard 12, and is provided with a
cover 13 and with a lower door 14, for the complete withdrawal of the lacing
hooks, from the hopper, when desired. The bottom of the hopper 11 is also
provided with the opening 15, within which is placed the vertically reciprocating
feeding bar 16, the upper end 17 of which, forms a carrier for carrying the lacing
hooks from the hopper 11, to the top of the partition 18, from whence they will
pass into the receiving chamber 20, in which is placed the reciprocating feeding
receptacle 19, the said chamber being provided with a hinged cover 21, held in its
closed condition by means of the spring 22, the said cover being provided at its
under side, with a lining of felt 23, or similar material, which serves to prevent
bruising the hooks when the machine is being run so rapidly as to throw them
against the cover. The reciprocating feeding receptacle 19, is open at the side 24,
adjacent to the slightly inclined guiding wall 25, and has an up and down
reciprocating movement along the said wall. To the guiding wall 25 is attached
by suitable means the inclined feed track 26, which is adapted to catch and retain
a number of lacing hooks from the feeding receptacle 19, while the mass of the
said hooks are making their downward movement along the side of the guiding
wall, the space between the track and the said guiding wall being made of
sufficient width, to loosely hold the heads of the hooks, so that only those hooks
which are properly presented will be caught and retained upon the track. The
wall of the receiving chamber 20, is provided with a recess 27, into the lower end
of which the feed track 26 enters, so that the upward movement of the feeding
receptacle 19, past the opening 28, through which the lacing hooks are made to
pass will not be obstructed. At the side of the plunger 29, is secured a flat plate 9
constituting the raceway track 30, which extends for nearly the whole length of the
plunger, and is recessed at 31, to provide for the passage of a lacing hook from the
feed track 26, to the edge of the raceway track 30, which forms one side of the race-
way 32, through which the lacing hooks are dropped by gravity one at a time to
engagement with the lips of the escapement lever 37. The upper extension 8 of
the plate 9 is arranged in line with the lower end of the feed track, and will form
a stop against which the lacing hooks on the feed track will rest at its downward
- position of the plunger. To the plunger 29 is attached a curved plate 35
provided with a stop spur 6, so arranged that as the plunger ascends, the said stop
spur will be caused to pass between the first and second lacing hooks on the feed
track, and thus allow only the first lacing hooks to pass into the recess 31, and to
thence drop through the raceway 32, to engagement with the upper lip 36, of the
escapement lever 37; the said escapement lever being pivoted to the side of the
plunger 29, by means of the pivot screw 38, and operated at the up and down
movement of the plunger by means of the fixed cam 39, attached to the frame 10 ;
the said escapement lever being also provided with the pin 40, adapted to enter
the recess 41 of the cam 39, by means of which the said lever is operated.. The

page_text: escapement lever 37 is also provided with a lower lip 42, which is offset from the
upper lip 36, so that upon the rocking movement of the said lever by engagement
with the cam 39, a single lacing hook will be fed from the lower end of the race-
way 32, to the holding rest 33 of the pivoted swinging head 34, for setting the
lacing hook in the leather, upon the downward movement of the plunger 29, and
the consequent turning of the swinging head 34, by means of suitable mechanism,
so as to bring the holding rest 33 over the anvil 70.
The construction of the swinging-head 34, is shown in Figures 8 to 14 inclusive,
in which the said swinging head is journalled by means of the spindle 71, to the
ears 72 at the lower end of the plunger 29. The sliding stop 73, which serves to
hold the lacing hook 75 upon the holding rest 33, when in line with the raceway
track 30, rests in the longitudinal groove or recess 74, made in the spindle 71, and
is caused to enter the path of the descending lacing-hook by means of the spiral
spring 76, one end of which rests against a shoulder on the said sliding-stop,
while its opposite end rests against the collar 77, which is made fast on the spindle,
and also serves to retain the sliding stop in the recess 74. The spindle 71 is also
provided with a collar 78 having in its periphery gear teeth which are in engage-
ment with similar teeth provided at the lower end of the lever 80, the said lever
being pivoted to the plunger, so that a rocking movement will be imparted thereto
by engagement with the stationary pin or roller 81, supported on the arm 89,
which is attached to the frame 10. In Figure 9, the roller 81 is represented in
dotted lines, and when the plunger is moved downward, the upper portion of the
lever 80 will come in contact with the said roller 81, whereby the lever will be.
rocked so as to cause the spindle 71 to turn.through one quarter of a revolution,
and thus carry the lacing hook from its horizontal position as first received upon
the holding-rest 33 as shown in Figure 13, to a vertical position as shown in
Figure 14, ready to be set in the leather or other material, and be also clinched
by coming in contact with the anvil, a fixed stop 82 being provided to positively
limit the said movement of the swinging-head. By referring to Figures
and 10,
it will be seen, that one ear of the plunger is cut away to form a cam 83, which
will be engaged by the sliding stop 73, when the said stop is rocked with the
spindle and will thus cause the withdrawal of the said stop away from the end of the
holding-rest 33, against the resilient action of the spring 76 as shown in Figure 12,
thus leaving the lacing hook free from the sliding stop, and as the sliding-stop is
being drawn away, the lacing hook will be firmly held by the sliding-holder 84,
held in the groove 85, the forward end of the said holder being hollowed out to
correspond with the shape of the post of the lacing hook. A spiral spring 86
rests with one end against the side of the collar 77, and with its opposite end.
against the head portion of the sliding-holder 84 thus tending to force the end of
the sliding-holder either into contact with the end of the holding-rest 33, or into
engagement with the post of the lacing-hook deposited upon the said rest in proper
position for setting. When the plunger 29 is being raised, the spindle 71 and.
Bwinging-head 34 will be rocked so as to carry the holding-rest 33 against the end
of the raceway track 30, and the sliding-holder will be caused to move away from.
the end of the holding rest 33 against the resilient action of the spring 86, by
means of a cam projection 87 shown in Figure 11, which is engaged by the.
shoulder 88, of the sliding-holder during the latter portion of its movement with.
the spindle 71, thus forming a passage for the descending lacing-hook and allowing
the same to come to a rest against the sliding-stop 73 as shown in Figure 1.
In order to preserve the lacing hook in its proper position upon the raceway
track, upon its downward passage from the recess 31, the forward edge of the
curved plate 35 which carries the stop spur 6 is made to project over the edge of
the raceway track and in close proximity thereto, as shown in the transverse
section Figure 7, thus effectively preventing the disarrangement of the lacing hook
in its passage from the recess 31, to the raceway 32, such disarrangement being
prevented by the resulting engagement of the plate 35 with the outwardly
projecting tubular portion of the lacing hook.

page_text: The feeding receptacle 19, is provided with a guide rod 43 which passes through
the guide bearing 44, and the downward movement of the feeding receptacle is
checked by the spiral spring 45, upon the guide rod, and the said feeding receptacle
is operated in its up and down movement, by means of the pin 46, at the side of the
cam 47, on the shaft 48, the said pin being arranged to enter the curved slot 49, in
the lever 50, which is pivoted at the screw 51, and is connected at its outer end
with the side of the feeding receptacle, by means of the connecting rod 52. Upon
one end of the shaft 48, is placed the gear 53, which engages with the pinion 54, on
the driving shaft 55, and to the outer end of the driving shaft, is secured the
clutch pulley 56, which is normally loose upon the shaft, but is connected with the
shaft at the will of the operator, by means of the spring actuated sliding key 57,
which is caused to move backward to release the pulley by means of the engagement
of the end 58, of the arm 59, therewith, the said arm being secured to the rock-
shaft 60, to which is also secured the bent lever 61, provided at its side with the
roller 62, which engages with the periphery of the cam 47, the said lever being
held in its raised position, by means of the spiral spring 63; and to the outer end
of the lever 61, is attached the rod 64, which connects with a pedal, the engaging
movement of which is controlled by the operator of the machine. The plunger 29
is operated in its up and down movement by means of the lever 65, which is pivoted
at the screw 66, and is connected for operation with the crank pin 46 on the side of
the cam 47 by means of the connecting rod 69; and the feeding bar 16, is attached
to the downwardly extending arm 68, of the feeding receptacle 19, so as to be
reciprocated therewith.
The operation of the machine will be as follows: The feeding receptacle 19, and
the hopper 11, being first filled with lacing hooks, the operator presses down the
pedal with his boot, thus drawing down the bent lever 61 to rock the shaft 60, and
throw the end 58 of the arm 59 out of engagement with the spring actuated key 57,
which then springs into engagement with the clutch pulley 56, to cause the
rotation of the driving shaft 55, and such rotation will continue as long as the foot
of the operator rests upon the pedal; but upon the release of the pedal, the action
of the spring 63, will cause the roller 62, to enter the recess 67, of the cam 47-
thus causing the engagement of the end 58, of the arm 59, with the sliding key 57,
to withdraw the same from engagement with the pulley 56, thus stopping the
machine. Upon setting the machine in motion, the lacing hooks in the feeding
receptacle 19, will be placed upward over the inclined feed-track 26, and upon the
downward movement of the same, some of the said hooks will be deposited in a
proper position upon the said feed track, and will slide to the lower end of the
same.
In the meantime, the feeding bar 16, will have raised a number of lacing hooks
upon its upper end 17, to the top of the partition 18, from whence they will slide
into the simultaneously elevated feeding receptacle 19, so as to keep the said
receptacle properly filled with lacing hooks, the hooks raised by the feeding bar 16,
not being able to pass over the partition 18, into the feeding receptacle, when the
said feeding receptacle is completely filled with hooks, thus the feeding receptacle
will be automatically kept even full, under all circumstances, whereby a sufficient
number of hooks will be caused to pass over the inclined track so that a constant
supply of looks will be provided for the setting plunger; and upon each up and
down movement of the setting plunger, a single lacing hook will be fed from the
feed track to the raceway track, by the conjoint action of the stop spur 35, and the.
upward extension 8 of the plate 9. The first lacing hook which is fed from
the feed track to the raceway track, will pass by gravity to contact with the upper
lip 36, of the escapement lever 37, which hook, upon the downward movement of
the plunger, and the resulting backward movement of the escapement lever, will
drop from the upper lip 36, to the lower lip 42, and thereafter, upon every up and.
down movement of the setting plunger, a single lacing hook will be fed to the
holding rest :33, of the swinging head 34, which is pivoted to the lower end of
the plunger 29, and upon the downward movement of the plunger 29, and the

page_text: resulting swinging movement of the head 34, the lacing hook will be pressed
against the anvil 70.
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. In a machine for setting lacing hooks, the combination with the hopper, and
the receiving chamber, of a device for feeding the lacing hooks from the hopper,
loosely, into the receiving chamber, the feed track, and the feeding receptacle
located in the receiving chamber, and adapted to deposit the lacing hooks upon the
feed-track substantially as described.
2. In a machine for setting lacing hooks, the combination with the inclined feed
track, the reciprocating plunger provided with the raceway track, and means for
feeding the lacing hooks, one at a time, from the feed track to the raceway track,
of the escapement lever, pivoted to the side of the plunger, and provided with the
offset holding lips one below the other, and the fixed cam for operating the said
escapement lever, upon the upward movement of the plunger, substantially as
described.
3. In a machine for setting lacing hooks, the combination with the setting
plunger and its attachments, the operating lever, connecting rod, and crank pin, of
the inclined feed track, the reciprocating feeding receptacle adapted to deposit the
lacing hooks upon the feed track, the connecting rod, and the operating lever
provided with a curved slot, adapted to receive the crank pin which operates the
setting plunger, substantially as described.
4. In a machine for setting lacing hooks, the combination with the inclined feed
track and the setting plunger provided with a raceway track having a recess
adapted to receive the lacing hook from the end of the feed track of the guide
plate arranged at the lower side of the recess and having its forward edge
projecting reversely of the raceway track and at a slight distance outwardly
therefrom so as to bear againt the tubular portion of the lacing hook and guide
the lacing hook from the recess into the raceway of the plunger, substantially as
described.
