therein and which is dimensioned to have a length less
than the length of the groove to enable endwise displace
ment of the bar between an outer or normal position
and an inner or operative position. The groove 58 and
the underlying groove 60 in the guide bar 56 are inter
connected by a slot 62 which extends through the bar
for ‘a distance in advance of the feed chute position to
thereof. The transfer plate 86 is formed with an elongate
slot 90 which extends angularly preferably at an angle of
about 45 degrees i 15 degrees through a part of the
plate underlying the actuator bar 20 during endwise dis
placement of the plate from normal to operative position.
A stud 92 depends from the actuator bar effecting en“

movement of the actuator bar 20 in response to forward
ably extending upwardly integrally from the actuator bar 10 and backward reciprocal movement of the transfer plate
20 to project through the slot 62 into the groove 58 to
86. It will be understood that the pin and slot may be
a level so that the abutment will engage the rearward
edge of the lowermost of the anchor plates 10 in the stack
30 to displace the lowermost of the anchor plates from
the stack into the inner portion of the groove during
actuation of the bar 20 from normal to operative position.
In normal position, the leading edge of the abutment
50 is adapted to be positioned rearwardly of the stack 30
of anchor plates 10 at rest on the guide bar 56 to enable
interchanged as between the actuator bar and the transfer
plate for transferring linear movement of one element in
one direction to linear movement of the other element in
a direction substantially perpendicularly thereto. The
slot 90 is dimensioned to have a length greater than the
hypotenuse of a right triangle having the length of dis
placement of the actuator bar 20 as one of its sides.
The transfer plate 86 is con?ned within its channel by
the abutment to clear the stack of eye-members whereby
the stack will rest on the guide bar with the lowermost

In operative postion, the
leading edge 51 of the abutment 50 is adapted to effect
displacement of the lowermost of the anchor plates for
a distance ‘corresponding to the length of the anchor plate
for corresponding movement of all of the anchor plates
in advance thereof lying in end-to-end relation in the
groove 58 to the anvil 14. Thus the abutment is adapted
to extend into the groove 58 for a distance which is no
greater than the height of a single anchor plate at rest
on the base of the groove and the abutment is dimen~
sioned to have a width which is less than the width of the
anchor plate and preferably about the width of the body
portion so that the slot 62 can be formed to a lesser
width than the groove 58 to leave side rails 64 upon
which the lateral edge portions of the anchor plates can
rest during passage through the groove. The ends of

but to militate against the overlapping of one anchor
plate with another in a manner such as would cause jam

In operation, with the elements in normal position, a
feed chute 12 ?lled with anchor plates 10 will be posi
tioned over the guide bar 56 so that the lateral edges or
?anges 24 of the lowermost anchor plate in the stack 30
will be at rest on the side rails 64 adjacent the slot 62
passing therebetween. The abutment 50 movable with
the actuator bar 20 will be positioned outwardly of the
stack of stay plates with the upper end of the abutment
at a level with the body portion of the lowermost of the
anchor plates in the stack.

operation of the cam on the common drive shaft and the
of the actuator bar 20 from normal toward operative
feed cam mounted thereon as described in the afore
mentioned application.
Referring now to FIG. 1, the feed slide 70 is operated
in reciprocal movement in response to the rotational
movement of the actuating cam on the drive shaft. Re
ciprocal movement of the feed slide 70 in the forward
direction is transmitted for reciprocal movement of the
actuator bar 20 in the crosswise direction through a trans
fer mechanism located in the bed of the machine to effect
movement of the actuator bar from normal to operative
positions and back responsive to movement of the feed
slide 70 from normal to operative positions and back
respectively.
The transfer mechanism comprises a lever arm 72
pivoted intermediate its ends on a pin 74 stationarily ?xed
position.
Displacement of the actuator bar 20 will carry the
abutment 50 through the slot 62 whereby the leading
50 edge of the abutment will come into engagement with
the rearward edge of the lowermost of the anchor plates
lying in the path thereof to cause displacement of the
anchor plate from the feed chute 12 into the channel 104
in advance thereof. The clearance between the bottom
wall at the leading end of the chute (106) and the base
of the groove 58 in the guide plate will enable displace
ment of only the lowermost of the anchor plates in re
sponse to movement of the abutment therethrough. The
remainder of the plates in the stack will be supported
on the abutment in spaced relation with the guide plate
while the abutment underlies the stack of anchor plates.
Forward displacement of the lowermost of the anchor
plates from the stack will be transmitted to other anchor
plates aligned in end-to-end relation in advance thereof
to the frame of the machine. One end of the lever arm
72 is provided with an elongate slot 76 dimensioned to
receive a pin 78 extending upwardly from the slide bar
pivotally to connect the lever arm 72 with the bar. The

the abutment 50 to cause outward displacement of the
abutment until it clears the stack of anchor plates in the
feed chute. Upon clearance, the stack will drop down
to bring the next anchor plate into position of rest on
the rails of the guide bar to assume the position of the
displaced anchor plate as the lowermost in the stack in
the path of the abutment in preparation for the next cycle
of operation.
It will be apparent from the foregoing that a simple
and ef?cient means is provided for the transmission of
movement from a forward movement as effected by the
feed cam to a crosswise movement for linear displacement
through the groove to the anvil, means mounting the
feed chute on one end portion of the guide bar with the
lowermost of the anchor plates in the stack resting in
the feed groove and with the leading bottom edge of
the chute being spaced from the base of the groove by
an amount greater than the height of one anchor plate
but less than two to enable only the lowermost of the
anchor plates to be displaced endwise from the feed chute
