Application October 29, 1935, Serial No. 47,283
13 Claims.
This invention relates to apparatus, commonly
known as distributors, by which such fastenings
as nails may be taken from a mass and delivered
in loads, each including a definite number of
5 fastenings all arranged with their points in the
same direction. This may be for the ,successive
delivery of the loads of fastenings to a heel
attaching machine.

In apparatus of the character above indicated,
10 a well-known arrangement is that disclosed in
Letters Pat-ent of the United States No. 1,005,303,
Pope, October l0, 1911. The fastenings are re
ceived by the apparatus of that patent from a
rotary drum upon a grooved raceway, without
l5 any deñnite direction of the heads and points,
and are acted upon during their passage between

ing member below the upper raceway-section may
be established, while by the horizontal adjust
ments the alinement of the grooves in the re
versing :member and in the raceway may be
fixed accurately> and also -the normal space be
tween the extremities vof said reversing member
and the raceway determined. I prefer to obtain
these variations in positionV by a mounting for
the reversing membenwhich mounting comprises 1,0
two supporting members respectively movable

clamped in place by screws passing through open
ings which give a capacity for relative lateral
movement between said screws and the elements 1.5

member termed a balancing-bar. This device
permits the nails moving heads ñrst along the

grooves corresponding to those of the raceway the

15 at each end a rack 22, with which racks mesh
pinions 24 upon a shaft 26 rotatable by a hand
wheel 28. By turning the hand-wheel the op
erator may lessen the space to be bridged by
short nails and lengthen it for long nails.
Such a single adjusting device for the balanc
20
ing-bar as that just outlined furnishes means
only for a change of nail-size, and leaves the
correction of manufacturing defects and mainte
nance-difficulties unprovided for and frequently
25 requiring considerable labor. The present in
vention furnishes means for readily obtaining the
proper relation of the elements. At each side
of the frame I0, in the same general location in
which the balancing-bar has been arranged to
30 slide longitudinally of the raceway in previous
organizations, I arrange for like movement in
approximately horizontal direction a bracket 30.
This bracket may be in the form of an angle
piece having a horizontal arm 32 extending
35 transversely of the raceway, and from the outer
adjusting means arranged to independently vary
the relation of the reversing member to the race
way in directions substantially at right-angles to 15
each other.

reversing member arranged for contact with fas

other member being variable in position upon
the first supporting member approximately ver 25

the two supporting members 30 and 34, with their
55 respective adjusting means 3B, 38 and 40, 42, fur
nish a universal mounting for the balancing-bar
and its adjusting gearing. If, either in the as
sembling or the use of the apparatus, it is found
that there is not a proper vertical relation be
60 tween the grooves in the balancing-bar and the
grooves in the race-way bars l2, it may quickly be
righted and the desired normal position attained
by loosening the screws 42, raising or lowering the
block 44 with the balancing bar and its adjusting
65 shaft 26 and then resetting the screws. Or, if the
raceway-grooves and balancing-bar-grooves are
out of alinement transversely, an adjustment of
the bracket 3D and the balancing bar upon the
frame under the control of the screws 33 will
correct this defect. These screws 38 are readily
accessible through openings 46, 46 located in the
block 44 at one side of the screws 42, 42. In ad
