A communication by Max E. BIERSACII, of Milwaukee, in the County of Milwaukee
and State of Wisconsin, United States of America, Mechanic.
I, JOSEPH JAMES ROYDEN, of the Firm of W. P. Thompson & Co., British and
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and G, Bank Street, Man-
chester, both in the County of Lancaster, 118, New Street, Birmingham, in the
County of Warwick, and 322, High Holborn, in the County of Middlesex,
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:
This invention relates to improvements in machinery for manufacturing that
class of fasteners known as seal holders, which consists of strips of metal, bent
and pointed at the ends, and which are used as label, stamp or seal holders, and
for a variety of similar purposes.
The object of the invention is to provide adjustable mechanism whereby the
seal holders may be bent, pointed, stamped, and separated from a strip of sheet
metal, in a single machine having co-operative and successively acting parts.
In the following description, reference is had to the accompanying drawings
in which

Like parts are identified by the same reference letters throughout the several
views.
A frame 1. is provided with a bed formed in two parts or blocks 2, 21, each
adjustably keyed to the frame by means of the downwardly projecting portions 3
(Figures 2 and 7) engaged in slots 4 and arranged to be locked therein at any
desired point of adjustment, by means of bolts 6 and plates 5, the latter being
arranged to engage the frame on each side of the slots, and adapted to form a
tparing for the head of the bolt. The parts 2, 21 of the bed are separated by
means of a right and left screw-threaded shaft 7 near each end, the lock bolts 6
being first loosened to permit the bed blocks to move in the slots 4. When

page_text: separated the parts are rigidly supported against vibration by means of wedges 8
which are forced upwardly between the blocks by means of screws 9.
The material from which the seal holders are made consists of a strip of metal 10
which is fed longitudinally over the bed between the feed rollers 11 into the path
of the forming tools, as hereinafter explained. The bed is adjusted in each case
to correspond to the width of the strip, that portion which extends between the
tools being of the same width as the body of the metal strip 10, between the base
of the serrations formed by the tools in the respective edges while that part of the
hed under the un-serrated portion of the strip 10 is preferably of the full width
of the strip, as originally fed into the machine.
The tool actuating shafts 12 and 121 are supported respectively from the bed
blocks 2 and 2¹ and actuated from the source of power through the drive wheel 13,
shaft 14, worm 15 and gear.wheels 16, the latter being keyed to the shafts.
The initial tool comprise the block-head 17, one on each side, which are keyed
to the actuating shaft and provided with recesses in their sides. The punches 18
are removably secured in these recesses by set screws 19 and a holding disk 20 is
removably secured to the recessed side of the head block and is adapted to afford
a lateral support for the punches. The punches are provided with tapered and
notched ends 21 which are adapted to register in counter-part notches in a die
plate 22, located in a recess in the bed. The edges of the strip 10 of the material
are engaged by the punches and cut to form teeth or points 23 as shown in
Figure 1, the material being moved forward intermittently as the teeth are cut.
The shafts 12, 121 are also provided with bender heads 24 (Fig. 8) provided with
sockets 25 in which are located arms 26, the latter having studs 27 which engage
in slots 28 in the head to retain the arms in the sockets, with springs 29 adapted
to hold the arms normally with the studs engaging the outer ends of the slots.
The arms are provided at their outer ends with anti-friction rollers 30 which
engage the points 23 formed by the punches in the material and bend them
downwardly as shown in Figure 1. After the points are bent downwardly, they
are creased or crimped longitudinally by means of a crimping punch 31 (Figs. 9
10) which registers with a die 32 screwed in the side of the bed, the punch
rod 31, being actuated by the roller 33 located in the outer ends of the arms 33
projecting from a hub 33. The rollers engage upon the curved plate 33d attached
to the outer ends of the rods 31ª. 35 are springs for retracting the crimping
punches, as soon as their supporting rods are released from the actuating rollers.
The material after leaving the punches, is passed under a printing plate 36
(Fig. 2) which is actuated as hereinafter explained, and over the shear bar 37.
38 is a separating knife, pivoted at 39 (Fig. 3) and provided with an extended
arm 40 which is connected by a retracting spring 41 with the floor or other suit-
able point of support, to hold the knife normally in a position with its edges
above the shear bar. A downward movement is intermittently communicated to
the knife from the shaft 12 through the eccentric 42 and roller 43, the latter
being supported on a trunnion projecting from the front end of the knife blade.
The downward movement of knife separates the seal holder from the strip 10
of material, cutting the same transversely between the successive points 23 which
are formed in its sides. The knife having completed its downward movement,
it is returned to its normal position by the retracting spring 41.
The motion of the knife arm 40 is communicated to the printing plate through
the adjustable connecting rod 44, lever 45, stud 46, vertically sliding plate 47,
spring 48 (g. 2) and supporting plate rod 49, the plate 47 being supported in
a frame 50 projecting upwardly from the bed. The lever 45 is provided with a
slot 51 (Fig. 3) in which the stud 46 engages, thus permitting the plate. to slide
freely in the bracket without cramping.
The motion of the lever 45 is also communicated to an inking roller 52 (Fig. 2)
through the stud 46, sliding plate 47, lug 53, link 54 and curved lever 55, the
latter being pivoted at 56 to the frame 50. With the extreme movement of the
lever 45 downward upon the lug 46, the printing plate 36 is forced downwardly

page_text: and the inking roller is carried outwardly over the rotary ink supply plate 57,
and with the reverse movement of said lever, the printing plate is raised and the
roller is carried under the same, to distribute the ink upon the type. While in
this latter position, the roller is given a short oscillatory movement by means of
intermediate projections 58 (Fig. 3) on the eccentric plate 42, which actuates
the knife and printing mechanism.
It will be observed that the various operating tools are arranged to act simul-
taneously and at regular intervals, but that their action is successive in relation
to any given portion of the strip. It is therefore necessary that the feed should
he intermittent, and for accomplishing this result, my correspondent has provided
the shaft 12 with an eccentric plate 59 (Fig. 4) which bears at intervals upon
the roller 60 located on one arm of an elbow lever 61, the motion of which is
communicated to the lower feed roller 11 through the rod 62, crank 63, pawl 64
and ratchet 65 as shown in Fig. 1, the motion being regulated by the proportion
of the parts to correspond in time with the intervals between the action of the
tools and in distance, to the width of the finished seal holder. 66 is a retracting
spring for withdrawing the rod 62 and its connected parts after the movement
caused by the eccentric plate 59 is completed.
All
It will be thus observed that the strip of material as fed by the feed rollers is
punched to form the tack points, the pointed ends bent by the rollers of the
bending heads, and crimped or dented by the denters, the uncut portion of the
material stamped by the printer, and then separated by the knife between the
successive points to form the completed seal holder, ready for the market.
the tools are actuated from the two shafts 12 and 121 in such a manner as to
co-operate each with the other in an intermittent simultaneous action upon the
various parts of the work The bed being adjustable my correspondent is enabled
to use the same device for strips of different widths by substituting feed rollers,
printing mechanism, cutting knives, etc., of the proper size to correspond with
the width of the strip and the size of the seal-holder to be formed.
Where it is desired to print the seal holders in two or more colors, a plurality
of printing devices is provided which are connected by a bar 70,--the latter being
secured to arms 71 of the lever 55. With this construction, the motion of either
of the printing mechanisms will be communicated to the other through the
arms 71 and connecting rod 70, as best shown in Figure 2.
It will also be observed that the strip of material is passed under pressure
rollers 72 which hold the material rigidly to the bed, while being operated upon
by the serrating, bending and denting heads.
