2 Claims. (Cl. 113-59)
This invention appertains to new and useful
improvements in seaming devices. of the lead
burning type.
The principal object of the present invention
5 is to provide a seaming device of the lead burn
ing type wherein a sup-port isafford‘ed for the
form iron, which will eliminate tedious exertion
on the part of the operator and which will allow
the form iron to be used by unskilled workmen.
Another important object of the invention is
to provide a device of the character stated
wherein the various parts can be readily ad
justed to meet the various demands for such a
These and various other important objects and
advantages of the invention will become appar
ent to the reader of the following specification.
In the drawings:
Figure 1 represents a front elevational view
20 of the apparatus.
Figure 2 is a side elevational View.
Figure 3 is a cross sectional view taken sub
stantially on the line 3-3 of Figure 1.
Figure 4 is a fragmentary detailed sectional
25 view taken substantially on the line 4-4 of Fig
ure 1.
Figure 5 is` a sectional View taken substantially
on the line 5-5 of Figure 3.
Figure 6 is a sectional view.
Referring to the drawings wherein like nu
merals designate like parts, it can be seen that
numeral 5 denotes an elongated I-beam along
the top flange of which is ridable the grooved
block 6 laterally of which extend the flanged
35 ‘arms '|--'I.
These arms 'I-l are provided with
vertical bores at their ends for receiving the up
standing posts 8_8 each of which is provided
cally adjustable shank Il of the form iron I8
which is pivotally secured to the member Il as
at I9. A coiled compressible spring 2i! is lo
cated in the barrel I6 and exerts tension down
wardly on the member Il and the form iron I8.
The barrel It is provided with openings through
which the retaining pin 23 is disposed, this pin
being disposed through a slot 2l in the member
Il as is clearly shown in Figure 3. The pin 2B
has a handle 22 at its outer end.
The arms 'I-l in the setting up of the device
are adjusted apart on the beam 5 to the desired
extent as suggested in Figure 1 and held in
these positions by the set screws 23.
Of course, the apparatus is used in a vertical
position as suggested in Figure 1 and in seaming
kettles and other receptacles the form iron I8
is lowered to the bottom of the receptacle. As
is well known, the lead sticks or strips are placed
in the form and melted by a blow torch. The 20
form iron is fed upwardly by rotating the hand
Wheels I4 and the seam is made continuous by
continuous dropping of the lead strip and ap
plication of the heat by a blow torch or the
While the foregoing speciñcation sets forth the
invention in speciñc terms, it is to be under
stood that numerous changes in the shape, size
and materials may be resorted to without de
parting from the spirit and scope of the inven 30
tion as claimed hereinafter.
Having described the
invention, what
claimed as new is:
l. A seaming apparatus of the character de
scribed comprising an elongated guide member, 35
a carriage carried by the guide member, a form
iron carried by the carriage, feed means between
with a pivotal suction cup- 9 at its lower end.
Set screws I0 are provided at the outer ends of
40 the arms 'I and these are feedable inwardly to
' engage the posts 8 to retain the posts in proper
the carriage and the elongated guide member,
adjusted positions with respect to the arms l.
elongated guide member, arms extending later
ally from the blocks, posts extending through the
It will be observed that such retention means
as this is provided at each end of the beam 5.
-45 In other words, there are two blocks 6 and two
sets of arms '1_1 as well as posts 8--8 and
cups 9_9. With this means the beam is sup
ported in proper position with respect to the
joint to be seamed.
A U-shaped carriage II receives the lower
flange of the I-beam 5 and short shafts I2-I2
are journaled through the upright flanges there
of. Each of these shafts I 2 is provided with a
gear I3 at its inner end and a hand wheel I4
55 at its outer end. Each lower flange of the I
beam 5 is provided with longitudinally extend
ing rack teeth I5 with which the corresponding
gear I3 meshes.
Depending from the bottom of the U-shaped
60 carriage Il is the barrel I6 receiving the verti
and removable supporting means for the said
elongated guide member, said supporting means 40
consisting of a pair of adjustable blocks on the
ends of the arms, detent means at the ends of
the arms for engagement with the posts, and 45
suction cups> at the work engaging ends of the
2. A seaming apparatus of the character de
scribed comprising an elongated guide member,
a carriage carried by the guide member, a form 50
iron carried by the carriage, feed means between
the carriage and the elongated guide member,
and supporting means for the elongated guide
member, said supporting means consisting of a
plurality of posts each provided with a suction 55
cup- at one end for engagement with the work
for holding the guide member to the work, and
adjusting means between the guide member and
each of the posts.
