3. Claims. (CI. 81—41)
My invention relates to a new and useful pipe
cutter’s collapsible bench and has for one of its
objects to construct an exceedingly simple and
effective knock-down structure that may be easily
5 assembled and also readily disassembled for trans
portation in a relatively small space.
Another object of the invention is to provide
unique means for detachably connecting the
bench legs and their associated braces to the
10 bench top.
A further object of the present invention is to
so associate the parts of the device that when
in use it will be rigid, strong and durable al
though relatively light in weight, and inexpen
15 sive to manufacture.
A still further object of this invention is to
provide means for supporting some classes of
work and tools on the bench.
With these and other objects in view, this inven
tion consists of the details of construction and
combination of elements hereinafter set forth
and then speci?cally designated by the claims.
In order that those skilled in the art to which
this invention appertains may understand how to
make and use the same, I will describe its con
struction in detail referring by numerals to the
accompanying drawing, in which ;—

Fig. 10 is a view of the underside of the bench
In carrying out my invention as herein em.
50 bodied l5 represents the bench top having a pair
of lock keepers l6 mounted on the underside
adjacent both ends thereof and said keepers are
in endwise alignment. These keepers have T
shaped slots, Fig. 5, each open only at one end
55 and the keepers at one end of the bench top are
preferably reversed relative to those at the other
end of said bench top». One of each pair of keep
ers has a hole ll in its top wall through which
a pin 18 projects and this pin is carried by a bar
l9 mounted in a recess 20 in the under face of UK
the bench top and of sufficient size to permit the
bar to be moved in and out and also accommodate
a spring 2| which urges the bar and pin out
ward. Said spring has one end set in a socket
22 and the other end is telescoped over the inner 10
end of the pin 18 which projects above the bar.
Said bar 19 is loosely held in place by a screw 23,
the head of which is smaller than the counter
sunk hole 24, Fig. 6, into which the screw head
projects. This arrangement allows the bar to be
actuated in one direction by the spring and in the
other direction by pressure upon the ?nger piece
25 on the free end of said bar. The outer end of
the pin I8 is beveled to cause said pin to be re
tracted when a member, to be presently described d
is forced into the keeper.
An A-shaped leg pedestal 26 is provided for
each end of the bench top to support the latter
and each pedestal includes two legs 21 of pipe
connected at their upper ends by elbows 28 to a 25
cross bar 29 which is also pipe. The elbows are
clamped in place by fastening means 3!], such as
bolts and nuts and the pipe elements are held
against rotation by set screws 3|. Three of the
elbows are identical in construction but one of 30
them. at the end of the bench where the vise is
located, has a web 32 from which projects a pair
of spaced hooks 33, Figs. 8 and 9 to form a hanger
for a pipe cutter.
The legs 27 are braced near their lower ends
by a. spreader 34 of pipe having its ends con
nected to sockets 35 clamped onto the legs. The
feet 36 for the legs are also sockets having toes
31 formed thereon.
On the cross bar 29 are clamped the locks 38 v4:0
having heads T-shaped in cross section attached
by the fastening means 39 and heldagainst rota
tion by set screws 40. These locks 38 are spaced
the same as the keepers I6 which latter are
spaced at least a distance sufficient to permit one
of the locks to pass between them. When the
locks 38 are properly registered with their keepers
l6, said locks may be slipped into said keeper
through the open ends and when in place the pin
l8 will enter a hole 4| in the head of one of the 0
locks, Fig. 5 to hold the leg pedestal against
accidental displacement. By pressing upon the
?nger piece 25 to move the bar I9 in opposition
to the spring the pin l8 will be retracted to
release the locks.
The spreader bar 34 has a ?anged socket 42
at both ends with a strap 43 rotatably mounted on
each between the flanges and to each strap is
pivoted a one-eye socket 44. Each socket 44 has
one end of a brace element 45, which is a section
of pipe, attached thereto and on the opposite end
of each brace element 45 is mounted a two-eye
socket 46. The brace elements converge toward
their upper or outer ends and their sockets 46
H) are pivoted at 41 to the companion piece or con
necter 48. To this connecter is hinged the brace
lock keeper 49 having keeper openings 55 and
a hole 5|.
The brace lock keeper is adapted to be placed
over the hook shaped lock bolts 52 on the brace
lock plate 53 until said lock bolts pass through
the openings 59, then the keeper 49 is moved
lengthwise until portions of said keeper overlap
the tangs of the lock bolts. There are two lock
20 bolt plates, one for each brace structure and they
are secured to the under face of the bench top
between the ends of the latter and are positioned
reverse to each other.
Within a recess 54 in the underneath face of
the bench top, above each brace lock plate 53
is a lock bar 55 anchored at one end by a screw
56 with sufficient “play” to permit the other end
of the bar to move in and out. This method of
mounting is the same as that described in con
nection with the lock bar 19. The free end of
the lock bar 55 carries a pin 51 which projects
through the plate 53 to one side of the lock bolts
52, Fig. 10, and is urged outward by a spring 58,
Fig. '7, so as to enter the hole 5! when the latter
is moved into registration with the pin. Said
lock bar has a ?nger piece 59 which projects be
yond one end of the plate 53 whereby the lock
bar 55 may be moved inward against the action
of the spring 58 for retracting the pin '51.
To assemble the bench, the top I5 is turned
upside down, then the T-shaped lock bolts 38
of the leg pedestal 26 are inserted in the keepers
l6 and moved sidewise, relative to the bench top,
until'the pins l8 enter the holes 4i. Because of
the ?exible construction of the brace structures
they may now be shifted about until the brace
lock keepers 49 can be passed over the hook
shaped lock bolts 52 which register with the
keeper openings 50. Said brace lock keepers 49
50 are then moved longitudinally until portions
thereof overlap the tangs of the hook shaped lock
bolts. and the pins 51 enter the holes 5| in the
brace lock keepers. The brace structures are
now held rigidly in place and the whole assembly
65 is supported in an efficient manner for the pur
pose for which it is particularly adapted.
To disassemble the bench the brace structures
cation where it is to be used and then quickly
assembled on the job.
Of course I do not wish to be limited to the
exact details of construction herein shown and
described as these may be varied within the scope
of the appended claims without departing from
the spirit of the invention.
Having thus fully described my invention what
I claim as new and useful is:
1. A pipe cutter’s collapsible bench comprising 10
a bench top, a pair of keepers mounted on the
under face of the bench top adjacent each end,
each of said keepers having a T-shaped slot open
at one end, the keepers at one end of the top
being in reverse position to those at the other 15
end, a lock bar mounted in a recess in the un
derside of the bench top above one of the keep
ers of each pair, a pin carried by the lock bar
and extending above and below said bar, a spring
seated in the recess and positioned about the up 20
per end of the pin to urge the lock bar and pin
outward, leg pedestals including a cross bar, a
pair of lock bolts with T-shaped heads secured
to the cross bar of each pedestal for sliding in
sertion into the keepers, one of said heads hav 25
ing a hole to receive the pin for releasably hold
ing the lock bolts in their keepers, brace struc
tures carried by both leg pedestals, and means
to detachably connect said brace structures to the
underside of the bench top intermediate the ends
of said top.
2. In a device of the kind described, a bench
top, a leg pedestal detachably fastened to the
underside of said top adjacent each-end there
of, a spreader on each said leg pedestals, brace 35
structures each including two leg members rotat
ably connected to a spreader, connecting mem
bers to which the leg members of the brace
structure are pivoted, lock keepers having bolt
receiving openings and a hole, said keepers be 40
ing hinged to the connecting members, hook
shaped lock bolts secured to the underside of
the bench top for registration with the openings
in the keepers when the latter are placed over
the bolts, said keepers being movable longitudi
to support said top, each pedestal comprising leg
members, elbows on the upper ends of said leg
members, a cross bar having its ends mounted in
the elbows, fastening means to clamp the elbows 55
in place, sockets having toes mounted on the
lower ends of the leg members, other sockets
are ?rst disconnected from the bench top by re~
clamped on the leg members adjacent their lower
tracting the pins 5'! to allow the brace lock
60 keepers 49 to be disengaged from their lock bolts
52. Next the pins iii are retracted and. the lock
bolts 38 withdrawn from their keepers I6. The
ends, a spreader secured to the last named
sockets and ?anged sockets attached to the
spreader, straps rotatably mounted on said
fastened by means of a hook 6| on the chain '85
to another chain 62 ?xed to the other fastening
bench top, and means on the underside of said
respective leg pedestals and held in place by
65 a' chain 60 which is ?xed to one of the fastening
means 30 on one of the elbows 28, saidchain
being passed around one brace element 45 and
flanged sockets, single eyed sockets pivoted to
the straps, brace members having their lower
ends in the one eyed sockets, two eyed sockets
mounted‘ on the upper ends of the leg members,
a connector to which the two eyed sockets are
pivoted, a keeper hinged on the connector, means
to detachably connect the leg pedestals to the
brace structures are then folded up‘ against their
means 30 on the same elbow.
A bench constructed in the manner herein set
forth is strong and durable but may be readily
knocked down and easily transported to the 10
nally to engage portions thereof over the hook
shaped lock bolts, lock bars in recesses above the
lock bolts, pins on lock bars for projection into
the holes in keepers, and springs to urge the lock
bars and their pins outward.
3. In combination, a bench top, leg pedestals
