Another object is to provide for the conservation
of oil used in the machine, enabling its use in a
very simple manner.
The above features, and others contributing
to the e?iciency of the machine, will be apparent
from the following detailed description of a
preferred embodiment, as shown in the drawings.
In the drawings, Fig. 1 is a side elevation of my
pipe Working machine; Fig. 2 is a vertical cen
tral longitudinal section of the machine, on a
plane parallel with Fig. 1; Fig. 3 is a view look
ing at the right-hand end of the machine, as
30 shown in Fig. 1; Fig. 4 is a perspective of the com
bined carriage bed and motor housing; Fig. 5
is a vertical cross-section through the gear hous
ing, as indicated by the lines 5-5 on Fig. 2;
Fig. 6 is an elevation of a pipe threader which
may be employed, and which is shown in section
in Fig. 2.
Brie?y, the entire machine comprises a bed ID,
having a hollow standard 55, housing a reduction
gearing and carrying a driven chuck 20. A motor
.40 3d controlled by a switch ‘H3 is mounted on the
bed and connected with reduction gearing within
the housing l5; a supplemental bed 4!! carried
by the bed It! houses the motor 3!] and supports
a slidable carriage 8B, which carries the tools.
The tools shown comprise a threading device 9!]
and a cutter Hill.
Mounted on the side walls of
the supplemental bed 40 are removable containers
12!! for receiving the waste oil. These various
parts will now be described in detail.
The bed II] is a ?at member, shown suitably
coredv on its underside for lightness, and the
combined gear housing and chuck standard [5,
as shown, is integral with the bed except as to
a removable end plate l6 normally bolted in place.
At the top, this standard I5 is formed into a semi
face of the chuck. The motor has its armature
shaft 3| connected by a coupling 32 to a shaft
33 journalled in bearings mounted in the adjacent
face of the standard I 5. Shaft 33 is shown as
having a pinion 34 meshing with an idler gear 35,
which carries the pinion 3t meshing with a
second idler 31, carrying a pinion 38 engaging
main gear 25. This makes a direct train of spur
gearing fromlthe motor to the chuck, providing
the desired reduction.
Surmounting the motor is a peculiarly formed
casting 4B, which operates to house the motor and
also support the carriage. This casting is shown
in perspective in Fig. 4i. It comprises four pads
or feet 4! adapted to be bolted to the bed, two
feet on each side being connected by a vertical
web or side wall. At their upper edges the walls
42 extend outwardly as at 43 and then curve in
wardly and upwardly to form roof 5|. This roof
also curves downwardly at its ends and is thus
a shallow dome or “turtle-back.”
At one end
this turtle-back‘ unites with a horizontal por
tion 53. The horizontal ?oor portion 53 slopes
downwardly from the center as indicated at 515 to
cause oil, etc. to flow freely toward the sides of
the casting; at its outer edge the horizontal floor
53 terminates in an upwardly curving ?ange 55
which guides oil and chips toward the sides of 45
the casting. Suitable brackets 45 extend from
the turtle-back upwardly and are arranged to
support horizontal ?at strips 4'5 (Figs. 1 and 3)
which provide a slideway for the carriage. A
suitable transverse web 47 serves to brace the 50
tuctle-back and prevent oil from ?owing for
wardly of the‘front carriage supports 45.
It will be seen from Figs. 1 and 2 that the
casting 40 above described protects the motor,
entirely covering it above and at the front and 55
2,137,762

back, as well as at the right-hand end of the
machine, where the side walls 42 are connected by
a transverse web or end wall 48, Fig. 3. The web
48 has an opening to allow access to the motor,
but this may be closed by a cover plate, if de
sired. At the other end the casting 40 is open
for the purpose of ventilation.
It will be noted that the inner or left-hand
end of the casting 40 is spaced from the up
10 right housing I5 to provide for ventilation.
The
controlling switch ‘I0, Fig. 1, is secured to the
transverse plate of the standard I5 between such
standard and the end of the casting 40 and is
electrically connected with the motor so that the
15 latter may selectively rotate in either direction.
The carriage 80 is of the usual type, and rests
on the guides 46 of the supplemental frame and
is held thereto by suitable gibs 8| (Fig. 3) ex
tending beneath the overhanging edges of the
20 guides. As shown in Fig. 1, this carriage may be
of the ‘form shown in Patent No. 2,079,179, re
ferred to, having upright posts 82 which carry,
on the side toward the chuck, the threading de
vice 90, and on the opposite side, the cutter I00.
25 These parts may, if desired, be of the form shown
in the prior patent mentioned. As shown here
in, they will be briefly described later.
Suitable means are provided for moving the
carriage lengthwise of the bed. The means
30 shown comprises a centrally downwardly-facing
rack 85, which meshes with pinion 86 on a shaft
vided with a pair of bayonet slots I25 adapted
to receive respective headed pins I26 secured to
the side walls 42 of the supplemental frame 40,
thus facilitating the removal of the reservoirs.
The inner walls of each reservoir underlie the
horizontal portion 43 of the frame 40, the outer
edge of which depends slightly as indicated in
Fig. 4, at 52, thus insuring the draining of all
oil into the reservoirs.
The used oil, together with the discharged 10
chips and dirt will pass downwardly from the
turtle-back 40 into the receptacles I20. From
time to time the receptacles will be removed and
the dirt and chips removed therefrom, then the
relatively clean oil may be poured from the re 15
ceptacle, for instance, into a supply reservoir
I30, mounted on a post I3I on the carriage.
From this. reservoir oil is discharged to the tools
through a pipe I35, controlled by a cock I36.
It will be seen from the description given that 20
by employing the peculiar supplemental frame
shown and described, I have thoroughly pro
tected the motor, and allowed provision for ven
tilation thereof. At the same time, I have pro
vided means for readily retrieving the waste oil 25
and restoring it to condition for using. The re—
movable receptacles enable ready transfer of the
oil to the supply reservoir without the necessity
81 journalled with bearings 61 carried by the
of employing a pump, thus rendering the whole
30
machine less liable to get out of order.
I claim:

guide bars 46. A suitable hand wheel 88 fur
nishes means for rotating the shaft to shift the
35 carriage toward and from the chuck, as desired.
engagement with a pipe mounted in the chuck, 35
Referring to Fig. 6, 90 indicates a suitable
ring-like frame carrying radial chasers 9| to
coact with the pipe A. The ring 90 is shown
as having diametrically opposite horizontal ears
40 92, which seat in ways in the carriage posts and
may be held in place by tapered pins 93. As
shown, the ring frame 90 carries a face plate
95 having internal cam grooves coasting with
pins on the chaser. The ring carries a crank 96
45 operated by hand lever 91 and adjustably con
nected by a link 98 to the cam plate.
Accord
ingly, the throwing of the lever may spread the
chasers or return them, if desired.
The cutter is illustrated in the drawings as of
50 the form shown in the patent referred to,
although another form of cutter may be used,
if desired. Briefly, in the form shown, the cutter
comprises a slidable block IOI (Fig. 3) mounted
on one of the carriage posts and carrying a cut
55 ting wheel I02. Opposed to this is a slidable
block I04 carrying a pair of rollers I05. Rods
I06 attached to the block I04 pass slidably through
ears on the block IOI to a head I01. Rotatably
mounted in this head is _a screw-threaded shaft
60 screwing into the block IM and carrying on its
free end an operating hand wheel I09. The
turning of this hand wheel may therefore force
the blocks toward each other or cause them to
recede, as desired.
65
In Figs. 1 and 3, I20 indicates open top con
tainers which are removably supported by and
rest against the respective side walls 42 of the
supplemental frame 40, the inner side edges of
the container coming beneath the overhanging
70 horizontal walls or beads 43 of the frame.
Chips and oil dropping from the tools slide off
the turtle-back 5| and drop into the containers.
Each container may be provided with the usual
removable screened basket, not shown.
