Improvements in Armored Hose and Machines for Armoring
the same.
We, LEWIS ROBERTS, of 18 Wall Street, GEORGE CLINTON SCOFIELD of 72 Broad-
way, and JOSEPH ALLEN COULTAUS, of 49 Warren Street, all in the City and
State of New York, United States of America, Gentlemen, 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 the art of making Spiral Springs and the machinery for
manufacturing the same. It also relates to wire armored hose and the method of
armoring the same- -The object in each case being to reinforce the metal of which
the spring or armor is made instead of stretching it, as will be hereinafter explained.
Believing that we have created a new departure in the art of making springs we
have this day filed a separate application for a patent to cover the art itself We will
therefore confine ourselves as near as we can in this specification to the description
of the machine for armoring hose, and the product produced by the said machine and
we do not therefore wish to have any reference we inay hereinafter inake to the art,
or description thereof, considered as against or in any way as interfering with our
rights to a patent for the art.
In the accompanying drawings which form a part of this specification our invention
is fully illustrated in several figures with similar letters and numbers of reference to
indicate corresponding parts.
Figure 1. represents a plan or top view of our improved spring making machine
and-
Figure 2. is a face view of the same "in line" so that each figure fully illustrates
the position of the various gear wheels (designated by numbers ranging from one
to 16) and the manner in which they mesh with each other, in order that their
operation may be readily understood.
Figure 3. represents an outline side elevation showing the direction in which the
various gear wheels rotate, which is indicated by the direction of the arrows-also the
wire reel m. and the friction governor n. by which it is controlled.

page_text: Figure 4. represents a side elevation of the wire coiling tool or die a. secured
within the clamp c. by means of the strap b. and bolts d.
Figure 5. represents a perspective view of the same and
Figure 6. represents the rollers s. s. as forcing the wire è. within the die a. to show
more accurately their operation.
Referring to figures 1. 2. and 3. of the drawing it will be noticed that two sets of
gear wheels are operated by the same driving gear wheel number 1. one set operating
the rollers s. s. which force the wire e. within the die a. while the other set operates
the hose reel frames v. and w. as follows-
As shown in Fig. 3. the hand power driving wheel f. is rotated in the direction of
the arrow and being mounted on the same shaft as the geared driving wheel No. 1.
and belt wheel g. they must necessarily all revolve together-thus the machine can
be operated either by steam power or by hand as circumstances may require..
The driving gear wheel, No. 1. meshes with the large gear wheel No. 2. which
rotates in the direction indicated by the arrow-the large gear wheel 2. meshes with
a small gear wheel 3, the small gear wheel 3. meshes with a similar gear wheel 4.
which is located directly under, and meshes with the reel frame gear wheel No. 5. as
shown in figures 3. and 4.-Thus it will be seen from the direction of the arrows on
wheels 3. 4. and 5. that the gear wheel 5. which is secured to and operates the
frame v. rotates away from the machine-Gear wheel No. 3. is keyed to a shaft which
extends through the bed plate of the machine, and which has keyed to its opposite
end the gear wheel No. 12. which is a twin wheel to No. 3. and rotates exactly the
same-Gear wheel 13. is the same as gear wheel 4. and is mounted in a similar
manner on an independent shaft-Gear wheel 14. is mounted on the shaft which
carries the reel franie w.. in the same manner as the wheel 5. is mounted on the shaft
which carries the reel frame v. Thus it will be readily understood that the wheels 12.
13. and 14. being the same size and operated at the same speed as the wheels 3. 4.
and 5. the two reel frames . and w. must necessarily revolve together and alike.
Again referring to Figure 3, it will be seen that on the same shaft with the large
gear wheel 2. a small gear wheel No. 6. is mounted and secured so as to revolve with
the large wheel-The gear wheel 6. meshes with and rotates the gear wheel 7. which
in turn, meshes with and rotates the gear wheel 8. the gear wheel 8. meshes with and
rotates the gear wheel 9. which is mounted on the same shaft as gear whee! 10. and
the lower roller s. so that all three revolve simultaneously. Gear wheel 10. meshes
with gear wheel 11. which is mounted on the same shaft as the upper roller s. Thus
the two rollers s. are rotated so that their contact periphery s. are travelling towards the
die a. as shown in Figures 1. 3. and 6. so that when the wire e. is inserted within
the guide tubes u. and u. and between the rollers s. the said wire e. must be forced
within the die a. when the wheels s. are rotated as above described.
In order to cover hose or tubing in. this machine it becomes necessary that the
said hose or tubing should be revolved within the die to take up the wire as fast as it
is being forced therein-as will be hereinafter explained-It also becomes necessary
that the hose or tubing should be drawn through the die as fast as the pitch of the
spiral may require for this purpose therefore we have provided the gear wheels 15.
and 16. which are arranged to operate the worm gearing h. and i. all as shown in
Figures 1. and 2. as follows-
The two gear wheels are what may be termed sun and planet wheels, that is, the
gear wheel 15. is a fixed collar provided with a gearing on its periphery-The geared
wheel 16. is mounted on a shaft as't. which in turn is mounted on one side of the
frame w. so that when the frame w. is rotated by the gear wheels 12. 13. and 14. as
hereinbefore described-the planet wheel 16 will travel around the sun wheel 15.
Thus causing the shaft t. and planet wheel to rotate-On the opposite end of the
shaft t. the worm gear o. is mounted in a suitable manner to engage with the disc
worm gear wheel p. which is mounted on the shaft r. which carries the reel y. so that
as the worm gear o. rotates against the periphery of the disc gear wheel p. the said
disc wheel must revolve and necessarily cause the said reel to revolve in a like
manner-On the shaft ras-shown at l. is a coned plug or clutch which fits into a

page_text: circular cavity on the inside of the disc gear wheel p.-The spring j. which surrounds
the shaft . exerts its force against the clutch 1. so that the friction between the said
clutch and the disc wheel p. can be regulated by the nut k. thus the strain exerted by
the, reel y. to take up
"the hose as it is armored will depend to a great extent upon
the tension of the spring j¹. One of the most important features of this machine
is the die a. which is shown on an increased scale in Figures 4. 5. and 6.-This die
consists of a piece of flat steel or other suitable metal into which a hole is drilled the
requisito size at the upper edge of the hole a slot is cut so as to make an opening as
shown in Figure 4.
A flat strip of metal as shown at a¹. preferably brass, the width of which is regu-
lated by the diameter of the hole-or die-is soldered within the plate as shown in
Figures 4. and 5. on the inside of the brass a¹. a groove as shown at b. is cut running
in a spiral direction so that when the wire is forced within the die it will follow the
groove 61. and form a spiral around whatever substance may be within the die-The
method of securing the die in place is as follows-The die a. is arranged to slide in
grooves c. and c². provided in the clamp c. and is secured in place by the strap b.
which is placed over the die a. and screwed to the clamp c. by means of the
bolts d. d. The clamp c. in turn is screwed to the guide block A. which is arranged
to be adjusted either in a vertical or lateral direction so that the groove 6. in the
opening of the die as shown in Fig. 5. will be directly in front of the contact periphery
of the rollers s. and in line with the groove s¹. provided therein.
Another important feature of our machine is the wire reel m. and the manner of
regulating the supply of wire by means of the friction strap n. the reel m. is of any
desired construction and is mounted on a suitable shaft which is journaled to the ends
of the arms m³. ou one of the outer ends of this shaft a wheel with a smooth periphery
is provided and properly keyed-the strap o¹ has one end secured to the arm M!.
It then passes around the wheel w¹. and has its opposite end secured to the arm m'.
by means of a tension spring . thus the strap n. acts as a break or governor to
prevent the wire which is wound upon the reel (to feed the machine) from unwinding
itself from the said reel which it has a natural tendency to do.
Having herein before described the operation of the various gear wheels it seems
hardly necessary to redescribe them in considering the operation of the machine
I will only add therefore that the die having been placed in position as before
described the hose B. (to be covered) is wound upon a reel provided within the
frame v. and which is the same as the reel y. excepting that it is without the worm
gearing after the hose is thus wound upon the reel the end of the hose is passed
through the guide collar D and so through the die a. the machine is then set in
motion and the wire e. is forced by the rollers s. through the guide tubes u. and u¹.
into the die-the wire thus forced into the die will follow the groove b¹. as indicated
by the arrow in Figure 5. and will wind itself around the hose which is located
therein.
The most important feature of this method of creating a coil in the wire is the fact
that the spiral so formed has a tendency to contract and grow smaller rather than
expand and grow larger as is always the case where the coil is created by winding the
wire around a mandrel or arbor.
The hose or tubing therefore which is wound with wire by our machine is provided
with what may be termed a Sphincter grip spiral wire armor.-The hose is also
compressed by this method so that the strain is received and borne by the arbor and not
by the material of which.the hose is composed.
>>
After the hose has been covered far enough the end is secured to the reel
y. which
is automatically. revolved. by the gear wheels as hereinbefore described and "takes
the hose as fast as it is.covered.
up
It will be readily understood by any one skilled in the art that various forms of
dies can be made to take the place of the one which we have herein described and it
would not therefore fully protect our invention did we confine ourselves to that
particular form of die, as it is intended to use any die which reinforces the wire of
which the spring is made, and thereby creates the Sphincter grip.
