A communication from abroad by SAMUEL KIRKBRIDE WILSON, Manufacturer, a
citizen of the United States of America, residing at the corner of Cooper and
Factory Streets, in the City of Trenton, County of Mercer, and State of New
Jersey, United States of America.
I, PETER JENSEN, of No. 77, Chancery Lane, London, Chartered Patent Agent, 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: —
Referring to the accompanying drawings——

This invention has relation to hose machines, and is designed to provide a
simple, efficient, and practical machine for the manufacture of long hose, although
equally well adapted for the purpose of making short hose or hose sections.
The invention relates more particularly to means for supporting the hose pole or
mandrel, and to means for driving the same; to means for insuring a perfectly
solid and uniform winding of the duck or other material used. in the manufacture;
also to means for regulating and controlling the pressure of the wrapping and
winding devices; also to automatic mechanism for throwing the mandrel-driving
mechanism. into and out of operation at the proper times.
The invention also consists in the novel construction and combination of parts,.
all as hereinafter described and pointed out in the appended claims.
Referring to these drawings, the numeral 1 designates the frame of the machine,
which is of a length somewhat greater than the length of the longest piece of hose
which can be made upon the machine, which in the machines heretofore built by
me, is fifty feet. 2 is a stationary shaft, which is held and supported in hangers 3,
and which extends nearly the full length of the machine. This shaft may be
squared throughout its length as shown, or it may be squared only where it enters
the end hangers 3. Secured to the said shaft throughout its length by means of
sleeves 4 are two series of forwardly extending spring arms 5 and 6. Each of these
arms has a fork 7 at its forward end, and journalled in each fork is a roller 8 or 9,

page_text: of steel or other suitable material. These two series or lines of rollers lie adjacent
to each other in the same horizontal plane, and are parallel.
10 designates a rock-shaft, which is supported above the shaft 2, and parallel
therewith, in boxes 11, which are secured to the frame 1. Secured in said rock-
shaft at intervals throughout its length are sleeves 12, and to each of these sleeves
is secured an upwardly curved forwardly extending spring arm 13, having a fork 14
at its forward end, in which is journalled a short roller 15. The line or series of
rollers 15 when in operative position, lies above and centrally of the rollers 8 and 9,
as best shown in Fig. 3. Connected to said rock-shaft are rearwardly extended
counterweighted arms 16.
17 designates a short driving shaft which is journalled in boxes 18 at one end
portion of the machine upon a forward extension 1" of the frame. 18 and 18b
are belt pulleys on said shaft. 20 is an endwise-movable clutch coupling section,
which is mounted on the inner end of the shaft 17 to rotate therewith, and which is
designed to engage with an opposing section 21 on the end of a shaft 22. The
shaft 22 is journalled in a long box 23, and is provided with two universal joints 23"
and 24. The end section 22" of the shaft 22 is journalled in a box 25 which is
vertically adjustable in guides 26 of a frame piece 27, and which is adjusted by
means of a screw 31. On the end of said end section 22" is a chuck 28, in which
is designed to be secured one end portion of a hose pole or mandrel. This hose pole
or mandrel is secured at this end only, and is supported and carried upon the two
lower series of rollers 8 and 9, upon which it, rests. By means of the universal
joints 23 and 24, and the vertically-adjustable box 25, said chuck and the mandrel
can be adjusted to suit the particular diameter of hose being made.
Secured to the rock-shaft 10 at the driving end portion of the machine, is a rigid,
forwardly-extending arm 31, which terminates in a hook 32. Journalled on the
frame extension 1" below the shaft 17, is a short shaft 33, having a belt pulley 34,
which is driven by a belt 35 from the pulley 18b on the shaft 17. At its opposite
end from the pulley 34, this shaft 33 is extended beyond the frame extension 1°,
and has a bearing at 35" in the frame, above referred to. On this extended portion
of the shaft 33, is an endwise movable clutch section 36, which turns with the said
shaft; and adjacent thereto is a loose clutch-section 37. Adjacent to the section 37
is a loose pulley 38, having a boss 39. Placed around the pulley 38 is a friction
band 40, having opposite lugs or projections 41; and on the clutch section 37
are lugs 42, which are designed to engage these lugs or projections of the friction
band (see Figure 6). Connected at one end to the boss 39 of the pulley 38, is a
band or strap 43, which passes underneath a pulley 44, journalled in a bracket
secured to the floor, adjacent to the machine. From this pulley the said strap or
band extends upwardly to the hook 32 of the arm 31, which it engages by means
of a loop or ring.
Arranged as thus described, the clutch section 37 is driven by the engagement
therewith of the clutch section 36, and the pulley 38 is driven by the engagement
of the lugs of its friction band with the lugs of the section 37, thereby winding the
band or strap 43 on the boss 39 and pulling down on the arm 31. This actuates the
rock-shaft 10 to bring the rollers 15 into operative position with respect to the
mandrel, and also to put said rollers or their carrying arms, under tension. When
however further movement of the arm 31 is stopped by a device hereafter described,
the band 40 will slip on the pulley 38, and the latter will remain idle until the
tension is relieved. The clutch section 36 is thrown into engagement by means
of a treadle or foot lever 45, fulcrumed at 46, and which has a forked arm 47, which
engages the grooved hub of said clutch section. A spiral spring 47 is arranged to
move said clutch section 36 in the opposite direction when the. foot is removed
from the treadle.
.
In the operation of the machine, it is extremely important that the mandrel
or hose pole shall not commence to rotate until the rollers 15 have been brought
into operative relation thereto, and properly tensioned. I have accordingly devised
means whereby the mandrel remains stationary until these rollers have been

page_text: brought to position and tensioned, and for then automatically throwing the
driving devices for said mandrel into operation. These devices will now be
described.
Supported on the frame 1, at the driving end of the machine is a frame 50, having
upright arms 51, provided each with an elongated vertical slot 52. Resting in these
slots is a rod 53, having at one end a forked arm 54 at right angles thereto, which
engages the grooved hub of the clutch coupling section 21 on the shaft 17.
Coiled around the said rod and bearing against one of the arms 51 at one end and
against a collar 55 on said rod at its opposite end is a heavy coiled spring 56.
The collar 55 has a projecting pin 55". 57 is a lever which is fulcrumed to the
frame 50 at the point 58, and which has at one end a vertical arm, which engages the
pin 55" of the collar 55. At its opposite end said lever has jointed thereto a
vertical arm 60. The arm 60 is connected at its upper end to a lug or projection 61
of the arm 31 of the rock-shaft 10. 62 is a rod which is pivoted at one end at 63
to the frame 50, and which extends obliquely and upwardly towards the opposite
end of said frame passing through the slot in one of the upright arms 51, and also
through a slot in the arm 60, its bent end portion extending underneath the
lug 61 of the arm 31. 64 is an adjusting screw which is seated in the said lug
and is adapted to contact with the underlying end portion of the said rod 62.
65 is a spring which supports the said rod 62. 66 is a catch projection on the
rod 62, which is designed to engage a similar but reversed projection 67 on
the adjacent portion of the rod 53." 68 is an adjusting screw, which is seated in
the arm 31, and which is adapted to contact with the shaft 2 to limit the
downward movement of the arm 31.
The operation of the machine is as follows:-
The hose pole or mandrel with the inner tube or lining of the hose slipped thereon
is secured in the chuck 28 at one end and rested on the two lines or series of short
rollers 8 and 9. The foot is then pressed on the treadle 45, which throws the
clutch section 36 into engagement with the section 37, thereby setting in motion
the pulley 38, and winding the strap 43 on its boss 39. This draws down the
arm 31, rocking the shaft 10 forwardly and thereby brings the rollers 15 into
contact with the mandrel, or with the tube or lining thereon. The set-screw 64
as the said arm 31 approaches the limit of its downward movement, comes into
contact with the underlying end portion of the rod 62. This contact depresses the
said rod 62 and thereby releases the catch engagement 66 and 67 between said rod
and the clutch-shifting rod 53, which engagement had theretofore been holding the
said rod 53 against endwise movement under the action of its spring. As soon as
rod 53 is released from such engagement, it moves endwise and brings the clutch
coupling 20 into engagement with the coupling section 21, and thereby sets the
mandrel in motion. The strip of duck or other wrapping material has previously
been stuck at one edge to the inner tube or lining on the mandrel, and is now
wound thereon by the rotation of the mandrel, the winding being made uniform
and smooth by the action of the short rollers. In order to prevent joints or breaks,
and to provide a continuous bearing of these rollers, the latter are made to break
joints with each other; as shown in Figure 1. The pressure of the rollers is
regulated by the screw 68. When the lever 31 comes to the proper position to give
the desired degree of pressure, this screw comes in contact with the shaft 2. The
pulley 38 then ceases to turn and the pressure is held at this degree. As soon as
the hose is wound, the foot is removed from the treadle 45, and the spring 47
moves the clutch section 36 out of engagement with the section 37. The counter-
weighted arms of the rock-shaft now rock said shaft backwardly, raising the entire
line of rollers 15 away from the mandrel. As the arm 31 rises, it pulls on the
lever 57, and causes the vertical arm thereof to engage with the pin 55% of the
collar 55, thereby moving the rod 53 to throw the clutch coupling section 20 out
of engagement and thereby stop the rotation of the mandrel. This action also puts
the spring 56 under tension, and brings the catches 66 and 67 again into engage-
ment ready for the next operation.

page_text: Owing to the length of the rock-shaft 10, and in order to secure a more uniform
pressure of all the rollers throughout the series, treadle levers 70 are provided at
intervals. These levers are arranged as shown, to act upon the said rock-shaft at
its intermediate and distant portions.
The duck employed in the wrapping is usually formed of bias strips having their
selvedge edge portions overlapped, thus making the material of double thickness at
these portions.
Heretofore it has been very difficult, if not impossible to secure a perfectly
smooth and uniform wrapping, owing to the fact that these double thick portions
take the pressure of the rollers to the exclusion of the intermediate portions. By
means of the series of short, independently yieldable rollers, I am enabled to over-
come this difficulty. I am also able to make good hose on a bent or crooked
mandrel or hose pole.
It will be obvious that short lengths of hose may be made on the machine as
well as long hose.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The herein described machine for the manufacture of hose, consisting of the
series of yielding mandrel or hose pole supporting rollers, the upper series of
pressure rollers, the mandrel-driving devices, and the automatic clutch operating
devices for bringing the mandrel into operation at the proper times, substantially
as described.
2. In a machine for the manufacture of long hose, the two series of short
mandrel or hose-pole carrying rollers, and the upper series of yielding pressure
rollers, and the devices for putting the same under tension, substantially as
described.
3. In a hose making machine, the mandrel driving devices, the supporting and
carrying rollers, the pressure rollers, the devices for putting said rollers under
tension, and for regulating such tension, and the automatic clutch-operating
mechanism for starting the rotation of the mandrel after the pressure rollers are
positioned and tensioned, substantially as described.
4. In a hose making machine, the two series of yielding mandrel-carrying and
supporting rollers, the counterweighted rock-shaft carrying a series of spring arms
to which a third series of rollers are journalled, the jointed mandrel-driving shaft,
the clutch and friction devices for positioning and tensioning the said rollers and
the clutch and its automatic operating devices whereby the mandrel is put in
rotation after said rollers are positioned and tensioned with respect thereto,
substantially as described.
