the
The machine which is designed for the finishing of brass fittings such as cocks,
valves, and the like, by subjecting them to the action of cutters such as reamers,
taps and dies may, in a general way, be said to consist of a central monitor head
provided with work holding chucks for presenting a number of pieces, in this instance
six, of the work to the simultaneous action of as many radial and horizontal mandrels
carrying cutting tools which are simultaneously advanced to do their work upon
fittings, which are held stationary, and then are retracted. After the retraction of
the mandrels the monitor is partially and automatically rotated and at proper times
by the same action the work-holding chucks are partially rotated so as to present
another side of the six pieces of work to the next advance of the mandrels, and
so on. Thus it will be seen that each piece of work is brought successively
under the action of each of the cutting tools until all of the sides have been
acted on, whereupon the chuck carrying the finished piece of work is brought
opposite a place where there is no mandrel and the finished piece is removed
and a fresh casting put in its place to be dressed in the same manner.
With
the exception of the introduction and removal of the fittings all of the move-
ments of the machine are automatic and its operation is continuous.
With this preliminary description of the machine, I will now proceed to
describe how it is constructed and how it operates.
A, Figs. 1, 2, 3, and 4, is a central vertical tubular post or standard made
rigid to a surrounding polygonal table of frame-work B, properly braced and
supported and with a gap or opening at one side, as seen in Fig. 2. Upon the
top of the post A, see Fig. 4, is rigidly secured a head block C, upon which
rests and intermittently rotates the monitor head D to which are secured the
work carrying chucks hereinafter described.
Set horizontally and radially upon the table or secured thereto are the head
stocks E, Figs. 2 and 4, in this instance, six in number though there may be
more or less as desired. In each of the head stocks is journaled so as
to be free to slide therein a horizontal mandrel F radial to the monitor-
head. These mandrels are simultaneously rotated, see Figs. 2 and 3 in the
following manner: G is the main horizontal driving shaft journaled in the table
and in an outer supplemental frame H. Loosely journaled upon the shaft
between the table and frame H are the cone driving pulleys I and gear J rigidly
secured together. The gear J meshes with the larger gear K, Fig. 2, upon a
counter shaft which carries a smaller gear L meshing with a larger gear M fast
upon the shaft G. Also fast upon the shaft G by the side of the table is a
gear N. The shaft G, it will be observed, is between and equidistant from two
of the mandrels and the gear N meshes on one side with a train of gears, the
last of which meshes with a gear a feathered upon each of the mandrels.
As
the three sets of these gears for revolving all the mandrels are duplicates of each
other and bear the same letters of reference, I would thus describe them
referring to Figs. 1 and 2 and looking towards the center of the machine. On
the right the gear N meshes with a gear O journaled upon a stub shaft band
carrying a larger gear P meshing with a smaller gear Q journaled upon a stub
shaft and carrying a larger bevelled gear R meshing with a bevelled gear S
journaled upon a stub shaft d and carrying a gear T, Figs. 1 and 4, meshing
with the feathered gear a upon the right hand mandrel F.
On the left gear N meshes with a smaller gear U journaled upon a stub
shaft e and carrying a larger gear V meshing with a smaller gear W journaled
upon a stub shaft and carrying a larger bevelled gear X meshing with a
bevelled gear I journaled upon a stub shaft y and carrying a smaller gear Z,
see Figs. 11, 12 and 13 which meshes with a gear A¹ journaled upon a stub

page_text: shaft projecting from a bell-crank-plate shifter i hung at its lower end from
the shaft and carrying upon a second stub-shaft ja gear B' constantly meshing
with the gear A¹. As the bell-crank s is shifted by means to be presently
described, either the gear A' or the gear B₁ is caused to mesh with the.
feathered gear a upon the mandrel D to reverse its direction of revolution.
While the shaft G directly rotates the two mandrels between which it is
located it will be observed that there are two other radial shafts G¹ and G³,
Fig. 2, each between a pair of mandrels and carrying at their outer ends gears
meshing with trains of gears such as previously described for revolving said
mandrels. Each of the shafts G, G¹ and G' has fast upon its inner end a
bevelled gear C¹ meshing with a superimposed bevelled gear D' journaled upon
the post A just above the table, see Figs. 3 and 4, so that the rotation of the
shaft G is imparted to the shafts G and G, as will be readily understood.
Having described how the mandrels are revolved I will now describe how
they are, with the tools carried upon their inner ends, simultaneously advanced
to act upon the work carried by the monitor head and then simultaneously
retracted.
Referring to Fig. 3, it will be seen that there is a gear E¹ fast upon the
shaft G between the gears M N which meshes with a subjacent larger gear Fl
journaled upon a counter shaft k and carrying a smaller gear H¹ meshing with
a larger gear I upon the outer end of the horizontal shaft J journaled in the
table and in a supplemental bearing frame 1. Fast upon the inner end of the
shaft Ji a disk K¹ having a crank or wrist pin m confined in a horizontal
slot n, see Fig. 6, in a lateral extension secured to the lower part of the
sleeve L' free to slide vertically upon and surrounding the post A. It will be
seen from this construction that the revolution of the shaft J₁ causes the vertical
reciprocation of the sleeve L' upon the post A.
Pivoted to lugs p upon the upper end of the shaft L' are links q, six in
number, and each having its lower end pivoted to the lower end of each of six
levers, see Fig. 4, each of which is pivoted as at in its head stock E and
has its upper end forked and surrounding the mandrel though without touching
the same.
""
Pivoted between the upper forked ends of each of the levers is an arm t having
its outer end bent down, forked, and pivoted to a loose collar u held adjustably by
nuts on the threaded end of each mandrel. It results from this construction
that as the sleeve I' ascends the upper ends of the levers are thrown outward and
the mandrels F with their tools are retracted, and when said sleeve descends the
upper ends of the levers are thrown inward and the mandrels are advanced inward
to bring the cutters and taps in contact with the work.
By
I will now describe the mechanism for automatically reversing the direction of
revolution of these mandrels which carry taps of which three are shown in the
Those
present machine alternating with those carrying cutters or reamers.
mandrels carrying cutters or reamers do not require to be reversed as they are
being retracted but those carrying taps do; as will be readily understood.
reference to Figs. 8, 9, 11, 12, 13, 14, 15 and 16 this reversing mechanism will be
readily understood from the following description: In guides a', Fig. 11, on one
side of the head-stock E is fitted a sliding horizontal latch piece & whose outer
end engages under a nose c¹ of the bell-crank shifter i to hold the same up with the
gear B in mesh with the feathered gear a of the mandrel and with the gear A' out
of mesh with a, see Fig. 12. In this position a coiled spring connecting the
nose of the shifter i and a fixed part of the frame, as the base of the head stock,
is put under tension. An upwardly extending arm e', Fig. 11, adjustably
secured to the latch piece is rigidly secured to a horizontal rod f' guided in a
housing g¹ upon the head stock. A coiled spring surrounds the rod f¹ between
the housing and the arm e¹ and upon the forward end of the rod f' is adjustably
secured a collar with which, just before the completion of the inward travel of
the mandrel and its tap, the forked end of an arm j¹, Fig. 8, carried by the
g

page_text: mandrel comes in contact and, locking the rod f¹ to the mandrel, draws the rod
inward putting the springs ' under tension and withdrawing the latch from under
the nose c of the gear shifter i¹. As soon as this takes place the spring d¹ being
released draws down the bell-crank shifter to the position in Fig. 13 and throws
gear B¹ out of mesh with gear a and brings gear A¹ into mesh with a thereby
reversing the direction of revolution of the mandrel and tap, as will be readily
understood. This withdrawing of the latches of those mandrels which are provided
with the same takes place just as the upper parts of the levers begin their back-
ward travel. In the meantime the end of the latches. are held against the inner
sides of the nose c' and the springs are kept under compressed tension.
2
Pivoted as at k, Fig. 8, upon the opposite side of each head stock having the
reversing mechanism is a horizontal bell-crank lever 1, Fig. 15, whose outer end is
connected by a pivoted link m¹ with a guided slide n having a pin o¹ engaging a
perforation p', Fig. 14, in the shifter i, and the parts are so adjusted that, just
before the upper parts of the levers reach their extreme outward throw and just
before the mandrels are entirely retracted, thereby, the inner end of the bell
cranks are engaged by the levers and the former are tipped, thereby, through
the medium of the links m' and slides ', drawing back the shifters bringing them
to the position of Fig. 12 and bringing the gears B' again into mesh with the
gears a and so again reversing the direction of revolution of the tap-carrying
mandrels. As soon as the gear shifters have been thus drawn back to the position
of Fig. 12 the springs h' are released and throw the latches 1 under the noses c¹ of
the shifters to hold the latter locked until the latches are again withdrawn as
above explained. In this manner the tap-carrying mandrels are revolved to the
right as they are advanced to act upon the work, and having cut their threads to
the proper depth they are reversed automatically and revolved to the left as they
are being retracted. This mechanism is not necessary with the mandrels having
cutters or reamers, as before explained, and they can continue to revolve con-
tinuously in the same direction as they are advanced and retracted. I will now
proceed to describe the construction of the work-carrying chucks illustrated in
Figs. 4, 23, 24, 25, 26, 27, 28, 29 and 30, of which there are vertically secured to
and bolted to the monitor head always one or more than the number of mandrels
in the machine, for a purpose to be hereinafter explained.
The body of the chuck is composed of a vertical ribbed portion and a rearwardly
projecting centering pin which is confined in one of the bores of the monitor
head and clamped by a set screw s', see Fig. 4, while a second set screw t¹ is passed
through a rib on the upper rim of the monitor head into the upper vertical
portion . Upon the ribs of the body portion q' are two vertically adjustable jaw
carriers the former for the upper and the latter for the lower jaw. Pivoted
as at w, Figs. 26, 28 and 29, between two plates a bolted to the top of the
portion q are two half nuts 2 whose forwardly projecting threaded ends normally
engage a screw 2 whose lower end is fast to though free to turn in the upper jaw
carrier and whose upper end is provided with a handle d². In a rearwardly
extending cross piece carried by a screw 2 just beneath the handle is carried the
upper end of a rod f', provided at its upper end with a handle y² and recessed so as
to be free to slide vertically on the portion 9. This rod is polygonal in section
and passes through a hub journaled in and between the plates a² and between
the rear ends of the half nuts. The hub is shaped to act as a cam upon hooks i²
fast to the inner rear ends of the half nuts, so that when the rod is turned, as seen
in Fig. 28, the half nuts are spread apart and disengaged from the screw c³.
While in this position the upper jaw carrier can be raised and lowered by hand.
A coiled spring surrounding the rod and fast at one end to said rod and at the
other to the piece e is put under tension when the rod is turned to spread the
half nuts and when the jaw carrier has been shifted and the handle 2, released, said
spring returns rod f and the hub re-engages with the hubs of the hooks * to
cause the half nuts to re-engage with the screw c².

page_text: The lower jaw carrier ol is operated for vertical adjustment by a screw whose
lower end provided with a turning collar is stepped into a quick pitched screw (*
passed through and engaging with a foot piece 2 upon the lower forward end of
the portion . An arm n³ is connected to the lower end of the screw 12 and has
upon its under inner side a pin or roller for a purpose to be presently explained.
Journaled respectively in the upper jaw carrier and in the lower jaw carrier and
foot piece m' are the two concentric vertical jaw spindles p² ² each carrying upon
its adjacent ends the detachable jaws between which the work is clamped or
chucked by bringing the upper jaw down upon it and tightening the screw c³..
I will now describe how the monitor head. with. its work carrying chucks is
intermittently rotated, reference being had to Figs. 3, 4, 6, 7, 18, 19, 20 and 22.
Journaled in the post A is a vertical shaft A' extending through a central perfora-
tion in the monitor head and with locking nuts upon its upper threaded end.
Upon the lower end of this shaft is a crank arm B2 with an extension 2, Fig. 7,
projecting through a cut away portion of the post A. A pivoted link v³ connects
the extension u with a lateral: projection on the rear of a horizontal slide bar C'
guided in the supplemental frame bearing 1 (Fig. 3) and in bearing and having
its forward. end connected to a weight D by a cord E' passed over guide pulleys F
journaled on a supplemental frame H. A bell-crank dog I is pivoted to the
outer face of the disk K, Fig. 6, and is so arranged that at each revolution of
the disk and just as the mandrels have been retracted, see dotted lines, Fig. 6, its
outer projecting end comes into contact with a shoulder a³ upon the slide C' and
forces the latter back, thereby turning the shaft A2 and lifting the weight D³. As
soon as the nose of the dog passes or slips over the shoulder a the weight D' draws
the slide C' back again and thereby turns the shaft A back to its former position;
as will be readily understood J' is a stationary trip for throwing the dog I out in
proper engaging position and holding it there and K is a stop-pin against which it
is held while engaging with the shoulder a³. A stationary projection from the
periphery of the disk K' might however be substituted for the pivoted dog I? with
the same results.
Recessed in the collar 6, Figs. 19, 20 and 22 is a pivoted spring projected dog
or pawl which engages with ratchet depressions d', Fig. 18, on the lower inner
side of the monitor head. Just before entering one of these depressions to turn
the monitor head the nose of the dog engages the end of a spring latch e, Fig. 19,
whose nose recessed and guided in the head block C normally engages one of a
series of recesses 9 in the monitor head to hold the same locked, and presses it out,
thereby breaking the lock until the monitor head has been turned by the forward
oscillation of the shaft A² whereupon on the return stroke of the shaft the noseƒ³
enters the next recess to relock the monitor head. As the shaft A' is brought
back by the weight D it is wedged down by a plate h³, Figs. 19 and 22, secured to
the head block C and projecting over an inclined collar upon the shaft thereby
aiding the latch ein securely locking the monitor head.
The means for unlocking, turning, and relocking the chuck spindles will be
understood from the following description, referring to Figs. 4, 21, 31 and 32.
Locked upon the post A just under the head block is a disk L' having detach-
ably secured in recesses in its edge, segment racks of which there are four in the
present instance. These racks lie in the path of travel of pinions one upon each
of the lower ends of the lower chuck spindles so that as the monitor head is being
turned, see Fig. 32, these racks rotate the pinions and with them the chuck spindles
thereby giving the work held by the chuck-jaws a quarter turn.
Just before the pinions come in contact with the racks a pivoted spring latch P,
Figs. 24, 27 and 31, for each chuck is disengaged from a notched collar m³ upon
the lower chuck spindle by a pivoted lever n³ whose inner end is caught by one of
a series of lugs or projections o' on the head block C thereby tripping the lever
and releasing the latch of each chuck. At the same time each of the rollers or
pins o on the levers n' is caught by a cam p³ and caused to enter a depression.q³

page_text: "
in the collar on the disk L which tilts the levers n' and lowers the quick screw (*
thereby loosening the chuck spindles sufficiently to permit of their being freely
turned. Before the chucks come to rest the depression 3 will have returned the
levers and reclamped the chuck jaws.
It will be noticed that there are seven cam depressions and that three alternate
ones are bridged by movable segment pieces. The reason for this is that in
dressing an ordinary valve like Fig. 33 the valve in put into the chuck jaws with
its sent opening pointing into the center of the machine. The chanck occupies the
position shown in Fig. 31. Now as the monitor head turns for the first time to
bring this chuck opposite the line of mandrel 1 (Fig. 31) the intermediate rack
will have turned side of valve out and the cutter of mandrel / will enter and dress
it. In turning however to mandrel 2 which carries a tap it will be observed that the
rack is omitted the cam removed and depression q³ filled up so that the chuck is
merely carried along without turning the work. In passing from mandrel 2 to
mandrel 3 the chuck jaws are again given a quarter turn as before, and side 2 of the
valve is brought out to be acted on by the cutter and tap mandrel 3 and 4 respec-
tively. Again in passing from mandrel 4 to mandrel 5 the chuck jaws are given a
quarter turn to bring out side 3 of the valve which is acted on by the cutter and
tap of mandrels 5 and 6 respectively. Finally in passing from mandrel 6 to the
starting point the jaws are again turned throwing side 2 of the valve inward. The
attendant here removes the dressed valve and places in another to be dressed.
While I have thus followed up the action of one chuck it is of course understood
that six pieces of work in six chucks are being simultaneously dressed, while the
seventh chuck is delivering its finished work and receiving a fresh piece.
Of course it is to be understood that the mandrels can carry dies as well as taps
and reamers; and, while I have shown the oscillating shaft connected to the
monitor head by ratchet and pawl connection, any other equivalent connection may
be substituted.
'
While any suitable means for securing the taps to their mandrels may be
employed I prefer to use the devices of Figs. 8, 9 and 10 where the head of the
mandrel is recessed to receive a spring buffer against which the end of the tap
rests. Secured to the tap is a yoke piece from which rods a extend back and
are connected to a sliding collar embraced by the fork of the arm j. From
this it will be seen that the tap is held projected by the buffer until it has entered
the work and connected to cut its thread. If the pitch of the tap is such that it
enters the work faster than the advance of the mandrel it simply draws forward its
socket and at the proper time through the medium of the arm releases the latch
and reverses the direction of revolution of the mandrel.
Having now particularly described and ascertained the nature of my said
invention and the manner in which the same is to be performed, I declare that
what I claim is :-
