A (Fig. 3) represents the timbers or foundation to which the supporting frame B,
of this improved machine is secured.
C (see Fig. 1) represents the driving shaft that is arranged lengthwise of the
machine and has bearing in suitable boxes C¹, rigid with the supporting frame.
Said shaft, at one end, (in the present instance the right hand end of the machine)
is provided with the driving-pulley C, and is suitably intergeared, as at D,
with a cam shaft E, that extends lengthwise of the machine parallel with the
driving shaft and has suitable bearing in boxes, e, rigid with the supporting
frame.
Upon shaft E, in the present instance (near the central portion of the same, is
operatively mounted a cam E. that is adapted to engage a roller f', on a lever f,

page_text: that is fulcrumed, as at f³, to the rear portion of the top of the supporting frame.
Lever extends forwardly, and, at its forward or free end is operatively
connected, by means of a rod or link f' with an arm or lever operatively
mounted on a shaft fo that extends transversely of the machine and has bearing
in suitable boxes f rigid with the foundation timbers of the supporting-frame
below.
The connection of lever with connecting, rod or link is preferably by means
of a stud, pin or bolt f loosely embraced by the free end of said lever, in
conjunction with a pin or bolt that pivotally secures the upper end of said link
to stud or pivot f' (see Fig. 4). The connection of link f³ with lever f therefore
constitutes a sort of universal joint.
Shaft at its forward end is provided with a lever, f that, at its upper end,
is operatively connected, by means of a connecting rod fo with the chain-link-
blank carriage, Lc, that is adapted to reciprocate lengthwise of the machine,
being mounted upon a suitable track G G, provided for the purpose (see Figs. 1, 2
and 3) said carriage being adapted to convey the open ended heated link from the
heating furnace to, and insert the same into, the last link added to the chain being
made, leaving the newly added unwelded link in position in the last welded link
of the chain, and to be operated upon by squeezing bars to bring the free ends of
the heated link together for the subsequent welding operation, all as will
hereinafter fully appear. The cam-actuated mechanism hereinbefore described,
operatively connected with the link carriage, is adapted to actuate said carriage
in the direction toward the heating furnace, in which the open-ended link-blanks
are heated, for receiving a heated link from said furnace, and other means or
mechanism are preferably provided for actuating said carriage in the direction
away from the heating furnace.
The means just referred to, for actuating the link carriage in the direction away
from the heating furnace, comprises preferably one or more springs acting
oppositely to the direction in which said carriage actuating mechanism is actuated
by the aforesaid cam E'. I prefer two springs for the purpose, one f¹ (see Fig. 3)
attached at its upper end to lever fand at its lower or opposite end to a spring
bar SB, below, and another spring attached at one end to lever f° and at its
other end to any rigid support, such for instance as one of the foundation timbers
of the supporting frame of the machine.
Track GG comprises preferably a pair of rods or bars, arranged parallel with
each other and in the same horizontal plane, being rigidly supported in any
suitable manner, preferably by one or more brackets or arms g (Fig. 1) projecting
forwardly of and rigid with the supporting-frame and being also preferably
rigidly secured, as at g' (Figs. 2 and 3) to the casing of the heating furnace wherein
the chain-link-blanks are heated.
The construction of the link carriage is preferably as shown in Figs. 7, 8 and 9,
wherein the same comprises three sleeves H, H aud H¹ rigid with one another,
sleeves H H nicely but easily embracing the inner rod or bar of the link carriage
track and sleeve H' nicely but easily embracing the outer rod or bar of the track
and the link carriage also comprises a sleeve h that extends lengthwise of the
carriage and has a cylindrical bore h¹ wherein is rotatably supported the
correspondingly shaped shank I of the link holding tongs, said shank being held
from moving end wise of the supporting sleeve or bearing by means of a
shoulder I'formed on the shank at the forward or outer end of the supporting-
sleeve, and a collar 1' rigidly mounted on the shank at the inner or rear end of the
supporting sleeve or bearing.
Shank I, forward of the supporting sleeve, is preferably square in cross section,
and at its forward end is bifurcated or forked, as at I, for the reception of a pair
of jaws I* of the tongs that are adapted to receive and hold the link and insert the
same into the link last added to the chain, said jaws being preferably spring jaws
and arranged in the same vertical plane, and said jaws are preferably composed of
a single piece secured, at the rear or inner end, to the shank of the tongs by means

page_text: of a pin or bolt I. Jaws I, on their opposing faces near their forward extremity,
are recessed or grooved transversely, as at I, Fig. 7, said recesses being located
directly opposite to each other and adapted to receive the closed or upper end of
the open-ended heated chain link upon the delivery of the link, from the heating
furnace to said jaws, the link hanging from the recess or groove of the lower
jaw of the tongs when the tongs jaws are open and being firmly held within the
recesses of both jaws when the latter are closed, the heated link being delivered
to the tongs sidewise with its open end lowermost and the jaws of the tongs of
course being open when receiving the link. To prevent the link from being shoved
or displaced rearwardly of or by the recesses or grooves in the jaws, a stop I', is
provided just rearward of said grooves or recesses, said stop comprising preferably
a pin rigidly secured to the one jaw and extending far enough into or through the
other jaw to prevent the displacement of the free end of said pin from the respective
jaw when the jaws are opened (see Fig. 8).
Referring now to the heating furnace in the heating chamber of which the open-
ended link blades are heated and from which the heated link is, by the mechanism
hereinafter described, delivered to the jaws of the tongs of the link carriage.
J (see Figs. 2 and 3) represents the casing of the same, said casing being mounted
preferably upon legs J¹, and J' represents the combustion and heating chamber that
is located, preferably centrally of and extends lengthwise of the furnace. Said
combustion and heating chamber is open at the top, as at J, and at one side of said
opening, preferably about midway between said opening and the one side of the
furnace, namely that side of the furnace opposite to the path of the aforesaid link
carriage, is located an endless travelling belt or conveyor K that passes over and
under the furnace over wheels K' at the ends of the furnace. Said endless
travelling belt or conveyor comprises preferably an endless metallic chain, each
link whereof has an inwardly projecting sprocket or projection that is adapted to
engage corresponding holes in the peripheries of wheels K. Wheels K' are
operatively mounted on shafts K, that are journalled in suitable boxes K', supported
by brackets secured to the adjacent end of the furnace casing.
represents the holders or carriers from which the articles to be heated
are suspended. Said holders or carriers are secured, preferably removably, to
the endless travelling belt or conveyor in any suitable manner, but equidistant
apart. Holder or carriers at the inner side of the endless conveyor, are bent
toward the heating chamber of the furnace, as at k³, and said bent members of the
holders, at their free ends, terminate in hooks upon which the chain link
blanks L are hung, the parts being so arranged that in operation the chain link
blanks to be heated shall be carried into or through the heating chamber of the
furnace. The one shaft K' is provided with a ratchet wheel K₁ (see Fig. 2) that
is adapted to be engaged and actuated by a pawl e', suitably secured to the pin e
of a crank wheel or crank E' operatively mounted on cam shaft E. The arrange-
ment of parts is such that once in a rotation of crank wheel or crank E³, pawl e
will actuate ratchet wheel K' to propel endless conveyor K the distance required
to bring a heated blank in proper position for delivery to tongs-jaws I*.
The mechanism for effecting the delivery of the heated link-blanks, from holders
or carriers to tongs-jaws 1, is also actuated by means operatively connected with
cam shaft E and is preferably as follows:
:-
E represents a cam wheel operatively mounted on cam shaft E. Cam wheel E'
is provided with a peripheral groove e engaged by a roller secured to reciprocating
bar L that extends transversely of the heating furnace below conveyor K and has
bearing, at opposite ends, in suitable boxes or sleeves L' rigid with the furnace
casing. Reciprocating bar L, at its outer end, is operatively connected, by means
of a lever L' with a reciprocating rod or bar L³ that extends parallel with bar L
and has bearing in boxes or sleeves L rigid with the furnace casing. Reciprocating
rod or bar L, also extends in under conveyor K and at its free end terminates in
an upright member L', slotted, as at L' (see also Fig. 10) to straddle blank holders
or carriers and adapted to engage the adjacent side of the heated link and shove

page_text: or force the same off the respective holder or carrier 2 onto the lower jaw of the
tongs of link carriage Lc, the arrangement of parts being such that cam wheel E
will actuate said mechanism to cause the latter to engage the heated links on the
holders or carriers at the proper time to cause them to be delivered to said tongs,
and the parts are preferably so timed that just as the holder or carrier * shall have
brought a link into position for delivery to the tongs of link carriage Lc, the means
for effecting said delivery shall have been actuated simultaneously to perform its
function and the link carriage shall have been simultaneously brought into position
to receive the link.
The top of the furnace casing is recessed or offset downwardly, as at J*, to
accommodate the location and operation of the tongs of the link-carriage.
As already indicated, the tongs of the link carriage, when receiving a link from
the heating furnace, is open, and the link hangs from the lower jaw of the tongs
with the open end thereof presenting downwardly. Suitable means are provided
for holding the tongs open preparatory to the reception of the link. The means
employed comprises preferably a can or eccentric M (see Fig. 8) interposed
between jaws 14, rearward of stop 17, and integral with or operatively mounted
upon a turnable pin or bolt m that has bearing in the members of the forked end of
the shank of the tongs, pin or bolt m being provided at one end with a cross-
shaped head or star wheel m¹ adapted to be actuated by mechanism operatively
connected with the cam shaft E, to cause cam or eccentric M to be actuated to close
the jaws of the tongs. Cam or eccentric M is preferably of the form or construction
shown in Fig. 8, wherein the same has flat portions M' diametrically opposite its
axis, and is convex, as at M³, between the flat surfaces, the convex portion of
course having the greatest diameter, and hence by turning said cam or eccentric
into the position shown in solid lines in Fig. 8, to bring the flat sides thereof in
engagement with the jaws of the tongs, the latter, by means of a spring acting in
the direction to close the jaws (preferably by virtue of the spring in the metal
of which the jaws are composed) are closed, and by turning said cam or eccentric
so as to bring the convex sides or that portion of the same having the greatest
diameter in engagement with the tongs-jaws, the latter will be opened.
The open ended link to be inserted into the welded link last added to the
chain of course has to be brought into the proper position for insertion into
the link last added to the chain, preparatory to such insertion, and the link last
added to the chain should be properly held for receiving the open-ended unwelded
. link.
In Figs. 11 and 12 is shown the position that the link last added to the
chain assumes preparatory to the reception of the new link, and it will be
observed that the link last added to the chain, as shown in said figures, lies
in a plane oblique to a vertical plane with the sides of the link presenting in the
path of the link to be next added and welded. The means employed for actuating
the chain to bring the last link added to the chain into the position shown in
Figs. 11 and 12 will be hereinafter described. Suffice it here to remark that said
means is actuated at the proper time to bring said link into the position indicated
at the proper time to receive the new link.
It follows, therefore, that in order to bring the open ended link into the proper
position shown, relative to the position of the link last added to the chain, and
shown in Figs. 11 and 12, from the hanging position it occupies when received by
the open jaws of the tongs of the link carriage, the open ended link must first
be actuated to assume a horizontal position with the open end thereof presenting
outwardly and then must be given a partial turn laterally and it also follows that
suitable means must be provided for closing the jaws of the tonga preparatory to
actuating the link into a horizontal position so that when the link assumes such
horizontal position it will retain said position until thereupon turned laterally, and
that suitable means should be provided whereby the open-ended link shall be held
in such laterally turned position until the same has properly been inserted in the
link last added to the chain.
..

page_text: Suitable means for actuating cross or star wheel m¹, to thereby actuate cam or
eccentric M to close the jaws of the tongs of the link carriage, is shown in Figs. 2
and 3, wherein N represents an oscillating shaft that is arranged transversely of
the machine and has bearing in suitable boxes n supported, for instance by a
standard n', rigidly secured to the casing of the heating furnace. Shaft N, is
provided with a lever N¹ that has a roller N' engaging cam grooves e of a cam
wheel E operatively mounted on cam shaft E. At its forward end, shaft N is
provided with a lever N³.
The trend of groove e of cam wheel E is such that lever N', shaft N and
lever Nare actuated in the direction of the arrow (see Fig. 2) and the arrange-
ment of parts is such that when link carriage Lc is in position receiving a link,
lever N will engage the left hand side of the upwardly projecting wing or member
of the cross shaped or star wheel m¹ so that when said lever is actuated in the
direction indicated, wheel m' will thereby be actuated to give cam or eccentric M
a quarter turn to permit the jaws of the tongs of the link carriage to close, the
trend of the groove of the cam-wheel and the length of lever N' being such as to
cause the free end of such lever to be moved a distance sufficient to permit the
cross shaped or star wheel m¹ to pass thereunder, after being turned, in the
reciprocation of the link-carriage, from and to the heating furnace.
The jaws of the tongs of the link carriage having closed upon the link, the latter
is firmly held, and it follows that when the link is thereupon actuated, to assume
a horizontal position with its open end presenting outwardly, the link will be held
in such horizontal position.
The means employed for actuating the link to assume the horizontal position
indicated, comprises preferably an angle plate or iron, O, the upright meinber O¹
whereof is adapted to be engaged by the link hanging from the tongs of the link
carriage when said carriage is reciprocated in the direction away from the heating.
surface (see Figs. 2, 3 and 13).
.
Angle plate O is secured preferably to the top of the furnace casing, at the
outer end of the downward offset J' in the top of said casing, and, when engaged
by the link, causes the free or open end of the latter to be lifted or swung
outwardly into a horizontal or approximately a horizontal plane with the end of
the link held between the jaws of the tongs of the link carriage, as shown in
Fig. 14.
The shank of the tongs of the link carriage, at or near its rear or outer end,
is provided with a laterally projecting lug or member I" that is adapted to engage
a stationary cam or incline 1 rigid with the supporting frame of the machine (see
Figs. 1 and 3).
The link carriage is adapted to travel, in the direction away from the heating
furnace, beyond the point at which the open ended link is connected with the
chain. The trend of cam or incline P is such that when said cam or incline is
engaged by lug or member 18 of the shank of the link holding tongs during the
reciprocation of the link carriage away from the heating furnace, the link holding
tongs and consequently the link held thereby, will be given a partial turn laterally
to bring the open end of the link in proper position for the insertion of said link
into the link last added to the chain, the trend of said cam or incline in the present
instance being forwardly into the direction away from the heating furnace and
hence the link holding tongs is given a partial turn forwardly, thereby causing
the link to assume the position shown in Figs. 11 and 12 in which position the
open end of the link can with facility be inserted into the link last added to
the chain, as illustrated in said figures, the means for holding the chain, that
will hereinafter be described, being of course swung outwardly or forwardly
into the path of the link carriage to bring the link last added to the chain
into proper position for the reception of the new link. The location of cam or
incline relative to the point at which the link is connected with the chain
is such that the link holding tongs and the link held thereby shall have been

page_text: given the proper turn laterally when the link, during the reciprocation of the
link carriage away from the heating furnace, shall have reached the point at
which the open ended link is inserted into the link last added to the chain and
said cam or incline is preferably formed upon a stationary plate P¹ the front
surface whereof extends straight outwardly from the forward extremity of the cam
or incline parallel with the path of the link carriage so that when the link carriage
has travelled beyond or past the point at which the open ended link is connected
with the chain to permit the chain holding means to be swung outwardly or
forwardly to bring the link last added to the chain in position for the reception of
the new or open link, the link holding tongs and link held thereby shall be
retained in the laterally turned position until after the new open link has been
properly inserted in the link last added to the chain.
Suitable means are provided for actuating cross shaped or star wheel m¹ to turn
cam or eccentric M in the direction to open the jaws of the tongs of the link
carriage immediately upon the proper insertion of the open-ended link into the link
last added to the chain. Preferable means for this purpose is shown in Figs. 1
and 3 wherein Q represents an oscillating shaft that is arranged transversely of
the machine at a suitable elevation and is supported by a standard Q¹ rigid with
the supporting frame.
Said oscillating shaft at its rear end is provided with a downwardly extending
arm or lever Q that at its free extremity is provided with a roller Q adapted to
be engaged by a cam E' operatively mounted on cam shaft E. At its opposite or
forward end shaft Q is provided with an arm or lever Q.that is adapted to engage
the forward side of the upwardly projecting wing or member of cross-shaped or
star wheel m¹ and actuate said wheel to turn cam or eccentric M to open the jaws
of the link holding tongs. About midway of its length lever Q³ is jointed, as
at Qin such a manner that the lower member of said lever is free to move
independently of the other or upper member of said lever in the direction toward
the heating furnace, but is prevented from independent movement in the opposite
direction by a suitable stop Q7 (see Fig. 3) formed or provided at the joint of the
lever. The oscillation of shaft Q is in the direction away from the heating
furnace, and the parts are so arranged and timed that when the open-ended link
has been properly inserted into the link last added to the chain cam E' shall have
come into position to actuate lever Q and thereupon actuate said lever, shaft Q
and lever to cause the latter to give cross shaped or star wheel m¹ a quarter
turn and thereby actuate cam or eccentric M to open the jaws of the link holding
tongs, permitting the free or open end of the open link to drop or fall by gravity
as shown in dotted lines, Fig. 12.
As herein before indicated, the reciprocation of the link-carriage away from the
heating furnace is effected by means of springs "," and the reciprocation of
said carriage in the opposite direction is effected by means of the lever mechanism
operatively connected with said carriage and actuated by cam E'.
The construction of said cam E' is such, however, that said cam will remain idle
for a short time after the connection of the link with the chain to permit
springs f, f to cause the link carriage to recede and thereby entirely release
the link from the link holding tongs, if such release has not already been effected,
leaving the link hanging from the last welded link of the chain.
The parts are of course so arranged and timed that the jaws of the link holding
tongs shall be opened immediately after the proper insertion of the open link into
the link last added to the chain, whereupon the link carriage, by means of
springs and the peculiar construction of cam E' permitting the action of
said springs, shall be actuated to release the link or cause the latter to be dis-
engaged from the link holding tongs, whereupon the means for holding the chain
with which the open link has just been connected, is, by means hereinafter
described, swung back to its normal position out of the way of the path of the link
carriage, permitting the latter to return to the heating furnace for another link,

page_text: cam E' being of such construction as already indicated, as to effect the return of
said carriage to the heating furnace. The construction of cam E' is clearly shown
in Fig. 15.
.Suitable means, preferably a perforated pipe R, as shown in Figs. 1 and 3, is
provided for conducting and discharging water upon the link holding tongs
preparatory to its return to the heating furnace for another link, said pipe being
located preferably at a suitable elevation between the point at which the links are
added to the chain and the heating furnace, suitable means (not shown) being
provided for causing the discharge of water at the point indicated to be inter-
mittent, that is, for causing the pipe to discharge water upon the tongs only at the
time of its return to the heating furnace for another link.
I would here remark that the partial turn of the link-holding tongs by cam or
incline P is against the action of a spring 1°, secured, for instance, to supporting
sleeve or bearing hand, at its free end, bearing against the one side of the square
portion of the shank of the link holding tongs; hence, as lug or member I rides
a down cam or incline P in the reciprocation of the link carriage toward the heating
furnace, the tongs, by the action of said spring, will be returned to its normal
position.
Referring next to the means employed for holding the chain during the insertion
of an open link into the link last added to the chain, and for holding the open
ended link after its connection with the chain for the subsequent squeezing and
welding operations hereinafter described, and for guiding and conveying the chain
from the machine, 7 (see Figs. 3, 6, 7, 16 and 17) represents an upright hollow
turnable barrel or cylinder that extends upwardly through a sleeve that, at its
upper end, is pivotally hung, as at r³, from and between forwardly projecting
arms a¹ of upright housings a, that are bolted, as at a³, to the supporting frame of
the machine, barrel or cylinder r being supported within sleeve by means of a
collar, rigidly mounted in any suitable manner upon the upper end of said barrel
or cylinder, said collar at its lower end being provided with a pinion for a
purpose hereinafter made apparent, said pinion being rigid or integral with said
collar and resting upon the top of sleeve . It will thus be observed that barrel
or cylinder r is adequately supported and at the same time is free to turn within
the supporting sleeve . The bore of barrel or cylinder is just large enough to
freely accommodate the passage of the finished chain up through the same, whence
the chain passes to and over sheaves (Fig. 7) that are secured to any suitable
support overhead and thence the chain passes downwardly to the floor of the shop
where it accumulates as rapidly as manufactured.
Barrel or cylinder is located at the rear of the path of the link carriage, and,
at its lower end, is provided with suitable means for holding the chain, said chain
holding means comprising preferably four spring bars or jaws r arranged in the
form of a square in cross section or bottom plan, as shown in Fig. 17. Chain
holding bars or jaws are located a suitable interval apart to receive and accom-
modate the passage of the chain up through barrel or cylinder r, said bars or jaws
being adapted, by virtue of their spring, to take a positive hold of the chain. The
construction and arrangement of holding bars or jaws of the chain holding device
is preferably such that the chain holding device is adapted to take hold of but one
or two links of the chain at a time for instance, the link of the chain last welded,
from which link, as already indicated, hangs the open-ended link that has last been
connected with the chain ready for the squeezing operation, that is, ready for the
operation that shall bring or lap the free ends of the link together in position for
the subsequent welding operation. Preparatory to the welding operation, however,
the chain, by means. hereinafter described, is lifted the length of a link to thereby
bring the link, whose ends have just been lapped together, within the clutching
portion of the chain-holding-device, thereby causing said link to be firmly held
during the subsequent welding operation.
By means of the feature just described whereby the link-holding device is
adapted to clutch but one or two links of the chain, it follows that the elevation

page_text: of the chain, by means already alluded to and hereinafter described, is facilitated,
and said feature is attained by the construction shown in the figures already
referred to, wherein the clutching bars or jaws of the chain holding device,
from the point at which they are adapted to clutch the chain, diverge outwardly
and upwardly.
Bars or jaws are preferably secured to barrel or cylinder by means of a
clamp, that is recessed at its inner periphery as at for the reception of said
jaws or bars, and, in open relation with said recesses, is provided with lateral screw
threaded perforations for the reception of screws that screw into correspondingly
threaded holes in the jaws of the link holding device, thereby securing said jaws or
bars to the clamp.
Barrel or cylinder being located at the rear of the path of the link carriage, as
already indicated, it follows that said barrel or cylinder and attached chain
holding device must be swung outwardly or forwardly at the proper time for
bringing the last welded link of the chain in position for the reception of the link
carried by the link carriage.
Preferable mechanism for thus swinging barrel or cylinder outwardly is shown
in Figs. 1 and 16, and is adapted to be actuated by a cam E' operatively mounted
on cam shaft E. The mechanism shown comprises an arm or lever S, operatively
mounted upon a short shaft S₁ that is arranged parallel with the cam-shaft between
the latter and barrel or cylinder and has bearing in rearwardly projecting luge or
ears a of housings a. Lever S is provided with a roller S'engaged by cam E.
Shaft S', adjacent arm or lever S, has operatively mounted thereon an upwardly
extending arm or lever, S', to which. barrel or cylinder is operatively connected
by means of a link S. Portion es of cam E' is adapted to actuate the mechanism
just described to swing barrel or cylinder r outwardly into the path of the link
carriage, and S represents a spring that is attached at opposite ends to lever S and
a spring bar S6 (Fig. 7) respectively, and acts in the direction to actuate said
mechanism to swing barrel or cylinder r rearwardly or inwardly out of the way of
the path of the link carriage.
The open-ended link is clearly shown in Figures from 11 to 14 inclusive, upon
reference to which drawings it will be observed that the free ends of the link are
separated a suitable distance so that the link is easily inserted into the last welded
link of the chain as herein before described, and the free ends of the link are cut
diagonally in such a manner that when said ends are brought together by the
squeezing bars, that will presently be described, said ends will lap the one over
the other, whereupon said ends of the link are ready to be welded together. T (see
Figs. 1, 3 and 7) represents the bars, squeezing bars, as I term them, for bringing
the face ends of the link together as just described.
Two of said bars are provided, one for each extremity of the open link, said
bars being located, respectively, at opposite sides of the link and adapted to
simultaneously act upon the link. The location of said squeezing bars is preferably
in a plane just forward of the point at which the links are welded and rearward
of the path of the link carriage, and the bars, by mechanism that will presently
be described are adapted to be reciprocated end wise of suitable bearings at that
are rigid with the supporting frame of the machine. The squeezing bars are
recessed or grooved vertically on their faces to nicely fit and embrace the round
surface of the link, said grooves or recesses being preferably of such size that
said bars will close together as shown in Fig. 18, when the extremities of the link
shall have been properly lapped together. The squeezing bars are actuated in
.the direction to lap the extremities of the link together by means of swinging
levers T', that are fulcrumed, as at T', to the supporting frame, being operatively
connected at their forward end, with the respective squeezing bars in any suitable
manner and being actuated, to reciprocate the squeezing bars to cause the latter
to perform their function, by cams E7 operatively mounted on cam-shaft E,
levers T being provided with rollers T at the point of engagement by the
actuating cams, and the squeezing bars are separated or returned to their normal

page_text: position by means of springs T that are attached at opposite ends to the squeezing
bars and supporting frame of the machine, respectively, as shown very clearly in
Fig. 3. As already indicated, the squeezing bars are located at the rear of the
path of the link carriage, and the parts are so arranged and timed that barrel or
cylinder r and attached chain holding device shall be swung inwardly or rearwardly
into a position directly between the squeezing bars immediately after the insertion
of the open ended link into the link last added to the chain, whereupon the.
mechanism for actuating the squeezing bars, to cause the latter to squeeze and
properly lap the free extremities of the link together, performs its function.
Barrel or cylinder r and attached chain holding device is swung into the position
between the squeezing bars, as already indicated, by means of spring S', the
inward or rearward movement of said barrel or cylinder being partially limited by
portion e' of cam E, which portion being of less radius than portion of the cam
permits spring S to act to swing barrel or cylinder r and attachments inwardly
during the passage of roller S' of lever S from portion to portion e' of cam E³,
the radius of portion e' of the cam being such that said barrel or cylinder shall be
swung into position directly between the squeezing bars as above indicated, portion e
of the cam being adapted to hold cylinder or barrel r and attached chain holding
devcse in position between the squeezing bars until the latter have properly
performed their function.
The free extremities of the link having been lapped together, as just hereinbefore
described, the link is in condition for the welding operation. The link, hanging
loosely however, from the link last welded, that is, not being rigidly held, it is not
yet' in proper position for the welding operation, but the link, whose extremities.
have just been lapped together, or rather the portion of the chain with which said
link is connected, should be lifted or elevated to bring the upper end of the link to
be welded within the chain holding device, to be firmly held or clutched by bars or
jaws of the chain holding device. The mechanism employed for thus elevating
the link to be welded consists preferably of a bar t (see Fig. 19) operatively
connected with an arm or lever ', of an oscillating shaft t that has bearing in
box rigid with the supporting frame, said shaft also having an arm or lever t*
that is provided with a roller to engaged by cam E operatively mounted on the
driving shaft.
Near its forward end, bar t is operatively connected, by means of a
link with a tilting lifting lever that is fulcrumed near its central portion,
being preferably loosely mounted upon shaft S¹.
Lever is provided with a roller t that is engaged by a cam E operatively
mounted on cam shaft E. The parts are so arranged and timed that bar tis
by means of the mechanism operatively connected with said bar and actuated by
cam Es, actuated forwardly or outwardly and inserted into the adjacent link of the
chain and immediately upon the insertion of bar t into said link of the chain cam E*
will have assumed a position to actuate lifting lever ', resulting in the upward
actuation of the forward or outer end of bar t to elevate or lift the link into which
said bar has been inserted and thereby lift the link into position to be held by the
chain holding device. The arrangement of parts is preferably such that bar t
shall be inserted into the third last link of the chain (inclusive of the link to be
welded). At least the arrangement of parts should be such that the links of the
chain, above the link into which the bar t is inserted, are rigidly held by the chain
holding device, and the link into which the bar is inserted is preferably one that
is not rigidly held by the chain holding device, the object being that when the link,
into which lifting bar t is inserted, and the links below said link, are elevated by
means of said bar, the chain will be automatically fed from barrel or cylinder r by
means of the gravity of that portion of the chain that leads downwardly to the
floor of the shop at the rear of the machine, and I would here remark that a piece
of chain previously made is used to furnish the weight when the machine is first put
in operation.
The portion of the chain including the link to be welded, having been elevated as
hereinbefore described, the mechanism for actuating bart is returned to its normal
B

page_text: position by means of springs t° and 10, both of said springs at their lower end being
attached to any suitable support, such as the spring bars below, and at their upper
end being attached to levers and t' respectively. Said springs not only return
the lever mechanism operatively connected with bar and actuated by cams E*, E'
to its normal position, when the actuating levers of said mechanism are released
by said cams, but also prevent any loss of motion during the operation of the
parts.
U (see Figs. 7 and 20) represents the anvil upon which the link is welded, and
V represents the hammer for performing the welding operation. The head U! of
the anvil, upon its face, is provided with the female-die U, that has a recess U³ for
receiving the end of the link to be welded. The location of said anvil is such,
relative to the chain holding device, that when the latter is swung inwardly or
rearwardly to a perpendicular position, after the link to be welded has been
elevated, as herein before described, the link to be welded will enter recess U'in the
face of die U in position to be operated upon by hammer V. Barrel or cylinder.r
and attached chain-holding-device is swung inwardly, to bring the link to be
welded within the recess of the die of the anvil by means of the depression e8 in the
periphery of cam E, said depression permitting spring S¹ to actuate the mechanism
operatively connected with the supporting sleeve of said chain or barrel to swing
the latter to the position indicated and thereby bring the link in position for the
first blow of the hammer, and the arrangement of parts are so arranged and timed
that the chain holding device shall be swung inwardly to bring the link to be
welded in position for welding immediately upon the elevation of said link, as
hereinbefore described. Hammer V, upon its face, is provided with the male die V',
that has a lug or projection V adapted to engage the inner side of the lower end of
the link, or that end that is to be welded. The shape of said projection or lug and
the form and size of the recess in the die of the anvil being such that the welded
end of the link shall be given the proper rounded form and finish during the
welding operation.
The construction of hammer D and the mechanism employed for operating the same
is clearly shown in Figs. 1, 3, 5, 6, 7 and 22 wherein V represents the hammer arms"
to and between the lower ends whereof the hammer is suitably secured, the
hammer arms extending upwardly and rearwardly at the outside of the respective
housings a to which the arms are pivotally secured, as at V. The hammer-arms
extend a suitable distance above their pivotal bearings, and at their upper end are
preferably braced and tied together by means of a cross rod or cross bar V³, that
is operatively connected, by means of a link V with an upwardly extending arm or
lever V of an oscillating shaft V that has suitable bearing in a box V' (see
Fig. 22) rigid with the supporting frame, said shaft having also an arm or lever V,
that, at its free or outer end, is provided with a roller V adapted to engage radial
slots, recesses or pockets elo of a cam E10, operatively mounted on cam-shaft E, that
is adapted to actuate lever V and the hammer operatively connected therewith
to elevate or swing the hammer outwardly from the anvil. The construction of
said cam, that is properly termed the hammer cam, is very clearly shown in Figs. 7
and 22 and is such that the hammer shall be elevated or swung outwardly far
enough to accommodate to operation of the link carriage, squeezing bars and
swinging movements of the chain-holding device.
The hammer is actuated to deliver its blows partly by gravity, but more
especially by means of springs V" connected at one end with the hammer arms,
and at their other end with a spring bar S b. The hammer is adapted to deliver
as many blows as there are slots or pockets 10 in cam E10, the hammer, by means
of the hammer cam illustrated, being adapted to deliver four consecutive blows, the
hammer-cam being provided with four of said recesses or slots arranged at suitable
intervals. By the construction of hammer-cam shown, it will be observed that, in
the operation of the machine, as roller V" of lever V10 falls into said recesses or
slots of the hammer cam, lever V10 and the mechanism operatively connecting it
with the hammer will be actuated to permit springs V₁ to co-operate with gravity

page_text: in actuating the hammer to cause the latter to deliver a blow, said springs being
strained or put under tension when the cam actuated mechanism is operated to
elevate the hammer.
The parts are so arranged and timed that the hammer shall be actuated to deliver
its first blow immediately upon the reception, by the die of the anvil, of the link to
be welded. It is manifest however that in order to properly weld the link, blows
should be delivered, alternately, upon opposite sides of the link, and hence, suitable
means or mechanism should be provided for giving the chain holding device and
link to be welded a half turn in the interval between successive blows of the
hammer. The mechanism employed for giving the chain holding device and
consequently the link being welded a half turn, as just indicated, is preferably as
follows: As herein before described, cylinder or barrel r that supports the chain
holding device, is rotatably supported, and is provided with a pinion Said
pinion is in mesh with a rack W, that is held from displacement from the pinion by
means of over-hanging lips or projections a of housing a, and is operatively
connected, by means of a link W' with an upright lever W₁ that is fulcrumed at its
lower end, as at W³ (see Fig. 6) and is provided with a roller W (see also Fig. 1)
adapted to be engaged by cam groove e¹¹ in the periphery of cam wheel E" that is
operatively mounted on cam-shaft E, the trend of said groove being such and the
parts being so arranged and timed that said lever shall be actuated between
successive blows of the hammer and reciprocate rack W the distance required to
give pinion a half rotation and thereby give the chain holding device and link to
be welded the half turn required to bring the opposite side of the link being welded
in position to receive the next succeeding blow of the hammer, the hammer
operating mechanism and chain holding device turning mechanism being so timed,
relative to each other, that the link being welded will be given a half turn in the
interval of time between successive blows of the hammer. It will be observed
however that when the last blow of the hammer has been delivered the link that
has just been welded is not in proper position to receive the next incoming open
ended link, but that a quarter turn must be given to the welded link to bring the
same into the position required for the reception of the next incoming open-ended
beated link. The means preferably employed for giving the chain holding device,
and consequently the last welded link, the quarter turn just indicated, is as
follows:-
X (see Fig. 6) represents a shaft that is arranged parallel with the cam-shaft E a
suitable distance below the latter and supported by the supporting frame. Shaft X
is intergeared, as at X' (see also Fig. 1) with the cam shaft in such a manner that
the speed of shaft X will be one-half that of the cam shaft. Upon shaft X is
operatively mounted a cam-wheel X that is provided with a peripheral cam-
groove X, engaged by roller X suitably secured to a sliding plate or block X*
that is adapted to reciprocate end wise of suitable ways or guides X formed on or
rigid with the supporting frame, as shown very clearly in Fig. 6, and lever W¹
is fulcrumed to said sliding plate or block, the trend of the groove in cam-
wheel X being such, and the parts being so arranged and timed that said lever
shall, at the proper time, after the delivery of the last blow of the hammer and
before another open ended link is brought into position for connection with the
chain, be actuated by means of its operative connection with cam-wheel X² to
reciprocate rack W the required distance to give pinion a quarter of a rotation
and thereby give the chain holding device a quarter turn, bringing the link last
welded in the position required for the reception of the next succeeding link.
It will also be observed that the chain holding device must be swung outwardly
to bring the welded link, or link being welded, out of the recess of the die of the
anvil in order to permit the turning of the link as hereinbefore described. The
chain holding device is thus swung outwardly by means of projections or elevations
between depressions in the periphery of cam E³, actuating lever S of the
mechanism for swinging the chain holding device outwardly, said projections of
cam Eª being located the required interval apart to cause the chain holding

page_text: device to be swung outwardly at the proper time, that is, just before the link is
turned.
Some of the cams on cam shaft E may, of course, be integral with each other.
Another important feature to which I would call attention, consists in the manner
of supporting the anvil whereby the machine does not receive the shock of the
hammer blows, but the shock, instead, is transmitted to the foundation timbers of
the machine.
The construction is very clearly shown in Figs. 7 and 20, wherein Y represents
an iron bar or brace to the upper end of which the rear end of the anvil is bolted
as at Y. At its lower end brace Y is secured to one of the foundation timbers,
preferably by means of a wedge or key Y. Brace Y, at its upper end, is
preferably cut away, as at Y forming a seat for the rear end of the anvil. The
frame work of the machine is, of course, suitably slotted to accommodate the
location of the anvil. The head of the anvil does not, however, abut the supporting
frame, but sufficient clearance Z is provided between the anvil head and supporting
frame that when the hammer delivers its blows the shock therefrom shall not be
transmitted to the supporting frame but shall be transmitted to brace Y and thence
to the foundation timbers.
