WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake, and Co, Patent Agents,
Southampton Buildings, London, "IMPROVEMENTS IN MACHINERY FOR TURNING
BAGS OR SACKS AFTER STITCHING, AND FOR PRESSING AND STACKING THE SAME
[a communication to him from abroad by Samuel T Lockwood of Chicago, Illinois

"
This invention relates to machinery for turning or reversing bags or sacks after
the seams have been sewn in the manufacture thereof, the object of the said
turning or reversing being to cause the seams to be inside instead of outside. The
said machinery also presses the said bags or sacks and places them in piles when
they have been turned.
.
In carrying the said invention into practice I provide a travelling or recipro-
cating frame or carriage bag turning or reversing arms, a transverse rod supported
in, and carried by, the carriage, and plates mounted on the rod and attached
adjustably thereto by means of set screws. There are segmental slots in the
forward parts of the plates. The arms are pivotted at their rear ends to the rear
parts of the plates, and there is a screw passing upward through one of the slots
and entering the arm pivotted to the plate containing the alots; a spring is
attached to a shoulder on the plate and also connected to the arm pivotted to that
plate. The arms bow outwardly somewhat, their forward ends being nearer
together than the parts immediately behind them, it being intended that the
forward parts of the arms should be parallel when the said arms are forced apart.

page_text: in the manner and for the purpose hereinafter referred to; when these arms are
not actuated they rest against the shoulders on the plates and are retained
yieldingly there by means of the springs. These arms therefore may not only be
made to diverge, but may also be adjusted laterally on the rod by loosening the
screws and shifting the plates for that purpose.
A rack is connected to, and carried by, the carriage, and rollers are also
connected to the said carriage. There is a spur-wheel mounted on a shaft, and
engaging the rack. There are shafts turning in suitable bearings and a belt
wheel is rigidly mounted on one shaft. Loose belt wheels are on the same shaft.
A cog-wheel is rigidly attached to one side of one of the latter wheels and there is
a spur wheel or pinion rigidly attached to the shaft and engaging the spur wheel.
Cog wheels are rigidly attached to the shaft; one of these wheels engages the cog
wheel and the other engages the spur wheel. A drive belt passes about the belt
wheel, there is a pivotted lever carrying fixed studs or thimbles, and cam-shaped
extensions are rigidly attached to a shaft and arranged for contact with the said
studs or thimbles as the said shaft rotates. The belt when driven continuously in
the same direction, while on the wheel, turns this shaft and the wheel and the
latter rotates the spur wheel which in turn moves the carriage and the parts
mounted thereon. As the shaft rotates the extensions or cams strike the studs
and shift or vibrate the lever thereby carrying the belt to one of the loose wheels
and holding it there, it being understood that the said belt passes freely through a
doop or staple on the free end of the lever. As soon as the belt passes to this.
wheel, it, as well as the three other wheels are rotated, the latter in such a
direction as to reverse the direction of rotation of the spur wheel thereby reversing
the movement of the carriage and reciprocating it automatically. The function of
this part of the driving gear is to reverse the direction of movements of the arms
but any well known or suitable automatic reversing gearing may be employed for
the same purpose, although that described may be employed with great advantage
in machines of this class.
I provide a tilting lever having a cam-shaped upper edge, and rollers are
arranged to operate upon the cam-shaped edge of the lever in the manner herein-
after explained a loop or staple is applied to the lower end of the lever, a rod
turns in bearings in the frame of the machine, and arms are adjustably attached to
the said rod, and provided on their outer or free ends with thimbles or loose
sleeves. There is an arm depending from the rod and passing through the loop
freely. As the lever is tilted up and down, the arms are raised and lowered, or
also tilted or rocked, occupying vertical position when the end of the lever next
to them is lowered, and an inclined position when the lever is raised; when these
arms stand vertically the thimbles are in the position to strike the inner edges of
the arms and spread them apart sufficiently to make the forward portions of those
arms parallel; this contact of the thimbles with the arms takes place near the
central part of the latter; when the lever rises the thimbles move downward and
out of the way of the said arms, which are then drawn to their original position
by means of the springs attached thereto. In other words the arms have an
opening and closing or expanding and contracting movement, the purpose of which
will be hereinafter explained.
Uprights are secured to the frame and there is a rod vertically adjustable
therein and fingers laterally adjustable on the said rod. There is a frame consisting
of vertical rods, of a horizontal rod, and of a cross-bar; fingers are adjustably
applied to the horizontal rod. The first named fingers, by preference, are cylindrical
and the other fingers are grooved or crescent-shaped in trausverse section to receive
the first fingers. The rods move in boxes rigidly attached to a cross-piece forming
a part of the frame of the machine. There is a rod passing freely through the bar
and headed or enlarged on its lower end; the upper end of this rod is jointed or
connected to the lever and a roller is connected to the rod. When the lever
descends, the frame and the parts mounted thereon or attached thereto, also descend
until supported by the cross-bar; as the said lever ascends the headed end. of the

page_text: rod lifts the frame and the parts attached thereto. By this means one set of
fingers are carried to and from the other fingers. The function of the fingers is to
hold the mouth of the bag open while the bag is being turned. The descent of
the frame may be aided, either by springs or by means of a weight but usually
neither of these aids will be necessary.
I provide rollers the perimeters of which meet in a line in the plane in which
the arms move; the upper one of these rollers should yield slightly in a vertical
direction. The travel of the carriage is such as to carry the outer ends of the
arms to the rollers; a buffer is arranged to be struck by the end of the rack just
before the latter reaches the end of its stroke; a cam-block is on the upper edge
of the rack, and there is a table or platform preferably removable.
The machine as thus far described is complete in its construction and operation,
but as
employ a fly attachment in connection therewith, I will now describe that
attachment.
There is a fly and a shaft to which it is rigidly attached, the said shaft turning
in suitable bearings in the frame; there is a wheel or pulley upon the said shaft,
and a grooved segment on the same shaft. A cord or rope is attached at one
end to the pulley; the other end of this rope passes through the floor and has a
weight attached thereto. There is a pivotted arm or lever carrying a pulley and
a cam or curved arm rigidly attached to a shaft. A rope or cord is attached to
the rear or lower end of the segment and passing thence forward and around the
pulley and thence back to an upright to which it is attached. Another pulley is
also carried by an arm; this pulley is arranged to be struck by the cam,

This Invention relates to machinery for turning or reversing bags or sacks after
the seams have been sewn in the manufacture thereof, the object of the said turning
or reversing being to cause the seams to be inside instead of outside the bags or
sacks. The said machinery also presses the said bags or sacks and places them in
piles when they have been turned:

Similar letters of reference indicate corresponding parts throughout the drawings
A indicates the stationary part or main frame of the machine, B a travelling or
D a
reciprocating frame or carriage. C, C, bag-turning or reversing arms.
transverse rod supported in and carried by the carriage B, E, E plates mounted
on the rod D and attached adjustably thereto by means of set screws a, a,
and a¹ a¹ segmental slots in the forward parts of the plates E, E. The arms C, C,
are pivotted at their rear ends to the rear parts of the plates E E. as shown at b
and screws 6 pass upward through the slots a' and enter the arms C pivotted to
the plates containing the slots

page_text: F indicates a spring attached to a shoulder on the plate E and also connected to
the arm C pivotted to that plate. These features of construction relating to the
manner of applying the arms C, C, to the carriage B are clearly shown in Figures 2
and 3; and, on reference to Figure 1, it will be perceived that the arms bow
outwardly somewhat, their forward ends being nearer together than the parts
immediately behind them, it being intended that the forward parts of the arms
should be parallel when the said arms are forced apart in the manner and for the
purpose hereinafter referred to. When these arms are not actuated they rest
against the shoulders on the plates E E and are retained yieldingly there by means
of the springs F F. These arms therefore may not only be made to divurge but
may also be adjusted laterally on the rod D by loosening the screws a a and
shifting the plates E E for that purpose.
G indicates a rack connected to and carried by the carriage B and H H are
rollers also connected to the said carriage. I indicates a spur-wheel mounted on a
shaft I and engaging the rack G. J and J indicate shafts turning in suitable
bearings, K a belt wheel rigidly mounted on the shaft J, and K' and K¹¹ loose belt
wheels on the same shaft
L indicates. a gear wheel rigidly attached to one side of the wheel K" and
L' a spur wheel or pinion rigidly attached to the shaft J and engaging with the
wheel I. as shewn in Figure 13 M, and M', are gear wheels rigidly attached to the
shaft J; the wheel M engages with the wheel L and the wheel M³ engages with
the wheel I. A driving belt N passes over the wheel K.
O indicates a pivotted lever carrying fixed studs or thimbles 01 0¹, and
P, P, indicate cam shaped extensions rigidly attached to the shaft I and arranged
for contact with the said studs or thimbles as the said shaft rotates. The belt N
when driven continuously in one direction, while on the wheel K, turns the shaft J¹
and the wheel L' and the latter rotates the wheel I, which in turn moves the
carriage B and the parts mounted thereon. As the shaft I rotates the extensions
or cams P P strike the studs 0'0' and shift or vibrate the lever O thereby carrying
the belt N to the wheels K¹¹ and holding it there, it being understood that the said
belt passes freely through a loop or staple c on the free end of the lever O, as
clearly indicated in Figures 10 and 11. As soon as the belt passes to the wheel K¹¹
that wheel as well as the wheels LM and M' are rotated the latter in such a
direction as to reverse the direction of rotation of the wheel I thereby reversing
the movement of the carriage B and reciprocating it automatically. The function
of this part of the driving gear is to reverse the direction of movement of the
arms C, C, but any well known or suitable automatic reversing gearing may be
employed for the same purpose although that described may be employed, with
great advantage in machines of this class.
R indicates a tilting lever having a cam-shaped upper edge. The rollers H, H,
are arranged to operate upon the cam shaped edge of the lever R in the manner
bereinafter explained; a loop or staple d is applied to the lower end of the
lever R.
S indicates a rod turning in bearings in the frame of the machine and
S¹, S¹, indicate arms adjustably attached to the said rod, and provided on their
outer or free ends with thimbles or loose sleeves e e. T is an arm depending from
the rod S and passing through the loop d freely. As the lever R is tilted up and
down, the arms S' S₁ are raised and lowered, or also tilted or rocked, occupying a
vertical position when the end of the lever next to them is lowered and an inclined
position when the lever is raised, as is clearly indicated by the broken and full
lines respectively in Figure 8. When these arms stand vertically the thimbles e e
are in the position to strike the inner edges of the arms C, O, and spread them
apart sufficiently to make the forward portions of those arms parallel; this contact
of the thimbles with the arms takes place near the central part of the latter;
When the lever R rises, the thimbles e e move downward and out of the way of
the said arms, which are then drawn to their original position by means of the
springs attached thereto. In other words the arms C, C, have an opening and

page_text: closing or expanding and contracting movement, the purpose of which will be
hereinafter explained.
A¹ A¹ indicate uprights secured to the frame A, B₁ a rod vertically adjustable
therein, and C, C¹, fingers laterally adjustable on the said rod. Di indicates a
frame consisting of the vertical rods ff, of the horizontal rod, f1, and of the cross
bar C, C indicate fingers adjustably applied to the rod 1. The fingers C¹ C¹
by preference are cylindrical and the fingers O C₁ are grooved or crescent-shaped
in transverse section, to receive the fingers C¹; C', as is clearly indicated in
Figure 9. The rods ff move in boxes g, g, rigidly attached to a cross piece g¹
forming a part of the frame of the machine. E¹ indicates a rod passing freely
through the bar f¹¹, and headed or enlarged on its lower end; the upper end
of the rod E¹ is jointed or connected to the lever R. F¹ indicates a roller
connected to the rod f'. When the lever R descends, the frame D¹ and the parts
mounted thereon or attached thereto also descend until supported by the cross
bar g¹; as the said lever ascends the headed end of the rod E¹ lifts the frame D'
and the parts attached thereto. By this means the fingers C" C" are carried to
and from the fingers C'C', with the result hereinafter described. The function of
the fingers C C and CC is to hold the mouth of the bag open while the bag is
being turned. The descent of the frame D¹ may be aided, either by springs, h, h
or by means of the weight h¹, but usually neither of these aids will be necessary.
GG indicate rollers the perimeters of which meet in a line in the plane in
which the arms C.C move; the upper one of these rollers should yield slightly
in a vertical direction. The travel of the carriago B is such as to carry the outer
ends of the arms C, C, to the rollers G¹ G¹. H₁ indicates a buffer arranged to be
struck by the end of the rack G, just before the latter reaches the end of its stroke,
I is a cam-block on the upper edge of the rack G, J is a table or platform,
preferably removable and K is the main driving shaft.
The machine, as thus far described, is complete in its construction and operation
but as I employ a fly attachment in connection therewith, I will describe that
attachment briefly before describing more fully the operation of the main parts of
the machine or those parts which constitute the principal features of my invention.
L indicates a fly, and L a shaft to which it is rigidly attached, the said shaft
turning in suitable bearings in the frame A. M" indicates a wheel or pulley upon
the said shaft and N¹ a grooved segment on the same shaft. 11 indicates a cord
or rope attached at one end to the pulley M"; the other end of this rope passes
through the floor and has a weight attached thereto. P¹ indicates a pivotted arm
or lever carrying the pulley P Q indicates a cam or curved arm rigidly attached
to the shaft 1¹. R¹ indicates a rope or cord attached to the rear or lower end of
the segment N¹ and passing thence forward and around the pulley P₁ and thence
back to an upright S to which it is attached. T¹ indicates a roller also carried
by the arm P¹, the roller T" is arranged to be struck by the cam Q with the result
hereinafter described.
The following is the mode of operation of the machine now described. A
number of bags with their side and bottom seams outward are placed one upon
the other upon the table J", the open ends or mouths of the bags being towards
the fingers or bag holders C₁ C. The attendant then draws the uppermost bag
towards the said fingers until the latter enter the mouth of the bag far enough to
hold the same securely, the fingers C¹ C₁ then lying in the fingers C C as shown
in Figures 4, 8 and 9 it being understood that the machine has first been set in
operation and that the bags are to be fed forward when the said fingers are in the
position described, the operator taking advantage of the movements of the machine
to ply the bags to the bag holding fingers, one after the other. By the time the
bags are applied in this manner the fingers CC, drop or fall away from the
fingers C C thus stretching the mouth of the bag open and holding it by tension,
the descent of the fingers CC being permitted by the tilting movement of the
lever R when actuated by the roller H on the carriage B during the movement of
the latter towards the said fingers, the frame D¹ being supported by the rod E¹

page_text: с
attached to the said lever, as already described. When the roller H strikes the
cam of the lever R in this manner, it tilts down that end of the lever which it
strikes, and the lever is, owing to the shape of its cam portion, retained in this
.position while the carriage B advances. As the carriage B advances the arms C C
are carried forward and past the thimbles e, e, and the forward ends of the arms
strike that part of the bag supported by the fingers C¹C". The continued forward
movement of the arms C C forces or carries the bag through its mouth and it is thus
reversed, bringing the seams upon the inside of the bag. The contact of the
thimbles e e with the contracted parts of the arms C C spreads these arms apart so
that the bag is thereby drawn out or stretched laterally, it being remembered that
the thimbles ee are thrown up for contact with the said arms at the same
time that the fingers C" C" are allowed to drop. The position of the
fingers C¹ C¹C C₁, thimbles e e, arms C C, cam or lever R and rollers H H
with relation to each other at the completion of the reversal of the bag is
clearly shown in Figure 6. By this time the bottom of the reversed bag meets
the rollers G¹ G¹ which rotate in such a direction as to draw the bag from
the arms C C and fingers C₁ C, the latter rising or yielding, if need be, to permit
the disengagement of the bag. In reversing bags of fine or delicate texture, I
employ the cam block 1" in conjunction with the roller F¹ for the purpose of
raising the fingers C" C₁ by a positive movement, in order that the bag may be
easily detached from the bag holding fingers. The buffer H¹ aids in stopping the
forward movement of the carriage B and helps to start it in the reverse direction
from that described. The form of the cam projections on the upper edge of the
lever R is such that after the carriage B has retreated some distance the rollers H H
permit the said lever to assume a horizontal position, and retain it in that position
until the opposite cam upon the lever is reached by the roller H located for contact
therewith, and that end of the lever is thereby depressed and the other end raised.
This change in the position of the lever R throws the thimbles ee down away from
the arms C in time to allow the latter to be drawn towards each other by the
springs F F, so that the said arms after leaving the bag will assume a position for
entering the next bag, and the fingers C C are also raised up to the fingers 01 C
so that the next bag may be applied to them with facility as before described; in
Figure 4 the parts there shown are represented in the position they occupy when
the fingers CC are ready to receive the bags, it being understood that the
machine may be a "double header" or adapted to operate at both ends. It is
also to be understood that the machine is automatically reversible in any well
known or suitable way, but by preference by the means already described.
When the bags are presented to the rollers G¹ G¹, the fly L is in the position
indicated by the dotted lines shown (at L") in Figure 4 being there held by reason
of the contact of the cam Q with the roller T¹ which contact is then such as to
hold the lever P¹ in the position shown in Figure 6, the pulley Pu then being in
such a position that the cord R' will hold the fly to receive the bags. When the
machine is reversed the cam Q moves in such a direction that the weight upon
the cord O will shift the fly into the position shown by the full lines (at L") in
Figure 4 thus depositing the bags in a pile either upon the floor or upon a fly
table arranged to receive them, it being understood that the rotation of the
rollers GG carries the bags through between them and that the bags then slip
down upon the inclined fly.
It will be perceived from the foregoing description, that the bags will be
reversed with facility and also fully and evenly stretched out in a lateral direction
and pressed and neatly piled in order.
In presenting the bags to the rollers G₁G' the arms CC may strike those rollers
with sufficient force to produce a succession of blows attended with noise and a
jarring of the mechanism, unless great care be taken in arranging and adjusting
the parts. To avoid these blows I deem it best in practice to employ auxiliary
rollers or rotary blocks Q¹¹ G", shown in Figures 14, 15 and 16. These blocks
|have india-rubber peripheries, or are covered with some yielding material and áre

page_text: rigidly mounted on rotary horizontal shafts GG which are geared together
and rotated by means of any suitable driving gear which will rotate the said
blocks with equal speed and in agreement with the rollers G¹ G¹. The rollers or
blocks GG are arranged one pair or set above the other the peripheries of the
upper pair being in or nearly in contact with the peripheries of the lower pair ;
the blocks are also such a distance apart on their shafts that the turners CC
will pass outside the blocks, or so that the blocks will be between the turners as
the latter present the bags to the strippers, it being understood that the
blocks GG are also arranged directly in front of the rollers G¹ G¹ and as near
to them as may be practicable all of which is clearly indicated in Figures 14, 15,
and 16
By this means the turners C C need not strike the rollers G' G¹ in order to
deliver the bags to them for the bags will be carried between the upper and lower
sets of rollers G" G", and the latter will feed the bags to the rollers G' G' or
insure the feeding after the turners C C begin to retreat, though I deem it best
to have the turners move as closely to the rollers G³ G¹ as may be done without
producing the jar referred to.
