I, GEORGE WILLIAM GLAZIER, of Marshalls Wharf, Lynn, in the County of
Essex and State of Massachusetts, United States of America, Mechanical Engineer,
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 :-

Similar letters refer to similar parts wherever they occur on the different parts
of the drawings.
In the drawings A, A, is the frame of the machine in bearings in which is
journaled the driving shaft B which is set in a rotary motion by means of belt
power applied to the pulley B', which is loose on the shaft and caused to be brought
against a friction clutch B" secured to said shaft when the machine is to be set in
motion. The shaft B is started by the depression of the treadle B³ pivoted to the
frame A. at a, and carries at its rear end a conical disk B which comes in contact
with and moves the pulley B₁ in frictional contact with the friction clutch B"
when the treadle B is depressed thus causing the shaft B to rotate until said
treadle is released and returned to its normal position by the influence of a suitable
spring B shown in Figs. 1 and 2, when the loose pulley B' is relieved from the
friction clutch B" causing the machine to be stopped.
6 is a pinion on the driving shaft B, the teeth of which mesh in the teeth of the
gear c on the crank shaft C, which is journaled in bearings in the frame A, A, as
shown in Figs. 1 and 2; C' is a link the rear end of which is journaled to the crank
shaft C and having its forward end pivoted to the upper end of a lever D, which is
pivoted in its lower end to a vertically movable cross bar D¹ to which the
upwardly projecting rods or posts D", D, are secured, said rods being guided in
and 3. To the upper
suitable bearings on the frame A, A, as shown in Figs. 1,
end of the link D is pivoted a similar link D having its upper end pivoted
to any stationary part of the machine, preferably to a plate or cross bar A¹ secured
to the uprights or frame A, A.
E is the head adjustably secured to the upper ends of the rods D", D", as shown.
By this arrangement a reciprocating movement is imparted to said head from the
crank shaft C.
the
F
post on
To the stationary plate A' is secured in an adjustable manner, the
top of which is secured and resting the box supporting block which is preferably

;
composed of a base block G resting on top of the post ; on the block Gare
arranged the laterally adjustable box supports G, G, preferably secured to the
base by means of screws ", " going through slots G", "G", in the box
supports G, G. The parts G, G, are preferably guided on the block G by
means of pins or pins and rolls g³, 3, on the block G going through parallel
slots G, G, in the adjustable supports G', G', as shown in detail in Figs. 6 and 7.
The parts G, G', are adjustable according to the width of the box that is to be set
up in the machine. ', g', are yielding springs secured to the sides of the box
supports G, G¹, for the purpose of holding the box in position on said supports
while attaching the end pieces to it.
The machine for feeding and pasting the end pieces is constructed as follows:
To the upper ends of the frames A, A, is secured a hollow frame II having at
its front portion a lateral dove-tailed guide H on which the angular plates or blank
guides I, I, are laterally adjustable to and from each other according to the width
of the box ends that are to be loaded between said angular plates; said plates being
preferably adjustable by means of a right and left handed screw working in nuts
on dovetailed cars ",", that form parts of the angular plates I, I, said cars
being capable of adjustment on the dove tailed guide H for the purpose stated.
The said adjusting screw is connected to a forked bracket on the bar H' so
as to be prevented from longitudinal movement although free to be turned around
its axis while adjusting the positions of the blank guides I, I.
To the hollow frame H are secured grooved guides 4, 4, the forward ends of
which serve as supports for the end blanks K, K, that are to be successively pasted,
fed to and stuck on the turned over edges k, k, of the box body K' as shown in
Figs. 4 and 11; L is the back wall for the blank K, K, which is adjustably secured
to the guides h, h, in a suitable manner so as to change its position relative to the
front edges of the plate I, I, according to the depth of the blank K that is
being used.
Mis the blank picker or feeder by means of which one blank K at a time (the
undermost in the pile in Fig. 4) is taken from the pile contained between the
walls I, I and L and carried to the box while held on the box support as shown in
Fig. 4 said feeder or picker has at its forward end, an upwardly projecting lip m
adapted to come in contact with the rear edge of the bottom sheet K in the pile
Fig. 4 and thereby carry it, one at a time, to the box support; m, m', are spring
wires or bars on the underside of the picker M which spring projects beyond
the forward edge of said picker and serve as yielding supports on which the blank
is carried to the place where it is to be stuck on the box body; said wires being
elastic will permit the blank to be depressed upon said box body by the action of
the head E.
The picker M is reciprocated by mechanism from the crank shaft Cas
follows:
On the shaft B or other suitable part of the machine is pivoted the lever N
which is actuated in one direction by means of a cam C on the crank shaft C
acting on a pin or pin and roll » ou said lever N as shown in Figs. 1, 2 and 3; a
spring N moves the lever N in an opposite direction. To the upper end of the
lever N is adjustably connected a rod m, the forward end of which is pivoted or
otherwise connected to the picker M. The pasting device for automatically
applying paste or adhesive sub-tance to the underside of the lowest blank K in the
pile is constructed as follows:
On each of the side plates I, I, are pivoted a pair of parallel links O, Q, one of
which has an extension O' through which passes loosely a transverse rod " to
which is hinged the inner end of a rod 0³ the outer end of which passes loosely
through an ear on the lever N and is provided in its outer end with adjusting
muts O as shown in Figs. 1 and 3.
To the lower ends of each set of the parallel links O, O, is pivoted a rack or
spotter bar having teeth or projections on its upper side as shown in Figs. 1, 3, 4
and 5; P is a receptacle containing paste or suitable adhesive liquid into which

page_text: the racks or spotter bars 0³, 0°, dip intermittently and transfer the paste in spots
on the underside of the blank at or near its side edges.
The said spotter bars are operated in one direction by the lever N and in the
opposite direction by means of a spring 0° interposed between the rod and a
bracket H on the plate H; the dip of said spotter bars 0 is regulated by means
of an adjustable collar 07 on the rod 0* coming in contact with the bracket H"
during the forward motion of the lever N as shown in Figs. 1. and 4. For the
purpose of applying paste in spots to the underside of the blank at or near its
forward edge, I pivot at a lateral rack or spotter bar R having slots R', R¹,
adapted to receive projections or extensions 03 on the side racks 0, 0³ by which
an up and down rocking movement is automatically imparted to the said lateral
rack or spotter bar during the forward and back swinging motion of the side
racks O³, O'.
On the rear side of the stationary bar H is arranged a vertically adjustable
gate S which is adjusted up and down by means of a suitable regulating screw S'
shown in detail in Fig. 4. In using the machine the gate S is adjusted so that its
lower edge is held in position above the bars h, h, (on which the pile of
blanks Krest) so as to permit one blank at a time to be taken from the bottom of
the pile and pushed forward by the feed bar M. In practice I prefer to provide
the gate S at its lower end with a forwardly projecting foot-piece S" adapted to
hold the blank against the lip m on the feed bar M after said lip has passed by the
gate S, and thus preventing the blank from springing or moving upwards away
from said lip. I also prefer to use a pair of forwardly projecting stationary
bars S³, S, secured to the stationary cross bar H' or frame H, or other stationary
part of the machine for the purpose of holding the blank against the lip m on the
feed bar M while being fed onto the box support as shown in Figs. 3 and 4. If so
desired the said bars S³, S', may be dispensed with and the foot S" extended
forward sufficiently to serve the purpose of and act as a substitute for said
bars S³, S3, without departing from the spirit of my invention. The presser head E
has on its underside a cavity or recess E' shown in Figs. 3 and 4 adapted to
receive the guide bara S³, S³, during its descent against the box blank and box
supports G, G'
In practice I prefer to provide the machine with an automatic stopping device
for the purpose of stopping the machine after its crank shaft has performed one
complete revolution so as to cause the head E to be raised to its highest position
when the machine is stopped after setting up the box end and for this purpose I
secure to the crank shaft C, a cam C³ having a recess or reduced portion on its
periphery as shown at C in Figs. 1, 2 and 3. In connection with such cam, I
use an upwardly projecting bar or rod 63 on the treadle B as shown in
Figs. 1, 2 and 3.
When the treadle is depressed, the machine is started as hereinbefore described
and although the operator relieves his pressure on the treadle after the machine
has been started said treadle will remain depressed by the cam C³ acting on the
treadle bar and the friction clutch B" coupled to the pulley B' until the crank
shaft Chas completed one revolution when the upper end of the treadle bar b
moves into the cam recess c by the influence of the spring B causing the treadle
to be raised, the friction taken off the pulley B' and the machine stopped auto-
matically leaving the head E in its highest position.
The operation of the machine is as follows:
The blanks K are placed in a pile between the walls or guide plates 1, I, L, and
the box body K' is placed in position on box support G, G, as shown in Fig. 4.
The machine is set in operation by depressing the treadle causing the feed plate M
to be moved backwards sufficiently to expose the lowest blank in the pile after
which the paster bars or spotters 0%, 0, R, are caused to rise and transfer the
paste in spots to the underside of the blank, after which said pasters drop into their
normal position in the paste in the box P. The pasted blank is then fed by the
plate M, while resting on the springs m', m', to the place where it is to be "set up '

page_text: or stuck onto the overlapping edges k, k, k, of the box body; the head E descends
and presses the pasted blank onto said edges of the box body; the head then com-
mences to rise to its highest position and the operator in the meantime removes the
box and reverses it on the box support for setting up its other end and so on during
the operation of the machine.
T, T, are laterally adjustable stops secured in a suitable manner to the front part
of the pressure bar or head E, said stops having their lower portions projecting
below said head and serve for the purpose of stopping the pasted end blank from
being fed too far by the picker bar and arresting it in its proper position relative
to the box body held upon the box support.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, declare that what 1
