make envelopes having the top ?aps thereof
gummed for sealing or having said ?aps un
gummed for use in carrying second class mail.
‘In the latter case the entire gumming and dry

For making envelopes whose top ?aps have
on by means of a set screw BID. The bracket
6| pivotally supports a lever 53 which carries
a roller 64 at one end, and which has its op
right hand end of Figure 1. The ‘blanks, are - posite end connected to the bracketby means
taken one by one from the stack by means of a of a spring 66. The spring acts to press the
gum applied to them the fresh blanks are in
troduced in stack form from a table I at the
separator disc 2 having friction ?ngers 3 pro
truding beyond its surface and a ‘cooperating
friction shoe la, as disclosed in Letters Patent
of the United States No. 1,385,468, granted to
10 Charles F. Pflanze on July 26, 1921. ‘This mech
anism deposits the blanks‘ singly upon a conveyor
belt 4 and beneath rollers 5 and guide bars or
frames 6. The ‘conveyor belt 4 travels at such
slow speed that the blanks are overlapped or
shingled upon it, being arranged in fanned out
relation and being carried forward slowly by
roller down against the blanks supported by
belt 31.
,
At this point the blanks have had their seal
ing ?aps gummed and dried and are in fanned
‘out relation. They are ready for delivery to the 10
mechanism for gumming and folding the side and
bottom ?aps and for folding the sealing ?aps.
At times, however, it is desired to use the ma
chine for making envelopes for carrying second
class mail matter, and in such case it is not de
sired to gum the top ?aps. While the mechanism

adapted to be secured in various adjusted posi
25 tions by means of a set screw I2.
By adjust
ing the bracket 9 along the bar II the roller 1
may be located at the proper distance (sub
stantially a blank length) from the line of con
tact of rollers 2a and 2b which coact with the
30 cylinder 2 in removing the blanks from the stack
and feeding them rapidly away.
Beyond the
rollers 5 the bl nks pass beneath a pair of par
allel belts l3 w ch run upon pulleys i4, i6 and
i6, and which pass around a drum l1 in posi
35 tion to bear against the conveyor belt 4. From
the drum l1 the blanks pass onto a wide belt
[8 that runs upon a cylinder l9 and upon pul
' leys 20, 2i and 22.
The blanks are held against
the belt 18 by the belt 4 for part of their travel
40 around the cylinder l9, and then by two narrow
belts 23 which run upon pulleys 24, 25, 26, 21,
26 and 28. In the course of their travel around
the cylinder 19 the blanks come beneath a sum
mer 30 which applies gum to the exposed trail
45 ing margins of the blanks (the top or sealing
?aps). The blanks are delivered by the belts 18

driven by sprockets 33 and 34. Rails or skids
50 35 ‘support the upper stretch of the chains 32,
and an air chest 36 blows air against the
gummed faces of the blanks from below. The
belt 32 travels at a slightly higher speed than the
belts l8 and 23, and hence serves to fan the
55 blanks out a little more, so as to avoid liability
of two or more of the blanks sticking together.
- The means for taking the blanks into the side
?ap folding and gumming mechanism comprises 25
a disc 60a having friction studs 5|a thereon, a
wide roller 62a, and narrow rollers 53a which
cooperate with the roller 52a. The mechanism is
like the similar separator mechanism disclosed
in Figure 1. Provision is mode of a support 64a 30
above the table 48 on which a shelf ortable
65a may be mounted for supplying blanks to the
separator mechanism 60a—63a. When fresh
blanks are to be fed from a stack to the sepa
rator mechanism, the bar 49 is removed from
the machine and the table 55a is put in place.
Provision is made of means adjustable to bridge
the gap between the conveyor 31 and the separa
tor mechanism 5lla--53a or to bridge the gap
between the table 550. and the separator mech (0
anism. To this end provision is made of brack
ets 66 having slots 51 therein. The brackets are
adapted to be ?xed in position by screws 58 that
pass through the slots and nuts '69 threaded on
the ends of the screws. When the nuts 59 are
loosened the brackets may be moved bodily and 45
adjusted angularly to place a shelf 60 carried by
\them either in position to form a continuation
of the belt 31 or in position to form a continua
tion of the table 5511. A leaf 6| is hingedly con 50
nected to the shelf 60 to bridge the space be
tween the shelf 60 and the disc, 50a. A screw
62 threaded through a fixed bar 63 bears against
the under side of leaf 6| and may be adjusted
to locate the forward end of the leaf 6| at just
tion to hold the blanks against shifting while

from beneath the belts 42, they continue upon
the belt 31 to the roller 40, the stretch of belt
70 31 between cylinder 41 and roller 46 being sup
ported by a table 43. A bar 49 detachably mount

The ?ngers 66 engage the blanks at the junctions

accurately time the blanks. Hold-down bars 68 70
are provided in opposition to-the chains 64, and
any suitable means may be provided for support

ends thereof. From the conveyor chains 64 the
blanks pass a scoring mechanism 69 which forms 75
