auxiliary feeder are timed to engage the'blank
‘in advance of the pins of the main feeder, but
torbe overtaken by the latter and- to give up
control of the blank to them after the blank has
been set in motion. In this way the impactof

__ Figure l is a view in sectional, side elevation
of a portion, of an envelope machine embodying
55 lieatureslof thepresent invention, the ‘section vloe
the-table members ‘I and 8; Bars III are disposed
blanks to’ exert a frictional retarding influence
on said blanks. Provision is made of an aux
,iliary, feeder for starting the blanks'into'motion,
which feeder, comprises chains l2 and I3 that 50
carry pins l4 and I5. Provision is also made of
a pair of timing and aligning feeders which com
Iprise' chains I6 and I1 and pins l8 and IS. The
fcha‘ins l2 and I3‘travel a little slower than the
‘chains: I?and I], but are so“ timed that a pair
2
2,101,268
of pins I4 and I5 engages the blank ahead of a
pair of pins I8 and I9. This condition is illus
trated in Figures 1, 4 and 6. The timing and
relative speeds of the main and auxiliary feed
ers are such, however, that a pair of pins I8, |9
will overtake the blank and move it out of en
gagement with the pins I4, I5 before the blank
has reached the ends of the active stretches of
the chainslé! and I3. This condition is illus
trated in Figure 5.
The spacing between successive pins I8, I9 of
chains I6, I‘! is slightly greater than the specing between the pins I 4, I5, respectively, of chains
I2, l3, the relation of the spacing being as 10 is
15 to 9. The sprockets 38 and Ilb by which chains'
applied at either end of the shaft to rotate it.
The shaft 3| has a threaded portion 34 which is
effective to adjust the table ‘I and the feeder
chains I2 and I6 laterally of the machine. A
bracket 35 is slidingly mounted on the cross bar
22. The bracket 35 extends longitudinally of the
machine. The threaded portion 34 of the shaft
3| has screw engagement with members 36 fast
on the bracket 35. Rotation of the shaft 3| in
one direction is effective to carry the bracket
- 35 toward one side of the machine, while rota 10
tion of the shaft 3| in the opposite direction is
effective to carry the bracket away from such
side of the machine.
The bracket 35 interflts
with ‘the hub portion 31 of a sprocket 38 where 15
I6, H are driven are larger in diameter than the ‘ by the chain I6 is driven. The hub 31 is moved
sprockets 4| and I31)‘ which drive the chains a longitudinally of shaft 25 by adjustment of the
I2, I3, the ratio of the diameters of these sprock
bracket 35. The hub 31 is rotatable with the
ets being also 10 to 9. By reason of this, the shaft 25, rotation being effected through a key
20 speed of chains l6, I7 is greater than the speed
connection, the keyway being indicated in dot 20
of chains. I2, I3, namely, in the proportion’ of ted lines at 39 in Figure 7. The bracket 35 sim
10 to 9. The pins are so positioned on their re
ilarly interfits with the hub portion 40 of a
spective sets of chainsthat the slower moving sprocket 4| which drives the auxiliary feeder
pins I4, I5 engage the blank slightly in advance chain I2. The sprocket is adjustable longi
25 of the engagement thereof by the faster moving tudinally of the shaft 24 by adjustment of the 25
pins l8, I9, as indicated diagrammatically in bracket 35, but is connected to be driven by the.
Figure 4. By reason of the spacing and rela
shaft 24 through a key 42 carried by the hub 40
tive speeds of the above sets of pins, this condi
and a keyway 43 that extends longitudinally of
tion will be repeated each time a blank is de
30 livered from the hopper to the chains for align
ment. The shafts 24 and 25 on which the sprock
ets for the two sets of chains are mounted are
rotated at constant speed and at the same num
35
.49
ber of revolutions per minute.
It will be understood that the proportions
above given are approximate and that wide vari
ations may be made in practice from the values
above given.
The machine includes a frame comprising side
members 20 and 2| for supporting the table mem
.bers l, 8, the plate 9, the chains I2, I3, I6 and
I1, and the driving means for the chains. A
cross bar 22 spans the space between the frame
members 20 and 2| and is ?xedly connected
455 to said members. Shafts 23, 24 and 25 also ex
tend across the machine and are journaled in
the side members 20 and 2|.
The shaft 24 has
a bevel gear 26 ?xed upon a reduced portion
thereof. The chains l2 and I3 of the auxiliary
.50 feeder are driven through bevel gear 26 and shaft
24. The shaft 25 has a bevel gear 27 ?xed upon
a reduced portion thereof. The chains I6 and I‘!
of the main feeder are driven through bevel gear
27 and shaft 25.
55
A longitudinally extending bracket 28 is ?x
edly mounted upon the cross bar 22 and rests
upon, inter?ts with, and partially surrounds hub
portions of sprockets Ila, I31) and I'Ib, ?xed re
spectively upon the shafts 23, 24 and 25. The
bracket 28 has ?xed upon arms 28a thereof a
plate or block 29 having track grooves formed
therein for supporting and guiding the chains I3
and IT. The bracket 28 also supports the table
member 8 and a strip 30 of the table. The
.65 bracket member 28 is not laterally adjustable,
but is ?xed on the cross bar 22, and hence ?xes
the positions of the feeder chains I3 and I1 lat
erally of the machine.
A shaft 3| extends across the machine and is
70 journaled in the side frame members 28 and 2|.
The shaft 3| passes through the bracket 28 and
has collars 32 ?xed upon it at opposite sides of
said bracket, so that the shaft is held against
longitudinal movement. The shaft 3| is provided
.75 with polygonal ends 33 so that a wrench may be
the shaft.
The bracket 35 also surrounds a reduced sleeve 30
portion 44 of a sprocket 45 which is mounted
upon shaft 23 and which has driving connection
with the shaft by means of a key 46 carried by
the sprocket and a keyway 41 formed in the
shaft. The chain I6 runs upon the sprocket 45. 35
A sprocket 48 is journaled upon the reduced
sleeve portion 44 of’ sprocket 45“ and is held in
bearing engagement with the outer face of the
bracket 35 by means of a collar 49 made fast
upon the sleeve portion 44. The sprocket 48 .49
turns freely upon the sleeve portion 44 and the
chain l2 of the auxiliary feeder runs upon the
sprocket 48. It will be seen that adjustment of
the bracket 35 laterally of the machine is effec
tive to adjust chains I2 and I6 in unison with .45
out disturbing the operative relation of such
chains to the means for driving them.
A track member 50 is ?xed upon the bracket
35 and provides trackways for the chains I2
and I6. Table member ‘I is mounted upon out 50
reaching arms 5| of the bracket 35 and upon the
track member 50. A strip 52 of the table is also
mounted upon the track member 50. The cen~
ter plate 9 is ?xedly mounted upon a center
bracket 53, and the bracket is adjustably secured .55
in place upon the cross bar 22 by means of a
set screw 54 and a lock nut 55.
The bracket 35 includes an arm 56 having
a vertical slot 51 therein. A guide roller or
sprocket 58 for the chain I6 is journaled upon .60
the shank of a bolt 59 that extends through the
slot 51. The bolt 59 is adjustable along the slot
51 and may be secured in place by means of a
washer 60 and a nut 6| to maintain the chain l6
under the desired degree of tension. Provision £15
is similarly made on the bracket 28 for guiding
the chain I1 and maintaining it under the degree
of tension desired.
At the delivery end of the chains I6 and I‘!
the envelope blanks pass over a pair of rollers
62, 63 across a table 64. The blanks pass thence
between feed rolls 65 and 66 across a table 61
and between rolls 68 and 69 which constitute a
scoring couple. From the scoring couple 68, 69
the blanks pass to other instrumentalities for 76

I have described what I believe to be the best
embodiment of my invention. I do not wish,
however, to be con?ned to the embodiment
shown, but what I desire to cover by Letters Pat
ent is set forth in the appended claims.
I claim:
1. In an envelope machine, in combination, a
10 table, a feeder for accelerating a blank on the
table from a state of rest, said blank having re
entrant corners in its trailing edge comprising
a pair of endless chains and pins carried by the
chains and engageable with the trailing edge of
15 the blank to initiate its forward movement, said
pins engaging said blank at points other than
said re-entrant corners, and a timing and align
ing feeder operated at a higher speed than the
?rst mentioned feeder, and comprising a pair
20 of endless chains and pins on the chains for
overtaking the blank, engaging the trailing edge
thereof gently in said re-entrant corners, and
taking over control of the blank from the ?rst
feeder, the chains of each feeder being rela
25 tively adjustable laterally of the machine.
2. In an envelope machine, in combination,
a table, a feeder for accelerating a blank on the
table from a state of rest, said blank having re
entrant corners in its trailing edge comprising
30 a pair of endless chains and pins carried by the
chains and engageable with the trailing edge of
the blank to initiate its forward movement, said
pins engaging said blank at points other than
said re-entrant corners, and a timing and align
35 ing feeder operated at a higher speed than the
?rst mentioned feeder, and comprising a pair
of endless chains and pins on the chains for
overtaking the blank, engaging the trailing edge
thereof gently in said re-entrant corners, and
taking over control of the blank from the ?rst .
feeder, the chains of each feeder being relatively
adjustable laterally of the machine, one chain
of each feeder being ?xed laterally of the ma
chine, and the other'chains bearing a fixed rela
tion to one another, and being adjustable in
‘unison laterally of the machine.
3. In an envelope machine, in combination,
a table, a feeder for accelerating a blank on the
table from a state of rest, said blank having re 10
entrant corners in its trailing edge comprising
