to and normally held in engagement with
the ratchet wheel by means of the respe-
tive flat springs. 24, 24 which press against'
said dogs. It is thus obvious that' as the.
5 spur gear wheel 21 is rotated in the direc-
tion indicated by the arrow in Fig. ,6 that it
will rotate independent of the shaft 14. and
the ratchet wheel 22, but when rotated in
the opposite direction, the dogs 23, 23 will,
10 engage with the ratchet wheel 22 and force
said ratchet wheel 22 and shaft 14 to -rotate
with the spur gear wheel 21.
Projecting out from the wall of the com-
press chamber is a short shaft 25 upon
15 which is nmounted a' short rotatable sleye
26 Fixed' to. the inner end of said sleyee
and extending downwardly therefrom is a
long arm 27 and fixed'to the oter end. of
said sleeve and exten1ding downwardly
20 therefrom is an 'arm 28. The arpn 27. hasin
inwardly extending roller bearing 29 at its
lower end. This bearing projects, into a
long link 30, which is fixed to the side, of
the plunger 3.so that as the plunger' recip-
25 rocates back and forth the arms 27 and 28
are forced to move in unison therewith.
The lower end:of the arm 28ihas a dog 31
pivoted thereto. An oblong rapk member
32. is slidably mounted in bearings 33 and 34,
30 carried by the side of the compress chamber
and the upper face of this rack: member has
rack teeth 35. A strong coil spring 36 is
provided, one end of which is attached to
the front end of'the rack nfember 32 and the
35 other end of which is secured to an adjust
able hook 37 fixed to the discharge end of
the compress chamber. The dog 31 is nor-
mally held in engagement' with the rack
teeth 35 by means of a flat: spring38 which
40 is attached to the arm 28 and whose free end
rests against the upper. side of said, dog.
Upon the back stroke of the plunger, the
same operates through the mechanism just
described 'to move the rack member '32' rear
45 wardly, overcoming the tension- of the
spring 36. The outer side of the 'rack mem-
ber 32; has spur gear teeth.39 which engage
with the teeth of the spur gear wheel 21 find
as this member moves rearwardly the gear
50 wheel' 21 is rotated in the' direction indi-
cated by the arrow in Fig..6. Upon the'
forward stroke of' the plunger the dog 31 is
moved forwardly, but the rack member 32
and the spur gear wheel 21 are locked
55 against' movement by the dogs 9323' and
upon the next succeeding backward stroke
of the plunger the rack member 32 is' again
moved rearwardly as before described
Near the forward' end of the compress
60 chamber is a short vertical shaft 40 'rotatably
mounted in suitable bearings. 41 and: 42.
The lower end of this shaft has an' arm 43
which is rigid therewith and which projects-
rearwardly therefrom, whose free' end" hasa bearing 44 in which the stub shaft 45 ro- 65
tates. This shaft 45 carries. a wheel 46
rigidly mounted thereon, from the periph-
ery of which. projects.. spikes 47 which en-
gage with the bale being formed and as the
bale- moves, along in..the compress. chamber 70
the wheel. 4.6 .is. rotated.
An arm 48 i provided 'which is' fixed to
the inner -end of the sleeve 49.. This sleeve
rotates upon the shaft 50 projecting out-
wardly from the side of the compress :cham- 75
ber. The free end of the arm 48 extends
under the wheel 46 and fixed to the outer
end of the sleeve 49 and extending in the
opposite direction is.the arm 51- which ex-
tends above the disk. 18. This disk has a 80
shoulder 52 projecting out from the pe-
riphery thereof and the under side of. the
arm 51 has a corresponding shoulder 53
which normally rests against the shoulder
52 and locks the disk 18 against rotation. 85
The free end of the arm 48 has a laterally
extending roller bearing 54' and the under
side of the wheel 46 has'a cam 55. .he
roller bearing 54 is arranged in the pah of
the cam 55 and 'when said cam contacts with 90
said bearing, the' free end;of the arm .48 is
depressed:'and the free end of the arm 51 i
elevated carrying the shoulder 53 out of en
gagement with the shoulder 52.
Pivoted to the.side of the compress chain 95
ber is a bell crank formed of' the' arms 5
and' 57, the' latter 'of' which projects reai
wardly and has a hook 58- provided to en
gage behind the shoulder 52' and' tempo.
rarity hold the. disk18'against rotation when 100
the arm 51 is' disengaged from' said should
der. The arm 57 extends downwardly and
one end' of the pull spring 59 is attached
thereto and the other, end secured to the; stud
60 projecting from the chamber wall andtos
the tension of the spring tends to hold thie
arm 56 elevated and the hook 58 in engage-
ment behind the shoulder' 52.
The lower end of the arm 57' is beveled
and a hook 61 is pivoted to the arm 27 near 110
its lower end. A flat spring .62 is attached
to said arm 27 and its free .end rests against
the lower side of the hook 61. As the plun-
ger 'moves forwardly the hook 61 contacts.
with the lower beveled .end of the, arm 57 115
and is depressed thereby until it passes said
end and the push of ,the spring 62 then
causes said hook to engage over the end of
said arm and as. the plunger moves rear-
wardly, the hook-61 exerts a pullon the arm 120
57, thereby overcoming the tension of the
spring 59 and releasing the hook 58 from
the shoulder 52. The disk 18 is thus free to
rotate and the shaft '14 is released. to the
tension of the spring 36 which is exerted. 125

gear wheel'21, said spur gear -wheel rotating
in the' direction opposite of that indicated by2
