berfbgextend from the inner face of such mem
ber ajdistanceslightly less’than one-half the
thickness of" the hanger bar A and the equally
thick tongue'Z'l' of; the tooth C. Thus the ends
of said bosses and the ‘ends of the leading‘ stop
lugs I 8 on the two holder members ‘are kept
from contacting each other and-are thereby pre
cluded from intertering'i’with the rigid clamping
of said members against the hanger bar A and
said tongue 21 ‘of saidtooth'C. ‘The rearmost .
' stop‘ lugs 18 on‘ the assembled holder members b
will, however, come into contact with eachother
should the sixth clamping‘ bolt 31,‘ in the trail
ingtip portions of said members. tend to spring
‘
3
2,284,178
‘said .portions toward each other. Thus, it will
‘be seen that those .of the lugs l8 disposed at the
rear of the tooth holder 13 serve as spacers for
tooth clamped thereto, but when the seat l5 at
such ‘portion of either holder member becomes
too far worn, upon the wearing away of the
' tooth, to afford a satisfactory tooth mounting,
said holder membersb.
Although the tooth C has only the single fas
tening bolt 34 therefor, it will be readily appreci
ated that the engagement of the dual bearings
the member will be reversed to present the previ
ously trailing seat l5, if not already worn, in
leading position, and thus provide an unimpaired
29 on the tooth with the two seats i5 on the
support for one of the bearings 29 of a tooth.
When both seats I15 of a holder member b have
leading tip portions of the holder member 1),
coupled with the engagement of the tongue 2'?
been rendered useless by wear, said member will,
of the tooth with the two stop lugs l8 on said
portions of said members, results in a securely
of course, be discarded and a new one substi
?rm and durable connection'between said tooth
holder members b endwise to bring its previously -
and the holder members, without any appreci
able strain on said fastening bolt, and without
any possibility of the tooth to pivotabout said
bolt.
Upon the removal of the tooth-attaching bolt
34 and the mere loosening of the remaining bolts
clamping the holder members b together, the
tooth C may be readily removed from said mem
bers and another tooth put in its place, it being
necessary only to replace the tooth-attaching bolt
.34 and re-tighten the remaining bolts to secure
the substituted tooth ?rmly attached to said
holder
members.
‘
.
The ready attachment of the tooth C to the
companion holder members b and the correspond
ing readiness with which the tooth may be de
tached from such members, renders it easy fora
used to substitute a ‘new tooth for one worn be
yond further usefulness, and also renders it easy
for the user to interchange the teeth of scari?er
elements, when desired, as for the purpose of ob
taining uniformity of wear of such teeth.
The paired holder members b of a scarifier ele
ment are each reversible‘ end-for-end, such re
versibility of said members being desired in the
event of the wearing off of the seat l5 of either
member to an extent impairing the security of
attachment of a tooth thereto. The double
tipped construction of said holder members,
which renders possible the reversibility thereof,
provides for doubling the life of said 1members,
withinfavorable dimensional and Weight limita
tions, as will be readily comprehended.
In either end-for-end relationship of either of
the paired holder members b‘, the boss '20 will be
socketed inthe leading end of the slot l3 in the
hanger bar A, and the boss l9 Will be socketed in
the one or the other of the openings II, l2 oc
cupying the leading position in the hanger bar.
Correspondingly, the one or the other of the
bosses 2i, 22 will be socketed in the one or the
other of said openings ll, I2 in the hanger bar
tuted therefor. Upon reversing either of'the
trailing ‘seat l5 into leading position for the ap
plication of a tooth thereto, such member will, of
course, be shifted to the opposite side of the
hanger bar A.
‘
Among the numerous advantages residing in
my present invention are included simplicity and
economy of manufacture and the ease of assem
bly, disassembly and rearrangement of. parts, ‘
which permits the replacing and interchanging‘
of such parts ‘and also the reversal of the com- ‘
panion holder members to provide unworn tooth
supporting seats for those which have been im
paired through wear. The provision by which‘
the tooth structure may be practically entirely
Worn away-before being rendered useless is an
important feature of the invention. In addition
to performing its scarifying function, the tooth
guards the companion plates of the composite
tooth holder at the leading tip portions thereof
where the greatest wear is encountered. The
edgewise reversibility of the hanger bar, A and ’
the endwise reversibility of the holder membersb
simplifies initial assembly of such parts of the
sacri?er element and likewise simpli?es the sub- '
sequent rearrangement of said holder members
in the assembly to renew either or both of the,
tooth-supporting seats. The meshing‘ or inter
locking engagement of the tooth C with both of
the holder members I) affords an extremely rigid
support for said tooth and, simplifying‘the con
nection between the tooth and hanger minimizes
' the effort required in attaching the tooth to and
detaching the same from said holder.
.
Changes in the speci?c form of my invention,
as herein disclosed, may be made within the
scope of What is claimed without departing from
the spirit of my invention.
Having described my invention, what I claim
as new and desire to protect by Letters Patent is:
l. A scari?er element comprising a hanger bar,
an elongated tooth holder for attachment to said
hanger bar, and a tooth for attachment to said
holder, said hanger bar having a plurality of
openings in the lower end thereof, extending
therethrough and providing sockets at its oppo
and slot l3 in the hanger bar A renders it im
site sides, said holder consisting of two plate-like
material as to which 'one of the edges of said
hanger bar is placed in leading position and this 60 members of identical formation, the edge of each
member providing a seat at each tip portion of
fact coupled with the further fact that either
occupying the trailing position.
The relative positioning of the openings H, 12
end of either of the two identical holder members
b of a pair may take the leading position, greatly
simplifies the requirements in manufacture and
in assembly, as well.
The construction of the tooth 0, though nec-~
essarily of hard, wear-resisting material, is rela
tively inexpensive, the entire element considered,
since the major portion of the tooth structure
may be worn away before the tooth becomes use
less.
