`Examiner's Amendment
`
`1.
`
`An examiner's amendment to the record appears below. Should the changes and/or
`
`additions be unacceptable to applicant, an amendment may be filed as provided by 37 CFR
`
`1.312. To ensure consideration of such an amendment, it MUST be submitted no later than the
`
`payment of the issue fee.

`Applicant's representative, Lucian (Wayne) Beavers, authorized this examiner's
`
`amendment by telephone on July 30, 2020.

`
`The application has been amended as follows:
`
`IN THE SPECIFICATION:

`
`As shovm in Figs. 1 and 5 the workim:: drum 6 has a drum rotafamal axis which
`
`is the rotational axis of shah 15. As also shown in Fir_s. 1 and 5 the driven pulley 13
`
`is also mounted on the shaft 15 and thus has a driven pullev rotational axis \vhich is
`
`paraUel __ and_ co-axial_ withJhe _rotational __ axes_ ot'_lhe_ working __ drnm_ 6 _andJhe _shah_ 1_5.
`
`As shovvn in Pigs. 1 and 5 the drtve pulley 11 has a drive pullev rot,1tional axis ·which
`
`is the rotational axis of the shall 17 on vvhich the drive pulley is 1noumed. As further
`
`shown in Figs. l and 5 the drjve pulley 11 and the driven pullev 13 are aligned with
`
`each other in the direction that the drive belts 30 extend, and the rotational axes of the
`
`drive pulley 11 and the driven nullev 13 me vmaDel to each other. And as is shov,in in
`
`Fig. 1 an output axis of the drive engine 10 is aligned with an input axis of the

`
`Add the following ne\v paragraph between lines 42 and 43 of column 5:
`
`As shown in Fig. •) an output axis of the drive en£Iine 10 is aligned with an input
`
`axis of the dutch 14 and with an input axis of the i:.hive pulky 11 prior to operation of
`
`the construction machine. The mticulated coupling device 20 accommodates a lack of
`
`mecise alignment betvveen the output axis of the drive erndne 10 and the input axes of
`
`the clutch 14 and the drive pullev 11 due to dvnamic movement of the drive engine
`
`10 relative to the second group 5 during operation of the construction machine.
