occasion may arise, where the projecting
lugs will not be desirable, the engine may be
stopped and the lugs manually withdrawn,
by"foring each lug-4 around -into its corre-
5 sponding slot 6, the extension 5 -ind the
hinge member 11 then assuming the posi-
tion shown in dotted lineshin Fig.'2.' Dring
this operation, the spring .14 will yield so.
-as to periiit the withdrawal of the lug, the
10 rod 12 sliding through the -orifice '13..'. When
the hinge member 11 has assumed the posi-
tion shown in dotted lines in Fig: 2; the
pressure of the spring" 14 will operate to
hold-it in said position.
15 It is' ofticourseS obvious- that any desired
number of lugs 'may be employed for' each"
rim in' accordance with the requirements of
the situation ':and it is further obvious 'that
the 'mechanical construction and operation'
20 of the lug may' be 'varied; but' I hereby 're'
serve the right to make such -mechanical
changes therein as' will:'not depart front the
principle' of the invention, as embodied in
the appended claims.
25 What I claim'is:-
1. A 'wheel of the character described
having.a rim, said 'rim being providedith
slots, a lug. projecting through each slot and'
pivoted to the ;rim so' as -to- project through'
30 or.to be withdiaawn within the rim, a lat
eral extension'carried by the lug 'and resting
in said slot'when the lug is in its projecting
position, and a resilient member operating:
in resistance to the lug, and' holding the
35 same in either of.said positions.
2. A- wheel of. the character described
having a rim,' a plurality 'of lugs pivoted to
the rim and arranged to 'project therefi-om,
said lugs. being freely movable on their piv-
40 otal supports; so as to be 'readily withdrawn
within the rim, a lateral extension carried
by each lug and resting 'in the coiresponding'
slot when its'lug is in its projecting posi'-tion, and a' resilient- member operated in
resistance to the lug and holding the same 45
in either of said positions.
3. Wdefic of" the cfraracter daeribed
including'a rim having a slot therethrough,
a lug projecting through said slot and being
pivoted to the riim, a bracket fixed to the in- 50
ner side of the rim in the rear of said lug,
a 'rod pivoted to the inner end of the lug, at
one eni and whose' other end has a slidable
engagement with said bracket, and a re-
silient member surrounding' said rod 'and 55
interposed between -said bracket and the 'in-
net'end-oftsaid=lug
4.L device of the character described in-
cluding. a- rim, a lug pivoted thereto and
normally projecting bey nd said rim, a 60
bracket fixed' to 'the 'inner side of' said rim,
in the rear of said lug, a rodpivoted:to the
inne end'of 'said lug; atone end and Whiose
other erd has a slidable 'engagernent''with
said bracket and a resilient member suK- 65
rounding 'said, rod: and interposed beti Teen
the said bracket' and the inner' end' of said
lug.
5. A device=of the character described in-
cluding a rim, having=a slot therethrough; 70
a lug projecting 'through said slot' and b'e
ing pivoted to the rim; a lateral extension
carried by said lug and resting in said slot
when' the lug is in its projecting position,
said lug'having an inward extension' and a 75
resilient nmemb'er,' oneend'of'which is 'fixed
relative tor the" rim and the other end of
Which resists 'against the inward extension
of 'said 11Wg
In testimony whereof I have signed my- 80
name to this: specification 'in the presence of
two subscribing witnesses.
