BRUNO LOPEZ, OF SAN ANTONIO, TEXAS.
ROLLER-DISTRIBUTER.Specification of Letters Patent. Patented Aug. 17, 1920.
Application filed October 27, 1919. Serial No. 333,648.To all whom it may concern:
'Be it known that I, BilUNo LOPEZ, a citi-
zen of the United States, residing at San
Antonio, in the county of Bexar and State
5 of Texas, have invented a new and useful
Roller-Distributer, of which the following is
a specification.
The device forming the subject matter of
this application is a distributer of the sort
10 used on a light and relatively inexpensive
automobile of widely known construction,
and the invention aims to provide novel
means whereby friction will be reduced, a
novel spring means being employed for hold-
1.5 ing certain of the parts in place.
A mechanic may change the structure
shown and described, within the scope of
what is claimed, without departing from the
spirit of the invention.
20 In the drawings :-Figure 1 shows in end
elevation, a device constructed in accordance.
with the invention; Fig. 2 is a longitudinal
section; Fig. 3 is a plan showing the collar
and the spring.
25 The numeral 1 denotes a casing carrying
an arm 3 whereby the casing may be rocked
to adjust the timing. An insulating ring 2
is located within the casing and 'carries con-
tacts 4, alternating with. insulating strips
30 5 to form a track. Binding posts 6, in-
sulated from the casing 1, are connected with
the contacts 4. The structure above de-
scribed is more or less common and need not
be alluded to at great length. The numeral
35 7 denotes a shaft on which a collar 8 is
mounted, the same having end flanges 9 pro-
vided with notches 10 defining bendable
fingers 11. Seats 17 are fashioned in the
flanges 9 in spaced relation to the notches
40 10.. A spring arm 12 extends circumferen=
tially of the collar 8, the arm having at one
end, a transverse head 14, the ends of which
are received in the notches 10 of the flanges
9 on the collar 8. The fingers 11 are bent in-
45 wardly as shown in Fig. 1, to grip the ends
of the head 14, and thus the inner end of the
spring arm 12 is attached to.the collar 8.
The outer end 'of the spring arm 12 is pro-
vided with an enlarged head 15 having pro-
50 jections 16. - -
A ball race 18 surrounds the collar 8. The
ball race 18 is received between the fingers
16 of the spring arm 12 and thus the ball
race and parts to be described hereinafter
55 are held yieldably in eccentric relation to the
shaft 7. The part of the ball race.18 whichis opposite to the head 15 of the spring arm
12 is held, by the action of the arm, between
the flanges 9 of the collar 8, as Fig. 1 will
make manifest. The ball race 18 is located
within a second ball race including a main
member-19 of annular form, and a side clo-
sure 20 of annular form, the main member
being L-shaped in cross section as Fig. 2
will show. Anti-friction devices, such as
balls 23, ate located between the ball.race
19-20 on the one hand, and the ball race 18
on the other hand. The parts 19 and 20 of
the outer 'ball 'race are held within an an-
nular retainer 21 which is trough-shaped in
cross section. A packing 22 may be lo-
cated in the casing 1 behind the parts above
described.
It will be clear that the spring arm 12
holds the ball race .18, the ball race 19-'20
and the retainer 21 in eccentric relation to
the shaft 7 so that when the collar 8 rotates,
the retainer 21 will sweep across the con-
tacts 4.one after another, The anti-friction
balls 23 exercise an obvious function, re- E
duing wear, eliminating noise and cutting
down lubrication. The head 15 of the
spring arm 12 is adapted to be received in
the seats 17 when the arm is flexed and com-
pressed during the mounting of the ball race 8"
18 between the flanges 9 of the collar 8.
I claim:
1. In a device of the class described, a
casing having contacts: a shaft; a collar on
the shaft; inner and outer members about 9c
the collar: anti-friction devices between
said members : 'and a spring arm extended
circumferentially of the collar, the inner end
of the arm being attached to the collar, and
the outer end of the arm cooperating with 9i
the inner member to hold the outer member
yieldably in eccentric relation to the shaft
for cooperation withithe contacts.
2. In a device of the class described, a cas-
ing having contacts: a sha ft ;.a collar on the 1
shaft and including flanges having notches.
defining bendable fibers: inner and outer
members about thtr. collar; anti-friction de-
vices between said members: a spring arm
extended circimferenfially of the collar, the 1
arm having a head at one end, received in the
notches, the fingers being bent to engage the
head, and the arm being supplied at its other
end with projections between 'which ' the
inner member is received, the arm constitut-
ing means for maintaining the outer member
in operative relation to the contacts,1,349, 2s.
