ROBERT G. CAMERON, OF SAN ANTONIO, TEXAS.
LOCK.Specification of Letters Patent. Patented Sept. 30, 1919.
Application filed February 27, 1919. Serial No. 279,573.To all whom it may concern:
Be it known that I, ROBERT G. CAMERON,
a citizen of the United States, and a resident
of San Antonia, in the county of Bexar and
5 State of Texas, have invented certain new
and useful Improvements in Locks, of which
the following is a specification.
My invention is an improvement in locks,
and has for its object to provide a device of
10 the character specified for locking the con-
trol pedals of a motor vehicle from move-
ment in either direction, the said lock being
arranged between the pedals and arranged
to simultaneously engage and lock both..
15 In the drawings:
Figure 1 is a top plan view of the rods
with the operating levers in section;
Fig. 2 is an end view;
Fig. 3 is a section on the line 3-3 of
20 Fig.2;
Fig. 4 is a perspective view of the bolt
operating cross head;
Fig. 5 is a similar view of one of the bolts;
Fig. 6 is a perspective view showing a
25 fragment of the plate through which the
pedals project.
Fig. 7 is a fragmentary side elevation of
the front portion of the floor boards and
dash of a motor vehicle showing my lock
30 in position.
In the present embodiment of the inven-
tion the plate 1 which carries the control
pedals of a motor car is fastened to the
floor boards, and the pedals 2 extend through
35 the plate. . Rods 3 are mounted to slide in
passages 4 in blocks 5 which are secured to
the under face of the plate, and each of the
said rods 3 is provided on its inner face
with a series of notches or recesses 6.
40 The rods 3 are connected with the pedals 2
in any convenient manner and each of the
blocks 5 has a flaring recess 7 on its inner
face, with the inner ends of which the notches
6 on the rods are adapted to register, as
45 shown in Fig. 3.
A lock casing 8 of suitable construction,
as, for instance, a pin lock, is arranged be-
tween the rods 3, and the bolt 9 of the lock
carries a cross head 10 at its lower end.
50 Bolts 11 are pivoted to the ends of the cross
head, and these bolts at their free ends nor-mally engage within tapering recesses 7
and are adapted to enter those notches of the
rods which are in register with the openings
7, to positively lock the rods and conse- 55
quently the pedals from movement in either
direction.
When the bolt 9 is turned by the key 12
the bolts 11 are normally thrown into the
recesses 6 or withdrawn therefrom to re- 60
lease the rods and pedals. When the key is
withdrawn from the lock with the parts in
locked position, it is obvious that the control
pedals may not be moved by unauthorized
parties. 65
As shown in Fig. 7, an angle plate 13 is
connected with the forward end of the plate
1, and this angle plate fits against the for-
ward face of the foot board 14, and is se-
cured to the foot board by one of the bolts 70
15 which connects the steering mechanism
indicated at 16 to the dash.
I claim:
In combination with the control pedals of
a motor vehicle, locking means comprising a 75
plate having at one end slots through which
the pedals operate, spaced blocks depending
from the underside of said plate at the
other end thereof and provided upon their
opposing faces with horizontally disposed 80
recesses having flaring entrance openings,
said blocks being further provided with
horizontal passages communicating with the
inner ends of said recesses, rods connected
with the pedals and slidable through said 85
passages, the opposing faces of said rods
being provided with a plurality of notches,
a lock carried by said plate between said
blocks and having a vertically extending
operating shank depending below the plate, 90
a cross head carried by said shank, and bolts
pivoted upon the ends of said cross head and
movable into said recesses and into engage-
ment with selected ones of said notches reg-
istering with the inner ends of the recesses 95
whereby to hold said pedals against move-
ment.
