Edward N. Jacobi, Milwaukee. Wis., assignor to
Briggs & Stratton Corporation, Milwaukee,
Wis., a. corporation of Delaware
Application August 9, 1935, Serial No.«35,493
21 Claims.
This invention relates to locks and refers par
ticularly to glove compartment locks for auto'
mobiles.
Compartments located in the dash of automo
5 biles and commonly referred to as glove com»>
partments are generally equipped with hinged
doors. It is desirable to provide locks for these
doors,.and as shown in Patent No. 2,006,922 ls
sued to Edward N. Jacobi, July 2, 1935, to com
10 bine the locks with a knob-like structure to fa
cilitate opening and closing of the door.
Heretofore, a spring catch was used to-yield
ingly hold the door `closed independently of the
lock, the lock being usedonly'to positively secure
15 the door in closed position. The lock was thus of
the “dead bolt” type. In locks of this'type, if the
bolt is placed in its locked position before the
door is closed, the projecting bolt interferes with
closing of the door and may break if the door is
20 slammed.
The disadvantages of this construction are`
manifest, and to overcome the same, this inven
tion has as an object to provide a simple, inex
pensive spring bolt type of lock, particularly ap
25 plicable for glove compartments.
A further object of this invention is to provide
a lock for the purpose described wherein release
of the bolt is eiîected by inward depression of
' the lock cylinder in the fashion of a push button.
30
Another object of this invention resides in the
provision of novel means for eliminating rattling
in a lock of this type, and to utilize the bolt
spring for this purpose.

Referring now more particularly to the accom
panying drawings in which like numerals indi
cate like parts throughout the several views, the
20
25
numeral 5 designates the door of a glove com
partment, or the like, adapted to be secured in a
closed position fixed with respect to a panel 6 in 30
which the door opening is formed by means of a
lock mechanism, indicated generally by the nu
meral 1.
Another object of this invenïon is to provide a
The lock mechanism comprises a casing 8
35 construction wherein part of the boit actuating bored as at 9 to receive a llock cylinder I0. The
mechanism is utilized to removably retain the e outer end of the casing 8 has an enlarged iiange 35
cylinder in its casing.
'
.
A further object of this invention is to simplify
the manner of attaching or mounting the lock
40 to the door or panel with which it is used.
‘
With the above and other objects in view
which will appear as the description proceeds,
this invention residesv in the novel construction,
combination and arrangement of parts substan
45 tially as hereinafter described and more particu
larly deñned by the appended claims, it being
understood that such changes in the precise em
bodiment of the herein disclosed invention may
be made as come within 'the scope of the claims.
.50
The accompanying drawings illustrate several
complete examples of the physical embodiment
of the invention constructed according to the best
modes so far devised for the practical applica
55
tion of the principles thereof. and in which:
Figure 1 is a -iongitudinal section view through
H so as to give the casing the form of a knob to
facilitate opening and closing of the door. The
outer or front end of the cylinder has the usual
head i0' disposed within a counterbore 9’. It is 40
exposed and accessible from the front of the lock
so as to permit the cylinder to be depressed lin
wardly in the manner of a push button when un
locked. Such inward depression of the cylinder
is utilized~to releasea bolt i2 projecting from 45
the inner or rear end of the casing, as will be »
hereinafter more fully described.
The inner or rear end portion of the casing is
reduced in diameter to provide a shoulder'. I3
' nich abuts the outer face of the door 5 when the 50
casing is mounted thereon with its inner end por
tion projecting through a hole I4 in the door.
The casing is secured to the door by coniining
the door between the shoulder I3 and the periph- »
ery of a retaining cup l5 telescoped over the re
2
2,086,034
duced inner end of the casing and held thereto by
a screw I6 threaded in a tapped hole in the
casing.
`
The bottom wall of the retaining' cup has a
transverse slot or opening I‘I through which the
bolt I2 projects to permit the same to engage a
keeper member I8 fixed to the panel 6. An up
turned lip I9 formed as an'integral part of the
retaining cup precludes depression of the bolt by
means of an implement inserted through the
space between the upper edge of the door 5 and
the panel 6.
The lock bolt is hooked to engage over the
keeper member I8 and has an elongated outer
15 end portion arranged to strike the keeper mem
ber I8 and permit automatic engagement of the
bolt therewith. The inner end portion of the
bolt is disposed in an open recess 20 in the inner
end of the casing where it is loosely pivoted by a
20 pin 2I. The width of the open recess 20 is such
that the bolt is guided by the opposite fiat sides
In this connection it is to be observed that the
projection 34 has an inclined or spiral shaped
edge 35 which is adapted to contact a similarly
shaped surface 36 on the inner face of the wall
23 and force the cylinder outwardly upon retro
grade rotation from'its unlocked position so as to
insure positive return of the parts to their locked
positions.
The projection 34 also has the function of pre
venting rotation of the cylinder to its position 10.
at which the lug 28 on the pusher member aligns
with the gateway 2'I of the bayonet slot in which
position of rotation, .the cylinder is removable.
The removing position of the cylinder lies be
yond its unlocked position of rotation shown in 15
Figure 2. In the unlocked position of the cyl
inder, a fiat wall surface 3T on the projection 34
lies substantially in the plane of one side of the
bolt to be engageable with an inwardly extending
toe 38 on the bolt in bothits locked and un 20
locked positions to prevent rotation of the cylin
of the recess in its pivotal movement to and from
der to its removing position except 'when the bolt
operative position to which it is yieldingly urged
is moved to a releasing position, shown in dotted ‘
by a spring 22 confined between the boltl and a
25 wall 23. The wall 23 provides a bottom for the
linesin Figure 3.
In the releasing position of the bolt, the toe 25
sertion of a proper key 25 to free the cylinder for
rotation. Four-grooves are provided so that the
key may be removed in either locked or unlocked
is moved clear of the obstructing surface 31
allowing the cylinder to be turned past its un
locked position to its removing position. Move
ment of the bolt to its releasing position requires
direct manual actuation of the bolt. The normal 30
unlocking of the bolt by depression of the cylin
der cannot move the bolt to its cylinder releasing
position as the depression of the cylinder is limit
ed by engagement of its head with the bottom of
the counterbore formed in the casing to receive 35
the head.
As soon as the cylinder is turned past its un
locked position, the toe of the bolt may be per
position.
mitted to ride on the conical outer surface 31' on
- bore 9 of stepped formation with a hole there
through coextensive with the upper half of the
open recess 20. To hold the spring against dis
placement the wall 23 has a recess to receive one
30 end of the spring and the bolt has a titprojecting
therefrom to engage the `other end of the spring.
'I'he lock cylinder I0 is provided with the usual
key operable tumblers 24 yieldingly projectable
into one of four longitudinal tumbler receiving
35 grooves 24', and retractible therefrom by the in
,
At its inner end portion, the cylinder has a
40 bayonet slot comprising an arcuate groove 26
` with a gateway 2'I leading thereto.
Engaged in
this bayonet slot is a lug 28 forming part of. a
pusher member 29. As best shown in Figure 10,
the pusher member has a main body portion 30
45 which is slidably received in a. slideway 3| cored
in the casing Wall above the open recess 20 and
extending forwardly from the extreme inner end
of the casing sufticiently far to communicate with
the bore 9 and permit the lug 28 to engage in the
50 arcuate groove 26. The forward end of the slide
way is closed by an inclined wall 4I with which
the pusher member engages to limit its forward
movement and thus, through the engagement of
its lug 28 in the arcuate groove 26, hold the cylin
der against outward withdrawal.
'I'he rear end of the pusher member engages a
shoulder 32 on the pivoted bolt so that upon in
ward endwise motion of the cylinder, the bolt I2
is rocked about its pivotal mounting against the
60 action of its spring to a releasing position.
Inward endwise motion of the cylinder, how
ever, is not possible except when the cylinder is
turned to a predetermined unlocked position,
which is the position of the cylinder shown in
v65 Figure 2. In any other position of rotation of
the cylinder, a projection 34 on its inner end
strikes the foremost step z3’ of the wall 23 and
thus prevents inward depression of the cylinder.
The projection 34 and the front face of the wall
23 are so shaped that when the cylinder is turned
to its unlocked position, its projection 34 clears
the wall part 23' and permits inward endwise
motion on the part of the cylinder until the cyl
inder head Ill’ contacts the bottom of the
counterbore 9’.
-.
the projection 34 thus obviating the necessity for
holding the bolt down in its releasing position.
By virtue of the novel arrangement and rela
tionship of the cylinder, the pusher member, and
the bolt, the bolt spring is utilized to prevent
rattling. It is to be observed that the pusher 45
member has its top wall stepped which results in
an edge 4I). 'I’his edge 40 contacts the top of the
slideway 3 I, and inasmuch as the pusher member
has a degree of play in the slideway, it is free
to rock about the fulcrum provided by the en 50
gagement of the edge 40 with the top wall of the
slideway.
Upon such rocking movement ofthe pusher
member, which is produced by the action of the
spring 22 through the medium of the cam-like
engagement between the pusher member and
bolt, the forward end of the pusher member is
pressed down onto the inner end of the cylinder.
Downward depression of the forward end of the
pusher member is further assured by virtue of 60
the fact that the pusher member is forced for
wardly against the inclined closed end 4I of the
slideway by the bolt, and the loose pivotal
mounting of the bolt insures the proper function
ing of the anti-rattle feature at all times at is
permits the spring to yieldingly urge the bolt
upwardly against the rear end of the pusher
member.
If desired, the locking bolt may be mounted in
the casing as in the modified embodiment of the
invention illustrated in Figures 11Aand 12. In
this construction, the pivot pin is eliminated and
trunnions 43 are formed integrally with the lock
ing bolt to project from the opposite sides thereof
for engagement in round bottomed recesses 44 in 75
-the side walls'of
2,086,034

>open recess 45 in the inner bolt about its pivotal axis in the opposite direc
-end of the casing. Insertion of the trunnions 43
into vthe recesses. 44 is possible through entrance
passages 46 in the side walls of the open recess
45, which passages lead to the recesses 44.
From the foregoing description taken in con
nection with the accompanying drawings, it will
_ be readily apparent to those skilled in the art that
