BEARING AND FRICTION LOCK Original Filed Dec. 16, 1930 Patented Aug. 14, 1934 fr Robinson H.V Harsh, Washington, D. C.
' Application December 16, 1930, serial No. 502,825
y Renewed July 2, 1934 Y4 claims.. (Creez-73) v This invention relates to furniture and more particularly to a novel drawer guide and lock.
VOne of the primary objects of my invention is to provide novel means for engaging a sliding drawer for holding the same in an adjusted posi-V tionl against accidental movement, thereby insuring the proper positioningof the drawer atI all times. c
Another important object of my invention is the provision of a friction -lock for a sliding drawer, in which the drawer can be held either in an open or closed position against accidental movement or in an adjusted partially openedv position against accidental movement. A further prime object'of my'invention is the provision of novel means for forming the vfriction lockl itself, whereby an inexpensive and durable structure will be had, which at the same time will give the maximum amount of usefulness.r j
Withv these and other objects in View, the invention consists in ythe novel construction;` arrangement and formation of parts, `as will be hereinafter moresp'ecically described, claimed, and illustrated in the accompanying drawing, in
which drawing:-
Figure 1 is a front elevation of an article of furniture showing my improved drawer guide and lock incorporated therewith, parts of the view being shown broken away and in section.
Figure 2 is detail section taken on the line 2-2 of Figure 1 looking in the direction of the arrows. Y
Figure 3 is an enlarged detail sectional view illustrating my improved drawer guide and lock.
Figure 4 is a detail sectional view taken at right angles to Figure 3 and on the line 4 4 of Figure 3, looking in the direction of the arrows.
Figure 5 is a fragmentary detail perspective view of the drawer guide strip.
Figure 6 is a detail perspective view of the casing for receiving the friction ball lock, and
Figure l is a detail perspective View of a slightly modified form of casing for receiving the ball lock.
vrfurniture A includes a body 10 having support- I of the drawer. At spaced points the bearing 'and `Vwill lbe later described.
ffl
ing legs 11, and with a drawer opening 12 in its front wall. A drawer 13 is' slidable' in the body 10 through the drawer opening 12and suitable guides 14 are provided for the drawer. n
All of the above described structure may be considered ofy conventional or ordinary construc- Ition, and my invention relates to a novel means foi` guiding the drawer during'vthe opening .and
closing thereof and for frictionally locking the y n drawer in either a closedfor opened position, and ,65" infany adjusted partially opened position.
In accordance with my invention I provide a bearing and guide strip 15, which can be Vmade of metal or-` the like and this stripis secured to .I the lower edge of the drawer 13 directly above 'Z0- 2 one of the drawer guides 14. The strip 15 preferably is made of metal and the lower edge of the drawer` israbbeted or grooved so thatthe strip can be countersunk within the lower wall u guide strip 15 is provided with struckintits 16,v which form keeper members for a purpose whichv Operating in conjunction with the guide and]v bearing strip 15 I countersink within the drawer 80 guides 14"a,casing`17,"which forms the housing for the friction lock and bearing member, as will now be described. The housing 1'7 is of a cylindrical shape and is preferably formed from sheet metal and the construction thereof forms one of 'f' the salient parts of my invention. The inner edge of the casing 17 has formed thereon a pair of diametrically disposed lingers 18 and 19. The nger 19 is bent inwardly to extend diametrically across the casing as clearly shown in Figure 6 and is of a substantially U-shape in longitudinal section and has its intermediate or bight portion indented as at 20 to form a seat for the bearing ball and friction lock Vmember 21. The other u finger 1S is now bent down and extends across 95 the lower end of the casing and engages the end of the ringer 19 at its point of connection with the casing. By this arrangement the nger 18 will serve to limit downward movement of the ..1 nger 19 and also serve to brace the casing and 100M' prevent it from being bent out of shape when it is driven into place.
The finger 19 forms a resilient leaf spring on which the ball bearing and friction lock seats and thus the finger normally urges this ball outward of the casing. The casing 17 is imbedded or countersunk within the drawer guide 14 adc jacent to the front of the drawer 13, when the same is in its closed position, so that the ball 21 110i. ff

Thus this tends to frictionally hold the drawer in its locked position. When locking the drawer in its extreme dipen position;N
The intermediate keeper members act asy means for permitting the drawer to be heldpartially open in any preferred adjustedi position.,
The strength of the linger support 191er the..
ball will of course vary with the thicknessor temper of the metal used in making it and the casing, since it is of a continuous part ofthe casing. It can bedesignedoto support any. desired'` deiniteweight or pressure before,V spring-l ing, and at that yevent the giving or springing.- is` necessary to prevent rigidjbindi'ngv or sh0ck.

In Figure 7.1' haveshown a slightly modified form of `casing, which is generally indicated bythe cludes a cylindrical sidewall and a flat lower bottom Wall 26; which has struck-out therefrom the resilient inwardly directedt'ongue 2,7.` The tongue 2'71is connected" only at oneend tothe 19, and'thus forms al seat and means for nclnmally urging the ball bearing and'lockA toward' thebearing; strip or, plate 15., `The portior'is'v of. thebotto'mat opposite sides ofthe tongue-brace andthe.. ball Willenot. become, jammed in the casing.
