LOCK

Filed April 8, .1926

WITNESSES INVENTOR WZZBauerZand ATTORNEYS Patented June 24, 1930 rE T MFEIF'EFCZE WILLI M TBAuEnnamx-or ELIZABETH, mnwannsnv LOCK Application fi16."Apri1 8,

This invention relates to' looks and particula'r'ly to lo'cksj for sliding closures, 'such as cages in banks.

lPrimarily the invention""comprehends a lock which is designed to' be gravitationally locked and electrically released although the" same is intended to broadly cover mechanical releasing means.

More speclfically, the lnvention contem- 19 plates a lock between the closure and closure frame in which an apertured bolt is carried by one of said members and in which a lock casing constituting a keeper is carried by the other of said members, said lock casing having an opening receiving the bolt, a locking element gravitationally projectable through the bolt aperture and means normally holding the gravitational locking element inactive and engageable by the bolt when projected into the lock casing for releasing the locking element to permit of its gravitational movement to a locking relation with the bolt aperture.

The invention aims as a still further object to provide'a lock of the character set forth which is comparatively simple in construction, inexpensive to -manufacture, and which is thoroughly reliable and highly efficient in its purpose.

lVith the above recited and other objects in view, reference is had to the following specification and accompanying drawings in which there is exhibited one example or embodiment of the invention which is in no of the appended claims as it is to be clearly understood that variations and modifications which properly fall within the scope of said claims maybe resorted to when found expedient.

In the drawings Figure 1 is a sectional view of the lock casing illustrating the bolt released;

Fig. 2 is a similar view illustrating the bolt inlocked relation;

Fig. 3 is a detail plan view of the bolt.

Referring to the drawings by characters of reference, A designates a portion of a sliding door or closure and B the doorway or closure frame.

The lock constituting the invention includes a bolt 10 having a ibase ll, which-as attached to theidoor or closure A, and which bolt is provided iwith a vertical apei tu'r'e l l2.

A 21001: casing V 1.3 is ise'cured tothe doorway or closure frame 113 and its 'front wall is :formed withiaFbolt reoeiving :opening 15.

' A horizontal "p artition 16 is arranged wit-him the -:'casing 213' between the upper'wal'l 17 and the lower wall 218, said :rpartiition being i-"substantially in" alinement with itheiupper edge ofthe :b6'lt IflVl'Ilg opening :15. aver-ti cally movable -'loc'liing el'ement l9 iis fde signed to normally desce'nd by gr-avity, through the partition 1 6', so that its lower end .lis received :irnf-fa "socket ior recessfiZO formed-in the lower wall *ofthe lock i'ca'singl flin or-der to maintain-theilo'cking ele ment" 19 in 'a raised position, 2a'supp0rt 2'1 is' provided .to' n'ormall y underlie "the lower end of athe locking element, said support beingnrnaintainedi-n positionilby a spring122 which surrounds the support stem23i-an'd is interposed between a spring-seat 24 the support: stem and one "of the pair "of "alums 25 of :a bracket 226 "which .is attached to ithe' underside of the partitionl-(i.

. din-operation, whenitheclosurezAlis moved tora 'closed 2 position, :the' bolt .10 is projected through the boltereceivirrg 'opening 15'where the :free end of the bolt encounters "the "support 21 and amoving the same "against the action of the spring 22, causes -the supp'ort element-to release the flocking element .19, allowing the. same @170 gravitationafly' drop casing, an inverted U-shaped bracket on the through the bolt opening 12 where its lower end is received in the socket 20. This efiectually locks the closure in its closed condition until the locking element is lifted. If the locking element is the core of a solenoid, as illustrated, when the'solenoid is energized the core or locking element 19 is raised so that when the closure A is opened and the bolt is removed from the casing, the spring 22will simultaneously effect the shifting 0f the support 21 to a normal r etaining position underlying the locking element or core 19.

As illustrated, the support element 21 is preferably formed of an inverted L-shaped piece so that the horizontal arm 28 thereof,

' which is of a lengthsubstantially equal to thedistance between the free end of the bolt 10' and the bolt opening 12, will serve to maintain the locking element 19 in a raised position until the bolt'opening 12 substantially underlies or intersects the path of movement of the locking element, thereby preventing friction and wear between the lower end of the locking element and the upper ,taceof the bolt 10. It is of course understood that the vertical depending arm 29 of the support is engaged by the nose or free end of the locking bolt when the closure is moved to a closed-position.

The invention is especially designed as a lock for cages in banking institutions'so that the tellers and clerks will be provided with a convenient means for locking and releasing the closures of the cages, it being obvious that the movement of the cage closure to a closed position will automati-' cally efiect its locking.

' Whatis claimed is: v

1. A lock comprising a bolt having a vering opening below the partition and a sock et in its lower wall, a bolt projectable into the casing and having a vertical aperture,

a solenoid vertically mounted inthe casing rgized, and a sliding and spring-pressed support mounted on the under side of the'parrtition and upon. which the core normally rests to maintain it in elevated position, said support being slidable from under thev aperture of the partition by the bolt whereby to permit of the gravitational locking engagement of said core with the bolt aperture and the casing socket when the solenoid is de-energized,
