COMMUNITY TOOL STALL Y Filed oct. 1, 1941 5\ {sv 1,3 /5 f7 n ilk/ Patented Dec. 14, 1943 5 Claims.

This invention relates to community tool-stalls,

namely a stall for holding instruments which are same and which, upon an authorized removal,

retains a check upon the particular individual having the removed instrument in his or her possession. In accomplishing this end I. employ an assembly of paired locks of which the one is operated by a key carried by the community tool and of which the other is operated by any one of a plurality of differently identiiied keys supplied to the several persons authorized to use theY tool, and which assembly is characterized in that interconnection is had as between the two locks whereby the removal of a related key from its respective lock is possible only upon the insertion cf and retention of a key in the complementary lock. Stated more generally, I have provided a tool-stall in which a person authorized to remove the tool therefrom is required to insert his own key in the lock provided therefor and is thereafter precluded from withdrawing such key until the removed tool has been returned to and locked in the stall.

More particular objects and advantages, in addition to the above-stated general object, will appear in the course of the following description and claims, the invention consisting in the novel construction and in the adaptation and combination of parts illustrated in the accompanying drawing and hereinafter described and claimed.

In said drawing:

Figure 1 is a top plan view or a preferred ernbodiment of the invention having the cover plate broken away and showing some of the parts in horizontal section. Also indicated in'horizontal section in the View is the handle of a tool such as a vacuum cleaner Vhoused within the stall.

Fig. 2 is a somewhat similar view modied from Fig. l in that the users key has been inserted in the lock therefor to release the tool from its housed position.

Fig. 3 is a longitudinal vertical section on line 3 3 of Fig. 1 and indicating, for purposes of illuscasing 5 suitably secured by screws or the like 6 to the Wall 'l of a cabinet, with the casing being formed to provide an inner closed lock compartment 8 and an outer open-end stall compartment 9 which has aligned openings in the top and bottom walls to permit horizontal introduction of an upright tool handle, as T. Separating the two compartments is a partitioning Wall ill.

I3 represents a locking bolt bearing against the floor and one side Wall of the casing, and having its forward end projecting from the lock compartment through a suitable slide opening in the partitioning wall into the stall compartment, this bolt being formed along the exposed edge of its inner part with longitudinally spaced notches I4 and I5 and on its outer part having a terminal toe l5 which, by a sliding movement of the bolt in a forward direction, is caused to engage over a tool-keeper. I illustrate this tool-keeper as being produced in the manner of a bell-crank working through an approximate 90 movement about a vertical fulcrum l'l, one of its two lever-arms, as I8, being swingable into and from a position whereat the same is engaged by the bolt and the other arm I8 Ibeing swingable into and out of a tool-holding position traversing the throat of the stall.

Reverting to the lock compartment, it will be Seen that I have mounted two cylinder-type locks therein. The former of these locks is denoted by 20 and is carried by the cover plate 5 of the casing to occupy a vertical position and functions by the engagement of its reciprccative finger 2li in the rear notch l5 of the locking boit to slidably operate said bolt from a normal advanced keeperengaging position (Fig. l) to a retracted keeperreleasing position as indicated in Fig. 2. The actuating key Kv-l for said lock 2t is insertable in and removable from the cylinder slot while the nger 2l!" occupies its advanced position only.

Designated by 2l, the other of such locks ts through an opening in the partitioning wall lll and is mounted such that its key slot is exposed to the stall compartment and lies horizontally on the approximate longitudinal median line of the casing, whereas the reciprccative finger 2l lies within the lock compartment for movement from and into registering relation with the forward notch l 5 of the bolt, which registration is effected only upon a retraction of the bolt by the act of turning key K-l in the lock 2t. Benet-ed by K-Z is the key for the lock 2l, such key being removable only upona lodging of linger 2i in its related notch with a resulting locking of the retracted linger 20' against forward movement.

Key K-2 is carried by the tool, being formed with an extended shank 22 which is given a swivel mounting through the tool handle and having an exposed operating knob 23 tted on the opposite end.

It may be here stated as respects the locks which I employ, that the well-known characteristic which permits the related keys to -be inserted into and removed from the locks only when the latter occupy a specific rotary position is essential to the accomplishment of myend. It is also important that my locks be of that nature in which the rotary movement is limited to less than a complete turn in order that the lock shall, when the key is removed, be in the same condition as when the key was inserted. A lock of this type is illustrated by Yale in his U. S. Pat- No. 48,475. Y

The manner of using the stall is believed to be clear, a tenant whose key is identified by 4, for example, inserting the same in the lock 2) and turning the same to retract the bolt out of engagement with the keeper. The knob 23 is then turned counter-clockwise to lodge the finger 2| in the notch i5, clearing the tumblers of the lock and permitting the handle of the tool to be withdrawn from the stall. Being held against turning movement the user is prevented from clearing the tumblers of the lock 2li and withdrawing his key, whereie-r the identity of the user is known. Following a return of the tool with an insertion of key K-Z in the lock 2l andwithdrawal of the ringer 2l out of engagement with the bolt, key K-I may be turned to free the same, which movement again locks the tool within the stall.

It is believed to be apparent that the employment of other locks than the cylinder-type disclosed is well within the spirit of the invention, and it is thought equally apparent that other modications may be resorted to. It is accordingly my intention that no limitations be implied excepting as the same are necessarily brought into the hereto annexed claims to distinguish from prior knowledge in the art.

What I claim is:

l. In a community tool-stall, in combination: a casing providing a stall for the tool; a keeper carried by the casing and movable from -an inoperative position permitting insertion of the tool into the stall to an operating position barring removal of the inserted tool from the stall; a sliding bolt arranged to be moved from a position inoperative to the keeper into an operating position whereat, upon locating the keeper in the latters last-mentioned position, the bolt locks the keeper against movement; a lock supported by the casing, having a key-slot to receive a toolcarried key, and having a locking finger acting normally in the absence of the key to lock the bolt in its inoperative position and movable by the key out of engagement with the bolt for permitting the bolt to be moved into its keeper-locking position, said lock being formed with devices movable in relative correspondence with the movement of the nger and characterized in that the same permit the key to be inserted in and removed from the lock only when the finger is in said loclnng engagement with the bolt; and a second lock supported by the casing, arranged to be operated by a loose key, and having operative interconnection with the bolt for sliding the latter into and out of its keeper-locking position, said last-named lock being formed with devices arranged to move in relative correspondence withV the movement of said operative interconnection and characterized in that the same permit the key for such last-named lock to be inserted and removed from the lock only when the bolt has been moved into its keeper-locking position.
