' 9"Qlaims. (01. 292-1) This invention relates to window :guard 100k! ing devices.
One object of the invention :is to :provide a lockingdevice of the character-described having improved .means whereby the-device retains a guard positively closed but in a releasable manner when .a window sash is opened, a :part .automatically preventing the deviceifrom being .released when'thesashpis closed. 1
Heretofore window guards have been held closed by key operated devices such as 'padlocks. In the event of fire it, was often'neoessary to find the .key, :which was sometimes mislaid, 'in order toopen the guard for-egress byway of fire escapes or othermeans. Compliance with the fire laws requires that the occupants .of a factory or. other building. must have the windows instantly available for-exit inv the event of hazard, and-this has been a source of frequent di'fiiculty-and-of violation of the law, due to :key locked window guards.
It is therefore an object 'of the. inventionto provide means for avoiding these .difficulties and at the same time to assure that the guards are locked when the factory is closed, without requiring any special-attention, andthat.'such:-*locking be accomplished in an effective and, reliable manner,
Another object of the invention'is the provision of an improved locking means which is released automatically on opening the window 'and. "is maintained in position. to positively non-releasably lock the guardon closing the window.
Since ventilation .requiresthat windows be fre. quentl opened, it is necessary to provide that this can be done without releasing the guard-and without requiring any particular manipulation for assuring that the guard is locked when the window is closed. It is of course the practice always to lock the windows in'closing up afactory V for the night, even Where guards are provided.
It is therefore another object of the invention to furnish improved locking means permitting a maximum range of free opening of thewindows, and .to cause'each of the guards to be locked at a plurality of remotely spaced points upon closing and locking the windows.
Another object is to furnish an improved looking device having a plurality of locking portions remotely spaced from each other for reliably closing a guard or other closure for a window, door, or the like, including an elongated member common to-both locking portions and positively removably locking one of them, together :with a supplemental locking element adjacent to the other locking portion for positively closing-the latter to thus cause the .elongated'member to be non-removabl held, and preferably to provide for :so mounting the elongated member in its released :position .as to maintain the first .mentioned locking portion inxpositively locked positionand whereby the said adjacent element can be. engaged without requiring manipulation of.
and arrangementsof parts hereinafter described in theirpreferred embodiments, .pointed out the subjoined claims, and illustrated in the annexed draWingsQWherein like .partsare designated by the same reference-characters throughout the several views.

Fig. 6 is a sectional view on line 66 of Fig. 5.
It will be obvious to those skilled in the art toin view, the invenwhich the invention appertains, that the same may be incorporated in several different constructions. The accompanying drawings, therefore, are submitted merely as showing a preferred exemplification of the invention.
Referring in detail to the drawings, denotes a device embodying the invention. The same may include a window frame having a lower sash l2 and an upper sash 3 slidable in the frame in the usual manner, these sashes having translucent or opaque panes and being maintained closed by any suitable means such as the conventional lock M. The same may include a base l5 fixed to the top of the lower sash and carrying a plate |6 eccentrically swiveled thereon at IT. This plate has an arcuate upraised camshaped flange l8 and a finger piece l9. On the lower rail of the upper sash is fixed a hook- 20 under which the cam element It; engages when the plate 5 is turned by the finger piece l9 to lock the window. In unlocked position, the plate I6 clears the hook 20 so that the window can be freely opened. This lock is shown open in Fig. 3 and closed in Fig. 4. For a reason hereinafter apparent, a guard element 2| such as a yoke or casing extends over the lock and is fastened to the lower sash, being open at the front for access to the finger piece and to permit the cam element It; to engage the hook 20. A modified protector 22 may consist of a rectangular box-like member secured to the guard 25 on the inner side thereof by spot welding to the guard or by yoke bolts 23 whereby the protector is adjustable along the vertical bars of the guard to set in the most desired relation to the lock l4. By interposing washers, the protector 22 may be placed as closely as feasible to the lock I4. Either or both of the protectors 2 I, 22 may be used, and they prevent the lock l4 from being opened through the spaces between the guard bars in the event that the window panes are broken. Since the locking of the guard itself is dependent upon maintaining the window closed, it is essential that suitable protection be accorded to the lock l4.
The guard 25 may be constructed of heavy wire mesh or of interconnected vertical and horizontal bars, the latter being shown for convenience of illustration. It may be substantially coextensive in size with the entire window and may comprise a rectangular marginal frame 26 hingedly connected at 21 to a side of the window frame to swing outwardly. A locking device for the guard 25 comprises a plurality of locking sections 30, 3| at the opposite side of the window frame adjacent to the top and bottom of the guard to securely lock the same. Each locking section includes a base member 32 consisting of one or more plates spot welded, riveted, bolted or otherwise secured to the guard. Each of these base members is provided with an eye, that for the top being designated as 33 and for the bottom as 34. Fixed on a portion 35 of the building wall are angles 36 suitably secured thereto. On these angles are rigidly mounted the strikes or jamb pieces 31 having openings 38 to receive the respective eyes 33, 34 with a suitable clearance. Common to the locking sections 30, 3| is a removable, elongated member or rod 40 having an upper end portion received in the eye 33. To the lower end of the rod is affixed a plate 4| having an opening 42 of sufiicient size to receive the eye 34 with ample clearance. The strike lies between the member 40 and the guard and may be conare perforated to receive the eyes 33, 34 only to carry the weight of the guard conjointly with the hinges 21. As thus far described, the member 40 may rest on the lower eye 34 to positively lock the upper lock section 30. To assure that the member 40 shall notslip on from the eye 34, the latter may be upwardly inclined or bent adjacent to its free end as at 43. To prevent release of the lower end of the member ,40 from ;.the eye 34, a hook45, having a portion of U-shapeinverted form is aflixed to a base such as an angle member 46 which is rigidly secured to the bottom portion of the lower sash |2. The sliding sash maintains the leading end portion 41 of the hook in alinement with the eye 34, whereby when the sash is moved to closing position the hook engages in said eye and prevents release of the lower part of the member 40. Thus the upper and lower locking sections 30, 3| are locked in a positive manner. Upon opening the lower sash, the hook 45 is disengaged from the eye 34 and the sash may be raised as far as desired.
In operation, the window may be opened for ventilation as desired. If the bottom sash I2 is opened, the hook 45 is raised, disengaging the lower eye 34 so that the lower locking section 3| is released. However, the upper locking section 30 remains positively locked so that the guard cannot accidentally open by pressure or otherwise. This locking of the upper section is maintained because the rod 40 is held in operative position by. its own inertia, resting on the lower eye 34, or retained bythe projections 43. If it is desired to open the guard, the rod 40 is merely slipped off the lower eye 34 and withdrawn from the upper eye 33, thus opening the upper locking section 30. No key operated locks are needed to open or close the guard. When the bottom sash is closed, the alined hook 45 engages the lower eye so that both sections 30, 3| are positively locked. Thi locking action may be consummated by closing the lock l4, the latter havin its associated protectors 2| or 22 or both, to prevent lifting of the lower sash by breaking the glass pane and manipulating the lock |4 through spaces between the guard bars. Of course, those spaces as in the case of woven wire may be too small for access to the lock I4, at least in the region adjacent to that lock.
