HOOK LOCK Filed Aug. 5, 1953 /fv VEA/T0@ /QEL 4. 9E/e 6.5/9/
5)/ Zim/777x Patented Oct. 30, 1934 UNITED STATES PATENT @FFICE 3 Claims.
My invention relates generally to locking devices and more particularly to a lock that is utilized for the purpose of locking hooks or eye bolts of the type that are utilized for securing window screens and screen doors in order to prevent the hooks from being released by means of wires or the like that are inserted through the screen of the window or doo-r.
A further object of my invention is to provide a hook lock of the character referred to that is relatively simple in construction, inexpensive of manufacture and capable of being easily and quickly applied to the hook or removed therefrom.
With the foregoing and other objects in view my invention consists in certain novel features of construction and arrangements of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:
Fig. l is a vertical section taken lengthwise through the body of the locking device and showing the hook engaging member in elevated position.
Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1 and showing the locking device applied to a conventional form of hook that is utilized for securing a window screen or screen door in closed position.
Fig. 3 is a sectional view of a Window sill, with the lower portions of the window sash and window screen frame and showing the locking device applied to the screen securing hook.
Fig. 4 is a top plan View of the locking device.
Fig. 5 is a perspective view of the key that is 'utilized for manipulating the hook engaging member of the lock.
Fig. 6 is a view showing elevations of the lower ends of various forms or" socket keys that may be utilized for manipulating the hook engaging member of the lock.
Referring by numerals to the accompanying drawing which illustrates a preferred embodinient of my invention, 10 designates the body or housing of the lock which is preferably tubular in form, permanently closed at its lower end and formed through the wall of this housing adjacent to the closed lower end, are diametrically opposite openings l1 for the reception of the end of the hook to which the locking device is applied.
In order to facilitate the placing of the locking device upon the hook the openings 12 are countersunk from the outside, as clearly illustrated in Fig. 2.
Secured to the upper end of the housing in any suitable manner, is a plate 12, preferably of metal in which is formed a non-circular opening 13 that is offset with respect to the center of the plate. As illustrated in Figs. l and 2 this plate may be secured to the housing l by bending the edge of 60 the plate downwardly and thence inwardly and the inwardly bent portion occupying a groove 14 that is formed in the outer face of the wall of body 10.
The intermediate portion of the inner face of G the housing is provided with a thread 15 for the reception of the externally threaded body of a locking pin or plug 16, the lower portion of which is tapered to form a conical point 17.
Formed integral with and projecting upwardly from the locking pin or plug 16, is a lug 18 that is non-circular in horizontal section. This lug is slightly offset or eccentric with respect to the axis of the pin or plug 16.
Formed through the wall of housing 10, just above the upper end of thread 15, is an aperture 19, which is for the purpose of permitting the ready escape of foreign matter such as dust or water that may enter the upper portion of the chamber Within the housing through the opening 30 13.
The key utilized for manipulating the locking pinvor plug 16, comprises a shank 20 provided at its upper end with a head 21 of any desired shape and carried by the lower end of the shank is a socket 22 shaped so as to receive the non-circular lug 18.
Ihe socket 22 may be ci any non-circular shape, for instance, any of the different shapes illustrated in Fig. 6, the only essential being that the socket is shaped so as to receive the noncircular lug 18.
In Fig. 2 I have shown a conventional form of hook H that is utilized for securing window screens and screen doors and the eye at one end of this hook engages an eye E that is seated in the frame of the window screen or in the screen door frame.
The free end of the hook H passes through an eye that is seated in the window or door frame and to lock the hook against disengagement from the eye through which it passes, the locking device is applied to that portion of the hook that projects beyond the eye as illustrated in Fig. 2 with the projecting end of the hooi: extending through the countersunk openings 1l.
Before applying the locking device to the hook, it will be understood that the locking pin or bolt 16 must be screwed upwardly within the housing by proper manipulation of the key in order that 11G the projecting end of the hook may pass through the openings in the lower portion of the housing and after the housing has been positioned on the projecting end of the hook, the key with its socket engaging the lug 18, is rotated, thereby screwing the pin or plug downwardly within the housing so that the pointed lower endthereof will engage and bite into the hookand thereby rmly secure the locking device to said hook.
When the locking pin or plug is screwed downward into engagement with the hook, the upper end of said pin or plug occupies a position just below the aperture 19 and thus any foreign substance such as dust or water may readily discharge from the chamber in the body above the pin or plug.
The opening 13 in the cover plate 12 is shaped to correspond with the socket of the key utilized in rotating the locking pin or plug and as this opening is offset or eccentric with respect to the center of the plate and the lug 18 is offset or eccentric with respect to the axis of the pin or plug, it will be practically impossible for a person on the outside of the window or door screen to insert a wire or the like through the screen and thence downwardly through the opening 13 to engage and manipulate the locking pin or plug.
1t will be understood that after the key has been utilized for screwing the locking pin or plug downwardly into engagement with the projecting portion Yof 'the hook that said key is removed. from the housing.
In some instances it may be found desirable to form a non-circular recess in the upper end yof the locking pin and which recess is adapted to receive the correspondingly shaped end portion of a key, such construction being merely a reversal of the arrangement herein illustrated and described.
Thus it will be seen that 1 have provided a hook lock that is relatively simple in construction, inexpensive of manufacture and very effective in performingV the functions for which it is intended.
It will be understood that minor changes n the size, form and construction of they various parts of my improved hook lock may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claims.
I claim as my invention:
1. A hool; lock comprising a housing provided in its lower portion with diametrioally opposite countersunk openings, a locking pin arranged within and having threaded engagement with said housing, the lower end of which pin is pointed, an eccentrically arranged non-circular lug projecting upwardly from the upper end of said locking `pin and the top of said housing provided with an eccentrically arranged noncircular opening.
2. A hook lock comprising a housing provided in its lower portion with diametrically opposite countersurik openings, a within and having threaded engagement with said'housing, the lower endof which pin is pointed, an eccentricaily arranged non-circular lug projecting upwardly from the upper. end of said locking pin, the top of said housing provided with an eccentrically arranged non-circular opening and there being a drain opening formed through the wall of said housing.
3. A hook lock, comprising a housing provided in its lower portion with diametrically opposite countersunlr openings and in its upper end with a non-circular opening that is eccentric with respect to the axis of the housing, a locking pin arranged within and having threaded engagement with said housing, the lower end of which pin is pointed, an eccentricaily arranged noncircular lug projecting upwardly from the upper end of said locking pin, which pin is operable by a key inserted through the non-circular opening in the top of said housing and the shape oi said non-circular lug corresponding with the shape of the opening in the' top of the housing.
