' LEVER HOOK Filed April 30, 1932 Patented July 10, 1934 PATENT OFFICE 1 Claim.

The invention relates to improvement in door hooks. The old type generations old has never satisfactorily fastened a door. It has been impossible to pull the door into position by grasping the hook as no purchase could be had to pull it tight. In attempting to do this many minor accidents have happened such as laceration of the hands. Hence many doors such as rolling barn doors have been neglected and allowed to rattle and slam, also allowing rain and snow to get through the openings.

In the accompanying drawing forming part of this specification,

Figure l is a front elevation of my improved lever hook in applied position, and

Figure 2 is a cross section taken on the line 22 of Figure 1.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, 10 designates a door frame and 11 a door, these parts being of the usual and well known construction.

In carrying out the invention, I provide an elbow lever l which may be formed of strap metal. The long arm of the lever forms a grip or handle, while the short arm of the lever extends at an acute angle from the elbow of the lever with respect to the handle and is provided with a hook 2. The lever is pivotally mounted upon a wear plate 3 which is attached to the door frame by means of a screw 4 or similar connector. The lever is fulcrumed on a screw 5 or similar connector passed through the short arm of the lever between the elbow of the lever and the extreme end of the short arm. The screw 5 is passed through the wear plate 3 and into the door frame. A keeper 6, such as a staple or a screw eye, is secured to the door 11 to be engaged by'the bill of the hook 2. The handle of the lever 1 engages a stop screw or similar connector '7 when rocked to vertical position to hold the hook 2 01f center and firmly engaged in the keeper 6.

More specifically, the wear plate 3 may be an ordinary washer through the center hole of which is passed the securing screw 4. The fulcrum screw 5 of the elbow lever is disposed laterally of the screw 5 so that it will be particularly observed, the elbow of the lever extends over the screw 4 of the wear plate when the lever is in the operative full line position shown in Figure 1 and positively prevents loosening of the screw and wear plate. By virtue of the fulcrum 5 being disposed between the elbow of the lever and the extremity of the short arm thereof, said extremity will dispose the hook 2 oif center when in operative position so that pull of the keeper, due to the tendency of the door to open, upon the hook 2 will hold the handle of the lever l tightly against the stop 7 and positively prevent accidental dislodgment until the handle is manually rocked to released position.

Preferably, the extreme end of the short arm of the elbow lever is off set, as shown at 8 in Fig. 2, and is perforated to receive the abruptly bent end 9 of the hook, said end being terminally headed up, as shown at 12, to permit the hook to swivel freely. The offset end 8 of the lever permits of sufiicient clearance between said offset end and the door frame to prevent the hook from binding against the door frame when the lever 1 is manipulated.

When the lever is lifted the hook will reach out as much as two inches. The hook will engage staple or screweye. Then upon pressing down on the lever it will bring the door into position and close it so tightly that all of the old time annoyances are eliminated. As the lever descends it passes a centre, and locks itself into position by striking stop 7 as indicated.

The stock size of this device is lever 8 in. hook 4 in. but may be made in any size. It is also made in rights; and lefts to accommodate doors opening accordingly.

I clam:

The combination with a door and its jamb, of a staple carried by the door, a fiat washer on the jamb forming a wear plate, a securing screw passed through the center of the washer into the jamb, a substantially J-shaped elbow lever movable over the wear plate and having a long arm forming a handle and a short arm extending from the elbow at an angle to the handle and having its free end ofiset laterally to form a perforated seat at the rear of said short arm, a pivot pin independent of the washer securing screw passing through the short arm into the washer at one side of said washer securing screw, a latch hook adapted to engage the staple and having one end thereof bent laterally and extended through the perforation in the seat and provided with an enlarged terminal head fitting in said seat with the rear face of the head disposed in advance of the rear face of the elbow lever, and a stop pin disposed on the jamb and forming an abutment for the handle when said handle is in a vertical operative position.
