COMBINED HOOK AND nour Andrew H. Hatchette, Cleveland, Ohio Application March 21, 1939, Serial No. 263,269
4 Claims. (01. 292 -105) This invention aims to provide a novel means whereby a hook may be held securely but releasably engaged with a keeper, it being a matter of common knowledge that a person desiring to crack his way into a house, generally can release a screen door hook from its keeper by shaking or pulling on the door, or by inserting athin, hook-lifting instrument between the doorand the door frame. I
Fig. l is an elevation wherein the bolt is retracted, Fig. 2 is an elevation wherein the bolt is advanced, Fig. 3 is an elevation showing a modification, the bolt being advanced, and Fig. 4 is an enlarged elevation 01 the spiral body of the hook, the showing of Fig. 4 applying, to either form oi. the invention.
The numeral I marks either a door or door jamb, carrying a screw-eye or other keeper 2. The numeral 3 designates a hook, made or a piece of rigid rod stock of common cross sectional diameter throughout its length, the hook includin a longitudinal shank 4 having at one end an eye I whereby the hook is pivotally connected to a screw eye or other anchor 8, adapted to be mounted (v 25 on either a door frame or a door.
the. hook 3 extends through the keeper 2 and has The bill of a side seat 8.
The intermediate portion of the shank 4 is formed into a spiral body 9, the terminal convolutions ID of which are closer together than are the remainingorintermediate convolutions. A bolt II is closely guided for right line reciprocation in the body 9 but is rotatable therein, the bolt having a lateral handle l2, movable between, and adapted to follow, the convolutions of the ody.
The operator lays hold 01' the handle-l2 and rotates the bolt II, the handle follows the con-'- volutions of the body 9, the bolt is advanced, the working end or the bolt cooperates with the seat 8, and the bill I oi'the hook cannot be disengaged from the keeper 2. When the handle I! reaches the less widely spaced convolutions l0 at the forward end of the body I, it is pinched between them, and it will not be possible, by shaking the door, to cause the handle I! to swing down, follow the convolutions of the body i and retract the bolt ll out of engagement with the seat 8. The less widely spaced eonvolutions II at the rear end of the body 9 function in the same way, to hold the bolt ii retracted.
In Fig, 3, parts hereinbefore described have been designated by numerals already used, with thesuiiixc. Thebodylalsshorter'thanthe body 9, and the bolt Ila has a shorter throw than the bolt II. Added security and stability in the bolt Ha are secured by mounting it in a depending guiding eye l4, produced by looping and twisting the shank 411 on itself, the guiding eye being disposed close to the bill la. Security ispromoted, moreover, because the working end. of the bolt I la engages not only with the seat to, but underneath and in contact with the keeper 2a, as well.
A smith or iron-master, who abides by what is claimed, may make changes in the precise structures shown, without departing in corresponding measure from the spirit of .the in v ention.
I claim: 4
'1. A two-piece retainer ior screen doors and similar closures, including a hook formed from rod stock and comprising a shank having a bill, the shank being spirally disposed to form a body, I:
and a bolt mounted in transverse handle, extended outwardly between the convolutions of the body and exposed there beyond for direct manipulation, the handle constituting means whereby-the bolt may be rotated, 1
the handle following the convolutions, when the bolt is rotated, thereby to advance the bolt longitudinally, into cooperating relation with respect to the hill.
2. A two-piece retainer for screen doors and similar closures, constructed as set forth in claim 1, and wherein the convolutions at one end of the body are located more closely together than are the other convolutions, and so closely together as to pinch the handle and hold the bolt releas ably against rotation and longitudinal movement.
' 3. A two-piece retainer -for screen doors and similar closures, constructed as set forth in claim 1, and wherein the convolutions which are at the inner end of the body are located more closely together than are the other convolutions, and so closely together as to pinch the handle and hold the bolt releasably against rotation and 10 8 close to theblll, the bolt being slidable in the guiding-eye.
