SPRING-LATCH D BOLT.

Patented sept. 9,` 1919.l

Application filed J une 20, 1918. Serial No. 240,902. i

To all whom 'it may concern.' i i Be it known that I, EDWARD W. `VVEILAND,

a citizen of the United States, residing at Fresno, in the county of Fresno and `State of California, have invented newand useful Improvements in Spring-Latches and Bolts, of which the following is a specification.

i The present invention relates to improvements in fasteners for windows, doors, and the like, and the object of the invention is to provide a spring` catch which can also be` used as a locking bolt to securely lock a window or door.

In the accompanying drawing, Figure 11s a side view of my improved fastener `in its locking position on a door or window; Fig. 2 is a horizontallsection on the line 22 of Fig. 1; Figs. 3, f1, are cross-sections on the lines 3-3-, 4:-4, looking in the directions of the arrows. e

Referring to the drawing, 1 indicates an edge of a door or window, and 2 a jamb therefor. Secured to saidedge by screws 3 are flanges 4 of a plate 6 forming the main portion of the casing of the bolt. The central portion of said plate is rounded in forni approximating a semi-cylinder. 7 indicates approximately semi-circular end plates secured to the main portion 6 of the casing by lugs 8 extending from said main portion through holes 9 in said semi-circular plates and being swaged or riveted thereagainst.

Through holes in said end plates can slide a bolt 11 which is for the most `part cylindrical in form, so that the hole in one of the end plates is circular to conform to the cylindrical form of the bolt at that end. The beveled or operating end of the bolt is formed on opposite sides with extensions 12 which, when the bolt acts as a spring catch, slide in correspondingly shaped extensions 13 of the hole at that end, which is otherwise circular. When the bolt is in its locking position the extensions 12 are outside the extension slots 13, and the `bolt can be turned, the hole 10 in the keeper 15 being elongated to permit the bolt to be so turned. These extensions are of such width that, when the bolt is turned from the unlocking position through a quarter turn into its locking position, as shown in dotted lines in Fig. f1, one of the extensions 12 engages the edge 20 of the keeper at the side toward which the door or window would swing when opened, and binds against said edge `and prevents rattling" of the door or window. Through saidbolt is screwed a screw 14 within a sleeve 16 forn'ling a linger piece andwhich can slide in a slotin the round portion of the casing, said slot having a lonfritudinally extending part 17 and acircunifercntially extending part` 18. The sleeve 16 serves to limit the movement ofthe screw into the bolt and also to reduce the friction due to the movement of the bolt in the slot. Around the bolt within the casing is a` washer 19, and between the washer and a washer 21 pressing against the outer end plate 7 is compressed a spring 22 coiled around the bolt.` `The inner ends of the extensions 12 normally, or when the device acts as aspring catch, abut against the washer 21 and prevent its outward movement on the bolt. The purpose ef the washer 19 is to prevent said spring fromn'loving into a position where parts of it might engage opposide sides of the sleeve 16. A spring23 coiled around the bolt isalso compressed between the sleeve 16 and the inner side of plate 7 of the casing.` The spring 22 is stronger than the sprinfv` 23, so as to prevent the bolt being pushed outi Yard by the spring 23 to a position, for instance, opposite to the part 1S' of the slot; but it will be observed that the spring 22 exerts no positive inward pressure on the bolt, since it presses at its ends on the washers 19 and 21, both of which act as if fixed on the bolt. The spring 22, however, is of such length and strength as to permit the bolt to be positively moved outwardly by hand so that it can be turned into the circumferential portion 18 of the slot, in which portion it is firmly held by the' pressure of the spring 22 pressing the sleeve 16 against the side of the slot.

It will be seen that while the spring 23 acts merely as a latch spring, the spring` 22 serves as a yielding resistance, preventing the bolt being moved outwardly too far by the spring 23, and also as a return spring, returnin the bolt to itsnormal position after it has een operated by hand.

The bolt is shown as arranged for a door or window swinging outward. lt can easily be reversed so as to be capable of being applied to one swinging inward by unscrewing the screw out of the bolt,rmoving the bolt outward a sulhcient distance to allow it to be turned through a half turn, and then again screwing the screw into the bolt. Thus the fastener can be used to secure any window sash, door, transom or the like, or in any place where a catch is desired, as the side, top or bottom orv center of a double Window.

By reversing the springs, the device no longer actsas a spring catch but is a locking bolt only.

At the rear end of thebolt is a notch 25 to enable the bolt to be turned by a rotatable instrument when too high to be reached by the hand. 24 indicates a finger piece for closing the door or Window.

I claim zy Y 1.V In combination with a keeper, a bolt casing, a bolt slidable therein and having a beveledl operating end, a spring normally pressing said boltoutwardly, a spring providing a yielding resistance-*to the movement of the bolt .due to the action of the first-named sprino', means whereby the bolt may be turned :bout a longitudinal axis, means for locking the bolt when so turned, and'means for normally preventing the bolt from being turned, but permitting it to be -turned when moved longitudinally against the second-named spring.

2. In combination with a keeper, a casing having a longitudinally extending slot, a bolt Vslidable in said casing and rotatable about a longitudinal axis therein and having a beveled locking end, a finger piece connected to thel bolt and movable 1n said slot, said slot sisting the outward movement of the bolt A that the linger piece is normally out of registry with the lateral extension in the slot.

. 3. In combination with a keeper, a bolt, a casing therefor having in its liront end an aperture through which the bolt can slide,

said aperture having a lateral extension, and.

the bolt having a lateral extension adapted to slide through the extension of' the aperture, said bolt extension being adapted when the bolt is turned about its longitudinal axis to press transversely against a side of the keeper, the casing having a longitudinal slot, a nger projecting from the bolt and slidable in said slot, said slot having a lateral extension, and the bolt extension heilig out of Said aperture extension when the iinger is adjacent, or opposite to said slot extension, a washer on the bolt adjacent to the front end of the casing, and spring coiled around the bolt between the linger and the rear end of the casing and the washer respectively.
