The presentV invention relates to' an improvement in doors and locks therefor of the kind in which thelock is composed of a locking mechanism and a-bolt and bolt casing formed independentlyl thereof these components vbeing separately arrangedin bores formed in the door with their axes at right angles to each other, such bores communicating with one another at the crossing of their axes, at which point the bolt casing is provided with an opening. This has the advantage/off avoiding-the necessity of making a rectangular recess or chamber in the door for accommodating the lock, as simple, cylindrical bores sufce. It will be apparent that the term door as usedherein includes all devices adapted to be secured by a lock, for instance, doors proper, the lids of cases or trunks, drawers, etc.
The object of the present invention is to provide anextremely simple and inexpensive lock of the kind described above, in which the componentsA are heldin their operative positions only by the surrounding material of the door, that is, they do not require any inter-connection and require only relatively narrow bores, whi-ch can easily be made and do not weaken the structure' of the door to any considerable extent.
Attainment of this object encounters in the first place the difficulty of eiecting, in a simple manner, an operative connection between the lockingY mechanism and the boltby which the locking and unlocking movements of the key or other operating means are transmitted to the bolt, such coupling having naturally to be effected after the bolt casing and the bolt are put in place in the corresponding bore, so that the coupling must be eiected through the opening connecting the two bores and through the opening in the bolt casing.
According to the invention, this diiculty has been solved by employing for the operation of the bolt a tumbler which is so dimensioned, and is loosely coupled with the locking mechanism in such a manner, that it can be inserted, independently of such mechanism, with its nose projecting into the bolt casing, and thereafter, by mounting the locking mechanism proper, can be centered in its operative position.
The present invention also provides for an assembly as above described, a lock in which the tumbler is arranged slidably but non-rotatably upon or in a member of the locking mechanism serving as a centering means Such mechanism comprising means for centering the said member within the corresponding bore and means for operating the said member so as to operate the bolt.
2 The invention further includes the structural embodiment. of such lock, of which two examples are hereinafter describedwith reference to the accompanying drawings.
In the drawings:
Fig. 1 shows a door and lock according to theV invention, in longitudinal section through the centre of the bore accommodating the bolt casing,
Fig. 2 shows a cross-sectional view on the line II--II in Fig. 1,
Fig. 4 is a perspective yviewl partially in section showing a detail of a portion of the lock with the keyn position for operating the lock, yand Figs. 5 and 6 represent two sectional views taken atright angles to each other of a portion of a door having a lock to be operated by a handle.
As shown in Figs. 1 and 2, the door-I has two cylindrical bores 2 and 3 made therein, crossing each other at right angles and having mounted therein the respective components of the lock,
such bores communicating. with one another at the point of crossing.
The blind bore 2y extending` in the plane of the door. contains the cylindrical bolt casing 5, in which the bolt Ii is freely movable lengthwise andY which, at the point of connection. of the two bores, is. providedwith an opening l. At the' forward end, the bolt casing is somewhat'i'lared as indicated at 8 in Fig. l, the casing being secured in the bore 2, which has a depth somewhat exceeding the length of the casing, by a screw 9. passing through a hole in the bottom of the casing and entering the wood of the door, so that the ared end of the casing is firmly forced into the mouth of the bore.
The operation of the bolt to lock or unlock the door is effected by means of a tumbler I0 of which the nose II enters,l via the opening 1, a recess I2 in the bolt 6, and which is loosely mounted within a sleeve I3 made of bent sheet metal and having a longitudinal slit I4 through which passes the nose I I of the tumbler.
The sleeve I3, which rotatably ts the transverse bore 3 is extended on either side by a tubular member I5, also made of bent sheet metal, such members being introduced into the bore and comprising at their inner ends radially projecting lips I6 entering the slit I4 of the sleeve in such a manner as to couple the sleeve and the said members for angular movement in either direction. The outer ends of the said tubular members I5, of which latter at least one is movable lengthwise within the sleeve I3 for the purpose of adapting the lock to the thickness of the door, are provided with a series of axially directed projections I5" and also with a centering pin I5 for cooperation with a tubular key I8 provided with a correspondingly shaped axial projection I 8 as shown in Fig. 4 in operating the lock.
The sleeve I3 and therefore the axis of rotation of the tumbler are centred in the bore 3 by so-called rosettes, that is by iianged bushes II pushed on the tubular members I5 and secured to the door by screws, not shown in Fig. 2.
For mounting the lock, after the bolt casing containing the bolt has been inserted in the bore 3, the appropriately dimensioned tumbler I is separately inserted into the bore 3 and its nose is projected through the opening into the recess of the bolt. After this, the sleeve I3, in which there is inserted at one end a tubular member I5 having a bush I1 which is rotatable but not axially movable thereon, is pushed with the slit I4 over the nose of the tumbler III, so that the latter is engaged in the sleeve. The second tubular member I5, on which the second bush I'I has been previously arranged in a rotatable but not axially movable manner is then inserted with its lip I6 in the slit I4 of the sleeve, and is adjusted lengthwise, whereupon the bushes I'I are secured to the door by the screws.
The entire assembly is centred in the bore 3v by the sleeve I3, the tubular members I5 and the bushes I1, so that when rotating the sleeve from one or the other side of the lock by means of the key, the tumbler is caused to move the bolt outward or inwards.
Figs. 5 and 6 show a lock arranged to be operated by a handle. The tumbler 2|, which again is so dimensioned that it can be inserted separately through the bore 3 into the recess of the bolt I6, is centred by a non-circular, for instance square, rod 22, which is pushed from one end through a correspondingly shaped hole in the tumbler and carries a handle 23 (Fig. 6).
The second handle 24 is secured to the rod 22 with the aid of a long screw 26 passing axially through the neck portion of the handle 24, and screwed into a threaded hole 25 in the rod 22 after the handle has been partially pushed on to the ing the rod 22 and pushing on the second handle 24, the bushes II are secured to the door by screws 2'I for the purpose of centering the assembly in the bore 3.
In this embodiment the bolt 6, which is provided in the usual manner with a bevelled end, is acted upon by a pressure spring, so that the lock operates as an ordinary self-locking snaplock.
What I claim is:
1. A lock comprising a sleeve to be applied in a bore of a door and extending at right angles to the plane of said door, a tumbler associated with said sleeve and having a single tooth, a cylindrical bolt casing to be applied in a second bore of said door extending at right angles to said rst bore and communicating therewith adjacent the crossing point, said bolt casing having an opening therein arranged to coincide with said crossing point, when the lock is in position in the door, a bolt slidably movable in said bolt casing having a recess formed in said bolt in position for the tooth of said tumbler to permanently engage said recess through said opening when the lock is in position, said sleeve having a lengthwise extending slit therein for accommodating the tooth of said tumbler and at least one tubular member secured to the sleeve, means for rotatably centering said sleeve in said rst- -A mentioned bore, and means for rotating said" sleeve through the medium of a key.
2. A lock according to claim 1 in which a second sheet metal sleeve is introduced in said first sleeve at least at one end thereof and havinga radial protuberance engaging the slit of said iirstmentioned sleeve, the free end of said second sleeve being arranged for. cooperation with a key for rotating said second sleeve and thereby said JACOB PETRUS BEELAERTS VAN BLOKLAND.
