Complete Specification for the invention entitled AN IMPROVED CYLINDER LOCK.
The following statement is a full description of this invention including the best method of performing it known to me:- 1 ASC 49 1i nmrrI B IB -2- Device for fastening a rotary Lock cylinder The invention relates to a device for fastoning a rotary lock cylinder.
German Patent Specification 1,289,454 has made known a rose for cylinder locks which consists of solid material and which is countersunk in the door leaf and rests against the lock case on the inside. This rose does not offer sufficient protection because it can be grasped by means of a suitable tool and the rotary lock cylinder twisted off at its weakest point. The weakest point of this cylinder is in its centre, since underneath the keeper the profile is cut out for the passage of the keeper and the remaining cross-section is weakened still further as a result of the threaded bore for the guard screw.
German Offenlegungsschrift 2,609,647 proposes a reinforcing plate which is intended for protecting mortise locks with double cylinder-lock inserts and which is fitted into an inner clearance of the wooden door and is connected unreleasably to the Iock cover. This rotary lock cylinder too is fastened by means of a guard screw in a generally known way. A disadvantage here is that the plate would be very difficult to assemble and would offer inadequate protection against ways of breaking in by force. This rotary lock cylinder too is weakened as a result of the threaded bore for the guard screw. The guard screw is necessary here, because, by means of this, the cylinder is pulled against the edges of the cylinder cut-out in the lock case and the cylinder is thereby secured. In the case of a lock with a very long guard screw, the latter is inadequately guided in the Lock and does not secure the cylinder sufficiently, even when the guard screw is tightened very firmly. The cylinder is a -r °e o ElRST KLLER Tho Commissioner of Patents the alarge umbe of do n hi the lkandthe ARTHUR S,.o te a Stcan n a aofoln PATrNT AND TRAD NCAfT~SA JIVT" 9 YA.,CY.4 -3easily shifted by slamming the door shut or as a result of incorrect operation. If the cylinder has shifted, the keeper scrapes against the lock plate, and a large amount of force is then needed to rotate the key at all and to open the lock. The cylinder has to be recentered and adjusted again. As is known, there is a large number of doors in which the lock and the latch assembly with a long plate are not offset neatly and which, when the guard screw is tightened, can never be made to work smoothly.
The object on which the invention is based is to provide a device of the type mentioned in the introduction, which avoids these disadvantages and which nevertheless can be assembled and produced in a simple way.
The object on which the invention is based is, likewise, to provide a lock case and rotary lock cylinder which are particularly suitably for this device.
In one broad form the present invention provides a device for fastening a rotary lock cylinder inserted through a lock case, with a first hard-metal body surrounding the rotary lock cylinder on *he outside of the door, characterized in that the hard-metal body is supported on the lock case and is fastened to this and covers the rotary lock cylinder, at least in places, at the front also, in that means for the axial centering of the lock cylinder relative to the lock case are provided, and in that a second hard-metal body surrounding the inner portion of the rotary lock cylinder is arranged on the inside of the door.
Tests have shown that the first hard-metal body can project directly from the fittings and yet it is not possible to break it off. There is therefore no need for expensive long plates. Nor is there any need for a guard screw. The weakness of the rotary lock cylinder caused by this is avoided. Perfect and permanent centering of the rotary lock cylinder is nevertheless guaranteed. Pushing through or drilling out of the rotary lock cylinder are likewise largely forstalled.
The use of centering elements according to a preferred S' s8y/AMR S'4' 0 o. -4embodiment of the present invention allows continuous centering of the rotary lock cylinder in a simple way and on the other hand ensures that the latter is secured on the lock case in the axial direction.
The advantage of the mortise lock according to a preferred embodiment of the present invention is that rotary lock cylinders of differing profile can be used, thus simplifying stock-keeping substantially.
A further advantage of the device according to the invention is seen in the fact that the rotary lock cylinder no longer has to be coloured completely or in places, because it is covered completely or partially by the sleeve or sleeves.
An especially advantageous rotary lock cylinder with a Swiss profile emerges from another preferred embodiment of the present invention.
Exemplary embodiments of the invention are explained in detail below with reference to the drawing.
In the drawing: Figure la shows a part section through a door leaf with a mortise lock and a device according to the invention, Figure lb shows a part view in the direction of the arrow Figure 2 shows the device according to the invention, shown in Figure i, in an exploded representation, Figures 3 and 4 show two further alternative versions of the device according to the invention, likewise in an exploded representation, and Figure 5 shows a part view of a lock case, Figure 6 shows a third alternative version of a device according to the invention and a double lock cylinder in an exploded representation, Figure 7a shows a view of a basic body with inserted pins, and Figure 7b shows a vertical section along the line VII-VII in Figure 7.
Figure la shows a door leaf 24, into which a mortise lock

00: 0: Y 0. .0 f 0 trm~lr-ltaanr~lE~iil +Y 4a is inserted in a known way. Whilst the internal arrangement of this lock is designed in a known way, according to Figure the guard 50 differs in that there need be no passage hole for a guard screw underneath the both 53. A double rotary lock cylinder 1 is inserted into a passage hole 46. The shape of the passage hole 46 does not have to match the profile of the 01' Q8/AMR ,7 2 4.

a o rotary lock cylinder 1 exactly. On the contrary, the passage hole 46 is designed so that rotary lock cylinders of differing profile can be inserted. The rotary lock cylinder 1 possesses in a known way, between an outer cylinder part 3 and an inner cylinder part 4, a keeper 2, by means of which the bolt can be shifted in the lock case.
Attached onto the outer cylinder part 3 is a solid sleeve 8 preferably made of hardened steel. This has a clearance 52, into which is inserted a sleeve 13 likewise consisting of hardened steel. The sleeve 13 is rotatable in the clearance 52 and has a slot 13a and a bore 55 which are designed so that the cylinder part 3 can be inserted into the sleeve 13 with only slight play.
6. 15 The sleeve 8 has, at the front and immediately in front of the rotor 7a, a passage hole 12, into which a cover 14 made of hardened steel is inserted rotatably from the rear. This cover 14 is supported on the Lock case 45 by means of the sleeve 13 and has a slot 15, through which a flat key can be inserted. The sleeve 13 and the clearance 52 are designed so that the cylinder 1 is guided with only slight play over the entire length of the projecting part.
Two threaded pins 26 are screwed into the sLeeve 25 8, and these are inserted through passage holes 55 in the Lock case and has Csic] at the free end a thread, onto which a respective nut 27 is screwed. By means of the nuts 27, the sleeve 8 is pulled against the Lock case and fixed to it immovably. If the thickness of the lock case 45 is comparatively small, one or more shims 18 are 5 placed between the sleeve 8 and the lock case Furthermore, a pin 43 is pressed into the sleeve 8 at the top and engages into a bore 44 in the lock case 45 or into the shims 18. The pin 43, together with the screws 26 and the inserted rotary Lock cylinder 1, prevents the possibility that the sleeve 48 will be moved.
Attached on the inside of the door leaf 24 is a second sleeve 9 which likewise rests against the Lock 7_77;ii' i -6case 45, if appropriate with shims 18 interposed, and which covers the cylinder part 4 at the front, with the exception of an orifice 11. The sleeve 9 Likewise has a clearance 56 which corresponds to the form of the outer cylinder part 4 and in which this part is guided. Two blind bores 28 serve for receiving the nuts 27 or the pins 26. The sleeve 9 contributes to ensuring that the cylinder 1 is guided properly and that the sleeve 8 cannot be moved even if force is exerted. The bore 11 is usually not closed off by means of a cover, so that the key can be inserted directly into the rotor 7b here.
The rotary lock cylinder 1 can be centered in the axial direction at the time of assembly, so that the keeper 2 can be moved without jamming or scraping in the lock case 45. For this purpose, clamping elements 16 and 17 are inserted into the sleeves 8 and 9, rest against the bottom of the cylinder pouch 5 and engage by means of projections 57 and 58 into grooves 6a and 6b of the S, rotary lock cylinder 1. The clamping elements 16 and 17 20 have a continuous threaded bore, into which screws 19 and 20 are inserted. As a result of rotation of the screws 19 and 20, the rotary lock cylinder 1 can be shifted continuously in the axial direction. Orifices 35 and 42 in the sleeves 9 and 8 serve to ensure that the screws 25 20 and 19 can be operated after the sleeves have been attached. Once the rotary Lock cylinder 1 has been cen- Stered, a plug 41 and a screw 23 are inserted. The rotary lock cylinder 1 is now fixed immovably in the lock case S 30 Figures 3 and 4 show alternative versions of the 0* adjusting means by the example of a rotary Lock cylinder la and lb of so-called Swiss profile. The pouch 49 of the rotary lock cylinder la has a continuous steel screw 47 which projects with both ends. Sleeves 48 with a continuous threaded bore are screwed onto the screw 47. Cap screws 59 and 61 inserted through the sleeves 8 and 9 are, in turn, screwed into the sleeves 48 from the outside.

Sr rotary Lock cylinder la can be shifted continuously in one direction or the other. It is essentiaL that the cylinder pouch 49 be reinforced substantiaLLy by means of the screw 47. In the design according to Figure 4, sLeeves 64 are screwed onto a Likewise continuous screw 63 and are connected, in turn, to clamping eLements 49 by means of groove 65, 66 and pLug 67, 68. Screwed into the cLamping elements 49, in continuous threaded bores 57, are pins (not shown here), by means of which the cyLinder 1 can e centered and fixed, as mentioned above.
During assembly, the rotary Lock cylinder 1 is first inserted into the Lock case 45 and, if appropriate, shims 18 are put in pLace. The cLamping eLement 16 is 15 now inserted and the sLeeve 8, together with the inserted cover 14 and sLeeve 13, is attached. By means of the nuts 27, the sleeve 18 is secured to the Lock case 45.
The cLamping eLement 17 is now also placed on the cylinder part 4 and the sLeeve 9 is attached. The rotary Lock 20 cyLinder 1 is centered in the way described above, the hoLe 42 is closed by means of the plug 41, and the sLeeve 9 is fastened by means of the screw 23. The cylinders according to Figures 3 and 4 are assembled in the same way.
Here, however, there is the particular feature that the 25 bore 70 in the sleeve 13 corresponding to the position of the rotor is eccentric.
In the design illustrated in Figures 6 to 7b, the hard-metal body to be arranged on the inside of the door consists of a basic body 84 with a continuous cLearance 89, into which the inner portion of the rotary Lock cylinder 1 is inserted. The centering element 17 can be operated through this clearance 89. In addition to the clearance 89, arranged in the basic body 84 are four continuous bores 90, through which are inserted pins 35 screwed into the hard-metaL body 8 at the inner end. The pins 85 each rest by means of the wide head against a step 91 and puLL the hard-metaL body 8 and the basic body 84 firmly against the Lock case. The pins 85 each have

ew on- Cap are, -8on the head crossed sLots 81, into which are inserted in pairs crosspins 80 which prevent the possibility that the pins 85 wiLL come loose in an attempt at a break-in.
During assembly, the crosspins 80 are placed in halfdepth clearances 87 and are pushed into the slots 81 of the tightened pins 85 and subsequently bent at the free end into a niche 88. The slots 81 of the one pins are narrowed outwards, so that the crosspins 80 also cannot fall out in the axial direction of the pins Arranged underneath the cylinder pouch is a bar-shaped, stepped spacer element 82 which engages at each end into bores 83 in the hard-metal body 8 or basic body 84. This spacer element 82 is provided in those lock cases where the bodies 8 and 84 project beyond these at the bottom.
The spacer element 82 additionally stabilizes the two bodies 8 and 9 and ensures that, even in such lock cases, the bodies 8 and 9 cannot be moved and Loosened in any way relative to the lock case.
S: The basic body 84 is covered with a cover 92 20 which is fastened to the basic body 84 or to the lock cyLinder 1 by means of screws 26. Shims (not shown here) can be arranged between the cover 92 and the basic body S84.
The above particulars thus result in a device for fastening a rotary lock cylinder, which can be centered exactly without the use of a guard screw for the cylinders, and which guarantees easy operation of the rotary cylinder lock and prevents in an outstanding way even violent ways of breaking in, such as twisting off, ripping out and core- 30 pulling.
