HENRY G. VOIGHT, OF NEW BRITAIN, CONNECTICUT, ASSIGNO'R TO RUSSELL & ERWIN MANUFACTURING COMPANY, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CONNECTICUT.

ADJUSTABLE CYLINDER-LOCK.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed February 15, 1908. Serial No. 416,039.

To all whom it may concern:

Be it known that I, HENRY G. VoiGHT, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Adjustable Cylinder-Locks, of which the following is a full, clear, and exact description.

My invention relates to improvements in cylinder locks, the object being to provide simple, effective and durable construction without sacrificing to quality, strength or durability.

Another object of the invention is to provide a simple and effective means for adjusting the lock whereby it can be connected to lock cases fitted to doors of different thicknesses.

In the accompanying drawing Figure 1 is a side elevation of the complete device, the parts being shown at approximately their minimum adjustment. Fig. 2 is a similar view, the parts being shown at approximately their maximum adjustment. Fig. 3 is a longitudinal vertical section of Fig. 1, certain parts being shown in section. Fig. 4 is a horizontal section of Fig. 2, certain parts being shown in elevation. Fig. 5 is a view of the inner end of the lock. Fig. 6 is a view of the outer end. Fig. 7 is a section on the plane of the line XX Fig. 3, looking to the left. Fig. 8 is a section on the same line, looking to the right. Fig. 9 is a view of a de ,tail of construction, showing the method of its connection.

1 is the face plate of disk-like form and constructed in any desired way, the said plate being provided if desired, with an ornamental scalp, as shown in Fig. 3.

2 is the cylinder casing.

3 is the plug.

4 is the pin tumbler casing.

The forward end of the cylinder casing 2 takes a circular seat in the face plate 1, while the forward end of the tumbler casing 4 has a rivet-like extension 5, whereby the parts may be secured against separation or independent rotation, thereby forming a frame of the parts 1, 2 and 4. The upper part of the tumbler casing 4 is preferably enlarged, as best seen in Fig. 8, while the lower part of the cylinder casing 2 is likewise enlarged. The external-wall of these enlarged portions is suitably shaped to receive thereon a hollow cylindrical shell 7, the inner wall of the shell being screw-threaded thereon, so that by turning said shell 7 relatively to the face plate 1 these parts will move toward or away from each other. The enlarged portions of the cylinder and tumbler casings constitute an effective support for the hollow shell, dispensing with the necessity of any guide pins or the like. The rear end of the hollow shell is provided with a closure or end plate 10, but in this form said end plate is preferably held against rotation therewith.

1717 are recesses in the opposite sides of the hollow shell 7 near the rear end. These recesses are formed by striking in the metal, so that they at once provide means to receive the end of a set screw carried by a lock case,

with which the cylinder lock may be connected, and also provide abutments or shoulders to support the end plate 10 at its inner side. The extremerear edge of the shell 7 may be curled over at one or more points, as shown at 7 a 7 a F ig.- 5, to hold the end plate 10 in place. 66 are bosses projecting laterally from the tumbler casing, said bosses being bored longitudinally to receive the dowel pins 1111, which are carried by the end plate 10. IVhen the parts are assembled, obviously these dowel pins 111l prevent the end plate 10 from turning independently of the face plate 1.

14 is a rollback rotatably mounted in the end plate 10. Projecting forwardlyfrom the hub of this roll-back are pins 1212, which make a telescopic engagement with the key plug 3.

3 is a cap at the inner end of the key plug to hold it in place.

15 is a bolt slidably mounted on the end plate 10 and adapted to be moved in and out to interlock with a locking shoulder 16 at the end of the hollow shell 7. When it is de sired to adjust the shell 7 on the frame, the bolt 15 is retracted, freeing the shell. The latter may then be turned freely until the desired adjustment has been secured. As the shell moves in and out, the dowel pins carried by the shell of the roll-back move in and out freely in their respective bores. When the desired adjustment has been effected, the bolt 15 is moved outwardly and may be locked in said position by a screw '18.

It should be understood that the terms roll-back and keyplug are conventionally employed and are intended to include the substitution of equivalent devices.

It should also be understood that the particular tumbler construction employed is immameans to permit the shell section to be rotated for adjustment on the frame section without disturbing the alinement of the plug and roll-back.

2. In a cylinder look, a frame, a rearwardly projecting threaded shell sup )ort, a hollow shell section havinga rotatablet 1readed connection with said threaded support and adapted to be adjusted to and. fro thereon by rotation, said shell section having a non-rotatable; back, a plug carried by the frame, a roll-back mounted on said shell back and adjustably connected with the plug, and means to lock the threaded connection of the a shell section against rotation relatively to the frame section.

3. In a cylinder look, a frame, a rearwardly projecting threaded shell support, a hollow shell section having a rotatable threaded connection with said. threaded support and adapted to beadjusted to and fro thereon by rotation, said shell section having a non-rotatable back, a plug carried by the frame, a roll-back mounted on said shell back and ad justably connected with the plug, and means to lock the threaded connection of the shell section against rotation relatively to the frame section, said locking means being carried by said. shell back and detachably en gaging said rotatable shell connection.

4. In a cylinder lock, a frame including a rearwardly extending threaded shell support, a hollow shell having a portion correspondingly threaded and rotatably mounted thereon, a plug in said frame, a rotatable roll-back and a non-rotatable support therefor, ad justable means of connection between said roll-back and plug and between said rollback, support and frame.

5. In a cylinder lock, a frame including a rearwardly extending threaded shell support, a hollow shell having a portion correspondingly threaded and rotatably mounted thereon, a plug in said frame, a rotatable roll-back and a non-rotatable support therefor, adjustable means of connection between said roll-back and plug and between said rollback, support and frame, said roll-back and support being connected with said hollow shell connection for movement to and fro therewith.
