Description
Jan. 12, 1943. H. e. VOIGHT ADJUSTABLE CYLINDER LOG K Filed Oct. 31, 1941 Patented Jan. 12, 1943 UNITED STATES PATENT GFFICE' ADJUSTABLE GYLINDERLOCK Application October 31, 1941, Serial :No. 417,329
3 Claims.
This invention relates to looks, and more particularly to a lock in the form usually called a cylinder lock, and adapted to be inserted in an opening in the face of the door, and connected with a lock casing mounted in the door, usually by being mortised in an opening in the edge of the door. The lock housing carries mechanism adapted to cooperate with the mechanism of the lock casing, and therefore that part which is attached to the casing must be mounted in such a relation to the casing that there will be proper cooperation between the parts.
At the same time it is desirable that the outer face or cap of the lock structure be flush or substantially flush with the door itself or with an escutcheon applied to the face of the door.
In the usual form such cylinder locks are provided with athreaded portion adjacent their rear ends, which is threaded into the lock case, and the body of the cylinder lock itself is of such dimensions that it will extend through the face of the door and will not project outwardly to such an extent as to 'be unsightly. However, as doors vary in thickness, it is necessary to make the lock bodies or cylinders of different lengths, or to build up the escutcheon plate so that the lock will appear to be substantially flush therewith.
In the present invention these disadvantages are overcome by providing a two-part cylinder, one part of which is adapted to be secured to "the lock casing within the door, and the other part adapted to project to some extent from the face of the door, the parts being movably connected so that they may be adjusted for use with doors of varying thicknesses. It will be noted as the description proceeds that the two-part look body may be inserted through the usual opening in the face of the door, and the rear or auxiliary portion screwed into the case to such an extent as will enable the rollback to properly cooperate with the mechanism in the case, and the outer or main body portion of the lock may thereafter be moved inwardly by a longitudinal thrust so that the end face or cap will stand substantially flush with the face of the door or escutcheon plate thereon, and the parts of the lock will thereafter be retained in this position.
One object of the present invention is to provide a two-part lock body, the parts of which may be adjusted toward each other in order to vary the length of the structure to suit doors which vary in thickness.
A still further object of the invention is to provide a cylinder lock having a main body portion and an auxiliary portion, the auxiliary portion being adapted to be secured to a casing mounted within the door and being adjustable relatively to the main portion so that the length of the entire lock body may be varied.
A still further object of the invention is to provide a lock body'having a main portion and an auxiliary portion slidably connected with each other and having a one-way connection 'there'between, so that while an approaching "movement of the two portions of the lock body is freely permitted, the parts will be normally held against a separating movement.
Still another object of the invention is "the provision of a lock body having a main portion and an auxiliary portion arranged for sliding relative adjustment, and means providing a pawland-ratchet connection between said portions whereby adjustment between said portions in one direction only is normally permitted.
To these and other ends the invention consists in the novel features and combinations of parts to beherein'after described and claimed.
In the accompanying drawing:
Fig. '1 is a front elevationalview of a portion of a door upon which is mounted a lock embodying my invention;
Fig. 2 is a partial sectional view on line -2-2 of Fig. 1;
Fig. 3 is an elevational view of the lock body alone;
Fig. 41s a sectional view on line ii- 3 of Fig. 3;
, Fig. 5 is a sectional view on line 5-5 of Fig.3;
Fig. 6 is a sectional view on line 8-6 of Fig. 3; and
Fig. '7 is a sectional view on line 1-7 of Fig. 5.
To illustrate a preferred embodiment of my invention I have shown a portion of a door at Ill, in which is mounted a lock case ll of more or less usual form, the case as shown being mortised in the door through the edge thereof in the usual manner. Also mounted upon the door is an escutcheon I2 within which is mounted a socalled cylinder lock, designated generally by the numeral 13. Knobs M of usual form are also shown upon the door.
As shown in Figs. 3 to '7 of the drawing, the lock [3 comprises a two-part body, the rear or auxiliary portion of which is designated at 15 and the front or main portion at 15. The latter portion of the lock carries the end cap l'l,
and also has rotatably mounted therein the usual key barrel [3 and pin tumbler IQ, although it will be understood that the improvements are not necessarily limited to this particular type of lock.
The rear portion [5 of the lock is provided with screw threads '2'!) upon its exterior surface, adapted to be threadedly connected with the opening 2| provided therefor in the case I I. In this por tion of the lock is also mounted a rotatable hub 22 carrying a rollback 23 of more or less usual form, the hub 22 being held in place by the rollback and by a disk 24 secured at the face thereof opposite the rollback.
The hub 22 is connected to the key barrel 18 by means of a pair of pins 25, which as shown more particularly in Fig. 7, are secured in the hub 22 and have their ends slidably mounted in longitudinal openings 25 in the key barrel to provide for relative approaching and separating movements between the parts of the lock. As-
there are two of these pins, it will be seen that the hub 22 will be rotated with the key barrel when the latter is rotated by a key in the usual manner, in order to actuate the rollback 23.
The portion l6 of the lock is provided with laterally extending lugs 21 through which extend axially longitudinal openings 28, in which are slidably received pins or rods 29, the outer ends of which are secured to the portion l5, as shown at 3B. Thus the two portions of the lock body are attached to each other but are permitted relative longitudinal movements in the direction of the axis of the look by reason of the slidable connection of both sets of pins 29 and 25 in the main body portion Hi.
In order that the portions of thelock may be freely permitted a relative approaching movement but will be normally or releasably held against a separating movement, one or both of of this portion in the case.
the pins 29 may be provided with ratchet teeth 3|, with which cooperates a pawl member having means to engage the ratchet teeth to prevent movement in one direction, while in usual mannor of a pawl it will slide over the teeth when the parts are moved relatively in the other direction. As shown more particularly in Figs. 3 and 5, this pawl member is in the form of a plate 32 of dove-tailed form in cross section, which plate is slidably mounted in a slot 33 of corresponding shape in the body portion It. This plate is provided with openings 34 through which the pins 29 loosely pass, and adjacent the ratchet teeth 3| the edge portions of the openings are beveled, as shown at 35, so that these beveled edges will enter between the ratchet teeth 3| and normally prevent a separating movement of the two parts of the lock body.
It will be understood that the plate 32 is slidably mounted in the body portion it of the lock, and is normally urged in one direction by means of a curved plate spring 36 secured at one end to the lock portion is by the screw 31, and extending around the body portion l6 of the lock so that its free end lies over one end of the plate 32, as shown more especially in Fig. 4. The action of this spring will keep the beveled edge portions of the Openings 34, which act as pawls, in engagement with the ratchet teeth 3i.
On their lower sides, as shown in Fig. 3, one or both of the pins 29 may be provided with elongated recesses 39, leaving shoulders 49 ad jacent the ends of these pins. A set screw 4! is provided in one of the lugs 21, the end of which enters the slot 39, and while permitting free sliding movement of the pins 29 relative to the openings 28, will prevent the complete separation of the two parts of the lock by contact with the stop shoulder 49.
After the case H has been placed within the door and the bore formed therein to receive the lock I 3, the latter will be inserted in this bore, 75 l with the two portions l5 and IS in extended position. The parts, of course, may be separated by pressing inwardly on the free end of the pawl member 32 so as to move it out of engagement with the ratchet teeth 3| against the pressure of the spring 3%. When the pawl is out of engage ment with these teeth, the two sections or portions of the lock may be freely moved apart. The lock is then inserted in the bore provided therefor, and the portion I5 is threaded into the opening 2| in the case. A stop 42 may be provided on this portion of the lock to limit the insertion After it has been threaded in to the desired extent, the portion l6 of the lock is pushed inwardly until the end plate or cap I! strikes the escutcheon I2 or the outer face of the door if no escutcheon is provided. The outer portion of the case will then be held in position by means of the pawl-and-ratchet connection until the assembly is removed from the door by being unscrewed, at which time the parts may be separated, as already explained. The portion Id of the lock, it will be understood, is adapted to be secured in the case II in the manner usually provided, it being unnecessary to describe such mechanism in detail, as it may be of the usual form.
While I have shown and described a preferred embodiment of my invention, it will be understood that it is not to be limited to all the details shown but is capable of modification and variation within the principles of the invention and the scope of the claims.
What I claim is:
1. A look body comprising a main portion and an auxiliary portion, the latter being adapted for attachment to a casing, a connection between said portions comprising a pin secured in one thereof and slidably received in the other portion, and means normally preventing movement of said last-named portion in one direction on said pin, said means comprising a series of teeth on said pin and a spring-pressed pawl member slidably carried by the lock portion and engaged with said teeth.
2. A lock body comprising a main portionand an auxiliary portion, the latter being adapted for attachment to a casing, a connection between said portions comprising a pin secured in one thereof and slidably received in the other portion, and means normally preventing movement of said last-named portion in one direction on said pin, said means comprising a series of teeth on said pin and a pawl member carried by the lock portion, said pawl member comprising a plate-like member slidably mounted in the lock ortion and a spring urging a part of said plate into engagement with said teeth.
3. A look body comprising a main portion and an auxiliary portion, the latter being adapted for attachment to a casing, a connection between said portions comprising spaced pins secured in one thereof and slidably received in the other portion, means normally preventing movement of said last-named portion in one direction on said pins, said means comprising a series of teeth on the pins, and a plate-like member having openings therein to receive said pins, said member being mounted in said main portion for slidable movement transversely of the pins, and spring means urging said plate in a direction to engage the edges of theopenings with the teeth of the pins.
