To all whom it may concern: Y
Be it known that we, GEORGE L. BARNES? and JOHN L. CLOUGH, citizens of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and usefulImprovements in Door- Knob Locks, of which the following is a speciiication.
Our invention relates to door-knob locks, and has for its object to provide a door-knob with a locking device embraced within the door-knob, so that the knob is adapted to be attached to the` ordinary spindles in connection with ordinary door latches or locks, and may be used to operate such latches or locks to control the movements of the door or other deviceto which it may be applied; and to these ends our invention consists in the various features of construction and arrangement of parts, substantially as hereinafter more particularly pointed out.
Referring to the accompanying drawings, Figure l is a vertical section of a device embodying our invention. Fig. -2 is a transverse section on the line 2 2, Fig. 1. Fig. 3 is a section of a modified form of plunger, and Figs. 4, 5, 6, 7, and 8 are detail views.
The invention relates to door-knobs of the general character shown, described, and claimed in an application,Serial No. 501,572, and our present invention has for its object to provide a knob with akeyless locking de'- vice, which knob can be arranged to control any ordinary latch or other locking device, and can be readily connected to and is adapted to be used with the spindles vor other parts operating or controlling the locking or latching device.
The present invention consists, among other things, in providing the knob with a springactuated plunger controlling the clutch de.- vice, and in turn controlled by a series of locking-pins, which pins are controlled by a series of keyless locking devices, shown in the present instance in the form of pushbuttons, part of them being known as false locking devices.
It further consists in ,means for operating the plunger to detach the clutch devices, as well as in the special features of construction and arrangement ofthe various parts hereinafter more particularly pointed out.
It will be seen that Ythe clutch device may, be in operative engagement and the knob used as an ordinary door-knob, not requiring the manipulation of the keys to turn the latch or lock, or it may be set so that the latch or lock can only be turned when the proper keyless locking devices are operated in accordance with some plearranged relation ofthe parts, and it will also be seen that these relations may be varied or changed from time to time, and when the'proper keyless locking devices are operated the plunger will be automatically moved, so that the clutch will be engaged and the lockor latch can be turned; but when any of the false keyless locking devices are operated the plunger is prevented from moving and the lock or latch cannot be turned.
Referring to the drawings, B represents a spindle or connection or any ordinary or wellknown lock or latching device, which is adapted to be operated by the knob C when the parts of the knob are properly manipulated and the clutch or other equivalent debe of any shape or form or material, and, as shown, is `provided. with a shank or extension c3, which is provided with a ring or projection c4, fitting into a recess in the escutcheon D, which may be secured to the door-in the usual way, and which will hold the knob in place and permit its freely turning therein, and the spindle B in this instance is shown as attached to a block c5 fitting in the end of the shank c3 and embraced by the ring or projection c4. ,While this shows a convenient means of attaching the knob to the lock orlatch operating device, it is evident that any other Wellknown or equivalent means may be adopted. Some sort of a clutching device or connection betweenlthe knob and spindle must be provided, and While various forms of clutches the clutch. The knob is shown as recessed in its central portion and provided with a plunger G, comprising an enlarged. portion G which slides freely and a reduced portion G2,
or similar devices may be used we have vice isengaged therewith. The knob C may in the neck c3 of the knob, and the end of the reduced portion of the plunger is provided with one or more projections g, forming a clutch portion and arranged to engage with the clutch portion of thespindle when the plunger is in proper position. The plunger is normally under the stress of a spring G3, which in this instance is shown as fitting a reduced recess in the front hollowed portion of the knob, and bearing upon the plunger in a recess in the front end thereof, and tending to force the plunger so that the clutch devices will beengaged.
Surrounding the neck c3 is a collar F, which is connected to the reduced portion of the plunger by any suitable means, as by a screw fpassing through slots in the neck, and this collar is preferably fitted in the circular recess in the inner face of the knob adjacent to the neck, so that in its normal position it forms a practical continuation of the outline of the knob and adds to the symmetry of the device.
The movements of the plunger G are controlled by a series of keyless locking devices, which in the present instance are represented by the push-buttons Il Il', which are seated in the body of the knob and project radially therefrom, and part of these are so connected as to operate as false keyless locking devices and part as true keyless locking devices. These push-buttons are shown as normally under the stress of springs II, tend# ing to retain them in their outermost position, and are provided with spindles 71,', passing through openings from the recesses in which the push-buttons are mounted into the hollow space inside the knob. Some of these spindles, as of the true keyless locking devices, d0 not reach entirely through this passage, while others, as of the false keyless locking devices l-I, normally pass through the passages and their ends are practically iiush with the inner recess of the knob.
The plunger is provided with a series of radial recesses corresponding to the passages of the keyless locking devices, and in these recesses, or a portion thereof, are arranged pins I, which are free to slide therein and are shown as supported on springs I', which normally tend to press them outward. It Willbe seen that a portion of these pins, as those opposite the true keyless locking devices, nor Inally project a part Way into the passage of the push-button and operate to hold the plunger in its retracted or spring-pressed position, While others, as those opposite the false keyless operating devices l-I, yare normally flush with the periphery of the plunger, so that when the false push-button is pressed its spindle Will enter the corresponding recess in the plunger and prevent the plunger moving to engage the clutch device. It is not, however, absolutely necessary to utilize the pins and springs in connection with the false key less locking devices or push-buttons, as the recesses may be left open or free, as shown in some instances, Fig. 2, although it is considered preferable to provide the false push-buttons with pins and springs in order that they may assist in deceiving any one on account of the resistance oifered to the various pushi buttons, as they operate exactly in the same manner as the true keyless locking devices when the springs and pins are used.
In Fig. 2 We have 'indicated ve true keyless locking devices and the remainder are false locking devices, and it is evident that any desired number or relative arrangement of false and true lockingy devices may be adopted. It' will also be observed that the plunger is provided with a second series of recesses t', which, however, need not be provided With locking pins or springs, but serve simply to permit the keyless locking devices to be operated and forced in 'regardless as to whether the knob is locked or unlocked.
In Figs. 3, 4, and 5 We have illustrated another embodiment-of the plunger in which the stem G2 is extended and has attached to its outer end a plate G4, on which is mounted a ring-shaped piece G5, having openings or recesses in its periphery to receive the pins I. In order to provide these pins with spring-supports, we provide a crown-shaped spring K, which consists, essentially, of aringshaped piece 7c, having projecting arms 7.a', extending under the pins I and cach operating as a spring for the pin supported thereon. Some of these springs are normally bent, so as to maintain the outer ends of the pins flush with the periphery of the plunger, and some maintain them normally projecting beyond the periphery, asy shown in Fig. 3, the one being the true andtheotherthefalselockingdevices. VVheu the plunger is forced forward to engage the clutch,in this instance, the spindles ot' the push-buttons will pass by the face of the plate G4, the plunger moving forward sulficiently to allow this operation.
It is quite important that the keyless lock ing devices maybe depressed, both while the knob is locked or unlocked. Otherwise, if this Was not provided for, when the door or other device to which the knob is attached is left unlocked any one could discover the correct combination of the true and false locking devices, as the false push-buttons could not be depressed, their spindles bearing on the face of the plunger, and thus the combination Would become known; but by providing the additional recesses or arranging the plunger so that the push-buttons can be depressed under all conditions this feature is avoided.
While various forms of clutches may be used, We have shown in Fig. 6 a spindle having at one end one member of a clutch device, the spindle being adapted to be used in connection with the ordinary door lock or latch. Thus the spindle B has one end provided with the usual openings b or anyother Well-known construction for the reception and securing of the ordinary door-knob, and
IOO
IIO
the other end is provided with a block c5, which forms one portion of a clutch, and in the present instance is provided with pins b, arranged to engage similar pins on the plunger of the knob. The block also serves as a means of attaching the keyless knob, as before stated.
In Fig. 7 we have shown a modification of the plunger G, wherein it is recessed in its outer end, and mounted therein is another form of spring for the pins I, it being shown in this instance as having a center piece K',
adapted to be attached to the bottom of the recess and provided with a series of bent springarms k2, which are arranged and operate in a manner apparent upon inspection.
It will be seen that our invention can be applied to ordinary door locks and latches by simply removing the ordinary spindle and substituting the spindle shown, attaching the ordinary knob to one end in the usual way, and the keyless knob to the end having the block and portion of the clutch.
While we have described and illustrated the preferred embodiment of our invention and explained the principles thereof, it will be seen that the details of construction may be varied by those skilled in the art, and we do not therefore limit ourselves to the precise construction and arrangement shown.
We are aware of applications, Serial Nos. 501,571 and 501,572, tiled by George L. Barney as sole inventor, and We do not herein claim as joint inventors any of the broad features of the invention therein claimed as the invention of the said Barney.
