SPECIFICATION forming part of Letters Patent No. 469,946, dated March 1, 1892.
Application filed July 6, 1891. Serial No. 398.449, (No model.)
'12) aZZ whom it may concern:
' bined therewith; Fig. 2, a transverse section on line 06 or of Fig. 1, showing top view of the case; Fig. 3, a rear view of the handle-plate, showing rear view of the lock attached there- 'to; Fig. 4, a rear view with the lock in the position of being inserted through the opening in the plate; Fig. 5, a vertical section of the plate, cutting on line a: x of Fig. 4; Fig. 6, a modification showing transverse section of the plate and case as cast integral. Figs. 7, S, and 9 illustrate the arrangement of the lock in connection with the latch-case for variable thickness of doors.
This invention relates to an improvement in that class of cylinder-locks in which the cylinder is constructed with a longitudinal thin recess adapted to receive a flat key and in which the cylinder is arranged within a case, there being tumblers provided between the cylinder and case to interlock the two when in a certain position and so that by the insertion of the key in such position the tumblers will be thrown out of engagement and so as to permit the rotation of the cylinder within thecase. In this class of looks as usually constructed the lock is independent of the handle or knob plate of the doorthat is, the knob or handle plate with its connections with the latch are applied to thg door independent of the cylinder-lock, the construction requir ing'that the lock shall be located at some struction as hereinafter described, and particularly-recited in the claims.
A represents a knob-plate having an opening B through it, through which the knobspindle may pass, the plate itself forming the rose for the knob, the surface of the plate presenting an ornamental appearance. In case of a handle the handle is applied to the plate in the usual manner. So far as the attachment of the knob or latch-handle is concerned, the plate does not differ in construction or in means for attaching the plate from other plates too well known to require further description.
C represents the case of a cylinder-lock, having within it a cylinder D, adapted to rotate therein, the cylinder beingprovided with the usual flat key-hole E and the cylinder provided with tumblers 1 2 3, 850., which in the normal position of the cylinder are adapted to engage with the case so as to interlock the two and prevent the rotation of the cylinder, but yet so that when the key is inserted the tumblers will be moved to a position to disengage the cylinder from the tumblers and so as to permit the rotation of the cylinder, as usual in this class of locks. The arrangement of the tumblers or the mechanism between the cylinder and the case may be of any of the known constructions, such construction being immaterial to this invention.
As represented, the case is constructed with a face-plate F upon its outer end. The handle-plate is constructed with an opening G through it, corresponding in diameter substantially to the diameter of the case. The case is constructed with laterally-projecting 'ears H H, one or more, distant from the faceplate F corresponding to the thickness of the handle-plate, and the handle-plate is constructed with notches I from the opening G, through which the case passes, so that the said ears H Il may pass through the said notches I I, and then the case may be given a partial rotation to bring the ears H onto the rear surface of the plate, as represented, and
the cylinder then secured to the plate by means of screws J through the said cars, which positively secures the case of the lock tothe handle-plate as if made a part of that plate; or,
ICO
if preferred, the case may be cast integral with the face-plate, as represented in Fig. 6. I prefer, however, to make the case detachable from the handle-plate as a convenience for interchanging the looks with the plates, as occasion may require. By thus combining the lock directly with or as a part of the handle-plate the lock is brought within the space occupied by that plate and is readily applied to the door with the plate and secured to the door through the instrumentality of the plate instead of independent, as in the usual construction, it being understood that the plate A is secured to the door by bolts from the reverse side, as in the usual construction of such plates.
It will be understood that the radial projection L from the rear end of the cylinder forms the fingerby which the lock mechanism is engaged, and as usual in this class of locks. The cylinder being attached to or made as a permanent part of the plate, some compensation is necessary or desirable to adapt the lock to different thicknesses of door. To this end the latch-case is constructed so as to permit the rear end of the cylinder to pass into it to a greater or less extent. This construction is shown in Figs. 9, 10, and 11, a representing one side of the latch-case. Through this side of the case an opening I) is formed, corresponding to the shape of the cylinder or lock-case, and with a recess d therefrom corresponding to theradial projection L at the rear end of the cylinder, and so that the latch being introduced into a mortise in the door, as seen in Fig. 10, and the handle-plate applied the cylinder passes into the door and into the case to the required extent to engage the mechanism. In Fig. 10 the latch-case is represented as atthe extreme distance from the handle-plate and so that the projection L will work close upon the inside of the plate a of thelatch-case. In Fig. 11 the same parts are represented, but with the latch-case in a position nearer the handle-plate, so that the cylinder projects farther into the case, yetso length of the cylinder, the cylinder projecting into the latch-case to a greater extent the nearer the latch-case is brought to the handle-plate.
I am aware that cylinder-locks have been combined with the knob or handle plate of a door, the case of the lock being attached to or made a part of the said plate, and therefore do not claim, broadly, such construction.
I claim- 1. A door handle or knob plate, combined with a cylinder-lock, the handle-plate constructed with an opening through it corresponding to the case of the lock, the case constructed with a face-plate upon its outer end and with ears projecting laterally from the sides of the case, the handle-plate constructed with notches from the said opening corresponding to the ears on the case, and the case secured to the handle-plate, substantially as described.
2. The combination of a door handle-plate having a cylinder-lock attached to or made a part thereof, the cylinder of the said lock provided with a radial projection at its rear end, combined with a latch the case of which is constructed with an opening I) (1, corresponding in shape to the cylinder of the lock and the projection therefrom, substantially as described, and whereby the cylinder of the lock with the said projection may extend to a greater or less extent into the latch-case, accordingly as the said case is set nearer to or farther from the handle-plate.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
HENRY MORTON.
