AUGUST TANNER, 0F BROOKFIELD, MISSOURI.
IVIORTISE-LOCK.
T 0 all whom it may concern:
Be it known that I, AUGUsT TANNER, a citizen of the United States, residing at Brookfield, in the county of Linn and State of Missouri, have invented new and useful Improvements in Mortise-Locks, of which the following is a specification.
This invention relates to locks, the main object of the present invention being to provide a secure lock which is as far as possible burglar proof and which hasthe parts thereof so constructed and arranged as to prevent an unauthorized person from tampering therewith by removing portions of the lock to gain access to other parts thereof.
A further object of the invention is to provide a combined latch and lock in connection with means independent of the key for holding the locking bolt against movement.
With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts hereinafter fully described, illustrated and claimed.
In the accompanying drawings: Figure 1 is an elevation of the lock looking from the outside of the door. Fig. 2 is an elevation of the lock looking from the inside of the door. Fig. 3 is a sectional plan view of the lock. Fig. 4C is an elevation of the lock with the adjacent face plate of the lock case removed. Fig. 5 is a detail sectional view of the bolt, showing the relation of the yoke thereto. Fig. 6 is a detail perspective view of the reversible lip or nose of the bolt. Fig. 7 is a similar view of the tumbler head or carrier and the tumblers carried thereby. Fig. 8 is a detail perspective view of the knob lock. Fig. 9 is a detail section through. the knob lock taken on the line 99 of Fig. 3.
The lock contemplated in this invention comprises a lock case 1 of suitable size to receive the lock mechanism hereinafter described, said lock case being provided at one end with a face plate 2 having an opening Specification of Letters Patent.
Application filed October 8, 1907.
Patented Get. 5, 1969.
Serial No. 396,460.
8 thereof toward either side of the lock, thus adapting the lock as a whole to be used either right hand or left hand.
The inner end of the bolt is recessed as shown at 9 to receive and admit of the movement of a bolt throwing arm 10 which projects from a yoke 11 which in the main is of the usual form, being provided with a squared hole 12 for the knob shank 13 so that when either of the knobs is turned the arm 10 operates to slide the bolt back and forth, the bolt being normally held outward in looking position by means of a two armed spring lat arranged in the inner lower corner of the lock case as shown in Fig. t, one arm of said spring bearing against a cam shoulder 15 on the yoke 11. The cam shoulder 15 is preferably provided with an antifricti0n roller 16 which bears directly against the spring 14: thus reducing the friction to a minimum.
17 designates a pair of fixed guide lugs within the lock case against which the sliding bolt 3 moves.
Arranged at the opposite side of the guide lugs 17 is a tumbler head or carrier 18 having a reduced shank 19 on opposite sides of which are arranged tumblers 20 all mounted on a common pivot 21 by which they are connected to the tumbler head or carrier. The tumbler head slides in a direction parallel with the movement of the bolt 3 between the lugs 17 and an oppositely arranged guide lug 22 while another stop lug 23 is provided with which the tumblers interlock as shown in Fig. a, the lug 23 also serving as a guide lug for the tumbler head 18. Two p'voted tiunblers 20 are shown on each side of the shank 19 of the tumbler head but the number of pivoted tumblers may be increased or diminished at will. Each tumbler is provided with a substantially semi-circular key-way 2% in which the bits of the key work and is also provided with shoulders 25 and 26 between which the stop lug 23 is received for holding the tumblers and preventing longitudinal movement of the tumbler head. Each tumbler is furthermore recessed in its upper portion as shown'at 27 and within such recess is arranged a tumbler depressing spring 28 which rides against one of the guide lugs 17 above referred to, said spring acting to hold the tumbler in engagement with the stop lug 28.
hen, by means of the key, the tumblers are moved out of engagement with the stop gether with the tumblers carried thereby must be shifted away from the knob spindle so as to disengage the tumbler head from the stop shoulder 29 after which the knobs may be turned to shiftthe bolt.
In the preferred embodiment of this invention,the knobs 30 and 31 at the outside of the door constitute short levers by projecting -wholly to one side of the axis of the knob spindle as clearly shown in Fig. 3, and in order to prevent-a person on the outside of the door from removing the usual screw 32 which fastens the hub 33 of the knob to the spindle 13, I employ a guard sleeve B iwhich slips over the spindle and entirely incloses and protects the screw 32 said sleeve being confined between the knob and lock case. The knob 31 at the inner side of the door is likewise provided with a hub 35 fastened to the knob spindle by means of the usual screw 36. The hub 35 is provided with a fixed collar 37 from which extends an arm 38 provided at its outer end with a sleeve 39 in which is slidably-fitted the plunger 40 of a knob lock having at its outer end a head or button 4-1 by meansof which it may be pushed inward or drawn outward. The plunger e0 isprovided in one side with a notch 42 which is engaged bythe lip or tooth 43 of a spring detent 44 secured to and carried by the arm 38, as shown in Fig. 9, the lip 43 being adapted to snap into the notch 42 to hold the plunger of the knob look when thrust inward. The escutcheon plate 45 at the inner side of the door is provided with a holeor socket to receive the inner end of the knob lock plunger 40; and it will now be seen that when the door is closed and the bolt in engagement with the keeper, by pushing the knob lock plunger inward, it interlocks with the es cutcheon plate at the inner side of the door and prevents'the knobs from being turned.
The keeper or striking plate 47 is composed of a piece of sheet metal secured to the door jamb or frame by ordinary wood screws, the greater number of which are covered by the door stop 48 which is applied to the door frame after the keeper is secured in place. The forward edge of the keeper is bent over or curved to one side as shown at 49 to facilitate cooperation with the lip or nose of the'bolt-in the 'actof closing the door. This also obviates the objectionable projection of the lip of the keeper now in common use and avoids catching the clothing thereon when passing hurriedly through the door.
In order to still further guard against fraudulent entry, reinforcing strips 50 of metal are secured to the door on theoutside and inside and adj acentto the'free edge of the door as shown in Figs. 1 and 2, and these strips are held in place by suitable fastenings, which, if in the form of screws, are preferably headed on the outside to prevent the removal of the outside strip by an unauthorized person. Theknob levers 30and 31 are arranged to turn away from the door jamb so as to avoid getting the fingers caught and hurt in opening and closing the door.
Having thus fully described the invention, what is'claimed as new is A look comprising a case, a sliding bo-lt, a knob spindle, a spindle hub provided with a bolt throwing arm, a radial shoulder projecting from said hub, a sliding tumbler head movable in a rectilinear pat-hat one sideof and parallel to the plane of movement of the bolt and shiftable'into and'out of interlocked engagement with the radial shoulder'on the spindle hub, a plurality of tumblers arranged at opposite sides-of said head and having a common pivotal connection with the same, individual springs carried by said tumblers and movable in sliding contact witha fixed surface, a projection on thespindle hub, and a flat spring bearing against said projection and operating toturn said hub'and throw the boltoutward.
In testimony whereof :I aflix my signature in presence of two witnesses.
AUGUST TANNER.
