Application filed August To all w homer' may concern Be it lknown that I, REINHOLD -SCHOELL, acitiZen of the United States, and a resident of Stamford, inthe county of Fairiield and bte-te ot Connecticut, have inventedcertain new and Vuseful Improvements in Locks.; and l do hereby declare the following to be a full, clear,and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in locks, the object being to provide a rin dead lock with means that will so interlock with the keeper as to prevent a separation of the lock and keeper by jimmying or otherwise, sufficiently Ito release the bolt from the keeper, and it consists in a lock carrying a hasp adapted to engage a keeper and a bolt also engaging the keeper the hasp being `actuated by the movements of the bolt.
ln the laccompanying drawings; Figure 1 is a view in elevation oi a part of a door and jamb showing lthe 'lock and keeper in place and the "doon locked; Figure 2 is a view of the door from .the opposite sideV showing the cylinder lock; Figure 3 is a elevation and Figure 9 an'edge view ot the bolt; Figure 10. is aview of the hasp detached and Figure 11 is a view of the hzisp actuating lever.
The rim latch comprises a cover plate 11 adapted to be secured. to the inner side of a door. and a casing 12 secured to the cover plate in the usual and well known manner. Removably. .secured by screws 13 to the posts 1A, projecting from the inner surface of the casing 12, is the plate 15 provided adjacent itsV rear end with the support 16 to which the hasp operating lever 17, which will ybe hereinafter referred to, is pivoted at its 'rear end. The lever extends for- Specification of Letters Patent. Eat-@11159121 June 27 1922.

wardly-alongside of one edge'of the bolt 18, ivhich latter as shown in Figures 3 and il, is longer'than the usual :bolta'nd Vis mounted in and projects through 'both 'ends of the lock casing.l The vbolt is lprovided approximately atits Vcenter with a transverse slot 19 for the passage of the shank 20 of the knob. 21, and the shank' carries fthe 'arm 21a provided at its -outer free lend withlthe 4:hole to receive the .pin 22 on the slide block 23 which latter yrests and moves within the dovetailed igroo've 24 in `the :guide 25. This Vguidefis secured to the bolt adjacent one edge fof the latter, and projects `beyond said edge, andthe bloc'k 23 is provided with a wrist `pin 26 which connects it with the bolt actuating plate 27 which latter is engaged by the key mechanism hereinafter referred to. The'slide block is also connected tothe bolt actuating' plate v27A by the pin-22, which aspreviously explained also passes ythrough a hole in the endY 'of arm or roll-back 4cam 21a rigidly secured on the knob 'shank or spindle 20. It will therefore 'be ks'eenrthat the knob spindlev has 'a pivotal connection through -arrn' 21a with the Ybolt actuatingv plate 27, and the latter `is connected with the bolt through Athe medium of the 'slide lowers it to 'arposition in trent of said eXtension, the said bolt actuating :plate moving in the arc of a circle. Vhen in its retracted position it is at the rear of the yeXtension; 28and when inits projected' posifti'on as shown in Figure 3 it rests i-n Yfront of said extension and to retract the bo'lt the plate 27 must be moved upward-ly 'to fclear such extension, hence With this mechanism, the bolt will be deadlocked-in its two -po`sitions, and 'owing to the circular movement of the arm 24, the Ythrowof the bolt is apprezzi/mately twice the length of the varm 21 thus giving it an eXtra long throw.
Secured vto they outer face of bolt actuating `plate 27 the here@ Shoe shaped plate 27a, the open end of the latter being downward. Instead however of using` an eXtra plate, plate 27 can be thickened and recessed to form the U-shaped recess therein. This recess is to receive the pin 29 on the cover-roll-back-cam 30 which latter is turned by a key inserted in the cylinder or pin tumbler lock 31 at the outer side of the door.
This lock and its connection with the cover-roll-back-cam 30, is of the well known construction and operates in the usual and well known manner, so that when the cam 30 is turned by a key, the lug 29 thereon enters the open end of the recess in plate 27 and actuates the plate, by engagement with the walls of the U-shaped recess to shift the bolt. After the bolt has been shifted by the key mechanism, the continued movement of the key carries the cover-rollbackcam 30 down to the position shown in Figure 3 and out of the path of movement of the plate 27, thus leaving the latter free to be actuated by the knob 21 or by the key lock.
32 is a spring actuated lever pivotally secured to the bolt 18 in advance of the guide 25. This lever is of the bell-crank type and is connected at the end of its shorter arm to the spring 33, the other end of which latter is secured to and carried by the guide block 25, while the free end of the longer arm of said lever rests under the pin 26 on the sliding block 25 and above the free end of arm 21, and tends to complete the throw of the latter both in projecting and retracting` the bolt, so that after the pin 22 passes the centre, the tension of the spring acting on the lever throws arm 21 to its horizontal position even if the knob 21a be released bcfore the completion of the throw.
Tn the operation of the bolt by the knob from the inner side of the door, the arm 21 shifts the sliding block 23, which, acting against the guide 25 shifts the bolt. lVhen i the bolt is actuated by the key it is done through the engagement of the cover-rollback-cam 30 acting on the'plate 27. Tn both instances the bolt is shifted approximately twice the length of the lever arm 21 rollback-cam 30, that is to say, it shifts it from the positionV shown in Figure 4:, to that shown in Figure 3, consequently it gives to the bolt an extra long throw which with the hasp which will now be described will absolutely f prevent any separation of the keeper from the lock by jimmying or otherwise.
34.- is a hasp pivotally secured at its ends to the upper and lower edges of the lock ca se adjacent the front edge or face plate of the latter, and adapted when in its locking position to project beyond the lock and overilap the keeper. This hasp is secured to the pintles 35 and 36 journalled in the lock casand the pintle 36 terminates in a crank 37, the crank pin of which rests .int-he open front slot of the, hasp operating lever 17. This lever, as previously explained is located adjacent one edge of the bolt and the slot 17a therein receives the pin 38 carried by the bolt 18. The slot 17 a is straight for a point adjacent its front edge backward, and it then curves upwardly and slightly downwardly at its rear end as shown in Figure 5. When the bolt is projected as shown in Figures 3 and 5 the pin 88 rests adjacent the front end of the slot, and when retracted it rests at the rear end thereof. When the bolt is in its retracted position'the hasp is turned up and rests over the outer edge of the lock casing, as shown' in Figure 4L. As the bolt begins to moveoutwardly either by the actuation of the knob or a key, the pin 38 moving in the rear curved end of the slotshifts the lever in a direction to actuate crank 37 and throw the hasp overl to the front of the lock, as shown in Figures 3 and 5, and this movement of the hasp occurs before the bolt has been moved suliiciently to interfere with the movement of the hasp. By the time the bolt has been moved far enough for the pin 38 thereon to enter the suaight part of the slot 17a in the hasp actuating lever, the hasp will have been turned to its locking position so that the continued movement of the boltwill have no effect on it whatsoever. Tn retraction of the bolt, the pin 39 moving` in the straight part of the slot permits the bolt to be withdrawn sufficiently to free, or be out of the path of the hasp before the latter is turned back to itsI normal interlocking position, which turn ing movement effected by the pin 88 entering the curved. part of the slot 17a in the hasp actuating lever. From the above it will be seen that the hasp is turned to its locking position before the bolt is fully projectcd, and is not restored to its normal position until after the bolt has been partly retracted.
Tn the drawings T have shown a keeper 39 having two parallel strike plates 40 and 11, the latter being separated sufficiently to permit of the easy and free entrance of the hasp 34- between them. The second or outer strike 41 may be dispensed with, but l Vprefer to use it as it forms a housing forthe portion of the bolt projecting over the hasp.
Both strikes l0 and 4l are slotted to receive the bolt, and the slots are preferably somewhat larger than the bolt so as to provide for shrinkage of the door or jamb without any binding between the bolt and strike plate and the hasp is made longer than the strike plate for the same purpose. .The hasp is limited in its outward or locking movements by the pins-42 secured to the lock casing 12, and it is locked against any lost or free movement when in its normal or unlocking position hy the hasp locking pin e3. This pin 4,8 is mOllIlted to slide in the lock casing, with one rounded end projecting beyond the latter and its other end in engagement with the bolt 18, which latter is provided just at the rear of its free end with a groove 44 located in the plane ot the pin 43. The outer rounded projecting end of the pin'43 is adapted to enter the recess 45 in the inner face of the hasp when the bolt is retracted and positively lock the hasp against any swinging or lost motion. As the bolt begins its outward movement, the inner end of the hasp locking pin enters the groove 44 thus leaving the pin tree to'be moved outwardly by the hasp and the latter free to be turned by the hasp actuating lever 17 as previously explained.
ln the operation ot the lock, the hasp 34 is thrown to its position embracing the strike 40, before the bolt has passed through the latter and is in a plane below or at the rear of the bolt as the latter emerges from the strike 40 and approaches the strike 41, hence when the bolt is fully projected it is engaged by both strikes, and the hasp is within the keeper at the rear of the bolt and embracing the strike 40, and so secures the lock to the keeper that they cannot be forced apart by a jimmy or other tool, sufficiently to allow the bolt to be disengaged from the keeper, hence when the door is locked the lock can `be disengaged from the keepers only by the operation of the knob from the inside of the door or by a key from the outer side.
It is evident that many changes in the construction of the parts may be resorted to without departing from the spirit of my invention which comprehends broadly a hasp engaging a keeper for preventing a separation or' the lock and keeper and a bolt also engaging the keeper and overhanging the hasp, the latter being actuated to engage and disengage the keeper by the movement of the bolt.
