Patented Jan. 15, 1935 UNITED STATES PATE OFFICE I 1,988,185 v i e HASP noon Henry M. Borden; Minneapolis; Minn. Application April 5, 1934', Serial No. 719,132
I TClaims I g My invention relates to looks and more par- .5 the novel devices and combinations of devices hereinafterdescribed and defined in-the claims.
In the accompanying drawin which illustrates the invention, like characters indicate like parts throughout the several views.
Referringv to the drawing: Fig. 1 is a perspective view of the improved lock and hasp applied to a door and door frame respectively, said door and door frame being only fragmentarily illustrated;
Fig. 2 is a. view partly in elevation and partly in section taken on the line 22 of Fig. 1;
Fig. 3 is a viewpartly in elevation and partly in section taken on theline 33 of Fig. 2, and also showing parts of thelock mechanism in different positions by means of broken lines;
Fig. 4 is a perspective view of the back plate removed from the casing; I
Fig. 5 is a perspective view of the lock bolt and parts associated therewith;
Fig. 6 is afragmentaryperspective view of the lock casing; and I g 3 m Fig. 7 is a detail view in section taken on the line 7-7 of Fig. 3, on an enlarged scale.
The numeral 8 indicates adoor frame and the numeral 9 indicates a swinging door both of which are fragmentarilyillustrated. A hasp 10, of the type having a short leaf 11 connected to one end thereof by a hinge joint 12,-is attached to the door by screws 13 which extend'through holes in said leaf. When the hasp- 1.0..i'sc1osed it overlies-the screw 13 and prevents the same from being tampered with. The hasp 10 isoutwardly. oifset intermediate of its ends as indicated at 14, and formed in this offset portion 14 is an aperture 15 that is elongated longitudinally of the hasp 10.
. Referring now in detail to the improvedhasp lock, the same includes a casing 16 having an open back that is closed by a back plate 17. Formed with the casing 16, at the sides thereof, is a pair of diametrically opposite ears 18, the backs of which are inthe same plane with the open back of said casing. The back plate 17 is also provided. with a. pair ofears 19 that underlie the cars 18 and are rigidly secured thereto by rivets 20.
The casing 16 is secured to the door frame 8 by screw 16' that extend through aligned holes in theears 18 and 19. When the h-asp 10 is closed its offset port-ion 14 straddles the casing 16 and permitssaid haspto closely overlie the cars 18 and thus prevent the screws 16' -;from being tampered with. l 1
A segmental flange 21 detachably secured tothe back plate 17 extends into the casing 16: and closely follows the contour of the upper half of its internal wall. The right hand end of the flange 21 is bent substantially radially inwardly to afford a stop lug'22 and the left hand, end of said flange 21 is bent laterally outwardly to afforda' lock lug or abutment 23.
., As shown, the flange 21 is detachably secured to 'the back plate 1'2 by a plurality of circumferentially spaced lugs 21' formed therewith and which lugs loosely extend into apertures in said back plate. I
A heavy shortstud 2 1 extends transversely through the casing 16 and its outer end portion is journaled in the face plate of the casing 16. A I
The inner end portion of the stud 24 is materially reduced in diameter to form a trunnion that is journaled in the back plate 17. Rigidly secured v to the stud24 is a radially projecting arm-like carrier 25 arranged to be swung with said stud in the casing 16 about the axis of said stud. A lock bolt or. detent26 is mounted in along bore-like seat 27in thecarrier 25. This-seat 27 extends into the carrier 25 from'the outer end thereof on a radial line extendingfrom the axis of the stud 24. Formed with the lock-bolt 26 is a radial fin 28 that works in a groove 29 that extends through theoarrier 25 to the seat 27. Than -28 projects considerably rearwardly. of the rear end of the look-bolt; 2,6 andformed with its; rearend is an out-turned finger 30 arranged to beengagedby a key X and operated to retract the lock-bolt 26. I
A coiled spring 31, compressed between the stud 24 at the inner end of the seat 27 and the inne'r' end ofthe-lock-bolt 26; normally holds; said lock-bolt projected against theinner surface of the flange 21 except when projected under the lock lug. 23. The key-X, "which is only fragmentarilydllustrated; is guided into and outof the casing l6"by..the"openings 32 and '33 in'its face plate and the back plate 17. respectively. Said key X is further guided in the casing 16 and held while being turned by aslotted hub 34 turnably I mounted in the face plate of the casing 16 and the back plate 17.
Rigidly secured to the stud 24. outwardly of the turned transversely, of said aperture, as shownfi in Fig. 1, to hold the hasp 10 closed. The carrier 25 extends the full transverse width of the casing 16 with just a Working clearance therebetween and securely holds the stud 24 against endwise movement relative to said, casing.
When the T-head 35 is longitudinally aligned with the aperture 15 the lock-bolt 26 is in an upright position midway between the stop lug 22 and the lock lug 23. If the T-head 35 is turned to the left a one-quarter turn the lock-bolt 26 will engage the stop lug 22 and position said T- head transversely of the'aperture 15 and hold the hasp 10 closed. In this position of the lockbolt 26, the T-head 35 may be turned back into its original position to release the hasp 10 without the use of the key X. But if the T-head 35 is turned to the right a one-quarter turn'the lockbolt 26 will be moved past the respectiveend of the flange 21 and projected by the spring 31 under the lock lug 22. In this position of the lock-bolt 26 the T-head 35 is held transversely across the aperture 15 and holdsthe hasp 10 closed sothat it can not be released without the use of the key X to retract the lock- -bolt 26.
Just prior to the time the lock-bolt 26 is projected under the lock lug 23 the carrier 25 engages a' leaf spring 36anchored to the casing 16 at the side thereof and places said spring under tension. 4
Rigidly secured to the casing 16, just back of the spring 36, is a U-shaped member 37, one prong of which affords a stop 38 for the carrier25 during the final compression of the spring 36. The other prong 39 of the member 37 is notched to permit the key to pass the same during its movement to engage the finger 30 and retract the lock-bolt 26 to releasethe same from the lock lug 23. Or,
in other words, the notched prong 39 will only permit the proper key to be used in the lock. The purpose of the stopj38 is to prevent the carrier 25 from being turned hard enough to break the spring 36 and thereby permit the T-head 35 to be turned into longitudinal alignment with'the aperture 15 and permit the hasp 10 to be opened without the use of the key.
From the above description it is evident that by turning the T-head 35 to the left until stopped by its engagement with the stop ing 22, the same may be turned back to its original position to release said hasp without the use of a key. Or, on the other hand, if the T-head 35 is turned to the right until it passes the lock lug 23, the spring 31 will project the lock-bolt 26 under the lock lug 23 and thereby lock the T-head 35, in an operative position in which it can not be movedwithout the use of the key X.
From what has been said, it will be understood that the lock described is capable of modifications as to details of construction andjarrangement within the scope of the invention herein dis closed and claimed.
