HASP-LOCK.

Specification of Letters Patent.

Patented Oct. 30, 19.06.

Application filed May 15, 1905- Serial No. 260,485-

and capable of concealing the fastening de vices for securing it to a door and its jamb, sothat the lock cannot be removed surreptitiously without breaking it.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of a hasp-lock constructed in accordance with this'invention. Fig. 2 is a central longitudinal sectional view of the same. Fig. 3

is a sectional view on the line 33 of Fig. 2. Fig. 4 is a detail view, partly in section, illustrating the construction of the hasp and the keeper. Fig. 5 is a sectional view on the line 5 5 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a hinged hasp connected bya suitable hinge-joint 2 with a fixed section or leaf 3, which 'is secured by screws 4 or other suitable fasteningdevices to a doorjamb 5 and which lies beneath the hasp 1. when the latter is in its locked position, as clearly illustrated in Figs. 1' and 2 of the drawings. By this construction the screws 4, which secure the hasp to the jamb, are concealed by the hasp, so that the latter cannot when locked be removed without breakin it.

lhe hasp 1 is provided at its outer portion with openings 6, adapted to receive fixed lugs or members 7 and 8 of a plate 9, which is secured by screws .10 or other suitable fastening devices to a door 11. The plate and the fixed locking lugs or members 7 and 8 constitute a keeper, and the fixed members or lugs project beyond the hasp and are provided at opposite edges with notches 12 and 13, adapted to receive a movable locking plate or member 14 ofa detachable lock 15. The detachable lock 15 is provided with a substantially hemispherical casing 16, which is hollow and which is adapted to be placed onthe plate 9, which is circular and which is provided at its periphery with a projecting marginal flange 17, whereby a socket is formed for the lock-casing. The lock-casing is provided with a peripheral recess 18, receiving the marginal flange and forming a shoulder for engaging the same, as clearly illustrated in Fig. 2 of the drawings. By this construction the hasp-lock is provided with overlapped peripheral portions which prevent the introduction of a tool of sufiicient strength to break the look. When the lock-casing is in position, the screws 10 of the keeper arealso concealed, and the lock cannot be removed without breaking the same. This interlocking of the circular keeper and the circular lock-casing holds the 'parts against lateral of longitudinal movement on each other andprevents a tool from being introduced between them. The marginal flange 17 is provided with a recess 19 to receive the hasp 1 to permit the same to lie flat against the circular plate, and the lockcasing is correspondingly recessed at 20 to clear the has The movable locking plate or member is secured to an interiorly-arranged plate or bar 21 of the lock-casing by a pivot22, which pierces the plate or'bar and the locking plate or member and which is provided with a polygonal portion 23, adapted to be engaged by a key 24. The pivot 23 is arranged centrally of the lock-casing and the movable plate or member 14, and the ends of the latter extend into the notches 12 and 13 of the fixed lugs or members, as clearly indicated in Figs. 2 and 3, when the parts are locked. By this construction the lock-casing is firmly and securely fastened to the keeper. The cross-bar or plate 21, which is rigid with the lock-casing, is preferably formed integral with the same, and the said lock-casing may consist of a casting or be constructed in any other desired manner. The 'plate or cross-bar is provided with apertures 25, which receive the lugs and which register with the apertures of the hasp.

The lock-casing is provided at its center with a keyhole 26 to receive the key 24, which is provided at its inner end with a notch 27, whereby it is adapted to engage and rotate the rojecting portion of the pivot, which is rigid with the movable locking plate or member. Any other suitable means may be employed for engaging the inner end of the key with the movable locking plate or member, and the lock-casing may be provided with a rotary key-guide of the ordinary construction to reduce the size of a keyhole to a minimum and also to prevent the introduction of an instrument or a key other than that belonging to the lock. The locking plate or member is maintained in engagement with the fixed members of the keepers by means of a spring 28, secured at one end to the crossbar or plate of the lock-casing and having its other end engaging the movable locking plate or member at the outer side edge thereof. The spring is mounted on the said plate or cross-bar by means of studs 29 and 30, preferably formed integral with the said cross-bar or plate and arranged as shown. in Fig. 8; but any other suitable means may be employed for this purpose.

The lock-casing, which detachably engages the hasp and retains the latter in engagement with the fixed members of the keepers, is designed to be connected with the door by means of a chain 31, linked into an eye 32 of the lock-casing.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hasplock,' the combination with a hasp, of a keeper arranged to receive the hasp and provided with a plate, and a lock-casing detachably fitted on and interlocked with the plate of the keeper and also detachably engaging the hasp, said lock-casing being provided with interiorly-arranged means for engaging the keeper.

2. In a hasp-lock, the combination with a hasp, of a keeper receiving the hasp'and provided with a shallow socket, and a lock-casing fitted within the socket of the keeper and detachably engaging the hasp and provided with locking mechanism concealed within the lock-casing for rataining it in the socket of the keeper.

3. In a hasp-lock, the combination with a hasp, of a keeper provided with a projecting marginal flange forming a socket, and a lockcasing detachably engaging the hasp and provided with a marginal recess receiving the said flange, whereby the lock-easing and the keeper are interlocked, said lock-casing being also provided with interior locking mechanism for retaining it in engagement with the keeper.

4, In a hasp-lock, the combination with a hasp, of a keeper having a pair of fixed projecting members spaced apart and arranged to receive the hasp, a lock-casing provided with spaced openings to receive the project ing members and detachably engaging the hasp, and locking mechanism mounted with.-

in the casing between the said openings and engaging the projecting members.

5. In a hasp-lock, the combination with a hasp, of a keeper having fixed projecting members provided with opposite notches and engaging the hasp, a lock-casing detachably engaging the hasp and fitted on the keeper and concealing the fixed members, said lock-casing being provided with. an interiorly-arranged plate or portion having openings to receive the fixed members, and a movable locking-plate mounted on the said interiorly-arranged plate or portion of the lock-casing and detachably engaging the notches of the fixed members.

6. In a hasp-lock, the combination with a hasp having openings, of a keeper having fixed projecting members arranged to receive and engage the hasp, a lock-casing fitted on the keeper and having an interiorlyarranged plate or portion provided with openings receiving the said fixed members, a movable locking device arranged .on the said plate or portion and engaging the fixed members, and a pivot securing the movable locking device to the said plate or portion and projecting from the former and adapted to be operated by a key.

7. In a hasplock, the combination with a hasp, of a keeper provided with a pair of fixed projecting members having engaging portions located at the opposite edges of the members, a detachable lock-casing arranged on the keeper and detachably engaging the hasp, and locking mechanism concealed within the lock-casing and arranged to interlock with the engaging portions of the said members.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

CHARLES J. STREAMS.
