UNITED STATES JOHN E. G. GETSEL, OF LEI-IIGHTON, PENNSYLYANIA.-

i I V l HASP 'rAs'rEivER.

Application filed March 6, 1923. Serial No. 3,225.

This invention relates to hasp fasteners, and particularly to improvements in hasp fasteners of the general type disclosed in my prior Patent No.1,096,902, dated May 14, 1914.

()ne object of the present invention is to provide, in combination with a hasp in the form of a hook, and a locking member which is supported by the keeper and adapted to engage a shoulder adjacent to the point of the hook after the point of the hook has been inserted through the keeper, means whereby the hasp or hook member may be positively held locked or against possibility of accidental disengagement from such looking member from vibrations or other causes.

A further object of the invention is to provide a structure which adapts the hook to be made in flat form, and to provide means whereby the pivoted end of the, hook may be pivotally mounted in such manner as to prevent it from swinging too freely or loosely, and whereby its hooked end may be properly guided for movement with relation to the keeper and locking member. 7

A further object of the invention is to provide, in such combination a novel construction of keeper member for supporting the locking member, guiding the hooked end of the hasp member into and out of engagement with the locking member, and which provides means for cooperation with the locking member or the hasp member for retaining the locking member in engagement with the hook member of the hasp member against possibility of casual displacement.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will hereinafter be more fully described and claimed, reference being had to the accompanying drawing, in which Figure 1 is a view in elevation of a liasp fastener constructed in accordance with my invention.

Figure 2 is a top plan view of aportion of'the hasp member thereof.

Figure 3 is a perspective view of the looking member.

Figure 1 is a top plan view of the keeper and locking member carried thereby.

Figure 5 is a top plan view of the pivot bracket.

Figure 6 is view similar to Figure 1' cf a modified form of heap struetnre withthe engaging hook 2 h ving a pointed I end 3 and alocking shoulder 1. y

The hook or hasp member 1 is made of flat metal and is pivotally supported at its opposite end by a pivot bracket 5. This bracket 5 is U-shaped and comprises an inner plate member 6 and an outer plate member 7 united at one end by the union connection 8. The other end' of this bracket is open to receive the pivoted end of the hasp 1 which entersbetween the plates 6 and 7. Adjacent to the union 8 the plates 6 are formed with openings 9 for the passage of a screw or fastening member 10, and adjacent to their free ends the plates are provided with openings 11 for the passage of a screw or other fastening 12. The fastening member 12 also passes through an opening in the end of the .hasp 1 and pivotally so- C1 "es the same to the bracket 5 andbetween the plate 6 and 7 thereof. Both fasteniugs 10 an; 12 may be employed tosegure the pivot bracket 5 to the surface to which it is to be attached and either one or both may serve as adjusting members whereby the platestl and 7 may be relatively adjusted to bind with greater or less force upon the pivoted end of the hasp 1. By this means the desired degree of freedom of pivotal motion of thehasp 1 may be secured and by the mode of mounting described the hasp 1 is pivoted to swing in a true path for proper guiding motion of itshooked end 2 into and out of engagement with the keeper and lockin member. 7

The keeper 13 comprises a Ushaped ele ment formed of parallel inner and outer plates 14 and 15 united at one end by a union 16, the opposite end of the keeper being open to receive the locking member 17. The plates 14 and 15 are provided witn alined pairs of registering openings to receive fastening screws or bolts 18 and 19, whereby the keeper may be fastened to the surface to which it is adapted to be secured. As shown, the locking member 17 is formed with a hole 20 to receive the screw 18, adapting said locking member to swing pivotally on the keeperby which i supported at all. 3;!

The lockin member is provided at one end with an engaging point 21 while the other end 21 of the locking member is relatively heavy so that the locking member will act by gravity to maintain an interlocked eugagement between the point thereof and the locking shoulder 4; of the hook.

lVhen the hook is removed from the keeper the pointed locking arm of the locking member swings upward, due to the greater weight of arm 11 of said locking member. lVhen the point of the hook is inserted down through the keeper, it presses downwardly against the pointed arm of the locking member, shifting the locking member from the dotted line position to the full line position shown in Figure 1, until the shoulder at passes below the pointed end of the locking member, whereupon the pointed end of the locking member engages said shoulder 4e and holds the hook of the hasp from withdrawal from the keeper. To release the hasp from the keeper, the weighted arm of the locking member is raised sufficiently to throw its pointed arm out of engagement with shoulder l, whereupon the hasp may be swung to released position.

In order to adapt the hasp member 1 to be positively engaged with the keeper member, so as to absolutely prevent separation of said members through any possibility of retraction of the locking member 17 by jolts, jars or vibrations under some conditions of service, I provide the hooked end of the hasp member 1 and the front plate portion of the keeper member 13 with eyes 22 and 23, respectively, which are adapted to register when the hasp member 1 is in applied position. Through these eyes 22 and 23 the hasp of a padlock or other auxiliary fastening member may be passed for a locking action to hold the member 1 secured to the member 13 against any possibility of separation from jolts, jars, vibrations or other causes liable to influence the locking member 17 and to cause its retraction.

It will be observed that with the construction above described a flat type of hasp mem her is provided which may be easily and economically manufactured, and in which provision is made for pivotally mounting it in such a way as to cause it to move in a guided path for accurate motion into and out of the keeper and into and out of engagement with the locking member in the acjustments of said hasp member. Further.

more, such pivotal mount-ing adapts the frictional engagement of the hasp member 1 with the pivot bracket 5 to be regulated as desired, to allow greater or less freedom of swinging motion of said hasp member. The described construction of the keeper member also provides for the convenient mounting of the locking member 17 and provision thereon of the eye 28 for cooperation with the coacting eye 22 provided on the hasp member. It will also be seen that the keeper plates, constructed and arranged as described, lie in front and rear of the pointed locking arm of the locking member and hooked end of the. hasp member, and therefore guide the same in their movements in a direct line, whereby any possibility of lateral pivotal motions of the keeper member and hasp member on their pivotal connections at such time as when they are moving into and out of connection will be avoided, ensuring their proper connection and obviating any liability of the binding of the parts on their pivotal connections and troubles incident thereto.

In the form of my invention shown in Figures 6 and 7 a hasp member 1'" is pro vided which has a hooked end 2 provided with a pointed terminal 3 and locking shoulder 4, as previously described, but which is pivotally mounted between its transverse center and hooked end on a pivotal support 24. This pivotal support 24- is shown in the present instance inthe form of a rivet car ried by a pivot bracket plate 25. This plate 25 is of rectangular form and provided at each of its four corners with openings 26 for the passage of fastening screws or the like to secure it to the surface to which it is to be attached. The hasp member 1 is hus provided with a short hooked arm 27 and a longer operating arm 28, of greater weight than the arm 27, the arm 28 being adapted to descend by gravity when the hooked arm 27 is released from the keeper to adapt the hasp to automatically assume a released position. An opening- 29 is provided in arm 28 to which operating means of any preferred character may be attached for actuating the hasp from any remote point. The keeper member 13 in this construction is substantially of the type heretofore described. as is the locking member 1'2", but a modified construction of means is here provided whereby, when the locking member 17 is set for engagement with the shoulder of the hasp 1*, said member may be held from accidental retraction. The means employed for this purpose comprises a pin'30 adapted to be fitted in an opening 31 in the weighted arm of the locking member to bear as '1st an abutment surface formed by the emved free end of the front plate of bracket 13, said pin holding the locking member against swinging movement in the: direction to disengage its pointed arm from the shoulder 4 of the hasp. When the parts are so locked the hooked end of the hasp member will be connected to the keeper member against any possibility of casual disengagement from shocks, jars or vibrations, but upon removing the pin from the opening 81 the locking member will be free for manual retraction in an obvious manner.

In Figure 8, I have shown a modified form of pivot bracket member which dispenses with the fastening screw and employs in lieu thereof an attaching screw 33 which is fixed to its inner plate 6, while in Figure 9, I have shown another form of pivot bracket 5 employing an inner plate 6 and an outer plate 7 having the openings 11 for reception of the fastening and pivot screw 12 but in which the use of the fastening screw 10 is dispensed with. In place of this fastening screw 10 the plate member '4' is provided with a fixed fastening screw 3% which projects through an opening in the plate 6 he screws 33 and 34L of the pivot bracket member shown in Figures 8 and 9 are adapted to enter the bore or other surface 36 to which the bracket member is to be attached, as will be readily understood. I desire it also to be understood that while I have described the devices shown in Figures 8 and 9 as bracket members, these devices may be used with equal efficiency as keeper members, in which case the locking member 17 will be mounted on a pivot pin,

bolt or screw passing through the openings 11 of such devices.

Having thus fully described my invention, I claim: 7

1. In a hasp fastener, a keeper of U- shaped formation and comprising a pair of spaced oblong front and rear rectangular plates arranged in parallel relation to each other and connected by a transverse union at one end, said keeper being open at the opposite end, a locking member having a' pointed arm and a weighted arm arranged at an angle thereto, said member being disposed between and pivotally connected at the intersection of its arms to the upper corner portions of said front and rear plates at the said open end of the keeper, and a pivoted hasp having a hooked end provided with a snoulder adapted to be engaged by the pointed arm of the locking member when said hooked end is inserted in the keeper, the said keeper plates being disposed in front and rear of the plane of motion of the hooked end of the hasp and of the pointed arm of the locking member therehetween and being of an eifective depth to bear thereon during the full ranges of locking and releasing engagements thereof and thereby, forming guides to ensure a direct line'motion of said parts and guards to prevent lateral rocking motions of the locking member and hasp on their pivotal connections while locked and during their engaging and releasing motions.

2. In a hasp fastener, a keeper of U- shaped formation and comprising a pair of spaced oblong rectangular plates connected by a transverse union at one end, said keeper being open at the opposite end,

a locking member having a pointed arm and a weighted arm arranged at an angle thereto, said member being disposed between and V pivotally connected at the angle of intersection of its arm to the upper corner portions of said front and rear plates at said open end of the keeper, a pivoted hasp having a hooked end adapted for movement between said plates and provided with a shoulder adapted to be engaged bythe pointed arm of the locking member when said hooked end is inserted in the keeper, said hasp being pivoted for movement of its hooked end in a single plane coinciding with and into and out of the space between the keeper plates for engagement with and disengagement from said pointed arm of the locking member, said plates being disposed in front and rear of the line of l1'lOVement of the pointed arm of the keeper and hooked end of the hasp for guiding the same in their movements and preventing lateral motion of the same on their pivotal connections, and means supplementary to the locking member whereby the hasp hook may be held from retraction in such single plane of motion when in engagement with the pointed end of the locking member.

3. In a hasp fastener, a keeper of U-- shaped formation and comprising a pair of spaced oblong rectangular plates connected by a transverse union at one end, said keeper being open at the opposite end, a locking member having a pointed arm and a weighted arm arranged at an angle there to, said member being pivotally connected at the angle of intersection of its arms to the upper corner portions of said plates at the open end of the keeper, a hasp having a hooked end provided with a shoulder adapted to be engaged by the pointed arm of the locking member when said hooked end is inserted in the keeper, said hasp being pivoted for movement of its hooked end in a single plane into and out of the space between the keeper plates for engagement with and disengagement from said pointed arm of the locking member, said plates being disposed in front and rear of the line of movement of the pointed arm of the keeper and hooked end of the hasp for guiding the same in their movements and preventing lateral motion of the same on their pivotal connections throughout the range of their locking and releasing movements, and a removable contact member on the weighted arm of the locking member adapted for abutting engagement with the keeper to hold said hasp from casual retraction when engaged with the locking member.

In testimony whereof I affix my signature. 7
