Specification of Letters Patent.
Patented dan. 5, 1915.
Application filed May '7, 1914. Serial No. 836,880.
To all whom it may concern:
Be it known that l, J osnri-r F. DUEPNER, J r., a citizen of the United States of America, resident of the city of St. Louis, and State of Missouri, have invented certain new and useful Improvements in Hasp-Fasteners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this speciication.
My invention relates to a hasp fastener one of the objects being to produce a simple and inexpensive door fastener provided with a hasp and a latch member secured to said hasp.
Another object of the invention is to provide a hasp fastener having a latch member which is so concealed that it cannot be readily operated by. a person unfamiliar' with the operation of the hasp fastener.
Figure l is a front elevation of my hasp fastener showing it applied to a door. Fig. H is a top or plan View of the hasp fastener, the door and door post being shown in section. Fig. IH is a detail view of the hasp. Fig. IV is a detail view of the latch member. Fig. V is a horizontal section taken on line V-V, Fig. l'.
1 designates a staple or pivot member secured to a door Q, and 8 is a keeper secured to a door post 4.y
A hasp A, pivotally supported by the pivot member l, is provided with a slot 5 adapted to receive the keeper 3.
B designates a latch member pivoted to the hasp at 6.
Recesses are formed in the latch member B, near one of its ends, to produce a locking tongue 8 adapted to enter the keeper 8, the other end of the latch member being provided with a recess 9 for the reception of the pivot member l. The pivot pin7 supporting the latch member at 6, is located between the recess 9 and the locking tongue 8.
1i/"Vhen the parts occupy the positions shown in full lines Fig. I the locking tongue 8 is arranged within the keeper 8 to secure the hasp and latch member to said keeper, thus locking the door to the door post 4. The door may be unlocked by moving the latch member B to the position shown in dotted lines, Fig. l, thereby withdrawing the locking tongue 8 from the keeper.
A finger piece l2 formed at one end of the latch member extends beyond the free end of the hasp, said linger piece being turned backwardly as shown in Fig. Il to cover the end portion of the hasp. The body portion of the latch member, excepting the upper portion of the tongue 8, is concealed by the hasp A when the door fastener occupies its locked position.
A person familiar with the operation of the door fastener, may readily unlock the door by placing one finger under the finger piece 12 and then lifting the latch member B te the position shown in dotted lines Fig. l; but since the body of the latch member is concealed when the door is locked, a person unfamiliar with the operation of the device would not readily understand hoW to unlock the door.
rl`he latch member B is preferably an inexpensive punching formed of thin sheet metal and the locking tongue 8 formed of this thin metal, is materially reinforced by a. longitudinal rib 13, the latter being produced by pressing the metal as shown in Figs. IV and V. The recess 9 is formed in the latch member B to provide abutments l0 and l1 adapted to engage the pivot member 1. These abutments serve as stops for limiting the movement of the latch member B with respect to the hasp A, the object being to limit the relative movements of the hasp and latch member so that the latch member cannot occupy a position below the keeper 3 when the hasp is applied to the keeper. The first step in locking the door is to apply the hasp A to the keeper, and this can only be done when the latch member B is located directly above the keeper where its tongue 8 will readily enter the keeper.
I claim l. A door fastener comprising a keeper, a pivot member, a hasp pivotally supported by said pivot member, said hasp having an opening for the reception of said keeper, and a latch member pivoted to said hasp at a point between the ends of the latch member, one end of the latch member being provided with a. locking tongue adapted to enter said keeper and the other end of said latch member being provided with an abutment adapted to engage said pivot member.
2. A door fastener comprising a keeper,
a pivot member, a hasp pivotally supported metal forming said locking tongue being by said pivot member, a metallic latch mempressed to produce a longitudinal reinforcber pivoted to said hasp, said latch member ing'rib on said ton 1 being provided with recesses near one of JOSEPH F. DUEPNER, JR. 5 its ends for the reception of said keeper, a In the presence of locking tongue, adapted to enter said keeper, M. M. APGAR,
being formed between said recesses, and the A. J. MCCAULEY.
