HASP

Fild Aug. 1o, 19216 @Zh/meg.

Patented Aug. 29, 1950 invention relates to' .hasps designed for' usezwith vpadlocks` in' securing closures of various One 'ob'ject'of thel invention is to provide a hasphaving a; simpliedi form of. hinge pivot or` pintle" constructed. entirely from the material of thehas'p itself.

Another object kof the invention is to provide a hasp which affords anNunusnal measure of inthat the heads ot screws,A by which the parts are mounted are rendered substantially in accessible when the hasp is in locked position.

It is also an object of the invention to provide a hasp ofl unusual strength, having embossedreilnfcing' features-both. in the hinge member and iin-the. `'swinging haspv member attached thereto'.

Qther objectsand. advantages-.oi the invention will; appear-trom the followingifdescriptiontaken in connection with the drawings, in which:

Fig. 1 is a front elevational View of a hasp embodying this invention, showing in broken outline a padlock employed therewith.

Fig. 2 is a top plan view of the parts shown in Fig. 1, omitting the padlock.

Fig. 3 is a face view showing the hinge member of the hasp with a fragment of the hasp member in dotted outline, and showing also the staple and its mounting plate.

Fig. 4 is a fragmentary sectional view taken as indicated at line 4--4 on Fig. 1, and on a o larger scale.

Fig. 5 is a detail section taken as indicated at line 5-5 on Fig. 3, and on a larger scale.

Fig. 6 is a face view showing the two blanks from which the hasp and its hinge member are constructed prior to formation of the hinge connection.

The drawings show a hasp member I6 and the hinge plate I2 to which it is attached. Said hasp has a slot I4 adapted to fit over a staple I6 which is removably secured by a mounting plate I8. The hasp member I is hinged to the hinge plate I2, but instead of employing a separate pivot or pintle member, the material at one end of the plate Il) is curled or rolled upon itself at 2!! to form the hinge pivot. The hinge plate I2 is provided with a relatively broad tongue 24 extending from one end of the plate and adapted to be curled around the pivot portion 20, as shown in Fig. 2. The hasp member I0 is formed with a rectangular aperture 22 through which the end of the tongue 24 extends when thus curled around the pivot portion 20, and in which said tongue engages as the hasp member I0 is swung about the axis of its hinged 'CQnnection tothe plate I2..- v,Freierably.;,tvlle.

toi'fgue.V is formed with marginally rdisposed stiff-,.- eningfbeads 23-, and, preferably;V the plate` Iltis reinforced or stiiened by the formation of enr,- bossed ribs H1 extending longitudinally in the meiiriberA I0 at* the endsjof the aperture' y22',,and aligned with thefbeadsZQ` of thev tongue-24s 'ghe aperture 22 is shaped toziitaroundj the beads 23. s

Mostfhinges are designed to openby swingijlfigQ dicular to the plane of the plate l2.v As seen n- Fig. 3, this edge I3 is aligned with the-axisotthe hinge so that, as seen in Fig. 2 and Fig. 6, the tongue 24 extends from this edge and is thus somewhat shorter and stiffer than it would be if the plate were formed in accordance with standard hinge practice.

The staple member I6 is formed with a base portion 26 which is slidably secured in the channel 28 pressed outwardly in the plate I8. The top wall of the channel is formed with the slot 30, and the neck or reduced portion 32 of the staple I6 is accommodated in said slot with limi-l ted endwise play. The staple is provided with a shoulder 34 which faces the plate I6 in spaced relation thereto, and which may overlap the outer face of the hasp member I0 when the slot I4 of the latter is tted over the staple I6 in the posi-v tion shown in Figs. l and 2. The staple I6 is formed with a sloping nose 36 adjoining the shoulder 34, so that as the hasp member I is swung to locking position, the end of its slot I4 will engage this sloping surface 36 and cam the staple toward one limit of its sliding movement in the plate I8, this limiting position being indicated in broken outline in Fig. 2. Then, if del sired, the staple may be slid back to cause its shoulder 34 to overlap the plate I IJ, serving as a temporary means of retaining the plate in locking position. For many purposes thisA will be suicient, but for complete securement a padlock, such as that indicated at A in Fig. 1, may have its shackle inserted through the eve II of the staple I6.

Figs. 1 and 2 do not show the screws by which the hinge plate I2 and the staple plate I8 are secured in place, but it will be understood that the apertures I5 of the plate I2 and the apertures I9 of the plate I8 are provided to receive such securing screws. When the hasp member I0 is in locked position there is only a scant space between the under side of said member I0 and the outer surfaces of the plates I2 and I8; but to forestall removal of the hasp by manipulation of the securing screws, the plates I2 and I8 are formed with embossments so dimensioned that the heads of the screws are disposed entirely below the outer surfaces of such embossments, and are thus rendered inaccessible when the hasp member I0 is in locked position.

The plate I8 is formed with embossed portions 48 extending outwardly from the embossed channel 28 and each containing one of the apertures rims 44. The embossments 48 and 44 thus not only add material stiiness to the parts I2 and I8, but serve to protect the screws against removal when the hasp is locked. The reinforcing ribs II cooperate to oppose bending of the hasp member I0 in its locked position, and the extension of the plate I2 at the edgeV I3 stiffens the hinge tongues 24, as already explained.

While there is shown and described herein certainY structure embodying and illustrating the invention, it will be understood that the inven- In a staple construction for use with a pivot'- ally mounted, slotted hasp member, a staple to be engaged in the` slot of the hasp, and a mounting Vplate for the staple, said plate being provided with a generally medially disposed, upstanding, hollow rib, the u pper surface of which is slotted, said staple extending through said slot, said plate being normally overlapped by the hasp when the staple is engaged in the slot of the hasp, said mounting plate havingV embossments extending outwardly from said rib transversely of the plate on either side of the rib and adjacent opposite ends of the plate, each of said embossments being provided with a hole for an attachment screw, the material of said plate in said embossments and surrounding said holes being countersunk substantially to the plane of the plate to form head-receiving recesses in which the heads of securing screws will lie entirely below the upper surface of the embossments whereby said screw heads will be rendered substantially inaccessible when the hasp is in locked position onfthe staple,
