HASP-MOUNTING.

Specification of Letters Patent.

Patented June 26, 1917.

To all whom it may concern:

Be it known that we, WILLIAM C. MARTI- NEAU and CLARENCE R. MARTINEAU, citizens residing at Albany, county of Albany, and State of New York, have invented certain new and useful Improvements in Hasp-Mountings, of which the following is a specification.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification.

Our invention relates to hasp-mountings locking devices, and is particularly adapted for the locking dedoors of railway cars for various kinds of vices of the sliding and the like.

As an example of one form of locking device to which the invention is applicable, reference may be had to U. S. Letters Patent No. 1,149,205, granted to us August 10, 1915.

The principal object of our invention is to provide a strong and durable mounting for the hasp of a locking device, to prevent the escape of the hasp from its pivot, and to reinforce the pivot to better resist the endthrust of the hasp.

Other objects will appear in connection with the following description.

Figure 1 of the drawings is a plan view of a hasp-mounting embodying our invention.

Fig. 2 is a central vertical longitudinal section of the same taken on the broken line 2-2 in Fig. 1.

Fig. 3 is a side view of the staple-form keeper.

Referring to the drawings wherein the invention is shown in preferred form, 1, is a hasp having at its inner end a pivot-eye, 2. The outer end of the hasp may be provided with the usual aperture, 3, for the bolt or staple of the complementary member of the locking device, not shown.

The hasp, 1, is pivotally mounted upon a supporting-plate, 4, which is provided with bolt-apertures, 5, whereby the plate can be attached to a sliding door or the like.

The plate 4, is preferably made of malleable cast-iron, and has cast integral therewith two tubular bosses, 67, arranged longitudinally of the plate.

The boss, 6, passes through the pivot-eye,

' 2, of the hasp, and forms the pivot for the hasp.

To prevent the escape of the hasp from its pivot, and to reinforce its pivotal connection with the plate, 4, we employ a keeper, 8, in the form of a staple, one leg 9, of the keeper being inserted through the tubular boss, 6, and its other leg 10, inserted through the tubular boss, 7, with the body of the keeper extending over part of the pivot-eye 2, of the hasp.

The ends of the legs, 9 and 10, of the keeper are upset or riveted upon the under side of the supporting-plate, 4, as shown at 11, in Fig. 2, whereby the keeper is rigidly secured to the plate. 1

The pivot-eye, 2, of the hasp is formed with suflicient lost-motion to permit the nelghboring end of the hasp to abut against the boss 7, which is outside of the eye of the hasp.

The end-thrust of the hasp in the direction of the boss, 7, is thus resisted by both bosses, 6 and 7, as will be seen from Fig. 2.

By having one leg of the staple-form keeper, 8, inserted through the boss, 6, and its other leg secured in rigid relationship to the plate, 4, at a point outside of the pivot-eye, 2, of the hasp, the keeper not only serves to prevent the escape of the hasp from its pivotal connection, but reinforces the pivotal connection formed by the boss, 6, and serves to transmit part of the stress upon the pivot-boss 6, through the leg, 10, of the keeper to the plate, 4, at a point more or less distant from the pivotboss, 6.

By means of the boss, 7, the plate, 4, is reinforced at its point of connection with the leg, 10, of the keeper, and the stress transmitted through the leg, 10, is better distributed to the plate, 4.

The eye-portion of the hasp is preferably made of such cross-sectional form that it engages the respective bosses, 6 and 7, at points immediately adjacent to the surface of the plate, 4.

The body, 8, of the keeper is necessarily located at a certain distance from the surface of the plate, 4, sufiicient to permit the hasp to be swung freely upon the keeper in all directions.

We find it desirable to make the dimen sions of the eye of the hasp at th inner end of the hasp, such that, when the hasp is in locked position, said eye-portion will have practically only the same clearance with respect to the body, 8, of the keeper, as it has in its swinging movements This result we are able to accomplish, while preventing the eye-portion of the hasp from engaging the except at points closely bases and the surface of the plate, providing the hasp with an annular flange, 12, extending around its eye-portion whereby the height of the eyeportion is substan,- tially equal to the horizontal cross-sectional dimension of the eye-portion, as-shown in Fig; 2.

In order to confine the thrust to the bodyadjacent to their portion only of the hasp and thus to the base portion only of the bosses, 6 and 7 or similar devices whereby the hasp is pivotally mounted, the outer portion of the flange, 12, is so formed as to taper or retreat from the edge-portions of the hasp bordering the pivot-eye, 2, and bordering the neighboring,

end of the hasp.

WVhat we claim as new and desire to sec-o cure by Letters Patent is' 1. In a hasp-mounting and in combination, a hasp provided with apivot-eye; a supporting-plate having an integral tubular pivot-boss passing through the-eye of the hasp; and a keeper in the form of a staple having one leg passing through the tubular boss and secured to the plate, and its other leg secured to the plate outside of the eye of the hasp.

2. In a hasp-mounting anduin combination, a hasp provided with a pivot-eye; a

Copies of this patent may be obtained for bosses 6 and 7,

neighboringend of the hasp to abut against the other boss; and a keeper having two legs inserted through the respective tubular bosses and secured rigidlyto said plate;

4h In a hasp mounting and in combination, a hasp provided with a pivot-eye; a pivot passing throughthe pivot-eyeof the hasp; and a keeper overhangingthe pivoteye of the hasp, the hasp being adapted to swing freely upon the pivot andthe keeper,-

and having adjacent to its eye an outwardly extending flange whereby the clearance of.

the eye-portion of the hasp with reference to the keeper when thehasp is in locked position is substantially the same as its clearance in the swinging, movementsof the hasp, the outer portion of said flange retreating from the edge-portions of the hasp, whereby end-thrust'is confined .to the body-portion only of the hasp.

In testimony whereof, we have hereunto set our hands this 21st day ofSeptember WILLIAM C. MARTINEAU. CLARENCE R. MARTINEAII.

Washington, D. C.
