SPECIFICATION forming part of Letters Patent No. 660,571, daten october 3o, 1900.

Application filed July 13,1900.

To @ZZ whom it may concern,.-

Beit known that I, PETER O. GREENAWALT, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Hasp-Locks; and I do hereby declare' the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art t-o which it appertains to make and use the same.

My invention relates to improvements in locks, and particularly to hasp-locks.

It consists in a lock having a suitable hasp, a staple or keeper adapted to be engaged by the same, and a bolt carried by the hasp and adapted to engage the said keeper for locking the parts together.

It also consists in certain other constructions, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure l represents a hasp-lock embodying my invention, the hasp being folded back in an unlocked position. Fig. 2 represents a View, partially in elevation and partially in section, of the lock, the sectional portion being taken through the lock and staple to show the interior constructions of the same. Fig. 3 represents a detail view of a portion of the hasp, the face-plate of the lock carried thereby being removed to reveal the lockingbolt mounted in the casing. Fig. 4 represents a central longitudinal section through the hasp or staple lock; Fig. 5 is a detail sectional view through a portion of the staple or keeper, showing the means for limitingits movement. Fig. 6 represents a perspective view of the staple removed from its socket and the washer forl securing the same within the socket. Fig. 7 represents a detail perspective View of the socket for receiving and holding the staple. Fig. 8 represents an in-` verted plan view of the clip for pivotally supporting the hasp.

My invention is designed to providea hasp and staple lock which will have no separable parts likely to be lost, as when the ordinary padlock is used, and which though simple in Serial No. 23,522. (No model.)

construction can be made very strong and will not be likely 'to get out of order readily.

In the drawings I have shown anf embodiment of my improved lock which comprises a hasp l and a staple 2. The hasp is mounted upon one portion of the parts t0 be locked together, preferably upon a door` or other m0vable part, and is pivot-ally secured thereto by means of a plate or clip 3, which may be bolted or otherwise secured in position. The

, clip 3 is' made of suitable strength and is arched, as at 4, to surround the pivotal bearing 5 of the hasp l.' It is also provided with flanges through which screws or bolts may be passed to secure it in position. As seen in Figs. 4 and 8 of the drawings, the olipor plate 3 is preferably provided with a back wearing-plate, as 6, to receive the wear of the pivotal bearing 5 of the hasp. This plate is preferably provided with an angular contour, as seen in Fig. 8, adapted to lit snugly in a recess having a corresponding contour. The plate 6 is held in place when the clip or plate 3 is bolted or screwed in position, as will appear by reference to Fig. 4 of the drawings.

The hasp I may be made of any desiredv shape, a convenient form being shown in the drawings, in which the hinged portion is of a generally-triangular shape, while the oentral portion of the 'hasp is slightly enlarged to form a casing 7, adapted to accommodate a locking-bolt, as 8. The outer free end of y the hasp is' provided with an aperture, as at 9, which is of a suitable shape to fit over the staple 2. 'The bolt 8 is 'preferably a sliding bolt and extends into the casing 7, where it is engaged by. a spring l0, which engages the bolt 8 behind a shoulder 11 formed thereon. The inner end of the bolt 8 is provided with alug,as 12, adapted to be engaged by a suitable key for retracting the bolt. The key, which may be of any lsuitable design, gains access to the casingthrough an ordinary keyhole, as 13, and when turned will engage the tumblers of the bolt and draw thesame `inwardly against the action of the spring 10. The outer end of the bolt 8 projects-into the aperture 9 of the hasp, and when thehasp is closed over the staple it is designed to en- IOO . face of the socket 15.

v barrel from the keeper-socket 2l.

gage a recess formed thereinfor locking the parts together. The outer end or nose 14 of the bolt 8 is preferably' beveled, so that when it engages the staple 2 it Will be readily forced into the casing 7 by the contact with the saidv staple.

The staple 2 is designed to be arranged in proper relation to the hasp for locking the bearing-surface 18, formed in the socket 15. l

The inner end of the said -barrel is also provided With a shoulder or projection, as 19, which is arranged in the path of projections or shoulders 2O 20, formed on the inner sur- These shoulders or lugs 20 limit the revolution of the staple 2, permitting it to be turned hal fway around.

Above the casing 15 the barrel of the staple 2 is preferably slightly reduced again and is formed with a keeper-socket, as at 2l, for the reception of the bolt 8. Above the keepersocket the staple is provided With laterallyprojecting lugs, as 22 22, and a beveled boltengaging surface 23. The shape of the lugs and the beveled bolt-engaging surface are such as t0 [it exactly the opening 9, formed in the hasp, when the staple is turned in the position shown in Fig. l.. When the staple is turned in the opposite direction, the, lugs and shoulders on the said staple will not pass through the opening 9, as it does not properly register with the same in that position. The beveled receiving-face 23 of the staple is `arranged upon the opposite side of the staple- When the staple is in the position shown in Fig. 1, the hasp may be folded over the same and be forced down upon it, the beveled surface 23 serving to push the bolt 8 inwardly. The bolt will then rest against the cylindrical surface of the staple-barrel. After the lugs 22 have passed through the opening 9 the staple may be turned by means ot' its flattened head portion 24 until 'it assumes a position opposite touthat occupied by it in Fig. 1 or iintil it has been turned half-Way around. As soon as it has been turned half-Way around the keepersocket 21 will be presented to the end of the bolt or lock 8, which will immediately spring into the same under the influence lof the spring 10. In this position it Will be noted that it is impossibleto separate the parts Without turning the staple, since the lugs 22 22 are no longer in position to coincide With the aperture 9 and will therefore hold the hasp in place and also since the bolt 8 will not permit vthe staple to be 4turned until the said bolt has been retracted. This can only be accomplished by the use of a proper key,

which may be inserted in the keyhole 13 for the purpose of retract-ing the bolt, as heretofore mentioned.

1n order to movably hold the staple 2 in position in the socket 15, l preferably secure a Washer 25 to the innerend of the said staple,

and projection 26 on the said staple being forced through an opening in the Washer and headed, so as to rivet the parts together. This Will be apparent by reference to Fig. 4 of the drawings. v

vIt will be evident from the foregoing description that I am enabled by my invention to produce a simple though very effective hasp and staple lock and that the parts may be made asl strong as desired. A hasp and staple lock of this kind is well adapted for use upon all sorts of doors and gates. They are especially well adapted for use upon cellar-doors, barn-doors, farm-gates, car-doors, and the like.

Having thus described the invention, What l claim is- 1. A hasp and staple lock com prising a hasp, a locking-bolt carried bythe said hasp, and a movable staple adapted to be moved into one position to be engaged by the hasp, and
