A VILLIAM XV. PURSELL, OF BERVICK, PENNSYLVANIA.

HASP-LOCK.

SPECIFICATION forming part of Letters Patent No. 447,698, dated March 3,1891.

Application led May 1,1890. Serial No. 350,206. (No model).

To @ZZ whom it may concern.-

Be it known that I, WILLIAM W. PURsELL, a citizen of the United States, residing at Berwick, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in Staple-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 to which it appertains to make and use the same.

This invention relatesl to locks which are especially constructed to be used in connection with and for fastening hasps.

The purpose of the invention is to provide a simple and compact lock which will be Water-proof, not easily picked7 and economical in construction.

The improvement consists of the novel features and peculiar construction and combination of the parts which will be hereinafter more fully described and claimed, and which are shown in the accompanying drawings, in Whioh Figure 1 is a front view showing the application of the invention. Fig. 2 is a plan View of the lock and the key. Fig. 3 is a plan section and end view of the locking head or-cap. Fig. 4t is aview of one half of the case or barrel and an end and side view of the key-guide. Fig. 5 is a side and end view of the other half of the barrel. Fig. 6 is a cross-section on the line X X of Fig. et of the oase or barrel and an end view of the locking-guide. Fig. 7 is a perspective front and rear end view of the locking-bolt. Fig. 8 is an enlarged view of the end of the barrel, showing the guide end of the locking-bolt in position.

The barrel or case, which is preferably cylindrical in form for economy of construction, is made in two parts or halves A A', which are secured together in any convenient manner, preferably by providing each with lateral wings a a at one end, which wings are riveted together and form a stop to limit the movement of the lock when inserted in the staple C, as shown most clearly in Fig. 1. Each ot' the halves A A is provided with stops b b', which are designed to enter notches on the edges of the key B and permit a turnin g of the same when the notches in said key coincide with the said stops. Obviously an endless number of locks may be constructed, in which no two keys will be alike,` simply by varying the number and changing the position of the said stops b o. The stops in one half of the case may be located in the same or a different plane from the stops b in the other half. It is preferred, however, to have the said stops b b located at different positions, as it renders the loc-k more difficult to pick. The locking-bolt D is journaled in the Aend of the case or barrel opposite that provided with the ears or wings a a', and its outer end is hanged or provided with lateral projections d, for the purpose hereinafter more particularly described.

The shank d of the locking-bolt is iattened at its inner end and passes through a guide E, which is tted between the halves of the case and is held in place by the lateral projections c, fitting in grooves d3, formed betweenthe said halves. This guide is adapted to have a longitudinal movement in the case and is pressed forward by the spring F, which is mounted on the shaft d. This guide E serves to lock the bolt D and hold it against rotation, and when pressed in by the key its proj ections e are disengaged from the said grooves in the case and come opposite an enlarged part of the said case, thereby enabling the guide and locking-bolt to be turned.

The locking head or cap G is adapted to be fitted on the end of the barrel or case and is provided on its inner side with the interlocking shoulder g, which is engaged by the flanged head or projections d of the lockingbolt and secures it in position. The projection H on the side of the case is constructed to enter a groove 7L in the said cap or head G and hold the same against turning when placed on the said case.

The key-guide I is a disk having an annular iange t', which is fitted in a groove t" in the case or barrel, and has an opening to permit the insertion of the key. The operation of the lock is as follows: Then the hasp is passed over the staple, the case, the lockinghead being removed, is passed through said staple and is held in place by adjusting the said locking head or cap on the end of the case which has been thrust through the staple and is secured thereon by turning the locking-bolt so that its flanged ond will overlap IOO the shoulder g in the interior of the said cap or head, which is accomplished in the follow ing manner: The key slotted at its inner end is inserted in the case and pressed in sufficient-ly far to bring the notches therein opposite the stops in the case, and also carry the guide E into the enlarged portion of the said case, when on turning the said key the locking-bolt will be rotated on its axis and effect a locking of the said cap. lVhen the key is withdrawn, the spring F will press the guide E back and lock the bolt.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A hasp-lock comprising a case having a stop at one end to limit the movement of the lock when thrust through a staple, a rotatable locking-bolt at the opposite end of the case, and a locking head or cap secured to the case by the said locking-bolt, substantially as set forth.

2. The combination, with the case and the rotatable locking-bolt, of the spring-actuated guide having engagement with and adapted to turn with the said locking-bolt,but free to move thereon, and havinglateral projections which are adapted to engage with the said case, and a cap adapted to be engaged by the said locking-bolt, substantially as set forth.

3. The combination, With the case having a stop at one end to limit the movement ot' the case when thrust through a staple and a rotatable locking-bolt in the case at the end opposite the said stop, having locking projections at its outer end, ot a locking-cap having an inner tia-nge, and an interlocking groove and projection between the said cap and case to guide the cap when placed on the ease to give proper direction to the lookin g-bolt head and prevent the cap from turning when in place on the case, substantially as described.

4E. A hasp-lock comprising a ease which is made in sections, each section having lateral Wings which form means for securing the said sections together and serve as a stop to limit.

the movement of the said ease when thrust through the staple, a locking-bolt inclosed within said case and adapted to have a nievement to secure the lock when in position, and a cap held on the case by the locking-bolt, substantially as set forth.

5. In a hasp-lock, the combination, with the case or barrel made in sections, each section having stops, of a key having notches in its edges to correspond with the position of the said stops, substantially as described.

6. The hereinbetore specified hasplock, composed of a case which is made in sections, each section having stops and lateral wings which serve as fastening' means for securing the sections together, a rotatable key-guide I, the locking-bolt D, the guide E, mounted on the shank of the locking-bolt and having a limited movement thereon, the spring F, for pressing the guide E back in the ease, and the locking head or cap (l, substantially as set forth.

In'testimony whereof I affix my signature in presence of two witnesses.

WILLIAM lV. PURSELL.
