HASP-LOCK.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application led April 5,1905. Serial No. 253,969.

To a/ZZ wiwi/L it may concern: l

Be it known that I, PETER GRABLER, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hasp-Locks; and I do hereby declare the following to be a full, clear, and exa-ct description of the invention, such as will enable others skilled in the art to which it app ertains to make and use the same.

rIhis invention relates to certain new and useful improvements in hasp-locks.

The invention has for its object the combination, with a has p, of a spring-latch, whereby said hasp is locked against detachment from its retaining device when the parts are engaged.

A further obj ect is to provide simple and efficient means whereby the bolt of the lock may be held against movement.

A further object is to provide a simple and inexpensive strike for a hasp-lock.

To these ends the invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of my improved hasp-lock complete, the top casing of the lock being removed. Fig. 2 is a plan view of the lock, illustrating the positions of the parts when the bolt is held against movement, said bolt being shown in dotted lines. Fig. 3 is a similar view showing the positions assumed when the bolt is free to be moved. Fig. 4 is a detail view of the bolt. Fig. 5 is a similar view of the boltengaging device. Fig. 6 is a detail view of the strike. Fig. 7 is an edge view of the hasp, lock, and strike in locked position, the casing being shown in section.

Referring to the drawings, 10 designates a hasp of usual form provided with an opening 11 to receive a staple or other securing means and an opening 12 at its opposite end to receive the strike. Said strike comprises an angular plate 13, one member of whichis provided with a curved or cam edge 14, terminating in a notch 15 the other member of said plate being provided with holes or openings to receive screws or other securing devices.

The locking mechanism is contained within a casing 15, secured to the hasp by any suitable means and provided with forward and rear openings 16 17 to guide the lockingbolt 18, the latter being also guided by means of a slot 19, embracing the sleeve or bushing 20, which is adapted to receive the locking-bolt.

operating-key. Said bolt is provided at its forward end with a thickened portion 21', having a rounded edge and forming a shoulder 21, the purpose of which will be later described. rIhe rear end of said bolt is bent down to pass through the opening 17 and is provided with a horizontal portion 22 and an upturned extension or iinger-piece 22. The space between the thickened portion 21 and bent portion 22 and the contiguous face of the hasp forms a chamber O.

The tumblers may be of any preferred number, and, as shown, each comprise a pivoted spring-pressed member 23, having notches 24 to receive the pin 25 upon the locking member 26, the latter being pivoted at 27 to the hasp. The body portion of said locking-plate is substantially circular and provided with an approximately centrallylocated hole or' opening 28 to permit free movement of said member without interference from sleeve 20, said hole or' opening being provided with forward and rearward inclined surfaces 29 30, terminating in a notch 31, adapted to receive the bit of the key. Extending forwardly from the body of said locking member is a tangentially-arranged arm or projection 31', projecting into chamber O and having a bent or shouldered end 32, adapted to engage the shoulder 21 of the It will be noted that the tumblers 23 extend across the face of plate 26 approximately parallel with the arm or projection 31', spanning the open space formed by the inclined key-engaging faces 29 30.

It will be observed that the bolt reciprocates across the face of the locking member 26, the locking-arm 31 being normally to one side of the path traversed by the shoulder 21 of the bolt when the latter is reciprocated, thus leaving the latter free to be moved back and forth under pressure upon the iingerpiece 22 or under the iniiuence of its impelling-springs. When it is desired to lock the bolt against movement, the key is inserted, and the bit thereof passing off the inclined surface 29 into the notch 31 moves the tumblers to disengage them from the pin 25, permitting the key to swing the locking-plate 26 upon its pivot and to bring the shouldered end 32 of the arm or projection 31 under the shoulder 21 of the locking-bolt, thus preventing rearward movement of the latter, the bit of the key in its continued movement passing out of the notch 31 and along the inclined surface and back to its original position.

IIO

When the parts are thus locked, forward movement of the bolt is prevented by the finger-piece 22 and rearward movement is prevented by the locking plate or member 26. To unlock, it is only necessary to reverse the foregoing operation. In practice the lock is normally in the unlocked condition, Whereb y When the hasp is moved over the strike 13 the rounded edge of the bolt will slide over the curved or cam edge lll, being retracted against the action ot' its springs, and when opposite the notch. 15 Will spring into the latter, holding the parts in engagement. Vhen desired to unlock or cisengage the parts, it is only necessary to Withdraw the bolt by moans of the linger-piece 22. When it is desired to secure the parts against disengagement, the bolt is locked, as heretofore described.

The advantages of my invention Will be at once apparent to those skilled in the art to which it appertains. It Will be particularly observed that I have provided a hasp-lock with a spring-bolt and means whereby sair-fL bolt may be securely locked against Withdrawal. It Will also be observed that I have proviiled a hasp-lock which is exceedingly simple and compact in construction and ellicient in operation. Another advantage is that by means of my improved lock-strike the parts are automatically locked by placing the hasp in position thereover.
