HASP-LOCK.

To. all whom 'it may concern."

Be it known that I, ALFRED L. BUCKLAND,

a citizen of the United States, residing at,

. essaiy to unlock the same by means of a ke;T

orthe like before detaching the hasps from the staples or Akeepers used in connection therewith.

`The object of the invention is to provide'a latch on. which the lock is carried, said lock including a tumbler designed to engage .the

,hasp for the purpose of holding the latch Aagainst movement with relation to the hasp.

A further object is to provide a lock which is of simple, durable and efficient construction, which cannot be easily tampered with, and which does not detract from the appearance of the hasp or add materially to its cost.

With these and other` objects in view the invention consists .of certain novel details of construction and combinations of parts hereinafter more fully described and'pointed out in the claims. A l

In the accompanying drawings the pre-vv ferred form of the invention has been shown.

In said drawings z-Figure 1 is a front elevation of a has'p embod ing the present improvements, the latcheing shown'out of locking position and. the casing of the lock beingbroken away. Fig. 2 is a longitudinal section through a portion of thehasp and through the` latch and lock thereon, said latch being'shown locked against movement with relation to the hasp. Fig. 3 is a section on line A-B Fig.,2.

Referring to the figures by characters of reference 1 designates the body of the hasp, the same being of the ordinary form and having a slot 2 therein adjacent one end for the reception of a keeper or staple, whilean tends from the hooked end of the latch and in a direction opposite to the'hook said arm constituting a handle to facilitate the raising ofthe latch. A stud 8 extends laterally fromthe arm, and is designed to come into contact with the hasp 1 and thus limit the movement of the latch in one direction. If preferred -a notch 9 may be formed in the latch 5 close to hook 6 so as to receive the staple or keeper, as will be obvious.'

The latch 5 is enlarged at a point between the ends, as indicated at 1,0, and riveted or otherwise secured to this enlarged portion is a lock housing 11 having an elongated-'come Ear'tment 12 therein in which is mounted a ow spring 13. nThis spring bears atan in termediate point upon the enlarged middle portion 14 of a spindle 15. The ends of this spindle bear within sockets 17 and 18 formed Patented April i3, i909.

in opposite walls of the' compartment 172,- the socket 18 being open atits outer end and enlarged to receivea key (not shown). That ortion of the spindle projecting into the enarged end of. the socket 18 is preferably an gular in cross section as indicated at 19, so as to be engaged and rotated by a suitable key. A tumbler 20 extends from the enlarged portion of the spindleand is preferably inthe form of a rectangular plate designed to assume a os'itionv either within a slot 21' formed in t e latch 5 and opening into compartment12, or in the opening 4 heretofore referred to. The enlarged portion 14 of the spindle has two flat faces arranged atright angles to each other, and eitherof these faces isdesignedto be contacted bv the spring 13, it being seen therefore thatA said spring will coperate with these faces to hold the tumbler 20 in either of the two po sitions referred to'.

It is to be understood that the tumbler 20 is normally disposed Within the slot 21 and compartment '12, the spring 13 serving to yieldingly hold it insuch position. There is nothing to prevent latch 5 from being swung into or .outof locking position as long as the tumbler is thus located, and when the hook I 6 is in its normal position across slot 2 the stud '8 rests on the upper edge of the haspA and tlie opening 4 registers with the slot 21. W'hile the parts are thus located the latch may .be secured a ainst movement with relation tothe hasp by placing a proper key in engagement 'with the exposed end of spindle 15 and turning said spindle so as to swing the tumbler 20 into the opening 4. Said tumbler will beheld in this position by the spring 13 contacting with the other flat face on the enlarged portion 14 of `the spindle. is long as the tumbler is located Within theY opening 4 it obviously becomes impossible to swing the latch with relation to the hasp.

.In order to lunlock the hasp it irst becomes necessary to swing' the tumbler 2O out ol' the opening 4, and this cannotV be dene ol course unless the proper' key is used. l V

lt will be seen that a hasp such as embodied in the presentinvention is verj)7 simple vand efficient, and does not detract from the.

appearance of the hasp. Such a device dispenses with the use of a padlock, and is advantageous, becausev there'is no danger of the lock Ibecoi'nin'g misplaced when the hasp is unlocked.

It is-of course to be understood that vari.- ous changes may be made inthe construction and arrangement of the partswlthout departing Afrom the spirit or sacrilieing the advantages oi the inventionl What is claimed is: Y 1-. yIn a device ofthe class described a hasp having a tumbler-receiving opening in one face, a `keeper vengaging latch pivotallv mounted upon the hasp and movable in a plane parallel with the apertured face of the hasp, and a lock carried by the latch, said. lock including a tumbler shii'table 3. A device of the class`described compris` ing a lrasp having a tumbler-receiving opening, akeeper-engaging latch pivotally mounted upon the hasp, a lock casing carried by and lined with relation'to the latch, said easing having anopening therein, means upon the latch and coperating with the hasp for supporting the latch with its opening in register' with the opening in 'the hasp, and a locking member lnovably mounted Within ,the casing and shiftable into the registering c openings. 4l. In a device of the class described a hasp having an opening therein, a keeper-engaging latch pivotallv mounted on the hasp, a lock casing fixedly mounted on thelatch, there being an opening in the latch, means upon the latch for supporting'the same with the two openings in register, a spindle mounted'for rotation within the easing, and a tumbler movable with the spindle and into the registering openings.

5. ln a device of the vclass described a hasp having 'an opening therein, akeepe`r-engaging latch pivotally mounted on the basp, a lock casing xedly mounted on .the latch, there being an opening within the latch and -opening into the casing, a key actuated spindle within the casing', and a locking member movable with the spindle and shiftable into the opening in thehasp to hold the.

latch against movement with relation tothe hasp;
