UNITED STATES ias-sam PATENT OFFICE.

LEE D. GIBSON, 0F DALLAS, TEXAS.

LOCK.

Application led October 3i, 1924. Serial No. 747,108.

To all whom t 'may concern.'

Be it known that I, LEE D. GIBSON, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improve-ments in Locks, of whichthe following is a specification.

This invention relates to locks, and is anV A further object of the inventionis thev provision of a lock construction in wh1ch the n lock casing is provided with a number of compartments, the plungers arranged 1n one compartment and the key adapted to be received in another compartment whereby opening of the lock by jimmying the key is prevented.

A further object of the invention is the provision of a lock in vwhich the locking plungers are actuated by a pair of pivoted dogs and are retained in ylocked position by a locking member, the dogs and the locking member being controlled by a single key.

In the accompanying drawings, I have shown one 'embodiment of the invention. In this showing: ,A

Figure 1 is a front elevation of the lock, parts being shown in section,

Figure 2 is a horizontal sectional viewon line 2 2 of Figure 1,

Figure 3 is a similar view on line 3 3 of Figure 1.

Figure 4 is a similar view on line 4 4 `of Figure 1,

Figure 5 is a vertical sectional view on line 5 5 of Figure 1,

Figure 6 is a detail view of portions of the lock disassembled, and,

Figure 7 is a perspective view of the pivl oted dogs.

Referring to the drawings, the yreference numeral 1 designates generally la lock casing which may be of any desired form and which is shown rectangular. The casing is formed of a block of metal which is cut out to form the various compartments of the lock and to provide partition walls separating the compartments. As shown, the casing is provided with a wall 2 parallel to one side, and spaced a slight distance there- ,tromtforrnrlg .a .Qhamber 3 for .the recepf tion ofone arm of the hasp. It is further provided with a transverse partition 4, forming a compartment 5 for the reception of the key and the key mechanism. Above the partition 4, there is provided a compartment 6, which isseparated from an upper compartment by means of a transverse wall 7. The compartment 5 is spaced from the hasp chamber by means of a vertical wall 8 extending from the bottom of the lock casing tothe partition ywall 4 and a casing 9 is arranged within this space. After the various parts of the lock have been assembled in the casing, a plate 10 is arranged over the `open face vof the casing and immovably secured thereto in any suitable Y manner, as by welding or the like.

The lock is'adapted to receive a hasp 10 which is formed U-shaped in the. usual manner and one arm 12 thereof is elongated and extends into the chamber 3 to a point adjacent the bottom of the lock casing. The other arm 13 is shorter and is adapted to barely enter the top of the lock casing when in locked position. The long arm 12 is provided with a reduced lower end 14, and a coil spring 15' is arranged around this reducedportion in the' bottom of the chamber 3 and is adapted to project the hasp when the lock is released. As shown, a knob 16 may be formed in the bottom of the chamber 3 and receive the end of the spring to guide it. In Figure 1 it will be seen that the casing 1 is extended up into the curve of the hasp 11 atla and leaving an opening 2a'for a staple or the liketo fasten the lock to the article to be secured. The purpose of this extension is to prevent the prying of the lock by inserting a pointed instrument between the hasp and the casing. The arms of the hasp are provided with substantially V-shaped notches or recesses 17 in alinement with each other and these recesses are adapted to receive the ends vof locking plungers 18, which retain the lock in closed position. As shown, the plungers are arranged in a compartment formed between the top of the lock casing and the partition wall 7. A coil spring 19 is arranged between the plungers and normally forces them outwardly.

The plungers are adapted to be actuated by means of a pair of pivoted dogs 2O which are arranged in the compartment 6 and are pivotally mounted .on pins 2l which are received in a ,transverse rib 22. The .Upper ends of these pins extend `through an elongated slot in the wall i and are received in not hes 23 formed in the lowerI tace of the plungers, These dogs are adapted to be i. tnated by a cani 24k arranged on the end ot a rod which extends through thc partition at. The roe is carried by a cylinder 2G, the lower end ot which is provided with an enlargement 2.7 abutting the inner et the bottom ot the loch casing. rlhe loch casing is provided with an opening in ali-nement with the cylinder, and a tubular spacing member 28 is secured to the cylinder and extends through this opening. Exteriorly or the casing, the tubular spacing member is provided with an enlargement 29 similar to the enlargement 27. The cylinder is provided with a groove 30 which, as shown, may be spirally arranged and is adapted to receive a lrey 3l which is twisted to lit in this groove. The partition 8, which iiorms one of the walls ot the casing 9, is provided with spaced cut out portions or notches A locking plunger 33 is arranged within this casing and is normally iorced outwardly by vmeans of a spring 34. This plunger is provided with a pair of grooves 35 in the tace adjacent the wall 8 and these grooves extend across the tace' et the plunger at an angle see Figure 5). The key 31 is provided with ribs or extensions' which are adapted to pass through the notches 32 and enter the grooves 35. rThe locking plunger is provided with an extension 37 which is reduced in cross section and extends through the compartment 6. The partition 'i' provided vwith an opening through which the end of the loching plunger 33 is adapted to pass and the locking plunger i8 is provided with a slot or notch 38 in alinement therewith when t-he plunger is in operative posi-tion to receive the end oi the plunger 33. Adjacent the end or the plunger, there is provided anenlargement forming a shoulder 39, which is adapted to Contact .rith the lower Lt'ace ot the parti-tion 7.

in operation, the hey is inserted in the cylinder 26 from the bottom of the loclr casing and rides in the groove 30. rll`he lingers project from the cylinder.` rihe cylinder then rotated by turning the hea-d of the key and the lower linger 36 iirst enters the lower groove through the slot '32. As

' the hey is rotated, this moves the plunger downwardly.

After a slight further rotation, the upper linger enters the upper groove and the continued rotation of the hey draws the member 83 inwardly, releasmg its upper end 'from the notch 38. At the same' time, the dogs 2O are swung on their `pivots by the cam 2li, the lower end of the being forced outwardly and the upper ends moving toward each other. This inward movement ont the dogs withdraws the locking plungers 18 from I:the rel? in the hasp and placesthe spring l) under tension. The spring l5 then projects the hasp and when the short arm l?) is projected, it is arranged above the top ot the casing and the loch is unlocked. Willen the key is turned through a complete halt revolution and withdrawn l'rom the cylinder, the parts are reaey to assume an operative position and as soon as the hasp is Yforced-i home, the spring 19 returns the `locking plungers l5 to their operative position. the saine time, the locking member 33 s forced upwardly by the spring 34 andv when the plungers 18 Aassume their yoperative position, the upper end of the member 33 enters the notch 88.

it is to be understood Athat the form of my invention herewith shown andidescribed is to be taken as a preferred example of the sa ie, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit et the invention or the .scope of the'sub-v joined claims.

l claim:

l. A lock as described and shown comprising a casingy a major 'locking yplunger and minor locking plungers therein, -a spiral key with lingers en gageable in slots in said maj or locking plunger for moving lsaid major plunger downward from engagement with one ot' said minor locking plungers; and means for releasing said minor locking plnngers troni engagement with the hasp lwhen the key is rot-ated to move vthe major plunger.v
