' LOCK.

SPECIFICATION forming part of Letters Patent No. 762,582, dated June 14, 1904.

Application filed January 23,1904. Serial No. 190,385- (No model.)

To all whom it may concern:

, Specifically the lock comprises the usual casing and a lock-bolt movable within the said caslng and provided with peculiar engaging means 1n the form of spring members carried thereby, which engage the casing at an aseer-.

tained .point in the movement of the lock-bolt and prevent displacement of said bolt.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for efiecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a lock embodying the invention. Fig. 2 is a vertical longitudinal sectional view through the lock. Fig. 3 is a detail perspective view of the lockcasing. Fig. 4 is a perspective view of the lock-bolt. Fig. 5 is a detail view of the key, peculiarly constructed for the purpose of disengaging the loek-bolt. Fig. 6 is a transverse sectional view showing the key in place.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings, the invention 7 comprises the casing which is of approximately oblong form in the preferable adaptation of the device. From the casing l are proif desired, as will be noted as the memjected the spaced bosses 2, which are provided with openings3, through which the lock-bolt 4 passes in its movement upon the casing. One end of the casing is closed, as shown at 5, and this end is provided with the key-opening 6. The other end of the casing is open,

the lock-bolt being provided with an end plate 7, which when the lock-bolt is secured to the casing in looking relation thereto closes the open end of the casing thereof. Within the casing and disposed a short distance from the open end of same are located a plurality of lugs 8, which lugs cooperate to prevent displacement of the lock-bolt 4, or, in other words,

constitute the engaging means carried by the casing, which locks the lockbolt thereto. Projected from the end plate 7, which is integrally formed with the lock-bolts, and extending in approximately parallelling relation to the lock-bolt are spaced arms 9 and a lower arm 10, located below the spaced arms 9 and approximately intermediate same in relative position. The arms 9 and 10 carry the engaging means of the lock-bolt, and said engaging means comprisesthe spring members 11. The members 11 comprise spring catches or plate secured at one end to the respective arm upon which it is disposed, the other end being freely movable for spring engagement or disengagement. The movable ends of the members 11 are adjacent the end plate 7 of the lock-bolt 4, and the said ends are adapted to engage the lugs 8 within the casing, as before described. The upper edges of the spring members 11, which are secured to the lower arm 10, project above the upper side of the said arm and being spaced apart form a guide-channel 12, which cooperates with the key 13, as will be readily seen hereinafter.

The key used in connection with my lock mechanism is of a special structure adapted to compress the spring members carried by the arms 10 and 11 and by such action permit disengagement of the said members from the lugs 8 within the casingla-nd unlocking movement of the lock-bolt 4E. The key comprises in its preferred form a handle 14 and a keybar 15, pivoted betweenthe spaced arms of the handle so as to fold between said arms when out of use. A bail 16 may also be provided to permit attachment of thekey to a ring or other analogous device. The key-bar is provided upon the under side thereof with three ribs 17, the outermost of which ribs are adapted to compress the spring members 11 of the lower arm and cause disengagement thereof from the lugs within the casing 1. The central rib forms a guide-rib, which is received in the channel 12, formed by the disposition of the spring members of the lower arm 10. Grooves 18 in the sides of the key-bar receive the arms 9, and the'spring members carried by these arms are compressed when received within these grooves 18 in a manner which will be apparent. The compression of the several spring members 11 is of course simultaneous for reasons obvious. The spring members 11 being disposed angularly as regards those carried by the upper and lower members 10 and 11 necessitate the use of a special key in order that they may be simultaneously disengaged. It is contemplated that the angular disposition of the members 11 may be varied in different locks, so as to clearly differentiate same from each other and prevent the use of a single key for more than one lock mechanism. The key, of course, would have its construction modified in accordance with the construction of the lock.

The look as described above is one for personal use or for transient application. To enable the lock to be permanently attached, the structure of the casing would be somewhat modified, and it is objective to manufacture the lock either for permanent attachment or of a form similar to that shown herein.

The movement of the key to cause disengagement of the spring members 11 also serves to project the lock-bolt from the casing when said members are disengaged.

Having thus described the invention, what is claimed as new is 1. In a lock, the combination of a casing having spaced bosses projected therefrom and open at one end, a slide-bolt movable in said casing and provided with an end plate closing the open end of the casing, spaced supportingarms projected from the end plate, spring engaging members secured to the spaced supporting-arms aforesaid, another supportingarm projected from the end plate and disposed beneath the spaced supporting-arms above mentioned and about intermediate same, spring engaging members carried by the lower supporting-arm, and lugs projected from the inner side of the casing and adapted to be engaged by the spring members of the support ing-arms aforesaid.

2. In a lock, the combination of a casing closed at one end and open at the other end, spaced bosses projected from the casing, a slide-bolt slidably mounted in said casing and provided with an end plate adapted to close the open end of the casing, spaced supportingarms projected from the inner side of the end plate aforesaid, spring engaging members secured to the upper sides of the said supporting-arms, another supporting-arm projected from the end plate and disposed beneath the first-mentioned supporting-arm and at a point about intermediate of same, spring engaging members secured to the sides of the lower supporting-arm and having their upper portions projected above the said supporting-arm to form a longitudinal groove, lugs projected from the inner side of the casing adjacent the upper end thereof and adapted to be engaged by the spring members of the supportingarms, the closed end of the casing being provided with a key-opening.

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