JOHN WATSON, OF MOULTRIEVILLE, SOUTH CAROLINA, ASSIGNOR 0F ONE-HALF TO FRED W. KELLAR, OF MOULTRIEVILLE, SOUTH CAROLINA.
LOCK.
I '0 all whom it may concern Be it known that I, JoI-IN l/VA'rsoN, a citizen of the United States, residing at Moultrieville, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Locks, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to new and useful improvements in looks and more particularly to looks of the sliding tumbler type adapted for use upon house doors and other similar places, the object of the invention being to provide a lock which cannot be picked or readily opened by unauthorized persons.
Another object of the invention is to provide a novel lock of this character which will possess advantages in points of efiiciency and durability, is inexpensive of man ufacture and at the same time is simple in construction and operation.
lVith the above and other objects in View, the invention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully described, pointed out in the claim and shown in the accompanying drawings, in which Figure 1 is an elevation of a lock constructed in accordance with my invention, one side of the casing being removed. Fig. 2 is a longitudinal sectional view. Fig. 3 is a detail elevation, the bolt being shown in a partly thrown position. Fig. 4 is a similar view, the bolt being shown in its locked position. Fig. 5 is a detail transverse sectional view showing the application of the key. Fig. 6 is an elevation of the key, a portion of one of the side plates being broken away to disclose the operating part-s. Fig. 7 is a fragmentary detail top plan view of the casing, and Fig. 8 is a fragmentary side elevation of the locking bolt.
Referring more particularly to the drawings, 1 indicates the lock casing, which in the present instance is shown in substantially rectangular form but it will be understood that the same may be made in any desirable form or shape. Arranged within the casing and disposed in spaced relation are the guide members 2 and 3 in which is slidably mounted the sliding bolt 3, provided at one end With an enlarged end 4:

adapted to engage the keeper 5 when the bolt is thrown to its locked position. The other end of the bolt is provided with a reduced portion 6 which is slidably mounted in the guide 3 and provided with an outstanding lug 7 adapted to engage the guide 3 to limit the outward sliding movement of the bolt.
Secured to one sideof the casing is an angular bracket 8 and formed integral therewith is a resilient retaining member 9 which is disposed at one side of the bolt and arranged in parallel relation therewith, said member being provided with an enlarged portion 10 having a cam surface 11 at one side thereof. A lug 12 is carried by the member 9 and adapted to engage within the spaced recesses 13 formed within one of the longitudinal edges of the bolt 3 to retain the bolt in a locked or unlocked position. From-the drawings, it will be apparent that the retaining member 9 and the bracket 8 are disposed at right angles to each other so that the arm 14 which connects the two serves to resiliently hold the retaining member in position. A second retaining member 15 is provided which is in the shape of a flat spring having one end secured to one side of the casing as shown at 16 and then bent upwardly to form a resilient retaining member having a lug 17 adapted to engage the recesses 18 formed in one side of the bolt 3' to help retain the bolt in a locked or unlocked position. An enlarged portion 19 is formed at the free end of the member 15 and is slit inwardly from each end and then bent to form two downwardly curved end portions 20. Arranged at one side of the bolt 3' and having its ends provided with the reduced portions 21 which are rot-atably mounted in the openings 22 of the casing, is the drum 23, said drum being provided with a longitudinal key receiving recess 24.
In the practical operation of my improved lock, a specific form of key comprising a finger hold 25 having the spaced parallel arms 26, one of which extends beyond the other and is bent at right angles as shown at 27 Plates 28 are secured to each side of the arms and one of said plates is provided adjacent one end with a longitudinal slot 29. Slidably mounted between the arms 26 is a sliding bar 30 having a rack 31 formed at one end which is adapted to engage With the circular toothed portion 32 of the pivoted member 33. A lug 34 is formed on the bar 3 and disposed within the slot 29 so that the pivoted member 33 may be readily operated when the end of the key is disposed within the casing.
In the peration of my improved lock, the key is inserted within the opening 35, which is provided at one side with notched recesses 36 to permit of the passage of the outer edge of the member The key passes into the longitudinal recess 2% of the drum 23 until the member can be swung to a position at right angles to the key by means of the sliding bar 30. The key is then rotated, the recess 37 in the outer end of the member engaging the cam portion 11 of the member 9 to disengage the lug l2 and the edge of the member 33 engages one of the curved portions 20 as shown in Fig. 5 to disengage the lug 17 which will release the bolt. In. the turning movement of the key, the outer end of the body of the member engages the V-shaped recess 38 formed in one edge of the bolt to slide the bolt into and out of engagement with the keeper 5.
From the above it will be readily apparent that by having the double lock retain ing members and by having them disposed upon opposite sides of the bolt that it will be almost impossible to pick the look. If one of the retaining members should be disengaged the bolt would still be held in position by the member upon the opposite side. It will also be apparent that by constructing the specific form of key described and reducing the size of the key opening, it also adds to the safety of the look.
It will be readily seen from the foregoing that I have constructed an efficient and durable lock of the above character which is extremely simple in construction and can be manufactured at a comparatively low cost.
lVhile I have shown and described the preferred form of my invent-ion, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing to hold the e615 in a locked or unlocked position and means for engaging said retaining members to release said bolt said means also engaging said bolt to actuate the same when released.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
JOHN IVATSON.
