Application filed January 3, 1920. Serial No. 349,164.

I '0 all whom it may concern:

Be it known that I, CHARLES Oscan TRACY, a citizen of the United States, and

a resident of Norwich, inthe county of New London and State of Connecticut, have i11- vented a new and Improved Look, of which the following is a full, clear, and exact description. y

This invention relates to looks, and has for an object to provide an improved construction in which a sliding hasp is used to connect the different parts of the lock mechanism, and has a retalning member for holding two doors or other devices together.

Another object in view is to provide a lock substantially of the padlock type in which. a sliding hasp is utilized, the arrangement being such that the hasp slides radially inwardly and outwardly to a locked and unlocked position respectively. y

A further object of the invention is to providea lock in which the hasp. is supported against the action of a hammer or other implement by a plurality of supporting members independent of the locking catch. 1

Another object of the invention is to provide a lock in which a sliding key is used,

and a pivotally mounted catch associated vith a sliding bolt, the arrangement being such that the bolt is locked when slidinglv moved intoa locked position and unlocked when the key is slidingly moved to a given position. a

In the accompanying drawing:

Figure 1 is a top plan view of a lock disclosing an embodimentof the invention, the same being shown applied.

Fig. 2 is a sectional view through Fig. 1 on line 2--2.

Fig. 3 is a sectional view through Fig. 2 on line 3-3.

Fig. 4 is a sectional view similar to the right end of Fig. 3, but with the catch shown in an unlocked position.

Fig. 5 is a fragmentary sectional view through Fig. 4 on line 5 5.

Fig. 6 is a detail perspective view showing the key guide embodying certain features of the invention.

Referring to the accompanying drawing by numerals, 1 and 2 may indicate doors which are to be locked together. or any other article or device desired. The lock connecting these doors is formed in two principal parts, namely the hasp section 3 and the lock section 4. The hasp section 3 provided with a casingb similar in outside appearance to the casing 6 of the lock section 1, though interiorlyit is quite different. As shown in Figs. 2 and 3, section 3 is provided with a bottom 7 having a slot 8 merging into an enlar ement or head 9 through Which the hea 10 of the bolt 11 is passed when being ad usted to the position shown in Fig. 2. fWhen the bolt 11 is extending at right angles to the bottom 7 the head 10 thereof will not pass through the opening 9 nor the slot 8, but will clamp section 3 in osition. Preferably the clamping action 1s such that the sectlon may easily slidetogether with the hasp or bolt 12. It will be noted that the hasp or bolt 12 provided with an arc-shaped flange or enlargement 13 fitting against the casing 6 while the bolt head 14. extends through a suitable slot 15 in casing 6 so that the shoulder 16 willinterlock with thelhook 17 of the locking catch 18. The head 14; isalso provided with an arc-shaped recess 19 for accommodating the bolt-20, which bolt is formed with a. headill fitting into arecess 22 in the top of the cas ing 6, while the body of the bolt extends through casing 6 and also through. door 1 so as to receive the clamping nut 23 and rigldly clamp the cas1ng6 inplace. The

casing 6 is preferably provided with a bottom 24 which is removably arranged in the casing .6, and is provided with a short eX- tension 25 fitting intothe notch 15 below the head 14., whereby the bottom cannot be rotated independent of the casing 6, nor can the casing 6 be rotated independent of the bottom. To prevent rotation of the casing 6 and bottom 24, a plurality of pressed out spurs 26 are provided, which are forced into.

the door 1, said spurs co-acting with bolt 20 to prevent any rotary movement, or in fact any movement whatever of the casing and the bottom. The catch 18 is pivotally mounted on a shaft 27 so as to freely swing thereon, said catch being acted upon by spring 28 so as to always have a tendency to move to the position shown in Fig. 3. The catch 18 is provided with an arm 29 having a plurality of arc-shaped fingers 30, acting in the capacity of tumblers, said fingers be ing arranged in different planes as shown in Fig. 5, so as to pass through the various openings 31 in a key 32 and also through the various openings 33 in the key guide or ward 34. It will be noted that the spring path of movement of the key, when the key is forced in it may freely pass the'tumblers so as to engage the catch near point without any hindrance from the tumblers.

If an improper key is inserted it will move in until it contactswith the catch at point 35, but cannot move the catch as any pivotal movement of the catch in a direction for releasing the same will cause the fingers or tumblers 30to press against the key. This will prevent any swinging movement of the catch if the key, is an improper one, but if it is provided with the proper slots 31 said slots will come opposite the openings 33 and permit the passage of the tumblers 30. In order to change the combination, the ward 34 is arranged in a slot in the bottom 24: and held therein by rivets or in any other desired manner. It is intended that this ward shouldbe positioned at different points in the slot according to the combination desired, though if preferred it could be always arranged at the same place and the slots or openings 33 varied. It is, of course, understood that the position of the fingers or tumblers 30 would be: varied to agree with the position of the slots 33. 1 What I claim is:

1. A look of the character described comprising a bolt formed with a notch, a lock 2. A lock comprising a sliding hasp formed with a bolt hcad having a hood at one end and said hood having a substantially T-shaped slot in the bottom, means formed with a head extending through said slot for clamping the hasp to a body so that the hasp may slide and also rotate after being disengaged, a lock casing fitting over said bolt head, and means in the casing for interlocking with the bolt head.

3. A lock comprising a bolt formed with a notch for'receivinga catch having an arcshaped notch in the end, said bolt having an arc-shaped shoulder, a lock casing fitting against said arc-shaped shoulder, a clamping bolt extending through the casing and fitting loosely against a notch in the end of the bolt, a pivotally mounted catch for looking said bolt and engaging the bolt in said notch, and means for guiding a key into the casing for disengaging the catch.

4:. A lock comprising a bolt, a casing into which the bolt projects, a pivotally mounted catch adapted to hold the bolt in a locked position, a ward for guiding a key into said catch for actuating the same, said ward being formed with a plurality of substantially transverse slots. and a plurality of areshaped fingers connected with said catch movable through said slots when said hey disengagcs said catch whereby the key must be of the correct shape to permit the passage of said fingers betore said catch can be disengaged.

5. A lock of the character described comprising a casing, a catch arranged in said casing for ei'igaging a belt, a ward connected with the bottom of: the casing and formed so as to be positioned at difit'eront points in said bottom for varying the combination, said ward being formed with a plurality of notches, and a plurality of fingers comiected with said catch movable through said notches when the catch is operated by said key.
