Santa Fc, N. Mex. Application March 1, 1937, Serial No.`128`,537 2 Claims. This invention relates to padlocks and has for the primary object the provision of a device of this character which will exclude rain to prevent the movable parts lwithin the lock body 'from rusting and becoming inoperative or to prevent the accumulation of water therein to freeze in cold Weather and interfere with the operation of the movable parts. With these and other objects in View, this in l l) vention consists in certain novel features of con struction, combination and arrangement of parts to be hereinafter more fully described and claimed. For a complete understanding of my invention, reference is to be had to the following descrip tion and accompanying drawing, in which Figure 1 is a vertical sectional View illustrat ing a padlock constructed in accordance With 2O my invention. Figure 2 is a sectional view taken on the line 2-2 of Figure 1. Figure 3 is a sectional View taken on the line 3-3 of Figure 1. Figure 4 is a sectional View taken on the line 25 4-4 of Figure 1. Figure 5 is a plan view illustrating a key for operating the padlock. Referring in detail to the drawing, the nu meral I indicates the padlock outer shell or body, the same being of substantially rectangular lon 3O gitudinal and transverse section, and having a chamber 2 opening through the bottom. The body l has a recess 4' disposed laterally of and communicating with the chamber 2 and located 35 in the lower portion of the body. A passage 5 is formed in the body and extends from the top of the body to the recess 4’ to receive a shackle 5. The shackle 6 includes leg portions 'l and 8 and the leg portion 8 is of a greater length than 40 the leg portion 'l and is received in the passage 5 and enters the recess 4' while the leg portion l may move into and out of a. notch or recess 9 formed in the top Wall of the body. The leg 1 oi" the shackle 6 when moved out of the recess 45 9 permits the shackle to be readily adapted to a keeper. The leg portion 8 of the shackle is free to slide in the passage 5 and also rotate. How ever, the leg portion 8 has a comparatively tight fit with the walls of the passage 5 to exclude 50 moisture, rain or the like from the recess 4'. - A block or support l0 is mounted in the cham~ ber 2 and has formed therein a key opening or passage Il, one end of which opens through the bottom of the support. The support is provided 55 at the bottom with a flange 4 which ñts snugly against‘the bottom edge of the shell or body I to prevent entry of water into the chamber 2, Yin the body. Rivets or other connectors I2 are passed through the body I and support In to rigidly secure the parts together. Formed on Ul the support ID are guides I3 and I4 and which are arranged -at'right angles to each other. A locking bolt I5 is slidably supported by the guide I3 and the guide I4 slidably supports a member I6 which parallels the leg portion 8 of the shackle 10 and is connected thereto by a link Il. The leg portion 3 of the shackle is acted upon by the spring I8 and the member I6 is acted upon by a spring I9. The springs I8 and Ill urge the leg portion 8 of the shackle 6 and the members I6 in the same direction. The spring acting on the leg portion B of the shackle disengages the leg portion 'l from the Arecess 9. A spring 20 acts on the locking bolt I5 to urge the same in a position to overlie the member I5 and to retain said member against movement under the influence of the spring I9. The member I6 being held in the position stated by the locking bolt holds the shackle 6 or the leg portion 8 from movement under the action of the spring I8 and with the leg portion 'I extending into the recess 9. Formed in the support I0 is a chamber 2I in which is-pivotally mounted a series of superim posed tumblers 22 each having a slot 23 in one end and a key slot 24 partially surrounded by a shoulder 25. The slots 23 open outwardly to the ends of the tumblers and are provided with branches 26. A pin 21 is secured to the locking bolt and extends through the slots 23 and when the locking bolt overlies the member I6 the pin occupies the branches. 26 preventing the locking bolt from being retracted from engagement with the member I6, consequently securing the shackle 6 against being moved to a released or unlocked position. Leaf springs 28 act on the tumblers to position them so that the pin 21 enters the branches 26 of the slots 23. The locking bolt has a key opening 29 and located adjacent thereto is a shoulder 30. A key 3| is provided for actu» ating the tumblers so asV to position said tumblers with the pin 21 lying in the slots and out of the branches. The key 3| also extends through the key opening 29 of the locking bolt wherebyY the same may be retracted against the action of the 50 spring 30 by the rotation of the key. The key has projections or bits for the actuation of the tumblers and the sliding bolt by engaging the shoulders 25 and 30. Thus it will be seen that this padlock is simple to actuate by a key and 55 2 2,109,413 when locked it will eiîectively prevent the shackle from being moved into an open position. Fur ther, it is to be noted that the construction of the body and the connection of the shackle thereto is such that water and moisture will be eX cluded from the Working parts inside of the body chamber and opening outwardly through a face of the body, said body having a recess, a shackle including leg portions, with one of said leg por tions entering the chamber by Way of said pas sage and the other leg portion adapted to be moved into and out of the recess by sliding and rotating said shackle, a member slidable in the chamber, means connecting said member to the shackle, spring means acting on said shackle and member, a support in said chamber and hav ing a key passage to receive a key, a locking bolt slidable in said chamber to engage said member either when the shackle is open or closed. What is claimed is: l. A padlock comprising a body having a cham 10 ber and a passage communicating With said chamber and opening outwardly through a face of the body, said body having a recess, a shackle including leg portions, With one of said leg por tions entering the chamber by way of said pas , for securing the shackle in a locked position and 15 sage and the other leg portion adapted to be having a key opening, a spring acting on said moved into and out of the recess by sliding and locking bolt, tumblers pivotally mounted on said 15 rotating said shackle, a member slidable in the support and having slots provided with branches, chamber, means connecting said member to the a pin secured to the locking bolt and extending shackle, spring means acting on said shackle and into said slots, springs acting on said tumblers 20 member, a support in said chamber and having to position the latter to receive the pins in the branches of said slots, said tumblers having 20 a key passage to receive a key, a locking bolt slid able in said chamber to engage said member for key openings to receive the key whereby the tum blers may be actuated by said key and the bolt securing the shackle in a locked position and hav slid by the rotation of the key with the pin ing a key opening, a spring acting on said lock ing bolt, and tumblers carried by said support moving in the slots of the tumblers to free the member connected to the shackle and permit 25 and connected with the locking bolt. said shackle to move into unlocked position. 2.
