PADLOCK.

Application filed May 7,

To LZZ whom it may concern Be it known that I, JosnrH ALEXIS PHILIPPE DE GUISE, a subject of the King of Great Britain, residing at Sorel, Province of Quebec, Canada, have invented certain new and useful Improvements in Padlocks; and I do hereby deolare that the following is a fulhclear, and exact description of the invention, such as will enable others skilled in the art to which it appert-ains to make and use the'same y t The present invention relates to new and useful improvements in looks and more generally ,to' padlocks of the permutation type and particularly to an improvement on mv ,former United States Patent No. 1,060,23

01".- April 29,1913, I

The "primary object of the invention is the provision of a lock such as above referred to which canbe operated in the dark or by blind or deaf persons without necessitating seeing the-lock. or listening for the sound of the tumblers thereof.

Another object of the invention is the provision of a lock such as above referred toe-in i vhich the number of various combinations is unlimited, and which can be quickly and easily changed without necessitating the using, of a key or other tool.

v further object of the invention is the provision of a lock such as above referred to including a shackle and a series of tumblers arranged for locking the shackle in its closed position,'t0getl1er with a rotatable member by means of which the tumblers can be easily andreadily turned for the purpose of releasing the shackle and permitting the lock to be opened. y i

A still further object of the invention is the provisionof a lock such as above referred to,'which will be comparatively simple and inexpensive to manufacture, strong and durable m its constructlon, rellable and ef-v ficient in use, and readily operated.

Vith the above and other objects in view,

the presentinvention resides in the novel features of construction, formations, combinations, and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawgs, forming a partofthe present application and'in which;

Flgure 3 is a similar view showing the shackle released; 7

Figure 4 is a similar view showing the shackle in locked position; a

Figure 5 is a detail view of the locking spring;

F gure 6 is a top plan view of the lock; l hgure 7 is a horizontal sectional View taken on' the line 77 of Figure 1; and,

Figures from 8 to 23 inclusive are detail views. illustrating in section and in plan view the various' elements of the lock. Referring now to the accompanying drawings by corresponding characters of reference throughout the several views, the numeral 25 designates in general my improved lock which consists of a cylindrical body portion 26 having a central recess 27 formed theremQin which isdisposed a central shaft 28 which has secured at its lower end and rotatable therewith a thumb piece 29. This thumb piece 29 includes a milled head 30, the inner surface of which is provided with recesses 31 adapted to receive the lower side of the spring pressed ball 32 mounted in a recess 33 formed in one side of the cylindrical body portion 26.

The shaft 28 is fixed to the thumb piece 29 and is rotatable therewith being provided with a plurality of laterally extending pins 38 which are arranged in spaced relation and are designed to fit within the washers 39. The tumblers t0 are spaced apart by the washers 39. These washers 39 and tumblers a0 are provided respectively with notches il and 42 arranged in their edges for cooperation vwith the notches 43 provided in the long side 35 of the shackle 36.

iVhen the notches 41 and. 42 are in alignment with the notches 43. the shackle may be released as shown in Figure 2, but when the notches are out of alignment with the notches in the shackle, as shown in Figure ft. the said shackle is retained in said locking position.

A retaining cap 111 fits over the upper shackle from the lock.

end of the shaft and is held in position by a key 42, while a lower cap 44- is positioned upon the lower end of the shaft and rests upon the thumb piece 29. This cap 44 is formed with a groove 45 in which may inserted a circular spring key 46 which s normally sprung outwardly so that when the shackle is raised, as shown in Figure 3, this key will engage the groove 47 formed in the longer side of the shackle 86,,thus preventing the total displacement of the A spring 36 engages the lower cap 4.4 and washer 39 intcrposed between the cap and lowest tumbler 4O forcing the tumblers together and cansing them to frictionally engage each other and prevent their displacement. The washer 39 is provided with a notch 41 which functions in conjunction with the notches 41, 42 and43, as stated above. p

The tumblers 40 are each provided with a series of openings 48 in which may be positioned pins 49 arranged in the path of the pins 38 carried by the shaft 28.

Obviously as the thumb piece is turned around in various directions. the pins 38 will strike against the pins 49, thus rotating the tumblers 40 to bring the notches 42 in alignment withthe notches 43 for permitting the release of the shackle, while the spring pressed ball 32 will hold the thumbpiece 29 against any undersired displacement.

Indicating marks 50 are provided upon the periphery of the milled head 30, while corresponding indicating marks 51 are provided upon the lower end of the cyllndrical body portion 26.

In operation, the shackle 36' when locked is in the position shown in Figure 4, and,

when it is desiredto release the same, the thumb piece 29 is turned in either direction which causesthe upper pin 38 to strike against the upper pin 49of-the upper tumbler 40. As this tumbler is turned to register with the notch 43 in the shackle, it will be noted that the remaining notches 43 being somewhat larger will permit the slight upward movement of the shackle 36 to the position shown in Figure 3. thereby locking the upper tumbler 40 against movement and preventing further turning of the member 50. The shackle is pressed downwardly again, after which the thumb piece 29 may be rotated to bring the other notches in the tumblers .40 into alignment with the notches 43 to permit the turning of the shackle as desired.

When it is desired to change the combination, the shaft 28 is moved downwardly to the position shown in Figure 2 by exerting a slight pressure upon the thumb piece 29. When in this position, the key 46 may be removed and the tumblers and shaft removed in a single unit from the body polh tion 26. It is next necessary to remove the key 42 and thecap 41", which permits the tumblers to Slip from the shaft'after the pins 38 are removed. It is then a simple matter to remove the pins 49 placing them in the other openings 48, which changes the combination to any which might be desired, and as each of the openings 48 is marked, as

shown in the drawings, these numbers ap-. pearing thereon will indicate the new com-.

bination which can be either marked down or memorized by the operator. H

-From the foregoing description, taken in connection with the accompanying drawings, it will be manifest that a permutation padlock provided which will fulfil all of the necessary requirements ofsuch a device, and it should be understood in this connection that various minor changes in the specific details of construction can be resorted to within the scope of the appended claims, without departing from the 'spiritor. sacrificing any of the advantages of the invention.
