IMPROVEMENT IN COMBINATION PADLOCKS.

Specification forming part of LottersPatent No. 135,992, dated February 18, 1873.

To all whom it may concern:

Be it known that I, JOSEPH KITTLE, of East Bend, in the county of Yadkin and State of North Carolina, have invented a new and useful Improvement in Combination Padlock, of which the following is a specification:

Figure 1 is a plan-view of my improved padlock, the upper part of the body or case being removed. Fig. 2 is a longitudinal section of the same taken through the line :20 w, Fig.1. Fig. 3 is a cross-section of the same taken through the line y 9 Fig. 1.

Similar letters of reference indicate correspondin g parts.

My invention has for its object to furnish an improved combination padlock, simple in construction, convenient and reliable in use, inexpensive in manufacture, and almost impossible to be unlocked without knowing the The invention consists in the mode of combining, with the indexrods that receive the staple of a padlock in their grooves, a rod placed transversely thereto, and work ing in grooves thereof, ashereinafter fully de scribed.

A B are the two parts of the body or case of the lock whichare designed'to be riveted or otherwise securely attached to each other. C is the staple, one arm of which is made long and the other short for convenience in passing it through the hasp, staple, or other object to be locked. The arms of the staple 0 enter and fit into holes in the body or case A B, which holes may be formed partly in each part of the said body or caseA B. Upon the inner end of the longer arm 'of the staple O is formed, or to it is attached, a toe or stop, D, which works in a recess in the body orcaseAB to prevent the staple from being drawn out any further than enough to allowthe short arm of said staple to be passed through the thing to be locked. E are rods or shafts, which are inserted in transverse holes in the opposite shafts E when said staple G is pushed in, are

formed semicircular notches, as shown in Figs. 2and 3, and in one side of each of the shafts E, at the point where the long arm .of the staple G crosses them, is formed a semieircir lar notch, as shown in Figs. 2 and 3.

By this construction, when all the rods or shafts E are turned so that their notches are toward the long arm of the staple O, the staple is unlocked, and may be drawn out as far as the stop 1) will allow. This it will be almost impossible to do without knowing upon what side of each of the shafts E the notch is formed, as, if even one of said shafts is only partially turned, the staple G will be held securely.

Upon the outer end of each ofv the shafts E is formed, or to it is attached, a disk, wheel, or knob, G, upon the edges of which are formed letters, figures, or other marks, one of which is directly opposite the notch in said shaft, so that, by knowing this particular mark of each shaft, the said shafts may be readily turned into the desired position.

Having thus described my invention, 1 claim as new and desire to secure by Letters Pat ent The combination, with rod F and notched staple O, of the index-rods E .G, annularly grooved to receive the former, and transversely notched to allow the latter to operate therewith, as described, and for the purpose set forth.

JOSEPH KITTLE.
