To all whom t may concern.'

Be it known that I, SAUL SHALER, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Combination-Padlock, of which the following is a full, clear, and exact description.

This invention relates to pad locks and `has particular reference to combination locks or such as may be manipulated without idmong the objects of the invention is to provide a pad lock having a frame or body, a removable shackle and a plurality of finger operated tumblers constituting the means for locking the shackle in the body, said tumblers being provided with index characters serving to establish the proper combination whereby the shackle may be removed when the tumblers are set in a predetermined position.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a side elevation of my improved lock.

Fig. 2 is a vertical section of the same.

Fig. 3 is a perspective view of one of the heads.

Fig, 4 is a plan view of one of the bod plates; and y Fig. 5 is a horizontal sectional detail on the line 5-5 of Fig. 2.

Referring` n'ow more specifically to the drawings I show my improved lock as comprising a body 10 including right and left heads 11 and 12 connected by means of any suitable upper and lower plates 13 and 14.- respectively, adapted to be rigidly secured to the heads by any suitable means.

The heads may be made of any suitable metal or its equivalent and are tubular each having a vertical bore 17 of any suitable size or form in cross section being indicated as rectangular. The inner Wall 18 of each head or the wall constituting the face directed toward the opposite head is preferably flat and smooth, while the opposite or outside wall 19 thereof is rounded although an)1 other form may be substituted for the senncylindrical surface 19. Said inner wall 18 is provided with a pair of horizontal drill holes 20, the axes of which are in horizontal alinement with the corresponding holes of the opposite head. These holes are materially larger in diameter than the Width of the bores 17.

The bottom plate 14 is preferably solid or imperforate, while the upper plate 13 is provided with slots or holes 21 re 'stering with the upper ends of the bores 1 and of the same size and form.

The shackle 22 comprises a loop or bail 23 and a pair of parallel shanks or legs 24. The form or cross section of the Shanks is substantially the same as that of the slots 21 and bores 17 into which the Shanks are adapted to be projected for locking the shackle in the body. The bail portion of the shackle is provided with shoulders 25 or equivalent means to limit the movement of the Shanks into the body heads. When the shackle is inserted into the body and the shoulders 25 impinge against the upper plate 13, notches 26 formed along the inner edges of the shanks 24 lie in registry with the holes 20, the vertical dimension or length of the notches being the same as the diameter of the holes 20.

The space between the upper and lower plates 13 and 14.- and horizontally between the two heads 11 and 12 is substantially filled by means of a plurality of pairs of tumblers 27 each of which comprises a preferably cylindrical portion, the inner end of which may be knurled at 27 while at its outer end each tumbler has a central axial trunnion 28 fitted into a hole 20. Thus each of the tumblers at its trunnion has dlrect bearing in one of the heads, while at its end adjacent to the alined tumbler of the same pair has a dowel connection 29 with the other alined tumbler. The dowel 29 is long enough to constitute a substantial support for the middle or adjacent end portions of each pair of tumblers. The dowel may be rigidly connected to one of the tumblers and have loose engagement only wlth the other tumbler, or for convenience in assemblagethe dow'el .may have 4,m0.vable conneci vvidthof whichis substantially the .same asy the thickness Aolf the Shanks; jlfhe length of eachof-the kerfs 31 is parallelfto the Shanks and hence perpendicular to the axis .of ithe tumblers. s

- F rom the foregoing .specific description ,of

the .mechanism .its ymode A:of operation wiflljbe appreciated it .is thought .from the following' summary: Each tumblervis :provided -with index characters 32 represented as .the `digit numerals, although they might be glettersor numbers of a higher order. These index characters .have reference .to pointers 33 formed on one sideof the Aheads opposite the several tumblers.-v :The `index characters are formed on the tumblers 4in vany `desired relation to the kerfs whereby any .-dGSIBdxQOm.- bination of the index charactersl may be yprovided `for Aany individual lock. When the prescribed characters `of a lock are adjusted.'

' inregistry with the pointers '33 all of the kerfswill-lie inthe 'same plane, namely, the plane of the shackle shanks, thus setting the shacklefree to be ldrawn'from the fbody. VVlhen, however, anyone or more of; the turn.-

1 1 blers .are turned slightly` fromfthis ,opening position the shackle will be locked from removal ldue to the fact that least 4O'Ilno'f the shoulders 3.4: justbeglow the trunnions will strike against the cylindrical surface of i any trunnions tur-ned -rLOm .the aQresaid opening position.V Thus it will be seen that the shackle may be `easily locked from re, moval and the Opening 0f the lock. may easily be eected by any one-familiar with thecombina'tion of the particular lock. y For any I one unfamiliar with. the combination the :task of opening the lock is practically hopeless. .l y The dei/ice is simple and cheap Of struction easy .0f manrulatsn and Strong and reliable iny practice. Eurthermgre it is not liable to get cut 0f order andannot fail toprovide for the; direct removal; 0f' the shackle when the Prflper' combination is observed. i vf The kerfs 31 be formed ill the ends ofthe trunnonjs 28 lin any desired relation to the axes of the trunnions, but nreferably I arrange @he wall-sottile kerfs parallel-te said axes.- andi slightly on? centerr as indicated in .exaggerated (leeres-l br they centrallyy drawn dot and @flge 3 and In other words while thekrfs-ar'e all adapt* ed to occupy thesame vertical plane and the shanks 24 of the shackle likewise lie in the ,Same plane it follows that the ,holes 2l .and `,tlie bores 17 'must'fbe similarly oset from 'the central stri,1c-tionit5 ollows that there can be but one lane of the lock. By this conopening position or adjustment of the several. tumblers 27. In other words yif the kerfs were central of the tumblers' there might be two different opening positions or adjustments of the tumblers, one position being the one intended `and the kother being the one 180 .degreesgremote therefrom.
