PINTLE LOCK Application September 4, 1934, Serial No. 742,586

22 Claims.

The invention relates to looks and primarily to that type of devices generally known as combination locks, operatable with or without a key, the locking and unlocking of which is controlled by movable members, each of which is moved to a certain predetermined position to effect the looking and unlocking of the lock on a shackle which may be of any form or construction.

The first object of the invention is to provide a combination lock operatable through combination means composed in part of pin tumblers formed of a plurality of sections of different lengths, certain of said sections being provided with annular grooves and provided with extending means in said grooves, for example in the form of expanding rings for foiling any attempt to feel the breaking point between movable lock members in which the said pin tumblers rest aligned, and by said means effect a greater simplicity with most solid, most reliable, compact and pick proof construction of locks of a character adaptable to various versatile uses and purposes in which it may be applicable, and provide means whereby the combination possessor may instantly manipulate the combination means in the dark, as well as in the light with the aid of a simple adjustable coin shape combination key, which can be made or manipulated to form any desired combination and to keep the combination secret from any possible onlookers while the lock is opened. It is further possible for the possessor of the combination to open the lock in case the combination key is lost, forgotten, or in case of light unnecessary.

Further objects of the invention are to provide a lock formed to favor a required shape as self protection against being caved in and twisted from implacement and having a shackle engaging means which will allow the general body of the lock to be constructed smaller, of less parts and thereby more solid, more powerful more durable, more burglar proof, more inexpensive, more reliable and capable by the simplest means of providing possibly billions of various combina- 5 tion codes from which any one code may be chosen.

The invention secures a further object with the provision of means whereby the combination may be more readily changed or altered if desired.

50 With the above and other objects in view, my invention consists chiefly in a pin tumbler lock comprising a compact interlocking body formed of two members adapted for relative movements and speedy extraction of pin tumblers with pro- 55 vison of means to engage a shackle or bolt and protect the shear line, pin tumblers having expanding means and pin tumblers with reduced ends extending to the outer surface of said body, and extends to consist of pin tumbler locks of the class varying in certain details of modification of 5 construction and combination of means and parts thereof within the scope of the invention, substantially as herein further described, and pointed out in the claims.

The foregoing and other objects which will ap- 10 pear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrangement of parts such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible 15 to various changes and modifications, and, therefore, I am not to be limited to the construction disclosed by the drawings; but I am entitled to all such changes therefrom as fall within the scope of my claims. 20

In the accompanying drawings, the number indicates what is throughout to be generally named the face member, and 2 the rear member of the lock which has pin tumbler sections 3-3-455-l--83 with expanding pin tumbler members 9 in groove 9' in certain sections, whereby the tumblers may be aligned to release face member l for movement to withdraw means it] carried thereby from engagement with the shackle H. The lock is opened by forcing a predetermined number of said pin tumblers together or separately to a predetermined depth to allow th opening and closing operation of the lock. Figures 1 to 6 show an arrangement of pin tumblers as shown in Figure 13. The tumblers 4 or i for instance, are moved into disalignment by the rotary motion of the lock on the extending bulge E2 on the inner side of the cup shape shackle flange l3. After alignment of pin tumblers shown in Figure 85 the face member I is moved to allow the release of the jaw It! from the shackle l I. It is also shown that means may be provided in all forms to partly or wholly cover the line of contactof the shear line faces of the face member and of the rear member as protection against attack, in that the extending means 55 and i5 are provided by the rear member 2 Fig. 5 and by the face member I Fig. 6, while like protective extending means are provided in Figures '7 to 12 by rings 56 and I6, and by a flange I3 in Figures 33 to 37, and by one flange l"! in Figures 39 to 48, by the general body of the lock in Figures 50 to 56, by the lock implacment in Figures 60 to 64 and by the inner flange 58 of the cylindrical form I9 of the rear member 2 in Figures '70 to 83. It is also understood that all forms throughout can be provided with coil springs 2B as shown in Figures 24 to '73. By the foregoing, it is seen that while the movable face member i is held keyed to the rear member 2 by integral extensions 2! and 2! Figure 6,- or by an insert 22 Figures 9 and 15 and the insert 22 Figure 16 corresponding to integral extensions 2i nd 2i of Figure 6 a projection it for shackle H is provided in each instance. It can be seen that the said means for connecting members i and 2 and locking the shackle are immovably mounted in a channel 23 of the face member l and movably held in the opposite channel 24 of the rear member 2: Figure 11 to hold or release a shackle I! ll mountable Within bores 25, 26 and 21 of lock members 28, 28 2 and I Figures 1 to 48.

The rear member as exemplified in Figs. 38 to 49 and Figs. '70 to 83 is provided with a flange which at its outer end |'l-| 8 is pressed inward to be narrowed by a press upon a fixed smaller diameter of the face member and thus movably unite both members permanently together by the forming of a rim as the final act of a method of assembling.

It can be further seen that a screw 29 (Figs. 29 and 30) or a tumbler (Fig. 21) resting with its end portion in the elongated groove 29' not only limits the horizontal movement of the face memher but also by withdrawal from said groove allows the removal of the face member following proper alignment of all pin tumblers and allows thereby the removal or readjustment of pin tumblers to provide a different combination.

Means 25, 2|, 22, 22 key the face member and rear member together in Figures 1 to 30, and allowing access to the pin tumblers by removal of the face member E from the rear member 2. The flange ll Figures 38 to 48 and flange I8 of Figures 70 to 83 prevents such action but allows in place access to the pin tumblers through a movable closure member 28 of the class for example shown in Figures 39 to 46, which is held movably mounted with key faces 30 against counter key faces 3! and held immovable by a movable shackle H with the bore 25. In place of a closure member 28' Figures 33 to 37, a closure member 32 (for the same purpose) is provided in Figures '70 to 78, wherein the combination is changeable by removal of the pin tumbler through the closure after the removal of the screw 32' from the rotatable closure member 32. Access to tumblers in Figure 50 for like change of the combination is possible by the removal of both the screw 33 and the key pin 34, and in Figures 60 to 64 by the removal of screws 35.

It can be seen in Figures 72 and '78 that the said closure member is rotatably mounted to allow the removal and replacement of spirally mounted pin tumblers and relative springs through the hole at any place. In the lock of modified forms, as exemplified in Figures 39 to 85 inclusive the members I and 2 are locked to perform proper functions by rotary movement, and that the jaws 36 shown in Figures 39 to- 45 have a projection 31 for movement in an oval groove 38 shown in Figures 39 to 45, the difference between the length and width of the oval (or a spiral) groove forces the jaws to move into and out of an annular elongated groove or other bolt engaging means about a shackle. Rib 39 (Fig. 48) engages groove 31 of jaw 35 and in the rotation of face member l carrying with it the jaw causes the same to move either to looking or unlocking position by reason of the eccentric shape of the rib. The rib is formed in a plate 44 mounted as shown in Figure 46. The locking and unlocking movement is provided in Figures 70 to 35 in a member l0 by a groove 34 Figure 72 for allowing the release and preventing the release of the bolt or a shackle. The pin tumblers vary in length or sections throughout but serve to perform like functions and the sections as shown in Figure 76 can be shifted to provide any desired combination as exemplified in Figures 84 and 85.

Any number of locks of the class may be operated by placing key points 45, 46 and 4? Figure 68 of a predetermined combination upon the combination key 48, which may be provided with handle 49 having a point extractor 49 for aiding the removal of key points from the combination key Figs. 6'7 and 79. It is to be understood that a combination key 50 Figures 31 and 32 can be of service in any pin tumbler lock in which the pin tumblers protrude from the surface of the dial face as the key of Fig. 31 being non-adjustable can be used only for looks having the.

same combination as that of the key. The combination key of Figure 32 is provided with holes 55 and an assortment of re-arrangeable sections 52 which fill partly or wholly the said holes to form a combination. The master key of Fig. 79 allows change of combination more quickly than the key of Figure 32 and may open a million locks 5 each lock of a difierent combination and may be conveniently carried by a means 53 Figure 82, which may carry with it for convenience a considerable number of paper dial leaves 54 having the combination and number of the lock stamped on each leaf.

When the combination is set on the combination key as for example as shown in Figure 79, the key is pressed on the dial face 55 Figs. 72 and 73 to allow key points 45, 46 and 41 to force the pin tumblers to alignment as in Fig. 85 to allow the turn of the combination key to rotate the face member l 360 degrees and allow the pin tumblers to fall automatically again in disalignment with the shear line M as shown for example in Figure 84. Rotation of face member l moves member it from one end of slot 10 to the other by means of spiral groove 44 thus placing said member I Q in position to contact the end wall of opening 58 in bolt ll to thereby retract said bolt upon the continued rotation of said face member, against the pressure of the bolt projecting spring. The spring will force the bolt to re-locking position limited by the extending pin ti which meets the bolt casing 62 (Fig. 75). The bolt casing is (for example) fastened by screws 63, 63' and through holes ea, 64 Figure 81 and the casing has a side recess 65 to allow the latch point 66 of the latch 67 to be moved into to lock the look from the inside and to prevent the look from being opened from the outside. It is to be understood that the bolt housing rests stationarily in the centrally located annular groove 68 on the rear member 2 to prevent the look from being drawn from iniplacement 69 while the door is locked. It is understood that the locking action of the latent? prevents the rotation of the lock and consequently prevents the look from bein opened from the outside.

The above described operation naturally forces the extending member Hi to one side within. the oblong hole it of the annular groove 68 Figure 71 and Figure 83, and the reverse operation of the look will force the said member It to the other side or free area 57 of the bolt and thus provide free rotation of the member 2 without moving the bolt, thus the lock is locked, and the application of a pipe-wrench to twist the lock open would only rotate the lock freely. Having thus described the lock of this class, I point to Figures 50 to 64 inclusive to show that I do not desire to limit myself to exact details of construction and that I am aware that a lock of this class may be reduced to a more simple form for certain purposes as shown for example in Figure 5G in which twin major parts possess the general form of a lock of the class in that two members ii and H form the combined interlocking jaws l2 and housing for tumblers of the class shown in Figures 13, 18, 58 or 68. The lock of Figure 60 75 with tumblers of the class Figure 13 can be 0perated with or without the use of combination key. Pin tumblers may also be provided with expanding rings 9 to foil the attempt to pick the lock. The members H and H are held together by a screw 33 passing through the hole 13 of member H into screw threads E4 of member H and said screw is locked therein by a key pin 34 (Fig. 5'7) passing through a hole 55 of member H and into the said screw to prevent the screw from being removed while the section i6 inclosed position covers the pin to prevent removal of the same while the lock is locked.

It may be shown in Figures 60 to 64 that the lock of the class can be applied to a door A or door frame B or vice versa, in that a face member i is fastened into the door A (Fig. 60) for ex ample within a rim i? followed by the rear member 2 screwed, riveted or welded to a door A. The rotation of member l moves a bolt 18 into and out of a recess '49 in the door frame B. The rotating face member l having a threaded hole to receive threads 8! of the bolt l8 moves the slidably mounted bolt 78 into the stationary rear member 2. The bolt 13 has flat side to prevent the bolt from turning. It is immaterial whether the threaded end of the bolt 78 is in the non-movable rear member and the slidable flat sided end of the bolt in the rotatable member, the movement in and out of the recess 19 would be the same. It is to be further understood that the end of the annular groove 3' of tumblers 3 may be flush with the face of the face member throughout from Figure 1 to Figure 74 inclusive, as shown in Figure 84. The adjustable combination key Figure '79 is also operatable in Figures 1 to 70 inclusive with allowance for minor changes in the length, location and number of tumblers in each lock. The adjustable key points 45, 46 and 47 fit the face of each lock. Tumblers may also protrude from the face of looks from Figure 60 to Figure 74 as in Figures 1 to 54, making adjustable combination key Figure 79 therefor also useable throughout in that the members 45, it and 47 Figure 68 may possess inward extending holes of the depth as of the length of key points 45 46 and 47'. It is evident that both the spiral arrangement of pin tumbler holes 43 (Figs. 70 to 79) and the circular arranged holes are applicable throughout. And that the combination key 48 Figure 79 has pins 82 to engage holes 83 Figure 74 to set the key 48 in line with grooves 84 and 85 Fig. 74. The key may have instead a groove or rib 86 Figure 65 as in Figure 67 to join a counter groove or rib on any look as exemplified in 84 Figure 64. The key may have instead a point 87 within a hole 88 (Figure 43) to fit into a recess 89 on the extension 90 (Figs. 38 to 46), or a key Figure 32 may have a bar 9| across a hole 92 as in Figure 31 to enter a groove 93 Figure 24, or key Figure 31 may have a point 94 as Figure 32 on its outer rim to fit into a recess 95 of a rim 96 as exemplified in Figs. 28 and 36. The key may be adapted by these minor changes to all looks of the class herein described.

Therefore, it can be seen by the foregoing that I have provided several specific, reliable compact locks and keys capable of fulfilling in each instance the use and purpose peculiar thereto within the general spirit of the invention which broadly aims to secure a lock practically pick proof by the employment of sectional tumblers around certain sections of which are placed expandable spring rings to aid in disguising the shear line. These tumblers are adaptable to the various locks disclosed anddo not interfere with the construction permitting free rotation to prevent twisting apart of the lock.

While I have. herein shown and particularly described the embodiments of my invention for said various uses by arrangements and re-arrangements of related parts for providing the same leading aim within the spirit of my invention I do not wish to be understood as limiting myself to the precise details of construction shown as further like changes can be readily made without departing'from the spirit of my invention.
