HARTFORD, CONNECTICUT LOCK Application filed December 24,l 1930. Serial No'. 504,601.

My invention relates to locks.v ItY has for its object to provide an improved lock and more particularly, an improved lock of the combination type. A fur- 5 ther object of my invention is to provide such a lock having improved mechanism Operative on a plurality of bolts and controlled by improved Control mechanism. A still further object of my invention is to provide an improved controlling mechanism including a member forming a part of the combination mechanism and both longitudinally and rotatably adjustable into a plurality of control positions relative to the locking means and relative to a protecting means between said positions. These and other objectsl and advantages of my improved construction will, however, hereinafter more fully appear.

In the accompanying drawing I have shown for purposes of illustration one embodiment which my invention may assume in practice.

In this drawing,-

Figure 1 is a side elevation of a lock mechanism embodying my improvements, a portion of the rotating disc being broken away to facilitate illustration;

Fig. 2 is a view of the back of the mechanism shown in Figure 1, with the back plate removed and certain ofthe parts shown in section to facilitate illustration;

Fig. 3 is an'end View of the construction shown in Figure 1.; i Y

Fig. 4 is a sectional view on line 4-4 of Figure 2;

Fig. 5 is a sectional view on line 5--5 of Figure 2;V j

Fig. 6 is a sectional view on line 6 6 of Figure 2; 'and n Figs. 7 and 8 arev perspective views of details Y Inv this illustrative construction it will be noted that I have shown a case 1, herein having an inside cover plate 2 connectible thereto by 'suitable means as, for example,

corner screws 8, and such a case housing therein mechanism controlling the operation of bolts 4 and 5 projecting from one end of the case, while the mechanism in thel case is controllable by a rotatable member 6 forming part of the combination mechanism and on theoutside of the case, and a cooperating inside control member 7 loperable through the cover 2.

-Referring more particularly to the combination structure operated by the member 6, it will be noted that the latter is in the form of a disc carried onthe outer extremity of a shaft 8. This shaft also has fixed to the inner end thereof, as by a set screw 9 received in a suitable slot 10 in the shaft, a rotatable combination member 11. This in turn has a bevelled inner edge 12 carrying a suitable indication or mark 13 movable relative to asuitable` dial 14 formed on an annular stationary member 15 attached to the exterior of the case by suitable means, as screws 16. Herein, it will also be noted that the portion 12 on the member 11 projects over the member 15. The member 11 is also provided with a reduced portion 17 rotatable in a corresponding aperture inthe member 15, and,

further, carries a plate 18 abutting against.

the inner end of the member 11, which is rotatable in an annular groove in the other face of the plate 15 and attached to the member 11 by suitable means, as screws 19. Thus it will be evident that upon suitable rotation of the member 6, the member 11 may be adjusted so as to bring its mark 13 into any desired relation to the dial 14, while the member 6 may be adjusted longitudinally at will relative to the member 11.

Operatively'connected to the combination mechanism is alsoV the mechanism inside the case and controlling the bolt 4. I-Ierein, it

.will be noted that the shaft 8 has a toothed Vmember 20 connected to its inner end in any suitable manner as byy riveting at 21, in such manner as to be both rotatable with thel member 6 and shaft 8 and longitudinally movable therewith when the same are shifted longitudinallyv relative to the member 11. Herein, theinner end of the shaft 8 is also providedwith an axial bore 22 adapted to receive a vpin 23 suitably fixed on the cover 2 and co-operating with the member 11 in .gui-ding the shaft 8 in its longitudinal movement, while the case v1- is also' provided with a portion 24V forming onelimit or abutment for the toothed member 20. Here it will also be observed that when the member rests against this portion 24, its teeth mesh witl corresponding teeth 26 formed on a rack member 27 which carries the bolt 4 at one end and is reciprocable in the case 1 relative to suitable guides 23, while the bolt 4 is guided in the front edge of the case. Thus it will be vevident that in one longitudinal position ot the toothed memb-er 20, rotation of the member 6 in opposite directions will result in projecting or with-drawing the bolt 4.

Cor-operating with this bolt operating mechanism I have herein shown improved dogging mechanism controlling the same which, whilenot required, is desirably used therewith. Here it will be noted that this mechanism is also operable by the member Q0. It assumes the form of a co-operating dog 29 pivoted on a suitable pivot member 30 which is, in turn, attached to the case 1 and disposed in a slot 31 ext-ending longitudinally oit' the member 27 while spaced from the ends of the latter.` As shown, this dog is adapted to be swung about the member 30 from the full line position illustrated in Figure 2, wherein it is in back of the bolt 4 and accordingly prevents inward movement thereof and of the member 27, to the dotted line position shown in that figure, wherein the bolt and member 27 may move inward. Herein, in order to move the dog 29 from the full to the dotted line position, or vice versa,

the dog 29 is also provided near its pivot with a series of teeth 32 disposed in a plane parallel. to the plane of the teeth 26 on the rack member 27 and also adapted to be engaged by the teeth 25 on the member 20. Thus it will be evident that where it is desired to use this dog mechanism, the same may be actuated or released by moving the member 6 longitudinally in such manner as to bringthe teeth of the member 2O into engagement with the teethV 32 and then rotating the member 6 in the proper direction to throw the dog or release the same, with these operations preceding or'following the operations of the bolt 4 previously described.

yOperatively associated with the toothed member Q0 is also the operating mechanism for the bolt 5. Herein, it will be noted that the latter is reciprocable through a usual nected at its inner end to a rack member 33 j movable in guides 33 on the case and herein laterally offset from the bolt 5 and connected thereto by a relatively transversely disposed portion 34. Here it will also be noted that this portion 34 carries a pin or rod 35 projecting inwardly inside the rack 33. Moreover, it will be noted that this redis encircled by a suitable coiled spring 36. This spring in turn operates between the portion 34 and a projecting portion 37, on a member hereinafter mentioned, and having an aperture 38 through which the inner end of the rod extends. As shown, the portion 37 also has an upstanding projection 39 (Fig. 4) which is receivable in a suitable longitudinal slot 40 in the inner end of the rack member 33 and forms a guide for the latter. Herein, it will also be noted that a co-operating rack guide and spacing member 41 is held in position by suitable members 42 and carries the projections 37 and 39, while a co-operating member 43 similarly connected to the casing 1 also forms a co-operating guide for the member 33. Attention is also directed to the fact that the rack member 33 is provided with teeth 44 adapted to mesh with the teeth 25 on the member 20, and that it is also provided with the controlling member 7 which has its shank 45 fixed to the member 33 between the member 5 and the slot 40 in the member 33 and projecting out through a longitudinal slot 46 in the cover 2. Thus it will be evident that when the member 2O is adjusted longitudinally by the member 6 into mesh with the teetli 44 on the rack 33, the...

bolt 5 may be adjusted into or out of locking position by suitable rotation of the member 6, while in other longitudinal positions of the member 2O the bolt 5 will be controllable by the member 7 and form an ordinary spring.

adapted to prevent the operation of both bolts...

4 and 5 save bv one knowing the combination of the mechanism. Herein, this mecha nism assumes the form of a controlling member or tooth 47 which projects laterally toward the aXis ot the member 20 Vfrom the freeY end of a radially located support 48 and ter!V minates short of the axis of the member 20 in a plane between the planes of the rack 33 and teeth 32. Herein, I also provide an aperture 49 in the member 20 adapted to receive the.v

tooth 47 in a certain'angular position ot the member 2O about its axis and, accordingly, permit passage of the member QOfrom the tooth means controlling one bolt to the toothed means controlling` the other bolt as.

the member 6 is moved longitudinally. rlhus it will b-e evident that by reason of the tooth 47 and its (2o-operating aperture 49 in the aperture in the front edge of the case and conmember 20, it will be necessary Jfor one to know the proper position of the indicator 13 relative to the combination 14, before it will be possible lior him to move the member 20 from operation on one bolt to operation on the other.

Attention here is also directed to the fact that the member 43 is fixed in the inner face of the member 15, while an arcuate slot 50 is provided in the adjacent wall of the case 1 through which the member 48 extends. Herein it will be noted that this arcuate slot 50 extends Jfrom a point under the rack 27 (Fig.

at a point under the rack 27 on the opposite side of the axis of the member 20. Thus a yvery expeditiously substantial length of the member 15is exposed on each sideof the axis of the member 20. As a result of this construction it will be evident that a wide range of possible positions is provided for the member 48 in such manner as to enable the combination to be changed readily for different locks by simply locating the member 48 in different positions on' the same side or in different positions on the opposite side of the axis of the member 20.

Considering the operation of the mechanism described, let us assume that both bolts are in locking position, and that the dog 29 has been set. In this position of the parts, to unlock the same it is necessary, after pushing in the member 6 to a proper point to cause the member 2O to engage with the teeth 82, to rotate the member 20 to release the dog 29,. shift the member 20 slightly reversely ylongitudinally into engagement with the teeth 26 on the rack 27, rotate thev member 2O to unlock the bolt 4, shift the member 2O longitudinally out of engagement with the rack 27 rotate the member 20 so that its aperture 49 registers with the tooth 47, then shift it longitudinally past the tooth and into registry with the teeth 44 on the rack 33, and then rotate it to release the bolt 5. In locking the same, it will be evident that the bolt 5, being a spring bolt, will take care of itself, while the bolt 4 will be locked by successively actuating the rack 27 and dog 29. It will also be evident that the member 2O may be left in any of its operative positions or in planes between the planes of its operative positions. It will also be evident that not only may the combination of different locks be varied by varying the location of the member 48 on the member l5, but that whenever it is desired to change the combination of any lock, this may be readily done by'changing the position of the member l5 relative to the arcuate slot 50.-

It will be evident that the lock is exceedingly safe since the different longitudinal and rotary positions of the control member make it exceedingly-difficult for an unauthorized person to get the right combination. 0n the other hand, to one familiar with the combination, the lock may be unlocked or locked and conveniently. In practice it will of course be understood that the various longitudinal positions of the shaft 8 may be suitably indicated on the latter. It will also be evident that these figures with the rotation figure, which indicates the position wherein the aperture 49 will clear thetooth 47, will constitute a combination of longitudinal and rotary movement easy to remember. Herein, for example, the longitudinal positions in which the member 2O engages with the member 32 and with the teeth 44 of the rack 33, have been indicated by spaced lines and numerals 2 and 3 on the shaft 8. At the same time it will also be observed that the lock is not only readily openable from the outside by one familiar with the use of the same, but when the bolt 4 is withdrawn and the member 2() is out of engagement with the rack 33, also provides a construction in which the bolt 5 is usable as an ordinary spring latch. These and other advantages of my improved construction will, however, be apparent to those skilled in the art.

While I have in this application specically described one embodiment which my invention may assume in practice, it will be understood that the same is shown for purposes of illustration, and that the invention may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
