This invention relates to'locks, and more particularly to a lock system so designed that a number of different locks may be made from many of the same identical parts. Moreover, the mechanical features of the lock proper are so designed that the lock structure. including the case in which it is mounted, may be employed for either a mortise lock set into a mortise inthe door or what is termed a unit lock, which look is completely assembled before being mounted and then mounted in an opening cut through the edge of the door.
In Patent No. 2,304,612, issued to Henry G. Voight, on December 8, 1942, there is shown a lock system wherein the same basic parts may be employed for making a number of different locks, depending upon the use to which the desired lock is to be put. The simplest of the lock structures, of course, requires the fewest parts, and the more complicated structures are made by using those parts employed in the simplest lock and adding additional parts. In the present application, the same general principle is employed, but has been extended so that the resulting lock may, principally by choice of the proper escutcheon plates, be either a mortise lock or a unit lock. 'I'hat is to say, according to the teaching of the present invention, some six or eight differenttypes of locks may be made, and any of these may be either a mortise lock or unit look as desired.
One object of the present invention is to provide a lock structure from the parts of which a number of different locks may be made.
Still another object of the invention is to provide a lock structure having lock mechanism and a supporting case so arranged that the mecha- 4 Claims. (01.76-144) nism and case may be employed either in connection with a mortise lock or a so-called unit look.
A still further objectof the invention is to provide a lock having escutcheon plates and boltoperating means, such as knobs, rotatably mounted in the escutcheon plates, the latter bemg so connected to the lock case that perfect alignment of the knobs with the retracting mechanism inside the case will be assured.
To these and other ends the invention consists 'in the novel features and combinations of parts to be hereinafter described and claimed.

Fig. 14 is a. front elevational view of the lock case with the face plate removed and with the. outer escutcheon secured thereto. I
As illustrated in Fig. 1. of the drawings, I have shown a lock comprising a case I0 adapted. to be setin. a mortise in. the door H. The case l0 comprises a rear plate or base member I 2, and a cover. plate l3, these plates standing opposite each other, and the base or inner plate" I2 being provided withposts l4 having threadedsockets to receive screws passed through the cover plate to secure these two parts of the case together.
The case also comprises a front plate l5 which, as shown in Figs. G and '7, may be secured to the front and rear walls of. the case, so that-a lock with either abeveled face or straight face may be provided. ,In order to secure the-face plate I5 to the case, an attaching plate l6 provided with four lugs I! is secured to. the plate 12 by having one of the lugs I! passed through an opening in the plate l2 and then staked over to secure it in place. Another of the lugs His passed through an opening I8 in the face plate l5 and staked over, thussecuring, the face plate to the platel2. It will be understood that a similar plate I6 is provided at both topand bottom of the plate l2, and it will also be noted that, while one of the front and lower edges of the plate I! is cut off and extends at right angles to the plate 12, the'other edge extends at an angle to this plate. Therefore, when securing the plate Hi to the plate l2, it may be securedin either one of two reversed positions, so that the forwardedge of the plate I B may present either a straight face or an inclined surface, depending upon' whether or not a lock with a beveled face is desired. g
It'will be understood that the plate [6 is secured to the plate 12 prior to screwing the cover plate l3 thereto, and the latter is provided with an opening to receive another of the lugs l1, so that the front and rear plates and alsothe face plate IE will be rigidly secured together. In Fig. 6 of the drawings a lock with a beveled "face isillustrated, while in Fig. 7 of the drawings'the plate l6 hasbeen reversed end-for-end,
3 and the straight face thereof protects forwardly, thus providing a lock with a straight face.
A finishing plate l9 may be secured to the plate l by screws 20, this finishing plate concealing the openings IS in which the lugs l1 are staked and being only provided with the proper openings to permit the projection theret'hroug'h =cated openings in the lock case as will be hereinafter more .fully described.
The outer knob 50 is secured to a hollow 5| rotatably mounted in a sleeve 52, and sleeves of the parts of the lock which is being made.
Thus, in the present lock, the face plate 19 is provided only with openings for the bolt and the dogging means,
as will be hereinafter -de-' scribed, aside, of course, from the openings for i the screws 28. The rear of the lock case and the top and bottom thereof" between. the plates 12 and [3 may be closed by a U-shaped .sheet metal member 2! which acts only, however, as a cover or shield and plays no part in securing the other parts of the case together. 7
As shown in Fig. 5, the present lock is provided with a latch bolt 22 adapted to project from the front of the case, this bolt being actuated by a yoke or retractor 23 and urged to protracted position by a spring 24 acting against the bolt head and against a post 24 secured to the plate [2 of the case. Botatably. mounted within. the case are three rollbackhubs 25, 26 and 21 each of which is independently rotatable and each of which carries arms engageable with laterally or hollow posts 53 similar to the post 42 are secured to the outside escutcheon 54 by the plate 55.. the. inner end of the sleeve 52 being staked over this plate. The hollow shank 5| is secured in place by the split Washer 55, so that, with the exception of the fact that the knob shank is hollow, the construction of the outer escutcheon and knob assembly is substantially the same as that described in connection with the inside. Also, the knob shank is provided with a tenon 51 which is engaged in a recess or slot in the outer rollback 21.
Mounted in the outside knob is the usual keyoperated lock 59 having a key barrel 60 to the inner end of which is secured a spindle 6! extending loosely through the hollow shank 5i and non-rotatably engaged with the intermediate rollback hub 26,, so that operation of the key barrel bythe key will result in the retraction of the bolt when the outside rollback isdogged.
The particular type of lock shown in Figs. 1 to 5' is usually called a vestibule lock which is provided. only with a latch bolt and dogging mechanism to dog the latch bolt from operation by the outside knob, and key-operated means are provided in the outside knob to operate the bolt when the latter is dogged. The doggingmechanism may be of any of the usual types but, as herein shown, comprises a slide 32 operated from the facev of the door by stop buttons 33, the slide being provided with a. pin 34 adapted to enter an opening 35 in the outer rollback hub and thus dog this hub against movement.
The inner knob 36 is secured to a knob shank 31, this shank beingprovided with a tenon 38 upon its end designed to be received in a slot 39 of the inner rollback 25, so that the latter will be operated by rotation of the knob. It will also be noted that the knob shank is rotatably mounted in a sleeve 40 secured tothe inn-er escutcheon plate 4|, so that the knob .is supported by and rotatablymounted' on this plate. spacing sleeves 42. are also secured to this plate, these sleeves being secured in place by a plate 43 disposed adjacent the escutcheon plate 4! and secured thereto by the staking over of the inner end of .plate and extend inwardly. to be receivediu 9- 1 semblies are then put The walls of the lock case l2 and I3 areprovided with registering openings 63 and- 6'4 (Fig. 5.), which openings are adapted to receive the reduced ends of the sleeves 42. and 53 when the parts of the lock are assembled. In the mounting of the look upon ,a door, the lock case with its enclosed mechanism is inserted in a mortise made through, the edge of the door. The inner and outer knob and escutcheon plate asinto place, the sleeves 42 and 5.3 extending into theopenings 63 and 64 as shown in Fig. 3., which locates the escutcheon plates, knob shanks, and the spindle 6| accurately with respect-to the rollbacks 25, 25, and 21.
Screws 65. are inserted through the sleeves 42 and threaded into the sleeves 53, so that the escutcheons will be firmly secured to the lock case. and to the door. If the thickness of the door varies, it is only necessary to vary the lengths of thesleeves 42. and 53 and the screws 65.
. It will thusbe seen that while the knobs are carried by the .escutcheon plates, the knob shanks are. accurately positioned by means of engagement of the sleeves 42 and 53 with the lock case, so that there will beno and that there will be a perfect alignment of the rollback hubs on the one hand of the knob shanks and lock spindle. on the other hand. Moreover, the. :fact that the. knobs are carried by the escutcheon plates assures that the knobs will always stand at the same distance from the door,
regardle s of the thickness of the door which is not the case where: the knobs are carried by the lock case itself.
In Figs. 8 130 14 of the drawings, I have shown my invention as applied to a unit lock. The parts of thislock are, in the main, exactly similar to the parts already described, but changes are made in certain elements, owing to the fact that in a unit lock the e cutcheon plates are secured directly to the lock case, so that the lock may be applied as a unit instead-of in two or more parts as is the case with mortise locks. The lock case itself and the mechanism there n is the same as theirv previously described except that, as shown in Fig. 14, the front plate issomewhat shorter than the plate l5 being substantially the same length as the height of the lock ca e itself. Likewise, the face plate. or finish plate H is of the same length as the plate 10, butis provided with rearwardly directed flanges I2 and 13, so that the shank binding of the parts escutcheon plates 14 and flanges.
The inner and outer knobs 16 and 11 are assembled with the escutcheon plates as are the knobs 36 and 50, and the knob shank and spindle construction is like that previously described. Also retaining plates 18 and 19 are provided, the retaining plate 19 securing the sleeves 88 and BI to the inside escutcheon, while the retaining plate 18 secures sleeves 82 and 83 to the outside escutcheon, which sleeves are adapted to enter the openings 63 and 64 and locate the escutcheon relatively to the lock case.
Also, additional sleeves 84 and 85 are secured to the outside escutcheon by the retaining plate 18, these sleeves being adapted to receive screws 86 (only one of which is shown, Fig. 10) to secure the outside escutcheon to the case. It will be apparent that the escutcheon 14 is, therefore, firmly secured to the lock case, but that slight play is allowed between the inner escutcheon plate 15 and the lock case by the sleeves 88 and 8| to provide for any slight inequalities in the thickness of the door and to enable the escutcheons to be drawn up tightly to the door by the screws 81 and 88 passing through the sleeves 80, 8|, 82 and 83.
It will, of course, be understood that the screws 86 are put into position prior to the assembly in the lock mechanism in the case in the making of the unit lock. Likewise, the inside escutcheon i is provided with openings for screws 89 (Fig. to screw into the door to hold the lock in place.
In the usual and well-known manner of assembling a unit lock, the parts of the lock, including the escutcheon plate, are all assembled with the lock case and then placed in an opening in the door. With the present lock, it is only necessary then to tighten the screws 81 and 88 and insert the screws 89 to mount the lock in may overlap these place. Moreover, it will be seen that the same lock mechanism together with the case, with the exception of the front plate, is used in making both the mortise and the unit lock shown in the present application, and that in each case the escutcheons which carry the knobs are accurately located with respect to the case by sleeves secured to the escutcheons and received in openings in the walls of the case. By the use of the same parts for both types of locks, cost of manufacture is greatly reduced, and when to this is added the fact that with the same case and with the use of the same mechanism for the most part, many different types of locks may be made for uses upon doors in various locations, at great saving in expense in manufacture is eifected. Moreover, by reversing the plates l6, either a straight face or a, beveled face lock may be provided. In each case, the front face of the lock will be selected according to the openings desired in the face. That is, where both a dead bolt and a latch bolt are provided, for example, a face plate will be selected having openings for both bolts, whereas, in the present application, only one opening is provided, as the lock is provided with a latch bolt only.
While I have shown and described some preferred embodiments of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the claims.
