- I shall now proceed to a description of the extremely novel means through which I assemble the roses 11, 12 relatively to each other on the spindle housing 10.
- This sleeve 54 is, of course, adapted to be assembled on a cylindrical end portion 29 of the housing 10.
- the dogs 53 are formed with portions 55 that are disposed in slots in the sleeve 54 whereby the dogs are held relatively to the rose. Those edges of the portions 55 that face transversely to the axis of the sleeve 54 are tapered for reasons that will appear.
- the dogs 53 while held in the slots in the sleeve 54 can move radially of the rose 12, and are pressed inwardly by springs 56 so that the tapered portions 55 normally project past the slots into the central opening of the rose.
- the springs 56 are the opposed arms of a U-shaped wire spring 57 mounted on the rose 12.
- each dog enters a slot in one end portion 29 of the housing 10 in order to secure the rose 12 against axial movement. That the rose may be secured in either of two axially adjusted positions, I form axially spaced slots 58, 59 in pairs, as shown in Fig. 5. I have shown the slots 58, 59 of each pair as spaced angularly around the spindle axis as well as in an axial direction, but this angular spacing is not essential to my invention. At this point, it will be well to observe that I may form a pair of the slots 58, 59 in each end portion 29 of each housing part 26, 27.
- the slots 58, 59 are formed at predetermined locations in the spindle housing 10, it will be appreciated that, when assembled to the housing, the outer rose 12 is automatically located in a predetermined axial position relatively to the housing. Preferably, I so locate the slots 58 as to hold the rose 12 in the proper position to center the housing 10 in a particular thickness of door, and I then locate the slots 59 to act similarly for a thicker door. I have described the outer rose 12 as being held in either of two positions by the slots 58, 59 but it is of course within the province of my invention to form the slots in groups of three or more so that the rose can be secured in several positions upon the housmg.
- the dogs 53 can be caused to ride on their tapered portions 55 out of the slots 58 in the spindle housing by turning the rose 12 relatively to the housing portion 29.
- the rose 12 is then free to be adjusted to the position in which the dogs 53 enter the slots 59.
- the dogs 53 cannot be released when the loci: is assembled in the door because the rotation of the outer rose 12 is then prevented by the usual prongs as that engage the door, as may be seen in Fig. 1.
- the usual trim 61 on the rose covers the dogs 53 so that they cannot be tampered with.
- a spindle housing a rose having a surface to be applied against the face of a door and an opening in said surface adapted to receive a part of said housing, a dog on said rose extending into said opening, and said housing having spaced openings engaged selectively by said dog for assembling said rose in different adjusted positions relatively to said spindle housing.

LOCK CASE AND ROSE CONSTRUCTION Filed Oct. 14, 1952 3 Sheets-Sheet 5 INVENTOR ATTORNEY LOCK CASE AND RGSE CONSTRUCTIDN Daniel L. Biblin, Terryville, Conm, assignor to The Yale & Towne Manufacturing Company, Stamford, Calm, a corporation of Connecticut Application October 14, 1952, Serial No. 314,704 12 Claims. (Cl. 292337) This invention relates to the construction of a tubular lock and the means for securing it to a door. In locks of the particular class to which my invention relates, the lock parts are generally contained in two housings adapted to be assembled in two bores drilled in the door, one bore in the face of the door, the other in the edge. One housing, called the spindle housing, is mounted in the transverse bore formed through the face of the door, while the other housing, called the latch tube, is mounted in the other bore. On the ends of the spindle housing are inner and outer roses, and these roses or parts associated with them are utilized to secure the spindle housing to the door. The lock mechanism in this housing is then in operating position relatively to the bolt, which is in the latch tube.
By my novel lock construction, I am enabled to form the spindle housing so that two important parts are exact duplicates, and this in itself is an important feature of my invention. Of course, my invention is not limited to the use of duplicate parts, as parts that are merely complementary will suffice. These parts are formed from sheet metal and when made as duplicates provide the upper and lower halves of the spindle housing, the parts being coextensive along the spindle axis of the lock, with one part merely inverted relatively to the other. The
ends of the duplicate or complementary parts in assem- 1 bled position provide cylindrical end portions on which rotate the retractor tubes and knobs of the lock. As a particular means for holding the housing parts assembled, I may utilize ferrules on these cylindrical end portions. To prevent shifting of the parts of the spindle housing relatively to each other, I prefer to form interlocking means integrally on the edges of the parts.
Another feature of my invention resides in the particular construction whereby I mount a bolt retractor for movement in the spindle housing. Thus, I form each of the duplicate or complementary parts in the central portion of the spindle housing with a flat surface, and the bolt ret'ractor slides upon these surfaces. For further guiding the retractor, I utilize a pair of plates that are mounted transversely to the axis of the spindle housing, preferably by portions that enter openings in the duplicate or complementary parts of the housing. These plates engage directly the sides of the retractor, and also support the inner ends of the rotating retractor tubes. Further, as a particular feature of the central portion of the spindle housing, I form the duplicate or complementary parts with spring seats at one side of the housing for springs that press the bolt retractor, and with means at the other side of the housing for interlocking this housing with the inner end of the latch tube.
As another very important feature of my invention, I have contributed an extremely novel means to secure the outer rose adjustably upon the outer end of the spindle housing. In the prior art, coact'ing screw threads have been forn ed on the outer rose and the spindle housing for assembling these parts. I avoid the use of screw threads for this purpose while contributing definite predetermined adjusted positioning of the parts.
Upon my outer rose I mount preferably a pair of dogs, and these dogs interlock with the housing when the rose is applied to the housing. More in detail, each of the duplicate or complementary case parts has a pair of slots spaced axially of the spindle housing, and the dogs enter these slots selectively, preferably under pressure of yield ing means on the rose, so as to secure the outer rose in different axially adjusted positions. As a further part of this feature of the invention, I taper the portions of the dogs that enter the slots. Thus, when installing the lock it is possible to release the outer rose for adjustment to a different position merely by rotating the rose so that the dogs will ride on their tapered portions out of the slots in which they are located.
As a further feature, I utilize for securing the inner rose one of the transverse plates that guides the bolt retract'or. The portions of this plate that enter the openings in the spindle housing further extend outwardly of the spindle housing, and on each of these extended portions is a screw for securing the inner rose. Thus, by rotating the screws, the outer rose is drawn toward the inner rose through the transverse plate and the spindle housing, so as to clamp the door very securely relatively to this housing.
Those skilled in the art will appreciate that the locks of the particular class are adapted to be assembled either with or without a locking member for the outside knob, depending upon the type of lock that is desired. When the lock has such a locking member, it is generally a push piece that can be pressed at the inner side of the door to a locking position whereby to lock the outside retractor tube against rotation. In my novel lock housing, I utilize one of the transverse housing plates for coacting with the push piece so that the push piece will lock the retractor tube to the housing through that plate.
I have thus outlined rather broadly the more important features of my invention in order that the detailed description thereof that follows may be better understood, and in order that my contribution to the art may be better appreciated. There are, of course, additional features of my invention that will be described hereinafter and which will form the subject of the claims appended hereto. Those skilled in the art will appreciate that the conception on which my disclosure is based may readily be utilized as a. basis for the designing of other structures for carrying out the several purposes of my invention. it is important, therefore, that the claims be regarded as including such equivalent constructions as do not depart from the spirit and scope of my invention, in order to prevent the appropriation of my invention by those skilled in the art.
Referring now to the drawings, in which I show a preferred form of my novel lock construction, Fig. l is a section taken on a vertical plane along the axis of the spindle housing; Fig. 2 is a cross section on the line 2-2 of Fig. 1; Fig. 3 is a View similar to Fig. 7 but taken on a horizontal plane; Fig. 4 is a section on the line $-d of Fig. l, and Fig. 5 shows parts of the lock in exploded relation.
To facilitate a clear understanding of my invention, I shall describe first the general arrangement of the parts that corresponds to the arrangement usually found in looks of the particular class. Thus, in the form of my invention that I have illustrated, the spindle housing to is retained in the usual t ansverse bore in the door by roses l1 and 12, and inner and outer knobs 1.3, 14 rotate in the ends of the housing it) on retractor tubes 15, 16. The outer rose 12 determines the position of the spindle housing 1% relatively to the plane of the door and can be adjusted axially to enable this housing to be approximately centered in doors of diiferent thicknesses. After this adjustment has been made, the inner rose 11 is drawn toward the outer rose 12 on the housing It) so as to clamp the door between the two roses. Also, as is usual in locks of this class, the retractor tubes 15, 16 have cams 17, 18 through which they are adapted to move a bolt retractor 19 in the housing 10, and when so moved the retractor retracts a bolt 20 that slides in the latch tube 21 in the other bore in the door. One or more springs 22 are provided to move the retractor 19 away from retracted position. I have shown also a push piece 23 for locking the outer knob 14, this being quite customary in locks of this class. As shown in Fig. 3, the push piece 23 is pressed outwardly by a spring 24 and is dogged inwardly in locking position by the retractor 19 through a lug 25 on the push piece. The particular arrangement through which the push piece 23 is dogged is not important to my invention, however, and any suitable means may be used for the purpose.
In the general arrangement that I have described, I have now contributed an extremely novel construction in which I utilize to form the shell of the spindle housing complementary parts 26, 27 that may be seen in detail in Fig. 5. It will be understood that complementary housing parts have been used previously in looks of this class. In my invention, I so form the complementary parts 26, 27 as to coact in an extremely novel way with each other and with other parts of the lock. Also, because of particular features of my construction that will be described in due course, I am enabled to form the housing parts either partly or entirely as duplicates. As I have shown them in the drawings, the parts 26, 27 actually are duplicates. Merely by inversion endwise, one of these duplicate parts is in position to be assembled with the other, and the parts are then coextensive along the spindle axis.
Centrally of the spindle housing 10, the parts 26, 27 when assembled provide a relatively large and almost rectangular portion 28 in which the bolt retractor 19 moves. At opposite ends of the central portion 28, each of the housing parts 26, 27 is formed with a semi-cylindrical end portion 29, and these portions 29 together provide the spindle housing with cylindrical end portions upon which the inner and outer roses 11, 12 are adapted to be assembled. To secure the housing parts 26, 27 together, as shown in Fig. l, I prefer to employ ferrules 31) on the end portions 29. Actually, I form the extreme parts of the end portions 29 of a reduced diameter to provide sleeve portions 31 in which the knobs 13, 14 and retractor tubes 15, 16 rotate, and it is to these sleeve portions 31 that the ferrules 35! are applied. In order to hold the housing parts 26, 27 securely in registry when assembled, I prefer to form each of the semi-cylindrical end portions 29 at one side with a tongue 32, clearly shown in Fig. 5, that enters a groove 33 in the opposed housing part.
Returning now to the central portion 28 of the housing 10, it will be observed that I form in each of the housing parts 26, 27 a fiat surface 34, these surfaces lying in spaced planes parallel to the spindle axis when the parts are assembled. The bolt retractor 19 slides between the flat surfaces 34, and to guide the retractor during this movement, I provide a pair of parallel plates 35, 36 transverse to the spindle axis. Preferably, the transverse plates 35, 36 extend entirely across the interior of the central portion 28 of the housing, and to hold these plates in position, I prefer to form them integrally with opposed lugs 37, 38 that extend into identical slots 39 in both of the housing parts 26, 27.
It will be observed at this point that the bolt retractor 19 is of a generally rectangular form that is guided very easily by the flat surfaces 34 and the transverse plates 35, 36 although the particular construction of this retractor is not important to an understanding of my invention. As I have shown the retratcor 19 in Fig. 2, it includes a vertical wall 49 through which it is moved by the cams 17, 18 of the retractor tubes 15, 16. To coact with the tail 42 of the latchbolt 20, the retractor 19 has spaced parts 43 at its front end, as will be understood by those skilled in the art. It will be well to note that seats for the springs 22 are provided by identical lugs 41 that are turned inwardly from one edge of each of the spindle housing sections 26, 27, as will be seen in Figs. 2 and 5. Also, for assembling the spindle housing 10 to the latch tube 21, I form each of the housing parts 26, 27 with an inwardly turned portion 44, shown in Fig. 2. These edge portions 44 are at the opposite side of the central housing portion 23 from the spring seats 41, and are adapted to interlock in the usual way with retaining fingers 45 on the latch tube 21.
In addition to their function in guiding the bolt retractor 19, the transverse plates 35, 36 also serve to support the inner ends of the retractor tubes 15, 16. Thus, I form in each of the transverse plates a circular opening 45, best seen in Fig. 5, in which the tubes 15, 16 rotate. Also, when the lock includes the push piece 23, I utilize the plate 35 as the member to which the outer retractor tube 16 is locked by this push piece. For this purpose, I form the plate 36 with a groove 47 in which a tongue 48 on the push piece moves, as shown in Fig. 3. When the push piece 23 is in locking position, the tongue 48 extends into a slot 49 in the outer retractor tube 16 so that it effectively prevents rotation of the tube.
I prefer to utilize the customary spring pressed dogs 5%) for holding the inner and outer knobs 13, 14 assembled on the retractor tubes 15, 16. As I have shown these retractor tubes, the dogs 50 secure the shanks 51 of the knobs 13, 14 to the tubes within the sleeve portions 31 of the spindle housing, these sleeve portions having holes 52, Fig. 5, allowing access to the spring pressed dogs 59 so that these dogs can be depressed to permit removal of the knobs. In my invention, I prefer to form the access holes 52 for the dogs in identical locations in the housing parts 26, 27, as well shown in Fig. 5.
I shall now proceed to a description of the extremely novel means through which I assemble the roses 11, 12 relatively to each other on the spindle housing 10. I secure the outer rose 12 to this housing through a construction that utilizes a dog 53, best seen in Figs. 1 and 4, and by this construction, I facilitate the adjustment of the outer rose on the housing. In the preferred form of this construction, I mount a pair of the dogs 53 in opposed relation on a sleeve 54 that is formed on the outer rose 12 around the usual central opening. This sleeve 54 is, of course, adapted to be assembled on a cylindrical end portion 29 of the housing 10. The dogs 53 are formed with portions 55 that are disposed in slots in the sleeve 54 whereby the dogs are held relatively to the rose. Those edges of the portions 55 that face transversely to the axis of the sleeve 54 are tapered for reasons that will appear.
The dogs 53 while held in the slots in the sleeve 54 can move radially of the rose 12, and are pressed inwardly by springs 56 so that the tapered portions 55 normally project past the slots into the central opening of the rose. In the form that I have shown, the springs 56 are the opposed arms of a U-shaped wire spring 57 mounted on the rose 12.
As may be seen best in Figs. 1 and 4, the tapered portion 55 of each dog enters a slot in one end portion 29 of the housing 10 in order to secure the rose 12 against axial movement. That the rose may be secured in either of two axially adjusted positions, I form axially spaced slots 58, 59 in pairs, as shown in Fig. 5. I have shown the slots 58, 59 of each pair as spaced angularly around the spindle axis as well as in an axial direction, but this angular spacing is not essential to my invention. At this point, it will be well to observe that I may form a pair of the slots 58, 59 in each end portion 29 of each housing part 26, 27. By the particular formation of these slots, the end portions 29 are then identical and I am enabled to make the housing parts 26, 27 as exact duplicates. It will be understood, of course, that the outer rose 12 actually requires the slots 58, 59 only in the end of the housing on which this rose is assembled.
Because the slots 58, 59 are formed at predetermined locations in the spindle housing 10, it will be appreciated that, when assembled to the housing, the outer rose 12 is automatically located in a predetermined axial position relatively to the housing. Preferably, I so locate the slots 58 as to hold the rose 12 in the proper position to center the housing 10 in a particular thickness of door, and I then locate the slots 59 to act similarly for a thicker door. I have described the outer rose 12 as being held in either of two positions by the slots 58, 59 but it is of course within the province of my invention to form the slots in groups of three or more so that the rose can be secured in several positions upon the housmg.
I have already described the tapered shape of the portions 55 on the dogs 53. This particular formation contributes to the ease with which the outer rose 12 is adjusted on the spindle housing. Thus, referring particularly to Fig. 4, the dogs 53 can be caused to ride on their tapered portions 55 out of the slots 58 in the spindle housing by turning the rose 12 relatively to the housing portion 29. Of course, the rose 12 is then free to be adjusted to the position in which the dogs 53 enter the slots 59. The dogs 53 cannot be released when the loci: is assembled in the door because the rotation of the outer rose 12 is then prevented by the usual prongs as that engage the door, as may be seen in Fig. 1. Also, the usual trim 61 on the rose covers the dogs 53 so that they cannot be tampered with.
Referring now to the inner rose 11, I have shown in Fig. l the construction through which I assemble this rose on the spindle housing 10 so as to draw the outer rose 12 against the outer face of the door. I utilize for this purpose the transverse plate 35 that guides the bolt retractor 19 in the spindle housing. I form the tugs 37 on this plate 35 to extend outwardly of the spindie housing, and in the inner rose 11 are screws 62 that are threaded into the lugs 37. When the screws 62 are tightened, the transverse plate 35 does, of course, draw both of the housing parts 26, 27 axially so as to hold the outer rose 12 in firm engagement with the outer face of the door. To conceal the screws 62, I provide the usual trim 63 that is snapped over the inner rose 11.
I believe that the novel construction and operation of my lock will be clearly understood from my description, and that its novel advantages will be fully appreciated by those skilled in the art.
