WALTER R. SCHLAGE, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO SOHLAGE LOCK 00., SAN- FRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA.
DOOR LOCK.
Application filed August 20, 1923. Serial No. 658,245.
This invention relates to door latches and especially to a double unit latch, together with means for assembling, connecting and securing the same in a door.
The object of the present invention is to generally improve and simplify the construction of door latches to permit saving both in time and cost of installation; to provide a latch which consists of two separable units, to-wit, a knob actuated retracting unit and a latching unit, each unit being enclosed by an independent housing and each unit being self-contained; to provide a latch of this character in which means are employed for interlocking the housings and the contained mechanisms when they are assembled in a door, and further to provide a latch of this character in which lateral adjustment is permitted between the indi- .vidual housings and the contained mechanisms, thereby permitting the latch to be fitted to doors of variousthicknesses. Other objects will hereinafter appear.
One form which my invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which:
Fig. 1 is a perspective view of the unit which carries the latch actuating mecha' nism. a 3
Fig. 2 is a perspective view of the unit which carries the latch mechanism.
Fig. 3 is a perspective View of a portipn of a door showing the manner in which it is drilled to receive the respective units.
Fig. 4 is a cross-section of the latch showing the latch actuating unit and the latching unit assembled and interlocked.
- ig. 5 is a perspective view of one of the spindle sections.
Referring to the drawings in detail, and particularly to Figs. 1, 2 and 4, A indicates in general a housing which contains a latch actuating mechanism and B a housing which reception of the housing B; the respective.
contains a latch mechanism. Each housing holes 2 and 3 being best illustrated in Fig. 3, these holes being drilled with an ordinary brace and bit and as such require comparatively little time when comparison is made with the cutting and mortising of doors for 80 the reception of ordinary latches. The housing A, as previously stated, contains the latch actuating or retracting mechanism and it also forms a support for the spindles 4 and 5, which carry knobs not here illustrated.
The latch retracting mechanism consists of a rigid rectangular shaped frame consisting of upper and lower guides 6 and 7 suitably secured interior of the housing A. Slidably mountedbetween these upper andv lower guides is a latch retracting member 8. A spring 9 is interposed between a lug 10 and a lug 11 and this spring serves the normal function of projecting the retracting member 8. The spindles are provided with retracting lugs as indicated at 12, the upper and lower portions thereof engaging the members 11 and 13 of the retracting member 8, that is, turning movement may be transmitted. to the spindles in either direction and this turning movement retracts the member 8. For instance, if the spindle is turned in the direction of arrow a, the upper part of the lug 12 engages the lug 11 and 35 thereby retracts the member 8. the spindle is turned in the direction of Again, if
arrow 6, the lower part of the lug 12 engages the lug 13 and the member 8 is again 7 retracted. It therefore makes no difference whether the spindle is turned in one direc -tion or another as retracting movement is, imparted in either instance and an auto-- matic return movement is imparted by the spring 9. 1
The latch mechanism, as previously stated, consists of the housing B. This housing carries a keeper plate 14, a latch 15 and a. latch actuating plate 16. The inner end of the housing B is closed by an end plate 17 and a spring 18 interposed between this end plate and the inner end of the latch 15 serves the function of normally projecting the latch. The springs 9 and 18 cooperate and actin unison and the size and 105 tension of the springs may thus be reduced to a considerable extent, or either might break without materially afiecting the operation of the mechanism.
Themain feature of the present'invention is that part of the structure whichpermits interlocking of the housings A and B and simultaneous lnterlocking of the retracting member 8 and the latch actuating plate 16. For the purpose of interlocking the housings removal of the housing B is prevented. To
interlock the retracting member 8 and the latch actuating plate 16,'a pair of lugs is formed on'the inner end of the latch actuating plate as indicated at 24:. These lugs are engaged by a pair of fingers and 26 which form a part of the retracting member 8 and an interlock is thus formed-between the retracting member and the latch actuating plate which permits these to cooperate.
and function in unison;
. By referring to Fig. 1 it will be noted that the slot 19 is extended a considerable distance and, similarly, that the fingers 25 and 26 have a length substantially equal thereto.
This is of great importance as it permlts lateral adjustment of the housings with relation toeach other and also lateral adjustment of the mechanisms contained in the respective housings; that is, the lugs 24 formed on the inner end of the latching plate so inserted itwill be noted that the lugs may slide along the fingers 25 and 26 and as long as. ngagement is maintained between the lugs 1 and the fingers 25 tion is permitted. It should be remembered desirable to place the latch in the center of the door as shown in Fig. 3- Such disposition of the latch, or, in other words, the housing B with contained mechanism, is permitted in this instance as the length of the slot 19 and the fingers 25 and 26 is such that operative engagement is maintained .throughout a considerable range.
In actual operation if it is desired to apply a latch to a door, it is only necessary to take an ordinary brace and bit and first drill an opening transversely through the door as indicated at 2, and then to drill a hole at right angles theretoas indicated at 3, care being taken of course to center and align the openings before drilling the same. After this has been accomplished, the keeper plate 14 which carries the housing B is next inserted endwise in the opening 3 and when 23 and 24 project slightly into the transverse opening 2. The housing A is next inserted endwise through the transverse opening 2 in the direction of arrow 0 (see Fig. 3) and.
and 26 operaof the door may vary extent as engagement when so inserted an interlock will be automatically formed between the lugs 23 and 24, the flanges 21 and 22, and the fingers 25 and 26; that is,.the flanges 21 and 22 will pass over the lugs 23 and the fingers 25 and 26 will at the same time pass over the lugs 24. The two units of the latch indicated at A and B are thus assembled and interlocked and it is then only necessary to secure the unit A against removal by applying a clamping plate such as indicated at C (see Fig. 1) This plate engagesthe face of the door indicated at D, while an annular flange 30 on the opposite end of the housing engages the opposite face of the door indicated at E, the flange 3O limiting the endwise movement of the housing A when inserted in the direction.of arrow 0 and the clamping plate Oserving the function of securing the housing against removal; that is, a pair of screws is passed through openings 31 in the clamping plate and the openings 32 formed in the housing. The inner ends of the screws there engage threaded lugs formed on the retractor guide as shown in my eopending application entitled Door lock, Serial No. 656,335, filed August 8, 1923. The clamping plate and the housing A is thus drawn tightly together and secured in the opening 2 and the whole operation is completed by applying the knobs to the ends. of the spindles indicated at 4:, and 5 and securing them in any suitable manner. A pair of screws is finally inserted through the keeper plate 14 and the striker plate is placed in position on the door frame in the usual manner, thus completing the operation of installing and assembling the latch.
By referring to Fig. 1 it will be noted that the housing A'is provided with a bearing extension 33 and that this is fairly long. The clamping plate C is slidably mounted on this bearing extension and as such is adjustable to the inner end of the housing A. This feature is of importance as it permits the'latch to be installed in doors of various thicknesses and correct positioning of the housings A and B is at the same time taken care of as. considerable lateral movement between the housing A and the housing B is permitted due to the length of the slot 19 and the flanges'21 and 22. In other words, the. interlock between the housings and the mechanisms contained therein is not disturbed even though the thickness to a considerable is maintained between the flanges 21 and 22 and the lugs 23 throughout the entire length of the slot 19 and engagement is similarly maintained 125 between the lugs 24: and the fingers 25 and 26 throughout a considerable range of movement.'
A divided spindle is employed in this instance and the inner end of each spindle 1 is therefore provided with a retracting lug as indicated at 12, thus permitting indivldi al operation of each knob and spindle.
mechanisms contained therein, and a strucill turc which permits lateral adjustment between the same. It is for this reason that no particular stress has been laid on the latch actuating or retracting mechanism, etc., and furthermore for the reason that this specific structure forms the subject matter of a copending application entitled door latch. filed August 8, 1923, Serial No. 656.335.
