23 Claims. (Cl. 292-244) This invention relates to latches and more particularly to latches adapted to be employed in doors. The invention comprises improvements in latches which enhance their utility and increase their adaptability.
-ln the design of structures employing doorways with doors mounted at the doorways for movement between open and closed positions it has been customary to completely design the structure even as to the side of the doorway at which the door is to be mounted and the` direction in which the door is to swing or slide toward closed position and parts adapted specifically for the particular installation as designed have been specified. How. ever, there are occasions when it is desired to postpone determination as to just how doors are to be mounted relatively to their respective doorways until near completion of the structure. This is especially true in respect of industrial structures such as Shop partitions and the like. It may be diicult to determine at the time of designing a shop partition just how each door should 'be mounted, i. e., whether it should be a slidingdoor or a swinging door, if a sliding door toward which side of the doorway lit should open and if a swinging door to which side of the doorway it should be hinged and in which direction it should swing when being opened. Yet heretofore it has been considered necessary to initially cornpletely design the structure even to the type of each door and the relationship to the doorway in which the door is mounted. This has made it difiicult or impossible to mount doors differently than in accordance with the original design whenY near completion of the structureit appears that the original design was not in all respects desirable insofar as the types of doors selected and the relationship to their respective doorways in which they were designed toy be mounted are concerned.
l have devised a latch which is universally adaptable for sliding and swinging doors, for right-hand and lefthandy doors and.` for doors which if of the swinging type swing either inwardly or outwardly. Use of my latch makes -it possible to postpone until near completion of a structure determination of the question as to how each door is to be hung yet without incurring delay in obtaining special latches when the determination has been made.
Other details, objects and advantages of the invention will become apparent as the following description of a present preferred embodiment thereof proceeds.
In the accompanying drawings I have shown a present preferred embodiment of the invention in which:

Figure; 12 is a face view of one of the two opposed casing members; and
Figure 13 is an end View of the casing member shown in Figure 12 as viewed from the right in that figure.
The latch casing is designated generally by reference numeral 2 and comprises two identical opposed casing members 2a and 2b. Figures 12 and 13 show the structure of the casing member 2a and since the casing members 2a and 2b are identical Figures 12 and 13 also s how the structure of the casing member 2b. Each of such casing members is made out of sheet or plate metal and comprises a generally planar body portion 3 of generally elongated rectangular shape having at each end adjacent each longitudinal edge a flange integral with the body portion and turned at right angles thereto. Thus there are fou-r suchflanges on each casing member. The flanges at one end of the casing member are of the same shape as each other and the flanges at the opposite end of the casing member are of the same shape as each other and of the same shape as the anges at the first mentioned end except for an added projection to which reference will be made below whose purpose is to provide an anchor for a coil spring biasing the bolt. The flanges at one en d of the casing member are designated 4, each being of generally rectangular shape but having a circular hole 5 therethrough and having a recess 6 in the edge thereof which forms a continuation of the corresponding longitudinal edge of the body portion 3. The ilanges at the other end of the casing member are designated 4 and are identical with the flanges 4 except that each ange 4 has an added projection 7 projecting into the recess thereof which corresponds to the recess 6 of each of the anges 4. The function of each of the projections 7 is to provide an anchor for a coil spring biasing the bolt as will appear below.
Each of the casing members 2a and 2b has a pair of longitudinal parallel slots 8 in each end thereof extending parallel to the longitudinal edges of the casing member and providing therebetween a tongue 9. Bach of the tongues 9 is integral with the body portion but is deformed out of the plane of the body portion and is itself generally planar and lies in a plane generally parallel to the plane of the body portion disposed at the side of the body portion toward which the llanges 4 and 4 project. Each tongue 9 has two circular holes 10 therethrough.
Each of the casing members 2a and 2b has formed, therein closer to one of its ends than to the other end a circular depression 11 and through the depression 11 is formed an opening 12 of generally elongated shape with straight sides 13 extending generally parallel to the short dimension of the casing member and curved ends 14 joining the straight sides as clearly shown in Figure 12.
In assembling the casing the two identical casing members 2a and 2b are disposed with their flanges 4 and 4 toward each other and with the openings 12 in nonopposed relation. This results in the flanges 4 of each of the casing members being opposed to the flanges 4' of the other casing member. The casing members are brought together so that the flanges of one overlap the flanges of the other and they are fastened together by bolts passing through the holes 5 of the overlapped flanges and having nuts 16 applied thereto. Thus there is formed by the use solely of two identical casing members, four bolts and four nuts a latch casing which has an inner space for containing the latch bolt and bolt operating mechanism and an opening at each end (formed between the opposed faces of the respective tongues 9 and between the inner edges of the respective flanges 4 and 4') so that the bolt may have its operative end projecting selectively through either end of the4 casing. There is applied to the end of the casing through which the operative end of the bolt projects a plate 17 which is an elongated rectangular plate of sheet or plate metal having through the center thereof a rectangular opening 18 through which the operative end of the bolt is adapted to extend and also having therethrough an inner pair of bolt holes 19 and an outer pair of bolt holes 20. The inner pair of bolt holes 19 have the same spacing as the holes 5 of the casing members 2a and 2b. When the casing members 2a and 2b are assembled the bolts 15 which hold them together at one end also pass through the bolt holes 19 of the plate 17 and thus attach and hold in place to the casing the plate 17. When the casing members 2a and 2b and the plate 17 are assembled the anges 4 and 4' of the casing members are so disposed relatively to each other that the plate 17 lies against the flanges 4 of one of the casing members. When the casing members are assembled the anges 4 having the added projections 7 are disposed toward the inside of the casing relatively to the flanges 4. The bolt holes 20 are for bolting the latch to the door to which it is to be applied. When the latch is applied to the door it is inserted into a suitable recess provided in the door with the plate 17 disposed at the edge of the door and extending beyond the recess so that attaching bolts passing through the bolt holes 20 also pass through a portion of the door to hold the latch in place relatively to the door. Screws instead of bolts may be used for fastening the latch to the door.
The latch bolt is shown in perspective in Figure 1l. It is designated generally by reference numeral 21 and comprises a body 22 having latching portions 23 and 24 respectively connected therewith and projecting therefrom in opposite directions. The latching portions 23 and 24 are of different construction and are selectively usable as the operative portion of the bolt depending upon whether the bolt is mounted in the casing for sliding movement or for swinging movement. When the bolt is mounted in the casing for sliding movement the latching portion 23 is the operative portion of the bolt. When the bolt is mounted in the casing for swinging movement the latching portion 24 is the operative portion of the bolt. The bolt is mounted in the casing for sliding movement when the latch is used in a swinging or hinged door and the bolt is mounted in the casing for swinging movement when the latch is used in a sliding door. The latching portion 23 has an inclined end face 25 which when the bolt is disposed in generally horizontal position is oriented substantially vertically, which is characteristic of sliding bolts used in swinging doors. The inclined end face 25 is adapted to engage a portion of the door frame when the door is swung shut, such engagement resulting in camming back the bolt until the door reaches fully closed position when the bolt is projected by its spring behind the portion of the frame referred to to maintain the door closed. The latching portion 24 has an inclined end face 26 which when the bolt is disposed in generally horizontal position is oriented at an angle to the vertical, which is characteristic of swinging bolts used in sliding doors. The inclined end face 26 is adapted to engage a portion of the door frame when the door is slid shut, such engagement resulting in tilting the bolt until the door reaches fully closed position when the bolt is swung down either by its spring or by gravity or both so that the hook por- 4 tion 27 thereof lies behind the portion of the frame referred to to maintain the door closed.
Through the body portion 22 of the bolt are two openings 28 and 29 respectively. The openings 28 and 29 are separated from each other by a rib 30 through which passes a pin 31 projecting at both faces of the bolt as shown in Figure l1. Considering the bolt to be oriented horizontally and disposed in a generally vertical plane as indicated in Figure 1l, a pin 32 integral with the bolt is disposed at the edge of the bolt above the pin 31 and a pin 33 integral with the bolt is disposed at the edge of the bolt below the pin 31, the pin 32 projecting past only one face of the bolt while the pin 33 projects past only the opposite face of the bolt. At the edge of the bolt at which the pin 32 is disposed and positioned so that the pin 32 lies therebetween are pins 34 and 35 integral with the bolt which project past only the face of the bolt opposite the face past which the pin 32 projects. At the edge of the bolt at which the pin 33 is disposed and positioned so that the pin 33 lies therebetween are pins 36 and 37 integral with the bolt which project past only the face of the bolt opposite the face past which the pin 33 projects. Thus the pins 31, 32, 36 and 37 project past one face of the bolt while the pins 31, 33, 34 and 35 project past the opposite face of the bolt. All of the pins project substantially the same distance beyond the respective faces of the bolt. The total length of the pin 31 is slightly less than the distance between the inner faces of the body portions 3 of the casing members 2a and 2b when they are assembled as above described. The thickness of the body portion 22 and the latching portions 23 and 24 of the bolt in the direction parallel to the axes of the pins is slightly less than the distance between the inner faces of the opposed tongues 9 of the casing members. Thus the bolt is by the pins which are disposed between the inner faces of the body portions 3 of the casing members 2a and 2b and the latching portions 23 and 24 which are disposed between the opposed tongues 9 maintained generally in operative orientation within the casing. The bolt 21 may be cast, in which case the pins 31, 32, 33, 34, 35, 36 and 37 may be cast integral therewith.
The bolt is adapted to be operated by either of two identical cams 38 of sheet or plate metal, the cams 38 having the shape shown in Figures 6, 7, 8 and 9. Each thereof has a projection 38a extending in one direction and a projection 38b extending in the opposite direction, the projection 38b having opposed operating corner portions 38e and 38d respectively. Each cam 38 has generally centrally located a generally keyhole-shaped cutout 38e. The respective cams 38 are positioned within the casing so that one thereof lies against one face of the bolt and the other thereof lies against the other face of the bolt.
There is mounted in each of the openings 12 a cylinder lock case 39 having the usual provision for lock tumblers and the usual cylindrical bore 40 into which a bolt operating device may be inserted. The bolt operating device may be a lock cylinder or it may be a device other than a lock cylinder such as the knob 41 having a reduced cylindrical shank 42 rotatably received within the bore 40. When the bolt operating device is a lock cylinder the cylinder and the case 39 are provided with the usual tumblers so that the cylinder may be turned only by the use of a key shaped to operate the tumblers to permit turning of the cylinder as well known to those skilled in the lock art.
As will be understood from what is stated above, it is optional whether provision be made to operate the bolt by a lock cylinder or operating means other than a lock cylinder from either side of the door. Lock cylinders may be used at both sides of the door or operating devices other than lock cylinders may be used at both sides of the door or a lock cylinder may be used at one side of the door and a device other than a lock cylinder at the opposite side of the door. In the draw- I ings the knojb 4.1 which requires no key for its operation isl used, at. one side of the door and a lock cylinder 43 which requires a key for its operation is used at the other side; of the-door.
Referring to Figure l0, a camY turning device 44 cooperates with the knob 41;. The cam turning device 44 comprises a. generally plate-like portion 45 of generally keyhole shape and a generally cylindrical portion 46 integral therewith and projecting in one direction therefrom, the portion 46v being adapted to have an operating t, within the bore 40 ofv the case 39 with which the knob 41 is used.. The portion 46 of the cam turning device 44 enters. the bore 40 from the inside of the case. In the extremity of the portion 46 are two intersecting cross slots 47 adapted selectively to receive a projection 4.8; at the inner end of the shank 42 of the knob 41 so that when the cam turning device 44 is applied to the bore 40 from the inside of the case and the knob 41 ifs applied to the bore 40 from the outside of the case the knob will, be operatively connected with the cam a turning deviceto turn the same when the knob is turned. Ilhel projection 48 of the knob enters only one of the cross slots 47 of the device 44. When a round knob is. used it is immaterial which cross slot the projection 43V enters. lever type knob or handle may be used and the orientation of the lever will be determined by which of the slots in the carn turning device the projection at the inner endV of the lever shank enters. If it is desired that the, lever be normally oriented in generally horizontal position the projection will enter one slot while if it is desired that the lever be normally oriented in generally vertical position the projection enters the other slot.
'llhel knob 41 has therethrough a bore 49 enlarged adjacent the outer end of the knob as indicated at 50. The cam turning device 44 has a threaded bore 5l. When the parts have been assembledas4 above described so that the projection 48 of the knob enters one of the cross slots 47 of the cam turning device 44 a screw 52 `is introduced through the bore 49 and threaded into the bore 51 to maintain the knob 4,1 and the device 44 assembled, the head 53 of the screw being concealed within the enlarged outer portion 50 of the bore. The portion 45 of the cam turning device 44 isl as above rnentioned of generally keyhole shape and is adapted to snugly enter the cutout 38e of one of the cams 38. A similar generally keyhole-shaped plate is applied to the inner end of the lock cylinder 43, as by being screwed or otherwise fastened in non-rotativelrelation thereto, and is adapted to snugly enter the cutout 38e of the other cam 38. Each of the cases 39 has an outer circular flange 54 substantially filling the circular depression` 11 of the casing member to which it is applied and the body of the case is: shaped to snugly fit within the opening 12 and isfmantained in place by a nut 55 threaded. onto the inner end thereof and turned up against the inner face of the casing at the depression 11. The conforming non-circular shape of the opening 12 and the portion of the case 39 passing therethrough holds the case against turning relatively to the lock casing 2.
Each of the bolt operating devices passes through one of the openings 28 and 29 of the bolt 21, the accessible portion thereof (the knob 41 or lock cylinder 43 as the case may be) being vat one face of the casing 2while the camy 38 operated thereby is at the opposite face of the casing. In other words, each of the bolt operating devices operates through one of the openings of the bolt and acts on the bolt at the face thereof remote from the face of the casing at which the external force for operating the bolt is applied. Each of the cams 38 lies between one of the side faces of the bolt and the inside ofthe lock casing and is operatively connected with the keyhole-shaped carn turning device to which it is applied by fitting its keyhole-shapedy cutout about the cam turning device; In other words, there is no need of pro- However, instead of using a round knob a 6 viding` any fastening means for the cams 38' since they are confined between the bolt and; the respective inside. faces of the casing 2 so| that. they cannot losetheir oper ative connection with the respectivecam turning devices without disassembling the casing.
The bolt 21 is supported in the casing by the nutsl 55 which lie within the openings 2S and 29, respectively, of the bolt. Normally the surfaces definingV the tops of the openings 28 and 29 of the bolt ride upon the toprnost surfaces of the nuts` 55. When the bolt is mounted as a sliding bolt it is supported by the nuts 55 at virtually all times. When the bolt is mounted as a swinging or tilting bolt it is supported by the nuts 55 when in operative position. Actually it is also supported by the pin 57; in the structure shown when the bolt when mounted as a swinging bolt is in operative position as shown in Figure 8 it is supported by the pin 57 and also by the two nuts 55. When the bolt is swung or tilted to inoperative position as shown in Figure 9 it rises out of Contact with the nutsA 55.
A tension coil spring 56 is applied between the bolt and the casing, having one end anchored to one of the pins of the bolt and the other end anchored to one of the projections 7 of the casing to normally urge the bolt toward operative position.
The parts may be assembled to provide a latch having a sliding latch` bolt for a door hinged from either edge and swinging either inwardly or outwardly or latch having a swinging or tilting latch bolt for a sliding door. Figures l--7 and l0 show a latch having a sliding latch bolt while Figures 8 and 9 show a latch having a swinging or tilting latch bolt. ln the form of Figures l.7 and l() the latching portion 23 projects through the plate 17' and the bolt is biased' toward operative position by anchoring the spring 56 between the pin 37 and the projection 7 at the iower front corner of the casing (the front of the casing being consideredl as the end at which the plate 17 is applied which is disposed at the edge of the door). A pin 57 passes through the upper opposed holes it) at the rear of the casing. The pin 57 is not always essential when the bolt is mounted for sliding movement and may in some instances be dispensed with. However, it restrains any tendency which the rear end (i.e., the lefthand end viewing Figures 6 and 7) of the bolt may have to rise during operation of the latch as the upper surface 58 of the portion 24 rides substantially against or very close to the bottom of the pin as the bolt moves back and forth. The pin is provided. for use when the bolt ismounted as a swinging or tilting bolt as will presently appear and it is recommended that it be applied as shown in Figures 6 and 7 when the bolt is mounted as a sliding bolt although the latch may be operative if the pin is not so employed.
With reference to Figures 6 and 7, the bolt may be retracted by either of the cams 38. The left-hand cam 38 viewing Figures 6 and 7 is disposed at the face of the face of the bolt nearer the eye, that being the face of the bolt from which the pin 36 projects. When the left-hand cam 315 is turned in the clockwise direction viewing Figures 6 and 7 the portion 38C thereof engages the pin 36 and retracts the bolt. The right-hand cam 38 viewing Figures 6 and 7 is disposed at the face of the bolt remote from the eye and when it is turned in the counterclockwise direction the portion 38aoperates against thepin 3S to retract the bolt. When no force is being exerted against the bolt to retract it or hold it in retracted position spring 56 returns it to operative position.
Referring now to Figures 8 and 9, the bolt is shown in those figures as being mounted for swinging or tilting movement. A circular hole S9 is provided in the portion 230i the bolt and the pin S7 is inserted through the hole 59 and the-lower opposed holes-10 at the rear of the casing as shown in'Figur'es 8i and 9, the portion 24 of the bolt projecting through the plate 17. Thus the pin 57 holds the bolt against translatory movement in the casing but permits turning of the bolt about the pin as an axis. The spring 56 is anchored between the pin 37 and the projection 7 at the lower rear corner otthe casing and tends to turn the bolt in the clockwise direction about the pivot pin 57, i. e., so as to draw downwardly the portion 24 of the bolt. The bolt may be turned in the counterclockwise direction viewing Figures 8 and 9 about the pivot pin 57 by either of the cams 38. For thus turning the bolt the pin 31 is utiltized. When the left-cam 38 viewing Figures 8 and 9 is turned in the counterclockwise direction the portion 38d thereof engages beneath and forces upwardly the pin 31, thus swinging the bolt about the pivot pin 57 to raise the portion 24 thereof. Similarly when the right-hand cam 38 viewing Figures 8 and 9 is turned in the clockwise direction the portion 38d thereof engages beneath and forces upwardly the pin 31, thus swinging the bolt about the pivot pin 57 to raise the portion 24 thereof.
It will be understood that when closing the door it is unnecessary to operate the bolt except through the action thereon of the portion of the door frame (normally a strike plate attached to the door frame) which acts against the inclined face 25 or 26 of the bolt, depending upon whether the bolt is being used as a sliding bolt in a swinging door or as a swinging bolt in a sliding door, and after the door has closed the spring 56 will move the bolt to operative position to maintain the door closed until the bolt is retracted by one or the other of the bolt operating devices. Retraction of the swinging bolt means turning of it in the counterclockwise direction viewing Figures 8 and 9 about the pivot pin 57 so as to raise the hook portion 27 to a level above that of the cooperating portion of the strike plate.
