No. 44,655 Claims. '(Cl. 70156) My invention relates to a two-way locking device whereby a door is locked at its top and bottom by abar mounted for vertical movement in the lock stile of a door, and is preferably adapted to be key actuated for both locking and unlocking a door, although, other means may be employed if desired.

Another and further object of my invention is' the provision of a two-way locking deviceadapted-for'use with a free swinging door opening in one direction only, which door is usually unlatched and'may be either opened or closed by some form of power actuated device for normal operation and thereafter locked in closed position through theme of akey and also unlocked with a key from either side of the door.

-Another and further object of my invention is the provision of a two-way lockingdevice applied toa-door and available for'useif desired; but in which thedoor is normally operated without the use-of a locking mechanism and actuatedby some form of door closing mechanism, such as a spring or torsion bar actuated device, and when out of use may be locked by means of a key so that the dooropening is closed; t 6

Another and further object of my invention is the pro vision of atwo-way locking arrangement which is neat in appearance andconcealed inthe locking stile ofthe door in such position that it-is easily. put into operation but is out ofthewayifor normal operatio-nof the-door and does not interfere in any manner whatsover with the operation of. the door.

These and other objects of my invention will be better and more fully understood by reference to the accompanying drawings andin whicl1.-

FIGUREZ is a vertical sectional view on lines 2'2 ofFIGUREl; v FIGURE 3 is a cross sectional view on lines 3-3 of FIGURE 1; v m

FIGURE 4 is a vertical'view partially in elevation and partially. in section on lines 4,4 of FIGURE 3; z

9 FIGURE 5 is avertical sectional view showing thelock holding mechanism anddoor locking cylinders in locked position; and

FIGURE 6 is a cross sectional view on lines 6-6 of FIGURE4. p Referring now specifically to the drawings, and in which like, reference characters refer tolike-parts throughout; a floor 10 is shown with a wall 11 anda door frame desig nated asa whole as 12 mounted in the wall 11, the frame 12 consisting of a side member 13 having ayverticalrib 14 which acts as ,a door stop, a second side member 15, a header 16 which extends across the top of the door opening and which connects each of the side members 13 and together, and a threshold 17which spans the door opening at the bottom thereof. A door designatedas a whole as 18 isprovided which consists of a lock stile 19, a hinge stile 20, a top rail 21 and a bottom rail 22, with the top and bottom rails 21 and 22 being secured to the stiles 19 and 20 at each of their ends forming a complete door frame, A panel 23 ofglass, wood, or the like, is mounted in the door 18 forming a closure therefor while hinges 214, 24 are provided by means of which the door 18 is mounted in the door frame 12 in the usual manner.

The lock stile 19 is a hollow rectangular member hava door and door 3,086,383 Patented Apr. 23, 1963 2 ing front and rear side walls 25 and 26, an inner wall 27, a web 28, which is positioned inward fromthe outer edgesof the Walls 25 and 26 a short distance, and an astrical 29 which is secured tothe Web 28 by screws and fitted betweenlthe side walls 25 and 26 at their forward edges which extend-beyond the web 28,;with the inturned flanges on the a'strical' 29 being fitted against the web-28 thereby forming a complete closure member of the lock stile 19. A "portion of the web 28 is-removed to provide space iii-the lock stile 19 to receive a locking cage 30', which is fitted in the lock stile 19 in the space formed by the cut-out ofthe web 28 and consists of a U-shaped channel section having a base wall 31 and spaced side sections 32 and 33 at each side thereof for the entire length of the locking cage 30 and have extensions 34 and 35 integrally formed therewith which are spaced apart from each other the same-distance as are the portions 32 and 33 to form the lower portion of the locking cage 30. The side sections 32 and 33 have web portions 36 and 37 integrally formed therewith with wing portions 38 and 39 thereon which are-conneoted b-y webportions 36 and 37 to the spaced side sections 32 and 33, with the wing portions 38 and 39' having flanges 40 and 41 thereon at their outeredges which are fitted'intorecesses formed in the astrical 29 so the locking cage 30' is held in position.

A pair of externally threaded locking cylinders 42 and 43 are provided which extend through openings in the side walls 25 and 26 of the lock stile 19, and through threaded openings in the wing portions 38 and 39 of the locking cage 30, with locking rings 44, '44 in threaded engagement with the locking cylinders 42 and 43 at their outer ends, and which serve to hold the locking cylinders in position in the door stile 19, with the inner ends of the locking cylinders 42 and 43 being spaced apart for purposes hereinafter described. The locking cylinders 42 and 43 are held in position by screws 42*, 42 which extend through the flanges '40 and 41 and into channels in the sides of the locking cylinders. Key cylinders 45 and 45 are mounted in and extend through the locking cylinders 42an-d 43, which key cylinders are rotatable within the locking cylinders 42 and 43. Each key cylinder has a key opening 46 in the outer end for the receipt of a key. The key cylinders 45 and 45 have cams in their inner spaced ends with lugs 47 and 47 thereon for actuating the locking and unlocking mechanism as hereinafter described.

A look bar 48 is slidably'mou'nted in the locking cage 30 between the side sections 32 and 33 of this member, and extends throughout the entire length of the locking member 30, and has arod 49 connected to its upper end which extends through a guide 50 secured to the inner Wall 27 of the locking stile 19. The rod 49 is curved at its upper end and has a locking bolt 51 mounted thereon at its outer end which extends through a bracket 52 secured by means of a screw 53 to the web 28 in the lock stile 19. The locking bolt 51 terminates adjacent the upper end of the lock stile 19 and is adapted to fit into an opening 54 in the door frame header 16 when the door is in locked position.

A compression spring 55 is provided which is mounte upon the rod 49 and has its upper end in abutting engagement with the fixed guide 50, and its lower end in engagement with the upper end of the locking bar 48, with the spring 55 being compressed at all times and exerting its force downward on the locking bar 48 which has a pin 56 .mounted therein which said pin 56 extends into slots 57, 57 in the sections 32 and33 of the locking cage 30 and which acts as a stop to the downward movement of. the-locking bar '48. A cut-out 58 isprovided in the locking bar'48 with an upper shoulder 59 thereon, with a projection 60 extending outward from the locking bar 48 and which is adapted to be engaged by a latch 61 pivotally mounted upon a pin 62 extending through the wing portions 36 and 37 of the locking cage 30. The latch 61 has a shoulder 63 formed thereon for the purpose of engaging the under side of the projection 60 on the locking bar 47 and seats in a recess formed in the side of the locking bar 48 which recess substantially conforms to the side contour of the latch to hold the door in locked position as will be hereinafter described. The latch 61 also has a projection 64 thereon with a spring 65 being provided which is pivotally mounted upon a pin 66 with the spring 65 being coiled around the pin 66 and having a right angled turned end in engagement with the edge of the wing 35 and the opposite end of the spring 65 in engagement with the latch 61 so as to force the latch 61 to rotate normally in a clockwise direction about the pin 66 and keeps the latch 61 in engagement with the locking bar 48.

The locking bar 48 has a series of rack teeth 67 located at one edge thereof at its lower end which are engaged by a gear wheel 68 located upon a pin 69 mounted in the extensions 34 and 35 of the side sections 32 and 33 of the locking cage 30. The gear wheel 68 engages with a toothed rack bar 70 mounted in the lower end of the locking cage 30 between the side extensions 34 and 35 of the side sections 32 and 33. The rack bar 70 is connected to a rod 71 and has a pin 72 extending therethrough into slots 73, 73 formed in the side extensions 34 and 35 of the side sections 32 and 33 of the locking cage 30. The rod 71 has a locking bolt 74 mounted on the lower end thereof which extends through a fixed bracket 75 secured to the web 28 of the door stile 19 by means of a screw 76, with the end of the locking bolt 74 terminating adjacent the lower edge of the lock stile 19 and opposite an opening 77 formed in the threshold 17 for receiving the locking bolt 74 when the door is in locked position.

The operation of the device is exceedingly simple in that the parts as hereinabove described and shown are in open position of the door, in which position the locking bolts 51 and 74 are held in unlocked position, or withdrawn from the threshold and header locking keepers by the spring 55, which pushes the locking bar 48 downward to the limit of its travel as defined by the pin 56 thereby pulling the rod 51 downward to unlocked position. The movement downward of the bar 48 rotates the gear wheel 68 in a clockwise direction, which lifts the rod 71 withdrawing the locking bolt 74 from the opening in the threshold 17 thereby completely unlocking the door. When it is desired to lock the door in its closed position, the operator, if outside the door, by inserting a key in the key opening in the *key cylinder 45 rotates the said key cylinder 45 in a counter-clockwise direction, as shown in FIGURES 4 and 5, the lug 47 on the key cylinder engages the shoulder 59 on the locking bar '48 thereby lifting the locking bar 48 against the compression spring 55 and forcing the locking bolt 51 into engagement in the opening 54 in the top door frame member. As this movement is accomplished the travel of the locking bar 48 upward rotates the gear wheel 68 in a counterclockwise direction which drives the rack 70 downward and forces the locking bolt 74 into the opening 77 for engagement with the threshold 17. With the door in locked position the latch 61 is rotated in a clockwise direction by the spring 61 forcing the shoulder 63 on the latch 61 under the projection 64) on the locking bar 48 which holds the door in locked position until released. If the operator wishes to unlock the door from the outside a key is placed in the key cylinder 45 and the key cylinder rotated in a clockwise direction (FIGURES 4 and until the lug 47 in the key cylinder 45 engages the projection 64 on the latch 61 and by continued turning of the key the latch 61 is moved out of engagement with the shoulder 60 on the locking bar '48, the spring 55 forces the locking bar 48 downward thereby releasing 4 the bolt 51 at the top of the door and lifting the bolt 71 out of engagement with the threshold.

If the key is inserted into the key cylinder 45*- from the opposite side of the door for opening the door the key is turned in a clockwise direction, which rotates the lug 47 into engagement with the shoulder 59 on the locking bar 48 and lifts the locking bar 48 which results in the locking bolts 51 and 74 being forced into the openings 54 and 77 and into locking position of the door. As the locking bar 48 is raised, the latch 61 engages the projection 60 on the locking bar 48 which holds the locking bolts 51 and 74 in position in the keepers at each of their ends and the door is held in locked position.

When it is desired to unlock the door from the rear side the operator inserts a key into the key cylinder 45 and rotates the cylinder 45' in a clockwise direction thereby moving the lug 47 into engagement with the projection 64 on the latch 61 which moves the latch 61 out of engagement with the shoulder 63 on the locking bar 48 in which position the spring 55 moves the locking bar 48 downward releasing the locking bolt 51 at the upper end of the door and at the same time through the rack and pinion connection at the bottom of the locking cage 30 lifts the locking bolt 74 out of its engaged position in the threshold so that the door is released and free to be opened and closed by either mechanical or hand actuating means.

If desired the usual pintle and doorknob combination can be inserted into the locking cylinders 42 and 43 and the locking bar 48 and the latch 61 actuated by this combination in precisely the same manner as is done with the key cylinders 45 and 45 While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of the invention.
