LOCK-ACTUATING MECHANISM.

Specification of Letters Patent.

Patented Nov. so, 1915.

Application filed. April 30, 1914. Serial 11033552 1.v

To all whom it may concern:

Be it known that I, GEORGE Angeles, in the county of Los Angeles and State of California, have invented certain.

new and useful Improvements in Lock-Actuating Mechanism, of which the following is a specification.

My invention relates to locking mecha nism and particularly to mechanism for throw ng a plurality of bolts in different d1 rections, this mechanism being particularly adapted for use with the form of combined door and window shown in my pending application Serial No. 807,527, filed on' the 18th day of Dec, 1913. In this application for patent there is illustrated an improved form of window which also may be used as a doorand in which the window (or door) is provided with pintles on opposite sides which are adapted to be projected into the window casing so that the window may be side, as may either from the right side or left be desired. In this prior application these pintles were shownas being opened detachable and shiftable from one side of the window casing to the other. In this application there is also shown a locking device whereby the window might .be locked in the casing.

One object of my invention is the provision' of locking means adapted particularly for use in connection Withthe above de-, scribed window, so constructed as to con trol the operation of pivotbolts or pintles on opposite sides of a window or door and so control the operation of bolts whereby" the door or window may be locked tothe window casing, it being understood, however, that the pivot bolts or pintles them-' selves act as looking bolts under certain circumstances.

A further object of the invention is to so construct the locking mechanism above referred to,'that it may be applied toa large variety of structures and usedfor throwing or retracting a plurality of bolts.

Still another object of the invention is to so construct the locking mechanism, above referred to, that two actuating devices or keys must be used to completely retract all of the bolts, one of these locking devices A. FAIR, citi zen of the United States, residing at Los actuating the longitudinally movable bolts which orm the pintles' or. pivot bolts when the device is used for a window or door and theother controlling the latching bolt.

- A further object of the invention is .to

simplify loc'lring'mechanism of the character described, reduce its cost, render it easy 1 of operation and reduce liability of the parts getting out of order.

Other ob ects will appear in the course of the following description.

Myinvention is illustrated in the accoma pan ying drawings wherein V igure 1 is a iront elevation of a piv oted window of the easement type, the sashframe being shown partly in section so as to sl owrthe-bolt mechanism within the sashiframe.

Corresponding and like parts are referred to: in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

'Before describing the detailed construction of the locking mechanism, I will first describe one of the structures to which the locking mechanism is peculiarly adapted, this beingthe window structure illustrated and describedin detailin my pending application for patent above referred to.

V In Fig. 1 is' illustrated a window, the frame of this window including the Vertically disposed members 3 within which b possible to project the pintles 13 and 14 on there is mounted an exterior sash-frame comprising hollow side bars 4, illustrated in detail in Fig. 2. The outer faces of these side bars 4 are formed .by curved plates 5 which are illustrated as hinged at 6 so as to open when desired to permit the insersash-frame within which the sliding sashes are mounted is of the easement type and is, therefore, pivotally connected tothe frame of the window. To this end the window frame includes theuppen and lower transverse members 10 and 11, the upper and lower plates respectively, of which, are formed with sockets 12 for the inserion of pintles 13 and 1 1. The plate 5 is also perforated at 15 for the passage of laterally projectable bolts which engage with the face of the window casing 2.; With the construction of window illustratedin Fig. 1 it is one side of the window so that the window will. be pivoted upon that side and retract the pintles on the other side of the window so that this side of the window may be free to move. If it be desired for any reason that the window shall open in a reverse direction, then the first named set of pintles are withdrawn from engagement with the window casing and the second named set of pintles is projected. It is-for the purpose of providing means for withdrawing these pintles and also withdrawing the latching bolts which engage the side members of the window casing that I have provided mechanism illustrated in Figs. 2, 3, i and 5, it being one of the objects of nay-invention to so construct this mechanism that the means for projecting or retracting the pintle bolts 13 and let will be independently operable from the mechanism for projecting the latching bolts. The mechanism for this purpose is most clearly shown in Figs. 4 and 5. For the support of the bolt actuating device the plate 5 is formed on opposite sides with the inwardly projecting annular bearings 16 and 17, respectively. Mounted within the annular bearing 16 is an annular sleeve 17 the outerend of which extends-out through the front of the casing and is formed with a knob 18 whereby the sleeve may be rotated. The sleeve at its innerend is countersunk asat19 and disposed within this countersink is a barrel 20 illustrated in detail in Fig. 5. Disposed within the barrel 20 is a shaft 21, the endsof which are formed with longitudinally extending relatively short nal axis.

kerfs or grooves 22 and 22''. This shaft has a length equal to the barrel 20. The extremity of the barrel 20 projects slightly into a thinible 23 which is rotatably mounted within the bearing member 17, the inner end of this thimble being outwardly flared as at 2%. It will thus be seen that the barrel 20 is mounted for rotation around its longitudinal axis and that the shaft 21 is also mounted for rotation around its longitudi- The barrel 20 is longitudinally slotted at diametrically opposite points at both ends as at 25 and 26 and at its middle.

is formed with an arcuate slot 27 which alineswith a screw threaded perforation 28 formed in the shaft 21.

A screw 29 extends through the sleeve 17 and engages the adjacent end of the barrel 20 so that the sleeve 17 and the barrel 20 rotate together. Mount-ed upon the barrel 20 is a, collar 30.. This collar is provided with a slot 31 through which a screw 32 passeswhich enters the slot 27 and engages the perforation 28 in the shaft 21. The collar 30 has a tubular extension 33 projecting tangentially from one side and into which the slot 31 opens and mounted in this tubular extension 33 isa latching bolt 3 1. The pin 32 which is carried by the shaft 21 projects through the slot 27 of the barrel 20 and the slot 31 of the collar 30 and is connected to the bolt 34 by means of a link 35 and disposed within the extension 33 between the bolt 31 and a stop 36 is a coil .JDPlDL 37 which normally tends to project t e bolt. It will be obvious now that a rotation of the shaft 21 in a counter-clockwise direction in Fig. 3 will cause a retraction of thebolt'3at against the action of the spring 37, the collar 30 remaining stationary.

Mounted upon the collar 30 and extending over the slot 31 is an arcuate spring 38, the extremity of which is formed with a detent tooth This tooth is adapted to engage over the head of the screw 32, as illustrated in Fig. 3, when the shaft 21 is rotated so as to retract the bolt. The spring 38 is of sufficient strength to hold the bolt 34 retracted when the parts are in the position shown in Fig. 3, but yet not prevent the proper manipulation of the bolt to project it. It will be seen that when thebolt is projected the detent 39 will engage behind the head of the screw 38 and thus resist the inward movement of the bolt. The spring 38 is held to the collar 30 by means of a screw 10 extending into the perforation 41 formed in the collar 30. The extremity of the extension 33 is intended to be engaged with the perforations 15 in the plate 5 through which the bolt is projected, as illustrated in Fig. 3, and this extension merely acts as a guide for the bolt.

For the purpose of operating the pintle bolts 13 and 1 1 I mount upon'the barrel 20 the collar 42 illustrated in detail in Fig. 5 this collar being held in place on the barrel 20 by means of a set screw 43 or in any other suitable manner. The collar 42 is providedat opposite points in its middle with pairs of arms 43 between which the inner ends of the pintle bolts 13 and Id are pivotally supported, as illustrated clearly in Fig. 2. It will be obvious now that a rotation of the barrel 20 in one direction through the action of the knob 18 will withdraw the pintle bolts from their projected position and that a rotation of the knob 18 in the other direction will act to project the pintle bolts. I

Mounted upon thecollar 42, asillustrated in Fig. 2 is a spring detent 426, the extremity of which is formed with a slightly depressed portion adapted to engage with shallow re-' cesses l7 and 48 formed in the bearings 17.

,This spring 436 forms a tooth holding the collar set in either of its rotated positions. For the purpose of operating the shaft 21 I dispose within the bore of the knob 18 and the sleeve 17 a spindle L9, 'he'eXtremit-y of which is provided with a. small knurled knob 50. The inner end of this-spindle 49' is formed withoppositely disposed teeth 51 projecting longitudinally of. the spindle, which teeth are adapted to engage in the groves 22 formed atone end of the shaft 21.

As before stated the barrel 20 is provided at one 'end with slots 26 and atthe opposite end. withslots 25. This permits the barrel 2Q andthe shaftQl to be operated from the exterior by means of keys A and B, as shown in Fig. 4; Key A is formed with the relatively widely spaced longitudinallyextend ing. teeth a. which are, adapted to engage with the notches 25.

of such width as to engage the'grooves 22 By inserting the key A, therefore, the barrel 20 may be rotated to thereby retract or project the pintle bolts, and by inserting the key, B the shaft 21 may be rotated to thereby project or retract the latching bolt 3i.

As seen in Fig. 2 there is a locking mechanism of the character heretofore described at each side of the window engaging with the adjacent casing wall. In one of these locking devices the pintles are projected so as to form a pivot forthe window while the latching bolt 3a. is normally retracted. At the opposite side of the window, that is, the side edge which is free, the pintle bolts are normally retracted and the latching bolt 34: only projected when the window is closed to hold the window shut. 1

As before stated, I primarily design my mechanism for use with the window illustrated in Fig. 1, where it may be desired to The key B is provided with the teeth 5 whichare so positioned and change the pivotal center of the window from one side to the other. In this case it is only necessary to removea screw 52 which passes through a slot 53 formed in the bearing 16 and which also passes through'a slot- 54 formed in the sleeve 1'? and which engages With the spindle i9, thus holding the spindle in place and also holding the sleeve 17 in place and preventing any pulling out of the sleeve or spindle. By removing this bolt 52 the sleeve l'i niay be withdrawn, as may also the spindle a9 and sleeve may then be shifted from one of the locking devices to the other, thus practically rendering one of the locking devices inoperative and the other operative. It will of course beobvious that the knob 18' and the spindle 49 are to be disposed on the free or movable side of the window, there beingno knob upon the locking mechanisnron the,

other side of the window which will prevent accidental tampering with the pintles or with the latching mechanism; If it. be desired, however, to withdraw the pintles,

upon the pivot side of the window so as to permit the window to be taken out, for 'instance, or if it be desired to throwthe latching bolt. on the pivotside of the window, then thelshait 21 and barrel 20 on that side of the window may be operated by means of keys of thestype shown in Fig. 4 and lettered A and B. If it be desired to loc the win dow particularly securely, it is obvious that rior ofthe compartments l that I hinge the plate 5.

In Figs. 6 and? I show my invention as applied to door and I wish it distinctly'understood that while I have shownit used on a house door, the invention may equally well be applied to doors of any construction, such as doors of vaults, safe deposit boxes,

door and D the door-frame. As illustrated, thesill and 'lintel of the door are provided with sockets 12 of precisely. the same form of the sockets 12, heretofore described. j The dooris recessed to receive the locking mechanism which is the same as that described,

7 or like. structures. In these figures C designates the this locking mechanism being providedwith j the vertically extending pintle bolts 13? and li 'The locking mechanism is controlled by" knobs and keys in precisely the sameman- -l neras shown in Figs. 2, and it, and has exactly the same construction;

In order topermit the door to be rotated it can be set in a slightly deep recess and rotated flat against the wall and I form the sockets 12" arcuate, as illustrated clearly in Fig. 6 so that when the door swings into the dotted line position shown in Fig. 6, the pintles 13 and 14 on that side of the door will travel through the arcuate slot and thus permit the door to be shifted flat against the wall. It will be seen that the arcuate slot l2 on the free side of the door does not prevent the pintle bolts from acting to lock the door when they are projected.

In Fig. 8 I show a modification of the construction shown in Fig. 4 in which the outer barrel is adapted to project the latching bolt while the inner shaft is adapted to project the pintle bolt, this inner shaft being entirely key actuated so as to prevent any accidental throwing of the pintle bolts. In this form of the device the plate 5 is provided on 0pposite sides with inwardly projecting bearings l6 and 17, as previously described. Disposed within the bearing 16 is the sleeve which has formed with it the knob 56 where by the sleeve may be manually rotated. Disposed within the innerend of this sleeve 55 is thebarrel 57 to which the sleeve is fastened by means of the set screw 58 so that the barrel rotates with the sleeve. Stir-- rounding the barrel is the collar 59 which has the same form as the collar 30, previously described, and operating through the slot 60 in this collar is the pin 61' which corresponds in every respect to the pin 32, previously stated, except that it is fastened on the barrel and not upon the central shaft. This pin 61 is operatively connected to the bolt 62, as shown in Fig. 11, so that a rotation of the handle 56, the sleeve 55 and the barrel 60 will cause a projection or a retraction of the bolt. Also mounted upon the 1 sleeve 57 is the collar 63 which corresponds to the collar l2 and is operatively connected to the upwardly and downwardly extending pintle rods 13 and lt, in the same manner as is the collar 4:2; For the purpose of operating this collar 63 and thereby throwing the pintle rods in or out of operative position, the collar is connected to the central shaft 64 by means of the pin 65 which passes through the slot 66 formed in the collar 63.

The shaft 64 has exactly the same form as the shaft 21 and is notched at its ends as at 67 for engagement by a key. A thimble 68 is disposed within the bearing 17 and supports the forward end of the sleeve 57. It will be obvious now, that upon a rotation of the shaft 64: thepintle bolts will be retracted or projected and that upon a' rotation of the sleeve 57 thelatching bolt will be projected or retracted. The latter is accomplished by rotating the knob 56 but rotation of the shaft 64: can only be accomplished by. means of a key such as the key 13 in Fig. 4 having lugs Z) which will engage the notches 67 on the ends of the shaft. Thus, while the latching bolt may be manually projected or re tracted the pintle bolts cannot be actuated except through the use of a key.

In Figs. 9 and 10 I show my invention as applied to a safe deposit box or like structure. In these figures 69 designates the wall of a safe deposit vault and 70 designates the box which is slidable into the compartment 71 and out from said compartment. This box has a front wall 72 and an intermediate wall 73 and a rear door 74 which can only be opened when the box is withdrawn. The box is held within the compartment 71 by means of vertically extending bolts 75 and 76 and the laterally projectable latching bolts 77. The operating mechanism for these bolts 75, 76 and 77 is designated generally 78 and is of exactly the same construction as the operating mechanism illustrated in Figs. 2, 3 and t except that the mechanism is made to be operated entirely by keys in the manner shown in the right hand side of'lTig. 4 and is not operated by knobs. The bolts and the bolt operating mechanism are all contained in the space between the front wall 7 2 and the intermediate wall 73. In this case it will be noticed that the members 75 and 76 both operate as looking bolts and not as pintle bolts and that two keys are necessary to operate the bolt throwing mechanism, one key operating the laterally projecting bolt and the other operating the vertically projected bolts. It will be obvious that a set of four keys, may be used so as tooperate these bolts, one pair for each of the locking mechanisms, the keys being different so that thus an additional security is provided.

It will be seen from what has gone before that while I have designed my operating mechanism primarily for use with the door or window for the purpose of throwing or retracting pintle bolts and latching bolts, yet it may be largely adapted for a number of other purposes andit is for this reason that I have illustratedthe applicationof my device to a safe deposit box where the box is entirely withdrawable from the bolt. The same locking means, however, may be used upon a hinged door, if desired.

Vhile I have illustrated what I believe to be the best form of my invention Ido not wish to be limited to the detailsof construction as it is obvious that many changes might be made without departing from the spirit of invention.

It will be seen that I have provided a lock which is also a hinge so constructed that by the use'of two of these hinge locks the pivotal' point of the door may be shifted from one side to the other, if desired. Further, it will be seen, that when in use, and when both of the locking or bolt-operating mechanisins are used the door is held at siX points.

Further, that I provide a door locking and hinging construction requiring the use of two keys and operating members in order to secure a complete operation of the mechanism. This gives eXtra security to all buildings and at the same time permits of the window or door being swung from either side. The lock or hinge is concealedwithin the door itself, nothing but the keyhole or the knob whereby the device is operated being visible from the outside.

One of the principal features of my invention lies in the fact that the door or window can be unhinged in a moment so that the whole door may be removed without the necessity of taking off the hinges. This permits the ready removal of the door to allow furniture, pianos, or like bulky objects to be moved through the doorway.

A further advantage of the construction lies in the fact that when all of the bolts are shut the door is shut tight at every point. This keeps the doors from warping inwardly at the upper and lower corners above the usual lock. Again it must be reiterated that while I have illustrated my invention as applied to a door or window or safe deposit boX, that it is not limited to this application, as it may be used for safety doors, for boxes, trunks, lockers, or in many other situations.
