DOOR OR WINDOW ADJUSTER.

Specification of Letters Patent."

Patented J an. 119, 1915.

Application filed March 13, 1914. Serial No. 824,418.

To all whom it may concern Be-it known that I, CARL JOHN HAGSTROM, asubject of the King of Sweden, and a resident of Glen Cove, in the county of Nassau and State of New York, have invented a new and Improved Door or Window Adjuster, of which the following is a full, clear, and exact description.

This invention relates to builders hardware and has particular reference to appliances for doors, French windows or the like, whereby means are provided to secure or adjust the door in any desired position.

Among the objects of the invention, therefore, is to provide for a door hand controlled means of a simple and reliable nature to automatically lock or secure the door in any desired position to which it may be swung on its hinges, such means, however, being automatically released by the turning of the usual knob or its equivalent.

' The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a plan view of a door equipped I with one embodiment of this invention, the door frame being shown in section; Fig. 2 is a detail plan view of that portion of the top ofthe door remote from the hinge; Fig. 3 is a vertical section of the same on the line 3-8; Fig. 4 is a view corresponding somewhat to Fig. 3 but omitting the door structure; Fig. 5 is a view of the latch mechanism and including a continuation of the structure shown in Fig. at; Fig. 6 is a vertical transverse section on the line 6-6 of Fig. 2; Fig. 7 is a detail plan view of the portion of the door remote from that shown in Fig. 2; Fig. 8 is a fragmentary side elevation of a door showing certain slight modifications; Fig. 9 is a vertical section on the line 99 of Fig. 10 indicating certain modifications and additions of mechanism; Fig. 10 is a view at right angles to Fig. 9, partly in section on the line 1010; Fig. 11 is a top view of a door, partly broken away, indicating a modified form oflocking bar; Figs. 12 and 13 are views in two positions of the trigger mechanism for the locking bar; Fig. 13 is a view corresponding to Fig. 13 but indicating in dotted lines a modified structure; Fig. 1% is a view corresponding to the upper portion of Fig. 8 but showing a further modification; Fig. 15 is a transverse section on the line 1515 of Fig. 1d; and Fig. 16 is an enlarged view of certain details shown in Figs. 14 and 15. r

The several parts of the device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed.

At 20 I show a door of any suitable construction, and for the'purposes of this invention the term door will be understood as being'applicable to any device, in the nature of a door, window or the like, to which this invention may be applied. Said door is shown hinged at 21 to a door casing or frame 22. Associated with the door at any desired place, either at the top or side, is a stay rod 23 pivoted at 24.- to the door frame or any other fixed support and having its outer end pivoted at to a block 26 slidable along the door toward or from the axis of the hinge 21. The block 26 operates in a dovetail groove 2'? shown in Fig. 6 as formed in a fixed plate 28 at the top of the door having a fixed shoulder 29, and opposite said shoulder is a locking bar 30. At 31 I show a strip or plate acting as a keeper or guide for the locking bar, the bar being movable both longitudinally and laterally beneath the keeper. The bar 30 has a beveled edge opposite the shoulder 29 and when the bar is forced toward said shoulder it will grip the block 26 and hold it in definite position, thereby fixing the effective length of the stay, holding the door in the position in which it is placed at the time the block is gripped. As shown in Fig. 2, the door is provided with a series of cam faces 32 ar-. ranged preferably parallel to one another and coiiperating with roller cams 33 respectively. Said cams 33 have fixed position in or adjacent the plate 28. l Vhen the looking bar 30 is drawn toward the hinge 21 as, for instance, by means of a strong spring 34, the cams 33 acting through the cam faces 32 will force the locking bar laterally into gripping engagement with the block 26. When, however, the locking bar is moved longitudinally in the opposite direction or against the tension of the spring 32, as by means of a bell crank 35, the effect of the cams is neutralized and the lock 26 is allowed to be loose for free slidable movement in the groove 27, allowing the door 20 there fore to be swung upon its hinges.

The bell crank 35 is shown preferably pivoted at 36 at the top of the door, and is provided with a hook 37 cooperating with a lip 38 at the outer end of the locking bar. The opposite end 39 of the bell. crank is shown connected to a draw bar at) associated with the latch mechanism shown in Fig. 5 as including a tumbler 41 adapted to be rotated in any usual manner and coiiperating with a lever 42. Vi hen the tumbler is rotated by the operator and the lever and bar thrown downwardly, the locking bar 30 is drawn against the tension of the spring 34: releasing the block. vVhen, however, the tumbler s1 is allowed to assume its normal position under the action of the spring d3, the looking spring automatically acts to lock the block 26.

The arrangement in Fig. 8 is not materiallydifferent from that above described except that the block 26 is arranged on the side of the door and the locking bar 30 is constructed for operation in a vertical plane instead of a horizontal plane. The latch mechanism in this form of the invention is slightly different in that it provides a means for locking the parts in free position; that is to say, the tumbler 4-1 is provided with a connection 4% at the lower end of the draw bar 40 whereby said draw bar, upon turning the knob in one direction, will be so swung as to bring the point of connection to or beyond the dead center, whereby the upward pull upon the bar 40 due to the spring 3 1- will be resisted by the position of the tumbler and the connection 44. The locking bar, therefore,will be held in such position as to allow the block 26 to have free slidable movement. Upon turning the knob, however, in the other direction, setting the draw bar 10* free, the block 26 will. be locked in the manner above described.

That form of the invention shown in Figs. 9 to 13 shows its adaptation to a door having a knob or handle 45 and a tumbler 41 having connections et6 with a locking bolt 4:7 adapted to cooperate in any usual or well known manner with the top of the door frame to lock or hold the door closed inclependently of my improved mechanism. The knob 45 is shown held in normal position by means of a spring 48 arranged in the mortise lock 49. In this form of the invention the locking bar 30 is adapted to be withdrawn from looking position by means of a hook 37 pivotally connected to a bell crank 35* pivoted at 36 on a fixed bracket 50 constituting a part of the socket member 51 in which the bolt 47 operates under the tension of a spring 52. Upon rotation of theknob or handle 45 in the direction of the arrow of Fig. 9, the bolt at? will be retracted and in so doing will bear downwardly upon the point 39 of the bell crank with the result th'atthe locking bar will be drawn out of locking position. The bell crank carries a stud 53 which is adapted to snap under a catch 5% formed on a sort of rock shaft shown in cross section in Figs. 12 and 13, and the position of which is indicated in dotted lines in Fig. 9. To the outer end of the rockshaft 55 is secured an arm 56 having a finger 57 which limitsthe upward swing thereof under the force of the spring 58; that is to say, when the bolt 47' inclined face 55' of the rock shaft. bringing the stud into the position shown in Fig.

and since the finger 57 is adapted to strike against the fixed casing at the top of the door, the catch will hold the bell crank in the position just indicated, and hence the bar 30 will be held out of locking position 7 until the stud 53 is released.

Any suitable means may be provided to rotate the rock shaft in the direction of the arrows in Figs. 12 and 13, whereby the stud 53 and member carrying it are released, allowing the locking bar toautomatically lock or grip the block 26 in the manner previously set forth. The means I show herein for the purpose just set forth includes a push button 58 at the edge of the door, the inner end of the push button bearing against a bell crank 59 pivoted at 60 and to the other end of which is connected a link 61' leading to the free end of the'arm 56. When the knob is turned, therefore, to open the door, the trigger mechanism of Figs. 12 and 13 will lock the locking bar inoperative, and if it is desired to secure the door ajar in any desired position, the operator has but to press the button 58, making the locking bar operative again automatically.

Fig. '11 shows a plate member 28 provided with one or more plates 33 secured thereto and taking the place of the rollers 33 above described, but otherwise the operation is the same as already set forth.

Fig. 13 shows the rock shaft 55 provided with an arm 56 extending from'the side of its axis and adapted to be pushed upwardly by a bar 61 for the purpose of'releasing the stud 53 and thebell crank 39 Figs. lto 16 show a modification of locking bar 30 of similar form cooperating with a bar 28 of similar form, there being provided between the two members a succession of cams 33 which have the same function as the rollers and plates above described;

otherwise the arrangement is substantially against the locking bar on its lower edge.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, in a device of the character set forth, of a grooved plate, a block slidable in said groove, a locking bar cooperating with said block, a stay rod pivotally connected at one end to the center of said block and to a fixed point at the other end, and means to automatically cause the locking bar to grip the block in connection with said plate whereby the stay serves to secure the door in any desired position.

2. In a device of the character set forth, the combination-of a plate having a dovetail fgroove, a block slidable in said groove, a stay rod pivotally connected to said block, a locking member cooperating with said grooved plate and said block, means to antomatically cause the locking member to grip the block and bind it in fixed position in said groove, and means to draw the locking bar out of gripping position against the force of said automatic means.

3. In a device of the character set forth, the combination of a grooved member, a block slidable in the groove of said member, a stay rod pivoted at one end to. the block and at its other end to a fixed point, a looking bar separate from and cooperating with the block, automatic means acting on said locking bar to cause it to move longitudinally and laterally to grip the block in fixed position, and a bell crank member acting upon another part of the bar to withdraw it out of locking position and against the fort) of said automatic means.

4. The combination with a door, of a grooved plate secured thereto and extending toward the hinge of the door, a block slidable in the groove of said plate, a locking bar cooperating with said member and block, means connected to the locking bar to automatically cause it to move longitudinally and laterally with respect to the block to cause the block to be gripped in definite position, a door knob, and connections between the door knob and another part of the locking bar to cause it to be withdrawn from looking position, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CARL JOHN HAGSTROM.
