DOOR ANYD WINDOW ADJUSTER.

Specification of Letters Patent.

Patented Aug. 9, 1921;.

Application filed June 4,1920. Serial No. 386,584..

To all whom it may concern 7 Be it known that I, Enonn R. SUBROYAR, a subject of the King of Great Britain, residing at Shanti Bhavan, Brodies Road, Mylapore, Madras, India, have invented certain new and useful Improvements in Door and Window Adjusters, of which the following is a specification.

This invention relates to improvements in door and window adjusters.

An important object of the invention is to provide a device by means of which a door or window may be secured in any desired position.

A further object is to provide a device of the above character which is readily combinable with door locks of the usual type.

Other objects and advantages of the invention will become apparent throughout the course of the following description.

In the accompanying drawings, wherein for the purpose of illustration are shown preferred embodiments of my invention. and wherein like numerals designate like parts throughout,

Figure 1 is a side elevation of a doorhaving my invention applied thereto,

Fig. 2 is an enlarged fragmental side elevation thereof,

Fig. 3 is an enlarged section taken on the line 33 of Fig. 2,

Fig.4 is a section taken on the line 1-4; of Fig. 1,

Fig. 5 is a combined perspective of the parts of my invention separated,

Fig. 6 is a side elevation of my device attached to a window which opens outwardly,

Fig. 7 is a section taken on the line 77 of Fig. 6, s

Fig. 8 is a section taken on the line 8-8 of Fig. 6, showing the open position of the window in dotted lines,

Fig. 9 is a sectional view showing my device combined with a mortise lock, and,

Fig. 10 is a sectional view showing my device combined with a rim lock.

Referring now more particularly to the drawings, the numeral 10 indicates a rod, pivotally connected at one end to a bracket 11 secured to the frame 12 of the door. It will be understood that where the invention is applied to a window, the bracket 11 will be secured to the wall adjacent the window or door to which the invention is applied instead of the framing.

The free end of the rod 10 is pivotally connected to a slidable bar 141, which bar operates n a suitable guide 15 secured to the door or window. This guide may be of any de sired construction, that in the present instance being shown as a bar with longitudinal portions 16 at its edges, which overlap the respect ve edges 17 of the slidable bar 14:, the guide 15 being provided with openings 18 for the reception of the means whereby it is secured to its support. i

The slidable bar 1 1 is provided adjacent its outer end with a longitudinal slot 19. A screw nut 20 is secured in the material of the door or window transversely thereof in any desired manner. A screw-threaded spindle 21 engages the threads of the nut 20, and is provided upon one end with a square shank 22, to which is secured an operating handle 23. The opposite end of the spindle 21 extends through the door or window and is provided with an operating handle 24, secured thereto in any suitable manner. This spindle'eXten-ds through an opening 15 formed in the guide 15 and through-the slot 19, of the slidable bar 14.

The collar or base 25 of the inside handle 23, will, when the door is fastened, bear upon the bar 1 1-, and the collar or base 26 of the outside handle 2 1 will be slightly spaced from the door. The length of the spindle between the handles is such that when the collar or base of one handle is bearing against the surface opposed thereto, there is, on the opposite side of the door, a small gap between the collar Or base of the other handle and the surface opposed there to. If desired, a plate 27 may be secured to the door intermediate the outer handle 2 1 to the door or a flange may be formed upon the nut 20 against which the collar or base 26 of the handle may bear. When the spindle is partially rotated by one of its handles, it will move longitudinally in one of the screw nuts according to its direction of partial rotation.

In the form shown in Figs. 6, 7, and 8, the door or window opens outwardly. In connection with this construction, I prefer to employ a curved bar 10 which will allow a further opening of the window than is possible with a straight bar. Furthermore, in this construction, thehandle 23 will, when the window or door is in the closed position, be arranged in the end of the slot nearest the pivotal connection of the bar 10 and the slidable bar 14, whereas in the forms shown in Figs. 1 to 4, the reverse of the above arrangement is true.

.Where'the window opens in only one direction, it is unnecessary to providea handle upon thev outside thereof, and this handle 1 may be substituted, as shown in Fig. 7, by i an enlargement 29 formed upon or secured to the spindle 21. If desired, the spindle may be of such length that it only extends partially through the nut 20' in this form of my device.

The'operation of my device is as follows: 1 When the door is fastened in its closed position, the collar or base of the inside handle 23, presses against the slidable bar 14. and prevents the door 13 from being moved. hen the handle 23 is turned, the spindle 21 moves longitudinally of its own axis in the nut 20, and the pressure on the slidable bar is released. The collar or base 26 of the outside handle2 l then bears against the door 13 or the intervening plate 27 and the slidable bar 14 can move backward and forward with respect to its guide 15 and allow the door to be opened and closed to the desired extent until it is secured in its adjusted position by reverse rotation of one of the handles. It will be understood that if the outside handle be fixed to the spindle so that when turned it will. rotate the spindle,- the same effect can be obtained by rotatingeither of the handles. 7 f 1 It will beobvious to those familiar with the artthat' my adjuster may be readily combined with the ordinary rim loekby simply utilizing a slightly longer square. shank 22 which will extend-through the square open ing generally I formed for the reception of the knob shaft in this type of lock, as shown in Fig..'10. It will furthermore be obvious that but very slight changes are necessary inthe construction herein shown to enable its combination with the usual mortise lock, this being effected by screw-threading the ends of the spindle 21 and forming the central portion thereof with a square shank which will enter the squared opening pro-Q vided in the lock for the knob shaft, as

shown in Fig. 9. The threaded ends of the spindle 21 will be mounted in 111117320 ar- 7 rangedupon opposite sides of the mortise lock. Y 7

. It is to be understood that the form of my invention herewith shown and described are to be taken as a preferred exampleof the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the'inve'ntion' or the scope of the subjoined claims. 1
