To all whom it concern:

Be it known that I, HENRY J. DAVISON, post-captain in His Majestys royal navy, a subject of the King of Great Britain, residing at Moorfield, Sutherland avenue, Bexhill, in the county of Sussex, England, have invented new and useful Improvements Relating to Windows, of which the following is a specification.

This invention relates to windows of the gether and inserted in a single frame. Obviously in such windows the hinge line may be either vertical or horizontal, the pins which guide the sash beingplaced either in slots at the top and bottom or in slots on the two sides respectively.

The invention consists in an improved method of locking such a window in any desired osition,'and is, of course, equally applicable to windows of both types. As, however, the window having a vertical hinge possesses many advanta es over the other form, the invention will e described as applied to this type.

The invention is illustrated in the accom- Figure 1 shows an elevation of the window in its closed position, as seen from the outside; Fig. 2 is a sectional plan of the same, indicating also in, dotted lines the enlarged detail view showing parts of the end of one of the windows in section to illustrate the locking mechanism; Fi 43 shows'the same parts in section in a p ane 5 is adetail view showing the locking lever of the window.

As will be readily seen from Fig. 1, the window consists of two main sash frames a, a, which are united by hinges in a vertical line at b. When in the open position,

tical line I) lies some distance from the plane of-the sashes, while the two remote ends of the two frames approach closer'together. Each of the frames carries at the top and bottom on its outer end corner plates a secured to the frames by screws or the like, ,and bearing cylindrical bosses which are produced to form pins (1. These pins are inserted in corresponding holes in small plates of'metal e, which d1 er in the Specification of Reissued Letters Patent. Reissued Oct. 25, 1910.

top and bottom of the window. Those at the top of the window are simply short bars adapted to slide within the smooth channel bar f. Those at the bottom have formed on their under surface racks g which do not, however, extend throughout the whole breadth of the slip. The smooth edges of the slip rest upon two angle bars h at the bottom of the window. These bars are joined at intervals at the bottom by rivets is surrounded by sleeves or rollers m.

In order to lock the window, a rack bar at is arranged beneath it, and this when raised is adapted to mesh with the two racks g and soretain them in any position in which they may be found. The bar a may be raised in various ways. In the device iilustrated, it has beneath it a second smooth bar 0, which rests between the lowest vertical portions of the angle bars. h.

The bar 1' is further connected to the bar 0 by the slotted projections 3} upon it, engaging over pins i on the bar 0 so that the rack bar is moved down, as well as up, positively. On the underside of this bar are a number of notches p, arranged at the positions of the rivets 7c, and these notches have one side sloped so as to form an inclined plane which can ride up the "rollers m. At the center of the bar 0, or in any other suitable position, there is provided a projecting framing of the window through a slanting slot in the angle-bar h, and lies between the vertical ends of a forked lever r pivoted at s. This lever carries a hollow boss 25 in which is mounted a pin a, pressed downward by a spring to. In one position of the lever a" thepin u is forced into a hole at in the plate on which the lever is mounted and so locks the lever in position. A bent strip 31 secured loosely on the pin 2: serves to raise the locking pm. I

The action of the paratus will be understood at once. len the lever 1 is moved, say to the right, the stud g is pushed to the left, and carries with it the whole bar 0'. The sloping surfaces of the notches p riding up the rollers m raise the bar 0, and

with it the rack bar-n, the stud g moving metal 0, vso locking the window, while the 1 'lever'r in the locking posit-ion.

nations or omissions as these do not affect the hole at and retains the The fact that the rack bar n is so arate from the bar 0 permits the former to rave a slight lateral movement, so that in case its teeth should be lying directly beneath those of the racks 9, it can be shifted sufficiently to bring the teeth into mesh. To assist in this action also, the teeth may be formed with suitably rounded tops. As mentioned above, the angle bars h are not united at the bottom save pin u drops into by the rivets k, and preferably the slot in the wood framing in which they are placed is a little deeper than the angle bars, and has its lowest surface sloped to one side, with a channel 1 leading from the slot to the under side of the sill or other convenient position. In this way, any water which may enter the slot is drained off without inconvenience.

Obviously many details of the device are open to variation. For example, various means may be provided for making a tight joint in front of the hinges at In the form shown in Fig. 2, there is simply a pro jecting bead 2 on the one frame a, which in the closed position overlaps the ed e of the other frame, while a tongue 3 is a apted to enter the rabbet- Devices such as'thiswill be obvious to those acquainted with the art,

and as they form no part. of the invention, i need not be further described or illustrated.

In a similar way alterations may be made in the manner of raising the rack. bar n. For example, an obvious alternative is to provide pins on the bar 0 and sloping slots in the channel bars 71. These will effect exactly the same purpose and effect it in the same manner. Another alternative is to use eccentrics beneath the bar orotated by projecting shafts, but in this case it is difiicult to get the required leverage, and to operate the window from one handle. Many such devices as these are known to be mechanical equivalents, and it is not necessary, therefore, to outline them all in this place. It is possible also to actually do without the teeth upon the bar a and the metal slips 6. These teeth, it will have been seen, provide a positive means for preventing relative movement between the window and its guides, but it will generally be suflicient to secure the window by frictional engagement between two surfaces, and in this case smooth or slightly roughened bars will be all that is required in place of the rack bar 12 and the slips 6. If desired, also, the bar it may be normally pressed up by springs, and may be forced down to release the window in some one of the ways suggested above for raising it. Obviously also it may in some cases be possible to do without the forked lever r, since this only serves to reduce the force required to move the stud 9. Such the working of the invention, and are, t herefore, to be considered within the scope of the application.

Having thus described my inventlon, what I claim as new and desire to secure by Letters Patent, is
