Sesia-OPERATING DEVICE.

Specification of Letters Patent.

Patented Mar. 11, 1913.

Application led September 20, 1909. Serial No. 518,488.

vTo all wiz-0m t may concern .Be it known that I, ANDREWS ALLEN, a citizen of'the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Sash-Operating De of which the following is a specification.

This invention relates to means for operating and locking easement windows, screens, shutters, and the like, and has for its object to provide a device which will enable a easement window, or other sash or shutter hinged at one edge, to be opened by a direct outward thrust; to provide an operating mechanism which will beread-ily adapted to easement windows of the like where screens,y when employed, are necessarily placed on the inside of the hinged sash; and to provide an operating device which will automaticallyv lock the window and also the screen when in the closed podv sition. To accomplish these and other desirable advantages which will appear in connection with the particular description of the invention, I construct the operating mechanism in the form of a jointed bar, the joints being of unequal length, the shorter one having a pivotal connectionwith a'n attaching member or bracket for securement to the sash, and the longer one having its inner end preferably fashioned. to provide a finger hold and guard. Both members of the operating bar are preferably provided with perforations for the passage of alockin pin. A guide member or keeper is a apted to be secured to the window sill and is provided with a guide slot through which the operating bar reciprocates, and with a vertical perforation for the locking pm.,

In the accompanying drawings-Figure 1 is a sectional elevation through the lower portion of a easement window, a screen, and the window sill and water table, showing the operating device in sideV elevation and in closed and locked position, and also by dotted lines in open position; F ig, 2 is a perspective view of the device detached from the window; Fig. 3 is a sectional detail plan View of the guide keeper and operating bar, the latteivbeing broken away, the dotted lines showing different positions of 'the bar Fig. 4 is a transverse sectional view through the Window sash, screen, one side frame, the sill, water table, the operating devlce show- Iing in plan view; Fig. 5 is a detailed view showing a modification in the construction of the hinge joint of the lookin bar; and Fig. 6 is a fragmentary view o the upper end ofthe screen showing a hinge therefor.

In the drawings, 7 indicates the lower frame bar of a easement window.

Sindicates the window sill and 9 the water table. y v,

10 represents the frame of a ily-screen and 1l one of the hinges whereby the screen is suspendedfrom its upper end.

It will be understood that the window may be hinged at one edge as shown at 12 (Fig. 4);

Usually in easement windows the sill is very narrow and the space allowed for the mounting of the window sash and the screen is restricted; therefore, it is important to provide an operating means for the window sash which is adapted to these narrow limits;

My improved operating device is shown complete in Fig. 2, wherein 14 and 15 represent two plates constituting a guidekeeper, and whichas shown areformed separately for convenience of construction, but which might be made integral. The member 14 has an upstanding flange 14a and a hori- ,zontal shelf-like portion 14h.' The flange 14 isparted at its middle to permit the passage of the operating bar, the parted portions 14 being arranged at an angle and converging" rearwardly to constitute ,guides for the op erating=barg on the extremities of the por tion 14 the operating bar fulcrums Whenfthe window is opened wide. The keeper may be attached at either side of the window. The shelf-like port-ion 14h and the base member 15 have registering perforations for a locking pin 16 and other perforations 14d for fastening screws'. The operating bar is composed of two members 17, 18 hinged together by a pin 19, the member 18 having a knuckle 18, as shown in Fig. 2. This knuckle may, as shown in Fig. l5, be extended, the slot in the member 17 being correspondingly lengthened, so that the extension will abut against the edge of the shelf 14", thereby affording a lock for the screen and vWindow when closed and t-he member 18 falls into vertical position as indicated in Figs. 1 and 2. The outer' end of the member 17 is pivotally connected to the bracket plate 20, which will be secured 'by means of screws to the bottom bar 7 of t-he Window the extent of piece 18b example, by

sash. The keeper projects beneath the screen, the lower bar 10 of which mayfbe out away to permitits passage.

With the parts constructed and arranged as above described, the window sash may be opened and' locked in any desired posi-y tion of adjustmentby a straight thrust of the operating bar, and the latter during the early part of itsJ movement being extended in a straight line. When movedto the full extent the bar will assume angular positions such as indicated by the dotted lines in Fig.y

3, the degree of angularity depending upon the movement; but the bar is' operated by a 4straight thrust and is guided by the members 14Cc at all times regardless of the extent of the mor/ement. -Thebar is locked in theattain'e'd position by the insertion of the pin 16 through the aperture of the base plate inside of the screen, ing pin passing through one of .the apertures of the bar 18.' This bar is preferably provided at its free" extremity with a finger and a guard 18c affording convenient means both for moving the bar and protecting the fingers against injury. Theseparts may be formed in other ways, as, for

circular form.A Whenthe member 18 is in the pendent position indicated inrFi'gs. 1 and 2, the device' would be locked since it would be difficult to apply sufficient orce from the outside to `raise this depending member anddraw'it through the keeper. `IA

Y Jointing the operating rod has several ad vantages, as follows: The device' may `be adapted to windows of anyI w dierent widths of sills; the rod when Very long would be objectionable because it would be in the way if made in a single piece; and by jointing the rod the inner member affords an efficient lock.-

for example, in the pin in the ioekbending the. end 'of the bar to width and.k to

remesa Obviously, structural variations may be made within the scope of lmy invention, as, proportional length of the two' members of the operating. bar; in the specific character of the locking pin and perforations; and in the form of the guide. The guide may be countersunk. in.the window sill or covered4 by af false sill-.to avoid .cutting the screen sash.

I claim: 4

1. In a window sash Voperating device, the combination of a jointed operating rod having a plurality oi locking apertures therein, a guide member having an to register with anyl of saidrodapertures, a two of said registering apertures whereby said` rod and vguide member are locked together, and a pair of guides proper constituting part of said guide member having free edges., contacting opposite sides of said rod in a vertical, plane substantially through said pin, whereby said pin alone holds said rod inlockedposition and wherebya close sliding connection is maintained between said guides proper and said rod in varying angles of the rod, substantiallyvas described.

2. In 'a window sashoperating device of the class described,- .the combination ,of an operating rod, a guide member, said guide member having an end portion comprising a -base and a 4cover and'an upstanding wall between said base and cover, said wall being divided l centrally and the divided parts thereof'bent apart to form guides prop r, said rod being in sliding'contact with t e edges of saidj guides proper, said base and Vaperture adapted cover portions having registering apertures substantially `in the Vertical plane oi'El the ends of said guides proper, said rode-having 96 engagement with saidrod to take up wear,

and whereby said guides Iproper are :Ere'e frombinding action of isaidrod, substantiallyas' described'. ANDREWS ALLEN. Witnesses:
