Specification of Letters Patent.

Patented Feb. is, rear.

To all whom it may concern:

Be it known that I, ELIZABETH M. MsNzL, a citizen of the United States, and a resident of Steinway, Long Island City, berof Queens, in the county of Queens ough an State of New -Iork, have invented a prevent the blowing of the curtain through the window and the soiling thereof, to hold the curtain away from the window sashes in order to permit unobstructed cleansing of the window, and other purposes.

Another object of the invention is to provide ana'djuster fixed normally to the window frame so as to swing either inward or outward and be held automatically in substantially a horizontal plane forholding a curtain, or its equivalent, spaced from the plane of the window on either side.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in whlch like reference characters designate the same parts in the several; =views, and in which- I Figure 1 is a perspective view indicating the manner of use bf my improvement.

Fig. 2 is a fragmentary view of that portion of my improvement attached to the right side of the window and projected inward, the cross bar-being in section.

Fig. 3 is a view similar to Fig; 2 but showing the arm in normal idle uprlght position parallel to the-window frame.

F 5 is a similar vlew of oneend of the Fig. 6 is a vertical sectional detail on the line 66 of Fig. 2. I

Fig. 7 is a transverse sectional detail on the line 77 of Fig. 2.

Fig. 8, is a somewhat similar view but showing the manner of manipulating the inner and outer arm sections to effect the adjustment thereof.

Fig. 9 is a fragmentary view indicating a preferred form of crossbar.

Referring now more specifically to the drawings I show my improvement as com- PIISlIlg two telescopic arms 10, a crossbar 11 and pivot connections 12 to secure the end of each of the arms to the side or vertical members 13 of the window frame.

Each of the arms comprises inner and outer telescopic members 14 and 15, the inner member being preferably in the nature of a fiat solid bar of any suitable material and having at what I may term the lower end a pivot hole 16 for a pivot pin 17, and having on opposite sides of the hole 16 shoulders 18 and 19 for cooperation with a. fixed stop 20. The pivot pin 17 and stop 20 may be of the same nature, such as screws or nails, and both serve to hold the pivot member 12 as a whole against the Window frame 13. The pivot member comprises two disks 21 and 22 having registering holes for the respective pins 17 and 20. The disks 21 and 22 are thus securely fixed to the window frame and may have any suitable degree of closeness or tightness toward each other for the purpose of gripping the lower end of the arm section 14, this being deter mined by the distance to which the pins are driven into the frame. The shoulders 18 and 19' are shown as lying at one side of or above the transverse diameter of the joint end of the arm 14, and hence by locatmg the stop 20 substantially in the vertical length terminating in a squareupper end.

At any desired points intermediate of its ends it is provided with headed studs 23 in the nature of a round headed screw fitted rigidly in said arm section, .but with the head spaced from the am The outer arm section 15 is tubular and is provided on one side with a channel 15 whlch is substantially coextensive with the section 15 and along and within which the head of the stud 23 is adapted to glide during the extension orcontraction of the arm. Near the open lower end of the member 15 its channeled portion 15 is provided with a keyhole slot 21, the larger end of which is directed toward the open end of the arm and is adapted to permit the free passage therethrough of the head of either stud 23 while the smaller end of the slot 24 is adapted to embrace the shank portion of either stud to determine the degree of adjustment of the arm. As shown in Figs. 2 and 3 the length of the arm 10 is intermediate of its two extremes, the solid portion of the member 15 being in cooperation with the lower A stud 23. If it is desired to shorten the arm the operator has simply to release the stud 23 from the smaller end of the slot and by pressing laterally on the fiat side of the member 15the slotted portion of the member will be passed over the head of the stud so as to permit free endwise movement of the member 15 toward the pivot 17. Likewise if it is desired to adjust the arm at a longer length the member 15 will be moved outward to bring the outer stud into registry with the key-hole slot where it may be locked in a manner similar to the illustration of the locking in connection with the lower stud. The outer member 15 of the arm is made somewhat larger in transverse dimension than the solid member 14 so as to provide for the adjustments above referred to.

The outer or upper end of each arm section 15 is preferably substantially solid and flat and provided with a bearing 25 of substantially cylindrical form but having an open side 26 narrower than the diameter of the bearing. The crossbar 11 is provided at each end with a head 27 and a relatively narrow neck 28. This neck is fiat in one dimotion and cylindrical in the other direction, the fiat dimension corresponding to the opening 26 of the bearing sothat when the bar is turned in the proper direction the neck portions thereof will slip freely through the side openings 26 and then by turning the crossbar sllghtly around its axis the neck willinterlock in the bearings 25 so as not to drag therefrom even though the arms be swung outward through the.

window.

The manner of use-of this device may be briefly set forth as follows: In view, of the foregoingspecific description of the mechanism as shown in Fig. 1 the crossbar 11 is supported upon the bearing ends 25 of the arms and in a substantially horizontal position. Obviously the pivot connections 12 may be located as h' 1 window frame as ind lvidual desires or conh or as low along the ditions may dictate so as to hold the curtain spaced from any desired portion of the window. When the curtain is not desired to be held in this manner from the window the device is disconnected by rotating the rod 11 to disconnect it from the bearings 25 and then the arms are swung upward around their pivots and the,open sides of the bearing holes 25 are passed over nails or screws 29 fixed at any desired elevation to the window frames above the pivots 17 These nails or screws 29 serve therefore as keepers for the arms in idle position. The rod may be laid on the window sill or on the floor, or otherwise adj acentto the window for subsequent use. Whether the arms be contracted to their shortest length prior to adjustment into idle position Wlll depend upon the location of the keepers 29 or the operators individual preference. The crossbar 11 may be solid if the length thereof is capable of being determined suitably, but in order to adapt the device to windows or the like of dilferent widths I prefer to make the crossbar ofa telescopic-nature composed of two parts 11* and 11*, but having same end characteristics that are fully set forth above in connection with the interlocking engagement with the outer arm members.

' I claim:

1. In a curtain adjuster, the combination of a pair of arms, means to permanently pivot the lower ends of the arms to a window frame and a crossbar supported upon the upper ends of the arms, each arm comprising inner and outer telescopic members, the inner member having one or 'more headed studs fixed thereto, the head of each being spaced from the inner memberand the outer member being provided with a general extension having a keyhole slot cooperating with either headed stud to determine the adjusted length thereof, substantially'as 'set forth.

2. In a curtain adjuster, a pair of arms ivotally secured at one end to avwindow rame, a-crossbar detachably mounted in the free ends of said arms, said arms having circular openings in their free ends and having narrow slots communicating with said openings, a flattened neck portion adjacent each end of the crossbar adapted to be passed edgewise through said slots and v turned to removably lock the bar and arms together, and means integral with the pivoted ends of the arms for supporting the arms in horizontal position.

3. A device of the character described in claim 2 including studs secured to the window frame and cotiperating with said slots, and openings to lock the arms in upright position against the window frame when thecrossbar is detached. v
