, i I sAsH-com) HOLDER.

To all cchom it may concern:

a citizen of the United States, and resident of Milwaukee, Milwaukee county, VVisconsin, have invented new. and useful Improvements in Sash-Cord Holders, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification. l

i This invention has for its object to provide a window sash cord holder which may be conveniently clamped 011 the sash cord to temporarily relieve the sashof the influence f of the sash weight or spring at suchltimes as when the sash is disconnected from the sash cord for cleaning or repair.

The present application constitutes acoutinuation in part of application Serial No. 52,825, filed September 27, 1915, for demountable windows.

With the above and other objects in view,

the invention consists in the sash cord holder as herein claimed and all equivalents.

Referring to theaccompanying drawings, in which like characters of reference indie cate the same parts in the different views: 7

,Figure l is a View of a window showing the sash cord holder of this invention in use while the window sash is swung on pivotal connections to remove it from the window frame for cleaning; 1 t Fig. 2 is a detail view of the sash cord holder on a larger. scale; Fig. 3 is a sectional view manner of engagement of the the sash cord; and,

showing the Fig. 4 is an edge VIGW of a window sash equipped for readily disconnecting thesash cord and attaching the sash cord holder in the manner shown in Fig. 1. e e

end of the cord out of reach and'will some-- times cause the cord to break, or the knot on the end thereof to slip through the pulley housing so that it is difiicult to make repairs.

The sash cord holder of this invention is provided for this purpose.

A rod, forming a handle 16 of suitable length, has secured to one end a metal blade 17 which is preferably V-shaped in cross-sec;-

tion with its trough or channel parallel with the handle. The blade extends to one side of the handle and its front end is provided with a Vshaped notch 18 to facilitate its (511- gagement with the sash cord and to permit the blade to fit closely between the sash cord and the pulley 13. The bottom of the trough is made wedge-shaped for a short dis* tance with the point of the wedge at the crotch of the notch 18 and when the blade is formed of sheet metal as here shown that portion which is cut to form the. V-shaped notch isrnot entirely severed but the two lines of cutterminate a short distance from each other and the tongue of metal between them is bentinto the trough to produce the wedge referred to and is held in place preferably by means of a rivet 19 passing through it and the bottom of the trough. The lower end of the wedge forms an abrupt shoulder 20 in the channel of the trough over which the sash cord passes. A crank pin 21 is journaled in a groove in the handle 16 being held within the grooveby the blade 17. One end is bent to form a V-shaped crank fitting the channel of the trough 17 i and bearing against the shoulder 20, while the other end is bent to form a crank arm which is connected by a connecting rod 22 with an angular lever 23 pivotally mounted on theother end of the handle. At an intermediate pointthe connecting rodr22 is bent to form aneye for engagement with 22 and turn the crank pin 21, so as to hold its end against the shoulder $201 To engage the sash cord holder the lever handle inember having a crank portion to clamp the sash cord between 1t and the shoulder of the hook member, a sprmg-actuated connecting rod connected with the crank pin, and a' lever on the handle connected with the connecting rod.

23 is pressed against the handle, therebyflwmi A sash cord holder, comprising a b pushing the connecting rod 22 against the action of the spring Ql to swing the crank pin 21 away from the shoulder 20. The hook formed by the blade is then passed behind the sash cord and is pushed upg wardly until it bears against the pulley 13 when the lever 23 is released permitting the spring 24 to move the crank pin into en'- gagement with the sash cord and sharply bend it around the shoulder 20,- as shown in Fig. 3; This clamping engagement of the holder with the cord, together with the hearing of the holder against the sash pulley,

prevents the return of the sash cord under the influence of the sash we1ght and leaves theknotted end of the sash cord where it may conveniently reengage with the sash when it is desired to return the sash to the Window frame.

In using the device with window sasl pivotally swung from the window frame, as

shown in Fig. 1, it is not onlydesirable that both sash cords should be. secured in this mannen by the sash cord holder, but it is desirable that the sash cord holder at the side of the Window sash which is pivotally mounted should be utilized as a means for suspending the other side of the window sash. For this purpose a coil spring is connected at one end to an eye 26 on the end of the handle 16 and at the other end to an eye 27 secured to the sash. This serves to cident to the pivotal connection with'eut support the sash at both sides thereof and avoid a racking tendency that would be insuch additional support, particularly with avery w1de sash or a weakenedsash;

1 To facilitate the removal and attachment of the knotted end of the sash cord, the opening in the end of the groove at the side of the sash may lee-provided with a pair of inclined parallel pins 28 between which th knot may be readily slipped.

The sash cord holder ofthis invention is quickly appliedor detached and makesa 1. A sash cord clamp, comprising a loan =dle-member, a hook member thereon of a U- shape in cross section and having a V-shaped notch to fit over the sash cord; a shoulder on theiho'ok member, a crank pin on the notch :at its end, said notch being adapted dle member, a metal blade secured thereto and having a groove formed therein with a to be engaged with the sash cord near its pulley, and a clamping member oh the hendl'e' having means for moving with spring pressure' tevvard the blade to clamp the sash cord therebettveen.
