CORPORATION OF MASSACHUSETTS WINDOW-PULLEY SHIELD Application filed June 22,

My present invention relates to shields, particularly adapted for use in conjunction with window cord pulleys.

It is a well known fact among architects, builders and house owners that serious drafts are caused by the entrance of cold air through the space formed by the window casing and through the spaces provided for the sash cord pulleys. An important object of the present invention, therefore, is the provision of a novel shield to be applied to the window frame to overcome these drafts and the in convenience and dangers caused thereby.

Another object of the invention resides in the provision of a shieldof this nature which is simple to manufacture and apply.

A further feature of the invention resides in the fact that my novel shield may be affixed to the 'escutcheon of the pulley without disconnecting the sash cord. I utilizethe ori inal escutcheon screws for securing the shield in place.

A further object of the invention is to provide a shield which in and of itself, without the use of cushioning material or lining layers, will be substantially weather-tight, there being no opening therethrough except that through which the sash cord passes, and which opening is formed to permit a snug fit of said cord. In actual practice I have established the fact that with the use of my novel shield there is not the slightest perceptible draft through this vulnerable part of building construction.

Further features of the invention reside in the particular details of construction of my novel shield.

The above and other objects of the invention, details of construction, and advantages, Will be hereinafter more fully pointed out, described and claimed.

Referring to the drawings, illustrating a preferred embodiment of my invention,

Fig. 1 is a vertical'sectional view illustrating my novel shield in position;

Fig. 2'is a cross-sectional view on the line 22 of Fig. 1;

Fig. 3 is a front elevation of my novel shield; and

Fig. 4: is aside elevation of said shield.

1929. Serial No. 372,957.

Referring now to the drawings, for a particular description of the invention, its construction and assembly, 1 designates a plate, on which is struck up or formed a housing 2, the lower end of this housing being narrowed and forming an opening 3, the edge of the housing adjacent to this opening being flared or belied, as at 4, to prevent chafing of the sash cord 5 ontrave-ling therethrough.

One end of the sash cord 5 is affixed to the Window sash 6 and the other end of said cord is afiixed to a weight 7, this weight being vertically movable in the well 8 of the window casing 9. The cord passes over a rotatable wheel or pulley 10 mounted on a shaft 11 fixed in the Walls 12 of a frame 13. An escutcheon lat isusualy affixed to the frame13 and the escutcheon and frame are afiixed to the casing 9 by screws 15. This escutcheon is countersunk at the screw holes, as clearly illustrated in the drawings.

My novel shield is provided with a pair of apertures alined with the screw holes in the escutoheon, and the back side of said shield,

adjacent to said apertures, is provided with 7 annular lips 16 adapted to seat in the countersunk apertures in the escutcheon to aline said shield and prevent longitudinal or lat eral movement thereof. In attaching my shield, the screws 15 are removed, the shield applied to the escutcheon 1 1- with the lips 16 positioned in the countersunk apertures therein, and then the screws 15 are replaced.

In order to permit the application of my novel shieldwithout disconnecting the sash cold, I provide the same with a lateral line of out or split 17, the .contacting faces 18 and 19 of this line of out being beveled, as clearly illustrated in Fig. 4. The shield is constructed of metal with sufiicient resiliency to permit the lower end thereof to be sprung or pressed open, along this line of cut 17, whereupon-the shield is slid over the cord 5 until the cord is seated in the opening 3, whereuponthe contacting faces 18 and 19 are pressed together,-and the screws 15 applied. The beveled face 19 being above'the face 18, when the lower screw 15 is in position, the pressure of said screw will force the faces 18 dow may be raised or lowered as before, the

and 19 together, insuring that the shield will lie fiat and snug against the escutcheon 14.

lVith my novel shield in position, the winhousing 2 being sufiiciently narrow and shallow to slide in the groove 20 formed n said window to normally receive the projecting portion of the pulley 10 and the cord 5.

It will thus be apparent to those skilled in the art that my novel shield will function to prevent any draft from entering through the openings formed for the cord pulleys 10, and that said shield is simple to manufacture, economical and easy to apply, it requiring-"hut a minimuinof time to remove the screws 15, slide the shield over the cord and aline it with the escutcheon lat and then replace the screws 15. i i v I believe that this shield is novel, and have therefore claimed thesame in the present up plication.

lVhilc I have necessarily described my presenti vention somewhat in detail, it will.

be appreciated that I may vary the size, shape and arran 'en'ient of parts within reasonably wide limits without departing from the spirit of the invention. 1

It will be appreciated that my shield may be adapted for use with window chains, or the fiexiblemctal stripssoinetinies utilized, without material alteration or change, and that such use is well within the range of my present invention.

It will also be a preciated and understood that by the use 0. my novel shields, the entrance of dust or dirt at these vital points is eliminated, thus obviating a source o'f great discomfort inconvience to householders,

and resulting in a much cleaner interior of the house after the installation of my novel" shields. This also means less expense oi upkeep and maintenance, as well as maintaining a neater, cleaner and more orderly condition in the house, apartment or building in which my novel shields are utilized.

My invention is further described and (lefined in the form of claims as follows:

1. A shield for window cord pulleys, comprising a plate, a housing formed thereon, the lower end of said housing having an opening therein, and the edge of said opening being flared to prevent injury to a cord traveling therethrou gh, the said plate having a slit communicating with said'opening, said plate having suilicient resiliency to permit sprea dingat said slit, whereby the shield may be applied over the window cord while said cord is in position.

2. A shield for window cord pulleys, com

cient resiliency to permit spreading, whereby the shield may applied over the window cord while said cord is in position, the said plate, at said lateral split, having beveled contacting faces so constructed that when said plate is attached the said plate willli'e flat. 7. 7 7 V 3. A shield for window cord pulleys, comprising a plate, a housing formed thereon, the bottom end of said housing having an opening therein, the edges of said opening being flared to prevent injury to a cord traveling ther-ethrough, the said plate having fit connnunicating with said openi j kl having suflicient resiliency to permit ing at said slit, whereby the sh ld in-i applied over the window cord wl id u is in position, and the edges of nu slit be a normally in substantial engagement.

In testimony whereof, I have signeril my name to this specification.
