To aZZ whom it may concern.-

Be it known that I, GEORGE DWIGHT CLARK, a citizen of the United States, residing at Plainville, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Sash-Cord Guides, of

M3" invention relates to improvements in provements are simplicityand'economy in efficient is aside elevation of m y' sash cord guide. Fig.

the black from which I make said frame. Fig.

The pulley A and its axle pin 5 may be, of any ordinary construction. The axle pin is from a sheet metal blank cut out in substan tiallythe form shown in Fig. 4 and bent up into the form shown in Figs. 1, 2 and 3. The middle portion of this blank is slotted longiin the blank opposite the ends of said opening is trimmed to the proper form and width as at. 7 7 to form the ends of the face plate 8 On each side of the middle portion of said blank I form a Wing 8 for forming the sides or checks 9 of the frame- The ends of these wings project beyond their junction with the middle portion of the blank thereby forming the slots 10 and free ends 11 for forming the top and bottom sides 13 of the frame in connection with the vertical sides. Suitable perforations 12 are made to receive the axle pin 5. The blank thus formed is bent by doubling the metal upon itself along the broken lines of Fig.4 which define the longiwith a reverse bend on the dotted lines in said Fig. 4. to bring the cheeks or vertical sides 9 The free cheeks and the face plate maybe extended farther up ordown withreference to the opening in the face plate. shown such a modification which consists substantially in merelyomitting the free ends 11 from the blank and consequently omitting the top and bottom sides 13 from the frame, the general construction remaining the same as first described.

By' my invention I form the face plate and sides of the frame of sheet metal in a simple and inexpensive manner. It should also be noted that the vertical sides or checks 9 9, are set infrom the folded longitudinal edges of the face plate so that the projecting face plate may cover. the entire month of the mortise, the same as it does in a frame'in which the In Figs.5 and BI have projecting edge of the face plate consists of a single thickness of sheet metal. By this construction, the face plate by the sides of the pulley opening, where it is generally the weakest, is very much strengthened.

I claim as my invention- 1. The herein described frame for a sash cord guide consisting of the face plate 8 and sides or checks '9 formed of sheet metal, with the metal at the longitudinal edges of the face plate doubled upon itself and projecting laterally beyond the side surface of said cheeks substantially as described and for the purpose specified.

2. The herein described frame for a sash cord guide consisting of the face plate 8, sides or checks 9, and top and bottom sides 13, formed of sheet metal with the metal at the longitudinal edges of the face plate doubled upon-itself while the top and bottom sides are turned inwardly from free ends of the cheeks above and below said doubled edgcs,substantially as described and for the purpose specified.
