SASH-PULLEY.

SPECIFICATION forming part of Letters Patent No. 545,425, dated'August 27, 1895.

Application filed February 20, 1893. Serial No. 463,027. (No model.)

To @ZZ whom t 11mg/ concern: Ateach side of the body portion of the blank Be it known that I, EssINGTON N. GILFIL is formed an extension F, which lies midway LAN, a citizen of the United States, and a resiof the length of the body portion and extends dent of Chicago, in the county of Cook and outwardly at right angles therefrom and in 55 5 State of Illinois, have invented certain new the same plane as the body portion. Each of and useful Improvements in Housings for `these extensions is formed at its outer portion Sash-Pulleys, of which the following is a full, with a hole G, for a purpose to be presently clear, and exact description, reference being explained, and the blank itself is formed as a had tothe accompanying drawings, forming whole of thin malleable iron of nearly the 6o xo a part of this specification. thinness of sheet-iron, the metal being of My invention relates to the frames or houssufficient thickness and rigidity to withstand ings in which sash-cord pulleys are journaled, the strains to which it is subjected in use, and and which are designed to be mortised into at the Sametime of sufiicient liexibility to perthe jambs of window frames or casings. mit the blank to be bent into proper shape, as 65 y i5 Arnong the primary objects of my invention will now be described.

The advantages of thus bending the exin the housings and the consequent displacetensions F, so that their points H of union ment of the sash-cords from the pulleys.

Fig. 2 is a rear elemuch closer together than they would be if the 85 35 vation of a pulley-housing made from the bends were made, as heretot'cre,upon thelines Y blank shown in Fig. 1.

Hence shown in Fig. 4. there is no lateral play of the pulley between Referring to the drawings, D indicates an the brackets,such as willpermit the sash-oord elongated slot in the body portion ofthe blank to 'be thrown ott of the pulley, and all neces- 9 5 45 and extending longitudinally thereof, so as to sity, or, in fact, opportunity, for using hubs or leave at each end of the body portion an ear E. sleeves upon the spindles of the pulleys and Holes are formed through the ears E, one for extending the length of the spindles is th rough each ear, to receive screws or equivaavoided.

Such spurred ear may or may not be provided with a screw-hole, as preferred, and in either form of the housing the same is driven into the mortise and secured by screws or equivalent devices in the usual manner.
