ATTORNEY WITNESSES GEORG-jl. gunman, or sar seahorses, chairman-nu inseam-se ters a t a To all whom it may concern:

Be it known that I, Goose T. EKLUND, a subject of the King of Sweden, residing at San Francisco, in the county of San Fran cisco and State of California, have invented new and useful Improvements in Swingin Sash Connect-ions, of which the following is a specification. I

- The present invention relates to improve ments in that class of windows, which swing on a horizontal axis, for the pur ose of obtaining access to both sides or" t e Window for conveniently cleaning it.

The object of the invention is to provide means for securing the sash to the frame, such that it can be so swung on a horizontal axis without any danger of the sash droping on account of slight imperfection of the mechanism, or of the sash being disengaged from the frame.

In the accompanying drawin Figure 1 is a vertical section of a window rame showing in side view a sash, equipped with my invention; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a section on the line 33 of Fig. 1; Fig. 4 is a section on the line 4*; of Fig. 1 on an enlarged scale.

Referrin to the drawing, 1 indicates the 1 top, 2 the bottom and 3 a side piece of a window frame, and4 a sash therefor. Said sash and frame are here shown as constructed of sheet metal,although itwill be obvious from the following description thereof, that they can, with slight changes in the construction, be made of wood. In the inner side of said side piece 3 is formed a groove 6, which may have an angular pocket 7, known as a dust pocket, for the purpose of receiving any dust which may enter it. Secured near the top of said frame on the outer side of its face, by a pivot bolt 8, is the upper end of a hanger 9, which depends in a vertical plane at right angles to the plane ofthe window, and the lower portion of which is pivotally secured to the outer projecting end 10 of a bracket 11, the greater part f which is depressed and secured to the sash 4 in a'groove 12 in its side. The other erid of said bracket extends outwardly fromisaid sash, and is piv otally connected, as shown at 14:, to one end of a link 16, the other end of which is pivotally connected to a shoe 17, the sides of which are, as shown at 18, bent around the edges of a vertical guide plate 1.9 secured by bolts 21 in the groove 6. To said lint; 16 t pivoted, at a point 22 about midway of length, one end of an auxiliary link S33, other end of which is ivotally connected to a shoe 24, the edges 0 which move in'slide ways 26 secured upon the edge ot the sar 6L- the edges of the shoe being bent u. to pro duce a spring pressure against said guide' ways.

The top of the window sash is, at each side, slidably secured to the guide-plate 19 by a shoe 2? similar to the shoe 1?. Hence if lower portion of the sash be pressed outward, its upper ortion will descend vertically, being guided by the guide-plate in the window frame.

In order to insure the sash remaining in the position to which it has been opened, ii secure, by screws 29 in each ed a oi the at the top, a guide plate 31, in t e upper per tion of which is a bearing 32 for a pin 33, To the outer end of which is pivoted, shown at 34, to the middle portion of the shoe 1%", precisely similar to the shoe 17, and which has hook-shaped edges engagine the edges er the vertical guide-plate 19. said pin is normally pressed outward by means oi? a bent spring 37, of which the ends are bent in the proper direction to enter a socket. in the inner end of the pin, and the central portion is secured to saidplate by a screw 38 and washer 39. The pressure of this spring is imparted by the pin 33 to the shoe 2? and causes said shoe to be pressed against the guide-plate 19 to exert friction thereagainst, which is sui'hcient to overcome the force or gravity tending to move the window sash out of the position to which it has been opened.

In combination with a window frames a sash, a hanger bar pivotally connected its upper end to the window frame, and at its lower end to the side of the sash, a link one end of which is pivotally connected to a side of the sash, a shoe pivotally connected to the other end of said link and haw/in frictional slidable engagement with a side of the window frame, the upper ortion of the sash having also a frictional on gla zgement with said mile of the window In testimony whereof I have hereunto set ame, and an auxiliary link, one end of my hand in the presence/of two subscribing 10 which is f ngot-sally eonnegt igfllzo admedilzltte witnesses.

ortioh o t e. rst-name ,an a s 0e V 5 $0 which the other end of the last-named GEORG EKLUND' link is pivotally connected, said shoe having Witnesses: a frictlonal slidable engagement with said FRANCIS M. WRIGHT, side of the sash. D. B; RICHARDS.
