Specification of Letters Patent.

. Application filed August 25, 1911. Serial No. 645.928. 1

Patented Mar.4,191 3.

To on whom it may concern Be it known that I, HENRY G. Guonon, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Window-Sashes,

of which the following'is a full, clear, and exact description,- reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a Window sash adapted to swing on. a horizontal axis located between its upper and .lower ends and adapted to be automatically I i the shoe; Fig. 5 is a cross-section on the line 55 of Fig. a is the window frame having the ordinary sash guides 5 and 0, one guide for the lower sash and the other for the upper sash. The invention is shown as applied to one sash only, but it will be understood that it is applicable to either or both sashes.

Instead of making a sash f ordinary width, I provide a sash oof less width than the distance between guides Z) on opposite sides of the frame, and pivot the sash, on a horizontal axis, midway between its upper and lower ends, as hereinafter described, to shoes 6 slidable vertically int-he sash.

It will be understood thatthe invention may be applied to any ordinary window by taking out the sash and sawing off the sash frame at opposite sides to form the shoes.

Along adjacentcorners of the sash cl and shoe 5 are formed rabbets inwhich are insert T-shaped plates 1, one plate secured to the sash and the other to the shoe.

The above construction, so far as described, is more fully described and also claimed in the patent issued to me November 29, 1904, No. 776,177.

I will now describe the novel subjectemattel of-the present invention.

recessed between its upper and lowerends recess at g and in this recess is inserted the outer'55 plate It and the inner plate 2'.

k is an orifice extending through the shoe from the face thereof-next the window frame to the recess 9, that part of the orifice nearest the recess 9 being of smaller diameter than the "part of the orifice adjoining the window frame. The plate a is provided with a boss j, one part of which extends toward the sash and the other part ofv which. extends into the Z is a plate secured to the face'of the sash adjacent to the recess g; On this plate is formed a pivot pin m which extends within,-

and is turnable upon, the boss 7'. Projecting narrower part of 18 65 beyond'the outer end of the pin m is a projection a, through which extends a cotter pino. i 79 1s a washer surroundmg'the proyectrou n and restin between the cotterpin band; I

the ends of t e boss 7' and pivot pin m.

Secured to or formed upon the outer face of the plate Z, is a series of radially extend ing teeth r. A cup or disk 8 issleeved on the boss 3' within the recess 9' and is pro- 30 vided with similar teeth t engaging the teeth 1-. The flange of the cup 8 is provided with recesses u engaging projections. '22 on the plate. i, thereby preventing the cup from turning, but permitting the cup to have as; l

slight movement toward and from the shoe f 6. Between the plate 2' and cup .9 and surrounding the boss j is a fiat spiral spring w, which normally presses the teeth of cup 8 into engagement with the teeth 1' on the sash.

From the foregoing description it will be I understood that the sash d is turnable upon the shoege. In said turning movement the teeth 1' on theplate Z ride over the-teeth t on. the cup, causing the cup 8 .to vibrate toward and from the shoe 6, but the on cannot turn owing to the engagement 0 proment with the teeth'r, thereby holding sash in the position to which it has. been turned. It will also be understood. that the 1' sash can be moved vertically as desired,l.the ;jlh5 shoes sliding in the window frame guides in .The face of each shoe opposite thesash is i tors Patent is:

what I claim and desire to protect by Let- 1. A sash pivot comprising a plate, a boss on the plate, a cup sleeved 0n the boss and having a plurality of radially extending teeth, means permitting the cup to slide on a the boss but preventing it from turning, a

second plate having a portion turnable in theboss and having a plurality of radially extending teeth engaging the teeth on the cup and a spring between the first plate and the cup normally pressing the cup teeth into engagement with the teeth on the second lplate.

2. A sash pivot comprising a plate, a boss on the plate, a cup sleeved n the boss and having a plurality of radially extending teeth, means permitting the cup to slide on the boss but preventing it from turning, a second plate having a portion turnable in the boss and having a plurality of radially 1 hereunto set my hand, at Philadelphia, Pa.

on this 23rd day of August, 1911.
