WINDOW OPERATING AND LOCKIN'G DEVICE. 5 V

A plication filed May 1 922, Se i l No. 562,045. Renewed January 19, 1925.

To all whom it may concern,"

Be it known that I, JOHN M. PRICE, a citi- Zen of the United States of America, and resident of Des Moines, Polk County, Iowa, have invented a new and useful indow Operating and Looking Device, of which the following is a specification, V

An object of this inventionis to provide improved means for raising and lowering individual window sash and locking the same in any desired position.

A further object of this invention is to provide an improved construction for window operating and locking .mechanism, adapted to be operated by a removable crank, the operating devices being concealed in part and in part located flush with a window frame, thus avoiding projectingelements objectionable in appearanceor likely to become entangled with window draperies.

A further object of this invention is to prov de improved means for ournallng operating devlces,

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is an elevation partly in section illustrating a window frame containing two overlapping sash and means for operating said sash independently of each other. Figure 2 is an elevation of a portion of a face casing showing one of the operating devices and one of the locking devices mounted thereon, on a larger scale than Figure 1. Figure 3 is a cross-section on the indicated line 33 of Figure 1, on an enlarged scale, the locking device being omitted and the crank being shown detached' Figure 4 is" a cross-section on the indicated line 44 of Figure 1, on an enlarged scale, the locking devices being shown in looking position.

For purposes of illustration there is shown a window frame of conventional form, an upper sash 10 and lower sash 11 being slidingly mounted therein in parallel planes in a common manner. Reference hereinafter will be made to various particular elements of the frame construction.

Each sash 10, 11 is formed with recesses in the outer margin of the left stile thereof and anti-friction rollers 12 are journaled in said recesses and are adapted to engage and travel on the adjacent ja-mb ofthe window frame and lessen frictional engagement between said sash and jamb. Grooves are formed-in the outer margins of the right stiles of the sash 10, 11 and racks13, 14 are mounted rigidly in said grooves and have their teeth towardthe adjacent jamb 15 of the window frame. Recesses are formed in theright inner face casing 16 of the windown frame, one above the other, preferably on opposite sides of the horizontal plane of the meeting rails of the sash 10, 11, and holes 17, 18 are formed in the face casing centrallyof said recesses, the holes being of materially less diameter than the recesses. Sleeve bearings 19, 20 are mounted respectively in the holes 17, 18 and are of different lengths, the longer bearing 19 extending across the plane of the sash 11 and substantially to the median line of the sash 10, whereas the shorter bearing 20 extends substantially to the median line of thesash 11. The sleeve bear ings 19, 20 are formed respectively with head flanges 21, 22 which are preferably circular in form and are received and seated in the bottom of the recessesand' secured to the face casing 16 by screws 23. Operating shafts 24, 25 are journaled in and project at both ends from the sleeve bearings 19, 20 respectively and said shafts are formed with heads 26, 27 on their outer ends, which heads are of less diameter than and overlie the head flanges 21, 22. The outer surfaces of the heads 26, 27 preferably are flush with the outer surface of the casing 16. Spur gears 28, 29, preferably of like diameter, are mounted on the inner ends of the shafts 24,

25 respectively and are removably secured thereto by hub set screws 30, 31, said gears respectively abutting the inner ends of the sleeve bearings 19, 20. Thus provision. is made for limiting or preventing longitudinal movement of the shafts 24, 25 in the sleeve bearings. Slots 32, 33 are formed in the j amb 15 at different altitudes and in parallel vertical planes and the spur gears 28, 29 project through said slots into meshing engagement with the racks 13, 14. The

heads 26, 27 of the shafts are formed with angular sockets 34, 35 in alinement with the axes of the shafts and said sockets are adapted to receive selectively an angular head on a hand wrench 37 whereby the shafts and heads thereon may be rotated in either direction manually. Included in the manual ro a i n f the shafts y means of the wrench 37 there is the function of controlling the descent of a sash by gravity. Each head 26, 27 is formed with ratchet teeth 38 adapted to be engaged by a gravity pawl 39 mounted on either of the head flanges 21 or 22, the direction of engagement of the pawl with any teeth being such as to prevent accidental descent of a sash 10 or 11. Each head flange 21, 22 is formed with a series of holes etO arranged in a circular row concentrio with the axis thereof and each head 26, 27 is formed with a single hole 41 adapted to register at times with one or another of the holes 40. Pins 42, t3 are suspended by hangers 4d, &5 from the face casing 16 and said pins are adapted to be mounted in registering holes 40, el 01 the respective operating devices and, when so mounted, serve to prevent movement of a sash, gear and head in either direction, whereby provision is made for locking each operating device against manipulation or accidental rotation and holding the sash in any position in which it may be placed manually.

The head flanges 21, 22, screws 23, heads 26, 27 and pawls 37 may be finished in any desired manner to harmonize with the finish given to the face casing 16. The arrange ment of the heads of the operating devices and their supports in the recesses in the tace casing 16 avoids objectionable appearance and danger ofentangling 0t draperies with said elements. The crank 37, pins 42, 4:3 and hangers 44, 45may be selectively or entirely removed when not desired for use and stored extraneous t0 the window.

recess and ahole at the center thereof and jamb formed with a slot, of a sleeve bearing mounted through said hole and formed with a head flange seated in said recess, a shaft journaled in said sleeve bearing and formed with a i'atcheted head overlying said head flange and contained within said recess, a gear removably mounted on said shaft, abut-- ting said sleeve bearing and extending through said slot, a pawl pivoted on the head flange of said sleeve bearing and adapted to engage the ratcheted head of said shaft, and means for rotating said shaft.

2. In a device of the class described, the combination with a casing formed with a recess and hole at the center thereof and a jamb formed with a slot, of a sleeve bearing mounted through said hole and formed with a head flange seated in said recess, a shaft journaled in said sleeve bearing and formed with a head overlying said head flange and contained within said recess, a gear mounted on said shaft, abutting said sleeve bearing and extending through said slot, said head flange being formed with a series ot-holes, the head being formed with a hole adapted to register therewith, a pin adapted to be mounted in registering holes, and means for rotating said shaft.

Signed at Des Moines, in the county of Polk and State of Iowa, this 15 day of April, 1922.

JOHN M. PRICE.
