WINDOW.

Specification of Letters Patent.

Patented Aug. 6, 1907.

Application filed September l0, 1906. Serial No. 333,881.

To all whom it may concern:

S. LEAKE, citizens of the United States, residing at Chicago, in* the county of Cook and State of Illinois, have invented new and useful Improvements iny Windows, of which the following is a specification.

The invention relates to windows and particularly to that class of windows in which the sash es are arranged to swing inwardly as well as to slide up and down.

The invention has for its object yto provide new and improved constructions and arrangements in the attachment and balancing of the sashes.

The invention also vcontemplates certain other new and improved constructions which will be made apparent by the following description: f

The invention is illustrated in the accompanying drawings wherein Figure l is an elevation of a window taken from the inside, parts of the frame being broken away; Fig. 2, a sectional view on line 2 2 of Fig. l.; Fig. 3, ahorif/.ontal-sectional view of the window and its casing, the sashes being shown in a different position from that oi the previous figures; Fig. 4, a vertical sectional view on line 4 4 of Fig. l; Fig. 57 a cross section on line 5 5 of Fig. l; Fig. 6, a cross section on line 6 6 of Fig. l; Fig. 7, a cross section on line '7 7 of Fig. l.;

Fig. 8, a detail of the hinged guide with its fastener; Fig. 9, an elevation of one of the sliding tongues to which the window sashes are attached; Fig. l0, a cross section on line |.0 l0 of Fig. 9, Fig. Il, a longitudinal section through one of the sash balance pulleys, and Fig. 12,-a section on line 1.2 12 of Fig. Il. l

Like letters of reference indicate like parts in all the drawings. y

The various parts of the window frame, which is of ordinary construction, are indicated by the letters A, A.

B represents the jamb on one side of the window and B1 the jamb on the other. The window frame is preferably constructed so that a recess Bl is formedA back of the jamb B. There may also be a recess B3 back of the jamb B1. The window is shown as having two sashes7 an upper sash C, and a lower sash C1. These sashes are constructed and attached to the frame of the window so as to slide up and down in the customary Way and also to be capable of being swung inward into the room. The arrangement is the same with respect to each of the sashes so we shall confine the description to one sash.

On the jamb I3 are strips D, D,'one for the upper and one for the lower sash. These strips are formed with longitudinal slots D1 having inner enlargements D2. The strips may be made of metal or they may be made ol' wood, inwhich case they can be formed in two parts as shown. lf of wood they will preferably be thoroughly soaked in oil. The slot D1 with its enlargement D2 is designed for a sliding tongue piece E, shown in detail in Figs. 9 and l0, and which consists of a shank E1, a cross piece E2, and a cylindrical extension E3 which will preferably be formed by turning the shank over upon itself, as is shown in the cross section of Fig. 10. The sash C is hinged to this sliding tongue E. We have shown two hinges for each sash, one of which is illustrated in detail in Fig. 6. It consists of a sheet of metal F having a cylindrical bend F1 to extend around the part E3. The plate Fis secured to the front of the side rails C2 of the sash by means of grooves F2 F2, and has a right angle extension I"3 beyond the curved part F1 which passes through a slot E4 in the sh ank E1 of the tongue piece and is fastened by means of a screw F 4 to the side rail C2. Any desired form of hinge might be adopted but the above we have found to give very secure attachment. It will be undersood that all of the hinges may be constructed in the same manner.

The sashes are designed, either to slide up and down or to be swungl inwardly on their respective tongue pieces E, E as pivots. It is, therefore, necessary to provide on the other side of the window a connection between thesash and frame which will permit the sliding of the sashes upon the frame and also their disengagement from the Window frame when they are to be swung inwardly. It is important that this connection be a snug one so as to keep out Wind and cold and prevent rattling. To this end we provide each oi the sashes with a removable guide piece adapted to slide in the window frame but capable of being retracted in case the sash is to be opened inwardly. This guide and its attachments are illustrated particularly in Figs. l, 3, 7 and 8. It consists of a strip or plate G hinged at G1 to the right hand side rail C3 of the sash and bent around at G2 so as to conformto a groove BA1 in the -jamb B1. There will, of course, be two of these grooves, one for each of the sashes. The part G2 of the guide is preferably formed with a rib G3 and is slotted at G4 to receive the loop G5 of a clip G to which is pivoted at G7 a latch GS having slots GJ G9. The latch extends through a slot G10 in the flange G11 of a plate G12 which is secured by screws G13 G13 on the front of the side rail C3. In Fig. 8 the guide is shown as locked in the position it takes when in engagement with the jamb of the window. When the sash is to be swung inwardly the latch Gs is lifted, drawn inward toward the window pane until the other of the slots G9 is engaged by the flange G11. The guide will then be free of the jamb so that the window may be swung on the partJ E3 as a pivot as shown in Fig. 3. It will be seen that the connection between the sash and the jamb is a very close one, but one, however, which permits perfect freedom in moving the sashes up and down.

The sashes may be balanced in any desired manner. We have shown, however, a preferred method oi sash balance construction involving several innovations and which is suitable perhoaps to other forms of windowr than the one we are describing in this specification,

but which is particularly adapted to the construction herein shown. This construction of sash balance contemplates balancing the sashes, one against the other, on a vsingle 'cord and by the use of a single weight. While this arrangement is not in itself new, the construction here shown involves certain improved devices and arrangements obviating defects incident to this method of balancing the sashes of a window.

The cord H, attached at one end by means of a split ring H1 to the lower sash C1, passes from a small deflecting wheel J around a pulley K, then down around a pulley L in a block L1 to which is attached the weight M, up over a. second deflecting wheel J1, around a pulley K1, and then to the upper sash C to which it is attached by a split ring H2.

The attachment to the sashes may be made in any desired manner. We have shown in the drawings a clip N bent at Nl to embrace the part E3 of the sliding tongue E, and pinned thereto by the pin N2. This clip has the extension N3 with the perforation N4 to receive the split ring on the cord H. It will be understood that we use the word cord in general to indicate any rope, chain, or other means for supporting the sashes.

Where the two sashes of the window are balanced by a single weight it has been found that a quick movement of one of the sashes may disturb the position of the other. To lessen this effect we prefer to construct and arrange our pulleys in a peculiar manner. One or more of the pulleys are preferably constructed so that there will be a considerable friction between the rotating part of the pulley and its axis'or core. The pulley will, therefore, be somewhatsluggish, tending to brake the action of the movement of the sashes one upon the-other. This effect is increased by the use of deflecting wheels or pulleys which, moreover, kgive a compact construction. We have'shown, in Figs. ll. and 12, a preferred construction of pulley and deflecting wheel, these drawings showing the construction, for example, of the pulley K and deflecting pulley J.

These pulleys are mounted in a block which is set into a slot in the jamb B. The block is preferably made in two halves, the line of jointure being indicated at X, X. The block, when the halves are assembled con sists of a front plate K2 which has a perforation K3 for the screw K4 by means of which it is secured to the jamb B. Integral with the two halves of the plate K2 are backwardly extending plates K5 which have the circular flanges K6 K6 forming a core or axle for the pulley wheel K7 which extends through a slot in the plate K2. The plates K5 have the integral extensions K8 below the core flanges KG K( and between the plates at this point is the axle J2 of the deflecting pulley J. The two halves forming the block of the pulley carry lugs K9 K9 perforated to receive the rivet Km by means of whichthe assembled parts are held together.

I wish` it to be understood that l do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to any person skilled in the art.

The use and operation of our window will perhaps have been made sufficiently clear by the foregoing. To recapitulate, .it will be sceen that the sashes are hinged to sliding members which preferably have a long bearing in the window frame. The sashes, together with these sliding members fnay, therefore, be pushed up and down in the ordinary way so as to open or close the window at top or bottom. When it is desired to swing the sashes inward, for example, for the purpose of cleaning the window, the guide pieces G may be retracted and locked in the position shown at the right hand side of Fig. 3. The sashes canthen be swung inward with perfect freedom. This construction, it will be seen, is very simple and economical. The sashes are at the same time tight enough to keep out the weather and yet may be freely moved. The sashes,` it will be seen, are balanced one against the other by a single cord and through the instrumentality of a weight which may be very much less, perhaps less than half the weight of the two sashes. By the use of the pulleys of our construction arranged as above described, this novel method of balancing the sashes is perfectly practical.
