To all whom, it Wha/y concer-71,:

Be it known that I, EDWIN WV. HUMPHREYs,

a citizen of the United States, resding at Chicago, in the county of Cook and State of Illinois, have invented a certa'n new and useful Improvement .in Vindows, of which the following is a specification.

My invention relates-to windows wherein the sashes are vertically movable; and the object of the invent'on is to provide apparatus whereby the sash may be temporarily swung into the room, so that both sides may be washed from within the room, thus eliminating the danger attendant upon washing windows from the outside of the budding.

I accomplish my object by mea'ns of the apparatus illustrated in the accompanying drawings, in which- Figure l is a perspective v.' ew of a window, showing the window-frame and the upper and lower sash, the lower sash being swung into the room by the aid of my apparatus. Figs. 2 and 3 are horizontal sectional views, Fig. 2 being taken through the lower sash, and Fig. 3 through the upper sash. Fig. 4 is a fragmentary view looking in a direction parallel with the pane of glass and showing the hinges and hinge-supports whereby the lower sash may be temporarily swung into the room. Fig. 5 is a horizontal sectional view taken on line 5 5, Fig. 4. Fig. 6 is a diagrammatic view showing the preferred manner of arranging the weight and window-cord. Fig. 7 is a general perspective view of the windowframe, showing the rear upper sash in lowered position and swung into the room. Fig. 8 is a fragmentary view showing the manner in which the upper sash descends upon and is supported by a pivot-bearing near the bottom of the window-frame. Fig. 9 is a fragmentary sectional view of the part shown in Fig. S, the section being taken on line 9 9, Fig. 8. Fig. 10is a fragmentary view, in hori- Zontal section, showing the construction of the disappearing hinge whereby the upper portion of the upper sash is supported when in lowered position to be swung into the room. Fig. 11 is a sectional view of the parts shown in Fig. 10 looking in the direction of the arrows on the line 11 11, Fig. 10. Fig. 12 is a detail view in perspective of the hinge attachment for the upper part of the upper sash shown in section in Figs. 10 and 11.

Similar letters refer to similar parts throughout the several views.

In some respects the constructions of the upper and lower sashes are necessarily different, or at least their relationships to the window-frame are somewhat different, especially if the parts be designed with reference to the expedient of swinging them into the room from apoint near the bottom of the windowframe, and for this reason the apparatus for swinglng the lower sash is dffferent from the apparatus for swinging the upper sash, and the parts must be necessar.ly described separately. Consequently the apparatus for operating the lower and front sash will first be described.`

Referring more especially to Flgs. 1 to 5, inclusive, a represents the lower sash, which is adapted to slide vertically in the guideways of the window-frame b. At the front edge of said guideway is the strip b2, which forms the forward edge thereof, and at the rear of said guideway is the strip b3, which forms the rear edge thereof. In order to permit the sashes to swf ng inwardly into the room, a portion b4 of strip b2 on one side of the frame is made removable and adapted to be removably held in place by means of the handoperated catches b5. Under normal conditions, of course, the removable strip b4 remains in position, as shown in Fig. 2. At the lower portion of the frame is a sill b, which is adapted to lie in front of the lower edge of the sash when the latter is in its normal lowest position.

Both the upper and lower sashes are counterbalanced by means of sash-weights c acting upon the window-cords d, which run over the pulleys d, located near the upper portion of the window-frame, in the ordinary manner. For reasons hereinafter mentioned it is desirable to reduce the travel of the sashweight relatively to the amount of cord traveling over the pulleys d, and this is accomplished by mounting a pulley c in the sashweights and extending the cord around said pulley and up to a fixed point 117 in the window-frame. ,By tins arrangement the sashweights. travel only half the d'stance that they would if directly connected to the cord in the ordinary manner. This arrangement is best illustrated diagrammatically in Fig. 6.

Attached to sash a at the pivot edge thereof are hinges, which consist of two leaves e and e', the leaf c being permanently attached to the sash and the leaf c having a raised head c2 formed thereon in such manner as to be engaged by the plates f, permanently secured to the adjacent strip b2. As best shown kin IOO Figs. 4 and 5, said plates have slots f therein7 the lower portion of the slots being of sufficient dimension to receive the head e2 of the hinge-leaf e. The upper portion of said slots f are narrow, and thereby prevent the withdrawal of head e2. .A dog f 2, pivoted to platef, is adapted to contact the lower edge of the hinge-leaf e to prevent the lowering of the head e2 from the upper narrow portion of the slot. As a result of this construction when sash a is lowered to the proper point the leaf e may be swung so as to bring the head-e2 into the lower portion of slotff Then upon raising the window-sash a slight distance the head e2 'may be brought to the upper portion of said slot, where it will be retained. The subsequent lowering of the sash will be prevented by the dog f2 on the upper one of the plates f, and as a result the window-sash will be temporarily hinged to the window-frame. Under ordinary circumstances it will be suflicient to provide only one of such dogs, and for convenience this has here been placed upon the upper one of the two plates l/Vhen the hinges are not in use7 the leaves e2 may be swung against the leaves e, where they will be practically out of the way. It is one of the advantages of this construction that the plates f do not project in front of the surface of strip b2, they being countersunk into said strips and a space being provided in the strip behind the plate for receiving the heads c2. As it is impractical ble to have the sill be removable, the plates f are so located in the strip b2 that when the hinges e e are in operative connection with said plates the lower edge of the window-sash will clear the window-sill. It is proposed also that the plates f shall be so located that the heads e2 will enter the slot f when the window-sash is in its normal lowered position.

As window-sashes are rather heavy, especially if they contain plate-glass panes, and as it is desirable to employ hinges and attachment-platesf of small dimensions, so that the parts shall be unobtrusive, it is desirable to afford means for assisting in the support of the outer free edge of the window-sash when the latter is swung to open position. I accomplish this by providing a hook g at a convenient point near the upper end of the frame close to the guideway b, said hook being adapted to support a pulley-block h, over which the sash-cord d may run.

In the operation of the device as thus far described the operator first takes a pulleyblock 7L, with which he is provided, and hangs it on thehook g, atthe same time drawing out the cord d, which connects with the outer free edge of the lower window-sash, passing it over said pulley-block in the manner shown in Fig. 1. He then swings the hinge-leaves e so that the heads e2 thereon will pass into the plates Then after removing the strip b4 he raises the window-sash a slight distance until he is able to throw the dog f 2 to operative position below the hinge-leaf e. The leaves e will then be in positive engagement with the plates f, and the sash may be swung to open position into the room, as illustrated in Fig. 1, the cord CZ supporting, to a greater or less extent, the free swinging edge of the Window-sash. The swinging movement of the sash will not be prevented by cord d, for the reason that it leads to a point approximately in the line of the axis of the hinges e e. When it is desired to return thesash to normal operative condition, it is swung back to its usual position in the frame, the pulleyblock h is removed, and the cord allowed to assume its normal condition. The dog f2 is thrown back, the window-sash is lowered until the heads e2 may be disengaged from the plates f, and nally the strip b4 is replaced in its usual position in the frame.

The object in having the sash-weight c hung on a pulley c is to arrange for a sufficient amount of cord d to draw the same outl over the pulley-block without necessitating too great an amount of travel of the sashweight, for it will be understood that it is desirable that a window-sash weight shall not have a travel greater than the height of the window-frame.

Referring now to the apparatus for temporarily supporting the upper sash 'i to permit it to be swung into the room, attention is called more-particularly to the figures of the' drawings, excluding Figs. 4 and 5. The upper sash i, which travels in a plane behind sash a, is similar in most respects to sash a, except that it is a trifle narrower, being adapted to lit within the guideways y'. Said guideways lie a slight distance inside of the guideways b in order that there may be no necessity at the lower portion of the windowframe for the strips b3, which occur at the upper portion of the frame for guiding the upper sash and keeping out the weather. The omission of the strip b3 at the lower portion of the frame permits the upper sash to be swung forward at the lower portion of the frame without the necessity of the employment of a removable strip, as is the case with the lower sash. It is desirable in many cases to shorten strip b3 at the right side of the window-frame and for appearances place the remaining portion t7 on the upper sash itself, as illustrated in Fig. 7. By this contrivance when the upper sash is in normalfraised position it will not be evident that the guide-strip on the right side ofthe window-frame is any shorter than the strip on the left side thereof. The shortened strip b3 will permit sash/tl to clear the bottom of the strip when the sash is being swung into the room.

Fastened toV the bottom of the'upper sash is a socket-plate t', adapted to lit over and bear upon the pivot-post f, permanently se- IOO TIO

cured in the window-frame beneath sash i. The partsare so arranged that when sash L is lowered to a point near the bottom of the frame-plate 'i' will come to a bearing on post It and become pivoted thereon. This in a simple manner takes care of the pivoting or hinging of the lower portion of sash t', and the same result is a ccomplished for'the upper portion of sash i by means of the devices shown in detail in Figs. 10 and 11. Referring to the last-mentioned iigures, m is a yoke having two horizontal arms which are vertically apertured, so as to receive the pivot-bolt n. A nut or shoulder n is placed on bolt n for retaining the same within yoke m and at the same time permitting a limited vertical movement of said bolt in said yoke. Bolt n and its yoke are located at an elevation such that they'will be adjacent to the top of the upper sash when the latter is lowered to a bearing upon the post k. The yoke is supported in the window-frame preferably by means of two plates o o, having inwardly-projecting flanges 0 o for retaining the upright piece m of the yoke m. Said plates are preferably so formed that they constitute a continuation of strip b3 1n the manner best illustrated in Figs. l, 7, 10, and 1l. The strip b3 is cut away at this point, so as to form a recess or chamber bs, (see Fig. 10,) and the construction is such that the yoke m is horizontally movable, so that it may be entirely inclosed within the plates o or may be projected forward into operative position, as shown in Figs. l() and 11, the object being to place the yoke out of the way and practically out of sight when not in use.

The pivot-bolt n is vertically movable in the apertured yoke-arms, so that when the yoke is out in operative position the bolt may drop a slight distance, the amount of drop being limited by the nut or shoulder n.

A. hinge is provided consisting of the leaves p and p', the leaf p being rigidly secured to the upper portion of the upper sash and the leaf p/ being adapted to swing so that it may lie either adjacent to the top of the sash or project horizontally in front of the same. In

this last-described position, which is shown in Fig. 1l, said leaf p', which is apertured, may receive the bolt n and be thus hinged upon said bolt as an aXis.

In operating the upper sash the lower one is i'irst swung into the room out of the way of the upper one. The upper one is then lowered until plate i comes to a bearing on post k. The hinge-leaf p is then swung forward to horizontal position, and after the yoke m is brought forward the bolt n is permitted to drop into the aperture in leaf p', the parts then being in the relationship shown in Figs. 1() and 11. Thus both the u per and lower portions of the upper sash wi l be pivotally supported, and as yoke m lies above the leaf p the sash cannot be accidentally raised off from the post r,nor can the leaf p become disengaged from bolt n until said bolt is actually raised by hand up free from said leaf. The bolt is held down by gravity, and consequently there is practically no possibility of the upper sash becoming accidentally unhinged. The window-cord of the upper sash may be drawn out to form an auX- iliary support for the free edge of said upper sash in the same manner as for'the lower sash and as illustrated in Fig. 7. The upper sash may be freely swung inward because of its smaller width and the absence at the lower part of the frame of the strip b3.

There are three advantages in the employment of the post k and plate i', as shown. In

the first place, the post lies in the path of the sash and the plate i is adjusted by merely pulling the sash down until it cornes to a bearing. In the second place, the height of the post remains permanent and may be predetermined to stop the sash at such height as to clear the window-sill in swinging, and in the third place the top of the post, although exposed to the weather, is high enough not to become clogged with ice or snow` Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a window the combination with the frame and vertically-movable sash of a plate attached to the window-frame, said plate having a slot therein larger at one end than at the other, a hinge attached to the sash, said hinge consisting of two leaves one of which is free from the sash and the said free leaf having a head thereon of such dimensions as to readily enter said slot at the larger part thereof and too large to be withdrawn from the smaller part thereof and a dog attached to the plate and adapted to retain the hinge with its head in the narrow part of said slot.

2. Means' for temporarily hinging a window-sash to its frame said hinging means including an apertured plate hinged to the sash whereby it may when not in use be folded against the sash, a bolt adapted to engage said apertured plate to act as a pivot, and a member m for carrying said bolt, said member m being secured in the window-frame and adapted to slide in a direction parallel with the surface of the sash when in normal position, and said member 'm being adapted to disappear in the window-frame when not in use.
