WINDOW.

SPECIFICATION forming part of Letters Patent No. 656,130, dated August 14, 1900.

' Application filed November 6, 1899. Serial No. 735,866. on model.)

To all whom it may concern.-

Be it known that LARCHIBALD M. WHIPPLE, a citizen of the UnitedStates,residing at North Adams, county of Berkshire and State of Massachusetts,have invented certain new and useful Improvements in Windows, of which the following is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this I 5 specification.

Similar characters refer to similar parts in the several figures Figure 1 of the drawings is a front side elevation of my improved window. Fig. 2 is a vertical section of the same, taken on the broken line 2 2 in'Fig. 1. Fig. 3 is a top plan view of the upper end of the sash. Fig. l is a side view of the slat for closing the open slot in the upper rail. Fig. 5 is a horizontal section taken on the broken line 5 5 in Fig. 2. Fig. 6 is a similar section with the glass and packing. removed. Fig. 7 is a similar section showing a. modified form of packing groove or rabbet.

The objectof my invention is to alford a stronger and more ornamental and durable means for glazing 'windowsashes and by which the glazing can be more easily accomplished and removed without the necessity 3 5 of skilled labor.

Heretofore the glass has commonly been secured in window-sashes by means of metal points, such as triangular pieces of sheet-tin, and putty. Extreme care and skill are re- 40 quired lestthe metal points,beingapplied only at widely-separated intervals, should crack the glass and lest the putty should present an uneven and objectionable appearance. Expansionand contraction of the parts due to changes in temperature are liable to increase the pressure of the points upon the glass sufficientlyto crack it.

In factory buildings and other buildings or structures where the windows are subjected to a considerable or continuous vibration the putty soon disintegrates and falls away from the sash as heretofore constructed, which not only destroys the tight joint between the glass and frame, but puts more strain upon the metal points, which soon yield and allow the glass to be broken. My improved construction overcomes these defects, doing away'with the metal points and permitting the use of any desired packing. I provide the stiles and rails of the sash with channels adapted to receive and loosely fit the edges of the glass, the channel in one of the stiles or rails (preferably in the top rail) being extended through the rail .to form a. slot opening eXteriorly of the rail and communicating therethrough with the glass-channels in the adjacent sides of the frame, through which slot the glass can be easily slid into the sash and into the channels made to receive it. Along one edge of the channel in the respective parts I provide a rabbet or groove adapted to receive a cord packing which is forced in between the outer wall of the groove and the glass, thus not only securely fastening the glass against lat particular kind of packing nor to the method of making same.

Referring to the drawings, the numeral 1 represents the stiles, and 2 the rails, of the window-sash, which may be put together and secured "in the usual manner. The rails and stiles are each provided with a channel 3, adapted to receive and loosely fit the glass 4, as seen in Figs. 5 and 7. The channel is extended entirely through the top rail to form the open slot 5, through which the glass is inserted in the sash to the position shown in Fig. 2. After the glass is inserted the open slot may be-closed and the glass held in place by the insert-ion of a slat 6, as shown in Fig. 2. After the glass is inserted the cord packing 7 is inserted in the rabbet or groove 8, so as to force the glass over against the opposite wall of the channel and make a tight joint between the glass and sash.

The rabbet or groove may be right-angular in cross-section, as shown in Figs. 5 and 6, or curved and undercut, as shown in Fig. 7. By having the groove undercut or coped out the packing is held more securely in place; but either form or any approximate form will be found amply sufiicient to hold the packing against displacement.

It is obvious that the channel is not obstructed by or made to receive anything but the glass, so that the glass if cracked or broken can be easily removed and another inserted through the open slot, it only being necessary to remove the slat 6 and the packing-cord, which can be easily replaced as well as removed.

By having a distinct channel for the glass .and groove for the packing, with the channel extended more deeply into the sash-frame than the groove and the groove opening laterally into the channel, I secure many advantages.

The glass is not wholly dependent upon the packing for support, and if the packing were entirely removed the glass could not fall from the sash nor have any considerable movement.

The glass forms one side of the packinggroove, and the outer wall of the groove is located in direct opposition to the glass, but at a distance from the edge of the glass, so that none of the packing material can come in contact with either the edge of the glass or the bottom of the channel, which is an important feature, especially if the packing material is of a sticky or adhesive nature, as the edge of the glass and the channel are thus kept at all times entirely unobstructed and free from packing material, which would tend to clog the narrow channel and interfere with the insertion and removal of the glass.

Only a small quantity of packing is necessary if properly applied and supported, and in the present construction the packinggroove can be made as shallow as desired to receive the comparatively-small quantity of packing that will be found necessary, while the glass-channel can be made of any depth desired and the glass can be thus deeply seated in the frame.

The packing can, if desired, be almost wholly concealed within its groove and where exposed will be hardly noticeable, particularly if painted similarly to the sash-frame.

The wall of the glass-receiving channel on the side opposite the packing-groove is preferably extended to approximately the same distance from the bottom of the channel as the opposite wall of the packing groove, whereby said extended channel-wall will support the body of the glass at a distance from its edge in direct opposition to the packing.

I am aware that weather-strips and the like have been applied to a sash-frame in contact with the glass and that it has also been proposed to secure a rubber or other packing cord in contact with the glass by means of grooved metal strips seated in slots cut in the frame of the sash, and I make no claim to either of such constructions, in none of which did the sash-frame have a distinct glass-receiving channel extended more deeply into the frame than the groove or seat for the packing. Furthermore, the construction employing the metal strips above referred to could not be applied to a frame having narrow rails nor to the mullions, as the narrow rail or mullion would be almost or quite cut through by the grooves necessary to receive such metal strips.

Most or all of the prior attempts to improve upon the common method of securing glass in windows have been confined to the formation of a joint between the outer side of the glass and thesash-frameby actual contact of the glass with the wood.ofthe frame, the pressure being applied by packing-strips upon the inner side of the glass. A tight joint cannot thus be formed on account of the irregularities in the surface of the glass.

In myimproved construction it is more particularly intended to locate the packing on the outerside of the glass, and thus, by using an impervious plastic packing that will conform to the irregularities in the glass, to secure a tight joint that will be proof against air and water without injurious pressure upon the glass.

What I claim as new, and desire to secure by Letters Patent, is-- 1. In a window, the combination with the sash-frame having formed therein a glass-receiving channel and a packing-groove, opening into said channel, said'channel being extended more deeply into the frame than said groove; of a glass located in said channel; and packing located in said. groove, in contact with the glass, substantially as described.

2. In a window, the combination with the sash-frame having formed therein a glass-receiving channel and a packing-groove, said channel being extended more deeply into the frame than said groove; of a glass located in said channel; and packing inserted in said groove and inclosed between the outer wall of the groove and the body of the glass at a distance from its edge, substantially as described.

3. In a window the combination with the sash-frame having formed therein a glass-receiving channel on three sides of the glassopening, a slot in the fourth side of the frame opening exterior-1y thereof and communicating directly with said glass-channel, and a packing-groove on all sides of said glass-opening, said channel being more deeply extended into the frame than said groove; of a glass located in said channel in position to close said glass-opening; means for closing said slot in the fourth side of the frame; and packing inserted in said groove, substantially as described.

4. In a Window, the combination with the sash-frame having formed therein a glass-receiving channel, and 'a packing-groove, said channel being extended more deeply into the frame than said groove, and the opposing walls of said channel and groove being extended to approximately the same distance from the bottom of said channel; of a glass located in said channel; and packing located in said groove opposite the extended portion of the channel-wall,substantially as described.

In testimony whereof I have hereunto set my hand this 28th day of October, 1899.
