JNO. F. PEABODY, OF SALEM, MASSACHUSETTS.

SASH-SUPPORTER.

Specification of Letters Patent No. 22,821, dated February 1, 1859.

To all whom it may concern:

Be it known that I, JOHN F. Pnuaonr, of Salem, in the county of Essex and State of Massachusetts, have invented an Improved Mode of Applying a Sash-Supporter to its Sash and indow Frame; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings.

In such drawings, Figure 1 denotes a front view of a window frame and sash having my improvement. Fig. is a horizontal section taken through the rack bar.

My invention is specially designed for windows of railway passenger cars, and in making it I have sought to obtain such a sash supporter or such an application of one, that its construction and mode of operation would be apparent to any person on a glance of his or her eye 011 it.

The various kinds of sash supporters which are moreor less concealed within the sash and its frame, or in a boX or case applied to either are generally objectionable as they are either more or less destructive to the frame or sash or are so covered as to render it difficult for their mode of action to be understood by passengers. Furthermore, when they operate by spring pressure or friction against the jamb or groove they are apt to either cause the window sash to stick too hard in the frame (particularly during damp weather) or to slide too easily.

In carrying out my invention I employ a lever catch and a toothed rack. The former I apply to the sash on its inner side, while the latter I arrange against the inner side of the sash and fasten to the frame, so that the said rack shall not only serve to maintain the sash within the groove of the frame, but in connection with the catch operate to hold it at any desirable height in the frame, both rack and latch being in plain sight of a person, whenever he may attempt to raise the sash from its inner side.

In the drawings A, denotes the window frame, and B, the lower sash, a, and Z), being the two grooves in which such sash is held and travels while being either elevated or depressed. A gravitating lever catch G is applied to the inner side of the sash, and turns on a screw (l, the longer arm 6, of the catch being heavier than the shorter one, f, which acts with the teeth of the rack bar D, which is arranged against the sash and so as to constitute the inner boundary of the groove (4, and be entirely outside of the said groove. The said rack bar is fastened to the jamb g, by screws 7b, 72, h, and should be made of metal. The rack bar thus answers a twofold purpose, that is, it holds the sash in the groove, and in connection with the lever catch supports the sash when raised in the groove. Its arrangement with that of the catch enables their construction and mode of operation to be readily understood by any person as soon as he may cast his eye upon them. The utility of such arrangement, therefore is one, which not only is great but readily apparent;

I do not claim the invention of a rack and a catch; nor the arrangement of a rack or its equivalent in the grooved jamb of the window frame so as to be covered by the sash while being raised, whether such rack be placed on the bottom of the groove and against the edges of the sash or against the rear side of the groove and against the rear or outer side of the sash, but,

lVhat I do claim is My improved application or arrangement of the rack bar, D, with reference not only to the groove, a, of the window frame, but to the inner side of the sash, B, and to the catch applied thereto as describedthe rack bar under such arrangement not only being in full view with the catch at any altitude in which the window sash may be placed in the frame, bht operating notonly to support the sash at such altitude but to maintain it within the groove 64, as specified.

J. F. PEABODY.
