T0 ALL WHOM LT MAY CONCERN: l

Be it known that I, W. W. MAUGIILIN, of the city and county of Baltimore, State of Maryland, have invented a new and useful improvement in Sash-Fasteners; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing', making part of this specification, in which Figure 1 is a fromt or face view of a section of the window-frame with my improved fastener applied. v

Figures 2 Vand 3 represent a plan or edge and afront view ofthe fastener for the outer sash, detached; and

Figures 4 and 5 are similar views of the fastener for the inner sash. i

Similar letters of reference denote corresponding parts inthe several figures.

In the various sash-fastening's or latches heretofore in use it has been necessary from their form and construction to let them for their whole length into the jamb or easing, which was mortised or notched out to receive them in such manner as to mar Ythe casing and architecture cuts-ide of the sash-bead, and seriously detract from their appearance and finish, Vand' in some instances the sash-bead has had to be cut nearly or quite away to accommodate the latch. In such eases the sash-bead has necessarily been made a permanent fixture of the frame or casing in such manner as to prevent its removal for the washing of the window or other purpose without considerable dtliculty, involving in most cases the removal of the latch or fastening with the bead.

The object of my invention is to obviate these diihculties and defects, and to provide a nea-t, simple, effectual, and durable fastening, and to this end my invention consists in providing the latch or lever with an otsct or bend underneathI or near the sash-bead in such manner as lto bring it to the surface of the casing inside the sash, thereby avoiding the marring of said casing except where it is hidden bythe sash. And it further consists in the particular lconstruction of the latch provided with'the offset, as hereinafter explained.

To enable others to construct `and use my invention, I will 4describe it with reference to the drawing, in whichv A represents the latch, which may be made or cast in one piece, and B represents a section of a windowframe or casing, illustrating the relation ofthe latch to such casing and to the sash, partition, and outer beads, as hereinafter explained. The latch A is provided at its outer c nd with lugs or flanges, a a', between which the sash slides in being moved up and down, and is expanded in width at to afford a point of pivot to thc frame, and in such manner as to give awide bearing, for the purpose of preventing its wabbliu'g in its seat as the sash is moved up or down. -The point of pivot shouldbe underneath or near the bead next inside the sash to which the latch is applied, so as to bring the point of pivot as near as practicable to the sash upon which it is designed to operate, and in such manner as to make .the latch end of the lever as. short and consequently as quick and etfectual'in its action as possible. The weighting of the said latch end of the lever by means of the lugs or flanges a a makes this arrangement ofthe pivot practicable. At the inner. side or underneath the sashbead the latch is provided with an offset or bead, c, which serves to bring the handle of the lever in front of said bead to the surface of the vjamb or casing in such manner as to avoid the cutting away and mari-ing of the exposed portion of the -jamb land of thc architecture in front of said bead. rIhe latch for the inner and lower sash may, if desired, be locatedjust above said sash in'its lowest or closed position, and so arranged as to'drop into a notchV formedinth'e top of said sash in such manner as to form an effectual lock to said sash when closed.

Y The operation of the latch will be readily understood. `When the sashv is raised the ilanges of the latch coincide with the faces of the beads' between which the sash works, and the moment the sash is released the weighted vand flanged end of the latch, dropping slightly with the sash, instantly clamps and holds the sash rmly against further downwardrmovement. The latch is thus made ,automatic in its operatlon, except when it is desired to lower the sash, when a light pressure of the nger 'upon the handle el serves to release the sash and permits it to bc lowered to the desired point. If desired, the inner flange a may be dispensed with, in which case the downward movement of` the outer ilange a would serve to Vtightly compress the sash against its inner bead and thus hold-it; butin practice I prefer to useboth flanges, as the operation of the latch is thereby rendered entirely independent of the beads, and causes less injury to the edge of the sash upon which it operates.

Having now described my invention, I would stateA that I am aware thatfastenings have been used provided Y with the flanges 'operating in a manner similar to those I have-described, and I theef'ore do not claim such flanges separately considered, but what I claim, and desire to secure bv Letters Patent, is-. v

1. The latch or lever A, provided with .the offset c, arranged to work underneath the Asash-head, and in such manner as to avoid the cutting away or defacing of the jamb or casing outside of said bead, substantially as described.

2. The latch or lever A, provided with the offset c and lugs or clamp a a', arranged and operating as described e Iii-testimony whereof I have herelnto set my hand this 23d day of May, 1867'. I

W.W. MAUGHLIN.
