1JOSHUA STEVENS, or cuiooPEE --EALLS7 MASSACHUSETTS. Letters Patent No. 61,578, dated January 29,1867;` anteziatet January 1.9, 1867.
IMPROVED SASH 'IAASTBNERL TO ALL WHOM IT MAY CONGERN:
Be it known that I, JOSHUA STEVENS, of Chicopee Falls, county of Hampden, and State of Massachusetts, have invented a new and useful Improvement in Window-Sash Fasteners; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a\k part of this specification, and the letters of reference marked thereon, in which- Figure 1 is a plan view of the fastener.
Figure 2 is a perspective view-of the finger or pawl.
Figure 3 is a perspective view of the cam lever.
Figure 4 is a longitudinal elevation.
Figure4 5 is axview of the cam'with the lever out olf.
Figure 6 is a transverse section through line A B of iig. 7.
Figure 7 is a back elevation of the cylinder, plate, spindle, and crank', .or arrangement for spiral*v spring.
The nature of my invention consists in making a fastener, or cam and catch, which shall so operate that when-the window is raised it shall firmly hold the window at whatever pointit is desired, without the aid of weights or any other of the usual window appliances; and when the window is down it shall firmly hold and securely fasten the window so that it cannot be opened from the outside. v y
To enable others skilled in the art to make rand use my invention, I will proceed'to describe itsiccnstruction and'operation. i y:
`In the drawings, a is the sash-platewhieh is provided-with the projection a', en one side of which is attached the cam-lever I1, and also a nger orpawl, a, one cnd'of which reaches through the plate a into a notch made in the window frame for the purpose of holding the sash in position when down.V The other end c of the finger or pawl passes into a notch, b', made in the upper end of the cam-lever b, in such manner that by rais ing. the handle of the cam-lever b it, shall turn the finger or pawl c on its pivot andrelease it from its notch in the window frame, so as to allow the sash to be raised. When the sash is raised, the handle of the cam-lever b is lowered or dropped, and its weight carries the cam-shaped part e of the lever b into contact with' the Window frame; and the lower part of the cam-shaped part e being further from its pivot than the` upper part, theweight of the sash causes the cam-shaped part e to bind for pinch against the window frame, thereby holding the sash at whatever point it is desired. The handle of the cam-lever may he cut off just back ofthe notch, and for its weight a spiral spring, cylinder, spindle, and crank may be substituted. f is a plate which is fastened to the inside of the sash, and to the back'of the plate j .is fastened the cylinder z', inside of which, and around tho spindle g, is wound a spiral spring, j, one end of which is fastened to the spindle g, either by passing-one end of the spring intoa'small hole drilled 4in the spindle'for that purpose, or by any other suitable means, and the other end may be fastened by passing through a hole in the cylinder,as shown at j. That part of the spindle g is made round to iit the hole l in the platte a', and that part of the spindle g, as shown at L, is made square to fit the hole m in the cam b, g. 5. The cylinder is passed through a hole made for it 'in the sash, and the round part g inserted into the hole Z in the plate a', and thesquare part h-of 'the spindleg inserted into the hole m of the cam b, and the plate f is then turned aroundso as to windv up or t-ighten the spiral spring, and securely fastened to the sash. When this is done the tendency ofv the spring to unwind keeps the cam b iirmly pressed against the window frame, and thus holds the sash at any desired elevation,-as before. The sash may be low- 'ered by moving the handle k of the spindle q slightly to one side. l i Y In this new article of manufacture I can produce a sash fastener which is substantial, not liable to gct out of order, as it is simple in its construction; which can he manufactured at much cheaper ratethan many of the sash fasteners now in commerce, and is perfectly secure, both in fastening the sash when down and in holding the sash when up.
Having thus described my invention,'what I claim as a new article of manufacture, and desire to secure by Letters Patent, is-
The cam b, ngcr or pawl c, and plate a, whether operated by a lever or a crank, all combined and arranged substantially as described. JOSHUA STEVENS.
