narran CREEK, nrrorirfmivV `Application mea. september en ,"ieze.fseriai"fiiqfeeaeee fl" This invention is an improved window sash fastener adapted tobe securedtoV thek Window frame at right angles to lthezsliding sash, said fastener being capable of an eccen-V stric clampingaction against the. sash; and the principal objects of the invention are to provide a window sash fastener which will not mar the sash.; which may be readily enf gaged and will be very effective inV holding- 10 the sash in any adjusted position; which will prevent rattling of the window and will'prevent the window from being` raised from the outside; and which is economica-l to manufacture and is easily installed. n

Further objects-"of theinvention are to providea'window sash fastener or lock the operationof whichvdoes not depend upon any spring or' other parts either attached to the fastenerror to the window sashforV winf dow frame; also to provide a-fastener the operation of which does not dependuin any way upon any particular type ofwindowV sash, but which can be attached or usedwith any ordinary window sash without altera- 25 tion thereof; also to provide a. fastener the operation of which Vis entirely Vautomatic except that when'the Window is being raised or lowered the fastener must be held out ofV engagement with the sash, and which iinmediately upon releaseV Awill wedge litself against the sash and? `hold it stationary inf anyposition desired. f y

n Other minor objects of the invention be hereinafter set forth. Y y 35' I will explain the invention'with reference to the accompanying drawing which` lillustrates one practical embodiment thereof to enable others to adopt and use the same ;f ,Y and will summarize in the claims thenovel features vof construction,"and novel coinbinations of partsffor which protection" is desired.V Y VIn said drawings: p n 1 Fig. 1 is a perspective view ofa portion of a window showing my'- novel sash fastener secured to the side of the window .frame atright angles to the sliding sash. n,
