SPECIFICATION forming part ofY Letters Patent No. 521,806, dated J' une 26, 1894.

` Application filed November 9, 1.893. Serial No. 490,'418. V(No model.)

, To all whom #may concern:

Be it known that I, LEVIN I-I. MULLIKIN, a citizen of theUnited States,residingatr[`rappe, in the county of Talbot and State of Maryland, have invented certain new and useful Improvements in Sash-Cord Fasteners, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings, and `to letters of reference marked thereon, forming a part of this speciiication, in which- Figure 1,*represents a portion of a sash raili with my improved sash cord fastener applied. Fig. 2, is a longitudinal section thereof. Fig. 3, is a perspective of the fastener detached, and Fig. 4, is a` plan thereof. g

The invention relates particularly to that class of sash cord fasteners which are vlet into a mortise in the edge of the sash and which usually have an overhangin'g top piece provided with a slot to admit the sash cord, and against the lower face of which top plate the cord knot bears; the topplate also having ,inwardly extendingv wings or flanges toprevent lateral or outward movement of the knot. In such fasteners there is a tendencyI ofthe edges of the slot against which the knot bears to out the cord at the knot, and furthermore the sudden dropping of the sash cord weight has a tendency to jerk the fastener out of its mortise.

The object of my invention is to form the fastener with a bore entirely open at its top so that the knot will bear directly against the top wall of the mortise thus giving it a surface Vof wood to contact with, and also to relieve the fastener of all pulling strain exerted bythe weighted cord.

With these objects in view the invention consists in a back plate, and forwardly extending sides having at their outer edges inwardly' extending flanges spacedapart at their adjacent edges to admit the sash cord; the upper edges of said flanges and sides be# ing wholly disconnected to render theupper end of the knot receiving'space or bore within them entirely open at the top, and thereby permit the knot to bear directly against the top wall of the sash mortise and thus prevent formed with forwardly extending parallel sides A2 having at the upper portions of their outer edges inwardly extending iianges A3;

which are spaced apart to permit the entrance of the sash cord C, above its knot c, and the knot may be readily inserted through the Wide space below the flanges A3. The upper edges of the sides A2 and flangesY A34 are wholl y disconnected which leaves the bore or interior opening of the fastener entirely open at its upper end so that the knot will slip freely through the said bore, and come into direct contact with the rounding topI wall of the sash mortise B', across the lower end of the sash cord groove B2. The wooden edges will not cut the cord but will become smooth and'polished. The knot will be'prevented from slipping outwardly by means vof the. flanges A3. The lower portion of the back 4A is provided with a hole through which a small screw d', may be passed to prevent the fastener from pulling out while the cord is being connected therewith, or disconnected therefrom.

The fastener A, is in the form of an oblong body, square in cross section, having rounded ends and provided with a central bore or knot socket open at both ends, and with a longitudinal slot through its front wall; said front wall being cut away below the lower end of the slot for the entrance of the knot.

Having thus described my invention, what I claim, and desire to secure by Letters Pat- Vent ofthe United States, is

As an improved article of manufacture, a

drawn, and consisting in a back, forwardly extending parallel sides and inwardly extendsash cord to come into direct contact with the ing anges at the outer edges of said sides, top wall of the sash mortise, substantially as and spaced apart at their adjacent edges; herein described.

the said sides and Hanges being disconnected LEVIN H. MULLIKIN. 5 at their upper ends thereby rendering the Witnesses:
