JEREMIAH RILEY, OF NEW YORK, N. Y.

SASH-WEIGHT HOLDER.

SPECIFICATION forming part of Letters Patent No- 314,608, dated March 31, 1885.

Application filed December 13. 1882. Renewed December 20, 1884. (Model.)

To all whom it may concern: I

Be it known that I, JEREMIAH RILEY, of the city of New York, State of New York, haveinvented aSash-Weight Holder, of which the following is a specification.

The object of my invention is to provide an instrument for holding up window-sash weights while sash rope or chain is being put to the sash.

The invention consists of a short metal bar with an arm running out from it at right angles, there being under the arm and attached to the main bar a cog or roughened wheel, of which the axle or shaft, being a little out of center, causes it to act as a cam. To the said axle or shaft, running through the main bar, is a handle or crank to assist in tightening the cam and loosening it from the sash-rope.

Figure 1 is a side elevation of a portion of one side of a window-frame, together with a side elevation of my improved sash -'weight holder applied to the sash-weight cord in the manner of its use, the solid lines showing the position when it is applied to the cord, and the dotted lines showing the position the holder takes when holding the weight; and Fig. 2 is a plan or top view of the holder.

Itake any suitable angle-plate, a b, or equivalent device, and apply an eccentric or cam shaped holding-dog, c, by pivoting it at d to the part b of the angle-plate, so that its face 6, which is serrated for the purpose, will grip and hold the cord f between it and the part a of the plate, the dog being set against the cord, so that the strain of the cord tends to draw the dog in the direction to tighten on the cord by binding it against the plate when the plate is held against moving in the direction of the pull of the cord, as by resting against the face 9 of the window-frame through which the cord runs over the pulley h.

To facilitate the shifting of the dog for setting it against the cord and detaching it therefrom, I have attached a crank, i, to the end of the pivot or shaft of the dog projecting through the part d of the plate, by which suitable leverage is afforded for enabling the operator to detach the cam readily when firmly bound on the cord.

It is to be observed that the pivot or shaft (1 of the dog 0 projects fromand has a bearingsupport at one side only of it, in order to leave 1] the other side free and clear, for allowing the cord to be readily inserted between the cam and plate a and removed therefrom. For lack of a simple device of the sort that can be readily applied to and removed from the cord, it is the common practice to tie a knot in the cord to hold it while detached from the sash for any cause. The knot lodges against the window-frame at 9, over the roller, when the weight strains the cord and draws the knot so tight that it is difficult to untie the knot. Sometimes the cord is made fast to a stick of wood for a holder, which also causes a knot that is not readily unfastened, besides taking more time in the first place than is required to .apply my improved fastener, which is manifestly much more economical of time and labor than any other contrivance for holding the sash-weight cords.

It is to be understood that the plate to which the eccentric dog is pivoted is to be made in the angular form herein shown, in order that it will lodge against the sash-cord pulley and the window-frame in such manner that'jthe plate will not be turned sidewise to the window-frame by the strain of the cord, in which case the cord would be pulled from between the eccentric and the part of said plate against which the cord is clamped. It will be seen by reference to the dotted lines in Fig. 1 that the part a of the said angle-plate bears across the cord-pulley while the upper end of part b bears against the window-frame in a manner to effectually prevent the turning ofthe device, as it would if the dog was mounted on a simple flat base-plate such as is employed for cord-clamping dogs to be fastened by screws or the like means to any permanent support for clothes-line fasteners.

Another advantage of this fastener is that it may be applied to the cord to secure the weight before the cord is disconnected from the sash, and the weight may be held by it until the cord is attached to the sash and the sash put in its place, which cannot be done when the knot is resorted to, for a bow or slip knot shortens the cord too much, and will pull out by the strain of the weight; and a knot requiring the end of the cord to be pulled through the loop must of course be untied before the sash is attached.

I am aware that an eccentric clamping dog has been pivoted on a base-plate fitted for attachmentto a window-frame or other support, and having a lug against which the cord is clamped by the eccentric, for holding clotheslines; but such device will not hold the sashcord for lack of the angle a to rest across the face of the sash-cord pulley, and thereby maintain the device in the position insuring the pull of the sash cord in the direction that causes the eccentric dog to bite and hold se- -curely, but would turn flatwise, so that the stress of the sash-cord would be laterally to the proper direction, and rather tending to cause the dog to release the cord, for the space -must remain sufficiently open at the end of the eccentric dog and the bearing place of the cord on the part a to enable the cord to be 1 put in and taken out laterally, as it cannot be the sash, and to remain until after the cord is again connected.

What I claim, and desire to ters Patent, is-

1. The improved sash-weight holder consisting of the angle-plate a b and eccentric or cam-shaped dog c,in combination, the dog piv; oted to the plate b by an extension of its shaft secure by Letfrom one side onlyand in relation to the part-a, 30

for clamping the cord against it, substantially as described.

2. The improved sash-weight holder consisting of the angleplate at and eccentric or cam-shaped dog c,in combination. the dog piv- 5 oted to the plate b in the relation topart b, as set iorth, by an extension of -its, shalt from one side only, and said shaft having a crank, i, substantially as described.
