CURTAIN-HAN GER CLAMP.

Specification of Letters Patent.

Patented Feb. 3, 1914.

Application filed November 4, 1912. Serial No. 729,393.

To all whom it may concern:

Be. it known that I, N ILS EMIL LARSON, a citizen of Sweden, and resident of the borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Curtain-Hanger Clamps, of which the following is a specification.

This invention relates particularly to hangers for positively holding a curtain by clamping without any pins or other adjuncts passing through the same.

One of the objects of the invention is the production of a simple, eflicient and durable hanger which will clamp a curtain between its jaws without injury to the most delicate fabric.

Another object is to provide a curtain hanger having a difierential movement for clamping curtains or draperies of various thicknesses between its jaws.

A further object is to provide a curtain hanger adapted to slide either on a rod or Th between a pair of pole members.

Other objects and advantages will become apparent as the description proceeds.

lVith the aforesaid objects in View, the invention comprises the improvements and combinations of parts hereinafter described in their preferred embodiments as illustrated in the accompanying drawings, and pointed out in the appended claims.

In the said drawings ;Figure 1 is a top plan view of the curtain hanger clamp; Fig. 2 is a front view of Fig. 1; Fig. 3 is a section on the line 3-3 of Fig. 2 and Fig. 4 is a section on the line 44 of Fig. 8.

In these views the numeral 5 designates a head or loop of spheroidal shape and having a pair of integrally formed jaws 6, 7 extending therefrom. These jaws consist each of a fiat portion and an undulated portion as shown at 8, 9 so that they may have a firmer hold or stronger grip on the curtain. The inner faces of the jaws which are smooth have their undulated portions 8, 9 corrugated in gradual curves so as not to injure or impart a permanent set to the fibers of the material clamped between them. The said jaws 6, 7 are stiffened by having their edges provided with right angular flanges 10, 11 which are continuous all the way from one side around the head 5 to the other side. The fiat portions of the jaws below the head 5 constitute together with the flanges 10, 11 outwardly facing recesses 24, 25. Where these flanges pass around the said head 5 they are laid or folded down inwardly thereupon as indicated at 12, 13 by virtue of which the resiliency of the said head is not impaired.

A pair of links 14, 15 pass transversely through suitable apertures in the jaws 6, 7 at a specified distance below the head or loop 5. Levers 16, 17 having integrally formed trunnions 18, 19 journaled in the outer ends of the said links 14, 15, are provided with right angularly offset cam or nose portions 20, 21 that bear oppositely against the jaws 6, 7 betweenthe flanges 10, 11. The said levers 16, 17 lodge in the hereinbefore mentioned recesses 24, 25 when swung into their clamping positions. In this way the jaws are brought up toward each other to clamp a curtain or draperies between them. The inherent resiliency of the loop 5 normally tends to spread the jaws apart. e maximum opening or movement of the jaws is obtained when both levers are horizontal. The cams may be of unequal length. As shown the cam 20 at the left is somewhat longer than the cam 21 at the right hand side, by virtue of which the jaws will move to a greater or less degree depending upon which lever is operated. This is particularly useful when inserting very thin curtains or shades between the jaws in which case both levers should be turned up to bring the jaws close together. For a heavy or thick curtain both levers should be swung down to receive it, after which either one of them may be brought back into its upward position leaving the jaws the proper distance apart to hold the curtain. In this way undue straining of the holder clamp is avoided, besides it protects the curtain from too much pressure. It will be noticed that the major part of the lever travels past its vertical center. This obviates the tendency of the lever to spring back. The upper part of the lever is curved so that it fits snugly in under the spheroidal head 5.

As shown by the dash-and-dot line at A the holder clamp may slide upon a rod or it may be moved between a pair of pole members one of which is indicated at B. The position of the curtain between the jaws is shown by the dash-and-dot lines at C.

While a certain preferred form of this ourtain holder clamp has been described, it will be understood that numerous changes can be made therein without departing from the invention.

Having described my invention, what I desire to secure by Letters Patent and claim is 1. A curtain hanger clamp comprising a head, a pair of jaws extending therefrom provided with lateral flanges forming outwardly disposed recesses, and means operating differentially on said jaws whereby open ings of various widths are obtained therebetween, said means lodging in said recesses when in their clamping positions.

2. A curtain hanger clamp comprising a looped portion, jaws formed therewith having flanges projecting outwardly from their opposite edges, and operating levers connected with said jaws on opposite sides, whereby the aws can be partly closed from either side, said levers being lodged out of the way between said flanges when in clamping position.

3. A curtain hanger clamp, comprising a head, a pair of jaws extending therefrom consisting each of a flat portion and a corrugated portion, flanges following the edges of said jaws, and curved levers for operating the jaws located on the flat portions thereof, said levers lodging between the flanges under said head, and having outwardly turned portions whereby they can be pulled out.

pair of outwardly flanged jaws joined at one end and having suitable apertures adjacent to their flanges, a pair of loose llnks passing through the apertures and cam levers pivoted to opposite ends of said link adapted each to moi e the jaws a different distance.

6. A curtain hanger clamp comprising a looped head, jaws extending therefrom having flanged edges, links passing through said jaws adjacent to their flanges, and cam levers hinged at opposite ends of said links adapted each to move the jaws a diiferent part of the opening'between them, said levers being arranged to swing up entirely under the head between said flanges when in clamping position.

Signed in the borough of Manhattan in the county of New York and State of New York this th day of October A. D. 1912.
