URTAIN.

Specification of Letters Patent.

Patented Nov. 23 till .3

Application filed January 9, 1914. Serial No. 811,166.

ing said radiator to prevent an ex'cessive.

cooling of the. water in the radiator.

One of the objects or" the invention is to produce a shield which may be adjusted along the face of the radiator to vary the area of radiator surface exposed to the cooling action of the. cold air currents.

Another object of the invention is to provide a radiator shield which maybe adjusted upwardly from the bottom of the radiator, thereby. providing an adjustable closure adapted to close the lower portion of the radiator while the upper portion of the radiator is open to permit the circulation of air thcrethrough. This is an important feature for the reason that the hot Water usually enters the upper portion of the radiator and is gradually cooled as it flows downwardly. and in extremely cold weather the radiator may be maintained at a substantially uniform temperature by shielding the lower portion of the radiator.

The invention also includes certain details of construction forming" part of an adjustable curtain structure. the preferred form of which comprises a curtain wound around a roller and securely held so that the roller may be shifted to unwind the curtain. A flexible strand serving as a support for the roller is wound around the roller inia direction opposite to the winding of the curtain,

and when the roller is rotated to unwind the curtain. the flexible strand is wound onto the roller.

Figure 1 1s a trout elevation ot aniautomobile radiator. showing my shield applied,

thereto. F ll is an enlarged side elevation of the radiator, partly broken away,

some of the parts being shown in section.

Fig. ill is a detail view showing the parts at the middle portion of the roller.

In the accompanying drawings: A designates an automobile hood and B is a radiator provided with a filling nozzle C. A shield D comprises 'two curtain sections .1 wound around a roller 2, the lower ends of Said curtain sections being secured to a an transverse bar 3. 4 designates flexible clips for securing the. lower ends of the curtain sections to the lower portion of the radiator. These clips straddle the bar 3 and extend.

through the radiator, the inner ends of said ee clips being bent as seen in Fig. H.

A flexible strand 5 is secured to the roller at 6 and wound around said roller in a direction opposite to the winding of the curtain ably a wire secured between the curtain-sec- "tions and having its upper end secured to sections. This flexible strand 5 is preferto ably a rubber loop provided with a fabric 3o covering.

The curtain sections and the flexible strand 5 are held under tension by the clastic member 7, therefore the shield is firmly held against the face of the radiator and 3d the roller may be rotated with the result of winding up the flexible strand. and unwinding the curtain sections. lVhcn the roller is so rotated it is shifted to different elevations above the bottom of the radiator and 35 it is supported at all times by the flexible strand 5. r v

The roller tends to drop by gravity, however, the parts are so arranged that the roller will remainin its adjusted position until it is turned by the operator. A downward movement of the roller is resisted by the flexible strand 5 which is preferably a wire arranged to unwind from the roller when tb latter moves downwardly. It will be noted that the roller cannot drop without bending the wire strand 5, at the same time winding the curtain onto the roller, and the energy required to eilect these winding and unwinding operations is greater than the force of gravity tending to move the roller downwardly. Therefore the roller is retained in its adjusted position without the use of fastening devices such as have been heretofore employed to support curtainsand curtain rollers. 1

If desired, the upper end of the curtain and the roller may be supported by pegs or arms 8 secured to the radiator, see Fig. 11.

I claim:

1. in a device of the character described,

i the roller and saidupport and tho-opposite end of each curtain section begins? wound around the roller, and a wire having one end secured to wound thereabout inn direction opposed to that in which the'curtain is Wound, the other end of the wire being'secured to the support at a point opposite the attachment of the curtain.

In a device of the character described, a support, h roller, :1 iouble curtain comprising a pair of curt in sections, one end of each curtain section being attached to said support and the opposite-end of each curtaln section being Wound around the roller,

and a'wire having one end secured to the middle portion of'the roller at a point between the curtain sections and wound around the roller in a direction opposed to that in which the curtain is wound, the other endof to that in which the and the opposite end hr" each curtain section being Wound around the roller, a Wire having one end secured to the roller and wound thereabout in a direction opposed curtain is Wound, and an elastic compensating member connecting the other end of said wire to said support at a point opposite the attachment of the curtain so as to place the curtain and'wire under tension.
