Application led August 23, v1152.0, Serial No. 405,372.

' To all .fw/7mm t may conceive.

Be it known that I, ROBERT L. PATn, moitizen of the United States, ifesiding fait the eit7 of Springfield, eonnty of Greene, fnd State .of Bitiseouri, lione invented a new and useful Radiator Contain lor Cover, 'of which the following yis e speeieation.

This invention relates to radiator A.enr-,tenne' or warying temperatures.

An opening 7 is left between the lower edges of the wall 6 and the wall 5 to permit free movement of the curtain as the curtain is wound or unwound from the roll. The roller is supported for rotation b y the end walls of the housing. As shown in Fig. 2, the lower part of the wall 5 is provided with an up-turned portion 8 spaced from the main portion of the wall 5 so as to extend between the radiator core and the engaged portion of the radiator shell. As shown, the engaged portion of the radiator shell is received between the main portion of the wall 5 and the turned portion 8 thereof and fasteners 9, properly positioned and secured, hold the parts rigidly in proper position. The curtain 3 extends entirely across the radiator opening and is retained and guided in its movements by guides 10.

As shown the guides 10 are angular metallic strips having their outer edges extending between the radiator core and the vertical parts of the radiator shell and their inner edges spaced from the radiator shell to extend in front of the side edges of the curtain and thereby retain the curtain close to the radiator core and guide the curtain properly in its movements. The guides 10 serve to prevent passage of air around the side edges of the curtain through the radiator core. The upper ends of the guides 10 may be in connection with the wall 5 of the roll housing and the lower ends of said guides may be held in place by a transverse bar or strip 11. If desired, the strip 11 may be used as a support for the license plate or other emblem and for such purpose may be provided with openings 12 for the reception of the fastening elements. The lower end of the flexible curtain is reinforced by a metal strip 13, and the ends of the strip extend behind the guides 10 so that it is impossible for the end of the curtain to fold or to become disconnected from the guides.

The operating device shown includes two flexible connections 14 which may be in the form of cords or wires connected to the reinforcing strip 13 by an appropriate connection 15, passing around a roller 16 supported 3y the radiator at the side opposite from that at which the roll 4 is supported. The connections 14 pass over the radiator on opposite sides of the radiator cap, whereby they are held in proper position. The connections 14 are united at a point 17 sufficiently to the rear of the radiator cap to permit the curtain to wind entirely on the roll 4. The arrangement is such that when the connecting portion 17 of the connections 14 engage the radiator cap the curtain is wound entirely on the roll 4. This construction prevents the roll 4 from operating too far and serves to stop operation of said roll at the proper time when the curtain is wound entirely on the roll, leaving the radiator entirely uncovered. A' connection 18 extends from the union of the connections 14 to a connection with a combined operating and gauge device 19. The device 19 extends over the dash of the vehicle and on one side thereof is provided with a temperature gauge shown in Fig. 5, indicating dierent degrees of temperature and constituting a guide whereby the driver is informed of the proper adjustment of the curtain in weather of different degrees of temperature.

The device 19 is formed with a row of eyelets 20 for engagement with a hook 21 supported by the dash of the vehicle. By this arrangement the operating connection may be secured and held in position to retain the curtain in any adjustment in which it may be placed. The opposite side of the device 19 is formed with a scale, shown in Fig. 6, to indicate to the driver the extent to which the curtain is opened or closed, so that the operator has optional means for his guidance in adjusting the curtain.

The construction shown in Figs. 4 and 7 is built in as a part of the radiator shell, as distinguished from the accessory form of the device shown in the other views of the drawing. In the form shown in Figs. 4 and 7, the housing for the roll comprises a wall 22 which may be provided by shaping properly the upper portion of the radiator shell. As shown7 t-he wall 22 extends obliquely downwardly and forwardly from the upper edge of the radiator shell and curved under the roll and has its lower edge spaced from the radiator to leave an opening for the movement of the curtain, similar to the opening 7 previously described. The remaining parts of the device disclosed in Figs. 4 and 7, including the operating means may be of the same construction and modey of operation as above described and therefore do not require repetition.

From the foregoing it will be seen that my invention completely serves all of its intended purposes. The device is of a simple and durable construction and when used as an accessory in connection with a previously constructed radiator it may be easily applied without removing or defacing any of the existing parts of the radiator. When properly constructed and applied the device con I stitutes an ornamental feature in connection. with the radiator and is also of high elficiency and utility. When embodied as a part of the radiator during construction of the radiator, the device may be made without departing widely from the present radiator construction. Indeed, when constructed as a part of the radiator the special guide plates 10 may be omitted. The necessary guides may be provided in such case by shaping the inner edges of the vertical members of the radiator ,shell to provide guiding portions 23 spaced from the radiator core to engage in front of the side edges of the curtain. This construction will be readily understood by reference to Fig. 7, in which the guides 23 are shown as integral parts of the vertical members of the radiator shell.

It is obvious that there may be variations in the construction and arrangement of the device without departing from the nature and principle of the invention.

I do not restrict myself to unessential features or limitations in any particular, but what I claim and desire to secure by Letters Patent, is

l. The combination with a radiator of an automobile, and a radiator shell, of a supporting enclosure at the top of the radiator having its upper edge forming an imperforate connection with the radiator shell and leaving a space between its lower edge and the radiator, a roller supported for rotation in said enclosure, a curtain having one end attached to the roller and being movable upwardly and downwardly at the front of the radiator through said space to increase or reduce the exposed working area of the radiator, means in connection with the radiator for engaging the side edges of the curtain passing through said space to guide the curtain and to hold the curtain close to the radiator, and a reinforcing strip in connection with the lower edge of the curtain extending across in front of the radiator and holding the curtain properly spread across close tothe front of the radiator and with its edges engaging said means.

2. The combination with a radiator of an automobile, of a supporting and enclosing housing attached to the radiator at the top of the radiator and having a space at the lower side thereof adjacent to the radiator, a roller supported at the top of the radiator within said housing, a curtain having one end attached to said roller and being movable upwardly and downwardly at the front of the radiator through said space while the roller remains within the housing, elements in connection with the vertical sides of the radiator for engaging the side edges of the curtain extending through said space to hold the curtain in proper position against the radiator and in proper position for movement through said space, a member means.
