VENTILATING SHUTTERS.

Application filed JanuarylB, 1928. Serial No. 247,960.

The present invent-ion relates to ventilating shutters such as used on the radiators of the water cooling systems for automobile and airplane cng'ines, and the like, and aims to provide novel means for connecting the shutters to control the opening movements thereof, this invention being an improvement on the ventilating shutters disclosed in my pending application Serial No. 187,959, filed April 1927. With the present improvements it is pos sible with a vertical series of shutters to open them in succession beginning with the upper shutter, which is especially advantageous for use in automobile and airship radiators, it being well'known that the radiators will be come hottest at the top and are most likely to freeze at the lower portions thereof. Therefore, by opening'the shutters from the top downward in succession the air is first. admitted through the upper portion. 01 the radiator, where the cooling effect is most needed, and by opening the shutters further air is gradually admitted at lower points although in less amounts than higher up, the upper shutters opening. further as the lower shutters are opened in succession so that the maxi mum flow of air is through the upper portion of the radiator, and only after the upper shut- 9 ters are opened will the lower shutters be opened. l

Vi ith the foregoing and other objects-in view which will be a arent as the descri a- .tion proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a vertical section of a ventilating shutter c onstruction embodying the improvements, taken on the line 1-1 of Fig. 2. A lg. 2 is a fragmentary rear view of the device, portions being broken away. I

Fig. 3 is a'horizontal section on the line 3-3 ot Fig. 1, portions being broken away. l ig. Al is a fragmentary section illustrating a modification.

The shutters 7 shown in- Figs. 1, 2 and 3 are of suitable sheet metal and are arranged in a vertical series, being disposed horizontally. The shutters arehingedly mounted to swing open rearwardly and upwardly, the

upper edges of said shutters belng bent around, as at 8, horizontal hinge rods 9 which have projecting terminals mounted for rotation in suitable vertical bearing bars 10. The shutters are arrangedwithin or behind an opening 11 in a shell 12, which may be the radiator shell or a shell applied in front of the radiator,'as well known. The lower portions of the shutters 7 are bent or oii set rearwardly downwardly and forWardly,-as at 13, to provide grooved portions to snugly receive the beads 8 of the shutters immediately below, when the shutters are closed, as seen at the lower portion of Fig. 1, so as to provide substantially airtight contact of the shutters in closedposition. The lower edge portions of the shutters thereby extend partly under the beads 8 of the shutters imn'iediately below, when the shutters are closed, and the lower or free edges ofthe shutters are bent, as at 14, around rods which stiffen and reinforce the shutters. The beads 14 and rods 15 are thus adapted to move partly below the corresponding beads 8 and rods 9, when the shutters are closed, thereby providinn amore compact arrangement. I v

rflach shutter has a yokelG welded or otherwise secured to theridge formed by the grooved portion or offset 13 above the bead 14c, and, said yokes extend rearwardly and have horizontal hinge portions or rods 17 parallel with and above the corresponding rods 15. V

The shutters are connected by links 18 which have their upper ends embracing the hinge rods 15 within openings formed by the interruptions oi the beads 14, as seen in Fi 2, and thelower ends of the rods engage the hinge portions 17 of the yokes of theshutters immediately below. v

A link or bar 19 is connected to the yoke 16 of the uppermost shutter and may beamtrolled by a thermostat or by a handieor other suitable means for opening and closing the shutters, the shutters operating the same for either automatic or manual'control.

The arrangement of the yokes 16 and links 18 is such that when the shutters are closed, as seen at the lower portion of Fig. 1, each link 18 which extends downwardly from the corresponding shutter'is substantially on a line with the hinge rod or axis 9 of said shutter, as indicated at 20. Thus, the shutter and link extending downwardly therefrom maybe said to be in substantially dead center or looking position, with the shutter and link straightened out with reference to the toggle-action thereof. Now, when the bar or ter, the uppermost shutter is swung upwardly by said bar 19, and the uppermost or first shutter in swinging rearwardly will swing the upper end of the first link rearwardly, thereby breaking the toggle formed by the first shutter and first link. The first link is pulled upwardly with the first shutter. This will start the second shutter rearwardly and upwardly, and after it starts to swing rearwardly it pulls the second link upwardly which in turn then starts the third shutter in its opening movement. WVith this arrangement it is necessary that each shutter open rearwardly slightly before the link extending downwardly therefrom is raised to start the rearward movement 01? the next lower shutter, and consequently the shutters open in succession from the HDDQNHOSt shutter downwardly as seen in Fig. 1. This will open the shutters from the top downward so that the air is first admitted through the upper portion of the shutter and is gradually admitted at points lower down as the opening movement of the shutters is continued. The shutters not only open in succession from the uppermost shutter downwardly, but also swing open through greater angles or to greater extents from the u ipermost shutter downwardly, so that larger streams of air are admitted through the upper portion of the shutter than through portions lower down. Then the bar 19 is moved downwardly to close the shutters the shutters close in succession from the lowermost shutter upwardly, just reverse to the opening movements of said shutters.

4; illustrates the lower edge portion 13 ot' the shutter 7 bent to extend under the head 8 and rod 9', and the upper end of the link 18 is connected to the hinge portion or rod 15' of a yoke 14: secured to the portion 13 similar to the yoke 16 having the rod or hinge portion 17. Thus, the head 14; and rod 15 hereinbefore described are omitted and are substituted by the yoke l l corresponding with the yoke 16. Both ends of the links are therefore connected with the yokes which are welded or otherwise secured to the grooved portions 13 01 the shutters.

Having thus described the invention, what is claimed as new is 1. A series of shutters each having a beaded hinge portion and an offset portion to tit partly around the beaded hinge portion of the companion shutter, and links between the shutters er eh having one end h'ingedly connected with the ofiset portion of one shutter and having its other end hingedly connected with the companion shutter oeyond said oil"- set portion thereof. 1

2. A vertical series of shutters each having a beaded hinge portion and an offset portion lower down to tit partly around the beaded hingeportion of the next lower shutter, and links between the shutters each having one end hingedly connected with one shutter be low said oflset portion thereof and having its other end hingedly connected with the next lower shutter.

3. A vertical series of shutters each having a beaded hinge portion and an offset portion lower down to tit partly around the beaded hinge portion ofthe next lower shutter, and links Jetween the shutters having one end hingedly connected with one shutter below the oiiset portion thereof to move under the beaued hinge portion of the next lower shutter, the other end of each link being hingedly connected with the ofiset portion 01% said next lower shutter.

In testimony whereof I hereunto ailix my signature.
