Application fiiea June 15,41925. serial Na. 37,290.

This invention relates to radiator fronts particularly those having shutters therein which may be controlled from the automobile seat. The inveiitio'n is fully described in the following specific-ation and shown iii in the accompanying drawings, in which- `Figure 1 is a Vertical section through an automobile radiator sliowing a front embodying the invention,

Fig. 2 is a liorizontal section through the same on the line 2-2 of F ig. 1,

Fig. 3 is a side elevation of the radiator and front showing the control tlierefor,

F ifl'. 4 is an enlarged partial section on the line 4-4 of Fig. 3,

F ig. 5 is a Vertical section through the front on' the line 5 of Fig. 2,

Fig. G'is a rear view of' the same,

Fig. 7 is a front view 'of the radiator front, and

F igs. 8 and 9 are enlarged' prospective views of the ends of the sliutters.

The embodiment illustrated comprises a radiator of awell-known type having upper and lower reservoirs 10 and 11 respectively connected by means of Vertical tubes 12 and having a series of horizontal fins 13.

My radiator front which is adapted to be secured to this radiator has a frame coinprising a web 14 and a flange 15, the latter being bolted to the front of the radiator by means of bolts 16 which pass through openings 17 in the radiator front and through the spaces between the fins 13. and the pipes 12.. V

Across the middle of the radiator front is disposed a series of sliutter blades or vanes 18, 19 and 20, as shown in Fig. Each vane has a central disposed pin 21 at one Vend and a crank 22 at the other, these piiis and cranks being journalled in Vertical side members 23 which are carried by the members 14. o The vanes 18. are preferably formed from sheet metal and are secured to the flattened ends of the pins 21 and cranks 22 as by spot Welding. The meeting edges of the ad]a cent vanes overlap as is shown in Fig. 5, these edges being preferably curved -as there shown for this purpose.

The cranks 22 of the upper set of vanes 18 are all of the same length and are set at the same angle with respect to the vanes 18, the crank arms of each of these cranks passing through a movable member 24 which is normally pulled upward into closed position as shown in F igs. 5 and 6 by means of a tension spring 25, the vanes serving as `stops for each other when. closed.

-mounted and a pin' 29 as shown in Fig. 4.

A spring 30 forces this lever toward the plate 31 to which it is mounted, this plate being secured to the steering coluinu v32 by means of a band 33 and a bolt 34. This plate has a series of holes 35 thereiii which are adapted to be entered by the tongue 36 which is carried by thelever 28.

As the operator draws the lever 28 back it. acts through the Wire 27 and the operating lever 20 to rotate the upper vane about its piv'ots and' at the same tiine the movable men'ibei- 2-l which coimects all of the cranks 22 of the upper set of vanes 18, causes all of lthese vanes to simultaneously turn' toward opening position. The several open- -ings 35v iii the plate 31 correspond to'varying ilegress of opening ofthese upper vanes.

The next set of vanes 19 are similarly mounted, the cranks 22 however, being shorter than the cranks 22 of the upper set of vanes 18. The cranks, 22a likewise are all set at the same angle and are connected to a single movable member 24* which is in line with the movable meiiiber 24 and separated therefrom by sucli an interval that as the, member 24 is moved down with the opening of t'he vupper set of vanes 18, it will 'contact the meinber 24a only after the vanes 18 have been moved through an angle of about' 30. Any further lopening movement therefore of the vanes 18 Will cause the member 24 to depress the member 24a thereby causing the vanes 19 of the central group lto open simultaneously with a further opening ofthe upperwanes 18.

Similarly the vanes 20 of the lower group have cranks 22b which are shorter still than the cranks 22ai 'The cranks 22b are all connected by means of the inovable member 241' which lies below the member 24a and is Separated therefrom by the interval so that as the member 24a moves dowmvardly during the opening of the vanes 18 and 19, it

will strike the member 24h at a predetermincd point, after which all free members 24, 242* and 24h will move down together. Owing however to the fact that the cranks 22a are shorter than the cranks the vanes 19 will be given a greater angular movement for a given movement of the members 24 and 24:a and likewise since the cranlrs 22h are shorter than the cranks 22a, the vanes 20 will be opened even more rapidly. These parts are so proportioned that when the operating lever 26 has been moved to its full opening position which is substantially 90 from the position shown in full lines in Fig. 5 and when the tongue 36 will engage the last hole in the plate 31, all three sets of vanes 18, 19 and 20 will be substantially full opened.

Thus it will be seen that the vupper set of vanes 18 will be opened 'first while the vanes 19 and 20 remain closed thereby permitting the upper portion of the radiator to be cooledI by air passing through the open upper set of vanes. By a further movement of the lever 28 the upper set of vanes 18 is opened still further while the middle group 19 is partially opened. By further movement of this lever the lower group of vanes 20 is also opened 'lwhile those above are opened still further 'and a still further movement of this lever opens all groups to the full opened position.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable'of many modiications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims.

I claim:

1. In a radiator front, a series of vanes movable to substantially open or close said front to the passage ofair, said vanes being divided into groups, each vane having an operating` crank connected thereto, the cranks of each group -being of the same length, and. set at the same angle, a member operably connecting said cranks of each group, a spring tending to return each group of vanes to its closed position, said members being Separated by intervals and adapted to operatively cngage the succeeding members, so that the members of the iirst group when operated to open ters engage the members of the next group, forcing them to open as the first group continues to open, and so on with the next group until all groups are open.

2. In a radiator front, a series of vanes movable to substantially open or close said front to the passage of air, said vanes being divided into groups, each vane having an Operating crank connected thereto, the cranks of each group being Iof the same length, and set at the same angle, a member operably connecting said cranks of each group, a spring tending to return' each group of vanes to its closed position, said members being Separated by intervals and adapted to operatively engage the succeeding members, so that the members of the first group when operated to open the shutters engage the members of the next group, forcing them to open as the first group continues to open, and so on with the next group until all groups are open, the length of the cranks of each group successively decreasing.

GEORGE R. BARKER.
