RADIATOR SHUTTER.

, Application. filed October 14, 1925. Serialv No. 62,427.

This invention relates to a'shutter for use in connection with radiators which are emplo ed on automobiles for the purpose of coo ing the water which is circulated around the engine, the purpose of this shutter belng to control the flow of air through the radiator in accordance with the temperature simple and inexpensive in construction,

which can be readily applied to radiators of standard construction, and vhich can be readily adjusted for controlling the amount of air passing through the radiator to suit the temperature of the weather and which is not liable to get out of order even when subjected to comparatively rough usage. a

The mainframe of the shutter may be of any suitable form to suit the shape 01' the radiator with'which the same is associated. In the present case this shutter frame is constructed from asingle sheet of metal which is stamped so that it is of sub vstantially rectangular form and comprises upper and lower horizontal cross plates. 1011 and vertical side plates 1212 connecting the corresponding ends of the upper and lower plates 10-11.

The inner edge portion of the top, bottom and side plates of this frame are dished or bulged forwardly so as to form an inner rim all around this edge of the frame. The inner edges of the vertical portions 13 of this rim are provided with inwardly and rearwardly projecting vertical flanges 14,

the inner edge of the upper horizontal portion 15 of this rim isprovided with an inwardly and rearwardly projecting horizontal flange 16 and the lower horizontal portion 17 of this rim is provided at its inner edge with a horizontal and rearwardly projecting flange 18, said flanges, rim and frame plates being all constructed integrally from a single sheet of metal.

Arranged across the opening Within the "frame between the flanges 14, 16 and 18 thereof is a plurality of slats or louvers 9 which are pivotally mounted on the frame so that they can be either fully closed or fully opened or arranged in an intermediate or partly open position and thereby enable the air supply to the radiator to be controlled in accordance with the temperature of the atmosphere in which the radiator is to be used.- These slats may be variously arranged, but in the construction shown in Figures 1 to 12 each slat is arranged vertically and the several slats arearranged in a horizontal row transverselyacross the space within the shutter frame. In the preferred construction each of these slats is constructed from a single sheet of metal which is pivotally mounted at its opposite ends on the shutter frame and in the closed position of the several slats each intermediate slat laps at its opposite vertical edges over the corresponding edges of adjacent slats and the outer vertical edges of the extreme slats either enga c with or are arranged close to the a jacent inner edge flanges of the frame. In order to produce a practically air tight joint between the several slats when they are thus closed each slat is provided on one of its vertical edges with a vertical groove 19 which is adapted to receive a flange 20 on the opposing vertical edge of an adjacent slat when the several slats are in their closed position, as shown in Figures 2 and 3, thereby excluding the air from the radiator when the shutter is in its fully closed position.

In the preferred construction the seal ng groove 19 on each slat is on the rear side thereof and the sealing flange 20 is on the front side thereof whereby any abrasion or marking of these slats when they engage with each other in their fully closed position will not be visible from the front side 5 of the shutter and thereby always maintain the same constantly in a neat and finished appearance.

For the purpose of stiffening these shutter slats each slat is provided midway between its vertical edges with a forwardly projecting vertical head 21 which is preferably of I semi-cylindrical form. The pivots or trunnions 22, 23 whereby each slat is pivotally mounted at its upper and lower ends on the shutter frame are preferably formed intogrally of the same sheet of metal from which the slat itself is made. This is accomplished by providing the upper and lower ends of each slat with an extension which is bent into tubular form and preferably concentric with the semi-cylindrical head 21 so as to practically form a continuation thereof, as shown in Figures l, 5 and 9 to 12, the joint 2 .1. in each of these pivots or trunnions being preferably arranged centrally on the rear side of each pivot.

These pivots or trunnions of the several slats are journaled in bearing openings 25, 26 formed in the upper and lower bearing flanges 1G and 18 of the shutter frame, as best shown in Figures 9 to 10. The hear ing openings in one of these bearing flanges, for example the bearing openings 25 in the upper flange 16 are complete and unbroken and each of these bearing openings there fore provides a continuous or uninterrupted cylindrical bearing surface in which the respective pivot pin or trunnion 22 turns. The bearing openings in the other bearing flange, in this instance the bearing openings 26 of the flange 18, are each connected with the adjacent edge of the respective flange by means of a slit 27 extending from this open ing to said edge of this hearing flange, as shown in Figure 4, whereby one side of each of these bearing openings 26 may be opened up sufficiently to form an entrance way or throat 29 through which the respective lower pivot pin or trunnion 23 may be moved sidewise into this hearing opening and thereafter this entrance way or throat may be again closed for the purpose of confining the pivot pin or trunnion of the shutter slat therein. As shown in Figure 4 the slit 27 extends tangentially from the pivot opening 16 to the rear edge of the bearing flange 18, thereby forming a retain- 111g lip 28 in rear of the pivot pin 28 which confines the latter in the respective bearing opening. Upon however bending this ii) 28 downwardly, as shown in Figures 6 anil 7 a wide passageway or throat 29 is formed extending from the respective bearing openmg 28 to the rear edge of the bearing flange, thereby permitting the lower pivot pin or trunnion on one of the slats to be passed laterally through the throat 29 and then the retaining lip 28 is again bent back into its normal position flush with the remaining port ons of the bearing flange 1.8, as shown in Figure 5 whereby the pivot pin 23 is prevented from moving out from the pivot opening 26. By means of this construction each of the slats may therefore be quickly assembled with the frame by first passing its upper pin or trunnion 22 lengthwise through one of the openings 25 of the upper bearing flange from the under side thereof and then moving the lower pivot pin or trunnion 23 laterally into engagement with one of the lower pivot openings 26, a d then taining these parts in this position by bondmg the lip 28 into a position across the throat 29. The pivotal mountin of each slat on the frame is therefore e 'ected by these means without the employment of any separate pieces which are deta'chably connected with the frame and without the use of any solder, riveting or sin'iilar fastening,

thereby not only simplifying the construc tion and ermitting of manufacturing the shutter at ow cost but also avoiding the persibility of any of the parts becomin loose or detached when the shutter is subjected to vibrations or rattling incident to the use of such a shutter on the radiator of an auto mobile.

Various means may be provided for cans ing the shutter blades or ate to turn in unison for opening and closing the same either wholly or partly. 'lhe preferred means for this purpose are constructed as follows:

The numeral 30 represents an operating arm or cranlr which projects rearwardly from each slat and is preferably formed integrally therewith at the upper end there of from a single sheet of metal, as shown in Figure 8. Theseveral o erating arms of the group of slats or bla es are connected lil'ti web 31 arranged in rear of the rear ends of the several operating arms and provided with upper and lower walls or flan es 32, 33 which are arranged respectively a ove and below the several operating arms of the group of shutter slats. Although various means may be provided for ivotally connecting this shifting bar wit the several operating arms it is preferable to accomplish the pivotal connection between each arm and.

the shifting bar by providing one of; the flanges of the shifting bar, for instance the upper flange with downwardly projecting teats or projections 34 each of which engages with a recess 35 in the adjacent part of the upper side of one of the operating arms 30 while the lower flange or wall of the shifting tofore known and used, the same are as- 7 bar is provided with a plurality of upwardly projecting teats or projections 36 each of which bears against the even or undented under side of one of the operating arms 30, as shown in Figure 8.

By this means a pivotal connection is produced between the operating arm of each shutter slat and 'the shifting bar which avoids the use of any bolts, pins, rivets or other separate pivoting member which not only simplifies and reduces the costof manufacture but also avoids the liabilit of such separate parts becoming loose. oreover the present'pivotal connection between the shifting bar and the arms of the shutter slats operates with a minimum of friction so that the wear upon the same is unappreciable and therefore maintains the shutter indefinitely in good working condition.

This shifting bar may be moved horizontally in one direction or the other crosswise of the shutter by any suitable means and from any suitable place on the automobile or elsewhere and as such means do not form any feature of this invention no disclosure or description of the same is deemed neces: sary.

Instead of arranging the shutter slats or blades vertically and in a horizontal row across the space within the shutter frame, as

shown in Fi res 1, 2 and 3 the same result is accomplis ed by arranging the shutter slats or blades in a horizontal position and in afvertical row in the space across the frame, as shown in Figure 13, and since this changed arrangement in no wise alters the construction of the shutter as a whole the same reference characters which are used with reference to the structure shown in Figures 1 to 12 are also employed in the construction shown in Figure 13, it being assumed that the bearing flange at the lefthand side of Figure 13 corresponds to the upper bearing flange of the construction shown in Figure 1 and the bearing flange at the right-hand side of Figure 13 corre-- sponds to the lower bearing flange 18 in Figure 1.

As a whole this radiator shutter is com- ,posed of much fewer parts than those heresembled without the use of any bolts, rivets or other separate fastenings and also without employing any soldering, brazing or the like and the several parts are also so mounted relatively to each other that they work with a minimum amount of friction, thereby enabling this shutter to be manufactured at low cost and to be operated with ease and convenience and without liability of getting out of order.

I claim as my invention A radiator shutter comprising a sheet metal frame provided with hearing flanges, a plurality of slats arran ed in a row across the space Within said rame and having pintles journaled in said flanges and each slat being provided with an integral arm and each arm being flat on one side and provided with a recess on its opposite side, and a shifting bar of channel form having its walls arranged on opposite sides of said arms and one of said walls being provided with a plurality of pivot teats each of which engages with the recess in one of said arms and the other wall'of said bar being provided with a plurality of teats each of which engages with the opposite flat side of one of said arms.

In testimony whereof I afiix my signature.
