claims. (01. 98-410) ent'io'n is more sp cifically concerned with a iitv' and novel form jbf pivots used, in
c njiin'ction w'ithth'e adjustab e deflector blades, and "cdobiatm'g partswmcnnave been so com- Breed and assembled to form a very simplified and economical construction.
Another object of this invention is to provide an adjustable deflector blade which is easily rotated from one position to another without the use of tools or unnecessary effort and which blade remains firmly in any position of adjustment without looseness that might cause rattling or change of position of the blade.
The deflector blades being readily adjustable, they are capable of adjustment to direct the air stream to the most eflicient deflected direction.
Another object of this invention is to provide an adjustable deflector readily manufactured by using'modern methods and tools in a fast mass production manner.
Other'objects and advantages will appear in the course of this specification, and with said objects and advantages in view, this invention consists in the several novel features hereinafter fully .set forth and more particularly defined in the appended claims,
The invention is clearly illustrated in the drawing accompanying this specification in which:
Fig. 1 is a front elevation of an adjustable deflector embodying a simple form of the present invention.
Fig; 2 is an end elevation thereof, partly broken out to illustrate parts within, and
Fig. 3 is a view similar to Fig. 2 showing a slight modification,
Referring to said drawing, and first to Figs. 1 and 2, the reference character 5 designates an air outlet frame here shown as composed of angle shaped pieces 6, I with their corners mitered and suitably secured together. The frame may be secured on the air discharge end of aconduit. The horizontal flanges 8, 9 of thefpie'ces 6, are provided with oppositely disposed bearing apertures at [0, l I in which are rotatably mounted trunnions l2, l3 that are slotted and Welded or otherwise rigidly secured to the opposite ends of the deflector blades I 4. The deflector blades are preferably of rectangular form and any desirable number of blades may be used in connection with the frame; when the blades are aligned as shown in Fig. 1, they practically close the outlet opening I5 of the frame.
2 The'trunnions l -2 are cylindrical, fitting fairly wen in the bearing apertures I 0. The trunnions i3 'aretapered with their larger ends secured to the blades. The tapered trunnions seat on the edges of the bearing apertures II, which apertures are of such diameter that the tapered trunnions seat on the edges of the apertures at approximately midway of their lengths.
Me'a'ns are provided for urging the tapered trunnions upon their seats so as to obtain more or less friction between the tapered trunnions and their seats, whereby to hold the deflector blades in any position of adjustment but permitting them to be adjustably rotated to any desired position without any great effort.
The means shown in Figs. 1 and 2 for creating the friction between the tapered trunnions and their seats comprise a flat spring I6 which lies on the upper ends of the cylindrical trunnions and is pressed against said trunnions by screws H, which extend through the flange 8 of 'the frame and are threaded in the spring. By tightening up the screws more or less pressure is applied by the spring to the cylindrical trunnions and as a result the tapered trunnions are forced more or less tightly upon their seats around the apertures ll, thereby causing sufficient friction to prevent free-rotation of the blades.
In the modified form of tension means illustrated in Fig. 3, the cylindrical trunnion is formed with a slotted head l8 secured to the blade Ma and a coil compression spring I9 is interposed between the head I 8 and flange 8 of the frame. The lower tapered trunnion l3a may be constructed similarly to the trunnion [3. A coiled spring of sufiicient strength should be used that will force the tapered trunnion tightly upon its seat.
Both the cylindrical and tapered trunnions may be formed from separate pieces of material and suitably attached to the blades by welding or otherwise, or if the trunnions are made of sheet metal they may be formed directly from the stock of blades and bent into cylindrical or tapered form.
Having thus described my invention, it will be apparent that various immaterial modifications may be made therein without departing from the spirit or scope of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.
What I claim as new and desire to secure by Letters Patent is:
1. A deflector comprising a flanged outlet frame, having oppositely disposed bearing apertures therein, one or more pivotally adjustable deflector blades each having a headed cylindrical trunnion secured thereto at one end, and a tapered trunnion secured thereto at the other end, both trunnions being rotatably mounted in the bearing apertures in flanges of the frame and coiled compression springs bearing against the heads of the cylindrical trunnions and flange for urging the tapered trunnions into wedging engagement with their bearing apertures to provide a friction lock, normally firmly retaining the respective deflectors in their adjusted position, but permitting manual individual adjustment thereof.
2. A deflector comprising an outlet frame, having oppositely disposed bearing apertures therein, one or more deflector blades each having a cylindrical trunnion at one end, and a tapered trunnion at the other end, both trunnions being rotatably mounted in the bearing apertures in the frame, a spring bearing against the ends of the cylindrical trunnion for urging the tapered trunnions upon their seats, and adjustment means acting on said spring for varying the amount of pressure on the cylindrical trunnions.
3. A deflector comprising on outlet frame, having oppositely disposed bearing apertures therein, one or more deflector blades each having a cylindrical trunnion at one end, and a tapered trunnion at the other end, both trunnions being rotatably mounted in the bearing apertures in the frame, a flat spring bearing against the end of the cylindrical trunnions for urging the tapered trunnions upon their seats, and adjustment screws carried by the frame and threaded in the spring acting on said spring for varying the amount of pressure on the cylindrical trunnions.
