Application September 7, 1954, Serial No. 454,435

Claims. (Cl. 220-234) This invention'relate's to a hinge means and more particularly to a hinge for canopy lids wherein the lid must move upwardly to clear the container to which it is attached, prior to its full hinge swinging action.

Heretofore canopy lids on containers either have no hinge connection or must rely on two pairs of arm bars angularly spaced apart to permit additional upward movement of the lid relative to the container. In the first instance there is no way to hold the lid onto the container against accidental detachment. Also in many cases the user wishes to lock the lid onto the container. In the latter method, at least four hinge bars are required and they are costly in both material, labor and installation. Furthermore, the two bars that make up each pair of bars are not fastened together and, therefore, the lid when raised is very unstable. This often results in the twisting and distorting of both lid and the bar hinges.

Therefore, one of the principal objects of my invention is toprovide a one-piece hinge for canopy lids that is easily and'quickly installed.

A further object of my invention is to provide a canopy lid hinge that braces and strengthens the lid against distortion when in a non-closed condition.

Still further objects of this invention are to provide a canopy lid hinge means that is economical in manufacture, durable in use, and refined in appearance.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangements, and combination, of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in my claims, and illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of my hinge means on a lid canopy and its container,

Fig. 2 is an end view of my device with sections cut away to more fully illustrate its construction, and

Fig. 3 is a vertical sectional view of my hinge means on a container and canopy lid taken on line 3-3 of Fig. 2.

While my lid hinge may be used for various purposes, I find it is excellent to securing canopy lids on animal food containers. In the drawing I have used the numeral 10 to designate. the...rectangular top portion of a hog feeder or like. Thenumeral 11 generally designates the canopy top. Such tops have a lower vertical rim area 12 which telescopes around the upper rim portion of the container 10. Usually such lids have a sloping roof and ends 13 and 14. It is to such or similar structure that I apply my invention and which I will now describe in detail. My hinge consists (besides the fastening means) of one piece. I secure one hinge at each end of the lid as shown in Fig. 3. The hinge is generally designated by the numeral 15. It may be of any suitable shape provided it has a leg portion, and substantially a horizontal portion. The chief idea being the location of the points it is secured to the lid and container and the relation of 2,791,348 Patented May 7, 1957 f 2 such points to each othe'r. Therefore, I have madethe part 15 and substantially L-shaped such as I show in the drawing. The downwardly extendingportion 16', or leg, has its lower end portion pivoted to the rear top portion of the container by any suitable detachable means such as a headed pin and cotter key unit 17, loosely extending through the portion 16 and the end wall of the container as shown in Fig. 3. The numeral 18 designates the horizontal area of the member 15. The numeral 19 designates a headed pin or rivet and cotter key unit 19 loosely detachably extending through the area' 18 and the end lower edge portion of the lid. The point of this pivot unit 19 is above and forwardly of the pivot unit 17 as shown in Fig. 2. The upper area portion of the unit 15 extends between the end of the container and the side of the lid. Both

pivot points

17 and 19 are in the vicinity of the rear vertical plane of the container but the pivot point 17 is the closer of the two. 7

Horizontally forward of the pivot point 19 and substantially spaced therefrom is the slot 20 formed in the unit 15. This slot is arcuate and has a radius in the pivot point 19. Loosely extending through this slot 20 and the vertical lower end of the lid is a headed pin and cotter key unit 21. This point 21 is not a pivot point, but permits relative limited sliding action between'the forward end of the member 15 and the front end portion of the canopy lid. Inasmuch as the slot 20 is on a radius concentric with the pin 19, the lid will have limited hinge action on the pin 19. By this arrangement, if the lidis manually raised, its first movement will be that of its front side raising upwardly so that. its front rim 12 will clear the front wall of the container.' This initial move ment is illustrated by the broken lines in Fig. 2 and is the result of the headed pin 21 sliding in the slot 20, prior to any movement of the member 15. After the pin 21 has reached its maximum sliding movement in the slot 20, and the front of the lid is clear of the front of the container 10 any further movement of the lid will be to hinge on the pin 17. Prior to this the lid is hinged on the pin 19. The lid can then be swung back to its extreme. open position, also shown by broken lines in Fig. 2. One of my hinges is installed at each end of the container 10. In closing the lid the parts operate in reverse, i. e., the lid first hingeson the headed pins 17 and lastly on the headed pinsv 21. This permits the front of the lid to pass over and then snugly adjacent the front wall of the container. By the entire area 18 of each member 15 being held closely adjacent the inner end sides of the lid, respectively, the lid when in open condition will be braced by the members, against distortion or twisting actions. This is made possible by the distance between the

pins

19 and 21, which is a substantial end area of the lid. Also the lid will open and close more easily as the members 15 are flat and L-shaped and the lid will thus be always properly held in alignment with the container.

Some changes may be made in the construction and arrangement of my canopy lid hinge without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
