a I Spec1ficat1on of Letters Patent.

Patented June 6, 1916.

Application filed October 23, 1915. Serial No. 57,559.

To all whom it may concern.

Be it known that I, STARKIE N. SLADE, a citizen of the United States, residing at Durham, in the county of Durham and State of North Carolina, have invented a new and useful Plant-Protector, of which the following is a specification.

The device forming the subject matter of this application is a plant protector embodying a tubular casing, and the invention. aims to provide novel means for detachably holding a closure on the end of the casing.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed,it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing :Figure 1 shows in plan, a plant protector constructed in accordance with the present invention;

Fig. 2 is a side elevation of the protector;

Fig. 3 is a sectional detail taken through the bottom of the protector; Fig. 4 is a plan of the blank out of which the protector is fashioned; Fig. 5 is an end elevation showing a slightly modified form of the invention.

The protector forming the subject matter of this application is made out of a blank 1 preferably of metal, the blank 1 having transverse edges 2 and 3 and longitudinal edges 4. In the edge 2 of the blank 1, inclined slits 5 are formed. Projecting from the edge 2 of the blank 1 are tongues 7 disposed at an acute angle to one of the longitudinal edges 4, so as to define points 8. In the opposite transverse edge 3 of the blank 1, notches 9 are fashioned, these notches in one blank being formed by the cutting out of the tongues 7 on an adjoining blank. The edges 4 of the blank 1 are brought together and united by a lock seam 10, thus to form a tubular casing as shown in Fig. 1 of the drawings. This casing may be of any desired cross sectional contour, but the casing may be flattened, as indicated at 11 or otherwise. The tongues 7 are bent over toward each other to form ears 12 and 14, the free edges of which are inclined, as shown at 17 and are in approximate parallelism. The material freed by the formation of the slits 5 is bent outwardly to form prongs 15, the functions of which will be alluded to hereinafter.

The invention comprises an approximately rectangular closure 16. This closure 16 may be made of glass, cardboard, netting or any other suitable substance. In mounting the closure 16 in place on the casing, the closure s first tilted into the inclined position shown in dotted lines in Fig. 1, the closure being passed between the approximately parallel edges 17 of the ears 12 and 14. Thereupon, the closure is permitted to gravitate into an approximately horizontal position, as clearly shown in solid lines in Fig. 1, under which clrcumstances the closure will be retained by the ears 12 and 14.

It is to be observed that the ear 12 lies closer to the vertical'median plane AB of the casing than does the ear 14. Consequently, the lower edge of the closure 16 is fulcrumed on the ear l2 and the upper edge of the closure is maintained in engagement with the ear 14, by the weight of the closure.

The closure need not be in the form of a plate, but may be in the form of a piece of netting or cloth, under which circumstances the closure is retained on the outwardly projecting prongs 15.

The closure 16 preferably is of such a width that the small air inlet opening 18 exists between the upper edge of the closure and the upper portion of the casing.

As shown in Fig. 5 of the drawings, the tubular casing is denoted by the numeral 100 and is provided at both ends with outwardly projecting triangular prongs 101, adapted like the prongs 15 to receive a closure of cloth, netting or the like. The triangular form given to the prongs makes the removal of the closure a matter easily accomplished.

The tubular casing shown in Fig. 1 of the drawings is adapted to be placed about the plant to be protected. The method of using the protector is clearly shown in my prior Patent No. 1,117,265, granted on the 17th day of November, 1914.

Having thus described the invention, what is claimed is I A plant protector embodying a tubular casing provided at one extremity with upper and lower projecting ears having ap In testimony that I claim the foregoing as my own, I have hereto'afiixed my signature in the presence of tWo Witnesses.

preaching free ends, the terminal edges of the ears being inclined and being disposed in approximate parallelism; and a closure the opposed edges of Which are seated in the ears, the closure being insertible into the ears between the inclined edges of the ears when the closure is tilted.
