Brume-tion of letters Patent, Patented J une 2d., 1911., appuoanoamea naamw s, i911. aerial no. .-'2

To all @einem may comme: .l Be it known that I, Josn'PH BOLT', a citlzen of the United States, residing at Brooklkyn, in the county of. Clay and State of. lorida, have invented a new and useful.

Plant-Protector, of which the following 'is a specification. y My invention relates to plant protectors,

and particularly to that type of protectors; adapted to be placed over Ayoung plants 'to protect the same from extreme heat or cold,

will be durable, and which may be shi ped knocked-down and folded into s ape when required for use, or disconnected and packed away for future use.

The invention consists of a sheet of flexible material, preferably waterproofed, folded to form a'cover, land a wire support' bent at its upper. end to form a clip adapted to enga-ge the top of the cover, and a cli slidably mounted on the support and adapte to engage the lower edge of the cover and retain the same in position on said support, the extreme lower end of the support provided with a means for anchoring the same in the ound.

With lthese and other objects in view, the

invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and ointed out in the claims hereto ap ende it being understood that various c anges in the form, proportion, size and minor details-of construction, within the scope of the appended claims, may be resorted to without de arting from the i) the advantages of the invention.

Referring to the drawings, Figure 1 is a perspective view of the device complete and shown in use. Fig. 2 is a vertical sectional View of the same. Fig. 3 is a plan view of the blank forming the cover before being folded into shape. Fig. 4 is a detail-view of the upper endl of the cover showing the same folded and engaged by the clamp on the upper end of the support. Fig. 5 is a.

pers ctive view of the support showing the iitegral clamp at the top and the slid- -able clamp at the bottom. Fig. 6 a side view of the' integral clamp, and, Fig. 7 is a view of a modification.

In the drawings, 8 indicates a blank of paper, wood veneer or other suitable flexible material cut in Ithe sha e of a semicircle, and having a'small ho e 'cut out at the center, forming a semicircular notch, '9.

The semicircular blank 8 is adapted'to be folded in the shape of a conical cup or cover open at its apex, the radial straight edges of the same overlapping each other, 'and held together in a manner hereinafter 'de- L scribed. One of the objects of my invention Ais to 10 is a support yof any suitable material, but preferably of wire, the lower end of which is adapted to be inserted in the ground and at its up r end bent back u n itself to form 'a dbewnwardly exten mg elongated loop which is adapted to enter the opening, formed by the cut out portion 9 at the apex of the conical protector 8 and clamp the upper ends of the overlapped edges together, said loop having parallel spaced sides 11 and 12 the side 11 connected at its upper end to the support 1'0 .by the curved or loop portion 13,y and the sides 11 and 12 bein connected at their lower ends by the curve or loop portion 14. The sides 11 and 12 are also parallel with the supporting rod 10 but are spaced on each side thereof. The lower end 14 of the loop is preferably curved outwardly and spaced a short distance from the supporting rod 10, thus providing an easy entrance for the overlapped edges of the protector into said loop. The upper end of side 12 projects slightly above the loop 13 connecting side 11 and supporting rod 10, thus providing a handle or linger piece 15 by which the device a a whole may be moved from place to p ace. I

'Slidably mounted on the supporting rod l0 is a clip or retainer in the form of an upwardly projecting elongated loo having parallel spaoedsides 16 and 17 t e lower ends of which are spirally wound as at 18 around the supporting rod 10, providing an eye or Vguide through which the supporting rod 10 extends. The sides of the loop are arranged `on each side of, and are disposed in a plane common to that of the supporting rod 10. Thus it will be readily seen that engaging members or clamps for'both the top and bottom of the overlapped edges of the cone have been provided.

In assembling the device, the operator folds the blank into the form of a cone or protector havin the radial straight edges of the same over ap ing. Grasping the supportin rod by the r piece 15 at the upper en thereof, andp acing the downwardly extending elongated loop toward the protector, forces the loop downwardly through the opening 9 thus clamping the upper ends of the overlapped edges between the said loop and the sup rting rod 10. Still holding the support y the finger iece 1,5, the operator with the other han grasps the sliding loop at the lower end of the support by its spirally wound portion or eye 18, and positioning the loop .so that it will enter the inner side of the conical protector while the protector lies flat against the supporting rod, slides the clamp upwardly on the rod 10, thus securely bindlng the lower end of the overlapped edges between the supporting rod 10 and the sliding loop clamp.

It will be observed from Fig. 2 that the I overlapped edges of the protector are clam ed together on the sup ort, at the top and ottom ends thereof, an are prevented from bul ing outwardly by the supporting rod 10 w ich extends on the outer side of the protector and parallel to said overlapped edges. The support 10 is provided at its extreme lower end with a ground anchoring means in the form of a lug or projection 19, preferably formed by bending said rod outwardly or at right angles.

A modified form of sliding clamp is shown in Fig. 7, and is in the form of an elongated metal plate 20, provided at its lower ends with a struck up portion 21 which provides a longitudinally extending aperture through which the supporting rod 10 is adapted to extend.

. It will be readily observed from Fig. 2 how the im roved protector is placed over a plant. T e support is preferably forced into the earth, to the Windward of the plant so that the wind in striking the protector will force the same downward over the plant thus protecting the same from the force of the wind, the curved or bent anchoring lug preventing the support from being withdrawn from the earth by the force of the wind. In extreme cold weather loose soil may be thrown up around the lower edges of the protector to prevent undue draft through the same, the o ning 9 at the top of said protector provi ing ample ventilation for the plant.

Having thus described my invention, what I -claim as new and desire to secure by Letters Patent is:-

1. In a plant protector, the combinatlon of a conical cover, a support for said cover,

clamping means integral with said support for engaging one edge of said cover and clamping means movable on said support for engaging the other edge of said cover.

2. In a plant protector, the combination of a conical cover consistin of a sheet of flexible material having over apped edges, a support for said cover com osed of a wire bodyI arranged along one si e of the overlapped edges and having its upper end formed with a 'rigid clip opening downwardly and adapted to be slipped into engagement with the overlapped edges at the up er end, and a movable clip opening upwar ly and slidably mounted on said wire body so as to engage with the overlapped edges at the lower end, the lower extremity of the wire body being turned outwardly at an angle in a direction awa'y from the cover, for the purpose .ing a handle, and an upwardly extending and upwardly open loop slidably mounted on said support and adap't'ed to engage the lower edge of said cover and clamp the same between said loop and support, said loop having parallel s aoed sides arranged one on each side of said support, the lower ends of said loo encircling said support to provide a gui e for said loop.

4. In a plant protector, the combination of a conical cover consisting of a sheet of iiexible material having overlapped edges and open at the top, with a support for said cover arranged longltudinally along one side of the overlapped edges, an integral clamp provided at the upper end of the support to enga e the up r end of the overlapped edges, and a slida le clam mounted on the support and adapted to lie brought into engagement with the lower end of the said overlapped edges.

In testimony, that I claim the foregoing as my own, I have hereto atiixed my signature in the presence of two witnesses.
