ROOKFORD, ILLINOIS, A CORPORATION DELAWARE PEG Application led May 7, 1927. Serial No. 189,528.

, This invention relates to pegs in general and more particularly to shelf pegs of the type used to support the shelves or trays in refrigerators and aims to improve generally I on such pegs.

The pegs heretofore customarily used for supporting refrigerator shelves have been threaded at their outer end and provided adjacent the inner end of the threaded portion with a circumferential shoulder adapted when the threaded portion of the peg Was projected through an opening in the refrigerator lining to abut against the inner surface of the lining which was clamped between this shoulder and a nut thr'eaded onto the projecting outer end of the peg. These pegs Were mounted or attached to the lining prior to its assembly in the refrigerator cabinet. The clamping nuts being disposed on the outside of the lining were, when the lining was in position in the cabinet, entirely .inaccessible With the result that if they became loose in use, they could not be tightened up again and not infrequently, they dropped ofi' entirely so that the peg becalne useless.

It is accordingly the principle object of this invention to provide a shelf peg capable of being used in connection With refrigerators or the like in which the nut is disposed on the inside of the lining Where it is accessible and can be tightened at any time should it become loose after assembly of the refrigerator.

Itis also an object of this invention to pro-v vide a peg of this type which may be-replaced from the inside of the lining or other support to which it is adapted to be attached.

Other and further objects of this invention will be apparent as the same becomes better understood from an examination of the specification and claims in connection with the accompanying drawings wherein,

Fig. 1 is a fragmentary sectional View showing the v vall of a refrigerator provided with a lining having attached thereto a shelf peg embodylng this invention.

Fig. 2 is a sectional view taken at the line- 2 2 of Fig. 1.

Fig. 3 is a perspective view of the shelf peg With parts omitted.-

Fig. 4 is a fragmentary elevational view taken from the outside of the refrigerator compartment lining, a modified shelf peg attached thereto embodying this invention.

Fig. 5 is a perspective View of the modified shelf peg with parts omitted.

Referring to the drawings more particularly, numeral 6 represents the outer shell of a refrigerator Wall having suitable insulation 7 and a sheet metal lining 8 spaced therefrom to provide an air space 9.

The lining 8 is provided with a rectangular or other shaped aperture as at 11 to receive a shelf peg represented generally by the number 10.

Pegs 10 arefpreferably made by taking sections of wire upsetting them at one end to provide an integral head 12 and an enlarged portion along the shank in proximity to said hea-d on which portion are subsequently formed the threads 13 and a rectangular'or other shaped portion 14 on the inner side of said head and corresponding to the shape of the aperture 11. The rectangular portion i4: cooperates With the aperture 11 to hold the peg against any rotational movement' tending -to Work the peg loose and also facilitates assembly by holding the peg against rotation While tightening the nut which will be hereinafter described. the peg is bent to form the hook portion 15 on a radius permitting the springwvasher '17 and also the nut 16 to be slipped onto the peg over the hooked end thereof.

The nut 16 is threaded on the threads 13 for clamping the edges of the lining 8 adjacent the aperture 11 against the head 12, a convex spring Washer 17 preferably being used between said nut and lining to prevent The inner end of the nut from Working loose and to form an opening through which e the shank passes.

air tight seal around the geg In the process of assem ly, the peg is inserted from the outside of the linlng 8 and is -attached thereto before the lining is secured in lace in the refrigerator. In the pegs usedp heretofore, a threaded nut was used in place of the head 12 and a shoulder was provided on the peg whichcooperated with said nut for clamping the peg to the lining, the nut being left-on the outside of the lining so that it was inaccessible after assembly and should the nut become loose,- it could not be retightened and it might even drop ofi' and fall down in the space 9. When my peg is used, the nut 16 can not possibly drop oi but should it become loose, it can readily' be tightened again, because it is on the near side of the lining 8 and accessible at all times.

' In Figs. 4 and 5, there is shown a modification in which the lining 8 is provided with a horizontally elongated 'aperture 18 in place of theaperture 11 and the peg is provided with an elongated head 19 m place of the round head 12 so that the peg can even be l installed from the inside of the refrigerator after the linin 8 has been secured in place. In installing tlgie peg, the elongated head 19 is inserted through the aperture 18 and the peg is then given a ninety degree turn. The nut' is then tightened as in the previous embodiment. When this modified construction is used, the entire peg may be renewed after the refrigerator has been completed.

I am aware that many details may be varied throughout a wide range without departing from the principles of this invention and I therefore do not wish to be limited t0 the details shown ordescribed.

I claim:

1. The combination with a refrigerator wall having an enameled surface, of a shelf peg having a shank extending through an opening in the yWall and provided with a head engaging one face of the wall, a nut threaded upon the shank, and a sealing device located between the nut and the enameled surface of the wall and provided with centrally 1ocated means to engage the nut and space it` from the enamel surface, said sealing device also provided with peripheral means engaging the enamel surface remote from the edge o f the opening to seal the opening and prevent cracking of the enamel around the edges of the opening.

2. A shelf peg for refrigerator walls and the like,` comprising a shank having one end portion provided with a head, the shank being screw threaded adjacent the head, a nut on the screw threaded portion of the shank', and a resilient sheet metal sealing device slidable upon the shank between the nut and the head and provided with a central boss or cifset for contact with the nut and to span the nature.
