SPRING DEVICE Filed liarch 10, 1926 UNITED ST "Pa t'ntedQM ar. 4, 1930 JOHN WEICHSEL, OF NEW YORK, N. Y.
SPRING nnvron f Application filed March 10, 1926; SeriaINo. 93,743.
I I The present invention relates to spring de vices and especially to those employing coil springsand aims to provide certain improve ments therein.
The primary objectv of the present invention is to provide means for protecting coil 7 'or 'hel'ical'springs against the entranceinto or between the convolutions thereof of dust, dirt, vermin or the like, without in any way impairing the actionof the springs. A further object is to provide a spring device of .the type described in asimple, efficient and practical manner. 7 Still another object is to provide an improved method of enclosing a coil or helical spring within a protective element. Theforegoingand additional objects I accomplish by making the protective element as asomewhat flexible extensible casing, which I preferably form by spirally winding a ribbon with its edges in overlapping relation, thereby adapting it for relative movement. The ends of the protective element are preferably I. formed to cooperate .with the ends of the plates other features of novelty, whichwill,
spring to provide suitable anchoring means forflthe spring. The invention also contembe hereinafter more fully described In the accompanying drawing, I have shown two preferred embodiments of my invention wherein:
"Figure 1 is a perspective view of the spring devlce.
, tially completed form.
Figs. 4 and 5 are details of the manner in which the anchoring means of the spring device areformed.
Referring first to Figures 1, 2, land of the drawings, let A indicate a coil or hellcal j spring of any desired or conventional form having its end formed as a hook B which is disposed in a plane substantially at a right I i angle to the planes of the convolutions of the .spring. Surrounding the spring A is the protective elementC which as herein shown is in theform of a spirally wound ribbon, the
edges'iof which are in overlapping relation and adapted for relative m'ovement,which it will be? appreciated is essential to accommodate the extension and contraction of the spring use when subjected to strains. The degree of overlapping of the ribbon edges is preferably such as will permit maximum normal distension of the spring without uncovering the same. Preferably this ribbon is of metal, but it will be understood that other material such as-fabric, fibre or the like if properly treated may be used with equally good results. I i v I The end portions of the protective element C are preferably flattened after being positioned over thesprin'g-as shown at D in Fig. 4, after which the flattened portion extending beyond the hook of the spring is turned down asshown at E in Fig. 5." The turned down flattened ends are thereafter pierced to provideopenings Fwhich are just below the bight of the hook B with which it cooperates to provide a reinforced anchoring means for the spring device. a I a In Fig. 3-1 have shown an alternative form of protectiveelementC which consists of a pair of ribbons, spirally wound in opposite directions with their edges overlapping as hereinbefore described or a single ribbon rewound on'itself. A protective element of this type c doubly'insures against the entrance of deleteriousmatter into or between the convolutions of the spring. I
The'end portions of the element C" may be formed in; a like manner as'that described in connection with the embodiment of the invention shown in 'Figs, 1, 2, 4c and 5.
"The protective elements C and C may be formed either independently of the sprin element A or wound directly thereover. I prefer to make them separately from the springs and have found that they may be efiiciently made by spirally winding the ribbon over a mandrel to form long tubes which are subsequently cut up into the proper lengths to fit over the springs A, after which the end portions are finished off as hereinbefore described and illustrated in Figs. 4 and 5.
' The spring devices of my invention it will be understood may have varied and almost Cal - universal application and I therefore do not Wish to limit my invention to any specific ap-' plication therefor.
It Will also be understood that While I have shown and described two preferred embodiments of my invention, I do not wish to be limited to the specific structures'disclosed since modifications thereof may beresorted to.

What I claim is: c
' 'WlthOllt departing from the spirit of, the in- 1. A spring device comprising a coil spring 7 and a one piece extensible metallic housing entirely enclosing said spring having a normal length approximately equal to the normal length of the spring and being adapted to accommodateitself to variations in the ef- 7 i tective length of'the spring when it is stressed and relaxed. i I 1 r 2. A spring device comprising a coil spring 7 and a. protective element'therefor, said 'protective element'comprlsinga ribbon spirally Wound around said spring and entirely'en closing the same, the edges of said ribbon;
being in overlapping relationand adapted for relative telescopic movement to accommodate the protective element to variations in the efie'ctive length of the spring When it is stressed and. relaxed.
I 4. A spring devlce comprislng a C01 substantially at right angles'to the planes of the convolutions of the springs and a protective element entirely enclosing said spring,
said protective element comprising a ribbon spirally Wound around the spring and entirely enclosing the same, the edges of said ribbon: being in overlapping relation and adapted for relative telescoping movement to accommodate the'protective element to variations' in the effectivev length of the spring when it is stressed and relaxed, said protective elementhaving its end portionsfiattened to embrace the end portions of the spring 7 JOHN WEICHSEL;
