Application filed October 9, 1917. Serial No. 195,550.
.To all whom it may concern:
Be it known that 1, WILLIAM S. HAMM, a citizen of the United States, and resident of Hubbard Woods, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Binders for Lenses, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.
The invention relates to binders applied to the margins of plates, such as the lenses of lamps, in order to secure a cushioning effect.
It has heretofore been the usual practice to fit upon the margins of such plates a piece of longitudinally split rubber tubing. This material is open to several objections. Because of the sulfur it contains the reflector, when of metal, becomes tarnished, and the rubber has a tendency to harden with age and to lose its cushioning action.
It has been proposed to use felt as a binder but difliculty has been encountered in securing to a plate especially when circular in form, a binder of this material which will smoothly overlap both faces of the plate and remain in place.
The object of this invention is to provide a binder of felt, or equivalent material, which may be easily and cheaply made and readily applied, and which will reliably remain in position.
The invention consists of a band, preferably endless, of pliable material, such as felt, having a longitudinal or annular series of apertures, preferably elongated.
In the accompanying drawings illustrating the invention,
Figure 1 is a detail of the blank from which the binder is formed;
Fig. 2 is a view in perspective of the completed band;
Fig. 3 is a face view of a lens with the binder applied thereto; and
Fig. 4. is an edge view, on a larger scale and partly in section, of the lens with the binder applied.
The invention is illustrated as applicable to a circular headlight lens. A strip 10 of material, such as felt, of suitable length to encircle the lens 11 wlth which it is intend- .ed ,to be used, is perforated throughout its length, as shown at 12, these perforations preferably being elongated and being as numerous and of such length as may be found most advantageous. The ends of the strip 10 are preferably secured together, as by means of stitching, as indicated at 13, and the length of the strip is such that when thus formed into a ring it is of slightly less diameter than the lens 11.
In applying the binder to the lens it is first fitted thereto throughout a part of the circumference of the lens, the margin of the latter following the line of the apertures 12. The ring is now slightly stretched to force it over the remainder of the circumference of the lens. As the tension is borne by the marginal portions they contract tightly against the side faces of the lens, to which they smoothly fit. The binder is thus securely held against lateral displacement without the use of cement, and the material intermediate of the apertures 12 cushions the edges of the lens.
While the binder is most efleotive when endless, it may be used as a strip, the removal of material along its median line by perforation facilitating the folding of the strip over the edge of the plate. While the apertures are shown as elongated this form is not essential, though preferable. Neither is the width of the elongated apertures of vital importance, though better results are secured by actually removing some of the material.
I do not limit myself as to the particular material to be employed, though so far as I am now aware felt is to be preferred.
I claim as my invention- 1. A binder for lenses or like plates comprising a band of pliable material having a lon 'tudinal series of apertures.
2. A binder for lenses or like plates comprising a band of pliable material having a longitudinal series of elongated apertures.
3. A binder for lenses or like plates comprising an endless band of pliable material of slightly less diameter than the lens to which it is to be applied, and being provided with an annular series of apertures.
secured together to form a ring of less di plates comprising an endless bend of pliaameter than the lens to which it is to be apble material of slightly less diameter than plied; v i :the plate to which itis 'to be applied, and 10 5. A binder for circular lenses or like being provided with an annulerseries 0f- 5 plates comprising a strip of pliable material "apertures. u I
