Application filed August 25, 1916. Serial No. 116,770.
To all whom it may concern) Be it known that I, JOHN J MoGUoKm,
one end of the casing. And my improvements are particularly directed to means for preventing the rolling out of place of such flash lights when they are laid upon inclined surfaces.
In the drawings Figure l'is a side view of a flash light embodying my improvements; Fig. 2 is an end view on an enlarged scale looking to the right on Fig. 1; Fig. 3 is a view partly in section, and also on an enlarged scale, of the left hand end of Fig. 1; Fig. 4 is a sectional detail of a modified form of the anti-rolling ring; Fig. 5 is a front View of a modified form of the antirolling device; Fig. 6 is a vertical, sectional view of the same, showingthe retaining lugs bent in; Fig. 7 is a' front view of the same, showing the lugs in the same position as in Fig. ,6; F igs. 8 and 11 are front views of modified forms of the anti-rolling device;
Fig. 9 is a vertical, sectional view, and Fig.
10 is a partial front view of another modification of the anti-rolling device.
Similar reference numerals designate similar parts in all the figures.
1 is a conventional, cylindrical body of a flash light, which is provided with the flared end 2 carrying the usual thread 3 and provided with the lens 4 held in place by the flanged screw collar 5,
6 is a supplementary collar-like element, which is provided, upon a rounded circumference, with portions which project beyond the circumference of a true circle; and these projections may be either formed by the angles made by plain surfaces, as shown in the polygonal forms illustrated in a number of the figures; or they may be in the nature of knobs or curved projections, as illustrated, for instance, in Figs. 8 and 11. Whichever form is adopted its function is to prevent the rolling ofv the flash light to such as the Fig. 1,may be used,
' lay it .down upon sloping which it is attached. And the attachment maybe made in a permanent manner, as, for instance, by crimping a flange 7 of the anti-rolling attachment around thefiange 8 of the conventional, threaded collar; or by turning in lugs 9, 9, as in Figs. 5, 6 and 7, around the flange 8; or by forming the antirolling attachment with gripping elements turned in prongs 10, 10 of Figs. 9 and 10, which will bear against and around the collar 5', if the element 6 is shoved over the collar, and will hold the element 6 detachablyattached to'the collar; or the screw threaded collar 5 may be made integral with the element 6 as illustrated in Fig. 4, in
which case a separate, conventional collar may be dispensed with.
The opposite end of the flash light may be provided with a smaller anti-rolling device, similar to that used upon the reflector end ;ora modified form, such as shown in wherein a cap having a-polygonal flangell carries a screw threaded sleeve 12 which takes the place of the ordinary cap upon that end of the flash light body.
By means of my improvements I am enabled to simply, cheaply and effectively provide, the ordinary flash light holder with ananti-rolling attachment which is'\ both attractive in appearance, easy ofvapplication, and effective in operation, and which will materially increase the convenience of the flash light holder in use, because the user, when employing the flash light holder, may
surfaces of ordinary pitch without fear of its rolling out of position to its possible injury and to his inconvenience.
. Havingthus described my invention, what I claim and desire to secure by Letters Patent of the United States is 1. The combination, with a cylindrical flash-light holder, of a unitary, lens-retaining and anti-rolling device having an external contour other than cylindrical.
2. The combination, with a cylindrical flash-light holder, of a detachable, unitary, lens-retaining and anti-rolling device having an external contour other than cylindrical.
3. The combination, with a cylindrical flash-light holder, of a detachable, unitary, lens-retaining device having a plurality of anti-rolling elements protruding therefrom,
and a detachable, end-closing cap having a plurality of anti-rolling elements protruding therefrom.
4. The combination, with a cylindrical 5 flash-light holder, of a unitary, lens-securing device having a plurality of anti-rolling elements protruding therefrom.
5. The combinatlon, with a cylindrical flash-light holder, of an anti-rolling device 1 provided with flexible, metallic elements for attaching it to the flash-light holder.
6; The combination, with a cylindrical flash-light holder, of a lens-holding collar and a sheet metal, anti-rolling device having a noncylindrical external contour and being 15 provided with flexible elements whereby it is secured in a unitary relation with the lensholding collar.
