To alluilwmitmay concern: 1

Be it known that I, Dams Hnnnr OMEARA, a'citizen of the United -States,

residing at Detroit, in the county. f'W'ayne and State "of Michigan, have inventedxcen.

. tain new and useful Improvements in Mag nifiers, of which the fo cation.

The present inventionrelate's to an improved magnifier and has particular reference to a device wherein the lens may be lowing is a speci raised and lowered with respect to the ob swung into an operative position easily and a quickly when desired.

Another important object of the invention is to provide a colla sible magnifier wherein the lens is carrie by amadjustable supporting memberwhereby the lens may be moved to and from the objects viewed through the lens while at the same time the angle of the lens with respect thereto may be adjusted to s'uitthe needs of the user. 1

Another important object of the invention is to provide a ma nifier which is articularly well adapted for use as a rea ing glass, the said magnifier being of such a nature that it may be collapsed and carried about without any difficulty.

Other objects and advantages of the invention will become apparent during the course of the followin description.

In the drawings, w erein like numerals are employed to designate like parts throughout the same:

Appllcationflletl April 14,1924. Serial no. 700,429.

' bodiment of the invention, the numeral 10 designates,in Figure 1, .oneform' of base 'whichis used in connection with In magnifier.- In this instance the base 10 1s in the form-of an annular band which, however, may be circular or of other cross sectional confi ration. In Fi re 1 the base. 10 is provided with the iametric'ally opposed ears 11, to which arepivotally or hingedly connected the lens supporting brackets 12. The brackets 12 are connected to the ears 11 by means of suitable bolts, pins, or the like 13.

The .opposite ends of the brackets 12 terminate in the annular extensions 14, which extend in substantially parallel relationship to each other. The lens roper of the magnifier is designated by the numeral 15 and is retained wlthin a suitable rim, or the like,

16, which is provided with the outwardly extending pro ectionsl7 which are adapted to be hingedly arranged between the angular extensions 14 of the bracket members 12. A pin or the like 18 is provided to permit of a pivotal movement of the lens 15 and frame 16. The frame 16. is. preferably of the split kind so that the .lens 15 may be removed or replaced as desired, while the ends of the rim 16 provide the necessary extensions 17 by which means the lens and frame are hingedly or pivotally connected to the lens supporting brackets 12.

It is to. be noted that due to the arrangement of the lens supporting brackets 12, angular extensions 14 and pro'ections 17, the magnifier may be colla so when not in use. This will permit 0 easy carrying of the magnifier, where the magnifier is designed and used for reading purposes. However, the magnifier is not restricted to use as a reading glass, as it may equally well be used wherever magnifiers haveheretofore been used.

. In Figure 2 of. the drawin s a slight modification is shown wherein t e supporting bracket 19 is. hingedly connected or mounted upon the Base 20 as at 21. In this instance no additional ears are provided, the bracket. 19 being pivoted directly through the frame 20. In this instance the lens 22, which is carried by the frame 23, is likewise pivoted as'at 24 to the lens supporting bracket 19. As is shown in dotted lines in Figure 2, the lens 22.and frame 23 may I upon the ob'eet seen therethrough in accordance with t e specific requirements of the user as well as the angle of the lens with respect to the base, epending upon the position of the user.

In Figure 3 the base 25 is preferably of a semicircular configuration, while the lens.

supporting brackets 26 are pivotally connected thereto as at 27. It is to be understood that the shape of the base 25 is not necessarily semi-circular. In this instance to provide means for rigidly supporting the lens in adjustment, a handle 28- is carried by the base 25 which acts as a brace as well as a handle. By having the base substantially of the configuration as shown, the lens may be moved relatively close to the object viewed without the base interfering, as at least half of the portion under the lens is devoid of the base member.

In Figures 4 and 5 is shown a slight modification of the magnifier shown in Figure 1, in that the lens 29 is angular instead of round. This is likewise carried by the lens supporting brackets 30, which brackets are supported by the base 31. The magnifier may be collapsed and placed within the case 32 and thus carried around conveniently, while at the same time it may be removed from the case and set up into an operative position very puickly and easily.

' In use the base 10 is p in proximity to the ob ect with which the magnifier is to enlarge, while the supporting brackets 12 are moved until the-lens is the desired distance from the object, after which it may be tilted, if it is necessary, to

- obtain the desired angular adjustment with the object tobe enlarged or magnified. By having the base supporting brackets and lens frame hingedly associated it is possible to obtain any adjustment required, so that anyone may focus the reader for his own particular use. After the adjustment has been made the parts may be locked in the desired position and used indefinitely, after which they may be loosened and collapsed to facilitate carr ing thereof.

It is to be un erstood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same and that various changes in the orting aced upon or held shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

In Figures 5 and 6 the magnifier is shown as bein provided with a handle which is adapte to be slid into and out of an operative position. through the members 34 and has stops 35 formed thereon to prevent separation of the base' 31 and the handle 33. It will be seen that when this slidable handle with the case is in use the handle is pulled out and grasped so as to facilitate movement of the magnifier over or upon the object magnified. When not in use, the handle 33 is slid along the frame so as to enable the magnifier to be slipppd in the case 32 until it is desired to use t e same again.

Having thus described my invention, I claim:

1. In a device of the character described, an open frame, a second frame within the The handle 33 is received first frame, having a contour parallel to the first frame, a hinge connection between the frames and a lens hinged to the inner frame adapted to lie therewithin when folded on its pivot.

2. .In a device of the character described, an open frame, a second frame within the first frame, having a contour parallel to the first frame, a pair of hinges diametrically arranged uniting the two frames, and a lens within the second frame pivoted thereto, adapted to lie within the second frame when folded on its pivot.

3. In a device of the character described, an open frame, a second frame within the first frame, having a contour parallel to the first frame, a hinge between the frames, a third frame hinged to the second frame and adapted to lie therewithin, and a lens in the third frame.

4. In a device of the character described, an open frame, 'a second frame within the first frame having a contour parallel to the first frame, a hinge between the frames, a'

the first frame.
