This invention relates to an improved reading apparatus and one object of the invention is to so construct the apparatus that a book, newspaper or the like may be supported in such a position that printed matter may be seen through a magnifying glass forming part of the apparatus and to also provide a light so mounted that the newspaper or book will be illuminated without injury to the eyes of a person using the apparatus.

Another object of the invention is to so construct and mount the. holder by means of which the book or newspaper is to be supported that it may be shifted along a base towards or away from the magnifying glass mounted at the front of 15 the base and thus permit proper focus to be obtained when using the reading apparatus.

It is another object of the invention to permit a book holder forming part of the carrier to be shifted vertically and also transversely of the base and thus permit the book or newspaper to be shifted vertically or transversely and supported in the adjusted position wherein printed matter in a certain location upon the newspaper or book may be seen through the reading glass. This also 5 permits the book or newspaper to be shifted horizontally as it is read and progressively move reading matter in a line into position to be seen clearly through the glass.

Another object of the. invention is to so con- .30 struct the mounting for the book or newspaper holder that portions of the mounting may be eX- tended and engage backs of large books or papers.

It is also an object of the invention to so construct the reading glass that it may be detachably 35 mounted in position over the front end of the 40 through the base and auxiliary handle members applied in case the handle formed as part of the reading glass is not of the proper length to permit a person using the reading apparatus to easily see glass.

Another object of the invention is the provision of improved means for mounting the lens in the frame of the reading glass and, in addition, to provide an auxiliary lens which may be supported 5 from the rim of the main reading glass and thus permit extra magnication of the printed matter in case it is printed in very fine type or a person using the apparatus has very weak eyesight.

Another object of the invention is the provision of a light including a bulb mounted in an electric socket carrying a reiiector for directing rays of light towards the book or newspaper resting upon the holder and to associate with the 55 reector a color screen through which rays of light from the electric bulbmust pass and thus cause the light rays directed upon the book or newspaper to closely simulate daylight. By this arrangement, reected glare from a newspaper or the pages of a book will be eliminated and eye strain prevented.

Another object of the invention is the provision: of a reading apparatus of such construction that it may be used either by a person sitting at a table or by a sick person reclining in a bed, provision beingmade for supporting the base of the apparatus at an angle such that the person using the apparatus may very easily see through the reading glass.

`The base l of this improved reading apparatus may be formed of wood or any other desired maimproved readterial and has widened front and

rear end portions

2 and 3 which project from opposite sides of its intermediate portion. By so forming the base, it may rest upon a table, bed or other surface and the extended front and rear end portions will serve to prevent transverse tilting of the base and mechanism carried thereby. Auxiliary blocks or strips 4 and 5 are formed integral with or secured in any desired manner upon upper faces of the front and rear end portions of the base and these blocks or extensions carry rods 6 which extend longitudinally of the base over the intermediate portion thereof with their end portions passing through openings formed in the blocks and carrying securing nuts 1 by means of which they are held firmly in place and prevented from slipping longitudinally out of engagement with the blocks. In some instances, it is desired to have the base rest flat upon the table, bed or other surface upon which it is placed while at other times it is desirable to dispose the base at an incline so that the person using the reading apparatus may-more easily obtain a clear view through the reading glass. Therefore, there have been provided yokes or

props

8 and 9 which are carried by the forward end portion of the base. Each of the props is formed from a length of metal rod bent in spaced relation to its ends to provide a bridge portion and side arms, the arms I of the prop 8 being shorter than the arms II of the prop 9 and both props having their arms terminating in inwardly bent portions forming pintles rotatably engaged in sockets formed in end faces of the widened portion 2 of the base. The short prop 6 when notin use isrswung upwardly above the base and forward block 4 and when it is to be used it is swung downwardly from the raised position to the lowered position indicated by dotted lines in Figure 2 in which position its arms make contact with pins I2 projecting from ends of the enlarged portion 2 of the base and located substantially midway between but in a slightly lower plane than the pintles of the two props. It will thus -be seen that forward f movement of the shorter prop when in a lowered position for use will be limited and this prop will support the base at an incline. When the taller prop is in use, it is swung downwardly from the inoperative or folded position in which it projects forwardly under the base, as shown in Figure 1, to a lowered position in which it extends downwardly from the base at a rearward incline with its arms engaging the abutment pin, as indicated by dotted lines in Figure 2. Further rearward movement of the prop 9 when swung downwardly to the lowered position is limited by engagement of its arms with the abutment pin and the base will be supported at a steeper incline. Clips I3 formed of resilient metal and secured against ends of the widened forward portion 2 of the base are provided to engage the arms of the tall prop 9 when it is swung forwardly and upwardly to the folded or inoperative position and retain the prop in the folded position.

The reading glass, which is indicated in general by the numeral I4, is carried by the forward block 4 and located midway the width of the forward end portion 2 of the base so that a person using the reading apparatus and looking through the lens I5 of the reading glass may easily obtain a view of the newspaper, book or the like carried by the object support indicated in general by the numeral I5. This reading glass is provided with a lens of such diameterthat the person using the reading apparatus may use both eyes when looking through the lens. Therefore, eye strain will not be caused by the user of the apparatus attempting to look through a lens which is too small. The lens which may be referred toI as a binocular lens is six inches in diameter although it may be of any diameter desired and may be double convex, plano convex, concavo convex, plano convex cylinders with convex surfaces together and axis opposite, achromatic or nonachromatic, or completely corrected anastigmats, or any combination of curve or foci that will give atness of field of the observed object, but always of sufficient diameter to permit binocular vision.

In order to mount the lens in the frame I'I which is formed of a metal rod, there has been provided clips I8, each of which is formed from a strand or strip of resilient metal. These strands are coiled about the metal rod from which the frame I'I is formed, as shown clearly in Figures 4 and 6, with end portions of the strand projecting inwardly radially of the frame to form hinges I9 disposed in position to engage opposite faces of 'the lens and thus firmly grip the lens and prevent it from moving out of its proper position in the frame. The metal rod from which the frame I'II is formed is bent to define a circular frame of the proper diameter to receive the lens and end portions of the rod are bent to project radially of the frame in contacting engagement with each other, as shown in Figure 4 and form a shank 20 engaged in a socket 2| formed in the upper end of a handle 22. This handle may be formed of wood or any other desired material and of any desired length and diameter and at its lower end is formed with a socket 23 to receive the shank 24 of a mounting fork, the arms or tines 25 of which project from the lower end of the handle longitudinally thereof and when engaged in sockets 2li formed in the slots 4 support the reading glass in an upright position. Therefore, a person using the reading apparatus does not need to hold the reading glass but may sit in a chair or recline in a bed and look through the reading glass. In case the length of the handle 22 is not sufficient to support the lens at such an elevation above the base that a person can conveniently see through the reading glass, an extension block 2, such as shown` in Figure 9, may be employed. ThisV extension block has sockets 28 leading from its upper end to receive the prongs or arms 25 and at its lower end the extension block carries a fork 29 corresponding in construction to the fork of the handle and having its prongs or arms 35) projecting from the block longitudinally thereof in rposition for engagement in the sockets 26. When this block is applied to the handle, the lens will be supported in an elevated position and it is to be understood that any number of these blocks may be provided, the blocks of the set being of different lengths. By removing the reading glass from the blocks 4 and grasping it by its handle, it may be used as a hand glass.

When elderly persons or persons having greatly impaired eyesight are using the reading apparatus, it is desirable to additionally magnify printed matter which is to be read. It is also sometimes desirable to provide means for additionally magnifying the reading matter when it is printed in very small type. In such cases, an auxiliary lens 3l which is smaller in diameter than the lens I5 is mounted at the front of the main lens, as shown in Figures l and 2. This auxiliary lens is preferably of approximately onehalf the diameter of the mainy lens land ground to norrespond to the grinding of the main lens but it is to be understood that the auxiliary lens may be ground :in any manner desired. This auxiliary lens .or magnifying element is mounted in a

metal frame

3,2 by fasteners 33 corresponding in construction to the fasteners I8 and from the rim y32 .extends mounting arms 34 which project forwardly in diyerging relation to each .other and have their terminal portions bent to form hooks or bills 35 adapted to 4engage about the frame I1 of the main lens .and securely but detachably hold the auxiliary lens in an operative position where it is centered with respect to the main lens. In view Aof the fact that the arms 34 Aare formed of resilient metal, the hooks or bills may be very easily engaged with or detached from the frame of the main lens .and when in engagement therewith firmly grip it.

During use ofthe reading apparatus, it is desirable to have the book, newspaper or other object illuminated so that vthis object which is supported -by the carrier I6 may be` clearly seen. Therefore, there has been provided an electric socket 31 which is mounted above the reading glass by a clamp 38 engaged about the socket and also engaged about the upper portion of the rim or frame l'lof the reading glass. This socket 37 extends circumferentially of the reading glass at a tangent to the frame l' and carries a cupshaped reflector 39 which is formed of metal and has -its front open so that light from the bulb 40 will be directed forwardly towards the newspaper, book or the like supported by the carrier I6 and illuminate the same to such an extent that it may be clearly seen and easily read or inspected. A light filter 4I which may be formed of glass or any other light penetratable material desired is mounted at the open front of the reflector and provided with a rim or frame 42 carrying hooks or bills 43 which project rearwardly and are formed of resilient material so that they may be snapped into engagement with the bead 44 formed about margins of the open front of lthe reector. Therefore, the filter will be detachably mounted and very firmly held in place when applied to the reflector. This filter is tinted an appropriate color which will cause undersirable rays from an electric bulb to be absorbed and light having daylight qualities shown upon the book or other object to be inspected or read.

Due to the construction of the magnifying lens which, in addition to its spherical power, is comi posed of two approximately 'l1/2 prisms, bases in the leyes of the observer incline to diverge when looking at an object at reading distance, or assume a position of parallelism which would be practically the same as when looking at infinity, thus -reducing the necessity for muscular convergence. Then, due tothe high magnification and illumination of the object, the accommodative effort is also greatly relaxed. Thus, the strain on the two main functions in the act of seeing, accommodation and convergence, are greatly lessened and the observer sees with comparative comfort. This effect is extremely advantageous to persons of advanced years in whom these two functions are naturally weakened and impaired, and of great benefit also to the young whose eyes are weak due to heredity or other causes.

When the supplementary magnifying lens is used, only monocular vision is permitted, but the magnification, .in addition to that of the larger lens, is increased 100 to 200%. This sup-- plementary lens feature is particularly advantageous and helpful to persons who have vision remaining in only one eye and in which the visual acuity is very low.

The object carrier, indicated in general by numeral 16, has a standard 45 formed of wood or other desired material and having at its lower end a foot 46 so that when the standard is secured upon the base block or carriage 4l by screws passed upwardly through the base and into the foot and lower end of the standard, the standard will be rmly secured upon the base. This base or carriage has passages or bores 48 formed through it to slidably receive the mountn ing rods or tracks 6 and a forwardly projecting screweye 49 is carried by the base between the mounting rod so that by grasping this screweye the carrier may be slid longitudinally upon the rod and thus shift the object carrier towards or away from the reading glass. Therefore, a book, newspaper or vthe like may be disposed the cor rect focal dista-nce from the reading glass to accommodate the apparatus to the condition of the eyesight of the person using the same. Cross bars 50 in the form of metal tubes extend transversely of the standard with their intermediate portions extending through grooves or recesses 5I formed in the front face of the standard where they are secured by screws 52 which pass through the tubes as shown in Figure 'l and are screwed tightly into the standard. Openings 53 are formed in the tubes at the front thereof in order that the screws may be set in place and a screw driver passed into the tubes to turn the screws tightly into the standard. Extension rods 54 which are also formed of metal tubes and have heads or knobs 55 at their outer ends are slidably received in the cross bars to serve as extensible sections for the cross bars and permit a very large book or a large sheet of paper such as a big blue print or the like to be supported and braced against rearward movement. Clips 56 which are formed of resilient metal are secured in the tubular extension sections 54 by rivets 5l and extend longitudinally of the extension sections with their free end portions projecting through openings 58 to bear against inner surfaces of the tubular cross bars and frictionally hold the extensible sections in adjusted position.

The carrier 59 upon and against which the book or newspaper directly rests is preferably formed of sheet metal, although any desired material may be used, and consists of a flat sheet having its lower portion bent to form a forwardly projecting ledge or flange 60 terminating at its front in an upstanding lip 5|. It will thus be seen that a book or paper may be set upon the ledge 59 back of the lipy 6I or with a portion of the book resting upon the lip and the book or paper will rest against the front face of the fiat sheet from which the carrier is formed. The book o1' paper may be disposed either perpendicular to the ledge or at a rearward incline. In order to maintain a book or paper in engagement with the carrier and prevent pages of a book from turning, there have been provided retainers 62 formed from strands of resilient wire. Each strand is coiled intermediate its length to form a helical spring 33 having

arms

64 and 65 projecting from it in straddling relation to the upper portion of the sheet metal carrier and by referring to Figures 2 and 3 it will be seen that the rear arm 54 terminates in eyes 66 through which rivets or equivalent fasteners are passed to pivotallymount Athe retainers and thus permit the retainers to be swung transversely of the carrier to such a position that the longer front arms 65 which terminate in large eyes 61 at their lower ends may be disposed in overlying engagement with a newspaper or the pages of a book and thus retain the paper or book in its proper position upon the carrier and prevent pages of a book from accidentally turning. Bills or prongs 68 project rearwardly and downwardly from the metal sheet from which the carrier is formed and are spaced from each other transversely thereof so that they may engage over a selected cross bar 5B and support the carrier. By providing a number of cross bars, the carrier will be well braced against rearward strain and also permit the carrier to be shifted vertically and supported in the adjusted position with the bills engaged with a predetermined cross bar. It should also be noted that the bills.. are so spaced from each other that they engage a cross bar at opposite sides of the standard and, therefore, the carrier may be shifted transversely of the base l and portions of a line of printed matter progressively moved into position to be seen through the reading glass or a desired portion of a blue print or the like moved into position to be seen through the glass. As additional means for maintaining the carrier in operative engagement with its support and permit vertical and horizontal adjustment thereof, there has been provided a staff 69 formed of a metal tube and having its lower end pivotally mounted by a fastener 79 which passes through an eye formed at the lower end of the shaft and into the standard 45 close to the foot 46 thereof. This staff extends upwardly with its intermediate portion bent to project forwardly across the curved upper end of the standard, as shown at ll, and the upper portion of the staff projects upwardly, as shown in Figures l and 2. Since the staff is formed of a metal tube, an extensible section 'l2 may be telescoped into the upper end portion of the staff and when necessary drawn upwardly to a position in which it projects upwardly a sufficient distance to support the upper portion of a large blue print or the like which projects upwardly above the upper edge of the carrier. This extensible section 12 corresponds in construction to the extensible extensions 54 of the cross bars and is formed with a knob or head 'I3 at its upper end and will preferably be held in an adjusted position by a clip corresponding to the clip 56. By grasping the upper end of the extension or the upper end portion of the staff, the stair may be swung transversely of the standard about the fastener 70 and the sheet metal carrier which is anchored to the staff by the eye 'F4 will be shifted transversely along the cross bars. The cross strip 15 fixed to the rear face of the standard has its ends bent rearwardly to form abutments 16 to limit swinging movement of the staff. Positions which may be assumed by the carrier when shifted transversely are indicated by dotted lines in Figure 3 but it is to be understood that these positions do not indicate the full extent to which the carrier may be shifted. Rods or handles I1 which terminate in eyes 'i8 at their outer ends project from opposite side edges of the carrier for use when shifting the carrier transversely, in which case it will not be necessary to grasp the upper end of the staff or its extension when shifting the carrier along the cross bars.

In Figures l1 through 13, there has been illustrated an embodiment of the invention particularly adapted for use when reading or inspecting books and papers placed upon a table. In this embodiment of the invention, a standard 'I9 which may be of any height desired, is used and this standard has a large base 80 which may be formed integral with or separate from the standard. The base is preferably weighted so that it will maintain the standard in its upright position and prevent the weight of the reading glass and lamp carried thereby from causing the standard to tilt over. Circuinferentially extending grooves constituting annular `seats are formed about the standard in spaced relation to each other one above another and when a latch 82 carried by a block 83 is engaged in one of the grooves or seats 8|, the block will be supported at a predetermined height above the table or other surface upon which the base 80 rests. The latch 82, by means of which the block is supported, consists of a strip of stiff metal disposed radially of the block with its outer end portion projecting from the block and formed into la ngerhold 84 by means of which it may be easily grasped and slid radially of the block into and out of position to engage in the grooves or seats. Screws 85 serve as supports for the latch and as these screws extend through slots 86 formed longitudinally of the latch, sliding movement of the latch will be permitted. A pin 81 extends downwardly from the latch between the slots 86 for engagement by a spring 88. This spring consists of a strand Iof resilient metal having one end bent to form an eye through which a securing screw 89 passes and resiliency of this spring causes it to normally maintain the latch in the operative position in which its inner end will engage in a groove of the standard. By grasping the head 84, the latch may be drawn outwardly to a releasing position and the block shifted vertically upon the standard to approximately theelevation desired and upon releasing the latch, the spring will shift it inwardly to the operative position. If it is desired to prevent the block from turning about the standard, the set screw 9D carried by the block will be tightened until it has binding engagement with the standard between the grooves, as shown in Figure l2, but if it is desired to permit the block to turn freely about the staff after being shifted vertically thereon to an adjusted position, the set screw will be left loose.

In order to support the reading glass 9| which corresponds to the reading glass I4 and carries a source of illumination 92 constructed in accordance with that shown in Figure 4, there has been provided an arm or bar 93 formed of wood or metal and extending through a bore or passage 94 formed through the block 83 at the opposite sides thereof from the set screw 90. This bore or passage 94 extends through the block transversely of a radius thereof, and, in the present illustration, at right angles to the latch, and the block carries a set screw 95 which, when tightened, has frictional engagement withthe arm or bar to secure it in a longitudinally adjusted position and prevent rotation of the bar in the bore 94. The outer end portion of the arm or bar fits into a socket 96 formed in the rear inner end of the head 91 where it is secured by a set screw 98 and upon referring to Figure 11, it will be seen that at its outer or front end, the head is formed with sockets 99 to receive the prongs of the fork |00 carried by the handle IUI of the reading glass. This handle is formed near its rear end with a circumferentially extending groove |02 forming an annular seat to receive the 1 standard, an articlefcar'rier in front of said standlips or'anges- IU3 formed at outer or front ends of clamping jaws HM formed from strips or resilient metal and having their shanks forming portions disposed against opposedl portions of the head Sl. Slots lll' and M15 are formed in the Shanks of the clamping strips to receive the screws lill and set screws S and it will be readily apparent that when the set screws are loosened, the clamps may be slid forwardly longitudinally of the head and the clamps will be relieved of pressure by the set screws. Therefore, the jaws formed by the forwardly projecting portions of the clamps may move apart a sufficient distance to free the lips H03 from the groove |02 and the reading glass may be detached from the head. In a like manner, the handle of the reading glass may be applied to the head and the clamps then slid rearwardly and the set screws tightened a sumcient extent to cause the jaws to firmly grip the handle. It should also be noted that by loosening the set screws, the reading glass may be turned about the shank of the fork for angular adjustment about a horizontal axis and the set screws then again tightened or, if so desired, the angular adjustment just referred to may be obtained by loosening the set screw 98 and turning the head about the arm 93 or by loosening the set screw 95 and turning the arm in the bore or passage 94.

In Figure 14 there has been illustrated a simplied construction wherein the reading glass, which is indicated in general by the numeral [09, is directly applied to a base or support l l@ formed from a board of any desired length and width and which may be formed in accordance with the outline of the base I, if so desired. This base has a metal plate l H mounted in a countersunk seat H2 formed in the upper face of the base Where it is secured by a suitable number of screws H3 and in this plate and board are formed sets of sockets H4, H5, and l IB to receive the prongs H1 projecting from the handle H8 of the reading glass. The sets of sockets H4, are so drilled that when the prongs of the reading glass are engaged therein, the reading glass will be mounted in a perpendicular position, whereas the prong receiving sockets H5 extend forwardly at an incline and the sockets H6 extend forward at a greater incline than the sockets l l5. By this arrangement, the reading glass may be transferred from one set of sockets to another and the angle at which the reading glass is disposed regulated. While three sets of sockets have been illustrated, It will be understood that as many as desired may be provided and formed at any angle desired. By detaching the reading glass from the base, it may be held by its handle and used as a hand glass and the lamp socket left attached to the frame of the reading glass or removed therefrom if not needed.
