To llwkomitmwyconcem.' l

Be it known that I, ROBERT'M. SEARLE, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain 'new and useful Improvements in Copyholdferent portions of the work to the line guide,

for example: as when the work support is moved verticallyrelatvely to the stationary line guide as in U. S Patent No. 1,014,646, granted January 16, 1912, to R..B. Griihth An object of this invention is to associate with the copy holder a lens which will permit the magnification of the work adjacent the line ide so that small print and writing may e enlarged. Another object of the invention is'to provide for the illumination of the work ad'acent the line guide without producing a g are in the eyes of the user of the copy holder. A still further object of the invention is to provide in connecl as To these an the illuminating tion with the illuminating means, alight filter which will absorb certain of the rays of the illuminating means to 'give a light similar to dayli ht.

other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

ln the drawings:

Fi 1 is a front view. of a copy holder embodymg the present invention, parts being broken away; I'

Fig. 2 lis a side view of the copy holder;

Fig. 3 is an enlarged fra entary sec tionalview on the line 3- 3 ig. 1 showing means, the light filter being shown in dotte lines in lowered position;

Fig. 4 is a fragmentary view of the supporing mea'nsV for the lamp and the line 1 e; gFig 5'is a detail view of one end of the lamp casing and the line guide.

Flg. 6 is -a detail view showing the manner in which ventilation is obtained between the .lamp casing and the work support when the lamp casing is in abutment with the work support. l

This invention may be embodied in any 1919. serial No. 312,061.

copy holder where the line guide and a work support are relatively movable for the purpose of causing the line guideto point out the successiyelineof a piece of work. In the lllustrated'embodiment there is provided a fixed or stationary frame 1 on which the work supporting member or plate 2 is vertically adjustable. This work. supporting plate maybe moved step by stepv through a lever 3 pivoted at 4 and connected to another lever 5 which is pivoted Iat 6, the lever 5 besarme j ing connected through a rod 7 with a clutch l (not shown) -such arrangement being similar to that shown in the paten 4 to Grlfth No. 1,014,646 and bein-gdesigned to elevate the work support 2 upon the frame 1 step by step as the lever 3 is depressed. The work holder carries at its upper end a work clamp 8 for securing the work to t-he work support 2, the work clamp not forming any part of the present invention. y,

Associated with the work support is a line 'guide 9, thisv line guide being in this instance in the form of a sheet metal plate secured by rolled portions 10 to a bar 11 which lies horizontally in front of the work supporting plate 2. The bar has at eache` end ,an arm 12, said arms being Apivotally connected at 13 to the stationary frame 1. The bar may be raised and lowered with reference to the plate 2 and at the s'ame time moves toward and `from the plate so as to accommodate work o f.. different thicknesses.

Arranged above the bar 11 and arallel therewith isv a horizontal bar'14 whlchhas at opposite ends, arms' 15 pivotally connected at 13 to the supporting frame 1. "Between the bars 11 and 14 a lens `16 may be arran This lens is preferably in the form o an elongated bar having its rear face plane and its front face convex or cylindrically formed.

This lens bar may be supported yat .opposite ends by clamps, each of which consists in this instancev of a {iat-plate 17. and a curved plate 18 having curved portions 19 at opposite -ends engaging the

bars

11 and 14. Screws 20 secure the

lplates

17 and 18 together and clamp the lens bar 16.y The clamps engage the

bars

11 and 14 in such a manner as to permit the bars to rock in the clamps as the arms 12 and 15l swing. The line guide 9 projects upwardly below the lower edge of' the lens bar and in rear of the latter so that the line-guide is visible through the lens. It is apparent that the supporting means OL 15111811116 guide and the lens not only permits the line guide to be adjusted to the proper position for the eyes of the user of the copy holder, but the lens itself may be so adjusted that -it will correspond to the eyes of the user to give the proper magnification of the work directly above the l1ne guide.

There may also beassociated with the copy holder an illuminating means. This means in this instance is in the form of an elongated lamp 21 which is preferably enclosed within a lampcasing or housing 22 ing and acts to prevent any rays from the lamp fromM issuing below the edge of the line guide.y t

. There may be used in connection with the illuminatingmeans a light ilter preferably in the form of a transparent sheet 24 colored to absorb certain of the rays on the work so that articial daylight is produced. This sheet of material may be surrounded by` a frame 25 which is pivoted at 26 to the lamp 'casing thus permitting the light lter tobe moved to and from a position in front of the lens bar 16.

From the foregoing it will be seen that there has been provided in 'connection with a copy hblder in which the line guide and the lwork support are relatively movable, a

lens for magnifying the work adjacent the line guide, the vlatter -preferably having its guiding edge visible through the lens. The lens is of elongated form and may be moved toward and from the plane of the workso that the lens may be kadapted tothe eye of the user. Also associated with the copy holder is an illuminating means which directs the illumination upon the work adjacent fthe line guide, the line guide preferably forming a continuation of the casing which incloses the illuminating means. There is also provided a light filter which maybe moved to and frorna position where the illuminated work may be visible through the filter, this lter modifying the light rays to roduce artificial daylight.

' ertain features which may be used in any construction in which there is provided v a field to be viewed are not hereinvclaimed broadly but form the subject matter of a. divisional application on reading appliances led by me on June 30, 1921, Serial No,

andenes I What ll claim' as lmy invention and del sire to secure by Letters Patent is:
