, --s Claims. (oi. 240-2) a The present invention relates to. apparatus; for the use of printers in getting their 'forms made ready on press for printing. As isiwell known bythose skilled in the art, when'a'type form is set up and printed from it does not make impressions ofthe same intensity all over the page. Undersuch circumstances, it is necessary to idetermine what parts 'of the impression need strengthening or reducing so that it will be uniform throughout. Thisis ordinarily done by :examiningthe imprint at a. window where the imprint can be 'so placedwith relation to'the window that light coming therethr'ough' will shine across the reverse-side of the paper. Oftentimes, it is inconvenient to carry the printed sheet from the press to the windowland sometimes there is no window available through which sufiicientlight comes to make a success of examining the impression. It is therefore the purpose of my invention to provide means whereby printed sheets may be illuminated'evenly and clearly, notwithstanding the absence of any source of external illumination; to'provide an inexpensive apparatus for the purposeindicated; to provide an apparatus which is more efiicie'nt in operation than what has heretoforebeen-usedfor thepurpose indicated; to provide an apparatus which is more effective irrespective of the illurninationf of the room in "which used; and such'furtherobjects, advantages and capabilities as will hereafter appear and as are inherent'in the construction disclosed herein. My'invention further re- "sides in the combination, construction and a1- rangements of parts illustrated in the accompanying drawing, of the two forms of my invention and I desirethe same tobe'understoodas illustrative only and not to be interpreted in a limiting sense.

In .the'drawing annexed hereto and forming apart hereof, V V I Fig. 1 is a front elevation illustratingone. embodiment of my invention; j Fig. 2'is a transverse section of the structure illustrated in Fig. 1;

Fig. 3 is a transverse section similar to Figi2 invention;

Fig. 4 is a fragmentary sectional elevation illustrating'adjustment mechanism utilized in the structure shown in Fig. 3. v

This construction will now be described in greater detail in connection with the annexed drawing in which the cabinet of my invention is illustrated as being supported upon any suitable top 2.

,structed-entlrely. independently of ,the table, it will of course be understood'that it may be made integral therewith,,taking the. place of the table This device isv illustrated comprising, a bottom 3, aback hatop 5 and ends 6 and 1. The latter are wider ;at the forward ends than-at the back and therefore support the top at an inclination with respect to, the-bottom. In the structure illustrated in Figs. '1, and 2, the bottom 3 is integral and; rigidly connected to the ends 6 and I, while in the construction shownin Fig. 3, ,a portion 8 of the bottom is hinged as indicated at 9 to the other part of the bottom for a purpose to'be set forth more fully hereinaften;

, V A; shelf 10 maybe mounted within the cabinet and above this may be placed a second shelf.- Between thesegshelves is a drawer 12 or a plurality of drawers in which supplies and tools may be kept, if desired, On the under side of theshelf I l0 are mounted any suitable number of lamps l3 which may be .of any design most appropriate for the work involved. Lamps I4 are mounted in the cabinet, either on the under side of thetop 5 or on the ends-S and 1, their purpose being merely to illuminate the interior of the cabinet more completely than can be doneby-the lamps I 3. Suitable switches l5 and I6. control the supply of of illumination-upon the paper l8. On the other hand, much the same effect can be secured with a-lower mounting-ofthe lamps I3 if the bottom or a portionthereofbe hinged asshownin Fig. 3 so that it can be raised as shown by dotted lines. in this figure. However, with such an arrangement it is desirableto provide a pivoted apron l9 but" illustrating a different embodiment of this that'tmsfianbgadmsted miacco'rdance w 1th -table l While the device is shown as being con- I the position of the section 8 of the bottom. Ad-

justability of this apron can be secured in various ways, one of which is illustrated in Fig. 4 in which a shaft 20 is shown as secured to the apron l9 and extending through the end 1 of the cabinet. This shaft is shown as provided with a handle 2| whereby it may be rotated. As illustrated in this figure a socket 22 may be formed in the Wall I for the reception of the spring 23 7 It is believed that it 'front edge to vary the angle the printed sheet.

which places a pressure upon the apron l9 to hold the same in adjusted position. A washer 24 may rigidly or so that it' can be adjusted in position. The location of this reflector is indicated at 25 Y H back, and ends for excluding from a-paper upon and adjusting means is indicatedby the numeral 26. These are not to be understood as illustrating detailed construction but as indicating, rather, the locations of such elements.

While the fixed apron H has been-illustrated in connection with the fixed bottom 3 and the pivoted apron IS in connection with the pivoted bottom section 8, it is desired'that this be understood as merely an' attempt to illustrate these features without implying that these parts are to be used in the particular relationships shown, it being possible to use either type of apron with either type of bottom. Likewise the bottom lll maybe either high or low with either of the forms of the bottom '3. 'Also, the refiector'25, if used, can be used with any combination of the other elements. Furthermore, it is p'rob'able that not so many lights I lwill be used as -indicated in Figure 1 as it is not at all likely that that number will be required to amply illuminate the interior of the cabinet when working therein; -It is of course preferred to cut off the current from the lamps, l4 when relying upon "the illumination from the lamps l3; 1. a V

will be understood from the foregoing that the specific description of structure and method-set forth above maybe departed from without departing from the spirit of my invention as set forth in this specification and the appended claims.
