The tubular member 37 is vertically adjustable in the collar 38 for the purpose of elevating and lowering the lamp 34 relative to the reflector 31 and said member 37 is maintained in its adjusted position by a set screw 40 carried by the collar 38. The other end of the arm 39 is provided with a collar 41, through which extends a bar 42, having its upper end, as at 43', fixedly secured to the enlargement The bar 42 is vertically adjustable to permit of elevating and lowering the reflector 31 relative to the lamp 34 and a set screw 43 is provided and which is carried by the collar 41 for the purpose of maintaining the bar 42 in its adjusted position. The bar 42 also provides means for suspending the arm 39. A carrier is provided for the bar 42, and which is in the form of abracket provided with a loop portion 44 through which extends the bar 42 and the latter is detachably secured to the loop portion 44 by a set screw 45. The bracket further includes a pair of oppositely extending inclined arms 46, 47, which are adjustably secured by the hold-fast devices 48 to the legs 1 and 2. Openings 49 are provided in the legs 1, 2 for the purpose of selectively positioning the supporting bracket for the bar 42 and said bracket further provides means for adjusting the reflector 31 and lamp 34 in unison. The bar 42 also provides means for adjusting the reflector 31 and lamp 34 in union, as when the set screw is released and the set screw 43 inbindi-n-g engagement with the bar 42 the latter in connection with.

the arm 39 can be moved upwardly under such conditions adjusting the reflector 31 and lamp 34 in unison.

Secured against the outer face of the back wall 7 at the upper end thereof is a longidicated at 50., Carried b the hinged sect-ion 8 of the top, as well as 'eing pivotally connected therewith is a spring controlled print ing head consisting of a pair of rectangular metallic plates 51, 52 each provided with a resilient lining 58. Secured to the section 8 at the rear thereof is a plate 53, provided with a pair of upstanding apertured ears 54. Mounted in the cars 54, as Well as being con nected thereto, is a spring controlled pivot bolt 55, which carries a forwardly projecting U-shaped member 56 which is secured. as at 57 to the plate 51. The member 56 is pivoted on the bolt 55. The controlling spring for the bolt is indicated at 58 and has one end anchored. to the U-shaped member 56 and its other end anchored to the plate Projecting forwardly from the bolt 55 and onto the outer face of the plate 51 is a pair of links 59 which have their forward end anchored in pairs of short plates 60,61. The plates 61, are secured, as at 63 to the plate 51. Mounted between the plates 60, 61 and projecting across the plate 52, as well as being secured to the latter is a pair of arms 64 which at their rear ends are pivotally connected to the plates 60, 61, as at 65. The means for securing the arms 64 to the plate 52 is indicated at 66. The arms 64 project a substantial distance forwardly with respect to the plate 52. Secured to the front end of the arm 64 is an upset handle member 66 and further arranged between the front ends of the arm 64, as well as being pivotally con nected therewith is a latch member 67 therefore in the form of a bell crank andv which also acts as a means, when the printing head is in operative position, to actuate a switch 68 for closing the light circuit for the lamp 34. The circuit connections are indicated at 69. The latch member co-acts with the front edge 70 of the hinged section 8 of the top for the purpose of securing the printing head in active position to maintain the sensitized surface in position over the plate glass 27 so that when the light source is illuminated the printing operation will be carried out.

The latch member 67 is positionel directly beprinted upon in position with respect to the plate glass 28. After the plates 51 and 52 have been shifted to hold the sensitized surface or paper in position, the latching member 67 is then shifted to securely hold the plate 51 and 52, in the position as shown in Figure 6, and when so shifted will actuate the switch 68, thereby closing the lighting circuit providing for the printing operation.

The reflector and its connections, the lamp and its connections, ground glass, plates or plate glass, hinged section 8, compartment 16 and the printing head and its connections provide a photographically printing mecha nism.

Supported by the cabinet and extending upwardly therefrom, as well as arranged to one side of the printing head, is a combined enlarging, reducing and copying mechanism, and which includes a standard 71 having its lower portion secured by hold-fast devices 72 to the back wall 7 of the body portion of the cabinet. The standard 71 extends a substantial distance above the stationary section 9 of the top of the cabinet and furthermore said standard 71 is centrally disposed with respect to said stationary section 9. That portion of the standard 71, above the section 9 of the top of the cabinet is bifurcated to provide a pair of arms 72, 73 spaced at substantial distance from each other to form a guide passage 74 for a vertically disposed guide bar 75 which projects above the upper ends of the arms 72, 73. Slidably mounted against the arms 72, 73, is a pair of plates 7 6 which are secured to the bar 75 by a bolt 7 6' which projects a substantial distance from the front plate and has connected to its projecting portion an elevating and lowering cable 77. The rear end of the bolt 7 6' carries a securing nut 78. The bolt 7 6 is formed with a pair of squared portions 79 to prevent the turning of the plates 7 6 thereon. The elevating and lowering cable or member 77 is positioned forwardly with respect to the standard 71. Secured to the upperends of the arms 72, 7 3, is a trans versely extending keeper 80 which extends entirely around said arm and between which slides the bar 75 when the latter is elevated and lowered. Projecting forwardly from one end of the keeper 80 and supported therefrom is a pulley 81 over which travels the elevating and lowering cable. The upper end of the cable 77 is provided with a hand grip 82.

Secured to the upper end of the bar 7 5 is a forwardly extending angle-shaped bracket 83, having secured to the front thereof a. lamp-house 84 and positioned therein is an electrical lamp. The socket of the lamp is indicated at 85, and extends rearwardly from j the lamp-house 84 and thecircuit connections I for the lamp are indicated at 86. Any suitable means can be employed for opening and i f closing the circuit to the lamp in the lamp house 84. Secured to the bar 5, Below and in proximity to the bracket 83 is a right angularly disposed and forwardly projecting suspension member 87, which is secured to the upper end of a carrier 88 which is in the form ,and which surrounds the lower end of the lamp-house 84 and upper end of the camera 89. The bellows of the camera 89 is indicated at- 91 and the lens carrying frame at 92, and

the latter is formed with an extension 93, provided with a set screw 94 for detac-hably securing the bellows 91' in adjusted position.

The carrier 88 includes a central bar 95 I formed with a dove-tailed groove 96 forthe reception of the set screw and the latter projects from the bar 95 and carries a securing nut 97 for clamping the set screw in position to maintain the bellows 91 adjusted. The lamp-house 84 is detachably secured to the bracket 83. When the bar 75 is moved upwardly the lamp-house 84, shield 90 or rather light retaining member 90, camera 89 and carrier 88 ar bodily shifted therewith. The stationary section 9, of the top of the housing, provides a support for the sensitized body upon which is printed photographically the enlargement or the reductionof the image or' other object.

Secured at the rear of the stationary section 9,and below the camera or rather directly below the camera is a rule or gauge 99.

for measuring the sensitized paper on which the print is made. A trimming device for the paper is provided at that end of the cabinet opposite the end in which is arranged the printing mechanism, and said. trimming or cuttin mechanism comprises a spring con-.

trolle cutter 100, pivoted as at 101 to the end wall 6 and including at its lower end an exten sion 102, to which a controlling spring 103 is attached. The controlling spring 103 has one end anchored as at 104 to the end wall 6. Normally the cutter 100 is maintained in an elevating position through the action of its spring 103. The cutter 100 cocacts with a cutter 105 carried by the strip 19. c

When copying, a sensitized negative or plate is placed within the camera at the top thereof and the photograph to be copied is positioned upon the stationary section 9, and which permits of a photographic copy to be made of a photograph, by proper adjustment ofthe camera and with the required lenses at 'thelower end of the bellows.

Owing to the adjustability of the camera, that is bodily with respect to the stationary section 9 of the top of the cabinet, and owing to the adjustability of the bellows, enlarging and reducing can be had of different sizes,

that is to say to enable the negative to be enlar ed to any size photograph up to thirty each other, and means for verticallyadjusting inc es or more, or to reduce the negative to said lamp and reflector in unison. a size of three by four inches, and smaller In testimony whereof, I afiix my signature negatives in proportionate size when enlarghereto. 5 ing and reducing.
