To all whom it may concern:

Be itknown that we, Amman S. vVrr'rnn and Oman A. GORDON, citizens oil? the United States, and residents of .Vatcrville, in the county of Douglas and State or "Washing ton, have invented certain new and useful improvements in PhotographPrinting Machines, of which the following is a specifition.

Our invention is an improvement in photograph printing machines, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereotl igurc .t is a perspective view of the improvement with a sheet to be printed on the platen; .l -ig. a. similar view, showing the paper contacted with the negative; Fig. :3 is a similar view showing the shutter opened; Fig. lis a similar view showing the shutter closed, and the frame removed front the platen; Fig. 5 is a similar view showing the device in position for removing the negative, and Fig. (3 is a central longitudinal. section.

The embodiment of the invention shown in the drawings, consists of a casing, composed ol. side plates 1, which are extended forwardly near their bot ton; as at 2, and are connected at. their bottom by vertical cross bars'B. of a width equal to the extensions 2. A. horizontal plate t extends between the side plates, esting at its rear end. on the adjacent cross bar, and stopping at its front at the adjacent cross bar as shown in Fig (3. A. second horizontal plate rests upon the tree uppe edgcs oi the side plates, thus forming a casing open at both ends, and a .hase for supporting the same, the base tending foriwrdly beyond the casing. 2. pair of shutters (3, 7, a re provit ed for closing the rear end of the casing, each shutter being provided on one side with a bead in, which is secured a reinforcing rod whose ends are extended as at for engaging bearings in bearing plates, 9 secured to the respective sides of the casing, as at The shutter 6 is hinged to the upper edge of the rear end opening, and the shutter 7 is hinged at the lower edge, the shutters overlapping when closed'as shown in Fig. (3.

It shaft 10 is io nhnaled in. longitudinal slots 10 in the side plates below the plate i, and the ends of the shaft are extended outsidepf the casing, and 'one is provided with a crank arm 11, secured in place by a screw 12, and with a lever 13-, outside of the crank arm and rigid with the shaft. The opposite end is also provided with a crank arm l-l, secured in place by a set screw 15, and a lever 16 pivoted to the casing as at 16, has one of its ends journaled on the shaft inside the crank arm, the lever extending in the opposite direction from the crank arm. Each shutter is provided with a lateral pin 17, and a link 18 having one end journaled on a pin 18 which connects each lever with the other end of the lever 16 as shown at 19 in Fig. 2.

it will be evident from the description that when the shaft 10 is moved laterally by the lever 13, the shutters will be opened wr closed depending upon the direction of movement of the lever. iVhen the shaft is moved forward from the position shown in Fig. 2 it is moved to the rear they will be closed. An arm 20 is pivoted to the outer face of each extension as at 21, and the upper ends of the arms are connected by a rod 22. A link 23 connects one of the arms with the crank arm 11., and a similar link 24: connects the other arm with the crank arm 14, the links being pivoted to the respective arms as at 25. A platen 2G is provided at each end with a bearing 27, which is journaled on the rod and a bracket 28 is secured to the outer face of the platen near the lower edge, the bracket having parallel spaced lateral lugs between which is pivoted one end of a link 29, the other end being journaled on a rod 30 extending between the extensions 2.

it will be evident from the description that when the shaft 10 is oscillated to open the shutters, the platen will he swung from vertical position shown in Fig. 2, the platen being constrained to take such positions by the link mechanism just described' A printing frame 31 substantially rectangular in form is arranged at the front end of the casing, the internal cross-section of the frame, correspomling to that of the casing. The lower end of the frame upon the upper faces of the extensions 2 and the front the shutters will be opened, and when l the inclined position shown in. Fig. 1 to the bar 3, and the upper edge of the frame provided with a pin 32, ,for engaging a catch 33 secured to the casing as at 3 The lower edge of the frame is provided with openings 35, which receive pins 36 on extensions, and the pins and the catch lock the frame in position against the end of the casing. The inner surface of the frame is provided with an annular rih 37 gainst which'rests the edges of a transparent plate 38, of glass or other suitable mate The negative 39 is superimposed on rial. the plate 38, and is arranged between upper and lower bars 40, which are recessed longia tudinally at their centers as at 4-1 for receiving; the edge of the negative, and are provided their ends with longitudinal slots it-2. The slots are engaged by threaded stems 43, which are provided with heads {not shown) slidable in undercut slots 44: in the frame, and arranged at right angles to the slots 42. The bars are retained in place by nuts 45, and it will be evident, that by loosening the nuts the bars may be adjusted toward and from each. other and transversely of the casing, to provide for negatives of different sizes. lhe bars are provided with spaced lugs 46 on their adjacent edges, which engage the outerface of the negative to retain it in contact with the glass. The platen 26 is provided with a dity of pins tive, which are arranged in angular reon, and act as stops for supporting the ting paper-48 in proper position in west of the negative. That part of the platen upon which the print rests is pro- "l d with a layer of felt. as shown at 4-9 1, 4, A plate 50 is journaled on the aft in the center of same within the a 10. The plate is slidahle on the end rod whose other end is secured in "trout. har 3 and a coiled spring ircles the rod between the plate and a threaded into the rod. After lever -aoved to the platen, a fur- "nt 13.11% will tend to in the slotted is, thus compress and pro for a yielding the paper against the ucga e and the same time causopen, the movement 7 v p 1 H naten to yield outwardly, w nd a spring ion) or the y .Ji tl: new jive is in place :1 the end of the link t nori'nallv ret t the pivot pin at the outer end of the slot. one end of the spring hens; conitiected t the platen. as at 55, and the other being;

LL as at s for receiving the lugs 'thcreil-7 on the face adjacent the p t which gournal-ed on the L :0 I h 28 are slotted as er to permit the hob In operation, the parts being in the position shown in" Fig. l'with the frame removed, one of the bars 410 is loosened, a negative inserted, and the bar again secured in position. The lower edge of the frame is engaged with the pins, and the upper edge is pushed against the end of the casing, thus engaging the catch with the pin. of printing paper is laidon the platen, with its edges against the gage pins, and the lever 13 is moved downward. This movement oscillates the shaft 10, and the platen is moved against the end of the casing. As soon as the platen-engages the end of the casing, the shaft moves forward in the slots and the lever 16 is swung to open the shut-' ters. After an exposure of proper time, the movement of the lever is reversed, which closes the shutters and moves the platen to horizontal position. It will be understood that the light enters the rear end of the casing the said end being turned toward the li ht.

it will be evident from the description that the machine is simple and cheap in construction, and being free from complicated parts is not liable to easily get out of order. It is also portable being small and compact.

The gage pins l7 extend through openings in the platen, and are secured at their outer ends, in any suitable manner to the free ends of plate springs L7 whose other end is secured to the rear face of the platen.

This construction permits the pins to yield inwardly level with the face of the platen, when the print is formed in contact with the negative.

It will he observedthat alter the print has been exposed, and the platen is moved away from the negative by the handle 13,

the platen may be turned past the position shown in Fig, 1, and into the position shown in Fig.4, and the print will slip off the platen, being thus automatically discharg d from the inachine. It will be evident that the machine may he usec with either natural or artificial lig, it, and that it isvery speedy in its operation.
