vided with a transparent plate for the nega-
tive to rest against, a platen mounted to
swing toward and from the said plate and
adapted to carry the printing paper, into
5 contact with the negative, and a clamping
device for clamping the negative in place
on the said plate, the clamping device hay-
* ing a handled extension for controlling the
clamping device and for forming a bottom
10 rest for the lower edge of the printing paper
to rest on while being carried to the nega-
tive.
2. A photographic printing machine, pro-
vided with a transparent plate for the nega-
15 tive to rest against, a platen mounted to
swing toward and from the said plate, and
adapted to carry the printing paper into
contact with the negative, a clamping device
for clamping the negative in place on the
20 said plate, the clamping device having a
handled extension for controlling the clamp-
ing device and for forming a bottom rest
foxy the lower edge of the printing paper to
rest on while being carried to the negative,
25 and manually-controlled means for adjust-
ing the tension of the said clamping device.
. 3. A photographic printing machine, com-
prising a casing having a door at its front,
a frame hinged in the rear of the casing and
30 carrying a transparent plate for the nega-
tive to rest on, a platen hinged on the said
frame and adapted to carry the printing
paper into printing contact with the neea-
live, a clamping device for removably hold-
35 ing the negative in position on the said
platen, and a spring-pressed gage mounted
en the said platen at one side thereof for one
side of the printing paper to abut against.
4. A photographic printing machine, coin-
40 prising a casing having a door, at its front,
a frame hinged in the rear of the casing and
carrying a transparent plate for the nega-
tive to rest on, a platen hinged on the said
frame and adapted to carry the printing
45 paper into contact with the negative, and
a clamping device for removably holding
the negative in position on the said plate,
the said clamping device having a handled
extension passing through the platen and
50 forming. a rest for the lower edge of the
printing paper.
5. A photographic printing machine, coin-
prising a easing having a door at its front,
a frame hinged in the rear of the casing
55 and carrying a transparent plate for the.
negative to rest on, a platen hinged on the
said frame and adapted to carry the print-
ing, paper into printing contact with the*
negative, a clamping device for removably
60 holding the negative in position on the said
plate; a mat vertically slidable on the said
frame in front of the said transparent plate
and normally in a lowermost position, and
means for holding the mat in an uppermost
65 position,6 A photographic printing machinecom-
prising a casing having a door at its front,
a frame hinged in the rear of the casing and
carrying a transparent plate for the nega-
tive to rest on, an apertured platen hinged 70
on the said frame and adapted to carry the
printing paper into printing contact with
the negative, a clamping device for remov-
ably holding the negative in position on the
said plate,.said clamping device being pro- 75
vided with a member projecting through the
aperture. of the platen, and a bail-shaped
stop on the said frame for the said platen
to rest on in open position.
7. A photographic printing machine, com- 80
prising a casing having a door at its front,
a frame hinged in the rear of the casing
and carrying a transparent plate for the
negative to rest on, a platen hinged on the
said frame and adapted to carry the print- 85
ing paper into printing contact with the
negative, a clamping device for removably
holding the negative in position on the said
plate, -butter rollers journaled in the upper
and lower portions of the casing interme- 90
diate the said door and frame, belts connect-
ing the rollers with each other, shutters
winding, and unwinding on the said rollers
and attached to the said belts, a manually-
controlled slide mounted on the casing, a 95
flexible connection between the said slide
and one of the rollers for turning the same,
and a spring device connected with one of
the rollers for normally holding the shut-
ters in closed position. - 100
. 8. In a photographic printing machine, a
casing, a support carrying a transparent
plate for the negative to rest on, an aper-
tured platen for carrying the printing paper,
and a combined rest and clamping plate for 105
supporting the printing paper and clamp-
ing the negative on the transparent plate,
said rest and clamping plate having a mem-
ber projecting through the aperture of the
platen and forming a handle. 110
9.. In a photographic printing machine, a
casing, a frame carrying a transparent plate
for the negative to rest on, a hinged platen
carrying the printing paper, and provided
with an aperture, a clamping plate having 115
its upper end curved outwardly and extend-
ing through the aperture of the platen, and
screws carried by the frame and. engaging
the said plate for .adjusting the same.
10. In a photographic. printing machine, a 120
casing, a hinged frame carrying a transpar-
ent plate for the negative to rest on, a platen
hinged to the frame for carrying the print-
ing paper, a clamping device for clamping
the negative on the transparent plate, and 125
a loop-shaped member carried by the frame
and forming a stop ior the platen.
11. In a photograph ic printing machine, a
casing, a frame hinged. in the rear of the eas-
ing for carrying a transparent late for 130
