holding the members in their proper relative
position. The block 31 is preferably pro-
vided with a short chain 32 for coupling it
to the tail member 25 to prevent its becom-
5 ing displaced and lost when not in use.
Slidably disposed through the openings
in the sides of the casing 12 are two other
relatively long blending plates 33-34 hav-
ing intermediate openings with the edges of
10 the openings serrated as represented respec-
tively at 35-36. The plate 33 is provided
at one end with a vertical slot 37, while the
plate 34 is provided at the opposite end with
a similar vertical slot 38. The terminal of
15 the plate 33 in which the slot 37 is located,
is preferably offset laterally toward the
front of the casing, while the portion of the
plate 34 which contains the slot 38, is like-
wise preferably offset laterally toward the
20 rear of the casing, as represented more
clearly in Fig. 5, the object to be hereafter
explained.
The plates 21-24 are independently slid-
able vertically.within the guideways, while
25 the horizontal blending plates 33-34 are
-likewise . independently slidable transversely
of the casing. By this arrangement also it
will be obvious that by employing cut-off
slides having different sized openings the
30 upper portion of the subject may be cut oft
at any desired point, and then by adjusting
the blending plates, the lower and side por-
tions of the subject may be cut off and the
outlines "blended" through the action of*
35 the serrations in the edges. By this ar-:
rangement also. it will be obvious that by ad-
justing the various cut-off slides and blend-
ing plates any desired portion of the open-
ing through the cut-off slide 15 or 16 which
40 may for the time being be located in the
guideway 14, may be exposed, while the re-
maining portions are obscured, thus con-.
trolling the admission of light and permit-
ting the light to pass through only a por-
45 tion of the casing. By this arrangement
also the opening for the light may be lo-
cated at any desired point opposite. the
opening of the casing. Thus all portions
of the sensitized plate except the portion
50 that it is desired to expose, are covered and
protected, and the exposure located at any
desired point.
By adjusting the various slides and plates
to expose a relatively small portion of the
55 subject and correspondingly focusing the
lens, a correspondingly small image may be
made, or the various slides and plates ad-
justed and the lens focused to produce a
larger image close to a smaller image, and
60 blending the defining lines of the images.
Thus .the pictures can be made large or
small or all of the same size and located at
any point desired upon the sensitized plate.
By this arrangement also a large impres-
65 sion of a subject may be made and then aplurality of small impressions printed
around the larger one and without the
usual " blending " between the pictures.
Any suitable means may be employed for
supporting the casing 12 and its attach- 70
ments from the camera stand, but an ap-
proved arrangement is shown comprising a
head member 40 to which the casing 12 is
attached, and extending from each side of
the head are supporting rails or frame mem- 75
bers 41 suitably braced from the head and
bearing upon opposite sides of the base 11
of the camera and adjustably clamped
thereto as shown at 42. By this means the
casing 12 and its head may be adjusted to go
any suitable extent relative to the lens por-
tion of the camera.
A suitable mechanism whereby the op-
erator can expeditiously actuate the various
blending plates from his position at the 85
rear of the camera forms a part of the im-
proved device, and will now be described.
Connected to the rails 41 are guides 43.
Mounted for rotation through each set of
the guides at each side are two rods 44-15, 90
the rods being formed respectively with lat-
eral offsets or " crank " arms 46-47 for en-
gaging in the slots of the blending plates so
that the rotation of the rods will cause the
reciprocal movement of the plates. The 95
rods are provided at their rear ends with
turn buttons 50 to facilitate their rotation.
The rods may be connected in any desired
order with the plates, but for the purpose
of illustration the rod 44 at one side of the 100
camera is shown connected by its crank arm
46 to the slot of the vertically movable
blending plate 21, while the rod 45 at the
same side of the camera is shown connected
by its arm 47 with the slot of the horizon- 105
tally movable blending plate 33 and the rod
44 at the opposite side of the camera is con-
nected by its arm 46 with the slot of the
vertically movable blending plate 24 while
the rod 45 at the same side of the camera is 110
connected by its arm 47 to the slot of the
horizontally movable blending plate 34.
By this simple means it will be obvious that
the blending plates may be adjusted to any
required extent by simply rotating the rods 115
by the finger and thumb of the operator ap-
plied to the turn buttons at their ends, and
thus adjusting the plates to any required
extent to produce.any required size of open-
ing and at any desired point within the 120
range of the opening in the slide 15 or 16 as
the case may be.
Connected respectively to the rods 44-45
at each side of the camera are two blocks
48-49 and each pair of blocks is provided 125
with a clamp screw 50 extending through
the adjacent rail 41 to enable the blocks to
be clamped upon the rods and thus produce
sufficient ;tension to hold them at any re-
quired point of adjustment, while at the 1302
