means of a connection permitting the drum tobe

35 form of connection herein shown comprises a
V sleeve 39 (Fig. 3) slidable lengthwise of the shaft
38, but having a key 40 ?tting in a keyway 4| in
the shaft. The winding drum is rotatably mount
‘ed on the sleeve 39 and is yieldingly connected
40 thereto by means of a coiled torsion spring 42,
one end of the spring being fastened to the wind
ing drum and the other being attached to a ?ange
43 on the'sleeve. The spring'tends to turn the
drum in the direction to wind up the tape. To
> 45 hold the sleeve in the position to which it has
been adjusted along the shaft, I'provide a collar
44 surrounding the sleeve 39 and having a periph
eral groove 45. Approximately one-half of the
bottom of the groove is cut away to accommodate
50 a semicircular brake shoe 46 that lies in a semi
circular recess 46a in the sleeve 39. A contractile
spring 47 lying in the groove 45 presses the brake
shoe against the shaft 38. The shoe is of suffi
cient radial thickness to extend into the groove
55 45 (see Fig. 3) and thus serves to hold the collar
44 against endwise movement on the sleeve 39.
.The winding drum is held between the~ ?ange 43
and the collar 44.

The shaft 38 is rotatably mounted in a rigid
60 frame 48 consisting of two arms 49 and a tie rod

The arms 49 are pivoted to the end plates
2 and 3 at 5|.
Rubber-covered rolls 52 are
its ends the band 6| extends over a roll 63 which -
is rigid with the left-hand end of the rubber
covered roll 53. The course of the band 6| is
best shown in Fig. 8. When the ?nger wheel 59 is
turned to draw the tapes 33 downwardly, the
rubber-covered roll 53 is rotated in the same .
direction through the action of the tapes in turn
ing the shaft 38 in the direction to wind up the
band 6| on the roll 62, the friction of said band
on the roll 63 causing the roll 53 to turn. When
the ?nger wheel 59 is turned in the opposite 40
direction, the band 6| is wound up on the roll 3| ,
whereby the roll 53 is rotated in the direction to
feed the ledger sheet upwardly, and the shaft 38
is rotated in the direction to ‘wind up the tapes
on the drums 31. The spring connection between
the drums and the shaft 38 compensates for vari
ations in the thickness of the windings on said
drums as the tapes are wound up and unwound.

roll 3| and hence the roll 53 in either direction. a

an intermediate gear wheel 66 which is rotatably
mounted on the end plate 2 and which in turn
meshes with a pinion 61 which is arranged to be
connected to the shaft of the roll 3| by means of
a clutch 68. When the pinion 61 is clutched to the
shaft of the roll 3 |, a forward pull upon the han 60

The roll 53 is slightly larger in diameter than
the roll 63, hence the peripheral speed of the roll 70
53 is slightly greater than the speed of the tapes.
Consequently, if the operator does not insert the

edge being. in .contact with only one of the
steps 58) the rotationef the roll 53 will cause

the statement sheet will be inserted in front of pendently line-spacing sheets introduced by both

such that when the injector 65 is operated, the

‘The distance between the bottom edge of the
15 ledger sheet and the line to be printed upon will
usually be di?erent from the distance between
the bottom edge of the statement sheet and the
line to be printed on. It will therefore be under
stood that said sheets will ordinarily be inserted
20 di?erent distances, only one of the sheets being
inserted into engagement with the stops 58.
It will .be seen that the construction herein
' shown facilitates the insertion 'of the ledger sheet
in upright position in front of the platen with the
25 face of the ledger sheet toward the operator, and
that this result is attained without movement
of the platen out of operative position. Since
the platen is not movable transversely of its
axis, it is described in some 'of the following
30 claims as being mounted on a ?xed axis.
