COMPLETE SPECIFICATION.
Improvements relating to Printing Presses.
I, HERBERT JOHN HADDAN, of the Firm of Herbert Haddan & Co., of 18,
Buckingham Street, Strand, W.C., London, Consulting Engineer, do hereby
declare the nature of this invention, a communication to me from abroad by The
Babcock Printing Press Manufacturing Company, of 38, Park Row, in the City
5 of New York, United States of America, Manufacturers, and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-
By means of this invention a printing press or the like can be supplied with
so-called slip sheets or smut sheets so that such slip sheets are in convenient
reach or position as required for being placed on top of a printed sheet before
the next succeeding printed sheet is laid on the printed pile. The invention is
set forth in the following specification and claim and illustrated in the annexed
drawing in which-
Figure 1 is a sectional side elevation of a carrier.
Figure 2 is a side elevation showing the tape carriage in different position
than in Fig. 1.
Figure 3 is a plan view of Fig. 2.
Figure 4 shows a modification.
The tape carriage E is well known and need not be described in detail as it
can be actuated or reciprocated by well known means.
A slip sheet table is shown at G, applicable for example to such a recipro-
cating part as the slides (G) at delivery board (E) shewn in Fig. 1 of British
Patent 7364 of 1897, the slip sheets H being piled onto this board or table G.
This board G is carried by or provided with rods or supports I which can be
extended entirely across under the table G or secured only to edge parts thereof
and provided with end or hook portions K made to engage or straddle the axles
of the tape carriage wheels 1 and 2. Six such hooks K have been found to form
a practical support for board G, four such hooks being at the sides or near the
vheels, and two in the centre line of the axles or approximately so.
As the tape carriage runs to the receiving board or table the slip sheet table
r,pile moving with the carriage brings the slip sheets into reach of the atten-
ant at the receiving table. Such attendant lifting or flipping the top slip sheet
pose from pile H and holding it to or over the printed sheet just delivered,
ach slip sheet on the return of the carriage will drop or come to rest on such
op sheet of the printed pile.
A back stop. M has been found useful for aligning the slip sheets or keeping the
ip sheet pile in proper place.
Of course the slip sheet table G need not be mounted on a tape carriage but
ch slip sheet table could be otherwise applied or independently mounted and
ciprocated. The construction shown however is simple and has been found
viceable in practice. As shown in the drawing this slip sheet table is applied
a so-called front delivery press.
In addition to back board M the table G might have sides or lateral
[Price 8d.1

stop could also be applied in which case the slip sheets successively lifted off the
pile would have to be drawn over this front stop. In practice however a front
stop has not been found necessary.
In Fig. 4 the hook fastenings I are shown replaced by rods I. Three such
rods can be applied, one at the centre and two at the sides of the table G. Each
rod having its ends hooked and such hooks K rising somewhat from rods I', the
board G could be loosely laid on such rods and would be prevented by the hooks
or riser K from slipping or shifting backward or forward.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a printing press, the combination with delivery mechanism for the
printed sheets of a reciprocating slip sheet carrier supporting the pile of sheets,
substantially as described.
2. In a printing press, the combination with delivery mechanism for the
printed sheets, of a reciprocating slip sheet carrier, supporting the pile of sheets,
actuated by said delivery mechanism substantially as described.
3. In a printing press, the combination with a tape carriage, of a bodily
movable slip sheet carrier, supporting the pile of sheets, mounted on said carriage
and operated thereby, substantially as described.
4. In a printing press, the combination with a tape carriage, of a bodily
movable slip sheet carrier, supporting the pile of sheets, mounted on said car-
riage and operated thereby, and a back stop for the sheets on said carrier, sub-
stantially as described.
5. A printing press having a tape carriage and a slip sheet table or carrier
having rods or supports provided with hook portions made to engage the axles
of the tape carriage wheels substantially as described.
6. A printing press having a tape carriage and a slip sheet table or carrier
having rods or supports provided with hook portions made to engage the axles
of the tape carriage wheels, said hook portions being made to rise above the table
or board of the slip sheet carrier to prevent the bottom sheet sliding substan-
tially as described.
