PROVISIONAL SPECIFICATION.
Improvements in Printing Presses.
We JOHN JORDAN of 17 White Lion Street Pentonville in the County of Mid-
dlesex, Stamp Maker, and EBENEZER HOWARD of 17 Cliffords Inn, in the same
County Shorthand Writer do hereby declare the nature of this invention to be as
follows:-
The object of this Invention is the production of a Jobbing Printing Press of
extremely simple construction, of great strength and of large inking power combined
with uniform distribution.
The frame-work of the press consists of two uprights which for the purposes of
strength may be united at their bases.
Cast with or otherwise secured to one of the uprights is a type-bed--the surface
of which is preferably in a vertical plane-having cheeks to form a support for similar
inking cylinder to that described in Specification No. 11585 of 1887.
A main shaft supported by the uprights above referred to passes through the said
cheeks. Two arms or roller-gates, one of which is fixed rigidly to or forms part
of the main shaft-the other arm being a strap-head capable of revolving freely in
a channel formed in an extension of one of the aforesaid cheeks are connected
together by means of rods or bars. The chase is secured to the type-bed in any
convenient manner.
The platen may be brought to the type by any well-known device.
Dated this Twenty-fourth day of June 1889.
COMPLETE SPECIFICATION.
Improvements in Printing Presses.
We, JOHN JORDAN, of 17 White Lion Street Pentonville, in the County of Mid-
dlesex, Stamp Maker, and EBENEZER HOWARD, of 17 Cliffords Inn, in the same
County, Shorthand Writer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :--
The object of this Invention is the production of a Jobbing Printing Press of
extremely simple construction, of great strength and of large inking power combined
with uniform distribution.
In order that our Invention may be the better understood, we have appended the
accompanying two sheets of drawings, in which Fig. 1 is a transverse section (on the
line A. B. figure 2). Figure 2 is a plan view. Figure 3 is a side elevation-at
the time of impression. Figure 4 is a front elevation. Figure 5 is a side elevation,
showing rollers inking the type and platen in position for laying on. Figure 6 is a
detailed view of roller arm intended to turn in groove shown in Figures 7 and 9.
Figure 7 is a rear elevation of the bed-plate and uprights showing groove in which
roller arm (see Figure 6) is intended to turn-the dotted lines showing_position of
main shaft. Figure 8 is a side elevation and Figure 9 is a plan view. Figure 10 is
a detail showing inking table and carriage on which the same may oscillate, with
shuttle and grooved cam.
The frame-work K (see figure 7) of the press consists of two uprights which for
the purpose of strength may be united at their bases. Cast with, or secured to one
of the uprights is the type-bed S., the surface of which is preferably in a vertical
plane, having cheeks Q figures 7 8 & 9 to form a support for inking surface, which

page_text: inking surface may be similar to that described in Specification No. 11585 of 1887.
The main shaft supported by the uprights above referred to passes through the said
cheeks. Two arms or roller gates-one of which, E, is fixed rigidly to or forms part
of the main shaft-the other arm, E2, (shown in detail in fig. 6) being a strap head
capable of revolving freely in a channel or groove R formed in an extension of one
of the aforesaid cheeks-are connected together by means of rods or bars E¹.
The platen may be brought to the type by any well-known device. The method
illustrated in the drawings is substantially known, but may be described as follows.
Shaft B is caused to revolve by power or by treadle attached to rod B² (see fig. 5).
Spur wheel B secured to shaft B' engages with wheel A which is keyed to the
main shaft A' (see fig. 2). To the other end of the main shaft is secured disc A².
Rods G connect wheel Á & disc A³ with the platen G as shown in figures 3 & 5–
the platen being pivoted on shaft B' or other suitable shaft.
Hare the friskets turning on shaft H operating in a well-known manner.
G² are adjusting screws.
The mans
The chase may be held in position in any well-known manner.
illustrated in the drawings are top & bottom pieces L' & 12, see figures 1 and 2.
Side pieces W, figures 7, 8 & 9, hold the chase laterally & serve as ways for the
runners F of inking rollers D.
The method of ink distribution illustrated is very similar to that described in our
Specification No. 11585 of 1887. C¹ & C², figures 1 & 10, are the grooved cam &
shuttle & C is the inking table with its ribs or stays n, figures 1, 3, 5 and 10, all of
which parts were fully described in that Specification. An improvement, however,
is exhibited in the manner of supporting the table. M (see fig. 10) is one of two
supports for inking table which are secured to checks by screws S, figure 10,
passing into holes T shown on figure 7. The ink table is caused by the action
described in our said Specification-to oscillate on the rods m¹. It will be apparent,
however, that other forms of inking surface might be employed-the form illustrated
being simply that which we prefer.
The details shown in figure 6 need but little description. D are the inking rollers,
Frunners and O springs attached to holders N, serving to keep the rollers down to
their work.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed we declare that what
we claim is
First. The improved printing press or machine substantially as herein set forth and
shown in the accompanying drawings.
Second The combination of type-bed S, cast with or secured to frame K main
shaft A with roller arm E secured to such shaft and with roller arm E2 turning in
groove R substantially as described and illustrated in the drawings.
Third. In a printing press or machine the combination of cheeks Q supports M
& rods M' forming a way on which the ink table may oscillate with roller arm E
secured to, main shaft & roller arm E2 turning in groove R, substantially as described
and illustrated in the drawings..
