Improvements in Printers' Chases.
I, PAUL HURTHEв of Pittsburg in the County of Allegheny and State of
Pennsylvania United States of America, Manufacturer, 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:—
This invention relates to printers chases as hereinafter particularly described.
Figure 1 of the accompanying drawing represents the chase when ready for the
press F being the form of Type, the parts marked K being the wide stacks those
marked Q the quoines, those marked S being the superficial transverse slots, and
those designated by I being the intersections of the 'bars.
The part for which letters patent is hereby sought is the chase or frame, con-
sisting of the four bars marked B.-Figure 1 and the sliding lock as shown in
figures 3. 4 and 5.
These bars are exact duplicates of each other, a description is as follows:-
It consists of a simple bar of steel or other suitable material with a rectangular
section and of dimensions varying with the size and strength that may be required
the bar has a number of superficial slots or notches (see Figure 2) entering through
the entire width of the bar, but only through half its thickness, and of such width as
to receive another bar, whereby they intersect in a close fitting dovetail.
Along the middle of the sides of the bar are longitudinal slots or grooves which
extend the whole length of the bar, the purposes of these slots is to provide a means
for holding the bars firmly together at their intersections, and their office will be
made fully apparent from a description of the sliding locks and from the drawings of
the same; in figures 3, 4 and 3 it must be understood however, that no great
strength is required in those locks because the pressure of the form when locked in
the chase is amply sufficient to keep the frame from coming apart, their purpose is
rather to hold the chase together so that it may be moved or handled without taking
apart, while at the same time it may act as a guard when the form is confined in the
chase.
The sliding lock is made of spring steel so fashioned as to slide along the side of
the bar containing the slots and so bent as to work along the slots or grooves G. G.
This device is provided with a projecting piece P which overlaps the point of
intersection of the bars, and also with two other projecting pieces or parts TT
which fit into the corresponding slits of the cross bar thus holding or locking the
bars firmly together.
The part marked M is allowed to project in the other direction along the upper
surface of the bar and is so bent or shaped as to operate as a spring thus keeping
the lock in the desired position.
The value and utility of this invention may be summed up as follows:-
They may do away with all necessity for any furniture; but side sticks and thereby
save time and trouble, securing at the same time a firmer lock-up.
By reason of their adjustability to all sizes of forms a few chases will serve the
printer where many of the solid and rigid ones now in use are now required and thus
save great and unnecessary expense.
The chase always fits the bed of the press for which it is intended no matter what
may be the size of the form, thus securing the most rapid lock-up possible and doing
away with the filling out furniture heretofore required to adjust it.
As one chase answers the purpose of many by reason of its adjustability no time is
lost to the printer in exchanging one chase for another.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
First. A printers chase, composed of four similar intersecting bars, each provided
with two or more superficial notches, substantially as described.
Secondly. The combination with a printers chase, composed of four interlocking
bars, provided with two or more superficial notches, of sliding clamps, which embrace
the bars at their intersection, substantially as described.
Dated this 17th day of June 1889.
