and Parts of Carding Engines and other Machinery.
We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth
Brothers of the Moss Brook Works, Collyhurst, Manchester, in the County of
Lancaster, Engineers, do hereby declare the nature of this Invention to be as
follows:
Our said Invention is applicable primarily to the adjustment and levelling of the
side frames of Carding engines, but may also be employed to adjust and level the
frames and heavy parts of other machinery in setting which very careful and fine
adjustments are desirable or necessary. In fitting up a carding engine and especially
when putting together our improved carding engines having turned bends, it is necessary
that the side frames should coincide in their relative positions exactly with the carding
cylinder and other parts, and that they should be exactly level so as to secure the
proper working of the flats. Hitherto in moving and canting the frames into the desired
positions, wedges, crowbars, and other temporary means have been employed, with the
result that an extremely fine adjustment has been difficult to obtain. According to our
invention we provide a jack of a particular construction and consisting of a flat metal
plate recessed to contain an anti-friction bowl or sphere or anti-friction bowls or spheres
which projects or project slightly above the level of the plate. The said jack-plate is
provided at each end with set screws having thumb, capstan or other heads to facilitate
their being turned. When in use the plates are put beneath the frame or frames and
between the feet the conical ends of the set screws preferably bearing upon smaller

page_text: countersunk plates laid directly on the floor. By turning the screws the frame can
be raised entirely from the floor and as it then rests on the anti-friction bowls of the
jack plate, it can be easily moved in one direction or the other and adjusted longi-
tudinally or perpendicularly and packed to the required height and level. Under a
modification the aforesaid set screws may be employed to slide wedges which would
raise and lower the frame in the same manner as the screws or-the said wedges might
be operated by other means. It will also be evident that cams might be employed for
the same purpose as the screws or wedges.

We GEORGE ASHWORTH and ELIJAH ASHWORTH of the firm of Ashworth Brothers
of the Moss Brook Works, Collyhurst, Manchester in the County of Lancaster
Engineers 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 and accompanying drawings:
:-
Our said Invention is applicable primarily to the adjustment and levelling of the
side frames of carding engines but may also be employed to adjust and level the
frames and heavy parts of other machinery in setting which very careful and fine
adjustments are desirable or necessary. In fitting up a carding engine and especially
when putting together our improved carding engines having turned bends it
is necessary that the side frames should coincide in their relative positions exactly
with the carding cylinder and other parts and that they should be exactly level so as
to secure the proper working of the flats. Hitherto in moving and canting the
frames into the desired positions, wedges, crowbars and other temporary means have
been employed with the result that an extremely fine adjustment has been difficult to
obtain. According to our invention we provide a jack of a particular construction
whereby the adjustment of heavy parts is more readily and correctly effected than by
the aforesaid means.
And in order that our said Invention may be properly understood we will now
proceed more particularly to describe and ascertain the same, reference being had to
the annexed sheet of drawings and to the letters and figures marked thereon.
Fig. 1 is a side elevation of our improved dwarf jack.
Fig. 2 is a plan of the same.
The body of the jack consists of a rectangular metal plate a which is recessed as
shown to contain an antifriction bowl b carried on a pin or stud c and projecting
somewhat above the level of the plate a as seen in Fig. 1. The recess a¹ in the
plate a is open at the end to permit of the introduction of the stud c or if closed at
the end it must be made of sufficient length to allow the stud c to be entered or placed
in position. We might however slot the sides of the recess containing the bowl b and
drop the stud and bowl into position. The plate a is furnished with three supporting
and adjusting screws d, d¹, d², having conical points which rest in countersunk
recesses in the floor plates ef as shown at Fig. 1. In some instances these floor
plates e. fmight be dispensed with. The heads of the screws are furnished with
bars or with wings or polygonal or capstan heads or other means to facilitate the
screws being turned. Two of the screws d, and d¹ are situated at one end of the plate
and the third screw at the opposite end as clearly seen in the plan view Fig. 2.
When the jack is in use it is placed beneath the frame and between the feet the frame

page_text: resting on the antifriction bowl, b. By turning the screws the frame can be raised or
lowered or canted either in a sidelong or in a longitudinal direction. If it should
be necessary to move the frame either backward or forward in the direction of its
length, the anti friction bowl upon which the frame rests would render such moving
comparatively easy. When the exact position of the frame has been thus accurately
determined the feet are packed to the adjusted level and the frame secured to the
foundation or floor by the ordinary or suitable means. It will be understood
that one, two or a greater number of dwarf jacks of the indicated construction
may be used in adjusting and levelling a frame or other portion of a machine or
structure.
Figs. 3 and 4 indicate modifications which might be made in the construction of
the jack and illustrate the employment of means other than the aforesaid adjusting
screws to raise and lower the plate a. For example in Fig. 3 the plate a is supported
on cams carried on spindles or studs in the floor plate j. The cams may be
turned by a key or wrench fitting on the squared ends of the cam axles and to support
the cams in their adjusted positions a ratchet and pawl arrangement may be used as
shown at k. l. Fig. 3.
In Fig. 4 the plate a rests on inclined blocks or wedges m which slide on the floor
plate n and are capable of being moved in one direction or the other by means of
adjusting screws o the screws being turned by a key, or a wrench or by other suitable
means. The plate a and superimposed frame or object can thus be raised or lowered
or canted by advancing or withdrawing the wedges in accordance with the
required result. Two three or a greater number of the herein before described cams
or wedges may be used. The top member in a pair of folding wedges might carry a
roller as indicated in Fig. 5 and be used for the same purposes as our invention but
would not be so effective for the reason that in the raising and lowering adjustment
the roller would slide in contact with the object being adjusted or otherwise would
move such object horizontally, and we therefore prefer such formations as are indicated
in Figs. 1 to 4.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is:-
-
(1) The general arrangement and combination of parts composing an apparatus or
jack for levelling and adjusting the frames of carding engines and other machines or
parts of machinery substantially as described and illustrated.
(2) In a levelling and adjusting apparatus or jack of the indicated nature the
combination of the plate a antifriction roller band adjusting screws d, d', d²,
substantially as described and illustrated.
(3) In a levelling and adjusting apparatus of the indicated nature, the combination
of a roller with adjusting cams or sliding inclined blocks or wedges operated and
acting for the purposes and substantially in the manner described and indicated.
