This Invention relates to improvements in the construction of frames supports or
bearers for the shafting bushes tie bars or connecting pieces or supports of looms
and other machines and consists in constructing the said supports or bearings (such
for example as the side frames of looms) with contractile sockets (preferably made
in one piece with the frame or support) as hereinafter described.
The said sockets or bearings are rendered elastic by cutting away a portion of
the metal at the side so as to form one or more recesses and are provided on the
opposite side with an opening or openings. Bolts passed through lugs formed on
the sides of this opening or these openings enable the socket to be contracted so as
to grip the shaft tie bar bush or other object inserted in the socket the elasticity of
the metal enabling the socket to expand and relax its hold when the bolt is
unscrewed. By this means the frames of the loom or other machine to which this
CDC21

page_text: Invention is applied are firmly connected and supported and great facility is
afforded for a nice adjustment of the working parts. These contractile sockets may
be advantageously employed for the reception of bushes or wearing rings for shafts
as they admit of the said bushes being readily removed when worn in order to be
replaced by new bushes. Facility is also afforded for altering the width of the
loom or other machine when required by employing the bars and shafting of
suitable length and sliding the side frames upon the said tie bars after loosening
the bolts of the contractile sockets and screwing up the said bolts after the side
frames have been adjusted at the desired distance apart.
And in Order that the said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheet of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 is a side elevation of one of the side frames of a loom having supports
or bearers constructed according to this Invention and figure 2 is a corresponding
end elevation shewing a pair of side frames with the principal shafts and
connections.
Figure 3 is a vertical section taken along the line 1-2 figure 1 and figures 4. 5.
6 and 7 are details hereinafter described.
Figures 8 to 13 illustrate an adjustable support or bearing constructed according
to this Invention.
According to the arrangement illustrated in figures 1 to 7 B B are the side
frames of a loom which are provided at the places where the bosses for the reception-
of the tie bars or other connections are usually situated with contractile sockets D
preferably cast in one with the frames. These sockets are rendered capable of
expansion and contraction by means of an opening or division F on one side of the
socket and a recess or hollow L diametrically opposite to the opening F and
preferably of the shape indicated in the drawing. On each side of the opening F is
formed a lug S through which is passed a bolt T provided with a nut so as to
enable the socket to expand or be contracted by turning the said nut and thus
These sockets may be
loosen the connections or fix the parts rigidly in position
formed either in the body of the frame B or in detachable blocks as in the case of
the support G Figure 1 and the support K Figure 4.
The support G carries a cylindrical tubular bar H by means of contractile sockets
constructed in a similar manner to those in the frames as herein before described.
The openings F in the contractile sockets may be made of sufficient width to admit
of the shafts being taken out laterally from their bearings without impairing the
elasticity of the.socket as shown at P and R figure 1.
In order to enable the width of the loom to be adjusted tie bars E projecting
beyond the side frames may be employed as shewn in figure 2 so as to enable the
'distance between the side frames to be altered when required by loosening the bolts
of the contractile sockets and sliding the frames along the tie bars.
:
This figure also shews the arrangement of the supports G mounted on studs N
contained in or supported by contractile sockets as are also the shaft A and cam
shaft M. The supplementary supports V which connect these shafts together and
render them capable of being adjusted bodily without disturbing their relative
positions are also furnished with contractile sockets which give bearings for the
shafts and connect the support V to the tie bars of the loom
Figure 6 shows a portion of the shaft A supported by the contractile socket P in
combination with a wearing ring or bush C. The socket being accurately bored
enables the bush or ring to be adjusted in position with precision and to be readily
replaced by a new bush when worn out.
Figure 7 illustrates an analogous arrangement for the bearing for the cam
shaft M differing from the arrangement shewn in Figure 6 in having a slot or fork
at the ends of the lugs S in place of a hole for the purpose of facilitating the
removal of the bolt T.
Figure 5 represents the cast iron multiple support V provided with contractile

page_text: sockets J and wearing rings or bushes C whereby it is enabled to be accurately
placed in position without adjusting the shafts separately.
Figure 8 is an elevation, figure 9 is a vertical section taken along the line 3-4
figure 8, and figure 10 a horizontal section taken along the line 5-6 figure 8 of a
plummer block or bearing made universally adjustable by means of contractile
sockets arranged according to this Invention.
Z is a shaft carried in a bearing Y cast or made in one piece with a pivot or
journal C¹ which works in a contractile socket D' similarly made in one piece with
a journal or pivot A' working in a contractile socket B' formed in the frame or
support E¹
Under these conditions the shaft can be adjusted horizontally by
sliding the journals or pivots A¹ longitudinally in the contractile socket B¹ and to
be adjusted vertically by sliding the pivots or journals C¹ in like manner in the
socket D¹ whilst the rotation of these journals or pivots in their respective sockets
also enables the parallelism of the shafts to be obtained the sockets being contracted
by screwing up the bolts T so as to maintain the parts rigidly in position when the
adjustment has been effected. The operation of adjusting is greatly facilitated
by this arrangement and the adjustment is also enabled to be effected with the
greatest nicety.
Figure 11 is a side elevation and figures 12 and 13 are front and back elevations
respectively of an arrangement similar to that illustrated in Figures 8 9. and 10
applied to a support F¹ of different form the shaft being supported in a contractile
socket P' provided with a wearing ring or bush C.
The opening F in the socket P1 is made of sufficient width to admit of the
passage of the shaft sideways when the bolt T has been removed and the ring C
shifted along the shaft so as to clear the socket P¹.
Having now described and particularly ascertained the nature of the said
Invention and the manner in which the same is or may be used or carried into
effect I would observe in conclusion that what I consider to be novel and original
and therefore claim as the Invention to be secured to me is :-
First. In the construction of frames supports or bearers for the shafting bushes
and tie bars or the like of looms and other machines. The employment of
contractile sockets provided with one or more openings and means for contracting
or opening them the said sockets being made in one piece with the frame or
support or bearer substantially as and for the purpose hereinbefore described.
Secondly. The employment in combination with the contractile sockets herein-
before described and claimed of turned wearing rings or bushes nipped or
compressed by the sockets so as to be capable of being changed with facility and
serving as bushes for the reception of the shafts spindles or other analogous parts
substantially as hereinbefore described and illustrated in the accompanying
drawings.
Thirdly, The employment in combination with the sockets herein before described
and claimed of cylindrical journals or pivots and the application of this combi-
nation to plummer blocks and supports for shafting so as to form a moveable
bearing enabling the shaft to be adjusted in all directions with facility and
precision substantially as hereinbefore described and illustrated in the accompanying
drawings.
In witness whereof I the said John Henry Johnson have to this my
complete Specification set my hand and seal this fifth day of May One
