Improvements in Floor and Ceiling Plates.
A communication from THE BEATON & BRADLEY COMPANY, of Southington,
Connecticut, United States of America.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, 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 improvements in floor and ceiling plates or collars for
pipes and the objects of the improvement are simplicity and economy in construction
and general convenience and utility of the article.
In the accompanying drawing-
Figure 1 is a plan view of the plate or collar.
Figure 2 is a reverse plan view of the same.
Figure 3 is a perspective view of the plate or collar showing the under side, the
two parts being slightly separated from each other.
Figure 4 is a sectional view on the line of Fig. 2.
Figure 5 is a detached sectional view of a portion of one plate on a concentric
curved line just outside of the spring latch 9, and-
1
Figure 6 is a sectional view of a portion of the same on the line y y of Fig. 4.
The plate has two principal parts A. B. made preferably of cast metal and
divided diametrically as shown. The outer or finishing flange or rim 5 of
these parts may be of any pleasing or ordinary design. The inner or collar
flange 6 may be fitted to the pipe but it is preferred to make it on a curve
a little larger than the pipe for which it is intended and provide its inner
surface with ribs 7 which may be made of greater length than the width of said
flange as shown in Fig. 3, and 4. These ribs are for engaging the circumference
of the pipe to form a bearing to assist in centering the complete device and holding
it in place. It is also preferred to employ the spring arms 8 to furnish additional
bearings on the pipe and to insure sufficient friction to hold the complete device
in position thereon., Said spring is secured by forming or sawing slits in the collar
flanges 6 then forcing an offset portion of the flat sheet metal spring edgewise into
said slits and if necessary heading down the metal at the mouth of the slits to
prevent the springs from working out of the slits. The same piece of sheet metal
that forms the spring arm 8 on the part B is extended outside (i.e. on to the larger
circumference) of the collar flange and made narrow at its outer end to form a
spring latch 9 and it is limited in its outward movement by a suitable stop 10 on
said part B.
The part A is provided with two hooked lugs 12 and 13. Both of these lugs
have the points of their boods turned towards the central opening of the device so
that a recess is formed between the inner face of the point of each hook and the
shank which connects it with said part A while the lug 12 has a beveled or sloping
face 14 to resist a movement of one part on the other in the longitudinal direction
of the pipe. The lug 13 is provided with an abrupt shoulder 15 for the same
purpose. The hollow or recess between the flanges 5 and 6 on the part B will
admit the body of the lugs 12 and 13, while the outer edge of the flange 6 in the
longitudinal direction of the pipe is provided with a radially projecting web 16 for

page_text: engaging said hooked lugs and preventing the parts A. B. from moving away from
each other in the plane which is common to them when they are joined. The end
edge of the flange 6 on the part B at the point in front of the face 14 is made
overhanging as at 17 to prevent that side of the parts A. B. from moving in
the longitudinal direction of the pipe while the spring latch 9 at the other side
engages the shouldered lug 13 for the same purpose.
After the parts A. B. are thus constructed they may be brought together from
opposite sides of the pipe and then tipping them slightly into different planes the
lug 12 of the part A is placed in engagement with the web 16 and overhanging
edge 17 of the part B. Then pressing them toward the pipe and swinging on
the lug 12 as an axis to bring both parts into the same plane, the nose of the lug 13
will engage the spring latch 9 to push it out of the way as the other radial web 16
is brought into engagement with the recess of said lug. As soon as the greatest
projection of the lug 13 passes the spring latch 9 said latch springs out over said
shouldered lug and secures that side of the parts together whereby they are securely
held against being separated by a movement either in a radial or longitudinal
direction. The spring arms 8 and ribs 7 now bear upon the pipe with sufficient
friction to hold the plate or collar in the desired position on the pipe. In order to
remove the plate or collar the spring latch may be pushed from in front of the
shouldered lug 13, then move the parts reversely to the movements described for
putting them in place.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondents, and in what manner the
same is to be performed, I declare that what I claim is ;
1. A pipe thimble consisting of two sections joined at their abutting ends by
hooked lugs and recesses with which the sections are respectively provided, one end
of one of the sections having an overhanging edge or locking flange adapted to
prevent disengagement of the book and recess at that point and the opposite end
of one of the sections having a retaining spring adapted to prevent accidental
disengagement of the hook and recess thereat, substantially as described and for the
purpose specified.
2. A pipe thimble comprising two sections adapted to be connected and
disconnected for application to and removal from a pipe, and having an inner flange
provided with slits, and the spring arms 8 secured within said slits and extended
along inside of the inner face of said flange, substantially as described and for the
purpose specified.
