ATTACHIWENT
George B. Bentz, New York, N. Y.
Application August 30, 1937, Serial No. 161,650
9 Claims. (Cl. 4-185)
The invention aims to provide a new and im
proved seat attachment for bathtubs embodying
unique provision for adjusting according to the
width of the tub upon which the attachment is
5 used.
A further object is‘ to provide novel means
whereby the seat may be vertically adjusted.
A still further object is to provide a simple and
inexpensive, yet e?icient and desirable construc
0 tion.
With the foregoing in view, the invention re
sides in the novel subject matter hereinafter de
scribed and claimed, description being accom '
plished by reference to the accompanying draw
15 ings.
Fig. 1 is a transverse sectional view through a
relatively wide tub, showing one form of the in
vention engaged therewith.
Fig. 2 is a view similar to Fig. 1 but showing
20 the attachment adjusted to ?t a comparatively
narrow tub.
Figs. 3 and 4 are detail perspective views, the
positions shown corresponding to Figs. 1 and 2
respectively.

Fig. 5 is a view similar to Fig. 1 but showing in
elevation a different form of construction engaged
with a relatively wide tub.
Fig. 6 is a view similar to Fig. 5 but showing the
same device adjusted for engagement with a com
30 paratively narrow tub.
Fig. '7 is a detail perspective view of one end of
the attachment shown in Figs. 5 and 6.
Fig. 8 is a detail perspective view of a different
form of construction in which provision is made
35 for vertically adjusting the seat.
Fig. 9 is a detail perspective view showing a
construction similar to that of Figs. 5, 6 and 7
but without the adjustment for different tub
widths.
Fig. 10 is a view similar to Fig. 9 illustrating a
somewhat different pivotal connection between
the seat and the pivoted tub-abutting member.
Fig. 11 is a perspective view showing provision
which may be made for extending and retracting
’ the length of the seat if desired.
In the various forms illustrated, the seat is de
noted at 12, and while in most forms of con
struction, this seat may be inextensible, in other
5,0 forms it may be of extensible and contractible
nature as illustrated in Fig. 11. In Figs. 1 to 4,
it may be assumed that the seat is of wooden
construction but in the other views, a pressed or
stamped sheet metal construction is disclosed.
In each form of construction, two tub-abutting
members I 3 of general H-shape are provided at
the end portions of the seat l2, the horizontal rod
portion 14 of these H-shaped members being
pivotally received in transverse horizontal bear
ings connected with the ends of the seat, and the 5
vertical side members 15 of said H-shaped mem
bers 13 are ‘in all instances provided with means
to engage the opposite side walls IBof a bathtub.
While these characteristics are generic to all
forms, differences between said forms exist'which 10
will be fully explained hereinafter.
In the form of construction shown in Figs. 1
to 4, the bearings \I'! which receive the horizontal
portions 14 of the members 13, are formed on the
ends of arms 18, said arms 18 being pivotally 1-1
connected with the end portions of the seat
12 upon transverse horizontal axes in order
that said arms may swing inwardly or outwardly
longitudinally of the seat, to position the members
13 to abut the side walls 1-6 of a relatively wide
tub (Fig. 1) or a comparatively narrow tub (Fig.
2). In the preferred construction, there is a rock
shaft 19 underlying each end portion of thelseat
I2 and turnably mounted in bearings 20 secured
to said end portions, the arms 18 toward either
end of said seat being integral with the rock shaft
at said end.
The upper and lower ends of the side members
l5 of ‘the tub-abutting members 13 are provided
with laterally bent terminals 21 to abut the inner
sides of the side walls l6, and if desired, said
terminals could of course be provided with tips
of rubber or the like to overcome possibility of
injuring the enameled surface of the tub. This
is also true of the various other forms of con- 35
struction hereinafter described.
In Figs. 5 to 10 inclusive, the bearings 22 which
receive the rod'portion 14, are connected with the
seat 12 by being formed integrally therewith, and
in all of these ?gures except Fig. 10, the side 40
members 15 of the tub-abutting members I3 are
disposed at the outer sides of said bearings‘ 22.
In Fig. 10, however, the side members I5 are dis
posed at the inner sides of the bearings 22, and
the rod portion 14 projects laterally outward to
some extent from said side members as denoted
at 14a, for reception in said bearings.
In the form of construction shown in Figs. 5,
6 and 7, the upper and lower ends of the side
members 15 are provided with relatively long 50
terminals 23 projecting laterally in one direction
and with comparatively short terminals 24 pro
jecting laterally in the opposite direction. The
members l3 of these views may be swung to either
of two inverted positions to dispose either the
5
2
2,113,189
terminals 23 outwardly for contact with the tub
walls It, or the comparatively short terminals 24
outwardly for contact with said walls. When the
terminals 23 are presented outwardly, the attach
two H-shaped members disposed at said ends of
said seat and having their horizontal portions
ment is in condition to ?t a comparatively wide
tub. When the terminals 24 are presented out
wardly, the attachment will ?t a narrow tub.
Intermediate adjustments for tubs of other widths
ing provided with means to engage the side walls
may of course be provided by turning one mel 10
her [3 to present the terminals 23 outwardly and
by turning the other member I3 to present the
terminals 24 outwardly.
In Fig. 8, the side members l5 are provided at
one end with lateral terminals 25 to lie upon the
tub rim when the member I3 is in one position.
The other ends of the side members 15 are pro
vided with similar terminals 26 to lie upon the
tub rim when said member I3 is turned to an in
verted position. The rod portion M in this form
20 of construction is closer to the terminals 26 than
to the terminals 25. Thus, whenv member 13 is
positioned as shown in Fig. 8, the seat I 2 will be
relatively low but when said member I3 is swung
to an inverted position, the seat will be supported
25 at a higher position.
In Fig. 9, the member I3 is similar to that
shown in Figs. 5 to 7 but its ends are provided
with lateral terminals 21 of uniform length.
This is also true of the member l3 shown in

prising a seat, transverse horizontal bearing
means connected with the ends of said seat, and
two H-shaped members disposed at said ends of 10
said seat and having their horizontal portions
received pivotally in said bearing means, the
vertical portions of said H-shaped members be
ing provided with lateral terminals to abut the
side walls of a bathtub.
3. An attachment of the class described com

prising a seat, transverse horizontal bearing
means connected with the ends of said seat, and
two H-shaped members disposed at said ends of
said seat and having their horizontal portions 20
received pivotally in said bearing means, the
vertical portions of said H-shaped members be

of a bathtub when said H-shaped members are
in one position, said H-shaped members being
provided with additional means to engage the
bathtub side walls when said H-shaped mem
In Fig. 11, a seat is shown composed of tele
scopically connected sections‘ [2a and I2‘), each of
said sections having downwardly bent longitudi
nal ?anges 28 and inwardly bent longitudinal
?anges 29 at the lower edges of said ?anges 28,
the ?anges of the two sections being slidably

ing ?ange of the section l2".
By downwardly
springing the arm 38 to withdraw the pin 3|
from the opening 32 in which it was previously
received, the seat sections I2a and I213 may be
relatively adjusted to vary the length of the seat
as required, the pin 3| being received in an
other of the openings 32 to hold said sections in
relatively adjusted position. A seat of this na
ture, while usable with any form of the inven
tion, is particularly adapted for use with the
forms of construction shown in Figs. 8, 9 and
10, in which no other provision is made for
adapting the attachment to tubs of different
widths.
In the foregoing, numerous forms of the in
vention have been explained for illustrative pur
poses, but it is to be understood that the device
may also take other forms within the scope of
the invention as claimed.
While I have ex
plained inward and outward swinging of the
arms l8 (Figs. 1 to 4) to adjust the attachment
for tubs of different widths, such swinging by
changing the over-all length of the attachment,
may be used to vary the height of the seat l2
in a tub, for the shorter the attachment, the
lower it will ?t in the tub. Similarly, while I
have described inversion of the members l3
(Figs. 5 to 7) to adjust for di?erent tub widths,
70 such inversion may also be done to support the
seat at one height or another.
I claim:—
1. An attachment of the class described com

of a bathtub.
bers are swung to inverted positions.
4. An attachment of the class described com
prising a seat, transverse horizontal bearing 30
means connected with the ends of said seat, and
engaged. To one of the ?anges 29 of the sec
tion l2a, a spring arm 30 is secured, said spring
arm having an upwardly projecting pin 3| pass
40 ing through said ?ange and receivable in any of
a plurality of openings 32 formed in the contact
to
received pivotally in said bearing means, the
vertical portions of said H-shaped members be
bearing
means connected with the ends of said seat, and
nals projecting in one direction from their ends
to abut the side walls of a wide bathtub, said
vertical portions being also provided with rela
tively short lateral terminals to abut the side 40
walls of a narrow tub when said H-shaped mem
bers are swung to inverted position.
5. A structure as speci?ed in claim 1; said
horizontal portions of said H-shaped members
being closer to one end of said vertical portions
than to the other end thereof, for vertically ad
justing the seat by simply swinging said H~
shaped members to inverted positions.
6. An attachment of the class described com
prising a seat, arms pivoted to the end portions 50
of said seat on transverse horizontal axes to
swing outwardly or inwardly, the free ends of
said arms having bearings parallel with said
axes, and H-shaped tub-abutting members hav
ing their horizontal portions rotatably mounted 55
in said bearings, said tub-abutting members
having portions to abut the side walls of tubs
of different widths when said arms are swung
inwardly or outwardly.
'7. An attachment of the class described com 60
prising a seat, tub-abutting members at the ends
of said seat, and swingable means pivotally
carrying said tub-abutting members and pivot
ally mounted on said seat, said swingable means
being swingable longitudinally of said seat to 65
position said tub-abutting members to abut the
side walls of a narrow or wide tub.
8. An attachment of the class described com
prising, a seat, tub-abutting members invertably 70
connected with the end portions of said seat,
said tub-abutting members having relatively
long means to abut the side walls of a wide tub
when said members occupy one position, and
having relatively short means to abut the side 75
