A communication from abroad by THE POTTIER AND STYMUS COMPANY, a corpora
tion organized under the laws of the State of New York, United States of
America.
I, REGINALD WILLIAM JAMES, of the Firm of Fell and James, of 1, Queen
Victoria Street, in the City of London, Chartered Patent Agent, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to car seats and particularly to means for supporting and
guiding the striker arms to permit them to shift from one side of the seat to
the other. It is the object of my invention to provide such a supporting and
guiding means as will allow the shifting of the striker arms and back to be
performed with greatest ease, and with this end in view my invention includes
ball bearing supporting and guiding means for the striker arms.
My invention therefore comprises a ball bearing car seat and the features
thereof are shown in the accompanying drawing, in which:-
Figure 1 is a side elevation of part of the supporting frame with the striker
arms and attached parts, some of the parts being removed.
Figure 2 is a front view of the lower part of the seat.
Figure 3 is a detail sectional view.
The striker arms 1 are attached to the sides of the back in any ordinary
manner. The seat frame is provided with curved guide ways 2, and these, as
shown in Figure 3, are of tubular form in cross section. The striker arms pass
down through these tubular guides which have flanges 3, 4, at their upper and
lower edges between which the striker arms move. At an intermediate point on
each striker arm lateral extensions 5 are formed and located within the tubular
guides and on the ends of these lateral extensions the ball bearings are placed
which consist of a divided sphere or ball 6 fitted to the cylindrical interior of
the guide way. The sections of the ball turn freely on a pin 7 which is fixed in
the striker arm. Between these sections of a ball and the striker arms ball
bearings S are formed by circular grooves in the meeting faces of the striking
arms and ball sections, said grooves containing the anti-friction balls 9. By
means of this ball bearing supporting and guiding means there will be no binding
action between the striker arm and its guide way and the seat may be shifted from
one side to the other with the slightest effort.
On the outer side of the guide way a track 10 is formed or provided and upon
this track a roller 11 runs, which roller is carried by a pin 12 on the striker
arms.
The striker arms extend downwardly and have a cross bar 13 at their lower
ends which is engaged by slotted levers 14 pivoted to the car frame at 15 and
carrying the foot rest 16.
It will be seen from the above that a double ball bearing effect is secured by
the large divided sphere or ball 6 and by the roller sections of this in connection
with the balls 8.
The use of the sphere is of particular advantage in preventing binding at
the ends of the seat in case the force used in shifting the back is not applied at
at the middle of the book

page_text: The guide ways enclose the ball bearings and hide them from view.
Having now particularly described and ascertained the nature of this said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
1-In combination, in a car seat, the frame, the guide ways, the seat back,
the striker arms, one at each end of the seat, and means for preventing binding
of either striker arm in its guide way should one end of the seat back be moved
in advance of the other, said means consisting of ball bearings one at each end
of the seat back presenting a spherical surface between each striker arm and each
guide way, substantially as described.
2-In combination in a ball bearing car seat, the tubular guide ways, the striker
arms passing through the same, the divided sphere carried by the striker arms
and fitted to the interior of the tubular guides and the ball bearings between
the parts of the sphere and the striker arms, substantially as described.
3 In combination in a car seat, the frame having the guide way, the striker
arm, a rolling section loosely journalled on said striker arm and having one
face lying adjacent to said striker arm and its other face of spherical form and
the anti-friction balls between the adjacent faces of the striker arm and rolling
section, substantially as described.
4-In combination in a car seat, the frame having the tubular guide way, the
striker arm passing through said guide way, a pin on the striker arm, rolling
sections one on each side of the striker arm journalled loosely on the pin and
having spherical surfaces fitted to the tubular guide way and ball bearings between
the adjacent faces of the striker arms and the rolling sections, substantially as
described.
5 In combination in a car seat, the seat frame having the hollow or tubular
guide way thereon, and striker arm passing through the guide way, the anti-
friction bearing within the hollow guide way, a track on the outer side of the
guide way and a roller carried by the said striker arm and engaging said track,
substantially as described.
6-In combination, the car seat frame having guide ways, the striker arm
passing through said guide way, a rolling section on each side of said striker arm,
each adapted to have independent turning movement, a pin carried by the said
striker arm and upon which said rolling sections are loosely journalled and ball
bearings between the adjacent faces of said rolling sections and the striker arms,
substantially as described.
7-In combination, the seat frame, the seat and striker arms mounted thereon,
the back carried by the striker arms, the hollow guide ways through which
the striker arms extend and the anti-friction bearings in the guide ways connected
to the striker arms, substantially as described.
8--In combination in a car seat, the frame, the guide ways, the seat back,
the striker arms one at each end of the seat passing through the guide ways
and a ball bearing at each end of the car seat between each striker arm and its
guide way, said ball bearing presenting spherical surfaces on each side of the
striker arm and between the same and each side of the guide way, substantially
as described.
9 In combination in a car seat, the seat frame, the guide ways one at each
end thereof, the seat back, the striker arms connected with the seat back and
passing through the guide ways and a ball bearing at each end of the seat between
each striker arm and its guide way, each of said ball bearings comprising a roller
section on each side of the striker arm, said roller sections having spherical
surfaces, substantially as described.
