This invention relates to improvements in
baby and doll carriage bodies and more particu
larly to improved top-frames of bodies and a
method of upholstering such frames which de
sirably are padded and which usually support the
main fabric body of the carriage in suspended
relation within the frame.

the frame is in the grooved form It. These
grooves 34 extend all around the frame. Fig. 8a
shows a cross-section of the frame as with the
grooves 35 therein. Fig. 110. shows a cross-sec

and the clamp tightened, the material 24 is de
pressed into the grooves 34, as in Figs. 12 and 13,
to effect an extremely secure holding of the body

Actually a wide variety of cross
sectional shapes may be effectively upholstered
according to my disclosed method. Also, it is
feasible to upholster frame members effectively
and with substantially uniform distribution of
size, as in Fig. 14.
It will be apparent from the foregoing dis
closure that I have provided an improved meth
od whereby carriage top-frames may be uphol
stered ef?ciently and effectively in a fraction of
the time required according to prior procedures.
Also my top-frames may be upholstered by un
skilled labor, whereas the upholsteringr of prior
top~frames required skilled upholsterers with the
heavy expense involved. Additionally, my in
proved method more efficiently and effectively
mounts the fabric carriage body on the uphol
stered top-frame, as compared with prior prac
tices and structures.
I claim as my invention:
1. An upholstered top-frame for a carriage
body, comprising a generally rectangular rigid
frame having padding in strip form distributed
uniformly on the top surface of the rigid frame,
a pre-fabricated generally rectangular covering
element of ?exible sheet material made of a plu
rality of strips each formed with generally chan
nel~shape cross-section and stitched together at
the corners of the rectangle, said covering ele
ment being disposed over the rigid frame with
said padding engaged in the bottom of its chan
around the body and laid against the under surface of the covered frame, and a rigid generally
rectangular clamping member clamping the out
turned margin of the body material against the
frame all around the rectangular extent of the
latter, said rigid top-frame having a groove in
its under side extending all around the frame,
and said clamping member having a comple
mentary rib at its top side depressing said turned
out margin of the body material into the groove
of the top-frame.
4. In a baby carriage and the like having a
body of ?exible sheet material, an upholstered
top- frame supporting said ?exible sheet body and
comprising a generally rectangular rigid top
frame member and a pre-stitched frame-covering
element of ?exible sheet material pre-shaped to
?t loosely over the top-frame and disposed there
over, padding material intervening between the
frame and the frame-covering element along at
least one covered surface of the frame, said
60 frame-covering element being drawn over the
padding material into tightly wrapped relation
to said material and frame, and a generally rec
tangular rigid clamping member secured to a
surface of the covered top frame which is sub
stantially free of the padding material with the
top marginal portions of the ?exible sheet body
securely clamped between the top frame and the
clamping member.
5. In a baby carriage and the like having a
nel, the opposite edge portions of the channel 70 body of flexible sheet material, an upholstered
top-frame supporting said ?exible sheet body
walls of the covering element being laid over
and comprising a generally rectangular rigid
