Improvements in Perambulators.
I, URIAH MCCLINCHIE, of 219 Grand Street New York, in the County of
New York and State of New York, United States of America Manufacturer, 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:
My invention relates to what are known as childs carriages or perambulators,
and more particularly to that class of the same that have the body suspended on the
gearing by coiled springs. The object of my invention is to provide a strong, cheap,
durable and sanitary perambulator, and in effecting my purposes I have adopted
certain new and novel features more fully explained by referring to the accom-
panying drawing in which, like letters refer to like parts in each.
Figure 1, is a perspective drawing of perambulator.
Figure, 2, is the swinging body frame.
Figure 3, is an enlarged drawing of the push bar springs and portion of the
angle iron frame and canopy bar.
Figure 4, is a plan view of the brace bars and canopy holder.
Figure 5, is a side view of the same showing the clamp screw of canopy bar.
Figure 6, shows a side section of the tire of the wheel.
Figure 7, shows a detail of the tread of the tire.
Figure 8, is a top view of a round elastic button.
Figure 9, is a section of the same.
Figure 10, is a section of the tire showing the punctures and elastic buttons in
position.
Figure 11, shows top view of a long elastic button.
Figure 12, is a section of the same.
A, is the body of the perambulator. A¹ is the edge or rim. B is the swinging
frame. C is the angle metal frame. C'is the push bar. C' is the spring hook.
C³ is the hole through which the canopy bar passes. D is the helix spring. D₁ is the
terminal coil formed in the shape of a hook. D2 is a covering for the spring. E is
the brace bar. E is the canopy holder. E' is a clamp screw. Es are ends of
brace bars with eyes for rivets. is the wheel. F' is the tire. F2 is the punctures
in the tread of the tire. G are the elastic tire buttons. G¹ is the flanged portion of
the elastic button.
The body A is made preferably of wire mesh. The manner of its construction is
peculiar and new. A piece of wire mesh or netting is cut of the proper size and
this is placed between two forming dies-a male and female die, and by pressure is
formed into the proper shape desired. The ends are then trimmed and turned in
by hand, forming the rim or selvage A'. This rim or selvage A' is made by coiling
a wire around the edge, and intermeshing or otherwise connecting it with or to the
wire mesh of the basket. This coil overhangs the basket proper as shown in the
drawings Fig. 1, and affords a safe and effectual means to lodge the basket
in the frame B from which it may be easily detached or lifted; the whole
basket including the rim is made of woven or coiled wire without a framework to
sustain it. After the shaping or forming is done, it is then japanned, galvanized or
electroplated. The object attained in either of these processes being the same
which is to weld or join the wires wherever they come in contact with each
other. This stiffens and strengthens the basket and adds but little to its material
weight.
Heretofore it has been the custom to make perambulators, with the body fixed
upon supports so that they can be only removed by a skilled hand and with great
trouble; it is my intention to overcome this objection by making the gearing

page_text: entirely distinct from the body and so arranged that a child can remove or replace
it; to this end I have made a frame B conforming to the shape of the body A, into
which the body fits and rests upon the flange or rim A'; but this frame is prefer-
ably incorporated with the rim and fixed permanently therein without in any wise
interfering with the plan and scope of this invention, the result aimed at being so
far as the body is concerned, the easily removing of the body from the gearing for
the purpose of thorough cleansing. This is effected by unhooking the springs at D₁
when the basket or body may be at once removed. I preferably make my body of
wire as it can be thrown in a tub and cleansed more thoroughly.
The main frame which consists of horizontal bars C C and the upright C of my
perambulator, I preferably make of angle iron, in order to get the greatest
strength with the least weight; the said frame bars having each an inwardly turned
horizontal flange a which is bolted directly to the axles, and a flange b arranged at
right angles thereto whereby this latter flange stands on edge and resists the down-
ward strain thereby preventing the longitudinal spreading of the frame and making
a frame that light, strong and attractive. I also prefer to make my push bar C
of metal. This push bar has hooks C or their equivalent for the purpose of con-
necting the helix spring with the gearing. It has also a hole through it, C³,
through which the canopy bar H freely passes.
The spiral springs D are the means of suspending the body to the frame; their
terminal coils D₁ are turned into hooks for easy and safe attachment to the frame
body; although I have shown a hook as a means of connection between the frame
and gearing such means are shown for their simplicity; other means may be used,
or the springs may be differently arranged, but so long as the body is sustained at
either end by helical springs attached to the gearing on one end and the body at
the other end, my object is attained; the springs are preferably covered as shown
Figure 3, D.
The main angle iron frame C has cross braces E; these are secured to the main
frame by rivets or screws passing through the eyes at E³ and through the inwardly
turned flanges a of the angle irou frame. At the central point where these braces
cross on the upright position of the main frame is a casting E¹, through which the
cross bars pass and through which the canopy holder H passes; this holder has a
set screw E to clamp the canopy bar or it may have a ball-and-socket joint; any
method of screwing the end may be used but for simplicity the clamp screw is
preferred. It will be seen by reference to Figure 1 that the canopy bar H passes
inside the push bar C¹ at C, this would be the best method in the event of the push
bar being made of wood, as a hole large enough to admit the canopy holder would
weaken the push bar where it should be the strongest; when the push bar is made
of wood a screw eye as a guide might be fastened to the push bar in order to retain
the canopy bar in position.
The socket E¹ located on the main frame is new; all such rests that I have seen,
being on the body of the perambulator. It is very essential that it should be
located, as I have shown, as the constant vibration of the body in my invention
would make it less effective if placed on the body.
The wheels F are preferably made of wire spokes, metal hub and tire.
The rubber continuous tires now used are not only expensive but when they
become worn are of no use. To obviate this, I have perforated my tire and
through these perforations force an elastic button or plate by having the back
portion of the plates G¹ flanged, Figures 9 & 12, and forcing that portion through
the orifice made in the tread of the tire to receive it, it is firmly held in position
and the pressure exerted on the front serves to maintain it in its position when the
wheels revolve on the ground.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :
1st. In a perambulator or baby carriage, the combination with running gear and

page_text: a body portion, of the metallic frame bars having inwardly turned flanges by which
they are bolted to the main axles and other flanges at right angles thereto whereby
they stand on edge to resist downward strain on the frame bars and prevent the
frame spreading in the direction of its length.
2nd. In a perambulator or baby carriage, the combination with its running gear
and body, of the angle-irou frame bars having inwardly-turned flanges, and flanges
standing on edge at right angles thereto, the brace-bars carried by the frame bars
and having their ends bolted to the inwardly turned flanges of the latter, said
brace bars having a socket at their point of crossing, a canopy bar adapted to be
secured in said socket, and a means for adjustably securing said canopy bar within
the socket.
3rd. In a perambulator or baby carriage, the combination with its running gear
and frame, of a body detachably suspended from the frame and composed of woven
wire having an exterior covering for the purpose of imparting rigidity and strength
to it, and a rim of coiled wire surrounding the upper edge of the body and projecting
beyond the plane of its sides for the purpose of enabling the body to be removed
and placed in position.
4th. In a baby carriage the basket or body formed of woven wire reinforced by
an outer covering thereby imparting increased rigidity to it, said basket having its
upper edge provided with a coiled wire portion which projects beyond the plane of
its sides, and a frame bar shaped to the contour of the body for keeping the edges
in position.
