Year: 1884

page_text: PROVISIONAL SPECIFICATION.
'I THOMAS M°GRAIT of 33 Church St Sheffield in the County of York
Sewing Machine Maker, do hereby declare the nature of my Invention for
IMPROVEMENTS IN PERAMBULATORS to be as follows:-
The first part of my Improvements relates to the making of the driving handles
of Perambulators in such a way as to be easily attached to either the back or front
part of the body, in order to enable a person to propel the same from the front or
back as desired, in order to effect this object I make two metal sockets one of
which I secure to the front and the other to the back under under part of the body
of the perambulator and upon the two lower ends of what are called the handle
lovers or back irons I make or secure a cross bar and in combination therewith
I form a tongue or plug of such size and shape as will fit exactly into the before
named Sockets upon the cross bar I also arrange a small lever spring latch so`
constructed that when the tongue or plug is forced into one of the sockets one end
of the spring latch falls or springs into a recess or cavity formed at the back part
of the socket or tongue or both together and thereby locks and secures the handle
to the body of the Perambulator by a slight pressure upon the opposite end of the
spring lever latch the tongue or plug may be released and placed into socket at the
opposite end of tho perambulator upon the outer end of the spring lever latch
I make a knotch or recess conveniently formed to hang thereon a parcel or satchel
and at the extreme end I form a ring or socket in which an umbrella or other
similar article may be placed and carried with safety.
The second part of my Invention has reference to the making of of the metal
tyres or rims of what are called spider or Bicycle perambulator wheels, I make tho
metal tyres in two side sectional parts and enclose or place the india rubber or
leather (which may be used) between the said side sectional parts and rivet or screw
the same together thus securing effectually the india rubber or leather which cannot
be easily displaced, The last part of my Improvements refers to an improved
construction of the hood joints or stretchers which are used for stretching or
forcing out the hood into proper shapo when required in use, hitherto joints have
been made with a shoulder formed on the outside to act as a stop when the hood
DSC.1

page_text: is stretched out in its proper shape this stop or shoulder has long been considered
objectionable on account of the fleshy part of the hand of a person when in the act
of opening it being caught therein and injured, to obviate this danger I make tho
outside of the joint quite smooth and even and in the place of making the outside
shoulder I make a half circular slot in what is called the he part of the joint and
pass a pin through a hole in the she part which also passes through the slot and is
rivetted on the outer sides of the she part of the joint it will be seen that when the
joint is being opened which works upon a pin in the usual way the stop pin by
coming in contact with the ends of the half circular slot prevents the joint from
being any further opened.

I THOMAS MCGRAH of 33 Church Street Sheffield in the County of York,
Sewing Machine Maker do hereby declare the nature of my said Invention for
IMPROVEMENTS IN PERAMBULATORS," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The first part of my improvements rolates to the making of the driving handles
of Perambulators in such a manner as to be easily attached, to either the back or
front part of the body; in order to enable a person to propel the same from the back
or front part thereof.
In order to effect this object I make two sockets one of which I secure to the
front part and the other to the back, preferably under part of the body of the
perambulator, and upon the two lower ends of what are termed the handle lovers
or back irons, I make or secure thereon, a cross bar, and in combination therewith
I form a tongue or plug of such size and shape as will fit into the before named
sockets, and upon the said cross bar I also arrange a small lever 'spring latch, 50
constructed that when the tongue or plug is forced into one of the sockets, one end
of the spring latch falls or springs into a recess or cavity, formed in the back part
of the socket or tongue or both together, and thereby locks and secures the handle
to the body of the perambulator, by a slight.pressure upon the opposite end of the
spring latch, the tongue or plug may be released and placed in the socket at the
opposite end of the perambulator-the outer end of the spring lever latch is formed,
in a convenient manner to enable a person to hang thereon a parcel or satchel so as
to avoid the necessity of carrying tho samo:-in addition thereto or in any other
convenient position, I attach a socket or spring ring in which an umbrella or other
similar articlo may be placed and carried-The second part of my improvement
refers to the making of what are called spider or Bicycle wheels and has for it's
object the better securing on the metal tyres india-rubber. or other material usually
employed thereon and also the more effectual fastening of the spokes therein;-for
this purpose I make the tyres in two side sectional parts, constructed in such form
as to receive a rubber or leather tyre, and by means of rivets or other convenient
manner I enclose and securely fasten the said tyres between the two sectional
parts, so as to prevent their being easily displaced.
The last part of my improvements has reference to the construction of the hood
joints or stretchers which are used to stretch or force out the hoods in the required
position and shape;-hitherto joints have been made with two shoulders on the
outer side of the knuckle so as to form a stop when the hood has been forced into
the required position,-in consequence of the liability of the fleshy part of the
hand being caught between the said shoulders whilst in the act of opening or
forcing the hood into its desired position and thereby becoming injured such form
of Joint has long been considered objectionable and dangerous-my improvement
entirely dispenses with any liability to any such casualty; in place of making the
shoulders as described the joint or knuckle part may be made perfectly round and
smooth, and in lieu of the shoulders I make in what is called the he part of the
joint a half circular slot arranged in such a manner co that when the he and she
part of the joint is pinned together in the usual way, by passing an additional pin
through the outer side of the she part of the joint, it also passes-into and through
the slot formed in the he part, by this arrangement it will be seen that upon
opening the joint the pin in the slot when coming in contact with either end.of.the
slot forms a stop.so as to prevent its further movement in that direction.

page_text: I will now with the aid of the drawings hereunto annexed in which similar
letters of reference indicate corresponding parts point out more particularly the
features of improvements herein described.
Fig. 1 is a plan view of the underside of the socket, with arms a¹ to attach to
the bottom of the perambulator, one of which is screwed under the front end and
another under the back end. Fig. 2 is a plan of the upper side of the same socket.
a is a shallow box, formed to receive the plate b. Fig. 3 shows the underside of
the plate b with the iron rods c c and handle d attached thereto. Fig. 4 is a side
view of a part of the perambulator e, with the irons and handle attached-f is
the socket for an umbrella. This is attached to the lever g which pivots on the
centre and has a spring i pressing it outwards. is a catch which holds the
handle in position Fig. 5 is a plan of the upper side of the plate attached to
the side rods c and Fig. 6 is a plan of the under side of the same. The handle is
removed by simply raising the end of the lever g, which disengages the hook k,
when the plate b can be drawn out of the box or socket a.
Figs. 7 and 8 represent my method of forming the tyre of the wheels. is the
tyre formed in two parts and rivetted together by rivets m, the spokes n being
wedged into recesses, where remain jammed between the flanges. o is the india
rubber tyre.
Figs. 9, 10 and 11 fully explain my method of forming the hood stretcher.―The
end is fitted in the forked end q; a centre pin is placed at r, to form the joint,
and a pin s in a works in the slot s' and limits the amount of rotation. Fig. 11
shews the two ends together.
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
Firstly the arrangement of a plug or tongue and socket in combination with the
spring lever latch or satchel carrier and socket or ring as herein described and the
combination of a satchel carrier and socket or ring for the purpose of holding or
_ carrying an umbrella or similar article in combination or attached to a perambulator
as herein described or any-modification_of_the_same.
Secondly the making of iron tyres in two side sectional parts of perambulator
wheel so ns to be enabled by riveting or otherwise securing the same together to
enclose and secure between the same the india rubber or leather tyres usually
employed thereon, substantially as described.
Thirdly the constructing or making of the joints or stretchers for the hoods of
perambulators with a slot in the he part thereof and the passing of a pin through
the she part and through the said slot to act as a stop or any modification of the
same substantially as described.
Dated this 11th day of October 1884.
