Year: 1877

page_text: LETTERS PATENT to John Osmond, of Breakspear Road, New Cross, in the
County of Kent, for the Invention of "IMPROVEMENTS IN TWO-WHEELED
VEHICLES"
Sealed the 1st September 1877, and dated the 17th March 1877.
PROVISIONAL SPECIFICATION left by the said John Osmond at the
Office of the Commissioners of Patents on the 17th March 1877.
JOHN OSMOND, of Breakspear Road, New Cross, in the County of Kent. "Iм-
PROVEMENTS IN TWO-WHEELED VEHICLES."
The improvements consist in the application of a moveable hinged back or back
support attached and formed at an angle to the back seat, and hinged to the front
seat, so contrived that when the back seat is not required the hinged back support
may be turned down on the front seat, and at the same time raise the back seat to
form a back support, the back seat being held upright by the weight of the front
cushion or box seat pressing on the thrown-over hinged back support. The various
parts may be inade of convenient material as at present in use.
The improvements also consist in the application of a moveable lowering tail
board fitted on runners working on carriers, or in grooves, drawer fashion, or may
form part of the bottom of the vehicle in such manner that when it is necessary to
seat four persons in the vehicle, such tail board may be drawn out and lowered and
afford sufficient leg room for back seat occupants. The various parts may be made
of metal or wood, and the tail board hinged and supplied with a catch regulating
the amount of draw out, and if necessary a chain, and so be fixed and supported at
any desired angle.
The improvements lastly embrace treating three-springed vehicles with roller
attachments supplied to a cross-bar connecting the front ends of side springs, and
mounting on the ordinary span iron carrying the body, and connected with the
back spring, similar roller attachments, connecting the said front spring bar and
span iron together by convenient bracing, and on said rollers allowing the body of
the vehicle (with or without the shafts) to slide backwards or forwards, and so
balance, making and controlling such sliding movement by rack and pinion or other

page_text: convenient gear fitted to body of vehicle and under connecting bracing or frame.
The various parts may be made of any convenient material, the rollers of hard
wood or metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Osmond in the Great Seal Patent Office on the 14th September
1877.
JOHN OSMOND, of Breakspear Road, New Cross, in the County of Kent. "IM-
PROVEMENTS IN TWO-WHEELED VEHICLES."
The improvements consist in the application of a moveable hinged back or back
support attached and formed at an angle to the back seat, and hinged to the front
scat, so contrived that when the back seat is not required, the hinged back support
may be turned down on the front seat, and at the same time raise the back seat to
form a back support, the back seat being held upright by the weight of the front
cushion or box seat pressing on the thrown-over hinged back support. The
various parts may be made of convenient materials as at present in use.
The accompanying Drawing will serve to illustrate a mode of performing my
Invention, but I do not limit myself to the exact mode shown, as it may be varied in
detail without departing from the nature of my Invention.
Figure 1 is a plan showing back and front seat down, ready for use, with the
hinged back standing up between said seats; Figure 3 is a side view of Fig. 1,
showing seats hinged, and also one in dotted lines, which represent said seat when
lifted, to allow of the position of the seats shown in Fig. 4, where one seat forms
a back, and the back which is hinged is folded down and placed under the seat
which is arranged to receive and cover it; Fig. 2 is a plan view of the same arrange-
ment, as shown in Fig. 4.
I claim the construction and use of moveable hinged backs or back supports
attached to seats of vehicles, and the arrangement of said seats to form back supports
when desired, substantially as and for the purposes described.
In witness whereof, I, the said John Osmond, have hereunto set my hand
and seal, this Thirteenth day of September, in the year of our Lord One
thousand eight hundred and seventy-soven.
