PROVISIONAL SPECIFICATION.
A New or Improved Combined See-saw and Mail-cart or Gig
for Children.
We, THOMAS JOHNSON, of Station Street, Huddersfield, Yorkshire, Piano Dealer,
and ALBERT HANSON, of Imperial Arcade, Huddersfield, aforesaid, Musical Instru-
ment Repairer, do hereby declare the nature of this invention to be as follows:-.
This invention has reference to a new or improved combined see-saw and mail-cart
or gig for the use and amusement of children.
In order to carry out our invention, we employ two or more wheels of light
construction, mounted on a suitable axis to which is attached framework and one
or more handles or shafts by which the cart may be drawn along; or the handles
or shafts may be so arranged and connected with the axis of the wheels as to form
the body or framework of the cart. Mounted centrally in suitable bearings or upon
a pivot above the axle of the cart is a flat board or plank of any desired length
and width, each extremity of which is provided with sides and back to form the
seats, wherein the children may be seated and made secure, if necessary, by a
suitable contrivance. For the purpose of imparting a reciprocatory up and down
motion to the flat board, we may employ cranks, cams, or levers, or any combination
thereof or other equivalent mechanical contrivance to which motion is given either
direct from the axle of the cart or from an auxiliary shaft or wheel driven by tooth
or chain gearing from the said axle, whereby as the cart or gig is drawn along, a
reciprocatory up and down or see-saw motion is imparted to the flat board, and the
children seated at each end are both ridden and enjoy the motion of a see-saw at
the same time. Suitable cross bars or rods forming stop pieces are employed at
each end of the cart to prevent the descent of the see saw beyond the limit of the
downward motion given by the means previously mentioned.
Whenever desired, the means for imparting the reciprocatory up and down motion
may be disconnected from the flat board and the latter supported in a horizontal
position by suitable stay rods or supports connected with the body of the cart which
then forms an ordinary go-cart.

A New or Improved Combined See-saw and Mail-cart or Gig
for Children.
We, THOMAS JOHNSON, of Station Street, Huddersfield, Yorkshire, Piano Dealer,
and ALBERT HANSON, of Imperial Arcade, Huddersfield aforesaid, Musical Instru-
ment Repairer, 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 :-
This invention has reference to a new or improved combined see-saw and mail-cart
or gig for the use and amusement of children.
In order to carry out our invention we employ two or more wheels of light
construction mounted on a suitable axis to which is attached framework and one or
more handles or shafts by which the cart may be drawn along.

Mounted centrally in

page_text: suitable bearings or upon a pivot above the axle of the cart is a car of any desired
length and width, each extremity of which is provided with seats, wherein the
children may be seated and made secure. For the purpose of imparting a rocking or
reciprocatory up and down motion to the car, we may employ cranks, cams, or levers,
or any combination thereof or other equivalent mechanical contrivance to which
motion is given either direct from the axle of the cart or from an auxiliary shaft or
wheel driven by tooth or chain gearing from the said axlo, whereby as the cart or gig
is drawn along, a rocking or reciprocatory up and down or see-saw motion is imparted
to the car and the children seated at each end are both ridden and enjoy the motion
- of a see-saw at the same time.
In order that our invention may be better understood, we will now make reference
to the accompanying sheets of drawings illustrative thereof, wherein Fig. 1. is
elevation of our improved mail cart, see-saw, or gig, and Fig. 2 is plan view of same.
Fig. 3 is an enlarged section through the line a b of Fig. 1; and Fig. 4 is section
through the line c d of Fig. 3. Letter e represents a carriage mounted upon wheels f
provided with handles or shafts g and also with legs or feet h. The wheels frevolve
loosely on each end of the horizontal bar or shaft i made secure to the underside of
the carriage e by bolts and set screws, j. Within the said carriage e is a car k sup-
ported on pivots at each side of the said car and working in fixed sockets m made
secure in the framework of the carriage e. The car is provided with two seats n
placed opposite each other, and also with footboards o, as will be well understood. The
car is provided with stays or rods p which prevent the children from falling out
sideways, whilst the said stays assist in strengthening the car.
This car is made to rock or oscillate upon its pivots l, the movement necessary for
giving the rocking motion being obtained in the following manner : The metal
nave or hub of one of the wheels fhas cast with it a pinion wheel which drives a
spur wheel in gear with the said pinion. The axle s of the spur wheel r is cranked
as shewn in Figs. 2 and 3 such cranked shaft being connected by links s¹ to a rod t
attached to brackets underneath the car k; it is therefore obvious that when the
carriage e is made to travel in either direction that the crank will give to the car k a
rocking or oscillating motion so that children, whilst being carried along in the car,
will also receive an up and down or rocking motion. It is also obvious that instead
of the car being made to rock by a crank and link as herein shewn and described,
that the same motion may be obtained by either an eccentric or cam.
The spur
wheel in gear with the pinion q is kept in the position shewn in the drawings of
Fig. 3 by means of a lever arm u connected by pin to the inner side of the carriage e,
such lever arm resting upon the cranked shaft s and close up to a collar w on the said
shaft, so that end wise or lateral movement of the spur wheel is prevented. If,
however, the rocking motion of the car is not required, the lever arm u is raised into
the position shewn in dotted lines in Fig. 4, whereby the cranked shaft s with the
spur wheel upon it can be drawn end wise so as to place the spur wheel out of gear
with the driven pinion g as shewn in dotted lines Fig. 3, in which case the crank
would cease to be operated, but in order to make the car stationary and fix it in a
horizontal position when not rocking, I employ rods or pegs a connected to the
chain y, which can be inserted into holes formed in both the carriage and car.
A modification of the means for stopping the rocking motion of the see saw is
shewn at Figs. 5 and 6 and consists of bracket A secured to the body of the carriage e,
one portion of the said bracket forming a toothed segment. It must be understood
that the bracket A is not lineable with the toothed wheel i so that when the toothed
wheel is in gear with wheel i it is out of gear with the segment A, and vice versa :
when in gear with the bracket A it is out of gear with pinion wheel i: therefore
when it is necessary for the car k to rock, the wheel is placed into gear with
wheel; but when it is necessary to stop the rocking motion of the said car the
shaft s is pushed endwise as already described so as to remove wheel r out of gear
with wheel i into gear with the segment A, consequently the motion of wheel r is
stopped and the see-saw made stationary.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Firstly. In a mail-cart or gig, the combination therewith of a rocking or oscillating
car operated by crank or other like motion substantially as shewn and described.
Secondly. In a mail-cart or gig, the combination therewith of a rocking or
oscillating car, the motion of which can be disconnected and the car fixed as described
and shewn herein.
Thirdly. In a mail-cart or gig having an oscillating or rocking car, the employment
of lever arm u for permitting the mechanism which imparts the rocking motion to be
disconnected from the car, as described and shewn.
