SYDNEY PITT of Sutton in the County of Surrey. IMPROVEMENTS IN TWO
WHEELED VEHICLES A communication from abroad by Peter Herdic of the City
of Philadelphia in the State of Pennsylvania, one of the United States of
America Merchant.
This Invention relates to improvements in two wheeled vehicles especially
passenger vehicles or cabs.
Its objects mainly are to obviate the shaking motion or less n the jolting of a
two-wheeled vehicle by the movements of the draft animal and to relieve the.
animal of the repeated blows ordinarily inflicted by the violent vibrations of the
shafts and load.
The improvements consist in a novel organization of parts and in certain
combinations of devices.
In the accompanying Drawings the improvements are illustrated as embodied in
a four seat passenger vehicle. The improvements or essential and cooperating parts
thereof, may however be advantageously used under some circumstances in
connection with other suitable vehicles.
Figure 1 is a side elevation, with the shafts partly broken away, and one of the
wheels removed.
Figure 2 is a plan view with parts in section, the driver's seat, boot, etc., being
removed to show the shafts and connections beneath the seat.
Figure 3 is a detail view shewing partly in full lines and partly in dotted lines
some of the parts represented in Figure 2.

page_text: Figure 4 is a detail view partly in elevation and partly in section on the line 4.4
of Figure 2.
A suitable axle, preferably having its cranks A, braced by inclined struts supports
the body A¹ upon the wheels. Supporting springs B, bracing springs C and a
rear spring B¹ or its equivalent, such as a cross bar, or brackets are provided.
The Drawings show but one main spring and one brace or bracing spring, and
these springs B. C. (as well as those which are not shewn) respectively connect at
their front ends with the lower and upper bearings or lugs b. b. at the ends of a
cross bar or bracket C¹. It is deemed preferable to have this lugged cross bar or
bracket connected with and supported from the body A¹, by means of brackets a. a.
(only one of which is shewn) which brackets are secured to or near the front
bottom corners of the body and respectively connect with the cross bar near its
respective ends and close to the lower lugs b thereof with which the main or
supporting springs are jointed at their front ends. The cross bar C, at each end
is connected with and supported from the seat frame or beams D. D. of the boot
floor by angle braces d. d. the front or longer arms of which are secured to the
beams inside the shafts and the shorter or rear arms having pivotal connection by
bolts d. d. with the shafts. A diagonal brace e. extends from the front of the
vehicle body bottom to the central beam E of the seat supporting framing. If
preferred, two diagonal braces might connect the vehicle body and seat framing
and extend from near the front corners of the vehicle bottom to the side beams D. D.
instead of the one brace e. extending from the front of the vehicle body bottom to
the central beam.
The shafts F have pivotal connection at their rear ends in advance of the axle,
with the skeleton work or frame timbers D. D. beneath the driver's seat F, and
close to the body of the vehicle. The pivotal connection of the shafts to the
vehicle is in this instance shewn as formed by means of two plates G. G. secured
to the shafts and provided with seats or sockets g. g. and two plates G¹. G'. secured
to the beams D. D. and provided with bosses or rounded lugs g¹. g¹. fitting the
sockets g. g. and secured by the headed bolts d¹. d. and nuts f. f. As these bolts
d¹. d¹. serve also to connect the shafts with the bracing angle brackets d. d. of the
supporting cross bar C, it will be obvious that vibration of the shafts about their
pivotal connection with the vehicle is not interfered with.
To prevent the up and down motion of the draft animal being imparted to an
injurious or disagreeable degree to the vehicle body and its load or the passengers
in the vehicle, a spring connection is made between the vehicle and the pivoted
shafts. In this instance the connection is made by a cross spring H connected
with the framing D. D. E. and attached at its ends to clip lugs or pendent supporting
brackets h. h. secured to the shafts. The shafts spring is shewn as firmly clipped
at its middle to a cross-bar I, beneath the floor or bottom J.of the boot and secured
to the beams D. D. E. by. bolts and nuts.
From the above description it will readily be seen that the motions of the horse
between the shafts are imparted to the vehicle through the medium of a spring in
advance of the vehicle body, which greatly lessens vibration of the vehicle and
avoids the violent, shocks, and annoying joltings to which the passengers in two
wheeled vehicles are ordinarily subjected, and also relieves the horse of the hurtful
strains due to violent vibration of the shafts and constantly occuring unyielding
blows upon his back.
I claim :-
First. The combination of a vehicle body, shafts having pivotal connection
therewith at their rear ends in advance of the axle, and the spring connecting
the shafts and vehicle, substantially as and for the purpose herein before set
forth.
Second. The combination of the axle, the springs the body, the pivoted shafts,
and the spring connection between the vehicle and shafts in advance of the vehicle
body and shaft pivots substantially as and for the purpose herein before set

page_text: Third. The combination of the vehicle body, the seat supporting framing, the
shafts pivoted to said framing at their rear ends and the spring connected with
said framing and with the shafts in advance of their pivotal connection substan-
tially as and for the purpose herein before set forth.
Fourth. The combination of the shafts, the frame-beams, the lugged plates, the
socketted plates, and the pivot bolts substantially as and for the purpose herein
before set forth.
'
Fifth. The combination of the cranked axle, the vehicle body the supporting
and bracing springs, the cross bar provided with the upper and lower bearings or
lugs at its end, the seat supporting framing, the pivoted shafts, and the angle braces
pivoted to the shafts and connected with the seat supporting framing substantially
as and for the purpose herein before set forth.
Sixth. The improvements in two-wheeled passenger vebicles substantially as
herein before described and illustrated in the annexed Drawings.
In witness whereof I the said Sydney Pitt have hereunto set my hand and
seal this second day of June in the year of our Lord One thousand eight
hundred and eighty two.
