FRAME FOR MOTOR-BICYCLES.Specification of Letters Patent. Patented Oct.14,1913.
Application filed March 9, 1906. Serial No. 305,152.To all whom it may concern:
Be it known that I, EDWARD Y. WHITE,
citizen of the United States, residing at San
Antonio, in the county of Bexar and State
5 of Texas, have invented certain new and use-
ful Improvements in Frames for Motor-Bi-
cycles, of which the following is a specifica-
tion, reference being had therein to the ac-
companying drawing.
10 This invention relates to spring frames
for motor bicycles.
The object of the invention is to produce
a frame in which the motor engine may be
conveniently and compactly located, and
15 which frame shall be strong and stiff enough
for usage on ordinary roads, and sufficiently
yielding to afford a comfortable seat, and to
prevent breakage under ordinary conditions
of usage.
20 The invention involves in its construction
a combination of mechanical elements form-
ing a cushion for the motor and accessories,
as hereinafter described and claimed.
Figure 1 is a side elevation of so much of
25 a bicycle as is necessary to show the inven-
tion in a general way. Fig. 2 is a top plan
view of top tube and connections. Fig. 3 is
an elevation of the rear fork, and spring
head thereof. Fig. 4 is a broken cross sec-
30 tion of the front end of straps and hinge
hereinafter referred to, showing part of
tube 16. Fig. 5 is an enlarged detail eleva-
tion of the straps and hinge whereby the
sections of frame are jointed. Fig. 6 is a
35 plan and Fig. 7 is an elevation of the lower
rear frame member. Fig. 8 is a side eleva-
tion of the lower tube (front) of the frame.
Fig. 9 is a bottom view of the lower front
tube of frame. Fig. 10 is a broken cross sec-
40 tion of rear end of hinge and seat post tube.
Fig. 11 is a vertical central section of the
spring head of the rear fork. Fig. 12 is an
elevation of the slotted tube of the spring
fork head. Fig. 13 is a vertical section of
45 the cup piece of spring head. Fig. 14 is a
bottom plan of the cap 39' forming the up-
per end of slotted tube 38. Fig. 15 is a top
plan of the lower spring tube, and Fig. 16 is
a broken vertical section of the lower spring
5o tube.
The engine or motor 1, of usual form,
rests in a cradle, which cradle is composed
of curved straps 3, one strap at each side ofthe engine casing, and both connected to a
head 4, which head has a socket or pintle for 55
connection with the seat post 5, said seat
post being of usual construction. The straps
3 may be secured to the engine casing by
screws or bolts 6. The seat post 5 is rigid
with the top bar 7 of the frame, which bar is 60
hinged to a sleeve 8 rigid with the steering
head 9, through which head 9 the front fork
90 passes. Bar 7 has an inclined arm 12,
which arm has means of attachment to the
head of the motor, as by means of screw 13. 65
The bars of the frame are generally tubes,
as is usual. The engine, the straps 3, and
post 5, the top bar 7, and the arm 12 con-
nected to the engine, thus form a triangle,
which in itself is rigid. The attachment of 70
the straps 3 to the engine permits some lati-
tude in the style of engine which may be at-
tached to the frame.
The front fork 90 passes through sleeve 9
and turns therein, as is common. Sleeve 9 75
has a rigid collar 15, and to this the lower
front bar 16 is hinged. This bar 16 curves
below the engine, and has a cross head 29,
which is hinged to the head 4 at 32 just in
rear of the engine or motor cradle. (See 80
Figs. 1 and 5.)
The lower rear bars 17, 17 of the frame
are oval in form and tapering. Both these
bars are rigidly connected to a cross T 18,
which T is hinged between the straps 3 at 85
the front of the engine casing. The bars 17
thus straddle the frame bar 16, under the
engine. Bars 17 are rigidly connected to
socket 20, which socket 20 forms a bearing
for the usual pedal shaft. The socket 20 is 90
also rigid with the lower side bars 22 of the
rear part of the frame. Bars 22 are rigid
with the rear axle bearing 23. The rear
fork 24 is pivoted or hinged to the rear axle
bearing at 30. A tube 25 is rigid with the 95
rear fork, and serves as a receptacle for the
lower spring 33. Tube 25 has curved slots
34 in its upper end 35, which end is other-
wise closed. A cup 36, preferably secured
by screw threads to the lower end of tube 25, 100
serves as a means for assembling the parts
which form the spring head of the rear fork.
A slotted tube 38, having one end closed as
at 37, has its slotted end passed through the
curved slots 34 of the tube 25. The slotted 105
end of the tube -38 is externally screw1,075,886.
