EDWARD YOUNG WHITE, OF SAN ANTONIO, TEXAS.
BICYCLE-FRAM E.
SPECIFICATION forming part of Letters Pateat No. 677,830, dated July 2, 1901.
Application filed November 15, 1900. Serial No. 36,641. (No model.)To aZI whom it imay concern:
Be it known that I,EDWARD YOUNG WHITE,
residing at San Antonio, in the county of
Bexar and State of Texas, have invented cer-
5 tain new and useful Improvements in Bicy-
cle-Frames, of which the following is a speci-
fication, reference being had therein to the
accompanying drawings.
This invention relates to the frame con-
t o struction of motor-bicycles.
The object of the invention is to produce a
bicycle-frame which shall be yielding and
support the motor mechanism in such manner
that it shall be upheld by the part of the frame
15 which yields to the greatest extent without
adding appreciably to the rigidity of the
frame.
Figure 1 is a side elevation of so much of a
bicycle as will illustrate the invention. Fig.
o 2 is a broken plan, partly in section, of the
front lower bar of the frame. Fig. 3 is a side
view of said bar, partly in section or broken
away. Fig. 4 is a broken top plan, partly in
section, of the top bar of the frame. Fig. 5
25 is a plan detail of motor-supporting bracket
and connections to frame. Fig. 6 is a broken
side elevation, and Fig. 7 a broken plan, of
the said bracket and its tube.
The frame is made in sections, front and
30 rear, the front section being hinged to the
rear section at the top and elastically con-
nected at the bottom, so that the frame may
yield in itself. The front frame-section and
rear frame-section are rigid in themselves or
35 by their connections, as will be explained.
The front post 1 of the frame may be of
usual construction, having tubular bars 2 3
projecting rearward side by side from the
front post and a little distance apart toward
40 the rear end, so as to brace each other. The
rear ends of tubes 2 3 receive pins 7 7, which
are connected to cross-tube 5, with which
bracket 6 is integral or rigidly connected.
The cross-tube 5 has the pins 7 7 projecting
45 forward, so as to enter the tubes 2 3, and as
the frame-tubes 2 3 are brazed thereon the
frame-tubes are thus rigidly connected to the
bracket or hinge-piece 5 6. The cross-tube
thus forms a brace between tubes 2 3, and the
So bracket 6 serves as a means for attaching the
motor and seat-post, as will be explained.
The rear frame bars or tubes 10 11 are con-nected to the ends of cross-tube 5 by eyes 14
14, which are held to the ends of cross-tube
5 by a bolt or rivet 18, passing through both 5,
eyes and the tube 5. The pins 17 of the eyes
14 enter the tubes 10 11 and are there brazed
or otherwise firmly secured. The frame-bars
10 11 are connected by brace 12. The front
and rear sections of the frame are thus hinged 6c
together by pintle 18. The bars or tubes 10
11 connect to the rear axle-bearings, as usual,
as by bearing-pieces 19, to which the lower
rear bars are also connected. The lower front
bar 20 is rigid with post 1 and is connected 6c
by brace 21 to one or both of the top' frame-
bars 2 3. Thus while the front part of the
frame is hinged to the rear part by the hinge-
pin or pintle 18 the front frame-section is
rigid or firmly braced with reference to its 70
own longitudinal and upright members. The
lower rear bars 30 31 are connected to the
hub-supports 19, as usual. At the front these
tubes 30 31 receive the ends 32 33 of the dou-
ble tie-piece 40 and are rigidly secured there- 75
to. The double tie-piece 40 is preferably of
steel, having a fiat middle section which is
somewhat flexible. This piece 40 serves as a
support for the base of the motor 41, and the
piece 40 is preferably bolted to the motor 8o
both at front and rear. The front end of
piece 40 has ears 42, to which a piston-rod 43
is held by bolt 144. The piston-rod 43 ex-
tends into tube 20 and is surrounded within
this tube by a spiral spring 44. This spring 85
is confined between the piston-head 45 and a
bearing or cylinder head 46 at the end of the
tube 20. The piston-head 45 is preferably
screw - threaded, and the head or sleeve 46
screws into the end of tube 20. By the ad- 90
justment of either or both of these screws the
normal tension of spring 44 may be regulated.
The double tie piece or strap 40 is curved and
slightly flexible. It has a bearing 49 for the
shaft of the pedal-levers, and the bent por- 95
tion of the piece 40 affords a seat or saddle
for the motor 41. The upper end of the mo-
tor is firmly bolted to bracket 6 and the lower
end to strap 40, so that the motor-engine is
itself a brace or connection between the up- io3
per and lower bars of the frame.
The seat-post 50 is connected to the front
end of bracket 6 and is therefore supported
from the motor. The pedal-shaft 51, having
