Improvements in and connected with Cycle Frames.
I, CHARLES EDWARD TOMLINSON, of 111 Garfield Avenue, in the City of Syracuse,
County of Onondaga, and State of New York, United States of America, Draughtsman,
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 relates to cycles, and particularly to steering post heads therefor,
the connection of the frame-bars thereto, and the mounting of the steering post
whereby it is not only journaled therein, but also operates as a key to lock and retain
said frame-bars in their normal and relative positions; said frame bars being first
inserted into and across the bore of said head, and suitably brazed or secured therein
in such a manner as to make a smooth or flush joint exteriorly, and then being bored
transversely concentric with said head to create the double bearings for the steering
post, spaced apart to give steadiness theroto, and in such manner that said post is
not only journaled in said frame-bars within and concentric with said head, but it also
operates to koy said bars in their rospective positions and relations, in the head,
whereby if they, or either of them, become loosened in any manner they, or it, cannot
become separated from said head.
My invention consists in the improved construction and combination of parts
hereinafter fully described and specifically set forth in the claims.
It is constructed as follows, reference being land to the accompanying drawings
in which-
Fig. 1, is a side elevation of a cycle frame.
Fig. 2, is a vertical longitudinal sectional elevation of the head, the frame members
connected thereto, and the steering post in position.
Fig. 3, is a top plan thereof.
Fig. 4, is a vertical soction on line .x. x.
Fig. 5, is a like view on line y. y.
Fig. 6, is a like view of part of the head.
Fig. 7, is a like view of the frame-bar bushing therein.
Fig. 8, is a like view of part of one of the frame-bara, illustrating its
reinforcement.
A diamond frame is here shown as illustrative of my invention, but it will be
evident that any good mechanic can readily adapt the same to a drop-frame for
a ladies wheel.
This frame as shown, comprises a head 2 receiving a post 3, top frame bar 4, front
roach section 5, crank-hanger 6, roar forked reach section 7, rear fork 8, and
saddle post 9 all of which are of any desired construction except as specifically
pointed out.
This invention relates to the head, the mounting of the frame bars 4 and 5 therein,
and the journalling of the steering post 10 theroin, which is also of any desired
construction.
This head comprises a tubular body, provided with orifices 11 in its rear face
and in vertical aligument.
The frame-bars 4 and 5 are inserted through said orifices and their ends abut
against the opposite wall, boing suitably beveled, scarfed, or cut to fit closely against
the inner wall of said head, and they are suitably secured thereto and to the edges

page_text: of said ofifices, as by brazing. Bushings 12 and 13 bored transversely and vertically
are secured, when desired, in said head in proper position to receive said frame-bars,
to which they are secured, giving additional bearing, or brazing surface therefor.
Then said frame-bars aro borod transversely and in parallelism to and concentric
with the walls of said head; to receive said steering post, which thus has more or less
bearing in each frame-bar, at soparated points, thus steadying said post. Suitable
ball-bearings 14 and 15, are provided, and 16, is a suitable cap, or cup-nut to close the
top of said head.
The upper ond of said steering post is here shown as split so that the nut 16 will
compress it, so as to grip the handle-bar stem 17.
It will be seen that the steering post has a double bearing in said frame-bars, and
also operates to hold or key thein in said head, preventing them from displacement
even though they get loose, or are poorly brazed, and the security of their connection
to the head is thus maintained at all times, and to some extent, at least, the joints are
relieved from the effects of the strains thereon, and reinforced by said post.
The frame-bars are usually reinforced by thickening their ends, substantially
as shown.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to bo performed, I declare that what I
claim is :-
1. In a cycle, a head comprising a tubular body having side orifices, frame-bars
inserted through them and secured to their edges and to the opposite wall of said
body, and bored vertically concentric with the walls of said body.
2. A cycle bead comprising a tubular body, frame-bars inserted transversely
through its side and secured therein, and then bored vertically concentrio with
said body, in combination with a steering post inserted through and having double
bearings in said bars within said body.
3. A cycle head comprising a tubular body, bushings therein bored transversely,
frame bars inserted transversely across said head and through said bushings, and
then bored vertically concentric with said body in combination with a steering
post inserted through said frame-bars and bushings and having its bearings
therein.
4. A cycle head comprising a tubular body, bushings therein bored transversely,
and vertically concentric with said body, frame bars inserted across said body and
secured in the transverse bores of said bushings, and then bored concentric with, said
body, in combination with a steering post inserted through said frame bars. and
bushings and having its bearings therein.
5. A cycle head comprising a tubular body and transversely perforated frame bars
secured therein and transverso thereto, in combination with a steering post inserted
through said frame bars within said body.
