COMPLETE SPECIFICATION.
An Apparatus for putting together Cycle Frames and the like.
I, REINHARD FELSCHE of 20 Abendstrasse, Magdeburg-Neustadt, in the German
Empire, Engineer, 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 :-
The machine illustrated in Figures 1 to 6 of the accompanying drawing is designed
for the insertion of the tubes in the connecting sockets of cycles and the like, and
by means of the same complete frames can be put together as well as single tubes.
The number of the frames operated upon at one time as well as of the supports
necessary hereto is unlimited.
In Figure the machine is shown in plan as containing a cycle frame in the
finished state, whilst the plan view
Figure 2 shows the setting and relative position of the separate frame parts
to one another before putting together or pressing together of the frame.
Figure 3 shows a section on the line A B (Figure 1).
Figure 4 a similar section on the line C D Figure 2.
Figure 5 is a section on the line E F (Figure 3) on a larger scale, and
Figure 6 is a plan view on G H (Figure 5.)
The machine consists of a bedplate a composed of one or more parts, having
guiding frames for the supports b and the adjustable arms c placed upon fixed
pillars for the support of the frame tubes. In the supports b are arranged the
bearings adjustable in all directions e (Figure 5); the pins i serve for the reception
of the connecting sockets f, whilst the crank holders of the cycle frames are
secured upon a fixed pillar g. The tubes to be put together are placed in the
bearings h arranged upon c. The pins of the bearing e move in globular
envelopes o and are adjustable in the direction of their axes both by means of the
perforated screw spindles kas also by means of the screw spindles n passing
The screw spindles
through the latter which are actuated by thumb screws m.
the matrices of which are placed in e act upon pieces arranged in e and adjustable
in the axial direction of e 1, which serve for the reception of the globular
envelopes o. The supports b are adjustable in themselves by means of the radial
and stepped guides, and consist of a combination of the latter and the guiding piece
for the bearing e. The pins are provided in front with a cone, for the purpose
in the case of any differences in the height or side position of the tubes to engage
the same first upon the advance of the supports and to effect the central guiding
of the same into the sockets fixed upon i. This operation is rendered easier through
the motion of the bearings o which admits of a motion of the pin in all directions
at the moment of the introduction of the tubes in the sockets. The pins are held
in their outermost position before the introduction of the tubes in the sockets by
means of a spring arranged in l, nevertheless upon the introduction of the tubes
in the sockets they will be pressed back into the piece and moreover to an extent
corresponding to the length to which the tubes engage in the sockets. After the
completion of the frames and the removal thereof from the machine, the pins i are
again pressed back automatically by their springs into the original position. The

page_text: connecting sockets f can also be thrust upon the tubes by means of the screw
spindle d and also by the advance of the piece by means of the screw spindles k.
This is desirable on the one hand in order to compensate in the putting together
of several frames for differences in the lengths of the tubes lying one over the other,
on the other hand in order that single tubes may be thrust into the sockets by means
of the screw spindles without having to set the supports b in motion.
In the Figures 3 and 4 the arrangement of the tubes and sockets above one another
and the bearing of the first upon the movable arms c is shown. As shown in the
drawing, the machine is arranged for the simultaneous construction of two equal
frames, but the same could also be made higher to operate on as many frames at
once as desirable. In order to be able to put together frames of different sizes and
such as require another angle of adjustment of the tubes one to the other, the single
side parts of the plate a forming the sliding surfaces of the supports may be joined
adjustably to one another in which case the machine had better be constructed not
as a closed polygon, but by the removal of one of its side walls preferably that shown
smallest in the drawing be formed open. Or if the simultaneous completion of a
whole frame at one time he not desired there might be placed upon a single straight
track replacing the plate a two supports, and thereby one tube of the cycle frame
after the other be inserted into the angle sockets, and so in various operations the
frame be put together.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. A machine for the putting together of cycle frames and the like consisting of a
plate with two or more adjustable supports thereof upon which pins revoluble in the
horizontal plane for the holding of the connecting sockets are placed whilst the frame
tubes are carried by holders between the said points in their axial line; which points
are moved axially by screws or the like and in this manner the connecting parts
fixed upon them are thrust over the ends of the tubes.
2. A machine for the putting together of cycle frames consisting of a frame plate,
which has a polygonal shape corresponding to the frame to be put together, and
sliding surfaces for the supports as set forth in Claim 1, which supports can be moved
upon the same by guiding spindles.
3. A machine for the putting together of cycle frames such as set forth in
Claims 1 and 2 in which several frames carrying the supports are placed one over
the other so that at the same time a corresponding number of cycle frames can be
operated on.
4. In the support frames hereinbefore described the arrangement that the sides of
the same are jointed to one another so that the side parts can be set at various angles
to one another, in order that cycle frames of various angular position of the tubes one 4
to another can be put together upon them.
