Improved Self Feeding Arrangement for Rivetting Machinés.
I, JOSEF TEMLER, of Warsaw, in the Empire of Russia, and 30 to 34 Tabernacle
Street, Finsbury Square in the County of London, Manufacturer, 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 rivetting machines of that class which serve to unite
cardboard, leather, or the like by means of rivets such as shown in Figs. 1 and 2
of the drawings in which
Figs. 1 and 2 are respectively a front and side elevation of one of the rivets.
Fig. 3 is a vertical section taken on the line y y on Fig 4.
Fig. 4 is a plan of the feeding apparatus.
Fig. 5 is a vertical section thereof taken on the line xx.
Fig. 6 is a vertical section of an alternative arrangement.
Fig. 7 is a vertical cross section of the same on the line v v.
As will be seen in Fig. 3 such a machine consists substantially of an anvil a
serving to support the parts to be connected, and a plunger a vertically moved by
a lever and serving to force in and fix the rivets, the lower end of the plunger
being surrounded by a sleeve s¹ longitudinally moveable thereon. The latter holds
each sheet metal rivet brought under the plungers and serves to guide such rivet
whilst it is being driven into the parts to be connected thereby.
To enable the rivets to arrive under the plungers and into the interior of the
sleeves the thickness of the latter has an aperture at the corresponding point.
Into this aperture leads a channel o by means of which the rivets are fed to the
plungers in that position which they are to occupy under it in order to be applied
by the plunger to form a connection.
Automatically to supply to this channel with as many rivets (when the machine
is working) as it in turn supplies under the plunger s is the object of this improved
feed device.
As will appear from the accompanying drawings, this may be constructed in
various ways.
b
It however always consists of a receptacle provided at the upper part of the
channel c, the sheet metal rivets being poured into the receptacle, and a moveable
brush d having an alternating motion operating to conduct the rivets into the
channel c when the rivetting machine is in operation.
Figs. 3 to 5 show one construction, Figs. 6 to 7 a modification of this feed device.
In the former the bottom of the receptacle b assumes the shape of a concentric
groove, in the latter that of a funnel. In the construction illustrated by Figs. 3
to 5 the mouth of the channel c lies at the bottom of the concentric groove.
that shown in Figs. 6 and 7 it lies in the lowermost part of the funnel.
In
In either case the guide rib c', which forms part of the channel c and upon
which the rivets are guided down the said channel rises slightly above the bottom
of the receptacle b. The aperture surrounding this part c¹ is of such shape and
dimensions that it will only admit one rivet at a time and that only in a certain
position.
In the construction shown in Figs. 3 to 5 the brush d is keyed on a vertical
spindle e in the centre of the receptacle b. In Figs. 6 and 7 it is shown as working
on a horizontal arbor.

page_text: In the former case a toothed wheel is provided on the spindle e and a rack g
engages therewith; the latter is connected with an arm on the lever h. At
rach up and down motion of the lever the rack moves to and fro once, and thereby
turns the brush d first in one direction and then in the other, but the brush each
time makes only to of a complete revolution.
In the construction illustrated by Figs. 6 and 7 an arm i is provided on the
arbore of the brush, upon which acts (by means of a connecting rod k) either the
plungers or the lever h. In this case also each operation of the rivetting machine
causes a to and fro movement of the brush.
In both of these forms of feed device the brush will, first from one side, then
from the other, force a certain number of rivets contained in the receptacle b
towards the mouth of the channel c.
If the rivets are in the proper position they fall into the channel c otherwise
they are moved aside when the brush d reverses its movements and subsequently
again brought forward until, by the continued motion, they have been turned into
the proper position for entering the channel c.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
An improved feed device for rivetting machines characterised by a receptacle b
placed at the upper part of a channel c in which receptacle the rivets are moved
to and fro by the operation of a brush d actuated at each operation of the rivetting
machine either from the lever h or from the plunger s, by means of a toothed
wheel and a rack, or by a lever i and connecting rod k until the alternating
motion of the brush causes the rivets to assume the proper position and to fall into
the channel.
