Automatic Feed Device for Machines for Driving Clamps or
Staples.
I, JOSEF TEMLER, of Warsaw in the Empire of Russia, and 30 to 34 Taber-
nacle 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:-
The present invention relates to improvements in that class of machines which
serve to connect plates or sheets of soft material, such as cardboard and the like,
by sheet metal rivets of the type indicated in Figs. 3 and 4 of the accompanying
drawings, and in which machines the rivets reach the point of their application
from a magazine by gravity.
In particular this invention is an improvement on those machines of this class in
which the magazine is fed from a feeding plate or dish placed at the upper part of
the magazine.
This invention has for its object au arrangement by which the magazine is
automatically refilled from the feed plate or dish in a reliable manner and in the
same measure as the rivets are passed on for use.
This arrangement is illustrated in the accompanying drawings in which:
Fig. 1, shows it applied to a machine (shown in vertical section).
Fig. 2, is a plan view of the feed plate or dish.
a, is the plunger or piston for driving the clamps into the plate or sheet; h, is
the lever actuating the same; b, is a sleeve surrounding the plunger and sliding on
the same, serving to hold and guide the clamp or rivet which is under the plunger.
c, is a curvilinear channel guiding the rivets from the magazine, marked d, to the
point of application under the plunger a.
The arrangement for automatically supplying the magazine with rivets is as
follows:
A dish t, at the upper end of the magazine, is inclined towards the feed hole
thereof, and connected with the casing of the magazine by means of a joint g, as
will be seen in Fig. 1 of the drawings.
At the part opposite to the joint g, the rim of the dish carries a tooth z, directed
downwards, this engages with a toothed segment r, on the lever h, of the machine.
Both the teeth on the segment r, as well as the tooth z, have their sides so inclined
and rounded and their crowns of such wedge-like shape, that the tooth z, will
not be carried forward as in a toothed wheel, but must move in an upward
direction.
Consequently each tooth of the toothed segment causing a rising of the tooth,
and consequently of the dish t connected therewith, gravity causing the return
motion. The repeated up and down motion of the dish imparts a shaking
movement to the same.
As will be seen in Fig. 2, guide ribs, t t which are straight, and one t² which is
curved and near to the feed aperture of the magazine, are provided on the face of
the feed dish. That part of the dish which surrounds the feed hole is curved
downwards, the curve being most pronounced at the front part, or that point which
determines the position of the rivet in the magazine d.;

page_text: When the lever h of the machine is operated, shaking motion is imparted to the
dish by means of the segment r, and the tooth z, as already hereinbefore set
forth.
By this means the rivets on the plate and between the ribs t¹² t¹ are slowly
moved towards the feed hole. The shaking motion in conjunction with the position
of their centres of gravity cause all the rivets to be set up on their heads. In this
position they pass through the several passages of convenient dimensions which are
between the ribs t¹² t¹ and ultimately reach the downward curve of the dish which
surrounds the feed aperture, arriving at the steepest part corresponding with the
proper position of the head; the mandril in the magazine which projects somewhat
from the latter, bringing the points into their proper position also, so that the rivet
passes into the magazine properly.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed I declare that what I
claim is.
An automatic feed device for machines for connecting sheets or plates by means
of metal clamps or rivets characterized by:
(1) A dish or plate placed at the upper part of the magazine and inclined
towards the latter, having on its face guide ribs t¹¹ said dish being
connected with the casing of the magazine by means of a joint g.
(2) The tooth z, at the inferior edge of the dish referred to in Claim 1, and the
segment r, on the lever h, of the machine, imparting the shaking motion to
the dish or plate.
