An Improved Machine for Connecting or Binding Together Various
Articles by Means of Sheet Metal Clamps.
I, JOSEF TEMLER, of Warsaw, in the Empire of Russia, and 30 to 34, Tabernacle
Street, 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 :-
In those machines, adapted for making connection by means of sheet metal
clamps, wherein these clamps are automatically fed to the point of connection,
under the stamp, or die, adapted, by descending, to drive the clamp or pin into the
articles to be fastened together, the magazine, as hitherto constructed had to be
filled with fastening pins, or clamps, by an operative, and recharged with fresh
supplies of such clamps whenever it was emptied by the operation of the
machine.
The object of this invention is to save the additional labour of refilling the
clamp magazine, by an improved attachment or accessory device intended to be
used in conjunction with a machine for driving in fastening clamps.
The improved clamp-feeding device is illustrated in Figures 1 and 2 of the
accompanying drawings, while Figures 3 and 4 are detail views representing
specimens of clamps, or fastening pins, which the improved device may be employed
to supply to a machine.
In these drawings a is the stamp adapted to drive in the clamps into the material
of the boards, or sheets, to be connected; h is the lever operating the said stamp ;
b is an adjustable sleeve surrounding the stamp a and serving for to guide and
retain each clamp when it passes underneath the stamp a. c is a curved channel or
shoot arranged to conduct the clamps k from the magazine, indicated in the
drawings by the letter d to the sleeve bi.e. to a suitable situation underneath the
stamp a.
For the automatic filling of the said magazine d the following arrangement is
employed.
The clamp-
At the upper end of the said magazine d is arranged a dish e.
guiding rod d', erected within the magazine d, protrudes a little distance above
the bottom surface of the dish e. This surface of the dish has a gradual
downward bend formed in it in front and on both sides of the said guiding-rod
or core d¹. This is indicated by shade lines in the plan of the dish, Fig. 2 of the
drawings.
The operation of the improved clamp feeding mechanism is as follows.
Whenever the stamp or die descends upon the boards, or sheets, or other flat
articles to be bound together with clamps, it invariably causes a certain amount of
vibration which, by shaking the whole of the clamp-driving machine, is communi-
cated also to the dish e. A slight movement is imparted thereby to the sheet
metal clamps, a certain quantity of which has been placed before-hand upon the
dish e.
The consequence is that those of the clamps which happen to be near the
downwardly sloping entrance of the shoot or magazine are conveyed into such
entrance. By properly arranging the curve given to the bottom of the dish at that
point, and giving an appropriate shape to the projecting end of the guiding rod or
core d', the result is attained, that each clamp as it approaches the magazine orifice,
in consequence of repeated vibrations, eventually assumes that position which it
should occupy during its passage through the magazine d.

page_text: As, for driving in each individual clamp, more than one stroke of the stamp or
hammer are always necessary, it follows that, during the insertion of each clamp,
the clamps placed upon the dish e. are always shaken several times in succession,
and therefore, whenever one clamp is driven home into the articles to be joined,
the supply of a fresh clamp from the magazine may with almost absolute
certainty be relied upon. It has been found by experiment that the operative
need only in a very few cases interfere with this feeding attachment by regulating
the feed by hand.
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
1. In machines for forming connections by means of sheet metal clamps, an
arrangement for automatically feeding the clamp magazine, characterized by a
dish e arranged at the upper end of the magazine d., the bottom surface of which
dish, in front and on both sides of the guiding rod or core d', protruding somewhat
above the bottom of the said dish, is curved downwards in such a manner as to
cause the clamps placed upon the said dish, by the vibration resulting from the
operation of the machine, to be conveyed into the magazine orifice or entrance and,
by the co-operation of the curve in the bottom of the dish and of the projecting end
of the core d¹ to assume the position necessary for entering, and passing through,
the said magazine d.
2. The improvements in apparatus for feeding sheet-metal clamps into the
machine for fixing them, substantially as hereinbefore described and shown in the
drawings.
