COMPLETE SPECIFICATION.
An Improved Fastening Device for Machine Belts.
I, MORITZ MITTAG, of Berlin, Markusstrasse, in the Kingdom of Prussia,.
German Empire, Manufacturer, do hereby declare the nature of my invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The improved belt joint forming the object of the present invention consists of a
slightly arched plate having therein a slot provided with teeth cut in its longitudinal
edges, and the ends of the belt are joined and held tightly together by placing the
two said ends together with their interior faces contacting, and pushing both, thus
kept in position, into the slot of the said plate, on pulling apart the belt to put the
same over the pulleys the interior surfaces of the ends will be pressed more tightly
together whilst the teeth of the slot edges will penetrate the exterior faces of eac's
end thus forming a perfectly tight and reliable joint.
And in order to make the present invention more easily intelligible reference i
had to the accompanying drawing in which similar letters denote similar parts
throughout the several views:
Fig. 1 being a plan view of the joint.
Fig. 2 a cross section through the joining plate on line a
Fig. 3 a section through the said plate on line y y' of Fig. 1.
Fig. 4 a side elevation of the belt ends and plate and
Fig. 5 a plan of a modified form of plate.
Fig. 1.
The joining plate a is slightly arched as may be seen from Fig. 2 and its ends.
are turned down at 6 to give the plate a better finish. The said plate is slotted
longitudinally at c, the longitudinal edges of said slot being provided with sharp
teeth d on the opposing sides, each point or tooth being bevelled in the vertical
plane so that the apex lies at the lower surface of the plate a see Fig. 2.
The device is manipulated in the following manuer
The ends ee of the belt are placed together with their interior surfaces in
contact (Fig. 4) and pushed into the slot c of the plate a, so that when the belt is
stretched over the pulleys or straightened out as shown in Fig. 4, the interior
surfaces of the said belt ends will be more tightly pulled against each other whilst
the teeth or spikes & will penetrate the exterior surfaces and hold the said ends
securely together.
Fig. 5 shows in plan of a modified form of the invention in which the plate is
formed of two symmetrical parts a' b¹ connected together by means of rivets or
the like.
The advantage of a belt joint of the present construction is that it does not ruin
the ends of the belt as do most of the present devices and that it can be easily
taken apart and put together again whilst it is entirely impossible for the ends to
work loose and separate of their own accord, because, the greater the pull on the
belt the tighter the joint will become.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is :-
1. A belt fastener consisting of a curved plate a having end plates bb extending
downward from the same and a slot c extending across the said plate and bounded
at its ends by the said end plates and having a series of points d formed along each

page_text: of its opposing sides, each point being bevelled in the vertical plane, so that the
apex lies at the lower surface of the said plate a in the manner and for the purpose
substantially as described and shown.
2. A modified form of the device covered by Claim 1 according to which the
plate consists of two symmetrical parts attached by means of rivets or their
equivalents.
