E. KASELOWSKY in BERLIN. Attachment of wheel tires to wheels for railway purposes.

Patented in the German Empire on July 4, 1877.

Of all attempts made to attach wheel tires to railway wheels, the so-called mansell ring best proven. The wheel tire is here by two, the lower one Partly held by the same hook-shaped clasping rings, which are held against each other and with the Rade are connected by individual screw bolts.

It has been shown that with this fastening the wheel tires are still securely on adhere to the wheel and do not involve any danger to operation, if the bandages are used on purpose were cut transversely in individual places.

However, the way the construction is closed, as a result of the individual bolts that are used Fastening are necessary, at least some uncertainty in itself, since the bolts come off and can make the ring loose, apart from the significant additional cost that such a Wheel, as well as the partial difficulty of the rings afterwards with old wheel constructions to bring into application.

The executed attachment, which is shown in more detail on the following drawing, avoids all bolts, wedges or screws and makes it almost impossible to loosen the actual fastening ring.

In addition, it has the considerable advantage of greater cheapness, and furthermore the essential advantage that it can be attached without difficulty to any iron wheel, regardless of its construction, or retrospectively, at low cost.

A is the wheel hoop, B the lower hoop, C a ring made of a metal or a metal alloy, which engages in the form of a dovetail or hook in both the wheel hoop and the under hoop.

After the indentation required to accommodate this ring has been machined in the wheel, as in the bandage, and the wheel ring itself has been warmly wrapped up in the usual manner as before, the metal or metal alloy that will form the ring C is determined is poured through the openings D, D, D in the liquid, ie molten state. With the old wheels, the filling can be done through the drum screw holes that are almost always present.

The material of the ring can be made of bronze, white metal or any other, less difficult or difficult to melt metal or a metal alloy of sufficient toughness or strength, depending on which one prefers the ring, respectively. The tire can be replaced by melting it out or by cutting the latter into two parts by a vertical incision in the middle from the periphery, and then turning the ring C itself out afterwards in order to prepare the wheel for receiving a new fastening ring.

Since the shape of the ring is chosen so the level DAF a gröfseres MAFs than the width has, then the pages are the shrinkage on cooling firmly against the drum and geprefst Sub tire ^, Bandage and lower frost thus as it were solid contracted. Furthermore, since the ring itself is surrounded on all sides by a solid, closed material, there is no risk of loosening or loss of the ring itself.

It will keep perfectly safe and serve its purpose even if the pouring should have taken place imperfectly in individual places or the corresponding ones Openings in the bandage and the lower hoop when grouting are not exactly on fit each other.

Since the ring also connects the upper hoop with the lower hoop through the dovetail-shaped or hook-shaped engagement, holds tightly together over the entire circumference of the wheel, so you sleep the construction, with great simplicity and cheapness, with greater certainty the same advantages in itself, which the Mansell ring offers and avoids its disadvantages, especially those difficult production and the unsafe fastening of the rings by the bolts.

If, however, you should prefer for individual cases, the attachment is visible to the eye to make or a metal respectively. to use a metal alloy that has a high melting

Bring application, as is explained in more detail in Fig. Ι by the dotted cross-sections E, E. When it becomes necessary to remove the bandages, the rings are then removed from the Side out, just pierced on the lathe and the poured metal is easily through To prepare the ring grooves for fitting a new bandage.
