MAGNETO-ELECTRIC IGNITION APPARATUS FOR USE WITH INTERNAL-COMBIISTION ENGINES.
Specification of Letters Yatent.
Patented Sept. 30, 1913.
Application filed March 9, 1910. Serial No. 548,201.
To all whom it may concern Be it known that I, CARL EBNER, a citizen of the German Empire, residing at Stuttgart, in the Kingdom of Wurttemberg, Empire of Germany, have invented certain new and useful Improvements in Magneto- Electric Ignition Apparatus for Use with Intcrnal-Combustion Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. In. certain forms of ignition apparatus al ready known the apparatus, or rather the magnets thereof, can be turned or in position in order to adjust the period of ignition, and in. these cases the distributer is also moved at the same time. In other forms of apparatus the distributer remains fixed in position being mounted on the stationary magnet casing, while the adjustment of the period of ignition is effected by causing the interrupter to break the circuit earlier or later.
The present invention relates to a magi'ieto-electric ignition apparatus in which the magnets can be adjusted in position in a stationary casing on which latter the dis tributer is fixed so that an unusually stable construction is produced.
The improvement is especially suitable for use in apparatus having what are called bell magnets, because with these it is possible to get the apparatus evenly balanced in all positions.
The improvement according to this invention further avoids the disadvantage, which is noticeable in apparatus with moving distributers, due to the displacement which frequently brings the electric cables into contact with the hot cylinders and pipes usually causing the cables to be burned and the working to be interrupted.
In order to suitably support the bell magnets at their front open ends, these ends are provided with special bearings fixed to the magnet. According to the present invention the borings for receiving the attaching means for the bearings are formed in the faces of pole shoes which can be inserted after the hardening of the steel magnets; the reason for this is that borings in the steel magnets themselves would become dis- 55 torted in the hardening and would therefore altered make it impossible to keep the patterns exact in form. At the other ends of the magnets where they are bent over, metal disks are fixed serving as attachment faces or working faces for the rear armature bear-1 ings and the hearings in the casing. The fastening of these armature bearings hit-herto caused serious difliculties 'in consequence of the fact that the faces of the magnets at the points in question were frequently not true in form after the hardening of the magnets.
The invention is illustrated in the accompanying drawings in a formof construction which is given by way of example.
Figure 1 shows a side apparatus; Fig. 2 shows a face view thereof; Fig. 3 shows a view corresponding to Fig. 1 partly broken away to show the parts of the mechanism in section'along the axis; Fig. 4 shows a vertical cross section; Fig. 5 is a detail view showing a vertical cross section through the attachment at the outer end of the magnet.
The apparatus according to the present invention is mounted in the casing a on which the usual distributer b is arranged in a fixed or permanent position as shown. In the casing a is the bell magnet 0, arranged so that it can be turned or adjusted; the magnet is of the usual form and is either made from a single bell magnet or from several bell magnets fitting one over another. The armature d which is provided with suitable windings (not shown) is arranged to rotate inside the bell magnet. The remaining portions of the apparatus including the means for carrying the current, for collect ing the current, for adjusting the period of ignition and so forth are then the same as those usually employed, and will require no description here.
For the purpose of providing a bearing for the magnet c'at its open end, it is equipped with the pole shoes f, in the end faces of which arcuate grooves f are provided in which corresponding projections e on the magnetand armature-bearing plate 0 will engage. The attachment screws 9 shown for this purpose in Fig. 5 engage only in the pole shoes f so that when the steel magnet c is hardened the borings for the screw 9 will not be affected.
In order to provide attachment faces for the rear armature bearing 11 and the magnet view of the whole bearing, plates 7;, are arranged at the bent over part of the magnet 0 at each sidie thereof, and aresuitably fixed for instane by mjeansmf rivets as shown.
5 I claim- In a magneto-electric ignition apparatus, the combination of a statlonary casing and having a bearin opening; a bell-magnet in said casing and aving poles of arc-shaped 10 cross-section and provided with arc-shaped grooves; plates in said bearing opening and rovided with arcuate rejections engaging m sald grooves; a shatt passing longitudinahy between the poles; an armature thereon; a distributer fixed to the casing and 15 operatively connected to the shaft.
In testimony whereof E aifix my signature, in presence of two Witnesses.
