WIRING MECHANISM FOR. AUTOMOBILE-ENGINES.

T 0 all whom it may concern Be it known that I, IRA H. SARE, a citizen of the United States, residing at Sentinel, in the county of Washita and State of Oklahoma, have invented certain new and useful Improvements in Wiring Mechanism for AutomobileEngines; 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.

This invention relates to wiring mechanism for the ignition system of automobile engines and particularly to the wiring for the primary circuit of a system in which a magneto and induction coils are included.

It is a well known fact that in some classes of automobile engines, the wires running from the timer to the primary coils, become saturated with oil and thus become short circuited and it is to obviate the trouble thus caused that is the primary object of my invention. I obtain this object by providing permanent wiring connection between the timer and primary coils, portions of the wires included in said connections being removable for renewal, at small expense.

Another object is to provide novel connect engine side of the dashboard, showing theconnecting means between the primary coils and the timer, Fig. 3 is a sectional view on the line 33 of Fig. 3. Fig. 4 is a view of a portion of the connection between the timer and primary coils. showing the timer in front elevation. and showing the metal case in side elevation, Fig. 5 is a vertical sec tional view through the metal case and adjacent parts, Fig. 6 is a bottom plan view of the metal case, and, Fig. 7 is a diagrammatic View of the wiring system of an engine in connection with which my improve ment is adapted to be used.

Referring more particularly to the drawings, in Fig. 1, 1 represents the front cylinder of a four-cylinder engine, 2 represents the radiator, 3 the dashboard and f the timer, the commutator of which is keyed or otherwise secured to the cam shaft of the engine (not shown).

The primary circuit in the system indicated in Fig. 7 extends from the magneto 5 to the commutator of the timer 4, through the timer to the primary circuit wires 7 and thence to the primary coils of the induction coils indicated at S. The secondary circuit extends from the secondary coils of the induction coils, through the secondary wires 9 to one pole of the spark plugs 10. through the spark plugs, which have'the opposite pole grounded in the engine, through the engine back to the magneto 5, which also may have one pole grounded in the engine casing.

As a rule the binding posts 11. of the timer are connected by single wire to the binding posts 12 of the primary coils and it is at the point near where the wires connect with the timer that oil and grease from the engine accumulates and saturates the wires and thus cause short circuiting.

In my improvement I connect the binding posts 12 of the primary coils each with an insulated wire 13, and these wires extend through one of the walls of a tubing 14 and are threaded through that tubing and proiect somewhat beyond the outer end 15 thereof (Fig. 5). As seen in Fig. 2. the inner end of the tubing rests against the front face of the dashboard 3, or that face which is nearest the engine, the binding post 12 of the primanv coils extending through the dashboard. The tubingis wound around a brace rod 16. which connects the upper portion of the radiator 9 with the dashboard, the front end of said tubing depending below tbe brace rod 16 and isspaced from the front of the cylinder 1 by means of a wire fork 17 which is secured to the cylinder 1 mv means of a bolt 18. said bolt being one of those which serve to hold the engine together.

A substantially cup shaped casing 19, made of aluminum or other metal. has a reduced end 20, which is headed as at 21, ex tended into the front end of the tubing and secured thereto by means of a clamp" 22. The lower end of the casing 19 is of con siderable greater diameter than the portion 20 thereof and a disk of fiber insulation 23 and is secured to the lower edges of the casing 19 by means of the threaded rim 24, which is provided with a flange for securing the disk 23 to the casing, a circular washer 26 being interposed between said flange and disk. At four diametrically opposed points the disk 23 is perforated, as at 27, and through these perforations extend bolts 28, the heads 29 of which bear upon the ends of the wires 13, said ends being twisted around 7 and against the nuts 39., or otherwise secured to the bolt 28, is the upper end of an insu- 'lated wire 34, said end being secured in place by means of the thumb nut 35. The lower end of the wire connects to one of the binding posts 11 of the timer, it being understood ,that each of the wires 13 is thus connected by means of one of the bolts 28 and by the wires 34 with one of the binding posts 11 of the timer. The connection between the timer 4 and the secondary coils is the same as before described.

The wires 3% are held in spaced relation from the front of the engine and are kept.

in an upright position, and are spaced from each other between the timer 4 and the casing 19, and are thus not liable to become oil soaked, but should they become soaked with oil and short circuited any one of them, or all of them, may be quickly and easily re- ,moved and new ones put in their stead at very small expense. In the ordinary system of this type the wires from the timer 4 are bound together and run horizontally to the frame of the automobile, along the frame under the lower edge of the hood and up to the dashboard where they are connected with the primary coils of the induction coils and, when they are thus arranged, it has been found that oil and grease from the engine becomes collected on the wires near the timer andgradually soaks through and thus causes short circuiting at that point. When the Wires became thus short circuited, it was necessary to remove the entire length of wire connecting the timer with the primary coils and this involved considerable trouble and expense.

The tubing 14 may be made of any flexible material which is water and fire proof, and if it is so desired, it may be made of insulating material.

Uopies of this patentfmay be obtained for Although I have described the preferred embodiment of my invention, I reserve and may exercise the right to make such changes in the construction, combination and er rangement of parts as do not depart from the spirit of the invention and the scope of the appended claims.

What I claim as new is:

1. In a wiring system for combustion engines for motor vehicles, the combination with a plurality of engine cylinders, of a timer positioned at the front of said cylinders, a plurality of primary coils supported at the rear of said cylinders and having connections therewith, a flexible tubing supported above said cylinders, said tubing having one end secured in proximity to said 'coils and its 0 osite end dependin at the a PP 1 e front of said cylinders in proximity to said timer, a support for the depending end of said tubing, a connecting joint upon the depending end of said tubing, a plurality of wires incased within said tubing and connecting said coils with said connecting joint,

and a plurality of separated unincased wires connecting the wires of said joint with. said timer.

2. In a wiring system for combustion engines for motor vehicles, the combination with a plurality of engine cylinders, of a timer positioned at the front of said cylinders, a plurality of primary coils supported at the rear of said cylinders and having con nections therewith, a flexible tubing sup ported above said cylinders, said tubing having one end secured in proximity to said coils and having a plurality of spaced apertures therein, and its opposite end depending at the front of said cylinders in proximity to said timer, a forked member upon the front cylinder for supporting the depending In testimony whereof I have signed my v name to this specification in the presence of two subscribing witnesses.
