- duits for protecting and supporting the elec- 4 trical conductors of an ignition system such as employed with internal combustion engines. My invention contemplates the provision of a pairof cooperating members forming halves of a tube or conduit through which the electrical conductors pass. -One of the halves in the preferred form of my invention is provided with a plurality of outlet openings through which the free ends of the electrical conductors may pass to their respective spark plugs of the engine. In use the conductors are brought together and the free ends of the conductors are brought through the openings provided in one of the conduit members, after which the other conduit member is fitted into the first member to inclose the conductors. Suitable caps are provided for each end of the mani- Fig. 2 is a fragmentary elevational View of one side of the ignition manifold;

showing the opening which permits the admission of the conductors; and

Fig. 4 is an enlarged sectional detail view of the device taken on the line 4-4.- of Fig. 2.

The drawing Fig. 1 illustrates a six cylinler automobile engine 9 having spark plugs 10 to 15 inclusive, each connected with an associated engine cylinder for igniting the charge within the cylinder. At 17 Ihave shown a distributor of conventional type having conductors leading to the spark.

plugs. The conductors are connected at one end to the contacts of the distributor, and have free ends 18 to 23 inclusive. The conductors pass from the distributer '17 through the ignition manifold 25 supported by suitable clamping members 26 and 27 attached to the engine frame. The manifold 25 comprises two halves 28 and 29 and as shown most clearly in Figs. 2 and 4, the member 28 is enlarged from a semi-circular cross section, as shown at 30 and 31, to admit the member 29,which is also semi-circular on cross section. The member'28 is provided with outlets 33 one for each spark plug, and in order to protect the conductors extending through the outlets I have found it desirable to form the material surrounding the outlets with a rounded portion 34 to prevent the wear which would result from having a sharp edge surrounding the outlets. To retain the members.28 and 29 in closed ositioncaps are provided for each end 0 the manifold, and the cap 37 for the inlet end of the manifold is provided with an opening 38 large enough to admit the wires'from the distributer. f desired, the cap 39 at the opposite end of the manifold may be provided' with an opening through which a conductor may extend. In assembling and attaching the device the conductors are brought together and the cap 37 is slipped over the wires to a point near the distributer. The section 28 is then brought adjacent the conductors and the free ends thereof 18 to 23 inclusive are inserted through the openings 33 and connected to their respective spark plugs. The member 29 is then inserted between the flanged portions 30 and 31 of the member 28. The caps 37 and 39 are then slipped over the ends of the manifold, which holds the two sections in aclosed position. The entire device will be supported by the clamping members 26 and 27 and the conductors will be protected and supported in the desired position.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United- States is:

1. In combination with an automobile engine having anignition system, an ignition manifold comprising two halves, one of said halves adapted to fit with the other of said an inlet opening for said conductors, a cap for each end of said manifold, one of said halves being provided with branch open ings, and means adjacent said openings to prevent chafing of the conductors".

2. A manifold for internal combustion engines comprising two cooperating members together forminga tube, means for retaining said members in position with respect to each other, one of said cooperating members being provided with 'a pluralitypf outlets, the material adjacent said outlets being rounded to prevent chafing of the conductor passing through the outlet.

3. An ignition manifold for internal combustion engines, comprising a pair of sections forming a longitudinally split conduit for receiving the distributing conductors,

one section of said conduit being provided with outlet openings, and means detachably securing the sections of said conduit together.

4:. A manifold for the distributing conductors of an internal combustion engine, comprising a conduit longitudinally split into a pair of sections, theed es of one section of said conduit being 0 set to receive the edges of the other section, one of said sections being provided with a plurality of outlet openings, and means for detachably securing the sections of said conduit together. a

In witness whereof, I hereunto subscribe my name this 8rd day of J une, 1918.
