I TIMER TERNAL-GOMBUSTION ENGINES.
having an arm in which the ignition wires areflcollected and through which they are passed and connected at their inner ends to the contact segments, the arrangement being such that the distributer body may be rocked .back and forth to advance and retard the spark without the ignition wires being displaced or without any interference between "said wires and other adiacent parts of the machine,'thus obtaining a distributer body and timer which is certain in operation andf'reliable at all times.
With the above and other objects in view, the invention consists in the no'ml construction, combination and arrangement of parts. as herein described, illustrated and claimed. In the accompanying drawings :Figure 51 is an outside face view of the distributer body showing the relation of the same to the -gear case of an engine. Fig. 2 is an enlarged .inside face view of the distributer body.
A ,Fig. 3 is a detail longitudinal section of the -;-{revolving contact arm. Fig. 4 is a vertical --.{;1ongitudinal section through the distributer -jbody, showing one of the wires and its relation to the arm and body of the distributer. Fig. 5 is a longitudinal section throu h the distributer taken at right angles to Fig. 4:.
. Fig. 6 is a section on the line 66 of Fig.
4. Fig. 7 is a section taken on the same line as Fig. 6 showing the main bodv of the distributer formed in one piece. Fig. 8 is an' inside face view of the construction shown in Fig. 7, indicating by dotted lines the arrangement and location of the WlIB ';reoeiving passages. Referring to the drawings, in order to illustrate the application of the timer or distributer of this invention to an internal combustion engine, 1 represents what is known as the gear case usually arranged at 66 the front end of an engine as used in auto- Specifieation of Letters Patent.

Application filed April 26, 1915. Serial No. 23,916.
.mobile practice, 2 designating the crank shaft, 3 the oil receiving neck or funnel, 4 the closing cap therefor, and 5 the spring for holding the timer or distributer in place relatively to the end of the timer shaft (not shown), the spring 5 being pivotally mounted at 6 and the free end thereof being formed with an inwardly extending hemispherical projection 7 which is normally reoeived in a concaved pocket or recess 8 in the distributer body for the purpose of hold- .ing said body in its operative position, while permitting said body to be oscillated or partially turned to one side or the other by means of the operating connection 9 in order to advance and retard the spark.
In the preferred embodiment of this invention, the main body of the distributer is cylindrical in shape, said body being indicated generally at A and'comprising a main section 10, a channeled section 11 and a cupped section 12. The cylindrical body of the distributer as a whole is provided with a radially extending arm 13 through which i the ignition wires pass aswill hereinafter be described. The main section 10 is pro-- vided with a circular recess 14 to receive the adjacent face of the channeled section 11 and is also rabbeted as shown at 15 to I receive the correspondingly rabbeted periphery of the channeled section 11. The section 11 is also rabbeted at 1,6 to receive the reduced inner peripheral portion of the cupped section 10. The sections 10, 11 and 12 may be glued or cemented together or otherwise fastened together in fixed relation to each other.-
p The section 12 is provided with an internal flange 17 recessed to receive contact.
In order to make room for the heads of the screws 19 and the wires connected there to, the member 11 is provided with the annular channel 2). In its opposite face the member 11 is provided with another annu- 12: channel 21 to receive the wires 23, four of which are shown in Fig. 5, thus adapting the distributer'body'as illustrated in the accompanying drawings for use in connection with a four cylinder engine. By reference to Figs. 4 and 5 it Wlll be observed that the arm 13 is boredlength- Wise to form a series of substantially parallel passages 24 for the wires 23, said passages extending lengthwise of the arm 13 which may be of any desired length, preferably long enough asshown in Fig. 1 to extend above the gear case 1. Tubular ferrules 25 are inserted tightly in the outer ends of the passages 24 and around the wires 23 which are headed or expanded and flattened against the outer extremities of the ferrules as shown at 26. The usual jacks ,27 are adapted to he slipped over the plugs or stems formed by the ferrules 25 in the manner shown in Fig. 1, said jacks being fastened to the extremities of the ignition wires 28 leading to the spark plugs or other igniters of the engine.
28 designates a rotary contact arm having a sleeve like hub portion.29 which is fastened to the timer shaft (not shown). Adjacent to its extremity the arm 28 is formed with a socket 30 to, receive a slidable brush 31 usually formed of carbon, said brush being urged outwardly by means of a backing spring 32 which thereby operates tohold the extremity of the brush 31 always in contact with the adjacent face of the flange '17. and'the contact segments 18 hereinabove described.
Instead of forming the main body of the distributer in sections as above described,
the said body may be formed in one piece as shown at 33 in Fig. 7. In such case, relatively long screws 34 are employed to fasten the contact segments 35 to the internal shoulder or hearing face 36. Holes 37 are bored through thearm 38 of the distributer body, certain of said holes having angular portions 30 so that the wires when,
inserted through said holes may lead to their respective. contact segments 35. I Other holes 40 are bored at right angles to the holes 37 and 38 so as to enable the screws 38 to be inserted and also to enable the terminals of the wires 23 to be fastened to a After this is the heads of said screws; done, plugs 41 are driven into the holes 42 and the entire device given a coat of varnish or the like.
. It will of course be understood that the distributer including the main body thereof and the projecting arm, is composed of suitable insulating material such as fiber board or the like now in common use. 'In this way the wires, although each separately insulated as. shown at 42, are insulated from each other and kept absolutely separate as far as any electrical connection is concerned.
The chief advantage of the invention resides in the arm 13 and the relation "thereof to the cylindrical body of the timer and the timer shaft, it being a simple matter the engines now employed in Ford cars.
What I claim is:-
A distribut'er embodying a substantially cylindrical body of insulating material provided with a radially extending arm having inclosed wire receiving passages, said body comprising a main section formed integrally with said arm and also formed with a circular depression in one face thereof, another section seated in said depression and formed with an annular wire receiving channel in its inner face and also formed with an annular channel in its outer face, and also formed with a circular depression in its outer face, a contact section seated in the last named section and having a circular series of contacts inset therein in line with the channel in the outer face of the second section. and headed metal fasteners securing said contacts in place and having their heads arranged in the last named channel.
In testimony whereof I aflix my signature in presence of two witnesses.
