TIMER FOR ENGINES.
Specification of Letters Patent.
Application filed January 3, 1919. Serial No. 269,406.
To all whom it may concern Be it known that I, Lro H. WHELAN, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invent d certain new and useful Improvements in Timers for Engines, of which the following is a specification.
This invention relates to internal c0mbustion engines, and especially to the ignition systems thereof; and the object of the same is to produce an improved timer for use particularly on Ford cars.
()ne object is to increase theraccessibility of parts so that the repairs and adjustments can be readily made.
' Other objects will appear in the following specification and claims. In the drawings Figure l is an elevation of a portion of a Ford car showing the position of the timer.
Fig. 2 is an enlarged front elevation of the timer itself.
Fig. 3 is a section on the line 3-3 of Fig. 2.
Fig. 4 is an elevation from the inside of the cap of the timer showing the fiber cup.
As is well known, the timer for an ordinary internal combustion engine comprises a: rotating element or brush mounted on an appropriate shaft which is the front end of the cam shaft in the Ford machine; and
a relatively fixed although slightly adjustadvance or retard able element bearing several points with which the brush makes contact successively and from which lead wires to the spark plugs. The present invention contemplates no change in the rotating element or brushand therefore the same is not illustrated.
The timer herein comprises a hollow element or shell 1 whose inner portion constitutes a substantially cylindrical body 2 and whose outer portion is dome-shaped or nearly conical, being open at 3 to receive the nose 4 of an elbow 5 which is held removably in said opening by a spring (3 indicated in Fig. 1. Projecting radially from or secured to one side of the cap is an ear 7 to which is attached a rod which leads through suitable connections to a hand lever within reach of the driver, whereb the entire shell and its (xmtents may be a justed around its axis to the spark as well understood. I have not thought it necessary'to show the wires, except the cable 8 in Fig. 1, but it will be clear that this cable leads in through the elbow of Fig. 3 and turns downwires-of this cable.
ward through its nose into the interior of the cap 1, and the Wall of the latter is r0- vided with four inside grooves 9 for the our Inside the cap is placed a which is shown in section in Fig. 3 but omitted in Fig. 4, and this cup has four holes 19 at proper points to register with the grooves 9 so that the several wires of the cable may pass therethrough. Otherwise the cup prevents the escape of grease or whhtever the packing used within the timer and. through the elbow or through the space between the nose and the wall of the opening 3. Within the cylindrical body 2 of the timer is placed a fiber ring 12 indicated in black in Fig. 4 and provided with notches at four points for the plates 13 constituting the heads of the points, which plates are curved slightly as shown in white in Fig. 4 and have their faces struck on the same curve as the inner face of the fiber ring 12. The stem 1% of each point leads radially outward through the fiber ring, thence through an insulating bushing 15 which is seated in a hole in the body 2, and finally receives a nut 16 at its outer extremit Each are from the cable is led down one of the. Tomes 9 through one of the holes 19, and is connec with the stem of the point just beneath its head or plate 13; whereas appropriate connection is made from the single wire to the brush (not shown) which rotates within the cylindrical body portion 2 and makes contact with the several plates 13. I
The brush being mounted on the forward end of the shaft, it is obvious that in order to gain access to the interior of this timer, it is only necessary to remove or turn aside the spring 6 and withdraw the elbow 5 which slips along the cable 8 so that its nose 4 comes out of the openin now nothing hol mg the shell in it can be readily removed, especially if the rod is unhooked from the ear 7 or permitted to flex. Assuming-that the shell and its contents are drawn shell can be turned aside to give access to the interior for cleaning or repair. Also as soon as the shell and its contents are removed, the brush and its arts are exposed for cleaning and repair. Xfter having received proper attention, the parts are restored by a reversal of this operation and without the necessity for tools. Thus it will be seen that I have produced a timer which is extremely place, and

The foregoing'description and the drawings have reference to what may be considpedient and-fall within the having a cylindrical with an opening at its apex, the inner wall the body having ered the preferred or approved form of my invention. it 1s to be understoodthat I may I body'and a conical cap of said cap being grooved toward the openholes opposite said grooves, a series of points whose stems are mounted through said holes and insulated from the body, and a fiber cup within said shell and having holes opposite said grooves;
