To all whom it may concern:
Be it known that I, ERNEST ALFRED W se, a subject of the King of En land, residing at Caversham, Reading, in ngland, have invented certain new and useful Improvements in Ignition and Lighting Systems for Internal-Combustion Engines, of which the following is a specification.
This inv(ention .relates to ignition and lighting systems for internal-combustion engines, and has for its object to so arrange the engine-shaft, motor-shaft (for lightin purposes), and the magneto-shaft, that the chain drive connecting these shafts may be adjusted by means of a single eccentric. The invention also has relation to an improved means for mounting the magneto and dynamo so that they are rigid with the engine-casing.
Various arrangements have been made for adjusting chain-drive in such systems, but according to this invention there is combined with the driving-shaft, dynamo-shaft, and magneto-shaft disposed parallel to each other but not all in the same plane, and chain-gearing connecting them together all on the same side of the engine, a bracket secured to the engine in such manner that it can be bodily adjusted parallel to itself in any direction and which bracket provides hearings on both sides of the chaln-drlve for that one of the three shafts previously mentioned which is intermediate of the other two, so that by adjustment of this bracket, its shaft can always be brought to a position to properly tighten the chains extending to the other two shafts.
Preferably the adjustable bracket in addition to its securing means, engages the engine through the medium of a cam-ring, so that when it is loosened itcan be adjusted to the desired position by the eccentric.
The invention further relates to other details all of which are hereinafter fully described with reference to the drawings and whereof the novel features are pointed out in the claims.
In the accompanying drawings which illustrate one method of carrying out this invention Figure 1 is a side elevation of an engine showing the chain-gearing casing, the dynamo and magneto mounted thereon;
Fig. 2 shows the chain-gearing and its casing on a largerscale and in section on the line 22 of Fig. 1 but with the coverplate removed, and
F 1g. 3 1s a section at right-angles to that off 1g. 2 on the bent line 3-3 of F ig'. 2, an
'Fig. 4 is a detail sectional view corresponding to part of Fig. 3 showing a modification.
The same letters indicate the same parts throughout the drawings.
The englne A has rigidly secured on it g at one end part of a casing B within which the ends of the engine-shaft C, dynamoshaft D,. and magneto-shaft E are housed. These shafts carry sprocket-wheels C, C 12, D*, E and are interconnected by chains 1*, F The engine-shaft is also interconnected by a chain F to the cam-shaft G. It Wlll be seen that all the sprocket-wheels for the shafts D and E, together with their chains are situated at one and the same side of the motor, and that although the shafts are parallel to each other they are not in thesame plane, so that it follows that the chalns F and F can alwaysbe properly adjusted by movement of the shaft D. To enable this movement to be made, the shaft D is carried in a bracket D which provides ball-bearings D and D for the shaft on opposite sides of the sprocket-wheels mounted on that shaft. The bracket is provided with side-openings to permit the passage of the chains F and F and has a flange D whereby it is secured to the casing B which is rigid with the engine. The holes D in the flange D to receive the fastening-bolts D are considerably larger than the bolts so that the bracket can be adjusted bodily parallel to itself in any direction on the fiat face of the casing To control this adjustment, the bracket is provided with a cylindrical stem D which is surrounded by a cam-ring D mounted to move angularly in a hole in the casing B. Any convenient means may be provided for operatin this cam-ring, and thus when the bolts 5 are slackened, the ring can be turned to move the bracket D and thus the shaft D to such position that the chains F, F are properly adjusted, and when this positionhas been found, the bolts D are tightened up and thus the shaft is held in the ad usted position. The whole gear is covered in by an outer plate B shown in Figs. 1 and 3.
It will be appreciated that to avoid a complicated connection between the shaft D and the dynamo H which it drives, the dynamo should be directly coupled to the shaft D and therefore the dynamo must move with any adjustment of the shaft. By arranging the casing B to project out from one side of the motor A, it provides a support upon which the dynamo can be carried. A bracket [H is mounted on the opposite side of the casing B to that occupied by the bracket D but is secured in place by the same bolts and is centered on the stem D of the bracket D so that as the bracket D is moved, the bracket H will be correspondingly adjusted. This bracket H is also provided with large holes in the parts engaged by the bolts D so that when the bolts are loosened they do not interfere with its adjustment.
If desired, a second cam ring D may be mounted within the cam ring D as shown in Fig. 4i, and these two cam rings may be independently adjustable. It will be appreciated that where two cam-rings are thus employed the shaft D can be moved into various positions which are not possible with the one cam-ring only. The cam-rings may of course be of any degree of eccentricity desired.
The magneto J and the dynamo H are both housed on the same side of the engine, as shown in Fig. 1, and lie behind the projecting portion of the casing B. The magneto is rigidly secured to the engine A, and the same is true of the dynamo through the .medium of the parts H and B. Both of these elements are on the non-valve-tappet' side of the engine, which in fact makes it possible to mount them rigidly on the engine, and thus vibration such as results when one or more of these elements is carried on a part not rigidly connected with the engine is avoided.
Although this rigid securing of these parts to the engine and the settin of the one element, namely the magnet, a ove the other, that is, the dynamo, is primarily intended to allow' for the adjustment of the chains F, F as already explained, yetit will be appreciated. that even apart from the question of chain-adjustment the construction has the advantage of rigidity referred to. 7
