ALFRED ROWE 'BELLAMY, OF STOCKPORT, ENGLAND.

INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed April 3, 1907. Serial No. 366,143.

To ctZZ whom zit may concern.

Be it known that I, ALFRED RowE BEL- LAMY, a subject of Great Britain, residing at F ordsburg, Edgeley, Stockport, in the county of Chester, England, engineer, have invented new and useful Improvements in or Connected with Internal-Combustion Engines, of which the following is a specification.

My invention has reference to internal combustion engines and relates to means for controlling the lift of the valve by which more or less gas or explosive mixture is admitted to the engine cylinder.

The mechanism I have invented for this purpose is illustrated in the accompanying two sheets of drawings in which:

Figure 1 shows in end view, partly in section, so much of 'an internal combustion engine as is necessary to illustrate my invention. Fig. 2 is a view at right-angles thereto, and Figs. 3 to 5 are detail views.

In the accompanying drawings A represents the governor, which is of the usual or well-known type, and to the rocking shaft a thereof I secure a rod 1) to which is attached a projection or part 0 having a wedge shaped or inclined surface (1. The part c is shown in plan viewin Figs. 3,4 and 5. The tripper le verf carrying the blade 6 is carried as usual on a stud by the plunger f actuated by the pivoted lever e from the side shaft '6 in the ordinary manner. I arrange that the tripper blade 6 shall bear by means of a spring g, or it might be a load, against such inclined surface at. The motion of the governor rocking shaft a im arts movement to the part 0 having the inc ined surface (I, and when such inclined surface is thus moved, the tripper blade 6, being constantly maintained against the incline by the spring or load, is turned on its pivot and necessarily varies its direction of movement to some degree with relation to the stem h whereby the gas or charging valve i is actuated. In the drawings (Fig. 2) it will be seen that the stem h operates the gas valve i through the medium of a bell-crank lever i. I provide the stem h actuating the gas valve, or other valve which it is desired to operate, with a stepped contact piece 7' the various steps receding from the point of the tripper blade as shown clearly in Figs. 1, 3 and 4;.

As will be understood the nearer the step to the tripper blade 6 with which the blade be opened and the longer maintained open to i admit the gas or charge of explosive mixture. Such a stepped contact piece j working in conjunction with a tripper blade, I do not however claim to be new, the essential novel feature of my invention being to arrange that the tripper blade shall always be held in contact with an inclined surface such as (Z actuated through the governor rocking shaft.

At the maximum load on the engine the part c with inclined surface (1 is moved by the governor rocking shaft a to turn the tr pper lever on its fulcrum so as to direct the tripper blade 6 against the step on the gas or other valve stem nearest to the tripper blade and so open the valve for the maximum period of time. This is shown by Figs. 3 and 3* of the drawings. On a diminishing load the tripper blade comes into contact with the next step, as shown in Fig. 1, the position of the part 0 relative to the tripper blade being as indicated in plan view in Fig. 5, and so on from a maximum to a minimum, or to an en tire miss of the stem 7i as shown in Figs. 4 and 4 when the gas or other valve is not to be opened as will be understood.

Figs. 3 and 43 show in plan view the tripper blade e and the wedge shaped part c.

An important advantage of my invention lies in the fact that the variable lift of the gas or other valve is effected by a comparatively light strain on the governor, as the only work to be done is the sliding of the part 0 pro vided with the wedge or inclined surface cl against the spring actuated or loaded tripper blade 6. The friction of these parts may also be reduced by providing a rounded contact surface on the tripper blade 6 as illustrated, or'in other convenient ways. Thus it is not necessary to provide a special strong heavy governor, but the light governor usually employed with combustion engines is suflicient for the requirements.

I declare that what I claim is. 1. In internal combustion engines a rod 6 connected to the rock-shaft of the governor, apart 0 attached to such rod and formed with an inclined surface, a tripper blade and means to maintain such. tripper blade against the inclined surface substantially as described.
