oAs, o|| OR SIMILAR MOTOR-ENGINE.

SPECIFICATION forming part of Letters Patent No. 526,369, dated September 25, 1894. Application filed March 13, 1894- Serial No. 503,505. (No model.) Patented in England November 17, 1892,1lo. 208,031.

To all whom it may concern:

-Be it known that we, HENRY HERBERT AN- nEEW and ALFRED ROWE BELLAMY, subjects the igniting tube to allow the surplus of air to? escape at starting and to Shift away the products of combustion confined in the tube after the firing of each charge. One drawback to this arrangement is that when the tube is changed the snifting valve and its connections have also to be displaced. One of the objects of our invention is to obviate this disadvantage by placing the snifting valve in close proximity to, but not in immediate connection with theignition tube", so that this latter can be removed and changed as often as necessary wlthont disturbing the valve and connections.

To render our invention perfectly clear we Wlll now refer to the accompanying drawing which is mainly a sectional view of the parts {otwhich our invention more particularly rea es. I i

The end of the cylinder is indicated by a. The valve for admitting the explosive mixture is marked b the exhaust valve 0; and the timing or ignition valve cl. All of these valves are operated by levers and cams from the side shaft e in the usual manner, that being no part of our present invention.

Within the chimney f is the burner g, and the ignition tube h, below which is a short tube t in commnnicationxwith a small chamber j, the exit from which into the atmosphere is controlled by a shifting valve 70. This valve is, which may be a mushroom valve as shown 01' any other suitable type of valve, is opened at or about the same time as the ignition valve 01 by means of a washer or projection Zcarried by the spindle of the ignition valve d which comes in contact with a tumbler catch m pivoted to the end of the spindle of the shifting valve k. The edge of the tumbler catch mis beveled and a kicking plate 01 is fixed to the frame so that when the spindle of the valve It has been moved acertain distance, the catch m is tilted by the plate n and the valve is is left free to be closed.

When the timing or ignition valve (1 is opened, the explosive fluid mixture flows through the short tube 2', ignition tube hand chamberj, and as the snifting valve is also opened at this time by means of the washerl and tumbler catch m as described, some of the gases escape through into the atmosphere until the explosive fluid mixture becomes ignited and the consequent increase of pressure caused by the expansion of gases closes the shifting valve It. When the ignition valve d is again opened the washer or projection lon its spindle will open the snifting valve 70 and allow some of the fluid mixture or products of combustion to escape through it into the atmosphere. In certain cases it may be found advantageous to allow the snifting valve is to remain constantly operative in combination with the ordinary timing or ignition valve d as described. When this is not the case the tumbler catch m can be turned back into the position indicated by dotted lines,after the engine has been properly started whereby the said valve remains closed and inoperative.

Instead of the Washer or projection Z and the pivoted tumbler catch m, any other suitable in communication with the ignition tube and opening at or about the same time as the ignition valve for the purpose of allowing the contents of the ignition tube to escape into the atmosphere, and a disengaging device i all arranged and operating substantially as 10 adapted to open the shifting valve, and allow described and as shown. it to be closed automatically, substantially as In witness whereof we have hereunto set our described. hands in presence of two witnesses.
