ENGINE-STARTER.

Application filed December 12, 1910.` Serial No. 596,771.

To all 'whom imag concern 1 lie it known that I ,Lnoivaiui L. MCLAR'ri', i a-citizen of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in`Engine-Starters, of

use on automobiles, and the invention con- `The invent-ion relates particularly to that stributing or "timing valve operin'ders Where the" pressure on the piston pressed. fluid is, aportion of the,` burned gases of the cylinders, means being employed-to keep the .pressure 3ina storage tible fluid under Vpressure may be used.y A handor equivalently operated valve controls the supply' of"press'ure from the storage Inhthe accon'ipanymg drawings I have shown a preferred form of my invention as applied to a six cylinder engine; but `it any number of cylinders.

In the drawings: Figure` 1 is aside elevation of a typical six cylinderlautomobile" engine equipped with my invention. Fig.l 2 is an enlarged-cross section taken on line 2 of Fig. 1. Fig. 3 is a section taken on line 3-3 of Fig. 1. Fig. 4 is a section taken on line 4.- of Fig. 1. Fig. 5 is a section showin a modified connection of the timing valve to the rotating parts of the engine.

Referring now to the drawings 5 designates the casing of a typical six cylinder engine and 6 the respective cylinders. At some point on the casing I provide a special gear housing 7 in which are incased gears 8'rotatively connecting half time cam shaft timing valve is rotated at' the same speed as the half time shaft, it being designed to feed the compressed gas to each of the six cylinders during every two revolutions of crank shaft 11. This' method connection is merely typical of other forms.

In Fig. 5 I have shown the connection of the distributing valve to the electric timer or distributer shaft. In this case the construction of the valve is modified to allow the passage of th`e shaft completely therethrough. This method of connection will suggest others applicable to machines of various designs.

The timing valve consists -ofa casing 13 inclosing a-cone shaped valve 14 which is fitted with aground joint in the casing and held in place by nuts 15. Valve stem` 16 is hollow, a longitudinal duct 17 leading from its outer Iend to a point central within valve valve into tight seating engagement with4 -the casing but allowing it to revolve freely.

The otherend of Valve stem 16 passes into a stuiiing box 20 in a casting 21. Passage 22 in casting 21 connects with the longitudinal lduct in valve stem 16 means being provided at`23 for theconnection of a pipe for the supply of gas under pressure. Casing '13 is provided with a plurality of ports 25, in this rase being six innumber, arranged around valve 14y `and adapted to be registered by passageway y18 at different times during the rotation' of the valve. Ports 25 are connected'to passages 26 which are adapted for connection with pipes or tubes leading to the various cylinders of the engine. In the arrangement shown it will be noted that, with the valve rotating in the direction indicated, gas under pressure will be fed to passages 26 in direct order'beginning with the uppermost and endingwith the lowermost in Fig. 2. But the cylinders on anautomobile engine are usually exploded in a sequence different from their arrangement on the crank case. For A'the resent.

have assumed that, counting the cylinders from the front or left hand endin Fig. 1, the cylinders are exploded in the following manner; `one` four, two, six, three, vfive. rI`he pipes leading from passages 26 are consequently arranged to feed gas under ressure to the cylinders in the above name y"sequence. Gas under pressure is taken from `LEONARD L. MCLARTY, OF LOS ANGELES'. CALIFORNIA, `ASSIZGNOR OF ONE-HALF TO `the cylinders in any well 'known manner,

mechanisms 30 allowing a certain amount of*y exploded gases to pass through pipe 31 to storage tank 32. From the storage tank 32 a pipe 33 leads to hand valve 34H. This valve may be operated in any desired manner by the driver of the car. From valve 34 a pipe 35 leads to the timing valve and connects at 23. From each of passages -26 a tube or pipe 36 leads to an appropriate cylinder. The

relative arrangement of the valve, connecthe end .of stem 16 vis prolonged through casting 21, yas indicated yin dott-ed lines in Fig. 3, and the timer shaft 40 continued up from the stem. This connection of the valve is preferable on many engines on'acdount of economy of installation, and especially Where my starting system is applied to the engine afterv building. When applied at the time of engine construction, the valve may be placed in the most convenient. position and the structure of the engine altered to suit. l

I-Iaving described my invention, I-claim:
