GAS AND OIL ENGINE.

SPECIFICATION forming part of Letters Patent No. 788,748, dated May 2, 1905.

Application filed December 6,1900. Serial No. 38,855.

To all whom it 'mf/,ty concern:

Be it known that LAUeUs'r F. BAUnrnof Kansas Oity, in the county of Jackson, in the State of Missouri, have invented certain new and useful Improvements in Gas and Oil Engines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specilication.

My invention relates to improvements in gas and oil engines; and my invention consists in certain featu res of novelty hereinafter described, and pointed out in the claims.

Figure 1 represents a side elevation of a gasv or oil engine embodying my invention. Fig. 2 represents a plan view of the same. Fig. 3 represents an end view of the same, showing in particular the vaporizing and mixing' chamber and the supply-valve and its controlling mechanism. Fig. 4 represents a cross-section ot' the cylinder-head and its connected parts. Fig. 5 represents a detail view ot the mechanism controlling the supply-valve. Fig. 6 rcpresents a detail view of the mechanism controlling the admission of oil to the vaporizingchamber and controlling the speed of the engine. Fig. 7 represents a detail view ot' the yoke and mechanism controlling the action of the oil-supply valve. Fig. 8 is a cross-section view taken on the dotted line a I) ot' Fig. 6. Fig. 9 is a cross-section taken on the dotted line c d of Fig. 6. Fig. 1G is a side elevation view of the governor-weights and parts connected thereto. Fig. 11 is a horizontal sectional view taken on the dotted line ef ot' Fig. 10. Fig. 12 is a cross-section taken on the dotted line g /r of Fig. 10.

Similar numerals refer to similar parts throughout the `several views. n

1 represents the base, on which the engine and its operative parts are mounted.

2 represents the cylinder, and 8 the cylinder-head secured upon the cylinder by the bolts t through the bolt-holes 5 of the cylinder-head, the spaces 6 in the cylinder-head corresponding with like spaces in the cylinder and forming a continuous water-jacket therefor.

Vithin the cylinder-head are seated the valve-casing 7 ofthe exhaust-valve, communieating with the exhaust-port 8 of the cylinderhead, and the valve-casing 9 of the admissionvalve, communicating with the inlet-port 1() olE the cylinder-head. Said valvecasings are secured in position by bolts through the flanges 11.

ln the valve-casing 9 is `formed the valveseat 12, on which is seated the admissionvalve 13, the valve-stem 111 of which, extending beyondtlie casing, has mounted upon it a tension-spring 15, arranged to be compressed between the cap 16 and the casing 9 upon the olgiening oi the valve, and the tension or' the spring being such that the suction generated by the outstroke of the piston will open the valve against the tension of the spring and admit the charge, as will be more fully set out hereinafter.

Upon the casing 7 is formed the valve-seat 17, upon which is seated the exhaust-valve 18, the valve-stein 19 ot' which, extending beyond the casing, has mounted upon it a tension-spring 20, the tension of this spring being such that'the valve will not be operated by the suction of the outstroke of the piston, but requires the positive action ot' an exhaustlever 21, operated by a cam 22 upon the governor-shat` t 23, to open the valve to permit the exhaust at the proper time.

Communicating with the inlet-port ol the cylinder is a vaporizing and mixing chamber 24, to which the oil is admitted through an oil-duct 25, (shown in Fig. 4,) communicating with a supply-duct 26, and the supply of oil admitted being controlled and regulated by the valve 27, having its seat in a valve-seat 28, surrounding said duct. A marginal lip 29 is formed adjacent to said duct, over which the oil admitted from the duct when the valve is opened will spread, and `thus facilitate the vaporization. The valve-stem 3() of valve 27 extends through an extension 31, formed on the casing ot' the mixing-chamber 2st, and is provided with a head 32, operating in a recess 33 in said extension, and in said recess is arranged a tension-spring 3ft, bearing against said head and tending to keep said valve open. On said extension 31 is lixedly mounted a yoke (See Fig. 3.) 1n said yoke, between the set-bolts 36, is mounted a head.-

shown in Figs. 5 and 6, and on the axle of said disk and bearing against the hub thereof is a tension-spring 43. Said diskd 42 rides normally upon the head 44 of the governorshaft 23, but at certain times engages the beveled-edgedV disk 45, eccentrically mounted in said head 44, and when such engagement takes place by the slightest contact of the beveled edges they will be drawn into further engagements by the yielding of the spring 43, when lateral movement of the arm would be stopped by the set-bolt 46 lin the lug 47 on the head-block 37 engaging the side of the yoke. Said feed-arm extends directly over said oil-supply valve and is provided with an antifriction ball-bearing upon the head 32 of the valve-stem. A spring 49 is connected with said feed-arm and with a stationary or fixed portion of the engine, as with a 'hook 50 upon the vaporiZing-chamber, the relation being such that said spring has a lateral as well as a downward pull upon said feed-bar, and the spring 49 being' stronger than the spring 34 the valve will be held closed by the action of theformer until by the engagement of the disk 42 with the governor-disk 45 said feed-arm is raised, and then by the action of the spring 34 said valve will be opened and a supply of oil admitted to the vaporiZing-chamber.

To regulate the engagement of the disk on the feed-bar with the eccentricdisk on the governor-shaft, I provide as follows: On opposite sides of the governor-shaft are arranged the governor-weights 51, formed to fit closely upon and around the shaft and connected by the S-shapedv arms encircling the shaft and pivotally mounted thereon, whereby when at rest the weights are adapted to lie close upon the shaft, and hence close upon the center of axis, and the weights lying thus close as may be to the axis of revolution are much more susceptible to the action of centrifugal force, giving' a much more delicate governing effect by reason of such shape and arrangement. With said governing-weights is connected a sliding sleeve 52, to which motion is given along the axis by the movementof the weights. A transverse rod 61 extends through a hole in the shaft 23. The threaded ends of the rod 61 have mounted thereon, respectively, two externally-threaded tubular members 62, the inner ends of which are tapered to fit corresponding recesses in opposite sides of the governor-shaft 23. The S-shaped arms connecting the weights 51 are provided each with 'a charge admitted t0 the engine.

a transverse threaded hole, in which is fitted the adjacent member 621 Lock-nuts 63 are mounted one on each end of the rod 61 and bear, respectively, upon the outer ends of the members 62. In opposite sides of the sleeve 52 are provided longitudinal slots 64, in which kare respectively mounted the members 62.

On opposite sides of the sleeve 52 are provided lateral projections 65, adapted to be struck by the S-shaped arms of the weights 51, and thereby move the sleeve 52 lengthwise in one direction on the shaft 23 when the weights 51 are outwardly swung by centrifugal force due to rotation of the weights 51 and shaft 23. The members 62 and nuts 63 may be so adjusted on the rod 61 that the inner conical ends of the members 62 may touch without binding on the shaft 23, thus effecting a verysensitive governing mechanism, which permits free swinging of the weights 51.

In the path of said sleeve is extended one arm,

53,0f a rocking lever, pivotally'mounted upon a bracket 54 upon the side of the engine, said arm being provided with an antifriction-roller 55, bearing against the end of said sleeve. In the other arm, 56, of said rocking lever is provided a set-screw 57, adapted to `bear against the lateral spur 39 of the head-block 37, in which is mounted the feed-bar 41. In a bracket 58 upon the engine is mounted a set-screw 59, which `bears upon a ltensionvspring 60, which in turn bears upon said arm v56 of theigoverning-lever, the pressure of said spring upon said lever-arm being regu: lated by said set-screw, and thereby the action of the governing mechanism regulated to a very great'nicety.

Now if the engine is running slowly, sothat at each revolution of the governor-shaft the disk on the head ofsaid shaft will Vengage the disk'on the feed -bar and the valve opened, admitting a supply of oil to the mixing-chamber, and a charge will be admitted and an explosion take place with every cyclethat is, at every two revolutions of the pistonand the speed of the engine will be increased. Under this increase in speed of the engine and consequent accelerated speed of the governor shaft theA governor weights will be thrown outwardly, causing the sleeve to move the lever-arm 53, which movement of leverarm 53 will move lever-arm 56 against the pressure of the spring 60 and by the setscrew 57 bearing against the spur 39 on headblock37 will carry the feed-arm laterally until the disk thereon will no longer engage the disk on the governor-shaft head and the feedarm will hold the valve closed, and the supply being cut off no further charge will be admitted and no further explosion take place. Then as the speed slackens the governor-weights will fall until the disks again come into engagement and the supply-valve is opened and By setting the set-screw 59 the tension of the spring 60 IOS IIO
