Application filed July 31, 1913. Serial No. 782,389.

To all whom it may concern.

Be it known that I, JAooB D. KISER, a

citizen of the United States, residing at Elyrizuin thecounty of Lorain and State of Ohio, have'invented a new and useful Fuel-Atomizer, of which the following is a specification.

This invention relates to atomizers for liquid fuel such as used in connection with hydrocarbon engines, one of its objects being to provide a simple and efiicient structure of this type which can be applied readily to an engine and which has means whereby the amount of fuel supplied to the engine can be minutely regulated either prior to or during the operation of the engine so that complete combustion can be effected under all conditions.

Another object is to provide improved means for mixing the air and oil.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can. be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :-Figure'1 is an elevation of the atomizer, a portion of one of the adjusting elements being shown in section. Fig. 2 is a section through the device on line AB Fig. 1, the casing of the nozzle being shown in section so as to illustrate the controlling means therein in elevation. Fig. 3 is an enlarged central longitudinal section through the valve' mechanism ofthe nozzle, the central needle being shown in elevation. Fig. 1 is an enlarged section on line C-D Fig. 3. Fig. 5 is an enlarged section on line E;F Fig. 3. Fig. 6 is an enlarged section on line GH Fig. 3. Fig 7 is an enlarged section on line -J Fig. 3. Fig. 8 is an enlarged section on line KL Fig. 3. i

It is to be understood that the atomizer herein described can be adapted for use in connection with different types of hydrocarbon engines and, therefore, I do not desire to restrict myself to the particular mounting of the parts shown in the drawings.

In the drawings 1 designates a block adapted to be bolted or otherwise secured to the cylinder and from this block extends a nozzle casin 2 projecting through the head of the cylin er, a portion of which is shownat 3. Nozzle casing 2 has a bore 4 which extends into the block 1, the outer end of the bore being counter bored as at 5 while the inner end is tapered, as at 6, to a small outlet orifice 7. Arranged in the bore 4 is a.

valve the construction of which is shown more particularly in Figs. 3 to 8 inclusive. This valve includes a central tubular core 8, one end of which is externally screw threaded, as shown at 9. while its other end is provided with a frusto conical head: 10 having ports 11 at desired intervals, these ports diverging away from the adjacent end of the core 8.

A sleeve 12, is mounted for rotation on the core and abuts at one end against the annular shoulder13 formed by the inner end of head 10, this abutting end of the sleeve beingformed with an annular flange 14 in which are provided peripheral notches 15 spaced apart distances equal to the distances between the ports 11.

That end of sleeve 12 remote from flange to the sleeve by a collar 19 which is screwed onto the threaded end 9 of the sleeve 8 and is preferably externally screw threaded, as shown at 20. A set screw 21 may be provided for fastening the collar to .the sleeve 8.

' I A groove 22 is formed in the peripher of the ring 18 and has a pivot pin 23 exten ing thereacross, this pivot pin or screw pro ecting beyond the exposed face of ring 18 and into the ath of a stop arm 24; which projects radlall from the collar 19. Lugs 25 are located 1n the counter bore 17 and ex -tend from ring 18, these lugs fittin within V the notches 16 so that sleeve 12 an ring 18 are thus caused to rotate together as long as the ring is held in engagement with the sleeve by means of the collar 20.

Mounted u on the inner sleeve 12 is a small outer s eeve 26 having a conical end 27 which abuts against flange 14. This sleeve has an annular groove 28 and the periphery of the sleeve is provided at opposite sides of the groove with annular series of crossed rooves 29 communicating at their points of intersection and opening into the annular groove 28 and through the ends of thesleeve 26. Sleeve 26 is secured to the core 8 by means of a screw 30 'or the like 5 which extends through a slot 31 formed in the inner sleeve 12. This will be apparent by referring to Fig. 7. Thus it will be seen that when the core 8 is rotated the small outer sleeve 26 will move therewith, this movement relative to the inner sleeve 12 being limited by the screw coming against one or the other of the ends of slot 31. 0

Another larger outersleeve 32 is mounted 'for rotationofi the inner sleeve 12 and abuts 25 at one end against the small outer sleeve 26 while its other end is rovided with an annular flange 33 proviiled in its periphery with a groove 34. A pivot screw 35 or the like extends across the groove 34 and up- '30 wardly into a segmental recess 36 formed in the periphery of ring 18. The pivot screw 35 cooperating with the wall -of groove 36, serves to limit the relative rotation of sleeve32 and sleeve 12. v

Sleeve 32 is provided With a series of annular grooves 37 and formed in the outer surface of the sleeve between these grooves are annular series of crossed grooves 38 whichcomm'unicate and open into the an- 40 nular grooves 37. The end series of grooves- 38 nearest sleeve 26 discharge through the end of sleeve 32 so as to partly or entirely register with the rooves 29 formed in sleeve 26 or to. close t e' adjacent ends; of said 451grooves 29. j

r The sleeves 26 and 32 fit snugly within the casing 2 so that any fluid; in order to pars from one end to the other-of said casjug; must travel within the intersecting and 28 before enterin the notches 14 and ports 11 and then passing to the outlet 7,

The port 7 is adapted to be closed by means of a needle valve 39 slidably mounted; in the core'8 and adapted to .be operated by the valve mechanism ordinarily provided upon hydrocarbon engines .so that the port 7 will be opened atdesired intervals.

For the purpose of efieeting the'desired adjustment of the herein described, ad usting means such as shown particularly in Figs. -1 and 2 are provided. A rod 44 extends into the groove 22 and is "pivoted on pin 23, this rod 44 being adapted to slide wlthin a gland 45 whereby grooves 38 and 29 and across the grooves 37 parts, of the atomizer leakage is prevented. *A slot 46 is provided in the rod and projecting into this slot is the rounded end 47 of a lever 48. This lever is fulcrumed on a bracket 49 and can be provided with a handle 50 whereby the same can be manipulated readily. Furthermore astop screw -51 can be provided for limiting the swinging movement of the lever in one direction. It will be understood that by shifting lever 48 rod 44 can be moved inwardly or outwardly, thereby to cause the ring 18 to rotate. Sleeve 12 will also be rotated so as to move the notches 15 into or out of'register with the ports 11, thereby regulating the amount of fuel discharged into the outlet end of the casing 2. During this rotation of theinner sleeve, 12, the core 8 and the outer sleeve 26 will be held stationary by collar 19 which can be placed in engagement with any fixed structure. A'rod 40 extends into the groove 34 and is pivoted on the pin 35, this rod being mounted to slide in a gland 41 located in the block 1. The outer end portion of the rodis screw threaded and is engaged by an adjusting nut 42 held against movement toward or from the block 1 by holding bracket43. Obviously by rotating 'the nut, rod 40 can be shifted inwardly or outwardly relative to block 1 so as thus to rotate flange 33 and outer sleeve 32 and to and bring the end series of grooves 38 into or out of register with the adjacent series ,of grooves 29.

It willbe seen that when a mixture of air and oil is admitted to the space between sleeve 32 and casing 2 it can only pass to the outlet port 7 after traveling through the intersecting grooves 38 and 29. By shifting sleeve 32 relative to sleeve 26, in the manner hereinbefore described, communication between the grooves '38 and 29 can be partly or entirely cut off thus regulating the amount of fuel supplied to the port 7.

Obviously as the, air and hydrocarbon supplied to thespace between sleeve 32 and easing 2 are caused to flow along the intersecting grooves 38 and 29, they will become thoroughly commingled and, when the needle valve 39 is shifted to open position, the explosive mixture will be sprayed through the ports 11 and 7, the said mixture being broken up into such small. particles that ignition can be efi'ected readily and completely. Importance isattached to the e'fiected while the. engine is in operation, this adjustment being so minute that any predetermined quantity of fuel found necessary to produce the best results can be directed into the cylinder. Not only can the amount of mixture supplied to the ports 11 be regulated by the relative movement of the parts 26 and 32, but the size of the jets discharged through the ports ll can be regumove the said sleeve relative to sleeve 26 *fact that the adjustment of the parts can be lated by the relative adjustment of the parts a an outlet, a core stationary within the casing and having ports converging toward said outlet, a needle valve Within the core for closing the outlet, and means revoluble upon the core for controlling the admission of fuel to the portsfrom the interior of the casing, said adjusting means including a slidable rod, means for shifting said rod, and means operated by the rod and having spaces normally regist-eringwi'th the ports.
