Specification of Letters Patent.

Patented sept. 2,1919.

Application led. February 9, 1918. Serial No. 216,208.

To all 'u1/0m t may concern:

Be it known that I, VINCENP. MCVOY, a citizen of the United States, residing` at Mobile, in the county of Mobile and State of Alabama, have invented certain nevvl and useful Improvement in Lubricators, of which the following is a specification.

This invention relatos to lubricators and it has for its objects among'others to provide an improved construction of lubricator which, vvhile adapted for gravity feed in the usual manner under certain conditions, is designed primarily to be automatic, that is capable of being so set that the feed shall be uniform and at a predetermined rate of speed and quantity, normally beyond the control of the engineer, and in no Wise affected by variation of pressure in the steam pipe, that is, with the automatic attachment the feed will be the same under heavy throttle pressure as under no pressure, hence, the feed Will be the same Whether the engine be drifting or running under steam pressure.

The present invention has for a further object to provide means which shall insure against hand manipulation of the valves by the engineer or other person to `increase the feed, Without detection. The construction, however, is such that should from any cause the automatic feature `become inoperative, the operator may break a seal and thus give him control of the feed until the automatic attachment is again put in order, when the same is sealed against manipulation of parts to increase the feed beyond a predetermined quantity. l

I employ a turbine operated by steam from the boiler through the lubricator, which turbine, in turn, operates a pump for delivering the oil to the different feeds and from thence into the cylinders by Way of usual connections. The How of oil through the different feeds is governed by the pump and the latter is governed by the speed of the turbine. For this purpose, I employ a governor Which can be set for various speeds, as may be required, to deliver any desired number of drops to the different feeds, and the iioiv of steam to this turbine is controlled by a valve and when the latter is closed the device may be caused to feed by gravity b v means of by-pass valves in the pump. The arrangement is such, however, that should occasion require the flow of oil in one or more feeds may be by gravity, even While the pump is running. This latter, of course, necessitates thebreaking of the seal hereinbefore referred to. The ley-pass valve for the air pump feed is at all times accessible to the operator, vvhether the device be running under automatic or gravity feed, not heilig under the seal.

The present invention has for a further object to provide means for automatically insuring proper distribution of the oil to the valves, as Well as to the cylinders. As is Well known, under ordinary conditions the oil intended for both the `valves and the cylinders `fed into the same from the lubricator is( not equally distributed, that is, a por tion of the oil intended for the valves passes to the cylinders by reason of unequal pressure, the connections to the cylinders being open to the atmosphere one-half the time, while those to the valves are not. Nati rally, the oil talres the easier course, that is, to the cylinders. By the employment of check valves, I overcome this objection and insure the proper amount of oil going to the valves instead of a portion thereof to the cylinders. The before-mentioned check valves prevent the back flow of the oil to the boiler through the steam pipe of the lubricator, and under excessive pressure the check valve is seated so as to guard against this back flow of oil.

I may, sometimes, employ in connection with my present improvement means for facilitating or boosting the flow by commingling a supplemental flow of steam with the oil, such as shown in a prior patent issued to me, but` this is not absolutely essential in connection With the novel features above outlined.

The pump employed is of novel construction, `being valveless except for by-passes which may or may not be employed. The pump is geared to the turbine shaft and the parts so timed as to perform their functions positively and reliably, whether the device be Working under boiler pressure or void of pressure.

By my present improvement, instead of the operator being obliged to shut off each and every feed manually and separately, as is common, I provide means vvhereby all feeds are simultaneously shut off by manipulation of a single valve, which latter controls the liovv of steam. to the turbine. The opening ofV this valve to its. fullest extent, however, will not allow delivery of a greater quantity of oil than that` for which the governor of the turbine is set. Y

Other objects and advantages of the invention will hereinafter appear and the novel features theree-f will be particularly pointed out in the appended claims.

1n the present instance, l have shown what, at the present time, I consider the preferable embodiment of my invention, but it is evident that the same is subject to changes, variations and modifications in form, detailsof construction, proportions of parts, etc., without departing from the spirit of the invention or sacrificing any of its advantages. l, therefore, do not intend to restrict myself to the precise construction, proportion of parts, etc., herein disclosed, but reserve the right to make such changes, variations and modifications as come properly within the scope of the appended claims.

The preferred form of embodiment of my invention is clearly illustrated in the acceuipanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure l is a front elevation of a lubricator constructed in accordance with my invention. y

vLike numerals of reference indicate like parts throughout the several views.

My improved lubricator as herein illustrated and now to be described is designed to be attached in any suitable way to the boiler or other fixed portion of the lubricator or other engine. One lconvenient form of means of attaching or supporting the lubricator is seen in FigsQ and Sin the form of lugs or the likek 1. It is evident, however, that the lubricator may be attached in any other well known Way.

2 is the reservoir or body port-ion of the lubricator provided with the usual peep sight 3 for a well known purpose, at being the lill-A ing plug, also of known construction.

5 is the drain valve for draining the 7atei' from the reservoir 2, as is usual in this class of devices.

6 are the sight feeds or pee) glasses, of which there may be any desired number according to conditions under which the lubricator is to be used, in the present instance shown as five in number merely for the purpose of illustration. 7 are regulating valves for the sight feeds, operable by hand sngl y in the usual way, but when my automatic mechanism now to be described is in operation these valves are capable of being turned to diminish the iow of oil, but cannot be turned fto increase the flow of oil beyond an amount predetermined by the adjustment of the governor in the turbine, as will soon be made clear.

8 are pipes extending one from each valve chamber 9 of the sight feeds G to a pump, soon to be described, and through which the oil is pumped by said pump into the sight feeds 6. 10 is the feed or intake pipe for oil from the reservoir to the pump.

11 is a condenser provided with a coupling 12 or any suitable means for containing a strainer and one 'member, as 13, designed for connection with a source of steam supply, as with the steam space of the boiler,

the other end being closed by a plug, as shown at 12 in Figs. 1 and 2. 14 is a pipe connecting this condenser with the lower portion of the reservoir 2, as seen best in F ig. 3, so as to convey the water of condensation to the lower portion of the reservoir beneath the oil therein. 15 is a handoperated valve by which the flow of steam through the condenser is permitted, or slmtoif for the purpose of refilling the lubricator.

16 is a hand-operated valve for controlling the flow of steam from the boiler through the condenser 11 into the passage 17 in the upper portion of the reservoir 2, as seen in Fig. 3. From this passage or chamber 17, there extends a passage 1S, as seen best in Fig. 3, beneath a check valve 19 which controls a passage 20 down one side of the body portion of reservoir 2, as seen in Fig. 3, this passage communicating with a chamber 21, as clearly seen in Fig. 3. Leading from this chamber 21 is a passage 22 through a nipple or the like 23 designed for connection in the usual way with the part to be lubricated.

2f is a. steam pipe provided with a valve 25 and this pipe is connected with the steam space of the boiler or other suitable source of steam supply and with the manifold 2G, as seen clearly in Figs. 9. and 3. From this manifold there extend, in the present instance, four connections Q7, as seen in Figs.

2 and 3. In each of these connections 27 is Va check valve 28, as seen clearly in Fig. 3,

which controls a passage 29 from the ber 50 to the passage 22.

From the chamber 21 extends a passage 31 through a partition 32 in the body portion 2 of the reservoir and this passage 31 communicates by the vertical passage 33 with the corresponding peep glass 6, as seen clearly in Fig. 3.

At one end of the reservoir or body porf tion 2 of the lubricator, I support in any suitable manner a casing or chamber 34 Within which is a turbine `35 carried by a shaft 36 mounted in suitable bearings for free movement, carrying at one end a Worm 37, as seen in Fig. 3, Which meshes with a Worm gear 33 on a shaft 39 `mounted in a suitable bearing or casing 40, as seen` best in Fig. l, which shaft 39 carries at its upper end a Worm 41 meshing with a Worm gear 42 on the pump shaft 43, as Will be clearly understood upon reference to Fig. 3. 44 is the end bearing for the shaft 39, the same being removable and adjustable and de signed to carry the end thrust, as Will be readily understood.

45 is the pump cylinder secured in any suitable manner to the body 2 of the lubricator. In the present instance, I have chosen to show the pump cylinder as provided ivith lugs or the like 46, as seen in Fig. l, to receive the screws or the like 47 for this purpose.

48 is a packing gland about the shaft 43 Within a casing or chamber 49, as seen best in Fig. 6. i

50 is the end member of thevstufiing box or gland and this further constitutes the end of the pump cylinder, the other end 5l, as seen in Fig. 6, being removable and adapted to form a support for the adjacent end of the crank shaft 52 of the pump. The opposite end member 50 is `also removable and between the same and the collar 53, rigid with the shaft 43, is an end thrust roller or ball 'bearing 54, as seen clearly in Fig. 6. The shaft 43 revolves, but the shaft 52 is fixed or relatively stationary,but With the shaft 43 there revolves the pump body or plunger 55 which is interlocked at its end With the adjacent end of the shaft 43 in any suitable or convenient manner.

The crank shaft 52 fits the bore of the cylinder or casing 45 except at predetermined` points throughout its length Where the diameter of the said shaft 52 is reduced, as seen at. 56, see Fig. 8. These reduced portions 56 constitute cranks and there are as many of these cranks in the shaft 52 as there are feeds to the lubricator. Corresponding in position with each of these cranks the pump casing 45 is provided with nipples or the like 57, screwthreaded, as at 58, for the attachment of the pipes 8. At

champoints diametrically opposite the bores or passages of the nipples or the like 57, the Wall of the casing 45 is provided with passages or the like 59, as seen in Fig. 6, which communicate with a chamber 60 extending substantially the full length of the pump and the outer Wall of this chamber is provided With Suitable means, as 6l, for connection of the intake pipe 10 which connects, as at 62, seeJ Fig. 1, with vthe reservoir 2 of the lubricator.

The rotating member 55 of the pump `is provided With the peripheral substantially semtoircular grooves or

passages

63 and 64, the grooves or passages 63 connnunicating at the top With the passages59 liereinbefore referred to, and the passages 64 comn'iunieating at the bottom. with the downwardly extended passages 65 which communicate, by means of the passages 66 in the couplings 67, with the pipes 8, as will be readily understood upon reference to Figs. 4 and 1.

The pump casing 45 is provided at the rear With extensions 68, as seen clearly in Figs. 4 and 5, and in each of theseextensions is the upper substantially horizontal passage 69 communicating with the chamber 60 and this-passage 69, in turn, communicates with the vertical passage 70, the lower end of Which commimicates, by means of the substantially horizontal passage 71, with the passage 65 just described, all as clearly illustrated in Fig. 4.

l/Vithin each extension 63, at the junction of the

passages

69 and 70,`isa seat for a check valve 72, see Fig. 4, 73 being a spring acting to normally seat the valve, and the extension or stem 74 of this check, when the check is seated, terminates slightly above the end portion 75 of a stem 7 6, which end portion traverses the passage and is provided with a cam portion 77, as seen clearly in Fig, 4. When this stem 7 6 is turned by means of its thumb nut or the like 7S, the' cam portion. 77 lifts the check 72 from its seat. When the stem is turned back to its normal position, the spring 73 seats the valve, the cam portion 77 being moved away from the adjacent end of the stem, all of which Will be clearly understood upon reference to Fig. 4. The stem 76 passes through a stufling-box 79 on the extension 68, for an obvious purpose.

These details, howevcrfas well as many others, pertaining to the construction, may be varied as occasion may require, so long as the same function and result are attained. The particular construction of turbine employed is not .essenti al `and the present invern tion is not restricted in thisrespect, either' in the parti-cular form of turbine or the particular construction of the governor soon to be described. y

The member 45, through which the shaft 52 passes, is provided with alternate parti tions and chambers and between each two partitions works o-ne of the reciprocatory plungersV of the pump. In the drawings, these partitions are indicated by the reference numeral and are seen best in Fig. 6. The chambers between these partitions are indicated by the numeral 81. In each of these chambers works one of the plungers. As these plungers are all alike, a detailed description of lone will suilice for all. In Fig. 7 there is shown an enlarged detail view of one of such plungers 82 which is in the form of Ia cylinder hollow for a portion of its length, the lower end being closed, as shown at 83 in Figs. 4 and 7, and the upper end internally threaded, as at 84, for the reception of a screw-threaded plug 85, see Fig. 4, projecting` from the lower end of which is a portion 86 extended beyond the threads` as seen in Fig. 4:, and designed for contact by a cam 56 of the cam shaft 52, whereby the plunger is reciprooated back and forth by the action of the cam 56, as the member 55 revolves, carrying the plungers therewith, the result being` substantially the same as if the cam sha-ft revolved and the member 55 remained stationary, but by the construction clearance space at the diametrically Opposil e` end or point, as seen clearly in Fig. 4.

89 is a pipe leading from the steam portion of the reservoir 2 and connected at 90 to the governor valve which is located within the chamber 91 at the end of the turbinefcasing 34. This governor may be of any well-known type adapted to the purpose. In the present instance, I have chosen to show a form of governor which I have found eflicient and which serves its purpose most satisfactorily. This governor in detail is illustrated in Fig. 10, to which attention is now directed. This governor valves comprises a valve member 92 reciprocating within the casing 93 and, in alinement therewith, is a pin 94 for loose reciprocation in the upper end of the casing 91 with its lower end resting upon a fiat surface 95 on the curved lever 96 pivotally mounted, as a-t 97, within the casing` 91 and its free end bearing against a. pin 98 mounted to reciprocate loose within the member 99 and at all times under the control of the governor balls or weights 100 pivotally mounted, as at 101, upon some part fixed to and movable with the turbine wheel 35, as shown in said Fig. 10. 102 is aspring acting in opposition to the governor weights, the construction being such that as the speed of the turbine increases, centrifugal force throws the weights out, moving the pin 98 in the direction of the arrow in Fig. 10, moving the lever 96 in the direction of the arrow connected therewith and forcing the governor valve 92 in the direction of the arrow thereon in said Fig. 10, shutting oif the steam proportionately.

In order that the device may be so set that manipulation of the valves 7 by the engineer or operator cannot, by any possibility, increase the amount of oil to be fed to the engine, I provide a seal or lock for the wheels 78 which control the check valves 72. This seal or lock may be of any desired character. In the present instance, I have chosen to show the wheels 7S as provided with openings 103, through which may be passed a wire or the like 104; which may be sealed by any well-known form of seal, as at 105. The central valve, however, is not included in the seal. The two valve wheels at the right are thus connected and sealed and the two on the left are likewise sealed. The middle one, however, is left unsealed in order that this, which is the air pump feed, may have the sam/e pressure in its steam at all times as the same is not controlled by hand throttle. Under ordinary conditions, these valves are locked and sealed, so that they cannot 'be manipulated by the engineer or operator; but, should, perchance, anything go wrong with the automatic mechanism hereinbefore described, the engineer or operator, by breaking the seal, can convert the lubricator into the ordinary gravity feed until the necessary repairs are made.

Also, in order to guard against removal of the plugs 106, which permit access to the check valves 72, from being removed to remove the valves 72 and overcome the necessity of breaking the seals, I lock all of these plugs by means of a wire seal 107, as seen clearly in Fig. 1, which wire is passed through openings 108 in all of the said plugs, including the middle one, and then sealed in any well-known or desired way.

With the parts constructed and arranged substantially as hereinbefore described, the operation, briefly stated, is substantially as follows:

The parts being operatively coluuu'ted with the steam space of the boiler and the various connections being made as hereinbefore described and as illustrated. and steam being admitted from the boiler or other suitable source of steam supply, through the strainer at 12 and into the condenser 11, and the valve 15 being open, steam or the water of condensation is admitted through the pipe 1l into the bottom part of the reservoir 2 beneath the oil therein, as will be readily understood upon reference to Fig. B. The valve 1G aise must be opened. Steam is then admitted to the turw bine through the pipe 89 by turning the` tion is imparted to the shaft 43. The shaft 43 being coupled up with the rotary pump member 55, the latter is rotated with the shaft 13, the shaft 52 with its cams 56 remaining stationary as hereinbefore described, and not revolving, the plungers 82 are reciprocated back and forth, it being understood that the plungers are arranged notall in parallel alinement with but disposed about the member 55 so as to extend at different angles for operation to supply oil at different times to the various feeds. Furthermore, this arrangement relieves the turbine of its load, as all of the plungers are not discharging against pressure at the same time, some intalring and others discharging, as will be readily understood. So long as these conditions exist, the `oil is automatically fed to the feeds 6 through the pipes 8 and from thence through the passages 33 and 31, the chamber 21 and passage 22 to the part to be lubricated. The `flow of oil" through each feed takes place in the same way. The valve 16 being open, steam passing down through the condenser enters the passage 17 which is common to all of the feeds andpassing through the passage 18,

under the check 19, and opening the saine,

flows downward through the passage 20 into the chamber 21 in greater quantities than can escape through the choke bore in the inner end of the coupling 23, thus creating pressure on both sides 0f the oil, these pressures being practically balanced, or, possihly, slightly infavor of the gravity feed, thus insuring practically uniform feed.

In order to boost or facilitate or rush the flow of oil after it enters the passage 22 in the coupling 23 on its way to the part to be lubricated, steam is admitted to the pipes 24 by opening the valves 25 and this steam then passes into the manifold 26, lifting the` check valves 28 from their seats, and then the steam Hows through the passage 29 and through the openings in the coupling 23 into the passage 22 and, commingling with the oil, hastens the flow thereof.` It will be understood, of course, that the pipe leading from the coupling 23 to the engine or the parts toA be lubricated is of considerable length, generally from twenty to twenty-five feet, and this boosting of the `oil is of material advantage. These check valves 28 serve to prevent back How of the steam from one feed to another through the passage 29.

As constructed. with the valve handles 78 locked and,V sealed and the plugs 106 also beingsecured and sealed, there is no way for the engineer or operator to manipulate any of the parts to increase the feed. The valves 7 may be manipulated to decrease the flow of oil through any one or more of the feeds, butnot to increase it; Should, however, from any cause, the lubricator fail to work in the manner just described, the engineer. or operator is authorized to break the seals 105, when the hand wheels 78 may be turned so as to reverse `their positions and allow the lubricator to "work as i a gravity feed lubricator until the necessary repairs are made. For convenience, the hand wheels 78 are provided with some suitable indicia, such, for instance, as P2-indicating pumpL-and Gr-indicating gravity, so that the operator can tell at a glance whether these valves are set for the gravity or automatic or pump feed. VVhenthe valve stems 78 are turned from their automatic or pumping position to that for` gravity feed, the valves 72 which, under automatic feed are seated, are lifted from their seats by the cams 75, as will be readily understood upon reference to Fig. 4.

The seal 107 is supposed never to be broken unless it becomes necessary to remove the plugs 106 for repairs or some other purpose. If this seal is broken, the valves 72 might `be tampered with and this it is essential to guardagainst.`

The speed of the turbine and the consequent speed of the pump and feed of the oil is controlled by the governor mechanism shown in Fig. 10, a heavier spring 102 being employed for greater speed and a lighter spring for less speed.

lt will be apparent that each plunger 82 of: the pump is provided with an opening` 82?, as seen 'clearly in Fig. 7, through which the openings on the crank shaft 52 pass.` See also Fig. 6 in which all` of the plungers are` shown. i
