Application filed January 10, 1 894.

Be it known that L WALTER F. VAN GUYS- LING, of the city and county of'Albany, in the State of New York, have invented new To all whnm; it may concern.-

and useful Improvements in Automatic Lu bricators, of which the following is a specification.

\My invention relates to a-device for lubri eating movingparts of machinery and is cplo erated by said machinery in such manner thata constant and predetermined quantity of lubrlcant will be positively applied to the machinery in a given time, and it consists of the construction herein'describ ed and pointed ,out in the claims forming part of this specification.

In the accompanying drawings, which are 1 herein referred to and form part of this specification, Figure 1 .is a front elevation of my 2, lubrica'tor, showing the preferred manner of operating the moving .mechanism when ap plied to a locomotive.v Fig. 2 is a side elevation of my lubricator. Fig. 3 is a longitudinal section of the same. Fig. 4 isa plan view,

- and. Fig. 5 is an enlarged and detached detail of a device for automatically stopping the operation of the lubricator when the supply of lubricant is exhausted from the apparatus. As representedinthe drawings, A designates a plate which forms a support for the operative parts of my lubricator, and which carries one or more lubricant-cylinders, B, but preferably, two of said-cylinders are provided for the reason that they divide the strain on 3 5 the operating parts more evenly. Each of 5 1 said cylinders is provided with a stuffing-box,r

1, of any well-known form, and is fitted to re-' ceive a plunger 0, which, for the. purpose of securing the least weight with sufficient 40 strength, is formed oflight metallic tubing with the inner end closed to prevent the flow of lubricant into the bore of the plunger. Said'plungers are attached to a cross-head, D, in any suitable manner. Each cylinder B is provided with a fillinghole provided with a screw-plug, 2, or other suitable closure, and from each feeding-hole, or other suitable part of a cylinder, a-lubricant-pipe, 3, leads to any point where the lubricant is to 0 be applied.

E designatesa yoke formed on, or attached,-

moving outward.

serial No. 496,360. or model.)

to the cross-head D and provided withascrewthreaded nut, 4, into which a feed-screw, 5,

is fitted to revolve and efiect the required, I

movements of the plungers C. To the outer end of said feed-screw a ratchet-wheel, 6, is secured so as to bear against the outer face of the plate A and preventan inwardmovement of the feed-screw,.and a collar,'7, on

said feed-screw, bears against the inner'face of said plate and prevents the feed-screw from A, handle, 8, fixed in the ratchet-wheel 6 affords the means for turning the feed-screw by hand when occasion requires. F designates a second ratchet wheel provided-with a shaft or pivots, 9, journaled in the plate A and in a bracket, 10, secured to said plate. A bell-crank, G, is fitted to vibrate on the shaft 9, and an arm, 11, of said bell crank is provided with a pawl, 12, that is fitted to engage with. the teeth of the ratchet-wheel F andimpart an intermittent rotary motion to .the latter. Said pawl is provided with a lat erly-projecting finger, .13, for a purpose shortly explained, In the outer end of the shaft 9, astud or pin,'14, is'arranged eccentrically to thecenter of said shaft and is provided with a pawl, 15,- that is fitted to engage with the teeth of the ratchet-wheel 6 insuch manner that an intermittent rotary motion will be imparted to the feed-screw 5to eflect the inward stroke of the plungers'G." A check: pawl,-'-1 6 shown in dotted lines on Fig. 1-'

.is arranged to engage with the teeth of the ratchet-wheel F, so as to prevent a retrograde movement of the latter.

H designates an automatic-tripper engaging the paw1 12 from the teeth of the ratchet-wheel F. As shown in the drawings,

for dis:

said tripper consists of a lever, 17, arranged to vibrate on a pivot, 18, and provided with a weight, 19, that will normally depress that end of the lever. The opposite end of the latter has a convex guard, 20, which, when the weighted end of said lever is depressed, will engage with the finger 13 and raise the pawl 12, thereby disengaging the latter from the teeth of the ratchet-wheel F, and such disengagement will continue until the tripper is restored to a position to allow the pawl 12 to reengage with the teeth of the ratchet-wheel F- A detent, ,21,'is loosely pivoted to the lever 17 andlis'p'rovidedwith a pendent'-weight,22, that will normally tend to swing the detent 21 into a depressed position, where it will en 5 gage with a shoulder, 23, of the bracket 10, or other adjacent part, and retain-the lever 17 in an elevated position, as shown in Fig. 2;

whereby the guard 20 will be depressed and allow the 'pawl 12 to engage with the teeth of the ratchet-wheel A stop, 24, prevents the weighted end of the lever 1'7 from being depressed below a point requ-ired' to bring the guard 20 to its proper elevation to efizect the'disehgage'ment of the pawl 12 from the ratchet-wheel F.

adapted to engage with the pendent 22 and effect thedisengagement of the arm 21 from --theshoulder 23, thereby allowing the lever- 2o that is loosely pivoted to the pendent arm of.

the bell-crankQG, and is arranged to have its periphery bear constantly against the periphcry 'of the shaft I, so that said disk, by its frictional contact with the shaft, will acquire a corresponding number of revolutions. from said shaft. The eccentricity of the disk- 28 will impart a vibratory motion tothe bellcrank '26, and the number of vibrations 'of said bell-crank will correspond to the number of revolutions of theshaft I, provided said .shaft and disk are of the same diameter,

"and it is obvious that, by increasing thediam-- eter .of the disk 28,- in respect tothe diam-.'

eter of the shaft I, the number of vibrations of the bell-crank 26 will be correspondingly reduced-from the number of revolutions of said shaft, and that, by reducing the diam-' 'eter of-the disk 28, so that it will be less than that of said shaft, the number of vibrations of said bell-crank will be increased in the ratio that the diameter of the shaft I- bears to the diameter of said disk. By this arrangement provision is "made for either increasing or 'diminishingthe number of vibramay require.' Y Alateral' arm, 2 0f the bell-crank 26 is connected--by"a rod, 30 to a similar arm,

31, of the vbell-crank G, so that'a correspond- 1 ing motion will be imparted'to the latter. I Preferably the arm .31 is provided with a slotted opening, 32, so that the position of a wrist-pin; 33, can be adj usted, in relation to '3 tsj distance thecenter of the. shaft 9, so

An arm, 25, attached ,to the yoke E, is

. receive a vibratory motion. take against the teethofthe ratchetfwheel ions ofthe bell-cranks G. and26' as occasion theltraveref the-pawl 12, on the ratchet-wheel F, and, consequently, produce a greater or lesser number of revolutions ot' said ratchet-wheel fora given number of vibrations of the bell-crank G. By this arrangement, the shaft Ican be revolved-in either directionwhich is absolutely necessary, in

locomotive engines, and-other classes of machinry-withOut affecting the proper work-' ing 'of the device, for the vibrations of the lever Gwill then be eifected in the manner. I

just described. 1

I do notconfine myself to the means herein described for imparting a vibratory motion to the bell-crank G, for the reason that such.

motion-can be obtained from'an'y vibratile or revoluble part of a machine, and I. do not limit myself to themanner, herein described for disengaging the pawl '12 from the ratchetwheel F, as any means for automatically ef- Tecting that result will be equally good for the purpose.

- My inventionoperates in the following manner: The apparatus-being erected in place and the bell-crank G- connected to a moving part of the machinery in such manner that a proper vibratory movement will be imparted to said bell-crank, and the lubricant-pipes 3 being connected to the parts to, be lubricated,

the pawl is disengaged from the teeth of the ratchet-wheel 6 and the feed-screw 5 rotated, by means of the handle 8, to move the 'pluugers C to the extremity of their'outward stroke. The cylinders B arefilled with lubricant through thefilling-holes and the latter are closed by the screw-plugs 2. When -.the.machinery, to which my lubricatoris attached, is set in motion, thebell-erank G will Its pawl.12 will F and impart an intermittent rotary motion 'to the latter and to the shaft 9, which carries said ratchet-wheel, and each' revolution of said shaft will impelthe pawl15 toniov'e the ratchet-wheel 6 a partial revolution that will equal one or more teeth of the latter, accord-v ing to-the eccentricityof the stud 14 in the shaft 9. By this movement of the ratchetwheel 6 a corresponding movement will be imparted tothe. feed-screw 51 to force the plungers Cinto the cylindersB to a distance proportionate to th'ep'itcli-"of the thread of the feed-screwmultiplied by the fraction of a revolution imparted to said feed-screw, that v is to say, if the pitch of the feed-screw is one{ tenth of an inch and said feed-screw receives one-twentieth of a revolution by each revoadvanced one two-hundreth of an inch during-the. same, time, and acorresponding lution oftheshaft 9, the plungers C will be quantity of lubricant will be positively ejected plungers.' When the plungers C are near the end-of their inw'ard stroke, the ar'm25 willtake against the pendant 22 to= etfect the disengagement ,of. the. arm 21 from the shoulder m the cylinders at each advance of said '23 'saidarm passing over the upper end of a the shoulder-allowing the weighted end of the lever 17. to suddenly fall to its depressed position and raising the guard 20 to efiect the disengagement of the pawl 12 from the teeth of the ratchet-wheel F, thereby automatically stopping the operation of the lubricator. After the cylinders B have been refilled, in the manner herein described, and

the several parts restored to their proper places, the apparatus will be in condition for a repetition of the operation just described. What I claim as my invention, and desire to secure by Letters Patent, is

1. An automatic lubricator consisting of a lubricant-cylinder, a plunger-fitted to slide in said cylinder, a feed-screw arranged to move said plunger, a ratchet-wheel secured to said feed-screw, a second ratchet-wheel arranged to rotate independently of said feedscrew, and provided with a pawl that is eccentrically attached to its shaft; said pawl being arranged to engage with the ratchetwheel of the feed-screw, and avibratile-lever provided with a pawl fitted to engage with said second ratchet-wheel, substantially as specified.

2. In an automatic lubricator, the combination. oflubricant-cylinders, plungers arranged to slide in said cylinders and connected to across-head provided with a yoke carrying a screw-threaded nut, a feed-screw fitted to engage in said nut, a ratchet-wheel secured to said feed-screw, a second ratchetwheel arranged to rotate independently of the feed-screw, a vibratile-lever provided with a pawl fitted to engage with the second ratchet-wheel, a pawl eccentrically connected with the second ratchet-wheel and arranged to engage with the ratchet-wheel of said feedscrew, and an automatic tripping-devicesubstantially as specified-for disengaging the plunger-moving mechanism, as and for the purpose specified.
