LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 554,429, dated February 11, 1896.

Application filed Tune 19, 1895. Serial No. 553,305. (No model.)

To all whom t may concern:

Beit known that I, WALTER F. VAN GUYS- LING, of Albany, in the county of Albany and State of New York, have invented new and useful Improvements in Automatic Lubricators, of which the following is a full and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in that class of lubricators which are operated automatically by the machine to which the lubricator is applied and by which a certain quantityn of the lubricant will be positively applied to the part of themachine which the device is designed to lubricate; and it consists of a stationary piston, a removable lubricant-cup fitted to move upwardly on said piston, and mechanism for automatically effecting the upward movement of said cup to force the lubricant therefrom, as herein set forth.

In the accompanying drawings, Figure 1 is a side elevation of my invention; Fig. 2, a front elevati on,with the stationary piston and part of the lubricant-cup shown in vertical section. Fig. 3 is a rear elevation of the device; Fig. 4, a plan view. Figs. 5 and 6 are respectively horizontal sections of Fig. 1 at the lines X X and Y Y 5 Fig. '7, a vert-ical scction at the line Z Z on Fig. 1; Fig. S, a vertical section of Fig. 5 at the lineW W; Fig. 9, a detached rear elevation ofthe friction-clutch wheel; and Fig. 10 is a rear elevation, on a reduced scale, of the arm and lever for operating the friction-clutch wheel.

As represented in the drawings, A designates the bracket or frame which carries the operative mechanism of my apparatus. Said bracket is preferably made of two corresponding parts, which are joined vertically and are secured together by bolts 1, and each part is provided with a vertical groove 2, which is preferably made V-shaped, so that when the two parts are joined together said grooves will form a guide, for a purpose shortly eX- plained. A foot 3 is formed on each partof the bracket for the purpose of securing the apparatus in position; but the form and position of said foot may be varied to suit the position in which the apparatus is to be placed. The upper end of the bracket is provided with a boss 4, in which a feed-screw B is tted to rotate.

O is a movable carrier that is provided with a head 5, in which the feed-screw B engages to move said carrier in a vertical direction. Said head and its pendant G are fitted to slide in the grooves 2 of the bracket A. The carrier O has a shelf D, formed on a horizontal plane, and semicircular sides 7, which connect the shelf D to head 5. A groove 8 is formed at the lower part of the sides 7, at'the upper side of the shelf D, so as to afford a hold of the lubricant-cup, as hereinafter described.

E is a stationary piston which is secured to an arm 9, projecting from the forward side of the bracket A. Said piston is provided with a tubular stem 10, which connects with the arm 9, and to said stem a pipe 11 is connected to form a communication vwith the bore of the stem 10, so as to convey the lubricant to the point where it is to be applied. The lower end of the stem 10 has its bore enlarged, and a screw-thread 12 is cut in such enlargement. A circular flange 13, whose lower face is flush with the lower end of the tubular stem, is formed on the latter to form the head of the stationary piston. A follower 14, provided with a tubular stem 15, iitted to screw into the screw-thread 12, has a check-valve 16, arranged to stop a backiiow of the lubricant from the pipe 11 when the lubricant-cup is removed from the carrier O or when the latter is moved downward preparatory to refilling the lubricant-cup. A cupped packing F is interposed between the flange 13 and the upper face of the follower 14E, and the latter is preferably provided with an annular rib 17, which by being pressed into the packing F prevents the latter from being laterally displaced. The packing F is preferably made of leather and has a flange 1S extending downwardly therefrom, and when the pressure is applied to the lubricant said iiange will be pressed outward to form a close joint with the bore of the lubricant-cup.

G is the lubricant-cup, preferably made of drawn metallic tubing, having an open top, j whichis slightly iiared, as at 19, and a closed bottom. The lower end of the perimeter of said lubricant-cup is provided with a circum- IOO -concentric to the center of said wheel.

ferential rib 20, which is fitted to engage with the groove 8 of the carrier C, so that when the latter is moved downward the lubricantcup G will not be raised from the shelf D by reason of a vacuum being formed in the lubricant-cup when the latter is moving downward.

His a ratchet-wheel whose teeth are formed on its lower face, which is secured to the upper end of the feed-screw B for the purpose of imparting a rotary motion to the latter to effect an upward movement of the carrier C and its superimposed lubricant-cup G, in order to force the lubricant, in required quantity, from the lubricant-cup G, and thence through the pipe ll to the part of the machine to which the lubricant is to be applied. For the purpose of turning the feed-screw B by hand the ratchet-wheel II is provided with a handle 2l, that is arranged eccentrically to the center of said feed-screw.

I is a friction-clutch wheel whose perimeter is preferably formed with a V-shaped edge 22, and one of the iiat faces of said wheel-the side nearer the bracket A-has a hub I,having the form of a volute, so as to form a shoulder 23, formed on a radial line. The opposite face of the wheel I has a circular recess 24, that is The wheel I is arranged to rotate intermittently on a fixed stud 25, secured in the bracket A. The stud 25 is provided with a collar 26, which is integral with said stud and has a plane face that bears against the outer face of the wheel I to secure the latter in place on said stud, and the perimeter of said collar is formed eccentrically to the center of the stud 25.

A segmental plate 27, whose outer edge is formed to fit the concavity of the wall of the recess 24 and whose inner edge iits the perimeter of the collar 26, lies loosely in said recess and is arranged so that when the wheel I is turned in the proper direction said plate will present no resistance to the motion of said wheel, but on reversing the direction of movement of the wheel I the plate 27 will be clamped between the wall of the recess 2-L and the perimeter of the collar 26, thereby positively preventing a backward movement of the wheel I. The segmental plate 27 is retained in position in the recess 24 by the hub of the arm K. A bell-crank J is pivoted on a stud 28, secured in the bracket A, and the lower arm of said bell-crank is arranged to bear against the perimeter of the hub I, so as to allow the free end of a pawl 29, that is carried by the upper arm of the bell-crank J, to engage in the teeth of the ratchet-wheel II and effect a slight movement of the ratchetwheel with each impulse of the wheel I when the latter hasicompleted a revolution, so that the lower arm of the bell-crank J, by passing the shoulder 23, will bear against the smaller part of the hub I', and thereby the upper arm of the bell-crank will fall back to allow the end of the pawl 29 to engage with the next succeeding tooth of theratchet-wheel H. The

pawl 29 is loosely pivoted to the upper arm of the bell-crank J, and at its outer end said pawl has a shoulder 30, which when the parts are in position to effect the feeding of the lubricant will engage with a gravity-arm 3l to lock the pawl 29 and gravity-arm together as one piece and hold the inner end of the pawl 29 in engagement with the teeth of the ratchetwheel I-I.

The hub of the gravity-arm 3l is provided with a slotted opening 32, that lits on a flattened portion of a pivot 33, which is loosely tted in the upper arm of the bell-crank J and which carries the gravity-arm 3l. The slotted opening 32 is long enough to allow the gravity-arm to be moved back sufficiently to disengage the latter from the shoulder 30, thereby allowing the pawl 29 to swingdownward to disengage itself from the teeth of the ratchet-wheel II.

In order to effect an automatic disengagement of the pawl 29 from the teeth of the ratchet-wheel II, to stop the discharge of the lubricant from the lubricator, an arm 34 is pivoted to the bracketA to lie in the path of the carrier C. The head 5 of said carrier will, take against a pin 35 or other part or attachment of the arm 34E, and thereby cause the free end of the latter to swing upward. On the free end of the arm 34E an inclined face 3G is formed, and by the upward movement of said arm the face 36 is carried into contact with the end of an arm 37, which forms part of the gravity-arm 3l, and by the continued upward movement of the arm 34 the gravityarm will be pushed outward and disengaged from the shoulder 30, thereby effecting a releasement of the pawl 29 and allowing the latter to swing downward and become released from its engagement with the teeth of the ratchet-wheel I-I.

An arm K is loosely pivoted to the xed stud 25, and is provided with a mortise in which an adjustable arm 33 is tted to slide endwise in order to allow the end of said arm, to which power is applied, to be adjusted closer to and farther from the center of the stud 25 to vary the degree of movement of each impulse of the feed-screw B to effect the required discharge of the lubricant to suit the requirements of the machine to which the lubricator is applied.

To the outer end of the arm K a frictionpawl 41 is pivoted on a pivot 40, and is provided with a V-shaped notch 42, or other conformation, formed to lit the periphery of the wheel I. The arm K can be changed in its position in respect to the wheel I so as to adapt the apparatus for receiving its motion with the arm 3S arranged in a vertical position, as shown in Figs. 1 and 3, or with said arm arranged in a horizontal position, as shown in Fig. 9, but to make such changes in the arrangement of the arm 3S the arm K is shifted to bring different sides of it next to the wheel I, and the pawl 4:1 must be shifted correspondingly. A spring 43 is attached to IOO the pivot 40 and is fitted to bear upon the upperface of the friction-pawl 41 and press the latter into frictional contact with the periphery of the Wheel I.

My invention operates in the following manner: The adjustable arm 38 having been adjusted to the proper length to produce the requisite movement lof the friction-clutch Wheel I to feed a proper quantity of the lubricant in a given time, and the end of said arm being connected to a moving part of the machine which this apparatus is to lubricate, so as to impart a vibratory movement to the arm 3S, the lubricant-cup G having been filled With lubricant and placed upon the shelf D of the carrier C, the gravity-arm 31 is moved into position to engage With the shoulder 30 and hold the end of the paWl 29 in engagement with one of the teeth of the ratchet-Wheel I'I, thereby limparting an intermittent rotatory motion to the feed-screWB to effect an upward movement of the lubricantcup G on the stationary piston E. By this movement of the lubricant-.cup on the stationary piston the lubricant will be gradually forced from the lubricant-cup and compelled to pass through the pipe 11 to be discharged at the point to belubricated. IfVhen the lubricant is properly exhausted from the lubricantcup, the gravity-arm 31 Will be automatically disconnected from the paWl 29, in the manner hereinbefore described, to stop the feeding movement of the screw B, and the latter will be turned to move the carrier C downward sufficiently to allow the lubricant-cup G to be removed from the carrier C to be recharged With lubricant, after Which said cup can be replaced in position and the gravityarm 31 re-engaged With the pawl 29, thereby allowing the apparatus to resume its function.
