To all whom it may concern.-

Be itknown that I, EZRA F.. WITTER, a citizen of the United States, residing at Milford Centre, Union county, Ohio, have invented certain new and useful Improvements in Lubricators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appert-ains to make and use the same.

My invention relates to the constructio and arrangement of automatic valves for 1ubricators, and has for its object to provide means which will effectually exclude all foreign substances from the lubricators and bearings in combination with which they are employed. i

Broadly considered my invention consists of a perforated flexible disk applied to the inlet or exit opening of a lubricator, the elasticity of the disk keeping the perforation normally closed but allowing it to be opened for the admission of the lubricant. v

I will first describe my invention with reference to the accompanying drawings and then `more particularly point out in the claims what I deem as new therein.

In said drawings:-Figure I is a side elevation of an oil can having myimprovements tional view of an oil can and lubricator cup having myimprovements attached, the parts Fig. III is a perspective view of the oil can nozzle and attachments, all of the parts being detached from their normal positions. Fig. IIIa is a modified form of nozzle attachment. Fig. IV

normal or closed position. Fig. V is a similar view showing the nozzle protruding. Fig. VI is a perspective view of the perforated plate for supporting the automatic valve `on the nozzle. Fig. VII is a plan view of the yoke. Fig. VIII is a plan View of one form of my improved lubricator cup. Figs. VIIIa and VIII" are detail views showing the preferredV form of mylubricator cup. Fig. IX is a sition of the screw cap, carrying the flexible disk, to the end of the nozzle.

Similar letters of reference indicate the same parts throughout the several views.

I have shown my invention as applied to the nozzle of an oil can, and also as applied to the ordinary form of oil cup such as is used for bicycle bearings.

A is the oil can, having the customary internally screw threaded neck B formed integral therewith. l

C is the nozzle provided with an externally screw-threaded base c adapted to engage in the neck B, and a iianged ring or collar D f1tting around said neck. This nozzle C is preferably of the peculiar shape as shown kin the drawings; it is formed with an enlarged base c as usual, but instead of lthe customary tapered form it has a contracted central tubular portion c', and a still further contracted tubular portion c2 at the end. The purpose of this peculiar construction will be hereinafter pointed out and thoughit is not essential to the operation 4of the device it is preferred.

E is a circular plate having a central perforation c through which the nozzle C passes, two smaller perforations c', c through which suitable guide rods pass and an annular groove e2 surrounding the central perforation e on its upper side for the reception of the coiled end of a spiral spring.

F, F, are two guide rods provided with screw threadedends floeveled notched ends or heads f and notches f2.

G is a centrally perforated yoke adapted to it over the nozzle C and provided with perforated projections or lugs g, g, through the perforations of which the rodsF pass. The notches of the heads f of the rods F fit over the edge of the collar D and the perforated lugs g, g of the yoke G engage in the notches f2 and thereby firmly secure said rods to the collar D and brace them against endwise'movement so that they will always assume the properposition. The heads f are beveled on their ends to prevent interfering with the neck B. f

H is a spiral spring surrounding the nozzle C and confined thereon between the yoke G and the circular plate E, said plate E being confined by means of the screw nuts f3 which l engage with the screw threaded ends of the guide rods. The plate E has formed on its under surface an internally screw threaded annular collar c3 as shown in Fig. VI.

K is atubular sleeve having screw threaded portions k, k at its ends, the end 7c being adapted to engage in the screw threaded col- IOO lar e3 of the plate E and confine between it and the base of said plate a perforated flexi lble washer L, which fits snugly around the central cylindrical portion c of the nozzle C and prevents the entrance of any foreign substance into the sleeve K.

M is a cap-piece internally screw-threaded `and adapted to engage the outer end 7c of said sleeve K.

N is a slit or perforated fiexible disk confined between said sleeve K and the cap-piece M, the perforation of said disk being preferably in theform of a short slit.

In Fig. III'pl I have shown a modified coustruction of the outer end of the sleeve K. Instead of the screw-threaded portion k2 and the screw-cap M carrying the disk N, in this modification ofthe sleeve K is formed with an outwardly and upwardly curved flange 7e3 and arubber or other suitable elastic cap or thimble N is provided having a contracted neck n for engaging with the collar or flange 7c3. This thimble N is provided with a slit n2 as in the flexible disk N. C represents the nozzle as in-the other views, the operation of the parts being substantially the same. \Vl1en the parts are in their closed or normal position as shown in Figs-I, III, IV and IX, the end of the nozzle is just inside of the fiexible disk N, the slit in said disk being closed, by its elasticity. When it is desired to use the oil, the nozzle is thrust through the slit in the flexible disk N, into the lubricator cup O, against the action of the spring H, by pressing the edge of the cap M (carried by the sleeve K and plate E) against the edge of the lubricator cup, (as shown in Fig. II) which allows the oil to iiow out into the cup, the nozzle and guide rods sliding through their respective perforations in the plate E.

After the required amount ofq oil has passed,

the pressure is removed and the spiral spring forces the parts back to their normal position,

the perforated flexible disk N fitting snugly around the end of the nozzle and removing all dirt which may have adhered thereto when it Was inserted in the cil cup or other journal lubricator. The flexible Washers or disks L and N rest respectively upon the tubular portions c and cfaof the nozzle around which they fit snugly and prevent the entry of any dirtV into the sleeve K and consequently into the nozzle tube C.

When my improved oil can is to be used without the aid of the oil cup, the plate E carrying the sleeve K and cap-piece M, is pushed inwardly against the action of the spring H, by means of the thumb and finger,

until the end of the nozzle protrudes through the slit in the flexible disk Q and the oil Y iiows out as usual.

formed integral therewith.

ed cap fitting on the screw threaded top of .the oil cup and securing between it and the oil cup a perforated fiexible disk Q; which disk is of the same form and structure as the disk N. The object of the perforated or slit flexible disk in this instance is the same, that is to exclude the entrance of foreign substances. But my preferred form of lubricator cup is shown in Figs. VIII"L and VIIlb. In this form the cup O is provided with an outwardly and downwardly curved fiange o at top, over which an elastic cap or thimble Q is adapted to fit, said thimble being provided with a contracted retaining neck q for engaging with the flange o and securely holding the thimble in place. It is obvious that the elasticity of the thimble will hold it in place. This thimble Q is made much thicker at q where it is perforated for the reception of an oil can nozzle. If it is desired the thimble Q can be made very satisfactorily as shown in Fig. VIII", with a cup or annular flange q2 This form is advantageous for catching any oil drips from the nozzle and thereby preventing the waste of oil, and it also serves to strengthen the thimble.

When the lubricant is to be inserted in an oil cup of my improved construction the nozzle C of an oil can is thrust through the slit as shown in Fig. II, the flexibility of the disk allowing the perforation to expand for this purpose, and the elasticity of the disk automatically closing the perforation when the nozzle is withdrawn.

It is obvious that my invention could be employed in combination with various forms and constructions of lubricators, which are not herein shown, without departing from the spirit thereof.

Having thus described my invention the following is what I claim as new therein and desire to secure by Letters Patent:-

l.
