SELF-.OILING WH ETSTONE.

SPECIFICATION forming` part of Letters Patent N o. 734,137, dated July 21, 1908.

Application filed November 22, 1902. Serial No. 132,458. (No model.) l

To all whom it may con/cern:

Be it known that LFREDERICK REISSMANN, a citizen of the United States, residing at Westpoint, in the county of Orange and State of New York, have invented certain new and useful Improvements in Self-Oiling Whet stones; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it Vappertains to make and use the same. Y Y

My present invention relates to whetstones, and more particularly to that variety thereof wherein an automatic self-loiling attachment is provided; and my invention `consists in certain novel features of combination and construction of parts, whichvwill be hereinafter clearly set forth, and pointed out in the claim.

The prime object of my invention, among others, is to provide a suitable oil holdingand discharging attachment designed to be conveniently disposed within the usual box or casing employed to hold the stone proper whereby the surface of the stone will be properly supplied with a suitable lubricant of any desired variety, and the construction necessary to materialize this idea will be fully illus,-`

trated in the accompanying'drawings, which are made a part of this application, and in which- Figure l shows arperspective view of myV invention complete ready for use. Fig. 2 is av provide a seat for the Whetstone proper, 2, aV suitable lid 3 being also provided to l inclose the upper half of the stone, asis usual with appliances of this kind. The lid-section is designed to carry the oil attachment adapted to coperate with the whetstone, whereby the upper exposed surface thereof is supplied With the requisite amount of oil, as will be hereinafter more particularly set forth. Within the upper portion of the lid 3 thus or otherwise provided I locate the movable plate 4,which is provided with, preferably, two controlling buttons or extensions 5, designed to take loosely `through suitable apertures 6, provided in a'contiguous part of the center of the lid, as more clearly shown in Fig. l. The bed-plate 4 is of proper size to fit loosely within the upper part of the lid 3 and is held normally upward by means of the oil-spring '7 or the equivalent thereof, which extends through suitable apertures 8, provided in the lid. The lower en d of the spring 7 is connected to the plate 4 in any preferred way,

while the upper end thereof is bent to form the eye 9, through which the retaining or anchoring pin 10 is extended, whereby the plate will be held from casually slipping out of place. l

To the lower side of the plate 4 I glue or otherwise secure the cushion 1l, formedof felt, cloth, or other absorbent material suit-. able for the purpose, as said substance is designed to constitute the oil-reservoir, inasmuch as it is to be kept thoroughly saturated with oil, which will at all times be kept free from grit and allV other foreign andinjurious substances.

\ In some instances I prefer toform an aperture 12, preferably in Athrecentral portion of the push-button or extension 5, through which oil maybe readily introduced to the reservoir of absorbent l material l1, inasmuch as the aperture 12 is designed to register with the corresponding aperture formed in the plate 4.

By the arrangement herein described it will be seen that while the oil-absorbent cushion 1l is heldnormally out of engagement with the surface of the stone 12 such cushion may be readily forced downward into contact with the stone by a simple pressure upon one or both of the buttons 5, thus bringing the entire surfaces of the stone and cushioninto gentle contact with each other and insuringthat the oil-saturated cushion will'evenlydistribute over the surface of v the stone a proper IOO will be deposited upon the stone, whereas a great pressure will insure that a greater quantity of oil will be deposited.

It is obvious that when the oil-ducts l2 are not provided the innersurface of the absorbent cushion 11 may be supplied With the proper quantity of lubricant, though it is thought that best results will follow when the oil is introduced in the manner explained through the apertures 12, inasmuch as the oil will be strained, and thereby purified from any gritty substances or the like before it percolates through the material forming the cushion.

Various modifications may be made in carrying out my invention, inasmuch as it is obvious that other forms of springs may be employed for accomplishing the same result, and I therefore do not wish to be confined strictly to the exact showing herein presented, but Wish to comprehend all substitutes and equivalents that may be considered as fairly falling Within the scope and purview of my invention.

My improved self-oiling attachment may be readily applied as an attachment upon oilstones as now constructed by the simple addition of the parts carrying the cushion and the means afforded to actuate the same, as hereinbefore described.

Believing that the advantages and manner of constructing my improved self-oiling ap# pliance for Whetstones or the like will thus be made clearly apparent from the foregoing specification, considered in connection with the accompanying drawings, further description is deemed unnecessary.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described attachment for oilstones or the like comprising the combination with the lid of the casing of a movable plate-section 4 having extensions or buttons 5 protruding through the casing, means to hold said plate normally upward; a cushion of absorbent material carried by the lower surface ot' said plate whereby when saidv plate is pushed downward the surface of the stone will be brought in contact With said cushion and thereby supply the former with the requisite amount of lubricant all combined substantially as specified and for the purpose set forth.

In testimony whereof I ailix my signature in presence of two Witnesses.

FREDERICK REISSMANN.
