OILING DEVICE FOR DRILL sHARrENER's,
Application filed September 21, 1923; Serial 1%. 8 54,0136,
To all whom it may @oncem Be it known that I, ARTHUR vE. PETERs, a citizen of the United States, and a resident of Littleton, county of Arapahoe, and State of Colorado, have invented a certainOiling Device for Drill Sharpeners, of which the following is a specification, accompanied by drawings.
This invention relatesto drill steel sharpi-i eners of the mechanical type, having a vertically movable fluid actuated die carrying cross head, controlled by a piston.
The cross head rods of drill Sharpeners have heretofore been lubricated by oil applied periodically by the operator by means of an oil can. This oiling is often neglected or insufficient and results in excessive wear on the rod. The object of this invention is to provide automatic means by which lubricati on of the rod is secured with very little attention from the operator. The oiling is operative only while the machine is in use so that it unnecessary to cut off the oil supply when the machine is stopped. In its re- 5 ferred form, the oiling means is formed integrally with parts which are ordinarily used for other purposes and perform other functions. This makes the machine but very little more complicated or expensive to construct than heretofore.
Other objects and advantages of the invention will be in part obvious and in part pointed out hereinafter.
The invention accordingly consists of an oiling device having the features of construction, combinations of elements and arrangement of parts exemplified in the following detailed description and the scope of the application of which will be indicated in the appended claims.
The drawing is an elevation partly in section of a drill sharpener including an oil feeding device constructed in accordance with the practice of the invention, only so much of the sharpener being shown as Will serve to illustrate the invention.
Referring to the drawings, there is shown a drill sharpener comprising a base A, a
main cylinder frame B secured thereto in a suitable manner, a cross head rod G, vertically movable in the main cylinderframe and actuated by apiston (not shown) within the main cylinder frame to raise and lower the cross head D, and provided with suitable clamping and swaging dies, and a dolly cylinder E supported on bracket F integral with the cylinde frame B. Motive fiui, such as compressed air is supplied tethe inachine through an apertur G in the base, and may be controlled by suitable valves to operate the cross head rod C, theeXhaiist alt being educted through a sjui'table'pip'e The valve action, not being a feature o'f'the invention, is not shown, it being understood that this may behoused within suitatie chest J. i 1
One Of the several ar-ts at which lubrication is particularly desirable, is at the bear;- ing of the cross head rod G in the guide Oil or suitable lubricant is supplied; t6 this hearing at an annular roove L, in the s ide of the guide by a pump, which is attuate'd simultaneously with theeross head. This pump is preferably formed integral with the cross head guide rod 0, which forms the pump plunger and which reciprocates in a cylinder Q in the cross, head, as the latter moves up and down under the control of the operator. The guide rod 0 'is'holiow as at P to permit the flow of oil thereth'roiigh, and is fastened in a suitable manner byalo'oking key 0 in the main 'ylinder frame B, to form a well R underneath, communicating with the annular groove Lthrough a passage S. The cylinder Q eXtends through the cross head D and the open upper end is adapted to be closed by a hollow plug, oroiler T, held in place by suitable means, such as a set screw U. The exterior of thefplu T tapered so as to leave a small space for air to pass in and out of the cylinder through relief hole V bored in the side and near the upper end of the cylinder. The oiler T is provided with a plurality of perforations in its bottom through which oil may pass into the cylinder, and is hollow and filled wit-h a suitable substance, such as oiler wool 'for the purpose of straining the oil passed through the plug. At the top of the oiler T there is provided an aperture through V which oil may be poured into the cylinder the bottom of the plug.
The relief hole is of a size to permit the escape of the greater part of the air from that portion of the cylinder above the surface of the oil, since a few ounces of pressure is all that is required to provide the proper oiling. The amount of oil supplied may be regulated by properly proportioning the size of the hole V. In order to fill the Well R, the filling plug N is removed and oil is poured through the hollow plug T being strained by the oiler wool within the plug T, and then finding its way into the cylinder Q through the perforations in The relief hole V is preferably located in the cylinder above the bottom of the plug T, so that the oil. poured into the plug will. not find its way through the relief hole.
Drill sharpeners of the type above described may readily be reconstructed and provided with this oiling device, it being a matter of" little difiiculty to provide the guide rod O with a longitudinal bore P, to provide the passage S in'the piston guide K, and change the cross head D to conform generally with the construction above described.
As many changes could be made in the above construction and as many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings be in terpreted as illustrative and not in a limiting sense.
It is also to be understood that the language used in the following claims is intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the inven tion, which as a matter of language migl'it be said to fall therebetween.
I-claim:
1. In a drill sharpener, the combination of an oil punp comprisi-g stationary plunger having a well at the lower end, reciprocatory,cylinder, a filling plug in on end of said cylinder having perforations i1 its lower wall and a relief hole disposed in said cylinder above the level of the lower end of said plug.
2, In a drill sharpener, the combination of a guide, a cross head rod in said guide, a cross head on said rod, and means for supplying oil to said rod and guide, including a hollow stationary plunger forming a guide for said cross head and having a well at the lower end communicating with said rod guide, and a cylinder for said plunger in said cross head and having a compression space above said plunger and a relief hole to relieve the greater part of the pressure in said cylinder caused by reciprocation thereof.
3. In a dr ll sharpener, the combination of a guide having an annular groove, a cross head rod reciprocatory in said guide, a cross head'on said rod and means for supplying oil to said annular groove, comprising a stationary plunger forming a guide rod for said cross head and having a well at the lower end communicating with said annular groove, a cylinder integral with said cross head provided with a relief hole near its top and an oiling plug extending down into said cylinder, said oiling plug being hollow and perforated at the bottom below said relief hole and filled with a straining material. I
4. In a drill sharpener, an oil pump comprising a stationary hollow plunger having a well at the lower end, a reciprocatory cylinder, and means to relieve a greater part of the pressure in said cylinder while the pump is in operation.
in testimony whereof I have signed this specification.
