LUBRICATING DEVICE.

Specification of Letters Patent.

Patented May 12, 1914.

Application filed February 25, 1913. Serial No. 750,624.

To (ZZZ whom it may concern:

Be it known that I, l VILLIAM H. JACK- sox, a citizen of the United States, residing at Jackson, in the county of Jackson, State of Michigan, have invented certain new and useful Improvements in Lubricating Devices; 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 appertains to make and use the same.

This invention relates to oiling devices fer carpenters plane.

The object of the invention resides in the provision of an oiling device which may be readily associated with a carpenters plane in position to constitute the forward gripping handle of the plane.

A further object of the invention resides in the provision of an oiling device of the character named which will normally prevent the passage of oil therefrom to the lower face of the plane and which may be conveniently and readily operated to deliver the desired quantity of oil to the lower face of the plane.

lVith the above and other objects in view the. invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters of refer ence denote corresponding parts in the several views, and in which- Figure 1 is a side elevation of a carpenter's plane partly in section and showing the oiling device associated therewith; Fig. 2, is a plan view of a fragment of what is shown in Fig. 1; Fig. 3, is a section on the line 33 of Fig. 2 on an enlarged scale, and Fig. 4, is a section on the line 4-4 of Fig. 2 on an enlarged scale.

Referring to the drawings 10 indicates a carpenters plane which includes the usual bottom plate 11. This plate 11 is provided at its forward end with a central threaded opening 12.

The oilin device is shown as comprising a head 13 the lower end of which is reduced and threaded as at 14. The upper end of the head 13 is provided with a concentric annular flange 15, the outer wall of which is threaded as at 16. Disposed centrally in the head 13 is a vertical passage 17 which is ntersected by a transverse recess 18 openlng through the side of the head 13. Threaded in the recess 18 is a valve 19 which is adapted to open and close the passage 17 as will be obvious. Threaded on the flange 15 is a casing 20 which is of a suitable shape to constitute the forward gripping handle of the plane when the device is applied as will hereinafter appear. The upper end of the casing 20 is dished as at 21 and provided with an opening 22 for a. purpose that will presently appear. A ca 23 is threaded on the outer end of the flange 15 and is provided with a plurality of diagonal ports 24 and a central passage 25 disposed in alinement with the passage 17. Formed integral with the cap 23 and disposed on the upper side thereof is a casing 26, the upper end of which is provided with an opening 27 disposed in alinement with the passages 25 and 17. Slidable in the passage 25 and opening 27 is a stem 28 which has fixed on the inner end thereof a plunger 29 disposed between the head 13 and the cap 23. Threaded on the stem 28 and disposed in the casing 20 is an adjusting nut 30 and encircling said stem is a spring 31 one end of which bears against the upper end of the casing 26, while the other end thereof bears against the nut 30. Threaded on the outer end of the stem 28 and slidable in the opening 22 of the casing 20 is a push button 32. The wall of the casing 20 is provided with a threaded opening 33 in which is engaged a stopper 34 whereby the casing may be readily supplied with a quantity of oil.

I applying the device to a plane the reduced threaded end 14 of the head 1.3 is engaged in the opening 12 and the casing 20 supplied with oil. The valve 19 is then adjusted to allow the proper quantity of oil to flow through the passage 17 As the oil is needed in the operation of the plane it is only necessary to slightly depress the thereof and be fed gradually to the passagel? so that the delivery of oil from said passage 17 will be slow and even.

What I claim is z- An oiling device for planes comprising a head having a reduced threaded lower end adapted for engagement in a threaded opening in a plane bottom, said head being provided With a central longitudinal passage and a transverse recess intersecting said passage, a valve threaded in the recess and controlling the passage, a concentric flange on the upper end of the head, a cap threaded on the outer end of said flange and provided With ports, a casing threaded on said flange and having an opening therein, a stem slidably mounted in said cap, a plunger head fixed on the inner end of said stem and disposed between the head and cap, spring means constantly tending to hold the stem and plunger head in a given position, and a push button threaded on the outer end of the stem and slidable in the opening in the casing whereby the stem and plunger head may be moved against the tension of said spring means.

In testimony whereof, I affix my signature, in the presence of two Witnesses.
