JOIIN TENWIOK, OF GRANTHAM; ASSIGNOR TO ROBERT CHARLES RAN- SOME, OF IPSWICH, ENGLAND.

Letters Patent No. 111,401, dated January 31, 1871.

IMPROVEMENT IN LUBRICATORS.

The Schedule referred to in these Letters Patent and making part of thesamer To all to whom it may concern.-

Be it known that I, J om: TENWI K, of Grantham, in the county of Lincoln, molder, a subject of the .Queen ofiGreat Britain, have invented or discoveredarrangement for supplying cranks with, oil. It is' ap-. plicable especially to reaping and lllOWlllgflililClllIlBS, but may be used also in other machinery where cranks are employed.

In the crank-plate, which is made of a circular form, and acts as a fly-wheel, Ifor'm a hollow or cavity, and such hollow or cavityI use as a receptacle for the oil.

The crank-plate or fly-wheel may either be cast in one piece with the hollow or cavity in it, or it may be cast or'manuiactured in parts suitably fitted together. I p

The crank-pin is inserted into a. socket in the crank-plate, and through the socket I make one or more holes for the oil to pass through from the receptacle to the crank-pin. I

In the crank-pin, where. it fits in the socket, I

make a hole to convey the oil to the interior of the pin, which is hollow, and another hole-which conveys the-oil to the plaee'where the connecting-rod works; 5 Into the hollowin the crank-pin I fit a regulatingplng. The regulating-plug is made with a groove in it to communicate withthe'holes in the crank-pin. The regulating-plug fills the hollow in the crank-pin, so that the groove in the plug is the only passagehy which the oil can escape to the exterior of the crankpin to lubricate itand the connecting-rod working thereon, and the 'size of the groove regulates the I secure the regulator-plug to the crank-piujwithiaevashcr and pin or screw, or in other convenient means.

In the rim or outside edge of the crank-plate is. a hole'to suppIy the oil, and, in' order to stop the lastmentioued hole, I use a plug or piece of cork or other suitable material. I

;If desired, a second lubricating cavity may be provided in the crank plate to lubricate the crank-axis in a similar manner, the axis having a passage in it commimicating both with the cavity and with the bearing of the crank-shaft, and being provided with a regnand by the lating-plug, as already described in respect to the crank-pin. I

My invention can be more readily understood by referring to the drawing which accompanies thisspecification, but I wish it to be understood that I donot bind myself to the exact shapes and dimensions shown therein, as these can be altered without departing from my invent-ion.

Figure l is a side-view of the crank-plate and lubricating-cavity with the cover-plate removed; Figure 2 is a vertical section, and Figure 3 a horizontal-section of the same.

f is a collar on the crank-pin forsecnring the connecting-rod; and

g, a pin by which the collar f and plug 0 are held in their places.-

Having. now described and vention, and the means for carrying the same "i'u'to efi'ect, p

I would have it understood that I claim- 1. The combination of the crank-plate,constructed with a lubricating-cavity,and the hollow crank-pin, so arranged that the lubrieating material may pass from said cavity to the journal of the cra'nkpin, substantially as before set forth.

2. The'combination of the said crank-plate,thehollow crank-pin, and the crank-shaft,-so that both the crank-pin journal and vvthe journal of the crank-shaft may be lubricated by lubricating material supplied from the crank-plate, substantially as before set forth.
