STEPHEN USTICmmm-Pg' 71m MDT. IN LUBRICATING LOOSE PULLE YS :NVENTbR MW @1% VViTNESSES /XW/ H nlA l W im' `S'IEPPIEINT USTIGK, OF PHILADELPHIA, PENNSYLVANIA.
Letters Patent No. 111,590, dated February 7, `1871 antedated January 2t, 1871.,
I MPROVEMENT IN LUBRICATORS FOR LOOSE PULLEYS.
The Schedule .referred to in these Letters Pat-ent and mking part of the same.
I, STEPHEN Us'rren, of the city of Philadelphiaaud State of Pennsylvania, h. ve invented certain Improvements in Lubricating Loose Pulleys, of which the l` following is a specification.
AMy invention consists of an oil-chamber formed, by
means of a `tube closed at its ends, to the periphery of the shaftV which carries the pulley, and to which the tube is permanently attached or securely fastened, the said tube having an opening for the admission of oil for the iilling of the same, and is closed by means' of a plug, and one or more openings for the passage of the oil to the eye of the pulley,'as hereinafter dev scribed.
To enableothers skilled in the art to which my im-` provexnent appertains to make and use my invention, I will now give a detailed description thereof.
In the accompanying drawing, which makes a part of this specitication- Figure 1l is a side view of one end of 'a shaft, A, with the improvement attached, partly in section.
Figure 2 is a cross-section of the vsame at the line :t a: of iig. l.
Figure 3 is a longitudinal section of the tube 1C, showing a modification inthe plan of constructing it, and a modification in the form of the opening e.
Like letters in all the figures indicate the same parts.
vA is one end of a shaft.-v p
B is an annular chamber for holding the oil for lubricating the eye of the pulley,the chamber being formed by means ofthe tube C, supported at its ends by the collars aI a, which I usually shrink on the shaft. The tube is of s'uicient length to receive the hubs of both the tight and' loose pulleys. It is supported in the middle by the collar al, which has openings b communicating with the chambers B B.
The tube C may be advantageously fastened by shrinking it upon the collar, thus dispensing withthe expense of boring it.
.D is a screw-plug, which closes an opening for the supply of oil to the oil-chamber, the opening being situated outside of' the hub of the loose pulley so as not to interfere'with pouring oil into the chamber.
If desired, the chamber may extend only to the collar et. The oil oozes through packing ot" fibrous or porous material, d, in one or more openings e. vThese openings are enlarged in the middle, as represented, so that, when the packing is pushed into place and springs outward to the surface of the holes, it will incline to the middle thereof, between the inner and outer peripheries of the tube G, and thus be held securely in place. v
Instead of the openingsc being circular, they may be of slot form, as shown in fig. 3; or there may be small perforations instead, for the passage of the oil. p
.Instead of forming the tube C in the manner described, it may be cast of brass or other metal, with the chamber B cored out, and then slipped onto the i 'the shaft A, formed by means of the permanent tube C, and the shaft A, which forms a bearing for the eye of the loose pulley, and is constructed substantially iu the manner and'for the purpose above set forth.
2. The. chamber or chambers B, formed by the pcriphery of the shaft A, and the interior periphery of the tube O, whose outer periphery forms the bearing for the eye ofthe loose pulley, the saidetubc being closed at its ends, where it is made fast to the shaft A, and having an opening for filling the chamber with oil, and' egress-openings to the eye of the pulley, substantially as described. v
In testimony thatthe above is my invention I have hereunto set my hand and aiiixed my seal this 5th day of May, 1869.
