LUBRICATING DEVICE.
Specification of Letters Patent.
Patented Feb. 22, 1916.
Application filed July 11,1913. Serial No. 778,503.
To all whom it may concern:
Be it known that I, GEORGE W. BOWEN, a citizen of the United States, and a resident of Auburn, in the county of Cayuga and Stateof New York, have invented a certain new and useful Lubricating Device, of which the following is a specification.
This invention. has for its object the production of a lubricating device and particularly to constructions for uniting the cup and stem thereof; and the invention consists in the novel features of constructions hereinafter set forth and claimed.
In describing this invention reference is had to the accompanying drawings in which characters designate corresponding parts in all the views.
Figure 1 is a longitudinal sectional view of this lubricating device. Figs. 2 and 3 are respectively an elevation and a plan of the stem. Figs. 1 and 5 are respectively a longitudinal sectional view and a plan of the partly formed cup.
This lubricating device comprises a cup, a stem secured to the cup and a closure for the cup, the cup and stem having interlocking parts by which the cup and stem are fixedly secured together. The cup is formed with an opening in its bottom and the stem is passed through the opening and provided with a flange located within the cup and lying on the bottom thereof, the cup and the flange being so shaped that the flange is clamped on the bottom so that the cup and stem are secured together without the use of fastening members.
1 is the cup, 2 the stem, and 3 the closure for the cup.
The cup 1 is usually formed up out of sheet metal and is provided with an opening 4: in its bottom 5; and the stem 2 extends through the opening 4; and is provided with a flange 6 located in the cup and secured thereto, the flange 6 overlying the bottom 5 of the cup and the cup having its barrel portion above the flange shaped to overlie the flange bv being compressed inwardly, and to form the upper side 7 of a groove or socket 8 around the opening 4 in which socket the flange 6 fits, the bottom 5 forming the lower side of said groove. The stem is also formed with an axial bore 9 opening into the cup and having a lateral outlet 10.
The entire barrel portion of the cup above the flange 6 is compressed inwardly so that it is of less diameter than the portion adjoining the bottom of the cup, and hence the cup is formed with an integral outwardly extending base 11. Said base 11 is formed angular as hexagonal and the groove 8 and the flange 6 which fits the groove is also formed hexagonal. The hexagonal base 11 provides a wrench hold and the hexagonal flange 6 and groove 8 fixedly secure the cup and the stem together.
The closure 3 is secured to the cup 1 by screw-threads and is in the form of an inverted receptacle which threads into the cup 1, said closure having a plunger 12 movable therein by means of a screw 13 threading through the plunger, which is held from turning movement, the screw extending through the head of the closure and having a handle 14 at its outer end. The screw is held in any suitable manner from endwise movement. Theclosure 3 is also provided with a flange 15 overlapping the upper edge of the cup 1 and the closure is held from unintentional turning by means of a looking device as a ball 16 arranged in a passage through the flange 15 and extending into a notch in the upper edge of the cup 1. The ball is pressed into the notch by means of a spring disk 17 mounted on the head of the closure 3 and held at its center and having its margin extending across the passage in which the ball 16 is located. The closure and the associated parts form no part of this invention.
Preferably, the stem is elongated and machined from a metal block and is threaded to receive a nut, and the cup 1 is struck up from a sheet metal blank drawn from a flat blank into the form of a cup, and the stem passed through the opening in the bottom of the cup and the portion of the cup above the base thereof compressed by dies into a circle of less diameter than :the base, thus clamping the flange of the stem against the bottom of the cup.
The lubricating device here illustrated is designed to connect the leaf spring of a motor vehicle to the shackle or to the frame or to another leaf spring, and is known as a spring bolt.
What I claim is 1. A. lubricating device comprising a substantially cylindrical cup-shaped sheet metal body having a bottom formed with an axial opening, and a base comprising a stem extending through the opening in the bottom and having a head located on the bottom, a
portion of the body being pressed inwardly to overlie the upper face of the head for retaining the base and the body against relative movement, substantially as and for the purpose described.
2. A lubricating device comprising a sub stantially cylindrical cup-shaped sheet metal body having a bottom formed With an aXial opening and a non-circular socket around the opening, and a base comprising a stem extending throughthe opening in the bottom and having a head located in the socket and substantially fitting the same, a portion of the body overlying the upper face of the head for retaining the base and the body against relative movement, substantially as and'ior the purpose specified.
3. A lubricating device comprising a cup having an opening in its bottom, and a groove around the opening, the bottom of the cup forming one of the sides of the groove and the portion of the cup above the groove being of less diameter than the groove, and thereby forming the other .side of the groove and providing the cup With an outwardly extending base, and a stem eX- tending through the opening and having a flange lying on the bottom of the cup and having its margin fitting the groove, substantially as and for the purpose set forth.
In testimony whereof, I have hereunto signed my name in the presence of tWo attesting Witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 30th day of June, 1913.
