To all whom it may concern:

Be it known that I, WILLIAM BELL LOWE, a citizen of the United States, residing at Marietta, in the county of Cobb and State of Georgia, have invented certain new and useful Improvements in Lubricating Devices; and I do 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, lwhich form a part of this specification.

My invention relates to lubricating devices, but more particularly to a force-feed lubricator for journal-boxes7 and my invention has for its object to provide a device of this class which will elfectually lubricate the shaft and journal-box with a minimum amount of oil and with practically no waste of the same.

A further obj ect of my invention is to provide a lubricating device which filters the oil after passing from the j ournal-boX and shaft before again being forced into the journal- A further object of my invention is to provide a continuous lubricating device, as will be hereinafter more fully described.

With these objects in view my invention consists in the novel construction of the forcefeed.

My invention further consists in the novel construction for leading the oil to the journal box and for returning the oil therefrom.-

My invention further consists in the novel construction of the Babbitt-metal lining for the journal-box.

My invention further consists in certain other novel features of construction and in combinations of parts, which will be first fully described and afterward specificallypointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a vertical sectional view taken through a j ournal-box constructed in accordance with my invention. Fig. 2 is an end elevation of the same Fig. 3 is a vertical transverse sectional view taken on line 3 8 of Fig. 1. Fig. 4 is a vertical transverse sectional view taken on line 4 4 of Fig. 1. Fig. 5 is a plan view of the lower section of the journalox, showing babbitt lining and oil lubricator. Fig. 6 is an elevation of one of the rollerdisks. Fig. 7 is a fragmentary sectional view taken on line 7 7 of Fig. 6. Fig. 8 is an elevation of one of the idler-disks.

Like numerals of reference indicate the same parts throughout the several figures, in which* v 1 indicates the journal-box, which is composed of the lower section 2 and an upper section 3, said sections 2 and 3 being provided with flanges 4 and 5, through which flanges bolts 6 pass to fasten the said two sections together, as shown in Fig. 8. Preferably located at the central point of the journal-box is an enlarged casing 7, as shown in Figs. 1 and 3. A chamber 8 is formed in the lower section 2 of the journal-box.

9 Aindicates the stuffing-box, which is composed of the ring 10, formed in two sections 1l and 12, said sections being provided with flanges 13 and 14 and bolted together with bolts 15, said ring l0`being provided with vertical slots 16, through which'bolts 17 are adapted to pass to secure said ring to the flanges 18 at each end of the vjournal-box- The said ring 10 is provided with an annular concavity 19, as shown in Fig. 1, and a port 20, located at the center of the lower section 12 of the ring 10, leads from said annular concavity 19, as shown in Fig. 1.

Suitable packing material 21 is held in position by means of a ring 22, bolted to the said ring 10 by bolts 23, as shown in Fig. 2, said ring 22 being constructed in two sections 23 and 24, said sections being secured together by bolts 25, which are bolted to the saidsections 23 and 24. This construction is duplicated at each end of the stufling-box, as shown in Fig. 1.

26 indicates the Babbitt metal lining, Which is composed of an upper section 27 and a lower section 28, said babbitt extending from the ends ofthe journal-box to the central casing 7 and chamber 8, as clearly shown in Fig. 1.

29 indicates the 'cam force-feed-operating device, which is constructed in two sections 30 and 31, said sections being secured together by any suitable means-as, for instance, by flanges 32, bolted together, Fig. 4.

Referring to Fig. l in connection with this cam, it will be seen that the same is provided with a centrally-located eccentric-rib. Said member 29 being secured around the shaft 33 revolves therewith, as is obvious.

Referring to the chamber 8, (shown in Figs. 1 and 4,) it will be seen that the mem IOO log

IIO

ber 29 extends within said chamber and revolves within the enlarged covering 7.

Located within the chamber 8 is a cylinder 40, within which the piston 41 operates.

42 indicates the piston-rod, which passes through a suitable box 43, and a cross-head 44 passes through said piston-rod near the outer' end thereof. A coil-spring 45 is located between the cap of the stuffing-box 43 and the said cross-head 44. Formed on4 the outer end of the said piston-rod or connected thereto is a fork 46, designed to hold a single roller 47, said roller being located directly under the eccentric-rib 34 and designed to be in contact therewith.

Referring to Fig. 4, it will be seen that two said casting 49 being bolted to said flange 51, l

as shown in Figs. 1 and 4.

Referring particularly to Fig. 5, 52 indicates filter-screens, which are composed of a series of layers of screens of different meshes, said layers being bolted together by bolts 53 and said screens being located, as shown, between the partitions 5() of the casting 49.

Referring again to Fig. 1, it will be seen that the cylinder' 40 is provided with a lug 54, which is threaded into the bottom of the chamber 8, and extending into the said cylinder 40 at the lowest point thereof are ports 55, said ports carrying a valve 56, and said ports are coupled by means of a couplingsleeve 57 to a nipple 57 at the bottom of the feed oil-pipe 58.

Locatedin the cylinder 40, as shown in Figs. 1 and 4, are ports 59, which are provided with valves 60, said ports entering the chamber 8, as clearly shown in Fig. 4.

Entering chamber 8 above the filtering- .Screens 52 are the return oilways 61, said oilways leading from the concavity 19 in the ring 1() of the stuffing-box 9, as clearly shown in Fig. 1.

Referring to the Babbitt-metal lining 27, and in this connection referring to Fig. 5, it will be/seen that the feed-oilways 58 enter thesaid babbitt Alining at 62, and leading from the point 62 transversely are two grooves 63, said grooves gradually tapering, as shown. Intersecting said transverse grooves 63 are two longitudinal grooves 64,

(shown also in dotted lines) in the upper section of the babbitt lining, said grooves 66 leading to the concavity 19 in the ring 10 of the stuffing-box 9 and also leading to the chamber 8 in the center of the journal-box, as shown in Fig..5.

Referring to Fig. 6, which shows one of the roller-disks 67, it will be seen that the same is composed of two sections 68 and 69, secured together by bolts 70. A series of groups of rollers 71 are carried in the disk 67, said rollers being provided with large bores 72 and held in the disk by means of pins 73, as shown in Fig. 7, said rollers extending beyond the face of the disk, as shown.

Referring to Fig. 8, which illustrates one of the idler-disks 74, it will be seen that said disk is composed of two sections 75 and 76, secured together by bolts 77. As shown in Fig. 1 a roller-disk 67 is interposed between two idler-disks 74 on each side of the cam 29, said disks acting as a thrust-bearing and reducing friction to a minimum.

Having thus described the several parts of my invention. its operation is as follows: The cam member 29 being Secured around the shaft 33 revolves therewith, and the roller 47, carried by the piston-rod 42, is held in contact with the eccentric-rib 34 by means of the coilspring 45. As said shaft revolves the eccentric-rib 34 forces the piston down into the cylinder 40, oil having first been poured into the chamber 8. On the upstroke of the piston 41 the intaking-valves 60, Fig. 4, are opened and the oil is drawn from the charnber 8 into the cylinder 40. On the downstroke of the piston said intaking-valves are closed and the outlet or feed valves 56, Fig. 1, are opened and the oil is forced from the cylinder into the feed-oilways 58 and up into the babbitt lining, said oil passing into said lining at 62, Fig. 5. The shaft 33, revolving within the babbitt lining takes up the oil, and the force of the piston distributes the oil within the transverse groove 63, from whence it is forced into the longitudinal groove 64, the rounded corners 65 of the grooves 63 being for the purpose of facilitating the flow of the oil from the grooves 63 into the longitudinal grooves 64. As shown, the oil-grooves taper in depth and width toward the ends thereof, so that a less quantity of oil is required to fill the grooves near the ends than is required where the oil enters the grooves, thereby insuring an even distribution of the oil along the babbitt lining. 4A portion of the oil, however, is forced transversely along the grooves 63 to the point 80, which point connects with the oblique grooves 66 in the upper section of the babbitt lining. Thus the shaft 33 is lubricated the entire length of the journal-box, the longitudinal grooves 64 extendingthe length of the journal-box and terminating-in the concavity 19 in the ring 10 of the stufIing-box 9, the inner ends of said IOO ' is again drawn into the cylinder 40 and forced` above the filtering-screens 53.

oblique grooves in the' upper section of the babbitt lining also terminate in the concavity 19 in the ring 10 of the stufling-box 9 and also in the chamber 8. by the shaft 33 only a suflicient quantity is held thereby to properly lubricate the same, and the continuous influx of the oil into the babbitt lining forces the superfluous oil into the concavity 1 9 in the ring 1() of the stufiingbox 9 and also into the oil-chamber 8. The oil entering the said concavity 19 passes out through the port 2O into the return-oilway- 61, Where it is again 'led into the chamber 8 The oil passing from the babbitt lining directly into the oil-chamber passes down between the cam member 29, a sufficient quantity thereofbeing taken up by the disks to properly lubricate the same, the excess of oil passing into the oil-chamber 8' and into the filteringscreens 53, Where it is deprived of all dust and impurities Which it may have taken up during its passage along the babbitt lining, and after passing through the filtering-screens it intothe feed-oilways 58, again passing up to the shaft 38, Where it is again used for lubricating. Thus it is seen that absolutelynone of the oil is Wasted and only a sufficient quantity of the oil is consumed to properly lubricate the shaft and babbitt.

Having thus described my invention, I do not Wish to be understood as limiting myself to the exact construction herein set forth, as various slight changes may be made therein which Would fall Within the limit and scope of my invention, and I consider myself clearly entitled to all such changes and modifications.
