LUBRICATING DEVICE'.

SPECIFICATION forming part of Letters Patent No. 447,015, dated February 24, 1891. Application filed June 16, 1890. Serial No. 355,595. (No model.)

.To @ZZ whom zit may concern:

Be it known that I, GEORGE T. REIsS, of Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

This invention pertains to that class of lubricating devices designed for use on sliding surfaces disposed in horizontal planes of motion. Horizontal sliding surfaces are Well exemplified in the Ways of metal-planing machines. Considerable difficulty is experienced in securing the proper lubrication of such planer-ways, especially if the planer be designed for the heavier classes of work. The ways of planers generally have a V-shaped section, and attempts have been made to provide for lubrication by means of oil-distributing rollers mounted on horizontal journals and engaging the under surface of the sliding Vs, the lower portion of the rollers running in the oil, springs being provided to hold the rollers up to their Work. The rollers have been spool-shaped to fit the Vs, but the distribution of oil by them has been far from satisfactory; but the difficulties are greatly increased when the V-section of ways is abandoned and a dovetailed section of ways employed.

My present improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which Figure l is a side elevation of a bed and sliding platen provided with my improved lubricating devices, a portion being broken away to exhibit one of the oil-reservoirs in vertical section in the plane of line c,- Fig. 2, a vertical longitudinal section through the oil-reservoir thus exposed in Fig. l, this section being in the plane of line d of Fig. 8; Fig. 3, a vertical transverse section through the oil-reservoir exposed in Figs. l and 2, the plane of this section being that of line a; Fig. 4., a vertical transverse section at one side of bed and platen in the plane of line b,this section cutting a reservoir designed forsupplying the angular dovetailed surfaces of the Ways; Fig. 5, a vertical longitudinal section, on an enlarged scale, of a fragment of Fig. 2, showing more clearly the construction of the suspension-screw; Fig. 6, a vertical transverse section through one side of bed and platen, exemplifying the application of the improved system to ways having V-shaped sect-ions;

and Fig. 7, a face view of one of the lubricat-l ing-wheels illustrated in Fig. 6.

In the drawings, omitting for the present all consideration of Figs. 6 and 7, 1 indicates a machine-bed-the bed of a metal-planing machine, for instance; 2, the platen which is to slide thereon; 3, the horizontal bearing-surfaces thereof; 4, the angular side surfaces of the ways, these angular surfaces forming, in conjunction with the horizontal surfaces, the dovetailed Ways of the machine; 5, the upwardly-projecting lips of the bed,` which engage the angular surfaces 4C of the platen and prevent the platen from rising; G, rectangular recesses or reservoirs formed at intervals in the bed, these recesses opening upwardly to surfaces 3, these recesses, however, being partially closed at their tops; 7, the semi-ceilings which form the partial closures of these' recesses, the semi -ccilings being forlned integrally with the bed-casting; S, levers disposed within these recesses and articulately suspended from the semi-ceilings thereof, these levers projecting under the ceilings and having such projecting ends formed With considerable mass or weight; 9, a cylindrical roller horizontally journaled in the forward end of the lever 8, with its axis at right angles to the line of sliding motion of the platen, this roller having its upper periphery proj ecting through the opening in the top of the recess 6 and into contact with the horizontal bearing-surfaces 3 of the platen; lO, recesses or reservoirs formed in the ways of the bed at various points along the same, and preferably intermediate of the recesses @,these recesses 10 having the character of pockets opening upwardly to the ways at their dovetailed edges; 11, journalpins, one at each of the recesses 10, disposed across the recesses at right angles to the line of platen-motion, the axis of the pins being so inclined as to be substantially at right angles to the inclined bearing-surfaces 4; 12, a thin disk journaled freely, one on each of the journal-pins 11, the inner face of this disk impinging against the inclined bearing-surfaces 4 of the platen; 13, a counterbored hole in each of the semi-ceilings 9 of the recesses 6, the

IOO

base of the counterbore having a concave surface; 14, a screw engaging the lever 8 through the hole 14 and serving as a means for suspending the lever and roller, the screw being fast in the lever and loose in the hole in the semi-ceiling and the under surface of the head of the screw being convex; 15, a spiral spring at each journal-pin 11 outside the disk 12 and tending to press the disk inwardly; 16, a stop-collar on the journal-pin 11, inwardly beyond the disk and serving to limit the inward movement of the disk under the influence of the spring; 17, a collar on the outer end of the hub of the disk 12, the outer face of this collar engaging the wall of the recess 10 while the inner face of the collar is engaged by the outer end of the spring; 18, a rim of leather secured to theinner face of Vthe disk 12 at its periphery, this leather being intended to enhance the facility with which the disk will carry the oil, practice showing, however, that the utility of the leather is very questionable and that the leather is not at all essential; 19, Fig. 3, dotted lines indicating those of the recesses G, which are offset to the right; and 20, inward extensions of the recesses 10, the major portion of the recesses 'l0 being disposed in the ways outwardly beyond the inclined bearing-surfaces 4, while the extensions 2O extend inwardly beyond those surfaces.

It is to be understood that the recesses G and 10 are to be supplied with oil, so that the rollers will dip into the oil and in revolving carry the oil upwardly and deliver it to the platen-surfaces with which they make contact. It will be obvious that the levers S, carrying the rollers 9, are free for rocking motion in all directions by reason of the spherical character of the head of the screws which suspend them. Hence the lever can twist sufficiently to allow the roller to make true contact under the platen, and it can turn on the screw as an axis to allow the axis of the roller to be at right angles to the line of platen motion, so that the roller will be rotated without dragging action, and the lever can oscillate vertically', so that the roller projecting above the surfaces 3, when the platen is not present, will come down when the platen reaches the roller and make nice frictional contact with the platen, the contact being maintained by the counterbalancing effect of the heel of the lever.

The recesses G, with their cylindrical rollers, the., will be distributed along the ways of the machine at asV frequent intervals as may be found needed. The recesses might of course be of such width and the rollers of such length as to extend clear across the hori- Zontal bearing-surfaces 3; but such construction might seriously weaken the ways, and I therefore prefer comparatively narrow rollers, as indicated in Fig. 8, the alternate recesses and rollers being offset, as indicated by dotted lines 19, so that the horizontal surfaces will be fairly lubricated.

The action of the disks 12 for lubricating` the inclined surfaces will be obvious from Fig. 4. The spring presses the disk inwardly with yielding pressure against the inclined bearing-surface, and I recom nend that the journal-pins be so inclined as not to be eX- actly at right angles with the bearing-surface 4, the preferable desire being that the face of the disk touch the bearing-surface only at its periphery, so that the disk in carrying the oil up delivers it at the highest part of the disk, and so that the movement of the platen tends to rotate the disk freely instead of dragging somewhat, as might be the case if the inclined bearingsurface of the platen engaged well down upon the disk. The object of the collar 17 is to permit the spring to rotate with the disk without causing the end of the spring to rub against the stationary wall of the recess, the collar revolving with the hub of the disk. The collar 1G limits the inward movement of the disk, the same as if the inner hub of the disk were extended a proper distance toward the inner wall of the recess 20, but having the collar 16 as a sepa rate feature permits of the removal of the parts through a smaller top opening in the recess. By removing the j ournal-pin 11 the collar 1G may be withdrawn, then the disk may be tipped inwardly and withdrawn upwardly through the top opening in the recess.

The feature ofa journal-pin disposed at an angle to the inclined surfaces. which its disk is to lubricate, and also the subdivision of the lubricating-orifices among several independent lubricators acting on different faces to be lubricated, may be applied to -ways having a V-shaped section in a manner which will be clearly understood by reference to Fig. (3, in which 21 indicates the ordinary Vs of a planer; 22, independent recesses formed in the way-surfaces; 23, journal-pins in the recesses, arranged substantially at right angles to the surfaces to which their disks pertain; 2t, the disks engaging the platen-surfaces by their faces; 25, the springs for pressing the disks facially to their work; 26, the collars for the outer ends of the springs; and 27, radial grooves in the faces of the disks to insure the more ready carrying up of the oil, this groove arrangement being, it is thought, far preferable to the leather rim previously referred to.

No claim is herein made to the specific arrangement illustrated in Figs. 3, and G, and in the sectional portion of Fig. 1^.

I claim as my invention- 1. In a lubricator, the combination, substantially as set forth, of a bed provided with inclined way-surfaces and with oil-recesses in those surfaces, a platen engaging such waysurfaces, a journal-pin disposed across each of said recesses and substantially at right angles to such inclined way-surfaces, and a disk upon each of said journal-pins and engaging the platen with its face.

2. In a lubricator, the combination, sub- IIO Vstantially as set forth, of a bed provided With inclined Way-surfaces and with oil-recesses in those surfaces, a platen engaging such inclined way-surfaces, a journal-pin disposed across each of said recesses substantially at.

stantially as set forth, of a bed provided wit-h horizontal and inclined way-surfaces and With recesses in the inclined Way-surfaces and eX- tended into the horizontal surfaces, a journal-pin disposed across each of said recesses and extensions thereof, a collar on each of said journal-pins in the extensions of the recesses, a disk upon each of said journal-pins with its hub contiguous to said collar and with its face engaging the inclined Way-surfaces of the platen, and a spring upon each journal-pin urging the disk toward its collar.
