ROLLER-BEARING GUIDE.

Patented July 30, 1907.

Application filed February 25,1905n'SerialNo. 247,217.

To all whom it may concern:

Be it known that I, CHARLES S. LOCKWOOD, acitizen of the United States, residing at 289 Market street, Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvcments in Roller-Bearing Guides, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The present invention relates to a guide for the group of rolls which are often revolved in contact with one another in a roller bearing, and the inventon furnishes a guide having collars at opposite ends,

and divided into two .parts, with the collars notched to form an overlapping joint. The half-collars may be connected by detachable i'astenings, but I prefer .to notch the lugs in a peculiar manner so as to make "the halves of the guide-frame interchangeable, and

' adapted to interlock.

their proper longitudinal relation to one another when revolving within the casing, so as to prevent either from moving longitudinally and rubbing against the casing While revolving with therollers.

The invention will be understood by reference to the annexed drawing, in which Figure l is apcrspective view 01' one half of the guide having half-lap joint; Fig. 2 is a section o'l a roller bearing, the casing being divided longitudinally at its center line, with the shaft, roller guide, and rolls represented within such bearing. Fig. 3 is an end view of the guide and rolls detached hour the bearing, the halves of the guide in these three views being similar and suited for use with an even number oi rolls. Fig. 4 shows a guide for an odd number of rolls, requiring two dissimilar castings to iorm the complete guide; Fig. 5 is a view of the lower casting and Fig. 6 a view of the upper casting, both in transverse section across the tie-bars. Fig. 7 shows half collars for locking the parts of the guide together. Fig. 8 is a side view of a guide having locking plate applied to the joint; Fig. 9 is a transverse section of the same across the tie-bars, with one of the locking plates in position, and the other removed to show the pin holes; Fig. 10 shows the inner side of the locking the'half guides are matched together. The casinghas'epposite heads, with internal space sufiiciently 1 longer than the rolls, to admit the half-collers to turn loosely between the rolls and such heads.

The ends of the half collars which project beyond the tie-bars ,1; form lugs c which at one side of the half collars are formed with notches d upon the outer side, and at the other side of the half collar are formed with notches d upon the inner side, so that they are interchangeable with one another, and any number of castings of such shape may be made from the same pattern. The lugs are so notched that a pair of such half collars will fit together with the lugs interlocked and any end movement of the half collars upon one another be prevented. Fig. 3 shows the groups of rolls a between the various tie-bars, and as the rolls fit snugly between the shaft A of the roller bearing and its casing B, the rolls hold the tie-bars in a fixed position between the groups, and. thus tend to prevent any separation or displacement of the half collars. A guide in which the two halves are made from the same pattern or casting, as in Figs. 1 to 3, isjadapted to support an even number of rolls in the bearing, but where an odd number of rolls is required to encircle the shaft in a casing of given size, the halves of the guide are not interchangeable as the tie-bars cannot be disposed at equal distances from the dividing line, and the halves of the guide are made of different patterns or castings, with all of the lugs upon one half notched externally and the lugs upon the other half notched internally. This construction is shown in Figs. 4 tot inclusive, with one roll 0 between the bars I) at one side of the guide, and two rolls 0 between the bars b at the opposite side of the guide, and the tie-bars being suitably disposed to admit such a number of the rolls.

Fig. 5 shows one half of the guide with the lugs 0 having notches (2 upon the inner side, and Fig. 6 shows the other half of the guide with the lugs 0 having notches d upon the outer side. The effect of the construction is the same as that of Figs. 1 to 3, as the rolls contact with the various guide bars in such manner as to prevent the displacement of the half collars, and the notched lugs are thus held together and the guide res volves around the shaft as a unit. It is customary in guides having collars at the ends to have them fit approximately to the shaft or the casing of the bearing to hold them concentric with the shaft in their rotation; and Fig. 4 shows the sections fitted to the shaft so that casing.

Any suitable means may be employedtf or locking the half collars together if desired. To effect this, locking plates may be applied to the inner or outer sides of the half collars, with pins upon one engaging holes in the pther. The locking plates may be made in the form of if they move into contact with the same, the rotation of v the shaft will assist in propelling the guide within the supplemental half collars e shown in Fig. 7 applied sidesgoi tl ehalf collar is shown in 'iligs.

Half-collars have been used in different roll cages and connected to furnish pivots for the rolls; but my construction relates to a loose roll-guide, and furnishes a special construction of such guide with. divided col lars at the ends, whereby they may be readily applied to opposite sides of the shaft, in cases where the end of the shait is not accessible to slide an integral collar over the same, and suitable means is also shown for locking the half sections together when desired; the locking plates being held in their working position when upon the inner sides of the half collars by the ends of the rolls themselves, and when upon the outer sides oi'the halfsections by the heads of the casing which retains the rolls.
