MELVIN NEYVTON LOVELL, OF ERIE, PENNSYLVANIA, ASSIGNOR TO THE LOVELL MANUFACTURING COMPANY, LIMITED, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 449,046, dated March 24, 1891.- Application filed December 19, 1890. Serial No. 375,191. (No model.)
To all whom, it may concern.-
Be itknown that I, MELVIN NEWTON Lov- ELL, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Anti-Friction Roller- Bearings; and I do hereby 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.
This invention relates to anti-friction rollerbearings; and it consists in certain improvements in the construction of the same, as will be hereinafter fully set forth, and pointed out in the claim.
The object of the invention is to provide as an article of manufacture and commerce a complete-self-contained roller or ball hearing box which can be made in various sizes, kept in stock, and applied on any common journal-bearing without any material change of construction.
The invention is illustrated in the accompanying drawings as follows: Figure 1 is a longitudinal sectional view of my improved anti-friction roller-bearing with the contained shaft in'elevation. Fig. 2 is an end view of the same. Fig. 3 is an end View of the same with one of the end pieces D removed. Figs. 4 and 5. are respectively like Figs. 2 and 3, with a modification in the construction shown therein. Fig. 6 is a side elevation view of a common truck or wheelbarrow journal with my device applied thereto.
The construction of myimproved anti-friction bearing is as follows: A marks the shaft in all the figures. A cylindrical case B is formed of common steel or iron tubing of such size as is desired. The inner walls of the case or cylinder B are carefully bored or reamed, soas to present a smooth even bearing-surface' At each end of the case B, on the inside, there is bored or turned out a ledge 01' seat I), in which is seated a ring or washer D, which is of less thickness than the depth of the seat, and the projecting end of the cylinder is rolled or upset over the rings, as at b, to hold the rings in place. In Fig. 1 at the left end of the cylinder the thin end is shown as it appears before it is turned down upon the ring D, and at the right end of the cylinder the thin end is shown turned down over the ring.
In making these devices the ringD will be secured in one end of the cylinder. The rollers C will then be put in anda plug be put in the place for the shaft. The other ring D will then be put in place and the end of the cylinder turned down over it, when the device will be complete, the plug being properly retained in place until it is desired to put the bearing in place on a shaft, when the plug will be pushed out by the introduced shaft. The purpose of the rings D is to prevent the rollers C from moving longitudinally, and also to hold the case B in cylindrical form and prevent it springing under pressure. If it is desired to hold the bearing-cylinder against turning, the rings D may be made with projections 61, which fit in notches d in the ends of the cylinder, as shown in Figs. 4 and 5 but ordinarily this will not be rerequired, and the bearing-case can be applied as seen in Fig. 6. In fact, the bearing-case need not necessarily be held against turning, as it is not very likely to turn in its bearings, and if it should it would do no harm.
One of the desirable features of my device is the uniform exterior of the bearing-case, which permits it to be held in an ordinary journal-box, and it can from time to time be loosened in its holdings and turned so as to change the point of greatest wear and prevent the cylinder wearing out of round inside.
In Fig. 6, E is the frame-piece of the truck or barrow or any like object. E is a halfround notch cut to receive the cylinder, and F is the clip for holding the bearing-cylinder in place. I deem .it unnecessary for me to 9c further illustrate the manner of applying my bearing-cylinder to various journals, as its application will be obvious to any one familiar with machinery.
I am aware that heretofore anti-friction 5 roller-bearings have been made with an outer cylindrical case, as in sheaves, roller-skates, &c., and I do not, therefore, desire to be understood as broadly claiming this feature of my construction; and I am aware that it has I00 been common to retain the rollers in their case by loose washers seated in rabbets in the ends of the ease and kept in place by exterior adjacent parts of the device to which the bearings are applied, and I therefore do not intend to be understood as broadly claiming this feature of my construction.
The chief object of my construction is to provide a roller-bearing which can be handled conveniently as an article of commerce and applied to many common devices; and to this end it is necessary that the roller-case when completed shall consist of not only the shell or barrel, but also of the heads or washers, which parts shall be firmly secured together, so as to constitute an entirety, and be as much so practically as if they were formed of one piece. \Vheu the case is thus formed and the rollers are in place, with a simple plug of wood or a small cylinder of tin or pasteboard inserted in the shaft-opening to hold the rollers in place, the device is ready to be boxed in quantities, transported, kept in stock in hardware-stores, and applied to almost any machine by setting it in an ordinary journal-box or holding; it by a common clip,
as shown in Fig. 6. Such a thing as a commercial roller-bearing has not heretofore been made, so far as I am aware, and the supplyin g of such an article of trade will be of great convenience to builders of machinery.
-What I claim as new is As an article of manufacture, an anti-frietion roller-bearing adapted to be transported and handled as an article of commerce and applied to the journals of various machines, consisting of a cylindrical case or barrel B, having at its ends internal ledges or rabbets 1), rings or Washers D, seated in said rabbets and held firmly in place by the upset ends of the cylinder overlapping the same, as at l), r
and anti-frietion rollers O, contained within said case between the said rings.
In testimony whereof I affix my signature in presence of two witnesses.
MELVIN NEWTON LOVELL.
