HENRY M. LYNCH AND LEWIS EflLLIOTT, 0F WOON'SOCKET, RHODE ISLAND, `AS- SIGNORS, BY MESNE ASSIGNMENTS, TO THE SAID LEWIS` E. ELLIOTT.

WASHER.

Application led October 15, 192'1. Serial No. 507,974. f

To all whom z't-m'ay concer/11,.'

ABe it known that we, HENRY M. LYNCH and LEwls E. ELLIOTT, citizens of the United States, residing at Woonsocket, in the county of Providence 1 and State of Rhode Island, have invented certain new and useful Improvements in l/Vashers,fof which the following is a specification.

This invention relates to an improved Washer, and has among its objects to provide a device of this character which is built up or formed ofy separate parts secured V'together' in such a manner as to provide a unitary reinforcedA washer structure wherein the usual soft compressible material forming the main body portion of the washer is so supported as to constantly retainits proper forln and be protected against wear.

Another object of the invention is to pro- Avide a deviceof this character wherein mey tallic plates positioned upon opposite sides of the filler material are each provided with integral prongs, preferably struck out therefrom7 and adapted to be embedded in the filler material, by means of pressure, to hold the plates against separation from the filler and against rotation relative thereto.

Another object of the'invention is to yprovide a device of this character wherein the prongs are so formed as to insure suitable penetration of the ller when pressed into the filler material and a proper bending of the same within the material to effectively'4 retain the parts in proper position and hold them against separation. Y

Other objects andadvantages of the invention relate to certain novel details of construction and methods of forming the same l as will be more fully set forth in the detailed description to follow.

Referring to the drawings: I

Fig. l is a plan view of the washer;

Fig. 2 is a transverse sectional view of the SH.II1B.1

Fig. 3 is a perspective View of one of the metallic plates.; and, l f

Fig. 4 is a detail sectional view showing the washer in the position which it may assume in practice.. l In the embodiment of the invention illustrated herewith'l designates the filler portion of .theewasher which may be of felt,

cork, fibre, or other suitable material such as is adapted to absorb lubricants or prevent the flow of lubricants or other liquids to portions of mechanism from which it is desired that they be excluded.

2 and 3 designate metal reinforcing plates which are preferably hardened sufficiently to enable them to maintain their form when exposed to a certain degree of strain, and thus prevent the ystructure from becoming distorted byv reason of 'excessive strain unequally applied to portions of its surface.

The plates 2 and 3 are similarly constructed, each being provided with a pluralityfof prongs 4 which are preferably struck out from the body portion of the plate by means ofdies, and appeaigbefore the parts are assembled, substantially as shown in Fig. 3 of the drawings.

The tip of each prong is preferably bent slightly as indicated at 5 to insure the entry of the same into the filler .material and that the prong will be bent in the desired direction, that is in the direction of the opening in the plate from which it has been struck out, as thepoint passes through the filler material and contacts with the inner surface of the plate upon the opposite side thereof'. The 'filler material 1 is in the form of an annulus being provided with a central opening 6 for the reception of a shaft, and the diameter of the filler 1 is somewhat greater than that of the plates 2 and 3 so that the periphery thereof may extend beyond the peripheries ofthe plates 2 and 3 when the parts are in assembled position and contact with the interior surface of a cylindrical member within which it may be placed. Each of the plates 2 and 3 is also provided with a central opening 7 of somewhat larger diameter than the opening 6 formed in the filler whereby when the metal plates are positioned upon opposite sides of the liller member the surface area of\the\ illermember exceeds that of either of the plates and extends beyond the same both outwardly and inwardly along every lineof cross section taken through the filler and plates and passingthrough the center of the annulus. I

In assembling the parts to' form the washer as shown in Figs, 1 and 2y of the drawings,

to opp are secured-to thehller with sufficient iirm# ness to normally hold the parts together and form in etlect a unitary structure. v

llt will be understood that the sott compressible material of which the ller is formed issomewhat compacted together by the pressure exerted in securing the plates' osite sides thereof, and this compactness is retained to a considerable extent be understood that other equivalent meansA after the `pressure is removed, thus provid' maybe employed tor this purpose which will tall within the scope oit our invention as dehned by the appended claim, such, torr example, as the securing ot the plates together through the iiller material in any suitable or desired manner so'as to positivel attach the metallic plates'to eachother and old the several parts against separation. "As illustrating one application. ot the' invention there has been shown in l? ig. l oil that the periphe the drawings, a portion ot a cylindrical casing l0 within which is rotatably mounted a shaft ll supported by a roller bearing 12,' the rollers i3 thereotbeing confined in the usual cage it, and a nut l5 being employed tor holding the bearing against removal troni theshait. The shaitt lll rotates in a sleeve le, and a washer 1.7 tormedas above described is interposed between the sleeve l@ and the roller bearing cage it. lt will be seen from the structure as shown in vFig., l ot the ller member l contacts with the inner surtace oil the cylindrical casing to prevent excessive tlow oit lubricant trom the interior of the casing, and the plates Zand 3 upon opposite sides vot the tiller material bear against the relatively moving parts such as the sleeve ll and the cage. la to prevent wearupon the tillen For purposes ot illustration,v there has intenser been shown one practical application ot our improved washer, namely, the use ot the same when positioned between relatively rotatable surfaces. llt is to be understood however9 that the structure' shown and described has many other useful applications, and may 'be advantageously used between relatively non-rotatable members as well as relatively rotatable members, the arrangement ot the parts and characteristics of the structure being such as to adapt it for use generally wherever washers ot yielding material may be employed. i

lllhile we have shown and described in considerable detail one embodiment which our invention may assume in practice in' order to make clear to those slrilled in the art means tor practically utilizing the same, it is to be understood that we do lnot desire or intend to be limited to the precise construction shown and described but that -may employ such equivalent arrangement oi parts as may properly-be included within the scope of the appended claim when broadly construed in the light ot our in' vention.

Having thus described our invention, v

we claim is: Y r i ln at washer ot the character described9 a layer bi yielding material, annular forcing plates psitioneol upon opposite sides ot said yielding material and each provided with integral prongs struclr out 'trom said plates, the prongs ot the separate plates being arranged in non-registering relation and the prongs ot each plate being adapted c to engage the opposite plate upon the parts being pressed together whereby thev prongs are bent back towards their respective plates to engage the material, said plates being thereby retained in position relative to'each other solely through the engagement ot said A.prongs with said yielding material while movement ot the plates towards and troni each other is permitted.
