TIMOTHY GINGRAS, OF BUFFALO, NEW YORK.

WASHER.

SPECIFICATION forming part of Letters Patent No. 501,207, dated July 11, 1893.

Application filed December 14, 1891. Serial No. 414,969- (No model.)

which it appertains to make and use the same.

This invention has general reference to improvements in axle washers; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as

hereinafter first fully set forth and described and then pointed out in the claim.

In the drawings already mentioned, which serve to illustrate this invention more fully, Figure 1 is a plan of an axle washer blank previous to its being formed into a helix. Fig. 2 is an elevation of a washer coilready for the market. Fig. 3 is an end elevation of the same. 7

Like parts are designated by corresponding letters of reference in all the figures.

The object of this invention is the production of a helical coil to be used as axle Washers by cutting therefrom a portion sufficiently long to embrace the axle upon which the washer is to be used, such Washer-coils consistin g of a series of axle-washers having slits or cuts in their external peripheryand adapted to be cut into individual washers. To attain, this object, I construct this coil from strips of leather, raw-hide, vulcanized fiber, paper or paper pulp properly treated to render the same flexible, or any other suitable substance or material, A, of proper width and thickness, and produce along one side thereof a series of incisions or excisions B, thus forming, as it were, a series of sections D, connected together by the roots E. These strips I then form into a helical coil 0, Fig. 2, of

proper length so as to contain about twelve,

(more or less,) convolutions, winding them upon a suitable mandrel so as to permanently set the convolution s. This has the effect, when incisions are made only of widening them and thereby produce lubricant retaining spaces so that a washer, though made of comparatively rigid material or soft metal such as lead, and the like, will form a perfect and suitable washer for carriage and other vehicle axles. By producing these incisions along the outer side of the washer blank I attain other important results, viz: I can produce the widest strips and form them into a coil to be used as washers, such wide washers not havingbeen made by forming, as described but having to be made from hides of leather by cutting, it

being readily seen that my strips are'very narrow at the roots of the incisions and therefore readily formed into a coil. Washers of any diameter may be made from these strips by cutting from the coil more or less than one convolution which will readily adapt themselves to the axle upon which they are to be used.

' Vulcanized fiber, as heretofore mentioned, is an article of manufacture well known to the trade so that I do not believe it necessary to describe its manufacture.

Having thus fully set forth my invention, I claim as new and desire to secure to me by Letters Patent of the United States-- As an improved article of manufacture, a series of axle-washers, formed into a helix having a number of convolutions and having slits or cuts in their external peripheries and adapted to be cut into individual washers, as and for the purpose described.

In testimony that l claim the foregoing as my invention I have hereto set my hand in the presence of two subscribing witnesses.
