Application led September 12, 1921.

To @ZZ whom t may con-cern.'

Be it known that l, FinNs'r Vieron JUNGK, a citizen of the United States of America, residing at 442 Autum Avenue, Brooklyn, in the county of Kings and State of New York, have invented certain new and useful lmprovenients in l/Vashers, of which the following is a specification.

This invention relates to washers or bushings designed to be applied for example, to the shafting of machinery, or to the shackle bolts on motor cars between the shoulder and the nut for taking up play between said parts, without the removal of the nut or other holding member.

The object of my invention is to improve upon washers of this description so that the two parts of the washer may be applied without loosening the bolt or atleast without loosening it more than the thickness of the washer, and at the same time to design a washer so that the two parts will be permanently locked together when once applied.

Further objects of the invention will appear as the description proceeds.

Referring to the drawing in which what I now consider to be the preferred forms of my invention are shown, Fig. l is a plan View of a removable washer constructed according to my invention showing the key to one side,

Fig. 2 is a plan view of the same showing it in the act of being applied to a bolt or shaft, but before the key has been driven home.

Fig. 3 is a corresponding view after the key has been driven and locked into place.

Fig. 4 is a section on line 4 4 of Fig. l.

Fig. 5 is a detail view of a slightly modified form of key.

The main or body portion of my two part washer is shown at l, while the key is shown at 2. The body portion is provided with the usual central circular aperture 3 the walls of which merge into the parallel side walls 4 and 5 of the lateral opening 6 permitting the washer to be inserted over the shaft or bolt 7 as will be readily apparent. At least one of said parallel and preferably each wall is provided with a recess or nitch 8, 8', which extends beyond the periphery of the recess 3 to receive the prongs 9, l0 of key 2 as hereinafter explained.

rlhe key portion has parallel sides 13 and 14 and is preferably curved on outer rim or Serial No. 500,127.

edge to the same diameter as the periphery of body portion l. )The inner portion of the key is recessed to form one or more prongs 9 and l0. lWhile said recess need not be circular? the radius of curvature of the same is less than the radius of the bolt 7 or of aperture 3, or inother words the distance a ig. l) between the inner ends of the prongs 9 and l0 is less than the diameter or cord by so that the prongs engage the bolt 7 as the key is slid radially into place (F 2). rlhe kev is then struck with a hammeripreferably, unltil the prongs are forced outwardly into nitches 8, 8 and the key is flush with the washer (Fig. 3).

lin Fig. 5, a slightly modified form of key 2 is shown wherein the ease with which the key may be driven into place is increased by reducing the thickness of the prongs 9', l0. rilhe body portion need be varied in no particular since it is not necessary that the prongs completely fill the nitches 8, 8 when the key is in place as shown in Fig. 3. All that is necessary is that the prongs or either of them be bent outwardly beyond the parallel edges 13 and 14 to prevent the key from dropping out, as the nut, when tightened will prevent all lateral movement.

Having described my invention what l claim and desire to secure by Letters Patent is:

l. A two part washer comprising an annular body portion having an openingV in one side adapted to receive a bolt or shaft, a wall of said opening having a recess therein, 'and a key member having a recessed inner portion forming a prong on a side thereof adapted to be expanded outwardly into said recess by said bolt or shaft as the key is driven home.

2. A two part washer comprising an annular body portion having an opening' in one side adapted to receive a bolt or shaft, the walls of said opening having opposite recesses therein and a key member having a prong on each side thereof7 the ends of which are of less distance apart than the chord across said bolt or shaft between the points where the prongs engage the same, whereby said prongs are swaged outwardly into said recesses by said bolt or shaft as the key is driven home.

8. As an article of manufacture7 a take up washer or bushing comprising a body portion with the usual central circular opening and out away on one side on parallel lines to form an opening for insertion of the bolt or shaft, said parallel walls having nitches therein, and a flat key having parallel sides for insertion into said opening and a recess at its inner portion forming opposite prongs, the radius of curvature of said recess being less than the radius of said circular opening, whereby said key engages said bolt or shaft as it is forced into place and the op posite prongs are bent outwardly into said nitches.

4. Asl an article of manufacture, atake up washer or bushing comprising a body portion with the usual central circular opening and cut away on one side to form a lateral opening having walls for the insertion of the bolt or shaft, said walls having portions thereof spaced farther apart than the entrance to said lateral opening, and a fiat key having straight sides for insertion into said opening and a recess at its inner which are of less distance apart than the.

chord across said bolt or shaft between ,the

points where the prongs engage the same,

whereby said prongs are expanded 'outwardly into said recesses by said ybolt or shaft as .the key is driven home.

In testimony whereof signature.
