Letters-Patent No. 96,720, dated November 9, .1869.,
IMPRV'ED ANTI-FRICTION BOX.
The Schedule referred to in these LetteraPatent and making part of the same. l
I, JOSEPH L.V PARRY, of Philadelphia, county of Philadelphia, State of Pennsylvania, -have invented an Improved Anti-Friction Box, of which the following is a specification.
Nature and Object .of the Intent-ion.
Description of theAccmnpafng/ing Drawing.
Figure 1 is a .sectional view of my improved anti.-
friction box;
Figure 2, a front view, with portions removed; and
Figure 3 illustrates'a modification of ,my invention.
General Description. f
A represents part of the axle of a wagon, and B, part of the hub of a wheel, or Amay be supposed to represent any revolving shaft, that of a propeller for instance, and B, part of a box or bearing.
In -the following description-of the invention, however, A will be referred to as representing part of an axle, and the hollow cylinder B as partof the hub of a wheel, revolving on the axle.
Two collars or disks, a and a', are formed on the axle, and against the peripherie's of these disks bear the portions d and d of a series of rollers, D, six being shown in the present instance.
These rollers arearranged around the axle atequal distances apart from each other and from the centre of the axle, asshown in iig. .2, and the enlarged portions e of the. rollers are arranged to bear against the inside ofthe hollow cylinder B, which is made in two parts, the cylinder proper` and a .fo ll'ower, f, arranged for insertion into and withdrawal from the cylinder, in which is formed a shoulder, h, the enlarged portions of the rollers ttiug freely between the said shoulder and the inner endlof the follower, so thatA when the latter is in its place the whole of the rollers aremaintained in their proper lateral position in the cylinder or and the latter, with their rollers, are maintained in their proper position, laterally, on the axle, owing to the enlarged portions of therollers fitting freely between the disks a and-a', on the said axle.
ASmall journals, i i, are formed on the opposite ends of the'rollers, for turning freely in rings E and E', the two rings being connected together vby rods m fm.
It will be observed that no portion ofthe axle bears against the rollers, excepting the 'peripheries of the disks aand a', and that no part of each roller bears against the cylinder, excepting theenlarged portion.
It is essential, in carrying out my invent-ion, that the circumfereuces of the healing-portion of the axle, rollers, and cylinder or box should be properly-proportioned in relationtoeach other.`
Thus, the circumference of the portions d and d of each roller shouldv bear, as near as possible, the same proportion in relation tothe circumference of the disks of the axle, as the circumference of the enlarged portion e of each roller bears to the circumference of thev interior of that portion of the. cylinder against. which the rollers bear, so that the movement of the vportions d of therollers over and in contact with the disks of -the4axle will be in unison with the movement of the enlarged portions of the rollers, over and in contact with the cylinder, or, in other words, so that there can be no frictional drag of the rollers'either against the cylinder or axle.
Iu-the modification illustrated in fig. 3, the axle has but one disk, fitting between two enlargements of the rollers, which bear against the interior of the cylinder 0r box.
This modiiication will be readily understood without explanation, aswill also the proposed arrange ment of the rollers, for a bearing for a'revolvingshaft.
Claim.
An anti-friction box containing' a series of rollers, constructed, adapted, and proportioned in respect to an axle or shaft, and cylinderI or box. substantially as set forth.
In testimony whereof, I have signed my name 'to thisv specification, in the presence of two subscribing witnesses.
