, y Metallic Hub. Nq 112,452.1 A Patented' March 7, 1871.
N UNITED STATES JOHN" H. HARPER, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN METALLIC HUBS.-
VSpecifcationforming part of Letters Patent No. 112,452., dated March?, 1871.
`To a/ZZ whom it may concern:
Be `it known that I, JOHN H. HARPER, of t Pittsburg, in the county of Allegheny, and in the State of Pennsylvania, have invented cer tain new and `useful Improvements inMetallic Hubs; and I do hereby declare that the following is a full', clear, and exact description thereof, reference being `had to the accompanying drawing, and to the letters of reference marked thereon, making apart of this specification.
The nature ot' `my invention consists in the construction and arrangement of a metallic hub, as will be hereinafter more fully set forth. In order to enable others skilled in the artA i towliich my invention appertains to make and usethe same,I will i now proceed to describe its construction and operation referring to the annexed drawing, which represents a lon-` gitudinal vertical section of my improved me- A represents the box, which is screwed into `the back flange, B, and, if necessary or desired, the said flange and box are connected orsecured together b y a set-screw, a." rIphe spokes 0C are held between the back flange,
i. Hand the front flange, D, and are secured f iirmly by bolts or rivets b b, which pass through said anges betweeufthe spokes, or, rather',
one-half of the bolt is in each of the two'adjoining spokes. The spindle E passes through thebox A, and is at its outer end provided i with a` nut,d which is partially within an enlargement at the outer end of the box. This wouter end of the box is closed by a cap, G, as
shown.
Within the box A, immediately under the spokes and outer flange, is formed an oil-oham ber, f, as shown.
The main difficulty with ironhubs has been in the box cutting or wearing out, `when the Wheel was rendered worthless, as there was no way of getting 1n anew box. My box'is screwed `into the back iiange, so that if it cuts out it can be taken out and another put in without injury to the wheel.- These boxes are made to screw right and left, so that in running they will tighten. i
Forlsai'ety I may use the set-screw a, although this is not absolutely necessary. The hole through which this screw is inserted passes clear through into the bore of the box, so that the wheel may be greased without removing the wheel from the spindle. "The cap on the end prevents the escape of the grease.V
Having thus fully described my invention,` what I claim as new, and desire to secure by Letters Patent, is-` In combination with the spindle E, the box A, with oil-chamber f, screw-flange B, with oil-passage and screw a, the spokes C C, flange D, and bolts b b, all substantially as and for the purposes herein set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 14th day of January, 1871.
JOHN H. HARPER.
