MODE OF CONSTRUCTING HUBS FOR THE WHEELS F CARRIAGES, 86C.

Speccaton forming part of Letters Patent No. 448, dated October 28, 1887; Reissued September 25,1s3a1v0; 14. Y l

. 'riages are attached to and held on thev arms of the axletree, and, secondly, in providingv a chamber between the hub andthe arm of the aXletree for the -reception and holding of the oil and keeping it free from the intrusion of dust and dirt of any kind-which said improvements are described and may be constructed in the following manner, that is to say:

The first-the mode or means by which castiron hubs and the wheels of carriages are attached to and held on theA arms of the axletree-is effected thus, (see annexed drawings makingY part of this specification.) On the arm, B, of the axletree, at the same distance from the end of the arm as the length of the bore in the hub, a groove G sufficiently wide for the insertion of a metal washer D and a leather washer' E is turned, leaving between the washers and a shoulder inside of the hub a projecting band or shoulder H on the arm of the axletree itting the bore in the hub from the inner end of the hub to the shoulder inside of the hub. Over these washers a metal screw cap or band C with a hole in the center of the cap to admit the passing of the arm of the aXletree through the cap or band, screws on to the inner end of the hub, and by embracing within it the 'washers inserted in their groove, retains and holds securely the hub and wheel on the aXletree-the inner end of the hub having a screw cutl on it to t the screw turned in the inside of the cap or band--the metal washer D is made in two pieces, each piece forming nearly .a semicircle of uniform thickness `except at the lapping end which is of half the thickness of the other part, so as to make the two ends when lapped together of the same thickness as the other parts, a rivet R being inserted through the two ends when lapped forms a rule joint by which the washer can, whenthe cap or band x is unscrewed and moved o from the hub, be opened taken olf from the arm of the axletree and another substitutedin its lace when required without taking the hu olf from the aXletree.

by boring from the shoulder/ inside..the-

diameter an eighth or a quarter of an inch.

largerthan the remainder iof the bore which is to be-continued to within a quarter or anY eighth of an'inch of the outer end of the hub, that end being left closed-the arm of the aXletree being turned of a diameter to it'the bore in the hub from the inner end of the hub to a point an half inch short of where the line of the inner edge ofthe spoke mortise if continued to the aXletree would meet the aXletree, at which point it is suddenly diminished to a diameter iitting the smaller bore within the hub. rlhis leaves the space between the vinside of the hub and the circumference of the axletree andthe points where the smaller diameter of the aXletree and the smaller borein the hub commence, suiiicient'to contain the neca ,essary quantity of oil--andy the outer end required, and is closed effectually' by a screw` stopper at all other times. j

Now therefore I, the said HOWARD DE- :LANO, do specify and claim as my invenytionv First, the mode or means by which castiron hubs and the wheels of carriages on the yarms o-f the aXletree are attached and held securely by the insertion of jointed washers in a groove on the arm of the aXletree and the screw cap or band embracing within it the washers and screwing on the'inner end -of the hub in the manner before described.

In witness whereof l have hereunto sub-v scribed my name the 29th day .of August, fin the year of our Lord one thousand eight hundred and thirty seven.
