IMPROVEMENT IN HUBS FOR CARRIAGE-WHEELS.

Specification forming part of Letters Patent No. 122,322, dated J anna-ry 2, 1872.

To all whom it may concern:

Be it known that l, J AGCB KRITGH, of Cleveland, inthe county of' Cuyahoga and State of Ohio,haveinven ted acertain new and Improved Carriage-Wheel 5 and I do hereby declare that the following is a full, clear, and complete description thereof, reference being had to the accompanyin g drawing making part of the same.

SPECIFICATION.

ridge-wheel hub, and the special object of said invention is to provide a neat, simple, and secure way of fastening the wheel to the axle by means of a circular plate fitted to and in contact with the posterior side of the collar of the Iaxle, 'and which plate is then bolted to a iiange on the inner end of the, hub, a more full and complete description of which is as follows:-

The hub referred to consists, in part,'of two sections, A B, Fig. 2, each of which has a wide flan ge, O, between which the base of the spokes D are litted in mortises cut in the wooden core Etted snugly to the inside of the two sections, as shown in Fig. 3, in which a shows the tenons itted in the wooden core. The sections A B are'secured to each other and to the sides of the spokes by bolts or rivets b, whereby said spokes are ystronglybraced in a lateral direction. F, Figs. 3 and 6, is the axle-box in which the axle or spindle G is fitted. H is the axlecollar. l is the enlargement before the collar and J the enlargement behind the collar. The enlargement I is fitted in the axle-loox, whereas the enlargement J is fitted in the circular plate K. It will be observed that said plate is provided with a rim or narrow iiange, K Fig. 5, on its inner side, whereby is formed a recess, k, in which is fitted half the thickness of the leather washer O. It will also be seenthat sec.

tion or thimble B is provided with a flange, L, Fig. 3, and that around the edge of said iiange is a rim, B', whereby is formed a recess, b, Fig.

c, in which is r11-.ted the other naif tte thieknessof the leather washer 0. In the bottom of said recess is fitted the collar H ofthe axle, so that the posterior side thereof is iiushed with the face of the liange-L or bottom ofthe recess b, in which the washer 0 is fitted. i The plate K,when adjusted to the `iian ge L, forms therewith a chamber in which is contained a washer, O, referred to, which lits closely but not tightly both the side ofthe collar and the bottom of the recess b, `and also the face or bottom of the recess in the plate K, and which is secured to the flange L by bolts c or their equivalents. The purpose of the vwasher 0 interposed between the side of the collar and the plate K is to prevent the two m etal surfaces from contact and thereby protect them from frictional wearing, and also to prevent them from rattling. Between the anterior face of the collar and the end of. the axle-box in which it is iitted is interposed a leather ring or washer for a similar purpose.` From the above description and illustration it will be seen that the hub or wheel is retained upon the axle by means of the plate K, being bolted or otherwise secured to the flange L, forming a part of the hub, which7 being on the anterior side ofthe collar and the plate on the opposite side, renders it impossible for the wheel to come oil' from the axle, unless the bolts c are first removed, thereby detaching the plate from the hub.

By this means a simple, neat, and secure connection is made of the wheel to the axle, and which can be easily and readily removed therefrom for oiling or for other purposes by simply removing the bolts c, which will allow the wheel to slip from the spindle or axle. This manner of securing the wheel to the axle effectually excl'udes dirt and dust from the axle-box; hence the wheel will run smoothly and with but little frictional wearing. It will be observed that the end of the spindle is hollow, the purpose of which is to hold oil or grease in reserve, from which the spindle is self-supplied, and that in the side of the axle is cut a` groove, c, Fig. 4,

for conducting the oil along the spindle, said groove havin g a communication with the chamber inthe endof the axle by'means of a small4 hole, f, Fig, 4. lt will be observed thatthe bolts c, whereby the plate is connected to the flange of the hub, also pass through the washer O;

hence, said .washer is held securely inplace.

The collar H is of large diameter, whereby is obtained more strength and endurance to the A attachment of the Wheel to the axle, as the large size ofthe Collar more effectual] y pre vents twisting or wrenching of the Wheel on the axle than a collar of small diameter; hen'ee the Wheel Will run with more steadi ness and With less frictional Wear than if the collar were of small diameter, as they usually are in this class of hubs.

C lafims.

lewithin said rim, flange L forming part of the thimble or ysee-tionA and provided with a rim, B', and recess b', as arranged in relation to the Washer 0, axle Gr, as applied to a Wooden hub y conjointly, substantially as and for the purpose set forth.

2. The Wheel seouredto the axle by means of the plate K arranged on the posterior side of the collar H and connected to the lian-ge L of the hub by screw-bolts or their equivalents with the collar H in the chamber of the llange L, as applied to Wooden hubs, in the manner and for the purpose substantially as set forth. 3. The circular plate K in combination with the flange L when said flange forms a part of the thimble or sentieri A, all arranged in combination With a Wooden hub, substantially in the manner as described, and for the purpose set forth.
