HU-CAPLOCKING DEVICE.

Application led September 4, 1919. Serial No. 321,574.

To all whom t may `cof/wem:

'Be it known that I, --EDWARD G. BUDD, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Hub-Cap-Locking Devices, of which I declare the following to be a full, clear,\and exact description.

This invention relates to improvements in hub cap locking devices for demountable wheels.

One of the objects of my invention is to provide an improved locking device for the hub caps of demountable wheels which is simple in construction, fool-proof in operation, locks the hub cap positively to the inner hub and is ofsuch a nature as not to detract from'the artistic appearance of the hub cap.

Another object of my invention is to provide a hub ca of simple construction having a locking evice which can be manufactured in large quantities at a' comparatively low cost.

Another object of my invention is to provide a hub cap locking device of such a nature that the hub cap may be screwed up by hand, but will be locked against rotation to unscrew the hub cap, except when the hub cap wrench is properly applied.

Further objects, and objects relating to economies of production and operation and details of construction, will definitely appear from the detailed description to follow. I accomplish the objects of my invention, in

. one instance, by the devices and means described in the following specification. My invention is clearly delined and pointed out in the appended claims. A. structure, constituting a preferred embodiment of my invention, is illustrated in the accompanying drawing, forming a part of this specicationz in which:

Figure I is a transverse, sectional view through the hub of a demountable wheel embodying my invention.

Figure II is a transverse, sectional View through the hub cap taken on the line 2 2 of Figure I.

Figure III is a transverse, sectional view through the hub cap taken on the line 3 3 of Figure I.

Figure IV is a view of the outer end of the hub and hub cap corresponding to Fig- Flgure V is a view corresponding to Figure'II but showing the wrench applied to release the latch.

In the drawings, similar reference numerals refer to similar parts throughout the several views and the sectional views are taken looking in the direction of the little arrows applied to the section lines.

Considering the numbered parts of the drawing, I have shown a demountable wheel comprising the inner hub 15 and the outer hub 18. The axle shaft 11 extends within the usual axle casing 10, upon the outside of the end of which the bearings 12 are mounted. A bearing retainer 13 encloses said bearin s and has a radially extending flange to Whlch the brake drum 14 is bolted by bolts which also` extend through a radial flange on the inner end of the inner hub so that the brake drum, the bea-ring retainer, and the inner hub are bolted together, with the bearing, and the bearing retainer housed within the inner end of the inner hub, as shown in Figure I of the drawing. The outer end of the inner hub is cylindrical or cup-shaped in form and internally threaded, and a plurality of bevelled ratchet teeth 17 are formed on the inner surfacel of the cup-f An outer hub 18 is removably mounted on v the inner hub 15 and provided with pressed out seats 19 and 2O for the ends of the spokes. Any suitable intermeshing means are provided to prevent relative rotation of the outer and inner hubs.- The outer end of the outer hub 18 is bevelled at 21. In Figure I of the drawing, I have shown a rear wheel, the inner hub being so formed so as to be mounted on the rear axle. It is to be understood, of course, that my invention is body portion, and the inner face of said head has a bevelled surface engaging and co-operating with the bevelled end 21 of the outer hub. An opening is provided through the side wall of the body portion 23 of the hub cap between the inner face of the head and the threaded portion of said body, and there is also provided an opening 24 through the side wall of the head in line with the previously described opening through the side wall of the body. A latch 25 is mounted within the hub ca and has a bevelled tongue 27 which is slidaby mounted in the opening through the side wall of the body portion of the hub cap and engages the internal bevelled ratchet teeth 17 of the inner hub as clearly `shown in Figure III. The latch 25 also has an actuating pin 26 which is slidably mounted in the opening 24. rIhe tongue 27 and the actuating pin 26 extend laterally from the latch 25 at substantially fright angles thereto. A guide pin 28 extends from the latch 25, in the opposite direction from the tongue 27; and is in line lwith a similar ide pin 30 which extends `laterally from t e side wall of the hub cap at a int diametrically opposite. A compresslon spring 29 is compressed between the latch 25 and the side wall of the hub cap, the ends of said spring being centered around the pins 28 and 30.

To. rotate the hub cap, I use a wrench 31 Y having a shoulder 32 and a curved arm 34,

from the end of which a pin 33 projects latorally; When it is desired to rotate the hub cap, the pin 33 is inserted in the openin 24,

and the shoulder 32 engages the side o the head of the hub cap, thus giving the wrench a grip on the hub cap by means of which it may be rotated. The insertion of the pin 33 in the openin 24 presses back the actuating pin 26 an the latch 25 against the pressure of spring 29, thus withdrawing the bevelled tongue 27 from engagement with the bevelled ratchet teeth 17 so that the hub cap may be rotated freely. As soon as the wrench is removed, the spring 29 presses back the latch so that the tongue 27 moves into enga ement with the ratchet teeth, the bevel of t e tongue 27, .and of the ratchet teeth 17, being such as to permit the rotation of the hub cap in a direction to screw up the hub cap, while preventing all rotation in the opposite direction. rIhe end of the actuating pin 26 is normally substanthe operation of this locking device and1 further description is unnecessary. Itis apparent that it may be made of few parts, and

opening.

meente readily yields itself to embodiment in a hub in the use (if this type of locking device, the outer end or head of the hub cap may be cylindrical and of very substantial appearance, so that this construction does not detract from the artistic appearance of the hub cap.

I am aware that the articular embodiment of my invention, which I have shown and described here, is susceptible of considerable variation without departing from the spirit thereof, and, therefore, I desire to claim the same broadly, as well as specificall as indicated b the appended claims.

I-aving thus descri ed my invention, what I claim as new and desire to secure by Letters Patent, is

1. A device ofthe class described comprising the combination of an inner hub, an outer hub removably mounted thereon, a hub cap detachably mounted on one of said hubs and havin y an uninterrupted surface engaging the ot er to hold said hubs in engagement, said hub cap having a pair of transverse alined openings through the side wall thereof, and a latch having a tongue slidably mounted in one of said openings and an actuating pin slidably mounted in the other 2.
