WHEEL.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Original application filed March 17, 1902, Serial No. 98,634. Divided and this application filed March 16, 1904. Serial No. 198,350.

To all whom it 19a/ty concern:

Be it known that I, HENRY H. PORTER Jr., a citizen of the United States, residing at Ohicago, in the State of Illinois, have invented certain new and useful Improvements in Wheels, of which the following is a specification.

My invention relates particularly to wheels designed to run alternately upon a rail or upon a plane surface. The devices herein described constitute a division of my prior application No. 98,634 filed March 17 1902, and the objects of the present invention are, to provide a shiftable wheel flange which may rotate either with the tread of the wheel vor independently therefrom; to provide a superior mounting of the flange upon the axle and superior means for throwing it into and out of operation; to provide a superior mounting of the wheel upon a pivoted arbor on the end of' the axle, and to generally improve the structure and operation of such wheels. These objects, and other advantages to hereinafter appear, I attain by means of the construction illustrated in preferred forms in the accompanying drawings, wherein- Figure 1 is an inside elevation of a wheel embodying my improvements in a form having positive means for shifting the iiange bearing;

Figure 2 is an edge view or elevation looking from the left of Figure 1 with the handle of the lever removed and portions of the rim broken away;

Figure 3 is a vertical transverse section through the wheel with the ange in operative position;

Figure 4 is a plan view of a portion of Figure 1 showing the apparatus for moving the ange;

Figure 5 is an elevation taken from the right of Figure 2 showing details of the ange shifting mechanism;

Figures 6 and 7 are respectively, a partial inside elevation, and a transverse vertical section, of a modified form of my wheel in which the flange is directly attached to the wheel, and the wheel and flange are both mounted upon a pivoted knuckle or arbor upon the end of the axle;

Figure 8 is half of an outside elevation of the wheel of Figure 7. the line (7) therein showing the section of Figure 7;

Figure 9 is a partial edge view and partial section of the same wheel showing the flange elevated out of operative position;

Figures 1() and 11 are detail views showing parts of locking mechanism, the latter figure being a vertical section showing a modified locdllring means for the iiange bearing sleeve, an

Figure 12 is a view similar to the latter but showing a different arrangement of bearing on the axle.

Referring rst to Figures 1 to 5 inclusive, it will be seen that I have therein shown a wheel 13, which is provided with a flangedisk 14 separate from the wheel, and mounted to rotate about a sleeve or disk-center 17, which surrounds the axle 15, and is constructed with a slotted opening 18 to permit it to be raised and lowered when it is desired to raise or lower the flange-disk 14, the sleeve 17 being also provided with a pivotal support 24 and an extension 25, forming a handle whereby thesleeve may be raised or lowered by lever 26 in shifting the flange-disk 17. The pivotal support 24 of the sleeve having engagement with the bracket 23 formed as an extension of the casting 16, prevents any rotative movement of the sleeve around the axle, while at the same time permitting the same to be raised and lowered as described.

When the parts are in the position shown in Figures 1, 2, and 3, it is evident that the iiange is concentric with the wheel, and is in effect a flange for the wheel similar in all respects to the iiange employed on wheels of this character in railway transportation. When in this position the iiange and wheel are secured relative to each other by means of the locking block 19, which is pushed into the recess 18 below the axle in the position shown, by means of the spring 27, shown more clearly in Figure 2, acting on the lever 21 which engages block 19 by pin 20 and is pivoted on a pin 22 on the axle bearing bracket 16.

In the mechanism shown in these gures, when it is desired to raise the flange-disk to bring it out of operative position, the lever 21 is moved against the resistance of the spring 27 and pin 28, to pull the block 19 out of engagement with the sleeve 17, when by the lever 26 the sleeve 17 is raised, carrying with it the flange disk 14, the amount of raising motion being sufcient to bring the disk high enough so that the edge of the flange will be IOO out of contact with the ground and the wheel free to run upon its tread surface without interference from the flange. In this form of the wheel, I have not indicated any special means of connection between the flange-disk and the wheel, this being unnecessary on wheels of relative small diameter, but in some instances I prefer to directly connect the wheel and flange, as shown in Figures 6 to 12.

In this modification designed for large wheels, it will be seen that the wheel 29, the flange 30, and the bearing sleeve 17 are much the same as before, except that the wheel and flange are connected otherwise than by means of the axle. rI`he wheel is provided on its web with a hollow ridge 35 preferably cast with the wheel and providing a channel which opens through the annular slot 35n to the inner side of the wheel. A series of bolts 36 extend through this slot and engage the radial slots 38 in the flange by means of the squared bearing heads 37 which rest thereon as shown in Figure 6. The nuts of the bolts may be covered by an annular guard 39 when desired. At one point on the annular slot of the wheel there is provided a screw plug 40 which may be taken out for the purpose of introducing the bolts 36, it being' understood that these bolts may travel around through the entire circumference of the slot 35. rlhis thoroughly clamps the wheel and flange together at points outside of the bearing and yet at the same time allows of independent rotation of the two parts and also radial variation in their position so as to suit the conditions of travel so that the wheel and flange (which are of different diameter) are not required to revolve at the same rate.

In the form of the improvement shown in.

these figures it will be seen that the axle 32 is in the form of an arbor which is pivoted to main axle 33 by head 34, and in place of apin to engage the slot in the bearing sleeve 17 I provide on its surface a pair of lugs 41 as shown in Figure6 which, when the wheel is in operative position, are moved down and catch under the snap hook 42 (see Figure 9), which is pivoted at 31 on the head 34 of the knuckle and is pressed inward by a spring' to engage the lugs 41. Theselugs also engage the sides of head 34 to prevent revolution of the sleeve. A preferable means of fastening the flange in place however, is that shown in Figures 11 and 12, comprising a springpressed bolt 43 whose operation will be apparent from said figures. In this form of the bearing sleeve 17 thelugs for preventing it from rotation by engagement with the sides of the head 34, may be avoided by reason of the fact that the pin 43 will prevent the sleeve from rotation. It will be understood that when the hook 42, or the pin 43, is withdrawn the contact of flange '30 with a plane surface will automatically raise the flange, and either lock it in raised position in the case of bolt 43 or merely allow of its being supported continually by the floor and dropping downA when entering the slot of a track. 'Ihe bolt 43, or the hook 42, or in the form of Figure l, the lever 21, may be operated manually, or by automatic means as shown in my prior application, as may be preferred.

Having thus described my invention and illustrated its use, what I claim as new, and desire to secure by Letters Patent, is the following:

1. The combination of a wheel and non-rotative axle, a flange disk, a bearing sleeve for the disk engaging the axle by an elongated slot, and locking means therefor, the flange disk being movable Aindependent of the wheel in turning.

2. The combination with an annular slotted wheel, of a flange attached thereto by bolts working in the slot, and means for shifting the flange on the wheel into and out of operative position and locking it in either position.

3. The combination of a wheel provided with a circumferential slot or groove, aflange attached to said wheel by bolts in said groove and mounted on a movable sleeve on the axis of the wheel for shifting the said flange vertically and means for locking said sleeve in place, whereby said flange may be thrown into and out of operative position and may revolve relatively to the said wheel.

4. The combination with a wheel and a fixed axle, of a movable hub upon said axle, a flange upon said hub, and means foi` shifting the hub to throw the flange into operative position,said hub being provided with a slot and a pin for engaging said slot to hold the eccentric in place.

5. The combination with a wheel of a shiftable flange attached thereto and mounted upon an eccentric hub, said hub being provided with lugs permitting a vertical motion but preventing a revolution thereof, and means to hold the hub in raised position.

6. The combination with a wheel and axle, of a shiftable flange mounted upon a movable hub on the axle, means for shifting the hub and a slot in the hub and co-operating bolts engaging said slot to prevent the hub from moving, substantially as described.

7. A wheel provided with a flange disk of greater diameter, said flange disk being' attached to the wheel outside the axle by means allowing independent movement of the wheel and flange disk.

8. A wheel provided with a flange disk of greater diameter, said flange disk being attached to the wheel outside the axle by means allowing independent movement ofwheel and flange disk, and means for shifting the flange out of operative position.

9. The combination of a fixed axle, a wheel, a shiftable flange disk, a vertically movable bearing sleeve for the disk, and means directly IOO IIO
