MACHINE FOR DRESSING FELLIES.

SPECIFICATION forming part of Letters Patent N0.320,46'7, dated June 23, 1885.

.Application filed September 2f), 1884. (Model.)

To all whom it may concern:

Be it known that I, WILLIAM GARDNER, a citizen of the United States, residing at Lancaster, in the county of Faireld and State of Ohio, have invented certain new and useful Improvements in Machines for Dressing the Rims of Vehicle-,Wheels5 and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a perspective view of my invention; Fig. 2, a transverse section thereof on line x x of Fig. l; Fig. 3, a detail view of one of the pivoted tables and its attachments, showing them in perspective; and Fig. 4, an under plan view thereof.

The present invention has relation to certain new and useful improvements in machines for dressing the rims of vehicle-wheels, and the object thereof is to provide means whereby the rim or felly of the wheel is perfectly and rapidly dressed; and it consists in the details of construction substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A represents the frame of the machine provided with pulleys a, keyed to longitudinal shafts b, upon the ends of which are faceplates B, having their outer surface covered with sand-paper, emery-eloth, or other like material, which are brought inbeontact with the rim of the wheel. Over the pulleys a pass belts c, which extend down around pulleys d on the driving-shaft e, one of said belts being twisted, so as to give to the pulleys a a rotary motion in opposite directions, and also the face-plates B, the shafts of the pulleys a, as should be understood, being independent of each other. The drivingshaft e has upon one end the usual loose and fixed pulleys to connect it to the mainV driving-belt.

Pulleys f are connected to the shaft e, and connect with pulleys g by belts h, the pulleys g being connected to the ends of shafts t, having their bearings in brackets C, one upon each side of the machine.

The shafts i are each provided at one end with a gear-wheel, k, the teeth of which mesh with those upon a similar wheel, Z, keyed to a vertical shaft, m, by which means the shafts m are caused to rotate in their bearings. The

shafts m extend some distance above the frame of the machine, and vare provided with feedrollers D, which bear against the rims of the wheels, said rollers being of metal or other suitable material.

Each end of the machine is provided with a table, E, pivoted thereto at o, so that the tables can be swung back out of the way to admit the removal of the faceplates B, for the purpose of renewing their surfaces with sandpaper or emery, or replacing them by new ones. The face-plates B can be connected to the ends of the shafts b in any of the wellknown manners so long as it will admit of their ready removal for the purpose above stated. l

'Ihe tables E are each provided with a horizontal bracket, F, which is adjustable to or from the faceplate B by a hand-screw, p, as

shown more clearly in Fig. 4. The screw p,

which I shall term an adjusting-screw, engages with a screw-threaded hole in a lug, r, of bracket F, extending down through an elongated transverse slot, s, in the table E. A

Similar slot, t, is formed in the table E, and upon each side of it has longitudinal flanges passes through the slot to retain the bracket F on the table. Both the lug r and bolt o are pivoted to the under side of the bracket F, so as to admit the latter moving horizontally upon the arc of a circle, as necessity requires.

To the front edge of the bracket F is hinged what I term a head, G, which is adapted to be adjusted from an upright or vertical position to an angle either forward or backward by means of the slotted plate H. One end of this plate H is hinged to the back of the head G, while the opposite end is connected to a block, w, upon the bracket F by a set-screw, w. Thus it will be seen that the head G can be set at any desired angle from a perpendicular by the hinged slotted plate and set-screw.

Upon the front face or side of the head G are pivoted bearing-plates I J, the upper one of said plates being adjustable to or from the a, to adapt the slot to a T-shaped bolt, @,which IOO lower plate, so as to increase or .diminish the space between them for rims of different sizes. The inner edges of the plates I J are of shape to correspond with the curve of the rim, and the means preferably employed for adjusting the plate I is by a slot and set-screw, as shown in Fig. I. The rim of the Wheel to be acted upon by the face-plate B is placed between the bearing-plates I J, and the proper adjustments made of the bracket F and head G.

When the machine is set in motion, the feedrollers D will force the rim through the space between the plates I J, which I term abrading-wheels,77 the lower one of said plates or abrading-wheels automatically adjusting itself to any irregularities in the rim, the emery or sand-papered surface of the face-plate as it is revolved in contact with the rim effectually dressing it.

In order to render the adjustable bracket automatically yielding a curved spring, K, is employed, which is connected to the upper side of the table E, its opposite or free end bearing against the back edge of the bracket. The tension of the spring K is regulated by a thumb-screw, L, Which bears against it.

I have shown my machine as being double, or its operating parts duplicated, so as to dress two rims at one and the same time; but I do not desire to confine myself thereto, as the machine may be made singly to dress one rim only.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine fordressing the rims of vehicle-Wheels, the combination, with a revolving abrading Wheel and a revolving feedroller, of a head provided With adjustable and pivoted bearing-plates, between which the rim is held, substantially as and for the purpose set forth.

2. In a machine for dressing the rims of vehicle-Wheels, a revolving face-plate or abrading-Wheel and a feed-roller, in combination With an adjustable head carrying pivoted and adjustable bearing-plates connected to its front ide, substantially as and for the purpose speci- 3. In a machine for dressing the rims of vehicle-wheels, a revolving abrading-Wheel and feed-roller, in combination with a head hinged to an adjustable bracket, and provided upon its front side with pivoted and adjustable bearing-plates, between which the rim is held While being operated upon by the abrading-Wheel, substantially as and for the purpose described.

4. In a machine for dressing the rims of vehicle-wheels, a revolving abrading-wheel and feed-roller, in combination with a pivoted table, having connected thereto an adjustable bracket provided with an adjustable head, the latter provided With pivoted and adjustable bearing-plates, substantially as and for the purpose set forth.

5. In a machine for dressing the rims of vehicle-Wheels, the combination, with a revolving abrading-Wheel and feed-roller, of a piv-V oted table, a bracket carrying a head having bearing-plates, and means fork adjusting, respectively, the bracket and head, consisting of a hand-screw engaging with a screw-threaded hole in a lug connected to the under side of the bracket and extending through a slot in the table, and a hinged slotted plate, and set-screw connected to the head, and a block projecting from the bracket, substantially as and for the purpose described.

6. In a machine for dressing the rims of vehicle-wheels, the combination, with a pivoted table carrying an adjustable bracket and head, the latter having pivoted and adjustable bearing-plates, of means for rendering the bracket automatically yielding, consisting of a curved spring bearing against the back edge of the bracket and having its tension regulated by a thumb-screw, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.

WILLIAM GARDNER.
