C. H. DENISON, OF BRATTLEBORO, VERMONT.

FELLY-MACHINE.

Specification of Letters Patent No. 31,443, dated February 19, 1861.

To all 'whom t may concern.'

Be it known that I, C. H. DnNisoN, of Brattleboro, in the county of lVindham and State ot' lVermont, have invented a new and Improved Machine for Rounding the Inner Surfaces of Fellies for Vheels; 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 specication, in which- Figure 1, is a side sectional view of my invention. Fig. 2, a. vertical section of the same, taken in the line m, fr, Fig. 3. Fig. 8, a plan or top view of the same. Fig. 4L, a section of one portion of the cutter head taken in the line y, y, Fig. l, and showing the manner of securing the cutters in the head.

Similar letters of reference indicate corresponding parts in the several ligures.

The object of this invention is to obtain a machine by which the inner sides of fellies for wheels may be very expeditiously rounded and the work done in a proper manner, both the sawed and the steamed and bent ellies being operated upon with equal facility.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, represents a framing which may be constructed in any proper way to support the working parts of the machine, and B, is a horizontal shaft which is placed in 'the lower part of said framing, and has a pulley C, on it from which a mandrel D, on the upper part of the framing A, is rotated by a belt E.

On one end of the mandrel D, there is fitted a cutter head F, which is formed of two parts a, Z), each of said parts being a circular disk with a concave periphery as shown in Figs. 2, and 3. The parts or disks a., ZJ, are secured on the mandrel D, by set screws c, which pass through hubs d, of the disks and bear against the mandrel D. The disks a, Z), are not secured on the mandrel D, in contact with each other. A space is allowed between them in which a circular plate Gr, is fitted, the diameter of said plate being about equal to that of the inner sides of the disks a, I). The plate Gr, has a central opening c, through which the mandrel D, passes, the opening being considerably larger in diameter than the shaft, so as to admit of a certain degree of adjustment of the plate. At one side of the plate Gr, there is an arm f, which has a socket g, attached, and said socket is itted on a horizontal rod L, attached to the framing. At the opposite side of the plate there is also an arm t', which rests on a horizontal bar j, attached to the framing, the bar j, being slotted longitudinally, and the arm 2', secured thereto by a screw le, and jam nut Z, the screw admitting of the elevating of the .arm t', and the adjoining side or part of the plate Gr. This will be fully understood by referring to Fig. l.

To the arm f, there is attached by a screw m, a bar' n, having an upright pin 0, at its inner end, which rests on the plate G. A similar bar j), is attached to the arm t', the inner end of the bar being also provided with a pin g, but not resting on the plate Gr, a recess 1f', being made in the plate to allow the bar p, to be depressed. The arrangement of the plate G, with its bars n, p, and pins 0, g, is shown clearly in Fig. 1.

To each part or disk a, b, of the cutter head, cutters H, are attached. These cutters are made of flat plates of steel, having beveled edges s, s, and fitted in oblique slots t, in the disks a, Z). The outer ends of the cutters are made concave to correspond with the peripheries of the disks', and the cutters have a position in the disks tangentially with their hubs, or with circles larger in diameter but concentric therewith. The cutters are secured in the disks c, l), by clamps u, which are simply small slides grooved at one edge to fit over the outer beveled edges of the cutters. A screw o, passes through each slide obliquely into its disk a, or Z), and by being screwed inward causes the clamp to bind the cutter firmly in its slots t, and against its inner edge or surface (LX, see Fig, 4C, so that the latter will act like the cap of a joiners plane iron and insure a smooth cutting action of the cutters. The clamp and its screw and the relation of the former with its cutter will be seen by referring to Fig. 4.

I, represents a semi-circular bed or bearing piece which has two horizontal bars w, 10, at its ends, said bars being slotted longitudinally and having screws a', pass through them into the framing A. This bed or bearing piece it will be seen by this arrangement may be adjusted laterally on the training A, a screw a, being employed tor this purpose, as shown in Figs. 2, and 3.

J, represents a semi-circular bar, the ends ot which are attached to rods b, which pass loosely through the ends ot the bed or bearing piece I, and through guides c, c. On each rod a spiral spring d, is placed, said springs having a tendency to keep the bar J, inward toward the bed or bearing piece I, pins c, which pass through the rods b, controlling the extent ot saidmovement, see Fig. 3.

The operation ot the machine is as tollows: The shatt B, is rotated in the direction ot arrow l, and the'telly to be rounded is tit-ted between the bed or bearing piece I, and the yielding segment bar J, and held in proper position over the cutter head thereby. The pin 0, ot the bar n, is fitted in a spoke hole in the telly and the latten bent down over the head so that the cutters I-I, ot the two disks a, b, will round the inner surtace ot the telly, the latter resting on the plate Gr, which by being adjusted higher or lower by means ot screw 7c, will cause the inner surtace ot the telly to be more or less rounded., The cutters round about halt ot the spaces between the spoke holes in the telly when the latter is retained in one position, and when all the spaces have been thus acted upon, the telly is reversed in position and the remaining parts ot the' spaces 1inished, the telly being shoved along atter each cut so that the spoke holes in the telly will be fitted consecutively on the pin 0. In rounding steamed tellies 'they are shoved along on the head, and the whole telly ot course rounded at one operation, the telly merely requiring to be reversed when one halt ot the spaces are rounded. But in rounding the inner surfaces ot segment or sawed tellies the ends ot the latter are rounded by fitting the spoke holes on pin g, ot the bar p, so that the cutters H, will cut trom instead ot toward the end ot the segment, and thereby avoid the splitting or shelling ott ot the end ot the segment. The tull space between the spoke holes ot the segment telly is rounded in the same way as the sawed telly, to wit, the spoke holes being fitted on the pin 0, as shown in red in Fig. l. The blue telly shows the position ot the telly on pin g, when its ends are rounded.

The bars n, p, may be adjusted as desired on their arms f, z', according to the length ot the spaces between the holes and the bed, or bearing piece I, may be adjusted on the training to suit the thickness ot the tellies to be operated upon. The disks a, ot the cutter head may also be adjusted nearer together or tarther apart on the mandrel D, as may be desired.

Having thus described my invention, what Iv claim as new and desire to secure by Letters Patent, is-

l. -The adjustable plates n, p, provided with the pins o, g, when used in connection with the plate G, and cutter head F, as and tor the purpose set torth.

2. The combination ot the adjustable semi-circular bed, or bearing piece I, and yielding bar J, with the cutter head F, plate Gr, and bars n, j?, provided with the pins o, g, all being arranged tor joint operation as and tor the purpose herein set torth.
