MACHINE FOR SPINNING CAR-WHEELS.

SPECIFICATION forming part of Letters Patent No. 581,284, dated April 27, 1897.

Application filed September 6, 1895. Serial No. 561,650. (No model.) I

To aZZ whom it may concern:

Be it known that 1, JAMES HENDERSON, a citizen of the United States, residing at the city of Three Rivers, in the county of St. J oseph and State of Michigan, have invented certain new and useful Improvements in Machines for Spinning Car-Vheels, of which the following is a specification. I

My invention relates to improvements in metal-spinning machines, and more particularly to a spinning-machine for spinning carwheels of thick sheet metal or plates.

As heretofore constructed machines of this class have been difficult of adjustment. It has been difficult to control the same to secure the desired results, and the shaft of the spinning-wheel has been more or less likely to become inclined, which prevents its doing good work.

The objects of my invention, therefore, are, first, to provide a machine which is positive and powerful in its action; second, to provide means of adjusting and carrying the spinning-wheel so that it shall move to exactly the desired position; third, to provide improved means of controlling the movement ofthe spinning-wheel, so that it shall be entirely automatic in its act-ion or can be controlled by the operative at will; fourth, to provide an improved spinning-machine for spinning car-wheels of sheet metal where the rims are of irregular form.

Other objects and improvements in the machine will appear clearly in the detailed description of the same.

I accomplish the objects of my invention by the machine and mechanism shown in the accompanying drawings, in which- Figure 1 is a top plan view of a spinningmachine embodying all of the features of my invention. Fig. 2 is a front elevation of the machine shown in Fig. 1 with a portion of its frame broken away and the guide-wheels removed. Fig. 3 is an elevation of the machine taken from the left hard of Figs. 1 and 2, being an end elevation of the machine. Fig. 4 is an enlarged detail sectional view of the hydraulic cylinder and its connections for actuating the spinning-roll, taken on line 2 2 of Fig. 1. Fig. 5 isasectional View taken on line 5 5 of Fig. 4, looking down. Fig. Sis

an enlarged detail view of the parts essential to the spinning of irregular-formed carwheels, taken from Fig. 2. Fig. 7 is an enlarged detail sectional view on line 7 7 of Fig. 6, looking in the direction of the little arrows at the end of the section-line. Fig. 8 is a transverse sectional view taken on line 8 8 of Fig. 6, looking down. Fig. 9 is a sectional view of the cross-head and its connections to the piston-rod of the hydraulic cylinder, taken on line 9 9 of Fig. 4, looking in the direction of the little arrows at the ends of the section-line. Fig. 10 is an enlarged detail sectional view of the adjustable eccentric 7t, appearing clearly in Figs. 4 and 5. Fig. 11 is a sectional View on line 11 11 of Fig. 10, looking in the direction of the little arrows at the ends of the section-line. Fig. 12 is a vertical sectional View of one of the guidingrollers of the spinning-machine, taken on line 12 12 of Fig. 1, looking in the direction of the little arrows at the ends of the sectionline.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the leti ered parts of the drawings, A is the base which supports the remainingpart-s of my improved machine. B B are side pieces projecting up therefrom, which support the top or table-like portion 0, which is adapted and formed to answer its peculiar purpose. To the rear of the machine are upwardly-projecting brackets B B, which afford bearings to carry the driving-shafts of the machine. The inner bracket 13 is also secured by suitable bolts to the rear end of the table portion O and serves as a support for that part of the machine. Between the side pieces B is supported a central lower table or plate 0, which is parallel with the top plate 0.

The counter-shaft M is supported in suitable boxes on the bearings B B to the rear of the machine and bears the usual tight and loose pulleys h for operating the machine from suitable belt connections. Extending longitudinal of the base and supported in suitable boxes D D therein is the drivingshaft of the machine D, which bears a large gear-wheel D, which meshes with the pinion M above and serves to actuate the entire machine. A vertical shaft G extends up through the rear portion of the tables 0 and C and bears a suitable bevel-pinion at the bottom, which meshes at that point with a bevel-gear E on the shaft G. This shaft G is permanently held in position and bears the female spinning-roll L, which is supported above the top of the table (3. In a suitable housing or frame F is supported a movable vertical shaft II, which bears at its upper end a male spinningroll II, the housing F being movable back and forth over a space of about three inches in suitable guideways, which permits the roll to be moved out and in for the purpose of spinning the car-wheels between the two rolls L and H.

From the top plate 0 to each side of the spinning-rolls are guiding-rolls '1, which are supported in suitable slots and are adjustable to and from the spinning-rolls to properly guide the rim of the car-wheel of any size to the same, so that it shall be spun true by be ing guided in this way. The guiding-rolls are adjusted close to the spinning-rolls when a small car-wheel is being spun and moved farther away when a larger wheel is being spun, the points of contact with the two guiderolls and the point of contact between the two spinning-rolls determining the circle of the periphery of the wheel.

On the driving-shaft D below is a suitable bevel-gear E, which meshes with the bevelpinion on the lower end of the shaft H. A bracket from the housing or frame F extends downwardly and a journatbearing box is formed thereon to hold a suitable sleeve which is integral with the bevel-gearE. The bevelgcar E is movable along the shaft D, along a suitable key 1 which fits into a key-seat in the gear E and its sleeve, which permits of the required motion and holds the gear E in mesh with its follower on the lower end of the shaft II, which appears clearly in Fig. at.

Between the plates 0 and O is supported a hydraulic cylinder R by suitable bracket p tojections therefrom. In the cylinder R is a suitable hydraulic piston It, from which extends a piston-stem R, which is connected by a suitable cross-head with the housing or frame F by a suitable mechanism for actuating the same. This connection from the cross-head of the piston R to the housing or ported in suitable bearings in the top plate C above and in suitable bearings on the intermediate plate G below, parallel with each other in substantially the same vertical plane.

Suitable shafts project transx'ersel y with the machine through the upper and lower part of the housing F, and the upper shaft is connected to the upper shaft 7;; by a suitable toggle-joint U U, and the lower shafts 7a and are similarly connected by a similar joint, the joints being adapted to fold toward each other between the top plate 0 and the intermediate plate 0, the toggle-joints being equal andthe shaft-s j and 7.: above and below being the same distance apart and in planes parallel to each other.

On the forward end of the piston-stem R is a suitable cross-head, standing in the vertical position, which is connected by links Q Q to the central joint of the toggle-joints U U above, and below by pins 11, which are suitably secured to the cross-head.

To the ends of shafts P, which are supported by suitable hangers from the top plate 0 and by suitable brackets from the intermediate plate C, are secured levers P, bearing segments of gear which project up from the lever below and down from the lever above and mesh in a line opposite the outer end of the piston-stem It. The outer ends of the upper lovers are connected by suitable links Z to the shaft j, and the cutter ends of the lower levers are connected, also, by similar links Z to the lower shaft 7'. The levers P 1 and link Z are exactly s 'nnnetrical to each other and equal.

By examining Fig. at it will be seen that when the water is admitted to the hydraulic cylinder B it will carry the piston-head R forward, which will. actuate, through the links Q Q, the togglejoints U U U U, which will carry forward very powerfully the frame or housing F, which will carry its spinningroll II forward against the spinning-roll L, the spinning-rolls being actuated from the driving-shaft, as heretofore described. As the joints which actuate this spinning-roll II are toggle-joints, the force with which the spinning-roll is carried forward is very great. The connections from the shaft j through the levers I, which mesh with each other, prevent any nnequal motion of the top and bottom of the shaft II and serve to actuate the same in exactly the vertical position after the vertical shaft H has been once adjusted to that position.

The adjustment of the connection to the housing F for adjusting the shaft is accomplished by a disk 7;, supported on the shafts 7t above and below, and by rotating the same it will be noticed that as the bearings are eccentric the bearings of the rear ends of the links U will be carried backward and forward to any required extent for securing a proper adjustment, and when the set-screw is turned into the aperture 10 on the periphery of the disk 75 (see Figs. 10 and 11) the same will be held very securely and with very little strain at that point, owing to the fact that the bearing-support is eccentric, and consequently does not yield easily to the pressure. A shaft 7t extends through the central portion of the housing or frame F, and to the outer ends of this shaft 71 are secured cables Z, which pass ICO ICS

suitable weight mis supported from a pulleym, which hangs in the loop of the cable Z and returns, by its weight, the cross-head and housing to the normal position after the machine has been actuated. On the bottom of the cylinder R is secured a suitable hydraulic valve S for delivery of water under pressure to the hydraulic cylinder from the supplypipe 12, and it also allows water to exhaust from the cylinder through the exhaust-port n. The valve-stem 19 projects downwardly through a suitable guide in the intermediate plate 0. In the lower part of the stem is contained a notch 19, which is engaged by a suitable slide as, which is carried to place by a coil-spring az. On the intermediate plate 0 is supported a small lever 25 on pivot 25, the lower end of which is adapted to engage the inner end of the slide as. The upper end bears a suitable adjustable set-screw t, which projects inwardly toward the inside of the cylinder R and at such a point as to be engaged by the piston-head at the outer end of its stroke. A suitable lever r is pivoted to the under side of the intermediate plate 0 and engages at its outer end in a mortise in the stem 23 to the slide-valve. At its inner end it bears a weight 0" and is connected by a link 3 to a foot-lever s, by which it may be actuated. By stepping on the foot-lever s the link 3 will be raised, which will raise the inner end of the lever r, carrying the outer end down, which will depress the valve-stem p and allow it to be engaged by the slide a; in the notch 19. This will operate the valve and the machine.

It will be noted when the piston R moves forward to actuate the housing which carries the spinning-roll that at the inner end of its stroke it will come in contact with the setscrew 25, which will actuate the lever t, which actuates the slide 00, and release the valve-stem p and allow the weight 0 to carry up the valve and allow the water to exhaust from the cylinder. Then the weights m will carry the entire apparatus back to the normal position. \Vhen the operative desires to again actuate the machine, he merely steps on the lever s, more water is admitted to the hydraulic cylinder, and the same process is again repeated.

If the car-wheels are very hot and roll very easily, which may cause irregularities in the rim of the same, or if for any other reason irregularities occur in the rim which it is desired to roll or spin further, the operative continues to hold his foot upon the trip-lever s, which will not permit the water to exhaust from the hydraulic cylinder, and the wheel can be spun as long as desired or until the foot of the operative releases the trip and allows the machine to return. This makes the machine automatic or under the control of the operative, as desired.

A suitable guiding-bracket l is secured to the upper rear end of the plate 0, and to the front of the same are formed suitable guides. A vertical shaft Gr is secured to the upper end of the shaft G. Supported on said shaft and guideway is a suitable frame or housing I, which is adapted to reciprocate up and down the shaft G and guide on the bracket 1. To the forward lower corner of the housing I is secured a lever J, which operates on a pivot or fulcrum c. Projecting downwardly and outwardly on the lower end of lever J is a spinning-roll J, which is rounded at the lower side and has a shoulder-like formation at the top. Extending from the upper end of the lever J back to the upper part of the bracket I are links K, which are pivoted at Z) to the bracket I and at Ct to the upper end of lever J. The connection at b has an eccentric adjustment like the eccentric adjustment of the shaft 7c, (seen in Figs. 4, 10, and 11,) the adjustment being eifected by the setscrew f. Secured to the housing 1 is a cable it, which passes over suitable pulleys o o at-the top and is weighted to counterbalance the housing and carry the same upwardly to keep tension upon the same. This cable is secured at its lower end to the housing by the pin a. To each. side of the housing are cables e, which extend downwardly, and these are secured to bolts controlled by nuts f, which have a connection to the housing for adjusting the tension upon the cables. Between the upper plate 0 and intermediate plate 0 are supported pulleys or sheaves g, around which these cables pass. Secured to the ends of the shaft 11, which passes through the cross-head of the engine, are straight thrustbars 0, which pass through suitable guideways to each side under the pulleys g. To the rear end of these thrust-bars O are secured the lower ends of the cables 6.

The portion of this improved spinning-machine bearing wheel J is designed for use in spinning-wheels irregularly formed, as indicated by dotted lines in Fig. 2, and the operation of the machine is such that when the rolls are returned to their normal position the roll J will be lifted by the weight Q) lifting the housing I.

lVhen the car-wheel is placed in position to be spun and the machine is put in operation, as the housing F is carried forward to carry the male spinning-roll H up to the female spinning-roll L, it will, by forcing the thrust-bars 0, put stress upon the cables 6, which carry down the housings I,.and in so doing, by the action of the links 75 on the lever J, move the spinning-wheel J to place and roll or spin the inwardly-projecting portion, as indicated.

After a wheel is properly spun and the machine is returned to the normal position, as

will be readily seen, the weight n will raise the upper housing 1, moving the spinningroll J out of the way, so that the car-wheel can be easily removed and another inserted.

The-motion here secured is that required to properly adjust and bring down the spinningroll J to secure the best formation of the metal in this position. The central part of the wheel, while it is being spun, is supported on a little idle-roll N, which is a beveled wheel supported on a little bracket N at the top of the housing or frame F.

Having thus described my improved spinning-machine and its various parts, I desire to state that the same can be considerably varied in its details without departing from my invention. For spinning the flanges 011 ordinary car-wheels the upper portion carried by the housings I, along with the shaft G and bracket I, can be entirely removed. In this instance the male spinning-roll II should be full and extend upwardly to correspond with the formation of the female roll L,as indicated by dotted lines in Fig. 6. The roll Jand its connections can be used in connection with rolls L and II, if they are actuated by other means than those indicated, and answer its purpose very well. The little idle-roll N, while it serves a very useful purpose, might be dispensed with.

Other means of guiding the wheel to place could be substituted and used for the idlerolls T T, but these will be found very effective and convenient for the purpose. Other variations will, no doubt, readily suggest themselves to those skilled in the art to which this invention pertains.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-- 1.
