WHEEL-RlNl-FINISHING MACHINE.
SPECIFICATION forming part of Letters Patent No. 767,387, dated August 16, 1904.
Application filed April 11, 1904. Serial No. 202,565. (No model.)
To (LZ/Z whom, it Netty concern.-
Be it known that I, NICHOLAS D. CHARD, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Vheel-Rim-Finishing Machines, of which the following is a specification.
My invention relates to a machine for finishing the periphery of a hand-wheel.
The features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Figure 1 is a front elevation of my device. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged section on line n; Fig. 2. Fig. 4 is an enlarged horizontal section of the adjusting mechanism of the work-shaft at the end of the work-stock. Fig. 5 is an enlarged section on line e o, Fig. 2. Fig. 6 is an enlarged section on line w w, Fig'. 2. Fig. 7 is an enlarged section on line e s, Fig. l. Fig. 8 is a detail top plan view of the circular plate and work-stock-supporting plate.
1 represents the bed of the machine, upon which is erected the tool-stock 2. (See Figs. 1 and 2.)
3 represents journal-bearings in the toolstock, in which is journaled the shaft 4, eX- posed at the opposite end of the bearing and preferably supplied with the two emerywheels 5. (See Fig. 2.)
The intermediate portion of the bearing 3 is cut out to provide space for the drivingwheel 7, fixed to the shaft 4 and driven from any suitable source of power, such as a pulley from a counter-shaft.
8 represents a-bed-plate secured on the bed 1. (See Figs. 1, 6, and 7.) The bed-plate 8 has the longitudinal way 9, extending perpendicular to the shaft 4.
10 represents a second plate, having gibbed relation with the way 9 of plate 3.
11 represents a feed-screw connecting the plates 8 and 10 for traversing plate 10 on the gibbed way of plate 8 and manipulated by the handle (t. The plate 10 is a circular or quasicircular plate and has the way 12.
13 represents a plate having gibbed engagement with the circular way of the plate 10, so as to move in a circular path. The plate 13 is provided with the longitudinal way 14.
15 represents a work-stock or Work-supporting stock having a gibbed relation With the way 14 of the plate 13.
16 represents a cross feed-screw connecting the stock 15 with the plate 13 for traversing the work-stock 15 on the way of the plate 13 and manipulated by handle I). The workstock 15 is provided with a bearing c, in which is mounted the work-shaft 17, upon the front end of which is the chuck and centering device-18 for supporting the hand-Wheel 19, which is to be finished.
In order to traverse the plate 13 in its circular path upon plate 10, I provide the following devices, (see Fig. 6:) There is a space formed between the top surface of the plate 8 and a projected end 2O of the plate 10. The extension of the plate 10 is provided with a circular orifice at a point opposite the centers upon which the plate 13 turns.
21 represents a worm-wheel the hub of which, 22, is inserted in this circular orifice of plate 10.
23 24 represent bolts securing the wormwheel 22 to the plate 13, and 25 represents the central bolt through the center of the wormwheel 21 and through the center of which the plate 13 turns.
25 is the center for the concentric way 12 of plate 10.
26 represents a worm feed-shaft (see Figs 1, 6, and 8) having the worm l engaging the worm-wheel 21.
27 represents the handle for turning shaft 26.
It is obvious that by operating the handle a the plate 10 and superimposed parts may be bodily traversed in the direction perpendicular to the shaft 4, that by turning the handle 27 the plate 13, carrying the work-stock 15, may be moved in the circular path around the center 25, also that by turning the handwheel 7) the tail-stock may be traversed on the circularlyltraveling plate 13 in whatever position the latter is adjusted. ln order to rotate the shaft 17, the bearing c is preferably provided with the boxing 31, (see Fig. 5,) in which boxing' is located the worm-wheel 32, the opposite ends of which abut ag'ainst the inner surfaces of' the boxing', so as to form a journal holding' the worm-wheel 32 against longitudinal movement. Shaft 17 is splined or keyed to worm-wheel 32, so as to drive said shaft, but to permit of the longitudinal movement of said shaft. In order to drive the worm-wheel 39., I provide a worin-shaft 33, (see Fig. 4,) having' a worm portion 3&1 eX- tcnded into the boxing 31 and engaging' the worm-wheel 32. The shaft 33 is journaled in a portion of the bearing' c, and this shaft is rotated by any suitable source of power.
ln orderto adjust the work-shaft 17 longitudinally, 1 provide an end bearing-block 35, through which the shaft 27 projects.
36 37 represent collars on shaft 17, placed on opposite sides of the bearing-block 35.
38 represents a guide-pin projecting from the bearing-block 35 into a recess into the bearing o.
39 represents an ad justing-screw journaled in the bearing'eblocli 35 and having' screwthreaded engagement with the bearingc.
40 represents a handle for operating the shaft 39.
ln operation the hand-wheel to be finished is attached to the work-shaft 17, as shown in Fig. 1, and the shaft 17 is so adjusted that thehand-wheel 19, or the periphery thereof, is in line with the periphery of the emery-wheel 5. The handle t is then operated to bring the periphery7 of the hand.-whe`el 19 in con tact with the periphery of the eInery-wheel 5. The hand-wheel 27 is then operated to impart a circular travel to the tail-stoel; 15. Itis obvious that the motion subjects all the portions of the periphery ofthe hand-wheel to the action of the emery-wheel. By turning' the handle t the center 25 of the plate 13is adjusted to or from the periphery of' wheel 5, so providing' the finishing' of hand-wheels of different diameter. By turning the handle the shaft 17 is moved to and from the center 25 of plate 13, so changing the radius on which the work-stock 15 turns and so providing for different curvatures or different diameters of the rims of the handwheels to be finished.
The outside emery-wheel 5 (see Figs. 1 and 2) is for convenience in other grinding, it being possible to mount an ordinary chuck in the way 41, (see Fig. 7 projecting from the tail-stock 15.
Having' described Iny invention, I claim 1. In amachine of the-class described, a bed, l
a tool-stock thereon, a tool-shaft in the toolstock, means for rotating the said shaft, the said bed being' formed with a way perpendicular to the tool-shaft, a plate having' a g'ibbed relation to said way, the said plate being' formed with a circular way, a second plate provided with a way, said second plate having' gibbed relation with thel circular way of the first plate, the second plate being' fulcrumed to the first plate in the line of' the tool, a work-stock having a g'ibbed relation with the way of the second plate, a work-shaft in the work-stock, means for rotating the same, a cross feed-screw for traversing' the first plate relative to the bed, a worm-shaft and worm-wheel connecting' the first plate to the second plate, for traversing the second plate on the said circular way, and a cross feedscrew between the second plate and the woodstock, substantially as described.
2. lnamachine of the class described, abcd, a tool-stocl formed with a bearing, a toolshaft therein, means for rotating said shaft, the bed being` formed with a way perpendicular to said tool-shaft, a plate havinga gibbed connection to said bedway, the said plate being' formed with a circular way around the tool of the tool-shaft, a cross feedwscrew between said plate and said bedway, a second plate fulcrumed to the first plate and g'ibbed to said circular way, a worin-wheel fixed to the fulcrumed portion of the second plate, a worm-shaft journaled in the first plate engaging said worm-wheel, the said second plate being formed with a straight way, a workstoclr g'ibbed to the way of said second plate, said work-stock having' a bearing formed perpendicular to the way of the second plate, a work-shaft in the bearing, means for rotating the same, means for longitudinally adjusting 'the worl -shaft in its bearings, and a cross feed-screw between the way of the second plate and said work-stock, substantially as described.
ln testimony whereof I have hereunto set my hand.
