Letters Patent No. 86,006, dated J millar/ 1; 19, 1869.v
IMPROVEMENT IN HUBBQRING MACHINE.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concerny Be it known that I, EW. DEXTER, of Randolph, in the county of Gattaraugus, and State of New York, have invented a new and improved Box-Setter for Wheel- Hubs; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, formingpart of this specification, in Which- Figure lis a central vertical section of my improved box-setter,when applied on a hub for operation.
Figure 2 is a bottom view ofthe plate A.,
AFigure 3 is a bottom view of the upper plate B.
Figure 4 is a detail section of the box t', through the line y y, iig. 3.
Similar letters of reference indicate corresponding parts. The nature of this invention relates to the boring out of a conical seat in wagon-hubs, in which to receive or set the axle-box, and combines a number of devices, which conduce to provide a more convenient and desirable apparatus for the purpose than has heretofore .been known or used.
It consists ofthe various improved features or devices set forth in the following.
In the drawingsj A and B are circular plates of cast-metal, each being formed with a spiral scroll, D, as shown, for actuating the clampplates, C, to or from the centre, the said clamp-plates being formed with teeth to fit in said scrolls, in thcmanner of a scroll-chuck.'
The clamp-plates are also formed with clamp-proj ections, a, having dovetailed recesses, as shown, for receiving and holding blocks of tough wood, b.
The object of this device is to enable a firmer hold to be had upon 'the hub when the same is banded, as shown in fig. l, for woodagainst vmetal is less liable to slip than metal against metal.
' When the hub is not banded, the wood blocks may be dispensed with, for the clamp-projections willhold on the wood with all the firmness required.
The lateral edges of the clamp-plates are suitably grooved, to be retained in the slots of the guide-plates, E E,which are formed with radial slots, in which the lsaid clamp-plates move.
.The guide-plates are held in Working-connection with their respective scroll-plates A and B, by means of the collar-flanges G, affixed by screws or otherwise to the 'annular projections o from the guide'- plates, which latter fit easily within central circular openings in the scroll-plates, as shown, and thus enable the latter to be moved freely on 'the guide-plates, to actuate the clamp-plates to or from'the centre.
The guide-plates also have central circular openings, corresponding in size to the similar openings of the scroll-plates, for apurpose which will be obvious in the ensuing. description.
The guide-plates, scroll-plates, and clamp-plates,
thus constructed and combined, are applied to the ends ot' the hub, as'sbown in fig. 1, and the clampprojections are tightened upon the hub by means of arod, as shown in red, in iig. 2, inserted between the studs d, cast on the exterior side of the" scrol1-plates,which serve to turn the scroll-plates as desired.
H is the boring-rod, having a crank-handle, H, and has a screw-thread cut in its lower half, as shown.
e is the cutting-tool, projecting therefrom, to cut out the conical box-seat in the hub I.
This rod is of the usual construction, nothing being claimed therefor.
In order that the box-seat shall be bored or reamed out with a conical form,suitable for receiving the axlebox, the rod must be made to inclin from the-central axis of the hub, and must have a'gyratory revolution. This is permitted by the devices now to be described. J' is a circular plate, fitting easily within a corresponding opening in the guide-plate of the scroll-plate B.
It rests on a shoulder, h, cast within the circular part, c, of the guide-plate E.
The other guide-plate is formed with a similar shoulder, h',which latter is, however, Vfor another purpose, as will be shown.
vThe plate J is formed with a rectangular openingor slot, K, in which the box i (having a square hole somewhat larger than the cross-section of the lrod H) slides.
This box is formed with a grooveon one side, and a bevelled edge on the other, which bevelled edge iits against and upon one edge of the slot, which edge is bevellcdLto fit the bevel on the box, as shown at fig. 4, in Which figurelk is the groove,
m is the bevelled edge of the box, and
n, the correspondingly-bevelled edge of the slot in the plate J.
lis a projection, cast on the box, through which a clamp-screw, j, passes, and passes through a narrow slot, q, in the plate, parallelto the larger slot, K.'
A nut, o, under the plate J, tits Von the said screw j, and is kept from turning lby a feather, p, cast on the plate J, as shown.
By this latter device, the screw j can be turned without turning the nut with it.
The bevelled edges tm and n serve to hold the box in its allotted place, at any point of the slot K, when the rod H, which passes through this box, is set at the desired incline.
This feature is of considerable importance, as it furnishes thc means of easily adjusting Athe rod to' the proper inclination, by loosening the screw' j, and moving the box, and clamping the box afterward by a single turn of the said screw, which brings the aforesaid bevelled edges m n to impinge against each other tightly, thus jamming the box firmly in theslot,
The rod H is permitted to operate with the aforesaid gyratory revolution, by means of the circular plate L tting easily within the central circular opening of the guide-plate of the scroll-plate A, and a ring of rubber or other elastic packing, fr,- for the nut M, through Which the rod H passes, is attached to the said plate L, and moves with it, so that, as the rod His gyrated, the plate L will obey the same motion, and compress the packing-ring lr at each successive point of the same.
This packing-ring is interposed between the collar G and the plate L, as shown. Y
The degree of compression of the packing-ring, and the relative inclination of the plate J, are somewhat exaggerated in the drawing, Ythe better to illustrate the principle of -its operation, but, in practice, a slight compression of thepackiug-ring would permit all the inclinationthat is usually required of the rod H.
The nut M may be of any suitable construction,lbut I have provided an open nut, for convenience, which consists in the two parts, M M, each containing half of the thread, and pivoted to a stud, P, cast on or tapped into the plate L. l Y
The two parts of the nut are brought together by a lever, 0, having an enlarged p'art, N,which is slotted in its proximate face, so that studs or projections from the proximate parts of thennt M M will traverse freely in the said slots.
The slots are curved, and so arranged in the part, N, that, when the lever is inoved in `one direction, the nut will be opened, and closed When'moved in the reverse direction.
The lever is pivoted to' the plate L by a stud, t, and the proximate faces of the parts M M are cut' out at this point, to enclose the stud t when the nut is closed.
Q is a tapering shoulder-projection, cast on the collar, G, to. hold the lever in place, after the uut is closed.
An advantageous feature of my invention obtains in the fact that it is self-centring; 4that is to say, the clamp-plates are so arranged ou the scrolls, that they are equidistant from the centre of the plates A and B, and will maintain their relative positions, as they are moved in or-out by the scrolls.
By this condition, when the plates lare clamped on the hub, the axial centre of the latter will coincide with a line connecting the centres of the scroll-plates,
thus obtainin g the true centre of the hub, as it is bored,
without particularly adjusting the 'machine with reference to such centring.
I claim asnew, and desire to secure by Letters Patent- 1. The combination of the plate L and packingring r with the collar-ange G, annular projections c of theA
