Letters Patent No. 96,818, dated November 16, 1869.
IMPROVEMENT IN MACHINE FOR CUTTING FELLOES.
'l'he Schedule referred to in these Letters Patent and making part of the same.
Be it known that we, WILLIAM A. LEWIS and GEORGE W'. BUTLER, of Joliet, in \Vil1 county, and State of Illinois, have invented a new and improved Machinefor Cutting out Wagon-Felloes; and we do hereby declare the following to be a full,k clear, and exact desclipt-iou of the same, reference being had to the annexed drawings, makinga part of this specification, in which.-
Figure l is a perspective View;
Figure 42, a plane view on the top;
Figure 3, a rear elevation ;v
Figure 4, a perspective view of a single cutting-bit; and
Figure 5, a view ou the bottom of said bit to show the curveof its outer side.
Thismachiue may be constructed wholly or in part of metal, as desired, and is operated and arranged as we shall now proceed to explain, relying as much on the representations in the drawings as in the description, to convey our ideas.
t is a frame, upon which rests an adjustable table in two separate parts, b and e, supported by the main frame a.
These parts may be moved' to or from each other by means of the counter screw j, figs 2 and 3, which is boxed in the counter frame a, at each end, and is attached t0 the two part-s of' the table?) and c, by means ofthe nut-boxes n and o, tig. 3.
It will be readily observed that by turning said screweach partof the table will be moved either to or from the other, according to the direction the screw is'turued, which is for the purpose of adjusting the dogs e and lto any distancevapart, to accommodate the machineto any length of the pieceto be cut.
The set-screws s and slots prevent the tables from being moved too far either way.
IThe adjustable table rests upon the frame t, which may be moved horizontally, by means of the screw d, operating in the nut p, attached to said frame, as shown in iig. 2.
.This is for the purpose of accommodating the dogs e and l to any circle to which the cutting-bits c may beset to cut.
The dog e is arranged 'to slide laterally, of the level' t', to receive the block to be cut between them, as it rests upon the rests 8 and 9, shown in iig. 1.
fis au adjustable gauge, to regulate the distance the block is to be shoved into the machine between the dogs, so that the cut may be uniform each time.
This gauge f is operated by the levers g and h, attached to the dog e, as shown iu, fig. 2, and is regulated by means of the slide q and set-screw r.
z is an upright shaft, standing ina step, 4,'on the elliptical spring l, upon which itis allowed to move pexpendicularly, by means of the levers 2 and 3, the lever 2 having a forked end. which engages with said by means shaft, as shown in fig. 3, to bring it down, which is done by pressing down with the foot on the end-.of the lever 3, iig. 1.
The cutter-head m is attached tosaid shaft, as shown in ligs. 1 and 3, and revolves by means of a belt on the pulley 5.
A double row of concentric cutting-bits e are attached to said cutter-head, and are arranged in radial slots, as shown in figs. 1 and 2, by means of which they may be set to cut any desired circle, and may also be set at any distance apart, to cut any width of afelloe.
'lhe cutting-bits are constructed in about the shape shown in figs. 4aud'5.
Fig. 4 is a perspcctiveview of, a single bit, which is constructed with a projectiouon the upper part, which lits into a correspoluling groove on the under side of the cutter-head, shown at 6, figs. 1 and 3, the object of which is to around while at work.
A cross-section of the cutting-bit is shown ati," i
prevent the bit from turning IVe are aware that machines have been before used, iu` looks `quite sin'lilar, for the same purpose, but heilig objectionable, as compared with this, in several respects, the main ones of which are thata separate machine has had to-be used for every different circle desired to be cut, while in this machine any circle practicable vmay be cut, simply by adjusting the cutting-bits to suit the circle.
Also, the cutting-bits are bl'ought down to their work, instead of the work being brought up to the bits, which is a great improvement, as can be readily seen, as the table is-left perfectly solid and stationary, a desirable feature when we contemplate that the variation of one-sixteenth of an inch will spoil the work for ielloes, which isinvariably thc case when the table is moved up and down.
Claims.
fe claim- 1. The combination and arrangement of the shaft 2,.
o', and adjustable table baud c, as and for the purposes set forth.
