lIIVI,PROVEli/.IIIEINTIP IN SHING-LE-MACHINES.

The Schedule referred to in these Letters'Patent and making part of .the same.

indicated by the line :t :t in tigs. 2 and 4, which latter figure is a plan with the feed-boxes and upper covers removed Figure 5 is an inverted plan of the'revolving bed,

which carries the knives; and

Figure 6, a sect-ion through the revolving bed, taken as indicated by the line z z in fig. 4.'

Similar letters of reference indicate colresponding parts.

- My invention consists-ln a rotary shingle-machine, in which the knives are carried by a bed arranged to travel around a vertical axis, and includes various peculiarities of construction and combinations of parts, to provide for varying the angles of cut,and otherwise perfect the operation ot' themachine.

Referring to the' accompanying drawing- A represents a revolving horizontal bed, mounted on a vertical driving-shaft, B, and arranged to rotate within an annular curb, u, carried' by the 'frame C ot the machine. v

D is a cross-tie, secured at its ends to the main frame, and serving to support the upper end of the shaft B, also formed with vertical sides or wings b, that, in conjunction with wings b', on'fast intermedi ate covers E, form opposite sides to feed-boxes li, in which the y,bolt-s required to be worked up into shingles are placed, and through which, onto the revolving bed A below, they are fed or drop.

This bed A, the upper surface of which lies the thickness of a shingle, or more, below the bottom edges of the boxes F,.or lower surfaces of the crosstie D and covers E, carries, on opposite sides of its axis, knives G G', arranged to project obliquely up through it, and preferably shaped to form reverse sweeps ou their cutting-edges, and arched or curved throughout, resembling in their construction the section of acone.

These knives are so set, or the upper surface of the bed A- so formed, that in their action upon the bolts, they alternately cnt at reverse inclinations through the bolts relatively to the length of the latter, which are here, lby the arrangement of the boxes F, shown tooccupy a radial position to the dri ving-shaft.

. To eii'ect this, the upper surface of the bed A may he made shelving in reverse directions in front of the knives, that is, made to dip from the hub toward the periphery in tiont of the one knife, and from the'periphery toward the hub in advance of the other, which gives a reverse inclu-lation4 to the projectionv of the cutting-edges of the knives above the bed surface, so that the one knife makes its deepest cut in an outwardly direction, and whereby the bolts are worked up vas regards the taper ot' the shingles from opposite ends alternately, without any special feed-motion to alternate their angular position, but simply as they drop or are forced through the boxes F.

Clearance openings d d for chips are made through the bed in rear ot the knives.

The shingles as cut pass out from under the knives.

.As it may be desirable to increase or diminish the inclination of the cut, for the purposeiof making shingles of different tapers, the revolving bed A is made up ot' adjustable sections H H', each section being adjustable relatively to the knife it operates iu'A concert with, by screws e e and e' e', to vary the depth or dip of their reverse inclinations on the upper surface of the bed.

The knives G G are also made capable, by means of screws f f and' slots g y', of being set in or out from the lower surfaces oi' the bed.

I do not limitmyseif to one pair of knives, G G', or any particular number of feed-boxes F.

1f desired, the bed A may be arranged on a horizontal shaft, andthe bolts be fed'or pressed up against the vertical bed in horizontal directions, by any suitable means.

What is here claimed, and desired to be secured by Letters Patent, is-

The revolving bed A, constructed of adjustable sections ll l-I, substantially as shown and described.
