Letters .Patent No. 93,148, lated July 27, 1862i.

The Schedule referred to iu these Letters Patent and making part of the same.l

To all whom it may concern Be yit known that I, G. F. WHITE, of Aurora, in the county of Marion, and State of Oregon, have invented a new and useful' Machine for Making Shingles; and Il do hereby declare tllat the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this speciication, in which- Figure 1 is a plan or top view'of my machine, with a portion of the platform removed, toshow parts that would otherwise be hidden.

Figures 2 and 3 are elevations, each on that side of the plan, g. l, to which it is contiguous.

The otherligures exhibit parts in detail, and will be more particularly referred to hereafter.

In all the figures, like parts are indicated by the same letters of reference.

The nature of my invention consists in so arranging the parts ot' the apparatus, to be hereinafter described, as that the operation of splitting the shingles from the block or bolt may be immediately followed by that -of gauging them to a proper width, and smoothing theirsurtaces, while giving these, at the same time,

the proper angle of convergence, and preserving uniformity of 'thicknessin all the shingles. A A A are' the sills, posts, and girders constitutin `the frame of my machine.

B is the main driving-shaft, furnished with fast and loose pulleys, B' B",by which its motion may be derivedvfrom any power, or it may be allowed to rest, and giving motion, by ixed pulleys and belts, to the other parts of the machine.

C is a vertical shaft, having its step in the lower part of the frame A, and its upper end supported in a'bearing xed in the frame of the bolt-holder, (to be hereafter referred to.) It is provided with a pulley, a, and is driven by a belt from themaiu driving-shaft.

' Securely fixed at the upper end of the shaft C, and revolving with it, is the river or splitter, composed of a wooden or metallic rim, D, (see Figures l, 2, 4, 5,) which holds, between itself and the hub, the rivingknives b l).

These-inlay be two or more in number, and are secured with their edges radial to the rim. Their upper and'under surfaces forma spiral plate around the axis, like a post-anger blade, each plate terminating radially immediately under the edge of the knife attached to the next plate, so that the space of the thickness required for a shingle is open between each knife-edge and the plate of its neighbor.

That portion of the plate which is under a knifeedge is free from Contact with the rim and hub for a portion of the distance around from its lower edge to its knife, as secu at b b', gs. 4 and 5, which are a direct and anoblique view ofthe under side ofthe river, to allow it a slight degree of flexibility, which is governed and regulated by the pressure of the spring c, attached to the under side ofthe rim, and bearing against the under side of the free end of the plate, as shown.

Boxes, al d, are formed in the construction of the frame, to serve as bolt-holders, and the river is so placed on the shaft O as that its knives shall come in contact with and split from the bottom of the bolts or blocks placed in the boxes 4Z.

E E are the shafts of the pairs of saws e e', driven. in opposite directions by, belts from the main shaft B,

as shown by arrows in iig. 2.

As each of these pairs of saws is a duplicate of the other inv construction and operation, it is only necessary to describe one and its adjunets.

The bearings of the shaft E are so placed that the edges of the saws project a slight distance above th surface of the bed or platform A', partially covering :the top of the frame A, as Aseen in tig. 1,"where the dotted lines indicate that portion which has been removed to make the drawing clear.

The saws are each covered with a shield or guard, to protect the attendant from injury.

The saw e is xed to a collar sliding by a groove and spline on the shaft E, so as to revolve with it, and

is moved toward or from the saw c, which rotates in a constant plane by the shipper j, of the kind commonly used, and plainly shown in the drawing.

A rest, g, seen detached in Figures 9 and l0, slides on the guide-bars h h, between thesaws, and ina direction at right angles with their axis, against which the shingles are laid, and pushed between the saws, to be cut by them tothe required width. i

The rest g is drawn back for another shingle by means of a cord attached to the barrel t', containinga spring, t', shown in blue lines in iig. 9, which last is kept in tension bythe commony device of a ratchet and pawl, lt.

F is a -vertical shaft, driven by a belt from the main 4 shaft G, and carryinga planer, for smoothing the shingles, and giving them the necessary taper.

This planer is composed of two plates, G G', irmly fixed one above the other on'the shaft F, so as to turn with it, with a sufficient distance between them to allow for adjustment of the plane-bits or knives.

Figure 6 is ay separate view of'the top face of the upper plate Gand the bottom face of the lower plate G'; Figure f1' isa view of the contiguo-us faces of the same plates;land

Figure 8 is an edge View and partial section of the same.` y

The upper plate G, it will be secu, is slightly conical on its under surface, andl the plane-bits or lgnives l l are adjustable, so that their -edges may be-either .parallel with theradii of the surface or describe a more acute or obtuse cone.

Rollers In mare set` in the under face of the plate Gr, in close proximity to the edges of the knives, and are also adjustable, to be parallel wit-l1 them.

The degree of inclination of the knives of the plate G to the plane of rotation determines the taper of the shingle.

The knives and rollers of the lower plate Gr' are similar in construction and arrangement to those'of plate G, but'arc so set as to revolve inthe same plane with the upper surface of thc platform A.

Opposite to each pair of saws, and on each side of the planer, is a feeder, revolving horizontally on the vertical shaft H, and driven by a belt from the main driving-shaft B.

This feeder is composed of two plates, I K, one of which, I, is Iixed on the shaft, with itsupper surface flush with the platform A', and the other, K, is loose on the hub of the plate I, so as to be free to assume a position out of a horizontal plane. It is made to turn with the shaft, however, by means of thevpins u An, projecting upward from the plate I, through hole-s in the vplate K The upward motion of plate K is limited by the heads of the pins n n.

L L are two friction-rollers, attached to stems, which are free to slide vertically in the sockets o o, through which they pass, until they come in contactiwithaml are held down by the springs M M.

These rollers impose on the top ofthe plate K, near the edge which is next to the'planer Gr G', and by the springs M, grip and Vhold the shingle firmly by one end between the plates I K, while it -is'being planed.

A bar, N, which may have elasticity to act as a sprii ",when desirable, is attached by one end to a convenient point on the frame A, and has its other end projecting into the space between theplatesl and li, for th'e double 'purpose of keeping the space open for the ready introduction of ashingle from the saws, and for throwing ontthe shingle when it has been planed, and is leftiree by bein g relieved from the pressure on the plateK.

It will be seen from the drawings that the speed of the planer is much greater than that of the feeder, so that while the shingle is being carried from the saws around to t-he point where it is released, the planebits perform their office in tapering and smoothing etfectually. l

The operation of my machine is asfollows, viz:

lhe blades of the river having been put in proper condition, the saw e', set upon the shaft E by the ship perf, and secured at the proper distance from the saw c. andthe knives and the rollers of the planer properly adjusted, bolts or blocks are put into the boxes d d, and the machine pnt in motion.

As fast as the shingles are split, they fall on the Vplatform A', and are conveyed to the rest g, placed in plates b', and springs c, together with the adjustable gauge-saws c e' and the selilretracting rest g, all arranged substantially described, and operating as and for the purpose set forth.

.2. ',lhe feeder, composed of the plates I K, rollers' L, springs M, or their equivalent, and bai-N, arranged and' operating substantiallyas described.

. The rotating planer G G', with its adjustable knives Z and rollers` m., in combination with the feeder I K L M N, as hereinbeforc specified, for the purpose s et forth.

4. rlhe combination of the width-gauging devices c e (1, with the feeder above mentioned,substantially as set forth, and for the purpose described.
