Be it known that I, JOSIAII P. N. DAVIS, of Point Arena, county of Mendocino, State of California, 4have invented a new and improved Shingle-'lilachne g" and I do hereby declare the following description en d accompanying drawings are suiiicient to'enable any person skilled inthe art or science to which it most nearly appertains to make and use my said invention or improvement Without further invention or experiment.

My invention relates to that class known as shingle-machines, and has for its object the construction of'- a machine which shall .he portable,and which may be operated either-hy handor other motive-power. v

This machine rives the blocks which are fed to it, joints and shaves the shingles, and finally piles them ready for binding or tying. i

To accomplish this, the blocks, of the p`ropcr length, being placed on the carriage on one end, it is moved forward by a cam on the shaft, operating in a rackon the carriage. This cam moves the carriage and block forward just the thickness of one shingle, when the riving and jointing-knife splits it off, and trims theedge at the same time, so that the shingles in one bunch will all be of the same width. After being split olf, the shingle isseized by two clamps, which draw it up between the shaving-knives, these knives being drawn closer together as the shingle passes up, soV as to taper and give it the desired sha-pe. After leaving the knives, the shingle is released from the'clamps, and at the same moment. pushed by a'lever into a trough. The first shingle will pass down the incline, point-irst, and be deposited in the receiving-box, with the thick end atene side and the thin end in the centre. By means of a cam, a diaphragm or partitionin the trough is then lowered so that the next shingle will pass down 'another incline, above the first, and be turned over during its passage, so that its thick endrwill be laid against the opposite side of the box from the rst one', and its thin end toward the centre, and so on, alternately, 'till the boxv is full, when it -.vill be moved along for binding, and another box brought into its place, to receive shingles. By appropriate mechanism, the shavings are all carried away from themac'hine as fast as made.

To more fully explain my invention, reference is had to' the accompanying drawings, forming a. part lof this p speciiication, of which- Y Figure 1, sheet 1, is a side sectional elevation, taken through av Figure 2, sheet 1, a side sectional elevation through y y.

Figure 3, sheet 2, is a plan. Figures .4, 5, and 6, sheet 2, are details of parts of thc machine. Similar letters of referenceindicate like parts.

A is the frame of the machine. At' the proper height are placed'supports, uponwhich the carriage travels. This carriage is divided into the sections B B', so that as one sectionpasses` through, another may be introduced. The rods c c steady the blocks, and keep them in position, and may be set for any desired width'of shingle, or to any size of blocks. D is a rack, attached to one side of the carriage', intov the teeth of which the cam E (o n the`shaft) reaches, so that the carriage with the blocks is fed along, theteeth being of such size that it will be fed just the thickness required for the base of a shingle. A pin, F, operated by a spring, and by the slide which supports the riving-knife, is pressed forward against each shingle as vit is split off, thus steadying it till the clamps take hold of it. G is the'riving-lmifc, having its sides bent at right angles, soas to joint the edges at the same time that the shingle -issplit off. The clamps II I-Idcscend at the same time with the knife G', being situated above-and forward of it, and attached to the same sliding frame. These clamps, (shown clearly in fig. 5, sheet 2,) pass freely down on each side the shingle, butqvhcu drawn up again, are forced into thc substance of the shingle by the resistance, so that they draw it up between the shaving-knives I I. These knives are supported by the axes d a,'being elongated and curvcdlfrom the cdgc to the tops, which are near togeth'er. The tops or backs of these knives are brought near enough together to be acted apen hy the enlargement Z of the curved sliding rod c, this enlargement Vbeing proportioned, so as gradnaly to close `the edges ofthe knives I I, by opening their backs, thus tapering or thinningthe shingle towards its edge. As the shingle reaches the top, and after leavingthe knives, astationary rod, K, 4or similar device, comes in contact ,with the clamps'H H, and disengages them from'the shingle, which is at the same time thrown into the inclined delivery-trough L, by

' alever, M, operated by thel shaft N, to which itfis fastened. The delivery-trough is divided into an upper and lower passage, 0 and P, so that one shingle is received into the passage P, and passes directly into'the receivingtrough R, with its point in the centre and its head at one side. The next shingle is delivered into the passage O, in 'this manner,,viz: A cam, S, is'situated on the main driving-shaft, and, as it turns, raises and lowers the arm T, which in turn4 moves -the lever U. This raises and lowers the pin rZ, and, by this means, the diaphragm er4 partition g, which the pin d operates, and which is hinged for that purpose at h. When lowered, the shingle passes down above it, the passage being so formed that the point ofthe shingle passes over the bar z', and the weight of the butt end revolves it, (orlby other equivalent device,) thnsdepositing it in the receiving-box with its point in the centre. This receiving-box is moved along, when full, bythe followingdc'vice: Below the carriages B B', are the inclined planes m m. A lever, n., (shown in fig. 4, sheet A2,) has oneoits ends operated by theseinelined planes. Another lever, 7', iig. 2, is placed at right angles with ithe lever n, each being suspended in the centre, and attached to each other. At the end of the lever r is placed the latch t, so arranged as to operate the pins u in the bottom of the box R. As the carriage moves along, the inclined plane 'm gradually deprcsses the levers and the latch t, its straight edge being in contact with the pin u, till it is depressed below the pin. At thcsamc instant the lever 1t is released and falls between the inclined planes m, thus allowing the'spring z to force the' latch up again on the other side of thepin u., the angle being sufficient to force the box R along, so as to present a new space to be filled, while the lever V may be used to 'press the first paclcagefor binding. u

The shavings from the front of the shingle fall into the discharge-trough W, while those from behind are caught and thrown into thesame spout by the vsliding-plate X, which moves on an inclined guide, and is operated by thcarm Y, attached to the shaft N or the block N', as shown.

When the machine is to be operated, the blocks, sawn to the properV length, are placed endwise upon the carriage B, the rods c c being moved so este accommodate any width of timber which is to be used. The main shaft S is then revolved in the direction shown by the arrows, turning with it the cam S. B v means of the gear-wheels .I J, the shaft Q, with its crank q,`is revolved, and through the connecting-rod F and crank l, the. rockshaft N receives motion, which is communicated to the riving-knife and clamps by the arm Z. As the knifeN 1 G falls, it splits off a block of the proper thickness, which is immediately seized -by the clamps or jawsH H,

and drawn up between the knives I I. '.lhese knives shave it, as before described, and as it leaves them, thc red c disengages it frcmthc clamps, and the lever M pushes it into the discharge-trough L, down which it passes into the receiving-box R, and is laid ready for bindingt 'i The'partitions in the 1eceivingbox arc movable, sc as toaccomniodate any width of shingles which may comefrom the machine, it being intended that all in any one bunch shall be of the same width.

As shaved shingles can only be made from clear, straight'timber, which can generally be found only in.

small quantities at any one place, it is impossible to sct up a local mill, and this machine has been constructed to obviate the diiiculties'hitherte encountered, it being portable, and may be operated by twomen, or horsepower may be used.

Havingthus described my invention, what I claim, and 'desire to secure by Letters Patent, is-

1. The combination and arrangement .of the clamps II I'I, for holding the shingle, the curved pivoted knives I I, and the` wedge Z1, for graduating the distance between the edges of the same for tapering the shingles, substantially as described. I

2. 'lhc combination and arrangement of the rod K and lever M, for releasing and delivering the finished shingles,-substantiallyl as described.

The double delivery-trough L, divided by the vibrating-diaphragm g, in combination with the cam S, arms T and U, and pin cl, for operating the sanne, substantially as described.

4. The bar or rod z', in combination with the vibrating-diaphragm g, for reversing every alternate shingle on its way to the packing-box, substantially as described.

5. The sliding packing-box, having movable partitions, in combination with the iuclines m m, levers n and 1', latch t, and spring s, for operatingthe same, substantially as described.

In witness whereof, I have hereunto set my hand and seal.
