TO ALL WI-IOM ITVMAY CONCERN:

Be it known that I, 'JOHN F. CHAMBERS, of Calistoga, county of Napa, State of California, have invented an Improved Shingle-Machine; and I do` hereby declare the following description and accompanying drawings are sufficient to enable any person-skilled in the art or vscience to which it most nearly apport-eins to make and use my saidinvention or improvement without, further invention er experiment. v

The object of' my invention is to provide an improved machine for riving and shaving shingles, which consists of a river, upon which the bolts .of the proper length are clamped, and then split out. From this they are 'taken and placed on a roughenedtahle, and aroller is made to pass over them, so as to hold thein firmly down,

o ne end of the tahle rising-at the same time, lse that the end of the shingle'is rmly clamped and held by adcg,

' while the knife, passing directly behind the roller, shaves one side. One edge is jointed at the same time, after which the roller moves back, thetable is depressed, and the shingle freed, when it Amay heturned over and the other side, shaved and the other` edge jointed. By a peculiarmechanism, one end of the table rises at each forward motion of the knife, so as'te clamp the shingle, while the other eudrises, at every alternate motion, and thus gives the shingle the requisite taper, l

'To more fully explain my invention, reference is had to accompanying drawings, forming apart of this specification, of which- Figure 1, sheet 1, is'a plan.

Figure 2, sheet 1', is a side elevation, showing the river.

Figure 3, sheet 2, is a side elevation, showing the shaver.

Figure 4, sheet 2,'is aside sectional elevation, showing` the' mechanism for raising and depressing the table.

Similar letters of reference in each of the figures indicate like parts;

The river consists of a framework, A A, betweenthe sides of which the carriageB travels. This carriage is actuated and fed forward by arack, C, and pinion,D. The dog E is supported and vibrates upon an upright standard, .in frontof which the holt is placed, when theA hinged Ystandard is-raised 'under the end of the dog E, thus pressing the toothed end into .the end ofthe bolt, and holding it lirinly while being cut, Two upright posts,'G G, serve as guides, betweenwhieh the rivin'g-knife H and its sliding frameItravel, reciprocating motion` being given by means Aof the crank's'JJ and the connecting-redsor pitnoen K K. Av bar, "i, is pivoted 'toene of the guides G, so that, asthe frame I rises and falls, it carries a hloek, M,n which moves L back and forward. A pawl, N, is attached' to the lower end of L,and vibrates with it. The pawl slides back and forward on aprojection on the springO, so that, when this spring is up, the pawl is kept out of oontact'with .the ratchet I?, and do es not Afeed the carriage forward, bntwhen a belt has heen placed on the c arriavge, the spring O ispressed down and detained by a notch in the pin It, thas allowing the pawl and ratchet-,to act until the bolt is all split,when the pin S on 'the carriage releases the spring O, by'pressing the block T .to one side, so that the carriageisfed forward no farther, and can he run back at pleasure for anotherbolt, after the split bolt has beenremoved from the carringe.l As fast as the shingles aresplit they fall to the hack ofthe river, from whence they maybe taken and placed on the' roughened surface of the table U.' This table is kept down by a stiff spring, V,and rests .upon two shafts. The shaft a is eccentric, and is operated by-the knee-lever W,'so that, at each forward motion of the knife, the motion of the shaft elifts the end of the table, thus bringingitnearer the clamp or dog, b, sothat the end of a shingle would berinly held in place. The other supporting-shaft, c, is made flat, and is operated 'by the pawl d, and ratchet and the wheel'f, and pinion-g,so that, at each motion, it is turned one-fourth around, thns presenting at onellno'tion itsvedge and atthe next its sideiand alternately raising and lowering'lthat en d of thetable, so that, after shaving one side of a shingle, it may be turned over, and by the rising of the table it will be tapered, as desired. A sliding frame, h, carries the'shaving-knife 1,' and the jointer c, and is operated by the crank m and p itman n. The driving-pulley@ runs loosely on the crank-shaft, andwhen it is desired to Vthrow the .shavingknife forward, it is done by means of a clntch, i, operated by Ithe lever t and treadle u.

When shaving a shingle,l it is placed upon the table U, and the foot pressed on the treadle u, thus throwing the clutch against the wheel. hisV moves the sliding fraaie 7L lwith the knife z' and the roller w forward. The

back end ofl the table being raised, by the knee-leverW acting on the eccentric-shaft a, the shingle is held firmly against the clog b, while the roller 'w presses it down upon the table U, and corrects any winding or warpingof the shingle, and so allows the knife to shave one slide smoothly4 i The fronte is then carried hack land the shinigle released, when,v by removing the footfroml it, time will be given to turn the shingle over, after which the knife inay agziin be thrown forward end beck to its stopping-place by one pressure of the foot. Y When the fname t moves huelga projecting arm, x, comes in contact with.thecurved'ends'of the pawl (Lend moves it back, sc for as to partially revolve the ratchet e,- This turns the shaft c up edgewise, so that by the next movement of the i knife the shingles will have the requisite taper.

Two sets ethninh-screws, z z z z@ Servelto reise and lower the table, sov as'to varythe -thicltnese of the shingle.

The river is intended to Werl( muclrfas'ter' than the shaver, so that in a. short'time a suicient number or" shingles may be split to last the shaver the whole dey, or-one'slmver may be plecd on each side ofthe river. A

The machine may he Worked by. hand, horse', or stenmfpower, but is intended to he portable und work by horse-power.

Having described myvinvention, what I claim7 is- The combination and arrangement of thedog In, movable table U, eccentric-shaft a, end` levers W, for clamping and holding the shingle while itis beingzshavd; and in combination with the parts `nbovef claimed, claim the sliding;r frame t and -lnii'e for shaving the shingle.

I also claim the combination and arrnngcinent of the Het shaftfe, pinion g, wheelfrrntehet e, and pawl d, to alternately raise and lower the end of the table U,'to shave the shingles tapering.

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