SPECIFICATION forming part of Letters Patent No.A 529,661, dated November 20, 1894.

.Application filed November 2. 1892. vSerial No. 450,747.1- (No model.)

To all whom it may concern.;

Be it known that 1, LEvi H. MoNTEoss, a subject of the Queen of Great Britain and Ireland, and a resident of Camden, New Jersey, have invented certain Improvementsin the Manufacture of Shingle Siding and Machinery Therefor, of which the following isa specification.

The object of my invention is to provide a method and means whereby siding strips or clap boards such as are ordinarily used for building purposes may have representations of shingles formed in relief thereon, as set forth, for instance, in my application for patent filed August 25, 1891, Serial No. 403,672. This Object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l, is a side View of a machine constructed for the manufacture of shingle-siding strips in accordance with my invention. Fig. 2, is a view of the opposite side of the machine, with the driving pulleys removed. Fig. 3, is a plan view of the machine. Figs. 4 to 9, inclusive are detached views of parts of the machine;= and Figs. 10, l1 and 12, are

diagrams illustrating a certain feature in the operation of the machine. l

In carrying out my invention the represen tation of the shingles in relief upon theface of the strip is effected by the action of a pair of cutting knives and a circular saw, kthe latter being reciprocated across the face of the strip and the knives being shaped to accord with the desired contour of the recesses to be formed in the face of the strip, one of these knives working at right angles to said face so as to form incisions in the strip, and the other knife Workin g in a direction parallel to the face of the strip, but some distance back of said face'so as to cut out a chip from the space bounded by the incisions formed by the other knife, the knives operating, by preference, in the manner hereinafter set forth so as to follow each other in their action, and form chipsv of different thickness by successive cuts.

In the drawings A represents the xed frame of the machine to suitable bearings a on which eccentrics B and D, 'a spur pinion F,

and a belt wheel or pulley G.

The strap of the eccentric B is connected by an adjustable right and left threaded rod b to aslide B' which is free to move back and .forth in suitable guides b at the top of the fixed frame, said slide B carrying a cutter B2 of the shape desired for the recess to be formed in the face of the strip, the knife in the present instance being inthe form of an inverted V, as shown in Fig. 4.. The cutter B2 is mounted upon a supplementary slide B3 which is adjustable laterally across the face of the slide B so that the lateral position of the knife B2 can be varied as desired.

, The strap of the eccentric D is connected by a rod d to a lever D hung to a depending frame d and connected by a rod d2 to a slide D2 which is guided in suitablevertical ways d2 on the iixed frame and has a transverse guide d4 to which is adapted a second slide D5 carrying the vertical cutter D4 Which is shaped to conform with the cutter B2, as shown in Fig. 5. The spur Wheel F meshes with aV mounted in suitable bearingsfon the frame of the machine, and carries a pair of cams h, a crank disk c', and a combined cam and crank disk m. The cams h act as shown in Fig. 6 upon sliding boxes h which are connected by rods'h2 to a work carrying head J at the outer .end of the machine, the lower rod h2 being k2 so that when a siding, stri p is mounted upon the plates K its inner face, that is to say, the face toward the knife B2 will bearagainst the rounded faces of the lugs lo and its outer face will be acted upon by the lspring plates or fingers k2. The strip also passes between rollers n and the vertical portion of the head J, and mounted on a lug 'a' on the said head is av lever n2, the long arm-of which is acted upon by the spring n2 while its short arm is toothed or roughened and serves to press downward upon the strip and thereby retain the same in proper vertical position upon the head and also to prevent any backward movementofthestrip. (See Fig.8.) Iftransverse reciprocating motion is imparted to the slide bar K, the strip held between the lugs lo' and spring fingers k2 will, on the forward movement of the slide har, be carried along with the same, the lever n2 yielding to permit such movement, but on the hack ward movement of the slide bar K the levern2 will grip and hold the strip, and the lugs k and fingers 7a2 will slide on the same until the direction of movement of the bar K is again reversed, so that intermittent forward feeding movement of the strip is thus effected, and the knives B2 and D4 are caused to act upon different parts of the si rip in succession. Reciprocating movement is imparted to the slide bar K from the crank disk lon the shaft H by means` of devices best shown in Fig. 2. The pin of said crank disk i is connected by a rod '1l' to an arm t2 on a rock shaft L2 which carries a bevel wheel 4, the latter meshing with the bevel pinion t5 on a shaft t6 which carries a crank t7 having a pin 'which is connected by a rod 't8 to the .slide bar.

Whilel prefer the mechanism described for eiecting the feeding of the strip, it will be evident that other known formsof feeding devices could be used without departing from the main features of my invention.

As shown in Figs. l and the belt pulley G has a belt g which drives a pulley g on a shaft g2 carried by the lower ends of a lever M and arm M bot l1 hung to the shaft A and connected by a transverse bar M2 so as to form a swinging frame which will be referred to hereinafter. The shaft g2 has a belt pulley g2 to which is adapted a belt g4 also adapted to a pulley g5 on the spindle rof a circular saw said spindle being adapted to bearings in the upper ends of arms N, N movably hung at their lower ends to the shaft g2.

The rear arm of the lever M is connected by a rod m to a crank pin m2 on the disk m, so that as said disk rotates a rising and falling movement will be imparted to the saw, and the latter will be carried vertically across the face of the strip so as to form a kerf therein. In order to regulate the character and depth of this kerf I employa guide bar P suitably mounted upon the carrying head J, and serving, by contact with one of the bearings of the saw spindle or with a collar on said spindle to limit the approach of the saw toward the strip, so that by varying the shape or angle of this guide bar the kerfs may be made of varying depths.

The saw `is pressed toward the strip-by the action of a spring leg s at the upperiend of an arm S pivoted to the shaft g2, this spring leg acting upon the bearing at the upper end of the arm N which carries the saw spindle, a constant backward pull being exerted upon the armsN N` by a spring N2 which acts upon a bar N3 connecting said arms and is fastened at its rear end to a pin N4 projecting from the lever M. Forward movementisimparted to the upper end of the arm S and its spring leg s at the proper time by means of the cam disk m, said disk acting upon a lever lm3 which is connected by a rod m4 to one arm of a lever 'm5 hung to a suitable stud on the fixed frame, the other arm of said lever havingapinmbearingupontheleverS. Bythis means the saw, during one of its reciprocating movements, sayduringtheupward movement, may be caused to act upon the strip and to cut a kerf therein of a character and depth depending upon the guide bar P, the saw being then withdrawn from action upon the strip and held out of action during the reverse or downward movement.

The object of imparting the iu and out movement to the work carrying head and its feeding devices is to provide for forming the recesses in the face of the strip by cutting from said strip successive chips of different thicknesses. For instancetthe tit-stout of the knives may be eliecled While the table is in its outward position so as to `cnt from the strip a thick chip y as shown in Figs. l0 and 1l, for instance, and the table may then be moved inward slightly so that on the next action of the knives a thin chip 'y' is removed from the base of the recess previously formed, as shown in Fig. l2. I find that by this means aclean-cut and sharply defined recess is formed so that the representations of the shingles will have the desired clean and sharp outlines. It is preferable to give the horizontally acting or incising knife B2 a slight lead over the vertically acting or chip `cutting knife D4, so that the knife B2 will have made its incision, as shown in Fig. 10, before the knife D4 reaches the limit of its upward stroke, and said knife B2 will have been withdrawn slightly by the time the knife D4 is fully elevated so thatthe latter may cross the incisions, as shown in Fig. ll, and thus insure the cutting loose of the chip.

I find it advisable to provide the block B3 which carries the knife B2 with projecting pressers t located adjacent to the knife blade, and projecting slightly `beyond the same so that they will strike the face of the strip and be compressed thereby on the forward movement of the knife and hence by their re-action will press the-strip away `from IIO the knife on the rearward `movement of the i h and thence to the shaft Hso that the strain upon the main frame A isa compression strain between the bearings of the shafts A and H, there being no tensile or stretching strain upon anyy portion of the main frame, such strains being exerted wholly upon and resisted by the rods h2. The use of the rods h2 in the manner described would therefore be of value even if the work carrying head had no movement, and hence I propose to use them in machines having either fixed or movable heads.

Having lthus described my invention, I claim and desire to secure by Letters Pat elli- 1. The combination in a shingle siding machine, of an incising knife and a chip cutting knife working at right angles to each other,a Work carrying head, means for intermittently feeding the strip along said head, and means for causing movement of the head toward the cutting knives between successive feeding movements of the strip, so as to provide for the cutting of successive chips from the same portion of the strip, substantially as specified.

2. The combination in a shingle siding machine, of means for supporting and intermittently feeding the siding strip, with the incising` and chip cutting' knives, thefcircular saw, means for rotating and reciprocating the latter, and a guide bar for limiting the depth of cut of the saw, substantially as specified.

3. The combination in a shingle siding machine, of the xed frame, the carrying head, the reciprocating cutters, the operating shaft therefor, and tension rods extending from the carrying head to a point beyond the bearings for the knife operating shaft, substantially as specified.

4. The combination in a shingle siding machine, of the fixed frame, the reciprocating knives, a shaft for operating the same, the carrying head mounted upon the frame, boxes connected to said carrying head by means of rods, and a shaft having cams for acting upon said boxes so as to impart movement to the head, substantially as specified.

5. The combination in a shingle siding machine, of the main frame, cutting knives guided on said frame in directions at right angles to each other, a shaft having a pair of eccentrics, a rod whereby the strap of one eccentric is connected directly to one knife slide and a pair of rods and an interposed lever whereby the other eccentric is connected to the other knife slide, substantially as specified.

6. The combination in a shingle siding machine, of the fixed frame, means for supporting and intermittently feeding the siding strip, a circular saw, arms carrying the spindies of said saw, a frame to which said arms are movably hung, and means for vibrating said frame, substantially as specified.

7. The combination in a shingle siding machine, of the fixed frame, means for supporting and for intermittently feeding the siding strip, a circular saw, a guide for limiting the depth of cut of said saw, arms carrying the saw spindle, a swinging frame to which said arms are movably hung, and means for vibrating said frame and for imparting forward movement to the upper ends of the saw carrying arms, substantially as specified.

8. The combination of the scoring saw, arms carrying the spindleof the same, a gage bar for limiting the forward movement of the saw, a vibrating frame to which the saw carrying arms are movably hung, an arm having a spring leg for pressing the saw forward, and means for vibrating said arm, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
