SHINGLE PLANING AND SIZING MACHINE.

SPECIFICATION forming part of Letters Patent No. 465,005, dated December 15, 1891.

Application filed July 28, 1890. Serial No. 360,208. (No model.)

To all whom it may concern.-

Be it known that I, EDWIN H. TROMAN- HAUSER, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain Improvements in Shingle Planing and Sizing Machines, of which the following is a sions both in width and thickness are carried by a suitable endless revolving conveyor-platform adapted to revolve upon suitable car rier-wheels after the mannerof a link belt and sprocket-wheels. This moving platform is firmly and adjustabiy supported beneath the planer and. is divided into a number of sec tions, each independent of the other, the width of each being determined by the varying widths of the shingles desired to be manufac-' tured, several widths of shingles being made by the same machine. After passing under the planer the shingle-blankis cut up into several sections by suitable circular saws revolving between the several sections of the platform, the complete shingles being then taken from the machine and thrown into the various bins by the sorter or allowed to drop from the platform-links as they are carried beneath the carrier-wheel.

My invention consists, further, in' various details of construction and combination hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a sectional side elevation of a shingle planing and sizing machine embodying my invention,the section being taken upon the line at m of Fig. 2. Fig. 2 is a plan view thereof. Fig. 3 is a sectional end elevation of my machine, as seen from the line l/ 'y of Fig. 1. Figs. 4 and 5 are detail views of the platform-links which make up the endless revolving platform. Fig. 6 is a detail view showing the construction of the variable feed device shown in connection with the moving platform. Fig. 7 is a detail view showing the manner of disengaging the two disks of the variable feed. Fig. 8 is a detail.

Similar figures of reference are used upon like parts throughout the drawings.

As will be seen by the drawings, the revolving platform is made up of the endless chain of short platforms or links 2, adapted to rotate over suitable carrier sprocket wheels or drums and 4:, provided in suitable adj ustable bearings at the ends of the upright sides 5 and 6 of the machine. These links2 are of the pattern shown in Figs. 4 and 5, consisting of the plate 7, having the inclined upper face 8, as shown, and provided with the shoulder or foot 9, extending upwardly and bearing the notched steel retaining-strip 10,-

the screws of which are countersunk into the plates, so as to be flush with the surfaces thereof. Suitable lugs 12 and 13 are provided upon the opposite ends of the links 2, the adjoining lugs of the several links being connected by suitable rivets or bolts, the heads of which are flush with both surfaces of the lugs. The platform composed of the several links 2 is divided longitudinally, as shown, into the endless-link-

chain sections

15, 16, and 17, each longitudinal section being supported and guided by a bed-plate 18, 19, or 20, respectively. These bedplates are preferably provided wi h the downwardly-turned ends 21, serving to guide the links onto the plates, and are in turn rigidly supported between the sides 5 and 6 by suitable cross-bars or tie-beams 23 and 24 and a suitable stationary support 25, placed midway between the ends of said plates. The planer 26 is adapted to rotate rapidly in the direction of the arrow, and is belted directly to the pulley on the end of the saw-arbor 27, which carries the several saws 28, projecting up between the said sections of the platform, as shown, and adapted to cut the wide shingle-blanks into different determined widths. The spring presser-feet 29 and 30 are adapted to prevent lifting the shingles from the platform by the revolving planer-knives. Suitable spring-rollers 31 are provided upon either side of. or between the circular saws 28, and are adapted to prevent the shingles-from flying out of the saws as they are passing between the same. It is desirable to plane only the thick butt-ends of the shingle-blank. Hence the arrangement is such that the knives of the planer engage the shingle upon the platform only after the thin half of the shingle has passed beneath the same, the remaining portion bein'gthen planed down to the desired thickness. The

pitch or tilt of the platform-links as they pass form-links. The tie-beams 23 and 24 are cut off 43 below the same and. which is adapted to,

so as to just fitin between the sides of the machine, and are provided with threaded openings into which the bolts 34 are adapted to be screwed. These bolts pass through upright slots 35 in the ears 32 and 33 and may therefore be adjusted in a higher or lower position, as desired. The bolts then being tightened up clamp the tie-beams 23 and 24 against the stationary connection to support the platformbed firmly in position. The platform bed or plates are free to move over the upper edge .of the central tie-beam 25 and tilt thereon as a fulcrum. The bearings of the wheels 3 and 4 are preferably made vertically adjustable, for when the tilt of the platform plates or bed is altered it becomes necessary, or at least desirable, to raise or lower the notched wheels 3 and 4, in order that the strain upon the linkplatform may be as even as possible and in order to avoid any tendency toward raising the links from the bed-plates.

As shown, the mainpulley 40, over which the main driving-belt passes, is provided on the end of the planer-shaft. Upon the other end of this planer-shaft are provided the small pulley 41, over which the twisted belt which runs the saw-arbor 27 passes, and the small pulley 42, over which a belt passes to connect the same with the large pulley-wheel operate the large wheel 44 of the variablespeed device. This variable-speed device may be constructed as shown in Figs. 2, 6, and 7, and consists in the small friction-pulley 45, adapted to press firmly against the outer surface of the wheel or disk 44 to be revolved thereby and adapted to be moved back and forth between the center and circumference of said disk 44 by a suitable lever 46, whereby the speed of the pulley 45 is controlled at will, the speed thereof being lessened as it is moved in toward the center and increased as the friction-wheel 45 nears the edge of the large drive-wheel 44. The 1ever 46 is adapted to be locked'in position by l a suitable device 47, which is supported by the branch arms 48, secured upon the beam 49, which is in turn pivoted upon the strap 50, secured upon the'adjustable bearing of the sprocket-wheel 3, serving to drive the moving platform. The pulley 45 is movably keyed upon the shaft 51, which operates through a bearing on the beam 49 and carries the smaller wheel 52 of the miter-gear adapted to turn the notched wheel 3. In order that the feed of the machine may be quickly stopped, I preferably provide means consisting in the adjustable lever 53, secured to the beam 49, which in turn supports the bearing for the shaft 5l,wherebythe engagement between the small pulley 45 and the large disk 44 may be broken by moving out the small pulley 45 into the position shown in Fig. 7.

I will now describe the operation of my machine, first stating that when the shingles are first sawed out of the short lengths of timber they are left in the shape of'broad flat rough blanks having a tapering edge. It is now desired to cut this shingle-blank into suitable widths and to plane down that por tion of the shingle which is exposed to the weather, so that at the butt=end of the shingle the edges will present the appearance of lying nearly parallel or perhaps slanting in a direction opposite to the original taper of the shingle. I will assume that the machine is in operation. The wide"- blanks are now placed upon the links in front of the planer 26 in the position of the blanks 55 and 56, the butt-ends being placed against the notched retaining-strip 10, as shown. As the platform is moved ahead the shingles or blanks are carried through under the presser-feet 29 and the planer-knives. 'The planer-knives do not strike the thin edge of the shingle,'which first passes under the planer, and danger of the shingles being broken up by the same being thus avoided; but as the last six or eight inches of the butt-end'of the'shingle are passing through the planer strikes the same and passed from under thefirst roller3l. The

several complete shingles are now carried over the end of the machine, and,"a's the links are carried around the wheel 3, fall off up'o'n of the machine. The blank in that case is merely placed upon the narrow section, the edge being placed so as to just be cut by the outside side saw, while the other waste edge would be trimmeddown by the next saw. A machine of the size shown and described could easily be fed with great rapidity by a single man, who would place the blanks upon the platform in such a way as to make the least waste possible. For instance, if a blank were just wide enough to form two shingles of the width of the two widest sections of the platform, the operator would place the blank upon those sections rather than place it upon the two smaller sections.

As shown in Fig. 9, I prefer in practice to arrange a greater number of linked platformsections than I have shown in the preceding figures, and I arrange the sections in groups of two or more having the same width. This arrangement is clearly illustrated in Fig. 9, where the sections a b and 0 cl and efarerespectively of equal Widths, each being sup ported by a suitable longitudinal bar, as hereinbefore described. The circular saws are arranged to operate between the several sections. The advantage of this construction is that whereas a blank is often too narrow to make two shingles of thee and b widths it is wide enough to make two shingles of the c and (Z width. Again, a blank not quite wide enough to make two shingles of the a, andb width may be used on the sections 1) cf, thereby making three good though narrow-dimensioned shingles.

It is obvious that gig-saws or band-saws might be employed in place of the circular saws; but I preferably employ the latter as most convenient and inexpensive. It is fun ther obvious that in the practical construction of my machine various detail modifications would readily suggest themselves to one skilled in the art, and I therefore do not confine myself to the specific construction shown and described.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent 1.
