To @ZZ whom, it may concern:
Be it known that I, GEORGE W. LOMBARD, a citizen vof the United States, residing at Testal minster, in the county o1"` Worcesterand State of Massachusetts, have inventedrcertain new and useful Improvements in Guiding Mechanism for Rattan-SplittingMachines; and' I declare the following to be a description of'my said invention, suiiiciently full, clear, and exact to enable others skilled in the art to which it appertains to'make and use the saine, reference being had to the accompanying drawings, which forma part of this specification.` The object of my present invention is to provide a simple, practical, and efficient mechanism for centering and guiding rattan infront ofthe working tool or cutters in rattanfsplitting machinery, which guide mechanism can be conveniently adjusted, easily operated, and economically made and maintained in working condition. These objects I attain by the mechanism illustrated and described, the particularsubject-matter claimed boing hereinafter defi`k nitely specied.
In the drawings, Figure lis a front view of my improved guiding mechanism, with a portion of the support-bar shown in section. Fig.v
2 shows a plan viewof the guide mechanism in connection with the splitting-cutter and feedrolls, and Fig. '3 is a vertical section through one of the guidedevices.
In referring to parts, A designates asupportbar, which rest-s up on two screw-threaded studs, B, tted in the bed or table T, to which the ybar is retained by bolts C, which passthrough slots c in the bar and screw into the bed T, as indicated.`
D D indicate grooved rolls or devices for guiding the rattan to the splitting cutter or tool S. Said rolls are mounted on studs d, fixed inthe top of swinging arms or guide-blocks E, that are pivoted by studs f to the bar A, upon the top surface of which said swinging blocks have bearing. The pivots f are located sufficiently far in advance of the rolls D to permit of said rolls swinging apart, to allow for'irregulai-ities of the material passing between them. The two blocks E are provided 'with gear-teeth e, which mesh together in the manner illustrated, so that any Swingin g action of the parts or opening and closing of the guides will be L uniform at both sides of the central lin'e, 'thus accurately centering the rattan and directing it into the axis of the splitting-cutter S, which latter is located lin rear ofthe rolls D and'sup- .ported on the bed or frame in the ordinary manner. A at metal spring, H, oi'vC form or horseshoe shape, is arranged around the pivoted ends of the blocks E, with its ends hh pressing inward the rear ends of said blocks E at a position below the guide-rolls D, the reaction being from one guide against the other through the spring H. Screws I are arranged through the ends of the spring H, the points of which enter depressions in thepouter surfaces ofthe backs. Said screws I serve to retain the sprin g in proper relation with the part-s, and also for regulating the tension of the spring or pressure exerted by the guides against the material passed betweenthem. Eccentric bushings F are arranged laround the studs or pivotbolts f, within the arms or blocks E, whereby v the parts can be adjusted to takeup any looseness or backlash between the gear-teeth e, orfor regulating the relative alignment of the axes of the guide-arms E with each other. Said eccentrics F are made slightly higher than the thickness of the blocks E so that the stud f, when screwed down, will clzamp the eccentric bushing F firmly in position for holding it stationary, while leaving the arms E free to swing on the surface of the bushing.
For facilitating adjustment of theaxial centers, screws m are arranged'in the parts E, that may be turned in against the eccentrics F, for retaining them in relation to the arms E whilel effecting adjustment, and before the studs f are turned down to clamp them in place by endwise pressure. After the studs f are screwed down, the screw m may be 'loosened to release the parts.
The location of the feed-rolls for forcing the rattan through the machine in relation to the guide devices and cutter S is shown by the circles K. Said feed-rolls may be constructed and operated in any suitable well-known manner, as heretofore employed for passing rattan through the stripping-machines, and any de-V sired number of rolls K may be used, the splitting being effected in the ordinary manner.
Vertical adjustment of the guide devices is effected by loosening the bolts C and turning the screw-threaded studs J3 to elevate or depress the bar A, said studs being provided with neck portions b, that extend up through slots a in the bar A, with their ends iitted to receive a screw-driver or wrench. The slots a permitlateral adjustment ofthe bar and guides, as desired.
By constructing the mechanism as shown and described a very simple, durable, and efiicient guide and centering apparatus is produced, readily adjustable and convenient for use, and not liable to become deranged or get out of working order.
IVhat I claim as of my invention, and desire to secure by Letters Patent, is
l. In a rattan-splitting machine, the combination, with rolls which guide thematerial to the splitting-cutter, of the guide-supporting arms pivoted for swinging action and connected with each other byintermeshing gear-teeth e, formed 011 arcs of circles coincident with the pivotcentcrs of said arms, and means for adj usting the relative distancebetween their axes of mqtion, substantially as shown and described.
2. lIhe combination, with the swinging arms or blocks geared to each other, and provided with devices for guiding the rattan to the splitting-cutter, of a flat pressure-spring cxtending around the pivot-heads in C form, with its ends pressing against the outer sides of the blocks, in the manner set forth.
3. The combination, with the swinging blocks or arms, pivoted as atf, and toothed together for simultaneous action, and provided with means for guiding a rattan to the splitting-cutter, of the fiat metal spring arranged as shown, and provided with adj listing-screws,
the points of which enter depressions on the exterior of said arms for retaining and regu- 4o lating the parts, substantially as set forth..
4. The combination, with the swinging arms E, geared together, and carrying devices for guiding the rattan to the splitting-cutter, of the support-bar A, adapted for vertical and 45 lateral adjustment, upon which said arms are pivoted and supported, as hcreinbefore set forth.
In a machine for splitting rattan, the combination, with the support-bar A, having the 5o guiding devices mounted thereon, of the screwthreaded studs B, fitted to the bed or frame for upholding said bar, and the clamp-bolts C, substantially as shown and described.
6. The combination of the guide-blocks piv- 55 oted for swinging action, and connected with each other for uniform operation by intel'- meshing gear-teeth, and means for adjusting the axis of their swing movement to compelr sate for wear in the said gear-teeth. 6o
7. In a guiding device for rattan-splitting machines, an eccentric bushing, F, in combination with the pivot-studs f and guide-blocks E, provided with intermeshing gear-teeth c, as and for the purpose set forth. 65
8. rlhe combination, with the studs f and guide-blocks E, of an eccentric bushing, F, oi' slightly greater height than the thickness of the block, whereby said bushing is adapted to be clamped in position by said stud while the 7o block is free to swing thereon, .as set forth.
Vitness my hand this 7 th day of November,
GEORGE V. LOMBARD.
