JAMES L. PERRY, OF BELOIT, NVISCONSIN, ASSIGNOR TO THE BERLIN MACHINE VORKS, OF SAME PLACE.
WOOD-PLISHING MACHINE.
SPECIFICATION forming part of Letters Patent No. 449,697, dated April 7, 1891.
Application filed August 18, 1889. Serial No. 320,194. (No modell) To @ZZ whom it may concern:
Be it known that I, JAMES L. PERRY, of Beloit, in the county of Rock, in the State of Wisconsin, have invented new and useful Improvements in Wood-Polishing Machines, of which the following is a specification.
rIhis invention relates more particularly to the mechanism for adjusting the abrading cylinder and pads of awoodpolishing machine, and also to that part of the mechanism which gives longitudinal movement to the cylinders, and that which gives motion to the pads.
In the annexed drawings, making a part of this specification, Figure lis a side elevation of the machine, partly in section. Fig. 2 is a similar elevation of the other side. Fig. 3 is an end elevation, partly in section. Fig. 4 is a vertical section of one end of the machine; Fig. 5, a partial inside elevation; Fig.
6, a horizontal section of the parts shown in Fig. 5 on line :c x. Figs. 7, S, and 9 are views in detail of the oscillator and attachments. Fig. 10v is an elevation, partly in section, of the adjusting device for leveling the rolls and pads. Fig. 1l isa section of thesame on line 1/ g/ of Fig. l0. Fig. l2 is an elevation showing the device for simultaneously adj usting both ends of the cylinders and pads. Fig. 13 is a sectional elevation of the mechanism which actuates the pad, and Fig. 14 is a plan view of the same.
The same letters are employed in all the figures in t-he indication of identical parts.
A is the lower and A the upper part of the main frame.
The driving-power is 'applied at B to the oscillator-shaft C, which carries eccentrics C', working in the boxes C2, communicating oscillatory motion to the oscillator D, which is pivoted at D', at the lower end, to the frame and iieXibly connected at the upper to the cylinder-shaft. ln this, as in other cases where an eccentric is employed, a crank may be substituted for the eccentric or other known devices for changing rotary into reciprocatingA motion.
Motion is communicated from shaft C to shaft E through bevel-wheels E'. Another smaller bevel -wheel E2 on the same shaft drives a shaft F, placed vertically in the frame and carrying a crank-wheel'F', (sec Fig. 13,) the crank-pin F2 entering a sliding box F3, playing loosely in ways G', formed in the bar of the pad G, to which it communicates a horizontal reciprocating movement in the direction ofthe length of the machine, while the oscillators D communicate motion to the cylinders in the direction of the width' of the machine.A
The ends of the pad are confined between the sides of the main frame, as shown in Fig. l, where the side of the frame is represented as broken away to show the end of the pad G. As the pad can have no movement tra-nsversely to the frame and the box has onlyan end movement in the groove, it follows that the pad will move transversely to its own width and in the direction of the length of the machine.
The following is a description of the incohanism which is employed for independentlyT adjusting the ends of the cylinder-shafts, as well as the pads, both of which are called abraders, as well as for simultaneously adjusting the cylinders and pads at both ends. l-l is a vertical rod and hand-wheel for turning it, secured to the frame on the side opposite to the elevators, so that the rod can turn but not move lengthwise. The rod is screwthreaded and passes through an engaging .female thread in the end of the rack-bar H',
which slides freely up and down in suitable ways on the frame. The teeth on the rackbar (see Fig. l2) engage those of a spur-pinion l on the shaft K. The shaft K (see Fig.' 4) has an eccentric portion K', forming an enlargement between the Asides of the frame across which it extends, so as to engage on each side the sliding bars L, which pass up along the inside of the frame and carry the shafts of the cylinders or the ends of the pads, as the case maybe, it being understood that the parts are duplicated to whatever eX- tent may be required to actuate simultaneously both ends of each cylinder and each pad. The lower ends of the sliding bars L are formed to receive the boxes L', which inclose the eccentric portion K of the shafts.
In orderthat the ends' of the cylindersorpads IOO may be independently adj usted to bring them into plane, a strap M is eccentricallyattaehed to the shaft K at one end thereof where it passes through the frame. On one side the strap is enlarged to permit a slot M to be eut, as shown in Figs. l and 1l. Through the slot a set-bolt M2 passes into the frame. A segmental gear M3, of proper form, receives the threads of a bolt N, which passes through lugs on the frame and may be turned by a wrench. Bein g turned, it will cause the strap to turn on its own center and raise or depress the shaft K, and thereby raises or depresses one end of a cylinder or pad.
The connection between the oscillators and the shafts of the cylinders is made as follows, Figs. 7, 8, and 9: P represents one end of the cylinder-shaft, which is received in a box O, carried in the upper end ofthe oscillator D, and connected with the same by means of bolts or pivots O', which pass through the jaws on each side at the top of the oscillator and engage the gibs O2, which glide in grooves in the sides of the box O. I thus provide a flexible connection between the oscillator, the end of which moves in the arc of the circle, and the box or bearing of the cylinder, which moves in a right line.
The following is the provision for compensating for the wear of the box O at the ends: A thread is eut on the end of the shaft P, on which is a j am-n ut P and a collar P2, which surrounds the shaft and is provided with a set-screw P, the inner end of which enters a spiral groove P4, cut in the surface of the shaft, as shown in Fig. 9. When the collar is neatly adjusted to the face of box O, the setscrew holds itin place until, when the box may have become worn at the end, the setscrew Pis is turned enough to free the collar, which is forced against the box by turning it on the shaft, the point of the set-screw being engaged in the spiral groove, and is again secured in place by turning the set-screw. A collar on the shaft inside the box contines it and sustains the pressure of the box when forced inward by the collar P2, which holds the box against the inside collar.
IVhat I claim as my invention, and desire to secure by Letters Patent, is-
1. In combination with the oscillator D, the box O, held in jaws in the end of the oscillator, and bolts or pivots O', and gibs O2, sliding in grooves formed in the box, substantially as set forth.
2. In a wood-polishing machine, the combination, with a polishing-pad G, mounted in and held against longitudinal movementby the frame of the machine and provided with longitudinal ways, a box F3, arranged to slide in said ways, and a rotary shaft F, provided with a crank, the crank-pin F2 of which is seated in the box F3, substantially as and for 4the purpose set forth.
In combination with an abrader, its supporti 11g-arms and eccentric-shaft, the parts II, II', and I for simultaneously adjusting the shaft at both ends, and the parts' M, M3, and N for independently adjusting it at one end, substantially as set forth.
et. In combination with an abrader, arms L and eccentric, an eccentric-strap M, segmental gear M3, and threaded bolt N for adjusting one end of the abrader, substantially as set forth.
5. In combination with a cylinder and os cillator, a shaft P, box O, collar P2, pin P3, spiral groove P4, and j am-n ut P', substantially as set forth.
In witness whereof I have hereunto attached my signature in the presence of two subscrib-
