SPECIFICATIQN forming part of Letters Patent No. 335,117, dated February 2, 1886.
Application filed October-10, 1884. Serial No 145,196. (No model.)
To otZZ whom it may concern.-
Be it known that we, WILLIAM H. ELMER, and Anson P. BOARDMAN, citizens of the United States, residing at Berlin, in the county of Green Lake and State of Wisconsin, have invented certain new and useful Improve-- table of the machine, the devices for communieating a lateral reciprocating movement to one of the sand-paper cylinders while rotating, and to the general construction and arrange ment of the several parts of the machine to cooperate together, as explained by reference to the accompanying drawings, in which- Figure 1 represents an end View of the machine. Fig. 2 is a side view. Fig. 8 is a vertical section. Fig. a is a top view, and 5,6, 7, 8, and 9 are details.
Like parts are represented by the same reference-1etters throughout the several views.
Our machine lSdllOuIltGCl upon asubstantial frame, consisting of end pieces, A A, and conneeting-girts B B, which parts are rigidly bolted together. \Vays 0 O O are formed in the end pieces, A A, for the reception ofjournal-boXes D D D and E E E of the feed-rolls. D D D are the upper feed-rolls. E E are the lower feed-rolls. F F F are caps, which are bolted to the respective end pieces, A, over the ways 0, which caps are provided with adjusting-screws G G G, by which the upper fecdrolls, D D D, are adjusted at their respective ends to the desired level, when they are held in place by the lock-nuts H H H. I and l are sand-paper cylinders. The j ournal-boxes E, with their rolls E, are each adjusted at their respective ends independently of each other by set-screws a. a a, which set-screws pass through fixed screw-cut bearings 19 b b, in which they rise and .fall with the journal-boxes as they are turned toward;
the right or left, whereby said feed-rolls E E E are adjusted to the same plane with the upper surface of the bed K.
In addition to the devices for producing the independent adjustment of the feed-rolls to each other and the bed, the said several rolls, with their j carnal-bearings and adjusting screws, and the bed K are all simultaneously adjusted vertically toward and from the upper feed-rolls, as may be required for the various thicknesses of lumber operated upon,by turning the hand-wheel A to the right or left. Motion is communicated from the handwheel A to the bed K, and the several feed-rolls, with their journal-bearings, tc, supported thereon, by the shaft B, worm-gear D, pinion D. shaft E, pinions F F, irregular racks .G G, levers H H and 1 1, links J J, linkrods K K, provided with '[llllTbLlGklGS or eX- tension-nuts L L. Thus as the hand-wheel A is turned toward the right, motion is communicated therefrom through the worm-gear G and pinion D to the shaft E and pinion F, whereby said racks G are thrown up, carrying with them the free ends of the levers H and I, by which an upward motion is communicated, as mentioned, to the bed K,while, by a reverse movement of the hand-wheel,the bed 1: is lowered.
M is an inclosing-case, which is rigidly afiiXed to the shaft E and surrounds the pinion D"",and serves as a j ournal-bearin g for the shaft l3, whereby the worm-gear G is retained in operative contact with the pinion D. To the case M is rigidly affixed a lever, N, having on its free end an adjustable weight, O. Thus it is obvious that as the pinion D is turned from right to left, as is required to lower the table, or whenever the material to be operated upon is of such thickness as to force the bed or table downward, the lever N and weight 0 will be thrown upward; but as soon as the material operated upon passes from between the feed-rolls the gravity of the weight 0, acting through the lever N, causes the shaft E, with the pinion F, to turn from left {stock-operated upon, upward in position to be fed forward by the feed rolls and in contact the lever N and caseM, causes the free end of the shaft B tobe thrown upward in contact with the lug or bracket P, which bracket limits its upward movement.
Motion is communicated from the drivingpulley R to the lower feed-rolls through beveled gears S and T, shaft U, bevel-gears V and W, shaft a, and chain of gears b, and from said pulley R to the upper feed -rolls through the shaft A, bevel-gears B and O, shaft D, bevel-gears E and F, shaft h, and chain of gears G G G G G, the two intermediate gears at the respective ends of the rolls serving as idlers for transmitting motion from one roll to another. The upper end of the shaft U is provided with a crank, .H, which operates in a slot, 9, in the free end of the lever I. The opposite end of the lever I is pivoted at a fixed point to the frame by bolt J upon bracket K. The center of the lever I is attached toasleeve, K,which surrounds the shaft L, to which it is loosely fitted between the collars M M. obvious that as the shaft U revolves, the free end of the lever I is caused to vibrate toward the right and left with each revolution of the crank H, whereby the shaft L is caused to reciprocate longitudinally with the polishingcylinder I, which is rigidly affixed thereto, while it is being rapidly rotated in contact with the material operated upon, space being left between the respective ends of said cylind'er andits supporting-frame to permit of such reciprocating movement, whereby the points of contact of the sandpapered surface of the polishing cylinder I will be caused to cross and recross those of the other cylinder, 1, and a more perfect finish thereby given to the surface operated upon.
A detail of the device for attaching the lever 1 to the shaft L is shown in Fig. 8.
A detail of the device for communicating motion from the shaft U with the lever I and shaft L is shown in Fig. 5.
Motion is communicated from the motive powerto polishing-cylinders I I by separate belts operating upon pulleys O and P.
The object of the turn-buckles L is to adjust one end of the bed K higher or lower than the other, as may be required for polishing tapered stock.
,To permit of the upward and downward movement of the bed or table of the machine, with its feed-rolls and beveled gears V and W, without moving the shaft U, it becomes necessary to provide for the upward anddownward movements of said pinion V while be- Thus it is ing rotated in contact with the gear W on said shaft U. To accomplish this end, the pinion V is provided with a feather or spline, A, which operates in a groove, B, which spline and groove cause said pinion V to rotate with said shaft U, while it is free to move upward and downward upon it. The gear V is retained in operative contact with the gear W at all times by the collar or bracket 0. The rear side of said bracket 0 is provided with a socket, D, for the reception of the front end of the shaft a, (shown in Fig. 7,) upon which shaft 0 the gear W is mounted. Shaft U is loosely fitted so as to freely turn in the upper end of the collar 0'. The lower end of said collar 0 is connected with the gear V by a collar, E, which operates in a groove formed in the sleeve G. The collar F' is attached to the bracket 0 by set-screws H H. The sleeve G is cast with said gear V, details of which are shown in Figs. 5and 6.
Having'thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. In a wood-polishing machine, the combination, with the polishing-cylinder I and its supporting-shaft L, of the vibrating lever I, pivoted at a fixed point at one end to the supporting frame or bracket, and centrally pivoted to a collar or sleeve surrounding said shaft between side bearings formed on said shaft, crank H, operating in a slot in the free end of said lever I, and shaft U, connected by gears with the operating mecha'n- 3.
