OF SAME PLACE.
WCOD POLISHING ACHINE.
SPECIFICATION forming part of Letters Patent No. 392,663, dated November 13, 1888.
Application filed September 30, 1887. Serial No. 251.149. (No model.)
.To aZZ whom, it may concern:
Be it known that 1, JAMES E. CARPENTER, of Berlin, in the county of Green Lake, in the State of WVisconsin, have invented new and useful Improvements in Machines for Polishing WVood, of which the following isa specificatlon.
My invention relates to the well-known machines used for sandpapering, and especially to the adjusting devices for determining the parallelism of the sand-cylinder and the table which overlies the same, and which is commonly known as the sand-guard, and also for regulating the depth of the out to be given by the action of the sand-paper, and also to the mechanism for imparting an axiallylongitudinal reciprocating motion to the revolv-' ing sand-cylinders, and to other parts de signed for perfecting the operation of the machine, which will be hereinafter specifically pointed out.
As the general construction of such niachiues is well known, it will be unnecessary to set out more than the portions of the machine to which my improvements are applied.
The machine to which my improvements are specially applicable is formed of a main frame carrying a series of sand-paper cylinders, the periphery of which, appearing through a slot in the sand-guard, acts upon a board which is introduced between positively-actuated feedrolls carried part in the main frame and part in a vertically and independently adjustable frame,which also carries the pressure-rolls.
In the annexed drawings, making part of this specification, Figure l is a perspective View of my improved machine; Fig. 2, a side View, partly in section; Fig. 3, a longitudinal sectional view through one of the cylinders.
The same letters are employed in all the figures in the designation of identical parts.
The main frame carries a series of preferably three sand-paper cylinders, marked, respectively, No. 1, No. 2, and No. 3. More or fewer may be employed. The adjusting mechanism, hereinafter described, is applicable to each of the cylinders and its sand-guard, and is duplicated to any extent required. To describe its application to one will therefore be 5o sufficient.
Immediately under the shaft of each cylinder I place a through-shaft, A, which projects at both ends beyond the main frame, and carries on the overhung ends swinging arms B, which are pivoted at one end to the frame, and are adjustable at the free end vertically by means of the set-screws 13 passing through lugs on the main frame. The adjustment of these set-serews regulates the position of the shaft A. YVhen this adjustment has been made, the arm 13 is confined further by a set-screw,
B passing through a slot therein. On the same shaft A, I place, immediately inside the frame on both sides, other arms, 0, Figs. 2 and 3, which are attached to the shaft by set- 6 5 screws 0, so that when the arm is turned at one end it will turn the shaft and the corre sponding arm at the other end of the throughshaft A. The arm 0 is actuated on one side by a bar, 0 attached thereto by a bolt. This bar 0 extends out through the main frame at the end of the machine, and is fastened to an extension, 0, by a bolt, 0. The extension is surrounded by a sleeve, G the two parts being connected by a male and female screw,and the sleeve is turned by a hand-wheel, As the sleeve is confined in the frame, so that it cannot move lengthwise when it is turned, the bar (1 will be drawn or thrust so as to swing the arm 0.
The arm 0 is formed with a segmental eccentric-slot, O, to receive a wrist-pin, D, attached to the vertically-sliding frame E, which carries one end of the sand-cylinder shaft, G. This frame slides in ways attached to the main frame, and is raised or lowered by the action of the eccentrioslot C on the wrist-pin D. A corresponding arm and frame at the other end of the cylinder-shaft G and shaft A similarly raise or lower that end of the cylinder-shaft. 0 As shown in Figs. 1, 2, and 3, a slot, E, in the frame E permits this to be done without interference by the shaft A, which passes through. the slot and also allows the shaft to be independently adjusted by means of the arms 13.
Similar mechanism is attached to all the sand-cylinders, so as to permit their independent adjustment in relation to the sand-guards F for the determination of the amount of the out. These sand-guards are also independ- I00 ently adjustable, with a view to establishing and maintaining their perfect parallelism in reference to the surface of the cylinders. They are iron tables or plates covering that portion of the space inclosed within the main frame, which is immediately over the sand-cylinders, and are slotted so as to permit the peripheries of the sand-cylinders to appear above the plane of their upper surface. Unless these surfaces are parallel in all parts to the cuttingsurface of the cylinder the work will be imperfect, and as heretofore constructed the part of the table opposite the middle of the slot was liable to sag under the pressure of the board, being unsupported except at the corners. Struts F are attached to the main frame by dovetailed recesses, and through the struts are, passed, at one or more places, rods F", formed with threads. A nut, F, above the strut, and another below, F, determine the elevation of the point of the rod, which bears against a flange, F on the sand-guard F. One such rod may be used by attaching a collar or head, F, to support two of the tables F where their edges adjoin.
To support the corners of the table or sandguard F, I form it with lugs F to rest upon the heads of set-bolts F, passing through lugs F on the main. frame, and with square ends beneath the lug F to receive a wrench by which they may be turned. Through the lugs F I tap set-screws F, the lower ends of which are received in a recess formed in the upper end of the set-bolt F, and so look the latter when it has been properly adjusted.
It is desirable that the sand-cylinders shall have imparted to them a longitudinally-reciprocating movement, as well as one of rotation. The former is provided in the following manner: Horizontal shafts II are hung on bear- :ings on the outside of; the main frame, carrying on the outer end a bevel-pinion, which may be driven by a corresponding miterwhcel on a transverse driving-shaft, or said shaft may be otherwise driven from any e011- venient part. This shaft carries an eccentric, H, which revolves within a frame, I-I, placed within thejaws of an arm, I, which confine it sidewise, while they permit it to play freely in the other direction. I is a cap confining the frame H The arm I is attached to a collar, I, surrounding the cylinder-shaft G. This collar is confined endwise between rings I,
fastened to shaft G by setserews which turn with said shaft, while the shaft rotates within the collar I. The eccentric H imparts to the shaft G a longitudinal reciprocating motion in its box L, in which it revolves.
K is a bracket bolted to the .main frame, which carries the boxes K of the shaft H.
It has hitherto been usual to use a series of sand-cylinders of the same size and revolving at the same speed to dress and polish the wood; but in these machines the work is imperfect, as the wood is left with a sort of fine fuzz on its surface. To remove this and more perfectly polish the surface of the wood, I in troduce another preferably smaller and more rapidly moving sand-cylinder covered with finer sandpaper, acting with a light touch upon the surface of the wood to remove such fuzz.
The sand-paper is cut into sheets of sizes proper for covering the entire surface of the cylinders and attached thereto in any suitable manner.
WVhat I claim as my invention, and desire to secure by Letters Patent, is
