GEORGE A. ENSIGN, OF DEFIANOE, OHIO, ASSIGNOR TO THE DEFIANOE MACHINE NVORKS, OF DEFIANCE,
OHIO, A CORPORATION OF OHIO.
SPECIFICATION forming part of Letters Patent No. 688,076, dated December 3, 1901.
Application filed April 23, 1901.
To on whom it may concern.-
Be it known that I, GEORGE A.ENsIGN,a citizen of the United States, anda resident of De fiance, in the county of Defiance and State of Ohio, have invented a new and Improved Felly-Planing Machine, of which the following is a full, clear, and exact description.
The invention relates to woodworking machinery; and its object is to provide a new and improved planing-machine more especially designed for simultaneously dressing both sides of fellies for vehicle-wheels to reduce the fellies to the desired width and without the aid of skilled labor, the machine being arranged to automatically feed the telly to and between two adjustable cutter-heads to insure true and uniform planing of both sides either parallel or to bevels and to give convenient access to the cutter-heads whenever it is desired to inspect, adjust, or repair thesanie.
The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims. 7
A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 is a perspective view of the improvement. Fig. 2 is an enlarged plan view of the same. Fig. 3 is a sectional side elevation of the same on the line 3 3 in Fig. 2. Fig. 4 is a cross-section of the same on the line at 4 in Fig. 2, and Fig. 5 is a sectional plan view of one of the presser-rolls on the line 5 5 in Fig. 3.
The improved folly-planing machine is mounted on a suitably-constructed bed A, on which is secured an upright A for saddles or slides 13 B to move in vertically, said slides carrying bearings C C for the cutterhead spindles D D carrying at their forward ends the cutter-heads D D of usual construction. The bearings O O are adj ustably held on saddles B B by bolts E, extending through angular slots 0 in said bearings and engaging the saddles B B. Thus when the bolts E are loosened the bearing 0 may be adjusted so as to bring the cutter-head spindles D D Serial No. 57,109. (No model.)
either into parallel or into angular positions relatively to one another for planing the side of the folly either parallel or to bevels, as the case may be. The saddles B B are vertically adjustable by means of screw-rods F F, mounted to turn in suitable hearings on the top of the upright A, said screw-rods screwing in suit-able nuts secured to or formed on the saddles B B. A crank-arm F can be engaged with the upper polygonal end of either screw-rod F or F, so as turn the same to the right or the left and move the corresponding saddle B or B,and with it the bearings O O, spindles D D, and cutter-heads D D, up or down, according to the direction in which the screw-rod F or F is turned. Thus the cutterheads can be brought nearer together or farther apart, according to the width of the folly to be planed. On the cutter-head spindles D D are secured pulleys G G, of which the pulley G is connected by a crossed belt G with a pulley G on a counter-shaft H, and the pulley G is connected by a straight belt G with a pulley G likewise secured on the counter-shaft H, so that when the latter is rotated rotary motion is given to the cutterhead spindles D D and their cutter-heads D D to simultaneously plane the sides of the folly to the desired width.
The felly to be planed is held on a table A and is pressed with its peripheral face against driven horizontally-disposed spaced feed-rolls I I by revoluble similarly-arranged presserrolls J J engaging the inner face of the folly, the latter being held down to the table by a presser-foot K, secured to a weighted lever K, fulcrumed at K on the bed A. The vertical shafts I I of the feed-rolls I I are journaled in suitable bearings carried on the bed A, and.
on the lower ends of said shafts are secured bevel gear-wheels L L, in mesh with bevel gear-wheels L L secured on a transverselyextending shaftL, journaled in suitable bearings attached to the bed A. The rear end of the shaft L (see Fig. 2) is connected by a bevel gear-wheel LZwith a bevel gear-wheel L secured on a shaft L geared by a pinion L? with a gear-wheel L on a longitudinallyextending driving-shaft N, journaled with the shaft L in suitable bearings carried on the bed A. The driving-shaft N is provided with fast and loose pulleys N, connected by belt and pulleytnot shown) with the countershaft H, so that when the latter is rotated a simultaneous rotary motion is given to the cutter-heads D D by the means previously described and a corresponding rotary motion is given to the feed-rolls I I by the mechanism above set forth. The presser-rolls J J are mounted by ball-bearings (see Fig. 5) on vertically-disposed spindles J J held transversely adjustable in slotted slides O O, having their bases 0 O mounted to slide longitudinally on guideways carried by a plate P, held adjustably in the direction of the movement of the bases 0 O by a screw-rod Q on a support R, removably secured to the bed A by a bolt R, as is plainly indicated in Figs. 3 and 4;. The slides O O are pressed on by springs S S, attached to a cross-pin P carried by an arm P, secured to the top plate P, (see Figs. 2 and 3,) so that thepresser-rolls J J are held by the tension of the springs S S in frictional contact with the inner face of the felly to press the same firmly in engagement with the feed-rolls I I. As the latter are positively driven it is evident that the felly is fed along, and at the same time the cutter-heads I) D act on the sides of the felly, so as to plane the same to the required width. The inner sliding movement of the slides Q 0 is limited by stops 0 on the'slides engaging the outer end of the arm P, so that the presser-rolls J J are not liable to move into the path of the cutter-heads D when no felly is under treatment in the machine.
When the machine is in use and the operator places a felly on the table A and pushes the same between the revoluble feed-rolls I and the opposite presser-roll J, then the felly is fed along to and between the cutter-heads D D, so that the latter plane the sides of the felly to the required width and shape. As the felly proceeds it passes with the planed end between the rear feed-roll I and the presser-roll J, so that when the rear end of the felly has left the feed-roll I and the presserroll J it is still fed transversely to allow the cutter-heads D D to finish the rear end of the felly, the latter being moved to the rear by the feed-roll I and the presser-roll J. At this time a new unfinished felly is placed on the table A and passed by the operator between the rolls I and J and the above-described operation is repeated, it being understood that the operator can feed one felly immediately behind the other through the ma chine, so that a Very large number of fellies can be finished in a comparatively short time.
In case it is desirable to inspect, adjust, or repair the cutter-heads D D the operator releases the bolt R and moves the support R, with all parts attached thereto, from the machine, so that convenient access is had to the cutter-heads for the purpose mentioned. As soon as the necessary repairs are made the support R is placed back in position on the bed A and secured thereto by the bolt R,
with all the parts immediately in proper positionto again start up the machine.
From the foregoing it is evident that the machine is Very simple and durable in construction, is not liable to easily get out of order, and the adjustments are very few and simple, so that the several parts can be set to the proper position by an ordinary attendant without the employment of skilled labor.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A felly-planing machine having cutterheads, driven feed-rolls for engaging the periphery of a felly, presser-rollsfor holding the felly to the feed-rolls, and a removable support carrying said presser-rolls and in which the presser-rolls are adjustable toward and from each other and toward and from the feed-rolls, as set forth.
