IJNITED STATES PATENT OFFICE.,
JAMES A. WOODBURY, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN PLANING-MACHINES.
Specification forming part of Letters Patent No. 56,656, dated July Q4, 1866.
To all whom 'it may concern:
Be it known that I, JAMES A. VOODBURY,
view; and Fig. 3 is a vertical section through the shaft and boxes of the side cutter in the line oo of Figs. l and 2.
Like parts are indicated by the same letters in all the drawings.
The nature of my invention consists, first, in a certain novel combination and arrangement of devices by means of which the opposite ends of the feed-roller W may be raised or depressed simultaneously and without the necessity of liftin g the weighted levers E E', by which the roller is pressed upon the stock to be planed, while at the same time the said opposite ends are free to move independently of each other in a vertical line to conform to stock whose opposite edges may be of unequal thickness; and, second, in lubricating the vertical shaft H of the side cutter by means of cotton-wicking or other suitable capillary substance, which shall raise the lubricating fluid from a fountain, N, to the upper part of the box or bearing, and through an opening, d, in the same, to the said shaft, whereby, when the shaft is in motion, a constant and copious flow of the lubricating fluid is obtained from the top to the bottom of the friction-surfaces.
To enable others skilled in the art to make and use my improvement, I will now proceed to describe the construction and operation of the saine, merely mentioning those parts of the machine which are common to other planing-machines in general use.
A A are the sides, and B B are the ends of the frame. C is the cutter-head, turning on the axle G in the bearings D D; and F is the driving-pulley.
E E are the knives or cutters, attached to the rotating cutter-head in the usual manner by means of the screw-bolts f.
R is the lower feed-roll, driven by the pulley T on the axle K'. in the stationary boxes V V are gear-wheels fast to the shaft K', which en gage with gear wheels h h, whose axis is t, and j j are similar wheels, actuated by the wheels It t and turning on the axis k, m m being` links through whose extremities pass the axes t' and lr, whereby the wheels jj are supported over the wheels h h.
W is the upper or adjustable feed-roll, whose axis X turns in the sliding boxes Y Y. To the ends of this roll X are attached the gearwheelsl l, which engage with the gear-wheels jj, n a being links connecting axle X with axle 7c, as represented in Fig. l.
Z Z are large screws passing vertically through the movable cross-head B', the latter being provided with suitable internal screws to receive them, and thence through a smooth hole in the bevel-gears s and no into the top of the sliding boxes Y Y, to which they are attached by means of an annular groove and plate, as represented by the dotted lines in Fig. l, or in any other obvious and equivalent manner. In each of these screws Z Z is a vertical slot, q, in which slides one portion of a spline or pin, the other portion of which is fast in the said beveled gears, so that by turning the latter the screws Z Z will be rotated and the boxes Y Y, with the feed-roller W, will be raised or lowered, as the case may be.
In order that both of these screws Z Z may be moved equally and simultaneously, and both ends of the feed-roller W raised or depressed alike, the two beveled gears are connected by means ofthe two beveled gears tand zo, attached to a common shaft, I', which turns in suitable bearings in the arms Q Q of the caps Q Q of the uprights P P, as represented in Fig. 2.
Motion is communicated to the beveled pinion s by means of a similar pinion, r, whose axle o passes horizontally through the arm Q', as seen in Fig. 2, H' being the hand-wheel fast to said axle, by means of which it is turned by the attendant of the machine standing one side of the same.
The feed-roll W is pressed down upon the stock to be planed in the usual manner by means of the weights G' G' on the levers E.' E', which are pivoted to the arms F' of the frame, and connected with the movable crossheads B' B' by means of the rod D', bar C', and rods A' A', as clearly shown in Figs. l and 2.
1 I are the side cutters, attached, by means of screws e e, to the cutter-head J' of the vertical shaft H, which rotates in suitable boxes or bearings K L, confined to the frame A, as represented in Figs. 1 and 2. The caps L L of these boxes are provided with founta ns N N as clearly shown in the sectional drawing, Fig. 3. At the upper part of these fountains are openings d d to the shaft H, through which openings is inserted cotton-wicking or otherA suitable capillary substance b, which conducts the lubricating fluid i'roin the fountain 'N to the top of the bearing-surface of the shaft. Near the lower end of the cap Lis a recess, O, for the reception of cotton or other suitable capillary substance, to collect the lubricating duid as it deseen ds through the box around the shaftn M is a hinged cover to the fountain N.
a a c are rings turned on the shaft H, and fitting corresponding annular grooves in the box, by means of which and the pivot sets'crew g, the shaft is prevented from moving vertically.,
I ain aware that horizontal shaftin g has been lubricated by means of a capillary substance leading upward from a fountain; but I ain not aware that vertical bearings have ever been lubricated in the manner which I have described abovew'i. e., by means of a fountain arranged parallel With the vertical shaft and a capillary substance leading from said fountain to the top of the friction-surfaces.
'What I claim, therefore, as new, and desire to secure by Letters Patent, is
1. So combining the yielding feed-roll in a plani1ig"niachine with the Weighted levers which control it, and when said roll is Weighted and geared so as to raise both ends of it at once, as that when the board runs out the Weight of the levers shall be removed from said feedroll and leave it simply suspended to or by the screws, so that it; can be raised or lowered without raising or lowering the Weight of tbe levers, and when constructed and operating substantially as described.
2. So combining and arranging the yielding feed-roll of a planinginachine with the gear for raising and lowering it, and when Weighted as above claimed, as that While both ends of said roll will rise together by the gearing, yet either end thereof can yield or rock in the line ot' its length to conform to the varied thickness of the edges of the boards passed through under it, substantially as described and represented.
