SPECIFICATION forming part of Letters Patent No. 393,948, dated December 4, 1888.
Application filed July 3, 1888- Serial No. 278,960%- (No model.)
To all whom it may concern: of a lower roll, C, and an upper roll, C. The Be it known that I, JAMES F. WVELOH, of two pairs of feed-rolls are represented upon Brooklyn, (Green Point,) in the county of the main frame A, and the pair of delivery- Kings and State of New York, have invented rolls are represented upon the supplemental a new and useful Improvement in VVoodframe, though for the purposes of the present 55 Planing Machines, of which the following is invention all the feed and delivery rolls might a specification, reference being had to the be upon one main frame. accompanying drawings. The feed and delivery rolls are all repre- This invention, although generally applicasented as driven from a shaft, E, which works ble to wood-planing machines, is particularly in bearings in the main frame, which car- 60 useful in the class of wood-planing machines ries a pinion, e, which gears into a wheel, which are termed surfacing-machines. e, which latter gears into another wheel, 6 The improvement consists in means, herewhich in turn transmits motion to a wheel, inafter described and claimed, for supporting c and the wheel 6 is in gear with a large and adjusting upward and downward the top wheel, 6, on the lower delivery-roll, C. 65 roll of each pair of feed-rolls in the machine, The lower delivery-roll is jourualed in bearand in the gearing, hereinafter described and ings 0; but the bearings c of the upper declaimed, for imparting motion to each upper livery-roll, C, are vertically movable, and are roll, notwithstanding its upward and downconnected by rods c with arms upon the ward movement produced either by adjustrock-shaft 0 working in fixed bearings. Con- 7o ment or by rising as the lumber passes unsequently as the upper roll, C', rises and falls der it. it is by the rock-shaft c constantly 1nain- In the accompanying drawings, Figure l is tained in parallel position with the lower dea side elevation of a surfacing-machine emlivery-roll, C. The boxes 0' here constitute bodying my invention. Fig. 2 is a plan of the supports for the upper delivery-roll, C, 75 the same. Fig. 3 is asectional elevation upon and are provided each with a socket, 0 about the plane indicated by the dotted line These sockets c of the boxes 0' atv opposite .00 as, Fig. 1. Fig. A is a horizontal section of ends of the roll, respectively, receive through two rock-shafts with which the upper feedthem cylindrical rods 0 0 These rods are rolls of two pairs are connected, as will be supported at their lower ends in bearings c 80 hereinafter described. and at their upper ends are supported in Similar letters of reference designate correbearings upon standards C erected upon sponding parts in all the figures. the framing. A designates the main frame of the ma- As planing-machines have ordinarily been 3 5 chine. B B designate the cutter-heads, and C constructed, the boxes or supports for the up- 85 C designate the feed and delivery rolls. The per feed-roll are guided directly upon the upper cutter-head, B, has its journal 6 suproll-stands; but in carrying out my invention ported in bearings 1), adjustable upward and these boxes or supports are preferably guided downward upon standards A, erected upon and sustained in position solely by the vertithe main frame. The lower cutter-head, B, cal rods 0 0 The rod 0 which is shown only 90 is represented as supported in bearings 19 in in Fi 3, is simply a smooth cylindric post,
a supplemental end frame, A but this supupon which the socket c on the box 0 at that plemental end frame constitutes no part of side of the machine slides; but the rod 0 at the present invention, and for the purpose of the opposite side of the machine consists of a this invention it is immaterial whether the screw, and the socket c, which receives that 5 bearings b of the lower cutter-head, B, are rod, forms a nut fitting the thread of the upon the main frame or upon a supplemental screw. By means of a hand-crank applied to frame. the upper end, 0 of the screw-threaded rod Two pairs of feed-rolls are represented and 0 which is squared for that purpose, the
one pair of delivery-rolls, each'pair consisting screw 0 may be turned to raise and lower the loo Mum- .1 i
box with which it engages, and inasmuch as the boxes 0 at opposite sides of the machine are connected by the rock-shaft c and its arms and rods (3 c" the two boxes c at opposite 5 ends of the roll will be raised and lowered in unison and the upper delivery-roll, C, will always be maintained in position parallel with the lower roll, C.
The upper delivery-roll, C, is weighted by means of a lever, c, which is fulcrumed at one end in a hanger, 0" depending from that part of the frame in which the delivm'y-rolls are arranged. The said lever rests in a shackle or loop, c supported by the lower end of the screw-threadcd rod c. This weighted lever c extends transversely of the machine, and
is shown in end view in Fig. 1 and in part in the plan view in Fig. 2. The weight which is thus applied through the screw 11 to one of the boxes c is through the connection of the two boxes at opposite ends of the roll with a rock-shaft, c, clearly applied to the other end of the roll, and when lumber passes u'nderthe upper roll, C, it will rise equally at both ends,
and will lift the screw c and the weight applied thereto. Upon the screw 0 is a collar,
( which, by being supported upon the hearing c prevents the downward movement of the box c, which is titted upon it, and therefore prevents the upper roll, C, from dropping down.
i I have described how the motion is transmitted to the lower delivery-roll, C, and in order to transmit motion therefrom to the 3 5 upper roll, C, I provide expansion-gearsff,
which are in gear, respectively, with gearwheelsf f upon the lower and upper rolls. The expansion-gearf is journaled in the fixed bearingf, and the gear j", which transmits motion from the wheel f to the wheclf, is
supported by the swinging links f'". This system of gears always transmits motion to the upper roll, C, whatever be its vertical position.
At the front end of the machine, as shown in Fig. 1, are two cross-shafts, F F, which are mounted in adjustable bearings'j and on which are pulleys f f. From these pulleys f f motion is transmitted, respectively, to the upper cutter-head and the lower cutterhead, B, by beltsf"f As Ihave before stated, upon the main frame A are here represented two pairs of feed-rolls, each consisting of a lower roll, 0,
and an upper roll, C. Each of the lower feed-rolls, C, is mounted in stationary bearings c, and each of the upper feed-rolls, C, is what is usually termed a broken roll, or, in other words, it is formed of two sections ar- 6o ranged end to end, as shown in Fig. 3. The boxes c, which support the sections of the upper roll, C, are not directly supported upon rods or cylindrie bars, as shown in the case of the delivery-rolls C C, which are mounted upon the supplemental frame A but the see tions C of each upper feed-roll,wl 1ich is upon the main frame A, are supported in an upper roll-frame, C.
The way in which the two roll-sections of each upper roll, C, are supported in a frame, C,whcrein they have a limited vertical movement independently of each other, I do not claim as my invention, as such features form the subject of an application forIiettcrs Patent tiled by A. 13. Hutchinson and E. F. Autenrieth on January 30, 1888, and the serial number of which is No. 262,39U.
Between the two pairs of feed-rolls C C,
and upon each main side frame, A, is a stand ard, C, and the upper rollframes, C", are upon opposite sides of thesestandards. The boxes 1: of the sections of the upper rolls, C, having a limited vertical movement in the rollframes C, are loaded by springs, as fully described in the aforesaid application of Hutchinson and Autenrieth. The upper roll-frames, C, may be considered as the supports for the upper rolls, and each frame C has at opposite ends sockets The sockets at one side of the machine I slide upon cylindric posts or rods (-7, and the sockets at the opposite side of the machine, which is represented in Fig. 1, form nuts, which receive and fit vertical scrcw-threaded rods c. The rods 0 c are fitted in lower bearings, c and in upper bearings, c, which are carried by the standards C. The screws 0 are provided with collars c, which form stops by striking against the hearings to arrest the downward movement of the roll-frames C and when the upper feed-rolls, C, and their frames C are raised by the lumber the sock ets c on the said frames at one side of the machine rise upon their guiding-rods clwhile at the oppositeside of the machine the screws c are lifted in their bearings. The upper roll-frames, C, are horizontally sustained and guided solely by the rods 0 which lit the sockets c at opposite ends thereof, and each upper roll-frame is connected at opposite ends by rods (5 with arms 0 upon two rock-shafts, c 0*. These rock-shafts have a common center, as best shown in Fig. 4, and the shaft c is tubular and receives the rock shaft c through it. The rock-sha ft; c" is supported at its ends in bearings 8 upon the frame A, and close to these hearings are attached arms which are connected by the rods c with the roll-frame which is at the right hand of Fig. 1. I
The tubular rock-shaf t 11* is loose upon the inner rock-shaft, c, and fills up the space between its arms, and this tubular rock-shaft 0* has at opposite ends the arms c, which are connected by rods 1: with the upper rollframe, C, at the left hand of Fig. 1. It; will be understood that by the connection of each upper roll-frame, C", at its opposite ends'with a rock-shaft, the two ends of that frame are caused to rise and fall in unison, and consequently the upper roll, C, is normally maintain in parallelism with the lower roll, C.
The lower ends of the two screws which are upon the main frame A,are connected by a yoke, 0 in whiclrthey are swiveled, so as to turn freely, and a weighted lever, c ,is ful-' as before stated, to the .wheel 6, and this wheel 6 gears into a large wheel, 6 upon one of the lower feed-rolls, C. The two lower feedrolls, 0, are geared together by wheels 6 upon their axes and an intermediate wheel, 6 as shown by dotted lines in Fig. 1. The sections of the upper feed-rolls, (-3, have upon them gear-wheels c and the sections of the two upper rolls are geared together by an intermediate shaft, 6 having wheels e which gear into the spur-wheels e on opposite sides. This shaft e is supported in bearings e, which extend laterally inward from one of the upper roll-frames, C and consequently as the upper roll-frames are raised or lowered by handles applied to the square ends of the screws 0 the shaft a will also be raised or lowered. The shaft e is received in a slot, e formed in one of the uprights or standards C as shown by dotted lines in Fig. 1, and motion is transmitted from one of the lower feed-rolls, C, to the upper feed-rolls, O, by expansion-gearing, which I will now de} scribe.
Upon one of the lower feed-rolls, C, is a geai wheel, 8 and upon the shaft 6 is a gearwheel, 6 \Vith both these wheels engages an expansion-gear, 6 which is supported by swinging links 6 As the shaft 6 with the wheel a upon it, rises and falls, the expansiongear 6 is maintained in constant engagement with it and with the wheel e on the lower feed-roll, and hence motion is continuously imparted to the shaft 6 and to the two upper rolls, C.
I do not here claim the arrangement of the sections of the two upper rolls, 0', those of each roll in a separate upper roll-frame, C and the intermediate shaft, e which is geared with both sections of each upper roll, as such subject-matter is included in the aforesaid application of Hutchinson and Autenreith; but I do desire to include in my invention, broadly, the supports for the upper feed-rolls for the upper delivery-roll, having sockets which are fitted upon and solely supported and guided by rods at opposite sides of the machine, one of said rods of each pair being a screw and fitting a screw-thread in the socket in which it is received; and I also desire to include in my invention the combinatiomwith the vertically-movable supports, of the upper roll-shafts of the two pairs of two rockshafts, one being hollow and surrounding the other and having arms which are connected by rods with the upper roll-supports of the two pairs, whether these roll-supports consist of vertically-movable frames, as C which support each the two sections of an upper feed-roll, or whether they consist of the movable boxes of upper feed-rolls, which are not sectioned or broken.
WVhat I claim as my invention, and desire to secure by Letters Patent, is
1. The combination, in a wood-planing machine, of two pairs of feed-rolls, the lower rolls of the two pairs being mounted in stationary boxes and the upper rolls in vertically-movable supports, of two rock-shafts, one being hollow and surrounding the other, arms on said rock-shafts, and rods whereby the upper roll-supports of the two pairs are connected, respectively, with the arms on the two rockshafts, substantially as herein described.
2. The combination, with a cutter-head, of a pair of feed-rolls, the lower roll being mounted in stationary bearings and the upper roll being journaled in supports connected at opposite ends of the roll by rods with the arms of a rock-shaft, and two guide-rods at opposite sides of the machine fitting sockets upon said upper-roll supports, whereby said supports are guided and solely sustained in all directions horizontally, one of said two rods being a screw and fitting a screw-thread in the one of said sockets in which it is received, substantially as described.
3. The combination, with two pairs of upper and lower rolls, of gearing connecting together the two lower rolls, a gear-wheel intermediate between the two upper rolls for driving both, a second wheel concentric and connected with said intermediate wheel, and an expansion-gear connecting the said second gear-wheel with a wheel on one of the lower rolls and j ournaled in swinging links, so as to transmit motion to the upper rolls whatever be their vertical position, substantially as herein described.
