sPEcIFIcATIoN forming part of Letters Patent 110.652,466, dated June 26, 1900. Application ledJanuary 27, 1900. Serial No. 2,968. (No model.)
.T @ZZ whom it may concern:
Be it known that I, JOHN R. THoMAs, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new andv useful Improvement in Feeding Devices for` Woodworking-Machines, of which the following is a speciiication.
My invention relates to feeding devices for woodworking-machines, and has for its object the providing of a device of the character described which is easy of operation, in which frictional resistance to yield of the feeding-roll is minimized, and which is compact and durable in construction.
My invention consists in providing a feeding-roll operated by gearing hung in an arm or housing swinging from a point at greater distance from the roll than the gear nearest the roll-gear further, in providing a feedingroll with a plurality ofswipnging connections having relatively stationary orfiXed axes in different planes; further, in providing a feed'- ing-roll adapted to be raised and lowered and operated by expansion-gearing and hung in a housing swinging from a point whose transverse vertical plane is 'at a greater distance from the roll than the transverse vertical planes ofV the axes vof the expansion-gears;
further, in arranging a feeding-roll to beoberated by expansion-gearing and journaled in the end of a swinging arm extendingabove` and beyond the expansion-links, and, further, in the parts and inthe construction, arrangement, and combinations of parts hereinafter more fully described and claimed.
In the drawings, Figure 1 is a side elevation of my improved device as applied to-a planing machine frame. Fig. 2 is a plan view of the same. Fig. 3 is a detail in central transverse section, showing the adjusting-screw connections on the line of Fig. l; and Fig. 4 is a detail of the upright link and connections, shown in cross-section.
I have shown and shall describe my improved feeding device in connection with the frame o f a so-called Wood-planing machine.
A represents the frame, in which a roll B may be journaled in suitable manner, as by having its shaft 1 take into bearings 2.
. C is a bed or work-supporte The-roll B l may be given adjustment with relation to the work-support. Itforms, preferably, the rigid roll of a pair. It may be operated from a shaft 3, receiving motion from a suitable source ofpower, carrying a pinion el., meshing with a gear 5 on the roll-shaft.
D is a yielding feeding-roll and in the construction shown cooperates with the roll B to feed the stock, the roll D being given adjustment to and from the roll B and yielding to inequalities in the stock. The roll D is hung o'na shaft 6, journaled in bearings 7. These latter bearings are' supported by long arms 8, swinging from a point beyond the eX- pansion gearing, hereinafter described, to give the roll a substantial vertical adjustment, relieved of all sliding resistance. I prefer to connect these arms at the roll ends by a hood 9, which may take over the roll, and at the other end by a sleeve to form a housing 11, 'swinging in parallel lines. The roll-bearings are preferably rigid with relation to the housing. The arms may be connected in other suitable ways.
The housing may swing on a shaft or rod 12, connecting with the frame, as in bearings 13 in lugs 13X.I The roll D is operated, preferablyLat `each end thereof, from a gear 14 on the shaft 1, which meshes with a gear 15 on a shaft 1G. A link `17 takes about the shaft 16 at one fend, forming a bearing 18 for the shaft, and is in turn j ournaled in the frame by having asleeve 18X vthereon taking into la bearing 19 in the frame.
The gear 15 meshes with a gearZO, mounted on a shaft 21, Which'is journaled in'a bearing 22 in the other end of thelinkl. The gear in turn meshes ,with a gear 23 of the roll- D. A link 24 connects the gear20 with the rollfgear 23, as byhaving an eyej25 thereof take'about a; j ournal 26 on the bearing 22, the other end of the link being preferably connected to the roll-bearing in a similar manner. The manner of gearing the roll D presents a suitable expansion device for operating the latter roll tocompensate for various thicknesses of material to be operated upon and for varying thicknesses in the samepiece. The stationary axis for the swinging connections of the expansion device with relation to the frame may be the axis of the bearing 18 or the roll B or other desirable part.
IOO
As stated, the bearings for the roll D are located in long arms or housing, which swing from the frame from a point preferably at greater distance from the roll than the expansion device. or gearing immediately connectingwith the roll-gear. The arm or housing is swung to vnormally-determined positions for adjustment to thickness of stock by means of an adjusting-screw 30, connecting with the frame and with a trunnion connection on the arm. An adj usting-screw is preferably at each end of the roll. It takes intov an elongated nut 32, sleeved in a shell 33. A shoulder 34 and nuts 35 prevent longitudinal movement of the elongated nut relatively to the shell, while permitting the turning thereof, the nuts 35 permitting its removal. The elongated nut also carries a gear 36, which meshes with a pinion 37, secured to an adjusting-shaft 38, journaled in the shell, the adjusting-shaft having a wheel or crank 39. The shell has trunnions 40,hung with relation to the arm, as by having a strap 41 taking about the shell and secured to the arm,- the trunnions taking into seats 42 43 in the arm and strap. The screw-shaft 30 has a collar 31, by which it is seated with relation to the frame, and it also connects with a tension device-"for instance, a lever 44, pivoted to the frame at 45 and carrying a weight 46.
If it is desired to adjust the feeding-roll in my improved device, the adjusting-shaft is turned, which turns the elongated nut in the shell and causes the adjusting-screw to take into the nut to greater or less extent and varies the distance between the roll D and the roll B. The roll D will swing from the pivoted end of the arms or housing, the links of theV expansion device swinging at the same time to the new normal position of the roll D. The roll D also yields from the same swinging-point of the arms or housing to variations in thickness in the stock against the action of the tension device.
In myimproved device all slides and straight sliding contacts are avoided, making the action of my improved device especially delicate, while providing a powerful construction. Binding of parts is prevented and even wear of parts is assured. The yielding feed- 'ing-'roll is given a parallel lift and swings from a point at comparatively-great distance therefrom and is caused to rise and lower with relation to the rigid feeding-roll, in substantially the vertical plane of the latter, while rockingly connected with the frame throughout.
By means of myimproved construction also a greatly-increased rate of feed may be obtained with greater intimacy of contact between the rolls and stock.
It is obvious that changes may be made in the constructions I have preferred to show without departing from the spirit of my invention. v
