PLANER ATTACHMENT FOR JOINTERS.

Application led November To all lwhom t may concern:

Be it known that I, DnLnnnr M. PADDOCK, a citizen of the United States, residing atv Sidney, in the county of Shelby and State of Ohio, have invented a new and useful Planer Attachment for Jointers, of which the following is a specification.

The invention relates to a planer attachment for jointers.

The object vof the present invention is to provide a simple, inexpensive and efficient attachment, adapted to be applied to a jointer for planing and sizing various kinds of timber to an even thickness, and capable of affording the same results as are obtained by the use of a separate jointer and standard pony planen With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying' drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Tn the drawings z--Figure l is a side elevation of a planer attachment, constructed in accordance with this invention and shown applied to a jointer. Fig. Q is an elevation, the planer attachment being supported beyond the jointer to permit the latter to be used. Fig. 3 is a side elevation of the planer attachment, the shaft of the jointer head being in section. Fig. l is a Vfront elevation of the same, partly in section. Fig. 5 is a horizontal sectional view, taken substantially on the line 5 5 of Fig. 3. Fig. G is a central vertical sectional view.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

Tn the embodiment of the invention illustrated in the accompanying drawings, the planer attaehment,which consists essentially of a frame, feeding means, and an adjustable gage member, is shiftable by means of a hoisting device to and from a jointer coinprising a frame having a horizontal cutter and a table top made in two sections, located at opposite sides of the cutter and adjust- Specification of Letters Patent.

able upward and downward and toward and away from the cutter. `When the planer attachment is mounted upon the jointer, as illustrated in F l of the drawings, it converts the jointer into a self feeding planer, and when it is arrangedat one side of the jointer, as illustrated in Fig. 2 of the drawings, it permits an independent operation of the said jointer. Preparatory to placing the planer attachment on the jointer, the top thereof is cleared of the gage mechanism ll and the means usually employed but not shown in the drawings for holding the work down close to the cutter.

The vertical standard, which may be constructed of tubular or other metal, is provided at its lower end with a suitable base 3, bolted or otherwise secured to the floor at one side of the jointer and provided with an upwardly extending socket -t in which the lower end of the standard is secured. The horizontally swinging arm 2 is provided at its inner end with a vertical opening 5, receiving the upper end of the standard, which equipped with an adjustable collar (i, arranged below and supporting the horizontal arm 2 and secured to the standard by a set screw v7. rPhe horizontal arm,whieh may be mounted on the standard in any other desired manner, is provided near its outer end with a vertical. opening through' which passes a vertically disposed screw 8, provided at' its lower end with an eye 9, linked into an eye bolt l() of the planer attachment, whereby the latter is connected with the screw. The vertical screw S is engaged by a nut Il, supported by the horizontal arm 2 and equipped at the top with beveled teeth, forming a. horizontal gear l2, which meshes with a vertical bevel gear 13 of a horizontal operating shaft 14. The shaft 14, which is equipped at its outer end with a crank handle 15, is journaled in a suitable bearing 1G of an upstandine' supporting portion 17 of the horizontally swinging arm Q. rlhe operating shaft is adapted to be rotated to actuate the nut l1 through the medium of the gears l2 and 13, for raising and lowering the planer attachment to lift the same clear of the front and rear tables 1S and 19 of the jointer and to place it on the same. Then the planer attachment is lifted clear of the jointer, the

horizontal arm is adapted to be oscillated to arrange the planer attachment in the desired position.

The planer attachment, which, when in use, is arranged upon the front and rear tables of the jointer over the jointer head 20, is provided with a frame composed of spaced sides 2l and connecting top and bottom bars 22 and The sides, which are provided at their inner faces with vertical guides 2f, are preferably of flanged formation consisting of spaced vertical transverse flanges 25, a central vertical connecting web or port-ion 2G and front and rear bracing webs 27 and 28, but any other desired construction may be employed. rThe spaced vertical flanges 25 form recesses to receive vertical ribs or flanges 2S) of an adjustable gage member 30 for guiding the same. The gage member 30 is composed of a horizontal bottom 3l, upwardly extending sides 32, a central connecting web 33 and front and rear connecting webs 3l anl 35, but any other preferred construction may of course be employed. T he bottom 3l presents a horizontal lower face to the material and constitutes a rigid upper guide for the lumber.

The gage member is raised and lowered to adjust it vertically with relation to the rotary cutter or jointer head 2O by means of vertical adjusting screws 36, journaled at their upper ends in suitable bearings of the top connecting' bar 22 of the frame of the attachment, and extending downwardly therefrom and engaging interior threads of the vertical openings $37 in the side portions of the gage member. The vertical screws are equipped at their u )per ends with horizontal beveled gears 38, which mesh with vertical beveled gears 39 of a horizontal operating shaft e0, journaled in suitable bearings lll of the top connecting bar 22 and provided at its outer end with a crank handle 42, or other suitable operating device. The horizontal shaft 40 is adapted to be rotated to actuate the screws 36 for raising and lowering the gage attachment, which is equipped at one side with a pointer 43 movable vertically over a graduated index ill at one side of the attachment frame, as clearly illustrated in Fig. l of the drawings. The pointer and the graduations enable the gage member to be accurately positioned for planing the material to the desired size.

The lumber to be planed or sized rides over a lower grooved power driven feed roll 45, journaled in vertically slidable bearings f6 mounted in rectangular guides 47, depending from and preferably formed integral with the sides of the attachment frame, and consisting of spaced sides and connecting bottom portions. The bearings or bean ing blocks 4-6 are provided with threaded openings for the reception of lower threaded ends L,L8 of vertically slidable stems or pins 49, passing through guide openings 50 of bottom flanges 5l of the sides of the attachment frame and receiving coiled springs 52, which yieldably supportthe lower grooved feed roll and normally maintain the bearings f6 in contact with the upper ends of the guides 47. The upper ends of the coiled springs bear against washers 53, and the upper ends 54 of the stems are threaded for the reception of adjusting nuts 55, ar ranged in pairs and adapted to adjust the springs to secure the desired tension of the same.

The adjustable gage member is equipped with an upper idler feed roll 56, journaled in suitable bearings 57 and operating in an opening 58 of the bottom of the adjustable gage member. The gage member is provided above the opening 58 with vertical guides 59, receiving the bearings 57, and preferably consisting of vertical side flanges and a horizontal top connecting flange. The top connecting flanges of the opposite guides are provided `with threaded openings for vertical screws GO, having heads at their upper ends and connected at their lower ends with the slidable bearings 57 and adapted to raise and lower the same to position the upper idler feed roll properly with relation to the lower guiding face of the gage member.

One of the journals or gudgeons of the lower grooved feed roll carries a vertical gear Gl, meshing with a vertical pinion 62 of a stub shaft 63, which also supports a vertical gear 61 connected with the pinion 52. The gear (if meshes with a pinion 65, which is connected with a pulley 66. rlhe gear G5 and the pulley 6G are mounted on a suitable stub shaft 67,and the pulley 66 is connected by a belt 67a with a pulley 68 of a line or counter shaft 69, from which the planer attachment is driven. Any preferred arrangement of gears may be employed for securing the desired number of revolutions of the feed roll. The large gear 6l meshing with the pinion 62 permits the vertical movement of the lower' feed roll to enable the same to yield to the inequalities of the material. This vertical movement of the feed roll does not affect the mesh of the gears.

The planer attachment may be placed directly upon the front and rear tables 18 and 19 of the jointer, but it is preferably equipped with adjusting screws 7 0 and fastening screws 7l, located at opposite sides of the attachment frame. The adjusting screws 70 pierce the bottom flanges of the sides of the frame and are arranged at suitable points. They are provided at their lower ends with heads and are equipped with lool; nuts 72, located at their' upper ends and engaging the bottom flanges of the frame of the attachment. The fastening screws engage suitable threaded openings of the tables 1S and 19 of the jointer. The adjusting screws and the fastening screws, which may be of any desired number, permit the attachment to be readily leveled and secure-ly fastened to the jointer. Wvhen the planer attachment is placed upon the jointer, the gage devices of the jointer are removed to clear the tables for the reception of the planer attachment.

The automatic feeding means positively carries the lumber through the machine and eliminates all liability of the operator being injured by the knives of the machine. The material is run through the machine as often as is necessary to reduce it to the desired size, and a jointer equipped with the planer attachment will give the same results as a separate planer and a separate jointer.
