mwwtoz chines R. England STATES PATENT OFFICE To all whom it may concern .2 Be it known that I, JAMES R. ENGLAND, a citizen of the United States, residing at Golumbus, in the county of Muscogee and State of Georgia, have invented new and useful Improvements in Plani and J ointing Machine Attachments, ofw ich the following is a specification.

An object of the invention is to provide aplaner attachment for planing and dressing material, such as wood or the like without endangering the body of the operator.

Among other features, my invention embodies a device for planing and dressing wood or the like to present beveled sur-.

faces, thus constituting a jointer attachment, my device being also operable to plane strips of wood and the like in the usual manner.

In the use of planers and jointers, the operator ofttimes exposes himself to the cutting action of the swiftly operating blades in that when small strips of wood are planed and dressed, it is necessary for the operator to feed the strip into the machine by holding the same firmly upon the bed lates ofthe machine with the hands, thus ringing the hands in close proximity with the cutting blades as the strip is fed through the machine. I

In my device I provide a means whereby when the Wood is* fed into the machine, toward the cutting blades, the wood is held firmly against the bedplates of the machine and, should the cutting blades strike a knotty portion of the wood, the wood will be prevented from springing upwardly and away from the cutting blades, while at the same time the operator need not bring hisv hands in close proximity with the cuttin blades, inasmuch as the above-'mentlone means, holding the wood firmly against the bed plate and in cutting en agement with the cutting blades only necessitate the use of the operators hands in initially feeding the wood toward the machine, the rotating action of the cutting blades, when the wood is firmly held against the same, being of sufficient force to feed the wood across the bed plates of the machine when an edge of the strip has been brought into engagement with the cutting blades.

A further disclosure of my invention embodies the use of a plurality of bed plates mounted on a frame and spaced a distance apart with cutting blades revolubly mount- Speeification of Letters Patent. Application-filed November 2, 1911.

mounted on theframe and adjustable to aid the woodor strip, which is to in retaining be planed, 1n enga ement with the cutt' blades, a jointer p ate adjustably mounted on the said bed plates and movable to accommodate'strips of. wood or the like for the pu pose of facilitatin strips toward the cutting blades so that the same will cut a beveled surface thereon,

spring-actuated means being provided on the feeding of the the said jointer plate for holding the strip against the j ointer plate and pressing downwardly on the same to retain the stripin cutting engagement with the cutting blades.

Reference is to be had to the accompanying drawings constituting a part of this specification, in which similar characters of reference denote corresponding, parts in all the views, and in which-- Figure l is an end view of my device.

Fig. 2 is a plan view. Fig. 3 is a vertical sectional view taken on the line 33 in Fig. v

2, looking in the direction of the arrow.

Fig. 4 is a vertical sectionalview taken on a the line 4-4 in Fig. 2, looking'in the direction of the arrow. Fig. 5 is a fragmentary vertical sectional view taken. on the line 5 -5 in Fig. 2, showing the manner of mounting the roller frame. Fig. 6 is a fragmentary perspective view of the jointer plate showing the spring actuated means for retainin the strip of material on the bed plates 0 my devlce, whenit is desired ,to produce a beveled surface on the strip.

Referring more particularly to the views, I provide .a plurality of bed plates 10 mountedon a frame 11 and having. their inner ends spaced apart, a series of cuttin blades 12 being rigidly secured to a sha l3 journaled on the frame 11 with the cutting edges-of the blades adapted to extend upwardly a slight distance beyond the surfaces of the bed plates, and in the space between the inner ends of the bed plates, the shaftl3 being provided with a suitable pulley 14 adapted to receive a belt for connecting the shaft with suitable driving mechanism for rotating the shaft to operate the blades 12.

Rigidly mounted on the bed plates 10 is 1 hangers are rollers a frame 15, the said frame being mounted to extend over and above the cutting blades 12 and provided witha horizontally extending cross piece 16. Mounted to threadedly extend through the cross piece 16 1s a screw 17 provided at its upper end w1th a handle 18 and at itslower end with a circular head 19 loosely mounted'in a-journal 20 secured" to the under side of a roller frame 21,

mounted within the frame 15 and movable vertically relatively to the bed plates 10. Hangers 22 are dependingly mounted on the roller frame 21 and joumaled on the said 23 thesaid rollers bein mounted to extend transversely to the be plates 10.and arranged horizontally so that when a piece of material is -mounted on the surfaces of the bed plates and fed toward the cutting blades 12, the roller frame 21 can'be'moved downwardly-by o erating a handle 18, thus engsiging the re ers 23 with the up or side 0 the iece of material, to press ownwardly on t e same and retain the lower side of the piece of ma-, terial in contact with the cutting blades 12, which revolving at a h' h rate of s eed, dress the undersurface 0 the piece 0 material, as will be readily understood.

Mounted to swing on the free ends of the frame 15 are bear ng members 24 havin bearing rollers 25 journaled thereon an ivotally connected to the lower ends of the bearing members 24 are segmentally shaped slotted adjusting. members 26, suitable thumb screws 27 being mounted to extend through slots in the said ad'usting members and having connection with the frame 15 so that the rollers 25 can be adjusted at thus permittin angles to the horizontal and secured in rigid position by means of the thumb screws, suitable graduations being provided on the adjusting members 26 to permit of adjusting each of the rollers to the same degree of angularity with respect to the horizontal.

Rigidly secured to one of the bed plates 10 are uprights 28, provided with slots 29 having thumb screws 30 extending therethrough and mounted in the slotsof the uprig ts are guides 31, having thumb screws 30 passed through slots 32 therein, of an adjustment of the guides relative y to the uprights 28, suitable graduations being provided on the said guides for relatively adjusting the same for a ur ose that will be hereinafter more fully isc osed.

A jointer plate 33 is provided with bearings 34 having ivotally connected thereto,

guldes 31 and mounted. on one of the bed plates 10,adjacent the the inner ends 0 the uprights 28, are adjustable stop members 34, the said stop members being provided with slots 35 through which thumb screws 35 are extended, the rear side of the said jointer plate 33 being 1 adapted to abut against the stop members 34 to limit the outward movement of the jointer plate. Slidably extended through a transverse opening in the jointer plate 33 is a circular ar 36 provided with a head 37 having a leaf sprin member'38 secured thereto, the free end 0 the member 38 bein inclined downwardly and the said bar 36 being adapted'to be retained in rigid position by a thumb screw 39 mounted on the jointer plate 33 and adapted to engage the bar 36, thus also rig idly positioning the member 38. r In the use of my device when it is desired to the usua manner, the mentioned stri of wood is mounted on one of the bed p ates 10 and is fed inwardly to within a short plane or dress a strip of wood in distance of the cutting blades 12, which will be engaged by the cutting bladesiwhich revolving at a hi h rate of spec will dress the under sur ace of the wood, the rotating action of the cuttin blades being of suflicient force to feed t e strip of material along the bed plates 10 so that the entire under side of the wood will be pro erly planed and dressed as' will be rea ily understood. When it is desired to provide a piece of material with a beveled surface, the rollers 25 are adjusted to the rob desired angle by means of the adjusting members26 and the jointer plate 33 is then moved so that theinner plane surface thereof will abut against the said rollers, the said jointer plate being then inclined at the same angle as the rollers, after which the thumb screws extending through the slots of the guides 31 are moved to rigidly secure the guides relatively to the uprights 28- and.

the stop members .34 are then slid inwardly so that their inner ends abut against the outer face of the jointer plate, the said stop members being then secured in rigid os1- tion to limit the outward movement 0 the jointer late, A strip of wood to be provided wlth a beveled surface, is now placed against the inner face of the jointer plate and moved inwardly into cutting engage ment with the blades 12. As an end of the strip of wood passes beneath the head 37 of the bar 36, the free end of the leaf spring member '38 will engage the upper edge of the wood and press downwardl on the strip of wood to retain the same in cutting strike a knot or cross grain in the wood, while at the same time the flexibility of the member 38 will permit of a sli htupward movement of the strip of woo cuttin blades strike a hardened portion thereo thus preventing the strip from splitting or breaking. It Wlll bereadily seen that a strip of wood having a plane face thereof lying against the inner side of the jointer plate, which haspreviously been adjusted to a desired angle will cause the cutting blades to engage an edge of the strip of wood to cut away the same and present a beveled surface. In this manner strips of wood and other materials can be easily and quickly provided with beveled surfaces, the jointer plate 33 being adjustable to any convenient angle and the provision of the member-38, engaging the strips of material to retain thesame in cutting engagement with the cutting blades, will not necessitate the operator placing his hands on the strips of material, to hold the same in cutting engagement with the cutting blades, thus preventing the mutilation of the hands of the operator by the cutting blades, inasmuch as the operators hands will at no time come sufliciently close to the cutting blades to endanger the same.

From the foregoingdescription it will be seen that a device is provided for planing and dressing pieces of material having plane surfaces and for providing pieces of material with beveled surfaces, the rollers 23 being adapted to retain the pieces of material in engagement with the cutting blades when the same are dressed and planed and the said leaf spring member beingadapted to retain the strips of material in engagement with the cutting blades when beveled surfaces are provided on the said pieces of material, the said rollers 23 and the said leaf spring member 38 being cooperative to retain large pieces of material in cutting engagement with the cutting blades when it is desired to plane or dress the same or provide the large pieces of material with beveled surfaces or edges.
