MoHNs WOODWORKING TOOL Filed Aug. l1, 1951 2 Sheets-Sheet 2 ffl f A Homey Patented Dec. 27, 1932 narran stares p ATTENTI* OFFICE ALFRED R. MOHNS, OF IIFEWVARK, NEW JERSEY .VOODWORKING TOOL Application filed August 11, 1931. Serial No. 556,441.
The present invention rrelates to new and useful improvements in woodworking tools, and more particularly 1t pertains to woodv working tools of the power driven type.
lt is one'ot the objects oi the present inven tion to provide a power driven Woodworking tool which is of a portable nature.
lt is another object of the invention so'to construct a portable power driven woodwork ing tool that it may be adjusted to adapt itself to various types of work.
A further object of the invention resides in a. novel Jrormof cutter and support thereior whereby the cutter may be removed and r cutters of various other types may be used accordance with the present invention and one of the uses thereof,
Figure 2 is a detail sectional view on an enlarged scale,
Figure 3 is a detail view taken at right angles to Figure Q, said view being partly in elevation and partly in section,
Figure 4 is a fragmentary sectional view illustrating a portion of the tool with the cutting element removed,
Figure 5 is a detail sectional view of one of the elements of the cutter,
Figure 6 is a View in elevation of one of the elements of the cutter, and;
Figure 7 is a. plan view of a blank from which one of the cutting elements is formed.
Referring more speoiiically to the drawings, the tool comprises a cutter in the form ot an endless chain which endless chain consists of a plurality ot' links l0 pivotally connected together as at 11. Each link is formed with a cutting tooth 12 and arranged in such a manner that when the links are pivotally connected to form the chain, the cutting teeth or edges 12 will follow one another in succes sion to perform the cutting operation.
Means is provided toV support the endless cutter during operation, and this means consists 'of anv auxiliary frame 13-and'an adjustable frame 14. The auxiliary frame 18 forms the support for the adjustable frame Hand said adjustable frame 14 consists of two members 15 and 16. The members 15 and 16 are slotted as at 171andreceive` bolts 18 which in turn operate in a groove orthe like 19 in the auxiliary frame 13. By this means the two members 15 and 16 of the adjustable frame may be adjusted in two'directions towards and from the auxiliary frame 13, and towards and from eachother in order that they may be properly adjusted to per# form the desired cutting operation.
The auxiliary frame 1,3 carries a driving sprocket 20 and the adjustable framel carries guide sprockets 21'and 22 on one side thereof and 23 and 24 upon the other sidethereof. The endless v cutting element passes around the driving sprocketQOand the guide sprockets' 21V to 24 inclusive.
-By reference to Figurell it will be noted that the members 15 and -lof theadjustable frame each consists of'two' -plates 25 an'd26 which are secured together in spacedrelation'by Ineansofinserts or the likev 27 and the guide spro'ckets'21 to 24 inclusive are rotatably mountedbetween these plates, the inserts being shaped as villustrated in dotted lines as illustrated in Figure 2 to'lvpermit otfree rotation of the guide sprockets.
From the foregoing itrwillV be apparent that as the driving sp-rocket 20 is rotated, the
yendless cutter will traverse a path which includes the drive sprocket Q0` and the ,guide sprockets 2l to 24, and when positioned'in engagement with the work to be operated on will perform the cutting operation in the manner illustratedin FigureQ of the'drawings.
VThe driving'sprocket 2O carries a gear 30 and said gear is of the worm type. *Meshing with the worm'gear 30 there isa-'worm gear 31 which is carried bya shaft 32 which in turn is connectedto the-armature not shown of an electric motor`33 Ato-which current is supplied by a suitableconductor'l. The
"shaft Ld2-passes 'through the vtubular part-32' and connects the motor casing with the frame 13.
I also provide means for regulating the depth of cut made by the device in guiding the device and using the same to form grooves, or for cutting or ripping lumber. Such means comprises a shoe 34 from which armsi 35 and 36 extend. The auxiliary frame 13 is secured to the arm 36 by means of a wing nut or the like 37 as illustrated in Figure 1, and the motor is connected to the arm 35 by a similar wing nut 38. yThe wing nuts37 and 38 engage suitable bolts which are slidably mounted in slots in their respective arms to provide for the adjustability of the shoe relative to the auxiliary frame 13 and the motor 33.
Means is provided tosupport the tool during operation. The horizontal bars 41 and 45 are connected together in spaced relation by the vertical bars 44 and the frame composed of these four bars is suitably fastened to the door or other member to be mortised by the device as shown in Fig. 1. The outer end of C the bar 4l Ais adjustably supported on a post by the member and a set screw 43 and a bracket 48 is connected with the frame 13 and has its sleeve 46 at its upper end to which the bar passes and as the shoe 34 ei'igages an edge of the door said shoe and the bracket 48 act to hold the device in position for cutting a mortise in the door, it being of course understood that the entire device is moved by hand toward and away from the work and that this movement of sleeve 46 slides on the rod 45.
In the present embodiment of the invention the tool is shown as cutting a lock mortise suoli as A in a door or the like B but it is to be understood that by adjustment of the members 15 and 16 of the adjustable frame, the device may be used in other connections and to cut mortises of various sizes within certain limitations. It is also obvious that the device may be used for ripping and sawing lumber merely by adjustment of the members 15 and 16 or by substitution of other members of the desired size to perform the desired operation.
As will be noted by reference to Figures 5 to 7 inclusive, the cutting element consists of links which are formed from a blank 50. The blank 50 comprises a main body portion 51 from which wings 52 extend, the wings 52 are adapted to be bent into a plane at substantially right angles to the main body portion 51 and these wings are provided with openings 54 for the reception of bolts or the like which are employed to secure a plurality of these links together to form the cutting n element. The wings 52 are provided with sharp points such as 55 which points form the cutting edgesof the individual link. An extension 57 is provided and this extension may-be rolled upon itself to provide a bearingor the like 58 which also provides for pivotally connecting the members together.
Freni the foregoing it will be apparent that the present invention provides a new and novel portable wood-working tool of the i power driven type7 and that the same is highly eflicient for the purposes intended.
While the invention has been herein disclosed in a preferred form, it is to be understood that the invention is not to be limited to the specific construction herein shown and that it may be practiced in other forms without departing from the spirit thereof.
Having thus described the invention, what is claimed as new and what itis desired to secure by Letters Patent of the United States, is:
A woodworking tool of the class described comprising a main frame, a driving sprocket carried by said frame, said frame having transversely extending grooves therein, a second frame composed of two members having each an extension formed with a slot, which extends at right angles to the groove, bolts slid-ably arranged in the `oove passing through the slot for clamping the two parts of the second frame in adjusted position on the main frame, guiding sprockets carried by the second frame, and an endless cutting member tioned sprocket and the driving sprocket on the main frame.
ln testimony whereof I aflix my signature.
ALFRED R. MOHNS.
