NE-FOURTH TO J. W. BREM, OF SAN DIEGO,
MORTISING-TOOL.
Specication of Letters Patent.
Patented Feb. 16, 1909.
To all whom it may concern:
Be it known that I, Josnrrr ANDERSON, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Mortising- Tools, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to an improvement in mortising tools and more particularly to a mortising tool designed for use in forming hinge seats in doors, door jambs and the like.
The object of the present invention is the provision of a tool of this character which may be readily adjusted for cutting hinge seats of various dimensions.
Other objects of the invention will be apparent from the detailed description hereinafter when read in connection with the accompanying drawings forming a part here of, wherein a preferable embodiment of my invention is shown, and wherein like letters of reference refer to similar parts in the several views.
In the drawings, Figure l is a longitudinal section of my improved mortising machine. Fig. 2 is a side elevation. Fig. 3 is a section on line 3 3 of F ig. l. Fig. 4 is a section on line 4 4 of Fig. l. Fig. 5 is a section on line 5-5 of Fig. l, and Fig. 6 is a section on line G 6 of Fig. l.
Referring now more -particularly to the drawings, A designates the frame of my improved tool, which comprises a base a, the central portion of which is cut away as at a, and the walls a2 extending upwardly from the sides of the base cz. The extremities of the base a. of the frame A are provided with downwardly projecting lugs a3 extending transversely thereof, which form supports for the frame so that the same may be moved readily longitudinally over the work.
The walls a2 of the frame are provided on their inner surfaces adjacent one end of the opening in the base a of the frame with vertically disposed guides Z) and slidably mounted in said guides is a vertically disposed cutting bit B, the body portion ot which extends transversely of the frame A and is adapted to cut one end of the hinge seatwhen actuated. The bit B is provided with portions b extending substantially at Yright angles from the sides thereof and the lower edges of said extensions b are sharpcned to form cutting edges which extend from the ends of the cutting edge of the bit proper and fo 1m a continuation thereof, so that the actuation of said bit will insure the hinge scat being cut with a square corner. the forward face of the bit B is provided with a lug b2, which is adapted to engage a spring b3 which is supported upon the base a of the frame of the tool, said spring serving to normally maintain the bit in an elevated position with the cutting edge thereof positioned above the plane of the lower edges of the lugs 0.3 at the ends of the tool so that when the tool is placed upon the work the bit will not contact therewith until properly actuated. The upper ends of the portions Zi of the bit B are adapted to abut against the under side of a cross bar b4 connecting the upper portions of the walls a? of the frame and thereby limit the upward movement of the bit B in the `guides b.
The inner faces of the walls a2 of the frame of the tool are provided at one side of the guides b with the inclined guides o, in which is movably supported a bit C, the cutting edge of which is adapted when the bit is moved downwardly in its guides to be brought into proximity to the cutting edge of the bit B to cut out the chip previously scored thereby, as will be hereinafter pointed out. The upper surface of the bit C is provided with a lug c which is adapted to engage a spring c2 which is supported in any suitable manner, said spring serving to normally maintain the bit C in an elevated and inoperative position above the work. The upper ends of the guides o are closed to form stops against which shoulders on the bit C abut to limit the upward movement thereof.
The front wall of the frame of the t'ool is provided on its outer face adjacent the bit B with a pair of vertically disposed guides d in which is slidably secured a tool carrier D. The tool carrier D comprises a vertically disposed portion Z which is slidably secured between the guides Z and a horizontally disposed portion Z2 which projects outwardly from the lower end of said vertically disposed portion. The horizontally disposed portion d2 of the tool carrier D is provided on its under side with a pair of guides d3 extending lengthwise thereof, in which is slidably secured a cutting bit D. The vertically Adisposed .portion d of the tool carrier feo Dis provided with a vertically extending slot di* therein,v through which projects the threaded end of a bolt d5, which is secured in the front wall of the frame of the tool. The projecting end of the bolt Z5 has threaded thereon a thumb nut (Z6 and from this construction it' will be apparent that the tool carrier D can be readily adjusted and locked in any desired position in the guides d to vary the depth of the mortise desired to be cut.
E designates a head Vwhich is slidably secured between the walls a2 of the frame and is adjustable towards and away from the cutting bit B. The head E comprises side walls e, which aredesigned to fit snugly against the inner faces of the walls a2 of the frame, and the top plate e', which is arranged to rest upon the upper edges of the walls of the frame. `Secured in the side walls e of the head E and projecting outwardly therefrom are bolts e2, the threaded ends of which project through longitudinal slots a4 formed in the walls a2 of the frame of the tool and have threaded thereon suitable thumb nuts c3, so that the head may be clamped in any desired position of adjust- .nient in the frame. Y
Slidably secured in the head E is a vertically disposed cutting bit F which is provided with portions extending at right angles from the edges thereof, the lower edges of which are sharpened to form a continuation of the cutting edge of the bit proper, said bit being similar in construction to the bit B hereinbefore described. The bit F is normally held in its elevated position by a spring f interposed between a lug f2 secured to the front thereof and lugs f3 projecting from the sides of the frame E. The upward movement of the bit F in its guides is limited by the upper edges of the portions f thereof coming into contact with the under side of the top plate c of the frame E.
Slidably secured in inclined guides formed on the inner surface of the side walls e of the frame E is a bit Gr, which is similar in construction to the bit C hereinbefore described and is designed to coperate with the ing from one edge thereof a pair of vertically disposed guides L, which are designed tolle along sidev of the outer surface of the front wall of the frame of the tool, and slidably secured in the guides /L is a tool carrier H, which is similar in constructionV to the tool carrier D hereinbefore described. A horizontally disposed bit H is slidably secured in the tool carrier H in the same manner in which the bit D is secured in the tool carrier' D. lThe' vertically disposed portion of the tool carrier H is provided with a vertically extending slot /i through which one of the bolts e2 hereinbefore referred to extends, from which it will be apparent that the same thumb nut e3 which serves to lock the head E in its adjusted position also serves to lock the tool carrier H in any desired position of adjustment.
The inner face of the rear wall a2 of the frame of the tool is provided on opposite sides of the opening in the base thereof with two pairs of vertically disposed guides, in which are slidably mounted the cutting bits I, the lower ends of which project through suitable slots formed in the base a of the frame of the tool. rlhe outer faces of the bits l are provided with lugs c" which engage springs supported in any suitable manner upon the base a of the frame of the tool, said spring serving to normally maintain the bits l in their elevated or inoperative position. The guides e' are closedv at their upper ends to form stops which cooperate with shoulders on the blades i to limit the movement of said blade in said guides.
The bottom plate a of the frame of the tool is provided beyond the bits 1 with two pairs of guides il: extending transversely there across and slidably secured between the guides 7s are two plates K. the rear ends of which project through suitable openings formed in the rear wall a2 of the frame of the tool and terminate in the upwardly extending portions 7c. The plates K are locked in any desired position of adjustment by means of thumb screws 7c* provided with threaded Shanks k3 which project through slots /32 xtending longitudinally of the plates K and engage threaded openings in the base c of the frame of the tool.
rfhe upwardly extending portions fb of the plates K are provided adjacent their upper ends with vertically disposed sleeves Z in which are loosely mounted the vertically extending gage bars L. The sleeves Z are provided with suitable set screws z" for holding the gage bars in various positions of adjustment therein. The vertically extending portions 7a of the plates K form a straight edge which extends at right angles to the base of the frame of the tool so that when the gage bars L are clamped thereto they will also extend at right angles to the base of the frame of the tool.
Having described the construction of my improved tool, I will now set forth the manner of using the same:
Y The door is first fitted to the jamb and both door and jamb marked to indicate the position of the hinge seats which are to'be cut therein. To cut the hinge seats in the j amb, the head E is adjusted in the frame A until the distance between the bits F and B is equal to the length of the hinge seat which is to be cut. The tool carriers H and I) are then adjusted according to the depth of the mortise which is to be cut. The gage bars L are then elevated so that no part thereof projects below the sleeves Z and are secured in this position. The tool is then placed in the rabbet orp the jamb with the backs of the upwardly extending portions lo of the plates K abutting against the edge of the rabbet. rhe thumb screws 7st are loosened and the trame of the tool is adjusted relative to the plates K until the proper width for the mortise is obtained, when said thumb nuts are tightened. To out each mortise or hinge seat, place the tool on the jamb with the bits F and B overlying the lines which have been marked to indicate the ends of the particular hinge seat which is to be cut, and with the tool in this position strike on the bits F and B, which has been previously pointed out have been adj ted to give the proper length to the mortise; then strilre the bits C and G to cut out the chips previously scored by bits i? and B; then move the tool longiinaily ot the amb in either direction a ht distance at a time, and in each position to which the tool is shifted strilre iirst whichever one of the perpendicular bits F and B that stili remains within the lines of the niortise to be ci. and then on the proper inclined bit to remove the chip which has beenV scored by the perpendicular bit. rccording to i @ther the bit F or B is struck will ot course cepend upon the direction in which the tool shifted on the jamb. rihe l-'act that either bit may be utilized, however, is of importance, inasmuch as frequently the hinge seats are placeo so close to the bottom and top ot the door jamb that it would be possible to move the tool on the jamb in one direction to a limited extent only.
In cutting the mortise the longitudinal movement of the frame on the jamb may be continued in one direction -until the entire length of the mortise has been out, or until about one-halt oi the mortise has been cut. En the latter case, the frame is first moved baci; to its original position and then moved longitudinally in the opposite direction to diiierent positions on the jamb, the other of the vertically disposed bits F and B, together with its corresponding inclined bit being utilized to cut the mortise. After the mortise has been scored by either or both of the bits F and G and their corresponding inclined bits, in the manner above described, the back ot the mortise is scored by the actuation of either of the back bits I, the frame being i'irst moved to bring the desired bit into proper position. After the mortise has been scored and the back cut in the manner above described, the frame oi' the tool is then shifted to bring either of the horizontal bits H and D into position to remove the chips previously'scored. Generally, but one of the baclr bits I and one of the horizontal bits H or D are utilized to cut the back of the mortise and to remove the chips scored, but, as has been heretofore pointed out, it frequently happens that in cutting mortises in jambs, the longitudinal niovement permitted the trame ot' the tool in one direction is insuthcient to permit the entire mortise to be traversed by a single bit, in which case, the frame can be moved longitudinally in the opposite direction and the other bit of the same character brought into position to cut the remainder ot' the mortise. The hinge seats on the door are cut in exactly the same manner except that the gage bars L are lowered and secured in the sleeves Z so that the inner faces thereof will engage with one side of the door and serve to support the tool in the proper position thereon as is shown in F ig. l of the drawing.
l do not desire to limit myself to the precise form and construction shown in the drawings, as it is obvious that many minor changes might be made thereto without departing` from the-spirit orn the invention as defined in the appended claims.
