SPECIFICATION forming part of Letters Patent No. 554,333, dated February 11, 1896. Application filed July 81, 1893. Serial No. 482,041, (No model.)
To all whom it may concern.-
Beit known that I, TRUMAN D. COOK, a citizen of the United States, residing at Topeka, in the county of Shawnee, in the State of Kan-. sas, have invented certain new and useful Improvements in Carving, Routing, and Mortising Machines, of which the following is a specification.
My invention relates to improvements in carving, routing, and mortising machines in which a boring and routing bit is used to produce routing, mortises, tenons, rabbets, chamfers and the like; and the objects of my improvements are, first, to provide a means by which, while the frame carrying the bit is stationary, the material to be operated upon may be carried about, under, and against the bit in such manner that the bit may at all times out with precision and accuracy to a line determined by the line of the pattern, regardless of the size of the bit; second, to provide an adjustable compensating guide-pin adapted by its adjustment to compensate the loss in diameter of the bit due to Wear and sharpening, that with a given pattern and bit the lateral dimensions of the routing, &c., may be we actly retained; third, to provide a patternlooard having the pattern so constructed therein with reference to the guide-pin that when the line of the pattern follows the guide-pin the routing, &c. of the desired lateral dimensions, shall be produced in the material regardless of the size of the guide-pin and of the bit; fourth, to provide means for securing the guide -pi11 adjustably in the operatingtable; fifth, to provide an adjustable guidepin adapted by its adjustment to the production from a given pattern of the routing, &-c. of any desired lateral dimensions, without regard to the lateral dimensions of the pattern or the size of the bit.
My improvements are made with special reference to my patented carving and routing bit, Letters Patent for which were granted to me April 20, 1886, No. 340,100, or they may be used with any other bit of like character and operation.
I obtain the objects of my invention by the mechanism illustrated in the accompanying drawings, in which- Figurel is an isomctrical projection of the machine with part of the table removed, as
indicated by the dotted lines, showing the working parts underneath and in detail. Fig. 2 is a vertical projection. with cross-section, showing the manner of securing the bit and guide-pin and their respective working parts. Fig. 3 is a cross-section of the bit and chuck in which it is secured. Fig. 4 is a cross-section of the guide-pin, showing the manner of its operations and of securing it to the table. Fig. 5 is same as Fig. 4, except that it shows a straight guide-pin. Fig. 6 is a pattern-board in perspective, showing a pattern therein.
I preferably use the tapering guide-pin shown in Fig. 4, but do not limit myself to anyparticular or peculiar size or shape of pin.
Similar figures refer to similar parts throughout the several views.
1 is a floor-plate resting upon and adapted to be secured to the floor.
2 2 are the posts or standards upon which are mounted the arms 3 3, having the terminal bearings 4 4, in which is journaled the vertical shaft 7. The shaft is provided between the bearings with the pulley 5 and at its lower end bears the chuck 8, in which is set the boring and routing bit 9, secured therein by the set-bolt 27. Power is transmitted through the belt 6, passing around the pulley 5 ,over the pulley 43,supported by the bracket hanger 42, and alike pulley on the opposite side of the posts (not shown in the drawings) and about the band-Wheel 44, carried on the driving-shaft 45, one'of the bearings of which is shown at 46. The shaft 7 and its bit 9 may be driven at as high a rate of speed as ten thousand revolutions per minute, though for regular steady work four thousand to five thousand revolutions are sufficient.
To the standards is secured the plate 1:2, the lateral edges of which extending beyond the standards are clasped by the embracing vertical arm of the table-support 11, adapted to slide up and down thereon and upon its horizontal arm, carrying the table 10. Upon the table is supported the pattern board or form 47, having the handles 48, the horizontal part of which also secures the material to the board, the slot 49 of the pattern it is desired the bit should follow and produce in the material to be operated upon, and the cars 51 to retain the material in position.
23 is the guide-pin set in a depressed recepta-cle in the upper bedplate 22, which is set in the table so that its upper face is flush with the face of the table. The depth of the guide-pin in the receptacle is determined by the set-bolt 21 entering the receptacle from below and upon which the pin rests, said bolt being threaded into the lower part of the bedplate and provided with a hand-wheel 25.
22 is the under bed-plate.
26 is a nut-lock provided with a handle. hen tightened up, it secures the plates to the table by compression of the table between the shoulder of the upper and the edge of the lowerbed-plate. Being set upon the set-bolt, when tightened it securely locks the bolt and prevents it loosening by the jar of the machinery. The table is adjustable vertically to determine the depth the bit shall enter the material. This adjustment is effected by means of the engagement with the rack 12 on the vertical arm of the table-support of the ratchet 1i on the vertical arm 13 of the reciprocating lever 15, having its fulcrum at 16 upon the floor-plate and provided with the foot-plate 16, said lever working between the upright guides 17, and its action in the vertical adjustment of the table being regulated by pins in said guides. The ratchet 14 is detained in its engagement with the rack 12 by the flat spring 18, secured to the under side of the horizontal arm of the table-supp ort and to the vertical arm of the lever by the bolt 50 sliding between the two parts of the arm, and is released by means of the rod 19, havingits inner end secured near the extremity of the fiat spring, and provided with the teeth or rack 20, engaging the edge of the opening in the hanger 21, through which it passes.
The more exact adjustment of the table is effected by means of the vertical screw 28, the lower end of which rests in the foot-step 29, secured by the plate 30 to the standards. The screw of the gage threads in the receiver 81, secured in the bracket 32, attached to the vertical rack-arm of the table-support. At its upper end it passes through the sleeve 35 set in the bracket extension 31 of the arm 33, and is provided with the gear -wheel 36, loosely keyed thereto to admit of the vertical passage of the shaft through the wheel. The gear-wheel 3G meshes with the gear-wheel 37 011 the shaft 38, journaled at its inner end in the bearing 37 and at its outer end in the bearing 39 on the extremity of the arm 3 and provided with the wheel 10 having the handle 41.
In the operation of my improved machine any design required or desired may be laid off in the pattern-board, and the material being secured to the board the bit acting directly over the pin and the pattern following the pin, if the pin and the bit be all of the same dimensions the pattern is exactly reproduced in form and dimensions in the material, the depth to which it is out being determined by the vertical adjustment of the table. If, however, it is desired to cut a furrow, routing-rabbet, or other form in the material of greater lateral dimensions than the diameter of the bit, it may be done without changing the bit by the use of my adjustable tapering guide-pin. Thus the pattern-slot and the bit remaining the same, the tapering guide-pin. being depressed in its receptacle by resetting the set-bolt, the edge of the pattern-slot is allowed to pass laterally until the bit cuts to the desired line on one side. Then reversing the direction of the movement of the patternboard and passing the other edge of the pattern-slot along the guide-pin the bit will cut to the desired line on that side also and the pattern in the pattern-board will be reproduced in the material of the width desired. This constitutes a second very important advantage in my improvement.
A third very important ad vantage obtained by my tapering guide-pin is that when the bit becomes worn by use and sharpening, by depressing the pin by lowering the set-bolt this loss is compensated and the line of the pattern brought true to the line of the bit, and the pattern perfectly and exactly reproduced in the material secured on the patternboard under the bit, whereas without this adjustment of the guide-pin the line produced by the bit would vary from the line of the pattern according to the wear of the bit, and the bit have to be replaced by a new one. 1 preferably use the tapering guide-pin shown in Fig. 4. I, however, reserve the right to use a straight pin, as shown in Fig. 5, or any other form of pin adapted to the use required, not intending to limit my invention to the form of pin.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a carving, routing, and mortising machine a guide-pin set in a depressed receptacle of an upperbed-plate and adjustable therein by a set-bolt entering the plate from below an under plate partly encircling the upper plate, a nut-lock carried on the set-bolt securin g the plates to the table and locking the setbolt, with the vertically-adjustable table and pattern-board carried thereon in combination substantially as shown and described, and for the purposes specified.
