ARTHUR O. VAN HOUIVELING, OF PELLA, IOWA.
KEY-SEAT CUTTER.
SPECIFICATION forming part of Letters Patent No. 683,868, dated October 1, 1901.
Application filed March 11, 1901. Serial No. 50,606. (No model.)
To all whom, it may concern.-
Be it known that I, ARTHUR O. VAN HOU- WELING, a citizen of the United States, residing at Pella, in the county of Marion, State of Iowa, have invented certain new and useful Improvements in Key-Seater Attachments for Planing or Shaping Machines, of which the following is a specification.
The objects of my invention are, first, to
provide a device of simple, strong, durable, and inexpensive construction that may be readily, quickly, and easily applied to a planer or shaper of the ordinary kind for the purpose of cutting keyways in pulleys, &c.
A further object is to provide a device of this class in which the cutting-tool is firmly and immovably held during both the effective and the return strokes,whereby a maximum of accuracy in cutting a key-seat is attained.
.A further object is to provide simple and antomatically-operating means whereby the cutting-tool is relieved upon its return stroke from engagement with the work, so that said cutting edge will not be dulled by travel on its return stroke in engagement with the work.
A further object is to provide a cutting-tool of such shape that when dulled or worn off by constant use it may be sharpened until a considerable portion of the tool has been used up; and my object is, further, to provide a device of this class in which the cutting-tool is firmly held and the adjusting means whereby the depth of cut is determined is entirely independent and separate from the cuttingtool. Hence the depth of cut may be quickly and easily set by the operator at any time without affecting the fastenings of the cutting-tool.
My invention consists in certain details in the construction, arrangement, and combination of the various parts of the attachment and in the combination thereof with a planer or shaper, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 shows in side elevation a portion of an ordinary planer or shaper having my attachment applied thereto and showing a pulley on the attachment, said parts being in position for cutting a keyway in said pulley. Fig. 2 showsin perspective that portion of the attachment connected with the toolhclder of the planer or shaper. Fig. 3 shows a vertical longitudinal sectional view of the mandrel upon which the work is placed, showing a groove therein of uniform depth. Fig. 4 shows a like View of a modified form in which the groove is tapered, and Fig. 5 shows in side elevation the cutting-tool and its adjusting-wedge.
Referring to the accompanying drawings, I have used the reference-numeral 10 to indithe frame of the planer or shaper. ll indicates the table of said machine, upon which the work is usually placed, and 12 indicates the reciprocating carriage, to which the toolholder 13 is fixed.
My attachment comprises, first, an upright 14, having a forked lower end 15, in which a set-screw 16 is placed. This part 14 is designed to pass through the opening in the tool-holder 13, which is provided, for holding the tools used in planing or shaping, and the set-screw 17 serves to hold the parts 14 firmly and immovably in position. Above the part 13 a yoke 18 is fixed to the upright 14 to project horizontally therefrom, and the side pieces 19 are fixed to the forward end of this yoke. Between the upper ends of the side pieces 19 is a pivoted block 20, having the central screw-threaded opening designed to admit a screw-threaded rod 21. On the forward end of the rod.2l is a handle 22, and the rear end of said rod is pivotally mounted in a link 23, which link is pivoted to the top of the upright 14. Obviously a manipulation of the handle 22 will force the top ends of the side pieces 19 either toward or away from the upper end of the upright 14.
The body of the cutting-tool is indicated by the reference-numeral 24, and it is designed to enter the lower end of the upright 14 and be firmly secured thereto by the setscrew 16. At the forward end of the cuttingtool is the cutting-point, which inclines forwardly and downwardly at 25, the top surface of the cutting-tool being preferably straight and flat. The wedge, whereby the position of the on tting-tool is adjusted, comprises a body portion 26, flat onits underside,except near its forward end, where it is provided with a downwardly and forwardly inclined surface 27. In its bodyportion is a slot 28 for pu rposeshereinafter made clear. This cutting-tool-adj usting device is placed above the cutting-tool, and a pin or bolt 29 passes through the lower end of the parts 19 and through the slot 28, and the rear end of the part 26 passes through a rigid arm 30 on the carriage 12, and an extensile coil-spring 31 is placed thereon, with one end in engagement with the part 30 and the other end in engagement with a nut 32, adjnstablyseeured to the rear end of the part 26. By this means the cutting-tool-adjusting device is normally held to the forward limit of its movement, and yet it may move rearwardly a slight distance against the pressure of the spring, said movement being limited by the length of the slot 28.
The means for holding the work comprises a part 33, fixed to the table 11, a support, and a mandrel 34, said mandrel being provided with a longitudinal groove 35 on its under surface. here the keyseat is to be made straight, the mandrel shown in Fig. 3 is used, and where the key-seat is to be tapered the mandrel shown in Fig. +t is substituted, it being understood that the travel of the cutting end of the cutting-tool is confined within the limits of the groove 35 in the mandrel 34. A spring 36 is fixed to the top of the table 11 and normally engages the under surface of the cuttingtool to exert a yielding pressure in an upward direction thereupon.
In practical use the attachment may be readily connected with a planer or shaper by placing the upright lat in the tool-holder of the reciprocating carriage and by placing the part 33 upon the work-table 11. Then when the parts are adjusted and a pulley or the like placed on the mandrel 34: the handle 22 is manipulated to force the parts 26 forwardly or backwardly until the point of the cutting-tool engages the interior of the pulley-hub in proper manner. Then the reciprocating carriage is made to advance, and during its forward movement the cuttingtool will make its first effective movement, the wedge 27 being firmly held in place during this effective movement by the pin or bolt 29 engaging the front surface of the slot 28. During the return stroke the cutting-tool will first move rearwardly until the limit of movement of' the pin 29 in the slot 28 has been reached. Then the parts will move rearwardly or on the return stroke to gether. However, the slight movement permitted by the slot 28 is amply sufficient to relieve the cutting tool from engagement with the work. Furthermore, the spring 36 serves to elevate the cutting-tool and prevent it from rubbing against the work on its return stroke. \Vhen it is desired to cuta tapered key-seat, the mandrel shown in Fig. t is substituted for that shown in Fig. 3, and obviously the cutting-tool may be readily sharpened whenever dulled until a considerable portion of the tool is used up in this process.
Having thus described my invention, what I elai In, and desire to secure by Letters Patent of the United States therefor, is-
1. A key-seating attachment for planers or shapers, comprising a support to be attached to the machine-carriage, a cutting-tool connected with the support, a frame adjustably connected with the support, a wedge carried by said frame, to engage the cutting-tool, means for connecting the wedge to the frame, whereby a limited sliding movement is permitted, a yielding pressure device to normally hold the wedge to one limit of its movement, and a longitudinally-slotted mandrel to receive the work and to permit the wedge and tool to reciprocate in its slot, for the pur-' poses stated.
2. A key-seating attachment for planers or shapers, comprising in combination a support detachably connected with the reciprocating carriage of the machine, a cuttingtooldetachably and adjustably fixed to the lower end of said support, to project horizontally, and having its cutting edge inclined forwardly and downwardly, a brace fixed to the support, a frame pivoted to said brace,
means for tilting said pivoted frame, a wedge connected with the lower end of the frame, so as to be capable of limited sliding movement with relation to the frame, a spring for normally holding the wedge to its rearward limit of movement, a mandrel having a 1011- gitudinal slot and connected with the machine-frame to receive said wedge and cutting-tool, substantially as, and for the purposes stated.
