HUNT, OF CINCINNATI, OHIO, ASSIGNORS TO THE G. A. GRAY COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO PLANER HEAD Application filed October 9, 1925. Serial No. 61,552.
Our invention relates generally to planer heads and in combination with planer heads, particularly to improvements in the methods of swiveling and clamping the tool box or clapper box on to the saddle of a planer.
It is the object of our invention to provide means for easily and quickly swiveling the tool box so that the tool may be made to swing in a plane having any desired angle with the line of travel of the slide to which the tool box is clamped. It is also our object to provide means to readily and quickly clamp the tool box fast to the slide after the box has been swiveled to the proper position. A further object of our invention is the provision of more room back of the upper part of the shank of the tool, so that the tool can swing further back when it lifts on the return stroke.
Figure 1 is a front view of the slide, tool box, and clamping mechanism, forming part of the rail head of a planer.
Figure 2 is a section through the slide and tool box on line 22 in Figure 1, showing the arrangement of the mechanism.
Figure 3 is a section on line 3-3 in Figure 1 showing the construction of the clamps and clamp screws.
In the drawings the cross rail of the planer is provided with a slidably gibbed saddle 1. Upon the saddle 1 is mounted a swiveling guide 2, commonly called a swivel or harp, to which is slidably gibbed slide 3. The slide 3 is actuated by suitable mechanism so that it can be made to move in a vertical or angular direction along the harp. To the slide 3 is ,fastened a casting 4 commonly known as a tool box or clapper box. This casting is fastened to the slide by a screw 5 in such-a mannor that it can swivel about the screw. To this box is pinned a block or clapper 6, in such a manner that it can swing outwardly on the return stroke of the planer. To the block or clapper is clamped a tool 7 by means of suitable bolts or clamps. So far all the parts mentioned are usually used on planers, and are well known in the art.
The upper part of the box a is in the form of a plate, fiat on both sides, with its edge forming a circular are having its center at the axis of the screw 5. In this edge are cut a sector of gear teeth 8, which mesh with coacting teeth out in a gear 9, which turns about pin 10, which is fastened to slide 3. This gear 9 is an idler and meshes with gear 11, which turns similarly on pin 12. Gear 11 is also an idler and meshes With pinion 13 which is cut integral with a long hollow shaft 13A, which is journaled in hole 3A, bored in slide 3. In the specification following we will refer to the pinion 13 and the shaft 13A as the shaft and pinion. If desired, the idler gear 11 and the pin 12 could be omitted, and the idler gear 9 made larger so as to mesh with both the teeth on the edge of the tool box and those on the shaft and pinion. However, a
better proportioned mechanism is usually obtained by using two idlers. Within the hollow shaft and pinion, solid shaft l lslides in and out. To the end of solid shaft 1 1 is keyed hand wheel 15. Solid shaft 14 is also slidably keyed to the shaft and pinion. By this means the wheel 15 can be made to slide in or out, but when the wheel is turned it causes the shaft and pinion to turn,which in turn causes the gears 11 and 9 to revolve, and thus swivels the tool box 4 about the screw 5. Handwheel 15 is placed on the sliding shaft 14: instead of directly on the shaft and pinion 13, so that it may be pushed in out of the way in order to place clamp screws 17,17, which are screwed into the clamp 18. It should be noted that because of the clearance between the bushings 16 and the screws 17, and because the co-acting surfaces between the bushings and the screws are concentric spherical portions 16A and 17 A, that the clamp 18 can move slightly, and that if the upper end of the clamp 18 be moved to the left as indicated in Figure 2 the lower end will clamp the upper portion of the tool box firmly betweenitself and the slide 3.
In order to effect this clamping action. we
provide a threaded hole 18A at the upper end of the clamp 18. In this we place a hollow screw 19 which is keyed fast to handwheel 20 and bears against a washer 21 which is interposed between the hollow screw 19 and the shaft and pinion. By turning the handwheel 20 in a clockwise direction as seen-in Figure 1, the hollow screw 19 will advance inward, forcing the shaft and pinion against the slide 3. This will prevent the shaft and pinion from rotating, and thus by means of the gears 13 and 9, the tool box 4: will be prevented from swiveling about the screw 5. At the same time the pressure of the thread of the hollow screw 19 will push the top of the clamp 18 to the left as seen inFigure 2, causing it to pivot on the 's'crews 17'-17, and to clamp tightly the upper part of'the tool box or clapper box, the face 18Bof clamp 18bei'ng forced into contact with face 413 of the tool box, thus clamping the box firmly between the clamp :18 and the'slide3.
It may be noted "that the bore of the hollow screw 19 is somewhat larger than the outside diameterof the shaftof the shaft and pinion, so that there can be relative motion between them without binding.
Also it will be'evident that the lever 18 is 'a lever of the first class, which enables us to gain 'mtich greater power at the clamping point and permits of the use of a single operating member whereas in the past it has been necessary to use two clamping "screws where we use two pivot'screws.
